10 years of transition in Ukraine agriculture: An analysis of productivity and efficiency of enterprises
Provedor de dados: 31
Autores: Lissitsa,   Alexej; Odening,   Martin; Babycheva,   Tamara.
This paper analyzes efficiency and total factor productivity (TFP) change of large agricultural enterprises during their transition to a market economy in Ukraine. In this case the efficiency is calculated by data envelopment analysis and the productivity change is measured by the Malmquist Productivity Change Index in the period between 1990 and 1999. On average, TFP declined by 6% annually, dropping a total 42%. The main reason for the observed TFP decline is a decrease in technical efficiency, which is found to be remarkably significant. At the same time there is a high variation among individual enterprises: their distribution of efficiency scores widens, which indicates that the farms diverge with respect to their economic performance. The Tobit...

11[beta]-hydroxysteroid dehydrogenase-type 2 evolved from an ancestral 17[beta]-hydroxysteroid dehydrogenase-type 2
Provedor de dados: 17
Autores: Michael E. Baker.
11[beta]-hydroxysteroid dehydrogenase type-2 (11[beta]-HSD2) regulates the local concentration of cortisol that can activate the glucocorticoid receptor and mineralocorticoid receptor, as well as the concentration of 11-keto-testosterone, the active androgen in fish.  Similarly, 17[beta]-HSD2 regulates the levels of testosterone and estradiol that activate the androgen receptor and estrogen receptor, respectively.  Interestingly, although human 11[beta]-HSD2 and 17[beta]-HSD2 act at different positions on different steroids, these enzymes are paralogs.  Despite the physiological importance of 11[beta]-HSD2 and 17[beta]-HSD2, details of their origins and divergence from a common ancestor are not known.  An opportunity to understand their evolution is...

125000 ans d'enregistrements récifaux des stagnations du niveau de la mer dans l'Océan Indien (Archipel des Glorieuses)
Provedor de dados: 5
Autores: Jorry, Stephan; Jouet, Gwenael; Le Roy, Pascal; Prat, Sophie; Camoin, Gilbert; Vella, Claude; Caline, Bruno.
Suite à l’initiation du programme REEFCORES (REEFs and CORals form the EparseS), deux missions menées en 2011 et en 2013 dans l’Archipel des Glorieuses (Nord Madagascar) ont permis de documenter les empreintes des épisodes de déglaciation dans la morphologie des terrasses récifales émergées et submergées. L’objectif principal de cette étude est d’abord de documenter les stagnations du niveau marin qui ont été engendrées au cours de la dernière remontée du niveau marin et sur les terrasses du dernier interglaciaire (MIS 5e). Cette zone située autour des Seychelles, du fait de sa stabilité (isostasie très faible), est idéalement placée pour reconstituer avec précision les variations globales du niveau marin (Milne and Mitrovica, 2008).

New sequencing technologies make it possible to achieve genome sequence fast and cheap. Since the assembly step of such next generation reads is still not well standardized it is the most cumbersome part of sequencing projects. &amp;#xd;&amp;#xa;We present here approaches undertaken on the way to the draft assembly the cucumber (Cucumis sativus L. cv. Borszczagowski) genome done with the use of 8x unpaired and 4x paired (3 Kbp) pyrosequenced 454 XLR Titanium reads, together BAC library ends fragments (12,7x physical coverage). Two different assembly approaches, namely Celera and Celera/Arachne were finally used. The Celera result was 15&amp;#x2019;196 contigs of 197 Mbp length and N50 27&amp;#x2019;086 bp and 4&amp;#x2019;157 scaffolds of 224 Mbp length...

15Nitrogen transfer from legumes to neighbouring plants in multi-species grassland
Provedor de dados: 21
Autores: Pirhofer-Walzl, K.; Høgh-Jensen, H.; Rasmussen, J.; Rasmussen, J.; Søegaard, K.; Eriksen, J.
This study investigates the N transfer from legumes to  neighbouring plants, grasses, legumes and herbs in a temperate grassland. In a field experiment white clover  (Trifolium repens), red clover (Trifolium pratense) and lucerne (Medicago sativa) were leaf-labelled with 15N enriched urea. The 15N tracer was measured in above-ground plant tissue of eight neighbouring plants in two subsequent harvests in 2008. The three legumes donated 15N to all neighbouring plants, of which grasses, white and red clover were strong receivers. Results show that N transfer increases with N application and from the 1st to the 2nd cut.

15Nitrogen uptake from shallow- versus deep-rooted plants in multi-species mixtures and monoculture grassland
Provedor de dados: 21
Autores: Pirhofer-Walzl, K.; Høgh-Jensen, H.; Rasmussen, J.; Rasmussen, J.; Søegaard, K.; Eriksen, J.
Only few studies have explored the importance of functional diversity in temperate agricultural grasslands in relation to nitrogen (N) uptake. This study investigates the consequence of growing deep-rooted plants together with grass-clover mixtures in terms of N uptake efficiency from deep soil layers. The objective was to compare the N uptake of the shallow-rooted grassland species Lolium perenne and Trifolium repens; and the deep-rooted species Cichorium intybus and Medicago sativa in monocultures and mixtures. We hypothesized that growing deep-rooted plant species in mixture with shallow-rooted species increases the N uptake from deep soil layers partly through competition. A 15N tracer study was carried out with 15N enriched ammonium-sulphate placed at...

15N-labeled glyphosate synthesis and its practical effectiveness
Provedor de dados: 63
Autores: Tavares,Claudinéia Raquel de Oliveira; Bendassolli,José Albertino; Ribeiro,Daniela Neves; Rossete,Alexssandra Luiza Rodrigues Molina.
Glyphosate is the herbicide with the greatest participation in the world market, and it has been used intensively in agriculture for over 30 years, especially because of its relatively low cost and high effectiveness on different species. This study describes a synthesis method of glyphosate in the form of the isopropylamine salt enriched in the stable nitrogen isotope (15N). The 15N-herbicide synthesis was performed using a phosphomethylation reaction with dialkyl phosphite and 15N-glycine. The tests were conducted at a microscale and equimolar quantities. A 20% yield was obtained at the established conditions. To test the effectiveness of the synthesized glyphosate, an experiment was performed in a growth chamber with the weed Lolium multiflorum...

16S rRNA gene-based molecular analysis of mat-forming and accompanying bacteria covering organically-enriched marine sediments underlying a salmon farm in Southern Chile (Calbuco Island)
Provedor de dados: 72
Autores: Aranda,Carlos; Paredes,Javier; Valenzuela,Cristian; Lam,Phyllis; Guillou,Laure.
The mat forming bacteria covering organic matter-enriched and anoxic marine sediments underlying a salmon farm in Southern Chile, were examined using 16S rRNA gene phylogenies. This mat was absent in the sea bed outside the direct influence of the farm (360 m outside fish cages). Based on nearly complete 16S rRNA gene sequences (-1500 bp), mat-forming filamentous cells were settled as the sulphur-oxidizing and putatively dissimilative nitrate-reducing Beggiatoa spp., being closely related (up to 97% sequence identity) to Beggiatoa spp. identified in eutrophic shallow sediments in northern Europe (Danish Limfjorden and German Dangast inlets). Their phylogenetic affiliation was consistent with their morphology as vacuolated and sulphur-containing cells...

1-Methylcyclopropene and Aminoethoxyvinylglycine effects on yield components of field-grown cotton
Provedor de dados: 64
Autores: Brito,Giovani Greigh de; Ferreira,Alexandre Cunha de Barcellos; Borin,Ana Luiza Dias Coelho; Morello,Camilo de Lelis.
Biotic and abiotic stresses can alter the hormone balance and trigger the activation of pathways involved in the cotton stress responses, resulting in the abscission of squares, flowers and young bolls and consequent reductions in the seed cotton yield and fiber yield. As part of the mechanism that primarily regulates the protective response of plants against stresses, ethylene is considered a key hormone involved in this response, and increased ethylene synthesis has been observed when plants are subjected to stress. Thus, the development of strategies aimed to mitigate their negative effects can reduce the shed rate of reproductive structures and positively impact cotton productivity. For this purpose, 1-methylcyclopropene (1-MCP), a compound that...

2001 NORTH DAKOTA AGRICULTURAL OUTLOOK: REPRESENTATIVE FARMS 2001-2010
Provedor de dados: 31
Autores: Taylor,   Richard D.; Koo,   Won W.; Swenson,   Andrew L.
Net farm income for most representative farms in 2010 will be lower than in 2000.  Low profit farms, which consist of 25% of the farms in the study, may have  negative net farm income throughout the forecasting period, and may not have financial resiliency to survive.  Cropland prices and cash rental rates are projected to increase slightly except in the Red River Valley where they are projected to fall.  Debt-to-asset ratios for most farms will increase slightly throughout the forecast period.  Debt-to-asset ratios for the low profit and small size farms are higher than those for large and high profit farms.

2001 OUTLOOK OF THE U.S. AND WORLD SUGAR MARKETS
Provedor de dados: 31
Autores: Koo,   Won W.; Taylor,   Richard D.
This report evaluates the U.S. and world sugar markets for 2000-2010 by using the Global Sugar Policy Simulation Model. This analysis is based on assumptions about general economic conditions, agricultural policies, population growth, weather conditions, and technological changes.  Both the U.S. and world sugar economies are predicted to improve over the next ten years after the current over supply is reduced. World demand for sugar is expected to grow faster than world supply, resulting in gradually increasing Caribbean sugar prices from 8.51 cents/lb in 2000 to 12.67 cents/lb in 2010. The U.S. wholesale price of sugar is projected to increase from 22.5 cents/lb in 2000 to 26.6 cents/lb in 2010, if the United States maintains its sugar programs. World...

This report evaluates the U.S. and world wheat markets for the 2000-2010 period by using the Global Wheat Policy Simulation Model.  This analysis is based on a series of assumptions about general economic conditions, agricultural policies, weather conditions, and technological change.  Both the U.S. and world wheat economies are predicted to be improving for the next ten years.  World demands for both common and durum wheat are expected to grow faster than world production of the two wheat classes, resulting in gradual increases in prices of the wheats, which are predicted to increase 5.3% for durum wheat and 1.1% for common wheat for the 2000-2010 period.  World trade volumes of both classes of wheat are expected to expand, but trade volume of durum wheat...

2009 Annual Report of the Southwestern Minnesota Farm Business Management Association
Provedor de dados: 31
Autores: Nordquist,   Dale W.; Kurtz,   James N.; Nitchie,   Donald L.; Paulson,   Garen J.; Froslan,   Janet M.; Christensen,   James L.
Average net farm income was $69,787 in 2009 for the 95 farms included in this annual report of the Southwestern Minnesota Farm Business Management Association.  Average earnings decreased by 63%  from $190,901 in 2008.   This continues the downward trend that began in 2008 after six years of steady increases.  As expected, low incomes for virtually all types of livestock operations pulled the average down, and some livestock farms sustained large losses.  Crop farms, on average, were profitable but also earned much lower incomes compared to recent years. Median net farm income, or the income earned by the middle farm, was $96,130, substantially higher than the average.  This indicates that the average was pulled down or skewed by large losses sustained by...

2009 Michigan Land Values and Leasing Rates
Provedor de dados: 31
Autores: Wittenberg,   Eric; Harsh,   Stephen B.
Land is a natural resource that is valued for many reasons. Farmers utilize land to earn their livelihood and as a store of wealth for future retirement. Potential rural residents have increasingly sought open space for a home site and pursuit of a lifestyle. Developers seek financial opportunities to invest in and develop it for non-farm uses. Recreational needs such as hunting are often met through use of land. For some, land is viewed as an investment and a hedge against inflation. This myriad of demands for land combined with its fixed supply continually alters its market price, which is a monetary measure of its perceived value.

Provedor de dados: 31
Autores: Wittenberg,   Eric; Harsh,   Stephen B.
This report summarizes the 2010 financial and production records of 99 Michigan cash grain farms. To be included, the farms must have produced at least 50 percent of gross cash farm income from one or a combination of these items: corn, soybeans, wheat, navy beans, oats, sugar beets and other small grains. The records came from Michigan State University’s TelFarm project and Farm Credit Service of Michigan. The values were pooled into averages for reporting purposes. Farm records were included if a farm financial analysis had completed 2010 data including beginning and ending balance sheets and a statement of income and expenses. The data was checked to verify that cash discrepancy was less than 10% of gross cash inflow and that debt discrepancy was less...

2010 Michigan Land Values and Leasing Rates
Provedor de dados: 31
Autores: Wittenberg,   Eric; Harsh,   Stephen B.
Land is a natural resource that is valued for many reasons. Farmers utilize land to earn their livelihood and as a store of wealth for future retirement. Potential rural residents have increasingly sought open space for a home site and pursuit of a lifestyle. Developers seek financial opportunities to invest in and develop it for non-farm uses. Recreational needs such as hunting are often met through use of land. For some, land is viewed as an investment and a hedge against inflation. This myriad of demands for land combined with its fixed supply continually alters its market price, which is a monetary measure of its perceived value.

2010 North Dakota Agricultural Outlook: Representative Farms, 2010-2019
Provedor de dados: 31
Autores: Taylor,   Richard D.; Koo,   Won W.; Swenson,   Andrew L.
Net farm income for most representative farms in 2019 is projected to be lower than in 2009.  Low-profit farms, which comprise 20% of the farms in the study, may not have financial resiliency to survive without off-farm income.  Commodity prices are expected to increase slowly from current levels. Commodity yields are projected to increase at historical trend-line rates and production expenses are expected to return to normal growth rates. Debt-to-asset ratios for all farms except for the low profit farm will decrease slightly throughout the forecast period.  Debt-to-asset ratios for the low-profit farms are expected to increase to about 0.70.

2010 Outlook for the U.S. and World Corn and Soybean Industries, 2009-2019
Provedor de dados: 31
Autores: Taylor,   Richard D.; Koo,   Won W.
This report evaluates the United States and world corn and soybean markets for the 2009-2019 time period using the Global Corn and Soybean Policy Simulation Model. This analysis is based on a series of assumptions about general economic conditions, agricultural policies, weather conditions, and technological change. The major influence in the corn market will be U.S. corn based ethanol production. If the production of corn based ethanol remains strong, corn prices will likely remain strong. However, if the U.S. Federal government subsidies or mandates change, the world corn market could be negatively impacted. Under the current assumptions in the model, corn price is expected to remain in a range between $3.70 and $4.10 per bushel. The level of Chinese...

This report evaluates the U.S. and world sugar markets for 2009-2019 using the Global Sugar Policy Simulation Model. This analysis is based on assumptions about general economic conditions, agricultural policies, population growth, weather conditions, and technological changes. Both the U.S. and world sugar economies are predicted to remain stable over the next ten years in spite of the 2007-08 increase in world oil prices. That increase in oil price caused an increase in the conversion of sugar into ethanol in Brazil, while other exporting countries increased their production of sugar in response to higher sugar prices. Sugar prices remained strong in 2009 as the world’s economies recover slowly from the recession. World demand for sugar is expected to...

2(5H)-Furanone: a prospective strategy for biofouling-control in membrane biofilm bacteria by quorum sensing inhibition
Provedor de dados: 58
Autores: Ponnusamy,Kannan; Paul,Diby; Kim,Young Sam; Kweon,Ji Hyang.
Biofouling of membranes demands costly periodic cleaning and membrane replacement. A sustainable and environmentally friendly solution for maintenance is not available and would be of great interest for many purposes including economical. As complex biofilm formation by environmental strains is the major cause of biofouling and biofilm formation in most cases are controlled by N-Acylhomoserine lactone (AHL)mediated Quorum Sensing (QS). An effort was made to understand the appropriateness of 2(5H)-furanone, to use against biofouling of membranes. QS inhibition activity by 2(5H)-furanone was studied using bioindicator strains and known AHLs of different acyl chain lengths. The biofilm inhibition was studied by growth analysis on polystyrene plate of...

2D vortex interaction in a non-uniform flow
Provedor de dados: 5
Autores: Perrot, Xavier; Carton, Xavier.
In a two-dimensional incompressible fluid, we study the interaction of two like-signed Rankine vortices embedded in a steady shear/strain flow. The numerical results of vortex evolutions are compared with the analytical results for point vortices. We show the existence of vortex equilibria, and of merger for initial distances larger than those without external flow. The evolutions depend on the initial orientation of the vortices in the external flow.

30 años después : una reflexión sobre los estudios rurales y agrarios en Ecuador (Debate Agrario-Rural)
Provedor de dados: 122
Autores: Chiriboga V., Manuel.
En la primera década del siglo XXI se está produciendo un nuevo impulso a los estudios rurales y agrarios en el Ecuador. Esta revitalización tiene como protagonistas a diversos núcleos académicos situados en universidades y ONGS (sic) con marcos conceptuales y enfoques analíticos, así como especializaciones disciplinarias que los aglutinan. Algunos enfoques son sociológicos, otros provenientes de la economía política y ciencia política; economía agraria y ecología. Los  temas abordados incluyen ecosistemas y manejo de recursos naturales, tenencia de la tierra, género, trabajo rural, comercio internacional. Es evidente un nuevo dinamismo,  todavía débil, pero sin embargo prometedor. Aunque hace falta mayor interdisciplinareidad y construir espacios de...

3-D slope stability analysis: A probability approach applied to the nice slope (SE France)
Provedor de dados: 5
Autores: Leynaud, Didier; Sultan, Nabil.
Recent geophysical and geotechnical data acquired on the Nice shelf to the east of the 1979 landslide source area, Suggest slow deformations processes which could lead to future catastrophic slope failure. According to these preliminary interpretations, it is of major interest to perform a slope stability evaluation to define the hazard and quantify the danger related to a probable instability on this slope. A probabilistic approach is proposed here using a modified version of the SAMU_3D model, a 3-D slope stability software recently developed by Sultan and others to account for complex geometry. The 3-D analysis is based on the upper bound theorem of plasticity developed by Chen and others. One of the main features of the original model is to allow...

The 3 Dimensional structure of a protein is an expedient for structure based drug design and identifying the conformational epitopes that are foremost for designing the vaccines. Chikungunya (CHIKV) is a heat sensitive RNA virus which causes a viral disease which is transmitted in humans by human-mosquito-human transmission. Disease mostly found in the tropic and subtropical countries mainly in South India and in few other Asian countries. The primary transmission agents of Chikungunya Virus are yellow fever mosquito (_Aedes aegypti_) and forest day mosquito (_Aedes albopictus_). The forest day mosquito bites during day time and hence day time mosquito bite is the main reason for transmission. The main distinctive of the disease is a fever along with an...

5-Bromo-2’-deoxyuridine induces visible morphological alteration in the DNA puffs of the anterior salivary gland region of Bradysia hygida (Diptera, Sciaridae)
Provedor de dados: 56
Autores: de Almeida,J.C.; Sauaia,H.; Viana,J.C.
5-Bromo-2’-deoxyuridine (BrdUrd) has long been known to interfere with cell differentiation. We found that treatment ofBradysia hygida larvae with BrdUrd during DNA puff anlage formation in the polytene chromosomes of the salivary gland S1 region noticeably affects anlage morphology. However, it does not affect subsequent metamorphosis to the adult stage. The chromatin of the chromosomal sites that would normally form DNA puffs remains very compact and DNA puff expansion does not occur with administration of 4 to 8 mM BrdUrd. Injection of BrdUrd at different ages provoked a gradient of compaction of the DNA puff chromatin, leading to the formation of very small to almost normal puffs. By immunodetection, we show that the analogue is preferentially...

The functional effect of the A&gt;G transition at position 2756 on the MTR gene (5-methyltetrahydrofolate-homocysteine methyltransferase), involved in folate metabolism, may be a risk factor for head and neck squamous cell carcinoma (HNSCC). The frequency of MTR A2756G (rs1805087) polymorphism was compared between HNSCC patients and individuals without history of neoplasias. The association of this polymorphism with clinical histopathological parameters was evaluated. A total of 705 individuals were included in the study. The polymerase chain reaction-restriction fragment length polymorphism technique was used to genotype the polymorphism. For statistical analysis, the chi-square test (univariate analysis) was used for comparisons between groups and...

A 2D-QSPR approach to predict blood-brain barrier penetration of drugs acting on the central nervous system
Provedor de dados: 60
Autores: Sá,Matheus Malta de; Pasqualoto,Kerly Fernanda Mesquita; Rangel-Yagui,Carlota de Oliveira.
Drugs acting on the central nervous system (CNS) have to cross the blood-brain barrier (BBB) in order to perform their pharmacological actions. Passive BBB diffusion can be partially expressed by the blood/brain partition coefficient (logBB). As the experimental evaluation of logBB is time and cost consuming, theoretical methods such as quantitative structure-property relationships (QSPR) can be useful to predict logBB values. In this study, a 2D-QSPR approach was applied to a set of 28 drugs acting on the CNS, using the logBB property as biological data. The best QSPR model [n = 21, r = 0.94 (r² = 0.88), s = 0.28, and Q² = 0.82] presented three molecular descriptors: calculated n-octanol/water partition coefficient (ClogP), polar surface area (PSA), and...

Provedor de dados: 5
Autores: Huret, Martin; Petitgas, Pierre; Struski, Caroline; Leger, Fabien; Sourisseau, Marc; Lazure, Pascal.
Overexploitation and climate change are increasingly causing unanticipated changes in marine ecosystems, such as higher variability in fish recruitment and shifts in species distribution, pressing for developing fisheries oceanography. In the meantime, operational oceanography rapidly progresses and its products become easy to access to a large community, among them fisheries scientists. Multiyear oceanographic reanalyses (hindcasts) were identified has a priority product by the ICES WG on Operational Oceanographic Products for Fisheries and Environment (WGOOFE). We performed a 37 years hindcast (1972-2008) run with a coupled physical-biogeochemical model (ECO-MARS3D) over the Bay of Biscay, using realistic meteorological and run-off forcing. We first...

A agricultura familiar em Portugal: rupturas e continuidades
Provedor de dados: 123
Autores: Carmo,Renato Miguel do.
Em Portugal, as ciências sociais têm estudado a agricultura familiar a partir de um modelo de interpretação dualista que acentua as diferenças inter-regionais, marginalizando, até certo ponto, o significado sociológico de algumas continuidades que se estabeleciam (e se estabelecem) entre as zonas do Norte e do Sul ou entre o Litoral e o Interior. O presente estudo pretende, assim, construir uma perspectiva diferente sobre as modalidades de agricultura familiar em Portugal, procurando identificar, num primeiro momento, uma série de proximidades sociológicas entre os diferentes modos de organização (tradicionais e modernos) das famílias agrícolas e, consequentemente, traçar os eixos para um modelo mais complexo na análise dessas mesmas modalidades.

A Bacterial Enzyme Catalyzing Double Reduction of a &amp;#x3b2;,&amp;#x3b4;-Diketo Ester with Unprecedented Stereoselectivity
Provedor de dados: 17
Autores: Xuri Wu; Nan Liu; Yunmian He; Yijun Chen.
Various ketoreductases exclusively participate in all common biological events, and they are a class of important biocatalysts for the production of chiral alcohols. While many types of ketoreductase have been extensively studied and their functions, properties and utilities have been well known, the capability of stereoselectively reducing two carbonyl groups in the same diketohexanoate ester molecule to form a dihydroxy product by a single ketoreductase has not been evidently characterized. Here we show that a unique and novel enzyme, diketoreductase, was cloned from Acinetobacter baylyi, heterogeneously expressed in _Escherichia coli_ and purified to homogeneity. The diketoreductase is up to 78% homologous to bacterial 3-hydroxyacyl coenzyme-A...

This study aims to analyze the agribusiness contribution to Brazil’s trade balance. A new classification of the agribusiness trade balance was proposed and used to analyze the aspects of the exported products –agricultural products, products of animal origin, industrialized foods and imported inputs – represented by fertilizers. Imports and exports vector autoregression models were used to explain the behavior of these variables. An increase of 1% in the attractiveness – product of the exchange rate by the international prices – boosts immediately the exports of non processed agricultural products by 1.71%, stabilizing at 2% after some trimesters. The attractiveness explains 60 to 74% of the forecast error variances of these exportats. It is noted that an...

A helyzetfelmérés eredményeként megállapítható, hogy a magyar baromfi ágazat legfőbb problémája a nemzetközi versenyképesség romlása. Ennek számos következménye lehet, ami közvetlenül vagy közvetve érinti a fenntarthatóság három pillérét, a gazdasági, társadalmi és természeti tényezőket. Az elemzésben feltárt problémák ok-okozati kapcsolataiból egyértelműen kiderül, hogy mindezt az ágazat hazai és nemzetközi piaci kiszolgáltatottságának növekedése, valamint az ágazatban tapasztalható objektív versenyhátrányok megléte okozta. Ez utóbbi a versenytársakhoz képest tartósan alacsony jövedelmezőségnek, a technológiai színvonalban tapasztalható lemaradásnak, a korszerű tudás, illetve az ágazati stratégia hiányának tulajdonítható.

A BAYESIAN ALTERNATIVE TO GENERALIZED CROSS ENTROPY SOLUTIONS FOR UNDERDETERMINED ECONOMETRIC MODELS
Provedor de dados: 31
Autores: Heckelei,   Thomas; Mittelhammer,   Ronald C.; Jansson,   Torbjorn.
This paper presents a Bayesian alternative to Generalized Maximum Entropy (GME) and Generalized Cross Entropy (GCE) methods for deriving solutions to econometric models represented by underdetermined systems of equations. For certain types of econometric model specifications, the Bayesian approach provides fully equivalent results to GME-GCE techniques. However, in its general form, the proposed Bayesian methodology allows a more direct and straightforwardly interpretable formulation of available prior information and can reduce significantly the computational effort involved in finding solutions. The technique can be adapted to provide solutions in situations characterized by either informative or uninformative prior information.

A Bayesian analysis of the parasitic ecology in Jenynsia multidentata(Pisces: Anablepidae)
Provedor de dados: 76
Autores: Montes,Martin M.; Martorelli,Sergio R.
ABSTRACT Jenynsia multidentata Jenyns, 1842 (one-sided livebearers) are euryhaline viviparous fish of small size, used in the laboratory experiment, important as resource for biological control of mosquito’s larva and a key species to recover eutrophic lakes. Works have been published dealing with parasite biodiversity of this host, but little has been studied about the parasite community ecology. From early 2009 to ends of 2010 specimens of J. multidentata were collected from two places, the Salado Relief Channel (S.R.C.) on Samborombón Bay and the Sauce Chico River near to the city of Bahia Blanca (B.B.). All fish were sexed, measured and grouped into sizes/age classes. The fishes from both sites harbored 16 parasitic species: nine digenean, one...

Understanding the specific relationships between ecological and socioeconomic conditions and marine tenure is likely to contribute to successful functioning of self-governance institutions for common-pool resources. Complex interrelationships of factors influencing fishing activities of coastal communities and implementation of customary marine tenure over their waters can be represented in a Bayesian belief network model. We developed a Bayesian belief network model that includes the links between factors for fishing communities in the Kei Islands in Indonesia, based on indepth local surveys. Our results showed that the cumulative impacts of multiple factors on key social, economic, and environmental outcomes can be much larger than the impact from a...

Provedor de dados: 31
Autores: Harvey,   Sallyann; Fisher,   Bill; Larson,   Kristoffer; Malcolm,   Bill.
The Queensland Fruit Fly (QFF) — Bactrocera tryoni — poses a significant threat to horticultural production in Victoria causing losses of fruit and jeopardising access to interstate and international markets. The Victorian Government implements and largely funds an area freedom program to manage QFF. Concern about the record number of outbreaks in 2007-08 and the escalating costs of maintaining the current management regime, led the Victorian Department of Primary Industries to review the program to identify improved strategies for managing QFF. As part of this work, a benefit cost analysis (BCA) of alternative strategies has been conducted. While the BCA method is well established, in general few studies are publicly available for area freedom programs....

Plant growth is an essential ecological process, integrating across scales from physiology to community dynamics. Predicting the growth of plants is essential to understand a wide range of ecological issues, including competition, plant-herbivore interactions and ecosystem functioning.&amp;#xd;&amp;#xa;A challenge in modeling plant growth is that growth rates almost universally decrease with increasing size, for a variety of reasons. Traditional analyses of growth are hampered by the need to remain within the structures of linear models, which handle this slowing poorly. We demonstrate the implementation of a variety of non-linear models that are more appropriate for modeling plant growth than are the traditional, linear,...

A Binomial Tree Approach to Valuing Fixed Rotation Forests and Flexible Rotation Forests Under a Mean Reverting Timber Price Process
Provedor de dados: 31
Autores: Tee,   James; Scarpa,   Riccardo; Marsh,   Dan; Guthrie,   Graeme.
NPV and LEV are established and common approaches to valuing single rotation and infinite rotation forests respectively, when the rotation age is fixed in advanced. More recently, Real Options approaches have been employed to value single and infinite rotation forests with a flexible harvest age. Under a stochastic timber price process, it has been shown that the valuation of a flexible rotation forest is equal or higher than that of a fixed rotation forest, because a flexible harvest regime delays the harvest if the timber price is not favourable, whereas a fixed harvest regime would proceed to harvest regardless of the price. Often, valuation of fixed and flexible rotation ages are compared using 2 different methods – NPV (or LEV) and Real Options. The...

Egyben a fafeldolgozást végző kis- és középüzemek (elsősorban asztalosipari vállalatok, vállalkozások) a hulladék hasznosításának egy újabb, jövedelemforrást biztosító megoldásaként alkalmazhatják a fahulladék brikettáló gépeket. A brikettgyártás elterjedésére hazánk mezőgazdasági és ipari adottságai kiválóak, így fontos, hogy éljenek az ebben rejlő lehetőségekkel, különösen olyan környezetben, mely megköveteli az ésszerű és hatékony energiagazdálkodást.             -              As a result of the fuel price changes that have already taken place and which can be expected in the future, this...

Several fleets with various fishing strategies operate as a mixed fishery in the Bay of Biscay. Among the main fleets, bottom trawlers target Norway lobster (Nephrops norvegicus) and, together with gillnetters, they also catch hake (Merluccius merluccius). Trawling leads to average-size catches that are below the minimum landing size (MLS); such catches are discarded since they cannot be sold. These discards result in negative impacts on stock renewal, as most of them do not survive. This also results in an economic loss for both bottom trawlers and gillnetters since these discards represent a future loss of rent. This study, based on the 2009 and 2010 selectivity experiments at sea, assesses the short- and long-term bio-economic impacts of four...

A bio-economic evaluation of the American Foulbrood (AFB) control program in Western Australia
Provedor de dados: 31
Autores: Ghose,   Ananda; Hawkins,   Chris.
American foulbrood (AFB) is considered the most significant brood disease of bees in Western Australia. The Department of Agriculture of Western Australia (DAWA) provides assistance to apiarists by way of quarantine and surveillance measures under the AFB control program. A bio-economic evaluation was considered necessary by the department for setting future policy direction. As a way forward, a number of risk analysis scenarios were simulated to estimate the future prevalence rate of AFB in the absence of the present program. This epidemiological investigation was complemented by an economic evaluation which identifies the extent of benefit that flows through to direct beneficiaries. The paper provides a comprehensive bio-economic analysis and suggests...

A bioeconomic model of a marine park
Provedor de dados: 31
Autores: Greenville,   Jared W.; MacAulay,   T. Gordon.
A spatial bioeconomic model of a fishery will be used to investigate the effect of creating a marine park in a heterogeneous environment. Focus will be placed on the relevant biological and economic conditions needed to provide a benefit to both fishers and conservationists alike. The fishing environment will be one of limited entry to better simulate the conditions which exist in many developed nations. Fishers will be assumed to operate across patched in which the fish stocks are linked via either sink-source or density dependant spatial relationships.

A Bio-economic Model of a Shrimp Hatchery in the Mekong River Delta of Vietnam
Provedor de dados: 31
Autores: Sinh,   L.X.; MacAulay,   T. Gordon; Brennan,   Donna C.
Shrimp culture areas and production of the Mekong Delta cover about 60 percent of the total shrimp areas and production of Vietnam. Especially, the Delta contributes about 80 percent of the total shrimp production for export. Rapid development of the shrimp industry is raising a number of serious problems that need to be solved. Shrimp seed supply (post larvae production) plays an essential role in the shrimp industry and it is one of the most important constraints to the development of the shrimp industry in the Delta. The focus of this study is aimed at obtaining an improvement in both the profit per day and post larvae production of the shrimp hatchery in the Mekong River Delta of Vietnam. A Monte Carlo simulation approach was applied to develop a...

A bioüzemanyag-gyártás nemzetközi összefüggései
Provedor de dados: 31
Autores: Popp,   Jozsef.
A dráguló olajár „felszínre hozta” a fosszilis energiahordozók környezetbarát energiahordozókkal való kiváltásának problémáját. Az olajkészletek korlátozottsága mellett a bizonytalan kitermelés és a folyamatosan növekvő árak a bioüzemanyagok felé irányítják a politikai döntéshozók és a befektetők figyelmét. Az olajimportőr országoknak a bioüzemanyag-gyártás nyersanyagainak hazai termelése lehetővé teszi importköltségeik visszafogását, az üvegházhatást okozó gázok kibocsátásának csökkentését, valamint a mezőgazdasági termelők jövedelem-színvonalának javítását. A bioüzemanyagok elterjedése ugyanakkor enyhíti a kapacitása határán dolgozó olajfinomító ipar üzemanyag-ellátási terheit is, ami jelentős mértékben hozzájárul(t) az üzemanyagárak emelkedéséhez.

Az egyre növekvő energiafelhasználás, világnépesség és éhezés olyan, több évtizede megoldatlan problémák, amelyeket a klímaváltozás és az ez által kialakult szélsőséges időjárási viszonyok tovább súlyosbítottak, a napjainkban tapasztalható gazdasági válság pedig még inkább megnehezítheti megoldásukat. A megújítható energiaforrások szerepének növelésében katalizátorszerepet betöltő Európai Unió már a 80-as évek elején megoldást keresett a túltermelés következtében felhalmozódott szántóföldi termékek felhasználására. Az idők során a támogatási rendszer is a non-food termelést helyezte egyre inkább előtérbe, majd a kialakított direktívák és piaci intézkedések előkészítették, és így biztosították az összefoglalóan biomasszának nevezett megújítható...

A tanulmány a családi gazdálkodók együttműködési hajlandóságát befolyásoló tényezőket vizsgálja – Békés megye egy tradicionálisan mezőgazdasági termelő térségében készült – kérdőíves felmérés és mélyinterjúk tapasztalataira alapozva. A gazdálkodói bizalom és az együttműködési hajlandóság összefüggését elemezve megállapítható, hogy az alacsony függőséget, egyben alacsony bizalmi szintet is igénylő (valójában csak tágabban annak értelmezhető) együttműködési formák (jellemzően a gépi bérszolgáltatás) elfogadottsága a jellemző. Ugyanakkor a fiatalabb generációknál az erősebb függelmi kapcsolatokkal jellemezhető (a hagyományos értelemben vett) együttműködések elfogadottsága nagyobb, amely az agrárgeneráció-váltás bekövetkeztével esélyt teremt az együttműködési...

Bovine herpesvirus 5 (BoHV-5), the agent of herpetic meningoencephalitis in cattle, is an important pathogen of cattle in South America and several efforts have been made to produce safer and more effective vaccines. In the present study, we investigated in rabbits the virulence of three recombinant viruses constructed from a neurovirulent Brazilian BoHV-5 strain (SV507/99). The recombinants are defective in glycoprotein E (BoHV-5gEΔ), thymidine kinase (BoHV-5TKΔ) and both proteins (BoHV-5gEΔTKΔ). Rabbits inoculated with the parental virus (N = 8) developed neurological disease and died or were euthanized in extremis between days 7 and 13 post-infection (pi). Infectivity was detected in several areas of their brains. Three of 8 rabbits inoculated with the...

A Brief Review on the History, Methods and Applications of Plastination
Provedor de dados: 77
Autores: Pashaei,Shahyar.
Plastination is a process of preservation of anatomical specimens by a delicate method of forced impregnation with curable polymers like silicone, epoxy or polyester resins with vast applications in medical fields of study. Plastination is a technique of tissue preservation developed by Dr. Gunther von Hagens in 1977. In this process, water and lipids in biological tissues are replaced by curable polymers (silicone, epoxy, polyester) which are hardened, resulting in dry, odorless and durable specimens. In this technique it is possible for us to treat every part of the body and tissues to preserve it for educational purposes. Nowadays there are new and vast varieties of applications for plastination in the educational and cultural areas. This invention has...

Megállapítható, hogy Magyarország Európa kukoricatermelésében jelentős szerepet játszik, annak ellenére is, hogy az 1980-as évek közepétől nem tart lépést a hazai termésátlagok növekedése az EU-15 tagállamának átlagával. A búza jelentősége kisebb, itt a leszakadás az 1990-es évek elején kezdődött. A termésát-lagok jelentősen ingadoznak. A termelés meghatározó régiói: Észak- és Dél-Alföld, Dél-Dunántúl. A fedezeti termésátlag évről évre növekedett. A vizsgált időszakban a búzát a fő régiókban támogatások nélkül is sikerült – jellemzően a 26 AK-nál jobb minőségű földeken – nyereségesen termelni.

A CAP fit for the 21st Century
Provedor de dados: 31
Autores: Buckwell,   Allan.
This paper first discusses the driving forces for further CAP reforms, it then outlines  three approaches for the post-2013 CAP which have been spelled out by certain interest groups.  The third section examines a little more closely the critical elements of reform which seem likely to form the core of the debate in the next few years. These considerations lead to the conclusion that, in contrast to the reform process of the 1992 – 2004 period when there emerged a broadly accepted vision of how the CAP had to evolve, there is, as yet, no such widely accepted vision for the next period. In this vacuum it seems possible that the reform debate may be dominated by three actions: to cut, redistribute and transform the Single Payments.  Interest groups who...

Autores: KADOHIRA, Mutsuyo; TAJIMA, Motoshi; 門平, 睦代.
The Betsukai town office implemented bovine viral diarrhea virus (BVDV) preventive activities (i.e., vaccination and surveillance) in 2006. Using bulk tank milk screening followed by individual blood tests using a Reverse Transcription-Polymerase Chain Reaction (RT-PCR) method, persistent infection (PI) cattle were detected and eliminated from the population. Based on data for PI cattle detected between 2006 and 2007, we conducted a case control study to find risk factors associated with the presence of PI cattle. Significantly associated farm level factors for increasing risk of producing PI cattle include; 1) no recent purchase of cattle (between 2004 and 2007) and 2) no prevention of people/animals entering the premises. This study suggests that not...

Several filamentous oomycete species of the genus Halophytophthora have recently been described from marine environments, mostly from subtropical and tropical ecosystems. During a survey of oomycetes from leaf litter of Spartina alterniflora in salt marshes of southeastern Georgia, isolates of four taxa were recovered that bore similarity to some members of Halophytophthora but were highly divergent from isolates of Halophytophthora s.str. based on a combined sequence analysis of two nuclear loci. In phylogenetic analyses, these isolates were placed basal to a monophyletic group comprised of Pythium of the Pythiaceae and the Peronosporaceae. Sequence and morphology of these taxa diverged from the type species Halophytophthora vesicula, which was placed...

The cytogenetic studies have special importance in the zoological research because by means of karyotype analysis they contribute to the identifi cation of different entities, facilitate the evaluation of the proximity or relationship degree among certain species and fi nally they contribute with fundamental data to the phylogenetic assessment (Schmid et al., 1985; Zampieri et al., 2004). The occurrence of polyploidy in different anuran families that appear as cryptic species highlights the importance of the cytogenetic study at the population level (Valetti et al., 2009).

This article outlines the efforts of a small NGO, the Mareeba Wetland Foundation, to conserve nature and conduct tourism at its Mareeba Tropical Savanna Wetland Reserve in northern Queensland. It provides background about the establishment of the reserve and its nature and draws on the results from a survey of visitors to this reserve. It provides a socio-economic profile of visitors, their frequency of visits to it and their knowledge of it prior to visiting. This knowledge is found, on the whole, to be poor. The way in which visitors decided to visit the reserve is also considered as are indicators of the economic surplus obtained from visits. Because for most visitors their visit was an experiential good, doubts are raised about the traditional method...

A Case Study of Fall versus Spring Calving for the Rocky Mountain West
Provedor de dados: 31
Autores: Strauch,   Brian A.; Peck,   Dannele E.; Held,   Larry J.
Feeder cattle prices are generally lower in the fall, when the volume of calves for sale is highest. Most ranches in the Rocky Mountains calve in March or April, which results in the sale of weaned calves in October, when feeder cattle prices tend to be lowest. This study was initiated with the idea that a rancher might improve profitability by switching to fall calving, which would enable them to sell calves in April at a higher price. In this study, fall calving generated both higher and less variable profit, but mainly because of cost savings.

A Case Study of Regulation in Zambia’s Cotton Sector.
Provedor de dados: 31
Autores: Tschirley,   David L.; Kabwe,   Stephen.
Cotton is an unquestioned success of Zambia’s turn towards a market economy. After privatization in late 1994, seed cotton production rose from 32,000 metric tons (mt) to about 180,000 mt a decade later (three-year averages centered on 1994 and 2005). The number of farmers involved in the sector grew similarly, yields trended upwards (though slowly), and the country dramatically improved the quality of its lint, becoming the outstanding performer  in Sub-Saharan Africa in this regard by the mid-2000s. Yet the sector has experienced two serious crashes since reform, both involving rampant credit default by farmers supported with seasonal input credit by ginning companies.

A Cautionary Note on Individual Transferable Quotas
Provedor de dados: 7
Autores: Sumaila, U. Rashid; UBC Fisheries Centre, University of British Columbia; r.sumaila@fisheries.ubc.ca.
Individual transferable quotas (ITQs) are a type of catch share system, which is a tool used by some governments to manage fisheries. Technical reasons for taking a rather cautious approach to the implementation of ITQs have been provided previously. In the current contribution, I first highlight the strengths and weaknesses of ITQs and then provide suggestions on how to design and implement these quotas to mitigate their weaknesses. ITQs need to be designed carefully as part of a broad ecosystem-based management scheme to meet the three generally accepted objectives of modern fisheries management: ecological, economic, and social sustainability.

A certificação orgânica como fator estratégico na governança das transações no mercado de alimentos
Provedor de dados: 31
Autores: Cesar,   Aldara da Silva; Batalha,   Mario Otavio; Pimenta,   Marcio Lopes.
Food consumers are, in general, concerned with acquiring healthy food which does not pose risks to their health. These preferences are directly related to the way the economic agents organize themselves inside the food sector. In this context, the organic products’ share in the food market is rising considerably, mainly because they consist not only of a healthier product, but also because they contribute positively to the environment. Nevertheless, these characteristics are not immediately observed by the consumers, which makes the certification process an essential mechanism not in the transaction process but also in gaining the confidence of several markets. This article lists some advantages and disadvantages of the certification process raised in the...

A choice experiment method to assess vegetables producers’ preferences for crop insurance
Provedor de dados: 31
Autores: Mercade,   Lluc; Gil,   Jose Maria; Kallas,   Zein; Serra,   Jordi.
Agricultural producers face many risks in their economic activity due to weather conditions, plant or animal diseases, price volatility, policy changes and so on. One of the management tools to deal with some of these risks is the crop insurance system. In Catalonia (North-East of Spain) farmers’ participation in crop insurance for vegetables is low. Only 5 percent of the vegetables area is insured, when in Spain, as a whole, this percentage is around 20 percent. Different reasons have been suggested to explain this low participation ratio such as low risk perception, risk diversification, insurance cost or crop damage assessment rules, among others. However, no systematic research has been undertaken to assess farmers’ preferences for crop insurance in...

Autores: Mazur,   Kasia; Bennett,   Jeffrey W.
The survey was designed to estimate environmental values suitable for integration into MOSAIC, a bio-economic model for catchment and farm level planning. Local residents, as well as distant rural and distant urban communities, were surveyed in three NSW catchments (Lachlan, Namoi and Hawkesbury-Nepean) using choice modelling (CM). The survey aimed to find out respondents’ attitudes about, and preferences for, potential natural resource management (NRM) improvements. In total, 3,997 responses were collected from seven different locations in NSW. Fourteen split samples were established to allow for testing of incentive compatibility in CM, the impact of respondent location on values held, and scale effects.   This research report describes the development...

A CHOICE-EXPERIMENT BASED ANALYSIS OF PROTECTION MOTIVATION THEORY: HEALTH RELATED BEHAVIOR OF CONSUMERS WITH CELIAC DISEASE
Provedor de dados: 31
Autores: Zhang,   Jing; Steiner,   Bodo E.
The underlying components of protection motivation theory (PMT; Rogers 1983) are explored through choice experiment-based analysis within a random utility framework, to account for some of the motivational, cognitive, and affective processes that likely affect celiacs’ propensity to use a novel health-risk reducing product. Those four groups of variables that are aimed to capture threat appraisal and coping appraisal processes as part of the standard PMT (Rogers 1975, 1983; Floyd et al. 2000) are found to contribute significantly to explaining the adaptive response of celiacs. Self-assessed vulnerability and perceived product efficacy form a most significant part of respondents’ threat appraisal process. Standard socio-demographic and lifestyle...

The main objective of the present study was to upgrade a clinical gamma camera to obtain high resolution tomographic images of small animal organs. The system is based on a clinical gamma camera to which we have adapted a special-purpose pinhole collimator and a device for positioning and rotating the target based on a computer-controlled step motor. We developed a software tool to reconstruct the target’s three-dimensional distribution of emission from a set of planar projections, based on the maximum likelihood algorithm. We present details on the hardware and software implementation. We imaged phantoms and heart and kidneys of rats. When using pinhole collimators, the spatial resolution and sensitivity of the imaging system depend on parameters such as...

A cognitive psychological approach of analyzing preference uncertainty in contingent valuation
Provedor de dados: 31
Autores: Akter,   Sonia; Bennett,   Jeffrey W.
The sources of preference uncertainty in contingent valuation (CV) studies have rarely been investigated from a theoretical standpoint. This paper proposes a holistic theoretical framework of preference uncertainty that combines microeconomic theory with the theories of cognitive psychology. Empirical testing of the proposed theoretical model was carried out in Australia in the context of a national ‘Carbon Pollution Reduction Scheme (CPRS)’ to be introduced in 2010. Two separate ordered probit models for a certainty score associated with CV ‘Yes’ and ‘No’ responses were estimated. The results of the estimated regression models provide evidence supporting the hypotheses drawn from the theoretical model.

A Cohort Approach for Predicting Future Eating Habits: The Case of At-Home Consumption of Fresh Fish and Meat in an Aging Japanese Society
Provedor de dados: 31
Autores: Mori,   Hiroshi; Clason,   Dennis L.
Due to a rapidly aging society, stagnating per capita income and rather stable prices, traditional economic analyses methods lost their power in the 1990s to predict future food product consumption in Japan. This study, in part, remedies this problem by projecting future consumption of selected products, using a cohort approach with economic factors tentatively set aside. Per capita consumption of individual household members by age was derived by incorporating family age composition into household data classified by age groups of household head (HH). Individual consumption estimates were decomposed into age, cohort and time effects, using the Nakamura's Bayesian cohort model. These effects were synthesized to predict per capita consumption in each...

A Collaborative Breeding Strategy for Organic Potatoes in the Netherlands
Provedor de dados: 21
Autores: Lammerts van Bueren, E.T.
The ability of the organic farmer’s agronomic toolbox to reduce the susceptibility of a potato crop to late blight is limited, certainly under the Dutch climatic conditions. Conventional breeding programs do not generate either a sufficient number nor appropriate types of resistant varieties for organic systems; and a separate breeding program for the limited area of organic potato production is simply not viable. Therefore, all concerned forces have joined together in an umbrella program called Bioimpuls for organic potato improvement.

Autores: Brandenburg, Alfio.
Este texto tem por objetivo problematizar a noção de mundo rural e analisar as condições de emergência de novos atores. A partir da ideia de colonização do rural, os personagens que reagem ao processo de racionalização unilateral da vida social e biológica são definidos como novos atores, na medida em que reconstroem relações com o ambiente social e natural. A ação de novos atores inscreve-se no contexto de um campo de disputa de linguagens ecossociais e de distintas ruralidades, construindo-se uma racionalidade que se contrapõe ao domínio da racionalidade instrumental: a racionalidade ambiental ou ecológica.

Autores: Pascale Gaudet.
Biocuration is a difficult mission: biological data is highly heterogeneous, and there are few areas where guidelines for data preservation and exchange exist. This has hampered the speed, quantity and diversity of data possible to capture. Hence, a major challenge for the biocuration community is to explore innovative ways to capture, represent and display information. It is also essential to increase the involvement of researchers, publishers and funding agencies in this process. I will discuss the work of the International Society for Biocuration to build a community of biocurators to achieve these goals.

Autores: Rouan, Mathias; Kerbiriou, Christian; Levrel, Harold; Etienne, M.
An interdisciplinary team has applied the multi-agent system formalism to study shrub encroachment in the Biosphere Reserve on the isle of Ouessant. The main goals were (1) to understand vegetation dynamics, and (2) to represent how main agents, or actors view the dynamics of natural resources in relation to their own living practices. The management strategies established for each type of stakeholders were formalised and the impact of these strategies on biodiversity was analyzed at various temporal and spatial scales. Following a short description of the model, three aspects of the modelling process are discussed in more detail: the use of the chough (Pyrrhocorax pyrrhocorax) population as a representative variable for the interactions between...

Autores: Hadjadji, Imene; Frehi, Hocine; Ayada, Lembarek; Abadie, Eric; Collos, Yves.
Environmental conditions ultimately leading to blooms of the toxic dinoflagellate Alexandrium catenella/tamarense were investigated at two Mediterranean sites (Annaba Bay, Algeria and Thau lagoon, France). Three years were examined in details: 1992 (a pre-Alexandrium period), 2002 (a year with the first bloom in Annaba) and 2010 (a year with a major bloom in Annaba). Most conditions were similar, but ammonium concentrations were much higher in Annaba (up to 100 μM) than in Thau (up to 10 μM). First records of A. catenella/tamarense were in 1995 for Thau and 2002 for Annaba, and coincided with soluble reactive phosphorus (SRP) decreasing below a concentration of about 1 μM. No other environmental variable could be related to those blooms. Thus, it is likely...

A Comparative Analysis of Production and Marketing of Bt Cotton and Hybrid Cotton in Saurashtra Region of Gujarat State
Provedor de dados: 31
Autores: Visawadia,   H.R.; Fadadu,   A.M.; Tarpara,   V.D.
The study has revealed that the total cost per hectare is higher in Bt cotton than hybrid cotton. The cost of seeds has been found higher in Bt cotton, whereas hybrid cotton growers incur more cost on insecticides/ pesticides. This shows the effectiveness of the new technology (Bt cotton) for insect resistance. The average total cost of production as well as the bulk line cost have been found lower in Bt cotton. This depicts a reduction in the unit cost of Bt cotton, which is the distinct advantage of the new technology. A higher yield of 29 per cent has been obtained by the Bt cotton farmers over the hybrid cotton growers. The study has identified the constraints in production, and marketing of Bt cotton in the area. Bt cotton has been found a superior...

Autores: Sankey,   Lee; Hayes,   Dermot J.; Clemens,   Roxanne.
This study compared and analyzed actual 1989 production costs for representative regional feedlots in the U.S. The results show that grain-surplus regions have lower total costs and poorer feeding efficiencies. The analysis suggests that Iowa has a comparative advantage in producing heavily marbled beef required by the Japanese market. Southwestern states have an advantage in producing leaner beef and stand to benefit if U.S. consumers develop a taste for Select-quality beef.

A comparative efficiency analysis of wheat farms using parametric and nonparametric methods
Provedor de dados: 31
Autores: Mo,   Lijia.
This study examined whether the efficiency measures were invariant to choice of parametric and nonparametric methods for a sample of 183 wheat farms. The efficiency measures from the deterministic parametric method were smaller than those from the deterministic method. There was a trade-off between scale efficiency and economic efficiency. In the deterministic nonparametric method, the economic efficiency, scale efficiency and overall efficiency results were invariant to the number of inputs or the dimensionality. Only allocative and pure technical efficiency measures depended on the dimensionality. This work illustrated the importance of holding curvature for the cost function in stochastic frontier results.

Autores: Zhao,   Xufu; Tisdell,   Clement A.
After providing information about the global importance of cotton as a textile and China’s and Australia’s contribution to global cotton production, this paper examines and compares trends in the time-series of cotton production of China and Australia for the period 1980-2007. In doing so, it takes account of changes in the area planted with cotton and its yield. Correlation estimates and decomposition analysis are used to determine the relative contribution to variations in the total output of cotton of changes in the total area planted with cotton and its yield in both countries. These relative contributions are found to be quite different for Australia and China. In addition, there is a comparative analysis of fluctuations in the production of cotton,...

Increased demand for certified organic products has led to  an increase in the number of certified organic farms in developing countries. Knowledge of farmer nutrient management practices on certified organic farms in developing countries is limited. Thus, the aim of this study was to investigate the impact of the adoption of certified organic agriculture on farm nutrient flows and nutrient budgets, and evaluate to which degree organic farms comply with organic principles relating to nutrient   management. The study is based on five case studies of different types of certified organic farming systems in Brazil, Egypt and China. Farm nutrient flows and nutrient budgets for nitrogen, phosphorous and potassium were created for each farm. Four of the five...

Autores: Loomis,   John B.; Bell, Paul; Cooney, Helen; Asmus, Cheryl.
We estimate adults’ willingness to pay (WTP) to reduce health risks to their own or other families’ infants to test for altruism. A conjoint analysis of adults paying for bottled water found marginal WTP for reduction in risk of shock, brain damage, and mortality in the cash treatment of $2, $3.70, and $9.43, respectively. In the hypothetical market these amounts were $14, $26, and $66, indicating substantial hypothetical bias, although not unexpected due to the topic of infant health. Statistical tests confirm a high degree of altruism in our WTP results, and altruism held even when real money was involved.

Experimental auction and discrete choice experiment are two popular value elicitation methods. Theoretically they should yield the same results but empirical results have been mixed (e.g., Lusk and Schroeder 2004, 2006; Corrigan et al. 2010.) This study uses both methods to determine consumers’ willingness to pay (WTP) for rice with improved insect control and for rice stored using Integrated Pest Management (IPM). This study investigates two potential reasons – anchoring and information – for why some studies have found apparent inconsistencies between auction and choice experiment results. Results indicate that consumers’ WTP derived in the auction and choice experiments are significantly different. Consumers’ average bids in the auction are higher than...

Food security—consistent access to enough food for an active, healthy life—is essential for health and good nutrition. The extent to which a nation’s population achieves food security is an indication of its material and social well-being. Differences in the prevalence of household level food insecurity between Canada and the United States are described at the national level and for selected economic and demographic subpopulations. Associations of food security with economic and demographic characteristics are examined in multivariate analyses that hold other characteristics constant. Comparable measures of household food security were calculated from the nationally representative Canadian Community Health Survey Cycle 2.2 (2004) and the U.S. Current...

Autores: Richardson,   Leslie; Loomis,   John B.; Champ,   Patricia A.
Wildfire seasons are becoming longer and more intense throughout the world, making it increasingly important to monetize the full damages caused by wildfires when analyzing various fire management policies. We estimate the economic costs of the health effects associated with exposure to wildfire smoke using a simple cost of illness approach and for the first time to our knowledge we estimate willingness-to-pay (WTP) for a decrease in symptom days from wildfire smoke using the contingent valuation method and the averting behavior method.

A Comparison of Parametric Approximation Techniques to Continuous-Time Stochastic Dynamic Programming Problems
Provedor de dados: 31
Autores: Kompas,   Tom; Chu,   Long.
We compare three parametric techniques to approximate Hamilton-Jacobi-Bellman equations via unidimensional and multidimensional problems. The linear programming technique is very efficient for unidimensional problems and offers a balance of speed and accuracy for multidimensional problems. A comparable projection technique is shown to be slow, but has stable accuracy, whereas a perturbation technique has the least accuracy although its speed suffers least from the curse of dimensionality. The linear programming technique is also shown to be suitable for problems in resource management, including applications to biosecurity and marine reserve design.

A comparison of the economic and environmental performances of conventional and organic farming: evidence from financial statements
Provedor de dados: 31
Autores: Argiles,   Josep M.; Brown,   Nestor Duch.
While conventional farming systems face serious problems of sustainability, organic agriculture is seen as a more environmentally friendly system since it favours renewable resources, recycles nutrients, uses the environment’s own systems for controlling pests and diseases, sustains ecosystems, protects soils, and reduces pollution. At the same time organic farming promotes animal welfare, the use of natural foodstuffs, product diversity and the avoidance of waste, among other practices. However, the future of organic agriculture will depend on its economic viability and on the determination shown by governments to protect these practices. This paper performs panel regressions with a sample of Catalan farms (Spain) to test the influence of organic farming...

A comparison of the effects of physical and chemical mutagens in sesame (Sesamum indicum L.)
Provedor de dados: 74
Autores: Begum,Tamina; Dasgupta,Tapash.
Three sesame genotypes (Rama, SI 1666 and IC 21706) were treated with physical (γ-rays: 200 Gy, 400 Gy or 600 Gy) or chemical (ethyl methane sulphonate, EMS: 0.5%, 1.0%, 1.5% or 2.0%) mutagens and their mutagenic effectiveness and efficiency were estimated in the M2 generation. The M3 generation was used to identify the most effective mutagen and dose for induction of mutations. The average effectiveness of EMS was much higher than γ-rays. The lowest dose of γ-rays (200 Gy) and the lowest concentration of EMS (0.5%) showed the highest mutagenic efficiency in all genotypes. Analysis of the M3 generation data based on parameters such as the variance ratio and the difference in residual variances derived from the model of Montalván and Ando indicated that...

Provedor de dados: 5
Autores: Institute for Environment and Sustainability (Joint Research Centre).
Chemical risk assessment always entails an evaluation of expected environmental concentrations of substances; these concentrations may be predicted using mathematical models or may be chosen on the basis of experimental observations and monitoring activities. The work discusses the usefulness and limitations in building compilations of published monitoring data by describing a feasibility study on polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-pdioxins and dibenzofurans (PCDD/Fs), for which observed concentration data were retrieved from scientific journal articles published between 2000 and 2009. These chemicals are typical POPs and are of constantly high concern for their potential adverse effects on human health and ecosystems. PCBs were...

A complementary strategy for the conservation of native forest tree species: retrieval and conservation of threatened ecotypes
Provedor de dados: 190
Autores: Shimizu, Jarbas Yukio.
Deforestation has become rampant in recent years in Brazil and has affected all biomes where manyspecies are threatened to extinction due to destruction natural habitats. Government initiatives to hinder thechain of destruction include two main lines of action: to establish conservation units (parks, reserves andothers); and programs to encourage plantation of native tree species for reclamation of degraded ecosystems, restoration of forests on permanent protection areas (riparian, and steep slope environments), and establishment of “legal reserves” (a mandatory forest reserve on at least 20% of the land area). Conservation units are effectivein conserving natural ecosystems. However, they are of limited value for the conservation of ecotypes, sincetheir...

A Consumer-oriented Study of the South African Beef Value Chain
Provedor de dados: 31
Autores: Labuschagne,   Anita; Louw,   Andre; Ndanga,   Leah Z.B.
The South African beef industry, like many other South African supply chains, is challenged by the increased complexity and demand brought about by globalization, increased volumes and competition, shortage of skilled staff and pressures to meet changing customer needs. The power has shifted from the supply side to the consumer. The consumer has been empowered by greater knowledge. Consumer needs are changing. A combination of these two facts implies that not only the retailer, but also the supply chain as a whole must make sure that it is aligned to deliver customer value, in order to ensure sustainable competitiveness and survival, manage risks and ensure acceptable returns. Competition today is based on competing supply chains. The focus of this study...

A continuous hockey stick stock-recruit model for estimating MSY reference points
Provedor de dados: 5
Autores: Mesnil, Benoit; Rochet, Marie-joelle.
With political commitment to restore stocks to levels where they can produce maximum sustainable yield (MSY), fisheries managers request evaluations of management plans that include options for an FMSY policy. The procedure to estimate FMSY with dynamic-pool, stock assessment models is well established for common stock-recruitment relationships (S-RR). In this paper, we extend this capacity to another S-RR, a piecewise function known as the hockey stick, which is frequently assumed when the data do not support more elaborate functions. However, the hockey stick is not continuous, which makes it problematic for this application, where differentiable functions are required. The bent-hyperbola model proves to be an adequate continuous equivalent to the hockey...

A cooperative and specific DNA-binding mode of HIV-1 integrase depends on the nature of the metallic cofactor and involves the zinc-containing N-terminal domain
Provedor de dados: 5
Autores: Carayon, Kevin; Leh, Herve; Henry, Etienne; Simon, Francoise; Mouscadet, Jean-francois; Deprez, Eric.
HIV-1 integrase catalyzes the insertion of the viral genome into chromosomal DNA. We characterized the structural determinants of the 3'-processing reaction specificity-the first reaction of the integration process-at the DNA-binding level. We found that the integrase N-terminal domain, containing a pseudo zinc-finger motif, plays a key role, at least indirectly, in the formation of specific integrase-DNA contacts. This motif mediates a cooperative DNA binding of integrase that occurs only with the cognate/viral DNA sequence and the physiologically relevant Mg(2+) cofactor. The DNA-binding was essentially non-cooperative with Mn(2+) or using non-specific/random sequences, regardless of the metallic cofactor. 2,2'-Dithiobisbenzamide-1 induced zinc ejection...

This work shows that the political and legal resources available to citrus farmers have become as strategic as financial, technological and organizational resources. The study presents an analysis of the Brazilian citrus business governance, which is defined by the use of different strategies among citrus farmers and processing plants: the citrus farmers and their main association use political resources, while some big juice processing plants resort to legal resources. This opposition represents a new obstacle to the achievement of positive results by citrus farmers in the current power network. Court orders demonstrate that orange supply contracts have become a fundamental empowering instrument in the sector, leading to strategic gains for the juice...

A DEB model to predict accumulation and detoxification of paralytic shellfish toxins by the Japanese Oyster (Crassostrea gigas)
Provedor de dados: 5
Autores: Pousse, Emilien; Jean, Frédéric; Alunno-bruscia, Marianne; Flye Sainte Marie, Jonathan.
France being the largest consumer of oysters in Europe, oyster farming is deeply rooted in French heritage. The Japanese oyster (Crassostrea gigas) is the oyster species the most exploited in France, and in the world. Due to filter-feeding, these bivalves are sensitive to toxic algal blooms. Although not always lethal, toxic algae can affect oyster physiology and make it unfit for human consumption. Phytoplankton toxins can be classified in several groups: amnesic, neurotoxic, diarrhetic and paralytic. For the latter group, saxitoxins are synthesized by the microalgae of genus Alexandrium that can accumulate bivalve tissues.  In recent years, number of studies have been performed on the interactions between C. gigas and saxitoxins. In order to better...

A decline in pollinator dependent vegetable crop productivity in India indicates pollination limitation and consequent agro-economic crises.
Provedor de dados: 17
Autores: Parthiba Basu; Ritam Bhattacharya; Pietro Ianetta.
Approximately 70% of the tropical crop species depend on pollinators for optimum yields (Roubik, 1995, Klein 2007). The economic value of such pollinated crops to India is $726 million and India is the world&amp;#x27;s second largest vegetable producer (Sidhu, 2005). This status has been underpinned by large-scale changes in land-use and pesticide dependency (Fazal, 2000; Shaw &amp;#x26; Satish, 2007). A method (c.f. Aizen et al. 2008) that partitions crops into categories depending on their relative pollinator dependence (Index of pollinator dependence, DI) was applied to analysis of vegetable yields for India over 45 years (1963-2008) using FAO data. This has revealed that since 1993, relative yields of crop production has either flattened or declined,...

A Derbyshire screwstone (Mississippian) from the beach at Overstrand, Norfolk, eastern England
Provedor de dados: 16
Autores: Donovan, S.K.
A distinctive chert erratic pebble found on the beach at Overstrand, north Norfolk, eastern England, is a Derbyshire screwstone. Such cherts are typical of the Mississippian (Lower Carboniferous) limestones of the southern Pennines (White Peak), over 200 km to the northwest. It was most probably transported by fluvial or glacial action during the Pleistocene and was recently disinterred by coastal erosion. The most diagnostic feature of screwstone cherts are the included mouldic crinoid ossicles, particularly columnals. Columnals of the monobathrid camerate crinoid Megistocrinus? globosus? (Phillips) are described from this screwstone; these have a circular outline, central pentagonal lumen and a raised perilumen. The uncertainty of the identification is...

A Description of Voluntary Policy Methods for Natural Resource Management
Provedor de dados: 31
Autores: Parminter,   Terry G.
The voluntary policies being used by local authorities to deliver Resource Management Act outcomes are considered nonstatutory policy methods under the Act, which does not define them or describe how they might be selected and implemented. One economist has been able to list over 50 different economic methods. A similar list has not been available for policy agents interested in drawing upon the rich and extensive experience of people in other disciplines such as agricultural extension and social marketing. Applied literature in a number of social science disciplines has been used in this paper to put such a list together. The author describes possible voluntary policy methods including those associated with adult learning, communication, networking and...

A developmental approach to homology and brain evolution
Provedor de dados: 97
Autores: ABOITIZ,FRANCISCO.
Although homology is central to evolutionary interpretations, establishing it has become a highly disputed issue in some instances. Here I argüe for a developmental understanding of evolution, where modifications of the developmental programs are a key source of evolutionary novelty. Although this perspective is not new, in comparative neurobiology it has remained controversial. Specifically, the evolutionary origin of the mammalian neocortex has been a particularly debated point. I propose a perspective that could help reconcile a long standing controversy: either the mammalian neocortex corresponds as a whole to the dorsal hemisphere of reptiles and birds, or alternatively its lateral aspect corresponds to the lateral cerebral hemisphere and is partly...

A diffusion model for the adoption of agricultural innovations in structured adopting populations
Provedor de dados: 31
Autores: McRoberts,   Neil; Franke,   A.C.
We introduce a new model for examining the dynamics of uptake of technological innovations in agricultural systems, using the adoption of zero-till wheat in the rice-wheat system in Haryana state, India, as a case study. A new equation is derived which describes the dynamics of adoption over time and takes into account the effect of aggregation (e.g. on a spatial and/or cultural basis) in the adopting population on the rate of adoption. The model extends previous phenomenological models by removing the assumption of homogeneity in the non-adopting fraction of the population. We show how factors affecting the per capita rate of adoption can be captured using cognitive mapping and simulate the dynamics of the adoption process.

The eastern English Channel, which connects the Atlantic Ocean to the North Sea through the Dover Strait, is an area where numerous and often conflicting human activities take place. A cross-border multidisciplinary project called CHARM was initiated to provide knowledge and tools for planners and decision-makers to durably manage the shared marine living resources. One such tool was an atlas of fish spatial distributions and modelled habitats, which was used here to investigate ontogenic and seasonal shifts in fish spatial distribution and habitat through a case-study, the dab Limanda limanda. Survey data for several life-history stages (eggs, larvae, coastal nurseries, &lt; and &gt; 1 year old) and seasons were used to map spatial patterns (using...

Autores: Massuquetti,Angélica.
Este artigo investiga o processo de modernização agrícola na França com base na interpretação de economistas, sociólogos e cientistas políticos, envolvendo especialmente o debate da economia e da sociologia rural contemporâneas. O objetivo é compreender a sua dinâmica pelo cruzamento entre diferentes áreas do conhecimento, visando refletir acerca de um modelo interpretativo para a análise da especificidade do processo brasileiro de modernização agrícola. O mundo rural não se transformou unicamente no âmbito econômico, por meio da adoção de inovações e de novas inserções no mercado, mas houve também a construção de novas identidades políticas e sociais no campo.

A dinâmica da área, do rendimento e dos preços sobre o valor da produção do feijão e da soja no Rio Grande do Sul e a dependência temporal entre esses componentes
Provedor de dados: 65
Autores: Bini,Dienice Ana; Canever,Mario Duarte.
Objetiva-se neste artigo avaliar o crescimento do valor da produção (VP) do feijão e da soja no Rio Grande do Sul (RS), baseado no comportamento de seus determinantes área, rendimento e preço. Também se pretende determinar como choques nestes componentes transmitem-se de uma safra para outra no VP. Utilizaram-se dados de área, rendimento e preço do feijão preto e da soja no RS de 1977 até 2010. A metodologia shift-share permitiu decompor a importância de cada item sobre a variação do valor da produção. O ferramental de séries temporais permitiu obter o efeito de um choque em uma variável, ceteris paribus, sobre as demais. No curto prazo, o rendimento é o principal responsável pela variação do VP. Entretanto, no longo prazo, a queda dos preços reais de...

Autores: ARAUJO, L. S. de; GREGO, C. R.; BOLFE, E. L.; OSHIRO, O. T.
No contexto do histórico de uso e ocupação das terras do Estado de São Paulo, que resultou na perda quase total de suas florestas originais e degradação dos remanescentes, as atividades agropecuárias são identificadas como potenciais condicionantes pela crescente expansão ocorrida nas últimas décadas. Por outro lado, levantamentos atuais, como o realizado pelo Instituto Florestal de São Paulo, demonstram um incremento na área mapeada como vegetação nativa do Estado (ZORZETTO, 2010), com curva ascendente similar às formulações recentes da Teoria da Transição Florestal (RUDEL, 1998; RUDEL et al., 2005). De acordo com essa Teoria, os estoques florestais mudam de modo previsível, com o decréscimo da taxa de desflorestamento e aumento da taxa de regeneração...

A Discrete State Model for Kinesin-1 with Rate Constants Modulated by Neck Linker Tension
Provedor de dados: 17
Autores: Steven J. Koch; Lawrence J. Herskowitz.
Kinesin-1 is a homodimeric molecular motor protein that uses ATP and a hand-over-hand motion to transport cargo along microtubules. How kinesin converts chemical energy into directed motion is a question that has been actively studied since its discovery. Even at the most coarse-grained level of chemical kinetics, understanding is still lacking. Minimal kinetic models are often developed to both explain kinesin&amp;#x2019;s hand-over-hand forward-stepping behavior and to infer important kinetic rate constants from experimental data. These minimal models are often limited to a handful of two-headed states on a core cycle and have been essential for the current level of understanding. However, it is not always clear how to evolve these core-cycle models to...

Autores: Amaral,Dany S; Venzon,Madelaine; Pallini,Angelo; Lima,Paulo C; DeSouza,Og.
The effects of increasing plant diversity on the population of the coffee leaf-miner Leucoptera coffeella (Guérin-Mèneville) were investigated in two organic coffee production systems. One system consisted of coffee intercropped with banana trees (shaded system) and the other one of coffee intercropped with pigeon pea (unshaded system). The increase in plant diversity on both systems was achieved via introduction of green manures such a perennial pea nut, sunn hemp and Brazilian lucerne. The population of L. coffeella, predation and parasitism of L. coffeella mines were biweekly evaluated during eight months. The increase in plant diversity on both systems did not affect the attack of L. coffeella on coffee leaves and the mine parasitism rate. However,...

A DNA enzyme targeting Egr-1 inhibits rat vascular smooth muscle cell proliferation by down-regulation of cyclin D1 and TGF-β1
Provedor de dados: 56
Autores: Wu,Y.; Han,W.; Liu,G.-N.
We have demonstrated that a synthetic DNA enzyme targeting early growth response factor-1 (Egr-1) can inhibit neointimal hyperplasia following vascular injury. However, the detailed mechanism of this inhibition is not known. Thus, the objective of the present study was to further investigate potential inhibitory mechanisms. Catalytic DNA (ED5) and scrambled control DNA enzyme (ED5SCR) were synthesized and transfected into primary cultures of rat vascular smooth muscle cells (VSMCs). VSMC proliferation and DNA synthesis were analyzed by the MTT method and BrdU staining, respectively. Egr-1, TGF-β1, p53, p21, Bax, and cyclin D1 expression was detected by RT-PCR and Western blot. Apoptosis and cell cycle assays were performed by FACS. Green fluorescence could...

A Dual Approach to Estimation With Constant Prices
Provedor de dados: 31
Autores: Paris,   Quirino; Caputo,   Michael R.
In a recent paper, Mundlak assumes that the price-taking, risk-neutral and profit-maximizing entrepreneur makes his decisions on the basis of a planning model that maximizes expected profit using expected prices. In the same paper, the author asserts that when there is no sample price variation across competitive firms, it is impossible to estimate the supply and factor demand functions from cross-section data using a dual approach. In a famous paper, titled “To Dual or not to Dual,” Pope asserted a similar opinion. This paper shows that, using Mundlak’s assumption about planning decisions based upon expected profit, it is possible to use a dual estimator to estimate supply and factor demand functions. This objective is achieved by using Mundlak’s...

A Dynamic Characterization of Efficiency
Provedor de dados: 31
Autores: Stefanou,   Spiro E.
The definition and measurement of dynamic economic performance has been addressed obliquely in the literature with the notions of scope economies and capacity utilization measures, but little work has focused on develop the static theory analogs of efficiency measures into the dynamic context. This paper is an attempt to identify some of the conceptual and methodological issues to be addressed. A model allowing for dynamic production decisions in the face of inefficiency is presented to illustrate some of the issues and the extensions necessary to identify truly dynamic performance measures.

A Dynamic Decision Support System for Farm Water Management in Surface Irrigation: Model Development and Application
Provedor de dados: 117
Autores: Flores,Carlos I.; Holzapfel,Eduardo A.; Lagos,Octavio.
An online dynamic decision support system (DDSS) was developed, to support the farm water management in surface irrigation. The online DDSS was based on the formulation and integration of three components: a dynamic-relational data base, an administrator model, and a graphical user interface. The DDSS allows routines of actualization, edition and addition of online data, providing information in real time. The online DDSS was applied in an orange orchard (Citrus sinensis L. Osbeck) cv. Valencia Late under furrow irrigation. The results pointed out that the time irrigation cutoff was the main significant management factor, to decrease the hazard of leaching, superficial runoff and percolation. Applying the results obtained with the DDSS, furrow irrigation...

A dynamic dual model under state-contingent production uncertainty
Provedor de dados: 31
Autores: Serra,   Teresa; Stefanou,   Spiro E.; Oude Lansink,   Alfons G.J.M.
In this paper we assess how production costs and capital accumulation patterns in agriculture have evolved over time, by paying special attention to the influence of risk. A dynamic state-contingent cost minimization approach is applied to assess production decisions in US agriculture over the last century. Results suggest the relevance of allowing for the stochastic nature of the production function which permits to capture both the differences in the costs of producing under different states of nature, the differences in the evolution of these costs over time, as well as the differential impacts of different states of nature on investment decisions.

Autores: Beach,   Robert H.; Birur,   Dileep K.; Davis,   Lauren M.; Ross,   Martin T.
With the rising global interest in energy security and climate change mitigation, biofuels have gained the prominent attention of researchers and policy makers. The U.S. has emerged as the leading producer of biofuels and is aiming for achieving a target of 36 billion gallons of renewable fuels by 2022 under its updated renewable fuels standard (RFS2) policy. In this paper, we study the longer-term global implications of large-scale renewable fuels production in the U.S. We utilize the GTAP v7.1 data base and introduce a detailed breakdown of agricultural crops, first and second generation biofuels and by-products. We update this fully disaggregated data base to reflect the 2010 global economy, based on secondary data for the sectors and regions included....

A Dynamic Model of Mesh Size Regulatory Compliance
Provedor de dados: 31
Autores: Akpalu,   Wisdom.
This paper employs a dynamic model for crimes that involve time and punishment to analyze the use of a net with illegal mesh size in a management regime where each community claims territorial use right over a fishery but has a discount rate that may differ from the social discount rate. The equilibrium stock and harvest levels are found to be much lower if the regulation is violated. Moreover, the optimal penalty for violation must be decreasing in the shadow cost of taking the risk to fish illegally, and increasing the risk of punishment increases the equilibrium stock level.

A dynamical model of genetic networks describes cell differentiation
Provedor de dados: 17
Autores: Roberto Serra; Villani Marco; Alessia Barbieri.
Cell differentiation is a complex phenomenon whereby a stem cell becomes progressively more specialized and eventually gives rise to a specific cell type. Differentiation can be either stochastic or, when appropriate signals are present, it can be driven to take a specific route. Induced pluripotency has also been recently obtained by overexpressing some genes in a differentiated cell. Here we show that a stochastic dynamical model of genetic networks can satisfactorily describe all these important features of differentiation, and others. The model is based on the emergent properties of generic genetic networks, it does not refer to specific control circuits and it can therefore hold for a wide class of lineages. The model points to a peculiar role of...

Resumo: O objetivo deste trabalho foi analisar a eficiência técnica dos produtores de leite no Uruguai, com base nos dados do Censo Geral Agropecuário, correspondente ao exercício produtivo 2010/2011. Empregou-se a abordagem da análise de fronteiras estocásticas, obtendo-se a medida da eficiência técnica média, assim como de cada estabelecimento. Os resultados mostraram que os produtores leiteiros do Uruguai operam, em média, aos 79,9% da sua capacidade, o que mostra que muitos deles poderiam ainda melhorar seus rendimentos com a tecnologia disponível. Além disso, os resultados mostram que a assistência técnica e a utilização de silos reduzem possíveis ineficiências.

A Euro-Mediterranean deal in agro-food and fisheries trade: Long run impacts in Greece
Provedor de dados: 31
Autores: Kitou,   Elisavet; Philippidis,   George.
We employ a heavily modified ‘agricultural’ variant of the GTAP model and a realistic baseline scenario to assess the impact on the Greek economy from a hypothetical ‘hub and spoke’ and a ‘FTA’ EUMED agro-food and fisheries trade agreement. Long run estimates show that Greek agro-food and fisheries sectors are not seriously affected, where surprisingly, trade diversionary losses to Greece from the FTA scenario are minor given minimal south-south trade links between Mediterranean Partner Countries (MPC). Further research shows that under complete CAP decoupling, notable additional welfare gains for MPC are realised, whilst Greece stands to lose approximately €300 million.

International trade has acquired increasing importance for the Brazilian economy, especially for agribusiness. In this way, understanding other countries policies that affects international trade and its impacts in this country is equally important. The European Union (EU) is one of the most important Brazilian trade partners and it is known by strong interference on its agricultural sector. The recent European enlargement and the last Common Agricultural Policy (CAP) Reform have been studied at different regions of the World but there is a lack of knowledge regarding the impacts of this on Brazilian rural sectors. This paper aims to assess the impacts of the 2004 EU enlargement on Brazilian agribusiness using the general equilibrium model Global Trade...

Agricultural insurance is considered to be an effective to manage rural risks. Surprisingly, its adoption by farmers is very limited all over the world. An outstanding exception is the United States of America, country in which this instrument has achieved remarkable success. Nevertheless, the process of diffusion of agricultural insurance in the USA was slow and expensive. It has also required significant government intervention through a variety of complementary actions. In this context, countries willing to introduce this instrument among other agricultural policy tools, as it seems the case of Brazil, should proceed with caution. Agricultural insurance success has important pre-requisites and its general diffusion may amplify its problems. The analysis...

A fajtacsoport szerepe az alföldi juhászatok eredményeiben

Autores: Monori,   Istvan.
A vizsgált juhászatok a hazai átlagtól eltérő fajtaösszetételűek és nagyobb nyájméretűek, de a nagyobb állományokhoz korszerűtlen technológia társul, ami korlátozza a potenciális hozamok elérését. A költségek szerkezetéből kitűnik, hogy a takarmányköltségek mellett a személyi jellegű költségek aránya igen magas a vizsgált gazdaságok állománykoncentrációja ellenére is, ami utal az évtizedek óta elavult tartástechnológiára is. A fajtacsoportonkénti bevételekben szembetűnő a tejelő juhászatok kimagasló teljesítménye, míg a húshasznú és keresztezett fajtáknál ez alig haladja meg a merinó fajtacsoportét.

A falsa dicotomia entre a preservação da vegetação natural e a produção agropecuária

Este artigo mostra através da análise de dados censitários sobre uso da terra no Brasil que a possível dicotomia entre a preservação da vegetação natural e a produção de alimentos na realidade não existe. Demonstramos que o Brasil já tem uma área desprovida de vegetação natural suficientemente grande para acomodar a expansão da produção agrícola. Demonstramos também que a maior expansão se dá nas áreas ocupadas pelas chamadas culturas de exportação - soja e cana-de-açúcar - e não propriamente nas áreas ocupadas por arroz, feijão e mandioca, que são consumidos de forma direta pelo mercado nacional. Pelo contrário, a área colhida de arroz e feijão tem inclusive decrescido nas últimas décadas, enquanto a área colhida de mandioca encontra-se praticamente...

A farm level assessment of the profitability of Entry Level Scheme participation in the Lincolnshire Wolds
Provedor de dados: 31
Autores: Harrison,   George R.; Jones,   James V.H.
The paper builds on the results of previous studies investigating whether farmers profit by participation in the Entry Level Scheme (ELS). Standard payment levels (derived from points) under ELS are fixed at rates that are expected only to compensate farmers for income foregone and costs incurred. There is no profit element as such. There is therefore no reason to expect participation to be profitable. However farm level examination of the income foregone and costs incurred in previous studies based in other parts of England have shown that this can be achieved. The study is based in the Lincolnshire Wolds, an area dominated by arable farming but with topography and associated natural features that offer some variety in the mix of farming and the measures...

A fenntartható fejlődés kérdései a Gyöngyösi kistérség településein

A kutatás célja a fenntarthatóság lokális, helyi (kistérségi, települési) megvalósítási lehetőségeinek, megoldási módjainak, ellentmondásainak és akadályainak feltárása. A kérdőíves vizsgálat az önkormányzatoknál és a lakosságnál is ismerethiányt és gyenge kezdeményezőkészséget jelzett. Igaz, napjainkban Magyarországon a fenntarthatóságot kormányzati és helyi szinten sem kezelik jelentőségének megfelelő helyen, s a nemzeti stratégia is csak 2007-re készült el. Útmutatók és esettanulmányok híján az önkormányzatok is csak tapogatóznak, és a lakosság sincsen tisztában a nemzetközi kezdeményezés jelentőségével. A törvényi háttér csak azt rögzíti, hogy a helyi hatóságok részt vehetnek ilyen stratégiák készítésében, de nem fogalmaz meg kötelezettségeket,...

A fenntartható fejlődést szolgáló paradigma
Provedor de dados: 31
Autores: Meszaros,   Sandor.
Az uralkodó neoklasszikus paradigma alapján a 20. század második felében a gazdasági növekedés a várható klímaváltozás, a Föld természeti erőforrásai és a társadalmi egyenlőtlenségek figyelembevétele nélkül ment végbe. Erre a helyzetre szolgált válaszul a fenntarthatóság koncepciója, amely az utóbbi két évtizedben globális mozgalommá vált, és nemzeti alkalmazkodási stratégiák kidolgozásához vezetett. A gazdaság működésére azonban igazán új paradigma mégsem született, bár a köz¬gazdaságtan a komplexitás irányába látszik fejlődni. Az új (transzdiszciplináris) paradigma eddigi hiánya ellenére a szükséges változások irányai már felismerhetők: a fosszilis energiaforrások mielőbbi helyettesítése és az erdőgazdaság kiemelt kezelése (Low Carbon Economy), valamint...

A fenntarthatóság mérése az erdőgazdaságban

Autores: Somogyi,   Zoltan.
A fenntarthatóság mérése, de definiálása is nehézkes a jövőre vonatkozó feltételezések bizonytalansága miatt. Korlátozott következtetések vonhatók le pl. a „kereslet és kínálat” összehasonlításának elvén alapuló, egyre közismertebb ökológiai lábnyomból, vagy más, a fenntarthatóság bizonyos aspektusait részletesebben jellemző indikátorok tényleges értékeinek és az előre elvárt értékek összevetéséből. Ilyen, fejlődő, korlátozott lehetőségeket nyújtó indikátorrendszer jött létre az erdőgazdálkodásban. A rendszer használatát nagymértékben korlátozza, hogy megalapozatlan az, hogy hány, illetve mennyire specifikus vagy mennyire aggregált indikátorokat alkalmaznak, és hogy az indikátorok mért értékeit hogyan értelmezik. Emiatt az indikátorértékek értelmezésében...

A financial analysis of the impact of sheep on the risks and returns associated with mixed enterprise dryland farming in south-eastern Australia: Part II
Provedor de dados: 31
Autores: Hutchings,   Timothy R.
This paper extends the long-term cash-flow simulations reported in Part I (Hutchings 2009) to include a range of seasonal scenarios at four representative dryland sites in south-eastern Australia. The effect of varying the proportion of sheep and cropping in the enterprise mix at each site on cash surpluses is discussed. The analysis shows that, for most sites, the cropping enterprises require better than average seasons, prices and water-use efficiencies to generate a positive cash flow and are subject to substantial variability and risk of loss. In contrast, the sheep enterprises show small but stable cash flows in all but extreme drought conditions. This paper emphasises the need to include site-specific, long-term variability and whole-farm costs in...

A first insight into genotype x diet interactions in European sea bass (Dicentrarchus labrax L. 1756) in the context of plant-based diet use
Provedor de dados: 5
Autores: Le Boucher, Richard; Vandeputte, Marc; Dupont-nivet, Mathilde; Quillet, Edwige; Mazurais, David; Robin, Jean; Vergnet, Alain; Medale, Francoise; Kaushik, Sadasivam; Chatain, Beatrice.
This preliminary study assessed genotype x diet interaction in late growth of European sea bass (Dicentrarchus labrax) fed with either a fish meal (FM)- or a fish oil (FO)-based diet (M) or an all-plant-based (PB) diet. A total of 550 fish from 224 families were reared together and tagged. DNA was sampled and microsatellites were used to assign parentage. When fish weight was 192 +/- 54 g, two tanks were fed with M (FM: 100%; FO: 100%) and two others with PB (FM: 0% and FO: 0%). Body weight (BW), fork length (FL) and fillet lipid content (CorrFat) were analysed with a linear model and with REML methodology. We observed no significant differences between groups, but a slightly lower (P=0.03) daily growth coefficient in sea bass fed PB than in those fed M....

A Flexible Parametric Family for the Modeling and Simulation of Yield Distributions
Provedor de dados: 31
Autores: Ramirez,   Octavio A.; McDonald,   Tanya U.; Carpio,   Carlos E.
The distributions currently used to model and simulate crop yields are unable to accommodate a substantial subset of the theoretically feasible mean-variance-skewness-kurtosis (MVSK) hyperspace. Because these first four central moments are key determinants of shape, the available distributions might not be capable of adequately modeling all yield distributions that could be encountered in practice. This study introduces a system of distributions that can span the entire MVSK space and assesses its potential to serve as a more comprehensive parametric crop yield model, improving the breadth of distributional choices available to researchers and the likelihood of formulating proper parametric models.

B udapesten és Győrben végzett négyszáz fős, megkérdezésen alapuló ökonometriai és hagyományos statisztikai feldolgozásból származó adatok alapján megállapítható, hogy az ökológiai gazdálkodásból származó termékek iránti városi fogyasztói igényt a megkérdezés helye, a megkérdezettek neme, az iskolai végzettség és a jövedelmi helyzet befolyásolta.

Autores: Marsalek,   Sandor; Deme,   Pal; Szabo,   Ferenc; Hagen,   Istvan Zsombor.
A Gyöngyösi Kistérségben végzett felmérés tapasztalatai azt mutatták, hogy élénkült a kistérség földpiaca. A földbérleti díjak és árak egyaránt emelkedő tendenciát mutattak, szélsőséges ingadozások mellett. A vizsgált időszakban ér-tékesítettek termőföldet hektáronként 80 ezer forintért és 4,5 millió forintért is. Egyszerre van jelen a földtől való mindenáron való szabadulás és a vétel szándé-ka. A jövőre nézve a földár és a haszonbérleti díj növekedése várható, de ez az EU átlag alatt alakul hosszabb távon is. A föld birtoklása – helyzetétől függően – a jövőben kimagasló hozamot biztosíthat, és várhatóan meghaladja a lekötött bankbetétek hozamát, sőt esetenként extraprofit is elérhető. A termelőeszközök közül ma már csak a földingatlan és a munkaerő...

A „Gazdálkodás” 2010. évi 2. számában vitacikkem jelent meg „A földbirtok-politikaválaszt igénylő kérdései” címen. Ezzel az volt a célom, hogy a témakörrel kapcsolatban felvessek kérdéseket, leírjak megállapításokat, és ezzel egy olyan vitát generáljak, ami fórumot ad a tudományos közélet szereplőinek a megszólalásra, a vélemények ütköztetésére, egymás nézeteinek jobb megértésére, a politika számára javaslatok megfogalmazására. A vitában az agrárgazdaságtan, üzemtan képviselői és mások kifejthették a véleményüket olyan fontos birtokpolitikai kérdésekkel kapcsolatban, mint a földtulajdon, a földhasználat, a földbérlet, a földpiac, a mezőgazdasági üzemszabályozás, a tagosítás, a föld öröklése, a külföldiek földhöz jutása, az állam szerepvállalása és ennek...

A földbirtok-politika választ igénylő kérdései

Autores: Kapronczai,   Istvan.
A kérdések széles területet ölelnek fel, ami folytatható a földvédelemmel, a kör-nyezetvédelemmel, a földadó kérdésével stb. A politikának – kompromisszumokkal és megegyezéssel – mielőbb lépnie kell, mert a rendezett birtokviszonyok növelik a földárat, élénkítik a termőföld iránti keresletet. Az emelkedő árak ugyanakkor bővítik a földkínálatot, végeredményben élénkül az egész földpiac. Ez a leghatékonyabb eszköz a termőfölddel kapcsolatos spekulációk visszaszorítására. Van-e azonban esély a megegyezésre? Politikai síkon aligha! Sőt az agrárközgazdász szakma is meglehetősen megosztott a birtok, a föld kérdésében, hisz körein¬ken belül is hatnak az érdekek, a megcsontosodott előítéletek. Mégis szükség van egy szakmai vitára, egy őszinte véleménycserére,...

Az üzemszabályozás magyarországi bevezetése olyan modellváltást eredményezne, amely a termőföld-tulajdonlás helyett a használatra helyezné a szabályozás hangsúlyait. Ezzel párhuzamosan olyan hatósági ellenőrzési rendszer kiépítésére is lehetőség nyílna, melyen keresztül hazánk a Római Szerződésben rögzített alapelvek (állampolgárságon alapuló diszkrimináció tilalma, tőkeáramlás és letelepedés szabadsága) megsértése nélkül is képes lehet megoldani a birtokpolitika nemzeti karakterét.  Az új szabályozási modellen keresztül a birtokaprózódás mérséklődése is elérhető az agrárüzem, mint dologösszesség egy egységben történő öröklésével anélkül, hogy csorbulna az örökhagyó tulajdonos üzeme feletti szabad rendelkezési joga.

A földpiaci sajátosságok és tendenciák
Provedor de dados: 31
Autores: Kurucz,   Adrienn.
Az elmúlt években ugyan emelkedtek a hazai földárak, de az uniós csatlakozástól várt jelentős árnövekedés és földpiaci forgalomélénkülés elmaradt, sőt, a bérleti díjakban sem hozott átütő fordulatot. A közelmúltban erősödött a magyarországi földpiac megmozdulását várók tábora, a 2011 májusában lejáró derogáció miatt. A szakemberek optimisták, mert a lejáró derogációval kiszélesedhet a vásárlói kör. A hazai agrárgazdaság egyik legnagyobb gondja a tőkehiány, ami akadályozza a technikai és technológiai fejlesztést, az ágazat versenyképessé és jövedelmezőbbé tételét. A földpiac megnyitása becslések szerint ezer milliárd forintot hozhatna az ágazatba, hatalmas lökést adhatna az innovációnak és ugrásszerűen javíthatna az agrárgazdaságból közvetve vagy...

A termékpályák tagoltsága, a termékpálya-fázisok eltérő koncentráltságából fakadó piaci formák a tevékenységi láncban kialakult áralkukat, valamint az elérhet ő árnyereséget, illetve árveszteséget meghatározzák. A számítási eredményeket a piac szereplőinek véleményével ütköztető vizsgálataink megerősítik, hogy a termékek túlnyomó részénél az erőfölény a legkoncentráltabb oldalnál, a kereskedelmi fázisban található. A kiskereskedelmi láncok nem csak egyértelműen árvezetők, de egyben a feldolgozott termékek importárain keresztül az egész vertikum áralakulását meghatározzák. A termelői és feldolgozói fázis között – nagyon kevés kivétellel – az árnyereség a feldolgozóknál figyelhető meg. Az ágazati szintű erőfölény vizsgálataink szerint termékenként erősen...

A framework for assessing impacts of community-based enterprises on poverty reduction: a case study in northern Thailand
Provedor de dados: 31
Autores: Terrakul,   Nuttamon; Villano,   Renato A.; Wood,   Fiona; Mounter,   Stuart W.
Poverty alleviation remains a challenge for Thailand’s socio-economic development. A key strategy of the Thai government to help meet this challenge at the ‘grass roots’ level has been the promotion of Community-Based Enterprises (CBEs). And national statistics and descriptive studies have shown that CBEs have led to both income improvement and employment creation. However, poverty is a multi-dimensional concept and also some groups are more adversely affected (such a women) than others. By investigating poverty from a number of different angles, this research aims to assess whether CBES are a genuine tool for poverty reduction at the individual household level. This paper provides an outline of the framework developed for assessing CBE impact on poverty...

Participatory research relies on stakeholder inputs to obtain its acclaimed benefits of improved social relevance, validity, and actionability of research outcomes. We focus here on participatory research in the context of natural resource management. Participants&amp;#8217; acceptance of participatory research processes is key to their implementation. Our first assumption is that this positive view and acceptance of participation in research processes is a public good for the whole participatory research community. We also assume that the diversity of participatory forms of research is rarely considered by potential participants when they make their decisions about whether or not to participate in a proposed process.

A framework for qualitatively evaluating management plans in a results-based perspective
Provedor de dados: 5
Autores: Rochet, Marie-joelle; Trenkel, Verena; Rice, Jake.
Currently many multi-year management plans are being developed either for rebuilding depleted stocks or for avoiding difficult negotiations when management decisions must be revisited on a regular basis. Management plans are commonly evaluated by intensive model simulations that describe the ecological and economic dynamics, and the management loop. Under the results-based management paradigm, the fishing industry or particular fishing sectors will develop their own management plans, potentially leading to a huge number of plans to be evaluated. Guidelines for evaluating the plans on a qualitative level before launching quantitative evaluations will be essential. Here we propose a framework for evaluating management strategies in a qualitative way. A...

Autores: van Wagenberg,   Coen P.A.; Backus,   Ge B.C.; van der Vorst,   Jack G.A.J.; Urlings,   Bert A.P.
Since 2005 the EU food industry has primary legal responsibility for food safety control. This requires new responsibilities and relationships between government and industry, and between companies. This research presents a framework for incentive systems for food safety control in supply chains. It emphasizes key elements of food safety control from multiple perspectives and provides insights for the design and analysis of incentive systems for food safety control. An incentive system combines inter-company incentive mechanisms with intra-company decision making processes to control a hazard within the legal environment. Incentive mechanisms, which consist of a performance measure and a performance reward, induce companies to use control measures. The...

A French environmental specimen bank of marine bivalves : archive of trace chemical contamination
Provedor de dados: 5
Autores: Claisse, Didier; Knoery, Joel.
Since 1979, the French Marine Monitoring network (RNO) has been regularly collecting blue mussels and oysters at some 100 characterized sites along the French shore. The bivalves are used as quantitative bio-indicators of coastal chemical contamination. Since 1981, the collected samples have been stabilized and archived in a sample bank. The sample collection is thus a continuously lengthening record of coastal contamination.  Bivalves are collected by the Ifremer coastal laboratories. In order to eliminate their faeces and pseudofaeces, molluscs are depurated for 24 hours in decanted sea water from the sampling area. They are then sized, shucked from their shell and frozen in pools of 20-50 animals. At the Dépt of Biogeochemistry and Ecotoxicology, the...

An understanding of agriculture&amp;#x27;s energy, material, and labor requirements is essential for achieving economic and ecological sustainability, and for assessing the effectiveness of relevant policy decisions (biofuel subsidies, regulations, labeling, etc.). Previous studies of energy, materials, and labor use in farming have been based on either unverified voluntary reporting or test plots, rather than on the high-resolution measurements of mass and energy flows. Here we present a recursive analysis of 1.25 million data points describing in unprecedented detail the resource transactions on a 60 ha farm functioning for over 6 years.

A Fully Calibrated Generalized CES Programming Model of Agricultural Supply
Provedor de dados: 31
Autores: Merel,   Pierre R.; Simon,   Leo K.; Yi,   Fujin.
The use of prior information on supply elasticities to calibrate programming models of agricultural supply has been advocated repeatedly in the recent literature (Heckelei and Britz 2005). Yet, Mérel and Bucaram (2009) have shown that the dual goal of calibrating such models to a reference allocation while replicating an exogenous set of supply elasticities is not always feasible. This article lays out the methodological foundation to exactly calibrate programming models of agricultural supply using generalized CES production functions. We formally derive the necessary and sufficient conditions under which such models can be calibrated to replicate the reference allocation while displaying crop-specific supply responses that are consistent with prior...

A vizsgálatok a múltbeli tendencia folytatásaként a búza, a kukorica vetésterületének csökkenését, illetve a napraforgó növekedését vetítik előre. A termésmennyiségek prognózisa azt mutatta, hogy a búza, a kukorica és a napraforgó esetében emelkedés várható, amit a hosszú távú ciklusok jövőben várható konjunktúrája még jobban fel fog erősíteni.

A kutatás célja az, hogy megállapítsuk, milyen habitussal rendelkeznek a gazdák, és melyikkel képesek eredményesen alkalmazkodni a piacgazdasághoz. A teljes munkaidőben dolgozó egyéni gazdákra az a jellemző, hogy nagyon szeretnek dolgozni, amit a szüleiktől örököltek. Valamennyien nagyon erős egyéniségek, ezért is építették ki a saját gazdasági autonómiájukat, amivel létrejött autonóm személyiségük is. A mezőgazdaságban az egyéni gazdák a gazdálkodás kialakításához a „készen talált” mintákat először is a háztájiból vették, továbbá a teljes kollektivizálás előtti családi gazdaságokból és csak harmadsorban a korábbi munkahelyi kapcsolatokból, tapasztalatokból.

A tanulmány bemutatja a hazai gabona keresletében bekövetkezett vertikális és horizontális átrendeződést és annak hatásait.

Megállapítható, hogy a gabonapiacon elsősorban a nagy kereskedelmi cégek és holdingok az árvezetők, ami méretükkel, tároló kapacitá-saikkal, logisztikai adottságaikkal és stratégiájukkal magyarázható. A feldolgo-zók (malom, takarmánykeverő, vetőmagos cégek), az integrátorok, kiskereskedők és egyéb cégek árelfogadók a gabonapiacon.

A Game Theoretic Framework for Cooperative Benefits in South Africa’s Land Redistribution Process: A Case of Northern Kwa-Zulu Natal Sugarcane Farmland Transfers
Provedor de dados: 31
Autores: Mbatha,    C. Nhlanhla; Antrobus,   G.G.
A good indicator of successful farm redistribution cases has to be the continuation of viable productivity rates in their post transfer periods. Continued productivity benefits all the stakeholders that are involved in the process. Unfortunately negative productivity levels have been reported in numerous South African land redistribution transfers in recent years. A game theoretic perspective is adopted to argue that cooperation among key stakeholders, which could be enforced through long term contracts between a land buyer, sellers and new owners, would lead to higher productivity levels and other benefits. Additional benefits would, for example, include market related prices paid by a buyer. Sugarcane farm transfer cases from two municipality districts...

A general extrudate bulk density model for both twin-screw and single-screw extruder extrusion cooking processes
Provedor de dados: 21
Autores: Cheng, Hongyuan; Friis, Alan; Høeg Hansen, Jonas; Tolderlund Rasmussen, Hanne.
Effects of extrusion parameters and raw materials on extrudate expansion are respectively investigated in a twin-screw extruder and a single-screw extruder extrusion cooking experiments for fish feed, wheat, and oat &amp; wheat mixture processing. A new phenomenological model is proposed to correlated extrudate bulk density, extrusion parameters and raw material changes based on the experimental results. The average absolute deviation (AAD) of the correlation is 2.2% for fish feed extrusion in the twin-screw extrusion process. For the single-screw extrusion process, the correlation AAD is respectively 3.03%, 5.14% for wheat and oat &amp; wheat mixture extrusion; and the correlation AAD is 6.6% for raw material change effects. The correlation results...

A general framework for indicator design and use with application to the assessment of coastal water quality and marine protected area management
Provedor de dados: 5
Autores: Beliaeff, Benoit; Pelletier, Dominique.
Environmental management decisions based upon indicators are the end point of a process involving stakeholders and scientists. These steps should be explicit and follow a chronology. This paper presents a general framework for the design and use of management-oriented indicators, integrating management questions and performance criteria. We first examined the desirable characteristics of indicators aimed at providing decision-support for marine environmental management. Ideally, one should select the indicator that guarantees a safe and unambiguous decision leading to the appropriate measures in terms of regulation, remediation or control. In the present study, indicators are assessed according to two criteria: relevance and effectiveness. Relevance...

A generic approach for representing complex structures in biological models
Provedor de dados: 17
Autores: Robert I. Muetzelfeldt.
Increasingly, the biological modelling community is looking for ways of handling complex and possibly dynamic structures in their models.   On the one hand, the pathway-modelling groups (SBML and CellML) seek to move up levels of organisation, while on the other hand the &amp;#x22;Virtual X&amp;#x22; communities (where X is some organism or organ) need to represent the organisational structure within their object of study.   To date, various approaches have been proposed, such as  the SBML Level 3 &amp;#x27;comp&amp;#x27;, &amp;#x27;spatial&amp;#x27;, &amp;#x27;array&amp;#x27; and &amp;#x27;dyn&amp;#x27; extension packages, and domain-specific elements in languages such as NeuroML, but there is no generic approach intended to be adopted by the various...

A genomic analysis of disease-resistance genes encoding nucleotide binding sites in Sorghum bicolor
Provedor de dados: 74
Autores: Cheng,Xiao; Jiang,Haiyang; Zhao,Yang; Qian,Yexiong; Zhu,Suwen; Cheng,Beijiu.
A large set of candidate nucleotide-binding site (NBS)-encoding genes related to disease resistance was identified in the sorghum (Sorghum bicolor) genome. These resistance (R) genes were characterized based on their structural diversity, physical chromosomal location and phylogenetic relationships. Based on their N-terminal motifs and leucine-rich repeats (LRR), 50 non-regular NBS genes and 224 regular NBS genes were identified in 274 candidate NBS genes. The regular NBS genes were classified into ten types: CNL, CN, CNLX, CNX, CNXL, CXN, NX, N, NL and NLX. The vast majority (97%) of NBS genes occurred in gene clusters, indicating extensive gene duplication in the evolution of S. bicolor NBS genes. Analysis of the S. bicolor NBS phylogenetic tree revealed...

Autores: Van Sebille, Erik; Wilcox, Chris; Lebreton, Laurent; Maximenko, Nikolai; Hardesty, Britta Denise; Van Franeker, Jan A.; Eriksen, Marcus; Siegel, David; Galgani, Francois; Law, Kara Lavender.
Microplastic debris floating at the ocean surface can harm marine life. Understanding the severity of this harm requires knowledge of plastic abundance and distributions. Dozens of expeditions measuring microplastics have been carried out since the 1970s, but they have primarily focused on the North Atlantic and North Pacific accumulation zones, with much sparser coverage elsewhere. Here, we use the largest dataset of microplastic measurements assembled to date to assess the confidence we can have in global estimates of microplastic abundance and mass. We use a rigorous statistical framework to standardize a global dataset of plastic marine debris measured using surface-trawling plankton nets and coupled this with three different ocean circulation models...

Autores: Ghermandi,   Andrea; Nunes,   Paulo A.L.D.
The welfare dimension of the recreational services provided by global coastal ecosystems is examined through a meta-analytical regression-based valuation approach.  First, we construct a global, state-of-the-art database of stated and revealed preference estimates on coastal recreation, which includes also the grey literature and with the latest entry updated to February 2010. Second, the profile of each of the 253 observations of our dataset, which correspond to individual value estimates, was further enriched with characteristics of the built coastal environment (site accessibility, anthropogenic pressure, level of human development), characteristics of the natural coastal environment (presence of protected area, type of ecosystem,  and marine...

A global mean sea surface temperature dataset for the Last Interglacial (129–116 ka) and contribution of thermal expansion to sea level change
Provedor de dados: 5
Autores: Turney, Chris S. M.; Jones, Richard T.; Mckay, Nicholas P.; Van Sebille, Erik; Thomas, Zoë A.; Hillenbrand, Claus-dieter; Fogwill, Christopher J.
A valuable analogue for assessing Earth's sensitivity to warming is the Last Interglacial (LIG; 129–116 ka), when global temperatures (0 to +2 ∘C) and mean sea level (+6 to 11 m) were higher than today. The direct contribution of warmer conditions to global sea level (thermosteric) is uncertain. We report here a global network of LIG sea surface temperatures (SST) obtained from various published temperature proxies (e.g. faunal and floral plankton assemblages, Mg ∕ Ca ratios of calcareous organisms, and alkenone UK′37). We summarize the current limitations of SST reconstructions for the LIG and the spatial temperature features of a naturally warmer world. Because of local δ18O seawater changes, uncertainty in the age models of marine cores, and differences...

A Global Model for Agriculture and Bioenergy: Application to Biofuel and Food Security in Peru and Tanzania
Provedor de dados: 31
Autores: Elbehri,   Aziz; McDougall,   Robert; Horridge,   Mark.
This paper describes a global model for agriculture and bioenergy (GLOMAB) that incorporates biomass, biofuels and bioelectricity sectors into the GTAP-Energy model by expanding the global GTAP database, production and consumption structures. Biofuels are separated between first- generation (sugar ethanol, starch ethanol) and second- generation (cellulosic ethanol) biofuels and associated biomass feedstocks (maize, sugar cane, crop residues, woody biomass). Beside biofuels, the model also incorporates bioelectricity (as separate form conventional electricity) which competes for the same biomass feedstocks with cellulosic ethanol sector (agricultural residues, woody biomass). With this broad-based representation of the bioenergy system likely to prevail...

A globalizáció és a konszolidációs számvitel alkalmazása a magyar élelmiszer-gazdaságban
Provedor de dados: 31
Autores: Simon,   Szilvia.
Aglobális pénzügyi és gazdasági válság kialakulása, a válság világméretű elterjedése számos okra vezethető vissza. Ezek között az okok között elsőként a globalizációt lehet kiemelni. Aglobalizáció folyamatában megfigyelhető a tőke, a szellemi erőforrások, az anyagi javak világméretű koncentrációja. Aglobalizáció egyik kísérőjelenségeként megfigyelhető az a tendencia, hogy a jogilag önálló agrár-, élel¬miszer-ipari és élelmiszer-kereskedelmi vállalkozások egymással érdekeltségi, részesedési viszonyba kerülnek, amelynek hatásaként a vállalkozások között a piaci viszonyok korlátozottá válnak. Így az egyedi éves beszámolók alapján a társaságok vagyoni, pénzügyi és jövedelmi helyzetének bemutatása nem biztosítható. Az információhiány megszüntethető, ha a...

A Globally Flexible Model for Crop Yields Under Weather Risk
Provedor de dados: 31
Autores: Cooper,   Joseph C.; Wallander,   Steven.
The literature on climate change and crop yields recognizes the need to allow for highly non-linear marginal effects.  This study combines these two areas of the literature by using Flexible Fourier Transforms (FFT’s) to ensure flexibility for both the time trend and the weather effects.  This study also illustrates how FFT’s can be combined with quantile regression (QR) to provide both robustness to outliers and information on the scale effects of time and weather variables. For U.S. county level data on corn, soybeans, and winter wheat, we estimate the relationship between yield and temperature and precipitation using a traditional parametric expected-yield estimator, our quantile-FFT regression evaluated at the median, and our QR-FFT regression that...

A growing oceanic carbon uptake: Results from an inversion study of surface pCO(2) data
Provedor de dados: 5
Autores: Majkut, Joseph D.; Sarmiento, J. L.; Rodgers, K. B.
Concerted community efforts have been devoted to producing an authoritative climatology of air-sea CO2 fluxes, but identifying decadal trends in CO2 fluxes has proven to be more challenging. The available surface pCO(2) estimates are too sparse to separate long-term trends from decadal and seasonal variability using simple linear models. We introduce Markov Chain Monte Carlo sampling as a novel technique for estimating the historical pCO(2) at the ocean surface. The result is a plausible history of surface pCO(2) based on available measurements and variability inferred from model simulations. Applying the method to a modern database of pCO(2) data, we find that two thirds of the ocean surface is trending toward increasing uptake of CO2, with a mean (year...

Az éghajlatváltozás hatásai a minőségi termelés követelményei, a rentábilis termelés igénye, a termeléstechnológiai elemek megújításának, korszerűsítésének szükségessége egyaránt sürgetik a fenti követelményeket szem előtt tartó, annak megfelelni akaró módszert, a szabadföldi intenzív termelést, melynek legfontosabb elemei: az időszakos talaj-, növény- és légtértakarás, a víztakarékos öntözési módok alkalmazása és a retardált műtrágya használata.  Az időszakos talaj-, növény- és légtértakarással a szedési időszak meghosszabbítható, és egyúttal javítható a talaj vízgazdálkodása, valamint visszaszorítható a gyomosodás. A mikroöntözés alkalmazásával, azonos vízmennyiséggel kétszer akkora terület öntözhető. Retardált (fékezett lebomlású) műtrágyák...

A Hedonic Metric Approach to Estimating the Demand for Differentiated Products: An Application to Retail Milk Demand
Provedor de dados: 31
Autores: Gulseven,   Osman; Wohlgenant,   Michael K.
This article introduces the Hedonic Metric (HM) approach as an original method to model the demand for differentiated products. Using this approach, initially we create an n-dimensional hedonic space based on the characteristic information available to consumers. Next, we allocate products into this space and estimate the elasticities using distances. What distinguishes our model from traditional demand models such as Almost Ideal Demand System (AIDS) and Rotterdam Model is the way we link elasticities with product characteristics. Moreover, our model significantly reduces the number of parameters to be estimated, thereby making it possible to estimate large number of differentiated products in a single demand system. We applied our model to estimate the...

A Hedonic Price Analysis of Corn and Soybean Herbicides
Provedor de dados: 31
Autores: Vassalos,   Michael; Dillon,   Carl R.
Herbicides account for approximately 2.2% of total farm expenses and are applied to more than 80% of farmland in the USA. The widespread adoption of herbicides contributed to the increased and relatively cheaper productivity of modern intensively managed agricultural systems in developed countries. The present study uses a hedonic framework to analyze the effect of selected attributes on the price of corn and soybean herbicides. Two different empirical models were estimated separately for the two crops. The data include information on 51 herbicides, 27 for corn and 24 for soybean crops used in Kentucky. Findings indicate that efficacy against weeds and crop response (illustrates the potential of an herbicide to injure a crop) of herbicides are significant...

A Hedonic Pricing Model for German Wine
Provedor de dados: 31
Autores: Schamel,   Guenter.
We develop a hedonic pricing model for German quality wine. Quality indicators for 4,141 wines are sensory awards received at the annual German wine competition and the legally required quality category as well as a set of control variables including regional origin, color, style, and their age at the time of judging. The data confirms that sensory quality awards have a significant and positive price impact. Moreover, we estimate significant relative differences between quality categories, growing regions and most of the control variables.

A herbal feed additive shows potential to improve metabolic situation in early lactating dairy cows
Provedor de dados: 21
Autores: Walkenhorst, M.; Ivemeyer, S.; Schaette, R.; Mayer, P.; Arndt, G.
The gap between performance and feed intake in early lactating dairy cows often leads to metabolic imbalance which is connected to udder inflammation (UI).  A study with 72 dairy cows calving from November 2010 to March 2011 on 10 Swiss and German farms was conducted to test the effect of a herbal feed additive (HFA) containing mainly Urtica dioica L. (herba), Silybum marianum (L.) Gaert. (fructus), Artemisia absinthium L. (herba) and Achillea millefolium L. (herba).  Cows were stratified (farm and milk yield) randomised divided into three groups. From 14 days prior predicted calving to the end of the following lactation cows received daily 100 g pellets containing A: 100% HFA, B: 50% HFA and 50% alfalfa and C: 100% alfalfa (placebo). Two or three cows per...

A high-resolution reconstruction of palaeoceanographic conditions in the glacial Southern Ocean (Scotia Sea and Adelie Land Coast)
Provedor de dados: 5
Autores: Collins, Lewis G.
Antarctic sea-ice is a critical component of the climate system, an enhancer of glacial climate and, as recently hypothesised by modelling studies, a potential driver of the millennial scale climate variability that dominated the last glacial cycle (LGC). Unfortunately a severe lack of glacial sea-ice records from the Southern Ocean has so far prevented the testing of this hypothesis with field data. In this thesis, I present detailed reconstructions of Antarctic sea-ice and ocean conditions derived from diatom assemblages and the first application of highly branched isoprenoid biomarkers to glacial sediments. These sea-ice sensitive proxies were measured in high-resolution, glacial sediment cores from the Scotia Sea (Southwest Atlantic, West Antarctica)...

A histological examination of grafting success in pearl oyster Pinctada margaritifera in French Polynesia
Provedor de dados: 5
Autores: Cochennec-laureau, Nathalie; Montagnani, Caroline; Saulnier, Denis; Fougerouse, Angelique; Levy, Peva; Lo, Cedrik.
Pearl oyster grafting is a complex surgical operation that should lead to pearl formation after approximately eighteen months. Although this technique has been used for many years in French Polynesia, the grafting process is still not standardised. While studies have been carried out in order to improve graft performance and yield, these remain highly variable due to post-grafting mortality, nucleus rejection and unreliable pearl quality, all of which constrain pearl farm profitability. The present study uses histological analysis to monitor oysters that either rejected or retained their nuclei. Both groups of oysters are compared in terms of evolution of the graft, which could influence retention, and the development of a pearl sac in cases where grafting...

A History of Violence: Testing the ‘Culture of Honor’ in the US South
Provedor de dados: 31
Autores: Grosjean,   Pauline.
Using historical data on early settlers to the United States, this paper tests and confirms the “Culture of Honor” hypothesis by socio-psychologists Dov Cohen and Richard Nisbett (1994, 1996). This hypothesis argues that the high prevalence of homicides in the US South stems from the fact that it was a frontier region settled by people whose economy was based on herding: the Scotch-Irish. Herding societies develop cultures of honors for reasons having to do with their precariousness: violence is a necessary condition to preserve a reputation for toughness and deter animal theft. Using historical census data on waves of settlers from Europe and relating contemporaneous violence to early Scotch-Irish settlers, this paper provides a test of the link between...

A Hybrid Approach to the Valuation of Climate Change Effects on Ecosystem Services: Evidence from the European Forests
Provedor de dados: 31
Autores: Ding,   Helen; Silvestri,   Silvia; Chiabai,   Aline; Nunes,   Paulo A.L.D.
In this paper we present a systematic attempt to assess economic value of climate change impact on forest ecosystems and human welfare. In the present study, climate change impacts are downscaled to the different European countries, which in turn constitute the elements of our analysis. First, we anchor the valuation exercise in the Millennium Ecosystem Assessment (MEA) Approach and therefore the link between the different forest ecosystem goods and services, including provisioning, regulating and cultural services, human well-being and climate change. Second, climate change is operationalized by exploring the different storylines developed by the International Panel on Climate Change (IPCC) and applied, downscaled, for each of the European countries under...

A hydrometric analysis of the Moose Jaw River near Burdick (05JE006): Temporal trends and frequency analyses for mean, minimum, and maximum flows
Provedor de dados: 17
Autores: Sierra Rayne; Kaya Forest.
A hydrometric analysis over the available historical record (1973-2010) was conducted for the Moose Jaw River station near Burdick in south-central Saskatchewan, Canada. Frequency analyses on mean monthly, average annual, monthly minimum/maximum, and annual minimum flows generally yielded poor fits, and problems with negative flow predictions for mid- to long-term return periods regardless of distribution type. The annual maximum streamflow time series is reasonably well-described by linear and log Pearson Type III distributions, although both distribution types underestimate extreme maximum flows. Mann-Kendall linear time series analysis on mean monthly and annual streamflows reveals no trend in annual water yields, nor in mean monthly flows between March...

A Hypothetic Mechanism of Ordering  and Shaping Cells within Discrete Regions
Provedor de dados: 17
Autores: Yaroslav Strokovskyy.
We propose a hypothetic mechanism of ordering and shaping cells during _C. elegans_ embryogenesis. The mechanism is based on the assumption that during each round of division of cells, daughter cells acquire electric charges from its mother cells (charge conservation law is taken into account). Between the acts of division, the total electric field, generated by a system of charged cells, change relative positions of the charged cells within the region. In one&amp;#x2019;s turn, the positions of the charged cells determine the pattern of the electrostatic field. A mathematical model of such self-consistent mechanism is developed. The process of developing the sixteen-cell structure starting with one cell is simulated. The results correspond to the known...

Autores: Silveira,João Paulo Generoso; Amarante,Cassandro Vidal Talamini do; Steffens,Cristiano André; Miqueloto,Aquidauana; Katsurayama,José Masanori.
O "bitter pit" é um distúrbio fisiológico ocasionado pela deficiência de cálcio (Ca) em maçãs. No entanto, trabalhos recentes mostram que o "bitter pit" pode estar relacionado com aumento na atividade de giberelinas nas plantas. Este trabalho teve como objetivo avaliar os efeitos da pulverização de macieiras com um inibidor da síntese de giberelinas, o prohexadiona-cálcio (ProCa), e com giberelina GA3, no crescimento vegetativo das plantas e na ocorrência de "bitter pit". O experimento foi conduzido em um pomar localizado no município de São Joaquim-SC, na safra de 2009/2010. Macieiras 'Catarina' e 'Fuji' foram pulverizadas com água (tratamento-controle), ProCa e GA3 (ambos os produtos na dose de 319 mg L-1), na queda das pétalas (15-10-2009), quando as...

Autores: Setto,   Giani Claudia; Brasil,   Gutemberg H.; Vieira,   Wilson da Cruz.
The aim of this paper was to analyze the relative importance of the steel industry to the state of Espírito Santo, Brazil. The 1990 and 1999 Brazilian input-output matrices and Brazil’s regional accounts - state of Espírito Santo were used to build input-output matrices (1990 and 1999) to this state. Increases in final demand were simulated to analyze the effects on the production of each sector as well as on employment creation in this state. Backward and forward linkage indexes were also computed to twelve sectors with the same purpose. The results show that the steel industry is very important to the capixaba economy especially due to the high multiplier effects in response to increases in final demand. The results show also that the relative importance...

A irradiação gama no tempo de cocção e na absorção de água em grãos de soja com e sem lipoxigenase
Provedor de dados: 65
Autores: Biscaro,Luciana Marino e; Brazaca,Solange Guidolin Canniatti; Arthur,Valter; Dias,Carlos Tadeu dos Santos.
O processamento térmico adequado contribui para aumentar a digestibilidade e eliminar fatores antinutricionais presentes em grãos. Porém, esse processo pode ser prejudicial, causando a perda de nutrientes. A irradiação de grãos pode facilitar sua cocção, reduzindo o tempo de amolecimento. O objetivo do presente trabalho foi avaliar possíveis alterações causadas pela irradiação no tempo de cocção e embebição de grãos de soja convencionais e sem lipoxigenase. As duas cultivares analisadas ('BRS 232' - com lipoxigenase e 'BRS 257' - sem lipoxigenase) diferiram entre si na quantidade de água absorvida, no tempo de embebição e no tempo de cocção dos grãos. A irradiação dos grãos, nas doses de 4kGy e 8kGy, diminuiu a absorção de água e o tempo de cocção.

A szerzők vizsgálataikban a hazai juhtenyésztés jövedelmezőségének és ver-senyképességének javítása érdekében két biotechnikai eljárás – az ivarzás-indukálás és a mesterséges termékenyítés – gyakorlati alkalmazásával és ökonó-miai elemzésével foglalkoztak. Magyar merinó juhokat, továbbá lacaune és lacaune keresztezett jerkéket próbáltak vemhesíteni szezonon kívül, május végén, ivarzás-indukálás után. Így az állatokat a szokásos vemhesítési periódus előtt, négy hónappal korábban vették tenyésztésbe, megcélozva ezzel a magasabb vágóállat felvásárlási árakat. A kezelések költségét jelentős mértékben megha-ladta a bárányonként elérhető extraprofit, amit a decemberi – keresleti piacra történő – bárányértékesítéskor értek el, ráadásul a laktációs idő és a kifejt...

A Kibbutz Dilemma: Social Movement or Self-Interested Group?
Provedor de dados: 31
Autores: Avrahami,   Eli.
One of the characteristics of the kibbutz was that it belonged to a nation-wide movement, it was open to the outside world and was involved in all aspects of society. In view of the changes taking place in the kibbutzim and in their surroundings the kibbutz may forfeit its characteristics as an assertive and centralized, or at least federative, organization. In consequence the kibbutz may cease to be a social movement seeking to attain goals of universal value and turn into an organized self-interested pressure group. The dilemma faced by the kibbutz is whether it will be a system of egotistic people seeing themselves as shrewd-calculating-yuppies, or members of a social movement seeking to attain goals of universal value, considered by others as "freiers"

A Közös Agrárpolitika reformja magyar (kutatói) szempontból
Provedor de dados: 31
Autores: Udovecz,   Gabor.
Az EU Közös Agrárpolitikája az állandó kompromisszumok és a sorozatos reformok terméke. Most annyiban más a helyzet, hogy a döntéshozatali mechanizmusban a szokásosnál is nagyobb a társadalmi nyomás, emiatt pedig a pénzügyi determináltság. A jövő alakításában pedig mi magyarok is részt veszünk. Kivételes lehetőség tehát, hogy hazánk adottságai (erősségek, gyengeségek) alapján határozott agrárorintációt fejezzen ki, s ennek fő törekvéseire építse az ország KAP-álláspontját. Magyarország olyan KAP-ban érdekelt, amely – európai értékek mentén – minél több uniós forrást biztosít, de tágítja is a mozgásteret a nemzeti agrár- és vidékpolitikai célok megvalósításához. Összefoglalóan kiemelhető, hogy a KAP-reform döntési mechanizmusa bonyolult, Magyarország...

A közvetlen agrártámogatások feltételezett csökkentésének becsült hatásai Magyarországon
Provedor de dados: 31
Autores: Dorgai,   Laszlo; Udovecz,   Gabor.
A 2013 utáni időszakra szóló KAP-reform keretében egyes tagállamok máris felvetették a közvetlen termelői támogatások jelentős csökkentését. Acikk 2006. évi támogatási és jövedelmi adatok alapján azt vizsgálja, hogy egy drasztikus, 50 százalékos támogatáscsökkenésnek milyen hatásai valószínűsíthetők, ha a termelés egyéb feltételei nem változnának. Az elemzés szerint egy ilyen lépésnek Magyarországon sokrétű és rendkívül hátrányos következményei lennének, nemcsak a mezőgazdaságra, hanem az egész nemzetgazdaságra, különösképpen pedig a vidéki foglalkoztatási viszonyokra és a természeti környezetre nézve. Minden szempontból hátrányosan érintené általában a vidéket, különösen a lemaradó és stagnáló kistérségeket, továbbá a kedvezőtlen adottságú területeket,...

We investigated the association between two single nucleotide polymorphisms (SNPs) in the adiponectin gene (rs822395 and rs266729) and coronary artery disease (CAD) in a case-control study of 198 unrelated Chinese CAD patients (with ; 70% coronary stenosis or previous myocardial infarction) and 237 non-CAD controls. The ligase reaction was used to detect SNPs rs822395 and rs266729, and the allelic association of these SNPs with the occurrence and severity of CAD was assessed. There were no significant differences in the genotypic or allelic frequencies of the two SNPs between control and CAD individuals. In addition, there was no association between the two SNPs and the severity of CAD based on the number of diseased vessels. The frequencies of alleles C...

A 4-year bacteriological survey (2003-2007) of four molluscs cultivated in France and faced with mortality episodes was performed by the French shellfish pathology network. The more abundant bacteria isolated during 92 mortality episodes, occurring mainly in Pacific oyster Crassostrea gigas, were identified by genotyping methods. It allowed us both to confirm the representativeness of Vibrio splendidus and Vibrio aestuarianus bacterial strains and to identify both a large number of Vibrio harveyi-related strains mainly detected during 2007 oyster mortality outbreaks and to a lesser extent bacterial strains identified as Shewanella colwelliana. Because metalloprotease has been reported to constitute a virulence factor in a few Vibrio strains pathogenic for...

A Latent Variable Approach to Multivariate Quantitative Trait Loci
Provedor de dados: 17
Autores: Bob O&amp;#x27;Hara; P&amp;#xe4;ivi  Komulainen; Outi  Savolainen; Mikko J. Sillanp&amp;#xe4;&amp;#xe4;.
A novel approach based on latent variable modelling is presented for the analysis of multivariate quantitative and qualitative trait loci. The approach is general in the sense that it enables the joint analysis of many kinds of quantitative and qualitative traits (including count data and censored traits) in a single modelling framework. In the framework, the observations are modelled as functions of latent variables, which are then affected by quantitative trait loci.  Separating the analysis in this way means that measurement errors in the phenotypic observations can be included easily in the model, providing robust inferences. The performance of the method is illustrated using two real multivariate datasets, from barley and Scots pine.

Autores: Lartaud, Franck; Emmanuel, Laurent; De Rafelis, Marc; Ropert, Michel; Labourdette, Nathalie; Richardson, Christopher A.; Renard, Maurice.
Cathodoluminescence (CL) microscopy of the foliated calcite shell hinge sections of live-collected oyster Crassostrea gigas collected at seven locations along a latitudinal gradient from the Netherlands in the North Sea to the Atlantic coast of France, revealed variations in luminescence that were attributable to seasonal variations in calcification of the hinge. Photomicrographs of hinge sections and luminescence profiles were analyzed to define a micro-sampling strategy that was adopted to drill the hinge samples to determine their isotopic composition. Reconstructed seasonal seawater temperatures determined from the stable oxygen isotope (delta O-18) composition along growth profiles from 32 oyster shell hinges showed distinct seasonal isotopic cycles...

A LEADER Program hazai gyakorlatáról
Provedor de dados: 31
Autores: Varga,   Eszter.
A LEADER Programban az ország területén közel száz helyi akciócsoport működik a települési önkormányzatok, vállalkozások és civil szervezetek együttműködésében, amivel lehetőség nyílott az alulról jövő, a helyi érintettek igényeit is figyelembe vevő széles körű és integrált vidékfejlesztésre. Ezt a lehetőséget azonban egyelőre nem sikerült kellően hasznosítani. Ennek alapvető okai között említhető a megfelelő időben végzett átfogó és korábbi tapasztalatokra építő tervezés hiánya, az akciócsoportok autonómiájának alacsony szintje, a megvalósítás rendszerének túlbonyolítása, rugalmatlansága, valamint a résztvevők folyamatos és széles körű aktív részvételének hiánya. Továbbá megállapítható, hogy a magyarországi LEADER Program alapvető problémáinak,...

A produção de citros no Brasil tem sido orientada para o mercado de suco concentrado congelado, embora no Nordeste esteja dividido entre o mercado de frutas frescas e indústria de suco. A limeira ácida 'Tahiti' é uma importante variedade comercial de citros no Brasil e o limoeiro 'Cravo', seu principal porta-enxerto, apresenta suscetibilidade à gomose de Phytophthora, reduzindo a longevidade das plantas. O 'Tahiti CNPMF 2001' apresenta caneluras acentuadas de tristeza, não apresenta sintomas de descamamento eruptivo, está livre do viróide da exocorte e é considerado resistente à bactéria Xylella fastidiosa, causadora da CVC.

A low concentration of ouabain (0.18 µg/kg) enhances hypertension in spontaneously hypertensive rats by inhibiting the Na+ pump and activating the renin-angiotensin system
Provedor de dados: 56
Autores: Siman,F.D.M.; Stefanon,I.; Vassallo,D.V.; Padilha,A.S.
We investigated the effects of low ouabain concentrations on systolic (SAP) and diastolic (DAP) arterial pressures and on pressor reactivity in 3-month-old male spontaneously hypertensive rats (SHR). Arterial blood pressure (BP) and pressor reactivity to phenylephrine (PHE) were investigated before and after 0.18 μg/kg ouabain administration (N = 6). The influence of hexamethonium (N = 6), canrenone (N = 6), enalapril (N = 6), and losartan (N = 6) on ouabain actions was evaluated. Ouabain increased BP (SAP: 137 ± 5.1 to 150 ± 4.7; DAP: 93.7 ± 7.7 to 116 ± 3.5 mmHg; P&lt;0.05) but did not change PHE pressor reactivity. Hexamethonium reduced basal BP in control but not in ouabain-treated rats. However, hexamethonium + ouabain increased DAP sensitivity to...

Autores: Fernandes,Flávio Lemes; Picanço,Marcelo Coutinho; Chediak,Mateus; Fernandes,Maria Elisa Sena; Ramos,Rodrigo Soares; Moreira,Suzana de Sá.
The objective of this work was to evaluate the use of a low-cost trap to capture Cerambycidae in different seasons in planted forests in Brazil. Thirty polyethylene-terephthalate trap bottles per hectare were used, disposed at every 50 m. The traps were red painted and contained glass flasks with a mixture of ethanol, methanol and benzaldehyde. There were soap and water at the trap bottom. The traps were checked biweekly for beetle presence. Sampling time required one minute per sample, and traps were easy to use. Total sampling cost, including materials and labor, was US$ 13.46 per sample. Six Cerambycidae species were captured along the dry and rainy seasons.

A magyar agrárgazdaság helyzete
Provedor de dados: 31
Autores: Kapronczai,   Istvan; Udovecz,   Gabor.
A 2008. év második felében kirobbant és fokozatosan elmélyülő pénzügyi-gazdasági válság súlyos piacvesztést eredményezett a magyar nemzetgazdaságban. Az ipari termékek külpiaca beszűkült, az építőipar pedig a fizetőképes kereslet csökkenése folytán került válságba. Ezekben az ágazatokban drasztikusan emelkedett a munkanélküliség. A válság kisebb mértékben érintette az élelmiszer-gazdaságot, amely elsősorban annak tulajdonítható, hogy keresletcsökkenés legkevésbé az élelmiszer-gazdaság termékeinél jelentkezett. Levonható az a következtetés, hogy a válságkezelésben stabilizáló tényező lehet az élelmiszer-gazdaság. Ezt igazolja, hogy az agrárgazdaság termékkibocsátása 2008-ban is jelentősen növekedett, s lényegében ez tette lehetővé a 2008-ban bekövetkezett –...

A magyar agrárgazdaság versenyesélyei és stratégiai dilemmái
Provedor de dados: 31
Autores: Udovecz,   Gabor; Popp,   Jozsef; Potori,   Norbert.
Szerzői kollektívánk az AKI 2007/7. számú tanulmányában (Alkalmazkodási kényszerben a magyar mezőgazdaság) megállapította, hogy a magyar agrárgazdaság viszonylag nagy kilengésekkel ugyan, de kényszerpályán sodródik, és kibocsátásának volumenét 2013-ig csak 6%-kal képes növelni, azt is torz szerkezetben. A behatárolt mozgástérben a mezőgazdaságból származó jövedelmek reálértéke – szintén túlzott ágazati aránytalanságokkal – legfeljebb a 2006. évi szinten marad. Rámutattunk azonban arra is, hogy ez a kedvezőtlen prognózis nem fátum, még módosítható, hiszen az adottságok alapján kínálkozik egy dinamikusabb fejlődési pálya is, amelyen a termelés volumene mintegy 25%-kal, a vállalkozói jövedelmek reálértéke pedig akár 50%-kal bővülhet. Egy évvel később az...

A magyar élelmiszer-gazdaság aggregált szintű külkereskedelmi teljesítménye az EU-csatlakozást követően
Provedor de dados: 31
Autores: Nagy,   Zsuzsanna.
A szerző a magyar élelmiszer-gazdaság külkereskedelmi teljesítményét vizsgálja az EU-15 piacain a csatlakozást követően. A versenyképesség mérésére különböző modellek és mutatószámok ismertek. A hazai élelmiszer-gazdaság külkereskedelmi teljesítményét cserearány-index, koncentrációs mutató, klasszikus Grubel-Lloyd index, egyszerű RCA mutató indikátorokkal vizsgálva megállapítható, hogy a cserearány-index a 2006-2008 közötti években kedvezőbben alakult az előző három évinél. Az élelmiszer-gazdaság export- és import-koncentrációja (H-index) csökkent 2004-től, de az agrárimport továbbra is koncentráltabb; az ágazaton belüli kereskedelem szerepe (GL-index) többnyire nőtt az EU-15 piacain, azonban az értékek jelentősen szóródnak tagállamonként és...

A magyar gabonaágazat középtávú kilátásai
Provedor de dados: 31
Autores: Potori,   Norbert; Varga,   Edina.
Igaz, hogy a szélsőséges időjárás Magyarországon rendkívül nagy hozamingadozásokat okozhat, az agrárpolitika és a piaci szereplők pedig hajlamosak a túlzott reakciókra, mégis a gabonaágazat az, ahol a magyar mezőgazdaság a természeti adottságok, a termelés vonatkozásában még bizonyíthatóan komparatív előnyökkel rendelkezik az Európai Unióban. A szántóföldi növények nemzeti kiegészítő támogatása ugyan 2008-tól a termeléstől függetlenedik, de a gazdálkodók a rendelkezésre álló szántóterületet a jövőben is hasznosítják, mert a gabonafélék magas ára ösztönzi a termelést. A kidolgozott különböző modellváltozataink szerint a hazai búzatermelés 4,6-6,1 millió tonna, míg a kukoricatermelés 9-10,9 millió tonna között alakulhat 2013-ban. A hazai abrakfogyasztó...

A magyar marhahús versenyesélyei az EU-ban
Provedor de dados: 31
Autores: Meszaros,   Kornelia; Beres,   Daniel.
A tanulmány a magyarországi vágásra szánt, élőszarvasmarha-külkereskedelem versenyképességét, komparatív előnyeit és hátrányait vizsgálja az 1999–2010 közötti időszakban. A marhahús jelentős része elsősorban exportra kerül. Vizsgálva ennek versenyképességét megállapítható, hogy jelenleg komparatív hátránya van az EU27-en belüli marhahúspiacon. A mutatók tendenciáját tekintve a hátrány mértéke évről évre csökkenő. Az RSCA-átlag mutatója a folyamatos emelkedést követően 2008-ban pozitív volt. A külkereskedelmi mérleg minden vizsgált évben aktív. A 2008-ban kibontakozott pénzügyi válság hatása ugyanakkor érződött, s jelentős visszaesést okozott, ami mindhárom mutató értékeiben megnyilvánult. A Gehlhar és Pick által kidolgozott kategóriák alapján pedig...

A magyar mezőgazdaság finanszírozásának főbb elemei a pénzügyi válságban
Provedor de dados: 31
Autores: Kemeny,   Gabor.
Kutatásunk eredményeként megállapítottuk, hogy a mezőgazdasági finanszírozás fontosabb csatornái a közvetlen banki finanszírozás és a közvetett banki finanszírozás. Ez utóbbinál a bank nem közvetlenül a termelőt, hanem egy köztes szervezetet, leggyakoribb esetben lízingcéget, faktoringcéget vagy integrátort finanszíroz. A nem-banki finanszírozás legfontosabb szereplői pedig a mezőgazdasági inputanyag-gyártók, a szállítók. A pénzügyi válság, amely 2008 őszén érte utol Magyarországot, jelentősen eltérő hatást gyakorolt az egyes mezőgazdasági finanszírozási csatornákra. Míg a jellemzően külföldi tulajdonosi körrel rendelkező hazai bankok közvetlen ügyfélkörüket (bár szigorúbb feltételekkel) hajlandóak voltak folyamatosan finanszírozni (sok esetben a kieső...

A magyar, német, lengyel és szlovák tejtermékek fázisárainak összehasonlítása

Autores: Aliczki,   Katalin; Mandi-Nagy,   Daniel; Nyars,   Levente; Papp,   Gergely.
A 2006–2009 közötti időszakban a tej fogyasztói ára Magyarországon volt a legmagasabb. A fogyasztói árak közötti árkülönbségek mögött számos tényező húzódik meg: az áfatartalom, a kereskedelmi láncok árpolitikája, a feldolgozói ár és végül a termelőknek fizetett felvásárlási ár. Az áfa mértéke alapvetően makrogazdasági adottság, egy adott ország gazdaságpolitikájának függvénye. Az EU régi tagállamaiban a kiskereskedelmi láncokkal kialakult kapcsolatrendszer és a piaci kultúra évtizedes fejlődés eredménye. Ezzel szemben a kelet-európai élelmiszerpiac szereplőire valósággal rászakadt az új típusú, tőke intenzív kiskereskedelem, ami a korábban megszokotthoz képest alárendelt helyzetbe hozta az értékesítési láncban a beszállítókat, a termelőket.

Autores: Gyarmati,   Gabor.
A hazai ökológiai gazdálkodás növekedési pályára állt az ezredforduló táján, de 2004-től a vállalkozások számának és az ökológiai művelés alá vont területek nagyságának növekedési mértéke csökkent, majd visszaesés következett be. Az ökológiai termelést végző vállalkozások nagy része jó adottságokkal rendelkező nagygazdaság, amelyek párhuzamos termelést folytatnak, és olyan elkötelezett kisvállalkozás, amelyek gazdasági súlya nem jelentős. Egyes rossz adottságú gazdaságok földjeiket átállítják ökológiai státuszra, a támogatás végett. A műve-lési ágak között nagyobb a gyep (rét, legelő, 53,6%) és alacsonyabb a szántó (26,4%) aránya.

Autores: Nyars,   Levente.
A dinamikusan fejlődő gazdaságú vagy a feltörekvő országokban, elsősorban Indiában, Kínában és Oroszországban mind több az állati eredetű termékek iránti igény. Termelésük azonban nem képes lépést tartani a fizetőképes kereslet növekedésével, ezért mind mezőgazdasági alapanyagokból, mind magas feldolgozottságú termékekből importra szorulnak. Az állati eredetű termékek előállításának növeléséhez azonban egyre több takarmány szükséges, nő a gabonafélék és olajnövények iránti globális igény is. A sertés- és baromfitartóknak a bioüzemanyag-gyártás támaszt erősödő versenyt. A magyar sertés- és baromfitartók érdemben nem képesek befolyásolni sem a világpiacon, sem az Európai Unió piacán zajló folyamatokat, így gazdasági környezetükhöz kénytelenek alkalmazkodni,...

A háztáji termékfeldolgozással, annak törvényi szabályozása miatt nem foglalkoznak, pedig az ízvilág megismertetése a fogyasztókkal remekül beilleszthető a vendégfogadásba. Jelenleg értékesítési nehézségekkel küzdenek a termelők.

A magyar tejvertikum diagnózisa
Provedor de dados: 31
Autores: Popp,   Jozsef; Potori,   Norbert; Papp,   Gergely.
Magyarország tejtermelése az EU-csatlakozást követően visszaesett. A többnyire alacsony átvételi árak és a szigorúbb minőségi követelmények miatt az elmúlt években sok tejtermelő kiszorult a piacról. A tej- és tejtermékek külkereskedelmében 2004 óta mind volumenben, mind értékben nettó importőri pozícióba kerültünk.  A tejkvóta-rendszer fokozatos kivezetése (a hazai kvóta kihasználtsága alig éri el a 85%-ot) a hazai tejágazatot közvetetten érintheti: a hatékonyabban ter¬melő tagállamok kerülhetnek előnybe a számunkra fontos olaszországi piacon, így értékesítési lehetőségeink szűkülhetnek, a hazai árakra még nagyobb nyomás nehezedhet.  Magyarországon a tejfeldolgozás koncentráltsága a vállalatok nagy száma ellenére viszonylag erős. A tejipar kettős prés...

A magyar zöldség- és gyümölcságazatok külkereskedelmi versenyképességének alakulása
Provedor de dados: 31
Autores: Medina,   Viktor.
A vizsgálatok eredményei alapján megállapítható, hogy a zöldség- és gyümölcságazatok versenyképesek, de a versenyképesség évről évre csökken. A versenyképesség romlása az uniós csatlakozással nem szűnt meg, sőt erősödött, ami részben az ágazat felkészületlenségének, részben a 2004. évi bő termésnek és a 2005. év kedvezőtlen időjárásának köszönhető. Kedvezőtlen eredmény az is, hogy a pozícióromlás legnagyobb mértékben a célpiacokon észlelhető. A termékköröket külön elemezve látható, hogy a versenyképességi mutatók a legkedvezőbbek a feldolgozott termékeknél. Ezt követik a friss zöldségek. A friss gyümölcsnél már nem is beszélhetünk versenyelőnyről. Ennek a magyarázatát elsősorban a jelentős mértékben megnőtt déligyümölcsimport adja. A kedvezőtlen...

A magyar zöldség-gyümölcs kisárutermelők nagy láncoknak történő értékesítési lehetőségei

Autores: Seres,   Antal; Szabo,   Marton.
A multinacionális láncoknál a közvetlen kisárutermelői beszállítóknak a speciális „réspiaci” termékeknél, illetve a nagy termelők között szabadon hagyott piaci réseken van mozgáslehetőségük. E termékek kivételével a közvetlen kisárutermelői beszállításoknak nincs jövője, mert elaprózott kínálattal nagy számban nem léphetnek be a beszállítói körbe.  Hatékonysági követelmények miatt előbb-utóbb a hazai láncoknál is erősödik a beszerzés koncentrációja, és ez itt is csökkenti a közvetlenül beszállító kisárutermelők ma még lényegesen nagyobb lehetőségeit. A nagy üzletláncok üzletpolitikája olyan követelményeket támaszt, amelyeket a kisárutermelők a réspiaci termékek kivételével külön-külön nem tudnak teljesíteni. Ezért közös termeltető és értékesítő...

A magyarországi baromfiágazat középtávú kilátásai

Autores: Nyars,   Levente.
Magyarország földrajzi fekvése miatt a fehérjeforrások beszerzési költségei magasabbak és a baromfihúsexport is költségesebb a szállítás miatt, de a fűtési és hűtési költségek is magasabbak, mint például Hollandiában, Brazíliában. A globalizáció kihívásai elől a magyar baromfiágazat sem térhet ki. Az árversenyben a nagy kapacitások, az olcsó munkaerő és az olcsó takarmány nagy előnyt jelent. A magyarországi alapanyag-termelés helyzetét nehezíti, hogy a gazdaságok döntő része nem rendelkezik földterülettel, vagyis nem képesek megtermelni a takarmányt, és gondot okoz a keletkezett trágya elhelyezése is. A hazai vágócsirke-termelés középtávon 230 ezer tonna körül alakul. A magas takarmányárak, valamint a „nem-termelő” beruházások költségvonzata miatt a hazai...

A MAGYARORSZÁGI JUHTARTÁS JÖVEDELMEZŐSÉGE

A magyar juhágazat jövedelmi helyzetét 1998-2005 között vizsgálva azt mondhatjuk, hogy az ágazat minden évben veszteséges volt, bruttó jövedelmet két évben, 2001-ben és 2002-ben ért el. A juhtartással foglalkozó gazdálkodók a különféle támogatási lehetőségek maximális kihasználásával az ágazat jövedelmi pozícióján jelentősen javíthatnak. A támogatások igénybevételén túl a jövedel-mezőségi helyzetük javításának forrása a piaci alkalmazkodás, illetve a techno-lógia javítása. Ha a termékeik értékesítési arányát növelnék a karácsonyi sze-zonban a jelenlegi húsvéti értékesítéssel szemben, valamint a kos, illetve a jerke-bárányok értékesítésében a termelők figyelembe vennék azt, hogy jelentősen eltér a két ivar hízlalásának jövedelmezősége az értékesítési súly...

Az állattenyésztési ágazatok kilátásai nem biztatóak a tartósan magas takarmányárak, a vertikálisan kevésbé szervezett, a termékpálya szakaszai közötti laza kapcsolat miatt, ami a legfontosabb felvevőpiacok szervezetlenségére is visszavezethető. A magyarországi állattartók érdemben nem képesek befolyásolni sem a világpiacon, sem az Európai Unió piacán zajló folyamatokat, így kénytelenek a réspiacokat kitöltve alkalmazkodni. Különböző modellváltozataink szerint a szarvasmarha-állomány 680-731 ezer egyed, a tejelőtehén-állomány 266-269 ezer egyed között alakulhat 2013-ban. Továbbra is elsősorban a húshasznú egyedek számának növekedésére lehet számítani. A tejtermelés 2010-ben várhatóan kitölti a nemzeti kvótát. Tej- és tejtermék-kivitelben főként a...

A “masculinização” da produção de leite
Provedor de dados: 31
Autores: Magalhaes,   Reginaldo Sales.
The strengthening of social organizations that made it possible for dairy production to become a market-driven activity has brought about deep changes in the sexual division of labour. The sociological analysis of the changes in family-farming intra-household roles shows that cultural traditions, gender-related power gaps, and social contexts that further deepen differences in market access between men and women are the social and cultural foundations of a hierarchy structured according to sex and generation, where women, especially the youngest, occupy greatly disadvantageous positions. With the strengthening of cooperatives, dairy production began to occupy a rather important role in providing resources to the household, yet the control over the activity...

A mass-balance Ecopath model of Coastal Areas in the Mekong Delta, Vietnam
Provedor de dados: 5
Autores: Van, Mai Viet; Phuong, Nguyen Thanh; Dinh, Tran Dac; Villanueva, Ching-maria; Moreau, Jacques.
A mass-balance Ecopath model of coastal areas in the Mekong Delta has been constructed for a quantitative description of the trophic structure of the ecosystem. The model is used to estimate the important biological parameters and relationships among the different ecologically important groups. The model is based on the data collected from bottom trawling. There are 14 functional groups based on 58 species from coastal areas in the Mekong Delta survey such as shrimps, squids, crabs, mackerel, small pelagics, demersal fishes, benthic feeders, predator fishes and trash fish. The biomass value was estimated from catch production and bottom trawling surveys. Results show that the estimated total biomass of exploited resources was 3.99 ton.km-2. The values of...

A Measurement Quality Factor for Swath Bathymetry Sounders
Provedor de dados: 5
Autores: Lurton, Xavier; Augustin, Jean-marie.
The quality estimation associated with individual soundings measured and computed by swath bathymetry sonars is a paramount issue which is most often imperfectly addressed today by sonar manufacturers. In this paper, a unified definition is proposed for a quality factor usable for all swath bathymetry sonars; the depth-relative error is directly estimated from the signal characteristics used in the sounding computation. The basic algorithms are presented for both phase-difference (oblique incidence) and amplitude (normal incidence) detection, and can be readily implemented in any swath bathymetry system using these detection principles. This approach gives a direct access to the objective bathymetric performance of individual soundings, and hence avoids...

A megújuló energiaforrások szerepe és hatásai a hazai agrárgazdaságban
Provedor de dados: 31
Autores: Magda,   Robert.
Összességében megállapítható, hogy Magyarországon az elmúlt fél évszázadban rendkívül megnőtt az energiafelhasználás, ami többnyire a fosszilis tüzelőanyagokból nyert energiára alapult. Ez arra készteti a jelen és a jövő kor társadalmát, hogy törekedjen a rendelkezésre álló megújuló energiaforrások felhasználásának előtérbe helyezésére, melyek használata a fenntarthatóság és a versenyképesség szempontjából sem elhanyagolható, hiszen ismert, hogy napjaink egyik kritikus költségtényezőjét adják az energiaköltségek. A megoldásban jelentős szerep hárul a vidéki társadalmakra, mert hiába történik az energiafelhasználás zöme az urbanizált területeken, az energia-előállítás, kitermelés a vidékre koncentrálódik. A fosszilis tüzelőanyagok korlátaiból adódóan új...

A meta-analysis of dry matter intake in Nellore and Zebu-crosses cattle
Provedor de dados: 96
Autores: Azevêdo,José Augusto Gomes; Valadares Filho,Sebastião de Campos; Pina,Douglas dos Santos; Chizzotti,Mario Luiz; Valadares,Rilene Ferreira Diniz.
The study was carried out to develop and to evaluate new equations to predict dry matter intake (DMI) of Nellore and Zebu-crosses cattle using meta-analysis procedure. The data used to estimate the parameters were collected from independent performance experiments using growing and fattening Nellore and Zebu-crosses cattle, and they were compiled from 561 experimental units. Before proposing an equation to predict DMI, it was observed that the genetic group was a source of statisticaly significant variation. Therefore, equations to predict dry matter intake in the Zebu-Crosses and Nellore cattle were independently developed. The regression equations for Zebu-crosses cattle were: DMI = -2.6098 + 0.08844BW0.75 + 4.4672ADG - 1.3579ADG2 and DMI = -1.0094 +...

A Metafrontier Analysis of Technical Efficiency of Selected European Agricultures
Provedor de dados: 31
Autores: Barnes,   Andrew Peter; Revoredo-Giha,   Cesar.
Technical efficiency refers to the situation where it is impossible for a firm to produce, with the given know-how, (1) a larger output from the same inputs or (2) the same output with less of one or more inputs without increasing the amount of other inputs. In practice, the interest is on the relative position in terms of efficiency of a particular firm with respect to others. Therefore, technical efficiency is characterised by the relationship between observed production and some ideal or potential production (Greene, 1993). Although the beginning of the efficiency work can be traced to the 1950s (Farrell, 1957), there have been a growing interest on its use in benchmarking performance, predominantly as a means of identifying best practice and improving...

In order to visualize the distribution pattern of the neuronal bodies and neurofibrils in the honeybee brain, we adapted a metallic impregnation technique first described for vertebrate nervous system by Ramón y Cajal. The honeybee brain constitution plays a key role in the development of learning and memory capacities. The general characteristics observed in the honeybee brain, stained by metallic impregnation, revealed its anatomical and morphological constitution in agreement with studies of other insect brains using different techniques. Metallic impregnation evidenced the optic lobe neuropils, the ocelli fiber cells, the neuron extensions of the calyces, and the axon bundles that involve the antennal glomeruli, as well as the neuron extensions in the...

A method for evaluating the extent to which farm subsidies can be de-coupled before profitable arable land is abandoned in the European Union
Provedor de dados: 31
Autores: Fraser,   Rob W.
This paper evaluates concerns over the "abandonment of production" in the context of the recent CAP reform as it applies to the arable sector. The particular focus of the evaluation is on the extent to which the proposed "single farm payment" can be de-coupled from production and yet avoid the abandonment of land on which production is expected to be profitable. An analytical framework is developed which indicates the most important non-policy factors are the profitability of the land, the variability of yield and the grower's degree of risk aversion. The conclusion of a numerical analysis using this framework is that 85% de-coupling is unlikely to lead to abandonment of land in any arable region of the EU, and that 95% de-coupling is also unlikely to lead...

A Methodological Approach to the Spatial Aggregation of Values
Provedor de dados: 31
Autores: Concu,   Giovanni B.; Schilizzi,   Steven.
A Choice Modelling (CM) experiment is developed with the purpose of gaining some insight on how to identify the relevant population for the valuation of an environmental asset. The experiment is based on a survey of Perth residents over the values they attach to Kings Park, the largest urban park in Western Australia, 4/5 of which is native bushland. We design the experiment in order to isolate NUVs form UVs so that trade-offs between attributes of the asset imply tradeoffs between Use Values, Non-Use Values and money. One can then estimate the coefficients for each attribute and analyse the effect of distance on patterns of use. Preliminary results are obtained using data from a pre-survey trial of the questionnaire.

A methodology for definition of rural spaces: an implementation in Brazil
Provedor de dados: 65
Autores: Braga,Gustavo Bastos; Remoaldo,Paula Cristina; Fiúza,Ana Louise de Carvalho.
ABSTRACT: Rural spaces definitions are differentiated in several countries. The Organization for Economic Co-operation and Development (OECD) has standardized a rural definition by regional typology. The OECD regional typology set areas as Predominantly Urban, Intermediate, or Predominantly Rural. This paper analyses the application of OECD regional typology in Brazilian territory. The research used the OECD methodology, with support of GIS software, to define the rural areas in Brazil. The mostly segmented data from Brazilian Census of 2010 are used in contrast to others studies. The paper concludes that Brazil is more urban than official estimates and OECD reports. According to paper results, 87.48% of Brazilian population is urban and only one...

Autores: Molnar,   Andras.
A gazdálkodás ökonómiai kérdéseivel foglalkozók számára a piaci csere híján fontos feladat az externáliák minél szélesebb körű számszerűsítése, mivel csak a társadalom számára jelentkező összes költség és haszon figyelembevételével lehet megítélni a mindenkori agrárpolitikát. Egyre fontosabb az, hogy milyen agrárpolitikai eszközökkel oldhatók meg a liberalizált kereskedelemmel szembeni elvárások és a nem-termék jellegű javak társadalmilag optimális kibocsátása. Ebben a kettős elvárásban a földtulajdon és földhasználat szétválása előnytelen.   -------------------------------------------    In the absence of exchange in the market, researchers into economic aspects of farming place a high emphasis on quantifying externalities to the maximum extent possible....

A globális hőmérséklet-növekedés környezeti változásokhoz, a tengerszint emelkedéséhez, a csapadék mennyiségének és térbeli eloszlásának megváltozásához, szélsőséges időjárási viszonyokhoz vezet. Állat- és növényfajok kipusztulásának sebessége jelentősen nő. Bizonyos betegségek könnyebben elterjedhetnek. E fel¬sorolt hatásokból látható, hogy a mezőgazdaságot közvetlenül érinti a klímaváltozás. Fontos tehát, hogy a mezőgazdasági üzemek maguk is tegyenek a káros hatások enyhítéséért.  Lehetséges megoldás a biomassza tüzelése, amely a mezőgazdasági rendeltetésű épületek és háztartások energiaköltségeit jelentősen mérsékli. Tanulmányunk olyan megoldást dolgoz ki, melyben a hő előállításához szükséges energia költsége teljes mértékben megszűnik, ami energiaerdő...

A számítások rendkívül pozitív képet mutatnak a mezőgazdaság jövedelme-zőségéről 2004-ben, az újonnan csatlakozó országok mindegyikében. A jövede-lemnövekedés hátterében egyrészt a nagyobb átlaghozamok állnak – melyek a rendkívül kedvező időjárási feltételeknek köszönhetők –, másrészt az előző évihez képest mintegy 73%-kal megemelkedett uniós támogatások. - Calculations present an extremely positive picture of agricultural profitability in 2004 in each of the new accession states. In the background to income growth lies greater average yields on the one hand – the result of exceptionally favourable weather conditions – and on the other, the ca. 73% increase in EU subsidies in comparison to the previous year.

A MEZŐGAZDASÁGI JÖVEDELMEK STABILITÁSA
Provedor de dados: 31
Autores: Lamfalusi,   Ibolya.
A mezőgazdasági jövedelmek stabilitásának megteremtése mindenkor az ag-rárpolitika fontos törekvése. A mezőgazdaságból élőknek a termelői jövedelem nagysága és alakulása meghatározza a gazdálkodói életszínvonal minőségét. Az EU országok jövedelemstabilitási mutatóival összevetve a magyar mezőgazda-ságét meg¬állapítható, hogy a hazai gazdálkodók helyzete igen kedvezőtlen. Az ágazatban mind a nominális értéken vett jövedelem stabilitása, mind pedig a jövedelem re¬ál¬értéke kedvezőtlenül alakult. A reáljövedelem 1998 és 2005 között egyetlen évben sem érte el az 1998. évi 80%-át, sőt 2003-ban 50%-nál kevesebb volt.  A mezőgazdasági termelés jövedelemstabilitását a mezőgazdasági kibocsátás kiegyensúlyozottsága határozza meg alapvetően. A kibocsátás már magában...

A magyar mezőgazdaság valós nemzetgazdasági szerepéről többnyire nagyvonalú becsléseken alapuló adatok kerülnek nyilvánosságra. Ezért megkíséreltük, hogy cikkünkben korrekt módszertani alapokon nyugvó, megbízható mutatókat számítsunk az elérhető statisztikai adatok alapján. A mezőgazdaság és a hozzá kapcsolódó ellátó, feldolgozó, forgalmazó tevékenységek (agrobiznisz) jelentőségét a kibocsátás, a bruttó hozzáadott érték és a foglalkoztatottak nemzetgazdasági részarányával jellemeztük. Az ismert tendenciának megfelelően csökkenő részarányokat találtunk, amelyek ráadásul szerényebbek is, mint a szakmai köztudatban szereplő értékek. Ennek ellenére tévedés lenne a mezőgazdaság, illetve az agrobiznisz jelentéktelenné válásáról beszélni (még pusztán gazdasági,...

A mezőgazdasági termelők motivációi az állati termékek előállításában
Provedor de dados: 31
Autores: Beladi,   Katalin; Kertesz,   Robert; Dudas,   Gyula.
A magyar állattenyésztés helyzete 2004 óta is folyamatosan romlik. A mezőgaz¬dasági kibocsátásból való részesedése több év óta 37-38 százalék körül stagnál, az állatállomány csökken. Mindez szorosan összefügg azzal, hogy a fontosabb ágazatok jövedelemhelyzete bizonytalan, és az évek közötti hullámzása is jelentős. A felvásárlási árak gyakran nem fedezik a termékek költségeit, és csak az állami támogatásokkal jutnak minimális nyereséghez a gazdaságok. Az átlagos értékek hátterében eltérő termelési színvonalon gazdálkodó vállalkozások húzódnak meg: versenyképesen és jövedelmezően termelők, és az eseményekkel sodródó, többnyire veszteségesen ter¬melők. Főleg ez utóbbiakkal kapcsolatban jogosan merül fel a kérdés, hogy vajon mi motiválja tevékenységüket? Az...

A tanulmány alapvető célja az, hogy hozzájáruljon az érzékenység, sérülékenység és adaptációs képesség vizsgálatának módszertanához. A kutatások eredményei felhívják a figyelmet arra, hogy bár az európai vidék összessége egyre sérülékenyebbé válik a különböző globális kihívásokra, a veszélyeztetettség mértéke régiónként eltérő. A kutatások eredményei megerősítették az IPCC 3. jelentésében megfogalmazott hipotéziseket, melyek szerint a gazdag országok ugyanolyan veszélyeztetettség mellett is kevésbé sérülékenyek, mivel nagyobb az alkalmazkodóképességük. A klímaváltozás, amely pozitív és negatív hatást is gyakorol Európa mezőgazdaságára, módosítja az eddigi komparatív előnyöket, illetve hátrányokat.

A mezőgazdasági üzem fogalmának agrárjogi értelmezése
Provedor de dados: 31
Autores: Orlovits,   Zsolt.
Az agrárüzem definiálása nemcsak a közgazdaságtan, hanem az agrárjog szempontjából is számos problémát vet fel. Szakmai körökben keveredik a mezőgazdasági üzem dologösszességkénti, illetve szervezeti forma szerinti megkülönböztetése. Az uniós jog ezzel szemben a mezőgazdasági üzemet önálló jogi kategóriának tekinti és épít arra, hogy a tagországok egységes üzemszabályozási törvényben állapítják meg a nemzeti agrárüzemek működtetésének jogi-közigazgatási kereteit. Ez a feltételezés azonban csak az Európai Unió nyugat-európai tagállamaira igaz. Bár egyes üzemszabályozási elemek a magyar jogban is megtalálhatók, azok nem az agrárüzemre mint absztrakt jogi kategóriára, hanem a mezőgazdasági vállalkozások egyes konkrét szervezeti formáira vonatkoznak.

A mezőgazdasági üzem fogalmának változása

A köznyelvben üzemnek nevezik azt a helyet, épületet, melyben valamilyen gazdasági egység tevékenykedik, illetve valamilyen termelő tevékenységet folytatnak. Az EU tanácsi és bizottsági jogrendszere viszont az üzemet az üzemtulajdonosok által igazgatott termelőegységként definiálja. Az angolszász országokban a farm elnevezést használják, amely bármilyen típusú mezőgazdasági üzem, vállalat lehet (family farm: családi gazdaság, cooperative farm: mezőgazdasági szövetkezet, large-scale farm: nagyüzem, small-scale farm: kisüzem stb.). Véleményünk szerint az üzem fogalma alatt magát a gazdálkodó egységet célszerű érteni, függetlenül annak jogi formájától, méretétől. Az üzem mellett szinonim fogalomként lehet alkalmazni a gazdaság, vagy a mezőgazdasági...

A vizsgált vállalkozásokban a likviditási gyorsráta, a saját tőke aránya és az eladósodottság mutatószámainak figyelemmel kísérése a fizetésképtelenség elkerülését segíthette volna. Megállapítható továbbá, hogy alacsony saját tőkével a mezőgazdasági termelés hosszú távon nem folytatható, ezért szükséges, hogy a befektetők a termelés jellegének megfelelő jegyzett tőkével alapítsanak vállalkozást, mert a hitelek felvétele nem pótolja,...

A Microeconomic Model for Subsidies Allocation:  the Case of Belarus
Provedor de dados: 31
Autores: Svetlov,   Nikolai M.; Kazakevich,   Iryna A.
The paper develops a microeconomic methodological framework that allows approaching subsidy allocation across the types of assets and impact of subsidies on agricultural outputs and profits. The methodology is based on a non-parametric production frontier estimation. The empirical application is made to 1084 Belarusian corporate farms. The results suggest targeting governmental support at grain and milk production. In this case, 4.14 trillion Belarusian roubles of subsidies increase the overall profit of the sample farms by 1.46 trillion. In the case of targeting, the farms with higher overall efficiency are more sensitive to the support and are able to absorb larger amount of subsidies. The opposite is true in the absence of targeting.

O eucalipto é o gênero florestal mais pesquisado em micropropagação, entretanto, são poucos os resultados efetivos obtidos com sua multiplicação contínua. A micropropagação inclui a desinfestação e cultivo dos explantes em meio nutritivo e condições assépticas, a multiplicação dos propágulos em sucessivos subcultivos e o enraizamento in vitro ou ex vitro. Como vantagens, possibilita: alto rendimento por planta matriz; obtenção de plantas isentas de viroses; produção de mudas em qualquer época do ano; produção intensiva de mudas sadias, em curto período de tempo e espaço reduzido; clonagem de plantas de difícil propagação vegetativa por métodos convencionais como estaquia e miniestaquia; e preservação de plantas matrizes sem riscos de infecção.

A MINŐSÉG A MAGYAR HÚSIPAR VERSENYKÉPESSÉGÉBEN

Autores: Nagy-Percsi,   Kinga.
A tanulmány elkészítésének alapját az engedélyezett, illetve a jóváhagyott és derogációs húsüzemek körében 2005. év végén és 2006. év elején elkészített kér-dőíves felmérés adta. A márkázott húsprogramok fő problémáját leginkább a márkázott termékek iránti hazai fizetőképes kereslet hiányában látják. Ettől kis mértékben marad el a programokhoz kapcsolódó elégtelen promóció, ami kiemeli az összefogás, a közösen végzett promóció szükségességét a versenyképesség növelése érdekében. A multinacionális láncok árleszorító törekvései és a növekvő költségek hatá-sára kialakult kisebb jövedelemtermelő képességet a húsipari cégek részben a beruházások visszafogásával ellensúlyozzák, mégpedig azokon a területeken, me-lyek nem kifejezetten az előírásoknak...

A vizsgálatok alapján megállapítható, hogy a magyar baromfi-feldolgozó iparág megfelelően teljesíti mind a hazai, mind az EU-s előírásokat, követelményeket. Az élelmiszerbiztonsági előírásoknak való megfelelés valamennyi érintett vállalkozásban elsődleges szempont. A magas minőségi színvonal elérésére és teljesítésére irányuló további módszereket, mint pl. az integrált menedzsment irányítási rendszereket is alkalmazzák a vállalkozások, de az ezekre való törekvést nem a vállalat belső igénye, hanem a piac indukálja. Remélhetőleg a jövőben egyre több élelmiszeripari vállalkozás ismeri fel az ISO 22000 szabvány alkalmazásának előnyeit, ami ötvözi a HACCP és az ISO 9001 alkalmazását, és kifejezetten az élelmiszeripari termelésre specializált szabványként...

A model for coupled electro-hydro-mechanical processes in fine grained soils accounting for gas generation and transport
Provedor de dados: 42
Autores: Tamagnini,Claudio; Jommi,Cristina; Cattaneo,Fabio.
A theoretical and numerical model is developed for the quantitative analysis of coupled processes taking place in active waste containment systems, such as electrokinetic barriers or fences, in which alow intensity DC current is circulated across the clay barrier to move polar and non-polar contaminants. A novel feature of the proposed approach is the allowance for the presence of air in the pore space. Under unsaturated conditions, all transport coefficients involved in the electrokinetic process are strongly dependent on the degree of saturation of pore liquid. In order to assess the predictive capability of the proposed theory and to appreciate the impact of gas production at the electrodes, a series of numerical simulations of simple onedimensional...

A Model for the Estimation of Personal Stature from the Length of Forearm
Provedor de dados: 77
Autores: Ilayperuma,Isurani; Nanayakkara,Ganananda; Palahepitiya,Nadeeka.
Prediction of stature from incomplete and decomposing skeletal remains is vital in establishing the identity of an unknown individual. It has been stated that a variety of factors such as race, gender and nutrition play an important role in determining the height of an individual. Estimation of stature from measurements of various long bones has been achieved with varying degree of accuracy. Those studies resulted in establishing different formulae for the estimation of stature for the respective populations. However, evidence shows that there is a great void in such norms for Sri Lankans. Hence, this study was designed to investigate the relationship and to propose a gender and age specific linear regression models between the ulna length and height of an...

A Model of Endogenous Market Structure, Innovation, and Licensing in Agricultural Biotechnology
Provedor de dados: 31
Autores: Anderson,   Benjamin; Sheldon,   Ian M.
We develop a model of endogenous market structure and sunk cost R&amp;D investment that allows for the licensing of technology among competitors. Our theoretical model predicts both a greater lower bound to market concentration and higher levels of quality compared to the case without licensing. These result simply that in markets in which licensing and a symmetric R&amp;D costs are prevalent, such as the agricultural biotechnology sector, the ability to license technology generates more concentration among firms but also improves consumer welfare by incentivizing the production of higher quality.

A MODEL OF THE ECONOMIC IMPACT OF AFRICAN HORSE SICKNESS TO THE EQUINE BREEDING INDUSTRY IN SOUTH AFRICA
Provedor de dados: 31
Autores: Brooks,   Laura.
A deterministic model for the economic impact of African Horse Sickness (AHS) on the equine breeding industry was developed for South Africa. It was applied to the case of the 2007/2008 outbreak of AHS in the Eastern Cape as a pilot application of the model, using data from breeders in the province. It was concluded that the deterministic model’s extension to include other areas of equine livelihoods could be effective in exposing the need for further research into the control and treatment of AHS in South Africa.

A model-based approach to moral hazard in food chains - What contribution do principal-agent-models make to the understanding of food risks induced by opportunistic behaviour?
Provedor de dados: 31
Autores: Hirschauer,   Norbert.
Food risks may be caused by moral hazard, i.e. by opportunistic behaviour of upstream sellers who exploit the fact that many food product qualities remain uncertain to downstream buyers in the course of conventional market transactions (credence qualities). Due to this lack of market transparency buyers run the risk to pay premium prices for inferior products (quality risks); furthermore, they run the risk to use or consume substances which are harmful (health risks). Therefore, they will want to design optimal contracts and controls preventing opportunistic behaviour. Usually, however, buyers cannot contract contingent on the actions of upstream sellers because they cannot observe them directly (information asymmetry). Motivated by the obviously...

Autores: Hamard, Alice; Mazurais, David; Boudry, Gaelle; Le Huerou-luron, Isabelle; Seve, Bernard; Le Floc'H, Nathalie.
High dietary threonine extraction by the digestive tract suggests that threonine contributes to maintain gut physiology. In the present study, we evaluated the impact of a low (6.5 g of threonine/kg diet; LT group) or a control well-balanced threonine diet (9.3 g of threonine/kg diet; C group) given to piglets for 2 weeks on ileal permeability and Na+-dependant glucose absorption capacity in Ussing chambers. The paracellular permeability was significantly increased in the ileum of LT compared to C piglets (P=.017). The Na+-dependent glucose absorption capacity showed a nonsignificant increase in the LT piglets. In addition, we analysed ileal gene expression profiles in the LT and C groups using porcine multitissue cDNA microarrays. Compared to the C...

A modified Arcan test to analyze the behavior of composites and their assemblies under out-of-plane loadings
Provedor de dados: 5
Autores: Cognard, J. Y.; Sohier, L.; Davies, Peter.
Composite materials are a key element in weight reduction strategies, so the analysis of the mechanical behavior of assemblies of composite modules is of great importance. Failure initiation in bonded assemblies involving composites is often associated with crack initiation in the adhesive or delamination of the composite plies close to the adhesive joint, caused by interlaminar or through-thickness stresses. Thus, the analysis of the behavior of composites and their assemblies under out-of-plane loadings is necessary in order to optimize such structures. However, few experimental devices are proposed in the literature and they often require thick composite specimens which are not representative of most industrial applications. This paper describes the use...

A Modified phosphate-carrier protein theory is proposed as a non-target site mechanism For glyphosate resistance in weeds
Provedor de dados: 87
Autores: Roso,A.C.; Vidal,R.A.
Glyphosate is an herbicide that inhibits the enzyme 5-enolpyruvyl-shikimate-3-phosphate synthase (EPSPs) (EC 2.5.1.19). EPSPs is the sixth enzyme of the shikimate pathway, by which plants synthesize the aromatic amino acids phenylalanine, tyrosine, and tryptophan and many compounds used in secondary metabolism pathways. About fifteen years ago it was hypothesized that it was unlikely weeds would evolve resistance to this herbicide because of the limited degree of glyphosate metabolism observed in plants, the low resistance level attained to EPSPs gene overexpression, and because of the lower fitness in plants with an altered EPSPs enzyme. However, today 20 weed species have been described with glyphosate resistant biotypes that are found in all five...

A Molecular Perspective On The Diversification Of Short-Tailed Opossums (Monodelphis: Didelphidae)
Provedor de dados: 81
Autores: Solari,Sergio.
As currently understood Monodelphis includes more than 22 species and is the most diverse genus of opossums (Didelphimorphia). No complete evaluation of the systematic relationships of its species has been attempted, despite the fact that several species groups and even genus-level groups have been proposed based on morphology, and that some of them are limited to recognized biogeographic regions. Here, genealogic relationships among 17 species were assessed based on phylogenetic analyses of 60 individual sequences (801 base pairs of the mitochondrial cytochrome b gene). The analyses cast doubts on the monophyly of Monodelphis, but species were consistently discriminated into eight species groups: (a) brevicaudata group, with five species, (b) adusta...

A Multi-Criteria Decision Framework for Animal Welfare Policy
Provedor de dados: 31
Autores: Hellstrom,   J.; Bicknell,   Kathryn.
Policy decisions aimed at improving farm animal welfare involve balancing several competing objectives. Not only do such decisions involve tradeoffs between social, ethical, economic and welfare considerations, animal welfare itself is a multi-dimensional concept and some husbandry practices may satisfy some welfare needs but fail to satisfy others. Multi-criteria decision analysis is a decision theoretic tool that has been used to inform decision making in fields such as environmental policy, urban and regional planning, and biosecurity – all of which are characterised by competing goals and multiple stake-holders. This paper presents a preliminary multi-criteria framework for the analysis of animal welfare policies at the national level using indoor...

Autores: Ritten,   John P.; Frasier,   W. Marshall; Bastian,   Christopher T.; Paisley,   Steven I.; Smith,   Michael A.; Mooney,   Sian.
Many areas of the US recently endured a severe drought and management strategies to cope with the lack of forage production varied. A multi-period mathematical model is presented that estimates the outcomes of two common producer responses to changes in precipitation, partial liquidation and purchasing hay, given fluctuating cattle prices over a long term planning horizon. Results were further summarized with regression analysis and selected elasticities were calculated to reflect the sensitivity of outcomes to variability in precipitation and livestock prices. Although little impact was seen from utilizing additional hay as a strategy during drought, producers who follow this strategy are in a position to market more animals immediately post drought in...

A multi-regional general equilibrium model to assess policy effects at regional level
Provedor de dados: 31
Autores: Lovo,   Stefania; Magnani,   Riccardo; Perali,   Carlo Federico.
In this paper we develop a multi-regional general equilibrium model (MEG-R) to compare the social desirability of the CAP reform in the three Italian macro-regions: North, Center and South. The model employs a mixed complementary framework that allows for the decision of not producing a particular crop in one or more regions and presents an attempt to model interregional trade flows. The model incorporates the links between production and consumption that characterize farm household’s behavior and allows for heterogeneous household responses across regions. Results show a general tendency to reallocations from cereal crops to forage that appear more severe in the South. In this region, the reduction in crops cannot be translated into an effective expansion...

Multivariate statistical methods are relatively new tools for data analysis. They have a lot of applications in biological researches: nevertheless, for several reasons, they have not been widely employed in this subject yet. Recently, present authors published a paper applying multivariate statistics on non-parasitic phase of Anocentor nitens. In the present article Boophilus microplus has received a very similar statistic treatment. In this paper, the influence of different incubation conditions was studied in groups of 12-15 individuals in each of the 24 combinations of six temperatures 24, 27, 30, 32, 34 and 36ºC and four relative humidity values, 100, 80, 75.5 and 70% over the cycle variables of B. microplus.

A multivariate analysis of taxonomic limits in Diplolaemus Bell 1843
Provedor de dados: 72
Autores: Victoriano,Pedro F; Coronado,Tanía M; Ortiz,Juan Carlos.
The gemís Diplolaemus Bell, 1843 is a common squamate component of the Patagonian región of South América. Considerable taxonomic confusión exists within this gemís, particularly about the status of Chilean-Andean populations and the actual distribution of D. leopardinas (Werner, 1898). In an attempt to clarify the taxonomic status and distribution of Diplolaemus species, we performed a principal component analysis (PCA) and discriminant function analysis (DFA) using both standard morphometric and meristic data. Multivariate summaries of morphometric data show that most species are poorly discriminated, with the exception of D. darwinii. In contrast, a PCA analyses performed on the meristic data clearly distinguish three discrete groups: 1. D. darwinii, 2....

A new approach for obtaining rapid uniformity in rice (Oryza sativa L.) via a 3x x 2x cross
Provedor de dados: 74
Autores: Xing,Shaochen; Cai,Yuhong; Zhou,Kaida.
A triploid (2n = 3x = 36) rice plant was obtained by screening a twin seedling population in which each seed germinated to two or three sprouts that were then crossed with diploid plants. One diploid plant was chosen among the various F1 progenies and developed into an F2 population via self-pollination. Compared with the control variety Shanyou 63, this F2 population had a stable agronomical performance in field trials, as confirmed by the F-test. The stability of the F2 population was further substantiated by molecular analysis with simple sequence repeat markers. Specifically, of 160 markers assayed, 37 (covering all 12 chromosomes) were polymorphic between the parental lines. Testing the F1 hybrid individually with these markers showed that each PCR...

To ensure that LFIs do not default on either their deposits or their derivative contracts, we require that they maintain an equity cushion sufficiently great that their own credit default swap price stays below a threshold level, and a cushion of long term bonds sufficiently large that, even if the equity is wiped out, the systemically relevant obligations are safe. If the CDS price goes above the threshold, the LFI regulator forces the LFI to issue equity until the CDS price moves back down. If this does not happen within a predetermined period of time, the regulator intervenes. We show...

Cold-water coral (CWC) habitats can form complex structures which provide refuge, nursery grounds and physical support for a diversity of other living organisms, but despite their ecological significance, CWCs are still vulnerable to human pressures such as fishing, pollution, ocean acidification and global warming Providing coherent and representative conservation of vulnerable marine ecosystems including CWCs is one of the aims of the Marine Protected Areas networks being implemented across European seas and oceans under the EC Habitats Directive, the Marine Strategy Framework Directive and the OSPAR Convention. In order to adequately represent ecosystem diversity these initiatives require a standardised habitat classification that organises the variety...

A new dark-saddled species of Hypostomus (Siluriformes: Loricariidae) from the upper rio Paraguay basin
Provedor de dados: 83
Autores: Zawadzki,Cláudio Henrique; Weber,Claude; Pavanelli,Carla Simone.
A new Hypostomus species is described from the rio Cuiabá, upper rio Paraguay basin, Mato Grosso State, Brazil. The new species is distinguished from all other Hypostomus species, with exception of young specimens of H. latifrons, by the presence of a wide dark transverse bars on laterals of body and fins; and conspicuous dark vermiculations on abdominal region. From H. latifrons it differs by having just one pre-dorsal plate surrounding supraoccipital bone and by the maintenance of the dark saddles in adults. Added to the other fish species recently described from the upper rio Paraguay basin, this work helps to highlight that the region still functions as a potential source of new species.

A new functional role for lateral inhibition in the striatum: Pavlovian conditioning
Provedor de dados: 17
Autores: Patrick Connor; Thomas Trappenberg.
The striatum has long been implicated in reinforcement learning and has been suggested by several neurophysiological studies as the substrate for encoding the reward value of stimuli. Reward prediction error (RPE) has been used in several basal ganglia models as the underlying learning signal, which leads to Pavlovian conditioning abilities that can be simulated by the Rescorla-Wagner model.&amp;#xd;&amp;#xa;&amp;#xd;&amp;#xa;Lateral inhibition between striatal projection neurons was once thought to have a winner-take-all function, useful in selecting between possible actions. However, it has been noted that the necessary reciprocal connections for this interpretation are too few, and the relative strength of these synaptic connections is weak. Still,...

A new generation of Tropical Cyclone Size measurements from space
Provedor de dados: 5

Combined microwave brightness temperature measurements from recent L- and dual C-band satellite radiometers provide new estimates of surface wind speed structure in Tropical Cyclones which enhances temporal sampling capability for gale (34-knots), damaging (50-knots) and destructive (64-knots) wind radii.  Wind radii estimates in Tropical Cyclones (TC) are crucial to help determine the TC wind structure for the production of effective warnings and to constrain initial conditions for a number of applications. In that context, we report on the capabilities of a new generation of satellite microwave radiometers operating at L-band frequency (~1.4 GHz) and dual C-band (~6.9 and 7.3 GHz). These radiometers provide wide swath (&gt; 1000 km) coverage at a spatial...

A new genus and species of Heroini (Perciformes: Cichlidae) from the early Eocene of southern South America
Provedor de dados: 83
Autores: Perez,Patricia Alano; Malabarba,Maria Claudia; del Papa,Cecilia.
The Lumbrera Formation is the uppermost unit of the Salta Group, which crops out in northwestern Argentina. The paleoenvironment of the Lumbrera Formation is interpreted as a perennial lake deposited under temperate climatic conditions during the early to middle Eocene. Its fossil content is made up of palynomorphs, insects, crocodiles, turtles, lizards, and mammals, besides an ichthyofauna formed by cichlids, poeciliids and dipnoans. †Plesioheros chauliodus is described based on a single individual from this formation, which was fossilized as a lateral view impression (missing anal and caudal fins). It can be distinguished from other cichlids by a moderately deep body, enlarged anterior dentary teeth bearing subapical cusp, a low abdominal vertebral count...

Autores: García,Nayla; Morffe,Jans.
A new genus and two new species of xustrostomatids (Nematoda: Xustrostomatidae) are described parasitizing diplopods from the West Indies. Trachyglossoides jimenoi gen. nov. sp. nov. from Cuba, is similar to Trachyglossus Hunt, 2002. It differs by having the female genital tract monodelphic, feature unique in the family. This constitutes the second record of the family from the country. Zalophora dominicana sp. nov. from the Dominican Republic resembles Z. repentina García &amp; Morffe, 2010. It can be segregate by having a minor development of the cephalic crests and the cephalic end barely inflated. This constitutes the first record of the family and genus for the Dominican Republic.

Autores: Lucena,Antônio Edson de Souza; Sampaio,Divaldo de Almeida; Silva,Ednaldo Rosas da; Paiva,Virgínia Florêncio de; Santiago,Ana Cláudia; Leite,Ana Cristina Lima.
Highly purified intravenous immunoglobulin G concentrate (IV IgG) was produced with the use of polyethylene glycol associated to a single-stage precipitation by ethanol, instead of the classic Cohn-Oncley process, which employs cold alcohol as the precipitating agent, in a three-stage process. Precipitation of crude fraction containing more than 95% of immunoglobulin G was performed by liquid chromatography with a cation exchanger, CM-Sepharose, as a stationary phase. During the process, the product was subjected to two-stage viral inactivation. The first stage was performed by the action of sodium caprylate, 30 mM at pH 5.1+/- 0.1, and the second stage was performed by the action of a solvent-detergent mixture. The finished product was formulated at 5%...

Carioca Lake is located within the limits of the Rio Doce State Park, in the eastern part of the state of Minas Gerais. This park, one of the largest natural reserves of the Atlantic Rain Forest in Brazil, is a hotspot of tropical biodiversity. The purpose of this study was to update existing information on the bathymetry and morphometric features of the lake, using differential GPS (DGPS) technology for data collection, coupled to a digital echo sounder. The bathymetry was based on the acquisition of 1106 points, where the depths as well as the geographic coordinates were obtained. The new study allowed the refinement of existing primary and secondary morphometric data for this lake.

Autores: Meireles,Ana Célia Maia; Andrade,Eunice Maia de; Chaves,Luiz Carlos Guerreiro; Frischkorn,Horst; Crisostomo,Lindbergue Araujo.
A study on surface water quality in the Acaraú Basin, in the North of the state of Ceará, Brazil was performed. Qualitative dynamics of water flowing to the Acaraú River that supplies water to the irrigation project in the area was evaluated. Multivariate Factor Analysis/Principal Component Analysis was used for evaluation of water quality in order to develop a water quality index (WQI) that reflects soil salinity and sodicity risks and water toxicity to plants. From April/2003 to September/2005 water were sampled from ten sampling sites covering the basin, where physical and chemical parameters that contribute to the WQI were evaluated. The results showed that the use of water for irrigation in the Acaraú basin, according to the proposed WQI, are...

'Achatina vassei Germain', 1918, of which so far only the holotype is known (figured), is now recorded from Gorongosa National Park in Mozambique (Sofala Province) north of the road Beira-Mtare (Zimbabwe). The systematic position is still unclear because of the lack of anatomical data; this taxon is probably a restricted-range species centred on the plateau of Central Mozambique. A list of the terrestrial molluscs of the ‘Greater Gorongosa Ecosystem’ from the literature and specimens in the Leiden Museum is added; Curvella whytei E.A. Smith, 1899, is recorded as new for Mozambique.

A new species of Demidospermus Suriano, 1983 is described from the gills of Auchenipterus osteomystax Miranda-Ribeiro, 1918 (Auchenipteridae), collected in the upper Paraná river floodplain, Brazil. The gills were removed and preserved in 5% formalin. Later the parasites were removed from the gills with the aid of a stereomicroscope and conserved in 70% alcohol. Some specimens were stained with Gomori’s trichrome, dehydrated in absolute alcohol and cleared with faia creosote to observe the internal organs. Other specimens were mounted in Hoyer’s medium for the study of the sclerotized structures. The present study describes a new monogenetic species, Demidospermus osteomystax n. sp., characterized by: tandem gonads; V-shaped haptoral bars with...

Provedor de dados: 103
Autores: Knoff,Marcelo; Fernandes,Berenice M. M.
Tormopsolus brasiliensis sp. nov. is described from the intestine of Genypterus brasiliensis Regan, 1903, from Brazil. The new species is characterized mainly by having an almost square terminal oral sucker, a pharynx of the same size or larger than the oral sucker, and testes very close to each other and without vitelline follicles between them. Tormopsolus brasiliensis sp. nov. is most closely related to T. lintoni Caballero, 1952, sharing with the latter the space between the gonads and the distribution of the vitelline fields. It differs from that species by the lack of a space between the gonads and the absence of vitelline follicles between the testes; by the smaller distance between the oral and ventral suckers; by the presence of a wide ejaculatory...

A new starting point for the South and Equatorial Atlantic Ocean
Provedor de dados: 5
Autores: Moulin, Maryline; Aslanian, Daniel; Unternehr, Patrick.
The opening of the Equatorial and South Atlantic Oceans is still a matter of debate, particularly as concerns the locations of the intraplate deformation. We propose here a critical review of the kinematic models published since Bullard et al., 1965, based on a series of constraints: new interpretation of the magnetic anomalies, seafloor isochrons, flow lines, fracture zones, continental and oceanic homologous structures and radiometric dating of igneous rocks. All of these models present numerous unexplained misfits (gaps, overlaps and misalignments). We present here a new evolution of the Equatorial and South Atlantic Ocean from the tightest reconstruction to Chron C34. This new model confirms the hypothesis of a northward propagation of the South...

Based on new knowledge coming from marine perciform species, the origin of oocytes and their development in the Ostariophysi, Gymnotus sylvius is described. In both Gymnotus sylvius and marine perciform fish, oogonia are found in the germinal epithelium that forms the surface of the ovarian lamellae. At the commencement of folliculogenesis, proliferation of oogonia and their entrance into meiosis gives rise to germ cell nests that extend into the stroma from the germinal epithelium. Both cell nests and the germinal epithelium are supported by the same basement membrane that separates them from the stroma. At the time of meiotic arrest, oocytes in a cell nest become separated one from the other as processes of prefollicle cells, these being derived from...

A Nonlinear Generalized Additive Error Model of Production and Cost
Provedor de dados: 31
Autores: Paris,   Quirino; Caputo,   Michael R.
In 1944, Marschak and Andrews published a seminal paper on how to obtain consistent estimates of a production technology. The original formulation of the econometric model regarded the joint estimation of the production function together with the first-order necessary conditions for profit-maximizing behavior. In the seventies, with the advent of econometric duality, the preference seemed to have shifted to a dual approach. Recently, however, Mundlak resurrected the primal-versus-dual debate with a provocative paper titled “Production Function Estimation: Reviving the Primal.” In that paper, the author asserts that the dual estimator, unlike the primal approach, is not efficient because it fails to utilize all the available information. In this paper we...

A Nonparametric Approach to The Analysis of HACCP/RMP Implementation Process
Provedor de dados: 31
Autores: Cao,   Kay; Scrimgeour,   Frank G.
In this paper we conduct an analysis of the implementation of HACCP/RMP in the NZ Meat Industry based on the data collected from our recent survey. Nonparametric methods are used to measure the association between plant characteristics such as size, age, activities, and food safety management practices and HACCP/RMP adoption motivations, implementation problems, benefits, and costs. Results give insights into the ongoing process of mandatory RMP in New Zealand.

Next generation sequencing (NGS) are these days one of the key technologies in biology. NGS&amp;#x27; cost effectiveness and capability of finding the smallest variations in the genome makes them increasingly popular. For studies aiming at genome assembly, differences in read count statistics do not affect the outcome. However, these differences bias the outcome if the goal is to identify structural DNA characteristics like copy number variations (CNVs). Thus a normalization step must removed such random read count variations subsequently read counts from different experiments are comparable.

A Note on Measures of Single Timeseries Activity in Resting-State fMRI Studies
Provedor de dados: 17
Autores: Xi-Nian Zuo.
In statistics, signal processing and mathematical finance, a time series  is a sequence of data points, measured typically at successive times spaced at uniform time intervals. Here, I only focus on the discrete time series. The motivation of writing this methodology note is to clarify the relationship between the measures to quantify activity of an observed timeseries. Particularly, focus one several measures used in recently emerged field of resting-state fMRI studies. Although all these measures have been extensively developed in EEG or other timeseries studies, many researchers focusing on various applications in or new comers to this new field need to know existed measures and the relationships among these measures.

A note on stamen position and petal number in Loranthaceae
Provedor de dados: 16
Autores: Kuijt, J.
Stamen position in Loranthaceae is summarized in both the Old and New Worlds. In the former, stamens are inserted on petals at the same height in an individual flower, with very few exceptions that appear to be in basalmost genera only. In the Americas, much diversity exists in both the position and the within-flower shapes of stamens, phenomena that occur in many genera, Psittacanthus showing the greatest diversity. The dimorphic, or at least the biseriate condition is believed to be the plesiomorphic state. Some comments are added on petal numbers in the family.

Autores: Nivievskyi,   Oleg; Brümmer,   Bernhard; von Cramon-Taubadel,   Stephan.
‘Productivity and efficiency growth enhances competitiveness’. Similarly formulated statements are common in the literature on the economic performance of firms, industries and nations. This conventional perception in the economic literature, originating from trade and growth theory models, however, lacks a clearly defined mathematical formulation. Earlier work by Page (1980) and Nishimizu and Page (1986) provides an elegant formalization of the relationship between the productivity growth and competitiveness measured by the Domestic Resource Costs (DRC) ratio. However, the relationship between technical efficiency and competitiveness has not been addressed in the literature. Moreover, the DRC is a biased measure of competitiveness. We propose static and...

The recently published Altai fossil sequence from Denisova Cave was purported to be so different from anatomically modern humans, yet have the physiological landmarks of that species designation. When the published sequence was examined it was found that segments in the mtDNA hypervariable regions could be found to align with that of anatomically modern humans if one introduced an insertion at a position found in Neanderthals. Some other points of interest arise from a reconsideration of the sequences for other published samples and Neanderthals from the same perspective.

A Novel Adoption Index of Selected Agricultural Technologies: Linkages with Infrastructure and Productivity
Provedor de dados: 31
Autores: Jain,   Rajni; Arora,   Alka; Raju,   S.S.
Variations in agricultural productivity in different states across the country are mainly due to large differences in the level of adoption of selected agricultural technologies and the underlying determinants of adoption of these technologies. Agricultural technologies selected in this paper include high-yielding varieties of seeds, chemical fertilizers, pesticides, use of machinery, etc. The pattern of adoption has been examined across the country based on the 54th round of NSSO dataset. The quantification of adoption has been carried out for each state in the form of a novel ‘adoption index’. The relation between adoption index and status of the infrastructure in the corresponding state has been examined. The strong correlation between adoption index...

A novel mathematical tool for generating highly conserved protein domain via different organismal genomic landscapes
Provedor de dados: 17
Autores: Arunava Goswami; Pabitra Pal Choudhury; Rajneesh Singh; Sk. Sarif Hassan.
Darwinian evolution hypothesizes that a short stretch of DNA was first constructed and then it expanded to give rise to a long strand. This long strand then produced a mix of exons, introns and repetitive DNA sequence. The order of production of above three kinds of DNA sequence is unknown. Reshuffling of stretches of DNA like above within organisms has given rise to different chromosomes. Till date it is not known how this process is governed. In this paper we show that starting with a sixteen base-pair human olfactory DNA sequence one can form a highly conserved protein domain. Once this domain is formed repetitive DNA sequences of a particular kind starts generating which signifies that this particular conserved protein domain will be unique in nature....

A Numerical Analysis of Optimal Extraction and Trade of Oil under Climate Policy
Provedor de dados: 31
Autores: Massetti,   Emanuele; Sferra,   Fabio.
We introduce endogenous investments for increasing conventional and non-conventional oil extraction capacity in the integrated assessment model WITCH. The international price of oil emerges as the Nash equilibrium of a non-cooperative game. When carbon emissions are not constrained, oil is used throughout the century, with unconventional oil taking over conventional oil from mid-century onward. When carbon emissions are constrained, oil consumption drops dramatically and the oil price is lower than in the BaU. Unconventional oil is not extracted. Regional imbalances in the distribution of stabilisation costs are magnified and the oil-exporting countries bear, on average, costs three times larger than in previous estimates.

A Partial Budget Approach to Estimating Cash Rents
Provedor de dados: 31
Autores: Ibendahl,   Gregory A.
Because of the extra risk, tenants who cash lease land should earn more money than those tenants with share leases. A competitive land market and the need to support bigger and newer machinery can easily lead tenants to pay more than they should for a cash lease. Share leases tend to avoid the overpayment problem as the share percentage is usually relatively fixed. Since share leases are not always available, this paper presents a way for tenants to determine if a cash lease rate is reasonable for the area by using a partial budget approach that compares lease types.

This work illustrates the preliminary findings of a participatory research process aimed at identifying responses for sustainable water management in a climate change perspective, in two river basins in Europe and Asia. The paper describes the methodology implemented through local workshops, aimed at eliciting and evaluating possible responses to flood risk. Participatory workshops allowed for the identification of four categories of possible responses and a set of nine evaluation criteria, three for each of the three pillars of sustainable development. The main outcome of such activities consists in the ranking of broad response categories instrumental to the objective of the Brahmatwinn research project, i.e. the identification of Integrated Water...

A partnership between science and industry for a monitoring of anchovy &amp; sardine in the Bay of Biscay: When fishermen are actors of science
Provedor de dados: 5
Autores: Masse, Jacques; Sanchez, Florence; Delaunay, Damien; Robert, J. M.; Petitgas, Pierre.
Anchovy and sardine are small pelagic species occupying similar geographic areas in the Bay of Biscay (North-East Atlantic). Their biomass is strongly dependent on recruitment, making the annual assessment of TAC (Total Allowable Catch) a risky strategy due to uncertainty in predicting the magnitude of recruitment. Monitoring these resources more often and throughout their life cycle could allow management strategies to be adjusted based on observations which indicate the level of recruitment. In order to achieve a more frequent monitoring, an innovative data collection strategy involving a partnership between fishermen and scientists, was developed in 2009 and 2010 called “pilot sentinel surveys”. This paper details the partnership, the information such a...

A Penny Saved: Prices and the Timing of Paycheck Receipt
Provedor de dados: 31
Autores: Beatty,   Timothy K.M.
This paper explores a puzzling empirical regularity: households pay less for foods as the time since receipt of their last paycheck increases. I leverage randomization with regard to paycheck timing to causally identify the effect of time since paycheck receipt on prices. Estimates of the decline in prices range between 5% and 6% percent, over the course of a month. I investigate several potential explanations for this behavior, including credit constraints and stockpiling. I find evidence that the effect is driven by low-income households and exacerbated by stockpiling behavior.

Provedor de dados: 69
Autores: Yulita,Kusumadewi Sri; Kouno,Takafumi; Ezaki,Bunichi.
Here we introduce a new approach for the screening of DNA binding proteins, using a phage library based on a phage display technique. In principal, a complementary DNA (cDNA) library based on the recombinant bacteriophage T7 expressing target proteins on its capsid (phage display) is constructed. These phage particles are hybridized with a biotinylated target DNA fragment which is immobilized on the surface of streptavidin paramagnetic particle (SA-PMP). The phage particles are released from the target DNA fragment by a nuclease treatment and the recovered phages are used to the next round of hybridization. These processes are repeated three times to amplify the target phages in the population. This simple method is faster, and more systemic than other...

A physiological and biochemical approach to selecting the ideal diet for Ostrea edulis (L.) broodstock conditioning (part A)
Provedor de dados: 5
Autores: Gonzalez-araya, Ricardo; Queau, Isabelle; Quere, Claudie; Moal, Jeanne; Robert, Rene.
To select the best microalgae for Ostrea edulis conditioning, four single species diets were fed to batches of broodstock, which were then compared using physiological and biochemical approaches. Ingestion and absorption were first studied, showing that Chaetoceros gracilis and Skeletonema marinoï were efficiently ingested (4.9–5.3 mg g−1 h−1) and absorbed (1.9–2.5 mg g−1 h−1) while Tetraselmis suecica led to the lowest physiological responses (0.36 and 0.12 mg g−1 h−1 respectively). When O. edulis were fed any microalgae except T-ISO with only 79 mg g−1, gonads accumulated carbohydrates from 116 to 141 mg g−1 and the extent of accumulation depended on the species supplied in the order T. suecica&lt;C. gracilis&lt;S. marinoï. When oysters were fed either...

A Policy Tool for Evaluating Investments in Public Boat Ramps in Florida: A Random Utility Model Approach
Provedor de dados: 31
Autores: Thomas,   Michael H.; Lupi,   Frank; Harding,   David B.
Across the country many people engage in recreational boating. In 2008 there were over 12 million registered recreational boats in the United States, and nearly 8% of these were in Florida (US Coast Guard, 2008).  Launching boats from publically available ramps is one of the primary methods of marine access.  Within Florida, nearly 25% of all boating related trips in 2007 involved launching a trailered boat from a publically available ramp (Florida Fish and Wildlife Conservation [FWC], 2009).  With hundreds of thousands of boating trips from dozens of publically accessible ramps, Lee County planners need analytical tools to understand demand and consumer surplus to assist them in evaluating new and enhanced launch facilities.

Provedor de dados: 21
Autores: Rover, Oscar José; Munarini, Paulo Roberto.
Este artigo analisa a contribuição do Programa Nacional de Habitação Rural (PNHR) para o desenvolvimento de territórios predominantemente rurais. A partir do estudo de sua implementação na região Oeste Catarinense, ponder sobre os avanços e as restrições desta política social. Para as análises realizadas procedeu-se a uma revisão de literatura, à busca de documentação sobre a política e sua implementação na região estudada, bem como a entrevistas com lideranças e agricultores demandantes e beneficiados por uma casa nova ou reforma. Verificou-se que o PNHR cria uma oportunidade para as famílias rurais descapitalizadas construírem ou reformarem sua casa, apesar de ser ainda restrita a sua abrangência para o conjunto dessas famílias. A reformulação do...

A Portfolio Approach for the New Zealand Multi-Species Fisheries Management
Provedor de dados: 31
Autores: Yang,   Ming Ming; Sharp,   Basil M.H.; Sbai,   Erwann.
Marine species are reproducible resource. Maintaining the stock level of marine species and the sustainability of fisheries development become critical issues in current scientific research areas due to the explosion of human population and exacerbation of natural environment. The traditional method that protects the marine species is the single species approach which set maximum sustainable yield (MSY) to prevent over-harvest. However, with the development of technology and comprehension of marine science, the single species approach has been found obsolete and incapable of dealing with problems of severe depletion of fish stocks and escalation of fisheries confliction. Studies show that when regulations are species specific and species are part of a...

Autores: Lericolais, Gilles; Guichard, F.; Morigi, C.; Minereau, Amelie; Popescu, Irina; Radan, S.
The north-western Black Sea shelf is the widest continental shelf of the Black Sea, where the Danube delta/prodelta system includes important records on the Black Sea water level fluctuations. This study integrates newly acquired high-resolution single channel seismic reflection profiles and Calypso piston cores recovered along a transect extending from the Danube delta deep into its deep sea fan. The correlated results provide information on the Late Quaternary architecture of the Danube Black Sea shelf and on the role of global glacio-eustatic fluctuations on the building of the Danube delta/prodelta. The sedimentary sequences in the Black Sea are strongly affected by water level changes. For the whole duration of Late Glacial-Holocene period, the level...

A Postcard from Oxford: Rudolf Steiner at Manchester College
Provedor de dados: 21
Autores: Paull, John.
At the height of his powers, Rudolf Steiner presented a two-week conference at Oxford. The ‘Oxford Holiday Conference’ was titled ‘Spiritual Values in Education &amp; Social Life’ (Mackenzie, 1922b), and it was this 1922 conference that laid the foundations for establishing Waldorf education in Britain and from there the rest of the Anglo world. The original Waldorf School had been established in 1919 by Rudolf Steiner at the invitation of a German industrialist, Emil Molt, in Stuttgart, Germany. Steiner states that in the Waldorf School he sought "to apply the educational principles arising out of Anthroposophy”. The Stuttgart school began with 150 students and this had grown to 700 by the time of the Oxford Conference. The Oxford Conference ran from...

A precariedade do transporte rodoviário brasileiro para o escoamento da produção de soja do Centro-Oeste: situação e perspectivas
Provedor de dados: 123
Autores: Correa,Vivian Helena Capacle; Ramos,Pedro.
O Centro-Oeste do Brasil se destaca como um pólo produtor de soja. Pela crise fiscal do Estado, a partir dos anos 80, a malha rodoviária brasileira perde investimentos públicos para sua ampliação, conservação e restauração, refletindo na competitividade internacional da oleaginosa dos cerrados. Isso porque o principal modal utilizado para o escoamento da produção do grão aos portos das regiões Sul e Sudeste é o rodoviário, com destaque para as rodovias BR 163 e 364. Por conta da inadequação desse modal às características do produto e às longas distâncias percorridas, aliada ao estado precário de conservação da malha rodoviária do País, 25% da receita de vendas da produção de soja está comprometida com os custos internos de transportes. Neste trabalho,...

A precíziós gazdálkodás terjedésének vizsgálata
Provedor de dados: 31
Autores: Kalmar,   Sandor.
A precíziós gazdálkodás – 90-es évek közepétől kezdődő – alkalmazását követően napjainkban is megválaszolásra vár a beruházás megtérülési idejének és a területnagyságnak az összefüggése. Megállapítható, hogy a beruházás az eszközök gyors avulását figyelembe véve, 3 éves megtérülés esetén, 3 millió Ft (áfával együtt) értékű eszközberuházás, 21 140 Ft/ha inputfelhasználás és 5%-os megtakarítási szint mellett 946 ha-on térülhet meg az inputanyag-megtakarításból. Természetesen több végeredmény is lehetséges a változók függvényében.  --------------------------------------  Ever since precision farming was introduced in the mid-nineties, correlations between payback period and area size have been unexplored. It was found that – taking into account the quick...

A precíziós növénytermelés externális hatásai az Agárdi Farm Kft. esetében
Provedor de dados: 31
Autores: Sinka,   Anett.
A hagyományos mezőgazdasági termelés negatív hatásainak kiküszöbölése ér¬dekében az Európai Unió országaiban az utóbbi évtizedben egyre fontosabbá vált a multifunkcionális mezőgazdaság. Ahhoz, hogy a vidékfejlesztés, a környezetgazdálkodás az agrárgazdaság integrált részévé váljék, a gazdasági gyakorlatnak szá¬mos területen szükséges változtatni: merőben új módszerek alkalmazása, a koráb¬ban használt vagy meglévő technológiák megújítása, mások által már kipróbált eljá¬rások adaptálása, mind-mind egy-egy lehetőséget kínál a jól működő, többfunkciós mezőgazdasághoz. Mindezen okok mérlegelése után döntött úgy az Agárdi Farm Kft., hogy átáll a ha¬gyományos gazdálkodásról a precíziós növénytermelésre. A precíziós növényterme¬lési technológia nem más, mint a...

A Primer On Collective Entrepreneurship: A Preliminary Taxonomy
Provedor de dados: 31
Autores: Burress,   Molly J.; Cook,   Michael L.
We document an increasing prevalence of the term ―collective entrepreneurship‖ in scholarly research. By examining the context in which the term is utilized, we present a framework through which to understand motivations for research in collective entrepreneurship and the variety of entrepreneurial endeavors described as collective entrepreneurship. We identify five primary motivations for research: advancement of theory, intra-organizational efficiency, inter-organizational gains, economic growth and development, and socio-political change. We find preliminary evidence collective entrepreneurs may be able to generate rents inaccessible to the sole entrepreneur. In addition, we propose mechanisms which foster entrepreneurship may differ for sole and...

A probabilistic model of plasmid replication regulation by a combination of handcuffing, iteron number and dimerization of RepA protein.
Provedor de dados: 17
Autores: Milind Watve; Gauri Tendulkar; Ketaki Ghate.
Plasmids are small circular DNA molecules in bacteria which replicate sharing the replication machinery with the bacterial chromosome. Since plasmids are much smaller than the chromosome, unless their replication is tightly regulated, their copy numbers can escalate quickly. A number of mechanisms of plasmid replication regulation are known in P1 plasmid of E. coli. Mechanisms such as autorepression of the replication initiator protein (RepA) and its dimerization are unable to explain copy number regulation by themselves. The number of RepA binding sites (iterons) is inversely related to copy numbers. Handcuffing of plasmids by RepA dimer is believed to be the main mechanism of arresting replication. We show here with a probabilistic model that for the...

A prototyping method for the re-design of intensive perennial systems: the case of vineyards in France
Provedor de dados: 21
Autores: Metral, Raphaël; Rapidel, Bruno; Delière, Laurent; Petitgenet, Morgane; Lafond, David; Chevrier, Christel; Bernard, François-Michel; Serrano, Eric; Thiollet-Scholtus, Marie; Wéry, J.
The results of our re-design and experimentation of grapevine agrosystem, as well as on the other crops (Lançon et al., 2007 and Wery &amp; Langeveld, 2010) show promising perspectives of the prototyping method to achieve high goals for performance and innovation. The complexity of the grapevine agrosystem (ie the number of technical interventions and their potential interactions) requires a strong systemic approach at the interface between the technical and biophysical dimensions of cropping systems (Rapidel et al., 2009). The approach must implement agro-ecological processes to greatly limit inputs. It also required a high innovation and significant changes in the grapevine agrosystem genetics, structure and management. Our results point out the need to...

A Pseudo-Sequential Choice Model for Valuing Multi-Attribute Environmental Policies or Programs in Contingent Valuation Applications
Provedor de dados: 31
Autores: Volinskiy,   Dmitriy; Bergstrom,   John C.; Cornwell,   Christopher M.; Holmes,   Thomas P.
The assumption of independence of irrelevant alternatives in a sequential contingent valuation format should be questioned. Statistically, most valuation studies treat nonindependence as a consequence of unobserved individual effects. Another approach is to consider an inferential process in which any particular choice is part of a general choosing strategy of a survey respondent. A stochastic model is suggested, consistent with the reflexivity, transitivity, and continuity axioms of utility analysis. An application of this theoretical model to the valuation of watershed ecosystem restoration demonstrates that an empirical model recognizing reflexivity and transitivity, and also allowing for continuity, shows the highest in-sample predictive ability.

A putative mutant of a self-compatible yellow passion fruit with the corona color as a phenotypic marker
Provedor de dados: 53
Autores: Souza,Margarete Magalhães; Viana,Alexandre Pio; Pereira,Telma Nair Santana.
Yellow passion fruit (Passiflora edulis f. flavicarpa) is a self-incompatible crop with purple corona flowers (PCF). Plants exhibiting white corona flowers (WCF) were observed in an experimental field located in Campos dos Goytacazes - RJ, Brazil. This study was performed in order to test the fertility of these genotypes through studies of in vivo pollination, meiotic behavior and pollen viability. Using in vivo pollination, the mean fruit set percentage, obtained from self-pollinations at the moment that flowers open, was 70.83% in WCF and 0% in PCF. In terms of cytological analysis, for both kinds of plants, WCF and PCF, the meiotic behavior was considered regular, considering the high meiotic index estimated for both of them, 96.3% and 97.7%, and pollen...

A Quantitative Assessment of the Morphological Characteristics of BeWo Cells as an in vitro Model of Human Trophoblast Cells
Provedor de dados: 77
Autores: Abaidoo,C.S; Warren,M. A; Andrews,P. W; Boateng,K. A.
In order to study the detailed morphology of trophoblast cells during human implantation, BeWo cells were cultured as spheroids in suspension culture. These cultures were then processed for light and electron microscopical examination. The present study showed that the BeWo spheroids consist of two cell types which are cytotrophoblast-like and syncytiotrophoblast-like. The cells with larger nuclear diameter made up only about 1% of the cell population and appear to be those of syncytiotrophoblast. Therefore the predominant cell type of the BeWo spheroids appeared to be relatively undifferentiated and cytotrophoblast-like. About 10% of the BeWo cells in the present study were mitotic, indicating a highly proliferative population. Total cell number increased...

A quantitative study of the influence of coprocessing of binders on the mechanical properties of paracetamol tablets
Provedor de dados: 60
Autores: Ogunjimi,Abayomi Tolulope; Alebiowu,Gbenga.
A 2³ factorial experimental design has been used to quantitatively study individual and interaction effects of the nature of binder (N), concentration of binder (C) and the applied pressure (P) on two mechanical properties, namely, tensile strength (TS) and brittle fracture index (BFI), of paracetamol tablets. The factorial design was also used to study the quantitative effects of coprocessing of binders on the mechanical properties. The results obtained from this study suggest that the nature (i.e. plastic/elastic) and ratio of binders coprocessed together alter the influence of C and P on TS and BFI.

A Race to Develop: A Competing Risk Examination of the Pattern and Timing of Land Development in an Exurban County
Provedor de dados: 31
Autores: Wrenn,   Douglas H.
Rural-urban fringe counties (i.e. counties adjacent to other counties with large and growing urban centers) often experience intense development pressure as a result of urban growth and expansion. While growth-initiated development can take many forms, the majority of the development that occurs in these exurban counties is in the form of single-family residential dwellings. Moreover, it is in the form of subdivision developments that range in size from very small two and three lot minor subdivisions to massive multi-phase major subdivisions with hundreds of lots and numerous amenities. In this paper, we focus on the land development patterns in Carroll County, MD, an urban-fringe county in the Baltimore-Washington D.C. metro region. The purpose of this...

Provedor de dados: 117
Autores: Sangüesa,Claudia; Arumí,José; Pizarro,Roberto; Link,Oscar.
A rainfall simulator is an important tool for the study of runoff generation and soil loss because it can be used either under laboratory conditions, or in disturbed or natural soil. The objective of this study was to describe the design and operation of a rainfall simulator to evaluate soil loss in situ. The rainfall simulator has four full-cone spray nozzles with a Unijet system mounted in a straight line pipe configuration, and easily transported and assembled. Simulated rainfall uniformity was evaluated in the laboratory, whereas the applicability of the simulator in natural soil erosion plot conditions in an experimental field with different slopes was tested by quantifying runoff and evaluating soil erosion. Twenty simulations were carried out in the...

A randomized controlled trial to compare the use of homeopathy and internal Teat Sealers for the prevention of mastitis in organically farmed dairy cows during the dry period and 100 days post-calving.
Provedor de dados: 21
Autores: Klocke, P.; Ivemeyer, S.; Butler, G.; Maeschli, A.; Heil, F.
Introduction: Routine use of antibiotics to prevent mastitis in dairy cows is prohibited by organic farming regulations. Internal Teat Sealers have been proposed as an alternative. We compared two drying-off (DO) supporting measures (Internal Teat Sealer and Homeopathy) to an untreated control group to assess their protective effects against clinical mastitis and intra-mammary infections during dry period of dairy cows.  Methods: A field trial with 102 dairy cows from 13 Swiss organic dairy farms was conducted. Cows were randomly assigned to one of three groups within a herd. In the Internal Teat Sealer group (ITS; 36 cows) cows were treated with the commercial ORBESEAL (Pfizer) in all four quarters immediately after the last milking. In the Homeopathy...

A Rate Distortion approach to protein symmetry

Autores: Rodrick Wallace.
A spontaneous symmetry breaking argument is applied to the problem of protein folding, via a Rate Distortion analysis of the relation between genome coding and the final condensation of the protein molten globule. In the &amp;#x27;energy&amp;#x27; picture, the average distortion between codon message and protein structure, under constraints driven by evolutionary selection, serves as a temperature analog, so that low values limit the possible distribution of protein forms, producing the canonical folding funnel. A dual &amp;#x27;developmental&amp;#x27; perspective sees the rate distortion function itself as the temperature analog, and permits incorporation of chaperons or toxic exposures as catalysts, driving the system to different possible outcomes or...

A Rate Distortion approach to protein symmetry

Autores: Rodrick Wallace.
A spontaneous symmetry breaking argument is applied to the problem of protein form, via a Rate Distortion analysis of the relation between genome coding and the final condensation of the protein &amp;#x27;molten globule&amp;#x27;. The Rate Distortion Function, under coding constraints, serves as a temperature analog, so that low values act to drive proteins to simple symmetries. The Rate Distortion Function itself is significantly constrained by the availability of metabolic free energy. This work extends Tlusty&amp;#x27;s (2007) elegant exploration of the evolution of the genetic code, suggesting that rate distortion considerations may play a critical role across a broad spectrum of molecular expressions of evolutionary process.

A Real Options Framework for Analyzing Program Participation as Human Capital Investments: The Case of the Average Crop Revenue Election (ACRE) Program
Provedor de dados: 31
Autores: Mitchell,   Paul D.; Rejesus,   Roderick M.; Coble,   Keith H.; Knight,   Thomas O.
We develop a real options framework to model producer participation in a subsidy program as a human capital investment to learn how the stochastic subsidy affects returns and how to adapt production activities to new program incentives, formally linking the framework to a multinomial logit specification for empirical applications.  Analysis of farmer intentions for participation in the ACRE program created by the 2008 Farm Bill finds that reluctance to participate was driven largely by risk aversion and perceptions about income risk from yield and price variability, consistent with the theory that uncertainty creates an option value discouraging human capital investments.

A Reassessment of Agriculture’s Role on the Rural Poverty Reduction Process in Bangladesh
Provedor de dados: 31
Autores: Ahmed,   Sharmina.
In 2005, roughly 45% of the total populations of Bangladesh living below the poverty line and of them 53% are rural poor people. Therefore, a significant gain in rural poverty reduction will be crucial for Bangladesh to reach the national poverty reduction target. As 63% of the total employed people engage in some kind of agricultural activities, without pro-poor agricultural growth it is impossible for a country like Bangladesh to reduce poverty. This article attempts to analyse the impact of agricultural growth on rural poverty reduction by using time series analysis in Bangladesh during 1973 to 2003. The study shows that rural poverty reduction is possible by increased agricultural production, for which again efficient spending of government budget and...

A recent decline in North Atlantic subtropical mode water formation

Autores: Stevens, Samuel W.; Johnson, Rodney J.; Maze, Guillaume; Bates, Nicholas R.
As a manifestation of mixing dynamics in the upper ocean, interannual and decadal variability of subtropical mode water (STMW) properties in the North Atlantic Ocean provides a valuable insight into ocean–atmosphere interaction in a changing climate. Here, we use hydrographic data from the Bermuda Atlantic Time-Series Study and Hydrostation S sites near Bermuda, as well as various ocean reanalysis products, to evaluate the modern variability of STMW properties. Our study finds an 86–93% loss of STMW thickness at these sites between 2010 and 2018 and a comparable loss throughout the western subtropical gyre, culminating in the weakest STMW pentad on record. We correlate this decline with a reduction in the annual outcropping volume and northward excursions...

A Re-examination of Factors Affecting United States Softwood Lumber Imports from Canada
Provedor de dados: 31
Autores: Baek,   Jungho.
This paper examines the effects of the lumber price, the housing starts, and the bilateral exchange rate on U.S. softwood lumber imports from Canada in a cointegration framework. To that end, the Phillips-Hansen fully-modified cointegration (FM-OLS) procedure is applied to monthly data for the period from January 1994 through June 2009. Results show that there exists the long-run equilibrium relationship between the U.S. lumber imports from Canada and the selected macroeconomic and market variables. We also find that the U.S. lumber price and housing starts are more important than the bilateral exchange rate in influencing U.S.-Canada softwood lumber trade.

A Reexamination of the U.S. Export Demand for Soybeans and Soybean Products
Provedor de dados: 31
Autores: Uri,   Noel D.; Hyberg,   Bengt.
This paper addresses the question of whether the export demand for soybeans and soybean products changed structurally over the 1950 to 1992 period as the U.S. agricultural sector became more integrated with the rest of the world economy. The results suggest that export demands were stable for soybeans, soybean meal and soybean oil over the sample period. Moreover, it is possible to infer conclusively that the long-run soybean and soybean product export price elasticities were in the elastic range. The implications include that for each one percent reduction in the price of soybeans, soybean meal and/or soybean oil brought about through a government program, exports increased by more than one percent, leading to a reduction in the variability of soybean and...

CHINA is currently the world largest emitter of energy-related carbon dioxide (CO2). Understanding the driving forces governing CO2 emission levels and their evolutions in China can provide useful information for policy makers who aim to reduce green house gas emissions. Because of policy and historical reasons, considerable regional growth and income disparities exist in China. The regional disparities may influence energy use and CO2 emissions. Therefore, this study is to investigate the driving forces governing CO2 emission levels and their evolutions at regional level in China.

A Retail Sales / Sales Tax Paradox
Provedor de dados: 31
Autores: Lansford,   Notie H., Jr.; Brorsen,   B. Wade; Woods,   Michael D.
Small communities experiencing slow to negative growth sometimes increase their local sales tax rate in order to maintain or expand public services.  A cross-sectional, time series model is used to investigate possible unintended consequences.  Negative elasticities are found for tax rates above the norm, resulting in reduced retail trade.

A Return of the Threshing Ring? A Case Study of Machinery and Labor-Sharing in Midwestern Farms
Provedor de dados: 31
Autores: Artz,   Georgeanne M.; Colson,   Gregory; Ginder,   Roger G.
Machinery-sharing provides an alternative for smaller producers to obtain the efficiencies of large farming operations and remain competitive in an increasingly concentrated agricultural industry. This research uses a multiple case study design to examine the motivations for sharing equipment and labor among farms and to better understand how group members handle the transaction costs of sharing. Our case evidence finds that in addition to cost savings, access to reliable labor is an important motivation for participating in a sharing arrangement. Trust and frequent communication among group members helps to minimize the transaction costs incurred from sharing.

A Review of Agricultural Policy Evolution, Agricultural Data Sources, and Food Supply and Demand Studies in Egypt
Provedor de dados: 31
Autores: Soliman,   Ibrahim; Fabiosa,   Jacinto F.; Bassiony,   Halah.
Over the years the control of the Government of Egypt on the agricultural sector has increasingly weakened with the progressive elimination of the input subsidy, area control, price control, procurement control, and the constraints in private sector participation in processing and trade. The only remaining major government involvement is the food subsidy in some wheat products, the “baladi” bread subsidy in particular.  Policy analysis studies in Egypt have been made possible because the Government of Egypt collects and publishes significant amounts of agricultural data on a regular basis. Two of the most widely used data sets are the Household Budget Survey conducted and published by the Central Agency for Public Mobilization and Statistics, and the Food...

A Review of Design Principles for Community-based Natural Resource Management
Provedor de dados: 7
Autores: Cox, Michael; Indiana University; miecox@indiana.edu; Arnold, Gwen; Indiana University; gbarnold@indiana.edu.
In 1990, Elinor Ostrom proposed eight design principles, positing them to characterize robust institutions for managing common-pool resources such as forests or fisheries. Since then, many studies have explicitly or implicitly evaluated these design principles. We analyzed 91 such studies to evaluate the principles empirically and to consider what theoretical issues have arisen since their introduction. We found that the principles are well supported empirically and that several important theoretical issues warrant discussion. We provide a reformulation of the design principles, drawing from commonalities found in the studies.

A Review of FDA Imports Refusals - US Seafood Trade 2000-2010
Provedor de dados: 31
Autores: Anders,   Sven M.; Westra,   Sabrina.
The United States is the third largest consumer of seafood products in the world. The percentage of imported seafood consumed in the U.S. has steadily increased from 66% in 1999 to over 84% in 2009 (NOAA, 2010). Food safety, especially of imported foods and products from developing countries, has raised increasing concerns among American consumers and policy makers. Accordingly, the Food and Drug Administration’s (FDA) (Ababouch et al. 2000) border inspection system is considered critical for ensuring the safety of domestic seafood consumers. However, the potential non-tariff barrier to trade posed by FDA regulations, especially for many developing country exporters have been frequently cited in the literature.  This paper investigates trends and patterns...

Autores: Kaye-Blake,   William; Li,   Frank Y.; Martin,   A. McLeish; McDermott,   Alan; Neil,   Hayley; Rains,   Scott.
Multi-Agent Simulation (MAS) models are intended to capture emergent properties of complex systems that are not amenable to equilibrium analysis. They are beginning to see some use for analysing agricultural systems. The paper reports on work in progress to create a MAS for specific sectors in New Zealand agriculture. One part of the paper focuses on options for modelling land and other resources such as water, labour and capital in this model, as well as markets for exchanging resources and commodities. A second part considers options for modelling agent heterogeneity, especially risk preferences of farmers, and the impacts on decision-making. The final section outlines the MAS that the authors will be constructing over the next few years and the types of...

The main objective of the LAgrangian Transport EXperiment (LATEX) project was to study the influence of coastal mesoscale and submesoscale physical processes on circulation dynamics, cross-shelf exchanges, and biogeochemistry in the western continental shelf of the Gulf of Lion, Northwestern Mediterranean Sea. LATEX was a five-year multidisciplinary project based on the combined analysis of numerical model simulations and multi-platform field experiments. The model component included a ten year realistic 3D numerical simulation, with a 1 km hor-izontal resolution over the gulf, nested in a coarser 3 km resolution model. The in situ component involved four cruises, including a large-scale multidisciplinary campaign with two research vessels in 2010. This...

Nos últimos meses está em efervescente discussão uma proposta para que um novo código florestal (Projeto de Lei nº 1876/99) substitua o vigente instaurado por meio da Lei Federal nº 4771/65 e modificado recentemente por Medidas Provisórias. Este novo código proposto, todavia, propõe alterações legais que devem afetar negativamente as populações naturais de anfíbios do Brasil. O declínio de anfíbios deve gerar impactos negativos tanto para a população (humana) nacional, como para a comunidade internacional. Entre os possíveis efeitos dessa lei, em consequência da perda de diversidade de anfíbios, podemos citar o aumento nos custos de produção agrícola, perda de matéria prima para produção de remédios, descontrole ecológico, eutrofização de corpos d'água,...

A Ricardian analysis of the impact of climate change on African cropland
Provedor de dados: 31
Autores: Kurukulasuriya,   Pradeep; Mendelsohn,   Robert.
This study examines the impact of climate change on cropland in Africa, using a Ricardian cross-sectional approach. Relying on farm data from an 11-country survey of over 9500 farmers, annual net revenue is regressed on climate and other variables. The study confirms that current climate affects the net revenues of farms across Africa. Applying these results to possible future climates reveals that dryland farms are especially climate sensitive. Even as early as 2020, climate change could have strong negative impacts on currently dry and hot locations. By 2100, dryland crop net revenues could rise by 51% if future warming is mild and wet but fall by 43% if future climates are hot and dry. The crop net revenues of currently irrigated farms are likely to be...

A Rising Tide of Anti-Animal Consumerism? Issues and Opportunities
Provedor de dados: 31
Autores: Rae,   Allan N.
The livestock revolution that has occurred over the last few decades has seen a phenomenal increase in demand for livestock products in much of the developing world. This has largely been matched with growth in supplies, driven by government policies, and increased animal numbers and productivity. But this growth has been accompanied by a number of side-effects which in many cases impose negative externalities on society and suggest that current trends in animal product consumption are unsustainable. As a result there is emerging an anti-animal sentiment among some consumer groups. These people are concerned about livestock issues such as human health effects, biodiversity losses, deforestation, emissions to the air and water, diversion of grains from...

A role for icebergs in the 8.2 ka climate event
Provedor de dados: 5
Autores: Wiersma, Ane P.; Jongma, Jochem I.
We investigate the potential role of icebergs in the 8.2 ka climate event, using a coupled climate model equipped with an iceberg component. First, we evaluate the effect of a large iceberg discharge originating from the decaying Laurentide ice sheet on ocean circulation, compared to a release of an identical volume of freshwater alone. Our results show that, on top of the freshwater effect, a large iceberg discharge facilitates sea-ice growth as a result of lower sea-surface temperatures induced by latent heat of melting. This causes an 8% increased sea-ice cover, 5% stronger reduction in North Atlantic Deep Water production and 1A degrees C lower temperature in Greenland. Second, we use the model to investigate the effect of a hypothetical two-stage lake...

A Rule of Thumb for Controlling Invasive Weeds: An Application to Hawkweed in Australia
Provedor de dados: 31
Autores: Kompas,   Tom; Chu,   Long.
We use a bang-bang optimal control model to derive a rule of thumb for an optimal management of invasive weeds, in terms of the marginal benefits and costs of various control actions. Instead of determining the size of infestation under an optimal surveillance measure, the rule specifies the types of land where an invasive weed should be first prevented from establishment, and under what conditions control should be initiated. The types of land are modeled via the heterogeneous vulnerability of land to the weed and likely infestation. This easy-to-use rule is applied to determine how hawkweed should be controlled in Australia, across three potential control strategies: containment, eradication and no action. We investigate this rule-of-thumb in both...

A schistosome [beta] subunit remodels inactivation of a calcium channel _via_ an N-terminal polyacidic motif
Provedor de dados: 17
Autores: Vicenta Salvador-Recatala; Robert M. Greenberg.
The beta subunit of high voltage-activated Ca (Cav) channels targets the pore forming [alpha]~1~ subunit to the plasma membrane and defines the biophysical phenotype of the Cav channel complex. Cav channel inactivation following activation and opening is tightly regulated and is an essential property that not only prevents excessive entry of Ca^2+^ into the cell but may also have functions in signal transduction. The [beta] subunit modulates Ca^2+^-dependent and voltage-dependent components of Cav channel inactivation via its interaction with the I-II linker of the [alpha]~1~ subunit. Here, using Cav2.3 and whole-cell patch-clamp, we show that a [beta] subunit from the human parasite _Schistosoma mansoni_ ([beta]~Sm~) accelerates inactivation via a unique,...

A Scientific Review of the Impact of UK Ruminant Livestock on Greenhouse Gas Emissions
Provedor de dados: 31
Autores: Hopkins,   Alan; Lobley,   Matt.
Climate change is a subject of global environmental concern. The UK has seen a progressive strengthening of political resolve to address the problems associated with emissions of greenhouse gases (GHGs), principally carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). Although agriculture globally, and ruminant livestock production in particular, is a net contributor to GHG emissions, generalizations about impacts on climate change often fail to distinguish between different systems of production, advances in technology, and the role of extensive grazing lands in contributing to ecological services and food production in situations where other forms of farming are impractical. Against this background, the overall aim of this review was therefore to...

Provedor de dados: 31
Autores: de los Campos,   Gustavos; Foltz,   Jeremy D.; Chavas,   Jean-Paul; Gianola,   Daniel.
This article proposes a semi-parametric stochastic frontier model (SPSF) in which components of the technology and of technical efficiency are represented using semi-parametric methods and estimated in a Bayesian framework. The approach is illustrated in an application to US farm data. The analysis shows important scale economies for small and medium herds and constant return to scale for larger herds. With the exception of labor, estimates of marginal products were close to the value expected under profit maximization. Finally, the results suggest important opportunities to increase productivity through reductions in technical inefficiencies.

Sample preparation for Two-dimensional gel electrophoresis (2DE) is tedious and not sufficient to provide a comparative profile of secreted proteins for various strains of M. tuberculosis. High lipid content in mycobacteria limits the use of common methods as it can hinder the 2DE run. This study highlights the significance of SDS-TCA procedure over common used methods for the preparation of sample from culture filtrate as well as other proteinaceous fluids.

A simple method to assess freezing of gait in Parkinson's disease patients
Provedor de dados: 56
Autores: Popovic,M.B.; Djuric-Jovicic,M.; Radovanovic,S.; Petrovic,I.; Kostic,V.
Freezing of gait (FOG) can be assessed by clinical and instrumental methods. Clinical examination has the advantage of being available to most clinicians; however, it requires experience and may not reveal FOG even for cases confirmed by the medical history. Instrumental methods have an advantage in that they may be used for ambulatory monitoring. The aim of the present study was to describe and evaluate a new instrumental method based on a force sensitive resistor and Pearson's correlation coefficient (Pcc) for the assessment of FOG. Nine patients with Parkinson's disease in the "on" state walked through a corridor, passed through a doorway and made a U-turn. We analyzed 24 FOG episodes by computing the Pcc between one "regular/normal" step and the rest...

A Simple Theory of Predation
Provedor de dados: 31
Autores: Fumagalli,   Chiara; Motta,   Massimo.
We propose a simple theory of predatory pricing, based on scale economies and sequential buyers (or markets). The entrant (or prey) needs to reach a critical scale to be successful. The incumbent (or predator) is ready to make losses on earlier buyers so as to deprive the prey of the scale it needs, thus making monopoly profits on later buyers. Several extensions are considered, including markets where scale economies exist because of demand externalities or two-sided market effects, and where markets are characterised by common costs. Conditions under which predation may take place in actual cases are also discussed.

A simulation study on different STDP models concerning localized gamma oscillations
Provedor de dados: 17
Autores: Florian Hauser; Andreas Knoblauch; G&amp;#xfc;nther Palm.
Gamma oscillations are a prominent feature in experimental as well as theoretical descriptions of brain activity. One of the network models which has the capability to generate such oscillations is what we call a local cell assembly (CA), i.e. a group of neighboring neurons which are strongly interconnected in an excitatory manner. Postulated by experimenters and extensively used in theoretical studies, these local networks seem to be a good candidate for investigating the impact of biological constraints given by models of spike-timing-dependent plasticity (STDP) on local gamma oscillating structures in the mammalian brain. Therefore we fi&amp;#xc;tted a two-compartment neuron model with AMPA- and NMDA-receptor mediated synaptic currents to desired...

Primary antibody deficiencies (PADs) are a heterogeneous group of disorders, characterized by hypogammaglobulinemia and increased susceptibility to bacterial infections, leading to hospitalizations. This study was performed to determine the main infectious causes of hospital admissions in selective Iranian patients with PADs. Forty patients with PADs, who were admitted to the Infectious Ward of Children's Medical Center Hospital during a 14-year period, were reviewed in this study. There were 115 documented episodes of hospital admission during a 14-year period. The average length of hospital stay was 33.30 ± 25.72 days. Pneumonia was the most prominent infection leading to hospitalization among these patients (n = 48), followed by gastroenteritis (n =...

A SLUGGISH DEMAND COULD BE AS POTENT AS TECHNOLOGICAL PROGRESS IN CREATING SURPLUS IN STAPLE PRODUCTION: THE CASE OF BANGLADESH
Provedor de dados: 31
Autores: Ahmed,   Raisuddin.
During the decade from 1982/83 through 1992/93, Bangladesh was able to increase production of rice, its staple food, at a rate modestly higher than the growth in population. However, the growth in per capita supply remained stagnant, because of the substitution of imports with domestic production. On the other hand, per capita income grew about 2 percent per annum. Nevertheless, the real price of rice declined about 2.7 percent annually. This decline in the rice price, on the face of a stagnant supply and increasing incomes, aroused suspicion whether income distribution has twisted against the poor who have a higher marginal propensity to consume rice compared to the rich. Three factors are identified that contributed to the decline in the rice price while...

A small nation’s comparative advantage: The case of Latvia
Provedor de dados: 31
Autores: Fedotovs,   Aleksandrs.
Problem of comparative advantage in international trade is important in theoretical and practical aspect. Theoretical models in this area are periodically re-examined in search for empirical evidence. The aim of the paper is to verify the two fundamental theories in the case of a small European country - Latvia - and disclose problems in the country’s trade specialization. In Latvia’s trade with “old” EU countries, the Ricardian model and the Heckscher-Ohlin theorem can be corroborated. After 2000, however, share of EU-15 countries in Latvia’s exports steadily declines. Instead, share of regional (Baltic) market increases, while the potential of CIS markets remains underexploited. Problem of identifying new areas of comparative advantage has become...

Autores: Doglioli, Andrea; Nencioli, Francesco; Petrenko, Anne; Rougier, Gilles; Fuda, Jean-luc; Grima, Nicolas.
The Lagrangian Transport Experiment (LATEX) was developed to study the influence of coupled physical and biogeochemical dynamics at the meso- and submesoscales on the transfers of matter and heat between the coastal zone and the open ocean. One of the goals of the Latex10 field experiment, conducted during September 2010 in the Gulf of Lion (northwest Mediterranean), was to mark a dynamical mesoscale feature by releasing a passive tracer [sulfur hexafluoride (SF6)] together with an array of Lagrangian buoys. The goal was to release the tracer in an initial patch as homogeneous as possible in the horizontal, and to study its turbulent mixing and dispersion while minimizing the contribution due to advection. For that, it was necessary to continuously adjust...

Az elemzés szerint a Somogy megyei vadásztársaságok nyereségesek voltak. Az összköltség szignifikánsan (p&lt;0,05) befolyásolta a bevételek nagyságát. A vizsgált időtartam alatt a legnagyobb bevételi forrás (értékben, arányban) a kül-földi bérvadásztatásból, a legjelentősebb kiadás a vadgazdálkodási költségből származott. A 2004. évben a nagymértékű kiadásnövekedést a Somogy megyei vadásztársaságok kompenzálták, de az eltérő adottságok és lehetőségek miatt, a felmerült problémát a társaságok különböző módon oldották meg (pl. tagdíj nö-velésével, a vaddisznóhajtás értékesítésével, tárgyi eszközök értékesítésével, a vadgazdálkodási költség csökkentése segítségével).

Autores: Nzaku,   Kilungu; Houston,   Jack E.; Fonsah,   Esendugue Greg.
A source-differentiated Almost Ideal Demand System model is used to analyze U.S. demand for the major tropical fresh fruit imports from different countries of origin. The tropical fresh fruits chosen for analysis include fresh bananas, fresh pineapples, papayas, and mangoes/guavas. To address endogeneity problem, we utilized an iterative 3SLS estimation method. Results show that consumer incomes are a major determinant of tropical fresh fruit import demand and most of the tropical fresh fruit imports are luxury commodities. U.S. consumers have a preference for Guatemalan and Costa Rican bananas, Costa Rican and Honduras pineapples, and Ecuador and Mexican mangoes. A competitive relationship exists between bananas from Ecuador and Colombia, Ecuador and...

A Spatio-temporal Model for Agricultural Yield Prediction
Provedor de dados: 31
Autores: Tokovenko,   Oleksiy; Dorfman,   Jeffrey H.; Gunter,   Lewell F.
The paper presents a spatio-temporal statistical model of agricultural yield prediction based on spatial mixtures of distributions. The proposed method combines several hierarchical and sequential Bayesian estimation procedures that allow the general problem to be addressed with a series of simpler tasks, providing the required flexibility of the model while decreasing the complexity associated with the large dimensionality of the spatial data sets. The data used for the study are 1970 - 2009 annual Iowa state county level corn yield data. The spatial correlation hypothesis is studied by comparing the alternative models using the posterior predictive criterion under squared loss function.

A Statistical Algorithm for Estimating Chlorophyll Concentration in the New Caledonian Lagoon
Provedor de dados: 5
Autores: Wattelez, Guillaume; Dupouy, Cecile; Mangeas, Morgan; Lefevre, Jerome; Touraivane,; Frouin, Robert.
Spatial and temporal dynamics of phytoplankton biomass and water turbidity can provide crucial information about the function, health and vulnerability of lagoon ecosystems (coral reefs, sea grasses, etc.). A statistical algorithm is proposed to estimate chlorophyll-a concentration ([chl-a]) in optically complex waters of the New Caledonian lagoon from MODIS-derived remote-sensing reflectance (R-rs). The algorithm is developed via supervised learning on match-ups gathered from 2002 to 2010. The best performance is obtained by combining two models, selected according to the ratio of R-rs in spectral bands centered on 488 and 555 nm: a log-linear model for low [chl-a] (AFLC) and a support vector machine (SVM) model or a classic model (OC3) for high [chl-a]....

A stem-cell ageing hypothesis on the origin of Parkinson&amp;#x27;s disease

Autores: Andr&amp;#xe9; Valente; Jorge Sousa; Tiago Outeiro; Lino Ferreira.
A transcriptome-wide blood expression dataset of Parkinson&amp;#x2019;s disease (PD) patients and controls was analyzed under the hypothesis-rich mathematical framework. The analysis pointed towards differential expression in blood cells in many of the processes known or predicted to be disrupted in PD. We suggest that circulating blood cells in PD patients can be in a full-blown PD-expression state. We put forward the hypothesis that sporadic PD can originate as a case of hematopoietic stem cell/differentiation process expression program defect and suggest this research direction deserves further investigation.

A Stochastic Differential Equation for Modeling the “Classical” Probability Distributions
Provedor de dados: 31
Autores: Hertzler,   Greg.
Stochastic differential equations are a flexible way to model continuous probability distributions. The most popular differential equations are for non-stationary Lognormal, non-stationary Normal and stationary Ornstein-Uhlenbeck distributions. The probability densities are known for these distributions and the assumptions behind the differential equations are well understood. Unfortunately, the assumptions do not fit most situations. In economics and finance, prices and quantities are usually stationary and positive. The Lognormal and Normal distributions are nonstationary and the Normal and Ornstein-Uhlenbeck distributions allow negative prices and quantities. This study derives a stochastic differential equation that includes most of the classical...

A strategy for workplace health promotion on German dairy farms
Provedor de dados: 111
Autores: Jakob, Martina Carola; Thinius, Maxi.
Studies across the globe have shown that at least 3 out of 5 milkers experience pain in the musculoskeletal system (MSS), mostly in the upper extremities (DOUPHRATE et al., 2014, JAKOB, 2011, KOLSTRUP, 2012, PINZKE, 2003, TUURE &amp; ALASUUTARI, 2009, KAUKE et al., 2010, THINIUS, 2012). The World Health Organisation (WHO) defines health as a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity. It is well known that dairy farming, and milking in particular is coupled with several risk factors for developing musculoskeletal disorders (KOLSTRUP, 2012). Technical measures seem to be insufficient to avoid physical overload. Therefore a more comprehensive approach seems to be necessary. In this study, four...

A Structural Analysis of Contractual Innovations within the CIS Milk Industry
Provedor de dados: 31
Autores: Jackson,   Elizabeth; Gorton,   Matthew; White,   John.
Utilising primary survey data, this paper evaluates the relationships between a set of supplier development strategies and performance within the milk industry in Armenia and Ukraine. Improving supplier performance is a critical task for the dairy industry in the Former Soviet Union as, during the 1990s both the quantity and quality of agricultural output deteriorated sharply. Fragmented supply chains led to high transaction costs and, in some cases, market failure. Drawing on the work of Krause et al. (2000) and Doney and Cannon (1997), a theoretical framework is presented that proposes that, either directly or indirectly, supplier assessment strategies, supplier incentives, competitive pressure, direct involvement, and trust between buyers and sellers,...

A Structural Equation Model of the Factors Influencing British Consumers’ Behaviour towards Animal Welfare
Provedor de dados: 31
Autores: Toma,   Luiza; McVittie,   Alistair; Hubbard,   Carmen; Stott,   Alistair W.
Results of national and pan-European consumer surveys and the growth in the demand for so-called “animal friendly” food products suggest that consumers within the European Union show a high level of concern for the welfare of farm animals. This paper analyses the determinants of British consumers’ behaviour towards animal welfare using structural equation models (SEM) with observed and latent variables. SEM is a statistical technique for testing and estimating relationships amongst variables, using a combination of statistical data and qualitative causal assumptions. We used a data set collected in 2005 through face-to-face interviews of 654 consumers in England. We analysed the range of statements in existing literature on consumers’ behaviour towards...

This case study on the former Rice Growers Association (RGA) analyzes the effects of a variety of business decisions and market changes, relative to the ongoing Farmers’ Rice Cooperative (FRC). Interview and survey findings reveal that many respondents felt RGA’s Board of Directors was passive and, despite its large size, lacked the necessary expertise to direct management and represent the best interest of the broader cooperative membership. In the midst of challenging market conditions, RGA’s management teams were accused of making a number of poor business decisions that led to significant financial stress and the eventual dissolution of the firm.

A study of the phase instability of quasi-geostrophic Rossby waves on the infinite beta-plane to zonal flow perturbations
Provedor de dados: 5
Autores: Marie, Louis.
The problem of the linear instability of quasi-geostrophic Rossby waves to zonal flow perturbations is investigated on an infinite beta-plane using a phase dynamics formalism. Equations governing the coupled evolutions of a zonal velocity perturbation and phase and amplitude perturbations of a finite-amplitude wave are obtained. The analysis is valid in the limit of infinitesimal, zonally invariant perturbation components, varying slowly in the meridional direction and with respect to time. In the case of a slow sinusoidal meridional variation of the perturbation components, analytical expressions for the perturbation growth rates are obtained, which are checked against numerical codes based on standard Floquet theory.

The Cretan tourism sector has been characterised by a large and rapid growth from 1970 to 2000 and has gone on the primary industry of the island. Despite the fact that this growth has seemed stagnant over the last few years, tourism is still of vital importance for the local economy. Agricultural industries are strongly linked with tourism activities and usually derive numerous benefits from them. Understanding tourists’ opinions and demands plays a crucial role in implementing appropriate and sustainable future agricultural offer strategies on the island in the future.

Elephant foot yam is traditionally cultivated on commercial scales in the states of Andhra Pradesh, Tamil Nadu, Kerala and West Bengal. The statistics on area, production and yield of this crop are not available in the literature and this paper has estimated the cost of cultivation, farm income measures and resource-use efficiency of the crop in these states, except West Bengal. The study has indicated the gross cost of cultivation as Rs 1,73,105, Rs 93,450 and Rs 1,68,032 per ha and the benefit-cost ratios as 1.38, 1.38 and 1.50 for elephant foot yam cultivation in Kerala, Andhra Pradesh and Tamil Nadu, respectively. The study has revealed excessive use of all NPK fertilizers in Kerala, indicating the need for rationalization in use of these inputs, while...

A Study on Staggered Public Procurement of Wheat in Punjab
Provedor de dados: 31
Autores: Sidhu,   M.S.; Singh,   Gaganjot.
Punjab is the second largest producer of wheat after Uttar Pradesh in the country but the state’s share in contribution to the central pool is maximum. The study has brought out that the marketed surplus of wheat was about 84 per cent with the selected farmers and about 96 per cent of the produce was sold during the post-harvest period. The study has revealed that per holding debt of the selected farmers, on an average, was Rs 1.71 lakh. About 99 per cent of wheat arrival was during the post-harvest period, from April to June in 2007-08. Wheat price in the months of April and May was almost equal to the MSP from 1997-98 to 2007- 08. During the lean period, there was a mixed scenario of the price. All this depended on the forces of the demand and supply. A...

Autores: Singh,   Mandeep; Chahal,   S.S.
The extent of adoption of various recommended production technologies and returns from wheat crop in Punjab have been studied for the years 2006-07, 2007-08 and 2008-09. The results reveal that the area under recommended varieties of wheat has decreased from 95.29 per cent in 2006-07 to 90.63 per cent in 2008-09. At the same time, it has been observed that a majority of the sample farmers grow wheat at recommended time by using recommended quantity of seed per acre. Although the percentage of farmers who treat the seed before sowing wheat crop has increased from 27.81 per cent in 2006-07 to 39.00 per cent in 2008-09, still a majority of the farmers do not follow this technology. It has been advocated by the PAU that zero tillage of wheat can save up to Rs...

Autores: Ozkan,O; Ahmet,C; Zafer,K.
Mitochondrial DNA (mtDNA) has been widely employed in phylogeographic and phylogenetic studies. In the present study, the genetic identification of the scorpion Androctonus crassicauda (Olivier, 1807) was carried out by using the 16S mitochondrial gene, since this scorpion represents the most important species in Turkey regarding scorpionism and antivenom production. Two genetic groups were found according to the sequence analysis results, while five different loci at the nucleotide level presented genetic variation in the 16S region when compared to a known A. crassicauda sequence data (GenBank, AJ277598). Nucleotide variations found in the current work constitute the first descriptive report for A. crassicauda. Moreover, future studies may enlighten the...

A Supply-Chain Analysis of Food Safety Standards Related to the Use of Wastewater for Irrigation of Crops
Provedor de dados: 31
Autores: Lagerkvist,   Carl Johan; Johansson,   Helena; Birol,   Ekin; Roy,   Devesh; Narrod,   Clare A.
Irrigation with raw or diluted wastewater is a widespread phenomenon, occurring on 20 million hectares across the developing world, especially in Asian countries, but also in peri-urban areas around almost every city of sub-Saharan Africa and in many Latin American cities. Growing urban populations and consequent increases in demand for food and water has spurred the use of sewage to water crops as this is, in many cases, the only form of irrigation for farmers who either lack clean water or for whom clean water is too expensive. Wastewater has high nutrient value and constitutes a reliable source (Scott et al., 2004). It is mostly used to produce cash crops (e.g. vegetables and cereals). For example, it has been estimated that in most parts of Sub-...

In 2003, Brazil was recognized as a pathogenic Newcastle Disease Virus (NDV) strain-free country for commercial poultry. This research was conducted in Brazil between December 2003 and March 2005 to verify the maintenance of this virulent NDV-free status. Serum samples from 5,455 flocks for commercial poultry farms were collected, comprising 81,825 broiler chickens. The farms were located in nine states of the country, grouped in three geographic regions. Serological evidence of NDV infection was detected in 28.8% of the surveyed farms. However, all fifteen viruses isolated and identified as Newcastle Disease Virus (NDV) were characterized as nonpathogenic strains, based on the Intracerebral Pathogenicity Index. These results showed that Brazil preserves...

Autores: Manouselis,   Nikos; Konstantas,   A.; Palavitsinis,   N.; Costopoulou,   Constantina; Sideridis,   Alexander B.
The role that information technology plays in today’s business activities has led to an  increase in firms using and/or deploying e-markets online. This development undoubtedly affects the agri-food sector, since a large number of agricultural firms are demonstrating or are expected to demonstrate e-commerce activities. This paper aims to provide an overview of the current status of agricultural e-markets in Greece, by presenting results from an analysis of 100 cases. Results indicate that Greek e-markets may  still have a rather low degree of sophistication, but they demonstrate a strong B2B orientation, as well as an outreach for international customer bases.

Provedor de dados: 5
Autores: Oliver, K. I. C.; Hoogakker, B. A. A.; Crowhurst, S.; Henderson, G. M.; Rickaby, R. E. M.; Edwards, N.r.; Elderfield, H.
The isotopic composition of carbon, delta C-13, in seawater is used in reconstructions of ocean circulation, marine productivity, air-sea gas exchange, and biosphere carbon storage. Here, a synthesis of delta C-13 measurements taken from foraminifera in marine sediment cores over the last 150 000 years is presented. The dataset comprises previously published and unpublished data from benthic and planktonic records throughout the global ocean. Data are placed on a common delta O-18 age scale suitable for examining orbital timescale variability but not millennial events, which are removed by a 10 ka filter. Error estimates account for the resolution and scatter of the original data, and uncertainty in the relationship between delta C-13 of calcite and of...

A systems approach to liveability and sustainability: Defining terms and mapping relationships to link desires with ecological opportunities and constraints
Provedor de dados: 31
Autores: de Chazal,   Jacqueline.
I offer a protocol for assessing the sustainability of liveability. This protocol draws on a framework developed to assess vulnerability, and offers two key pertinent features. These are (a) a capacity to incorporate multiple and shifting stakeholder values, and (b) a means of moving from expressions of liveability to underlying ecological attributes that deliver or constrain system change. The applicability of these features to both assessing the sustainability of liveability, and a reappraisal given system change are illustrated using data from a study site in the French Alps. The central place of values intrudes into liveability and sustainability so as to complicate the situation. Even so, the protocol presented here is able to ground the abstractions...

Aszőlő rügyfakadási időpontjának modellezése és előrejelzése növényvédelmi és gazdasági szempontból nélkülözhetetlen lépés a szőlőtermelésben. Tanulmányunkat öt fehérborszőlő-fajta (Chardonnay, Rajnai rizling, Hárslevelű, Pinot blanc és Szürkebarát), valamint ezek klónfajtáinak 2000 és 2004 között felvételezett adataival végeztük. Az ültetvények a Duna borrégión belül, a Kunsági borvidékhez tartozó Helvécián találhatóak. Számításainkhoz egy olyan matematikai modellt állítottunk fel, mely kis hibával megbecsüli a várható rügyfakadás napját. Amodell az általánosan használt kumulált hőösszegszámításon alapul, az optimalizálást pedig a becsült időpontok napokban számított hibájára végeztük. Az optimális bázishőmérsékletet 6 °C-ban állapítottuk meg. Amodell...

Magyarországon is teret hódít a biomassza villamos energia termelésére történő felhasználása. A tanulmány Magyarországon képződő szőlővenyige és fanyesedék biomassza-erőművi beszállításának lehetőségeivel foglalkozik. 2009-ben már öt hazai nagyerőműben tüzelnek a környező erdőgazdaságokból származó alapanyagot. Magyarországon rendkívül sok az energetikai célra hasznosítható szőlővenyige és fanyesedék, ami nem kerül hasznosításra, holott ezek erőművi beszállítása – számításaink alapján – 45 km-es szállítási távolság alatt már gazdaságos lehet. A tanulmány hangsúlyozza, hogy az említett melléktermékek erőművi eltüzelése – csekély jövedelemtermelő képessége miatt – jövedelemszerzés helyett inkább a „felesleges” melléktermékektől való megszabadulást, az...

A tanulmányban bemutatott takarmányárak és a pulykahús-előállítás jövedelme közötti rendkívül szoros kapcsolat elgondolkodtató, mert a takarmány – mint a legfontosabb inputtényező – árának változása vállalatcsoportok átrendeződését eredményezheti. A takarmányárak fokozatos és lassú ütemű emelkedése ugyan különböző költséggazdálkodási eszközökkel egy bizonyos pontig ellensúlyozható, de a jelen tanulmányban vizsgált időtartam alatt két ízben is tapasztalt rendkívül drasztikus mértékű takarmányár-emelkedés által okozott hatások kivédésére az ágazat szereplőinek nincsen eszköze. Amennyiben a jövőben is előfordulnak hasonló mértékű takarmányáremelkedések, akkor azok vállalati csődökkel kísért szerkezeti átrendeződést is okozhatnak az ágazatban....

A támogatások szerepe a magyar mezőgazdaságban
Provedor de dados: 31
Autores: Kovacs,   Gabor.
Az agrár- és vidékfejlesztési támogatások a világ számos országában igen jelentősek. Magyarországon a 2008-ban kifizetett támogatások a szektor által előállított bruttó hozzáadott érték közel 44 százalékát tették ki. Ezt a juttatást – egyfajta közvetett adóként – a fogyasztók, illetve a többi ágazat finanszírozza (jórészt az EU szintjén). Ezért folyamatosan célszerű vizsgálni, hogy az agrártámogatások által okozott torzulások (pl. a termelés fennmaradása versenyképtelen üzemekben, a termelési struktúra nemkívánatos változásai) kellően indokolhatók-e ökonómiai vagy más előnyökkel, illetve hogy ezek a célok hatékonyabb módon is elérhetők-e?

A precíziós tápanyagpótlási technológiával, a vizsgált táblák 50%-ánál tapasztalható anyagköltség-megtakarítás. Az anyagmegtakarítás mellett célszerű számolni a működési költségek növekedésével. A Szegedi Gabonakutató Kft. segítségével végzett szántóföldi kísérletek adatai alapján megállapítható, hogy kukoricatermelésnél 48,85% őszi gyomborítottság felett ökonómiailag indokolt a precíziós gyomirtás.   -----------------------------------   By applying precision nutrient supplementation rather instead of...

Megállapítható, hogy a globalizációval együtt járó modernizációs és életminőség-javító folyamatok a tradíciókat csak igen lassan és korántsem teljes egészében váltják fel. A táplálkozási kultúrában kettősség érvényesül, fokozatosan billentve a mérleget a korhoz igazodó étkezési szokások felé. Különösen értékesek ezek a tapasztalatok az ázsiai piacon kereskedelmi szándékkal megjelenők számára. Megállapítható, hogy miközben folyamatosan nő a fizetőképes középrétegek és a foglalkoztatottak, így a korszerűbb élelmezési szokásokkal megismerkedők száma, ez mind magasabb minőségi elvárásokkal párosul. A helyi adottságoktól függően ez a mérsékeltebben feldolgozott termékek iránti igényt, vagy éppen csúcsminőség megkövetelését jelentheti. Bizonyos, hogy folytatódik...

Autores: Kevin P. Johnson; Kimberly K. O. Walden; Hugh M. Robertson.
While next generation sequencing technology can produce sequences covering the entire genome, assembly and annotation are still prohibitive steps for many phylogenomics applications.  Here we describe a method of Target Restricted Assembly (TRAM) of a single lane of Illumina sequences for genes of relevance to phylogeny reconstruction, i.e. single copy protein-coding genes.  This method has the potential to produce a data set of hundreds of genes using only one Illumina lane per taxon.

About 30 benthic Prorocentrum species have been described, some of which producing okadaic acid and derivatives involved in diarrhetic shellfish poisoning. The western Caribbean has been extensively studied for benthic dinoflagellates associated with ciguatera, and fifteen Prorocentrum species were described from mangroves and coral reefs of Belize. In contrast, no study reported the diversity of this genus in the Eastern Caribbean, especially in the Lesser Antilles. This study adds to the biodiversity knowledge in Martinique Island by investigating one site of the Caribbean coast from 2010 to 2017. Sediment samples were collected each year in March and studied taxonomically. Identification was realized morphologically by scanning electron microscopy,...

A területhasználat változásai

Autores: Farkas,   Jeno Zsolt; Csatari,   Balint.
A mezőgazdasági termelést meghatározó tényezők – környezeti, gazdasági, tár¬sadalmi és politikai szempontból – jelentősen változtak az elmúlt öt évtizedben. Földrajzi elemzésünk eredményeként látható, hogy napjainkban átmeneti időszakban vagyunk, melyet jól definiálható trendek, a mezőgazdasági területek csökkenése és az élelmiszerek iránti kereslet növekedése határoznak meg, ezért hazánkban fontos feladat, hogy e körülmények között a KAP 2014 utáni reformjára felkészüljenek. Fontos, hogy olyan támogatási rendszer érvényesüljön, amely a környezetre ható és a területhasználatban jelentkező negatív folyamatokat új pályára állítja, vagyis fenntartható legyen. Magyarország területhasználati változásairól megállapítható, hogy az Európai Unió országaihoz hasonló...

A TÉSZ-en keresztüli értékesítés indokait és a TÉSZ tagok aktivitását kérdő¬íves felmérés alapján vizsgálva megállapítható, hogy a ZÖLD-TERMÉK Szövetkezetnél, valamint a MÓRAKERT Szövetkezetnél a TÉSZ a termelő számára is elfogadha¬tó mennyiségű áru átvételével, a beszállításkor mutatott rugalmassággal, a megbíz¬hatósággal és a pozitív személyes kapcsolatok meglétével ösztönzi tagjait a TÉSZ-en keresztüli értékesítésre. A rugalmas és gyors fizetési feltételek, valamint az érvé¬nyes szerződések további ösztönzést jelentenek. Az előbbieknél kevésbé fontos tényező az ár, a TÉSZ által nyújtott szaktanácsadás, valamint az egyéb szolgáltatások.A ZÖLD-TERMÉK Szövetkezetnél a tagok többsége rendszeresen vagy alkalomszerűen igénybe veszi az utóbbiakat.

A Theoretical Model of Optimal Compliance Decisions under Different Penalty Designs in Emissions Trading Markets
Provedor de dados: 31
Autores: Restiani,   Phillia; Betz,   Regina.
This paper employs a theoretical model to examine compliance incentives and market efficiency under three penalty types: the fixed penalty rate, which uses a constant marginal financial penalty; the make-good provision (quantity penalty), where each missing permit in the current period is to be offset with a ratio (restoration rate) in the following period; and a mixed penalty, which combines the two penalty types. Using a simple two-period model of firm's profit maximisation, we analyse compliance decisions and the efficient penalty level under each penalty type. Firms‟ compliance strategies are modelled as an irreversible investment in abatement measures and permit buying in the market. Our findings indicate that the penalty type does not affect...

A theory for the tissue specificity of BRCA1/2 related and other hereditary cancers
Provedor de dados: 17
Autores: Bernard Friedenson.
Women who inherit a defective BRCA1 or BRCA2 gene have risks for breast and ovarian cancer that are so high and seem so selective that many mutation carriers choose to have prophylactic surgery.   There has been much conjecture to explain such apparently striking tissue specificity.  All these suggestions share the assumption that some disabled function of normal tumor suppressor genes leads to a tissue specific cancer response.  Here the idea is proposed and tested that major determinants of where BRCA1/2 hereditary cancers occur are related to tissue specificity of the cancer pathogen, the agent that causes chronic inflammation or the carcinogen.  The target tissue may have receptors for the pathogen, become selectively exposed to an inflammatory process...

A Theory of Firm Decline
Provedor de dados: 31
Autores: Gian Luca,   Clementi; Cooley,   Thomas; Di Giannatale,    Sonia.
We study the problem of an investor that buys an equity stake in an entrepreneurial venture, under the assumption that the former cannot monitor the latter’s operations. The dynamics implied by the optimal incentive scheme is rich and quite different from that induced by other models of repeated moral hazard. In particular, our framework generates a rationale for firm decline. As young firms accumulate capital, the claims of both investor (outside equity) and entrepreneur (inside equity) increase. At some juncture, however, even as the latter keeps on growing, invested capital and firm value start declining and so does the value of outside equity. The reason is that incentive provision is costlier the wealthier the entrepreneur (the greater is inside...

A aquicultura brasileira é a segunda (destaque para o Chile) em produção sul-americana, apoiada basicamente nas cadeias de produção da tilapicultura e da carcinicultura. O Brasil produziu, em 2007, 95.691,0 toneladas de tilápia, o que representa 45% da produção da aquicultura continental. A aquicultura formada por pequenos e médios produtores vem mostrando, nos últimos anos, mudança nos sistemas de criação. Até a o final da década de 90, ela se baseava no sistema semi-intensivo em viveiros escavados e de barragens. A partir do ano de 2000, surge, com força, a tilapicultura em tanques-rede, principalmente em águas da União (grandes reservatórios de hidroelétricas e açudes da Região Nordeste). Esta mudança acarretou alterações na cadeia de produção, uma vez...

A time to change? The supply of climate mitigation products from land-use change in northern NSW
Provedor de dados: 31
Autores: Moss,   Jonathan; Cacho,   Oscar J.; Mounter,   Stuart W.
With the impending introduction of an Australian Carbon Pollution Reduction Scheme, farmers and landholders in rural Australia have increased opportunities to participate in the market. This includes the adoption of land-use change to sequester additional carbon in exchange for carbon credits and the production of a renewable energy source (biofuels). However, these land-use changes compete with existing farm enterprises and may contain significant transaction costs. Therefore it is necessary for the institutional arrangements to provide adequate incentives for landholders to adopt these land-use changes. This paper examines the potential supply of these land-use changes for climate mitigation from landholders in a northern NSW catchment. These results...

A Trade Area Analysis of Wisconsin Counties: Updated for 2010
Provedor de dados: 31
Autores: Deller,   Steven C.
For updated Trade Area Analysis (TAA) of Wisconsin counties we use the sales tax data as reported by the Wisconsin Department of Revenue for 2010. Only those counties that have elected to collect the optional county sales tax are included in the analysis. Because sales tax data are used one must keep in mind that the analysis focuses only on taxable sales and may not reflect the total level of activity in the county. Using Pull Factors and measures of Surplus and Leakage the relative strengths, and weaknesses, of local retail and service markets are identified. Changes in Pull Factors from 2005 to 2010 are provided to gain insights into growing and declining sectors. Finally, an update of simple Wisconsin retail market thresholds estimates (i.e., number of...

A Transportation Alliance of Environmental Horticulture Producers in Georgia:  Issues and Feasibility
Provedor de dados: 31
Autores: Stegelin,   Forrest E.; Mantilla,   Javier; Houston,   Jack E.; Thomas,   Paul A.; Chappell,   Matthew R.
Transportation and shipping costs of ornamental horticulture are 10% of total cost of production in Georgia.  With many small to medium sized producers using their own independent transportation system, methods to optimize vehicle operations are desired.  Will a transportation alliance reduce shipping costs, increase distribution efficiencies, and reduce carbon dioxide emissions among ornamental plants producers in Georgia?  The study shows alliances are not only feasible, they have average total cost savings of 9%, average total miles driven savings of 8%, average number of trucks savings of 8%, average driving hours savings of 15%, and average carbon dioxide emissions savings of 8%.

A Trend Deduction Model of Fluctuating Oil Prices
Provedor de dados: 31
Autores: Xu,   Haiyan; Zhang,   ZhongXiang.
Crude oil prices have been fluctuating over time and by a large range. It is the disorganization of oil price series that makes it difficult to deduce the changing trends of oil prices in the middle- and long-terms and predict their price levels in the short-term. Following a price-state classification and state transition analysis of changing oil prices from January 2004 to April 2010, this paper first verifies that the observed crude oil price series during the soaring period follow a Markov Chain. Next, the paper deduces the changing trends of oil prices by the limit probability of a Markov Chain. We then undertake a probability distribution analysis and find that the oil price series have a log-normality distribution. On this basis, we integrate the...

A turizmus szerepe a Mátravidéken
Provedor de dados: 31
Autores: David,   Lorant; Toth,   Geza.
A Mátra településeinek jó része társadalmi-gazdasági problémákkal küzd, melyeket jól jellemez az elvándorlás, a magas munkanélküliség, alacsony vállalkozássűrűség, illetve jövedelem. Az Észak-magyarországi Régióban végzett kutatásainkban már korábban megállapítottuk ezeket a tényeket. A Mátravidék fejlődésének egyik alapja lehetne az idegenforgalom/turizmus, de megállapítható, hogy kereskedelmi szálláshely-ellátottság tekintetében lakosságarányosan jelentősen elmarad a vidéki átlagtól, tehát fejlesztésekre van szükség. Véleményünk szerint elsősorban a meglévő 3 és 4 csillagos szállodák minőségi fejlesztését szükséges végrehajtani. Ha a Mátravidék turizmusa dinamikus fejlődésnek indul, a minőségi szálláshelyek férőhely-kapacitásának növelése is indokolt...

A TWO-STEP ESTIMATOR FOR A SPATIAL LAG MODEL OF COUNTS: THEORY, SMALL SAMPLE PERFORMANCE AND AN APPLICATION
Provedor de dados: 31
Autores: Lambert,   Dayton M.; Brown,   Jason P.; Florax,   Raymond J.G.M.
Several spatial econometric approaches are available to model spatially correlated disturbances in count models, but there are at present no structurally consistent count models incorporating spatial lag autocorrelation. A two-step, limited information maximum likelihood estimator is proposed to fill this gap. The estimator is developed assuming a Poisson distribution, but can be extended to other count distributions. The small sample properties of the estimator are evaluated with Monte Carlo experiments. Simulation results suggest that the spatial lag count estimator achieves gains in terms of bias over the aspatial version as spatial lag autocorrelation and sample size increase. An empirical example deals with the location choice of single-unit start-up...

A vizsgált jövedelmezőségi mutatók regressziós analízise révén igazolódott, hogy a forrásszerkezeti arányok jelentősen hatnak a jövedelmezőségre. Meghatározásra került továbbá egy olyan tőkeáttételi arány – tevékenységi irány és méretspecifi kusan –, melyről elmondható, hogy az azt meghaladó érték veszteséges gazdálkodással párosul. Megállapítható, hogy az optimális tőkestruktúra megteremtése érdekében első lépésben a saját források szerepének erősítésére szükséges törekedni, mindenekelőtt...

Autores: Robert Muetzelfeldt.
The aim of this document is to explore a unified approach to handling several of the proposed extensions to the SBML Level 3 Core specification.   The approach is illustrated with reference to Simile, a modelling environment which appears to have most of the capabilities of the various SBML Level 3 package proposals which deal with model structure.   Simile (http://www.simulistics.com) is a visual modelling environment for continuous systems modelling which includes the ability to handle complex disaggregation of model structure, by allowing the modeller to specify classes of object and the relationships between them.&amp;#xd;&amp;#xa;&amp;#xd;&amp;#xa;The note is organised around the 6 packages listed on the SBML Level 3 Proposals web page...

A unified deep-to-shallow water wave-breaking probability parameterization
Provedor de dados: 5
Autores: Filipot, Jean-francois; Ardhuin, Fabrice; Babanin, Alexander V.
Breaking probabilities and breaking wave height distributions (BWHDs) in deep, intermediate, and shallow water depth are compared, and a generic parameterization is proposed to represent the observed variability of breaking parameters as a function of the nondimensional water depth. In intermediate and deep water, where waves of different scales may have markedly different breaking probabilities, a BWHD as a function of wave frequency is proposed and validated with intermediate-depth and deep water observational data. The current study focuses on waves with frequencies between 0.55 and 3.45 times the peak frequency f(p). For the dominant frequency, the integration of the frequency-dependent BWHD provides a breaking probability that reproduces the known...

Autores: Sribir Sen.
Drug resistant bacterial pathogens are increasing in the environment due to multiple reasons. If any drug resistant pathogen grows in a host, the host will face death treat because there is no way to resist their growth in the host system. Eventuality is death in almost all cases. Reports on the mechanisms of drug resistance in bacteria are many. However, there is no solution for these cases. The present work is providing an important understanding to fight against drug resistant pathogens and that can be used in gastrointestinal diseases.

*Background:* &amp;#xd;&amp;#xa;&amp;#xd;&amp;#xa;Mendelian disorders are individually rare but collectively common, forming a &amp;#x22;long tail&amp;#x22; of genetic disease. More than 20 million people worldwide suffer from a disease in this long tail before the age of 25, with minorities and developing countries at highest risk and with the number of carriers far in excess of this figure. Importantly, the Jewish community&amp;#x2019;s campaign for universal Tay-Sachs screening shows that these incurable diseases can nevertheless be prevented if carrier status is known before conception. A single highly-accurate assay for the long tail of Mendelian disease would allow us to scale this successful campaign up to the general population, thereby improving...

A user-friendly database for Participatory Plant Breeding programs
Provedor de dados: 21
Autores: Rosenfeld, Simon; Parzies, Heiko; Grando, Stefania; Ceccarelli, Salvatore.
In a decentralized and participatory plant breeding (PPB) program, in contrast to conventional plant breeding, farmers select from a large number of genotypes over a number of cycles in several locations. As selection is for location-specific adaptation a PPB program based on, for example, four stages of selection, generates large, unbalanced data sets. With common spreadsheet software it is not possible, or it is at least very cumbersome to extract all the information, particularly the one that is related to genotype x environment (GE) interactions. Therefore, there is a need for an information system that makes it as easy as possible to retrieve and compare data over all given factors in the PPB-program. Due to a lack of education and financial resources...

Magyarország élelmiszer-gazdasági külkereskedelme az árciklus, és ezen belül elsősorban az árrobbanás nyertesei közé sorolható. Lényegesen javult az egyenleg a válság előtti időszakhoz képest, a gabona és olajos növények exportja a növekvő piaci áraknak köszönhetően ugrásszerűen emelkedett a 2007-2008. években. A többi ágazat képe alapján azonban már inkább a vesztesek körébe került Magyarország, elsősorban a húspiacon (kivéve a baromfiszektort), a tej és tejtermékek, valamint a gyümölcs- és zöldségtermelés csökkenő nemzetközi versenyképessége miatt.  Ha a főbb versenytársak élelmiszer-gazdasági külkereskedelmének alakulásával hasonlítjuk össze hazánkét, még vegyesebb a kép.

A tanulmány az aktív tanulás (Rural Action Learning, RAL) módszertani megközelítésének ismertetését követően bemutatja a Nyugat-dunántúli Régióban végzett, a regionális értékek és adottságok, helyi termékek ismeretét vizsgáló felmérés eredményeit. Elmondható, hogy a megkérdezettek jelentős hányada nem ismeri, hogy milyen növényeket termelnek, illetve milyen...

A vidéki hálózatok tevékenysége az Európai Unióban, kételyek és esélyek
Provedor de dados: 31
Autores: Feher,   Istvan; Kujani,   Katalin Olga.
A tagállamok cselekvési tervét és a felállított struktúrákat áttekintve megállapítható, hogy főleg azok az államok tudtak eredményes intézményrendszert kialakítani 2008 óta, akiknek önkéntesen hálózatba szerveződő csoportjai már korábban is működtek.  Számos tagállamban a hálózati koordináló feladatok ellátását külön kompetenciának tekintik, és speciális képzést indítanak a szakemberek felkészítésére. A képzett animátorok kulcsszereplői a hálózatok működtetésének. Feladatuk, hogy szervezői tevékenységük révén aktivizálják a hálózatok szereplőit, aktualizálják, mozgósítsák a már kialakult partneri kapcsolatokat, szervezzék a hálózaton belüli és kívüli tapasztalatcseréket, rendszeresen informálják a nemzeti és uniós szintű projektekről,...

Észak-Magyarország három megyéje közül Borsod-Abaúj-Zemplén megyé-ben a legjelentősebb a magánszállásadás szerepe, a vendéglátók 50,5%-a találha-tó itt, Hevesben 41,6%-a, miközben Nógrád megyében 7,9%-a. Észak-Magyarország magánszállás férőhelyeinek eloszlása a 2005-ös adatokat vizsgálva területileg meglehetősen egyenlőtlen. A magánszálláshelyeken belül a 2005-ös adatok alapján a falusi szállásadás szálláshelyei 58%-ot tesznek ki, mellyel a régió eltér az országos megoszlástól. A legtöbb mutató vonatkozásában megállapítottuk, hogy a régió megyéinek falusi szállásadással, illetve magánszállásadással rendelkező települései társadalmi-gazdasági fejlettsége, illetve folyamatai sok tekintetben kedvezőtlenebbek az ilyen szállásadással rendelkező települések...

A View Toward Sound Policy Initiatives Regarding Agricultural Alternative Fuels
Provedor de dados: 31
Autores: Dubiansky,   Vincent M.
Scientific understanding regarding causes of climate change is maturing. Earlier indications that atmospheric CO2 is the primary cause have been challenged by recent studies. Evidence against anthropogenic global warming is mounting. Subsidized alternative fuel initiatives may run out of support once political opinion aligns with scientific realities. First steps toward policy statements within professional organizations that reflect our current understanding of forces driving climate change are called for. We as farm or timberland managers, investors, lenders, appraisers or consultants in these fields should update our understanding. Agriculture’s potential contribution toward cost effective alternative fuel sources and energy independence is discussed.

A war-prone tribe migrated out of Africa to populate the world.
Provedor de dados: 17
Autores: Eduardo  Moreno.
Of the tribal hunter gatherers still in existence today, some lead lives of great violence, whereas other groups live in societies with no warfare and very little murder^1,2,3,4,5^. Here I find that hunter gatherers that belong to mitochondrial haplotypes L0, L1 and L2 do not have a culture of ritualized fights. In contrast to this, almost all L3 derived  hunter gatherers have a more belligerent culture that includes ritualized fights such as wrestling, stick fights or headhunting expeditions. This appears to be independent of their environment, because ritualized fights occur in all climates, from the tropics to the arctic. There is also a correlation between mitochondrial haplotypes and warfare propensity or the use of murder and suicide to resolve...

A western perspective on Kautilya's 'Arthasastra': Does it provide a basis for economic science?
Provedor de dados: 31
Autores: Tisdell,   Clement A.
In Arthasastra, Kautilya shows a knowledge of basic economics that had no parallels in Western economic thought until the publication of Adam Smith’s Wealth of Nations in 1776. Although the king was at the centre of the body politic in Kautilya’s time, Kautilya makes it clear that the king is bound by an implicit social contract and that the ultimate objective of the king, in economic and other affairs, should be to benefit his subjects. Their happiness or welfare should be the prime objective of State policy. As pointed out here, Kautilya’s conception of economics was superior to that of the Mercantilists and the Physiocrats. Given the central position of the Mauryan State in directing economic activity and providing security, the importance of adequate...

While free radicals and inflammation constitute major routes of neuronal injury occurring in neurodegenerative diseases, neither antioxidants nor nonsteroidal anti-inflammatory drugs (NSAIDs) have shown significant efficacy in human clinical trials. To explore the possibility that concurrent blockade of free radicals and PGE2-mediated inflammation might constitute a safe and effective therapeutic approach to certain neurodegenerative diseases, we have developed 2-hydroxy-5-[2-(4-trifluoromethylphenyl)-ethylaminobezoic acid (AAD-2004) as a derivative of aspirin. AAD-2004 completely removed free radicals at 50 nM as a potent spin trapping molecule and inhibited microsomal prostaglandin E synthase-1 (mPGES-1) with an IC50 of 230 nM. Oral administration of...

Autores: Nauta, Wytze J.; Cuijpers, Willemijn J.M.; Staps, J.J.M.; Scholberg, Johannes.
In Nederland zijn er nu ruim 1 miljoen biologische legkippen die jaarlijks bijna 300 miljoen eieren produceren maar ook 25.000 ton mest. De meeste legkippenhouders hebben zelf weinig grond en moeten de mest afvoeren. Het project ‘Kippenmest en Kringloop’ streeft er naar deze mest zo goed mogelijk in te zetten en te benutten binnen de biologische landbouw. Om de mest aantrekkelijker te maken voor bijvoorbeeld de akkerbouw is het belangrijk dat de mestkwaliteit en daarbij met name de verhouding tussen stikstof en fosfaat verbetert. In 2009 en 2010 zijn pilots uitgevoerd om het effect van aanpassingen in het kippenvoer op de mestkwaliteit te onderzoeken.

Abelhas generalistas (Meliponina) e o sucesso reprodutivo de Stryphnodendron pulcherrimum (Fabales: Mimosaceae) com florada em massa na Mata Atlântica, BA
Provedor de dados: 82
Autores: Monteiro,Daniela; Ramalho,Mauro.
It is controversial the role played by Meliponina bees in the pollination of mass flowering trees with small generalized flowers (FMPG), very common group of trees in the tropical forest canopy. The species richness and relative abundance of flower visiting insects of the mass flowering tree Stryphnodendron pulcherrimum were measured to test the hypothesis of tight ecological association between these generalist bees and FMPG and to evaluate the effect of this relationship upon the reproductive success variation among tree crowns. The flower visiting insects were sampled on 10 flowering tree crowns at the Atlantic Rainforest in southern Bahia. Altogether, 553 visiting insects were collected during the flowering period of S. pulcherrimum: 293 (52%)...

Ability of Allium cepa L. root tips and Tradescantia pallida var. purpurea in N-nitrosodiethylamine genotoxicity and mutagenicity evaluation
Provedor de dados: 42
Autores: Rainho,Claudia R. de; Kaezer,Andréa; Aiub,Claudia A.F.; Felzenszwalb,Israel.
N-nitroso compounds, such as N-nitrosodiethylamine (NDEA), can be formed by the reaction of secundary amines with nitrosating agents, and are suspected to be involved in tumors in humans. NDEA has been considered a weak carcinogen in genotoxic assays probably due to the inefficient nitrosamine activation system that is used and/or to the efficient repair system. In this work, we evaluated the sensibility of Allium cepa L. root tips and Tradescantia stamen hair mutation assay (Trad-SH) using Tradescantia pallida var. purpurea for NDEA (0.1; 0.5; 5 and 25mM) genotoxicity and mutagenicity induction. Allium cepa L. was treated with different NDEA concentrations for 3h, for 3 consecutive days, including negative control (distilled water) and positive control...

Abiotic correlates of temporal variation of Hypsiboas leptolineatus (Amphibia: Hylidae)
Provedor de dados: 103
Autores: Hiert,Cristiane; Moura,Mauricio Osvaldo.
Studies of anuran population dynamics are key to uncovering the mechanisms responsible for temporal fluctuations in abundance and those that shape population structure. Population structure and population fluctuations can result from species specific demographic and behavioral characteristics, reproductive microhabitat availability (which is influenced by local environment and climate), as well as from responses to populations of other, sympatric species. In view of this, our study aimed to ascertain the temporal trends in a population of Hypsiboas leptolineatus, to describe how abundance changes between seasons, and to uncover the effects of environmental variables in shaping seasonal variations in abundance. Although H. leptolineatus occurs throughout...

Abiotic gradients drive floristic composition and structure of plant communities in the Monte Desert
Provedor de dados: 97
Autores: ACEBES,PABLO; TRABA,JUAN; PECO,BEGOÑA; REUS,MARÍA L; GIANNONI,STELLA M; MALO,JUAN E.
Defining plant communities in desert zones is difficult due to large scale homogeneity and small scale heterogeneity, thus making provision of systematic information for conservation decisions problematic. We analysed plant communities of the most arid sector of Monte Desert for structure, plant composition and environmental variables. Small-scale variables such as slope, rock cover, bare ground and litter, as well as large-scale ones such as species diversity, composition and similarity within and between sites were included. Analyses of floristic composition showed the difficulty of segregating distinct communities due to high internal heterogeneity and overlap between the different sites. Only mesquite woodlands, a community situated at the extreme of...

Autores: Mattos,DE; Cintra,JR; Mattos,CC Brandão de; Nakashima,F; Silva,RCMA; Moreira,HW; de Mattos,LC.
Diseases resulting from Helicobacter pylori infection appear to be dependent on a host of genetic traits and virulence factors possessed by this microorganism. This paper aimed to investigate the association between the ABO histo-blood groups and H. pylori cagA infections. Genomic DNA samples (n = 110) of gastric biopsies obtained from patients with endoscopic diagnosis of peptic ulcers (n = 25) and chronic active gastritis (n = 85) were analyzed by PCR using specific primers for the cagA gene. Of the samples, 66.4% (n = 73) tested positive and 33.6% (n = 37) negative for the gene. The cagA strain was predominant in peptic ulcers (n = 21; 84.0%) compared with chronic active gastritis (n = 52; 61.2%) (p = 0.05; OR 3.332; 95% CI: 1.050-10.576). Additionally,...

Autores: Silva,Marcos Aurélio Santos da; Siqueira,Edmar Ramos de; Teixeira,Olívio Alberto.
O uso de técnicas de análise multivariada para avaliação espacial exploratória de dados agregados por áreas rurais tem se mostrado útil na caracterização e tipologia territorial. Ganha destaque nesta tarefa a abordagem conexionista, em especial a rede neural não supervisionada do tipo Mapa Auto-Organizável (MAO), ao agregar funções de análise de agrupamentos e de visualização de dados. Este trabalho estudou a capacidade da rede MAO no processo de avaliação exploratória de dados oriundos de múltiplas fontes para fins de determinação de agregados locais no Território Rural Centro-Sul de Sergipe (TRCSS). Os resultados evidenciaram que, apesar de homogêneo, o TRCSS apresenta subgrupos territoriais com diferenças significativas para as variáveis estudadas.

We assess how different certification standards address Aboriginal issues in Canada, augmenting current legislation related to Aboriginal issues. The benefits from forest certification and the obstacles to its adoption by the Aboriginal community are also reviewed. We conclude that it would take significant effort, time, and resources to achieve widespread Aboriginal adoption of forest certification.

Abrupt climate changes of the last deglaciation detected in a Western Mediterranean forest record
Provedor de dados: 5
Autores: Fletcher, W. J.; Goni, M. F. Sanchez; Peyron, O.; Dormoy, I.
Abrupt changes in Western Mediterranean climate during the last deglaciation (20 to 6 cal ka BP) are detected in marine core MD95-2043 (Alboran Sea) through the investigation of high-resolution pollen data and pollen-based climate reconstructions by the modern analogue technique (MAT) for annual precipitation (P-ann) and mean temperatures of the coldest and warmest months (MTCO and MTWA). Changes in temperate Mediterranean forest development and composition and MAT reconstructions indicate major climatic shifts with parallel temperature and precipitation changes at the onsets of Heinrich stadial 1 (equivalent to the Oldest Dryas), the Bolling-Allerod (BA), and the Younger Dryas (YD). Multi-centennial-scale oscillations in forest development occurred...

Abschätzung der Wertschöpfungspotenziale im ländlichen Raum durch Biokraftstoffe am Beispiel Nordrhein-Westfalens
Provedor de dados: 31
Autores: Breuer,   Thomas; Holm-Muller,   Karin.
To enhance the use of biofuels is stated priority of EU and German energy policy. Reasons given for this priority inter alia include positive income effects for the rural areas. This paper uses the example of North Rhine-Westphalia to investigate rural areas’ possibilities to profit from the added value of bio fuel production. It is shown that the main channel of income generation is based on stabilized demand for agricultural products. Taking into account recent policy shifts in Germany there remain few chances to participate in the added value of downstream production steps. In addition, due to considerable support for biogas plants maize production considerably reduces areas consecrated to bio fuel production.

Absolute Potentials of Standard Reference Electrodes at 25 C
Provedor de dados: 17
Autores: Raji Heyrovska.
Aqueous standard redox potentials are conventionally referred to that of the standard hydrogen electrode (SHE) as zero (IUPAC definition), in the absence of the knowledge of its absolute value. Recently, the author obtained its value (4.20 V) from a newly found linear dependence of redox potentials on ionization potentials. This has enabled now to express the potentials of standard reference electrodes in terms of the absolute values.

Absorção, acúmulo e exportação de macronutrientes no milho doce cultivado em condições de campo
Provedor de dados: 64
Autores: Borin,Ana Luiza Dias Coelho; Lana,Regina Maria Quintão; Pereira,Hamilton Seron.
O milho doce é uma hortaliça voltada para o processamento industrial, é ainda pouco difundido para o consumo in natura no Brasil, talvez pelo restrito número de cultivares adaptadas ao clima tropical. Os estudos sobre as práticas de manejo mais adequadas, incluindo a dinâmica de absorção de nutrientes pela cultura, ainda são inexistentes. Portanto, neste trabalho, objetivou-se determinar a absorção, o acúmulo e a exportação de nutrientes no milho doce cultivado em condições de campo. Utilizou-se o híbrido simples Tropical, em delineamento inteiramente casualizado, sendo o experimento constituído por nove épocas de coleta (9, 18, 27, 36, 45, 54, 63, 72 e 81 dias após a emergência) com quatro repetições. As plantas amostradas em cada época (tratamento) foram...

Absorção, fluxo no xilema e assimilação do nitrato em feijão-caupi submetido à salinidade
Provedor de dados: 124
Autores: Aragão,Rafael Magalhães; Silveira,Joaquim Albenísio Gomes; Silva,Evandro Nascimento; Lobo,Ana Karla Moreira; Dutra,Antônia Tathiana Batista.
Resumo O presente trabalho foi desenvolvido com o objetivo de avaliar qual etapa da aquisição de nitrato (absorção, fluxo no xilema ou redução assimilatória) é mais influenciada pela presença do NaCl em feijão-caupi. Plântulas com 12 dias de idade foram tratadas com NaCl 50 mM em solução nutritiva durante 4 dias e as avaliações realizadas sob duas condições ambientais contrastantes: dia típico (pleno sol) e dia completamente nublado (nublado). A salinidade afetou mais intensamente o fluxo da seiva e o fluxo de nitrato no xilema do que a transpiração sob as duas condições ambientais. Plantas tratadas com NaCl mostraram uma intensa redução na taxa de absorção de nitrato e na atividade da redutase de nitrato nas folhas, tanto em pleno sol como em dia nublado,...

Abundance and diversity of ammonia-oxidizing bacteria in relation to ammonium in a Chinese shallow eutrophic urban lake
Provedor de dados: 58
Autores: Qiu,Shanlian; Chen,Guoyuan; Zhou,Yiyong.
The measures of most-probable-number and restriction fragment length polymorphism analysis were used to analyze the abundance and diversity of ammonia-oxidizing bacteria in sediment of a Chinese shallow eutrophic urban lake (Lake Yuehu). Among the 5 sampling sites, ammonia concentration in interstitial water was positively proportional not only to the content of organic matter, but also to ammonia-oxidizing bacteria numbers (at a magnitude of 10(5) cells g-1 dry weight) in sediment significantly. Furthermore, the diversity of ammonia-oxidizing bacteria were determined by means of PCR primers targeting the amoA gene with five gene libraries created and restriction pattern analysis. The 13 restriction patterns were recorded with 4 ones being common among all...

Abundance and length structure of Brycon nattereri (Osteichthyes, Bryconidae), an endangered fish species in central Brazil
Provedor de dados: 3
Autores: Vitorino Júnior, Oscar Barroso; Lopes, Kelven Stella; Pelicice, Fernando Mayer.
Brycon nattereri is a threatened fish species restricted to small headwater rivers of the Paraná, São Francisco and Tocantins rivers. This species has been extirpated from many sites, and little is known about its ecology. In this sense, the present study investigated temporal variations in the occurrence, abundance and length structure of B. nattereri in the Dois Irmãos river, a small headwater river from the Tocantins river basin. Samples were taken monthly between January and November of 2009 and 2010. The studied site comprised a 4.5 km river stretch, sampled with an active fishing method (fly fishing). Individuals caught were counted, measured and returned immediately to the river. We caught 302 individuals along two years. Brycon nattereri was...

Abundance distribution of common and rare plant species of Brazilian savannas along a seasonality gradient
Provedor de dados: 39
Autores: Silva,Igor Aurélio; Cianciaruso,Marcus Vinicius; Batalha,Marco Antônio.
We examined the species abundance distribution (SAD) of plant communities in: (1) a wet grassland, waterlogged throughout most of the year; (2) a seasonal savanna, with an annual dry season; and (3) a hyperseasonal savanna, with alternating drought and waterlogging over the year. We searched for differences in the abundance distributions of all species, as well as of the common and rare species. We tested whether the SADs fitted the lognormal, log-series, power fraction, and random assortment models. We found that environmental constraints may reduce the evenness of plant communities and change the SADs in savannas. We observed a lognormal abundance distribution in the wet grassland and a random abundance distribution in the hyperseasonal cerrado. The SAD...

Provedor de dados: 76
Autores: Kasper,Carlos B.; Bastazini,Vinícius A. G.; Soares,José B. G.; Freitas,Thales R. O. de.
Between January 2007 and December 2010, the abundance of medium-sized mammals was studied, with special focus on the Molina's hog-nosed skunk, Conepatus chinga (Molina, 1782), at four locations in southern Brazil. In this study, transect line methodology was used to obtain data for Distance Analyses. Transects were traveled by car at night, searching with spotlights along the edges of secondary roads in agricultural landscapes. Along 1,811 km, we obtained 620 observations of 20 mammal species. The most common species was the exotic European hare, Lepus europaeus (Pallas, 1778); the highest abundance estimated for South America was observed in one of the study areas, where its density was estimated as 32 individuals/km². Carnivores were the most commonly...

Abundance of epigaeic arthropods in a Brazilian savanna under different fire frequencies
Provedor de dados: 103
Autores: Uehara-Prado,Marcio; Bello,Ayr de M.; Fernandes,Juliana de O.; Santos,Adalberto J.; Silva,Igor A.; Cianciaruso,Marcus V.
Fire is a major determinant of structure and dynamics in savannas, and the rapid increase of human activities in this biome has changed the natural burning regime. The effects of fire on the fauna of the cerrado (Brazilian savanna) are still poorly understood, and studies comparing sites frequently and infrequently burned are scarce. In this study, the abundance of epigaeic arthropod orders and trophic guilds was assessed in cerrado sites located in the Brazilian Central Plateau that were subjected to three burning frequencies: frequent (HighFi), intermediary (MidFi), and infrequent (LowFi). In general, we found a positive relationship between the abundance of epigaeic arthropods and fire frequency. When arthropods were analyzed by orders, the abundance of...

Abundance of the excavating sponge Cliona delitrix in relation to sewage discharge at San Andrés Island, SW Caribbean, Colombia
Provedor de dados: 20
Autores: Chaves-Fonnegra, A.; Zea, S.; Gómez, M.L.
It is known that the encrusting and excavating Caribbean sponge Cliona delitrix may increase its abundance near sources of sewage. To ascertain whether its current conspicuousness in leeward reefs of San Andrés Island (SW Caribbean, Colombia) is related to organic pollution from local raw sewage discharges, quantitative data on density and cover of this sponge and other benthic components was obtained from belt and line transects at seven stations along the shallow (5-10 m deep) terrace. Coral mucus was sampled to quantify Escherichia coli bacteria, as an approximate indicator of sewage plume influence on benthic biota. A negative multiplicative regression between amount of E. coli in coral mucus and distance from the main raw sewage outlet demonstrated...

“Academic Coaching” for Enhanced Learning, Higher Levels of Student Responsibility, and Greater Retention
Provedor de dados: 31
Autores: Barkley,   Andrew P.
The relationship between teachers and students has changed. Many writers have put forth hypotheses and ideas about how the current generation of students (Gen‐Y; the “Me Generation”) differs from previous generations. Others focus on teaching methods, course strategies, and technological tools that are effective in the new environment. The objective of this research is to investigate the possibility of “academic coaching” for enhanced student responsibility, higher levels of learning, and greater retention. The concept of “academic coaching” refers to a relationship between teachers and students that is proactive, responsive to student learning outcomes, and committed to student success. The teacher/learner relationship becomes less like a formal...

Acanthifoliosides, minor steroidal saponins from the Caribbean marine sponge Pandaros acanthifolium
Provedor de dados: 20
Autores: Regalado, E.L.; Jiménez-Romero, C.; Genta-Jouve, G.; Tasdemir, D.; Amade, P.; Nogueiras, C.; Thomas, O.P.
Seven novel steroid glycosides, acanthifoliosides A-F (1-6) and the methyl ester of 6 (7), were isolated from the marine sponge Pandaros acanthifolium as minor components. Acanthifoliosides are characterized by a rare C-15 and C-16 oxidized D ring which was previously found in saponins produced by starfishes. Very uncommon is the presence of additional sugar residues at C-15 or C-16. Their structures were determined on the basis of extensive spectroscopic analyses, including two-dimensional NMR and HRESIMS data. The absolute configurations of the aglycones were assigned by comparison between experimental and TDDFT calculated CD spectra of 1, whereas the absolute configurations of the monosaccharide units were determined by chiral GC analyses of the acid...

Provedor de dados: 14
Autores: OLIVEIRA, M. N. de; XAVIER, J. H. V.; ALMEIDA, S. C. R. de.
Este artigo apresenta os resultados de uma ação coletiva para aquisição de um tanque de resfriamento de leite, encarado inicialmente por um grupo de 20 assentados do PA Santa Clara Furadinho, em Unaí, MG, como forma de inserção favorável na dinâmica do desenvolvimento local. Foram acompanhados mensalmente, por cinco anos agrícolas, dados técnicos, econômicos e sociais de três agricultores assentados desse grupo. Houve aumento nas receitas e despesas dos lotes, reposicionamento da utilização da mão-de-obra familiar e diminuição da atividade agrícola. A intensidade da atividade pecuária leiteira sinaliza uma especialização da atividade produtiva nesse assentamento.

O presente trabalho teve o objetivo de analisar os efeitos do enxofre e da chuva ácida simulada sobre a estrutura foliar do feijoeiro (Phaseolus vulgaris L), nos aspectos morfoanatômicos, teores de clorofila a, b,  total e feofitina. As plantas-controle sofreram simulações de chuva com pH 6,0 e as plantas-teste sofreram simulação de chuva ácida com pH 3,0. As concentrações de clorofila a, b e total diminuíram no estádio de floração (R6). Já, no estádio R7, onde surgem as primeiras vagens, os teores aumentaram, indicando possível resistência e/ou adaptação dos espécimes às simulações ácidas. O tratamento ácido afetou a concentração de clorofila que foi degradada por processos oxidativos sem a sua conversão em feofitina. Também se observou diminuição na...

Ação do trifluralin na micorrização e crescimento de plantas de amendoim (Arachis hypogaea)
Provedor de dados: 87
Autores: Peixoto,M.F.S.P.; Borges,V.P.; Borges,V.P.; Peixoto,C.P.
O amendoim (Arachis hypogaea) é uma planta que durante as fases iniciais do seu desenvolvimento sofre mais intensamente a competição das plantas daninhas, prejudicando sensivelmente sua produção. Uma forma muito eficiente de solucionar esse problema é o uso do herbicida trifluralin; no entanto, seu uso pode prejudicar a micorrização, uma associação benéfica formada por fungos e raízes da planta hospedeira. Este trabalho objetivou avaliar o efeito do herbicida trifluralin e de duas espécies de fungos micorrízicos (Gigaspora margarita e Acaulospora scrubiculata) na micorrização e no crescimento inicial de plantas de amendoim.

O controle da leprose dos citros no Estado de São Paulo é realizado quase que exclusivamente com aplicações de acaricidas para o controle do ácaro vetor Brevipalpus phoenicis, as quais contribuem para o aumento dos custos de produção e podem afetar negativamente as populações de organismos benéficos. Portanto, o objetivo do trabalho foi avaliar, durante quatro safras, os efeitos de acaricidas indicados para o controle do ácaro B. phoenicis em citros convencional e orgânico sobre a evolução da leprose dos citros e sobre ácaros fitoseídeos. O experimento foi instalado em outubro de 2003, em pomar de laranja localizado no município de Reginópolis-SP. O delineamento experimental foi em blocos casualizados, estabelecendo-se os tratamentos, expressos em mL de...

Accelerated aging as vigor test for sunn hemp seeds
Provedor de dados: 65
Autores: Silva,Clíssia Barboza da; Barbosa,Rafael Marani; Vieira,Roberval Daiton.
ABSTRACT: This study aimed to determine the most appropriate method to assess the sunn hemp ( Crotalaria juncea L.) seed vigor in the accelerated aging test. Five seed lots from harvest 2007/2008 were evaluated for germination, vigor and seedling emergence in the field. Accelerated aging test was performed at 41°C during 48, 72 and 96 hours, with and without sodium chloride saturated solution. Then, the promising procedure was also performed for 2008/2009 and 2009/2010 harvests. In the traditional accelerated aging test, the no-uniform water acquisition by the seeds adversely affected results. Accelerated aging test with sodium chloride saturated solution is the most appropriate method to evaluate the physiological potential of sunn hemp seeds, and the...

Accelerated Productivity Growth Offsets Decline in Resource Expansion in Global Agriculture
Provedor de dados: 31
Autores: Fuglie,   Keith O.
Rapid increases in agricultural commodity prices during 2006-08 raised concerns that agricultural productivity growth may not be keeping up with increasing demand for agricultural commodities. ERS has developed a new index of total factor productivity (TFP) in global agriculture to provide a more comprehensive understanding of longrun sources of agricultural output growth. ERS research shows that the average rate of growth in global agricultural TFP has accelerated in recent decades and accounts for an increasing share of growth in agricultural production. Faster TFP growth has offset declining growth in agricultural land, labor, and other resources, although TFP growth across countries and global regions remains unevenly distributed.

Accelerating Africa's Structural Transformation Lessons from East Asia
Provedor de dados: 31
Autores: Gabre-Madhin,   Eleni Z.; Johnson,   Bruce F.
In most countries in sub-Saharan Africa at present, the majority of the population is engaged in agriculture, with economies in the very early stages of structural transformation - the process whereby a predominantly agrarian economy is transformed into a diversified and productive economy dominated by manufacturing and services. These countries are characterized by low levels of farm productivity, limited growth of non-farm employment and high rates of population growth. This paper focuses on the factors involved in fostering a country’s structural transformation. This process of transformation has many dimensions. Among these we emphasize interactions between four factors: increased agricultural productivity, rural industrialization, the expansion of...

Access Issues for Plant Breeders in an Increasingly Privatized World
Provedor de dados: 31
Autores: Lindner,   Robert K.
There is a growing trend to widespread privatisation of crop breeding, and there are grounds for expecting this trend to continue and even to accelerate. Possible consequences for Australian grain growers and the national interest of much greater private sector involvement in plant breeding are explored. Growing privatisation and commercialisation of plant breeding will lead to increased competition between plant breeders. While this increased competition has been at least partly driven by the potential for value creation, it also is likely to enhance value creation from plant breeding so long as there is adequate continuing investment in the capacity for plant breeding, and more particularly in productivity enhancing enabling technology. In the event of...

Access to Credit, Factor Allocation and Farm Productivity: Evidence From the CEE Transition Economies
Provedor de dados: 31
Autores: Ciaian,   Pavel; Falkowski,   Jan; Kancs,   d'Artis.
This paper analyses how farm access to credit affects farm input allocation and farm efficiency in the CEE countries. Drawing on a unique farm level panel data with 37,409 observations and employing a matching estimator we are able to control for the key source of endogeneity – unoberserved heterogeneity. We find that farms are credit constrained both in the short-run as well as in the long-run, but that credit constraint is asymmetric between inputs. Our estimates suggest that farm access to credit increases TFP up to 1.9% per 1000 EUR of additional credit. The use of variable inputs and capital investment increases up to 2.3% and 29%, respectively, per 1000 EUR of additional credit. Due to credit-financed investment in labour-saving farm equipment,...

Access to Dynamic Markets for Small Commercial Farmers: The Case of Potato Production in the Peruvian Andes
Provedor de dados: 31
Autores: Escobal D'Angelo,   Javier; Torero,   Maximo.
The purpose of this study is twofold. On one hand, the objective is to assess the impact of new and more complex contracting schemes, as opposed to traditional marketing channels, on small farmers’ welfare. On the other hand, the study explores which may be the critical factors that determine the small farmers’ participation in these institutional arrangements. In this context, two critical factors are stressed. The first one has to do with access to credit and the second one is the size of the agricultural plot. In order to examine the decision of farmers to access the dynamic markets, the paper follows the study of Lapar et al (2003). The paper also follows impact evaluation techniques to identify the differences in the performance of farmers with access...

Accessing rural finance: The rural financial market in Northern Vietnam
Provedor de dados: 31
Autores: Dufhues,   Thomas.
During the transition of the Vietnamese economy, adaptation of the financial system was one of the most challenging reforms. A major task of this reform was to expand the financial system’s outreach to the newly emerging private sector and household economies, especially in rural areas. Therefore, state-owned financial intermediaries such as the Vietnam Bank for Agriculture and Rural Development (VBARD) and the Vietnam Bank for the Poor (VBP) have been established. Despite general successes in terms of credit outreach, certain population groups, particularly the poorest, which are often identical to ethnic minorities, seem to have been bypassed by both banks. Furthermore, the strategy pursued by national rural financial policy has focused mainly on credit...

Autores: Fuller,   Frank H.; Beghin,   John C.; Fabiosa,   Jacinto F.; Mohanty,   Samarendu; Fang,   Cheng; Kaus,   Phillip J.
Using a world agricultural multimarket model, we analyze the consequences of enlargement of the European Union (EU) to include the Czech Republic, Hungary, and Poland for agricultural markets. We produce a market outlook through the year 2010 for two enlargement scenarios, which are based on different assumptions regarding the restrictions on grain and dairy production in the acceding countries. In both scenarios, accession of the three Central and Eastern European countries (CEECs) leads to a permanent but moderate decrease in EU prices for virtually all commodities. For the three acceding CEECs, domestic prices increase dramatically. Their final consumption of agricultural products decreases in most instances, while production rises. Higher domestic...

The pre-acclimatization stage can be used to improve micropropagation protocols and increase the yield of produced plants. The influence of sucrose and photon flux density (PFD) levels on the acclimatization of in vitro-grown 'VR043-43' (Vitis vinifera x Vitis rotundifolia) grapevine rootstocks was evaluated. Rooted shoots were obtained from 4-week-old in vitro shoots cultivated in QL (Quoirin and Lepoivre, 1977) culture medium supplemented with 15, 30 and 45 g L-1 of sucrose. The experiment was kept in a 25 ± 2ºC growth room, under 16-h photoperiod and PFD of 18 µmol m-2 s-1 or 43 µmol m-2 s-1.

Accounting for Impact of Environmental Degradation in Agriculture of Indian Punjab
Provedor de dados: 31
Autores: Singh,   Joginder; Sidhu,   R.S.
Having witnessed a fast growth, the agriculture in Punjab has reached a plateau. To sustain even the existing level, the costs are increasing and natural resources are being depleted due to overuse. This study has examined the use of certain resources and its impact on the cost of production. The data have been collected from different primary and secondary sources. The fast increase in area under rice and wheat appears to be unsustainable due to the fast decline in water table. Therefore, the cost of pumping out water with electricity has been going up, shortage of electric power has resulted in increase in the number of electric and diesel tubewells, further escalating the cost of production. The replenishment of soil health due to depleting macro and...

Accounting for Product Substitution in the Analysis of Food Taxes Targeting Obesity
Provedor de dados: 31
Autores: Miao,   Zhen; Beghin,   John C.; Jensen,   Helen H.
We extend the existing literature on food taxes targeting obesity. First, we incorporate the implicit substitution between sugar and fat nutrients implied by a complete food demand system and by conditioning on how food taxes affect total calorie intake. Second, we propose a methodology that accounts for the ability of consumers to substitute leaner low-fat and low-sugar items for rich food items within the same food group. This substitution is integrated into a demand system in addition to substitution among food groups. Simulations of a tax on added sugars show that the impact of the tax on consumption patterns is understated and the effect on welfare loss overstated when abstracting from this substitution within food groups.

Accounting for Respondent Uncertainty to Improve Willingness-to-Pay Estimates
Provedor de dados: 31
Autores: Moore,   Rebecca; Bishop,   Richard C.; Provencher,   Bill; Champ,   Patricia A.
In this paper we develop an econometric model of willingness to pay that integrates data on respondent uncertainty regarding their own willingness to pay. The integration is utility consistent and does not involve calibrating the contingent responses to actual payment data, and so the approach can “stand alone”. In an application to a valuation study related to whooping crane restoration, we find that this model generates a statistically lower expected WTP than the standard CV model. Moreover, the WTP function estimated with this model is not statistically different from that estimated using actual payment data, suggesting that when properly analyzed using data on respondent uncertainty, contingent valuation decisions can simulate actual payment decisions....

Accumulation and mobilization of lipids in relation to reproduction of yellowfin tuna (Thunnus albacares) in the Western Indian Ocean
Provedor de dados: 5
Autores: Zudaire, Iker; Murua, Hilario; Grande, Maitane; Pernet, Fabrice; Bodin, Nathalie.
Total lipid content and lipid class composition were analyzed in gonads, liver and white muscle of yellowfin tuna (Thunnus albacares) throughout ovary development to understand its reproductive allocation strategy and to assess the relation between female condition and reproduction. A total of 112 females were collected onboard purse-seiner in the Western Indian Ocean from January to March 2009, from June to July 2009, and from April to May 2010. Gonads were characterized by highly variable total lipid contents ranging from 5 to 27 μg mg−1 of wet weight (ww) with a predominance of neutral lipids, mainly triacylglycerols (TAG) and sterol- and wax-esters. The different lipid classes in gonads described an accumulative pattern through the maturity process...

In vineyards, if phosphate is applied both before planting and at intervals during growth without consideration of technical criteria, the soil P fractions may be increased and their proportions altered. This study was carried out to evaluate the accumulation of P fractions and the parameters of the adsorption isotherm in a sandy Typic Hapludalf soil in vineyards with a history of successive and excessive phosphate fertilization. In December 2010, two vineyards were selected, one 4 and the other 15 years old, in Urussanga, State of Santa Catarina (Brazil). Three trenches were dug in each area and soil was collected from the 0-5, 5-10 and 10-20 cm depth ranges. The soil samples were dried in a forced-air oven, sieved and subjected to chemical analyses, P...

Accuracy and Asymmetry of Corn, Soybean and Wheat Interval Forecasts
Provedor de dados: 31
Autores: Isengildina-Massa,   Olga; Sharp,   Julia L.; Zhang,   Jing; Campbell,   Wallace A.
This study evaluates the accuracy of USDA interval forecasts for corn, soybean, and wheat prices using Christoffersen’s (1998) tests for unconditional coverage, independence and conditional coverage adjusted for asymmetries in tail probabilities. The findings of this study demonstrate that due to uneven distribution of forecast misses around the interval, calibration of soybean price forecasts in several cases was rejected by basic coverage tests (suitable for symmetric intervals) but not rejected by the tests adjusted for asymmetry. Thus these forecasts were asymmetric but accurate. Symmetry was not a limiting assumption for corn and wheat interval forecast accuracy.

Accuracy of computational solvation free energies for neutral and ionic compounds: Dependence on level of theory and solvent model
Provedor de dados: 17
Autores: Sierra Rayne; Kaya Forest.
Gas to aqueous phase standard state (1 atm to 1 mol/L; 298.15 K) free energies of solvation ([DELTA]G^o^~solv~) were calculated for a range of neutral and ionic inorganic and organic compounds using various levels and combinations of Hartree-Fock and density functional theory (DFT) and composite methods (CBS-Q//B3, G4MP2, and G4) with the IEFPCM-UFF, CPCM, and SMD solvation models in Gaussian 09 (G09). For a subset of highly polar and generally polyfunctional neutral organic compounds previously identified as problematic for prior solvation models, we find significantly reduced [DELTA]G^o^~solv~ errors using the revised solvent models in G09. The use of composite methods for these compounds also substantially reduces their apparent [DELTA]G^o^~solv~...

Acerca del localismo ecuatoriano (Tema central).
Provedor de dados: 122
Autores: Ibarra C., Hernán.
En el Estado unitario centralizado ecuatoriano, las ideologías territoriales tuvieron una consolidación en el siglo XX, coexistiendo con versiones de estas ideologías en el plano local. Efectivamente, entre 7920 Y 7960 emergieron determinadas manifestaciones de identidad local cuyas huellas fueron la prensa local y las monografías de localidades y pueblos. Se produjo una reapropiación histórica y la construcción de símbolos identitarios que confluyeron en el particularismo local. Fueron representaciones sociales elaboradas por intelectuales de provincia que adaptaron al plano local 105 modos de construcción nacional y sustentaron el éxito relativo del Estado nacional en diseminar una ideología territorial y la aceptación de 105 símbolos patrios.

This work evaluated the effect of in vitro and in vivo treatment with ASA on the morphology of the red blood cells. Blood samples or Wistar rats were treated with ASA for one hour. Blood samples or animals treated with saline were used as control group. Blood smears were prepared, fixed, stained and the qualitative and quantitative morphology of red blood cells were evaluated under optical microscopy. Data showed that the in vitro treatment for one hour with ASA at higher dose used significantly (p&lt;0.05) modified the perimeter/area ratio of the red blood cells. No morphological alterations were obtained with the in vivo treatment. ASA use at highest doses could interfere on shape of red blood cells.

Achievements, challenges and perspectives of financial decentralization in Bulgaria
Provedor de dados: 31
Autores: Stoilova,   Desislava.
The process of gradual administrative and political decentralization in Bulgaria started in 1991, but the real financial decentralization process started in the beginning of 2003 with the adoption of a comparatively clear expenditure assignment and introduction of a transparent and predictable intergovernmental transfer system. Step by step, local governments have been given full control over some of the own-source revenues (local fees, service prices and revenues from municipal asset management) and limited control over the local tax levy.  This study is intended to examine and critically analyze the financial decentralization reform in Bulgaria, outlining the key achievements and basic weaknesses of expenditure assignment, local taxation and...

Achieving food security in China: Implications of WTO accession
Provedor de dados: 31
Autores: Duncan,   Ronald C.
The results of a three-year study of the implications of China's accession to the WTO for its agricultural sector and policy options to maximise the benefits of the trade reforms are reported. The most important message from the study is that macro-economic and other non-agriculture specific policies can do much to improve the outcome for rural households and thereby improve food security. These policies include the promotion of urban development in inland areas and gradual reform of monetary policy. However, agricultural policies need further reform, including abandoning of price support and regional self-sufficiency policies, reform of monopolistic agricultural marketing and distribution activities, and reform of the state grain storage system....

A key role for USAID and its partners is to identify how their resources can best contribute to increasing the capacity of the private and public sectors in Mali to scale up their investments, and increase the impact of those investments, in relation to the food security dimensions of availability, access, utilization and stability. To fulfill this role will involve identifying opportunities presented in the Malian agricultural sector investment plan (PNISA) to address critical needs in each of these dimensions, the types of investment that will best address the needs, and the set of resources and skills that will enable Malian organizations and entrepreneurs to implement those investments successfully and at scale. Even with increased resources, however,...

Autores: Abdulai,   Awudu; Diao,   Xinshen; Johnson,   Michael.
This study focuses on public investments and policy reforms for leveraging growth spillovers at the African regional level. A conceptual framework that is built on the endogenous growth theory and the new economic geography is presented first to gain a better understanding of the underlying theory and empirical evidence on regional integration and growth spillovers. In order to demonstrate the potential benefits from greater cross-border technology spillovers in Africa, as well as from trade liberalization and investment in infrastructure, results from ex-ante simulations using partial and general equilibrium models are then presented and discussed. Results indicate that sizeable regional spillover benefits can be obtained by permitting greater crossborder...

An integrated understanding of both social and ecological aspects of environmental issues is essential to address pressing sustainability challenges. An integrated social-ecological systems perspective is purported to provide a better understanding of the complex relationships between humans and nature. Despite a threefold increase in the amount of social-ecological research published between 2010 and 2015, it is unclear whether these approaches have been truly integrative. We conducted a systematic literature review to investigate the conceptual, methodological, disciplinary, and functional aspects of social-ecological integration. In general, we found that overall integration is still lacking in social-ecological research. Some social variables deemed...

Autores: Dalmago,Genei Antonio; Cunha,Gilberto Rocca da; Santi,Anderson; Pires,João Leonardo Fernandes; Müller,Alexandre Luiz; Bolis,Laise Maria.
O objetivo deste trabalho foi avaliar a influência da aclimatação ao frio sobre o dano causado pela geada em diferentes estádios fenológicos de genótipos de canola. Foram realizados cinco experimentos em ambiente controlado, em 2006, 2007 e 2008. Os fatores avaliados foram: genótipos, aclimatação (com; sem), intensidades de geada, estádios de desenvolvimento de plantas, regimes de aclimatação e regimes de geada. As variáveis avaliadas foram: queima de folhas, massa de matéria seca, estatura de plantas, duração de subperíodo, componentes de rendimento e rendimento de grãos. A aclimatação ao frio, antes da geada, resultou em menor queima de folhas e maior massa de matéria seca, em comparação a plantas não aclimatadas. As geadas foram prejudiciais a partir de...

Acordos regionais de livre comércio e o mercado de arroz no Brasil
Provedor de dados: 31
Autores: Alvim,   Augusto Mussi; Waquil,   Paulo Dabdab.
Este estudo identifica os efeitos dos novos acordos regionais de livre comércio sobre os produtores de arroz, no Brasil e nas demais regiões relevantes no mercado mundial. Para analisar os efeitos dos acordos comerciais, como, por exemplo, da ALCA, do MERCOSUL-UE e do MERCOSUL-CAN, desenvolve-se um modelo de alocação espacial e temporal utilizando-se um Problema de Complementaridade Mista (PCM). Em termos gerais, os maiores ganhos para os produtores brasileiros de arroz ocorreram com o acordo MERCOSUL-UE, quando a produção brasileira foi estimulada pelo redirecionamento das exportações argentinas e uruguaias para a UE. No entanto, em virtude das dificuldades nas negociações de livre comércio junto à UE, a segunda melhor opção, MERCOSUL-CAN, apresentou-se...

Acquiring plant features with optical sensing devices in an organic strip-cropping system
Provedor de dados: 21
Autores: Krus, Anne; van Apeldoorn, Dirk; Valero, Constantino; Ramirez, José Juan.
There is an increasing market for organic agriculture (Golijan &amp; Popovi\vs, 2016). However, the lack of attention for biodiversity and soil fertility of current practices is a pressing issue. The SUREVEG project (CORE Organic Cofund, 2018) therefore looks at strip-cropping in organic production and its implementation in intensive farming to improve soil fertility and biodiversity throughout Europe. The aim is to enhance resilience (Wojtkowski, 2008), system sustainability, local nutrient recycling, and soil carbon storage (Wang, Li &amp; Alva, 2010) among others. To counteract the additional labour of a multi-crop system, a robotic tool is proposed, which will operate upside down suspended from a wide-span mobile carriage. Within the project framework,...

Act to Save Groundwater in Punjab: Its Impact on Water Table, Electricity Subsidy and Environment
Provedor de dados: 31
Autores: Singh,   Karam.
The fall in water table in Punjab has been a serious issue. One of the main reasons for it has been the early transplanting of rice (before mid-June), which means severe withdrawal of groundwater, as the monsoon is still far away, temperatures are very high and evapo-transpiration rate (ETR) is maximum. On the initiative of the Punjab State Farmers Commission, “The Punjab Preservation of Sub Soil Water Act” (not to sow paddy nursery before May 10 and not to transplant paddy before June 10) was promulgated as an Ordinance in 2008 and encouraged by the response, it has been changed into an Act in March 2009. The time series and experimental data on transplanting pattern, water requirements rice, rainfall, monsoon recharge, groundwater behaviour and rice area...

Autores: Baldo,C; Ferreira,MJ; Lopes,DS; Izidoro,LFM; Gomes,AO; Ferro,EAV; Hamaguchi,A; Homsi-Brandeburgo,MI; Rodrigues,VM.
The damaging effects of neuwiedase, a non-hemorrhagic snake venom metalloproteinase from P-I class, on gastrocnemius muscle are studied herein. Following neuwiedase injection, ultrastructural alterations were detected early showing disarrangement of skeletal muscle fibers (characterized by discontinuity of Z lines), mitochondrial swelling, and disruption of plasma membrane and basal lamina. Degradation of skeletal muscle and the appearance of an amorphous substance, primarily composed of cellular debris, were noted after 24 hours. The presence of neuwiedase at the injection site (detected by immunocytochemistry) revealed highly specific labeling of myofibril components of damaged myocytes. In addition, proteolysis of muscle proteins assayed through...

Activation of phenylalanine ammonia lyase as a key component of the antioxidative system of salt-challenged maize leaves
Provedor de dados: 61
Autores: Gholizadeh,Ashraf; Kohnehrouz,B. Baghban.
Differential antioxidative activities were assessed in the leaves of two maize inbreds (A-180 and A-619) under salt stress and the subsequent recovery period. Total antioxidation test revealed that in both inbreds, this ability was sharply increased during stress period, but was slowly reverted back to the normal level during recovery. The enzymatic antioxidative analysis showed differential patterns in the activities of catalase, peroxidase and polyphenol oxidase in both maize inbreeds. Comparative analysis of the activity of phenylalanine ammonia lyase (PAL), a key enzyme at the gateway of propanoid biosynthetic pathway, suggested that propanoid compounds might be antioxidants of pivotal importance to the salt-challenged maize antioxidation system. As...

A prospective analysis of active Human Cytomegalovirus infection (HCMV) was conducted on 33 pediatric renal or hematopoietic stem cell post-transplant patients. The HCMV-DNA positive samples were evaluated for the prevalence of different gB subtypes and their subsequent correlation with clinical signs. The surveillance of HCMV active infection was based on the monitoring of antigenemia (AGM) and on a nested polymerase chain reaction (N-PCR) for the detection of HCMV in the patients studied. Using restriction analysis of the gB gene sequence by PCR-RFLP (Restriction Fragment Length Polymorphism), different HCMV strains could be detected and classified in at least four HCMV genotypes. Thirty-three pediatric recipients of renal or bone marrow transplantation...

The detailed morphology and internal structure of the Calabrian accretionary wedge and adjacent Eastern Sicily margin are imaged in unprecedented detail by a combined dataset of multi-beam bathymetry and high-resolution seismic profiles. The bathymetric data represent the results of 6 recent marine geophysical surveys since 2010 as well as a compilation of earlier surveys presented as a 2 arc-sec (60 m) grid. Several distinct morpho-tectonic provinces are identified including: the deeply incised Malta–Hyblean Escarpment, numerous submarine canyons, broad regions of relatively flat seafloor dominated by fields of sediment waves, the gently undulating anticlinal fold-and-thrust belts of the external Calabrian accretionary wedge and the adjacent portion of...

Active-passive synergy for interpreting ocean L-band emissivity: Results from the CAROLS airborne campaigns
Provedor de dados: 5
Autores: Martin, A. C. H.; Boutin, Jacqueline; Hauser, D.; Dinnat, E. P.
The impact of the ocean surface roughness on the ocean L-band emissivity is investigated using simultaneous airborne measurements from an L-band radiometer (CAROLS) and from a C-band scatterometer (STORM) acquired in the Gulf of Biscay (off-the French Atlantic coasts) in November 2010. Two synergetic approaches are used to investigate the impact of surface roughness on the L-band brightness temperature (Tb). First, wind derived from the scatterometer measurements is used to analyze the roughness contribution to Tb as a function of wind and compare it with the one simulated by SMOS and Aquarius roughness models. Then residuals from this mean relationship are analyzed in terms of mean square slope derived from the STORM instrument. We show improvement of new...

Autores: Petracci,Pablo F; Sotelo,Martín; Massola,Victoria; Carrizo,Martín; Scorolli,Alberto; Zalba,Sergio; Delhey,Valdemar.
El lobo marino de un pelo sudamericano (Otaria flavescens) se distribuye en la costa argentina desde Mar del Plata hasta Tierra del Fuego e Islas Malvinas con unas 70 colonias descriptas. En Buenos Aires existe una colonia reproductiva en Banco Culebra y tres no reproductivas en Mar del Plata, Quequén e Isla Trinidad. Esta última fue comunicada en 1952; desde ese año no se publicaron nuevos registros y en consecuencia la información citada posteriormente es confusa. En la presente nota se dan a conocer observaciones inéditas sobre su tamaño desde 1990. Se contaron entre 0 y 150 machos adultos y subadultos con variaciones según la época del año.

Actuarial Implication of Structural Changes in El Niño-Southern Oscillation Index Dynamics
Provedor de dados: 31
Autores: Chen,   Shu-Ling.
The influence of climate variability on agricultural production and financial risks faced by an individual or an institution has been the center of the public discussion in the recent years.  The changing weather patterns and environmental conditions could cause substantial unpredicted economic loss.  Failure to capture the changing climate would underestimate the insurance contract’s expected indemnity and further create a major obstacle for insurance sectors.  In this paper, we undertake a case study of El Niño-Southern Oscillation Index insurance for coastal Peru proposed by Skees.  We examined the behavior of El Niño dynamics and found El Niño indices are changing over time.  A class of generalized autoregressive conditional heteroskedasticity (GARCH)...

Acupuntura: histórico, bases teóricas e sua aplicação em Medicina Veterinária
Provedor de dados: 65
Autores: Scognamillo-Szabó,Márcia Valéria Rizzo; Bechara,Gervásio Henrique.
A acupuntura (AP) é uma técnica terapêutica empírica desenvolvida em uma cultura oriental e que utiliza pensamento mágico (linguagem pré-científica) em seu raciocínio. É uma terapia reflexa que utiliza a estimulação de pontos específicos do corpo com objetivo de atingir um efeito terapêutico ou homeostático. A AP preconiza que a saúde é dependente das funções psico-neuro-endócrinas, sob influência do código genético e de fatores extrínsecos como nutrição, hábitos de vida, clima, qualidade do ambiente, entre outros. O presente artigo faz uma breve revisão sobre a filosofia da AP, seus marcos históricos na China e no Ocidente, a história da AP veterinária no Brasil e no mundo. Também aborda a prática da AP, incluindo as formas de diagnóstico, a definição do...

Autores: Silva,Marcio de Oliveira; Bastos,Milena; Martins Netto,Eduardo; Gouvea,Nancy Alves de Lima; Torres,Alex Jose Leite; Kallas,Esper; Watkins,David I; Altfeld,Marcus; Brites,Carlos.
Acute HIV infection is rarely recognized as the signs and symptoms are normally unspecific and can persist for days or weeks. The normal HIV course is characterized by a progressive loss of CD4+ cells, which normally leads to severe immunodeficiency after a variable time interval. The mean time from initial infection to development of clinical AIDS is approximately 8-10 years, but it is variable among individuals and depends on a complex interaction between virus and host. Here we describe an extraordinary case of a man who developed Pneumocisits jiroveci pneumonia within one month after sexual exposure to HIV-1, and then presented with 3 consecutive CD4 counts bellow 200 cells/mm³ within 3 months, with no other opportunistic disease. Although...

Provedor de dados: 56
Autores: Silveira,E.A.; Lizardo,J.H.F.; Souza,L.P.; Stefanon,I.; Vassallo,D.V.
Chronic lead exposure induces hypertension in humans and animals, affecting endothelial function. However, studies concerning acute cardiovascular effects are lacking. We investigated the effects of acute administration of a high concentration of lead acetate (100 µΜ) on the pressor response to phenylephrine (PHE) in the tail vascular bed of male Wistar rats. Animals were anesthetized with sodium pentobarbital and heparinized. The tail artery was dissected and cannulated for drug infusion and mean perfusion pressure measurements. Endothelium and vascular smooth muscle relaxation were tested with acetylcholine (5 µg/100 µL) and sodium nitroprusside (0.1 µg/100 µL), respectively, in arteries precontracted with 0.1 µM PHE. Concentration-response curves to PHE...

Acute toxicity of birch tar oil on aquatic organisms
Provedor de dados: 21
Autores: Hagner, Marleena; Penttinen, Olli-Pekka; Pasanen, Tiina; Tiilikkala, Kari; Setälä, Heikki.
Birch tar oil (BTO) is a by-product of processing birch wood in a pyrolysis system. Accumulating evidence suggests the suitability of BTO as a biocide or repellent in terrestrial environments for the control of weeds, insects, molluscs and rodents. Once applied as biocide, BTO may end up, either through run-off or leaching, in aquatic systems and may have adverse effects on non-target organisms. As very little is known about the toxicity of BTO to aquatic organisms, the present study investigated acute toxicity (LC50/EC50) of BTO for eight aquatic organisms. Bioassays with the Asellus aquaticus (crustacean), Lumbriculus variegatus (oligochaeta worm), Daphnia magna (crustacean), Lymnea sp. (mollusc), Lemna minor (vascular plant), Danio rerio (fish),...

Autores: ManiRam,Prasad; Abhishek,Kumar; Diwakar,Mishra; Sunil K,Srivastav; Ajai K,Srivastav.
An acute toxicity test was performed by using a four-day static renewal test to determine the LC50 value of aqueous extract of Euphorbia royleana latex for the freshwater fsh, Heteropneustes fossilis. The LC50 values, their upper and lower confdence limits and slope functions were calculated. The LC50 values for aqueous extract of Euphorbia royleana latex at various exposure periods were 7.758 mg/L for 24 h, 5.847 mg/L for 48 h, 4.474 mg/L for 72 h and 3.090 mg/L for 96 h. The regression coeffcient showed that there was signifcant negative correlation between exposure time and different LC values. Hence, it is concluded that the concentration to produce toxicity of latex of Euphorbia royleana is comparable and close to the concentration to produce toxicity...

Perfluorooctane sulfonate (PFOS) is a persistent organic pollutant whose potential toxicity is causing great concern. In the present study, we used two crustaceans (_Daphnia magna_, _Siriella armata_), echinoid embryos (_Paracentrotus lividus_) and turbot (_Scophthalmus maximus L._) embryos and larvae to investigate the acute toxicity of this compound. The marine species _S. armata_ exhibited greater sensitivity than the freshwater species _D. magna_. In the 48-h acute toxicity test the median lethal concentration was 10.96 mg/L for _S. armata_ and 87.46 mg/L for _D. magna_. In the 96h toxicity test, turbot showed the lowest EC50 (0.155 mgL-1), whilst the EC50 for _S. armata_ was 7.92 mgL-1 which was approximately three times lower than that for sea urchin...

Provedor de dados: 96
Autores: Oliveira,Jackson Silva e; Ferreira,Reinaldo de Paula; Cruz,Cosme Damião; Pereira,Antônio Vander; Lopes,Fernando César Ferraz.
Foram avaliadas oito cultivares de milho para uso na forma de silagem. Os ensaios foram conduzidos em cinco localidades e a característica estudada foi a produção de matéria seca degradável no rúmen (kg/ha). Verificou-se a existência de interação genótipo × ambiente significativa para esta característica, demonstrando o comportamento diferencial das variedades para as variações ambientais. A variedade BR HT2X, apesar de ter apresentado elevada produtividade, foi a que mais contribuiu para a interação genótipo × ambiente, porém apresentou comportamento imprevisível, sendo, por isso, recomendada para situações de alto nível tecnológico, em que os efeitos de condições adversas podem ser minimizados. As variedades BR 205 e AGM 2010 destacaram-se pela alta...

Adaptación de métodos en microplacas para identificar mecanismos de resistencia en Tetranychus urticae Koch
Provedor de dados: 115
Autores: Cerna,Ernesto; Ochoa,Yisa; Badii,Mohammad; Landeros,Jerónimo.
Las pruebas bioquímicas son útiles para conocer la actividad y cantidad de enzimas responsables de la resistencia. En este estudio se recolectaron ácaros Tetranychus urticae Koch en campos productores de fresa del estado de Guanajuato, México. Se realizaron pruebas bioquímicas para determinar los mecanismos enzimáticos de resistencia, usando una línea susceptible de T. urticae como referencia y adaptando los métodos en microplacas, según lo describe Fersht para mosquitos. Una vez estandarizado el método se determinó el nivel de enzimas en ambas poblaciones. Se encontró que las oxidasas y las α y β esterasas tienen una mayor presencia en la población de campo; por tanto, son responsables de la resistencia a acaricidas de la población de T. urticae...

Adaptación de preferencias laborales en trabajadores informales calificados
Provedor de dados: 122
Autores: Castro Jaimes, Alberto.
Se propone que, bajo ciertas condiciones, la exclusión laboral y la precarización del trabajo pueden enfilarse en una elección aparente de empleos informales. Con base en un esquema de preferencias adaptativas se examinan los supuestos fundamentales del escape de la formalidad. Mediante una creativa metodología, se miden las preferencias laborales de una selección de técnicos profesionales, formales e informales. Las tendencias sugieren correlación significativa entre las preferencias y las variables de experiencia laboral. Se sugiere también que la satisfacción en el empleo está correlacionada con la sensación de seguridad en el mismo, con la trayectoria laboral y con la percepción de oportunidades.

Provedor de dados: 117
Autores: Berti,Marisol; Fischer,Susana; Wilckens,Rosemarie; Hevia,Felicitas; Johnson,Burton.
Flaxseed (Linum usitatissimum L.) is imported into Chile mostly for bread making and feed. Identification of genotypes best adapted for seed production in South Central Chile would facilitate producer’s decision. The objective of this study was to determine the adaptation and genotype x environment interaction of 16 flaxseed genotypes (including 10 from North American and six from Argentine sources) grown at 11 environments (defined as location-year) in Chile from 2003 to 2007. Genotype seed yield was above 5700 kg ha-1 for some environments indicating a high yield potential. According to the AMMI (Additive Main Effects and Multiplicative Interaction) and SREG (Sites regression) models the 11 environments were classified into four groups by the AMMI and...

Adaptation, Mitigation and “Green” R&amp;D to Combat Global Climate Change. Insights From an Empirical Integrated Assessment Exercise
Provedor de dados: 31
Autores: Bosello,   Francesco.
This work develops a framework for the analysis at the macro-level of the relationship between adaptation and mitigation policies. The FEEM-RICE growth model with stock pollution, endogenous R&amp;D investment and emission abatement is enriched with a planned-adaptation module where a defensive capital stock is built through adaptation investment. Within this framework the optimal path of planned adaptation, the optimal inter and intra temporal mix between adaptation, mitigation and investment in R&amp;D, and the sensitivity of a strategy to each other is identified. The major conclusions of this research show that adaptation, mitigation and R&amp;D are strategic complements as all concur together to the solution of the climate change problem; nonetheless...

Adaptation to Cold and Proteomic Responses of the Psychrotrophic Biopreservative Lactococcus piscium Strain CNCM I-4031
Provedor de dados: 5
Autores: Garnier, Matthieu; Matamoros, Sebastien; Chevret, Didier; Pilet, Marie-france; Leroi, Francoise; Tresse, Odile.
There is considerable interest in the use of psychrotrophic bacteria for food biopreservation and in the understanding of cold adaptation mechanisms. The psychrotrophic biopreservative Lactococcus piscium strain CNCM I-4031 was studied for its growth behavior and proteomic responses after cold shock and during cold acclimation. Growth kinetics highlighted the absence of growth latency after cold shock, suggesting a very high promptness in cold adaptation, a behavior that has never been described before for lactic acid bacteria (LAB). A comparative proteomic analysis was applied with two-dimensional gel electrophoresis (2-DE), and upregulated proteins were identified by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Both cold shock and cold...

Adapting natural resource management to climate change on the Olympic Peninsula
Provedor de dados: 17
Autores: Jessica Halofsky; David L. Peterson.
Climate change presents a major challenge to natural resource managers both because of the magnitude of potential effects of climate change on ecosystem structure, process, and function, and because of the uncertainty associated with those potential ecological effects. Concrete ways to adapt to climate change are needed to help natural resource managers take the first steps to incorporate climate change into management and take advantage of opportunities to balance the negative effects of climate change. We initiated a climate change adaptation case study at Olympic National Forest and Olympic National Park to determine how to adapt management of federal lands on the Olympic Peninsula to climate change. As a part of the case study process, we conducted a...

Adaptive Co-management Networks: a Comparative Analysis of Two Fishery Conservation Areas in Sweden
Provedor de dados: 7
Autores: Rova, Carl; Division of Social Science/Political Science Unit, Lule&amp;aring; University of Technology, Sweden; carl.rova@ltu.se.
Co-management constitutes a certain type of institutional arrangement that has gained increased attention among both policy makers and researchers involved in the field of natural resource management. Yet the concept of co-management is broad, and our knowledge about how different kinds of management structures affect the ability to deal with challenges pertinent to the commons is limited. One of these challenges is to foster an adaptive management process, i.e., a process in which rules are continuously revised and changed according to what is known about the ecological system. We aim to address the relationship between different kinds of co-management structures and adaptive management. To this end, we conducted a comparative case study of two Fishery...

Adaptiveness in Water Management Institutions in India: Nature and Impact
Provedor de dados: 31
Autores: Bhamoriya,   Vaibhav P.; Gandhi,   Vasant P.
The effective management of water resources is assuming enormous importance in India in the recent years. Sound water resource use is crucial for sustaining and raising food production, increasing rural incomes, alleviating poverty, and meeting drinking water as well as other human and industrial needs. It is now widely recognized that apart from engineering feats, good institutional arrangements are crucial for the sound management of the resource. In light of this, the development of water institutions has been taken up in India, but remains a major weakness. Existing water institutions are found to be lacking on various counts, and one of the critical deficiencies identified is the lack of adaptiveness to the significantly varying resource status, the...

Adding value to local resources specifically tailored for developing São Paulo State’s vitiviniculture
Provedor de dados: 31
Autores: Verdi,   Adriana Renata; Otani,   Malimiria Norico; Fredo,   Carlos Eduardo.
São Paulo state’s vitiviniculture ranks second in Brazil, being characterized by the production of table grapes and wines derived from American and hybrid varieties. Despite its economic, social, and environmental benefits, the state’s vitiviniculture has witnessed an increasing dependence on grapes produced in other states over the last decade. Besides adding to the cost of producing wine in São Paulo, grape imports from the state of Rio Grande do Sul compromises not only product quality, but also the process of creating an identity for the product. To give a new impetus to the production of grapes and wines in São Paulo, the State of São Paulo Research Foundation (FAPESP) developed a project called “Revitalizing São Paulo’s Vitivinicultural Chain,” a...

Addition of waste and introduction of microorganisms after 45 years of soil degradation
Provedor de dados: 124
Autores: Santos,Adriana Avelino; Agustini,José Antônio; Maltoni,Kátia Luciene; Cassiolato,Ana Maria Rodrigues.
ABSTRACT The construction of hydroelectric power plants (HPP) may result in environmental problems, such as extensive areas of exposed subsoil and conditions of extreme degradation. These areas require alternative that minimize impact and allow partial recovery of their ecosystem functions and vegetation. This study aimed to evaluate the effects of residue addition (organic/macrophytes - OR and inorganic/ash - AR), hydrogel, and inoculation of microorganisms in degraded soil, cultivated with Jatropha curcas, through fertility and microbial activity. A conserved Cerrado ("savannah") soil was the source of microorganisms - mainly mycorrhizal fungi. The experiment was conducted for 12 months (during 2010/2011) at the farm of UNESP-School of Engineering/Campus...

Additional Action Reserve: A proposed mechanism to facilitate additional voluntary and policy emission reductions efforts in emissions trading schemes
Provedor de dados: 31
Autores: Twomey,   Paul; Betz,   Regina; MacGill,   Iain; Passey,   Robert.
An additional action reserve (AAR) is proposed as a mechanism that allows government and voluntary private interests to make additional emission reductions beyond a national cap. A proportion of Australian emission units (AEUs) is set aside each year. The units can then be retired if state or local government, businesses or individuals take specific emission reduction measures that go beyond those expected from the Carbon Pollution Reduction Scheme (CPRS). AEUs allocated to the reserve that are not retired through additional activities would be made available to CPRS participants.   By providing an upper bound to such actions, the scheme would limit uncertainty about how many permits are available for emitters. The scheme would also provide a limit to the...

Addressing scope of inference for global genetic evaluation of livestock
Provedor de dados: 96
Autores: Tempelman,Robert John.
Genetic evaluations should become more accurate with the advent of whole genome selection (WGS) based on high density SNP panels. The use of WGS should then accelerate genetic gains for production traits given likely decreases in generation interval due to the greater intent to select more animals based just on their genotypes rather than phenotypes. However, past and current genetic evaluations may not generally connect well to the intended scope of inference. For example, estimating haplotype effects from the data of a single reference population does not bode well for the use of WGS in other diverse environments since the scope of inference is too narrow; conversely, WGS based on estimates, for example, derived from daughter yield deviations of dairy...

Adjustment of Wheat Production to Market Reform in Egypt
Provedor de dados: 31
Autores: Kherallah,   Mylene; Minot,   Nicholas; Gruhn,   Peter.
In response to slow growth in the agricultural sector and as part of a general shift towards a more market-oriented economy, the Government of Egypt started liberalizing the agricultural sector in 1987. Controls over wheat production and marketing were eliminated and wheat producer prices were brought closer to international levels. As a result, there has been remarkable increases in wheat crop area and yields, causing wheat production to triple from 1986 to 1998. This study analyzes the results of a survey of 800 Egyptian wheat farmers in order to address three issues that are of interest to agricultural reform policy in Egypt. First, what are the patterns in wheat production and marketing that have emerged following the economic reforms? Second, why is...

Adoption and Abandonment of Organic Farming: An Emperical Investigation of the Irish Drystock Sector
Provedor de dados: 21
Autores: Läpple, Doris.
There is a considerable literature about the adoption of organic farming. However,  possible abandonment of organic farming has received scant attention.  Thus, relatively little is known about the exit decisions of farmers. In addition,  most studies are based on a static framework where it is not possible to account  for changes in farmer decisions over time. This article attempts to fill this gap in  the literature by investigating the determinants that affect both adoption and  abandonment of organic drystock farming over time. The use of duration analysis  allows for the consideration of cross-sectional and time-varying factors over  the study period from 1981 to 2008. Using this dynamic econometric framework  revealed a significant time effect on...

Adoption and impacts of zero tillage as a resource conserving technology in the irrigated plains of South Asia
Provedor de dados: 31
Autores: Erenstein,   Olaf; Farooq,   Umar; Malik,   R.K.; Sharif,   Muhammad.
The recent stagnation of productivity growth in the irrigated areas of the Indo-Gangetic Plains of South Asia has led to a quest for resource-conserving technologies that can save water, reduce production costs and improve production. The present synthesis of two detailed country studies confirmed widespread adoption of zero tillage (ZT) wheat in the rice-wheat systems of India’s Haryana State (34.5% of surveyed households) and Pakistan’s Punjab province (19%). The combination of a significant “yield effect” and “cost-saving effect” makes adoption worthwhile and is the main driver behind the rapid spread and widespread acceptance of ZT in Haryana, India. In Punjab, Pakistan, adoption is driven by the significant ZT-induced cost savings for wheat...

In order to diversify the sources of incomes of the country, to reduce the financial risks and to improve the farmers’ revenues, the government of Benin decided to promote new agricultural sectors. One of those new sub-sectors is shea tree which is targeted in this study. Due to the painful of certain stages of shea butter processing, the semi-mechanization was initiated. The paper uses data from a stratified random sample of 198 shea butter producers to assess the adoption and impact of this semi-mechanization in North-Benin. A multinomial probit model is estimated to analyze the factors which explain the adoption of each type of technology. A counterfactual approach drawing from a modern evaluation theory is used to evaluate the impact of this...

Provedor de dados: 31
Autores: Mignouna,   D.B.; Mutabazi,   K.D.S.; Senkondo,   E.M.; Manyong,   Victor M.
Declining yields of maize as a result of Striga infestation has necessitated a new technology known as Imazapyr-resistant maize (IRM) to contain the problem. As a result, research and development initiatives with substantial participation of the private sector to transfer this new technology to farmers have been made in western Kenya. This study therefore assesses the adoption of IRM variety and efficiency levels of farmers in western Kenya. A multi-stage sampling technique was used to select a total of 600 households from Nyanza and Western provinces for this study. Tobit model and stochastic production frontier analysis were the analytical methods. Results show that age, education, maize production gap, risk, contact with extension agents, lack of seeds,...

This study reports the first case of adoption in a wild group of black and gold howler monkeys (Alouatta caraya). After the death of one adult female with a dependent infant, her daughter with a dependent infant adopted the orphan of similar age of her own infant. We recorded the activity and proximity between the adopter and both infants during two following days. The adoptive female appeared to provide equal treatment toward both infants and the orphan seemed to recognize the female as his mother. This report suggests that adult females of A. caraya can rear two infants at once.

Adoption of Conservation Agriculture Technologies by Smallholder Farmers in the Shamva District of Zimbabwe: A Tobit application
Provedor de dados: 31
Autores: Chiputwa,   Brian; Langyintuo,   Augustine S.; Wall,   Patrick.
Conventional agricultural practices such as the use of the moldboard plough are no longer sustainable due to their extensive soil degradation effects. As a panacea, several Conservation Agriculture (CA) technologies have been promoted to improve soil structure and water conservation. However, adoption of these technologies has been resisted by smallholder farmers and identifying causes of the low adoption rates to facilitate intervention strategies remains a challenge to development practitioners. Using data from 100 farmers, this paper uses a Tobit application to assess the underlying factors important in determining farmers’ adoption of zero-tillage, crop rotation and contour ridging technologies. Empirical results suggest that adoption and use intensity...

With increasing environmental concerns, increasing population, changing tastes and preferences of consumers towards healthier foods, and with more food safety requirements, agronomic practices have changed gradually to provide not only food and fiber but also public goods and other beneficial services from agriculture. Cover cropping is one type of technology increasingly being adopted by producers of multifunctional agriculture. Cover crops provide a range of benefits, both private and public. In this paper we identify factors affecting farmers’ choice to adopt cover crops. We examine the impact on nitrogen use from adopting cover crops and the resultant decrease in input costs. Using a two-stage approach that incorporates endogeneity of adoption in...

Adoption of Improved Maize and Common Bean Varieties in Mozambique
Provedor de dados: 31
Autores: Lopes,   Helder.
Household adoption of new agricultural technologies, including improved maize and bean varieties in Mozambique, is still relatively low. As a result, the average maize and common bean production remains low. This study identifies factors that are associated with households’ adoption of improved maize and bean varieties, using Trabalho de Inquérito Agrícola (TIA) 2007 data and the probit model to estimate the likelihood of household adoption of improved varieties of maize and common beans at both the national and regional levels. At the national level, the results indicate that household head’s education, access to extension services and credit are associated with the household’s adoption decision. However, association membership is negatively associated...

Provedor de dados: 17
Autores: Rennie O. Lakadong; Amal C. Kataki; Rajeshwar N. Sharan.
Background: Poly-ADP-ribosylation (PAR), a reversible post-translational modification of cellular proteins, is involved in various cellular and molecular processes including carcinogenesis (Althaus &amp;#x26; Richter, 1987; Jacobson &amp;#x26; Jacobson, 1989; Poirier &amp;#x26; Moreau, 1992; Boulikas, 1993; Sharan, 2009). ADP-ribose polymer adducts are added onto target cellular proteins by this metabolic process. We hypothesize that a decrease in the concentration of total poly-ADP-ribose adducts of peripheral blood lymphocyte (PBL) proteins strongly correlates with incidence of human cancer. &amp;#xd;&amp;#xa;Methods: A novel, sensitive and convenient immunoprobe assay of poly-ADP-ribose adducts of cellular proteins has been employed using slot blots of...

Adsorção de fósforo em frações argila na presença de ácido fúlvico
Provedor de dados: 90
Autores: Cessa,Raphael Maia Aveiro; Vitorino,Antonio Carlos Tadeu; Celi,Luisella; Novelino,José Oscar; Barberis,Elisabetta.
Os ácidos orgânicos podem ser adsorvidos aos coloides do solo, favorecendo maior disponibilidade de P às plantas. Por meio de isotermas, avaliou-se a influência de ácido fúlvico (AF) sobre a adsorção de P na fração argila de dois Latossolos Vermelhos (LVdf e LVd), caulinita natural pouco cristalizada (KGa2), goethita (Gt) e hematita (Hm) sintéticas. As isotermas de adsorção de P ajustadas pelo modelo de Langmuir na presença de AF foram adequadas somente para a região de baixa concentração de P. De maneira geral, a presença de AF incubado nas frações argila estudadas foi capaz de reduzir a adsorção de P. Na fração argila do LVdf, a adsorção de P em baixas e altas concentrações desse nutriente teve pequena influência da sequência de incubação de P com AF,...

Autores: Broggi,Fábio; Oliveira,Alexandre C. de; Freire,Fernando J.; Freire,Maria B. G. dos S.; Nascimento,Clístenes W. A. do.
The objectives of this work were to evaluate the relationship between phosphate adsorption in different mineral soil constituents of the clay fraction to determine the P recovery rate by the Mehlich-1, Mehlich-3, Bray-1 and CaCl2 0.01 mol L-1 extractants as a function of incubation time of soil as well as to compare this rate with physical and chemical soil characteristics. In five soil samples five doses of P based on the maximum phosphate adsorption capacities (MPAC) of the soil, were applied, corresponding to 0, 0.2, 0.4, 0.8 and 1.0 level. The samples were incubated for 90, 60, 30, 15 and 0.5 days. The experiment consisted of a 5 x 4 x 5 factorial (five doses, four extractants and five different periods of incubation time) in five different soils, all...

Adsorption of Cd, Cu, Ni and Zn in tropical soils under competitive and non-competitive systems
Provedor de dados: 63
Autores: Moreira,Cindy Silva; Alleoni,Luís Reynaldo Ferracciú.
The adsorption of heavy metals in soils affects their behavior in the environment and their bioavailability to plants. The knowledge of the adsorption mechanisms in competitive systems allows a more realistic evaluation of the metals' behavior in the soil than the single metal adsorption. The objectives of this study were (i) to evaluate Cd, Cu, Ni, and Zn adsorption in 14 surface samples (0-0.2 m) of representative soils of the Brazilian humid-tropical region, in competitive and non-competitive systems, and (ii) to establish metal affinity sequences for each soil, based in the maximum adsorption capacity (MAC) estimated by the Langmuir model. The Rhodic Eutrudox, the Kandiudalf Eutrudox, the Arenic Hapludalf, the Arenic Hapludult and the Typic Argiudoll...

Adubo orgânico revitaliza o solo: preparo de solo garante aproveitamento dos nutrientes pela mandioca.
Provedor de dados: 14
Autores: SILVA, J. da.
Solos profundos e que não apresentam impedimentos físicos ao crescimento radicular e com fertilidade adequada, quanto ao pH e disponibilidade de nutrientes, são os ideais para a mandioca. Os solos geralmente evitados pelos agricultores são aqueles com afloramentos rochosos, com pedras ao longo do perfil, e aqueles com alto teor de argila, pensando principalmente no momento da colheita, em que geralmente há dificuldade no arranquio e muitas perdas de raízes. portanto, os solos de textura média são os preferidos. No entanto, deve-se ter cuidado adicional no seu preparo e melhoria de sua fertilidade (correção e adubação), geralmente com baixo teor de nutrientes.

Adult carbohydrate feeding affects reproduction of Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae)
Provedor de dados: 82
Autores: Jordão,Alexandre L; Nakano,Octávio; Janeiro,Vanderly.
Reproduction of most insects depend on nutrients accumulated during the larval stage, but many lepidopteran species will also depend on nutrients obtained at the adult stage. Feeding at the adult stage allows the intake of carbohydrate and amino acid rich solutions, which may have an effect on the species reproduction and population growth. The objectives of the current study were to characterize the effects of sugar consumption by adults of the potato tuber moth, Phthorimaea operculella (Zeller), on its reproduction. To initially test the food intake by adults, a 10% honey solution or water (control), both containing a liquid dye were offered to adult insects 24h after emergence, and the presence of the dye was observed by analysis of their digestive...

The association between types of food access and rising adult obesity rates is increasingly recognized, as a complement to the effects of declining physical activity.  Previous studies have examined the effects on obesity of only a limited set of store types, such as grocery stores, fast food restaurants and big-box retailers, and they have ignored that certain behavioral factors, such as could play a role in the relationship between food access and obesity.  This analysis includes a comprehensive array of food-providing establishments, including limited- and full-service restaurants controlling for fruit-and-vegetables (F&amp;V) consumption (lagged temporally) using a panel data set for the continental U.S. states covering the period 1997-2005.

Autores: Costa,Marcelo; Mateus,Rogério Pincela; Moura,Mauricio Osvaldo; Machado,Luciana Paes de Barros.
The behavioral biology has a central role in evolutionary biology mainly because the antagonistic relations that occur in the sexual reproduction. One involves the effect of reproduction on the future life expectation. In this scenario, changes in male operational sex ratio could lead to an increase in mortality due to costs associated with excessive courtship and mating displays. Thus, this work experimentally altered the male sex ratio of Drosophila melanogaster Meigen, 1830, to determine its impact on mortality. The results indicated that mortality increases as the sex ratio changes, including modifications in the survivorship curve type and in the curve concavity, measured by entropy.

Advanced insights into magmatism and volcanism of the Mozambique Ridge and Mozambique Basin in the view of new potential field data
Provedor de dados: 5
Autores: Koenig, Matthias; Jokat, Wilfried.
P&gt;A new plate tectonic model is presented which describes the emplacement of the Mozambique Ridge off southeast Africa as the result of long lasting volcanic activity (140-122 Ma) during the initial opening between Africa and Antarctica. Thus, an oceanic origin for the Mozambique Ridge is proposed. This model is based on a new and systematic high resolution magnetic anomaly data set acquired across the Mozambique Ridge and throughout the Mozambique Basin. Data from the Mozambique Basin allow the identification of Mesozoic magnetic anomalies from M0r to M26 (124.61-155.3 Ma) with previously unmatched accuracy. Small-scale fracture zones are recognized by offsets of magnetic anomalies in the westernmost part of the basin. Additionally, a bend in the major...

Provedor de dados: 117
Autores: Polanco,Víctor; Paredes,Mario; Becerra,Viviana; Pérez,Eduardo.
Apple (Malus domestica Borkh.) is one of the most consumed fruit in the world. Genetic transformation is a key process to sustain this demand by permitting the potential enhancement of existing cultivars as well as the development of new cultivars resistant to pests, diseases, and storage problems that occur in the major production areas. This review summarizes the advances of genetic engineering applied to the development of resistant apple cultivars to fungus disease, with particular attention in the generation of apples resistant to Venturia inaequalis (Cooke) G.Winter, the main phytosanitary problem that affects apple crops in Chile.

Advances in biliary atresia: from patient care to research
Provedor de dados: 56
Autores: Santos,J.L.; Carvalho,E.; Bezerra,J.A.
Biliary atresia, the most common cause of liver transplantation in children, remains a challenge for clinicians and investigators. The development of new therapeutic options, besides the typical hepatoportoenterostomy, depends on a greater understanding of its pathogenesis and how it relates to the clinical phenotypes at diagnosis and the rate of disease progression. In this review, we present a perspective of how recent research has advanced the understanding of the disease and has improved clinical care protocols. Molecular and morphological analyses at diagnosis point to the potential contributions of polymorphism in the CFC1 and VEGF genes to the pathogenesis of the disease, and to an association between the degree of bile duct proliferation and...

Adverse Selection in Conservation Auctions: Theoretical and Experimental Results
Provedor de dados: 31
Autores: Arnold,   Michael; Duke,   Joshua M.; Messer,   Kent D.
This paper evaluates land preservation and conservation programs by examining the performance of a discriminative auction that is often used to select parcels in the U.S. The paper hypothesizes that the auction is unlikely to be cost effective because an information asymmetry introduces adverse selection. Experiments are used to examine the extent of adverse selection and compare it to a baseline where no programs exist. Then, we examine the ability of two mechanisms to correct the incentive problem. The results show that adverse selection is likely to exist in conservation auctions (achieving just 60.7% of total possible social efficiency in the experiments) and that a mechanism can sort types so as to improve cost effectiveness with respect to the...

Adverse Selection in the Environmental Stewardship Scheme: Evidence in the Higher Level Stewardship Scheme?
Provedor de dados: 31
Autores: Quillerou,   Emmanuelle; Fraser,   Rob W.; Fraser,   Iain.
The Environmental Stewardship Scheme provides payments to farmers for the provision of environmental services based on foregone agricultural income. This creates a potential incentive compatibility problem which, combined with an information asymmetry on farm land heterogeneity, could lead to adverse selection of farmers into the Scheme and therefore reduced cost-effectiveness of the Scheme. This reduced cost-effectiveness would be represented by a systematic overpayment of farmers for the land enrolled into the Scheme, compared to the opportunity cost of production.

Adversity and sex differences in social and emotional sensitivity in children; a possible mechanism for sex differences in psychiatric disorders
Provedor de dados: 17
Autores: Jonathan Hill; Helen Sharp; Lynne Murray.
Females are superior to males on a range of tasks indexing social sensitivity, the capacity to infer others&amp;#x27; mental states and respond with appropriate behaviours and emotions(1-3). There are also sex differences in psychiatric disorders in children and adolescents. Boys have higher rates of psychiatric disorders before puberty, but disorders increase markedly in girls after puberty (4). The causes of the commonest forms of disorder, antisocial behaviour problems in boys, and depression in girls, entail altered brain function caused by genetic variations and psychosocial adversities mainly arising in the family, and the interaction between the two (5;6). This may be explained by sex differences in social and emotional sensitivity provided they...

Advocatus, et non latro? Testing the Supplier-Induced-Demand Hypothesis for Italian Courts of Justice
Provedor de dados: 31
Autores: Buonanno,   Paolo; Galizzi,   Matteo M.
We explore the relationship between litigation rates and the number of lawyers, in a typical supplier-induced demand (SID) frame. Drawing on an original panel dataset for the 169 Italian courts of justice between 2000 and 2007, we first document that the number of lawyers is positively correlated with different measures of litigation rate. Then, using an instrumental variables strategy we find that a 10 percent increase of lawyers over population is associated with an increase between 1.6 to 6 percent in civil litigation rates. Thus, our empirical analysis supports the SID hypothesis for the Italian lawyers: following an increase in their relative number, lawyers may exploit their informational advantage to induce clients to access to courts even when...

Aerial surveys of bluefin tuna in the Western Mediterranean sea: retrospective, prospective, perspective
Provedor de dados: 5
Autores: Bonhommeau, Sylvain; Farrugio, Henri; Poisson, Francois; Fromentin, Jean-marc.
While the current stock status of bluefin tuna (BFT) has been considered as declining, there remain considerable data limitations for its stock assessment in the Mediterranean Sea. The collection of fishery-independent data reveals to be crucial to compensate for the lack of Mediterranean purse seine CPUE indices as well as to overcome a potential halt in the bluefin tuna fishery that would impede the monitoring of the stock and the comparison to reference points. Here we present a retrospective of aerial surveys that have been carried out since 2000. It includes the protocol as well as a retrospective of temporal and spatial distribution of detected schools. We then propose several perspectives that could improve the data collection method itself and the...

Provedor de dados: 96
Autores: Bumbieris Junior,Valter Harry; Jobim,Clóves Cabreira; Emile,Jean-Claude; Roman,Juliano; Silva,Michele Simili da.
The objective of the present study was to evaluate the aerobic stability and losses during the fermentation process of triticale silages in single crop or in mixtures with oats and/or legumes. The following crops were used for silage production: triticale (X. Triticosecale Wittimack), triticale intercropped with forage pea (Pisum arvense) and triticale intercropped with oats (Avena strigosa Schreb), forage pea and vetch (Vicia sativa). The dry matter content and its recovery did not differ among the silages. Buffer capacity was higher for tricale silage intercropped with oats, forage pea and vetch(88.67 m eq. NaOH/100 g DM) followed by triticale intercropped with forage pea (80.80 m eq. NaOH/100 g DM). Electric conductivity values were higher in the...

Affordances of distractors and compatibility effects: a study with the computational model TRoPICALS
Provedor de dados: 17
Autores: Daniele Caligiore; Anna M. Borghi; Domenico Parisi; Rob Ellis; Angelo Cangelosi; Gianluca Baldassarre.
Seeing an object activates in the brain both visual and action codes. Crucial evidence supporting this view is offered by compatibility effect experiments (Ellis et al. (2007). J Exp Psychol: Hum Percept Perform): perception of an object can facilitate or interfere with the execution of an action (e.g. grasping) even when the viewer has no intention of interacting with the object. TRoPICALS (Caligiore et al. (2010). Psychol Rev) is a computational model developed to study compatibility effects. It provides a general hypothesis about the brain mechanisms underlying compatibility effects, suggesting that the top-down bias from prefrontal cortex (PFC), and its agreement or disagreement with the affordances of objects, plays a key role in such phenomena....

AFLP analysis of Xanthomonas axonopodis and X. arboricola strains used in xanthan production studies reveal high levels of polymorphism
Provedor de dados: 58
Autores: Mayer,Laurí; Silva,Wladimir Padilha da; Moura,Andrea Bittencourt; Vendruscolo,Claire Tondo.
Amplified fragment length polymorphism (AFLP) was used to analyze the genetic diversity of 14 strains of Xanthomonas arboricola pv. pruni and seven strains of X. axonopodis pv. phaseoli, which are used in xanthan production studies. Relationships identified by the AFLP profiles were assessed for xanthan production capacity, geographical location and host plant. Strains were isolated from 10 different geographic regions in South and Southeast States in Brazil. Data were analyzed for genetic similarity using the Dice coefficient and subjected to UPGMA cluster analysis. A total of 128 AFLP fragments were generated from four primer combinations: EcoRI+C/MseI+0, EcoRI+A/MseI+0, EcoRI+G/MseI+T and EcoRI+G/MseI+A. Of these, 96.1% were polymorphic. X. axonopodis...

African hunt for investment: any chance for success?
Provedor de dados: 31
Autores: Dyakov,   Ignaty.
During recent two decades the world has witnessed a drastic increase in global FDI inflows. Gradually more and more investment has been directed to the developing countries in the attempt to diversify portfolios and use finance in the most efficient way. Not all developing regions of the world perfectly succeeded in attracting FDI. Large by labor force and territory, abundant in natural resources Sub-Saharan Africa could perform much better in this aspect. This paper once again reviews the opportunities for FDI in Africa and suggests possible ways for authorities of African states to overcome the existing situation.

African wild ungulates compete with or facilitate cattle depending on season
Provedor de dados: 17
Autores: Wilfred O. Odadi; Moses Karachi; Shaukat Abdulrazak; Truman Young.
Savanna ecosystems are vital for both economic and biodiversity values. In savannas worldwide, management decisions are based on the concept that wildlife and livestock compete for grassland resources[1-4], yet there are virtually no experimental data to support this assumption[1]. Specifically, the critical assessment of whether or not wild ungulates alter livestock performance (e.g., weight gain, reproduction or survival) has rarely been carried out, although diminished performance is an essential prerequisite for inferring competition[1]. Here we use a large-scale experiment in a semi-arid savanna in Kenya to show that wild ungulates do depress cattle performance (weight gain) during the dry season, indicating a competitive effect, but enhance cattle...

I used the 2010 Deepwater Horizon oil spill to examine how crowdsourcing is used as a new form of citizen science that provides real time assessments of health-related exposures. Assessing risks of an oil spill, or disasters more generally, is a challenge complicated by the situated nature of knowledge-generation that results in differential perceptions and responses. These processes are critical in the case of the British Petroleum spill in the Gulf Coast since the identification of risks promises to have ramifications for multiple social actors, as well as the health status and long-term resilience of communities in the area. Qualitative interviews, ethnographic observations, and video data were collected with local social movement organizations,...

The age of fish in a population is fundamental to most of the questions fishery biologists attempt to answer about that population. The aim of this study was to report the parameters of the weight-length relationship and to estimate the age and growth of Phycis phycis (Linnaeus, 1766) in Gulf of Tunis. A sample of 272 specimens of P. phycis was collected from the landings of the small-scale artisanal fisheries between September 2007 and June 2010. The total length (TL) ranged from 14 to 55.5cm and total weight (TW) from 45 to 1779g. Length-weight relationship were described by allometrically positive for the females (TW = 0.0083*TL3. 0703), males (TW= 0.0063*TL3.1471), and both sexes (TW= 0.0082*TL3. 0759).

Age and Growth of the lemon sole (Microstomus kitt) in the Celtic Sea and the North Sea
Provedor de dados: 5
Autores: Mahe, Kelig; Elleboode, Romain; Persohn, Cecile; Dufour, Jean-louis.
Age and growth of lemon sole (Microstomus kitt) were determined from 115 specimens collected in the Celtic Sea and in the North Sea in 2006 and 2007. Total length is ranged from 11 to 44 cm, while total weight varied between 12 and 1040 g. Age estimation was based on otoliths readings. The oldest male and female were estimated to be 9 years old. The length–weight relationships parameters for lemon sole in the Celtic Sea and in the North Sea were W=0.0043*TL3.2860 and W=0.0062*TL3.1505 respectively. Weight including both sexes increased with positive allometric growth. The von Bertalanffy growth equation in the North Sea was fitted on the basis of mean length-at-age data resulting in parameters values of TL∞ = 36.44 cm (S.E. = 0.484), K = 0.187 /y (S.E. =...

ABSTRACT Studies on age and growth of fish populations have direct application in fisheries and contribute for policies of conservation. Our aim was update information on the Micropogonias furnieri growth parameters based on sagittae otoliths annulis readings, and we expected that the studied population from Southeast Brazil can reach more longevity than the reported in the available literature. We examined 286 individuals between August-2010 and July-2011 from Ubatuba Bay, SP. The Total Length ranged 200-480 mm. The determined growth parameters were: Males, L∞ =523.4mm, k = 0.05×year-1, t0 = -8.78 year; Females L∞ = 573.5mm, k = 0.06 × year-1, t0 = -7.49 year.

Provedor de dados: 20
Autores: Gaamour, A.; Missaoui, M.; El Abed, A.; Deniel, Ch.
A new osseous part, the opercula bone, is used to estimate the age of 2099 round sardine Sardinella aurita, Valenciennes, 1847 captured in the Cap Bon area. The period of sampling, with a monthly rhythm, is spread out June 1994 at December 1995 and from June to September 1996. The relation between the length of fish (LF) and the ray of opercula (RT) is LF = 22,25 RT 0,994. The validation of the age estimate method is carried out directly by the monthly follow-up of average marginal lengthening and the percentage of individuals with marginal hyaline zone. This study showed that the round sardine has a double cycle of growth per year. The analysis of the key age-length shows that the females dominate in the majority of the age groups. The parameters of...

Age polyethism in Plebeia emerina (Friese) (Hymenoptera: Apidae) colonies related to propolis handling
Provedor de dados: 82
Autores: Santos,Camila G dos; Blochtein,Betina; Megiolaro,Fernanda L; Imperatriz-Fonseca,Vera L.
Stingless bees collect plant resins and make it into propolis, although they have a wider range of use for this material than do honey bees (Apis spp.). Plebeia spp. workers employ propolis mixed with wax (cerumen) for constructing and sealing nest structures, while they use viscous (sticky) propolis for defense by applying it onto their enemies. Isolated viscous propolis deposits are permanently maintained at the interior of their colonies, as also seen in other Meliponini species. Newly-emerged Plebeia emerina (Friese) workers were observed stuck to and unable to escape these viscous propolis stores. We examined the division of labor involved in propolis manipulation, by observing marked bees of known age in four colonies of P. emerina from southern...

Age structure and growth of the rough scad, Trachurus lathami (Teleostei: Carangidae), in the Southeastern Brazilian Bight
Provedor de dados: 103
Autores: Ruas,Lygia C.; Vaz-dos-Santos,André M.
ABSTRACT The rough scad, Trachurus lathami Nichols, 1920, is a small pelagic species distributed along the West Atlantic coast. It is most abundant in the Southern Brazil (28°30’-34°S) and in the Southeastern Brazilian Bight (SEBB, 22°-28°30’S). The rough scad is fished by purse seines, which main target is the Brazilian sardine, Sardinella brasiliensis (Steindachner, 1879). Age and growth are vital to understand the life cycle of a species, to fishery management and ecosystem modeling. This study aimed to assess the age and growth of T. lathami, to identify its age structure in the SEBB, and to evaluate what causes the wide differences among Trachurus species in terms of body size and growth parameters. Data available on T. lathami was attained between...

AGEING AND CONSUMPTION – THE IMPACT OF DEMOGRAPHIC CHANGE ON FOOD EXPENDITURE PATTERNS
Provedor de dados: 31
Autores: Anders,   Sven M.
Populations in most developed countries are ageing while fertility is declining. Policy makers and researchers expect this demographic shift to induce major shifts in most Western societies, economies and public policies. Moreover, changing requirements, demands and public health pressures (e.g. diabetes) of ageing populations are expected are likely to alter food expenditure patterns for various goods categories, including food products. The objective of this paper is to investigate to what extent household's food expenditure patterns shift around retirement age and what role changes in time use spend on home production play in this context. More specifically this paper reviews literature relevant to economic literature that has evolved around Modigliani...

Agenda de segurança do Equador : estudo crítico sobre as respostas do estado equatoriano frente aos desafios regionais
Provedor de dados: 122
Autores: Meller, Laura Schilling.
Este estudio aborda el tema de la seguridad en la Región Andina en la perspectiva del Ecuador.  El objetivo es analizar el cambio en la agenda de seguridad ecuatoriana durante la última década y que lo ocasionó, así como verificar la capacidad de reacción del Ecuador frente al contexto regional de seguridad.  Esta investigación permite concluir que la agenda de Ecuador prioriza en la actualidad los temas de seguridad relacionados a las amenazas provenientes de la frontera norte, siendo eso posible debido al fin de la disputa con el Perú.  Tal situación es en parte una consecuencia del impacto de la política de seguridad estadounidense en la región, en alianza con Bogotá; sin embargo, las vulnerabilidades internas del Estado Ecuatoriano son igualmente...

Ageneiosus uranophthalmus, a new species of auchenipterid catfish (Osteichthyes: Siluriformes) from river channels of the central Amazon basin, Brazil
Provedor de dados: 83
Autores: Ribeiro,Frank Raynner V; Py-Daniel,Lúcia H. Rapp.
Ageneiosus uranophthalmus is described from river channels of the central Amazon basin, Brazil. The new species is widely distributed in the Amazon and is distinguished from its congeners by the V-shape snout and eye laterally placed and dorsally oriented, more visible in dorsal view than in ventral view. Ageneiosus uranophthalmus shows a range of variation on color pattern when compared with its congeners. This and other differences are described and discussed herein.

Agentenbasierte Modellierung von Landnutzungsdynamiken und Politikoptionen
Provedor de dados: 31
Autores: Berger,   Thomas.
Agent-based modeling offers the technical opportunity to spatially integrate biophysical and socio-economic model components, thereby capturing the interactions between agricultural and environmental policy measures, land use decisions and ecological processes. Development paths in the use of resources can be calculated with the help of computer stimulations which determine the range of possible farm adjustments and policy interventions. Through coupling with global modeling systems, scenario analyses can be run to investigate the impacts of global change on land and water resources at regional and local level. This article gives an overview of agent-based modeling applied to the study of land use dynamics and policy options. It outlines an agricultural...

Agglomeration Economies in Ukrainian Dairy Sector: a Marked Point Process Approach
Provedor de dados: 31
Autores: Brümmer,   Bernhard; von Cramon-Taubadel,   Stephan; Nivievskyi,   Oleg; Schlather,   Martin.
Even after more than 15 years of transition from plan to market, agriculture in Ukraine still faces many challenges in terms of its structure. The evidence in the literature points to significant heterogeneity of technical efficiency and productivity scores in Ukraine. Moreover, both the recently approved WTO accession, and the ongoing negotiations on a free trade agreement with the EU will require further improvements in productivity and competitiveness at the farm level. Using farm-level data for 2004-2005, we study the presence and possible causes of agglomeration economies in Ukrainian dairy sector. One of the most important results is that there are agglomeration effects in the sector. The performance of dairy farms is influenced by the performance of...

Aggregate and Farm-level Productivity Growth in Tobacco: Before and After the Quota Buyout
Provedor de dados: 31
Autores: Kirwan,   Barrett E.; White,   T. Kirk; Uchida,   Shinsuke.
We examine the distortionary effects of agricultural policy on farm productivity by examining the response of U.S. tobacco farmers' productivity to the quota buyout of 2004. We isolate the impact of distortionary policy, i.e., the tobacco quota, by decomposing aggregate productivity growth into the contribution of farm-level productivity growth and the contribution of reallocation of resources among tobacco growers. Reallocation of resources includes entry into and exit from tobacco farming, as well as growth or decline of the resources allocated to existing tobacco farms. We find that aggregate productivity of Kentucky tobacco farms grew 37% between 2002 and 2007.  Reallocation of resources among continuing tobacco farms contributed 22 percentage points...

Aggregate eco-efficiency indices for New Zealand – a Principal Components Analysis
Provedor de dados: 31
Autores: Jollands,   Nigel; Lermit,   Jonathan; Patterson,   Murray.
Eco-efficiency has emerged as a management response to waste issues associated with current production processes. Despite the popularity of the term in both business and government circles, limited attention has been paid to measuring and reporting eco-efficiency to government policy makers. Aggregate measures of eco-efficiency are needed, to complement existing measures and to help highlight important patterns in eco-efficiency data. This paper aims to develop aggregate measures of eco-efficiency for use by policy makers. Specifically, this paper provides a unique analysis by applying principal components analysis (PCA) to eco-efficiency indicators in New Zealand. This study reveals that New Zealand's overall eco-efficiency improved for two out of the...

Aggregate Milk Supply Response to the Milk Income Loss Contract Program
Provedor de dados: 31
Autores: Bryant,   Henry L.; Outlaw,   Joe L.; Anderson,   David P.
This research tests for changes in aggregate milk production due to the operation of the Milk Income Loss Contract (MILC) program since 2002. Aggregate production is decomposed into the size of the dairy herd and milk production per cow. We find no statistically significant response in either variable. This finding implies that the simultaneous operation of income and price support programs in the United States has not, thus far, proven self-defeating.

Aggregation of subtropical soil under liming: a study using laser diffraction
Provedor de dados: 90
Autores: Bortoluzzi,Edson Campanhola; Poleto,Cristiano; Baginski,Álvaro José; Silva,Vanderlei Rodrigues da.
Laser diffraction (LD) provides detailed analysis of particle size distribution. Its application to testing the stability of soil aggregates can assist studies on the aggregation of soils with contrasting electrochemical properties. The objectives of the present work were: (a) to propose a protocol for using LD to study soil aggregation, (b) to study the aggregation of an Acrisol under the influence of different doses and forms of lime. Samples were collected in 2005 from a Brazilian Acrisol that in 1994 had received 0.0; 2.0; 8.5 and 17.0 Mg ha-1 of lime, left on the soil surface or incorporated. Aggregates from 4.76 to 8.00 mm diameters were studied using the traditional method proposed by Kemper &amp;amp; Chepil (1965), with wet sieving, while...

Aggression and dominance in cichlids in resident-intruder tests: the role of environmental enrichment
Provedor de dados: 83
Autores: Nijman,Vincent; Heuts,Boudewijn A.
When establishing dominance residents have a greater likelihood to dominate intruders than vice versa, partially because the resident has more to loose that the intruder has to win. This is known as the prior residency effect. In environmentally rich environments this effect should be stronger than in poor environments. Recently Kadry &amp;amp; Barreto (2010, Neotrop Ichthyol 8: 329-332) tested this in the pearl cichlid Geophagus brasiliensis (17 test pairs) and reported that environmental enrichment led to a reduction of aggression. We here present data on four other cichlids (332 test pairs) showing a stronger prior residency effect in enriched conditions, and, for two species, an increase in aggression. We discuss possible reasons for the differences...

Autores: Depieri,Rogério A; Siqueira,Fábio; Panizzi,Antônio R.
Studies were conducted to test the effect of age and food sources on wear of the mandibular teeth of the phytophagous pentatomid, Euschistus heros (F.). The total length (µm) of the area bearing the mandibular teeth, the length of the 1st tooth, and the height of the 2nd tooth for teneral (&lt; 1 day-old) adults were significantly greater than that of adults fed on natural [green bean, Phaseolus vulgaris pods, raw shelled peanuts, Arachis hypogaea, and mature soybean, Glycine max seeds] for 30 or 60 days. Adults fed on artificial dry diet showed, in general, similar results to those of teneral adults.

A SAPARD-ban, az AVOP-ban és az NVT-ben rendelkezésre álló források a magyar agrárium és a vidéki gazdaság szerkezet-átalakításának, modernizálásá-nak megkezdését szolgálták, a szükséges változások megvalósításához viszont szerények voltak. A három program tapasztalatai azt mutatják, hogy a fejlesztési források felhasználásával kapcsolatos korábbi kételyek nem igazolódtak, a be-adott pályázatok, támogatási kérelmek forrásigénye esetenként jelentősen meg-haladta az előirányzott pénzügyi keretet. A fő célkitűzések, prioritások jórészt teljesültek, de néhány intézkedés megvalósulásában módosítást igénylő arányta-lanságok is jelentkeztek.

Agrárcenzusok szerepe az agrárinformációs rendszerben (1895-2010)
Provedor de dados: 31
Autores: Laczka,   Eva.
A rendszeres mezőgazdasági adatgyűjtések közel kétszáz éves múltra tekintenek vissza. Az 1828-tól végrehajtott felmérések a földhasználatra, növénytermelésre és az állattartásra terjedtek ki, az első „földhasználati regisztert” – az ideiglenes föld¬katasztert – 1853-ban állították fel. A szőlőterületekre, borászatra vonatkozó első statisztikát Magyarország – nemzetközi felkérésre – 1873-ban dolgozta ki, illetve hajtotta végre. A 19. század végére már Európa-szerte egyre nagyobb igény merült fel a mezőgazdasági tevékenység, a mezőgazdasági termelés részletesebb megismerésére. Az első magyar – általános – mezőgazdasági cenzus rendszerét Keleti Károly, az önálló magyar statisztikai hivatal első elnöke személyes vezetésével dolgozták ki. A nagy volumenű munka...

Agrárgazdaság és az „erős” forint

Autores: Gazdag,   Laszlo.
A Jegybank feladata a pénzstabilitás megteremtése és fenntartása, míg a többi cél (növekedés, foglalkoztatottság, egyensúly stb.) megvalósítása a gazdaságpolitikai eszköztár és intézményrendszer egyéb területeire tartozik. A pénzstabilitás primátusa ma már elfogadott a nyugati közgazdasági gondolkodásban. A valutaleértékelés kétélű fegyver, csupán az elavult exportszerkezetet konzerválja, a hatékonysági korlátok puhítása révén. A magyar gazdaság importfüggősége technikai jellegű, ezért a leértékelés csupán inflációs nyomást eredményez. Az agrárszektor részére a forint gyengülése sokkal több negatívummal járhatna, mint pozitívummal. Emelkedne az import eszközök ára, a felpörgő infláció révén szűkülne a belső piac.  ---------------------  Establishment and...

Process of transition movements in Republic of Sebia is in progress. Transition movements have not bypassed agrarian sector. Market agriculture should gain significance along this process. On this occasion we would like to emphasis two elements which affect development of Market Agriculture. Those are regionalization and specialization of agriculture. In study about agrarian regions in conditions of transition two charts are given, that pinpoint the essence of natural foundation and market opportunities in transition circumstances. Study of agro-identities starts with introspection of each reagion in respect of its natural values: plain (Vojvodina), hilly ( Sumadija), mountain-hilly (Pester). Therefore, plain region is specialized for production of stable...

Agrár-innovációs központok a kertészetben

Autores: Kovacs,   Terez.
A bemutatásra kerülő három településen a mezőgazdaság piacgazdaságra való áttérése eltérő alapokról indult, ezért különböző, de ugyanakkor eredményes agrár-innovációs utat járt be. Soltvadkertre leginkább az jellemző, hogy az eredményeket egyéni stratégiák mentén érték el, főleg azért, mert ők a vállalkozásaikat nem a rendszerváltáskor, hanem már korábban elkezdték. Mind Kisvejke, mind Mórahalom esetében egy-két külső személy kezdeményezte a fejlesztést, és amikor a bizalom és az együttműködés beindult, akkor erősödtek meg a helyi kezdeményezések. Nagyon fontos, hogy az a kívülálló, aki fejleszteni szándékozik, az ne csak hozzáértő, hanem önzetlen, a helyiek számára rokonszenves és megbízható személy legyen.

Agrárkérdések, alapkérdések, a termőföld
Provedor de dados: 31
Autores: Alvincz,   Jozsef.
A termőföld kérdése a „rendszerváltástól” kezdődően új megvilágításba került. Az azt megelőző évtizedekben hazánkban uralkodó marxi munkaérték-elmélet alapján a termőföldnek, mint a mezőgazdaság legfőbb termelési tényezőjének – mivel az nem a munka eredményeként keletkezett – hivatalosan nem volt értéke. Nem létezett valójában földpiac sem. A magántulajdon körében hagyott kis parcellák esetenkénti adásvétele még csak jelzőértékként sem volt értelmezhető a föld árára vonatkozóan.  Az elmúlt két évtized agrárpolitikai koncepciótlansága, és ebből eredően a birtokpolitika, valamint a mezőgazdasági üzemszabályozás elmaradása következtében a hazai földtulajdon-, valamint a birtokviszonyok a kárpótlási folyamat eredményét, illetve annak tovább torzult...

The Theory of Fiscal Federalism offers a normative framework to evaluate the existing allocation of competences. To derive an actual relevant scope for reforms supporting an efficient Agri-environmental Policy the general theoretical criteria have to be specified. Thus, the parameters defining theoretically the optimal degree of centralisation will be applied to sectoral characteristics. Additional agri-environmental sub-competencies will be differentiated to identify deficits regarding the Principle of Equivalence. Based on this existing infringements with respect to agri-environmental measures are noticeable what requires a changed allocation of competences.

Las condiciones para el ejercicio de la libertad expresi??n en M??xico se han transformado junto con los cambios sociales y pol??ticos que se han dado en el pa??s desde el a??o 2000. Durante a??os, el sistema pol??tico mexicano controlado por  el Partido Revolucionario Institucional (PRI)dio origen y control al ejercicio de este derecho. Es en el marco de la alternancia en el poder ejecutivo, con la llegada del Partido de Acci??n Nacional (PAN), que se generan nuevas condiciones para el debate y el ejercicio de la libertad de expresi??n.

agri benchmark: Benchmarking Beef Farming Systems Worldwide
Provedor de dados: 31
Autores: Deblitz,   Claus.
The agri benchmark Beef Network is a unique association of economists, scientists, farmers and advisors, as well as scientific and agribusiness partners from more than 30 organisations across 23 countries. The Network benchmarks 'typical' beef finishing and cow-calf farms from participating countries, which are generated from panel meetings of farmers and advisors and collated using a standard operating procedure. Once data are entered and processed using a series of Excel spreadsheet tools, it is broken down to the enterprise and animal level for performing unit cost analyses. The complexity of the data recorded enables detailed analyses and international comparisons on farm demographics (land size, stocking numbers, daily weight gain, prices), cost...

Agribusiness Firm Reactions to Regulations: The Case of Investments in Traceability Systems
Provedor de dados: 31
Autores: Heyder,   Matthias; Hollmann-Hespos,   Thorsten; Theuvsen,   Ludwig.
Markets for agricultural and food products are characterized by high information asymmetries since producers, processors and retailers are in most cases much better informed about the quality of their products than consumers (Henson/Traill 1993). Often consumers are only at (prohibitively) high costs or not at all able to control important quality criterions such as food safety, nutritional value or region of origin. Such credence attributes can result in market failure due to a lack of credible information in the market (Akerlof 1970). As a result, attempts to protect consumers against food hazards, product adulteration and deception have gained much relevance in food supply chains (Deimel et al. 2008). Besides the more or less voluntary private...

Autores: Heyder,   Matthias; Hollmann-Hespos,   Thorsten; Theuvsen,   Ludwig.
The regulatory framework of food production has changed a lot in recent years. As a result, traceability of food products as become mandatory in the European Union, nonetheless leaving room for more advanced solutions. This study answers the question what exactly determines firms’ investments in traceability systems by first developing a theoretical framework—the so‐called Tracking and Tracing Systems Investment Model—and then analyzing empirical data from the German food industry that provide in‐depth insights into companies’ investment behaviour. Altogether, 234 companies representing more than fifteen different sub‐sectors of the food‐processing industry participated in an online survey. The results show that German food firms can be divided into four...

Agribusiness participation in the economic structure of a Brazilian region: analysis of GDP and indirect taxes
Provedor de dados: 123
Autores: Kureski,Ricardo; Moreira,Vilmar Rodrigues; Veiga,Claudimar Pereira da.
Abstract: Agribusiness, including all its dimensions, is the largest economic sector in Brazil and plays a fundamental role in the development of the country's economy. About one-fourth of the Brazilian Gross Domestic Product (GDP) is composed of agribusiness. The objective of this article is to evaluate the participation of agribusiness in the economy of an important region of Brazil from 2010 to 2015. The evaluation was carried out through the decomposition of GDP, with an analysis of aggregate inputs, agro-livestock products, industrialization, and services. This article presents three main contributions to the understanding and composition of agribusiness GDP. The novelty of this article lies in the fact that it is the first work in the literature to...

Agricultura comercial y resistencia territorial : análisis de las relaciones campo-ciudad en la Provincia del Azuay (Dossier)
Provedor de dados: 122
Autores: Rebai, Nasser.
En la provincia del Azuay, la promoción de la agroecología aparece como el símbolo del  renacimiento de la agricultura familiar en el contexto migratorio regional. Entre los cambios en el uso del suelo y el mejoramiento de la economía campesina, asistimos a una mutación profunda de la ruralidad azuaya.  Sin embargo, en vez de un verdadero modelo de desarrollo territorial rural, mejor vale hablar de resistencia territorial porque las redes comerciales regionales funcionan con debilidades y no permiten la integración de una mayoría de campesinos. A pesar de una experiencia alentadora, falta todavía una visión ambiciosa que permita una vinculación más estrecha entre lo rural y lo urbano y una inserción facilitada de los campesinos más pobres.

Agricultura de precisão: possibilidades de manejo da adubação nitrogenada para o milho no Cerrado.
Provedor de dados: 14
Autores: HURTADO, S. M. C.; RESENDE, A. V. de; SILVA, C. A.; CORAZZA, E. J.; SHIRATSUCHI, L. S.
Altas produtividades de milho são dependentes da interação de fatores como clima, solo e manejo. O manejo da adubação nitrogenada é um dos principais condicionantes da produtividade, pela complexa dinâmica do nitrogênio (N) nos sistemas agrícolas. É com base nessa dinâmica que se busca estimar o potencial de suprimento de N pelo solo e o seu aproveitamento pela cultura, o que possibilita definir as recomendações de adubação. Contudo, a maioria das variáveis que influencia a necessidade de N na adubação pode mudar no espaço e no tempo, como é o caso das características edafoclimáticas que interferem no potencial de suprimento do nutriente pelo solo. Assim, para se refinar o manejo da adubação nitrogenada, é preciso considerar a sua variabilidade espacial e...

O manejo da variabilidade do solo, com o advento da agricultura de precisão, passou a ser difundido nas áreas agrícolas, sendo que a alteração de alguns atributos químicos ou físicos do solo, principalmente em áreas sobre sistemas de irrigação, pode acarretar em perdas de produtividade e nutrientes. Nesse contexto o presente trabalho teve como objetivo avaliar espacialmente as características físico-químicas do solo sobre pivô central e suas relações com a produtividade da cultura do milho. O trabalho foi realizado em setembro de 2010 na cidade de Inhacorá-RS. Foram coletadas 56 amostras de solo na profundidade de 0-0,10 m e de 0,10-0,20 m em um gride amostral de 1 hectare, essas foram submetidas a análises químicas e físicas, cada ponto amostral recebeu...

Agricultura e sustentabilidade
Provedor de dados: 25
Autores: Ricci, Écio A.; Rezende Filho, Cyro de B.; Fortes Neto, Paulo; Batista, Getulio T.
A agricultura como atividade econômica tem início na Pré-história. Essencial para a sedentarização da humanidade se desenvolveu para suprir as necessidades de alimentos e fibras que eram coletados na natureza. No período da Expansão Colonial européia, a atividade tornou-se empresarial na forma de plantation. A partir daí, aliado às formas primitivas de práticas agrícolas a atividade passa a ter caráter predatório. Considerando esse fato, vários autores destacados neste artigo, discutem a agricultura praticada de forma sustentável. Por outro lado, a Agricultura Familiar tem sido estudada por Veiga (1996), Gomes (2004), Pereira (2009), Caetano (2010) e Vargas (2010). Similarmente, a Agricultura Comercial foi analisada por Assad e Almeida (2004), Santos...

The agrarian conditions and the low relative levels of the socioeconomic indicators cause the area of the “High Jequitinhonha Valley”, in the northeast of the State of Minas Gerais, to be considered one of the most complex areas of Brazil. For this reason several governanmental administrations have recommended rural development programs. Most of these efforts, however, have not produced adequate results. This article analyzes the relationships between public programs and family farming, making a survey of the methods and results of the last three decades. It concludes that there is a need to incorporate the specificities of history, environment and culture into the rural programs. It is suggested that the programs take into consideration the experience...

Agricultural and Food Security Policy Analysis in Central America: Assessing Local Institutional Capacity, Data Availability, and Outcomes
Provedor de dados: 31
Autores: Tschirley,   David L.; Flores,   Luis; Mather,   David.
Performance of the agricultural sector in developing countries is fundamental to ensuring robust and equitable economic growth and broad-based food security. Yet donor support to agricultural development in developing countries has declined continuously for 30 years. This same period saw dramatic deterioration in developing countries’ institutional capacity to provide services to their agricultural sectors. These trends may now be changing, due in part to the global food price crisis of 2007 and 2008 and concerns that it unleashed about the world’s ability to feed its poorest inhabitants. This paper reports on the results of a two week trip to Guatemala and Nicaragua made by Michigan State University’s Food Security Group. The purpose of the trip was to...

Agricultural and Food Security Policy Analysis in Central America: Assessing Local Institutional Capacity, Data Availability, and Outcomes
Provedor de dados: 31
Autores: Tschirley,   David L.; Flores,   Luis; Mather,   David.
Performance of the agricultural sector in developing countries is fundamental to ensuring robust and equitable economic growth and broad-based food security. Yet donor support to agricultural development in developing countries has declined continuously for 30 years. This same period saw dramatic deterioration in developing countries’ institutional capacity to provide services to their agricultural sectors. These trends may now be changing, due in part to the global food price crisis of 2007 and 2008 and concerns that it unleashed about the world’s ability to feed its poorest inhabitants. This paper reports on the results of a two week trip to Guatemala and Nicaragua made by Michigan State University’s Food Security Group. The purpose of the trip was to...

AGRICULTURAL AND FOOD TRADE IN CENTRAL AND EASTERN EUROPE: THE CASE OF SLOVENIAN INTRA-INDUSTRY TRADE
Provedor de dados: 31
Autores: Bojnec,   Stefan; Hartmann,   Monika.
One of the striking features in Central and Eastern European (CEE) countries is the deterioration of their agricultural and food trade balance during transition to a market economy as imports increased faster than exports or exports even declined. This paper investigates the Slovenian agricultural and food trade in more detail focusing on changes in the geographical distribution of trade and the nature of trade specialization on the basis of the Grubel-Lloyd Intra-Industry Trade index and Marginal Intra-Industry Trade Indices. The results indicate that Slovenian agricultural and food trade largely remains of the inter-industry type with specialisation of exports towards the former Yugoslav markets and imports from the European Union. The proportion of...

Agricultural and Rural Cooperative Viability: A Management Strategy Based on Cooperative Principles and Values
Provedor de dados: 31
Autores: Novkovic,   Sonja; Power,   Natasha.
We examine some characteristics of agricultural and rural cooperatives and their management challenges, in order to illustrate possible applications of Jim Collin’s management concept, catalytic mechanisms, in the cooperative context. Agricultural cooperatives are experiencing complex governance issues, particularly in light of increased heterogeneity of member interests, and increased market and regulatory pressures. Member commitment is often recognized to be a necessary ingredient in the cooperative success, and while primary agricultural cooperatives are built on that commitment, new generation cooperatives need not be. In this article we argue that some of the governance issues may be alleviated by the application of creating catalytic mechanisms, a...

Agricultural Arbitrage, Adjustment Costs, and the Intensive Margin
Provedor de dados: 31
Autores: Tack,   Jesse B.; LaFrance,   Jeffrey T.
Farmland and capital are an important and rapidly expanding component of the agricultural economy, and empirical evidence suggests that these assets are quasi-fixed in that adjustment costs are incurred when holdings are altered. Increased interest in the rate of return for investing in farmland suggests that an important consideration is the effect of adjustment costs on this return. A novel theoretical model is developed that ties together contributions from the farmland pricing and adjustment cost literatures, and the first order conditions for a utility maximizing decision maker are rearranged into intertemporal arbitrage equations that are similar in spirit to traditional finance models. The common assumptions that land and capital are quasi-fixed...

Autores: Larson,   Ronald B.
The required courses for agribusiness degrees at forty-three school were divided into six categories. Large ranges in the percentage of required credits by category were found. Comparisons with other curricula surveys showed that some changes occurred during the last ten to twelve years. Emphasis on business skills has increased while course work in technical agriculture has decreased. By considering customer needs and competitor innovations, departments can attempt to add more value to their educational products.

Agricultural Contracting Update, 2005
Provedor de dados: 31
Autores: MacDonald,   James M.; Korb,   Penelope J.
More than half of all transactions for U.S. agricultural products are still conducted through spot market exchanges, in which commodities are bought and sold in open market transactions for immediate delivery. But a growing share of U.S. farm production is produced and sold under agricultural contracts. Such contracts between farmers and their buyers are reached prior to harvest (or before the completion stage for livestock) and govern the terms under which products are transferred from the farm. The shift of production to contracting coincides with shifts of production to larger farms. Contracts are far more likely to be used on large farms than on small ones. Marketing and production contracts covered 41 percent of the value of U.S. agricultural...

Agricultural Contracts and Alternative Marketing Options: A Matching Analysis
Provedor de dados: 31
Autores: Katchova,   Ani L.
The increasing use of agricultural contracts and processor concentration raises concerns that processors may offer lower contract prices in absence of local competition. This study examines the price competitiveness of marketing and production contracts depending on the availability of alternative marketing options. A propensity score matching method is used to compare prices using contract data from a farm-level national survey. The results show that the absence of other contractors or spot markets in producers’ areas does not lead to statistically significant price differences in agricultural contracts for most commodities, providing evidence that most agricultural processors do not exercise market power by reducing prices when other local buyers are not...

Agricultural Cooperative Organizations in Greece Throughout the 20th Century: A Critical Overview
Provedor de dados: 31
Autores: Patronis,   Vassilis; Mavreas,  Konstantinos.
The first centenary (1900-2000) of the establishment of agricultural cooperatives in the Greek countryside is an appropriate occasion for offering a critical retrospective of their operations during the 20th century. Initially, the causes of their delayed appearance and establishment in Greece are investigated. Subsequently, the large extension of agricultural credit, as well as the constantly increasing involvement of the government and banks in their internal affairs are described and analyzed. This analysis also focuses on the particular interwar conditions that favored the protectionism of the agricultural economy and the “State’s supervision” of cooperatives, an essential element of agrarian policy, even during the first post-war period. Finally, we...

Agricultural Cooperatives and Dilemmas of Survival
Provedor de dados: 31
Autores: Gray,   Thomas W.; Heffernan,   William D.; Hendrickson,   Mary K.
The context of agricultural cooperatives is undergoing major change with the development of various food and information monitoring technologies. Large multi-nationals have moved to take advantage of these developments with the construction of agri-food chains. These chains are being facilitated via various mergers, acquisitions, and alliances, with the power, and deepening power of such deep-pocket organizations as Cargill, ADM, and ConAgra. Cooperatives have been integrated into these chains for their core competencies, generally for their supply functions, and capacity to handle primary commodities. These direct links to the farmers serve as markets for biotechnology innovations, and as a source of raw material for later processing. Agricultural...

Agricultural Cooperatives in Japan: An Institutional Approach
Provedor de dados: 31
Autores: Kurimoto,   Akira.
How can we explain the reason why cooperatives have evolved so differently? This article argues that the institutional framework gives a decisive influence in organizational evolution and the historic path has been taken by interaction between institutions and organizations. The Japanese agricultural cooperatives are analyzed from institutional perspectives. They were created at the end of the 19th century under overwhelming European influence but evolved as a quite different model under the strong impacts of industrial policies and institutions. They developed as multi-purpose cooperatives bearing triple natures as state agency, pressure group and cooperative per se. The new economy is shifting public policy from protectionist to procompetition and the...

At present, agricultural cooperatives, like all cooperatives, are faced with many challenges. They are questioned about their organizational and management framework, their relations with local communities and with the market. In Italy, there is an ongoing debate relating to how cooperatives at large should or are supposed to evolve in a context in which the market pressure seems to overcome the traditional characteristics of the cooperative movement (mutuality, solidarity, the "one head one vote" principle, and so on). How to adequately balance the innovation thrust and the cooperative principles? How can agricultural cooperatives develop in the face of the 'ever overwhelming market forces?

Agricultural costs for reducing nitrogen surpluses in the Weser river basin
Provedor de dados: 31
Autores: Heidecke,   Claudia; Kreins,   Peter.
Agriculture is to a large part responsible for nitrate leaching into groundwater and rivers in Germany, especially in highly intensive agricultural regions. To evaluate the link between nitrogen surpluses from agriculture and nutrient leaching into ground- and surface waters, a model network to analyse current and future nitrogen surplus developments and water quality is set up by connecting hydrological and hydrogeological models with the German agricultural sector model RAUMIS. A set of different environmental measures and their costs is selected to fulfil surface and groundwater targets of the European water framework directive (WFD) for the case of the Weser River basin. Results show that with additional agri-environmental measures covering around 1...

Agricultural Development in Traditional Asian Economies: Observations Prompted by a Livestock Study in Vietnam
Provedor de dados: 31
Autores: Tisdell,   Clement A.
China began its economic reforms in 1979 and Vietnam followed in 1986. Since then both countries have experienced rapid economic growth, falling poverty rates and significant rises in per capita income. At the same time, substantial restructuring of their economies has occurred, a feature of which has been a decline in the relative contribution of agriculture to total employment and output. These changes are outlined. Significant changes have also occurred in the agricultural sectors of China and Vietnam and these are reviewed. In both countries, the livestock sector has grown in relative importance. Households are the main contributors to agricultural production but their individual holdings of land are small and households keeping livestock mostly only...

Agricultural Distortions in Sub-Saharan Africa: Trade and Welfare Indicators, 1961 to 2004
Provedor de dados: 31
Autores: Croser,   Johanna L.; Anderson,   Kym.
For decades, agricultural price and trade policies in Sub-Saharan Africa hampered farmers’ contributions to economic growth and poverty reduction. While there has been much policy reform over the past two decades, the injections of agricultural development funding, together with on-going regional and global trade negotiations, have brought distortionary policies under the spotlight once again. A key question asked of those policies is: how much are they still reducing national economic welfare and trade? Economy-wide models are able to address that question, but they are not available for many poor countries. Even where they are, typically they apply to just one particular previous year and so are unable to provide trends in effects over time. This paper...

AGRICULTURAL DIVERSIFICATION IN INDIA AND ROLE OF URBANIZATION
Provedor de dados: 31
Autores: Rao,   P. Parthasarathy; Birthal,   Pratap Singh; Joshi,   P.K.; Kar,   D.
Indian agriculture is diversifying during the last two decades towards High-Value Commodities (HVCs) i.e., fruits, vegetables, milk, meat, and fish products. The pace has been accelerated during the decade of 1990s. HVCs account for a large share in the total value of agricultural production. Supply and demand side factors coupled with infrastructural development and innovative institutions drive these changes. In this paper, the focus is on diversification towards HVCs in the context of urbanization. Group of urban districts (districts with &gt;1.5 million urban population) have a higher share of HVCs compared to the urban-surrounded (near urban districts) and other districts (districts in the hinterland). Among the HVCs, vegetables and meat products have...

Over fifteen years have elapsed since the transition from the centrally planned economic system started in the early 1990’s. During this time agricultural and rural areas of Central and Eastern Europe have undergone profound structural changes with wide variations in the degree of transformation and in the rate of success in creating a competitive market and private ownership based food and agricultural system. By becoming member of the European Union the "transition" in its traditional interpretation has been concluded in ten of the Central East European countries. The transition to market based agriculture, however, is far from completion in Southern and Eastern Europe and especially in the CIS countries. International Association of Agricultural...

Despite of the important role international migration fills  in the United States’ labor-intensive agricultural sector, few studies have addressed the individual characteristics and circumstances surrounding entry and exit by farm laborers. With increasing public attention on international migrant labor, policymakers have a need to understand the labor market patterns of these workers if they are to formulate appropriate immigration reforms, including temporary worker programs geared towards agriculture.  In this analysis, we model the likelihood of entering agricultural employment by migrants to the United States.  Using data from the Mexican Migration Project we find that migrants with higher levels of education and a greater command of English are less...

Provedor de dados: 31
Autores: Saunders,   Caroline M.; Kaye-Blake,   William; Campbell,   Rachel; Benge,   J.
Agri-environmental indicators (AEIs) developed by the OECD have been used to assess the environmental performance of the agricultural sector in developed countries. The Agricultural Research Group on Sustainability (ARGOS) in New Zealand has investigated using these AEIs to assess the performance of individual kiwifruit orchards. ARGOS is following panels of orchards to investigate the impacts of organic and conventional management systems on economic, sociological, and environmental dimensions of farming. The environmental monitoring of these orchards has provided data for calculating AEIs. The paper discusses the performance of ARGOS orchards, the impact of management systems, and the implications for future research.

The study examined the agricultural financing policies of the government of Nigeria and effects on rural development .The study found that though the government has made serious efforts at making good agricultural policies through schemes, programmes and institutions, it has not been able to back them up with adequate budgetary allocation and financing coupled with corruption in the execution of the policies. It is recommended that for the government agricultural financing policies to achieve its target of rural development, Nigeria will need an adequate level of strategically targeted investment in agriculture, upgrade rural infrastructure, boost productivity, and increase competitiveness of the farm output, in addition to fighting corruption.

Agricultural growth and agrarian structure in the Brazilian Cerrado: the role of land prices, natural resources and technology
Provedor de dados: 31
Autores: Rezende,   Gervasio Castro de.
This paper argues that the rapid agricultural expansion of the cerrado regions in Brazil is due to the low price of land in these regions, as compared with the other agricultural regions of Brazil and abroad. This low price of land is, in turn, attributed not only to the greater distance of these regions from the main markets, but also to the limitations of natural resources (the extremely harsh drought period, which limits agricultural activities to grains and livestock) and, above all, to technological innovations that “produced” an abundance of land of good quality. In order to show more clearly how this process has taken place, the paper develops a model of the land market that allows for “production of land,” and derives the implications of such a...

We link recent production trends to household incomes and caloric availability using a dynamic computable general equilibrium and micro-level poverty and nutrition modules. Results indicate that the structure of economic growth—not the level—is currently constraining the rate of poverty reduction in Tanzania. Agricultural growth has been driven by larger-scale farmers that are less likely to be poor. Growth has further been concentrated in crops grown in only a few regions of the country. Slow expansion of food crops and livestock also explains the weak relationship between...

Autores: Alexander,   Corinne E.; Wilson,   Christine A.; Foley,   Daniel H.
For agribusiness managers and salespeople, understanding customers and their preferences and behaviors is crucial to success. This study uses cluster analysis to identify five distinct buyer segments for expendable input purchases for U.S. crop and livestock commercial producers. A multinomial logit model is used to predict segment membership based on demographic, behavioral, and business management factors. Results provide important information for agricultural input suppliers.

Agricultural Insurances Based on Meteorological Indices: Realizations, Methods and Research Agenda
Provedor de dados: 31
Autores: Leblois,   Antoine; Quirion,   Philippe.
In many low-income countries, agriculture is mostly rain-fed and yields highly depend on climatic factors. Furthermore, farmers have little access to traditional crop insurance, which suffers from high information asymmetry and transaction costs. Insurances based on meteorological indices could fill this gap since they do not face such drawbacks. However their implementation has been slow so far.  In this article, we first describe the most advanced projects that have taken place in developing countries using these types of crop insurances. We then describe the methodology that has been used to design such projects, in order to choose the meteorological index, the indemnity schedule and the insurance premium. We finally draw an agenda for research in...

Agricultural Land Elasticities in the United States and Brazil
Provedor de dados: 31
Autores: Barr,   Kanlaya J.; Babcock,   Bruce A.; Carriquiry,   Miguel A.; Nassar,   Andre Meloni; Harfuch,   Leila.
The elasticity of aggregate supply is one key to understanding the degree to which policy-induced increases in demand for biofuel feedstocks or agricultural CO2 offsets will result in higher prices or expanded supply. In this paper we report land supply elasticities for the United States and Brazil estimated directly from the observed changes in cropland and estimated changes in expected returns. The resulting aggregate implied land-use elasticities with respect to price are quite inelastic in the United States and more elastic in Brazil (0.007-0.029 and 0.382-0.895, respectively). However, with pasture land included in Brazil, implied elasticities become much less inelastic (0.007-0.245).

Agricultural land management strategies to reduce phosphorus loads in the Gippsland Lakes, Australia
Provedor de dados: 31
Autores: Roberts,   Anna M.; Pannell,   David J.; Doole,   Graeme J.; Vigiak,   Olga.
A target to reduce phosphorus flows into the Gippsland Lakes in south-eastern Australia by 40 per cent to improve water quality has previously been established by stakeholders. An integrated analysis at the catchment scale is undertaken to assess the agricultural land management changes required to achieve this target, and to evaluate the cost-effectiveness of these changes. It appears technically feasible to achieve a 40 per cent reduction in P load entering the lakes, but the least-costly way of doing so would require around A$1 billion over 20 years, a dramatic increase in the current levels of funding provided for management. On the other hand, a 20 per cent P reduction could be achieved at much lower cost: around $80 million over 20 years and...

Agricultural Land Market Transactions in Chhattisgarh : A Case Study
Provedor de dados: 31
Autores: Patil,   K.M.; Marothia,   Dinesh K.
In the newly born state of Chhattisgarh a large number of land buyers have become actively engaged in the villages located along the national highway and at the periphery of Raipur city, the capital of Chhattisgarh to purchase prime agricultural land. In view of the fast emerging land markets after the formation of the state, it is imperative to understand the role of market and non-market forces in transaction of prime agricultural land for non-agricultural uses and transactions within the agriculture sector. This study is an attempt in this direction. The study has been conducted in the Jora, Labhandi, Serikhedi and Dharampura villages of Dharsiwa block in Raipur district of Chhattisgarh state.

Agricultural Land Tenure and Carbon Offsets examines the potential role that land ownership might play in determining the agricultural sector’s involvement in carbon sequestration programs. By estimating the carbon sequestration potential of agricultural producers who own most of the land they operate, this report finds that land ownership should not be a constraining factor in agriculture’s ability to provide carbon offsets.

Agricultural markets in Benin and Malawi
Provedor de dados: 31
Autores: Fafchamps,   Marcel; Gabre-Madhin,   Eleni Z.
Based on original trader surveys, this paper examines how agricultural traders operate in Benin and Malawi. Results indicate that the largest transaction costs are search and transport. The use of modern technology is limited. Search methods rely principally on personal visits by the trader, and quality control requires the presence of the trader at the time of purchase. This increases costs, as the trader has to travel a lot, and makes it difficult for trading enterprises to grow. Since enterprises remain very small, personal transport and search time represent a non-negligible share of marketing costs.

Agricultural policies and farm structures.  Agent-based modelling and application to EU-policy reform.
Provedor de dados: 31
Autores: Happe,   Kathrin.
Agricultural structures have been shaped by a variety of factors including economic, cultural, historical, political, technological, and geographical conditions. Moreover, agricultural structures are not static. Structural change can be characterised as an evolutionary process consisting – among other things – of constant adjustment to changes in demand, supply, and technological progress. The development of competitive and efficient agricultural structures has been one of the central goals of agricultural policy making in addition to ensuring a fair standard of living for farmers. To achieve these goals, the agricultural sector in most industrialized nations has long been the subject of government interventions. However, many agricultural policies have...

Agricultural policies in India: Producer Support Estimates 1985-2002
Provedor de dados: 31
Autores: Mullen,   Kathleen; Orden,   David; Gulati,   Ashok.
Since the early 1990s, India has undergone substantial economic policy reform and economic growth. Though reforms in agricultural policy have lagged those in other sectors, they have nonetheless created a somewhat more open economic orientation. In this study, we evaluate the protection and support versus disprotection of agriculture in India. Our methodology involves examining market price support (MPS) for eleven crops, the expenditures on input subsidies benefiting farmers (for fertilizer, electricity and irrigation), and product-specific and total producer support estimates (PSEs) over the period 1985-2002. We draw on the extensive price-comparison and subsidy-measurement data sets and analysis developed earlier by Gulati and his co-authors, often...

Provedor de dados: 31
Autores: Thomas,   Marcelle; Orden,   David.
As in many other developing countries, the concerns about food security in Indonesia during the 1980s and early 1990s resulted in policies aimed at achieving self-sufficiency in food crops. The Government of Indonesia (GOI) combined price interventions and economic incentives to encourage agricultural production, especially of the staple crops. From 1985 to 1998, Indonesia started a series of domestic and trade reforms emanating from a combination of unilateral undertakings, the country’s commitments to the WTO, and the government’s agreement with the IMF following the 1997/98 financial crisis. This study computes nominal protection rates and producer support estimates (NPR and PSE) for Indonesia for the period 1985-2003 for six agricultural commodities,...

Since 1986, Vietnam started to move from a centrally-planned towards a market-oriented system. It underwent several major economic and trade reforms – a process which is still not completed. At the same time, it also started to open its economy. Vietnam has become a member of the ASEAN Free Trade Agreement (AFTA), signed several bilateral trade agreements and is currently negotiating accession to the World Trade Organization (WTO). First positive results of the reform process became visible in the early 1990s when poverty declined to a large extent. Since then, the Vietnamese agricultural sector has also experienced high growth and impressive export achievements. The country changed from a food importer to one of the major exporters worldwide. The question...

Agricultural Policy and Its Impact on Labor Migration from Agriculture
Provedor de dados: 31
Autores: D'Antoni,   Jeremy M.; Mishra,   Ashok K.
Recent generations of farmers have experienced considerable difficulties earning a consistent living wage to support the needs of themselves and their families.  To meet these needs, many farmers and their spouses have increasingly left the agricultural industry to seek employment.  Previous studies have found government policies intended to slow the migration of labor from agriculture have little influence.  Using an autoregressive distributed lag model and adjusting for non-stationary variables in the labor migration equation, direct government payments were found to have a negative and significant effect on labor migration from agriculture.

AGRICULTURAL POLICY AND RURAL DEVELOPMENT
Provedor de dados: 31
Autores: Lazanyi,   Janos.
The Common Agricultural Policy (CAP) is a cornerstone of EU policy relating to rural areas. Initially, it aimed to provide a harmonised framework for maintaining adequate supplies, increasing productivity and ensuring that both consumers and producers received a fair deal in the market. These priorities have shifted to environmental and animal welfare concerns, as well as food safety and security aspects. As a consequence, the CAP has gradually moved from a production-based structure of subsidies to a market-oriented system, integrating standards for food, environment and biodiversity, as well as animal welfare. In 2010, the EU launched an extensive debate on the future of the CAP, as the European Union needs a better tailored, reformed Common Agricultural...

Agricultural Price Transmission Across Space and Commodities During Price Bubbles
Provedor de dados: 31
Autores: Esposti,   Roberto; Listorti,   Giulia.
This paper analyses the horizontal transmission of cereal price shocks both across different market places and across different commodities. The analysis is carried out using Italian and international weekly spot (cash) price data and concentrating the attention on years 2006-2010, a period of generalized exceptional exuberance and consequent rapid drop of agricultural prices. The work aims at investigating how price transmission may be affected during price bubbles. The properties of price time series are firstly explored to assess which data generation process may have eventually produced the observed patterns. Secondly, the interdependence across prices is specified and estimated adopting appropriate cointegration techniques.

Autores: Johnston,   Peter; Islam,   Nazrul.
This paper investigates the impact of an expansion in agricultural processing on the Western Australian economy by modifying and applying a Computable General Equilibrium (CGE) economic model of Western Australia (called WAM). WAM was used to simulate the effects of a $1 million expansion in eight agricultural processing industries. The results show that there is a range of positive impacts from agricultural processing. On average, a $1 million expansion in agricultural processing is estimated to increase the State’s GSP (Gross State Product) by $649,000, and total output by $1.9 million. The expansion of the Wine and spirits industry is estimated to have the largest impact while the Textile fibres, yarns and woven fabrics industry has the smallest impact...

Agricultural Productivity and Anticipated Climate Change in Sub-Saharan Africa: A Spatial Sample Selection Model
Provedor de dados: 31
Autores: Ward,   Patrick S.; Florax,   Raymond J.G.M.; Flores-Lagunes,   Alfonso.
A cereal yield response function is estimated conditional upon environmental and topographical features to detect the effects of spatial heterogeneity and spatial dependence in explaining agricultural productivity across Sub-Saharan Africa. Controlling for direct and localized spillover effects, we then estimate the effect that projected changes in temperature and precipitation as a result of global climate change will have on agricultural production. We find that the estimated declines found in the climatological literature may overestimate actual declines, and factors such as spatial heterogeneity (i.e., country fixed effects) are profoundly more important to agricultural production.

A standardized precipitation index is used in a regression analysis to quantify the impact of climate change on agricultural productivity in Sahel. I first estimate a Malmquist productivity index and its efficiency and technical change components. I further assess the statistical significance of the indices by estimating some confidence intervals via a bootstrap method. In the second stage of the analysis, I use a Probit model to estimate the extent to which climate variables affect agricultural productivity. It appears that agricultural performance has been disastrous in many Sahelian countries from 1970 to 2000. Using a comparable cross-country measure of drought, I provide evidence that precipitation variability is constraining not only Sahel’s...

Autores: Kumar,   Praduman; Mittal,   Surabhi.
The sustainability issue of the crop productivity is fast emerging. The post-Green Revolution phase is characterized by high input-use and decelerating total factor productivity growth (TFPG). The agricultural productivity attained during the 1980s has not been sustained during the 1990s and has posed a challenge for the researchers to shift the production function upward by improving the technology index. It calls for an examination of issues related to the trends in the agricultural productivity, particularly with reference to individual crops grown in the major states of India. Temporal and spatial variations of TFPG for major crops of India have also been examined.

This study examines the role of public agricultural research and development (R&amp;D) in the process of knowledge production and productivity growth in U.S. agriculture from a new perspective.  The seminal work of Griliches (1967) established the relationship between investments in R&amp;D, the process of knowledge production, and the productivity enhancing benefits they create.  In the literature on estimating knowledge production functions measures of multi-factor productivity (MFP) are regressed against measures of knowledge stocks, thereby enabling the researcher to quantify the relationship between the stream of investment expenditures and the productivity enhancing benefits they produce.

Agricultural science and technology policy for growth and poverty reduction
Provedor de dados: 31
Autores: Omamo,   Steven Were; Naseem,   Anwar.
This paper argues that the largely unrealized potential of agricultural science and technology (S&amp;T) in promoting growth and poverty reduction in developing countries results from deeply rooted incompatibility among policy environments, institutional arrangements, and micro conditions and behavior in agricultural research and development (R&amp;D). Achieving growth and poverty reduction based on greater agricultural productivity therefore means achieving greater compatibility among these three dimensions of agricultural innovation systems. Research is sorely needed to build understanding of (1) the “big picture” influencing agricultural S&amp;T policy design and implementation in developing countries, (2) strategies for sustainable funding and delivery...

Achieving agricultural growth and development and thereby improving rural household welfare will require increased efforts to provide yield enhancing and natural resources conserving technologies. Agricultural research and technological improvements are therefore crucial to increase agricultural productivity and thereby reduce poverty. However evaluation of the impact of these technologies on rural household welfare have been very limited by lack of appropriate methods and most of previous research has therefore failed to move beyond estimating economic surplus and return to research investment. This paper evaluates the potential impact of adoption of modern agricultural technologies on rural household welfare measured by crop income and consumption...

AGRICULTURAL WAGES AND FOOD PRICES IN EGYPT: A GOVERNORATE-LEVEL ANALYSIS FOR 1976-1993
Provedor de dados: 31
Autores: Datt,   Gaurav; Olmsted,   Jennifer.
The trend in real agricultural wages in Egypt is described well by an inverted U-shaped curve with a peak around 1985. But the rise and fall of real wages masks a complex dynamic process by which nominal wages adjust in response to changes in food prices. We use governorate-level panel data for 1976–1993 to explore the nature of this adjustment process. Our results indicate that nominal wages adjust slowly. There is a significant negative initial impact of rising food prices on real wages, though wages do catch up in the long run.

Agricultural Water Security and Instream Flows for Endangered Salmonids in Coastal California's Watersheds
Provedor de dados: 31
Autores: Mezzatesta,   Mariano; Newburn,   David A.; Brozovic,   Nicholas.
Many rural landowners within the Western United States do not have access to a secure water supply provided by a major dam or an irrigation district. Such water users must rely instead on groundwater pumping and/or seasonal water flows from tributaries. Some of these agricultural producers choose to store winter stream flows from tributaries within onsite reservoirs to secure their spring/summer water needs. However, regulatory agencies have increased restrictions on surface water storage and diversions to improve instream flows for endangered salmon, thus reducing water security for many landowners not located along the main stem.  The majority of salmon habitat is within the tributaries located throughout a watershed. Most research regarding instream...

Agriculture and the World Trade Organization: Does Membership Make a Difference?
Provedor de dados: 31
Autores: Grant,   Jason H.; Boys,   Kathryn A.
Recent empirical studies have estimated the trade flow effect of membership in the World Trade Organization (WTO) and its predecessor, the General Agreement on Tariffs and Trade (GATT). One important, although largely untested, conclusion from this literature is that the GATT/WTO has worked well if we ignore trade in agriculture – one of the institution’s seemingly apparent failures. This article investigates this conclusion using a large panel of agricultural and non-agricultural trade flows, the latter of which serves as our benchmark. The results are impressive: the multilateral institution has delivered significant positive effects on members’ agricultural trade relative to trade between non-members. Further, despite their special and differential...

Agriculture et qualité de l’eau : le dispositif de Lons-le-Saunier  Evolution des jeux d’acteurs
Provedor de dados: 21
Autores: Martin, Laura; Barataud, Fabienne; Hellec, Florence.
La protection de l’eau est devenue un enjeu majeur depuis le renforcement des obligations réglementaires qui imposent le bon état des masses d’eau d’ici 2015. Les gestionnaires de l’eau sont alors contraints de mettre en place des actions préventives, en intervenant sur les pratiques agricoles situées à proximité des captages d’eau potable. Or ces derniers manquent d’expérience pour inciter le changement de ces pratiques sur un territoire.  C’est dans ce contexte que le programme de recherche Agriculture Biologique et Périmètre de Captage (ABiPeC), mobilise trois équipes de l’INRA et l’ISARA sur les incitations locales à la conversion en agriculture biologique sur les aires d’alimentation de captage et qu’une étude de six mois a été mise en place à l’INRA...

Since the late 1980s, agriculture in Central and Eastern European Countries (CEECs) has been under considerable adjustment pressure due to changing political, economic and institutional environments. These changes have been linked to the transition process, as well as the ongoing integration into the European Union and the world market. Reduced subsidies, increased environmental and food quality demands, as well as structural changes in the supply, processing and food retailing sector call for major structural adjustments and the improvement of farmers’ managerial abilities. Though such changes always carry significant threats to farms, they also offer new opportunities for the farms' entrepreneurial engagement. Upcoming changes in the agricultural...

Agriculture's Contribution to Swiss Climate Policy: Results of an Economic Analysis
Provedor de dados: 31
Autores: Hartmann,   Michael.
Greenhouse gas emissions from Swiss agriculture have been reduced by about 8 % since 1990. Hence, Swiss agriculture has already contributed 13 % to the national Kyoto target, although it is not legally bound to reduce greenhouse gas emissions. Since the reductions are a result of changes of agricultural policy and relative prices, related income losses can not be attributed to climate policy. In other words, the agricultural sector did not have to bear effective emission abatement costs.  If the current agricultural policy is continued, further reductions of agricultural GHG emissions by 3 to 10 % can be expected until 2010. These expectations are based on economic calculations made with the integrated agricultural allocation model S_INTAGRAL. Accordingly,...

Agri-environment Policy Design With Hidden Information and Hidden Action: Input Quotas vs Input Charges
Provedor de dados: 31
Autores: Ozanne,   Adam; White,   Benedict.
Moxey, White and Ozanne (1999) have shown how transfer payments coupled with input quotas can be used to design optimal truth-telling mechanisms for voluntary agri-environmental schemes under hidden information about compliance costs. Ozanne, Hogan and Colman (2001) adapted the Moxey et al. model to analyze hidden action in such schemes, analyzing the relationships between input abatement, the cost of monitoring compliance and farmers’ risk preferences. White (2002) extended the Moxey et al. model to analyze the design of contracts under both hidden action and hidden information, but used an input charge/transfer payment approach rather than the original input quota/transfer payment one. In addition, he assumed that farmers caught cheating face a variable...

Agri-environmental conservation – the case for an environmental levy
Provedor de dados: 31
Autores: Crean,   Jason.
Recent environmental assessments have highlighted the extent of land degradation in Australia and the significant costs involved in addressing it. With projected investment costs running into tens of billions of dollars, it is not surprising that greater attention is now being focussed on who should pay. One idea gathering significant momentum has been the imposition of an environmental levy. Such a levy would raise public funds to be spent on resource degradation issues and has been proposed to work through the taxation system in a similar fashion to the Medicare levy, albeit for a more limited 10 year period. The paper assesses the arguments behind the imposition of an environmental levy and considers some of the issues associated with its effective...

AGRI-ENVIRONMENTAL POLICIES IN A TRANSITIONAL ECONOMY: THE VALUE OF AGRICULTURAL BIODIVERSITY IN HUNGARIAN HOME GARDENS
Provedor de dados: 31
Autores: Birol,   Ekin; Smale,   Melinda; Gyovai,   Agnes.
Agricultural biodiversity is an environmental resource. Much of the agricultural biodiversity remaining in situ today is found on the semi-subsistence farms of poorer countries and the small-scale farms or home gardens of more industrialized nations. The traditional small farms of Hungary are labelled "home gardens" as a reflection of their institutional identity during the collectivisation period. Homesteads managed with family labor, they continue to serve essential food security and diet quality functions during economic transition. Home gardens contribute to the preservation of rural settlements and cultural heritage, and they contain relatively high levels of several components of agricultural biodiversity. The role of home gardens in the...

The rise of a western-style middle class in many successful emerging economies like China currently is inducing deep structural changes on agricultural world markets and within the global agri-food business. As a result of both higher incomes and concerns over product safety and quality the global demand for high-quality and safe food products is increasing significantly. In order to meet the new required quality, globally minimum quality standards are rising and private standards emerging. All over the world these developments cause adjustments at the enterprise, chain and market levels. At the same time, the tremendously increasing demand for renewable energy has led to the emergence of a highly promising market for biomass production. This has...

Agrifood Certification Schemes in an Intercultural Context: Theoretical Reasoning and Empirical Findings
Provedor de dados: 31
Autores: Gawron,   Jana-Christina; Theuvsen,   Ludwig.
The need for adequate systems to guarantee the quality of food products has become more and more obvious in recent years. As a consequence, not only in Germany but throughout the world, the number of certification schemes has been increasing for nearly a decade. Due to the implementation of these standards in various countries, a considerable number of contingency factors exist that may influence the effectiveness and efficiency of such schemes. These factors include the diverse political, economic and social conditions in the different countries. Numerous studies attribute a decisive role in the successful implementation of management instruments to cultural influences. Cultural conditions may differ considerably from region to region around the world....

During three-hundred-year history of the market economy, the main sources of wealth creation have changed from the natural resources (mainly land and relatively unskilled labor with the exception of the master craftsman), tangible material assets (buildings, machinery and equipment, funds) to intangible assets (knowledge and information of all types) that may be contained in the people, organizations, or physical resources. In the later period of the twentieth century, science has acquired the features of direct production force. The term direct implies that unlike the relationship which existed between science and production in the IXX century, where scientific advances was incorporated through the physical labor in the tools, which, in turn, created new...

Most of the pepper species of the genus Capsicum have been recalcitrant to efficient Agrobacterium tumefaciens-mediated stable or transient, genetic transformation. In the present work, we optimized a protocol for transient transformation of the Habanero pepper (Capsicum chinense Jacq.) through the standardization of several experimental factors. These included the age of the plants, the temperature, the length of co-cultivation, the application of a negative (vacuum) and/or a positive (infiltration) pressure, along with micro injection, the use of acetosyringone during the bacterial culturing, and modification of the pH during the GUS assay to eliminate the endogenous &amp;#946;-glucuronidase activity. The standardized protocol, which yielded nearly 55%...

The experimental studies were conducted in 2007-2008, 2008-2009 and 2009-2010 crop seasons, in order to know the agro-economic yield of 'Chinês' and "Macaquinho" taro clones, propagated using huge, extra, large, medium, small and tiny cormels. The harvest was done on average on 202 days after planting, in three crop seasons. Based on the joint analysis of variance carried out, it was observed that taro clones showed significant differences in the yield of fresh and dry weight of leaves, cormels, and commercial and non-commercial comels; besides, there were significant differences in yield of a crop season to another and the size of the cuttings induced significant differences in yield. In the conditions that the experiments were conducted, and considering...

Autores: Freitas,Idelfonso C. de; Santos,Felipe C. V. dos; Custódio Filho,Ronaldo de O.; Correchel,Vladia; Silva,Ruy B. da.
A ausência de restrições climáticas para a produção biológica é a principal característica do bioma Amazônia, o que não se traduz em elevadas produtividades por sucessivos anos de cultivos quando a floresta é substituída por agroecossistemas. O objetivo deste estudo foi avaliar o efeito do manejo do solo nos atributos químicos e físicos do solo pela agricultura familiar, conduzida de forma primitiva. As maneiras de uso avaliadas foram: sistema agroflorestal, pastagem cultivada, roça de toco e mata preservada (usada como referência), todas em Neossolo Quartzarênico. Monólitos de terra foram coletados nas camadas de 0-5, 5-10, 10-20 e 20-40 cm em dois anos agrícolas consecutivos (2010/2011 e 2011/2012) nos meses de julho e janeiro coletando-se sete...

Kniha ukazuje, že k dlouhodobému řešení problémů moderního zemědělství je možno dospět jedině restrukturalizací a takovou správou zemědělských systémů, která změní jejich podobu a fungování na základě agroekologie. Agroekologie je věděcká disciplína, která využívá ekologické teorie ke studiu, designu, managementu a hodnocení produktivních zemědělských systémů, jež současně chrání přírodní zdroje. Kniha se zaměřuje jak na tradiční obhospodařování pro praktické zemědělce tak sofistikované využití ekosystémových poznatků. Kniha slouží jako učebnice pro moderní zemědělský provoz tak pro akademickou obec.

Agro-food chain: an innovative paradigm for food and rural policy analysis and agro-food chain segments’ systemic performance at regional level
Provedor de dados: 31
Autores: Samoggia,   Antonella; Maccani,   Paola; Marchi,   Alan.
The food chain concept is an increasingly common theoretical instrument for food and rural development policy and many countries adopt the so-called “new rural paradigm”, so to integrate different sectoral policies. This paper aims at adopting the food chain paradigm in order to analyse the regional agro-food system and to sustain the design and delivery of consistent inter-sectoral policies. It adopts the netchain concept (Lazzarini et al, 2001) and the theory of governance patterns in global value chains (Gereffi et al, 2005). Results show this innovative approach contributes to better understand and stimulate economic performance of the whole agro-food network.

Agroforestry Policy Review
Provedor de dados: 21
Autores: Smith, Jo.
A lack of policy support is seen as one of the main barriers to wider adoption of agroforestry, with the integration of trees at a low density into agricultural land challenging the conventional specialisation of forestry and agricultural policy mechanisms. Within the EU, it is necessary to examine how agroforestry fits into the two pillars of agricultural support; Pillar I - direct aids and market support, and Pillar II - rural development, as well as within forestry policy schemes for farm woodlands.

AGROHOLDINGS AND CLUSTERS IN KAZAKHSTAN’S AGRO-FOOD SECTOR
Provedor de dados: 31
Autores: Wandel,   Jurgen.
The paper provides an overview of the institutional arrangements on the micro level that have evolved in the agro-food sector of Kazakhstan in the course of transition. Emphasis is laid on more complex arrangements like "agroholdings" and "clusters", hitherto mostly unknown in the agro-food sectors of established market economies. It is shown that "agroholdings" are concentrated mainly in the northern part of Kazakhstan and to a large extent in the grain sector, while in the south a scattered small scale (individual) farm structure has emerged. Parallel to this market-driven development, the Kazakhstani government tries to promote other institutional arrangements that it deems to be of superior competitiveness, especially agro-food clusters. Refering to...

The purpose of this work is to analyze, on the way of the theoretical reference of the neo-corporatism, the new institutional paradigm of the sugar cane mill and the new ways of management and political articulation after the sector deregulation. With the end of the state intervention, there is the explanation of the process of the economical and social differences of the sector between and inside of the productive regions North/Northeast and Center/South. The productive segment is divided in two: the ones with capacity for facing new requests and the ones that don’t have that attribute. It is indispensable to recognize that for its own improvement and growth – considering the institutional limits – the need of self-management rules, whose main challenges...

Agrometeorological models for groundnut crop yield forecasting in the Jaboticabal, São Paulo State region, Brazil
Provedor de dados: 1
Autores: Moreto, Victor Brunini; Rolim, Glauco de Souza.
Forecast is the act of estimating a future event based on current data. Ten-day period (TDP) meteorological data were used for modeling: mean air temperature, precipitation and water balance components (water deficit (DEF) and surplus (EXC) and soil water storage (SWS)). Meteorological and yield data from 1990-2004 were used for calibration, and 2005-2010 were used for testing. First step was the selection of variables via correlation analysis to determine which TDP and climatic variables have more influence on the crop yield. The selected variables were used to construct models by multiple linear regression, using a stepwise backwards process. Among all analyzed models, the following was notable: Yield = - 4.964 x [SWS of 2° TDP of December of the...

ABSTRACT Management of biological nitrogen fixation in common bean still requires improvement. The objective of this study was to verify the compatibility of nitrogen fertilization with biological N2 fixation to increase common bean yield and profitability. Four field experiments were performed in four municipalities of Minas Gerais, Brazil, during the 2009 and 2010 winter crop season. The 2009 crop experiments were set up under a no-till system and the 2010 crop was conducted using conventional tillage. A randomized block experimental design was used with four replications and seven treatments combining application rates of mineral N (at sowing and/or topdressing) and seed inoculation with Rhizobium tropici strain CIAT899. Inoculation with 20 kg ha-1...

Agronomic characteristics of the spring forms of the wheat  landraces (einkorn, emmer, spelt, intermediate bread wheat)  grown in organic farming
Provedor de dados: 21
Autores: Konvalina, Petr; Capouchova, Ivana; Stehno, Zdenek; Moudry, Jan.
Organic farmers look to the possibilities of growing neglected crops, such as the spring forms of hulled wheat – einkorn, emmer and spelt – for support in developing the organic farming system. In 2008, 169 landraces from the gene bank at the Crop Research Institute in Prague were tested on certifi ed organic plots. The experiment was aimed at fi nding suitable varieties for the organic farming system. In summary, our fi ndings show that einkorn (Triticum monococcum L.) and emmer wheat [Triticum dicoccum Schrank (Schuebl)] are resistant to powdery mildew and brown rust, spelt wheat (Triticum spelta L.) is less resistant to these two diseases, and the intermediate forms of bread wheat are very sensitive to such infestation. The  varieties evaluated incline...

In 2009/2010, eight durum wheat cultivars were compared in organic and conventional cropping system in two different locations of south - central Italy. A huge dataset was evaluated, including quality and agronomic traits.   As expected, grain protein content revealed to be the real Achille’s heel for organic productions, seen as average values were not far from the Italian national standard for durum wheat minimum value of protein content (11.5 %). Anyway, values lower than expected were obtained also in conventional management. Protein quality of organically produced grain was as good as the conventional one. No Deoxynivalenol (DON) contamination was recorded in organic durum wheat even in environments where significant DON levels (although clearly lower...

O objetivo deste trabalho foi estimar curvas de progresso de requeima, em genótipos de tomateiro, e identificar grupos de genótipos resistentes à doença. Foram avaliados 25 híbridos de tomateiro, originados de cruzamentos entre quatro variedades comerciais, um acesso do Banco de Germoplasma de Hortaliças (BGH), da Universidade Federal de Viçosa (UFV), e cinco linhagens F8 (Solanum lycopersicum x Solanum habrochaites), estas últimas selecionadas como fonte de resistência à requeima. As plantas foram inoculadas com uma mistura de esporângios de Phytophthora infestans e, em seguida, foram realizadas seis avaliações quanto à severidade de requeima, a intervalos de três dias. Ajustou-se o modelo exponencial aos dados de percentagem de severidade de requeima, e...

Autores: Vasconcelos,Edmar Soares de; Cruz,Cosme Damião; Regazzi,Adair José; Bhering,Leonardo Lopes; Rosado,Tatiana Barbosa; Vasconcelos,Fernando Soares de.
O objetivo deste trabalho foi evidenciar diferenças entre modelos de regressão, obtidos pelo método de Eberhart &amp;amp; Russell, na análise de adaptabilidade e estabilidade de comportamento de genótipos, e propor uma metodologia de agrupamento dos modelos similares. O teste para verificar a identidade de modelos foi empregado em dados de avaliação de 14 genótipos de milho em oito ambientes. Uma vez rejeitada a hipótese de igualdade dos modelos de regressão, realizou-se o agrupamento desses modelos com base no cálculo do quadrado médio da redução (QMRed) entre pares dos modelos de regressão. Após a obtenção desses valores, foi selecionado o de menor magnitude e verificada sua significância pelo teste F. NA hipótese de esse QMRed não ser significativo, o...

Autores: GONZAGA, A. C. de O.
A agricultura em conjunto com as indústrias são os grandes responsáveis por esse desarranjo ambiental. A exploração agrícola, iniciada com a derrubada da floresta nativa até as margens dos cursos d?água, aliada ao uso intensivo do solo e promovendo seu revolvimento, acelera o processo de contaminação e assoreamento dos rios e lagos. Com o advento da irrigação, esses problemas se agravam ainda mais.

Atualmente, a cocoicultura e considerada a segunda cultura frutifera de importancia economica na regiao Nordeste brasileira, tendo os Tabuleiros Costeiros como maiores produtores. Em meados de 1990, ocorreu uma busca acirrada por produtos de coco oriundos ded paises africanos e asiaticos que trabalham com culturas subsidiadas (Sri Lanka, Costa do Marfin, Indonesia e Felipinas). O preco atrativo nao permitia a concorrencia com os produtos de origem nacional, levando os produtos de coco da regiao a situacoes de inviabilizacao de suas culturas. (...) Atualmente, a agua de coco verde consiste em um grande ramo de comercializacao de cocos da variedade anã verde, com acessos notadamente a mercados distantes dos produtores.

Akvakultur - Nye udfordringer og nye muligheder
Provedor de dados: 21
Autores: Jokumsen, Alfred.
Efter en årrække med nationale standarder indførtes et fælles EU regelsæt for økologisk akvakultur d. 1. juli 2010. EU forordningen for økologisk akvakultur rummer et udfordrende regelsæt for de økologiske dambrugere. Derfor forudsætter udvikling og udbygning af den økologiske fiskeproduktion i Danmark en styrket forskningsindsats i forhold til bl.a. foder og ernæring, miljø, produktionsforhold, sundhed og kvalitet. Denne indsats skal bl.a. sigte på at tilpasse produktionen til den nye EU forordning for akvakultur samt øge og effektivisere produktionen af økologiske fisk inden for gældende dansk miljølovgivning på akvakulturområdet.

Al 3+ - Ca2+ INTERACTION IN PLANTS GROWING IN ACID SOILS: AL-PHYTOTOXICITY RESPONSE TO CALCAREOUS AMENDMENTS
Provedor de dados: 126
Autores: Meriño-Gergichevich,C; Alberdi,M; Ivanov,A.G; Reyes-Diaz,M.
High aluminum (Al) concentrations as Al3+ represent an important growth and yield limiting factor for crops in acid soils (pH &amp;#8804;5.5). The most recognized effect of Al-toxicity in plants is observed in roots. However, damages in the upper parts (including stem, leaves and fruits) may also be present. In addition, Al-toxicity triggers an increase in reactive oxygen species (ROS), causing oxidative stress that can damage the roots and chloroplasts, decreasing normal functioning of photo synthetic parameters. Al-toxicity may also increase or inhibit antioxidant activities, which are responsible to scavenge ROS. As result of the negative effects of toxic Al, root metabolic processes, such as water and nutrient absorption, are disturbed with a...

Albania and Trade Liberalization Using our trade advantages in the Free Trade Agreement with EU
Provedor de dados: 31
Autores: Tabaku,   Irma.
According to the World Trade Organization agreements frameworks, individual countries can agree to lower customs tariffs and other trade barriers, in order to open and keep service markets open. In this context, Albania has already concluded free trade agreements with nine countries of the region: Macedonia, Croatia, Bosnia &amp; Herzegovina, Yugoslavia, Moldova, Turkey, Kosovo, Romania, Bulgaria (the last two are EU members now) and by January 2009 the ratification process from the European members’ countries finished. What this means is free exchange of goods and services between these countries by better exploiting their competitive advantages. To better exploit the advantages from free trade at first we need to find out which the Albanian sectors that...

ALBERTA AGRICULTURE AND FOOD TRADE: RECENT TRENDS
Provedor de dados: 31
Autores: Rosario,   Joe A.
Exports have been an integral and essential feature of the agriculture and food industry in Alberta. This is a product of the province’s relatively low population and consumption base on the demand side juxtaposed with a large resource base of prime agriculture land for crop production and an abundance of range and pasture for grazing and forage for raising livestock on the supply side. A host of factors influence the disposition of surplus production or exports including global supply/demand balances, relative cost/price relations, structural changes through farm consolidation and scale economies, market access, exchange rates, sanitary and phyto‐sanitary standards and regulations, disease and pest related issues. The inherent nature of agriculture means...

Provedor de dados: 31
Autores: Emter,   Nicholas A.; Mirus,   Rolf.
Canada and the EU-27 are negotiating a comprehensive economic partnership agreement against the backdrop of the stalled multilateral negotiations under the auspices of the World Trade Organization (WTO). The new agreement is expected to stimulate trade, investment, and technology transfer between the two partners. This report provides a review of the last 15 years of Alberta’s experience in exporting goods to the EU-27, with the goal of gaining insights into how freer trade could affect future exports to the region. First, we summarize the state of bilateral economic relations between the prospective partners, relying in part on a study jointly sponsored by the EU and the Government of Canada. The second part focuses on the exports to the EU from Alberta...

ALBERTA’S EXPORT EXPERIENCE UNDER FREE TRADE AGREEMENTS: 1988 - 2007
Provedor de dados: 31
Autores: Mirus,   Rolf; Tanerguclu,   Hande.
The international involvement of Alberta-based businesses covers trade in goods, trade in services, and Foreign Direct Investment (FDI), both inward and outward. Increasingly FDI is linked to trade in goods and services. Indeed, the export of services like consulting or construction engineering tends to involve the setting up of supporting facilities abroad (outward FDI), and exports of goods frequently necessitate the provision of maintenance services in their wake, either across the border or through an office abroad. Data on outward FDI by Alberta-based firms are not available, nor are data on exports of services by province of origin. Therefore an analysis of what has been happening to Alberta’s international commercial relations is of necessity...

ALBERTA’S EXPORT EXPERIENCE UNDER FREE TRADE AGREEMENTS, 1989-2008: TWENTY YEARS OF FREE TRADE
Provedor de dados: 31
Autores: Mirus,   Rolf; Emter,   Nicholas A.
The period of free trade from 1989 to 2008 coincided with a strong expansion of Alberta’s exports. Our review shows that several factors contributed to this success. In addition to favorable trends in energy and commodity prices, the improved access to the US and Mexican markets that resulted from the CUSFTA and NAFTA are shown to be major causes of the positive development of Alberta’s exports. In particular, the significant increase in manufacturing exports can be attributed to the free trade agreements because manufacturing products face higher tariffs in export markets than do raw materials and energy products. Alberta’s manufacturing sector, therefore, emerges as a major beneficiary of freer trade. As a result, Alberta’s economy has become more...

Alcances y limitaciones de las encuestas de victimización en Ecuador (Política pública)
Provedor de dados: 122
Autores: Santillán, Alfredo.
Las encuestas de victimización se han convertido en uno de los instrumentos más utilizados en el diagnóstico de la inseguridad ciudadana, por cuanto permite conocer en mejor medida la “cifra negra” producida por los bajos niveles de denuncia de hechos delictivos en países como Ecuador. Sin embargo, como todo instrumento de diagnóstico, no son neutrales ni objetivos en su totalidad ya que parten de una serie de supuestos sobre la comprensión de la realidad. Como señalan los especialistas en el tema, la forma que adopta el fenómeno del delito a través de este instrumento depende de la manera en que esté diseñado el cuestionario de la encuesta.

ALCOHOL REGULATION AND CRIME
Provedor de dados: 31
Autores: Carpenter,   Christopher; Dobkin,   Carlos.
We provide a critical review of research in economics that has examined causal relationships between alcohol use and crime. We lay out several causal pathways through which alcohol regulation and alcohol consumption may affect crime, including: direct pharmacological effects on aggression, reaction time, and motor impairment; excuse motivations; venues and social interactions; and victimization risk. We focus our review on four main types of alcohol regulations: price/tax restrictions, age-based availability restrictions, spatial availability restrictions, and temporal availability restrictions. We conclude that there is strong evidence that tax- and age-based restrictions on alcohol availability reduce crime, and we discuss implications for policy and...

A tiririca (Cyperus rotundus) é uma espécie daninha de difícil manejo, causadora da redução do estande e do rendimento em plantios comerciais das mais variadas culturas. Devido à sua agressividade, capacidade de reprodução, alta dispersão e rusticidade, seu controle é difícil e oneroso. Objetivou-se com este trabalho avaliar métodos alternativos de controle da tiririca baseados na alelopatia e na homeopatia. No manejo com alelopatia, testaram-se extratos aquosos de feijão-de-porco (Canavalia ensiformes), mucuna-preta (Stizolobium aterrimum), alecrim-pimenta (Lippia sidoides) e capim-limão (Cymbopogon citratus). Com a homeopatia foi utilizada a escala centesimal hahnemanniana, onde se testaram as dinamizações 3CH, 6CH, 9CH e 12CH. Ambos os experimentos...

A cultura algodoeira é uma atividade agrícola de reconhecida importância socioeconômica, principalmente para o Nordeste brasileiro, onde ela é executada por pequenos agricultores, que representam uma maioria na região, constituindo-se numa importante fonte de geração de emprego e de renda no campo. É uma atividade secular, altamente importante para a agricultura familiar, uma vez que, pelas condições climáticas da região, o algodão é a principal opção fitotécnica, em razão de sua tolerância à seca e pelo fato de possuir mercado potencialmente garantido, já que o Nordeste é o segundo polo de consumo industrial de pluma do Brasil, com quase 300 mil toneladas de pluma por ano. Portanto, os agricultores têm tradição no que diz respeito à cultura. Além disso,...

A strong interest has been focused from several years on the algae pathway for energy production, especially for transportation fuels called third generation biofuel or G3 biofuel, and mainly from microalgae route, considering it could be a high potential alternative strategy for renewable energy and fuel production. Algae, and especially microalgae, present significant advantages compared with land resources, such as much higher productivity and lack of competition with food applications. Nevertheless, based on current knowledge, the production of an algae biomass for energy remains a difficult target to reach, due to the numerous existing hurdles such as the energetic yield and the economic positioning, without neglecting the environmental and societal...

Algoritmo de Gower na estimativa da divergência genética em germoplasma de pimenta
Provedor de dados: 75
Autores: Moura,Maria da Cruz CL; Gonçalves,Leandro SA; Sudré,Cláudia P; Rodrigues,Rosana; Amaral Júnior,Antonio T do; Pereira,Telma NS.
A estimativa da variabilidade genética existente em um banco de germoplasma é importante não só para a conservação dos recursos genéticos, mas também para sua utilização no melhoramento de plantas. Os acessos de um banco são estudados com base em descritores quantitativos e qualitativos. Porém, nem sempre esses dados são analisados simultaneamente. O presente trabalho teve como objetivo estudar a divergência genética entre 56 acessos de Capsicum chinense procedentes da Coleção de Germoplasma da Universidade Estadual do Norte Fluminense Darcy Ribeiro, com base em 44 descritores morfoagronômicos, 37 qualitativos e sete quantitativos, utilizando-se a análise conjunta baseada no algoritmo de Gower. Utilizou-se o delineamento inteiramente ao acaso, com três...

Algoritmos para estimar características físicas en cuencas rurales y su aplicación en el calibrado del método racional, en la región hidrológica No. 12 parcial (Río Santiago)
Provedor de dados: 115
Autores: Martínez-Martínez,Sergio I.; Campos-Aranda,Daniel F.
Los procesos hidrológicos que generan las crecientes son bastante complejos, de manera que su modelación matemática requiere de información pluviográfica e hidrométrica que generalmente no está disponible en la mayoría de las cuencas. Los registros de gastos máximos anuales son los mejores datos para predecir estos eventos y para calibrar métodos de estimación que se puedan aplicar en cuencas similares, sobre todo en las que no están aforadas. Este trabajo comprende el procesamiento de dos tipos de datos. El primero se refiere al de información geográfica en su forma de modelos digitales de elevación (MDE) para obtener el parteaguas, el área de cuenca y las características físicas de su colector principal, incluyendo su selección. Este análisis concluye...

ALGUNAS APLICACIONES DE LA TEORÍA DE SISTEMAS AL DESARROLLO ORGANIZACIONAL
Provedor de dados: 31
Autores: Climent Bonilla,   Juan B.
In the routine of daily activities, and the eagerness to obtain quantitative results, organizations run the risk of becoming absorbed in reductionist notions concerning their task environments (internal and external). This position has counterproductive effects on the learning and renovation capacities of the own organizations, reducing their success and permanence possibilities. The properties and tools of the systemic approach provide information about relevant issues and problems that, in countless cases, are unnoticed by administration and management schemes of rationalist character. Different arguments holding this thesis are exposed through the analysis of several topics and examples.

Algunas características de los inmigrantes ecuatorianos en Murcia y su influencia en el envío de remesas a Ecuador
Provedor de dados: 122
Autores: Vasco, Cristian.
Los flujos de remesas son importantes para la economía ecuatoriana. En este artículo sustentado en una encuesta a migrantes ecuatorianos que trabajan en Totana (Murcia, España), se muestran las diversas tendencias en cuanto al envío de remesas que dependen de la condición familiar de los migrantes. Se resalta el hecho de que los procesos de reagrupamiento familiar inciden en la disminución de las remesas, lo que involucraría una merma de sus volúmenes en el mediano plazo.

Algunas consideraciones acerca de Blastocystissp., un parásito controversial
Provedor de dados: 38
Autores: Kozubsky,Leonora Eugenia; Archelli,Susana.
Blastocystis es un organismo unicelular, anaerobio y uno de los parásitos intestinales de mayor prevalencia a nivel mundial. Durante mucho tiempo su ubicación taxonómica fue difícil de definir. Actualmente es considerado el único parásito humano del Reino Chromista. Se le reconocen numerosas formas evolutivas (vacuolares, granulares, ameboidales, avacuolares, multivacuolares y quísticas) que conforman un ciclo vital aún en estudio. Los quistes son las formas de resistencia y transmisión. Se lo considera un parásito zoonótico con 9 subtipos que pueden tener diferentes especificidades entre hospedadores humanos y animales. Su carácter patógeno ha sido motivo también de controversia dado que puede presentar infecciones asintomáticas o sintomáticas con...

Algunos factores fisiológicos y nutricionales que afectan la incidencia de diarreas posdestete en lechones
Provedor de dados: 108
Autores: Reis de Souza,Tércia Cesária; Mariscal Landín,Gerardo; Escobar García,Konisgmar.
El destete produce perturbaciones en el funcionamiento digestivo y en la salud intestinal de los lechones y casi siempre se asocia con una severa depresión del crecimiento y diarrea. Por ello, con frecuencia se agregan dosis subterapéuticas de antibióticos al alimento como medida preventiva contra las diarreas y como promotores de crecimiento. Sin embargo, debido a la prohibición del uso de antibióticos en la alimentación animal, en diferentes partes del mundo se ha observado un incremento de las diarreas posdestete en lechones. Para contrarrestar este problema se ha promovido el uso de estrategias nutricionales como medidas de control. El presente trabajo tuvo como objetivo revisar algunos aspectos relacionados con la nutrición, la fisiología digestiva,...

Aligning Incentives for Contract Dairy Heifer Growth
Provedor de dados: 31
Autores: Olynk,   Nicole J.; Wolf,   Christopher A.
As dairy farms grow and specialize in milking cows, raising replacement heifers is increasingly outsourced. Perhaps the largest challenge of outsourcing the heifer enterprise involves quality, measured as milk production potential, and the possibility for moral hazard due to hidden action on the part of the custom heifer grower. A principal-agent framework was used to elicit contract terms to provide incentives for the heifer grower to achieve desired growth rates, and enable the return of the heifer to the dairy farm on an accelerated time frame, without sacrificing quality. To mitigate incentive asymmetries, bonuses and deductions are proposed.

Um grande "recall" de alimentos PET ocorrido em 2007 nos Estados Unidos devido à contaminação fraudulenta por melamina, foi ponto chave para o interesse atual sobre novas alternativas alimentares para cães e gatos, a parte a rações comerciais convencionais. A procura por novidades no setor pet food, combinada com uma tendência permanente de humanização na indústria pet, acarreta aumento da procura por alimentos diferenciados para animais de estimação. Dentre os tipos de dietas alternativas encontram-se as dietas naturais, as orgânicas, entre outras. Entretanto, não existem orientações específicas para a fabricação e rotulagem de produtos que contenham carne crua, o que poderia ocasionar desequilíbrios e risco à saúde de proprietários que fornecem esse tipo...

The information gathered during four research cruises carried out in January and February of 2006, 2007 and 2008 allowed to analyze the summer feeding pattern of Illex argentinus squid in the shelf and slope of the Patagonian region (43º S-51º S), SW Atlantic Ocean. Intake, that took place during daytime, had its peak as of midday. Of the preys eaten amphipods and euphausiids, two groups of zooplanktonic organisms, represented 71-99% of the diet. The most frequent preys found in three of the four cruises corresponded to amphipods, represented by a single species, the hyperiid Themisto gaudichaudii, that accounted for over 50% of the food consumed. When depth of the catching area was beyond 100 m an increase in consumption of squid and fish by specimens...

Autores: Udovecz,   Gabor.
Az agrárgazdaság újabb alkalmazkodási feladat előtt áll. A világpiacon – Európában és itthon is – egyszerre erősödik a kereslet a mezőgazdasági termékek iránt az élelmiszerek és a bioenergia piacán. E folyamat egybeesik az éghajlatváltozással összefüggő nagyobb termelési kockázatokkal, valamint a Közös Agrárpolitika soros felülvizsgálatával, illetve az összevont gazdaságtámogatási rendszer (SPS) hazai bevezetésével. A szakértői elemzések, a gazdaságmatematikai modellek különböző eredményei azt valószínűsítik, hogy a jelenleg uralkodó fejlődési trendek, alkalmazkodási és együttműködési készségek mentén a magyar agrárgazdaság 2013-ig inkább lemaradást, mintsem felzárkózást hozó pályára sodródik. Ezen a pályán alig nő a termelés, stagnálnak a reáljövedelmek,...

Autores: Lima,Melissa Pires de; Hilst,Luciana Farhat; Mattana,Fernanda Vanessa Rechinbach; Santos,Cid Aimbiré de Moraes; Weffort-Santos,Almeriane Maria.
The effects of the alkaloid-rich fraction of Himatanthus lancifolius (Müll. Arg) Woodson on normal marrow cells and leukemic cell lines were investigated. After 48 h exposure, the proliferation assay showed significant cell growth inhibition for Daudi (0.1-10 µg/mL), K-562 (1-10 µg/mL), and REH cells (10-100 µg/mL), yet was inert for normal marrow cells. A similar inhibition profile was observed in clonogenic assays. This alkaloid-rich fraction, in which uleine is the main compound, showed no signs of toxicity to any cells up to 10 µg/mL. Cell feature analyses after induction of differentiation showed maintenance of the initial phenotype. Flow cytometric expression of Annexin-V and 7-AAD in K-562 and Daudi cells has indicated that the cells were not...

Állattenyésztési pályázatok a Nyugat-Dunántúl Régióban
Provedor de dados: 31
Autores: Ori,   Aliz; Pogany,   Eva.
A Nyugat-Dunántúl Régióban működő állattartó gazdaságok száma jelentős mértékben csökkent az elmúlt időszakban. A növénytermeléssel és az állattenyésztéssel foglakozók egymáshoz viszonyított aránya egyre távolodik egymástól az utóbbiak rovására. Ismeretes, hogy az állattartó telepeknek a számos közösségi és nemzeti előírásnak való megfeleléshez az Európai Mezőgazdasági és Vidékfejlesztési Alapból (EMVA) finanszírozható pályázatok nyújtanak támogatást.

Allelopathic effects of aqueous extracts of Artistolochia esperanzae O.Kuntze on development of Sesamum indicum L. seedlings
Provedor de dados: 39
Autores: Gatti,Ana Beatriz; Ferreira,Alfredo Gui; Arduin,Marcos; Perez,Sonia Cristina Gualtieri de Andrade.
Aristolochia esperanzae is a climbing plant that occurs in the savanna regions of Brazil. The aim of this work was to identify the effects of aqueous extracts of A. esperanzae on germination, root growth and xylem cell development of sesame seedlings. Leaf and shoot extracts were prepared at concentrations of 1.5 and 3%. Extracts caused marked changes in germination and seedling growth with greatest inhibition produced by root extracts. Morphological changes and decreased growth and development of seedlings were also observed. The extracts of A. esperanzae caused a reduction of 50% in the size of root xylem cells and marked changes in the primary root and in the number of secondary roots.

Allelopathic evidence in exotic guava (Psidium guajava L.)
Provedor de dados: 52
Autores: Chapla,Tatiani Elisa; Campos,João Batista.
The allelopathic activity of the leaf aqueous extract of guava (Psidium guajava L.) on seed germination and root growth in lettuce (Lactuca sativa L.) was studied in an experiment consisting of four replicates with 10 seeds each and extract concentrations of 5, 10, and 20%. Guava allelopathic activity occurred during the germination and growth of lettuce roots at 20% extract concentration, as shown by ANOVA. This result suggested the allelopathic potential of the species. Therefore, the success of P. guajava in invading environments could be partially due to allelopathy. Further studies using other plant parts and field experiments should be conducted.

Allelopathic potential of bark and leaves of Esenbeckia leiocarpa Engl. (Rutaceae)
Provedor de dados: 39
Autores: Souza,Flaviana Maluf; Gandolfi,Sergius; Perez,Sonia Cristina Juliano Gualtieri de Andrade; Rodrigues,Ricardo Ribeiro.
We investigated the inhibitory potential of aqueous extracts of bark and leaves of Esenbeckia leiocarpa Engl. on lettuce germination and early seedling growth. We compared the effects of four concentrations (100, 75, 50 and 25%) of each extract to water and polyethylene glycol (PEG 6000) solution controls for four replicates of 50 seeds for germination and four replicates of ten seedlings for seedling growth. The inhibitory effects of E. leiocarpa extracts on the percentage of germination and on the germination speed seemed to be more than simply an osmotic effect, except for the percentage of seeds germinated in bark extracts. When compared to water control, both bark and leaf extracts delayed germination, and leaf extracts also affected the percentage of...

In this article, we review allelopathy studies conducted in Brazil or involving plant species that occur in the country. Conceptions and misconceptions associated with allelopathy, as well as some international criteria to be applied in allelopathic research, are presented and discussed. We observed a sharp increase in the number of papers on this subject conducted in Brazil between 1991 and 2010. However, most studies are conducted under laboratory conditions, lack a clear hypothesis or a solid justification, and typically make use of target species that do not co-exist with the donor species under natural conditions. We also found that most studies do not take the additional steps in order to purify and identify the bioactive molecules. We recommend that...

Alpha band oscillations track temporal orienting of attention
Provedor de dados: 17
Autores: Gustavo Rohenkohl; Anna Christina Nobre.
Introduction: Recent investigations using field-potential recordings in visual and auditory cortices have shown that oscillatory activity in neuronal ensembles become entrained to the timing of rhythmically presented stimuli according to their modality and location (Lakatos, Chen et al. 2007; Lakatos, Karmos et al. 2008; Lakatos, O&amp;#x27;Connell et al. 2009). In spite of the evidence showing the role of brain oscillations on forming predictions about forthcoming sensory events (for a review (Engel, Fries et al. 2001), little is known about the role of such oscillations in the temporal orienting of attention (Nobre 2001; Coull and Nobre 2008). To test the effect of temporal orienting of attention on early perceptual processing, motor selection, and...

Alpha-1-antitrypsin (AAT) plays an important role in the pathogenesis of emphysema, the pathological lesion underlying the majority of the manifestations of Chronic Obstructive Pulmonary Disease (COPD). In this study we tested the hypothesis that common AAT polymorphisms influence the risk of developing COPDs. We investigated PiM1 (Ala213Val), PiM2 (Arg101His), PiM3 (Glu376Asp), PiS (Glu264Val) and PiZ (Glu342Lys) SERPINA1 alleles in 100 COPD patients and 200 healthy controls. No significant differences were observed in allele frequencies between COPD patients and controls, neither did haplotype analysis show significant differences between the two groups. A cross-sectional study revealed no significant relationship between common SERPINA1 polymorphisms...

Alterações estruturais e fisiológicas em sementes de Copaifera Langsdorffii DESF. - Leguminosae-Caesalpinioideae submetidas ao tratamento com hipoclorito de sódio
Provedor de dados: 95
Autores: Noleto,Leonardo Gonçalves; Pereira,Maria de Fátima Rodrigues; Amaral,Lourdes Isabel Velho Do.
O objetivo deste trabalho foi determinar o efeito do hipoclorito de sódio (NaClO) sobre a testa das sementes, germinação e o estabelecimento de plântulas de copaíba. A remoção da cutícula da testa de sementes após imersão em NaClO a 2,5% foi evidenciada pelo corante Sudan IV e microscopia eletrônica de varredura. Com a remoção dessa camada ocorreu aumento significativo na absorção de água pela semente, durante a fase inicial da embebição. Substâncias fenólicas, provavelmente inibitórias da germinação, foram detectadas com cloreto férrico nas paredes celulares dos cotilédones. A imersão em NaClO foi mais favorável para a emergência de plântulas (54%), quando comparada com a escarificação mecânica (2%) e controle (14%). Esses resultados permitem concluir que...

Alterações no Código Florestal Brasileiro: impactos potenciais sobre a ictiofauna
Provedor de dados: 49
Autores: Casatti,Lilian.
É apresentada uma análise dos possíveis impactos que a diminuição da vegetação nativa, notadamente das florestas ripárias, pode causar sobre a ictiofauna. Três conjuntos de aspectos funcionais primordiais desempenhados pelas florestas ripárias são discutidos: transferência de energia solar ao ambiente aquático, interceptação de nutrientes e sedimentos que adentram nos rios e trocas de material orgânico entre o sistema terrestre e aquático. Conclui-se que qualquer alteração que se traduza em mais perdas de vegetação nativa, seja em áreas de preservação permanente ou em reservas legais, pode gerar perdas de espécies, homogeneização faunística e diminuição de biomassa íctica.

Rice is a tropical plant, so cold temperature may be detrimental to its development, depending on the genotype and environmental conditions. Degree of lipid unsaturation has been related to cold tolerance due to its effect on membrane stability. So, the aim of this study was to characterize the fatty acid composition and its alterations due to cold temperature in rice genotypes of diversified origin. Forty-four rice genotypes at the V4 stage were submitted to two temperature conditions: 10°C and 28°C for two days and after this they had their leaves collected for lipid extraction and quantification. Control plants were allowed to regrow until presenting four leaves fully expanded and then were subjected to 10°C for ten days for cold tolerance evaluation....

Gliomas are the most common tumors in the central nervous system, the average survival time of patients with glioblastoma multiforme being about 1 year from diagnosis, in spite of harsh therapy. Aiming to study the transcriptional profiles displayed by glioma cells undergoing cisplatin treatment, gene expression analysis was performed by the cDNA microarray method. Cell survival and apoptosis induction following treatment were also evaluated. Drug concentrations of 12.5 to 300 μM caused a pronounced reduction in cell survival rates five days after treatment, whereas concentrations higher than 25 μM were effective in reducing the survival rates to ~1%. However, the maximum apoptosis frequency was 20.4% for 25 μM cisplatin in cells analyzed at 72 h,...

We evaluated the antiproliferative effect of infusions from Pluchea sagittalis using the Allium cepa test. Infusions in three concentrations (2.5, 5, and 25 g dm-3) of leaves cultivated in three environments (in vitro, acclimatized growth chamber, and field) were used. Six onion bulbs were used for each of the eight treatments, and the mitotic index was obtained from 6000 cells per treatment. In conclusion, leaf infusions of P. sagittalis cultivated in the field have a high antiproliferative activity, as well as the cultivation system influences the antiproliferative potential.

Considerable progress has been made  towards understanding the role of diet on enhancing the nutritional value of ruminantderived  foods while more recent studies have attempted to elucidate the molecular  mechanisms underlying the changes in milk and tissue lipid fatty acid composition in  ruminants. Diet is the major environmental factor influencing the CLA content of  ruminant milk whilst the effects of genotype, stage of lactation and parity are  relatively minor (Palmquist el al. 2005). Concentrations of CLA in ruminant meat are  dependent on diet, gender, slaughter weight and breed with evidence of variable  enrichment...

Autores: SANTOS, R. S. S. dos; LEOLATO, L. S.; SOUZA, R. B. de.
Estudos de bioecologia de insetos permitiram aprofundamento no conhecimento de fatores que governam relações ecológicas em agroecossistemas. Nesta linha, se destaca a evolução do conhecimento sobre comunicação química de insetos. Dentre as substâncias responsáveis pela comunicação intraespécifica merece destaque os feromônios. Feromônios são substâncias químicas secretadas por um indivíduo com função de comunicação dentro da espécie. A disruptura sexual é uma técnica de controle que visa proteger o agroecossistema por introdução de elevada quantidade de feromônio, com função de dificultar o encontro sexual. Esta tecnologia atua nas populações por meio de cinco mecanismos: diminuição da resposta em função da habituação e adaptação; camuflagem; atração...

Alternativa para diminuição de passivo ambiental decorrente de análise do C da biomassa microbiana do solo.
Provedor de dados: 14
Autores: KNUPP, A. M.
No procedimento convencional para quantificação do carbono da biomassa microbiana, que vem sendo adotado no laboratório de Biologia do Solo, o teor de carbono microbiano das amostras de solo é quantificado a partir de sua digestão com uma solução ácida de dicromato de potássio. Essa solução é tóxica, além de gerar um resíduo ácido contendo um metal pesado (cromo), após o processo de digestão. Uma adaptação para esse método foi testada visando à redução do volume da solução ácida de dicromato de potássio utilizada, o que acarretaria menor risco na manipulação e menor passivo ambiental.

Alternative control of Tetranychus evansi Baker &amp;amp; Pritchard (Acari: Tetranychidae) on tomato plants grown in greenhouses
Provedor de dados: 82
Autores: Soto,Alberto; Venzon,Madelaine; Oliveira,Rafael M; Oliveira,Hamilton G; Pallini,Angelo.
Tetranychus evansi Baker &amp;amp; Pritchard is an important pest of solanaceous plants, including tomatoes. This mite is characterized by a high reproductive rate, which leads to high population growth in a short period of time causing important economic damage. Control of T. evansi is mainly through synthetic acaricides. In searching for environmentally friendly control measures, we evaluated the efficiency of alternative products to control T. evansi on tomato plants under greenhouse conditions. The products tested were lime sulphur and neem based products. We first estimated the lethal concentration (LC) and instantaneous rate of increase (r i) of T. evansi exposed to different product concentrations in laboratory conditions, and later tested the...

The boll weevil causes serious damage to the cotton crop in South America. Several studies have been published on this pest, but its phenology and behavior under the tropical conditions prevailing in Brazil are not well-known. In this study the feeding behavior and main food sources of adult boll weevils throughout the year in Central Brazil was investigated. The digestive tract contents of insects captured in pheromone traps in two cotton fields and two areas of native vegetation (gallery forest and cerrado sensu stricto) were analyzed. The insect was captured all through the year only in the cerrado. It fed on pollen of 19 different plant families, on Pteridophyta and fungi spores and algae cysts. Simpson Index test showed that the cerrado provided...

ALTERNATIVE FUTURES OF RURAL AREAS IN THE EU: A COMPARATIVE ANALYSIS OF SCENARIO STUDIES
Provedor de dados: 31
Autores: Jansson,   Kristina M.; Terluin,   Ida J.
What does rural Europe look like in 2030? Is agriculture still the main land user? In recent years, studies such as ESPON, Eururalis, SCENAR2020, SENSOR, SEAMLESS and PRELUDE have tried to address these questions. These studies resulted in a number of alternative futures of rural areas in the EU. In this paper a comparative analysis of these scenario studies is made in order to explore differences and similarities in the scenarios and alternative futures of rural areas in the EU. For this purpose, we designed a scheme for assessing the properties of the various scenarios and a scheme for a systematic description of the rural futures according to the scenarios. It appears that most scenario studies use a baseline scenario and a set of alternative scenarios...

Alternative Land Use Policies: Real Options with Costly Reversibility
Provedor de dados: 31
Autores: Song,   Feng; Zhao,   Jinhua; Swinton,   Scott M.
This paper adopts a real options framework to evaluate the cost-effectiveness of four types of subsidies that aim to encourage a socially desirable land use under return uncertainties and costly reversibility of land use change.  We first present a land conversion model to show how the subsidies that are expected net present value (ENPV) equivalent can change a representative farmer’s optimal land conversion rules differently for converting land into an alternative use as well as converting out of it. This is because these subsidies affect the land conversion costs, land return level and uncertainty differently. Then in the context of encouraging energy crop production, we compare the probabilities of inducing the representative farmer to convert land from...

Autores: Vieira,Bruno Guilherme Torres Licursi; Vieira,Roberval Daiton; Krzyzanowski,Francisco Carlos; França Neto,José de Barros.
The growing demand for high quality soybean [Glycine max (L.) Merrill] seeds requires a precise seed quality control system from the seed industry. One way to accomplish this is by improving vigor testing. Cold test has been traditionally employed for corn seeds. However, it has also been used for other seed crops such as cotton (Gossypium spp.), soybean (Glycine Max), dry bean (Phaseolus vulgaris) and pea (Pisum sativum). This study was carried out with the objective of adjusting an alternative procedure for the cold test to determine soybean seed vigor. Six commercial soybean seed lots of the cultivar BRS 133 were used. The physiological potential of the seed lots was evaluated by germination on paper towel and sand box, seedling field emergence,...

Alternative techniques to study characters of the genitalia in Lepidoptera
Provedor de dados: 82
Autores: Dias,Fernando M S; Casagrande,Mirna M; Mielke,Olaf H H.
The present note aims to describe two alternative methods for observing genitalia in Lepidoptera. The first one provides means to examine both male and female genitalia without spoiling the scales of the abdomen, preserving it attached to the thorax and aesthetically similar to an unexamined specimen. The second one provides ways of observing certain characters on the male genitalia in a non-destructive way, and does not depend on time-consuming removing and dissection of the abdomen. It is expected that the presented techniques will help on morphological studies and on identifying similar species which consistently differ in genitalic armatures.

Alternatives for methane emission mitigation in livestock systems
Provedor de dados: 96
Autores: Lascano,Carlos E.; Cárdenas,Edgar.
Human activities are contributing to Global Climate Change through the production of Green House Gases (GHG), which result in increased air, land and ocean temperatures and extreme changes in precipitation in regions of low and high rainfall. The most important GHG's are carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). It is estimated that 18 % of the annual GHG emissions come from different types of livestock and that 37% of CH4, with higher global warming potential (23) relative to CO2 (1), comes from fermentation processes in ruminants. It is possible that in the future beef and milk exports from producing countries is subject to bans if cattle systems do not comply with measures to reduce GHG. There are several alternatives available and...

The objective of the UE-funded program REPCO (FP6) was to identify new alternatives to copper fungicides in organic farming. Two pathogens have been considered: grapevine downy mildew (Plasmopara viticola) and apple scab (Venturia inaequalis). Research on grapevine was carried out by GRAB (Avignon, France) and FEM-IASMA (San Michele all’Adige, Italy). Trials were carried out under natural conditions in order to test reduced doses of copper and copper-free alternatives. Five-year trials proved that copper is the best fungicide. However, the use of new low copper rate formulations and the association of copper-free alternatives with reduced doses of copper or with reduced number of copper applications (limited to the most susceptible grapevine growth stages)...

ALTERNTIVE PROTECTION OF BIOPOTATOES IN ORGANIC FARMING
Provedor de dados: 21
Autores: Tomasek, Jaroslav; Dvorak, Petr.
There were tested water extracts from Syringa vulgaris and Pyrethrum parthenium. They did not prove significant differences of decrease of the air attack of Colorado potato beetle (Leptinotarsa decemlineata), the activity of eggs – laying and the occurrence of larvae in comparison to the control. Interesting trends of lower-eggs lying and a lower larvae occurrence were discovered. The liquid spray against the late blight (Phytophthora infestans) did not significantly decrease neither occurrence of late blight or the yield.  The production of the bio-potatoes is only 0,2 % of all potatoes production in the Czech Republic. The aim of this experiment was to try alternative methods of regulation of Colorado potato beetle and late blight (the biggest harmfull...

Altitudinal distribution of birds in a mountainous region in southeastern Brazil
Provedor de dados: 103
Autores: Mallet-Rodrigues,Francisco; Parrini,Ricardo; Pimentel,Leonardo M. S.; Bessa,Rafael.
We studied the altitudinal distribution of 426 bird species in the Serra dos Órgãos, a mountainous region in southeastern Brazil. Thirty-four localities were visited between 1991 and 2009. Our study revealed a decline in bird species richness with elevation, although a smaller number of species was recorded at lower altitudes (below 300 m) possibly due to local extinctions caused by the intense human occupation of the region. A less diverse avifauna was found above 2,000 m, with only one species (Caprimulgus longirostris) recorded exclusively in this altitudinal range. Most endemic species were found between 300 and 1,200 m, but the endemism was more significant at higher altitudes. Nearly half of the birds found above 1,400 m were endemic species. Most of...

Aluminum hydroxy-interlayered minerals and chemical properties of a subtropical Brazilian Oxisol under no-tillage and conventional tillage
Provedor de dados: 90
Autores: Inda,Alberto Vasconcellos; Torrent,José; Barrón,Vidal; Bayer,Cimélio.
No tillage systems significantly influence the soil system, but knowledge about the effects on the mineralogy of tropical and subtropical soils is limited. This study evaluated the long-term effects (26 years) of no-tillage (NT) on aluminum hydroxy-interlayered minerals of a subtropical Oxisol in Southern Brazil (Guarapuava, PR), compared to the same soil under conventional tillage (CT). The clay fraction (&lt; 2 µm) in soil samples of the surface horizons of a field experiment under both management systems was analyzed by X-ray diffraction (XRD) to identify and characterize Al hydroxy-interlayered minerals before and after treatment with sodium citrate to remove intra-layer material. Soil liquid (solution) and solid phases were also characterized. The...

Autores: Pongraczne Barancsi,   Agnes.
Magyarországon az utóbbi néhány évben kardinális szerepet kap a jó minőségű búza előállítása, mely mind elméletében, mind gyakorlatában jelentős felkészültséget igényel. Az őszi búza minőségvizsgálatakor elsősorban a külföldi, de egyre gyakrabban a hazai vásárlók is igénylik az alveográfos paraméterek megadását is. A „Pannon” minőségnek fontos paraméterei az alveográfos W és P/Lértékek. Acsekély számú hazai és külföldi szakirodalmi adatok, valamint saját tapasztalataink és vevőink igénye alapján alveográfos sütőipari kategóriákat állítottunk fel. Az osztályozás fontosságát az adta, hogy a vizsgált évek klimatikusan teljesen eltérőek voltak. Afajták eredményei tükrözik, illetve magukban foglalják a fajták eltérő évjáratban kifejeződött minőségét is....

Álvita a tagállam földre fennálló önrendelkezésének közösségi jogalapjáról

Autores: Tanka,   Endre.
A földpiacra kötelező közösségi jogalapot a Csatlakozási Szerződés (CsSz) a Római Szerződés (RSZ) 56. cikkében rögzíti. Az EB által ehhez fűzött jogértelmezés megvilágítja a tőke kivételes korlátozhatóságát, tehát azt is, amivel a közösségi jog a földügyben lehetővé teszi a tagállami érdeknek a közösségi értékrenddel egyeztethető érvényesíthetőségét. Történetileg és tulajdoni rendjüket tekintve, az EU15 tagállama az RSZ 295. (ma 345.) cikkével kizárja, hogy az EU beavatkozzék az államterületüket érintő földtulajdoni önrendelkezésükbe. E jogintézmény a keleti belépőknél – így esetünkben is – az RSZ 56. cikkének kötelező érvénye és tartalma miatt elesik. Nem cáfolható, hogy az EU-15, másfelől az EU-12 tagjainak földjogi státusát ma két, lényegesen eltérő...

The Amazonian rainforest is arguably the most species-rich terrestrial ecosystem in the world, yet the timing of the origin and  volutionary causes of this diversity are a matter of debate. We review the geologic and phylogenetic evidence from Amazonia and compare it with uplift records from the Andes. This uplift and its effect on regional climate fundamentally changed the Amazonian landscape by reconfiguring drainage patterns and creating a vast influx of sediments into the basin. On this “Andean” substrate, a region-wide edaphic mosaic developed that became extremely rich in species, particularly in Western Amazonia. We show that Andean uplift was crucial for the evolution of Amazonian landscapes and ecosystems, and that current biodiversity patterns...

Ambient levels and occurence of persistent organic pollutans (POPs) in the airshed of a mediterranean coastal lagoon
Provedor de dados: 5
Autores: Castro-jimenez, Javier; Mariani, G.; Vives, I.; Skejo, A.; Umlauf, G.; Zaldivar, Jose-manuel; Messiaen, Gregory; Laugier, Thierry.
Persistent organic pollutants (POPs) present in the airshed of a given environment may participate in exchange / deposition processes that will determine their inputs to the terrestrial or aquatic ecosystems. In addition, physico-chemical properties of POPs may favour long range atmospheric transport to other areas, even reaching remote zones. It is therefore important to determine the airshed POPs concentration in order to evaluate the potential amounts that may participate in the mentioned processes. Coastal lagoons are characterized by a high biodiversity and intense primary production leading to both ecological and economical considerable importance. Thau lagoon seems to be under intense anthropogenic pressure (urban, industrial, agricultural and shell...

Ambient-Based Policy Instruments: The Role of Recommendations and Presentation
Provedor de dados: 31
Autores: Spraggon,   John M.; Oxoby,   Robert J.
We explore the effects of recommended play and the presentation of payoff information on behavior in an ambient-based policy instrument experiment. Specifically, we test the effects of recommended play (via a description of marginal decision making) and a payoff table on the behavior of individuals facing an ambient-based policy instrument. We find that recommended play and the presentation of a payoff table increases the use of the socially optimal strategy, thereby increasing efficiency. These results suggest that providing decision makers with a richer description of the decision making environment significantly reduces decision error, significantly improving the efficiency of ambient-based policy instruments.

Autores: Victor B. Ivanov.
AMBIGUOUS DEPENDENCE OF MINIMAL PLANT GENERATION TIME ON NUCLEAR DNA CONTENT Victor B. Ivanov The minimum generation time (MGT) of plant development was suggested to depend on nuclear DNA content, which varies in plants over wide limits1. In ephemeral species with the shortest MGT, the average C values were significantly lower than in annual species, whereas the average C values in annual species were lower than those in perennial plants. However, nobody has paid attention to the ratio of annual to perennial species number as a function of C values. Here I show that with increasing C the ratio of annual to perennial species increases to C values equal to 7-8 pg (monocots) and 6-7 pg (eudicots) and then decreases and that the fraction of annuals is abundant...

Provedor de dados: 61
Autores: Sheokand,Sunita; Bhankar,Vinita; Sawhney,Veena.
Accumulation of salts in irrigated soils is one of the primary factors limiting yield in South Asia. We investigated whether exogenous nitric oxide (NO) supplementation as sodium nitroprusside has any ameliorating effect against NaCl induced oxidative damage in chickpea leaves. NaCl treatment (250 mM) alone and in combination with two concentrations of SNP (0.2 and 1 mM) were given to 50 days old chickpea plants for 2, 4 and 6 days. Salt stress adversely affected the relative membrane injury, lipid peroxidation levels, relative water content (RWC) and H2O2 content. The effect was time dependent. SNP treatments could ameliorate the toxic effect of short term salt stress of 2 days on relative membrane injury and partial amelioration was observed with 4 and 6...

Améliorer l’autonomie azotée des systèmes céréaliers en agriculture biologique : Incidence de l’association blé-légumineuses fourragères sur la qualité technologique du blé.
Provedor de dados: 21
Autores: Madelin, Camille.
Le développement des systèmes céréaliers sans élevage en Agriculture Biologique conduit à une utilisation croissante et coûteuse d’azote exogène à la ferme. L’utilisation des légumineuses sous couvert de blé est une solution qui permet de répondre à ces objectifs. Cette étude a été conduite pendant l’année 2008-2009 sur cinq parcelles d’agriculteurs de Rhônes Alpes dans le but d’améliorer l’autonomie azotée des cultures et d’évaluer l’incidence des légumineuses sur la qualité du blé biologique. Une première recherche a été effectuée sur la dynamique des ressources azotées afin de comprendre l’influence de la légumineuse sur la nutrition azotée du blé. Une seconde approche a montré l’incidence du couvert sur le fractionnement des différentes protéines du...

Autores: Alfonso,P.
Los virus influenza de origen animal amenazan la humanidad por la ocurrencia de zoonosis y ocasionalmente por la emergencia de pandemias, como los tres eventos ocurridos el pasado siglo, cada uno de los cuales ocasionó millones de muertes. Actualmente se asiste a otra pandemia que, en menos de cuatro meses, se ha difundido a 174 países y territorios en todos los continentes, generando más de doscientos diez mil casos, aunque con una letalidad total del 0.89%. Este último evento coexiste con otras amenazas por virus influenza de implicaciones para la salud pública que pudieran agravarlo o cuando menos sucederlo. La identificación de peligros es el paso inicial e imprescindible para la planificación de la reducción de riesgos. Determinadas prácticas de...

American cutaneous leishmaniasis (ACL) was investigated in dogs from an urban endemic area in Cianorte, Paraná state, Brazil. Of 169 studied dogs, none presented suspected ACL lesions. Eleven animals (6.6%) had anti-Leishmania braziliensis antibodies (titers &gt; 40) detected by the immunofluorescent antibody test (IFAT) while four (2.4%) showed L. braziliensis-complex DNA by the polymerase chain reaction (PCR). Although no associations were found between IFAT or PCR results and age, sex, origin, free-roaming animals or length of residence at the address, the majority of IFAT- or PCR-positive dogs were from the urban area of the city and were allowed to roam freely beyond their neighborhood. The presence of anti-Leishmania braziliensis antibodies and L....

American Native Beef Cooperative
Provedor de dados: 31
Autores: Kenkel,   Philip L.; Holcomb,   Rodney B.
The American Native Beef project involved a failed attempt to establish cow and bull slaughter operation in Southeast Oklahoma. The effort was initially organized as a new generation cooperative and raised over US$2.5M from area producers who retained their funds in escrow for over 5 years despite numerous opportunities to withdraw their investment. The business model was restructured several times to attract equity capital from outside investors. The case provides insights into the linkages between business strategy and business structure. It also raises the question as to whether the project could have been successful under the original business model.

American farms encompass a wide range of sizes, ownership structures, and business types, but most farms are still family farms. Family farms account for 98 percent of farms and 85 percent of production. Although most farms are small and own most of the farmland, production has shifted to very large farms. Farms with sales of $1 million or more make up less than 2 percent of all farms, but they account for 48 percent of farm product sales. Most of these million-dollar farms are family farms. Because small-farm households rely on off-farm work for most of their income, general economic policies, such as tax or economic development policy, can be as important to them as traditional farm policy.

American farms vary widely in size and other characteristics, but farming is still an industry of family businesses. Ninety-eight percent of farms are family farms, and they account for 82 percent of farm production. Small family farms make up most of the U.S. farm count and hold the majority of farm assets, but they produce a modest share of U.S. farm output. In contrast, large-scale family farms and nonfamily farms—only 12 percent of all farms—account for 84 percent of farm production. Small farms are less profitable than large-scale farms, on average, and the households operating them tend to rely on off-farm income for their livelihood. Because small-farm households receive most of their income from off-farm work, general economic policies—such as tax...

America’s Organic Farmers Face Issues and Opportunities
Provedor de dados: 31
Autores: Greene,   Catherine R.; Slattery,   Edward; McBride,   William D.
Organic agriculture has established a foothold in many U.S. farm sectors, particularly among horticultural specialties, but the overall use of organic practices lags behind that of many other countries. Recent data from several producer surveys illustrate notable differences and similarities between organic and conventional farmers. Emerging issues in the organic sector include dampened consumer demand resulting from the weaker U.S. economy and potential competition from new labels like the “locally grown” label.

Amino acid digestibility and poultry feed formulation: expression, limitations and application
Provedor de dados: 96
Autores: Bryden,Wayne L.; Li,Xiuhua.
The nutritional value or quality of dietary proteins used for poultry feed formulation varies: amino acid availability is an important measure of protein quality. Determination of ileal digestibility values has become the preferred method for estimating amino acid availability. This review discusses the different approaches to the expression of digestibility results, including correction for endogenous loss and the derivatisation of standardised values. Sources of variation in values include, the assay protocol, anti-nutritional factors in feedstuffs and feed milling. Feed formulating with ileal digestibility values should allow higher dietary inclusion levels of protein feedstuffs of lower quality provided that values of different feedstuffs are additive,...

Amino acid features: a missing compartment of prediction of protein function
Provedor de dados: 17
Autores: Esmaeil Ebrahimie; Mansour  Ebrahimi; Mahdi  Ebrahimi.
Enormous computational efforts have been carried out to predict structure and function of protein. However, nearly all of these efforts have been focused on prediction of function based on primary nucleic acid sequence or modeling 3D structure of protein from its nucleic acid sequence. In fact, it seems that amino acid attributes, which is an intermediate phase between DNA/RNA and advanced protein structure, has been missed.&amp;#xd;&amp;#xa;From 2010, we examined the possibility of precise prediction of structural protein function based on amino acid features by improving the following three aspects of amino acid research: (1) Increasing the number of computationally calculated amino acid features, (2) Testing different feature selection (attribute...

The curation process is significantly slowed down by missing information in the articles analyzed (for example, the identity of the clones used to generate ISH probes, the precise sequences tested in reporter assays, etc..). To help authors ensure in the future that necessary information is present in their article, we defined the Article Minimum Information Standard (AMIS) guidelines. This standard describes for each experiment the mandatory information that should be mentioned in literature articles to facilitate the curation process. These guidelines extend the minimal information defined by the MISFISHIE format (Deutsch at al. 2008, _Nature Biotechnology_). This standard was deduced from the ANISEED curation pipeline (Tassy, Dauga, Daian, Sobral et al....

Ammonia volatilization in no-till system in the south-central region of the State of Paraná, Brazil
Provedor de dados: 90
Autores: Fontoura,Sandra Mara Vieira; Bayer,Cimélio.
Ammonia (NH3) volatilization can reduce the efficiency of urea applied to the surface of no-till (NT) soils. Thus, the objectives of this study were to evaluate the magnitude of NH3 losses from surface-applied urea and to determine if this loss justifies the urea incorporation in soil or its substitution for other N sources under the subtropical climatic conditions of South-Central region of Paraná State, Brazil. The experiment, performed over four harvesting seasons in a clayey Hapludox followed a randomized block design with four replicates. A single dose of N (150 kg ha-1) to V5 growth stage of corn cultivated under NT system was applied and seven treatments were evaluated, including surface-applied urea, ammonium sulfate, ammonium nitrate, urea with...

Ammonium chloride as nitrogen source in sugarcane harvested without burning
Provedor de dados: 90
Autores: Vieira,Michele Xavier; Trivelin,Paulo Cesar Ocheuze; Franco,Henrique Coutinho Junqueira; Otto,Rafael; Faroni,Carlos Eduardo.
The great difficulty of incorporation of N fertilizers into the "green sugarcane" system causes concern and since urea is the most commonly used source, there is the risk of loosing NH3 through volatilization. For this reason, a field experiment was undertaken (in a Hapludox Typic) with the objective of evaluating the agronomic efficiency of ammonium chloride on stubble of the second ratoon (SP89 1115), as well as its residual effect on the subsequent cycle (third ratoon). The experimental design was randomized blocks with four replications. Treatments consisted of three N rates (60, 120 and 180 kg ha-1 N) in the form of NH4Cl, in addition to a control treatment without the addition of N fertilizer. The ratoon cane of the second cutting was harvested in...

Para a recomendação de calagem e adubação, objetivando uma produção economicamente viável e ambientalmente correta, é fundamental a análise química do solo. Esta análise avalia a acidez (pH), a disponibilidade de nutrientes (P, K, Ca e Mg) ou a presença de alumínio (Al) no solo, em nível tóxico para as culturas, de forma rápida e a baixo custo. A primeira e mais crítica etapa da análise química refere-se ao processo de amostragem do solo. Alguns passos devem ser observados nessa fase, pois um erro na amostragem poderá comprometer as etapas seguintes na definição das quantidades de calcário e fertilizantes a serem aplicadas na cultura. A época de amostragem varia com o manejo do solo, a cultura e outros fatores. Para culturas anuais, recomenda-se que a...

Amostragem foliar da bananeira 'Prata-Anã
Provedor de dados: 94
Autores: Rodrigues,Maria Geralda Vilela; Pacheco,Dilermando Dourado; Natale,William; Silva,José Tadeu Alves da.
Para diagnose nutricional da bananeira, é necessário padronizar a amostragem do tecido a ser utilizado, já que a composição mineral varia com a idade da planta, com a folha amostrada, entre as diversas partes da folha, ao que se somam as condições ecológicas, diferenças varietais e flutuações sazonais dos elementos. Portanto, a possibilidade de equívoco na interpretação é considerável. O Método de Amostragem Internacional de Referência (MEIR) para bananeira recomenda coletar a terceira folha de plantas com cachos que apresentem todas as pencas visíveis e não mais que três mãos de flores masculinas abertas, retirando-se a metade interna de uma faixa central do limbo, desprovida da nervura central. Há uma dificuldade em seguir tal recomendação para bananeira...

AmpC beta lactamases among Gram negative clinical isolates from a tertiary hospital, South India
Provedor de dados: 58
Autores: Mohamudha,Parveen R.; Harish,B.N.; Parija,S.C.
AmpC β-lactamases are cephalosporinases that hydrolyze cephamycins as well as other extended-spectrum cephalosporins and are poorly inhibited by clavulanic acid. Although reported with increasing frequency, the true rate of occurrence of AmpC β-lactamases in different organisms, including members of Enterobacteriaceae, remains unknown. The present study was designed to determine the occurrence of AmpC enzyme-harbouring Gram-negative clinical isolates in a tertiary care hospital in Pondicherry state, South India. A total of 235 Gram negative clinical isolates were tested for resistance to cefoxitin, third generation cephalosporin (3GC) antibiotics, ampicillin, amikacin, co-trimoxazole, gentamicin, meropenem and tetracycline by disc diffusion method....

Amphibians and reptiles from a highly diverse area of the Caatinga domain: composition and conservation implications
Provedor de dados: 49
Autores: Loebmann,Daniel; Haddad,Célio Fernando Baptista.
We surveyed the herpetofauna from the Complex of Planalto da Ibiapaba (CPI), CE, Brazil, during two years, using five sampling methods and information available in the literature. The amphibians are represented by 38 species distributed into nine families. The reptiles found summed 84 species, distributed into 25 families. Most amphibians collected exhibited wide occurrence along CPI, where we recorded 24 species (63.2%), which occurred at least in 60% of the sampled environments. Reptiles showed a different pattern, since 52 species (62.6%) had a restricted distribution (up to two environments). Sixteen species out of 25 considered as rare in CPI are restricted to relict moist forests. We also applied a rarity-vulnerability index to determine the most...

Amphibians and reptiles of the Parque Estadual Turístico do Alto Ribeira (PETAR), SP: an Atlantic Forest remnant of Southeastern Brazil
Provedor de dados: 49
Autores: Araujo,Cybele de Oliveira; Condez,Thais Helena; Bovo,Rafael Parelli; Centeno,Fernanda da Cruz; Luiz,Amom Mendes.
The herpetofauna of São Paulo State, Brazil, can be characterized as the most well-known in the country. However, despite the large number of studies in this area, there are still many sampling gaps within biomes such as the Atlantic Forest that are considered global conservation priorities due to the high rate of endemism and human disturbance. As a result of political and historical pressure, this biome has been reduced to less than 12% of its original extent and, despite its importance for global biodiversity conservation, only a small percentage of its original vegetation cover (1%) has some form of legal protection. This is the case of the Parque Estadual Turístico do Alto Ribeira (PETAR) which, together with the Parque Estadual de Intervales, Parque...

Ampliación de la distribución geográfica y temporal de Elochelys convenarum (Chelonii, Bothremydidae) en el Cretácico Superior de la Península Ibérica
Provedor de dados: 41
Autores: Pérez García,Adán; Ortega,Francisco; Murelaga,Xabier.
Durante el Campaniano y el Maastrichtiano, la fauna de tortugas de Europa Occidental estuvo fundamentalmente constituida por taxones endémicos. Los Bothremydidae, representados por los géneros Rosasia, Foxemys, Polysternon y Elochelys, son muy abundantes en este registro. Elochelys se conoce a partir de material relativamente escaso, compuesto únicamente por caparazones y placas aisladas, que fueron asignados a dos especies, Elochelys perfecta y Elochelys convenarum. En el registro francés, se ha atribuido a este género el caparazón que constituye el holotipo de Elochelys perfecta y la mitad anterior de otro, que se describe como el paratipo de la especie, del Campaniano de Fuveau, en Provenza. Además, el holotipo de Elochelys convenarum está constituido...

Autores: Sánchez-Rodríguez, D.C.; Acero-P., A.
The ariid Notarius grandicassis (Valenciennes, 1840), commonly known as Thomas sea catfish, occurs at northeastern South America, ranging between Colombia and Brasil. It was reported originally from the mouth of the Amazon to the Golfo de Venezuela. In 2002, it was reported from the Colombian Guajira peninsula. Herein, we report the species from the mouth of the Magdalena River (Bocas de Ceniza), where it is rather frequently obtained by fishermen.

&amp;#x2206;N-p63 functions as an invasion, migration, and metastasis suppressor
Provedor de dados: 17
Autores: Lakshmanane Boominathan.
The tumor suppressor p53 homologues, TA-p73, and p63 have been shown to function as tumor suppressors.  However, how they function as tumor suppressors remains elusive.  Expression of p63 is controlled by two distinct promoters.  Consequently, this results in two different gene products such as TA-(transactivation domain containing NH2 terminus) p63 and &amp;#x2206;N-(lacks NH2 terminus) p63.  It is generally thought that the TA-p63 functions as a tumor suppressor, while the &amp;#x2206;N-p73 functions as a proto-oncogene.  However, careful interpretation of the data concerning &amp;#x2206;N-p63 suggests that it could function as an invasion and metastasis/tumor suppressor in a cell context dependent manner.

An alternative early opening scenario for the Central Atlantic Ocean
Provedor de dados: 5
Autores: Labails, Cinthia; Olivet, Jean-louis; Aslanian, Daniel; Roest, Walter.
The opening of the Central Atlantic Ocean basin that separated North America from northwest Africa is well documented and assumed to have started during the Late Jurassic. However, the early evolution and the initial breakup history of Pangaea are still debated: most of the existing models are based on one or multiple ridge jumps at the Middle Jurassic leaving the oldest crust on the American side, between the East Coast Magnetic Anomaly (ECMA) and the Blake Spur Magnetic Anomaly (BSMA). According to these hypotheses, the BSMA represents the limit of the initial basin and the footprint subsequent to the ridge jump. Consequently, the evolution of the northwest African margin is widely different from the northeast American margin. However, this setting is in...

An altimetry-based gravest empirical mode south of Africa: 1. Development and validation
Provedor de dados: 5
Autores: Swart, Sebastiaan; Speich, Sabrina; Ansorge, Isabelle J.; Lutjeharms, Johann.
Hydrographic transects of the Antarctic Circumpolar Current (ACC) south of Africa are projected into baroclinic stream function space parameterized by pressure and dynamic height. This produces a two-dimensional gravest empirical mode (GEM) that captures more than 97% of the total density and temperature variance in the ACC domain. Weekly maps of absolute dynamic topography data, derived from satellite altimetry, are combined with the GEM to obtain a 16 year time series of temperature and salinity fields. The time series of thermohaline fields are compared with independent in situ observations. The residuals decrease sharply below the thermocline and through the entire water column the mean root-mean-square (RMS) error is 0.15 degrees C, 0.02, and 0.02 kg...

An altimetry-based gravest empirical mode south of Africa: 2. Dynamic nature of the Antarctic Circumpolar Current fronts
Provedor de dados: 5
Autores: Swart, Sebastiaan; Speich, Sabrina.
Swart et al. (2010) applied altimetry data to the gravest empirical mode south of Africa to yield a 16 year time series of temperature and salinity sections. In this study we use these thermohaline sections to derive weekly estimates of heat content (HC) and salt content (SC) at the GoodHope meridional transect of the Antarctic Circumpolar Current (ACC). These estimates compare favorably to observed data. The resulting 16 year time series of HC and SC estimates are used to explain the subsurface thermohaline variability at each ACC front and frontal zone. The variability at the Subantarctic Zone (SAZ) is principally driven by the presence of Agulhas Rings, which occur in this region approximately 2.7 times per annum and are responsible for the longest and...

In this paper, we investigate substitution/complementarity relationships among products sold with different bundled characteristics and under different vertical arrangements. Our conceptual model demonstrates the interactive price impacts emanating from product differentiation, market concentration and market size. The model is applied to the U.S. cottonseed market using transaction level data from 2002 to 2007. This market has been impacted structurally in numerous ways due to the advances and the rapid adoption of seeds with differing bundles of biotechnology traits and vertical penetration emanating from the biotechnology seed industry. Several interesting findings are reported. The econometric investigation finds evidence of sub-additive pricing in the...

An Analysis of Bundle Pricing: The Case of the Corn Seed Market
Provedor de dados: 31
Autores: Shi,   Guanming; Chavas,   Jean-Paul; Stiegert,   Kyle W.
This paper investigates bundle pricing under imperfect competition. In a multiproduct context, we first examine how substitution/complementarity relationships among products can affect pricing. This is used to motivate multi-product generalizations of the Herfindahl-Hirschmann index (GHHI) capturing cross-market effects of imperfect competition on bundle pricing. The GHHI model is applied to pricing of conventional and patented biotech seeds in the US from 2000-2007. One major finding is that standard component pricing in biotech traits is soundly rejected in favor of sub-additive bundle pricing. This result is consistent with the presence of scope economies in the production of genetic traits. The econometric estimates show how changes in market...

Integration of the Chilean domestic economy into international markets has created the need to incorporate more technology, information, and management tools and to generate better entrepreneurial skills at the farm level. These changes require the development of strategic capabilities and farmer changes in attitude. The goal for farmers is to be more prepared for the decision-making process and to have adequate evaluation and control systems to face the complexity of the farm business. The literature suggests that using management tools positively correlates with profits and concludes that management skills are positively related to farmers' well-being.

An analysis of farmers’ behaviour and rewarded provision of public goods
Provedor de dados: 31
Autores: Roel,   Jongeneel; Ge,   Lan.
Aiming to stimulate the role of agriculture as provider of public goods, the new CAP reform raises many theoretical and practical questions. The most relevant ones concern farmers’ response to the policy instruments. This paper uses a formal model to analyse the incentives and constraints generated by policy instruments and their potential impact on farmers’ participation decision. The analysis shows that, when choosing policy instruments to stimulate provision of public good, it is important to take into account different degrees and mechanisms of jointness between commodity and non-commodity (potentially public good) production, as they can enhance or erode the desired effect of the policy instruments. Some implications for modelling and policy analysis...

The impacts of economic and demographic variables on the demand for food grain commodities in urban Jiangsu province of China are estimated, using both the QUAIDS and the AIDS models. Results show that the demands for wheat flour and coarse grains are price-elastic while the demands for rice and grain products are price-inelastic. Certain demographic variables show as having a significant impact on food grain demand. Finally, a decomposition of causes of changes in rice consumption over the period of 1995–2007 is performed.

Results suggest that farmers who (1) intend to leave their farm to children; (2) have not inherited their farm from previous generation; (3) perceive a lower impact of milk quota abolition on business; (4) have less negative attitudes towards policies/regulations; and (5) perceived a lower influence of policies/markets on business during the past decade are most likely to increase farm size.

An Analysis of Rural Livelihood Systems in Rainfed Rice-based Farming Systems of Coastal Orissa
Provedor de dados: 31
Autores: Samal,   Parshuram; Barah,   B.C.; Pandey,   Sushil.
The livelihood systems of farm households in coastal Orissa have been analysed based on a sample of 193 farmers. It is found that the incomes of these households were quite diversified. As against the general impression that crop income dominates household income, it is observed that the non-farm income has emerged important in the coastal Orissa. Rice, which has been traditionally the main source of income in this area, has slipped to the third position, next to remittances and income from non-farm activities. The income from non-farm works and rice has accounted for 71 per cent and 20 per cent of the total income, respectively. The non-farm sources have contributed more than 90 per cent towards income inequality. The source-wise income share has also...

An Analysis of the 2002 Farm Bill’s Value-Added Producer Grants Program
Provedor de dados: 31
Autores: Boland,   Michael A.; Crespi,   John M.; Oswald,   Dustin.
Our objective is to identify the determinants for success among USDA’s Value- Added Producer Grants (VAPG) program recipients. Business development has become an important program in departments of agricultural economics. Market share was found to be an important determinant of VAPG success. Size variables including greater sales and increased grant dollars, as well as a lower number of producers, were also determinants of business success. Departments of agricultural economics are likely best able to assist VAPG recipients by providing information on price discovery, explaining their relationship to potential plant location, and providing education on best management practices to help producers avoid costly mistakes.

An analysis of the determinants of flood damages
Provedor de dados: 31
Autores: Ferreira,   Susana.
In this paper we analyze mortality caused by 2,194 large flood events between 1985 and 2008 in 108 countries. Unlike previous studies that looked at natural-disaster mortality, we find that year-to-year changes in income and institutional determinants of vulnerability do not affect flood mortality directly. Income and institutions influence mortality only indirectly, through their impact on the intensity and frequency of floods. Population exposure affects the number of deaths both directly and indirectly. Higher population exposure results in more deaths once the flood has occurred, but it is associated with smaller floods. In developing countries it also reduces the count of floods.

This study examines factors that affect the participation behavior of limited resource farmers in agricultural cost-share programs in Alabama.  The data were generated from a survey administered to a sample of limited resource farm operators.  A binary logit model was employed to analyze the data.  Results indicate that college education, age, gross sales, ratio of owned acres to total acres, and rented acres, as well as membership in a conservation association, had significant influence on cost-share program participation.

Autores: Katchova,   Ani L.
This study examines the financial performance and stress experienced by beginning farmers in the U.S.  Using the USDA’s ARMS data, probit models are estimated to study the personal and farm characteristics that affect whether or not the financial ratios fall into critical zones.  The results show that older farmers and larger farms are less likely to experience financial stress while hobby farms and livestock farms are more likely to experience financial stress.  The results for beginning farmers indicate fewer significant effects.  These findings point out the characteristics that agricultural lenders need to consider when evaluating farmers’ loans.

An analysis of the Peruvian jungle cocoa farmers: Acopagro cooperative vs. intermediaries – a case of study
Provedor de dados: 31
Autores: Higuchi,   Angie; Moritaka,   Masahiro; Fukuda,   Susumu.
n the Peruvian jungle, there are two main cocoa marketing channels: the intermediaries and the cooperative. The Acopagro Cooperative, a Peruvian organization, for example, has contributed to the shift from illegal crops like cocoa to an alternative crop like cocoa which gives small scale farmers a sustainable welfare. A survey of 243 farmers in Juanjui, San Martin-which is the main cocoa production area in Peru-was carried out between December 2009-January 2010. This study analyzes Peruvian cocoa farmers’ socio-economic characteristics as these attributes affect their decision-making process in the cocoa commercialization for their self-improvement and evaluates if the farmers’ participation in Acopagro or not influences the increment of the cocoa...

An Analysis of the Pricing of Traits in the U.S. Corn Seed Market
Provedor de dados: 31
Autores: Shi,   Guanming; Chavas,   Jean-Paul; Stiegert,   Kyle W.
This paper investigates the pricing of patented traits in the U.S. hybrid corn seed market under imperfect competition. In a multiproduct context, we first examine how substitution/complementarity relationships among products can affect pricing. This is used to motivate multi-product generalizations of the Herfindahl-Hirschman index (GHHI) capturing cross-market effects of imperfect competition on bundle pricing. The GHHI model is applied to pricing of conventional and patented biotech seeds in the US from 2000-2007. One major finding is that standard component pricing in biotech traits is soundly rejected in favor of subadditive bundle pricing. The econometric estimates show how changes in market structures (as measured by both own- and cross-Herfindahl...

AN ANALYSIS OF THE RETIREMENT-CONSUMPTION PUZZLE FOR FOOD-AT-HOME AND AWAY-FROM-HOME EXPENDITURES IN GERMANY
Provedor de dados: 31
Autores: Drescher,   Larissa S.; Roosen,   Jutta.
According to Ando and Modigliani (1957), consumers pass different stages of a lifecycle with different impact on demand. The criticism that the life-cycle theory neglects generational effects and concentrates on ageing effects only has led to the application of the cohort analysis which decomposes not only age, but also period and cohort effects. Following these ideas, this paper presents results of a cohort analysis on food-at-home and away-from-home consumption covering 25 years of German consumption data. Special attention is given to the retirement-consumption puzzle which is the unanticipated drop in consumption after retirement. Results of seemingly unrelated regressions indicate that there are significant age, period and cohort effects of...

An analytical framework for incorporating land use change and forestry in a dynamic CGE model
Provedor de dados: 31
Autores: Pant,   Hom M.
Forestry poses a challenge to computable general equilibrium (CGE) modellers working with recursively dynamic models. This is because of the lag between its inputs and output, which do not correspond to the same time period as other sectors. Inputs are applied for a number of years before a forest is ready for harvest. As a result, attempts in the past to incorporate a well-specified forestry sector in a recursive CGE model have been only partly successful. The purpose of this paper is to fill this gap by presenting a consistent analytical framework which can be used to incorporate forestry into a recursively dynamic global CGE model. A key feature of the framework is that it splits the forestry activity into three parts—planting, holding and harvesting....

Although Cuba is the most studied Caribbean island with regard to freshwater Cladocera, our knowledge of their species composition and distribution is still limited. In this study, all available published and unpublished, reliable sources were reviewed for all records of this group of crustaceans. Thus, a revised and updated list of 70 species of the orders Ctenopoda and Anomopoda recorded for the island is here presented, including all sources of information. From the total number of records, about 32% are doubtful. Comments on these and on other selected species are included. From a biogeographical point of view, the fauna of Cuba is closely related to that of southern Mexico, and both regions have a close similarity with South America. The actual...

An annotated list of ornamentals naturally found infected by Brevipalpus mite-transmitted viruses
Provedor de dados: 63
Autores: Kitajima,Elliot Watanabe; Rodrigues,José Carlos Verle; Freitas-Astua,Juliana.
The first cases of ornamental plants found infected by Brevipalpus transmitted viruses (BTV) were described in the 1990's from the region of Piracicaba, State of São Paulo, Brazil; subsequent cases were from other regions in the country and other American countries. Currently, 37 ornamental plant species (for the sake of simplicity, orchids being considered as a single species), belonging to 18 families of dicotyledons, have been reported hosting BTV. Because of the non systemic type of infection of these viruses, the localized diseases they cause are unimportant usually, but they have the potential to cause economic losses if severe outbreaks of Brevipalpus mite populations occur. Some ornamentals may serve as reservoirs to BTV known to cause serious...

Formation and differentiation of salt crystal is a most common as well as challenging problem during protein crystallography. Although there are some methods used for their differentiation i.e. physical manipulation, birefringence, dye absorption and run a gel but all of them are totally depends on own perception and expertise as well as also require a good crystal (final stage crystal). To escape this problem the screening was done with PACT, JCSG and other automated screens as everyone do. But during optimization the additives/salts were ignored at first and optimization screen was made just based on different buffers and precipitant. After selecting suitable buffer, the type and percentage of precipitant was optimized. We got some ugly crystals and with...

It cannot be said that aquaculture has ignored sustainable development (SD), judging by the number of standards, guides and indicators devoted to it, produced mainly under the aegis of international organizations such as FAO, The European Union and sorne NGOs. However, these continue to be perceived in large measure as constraints rather than as shared objectives by actors. Faced with this situation, which is not specific to aquaculture but on the contrary quite general regardless of sector, context or scale, the authors seek to propose a generic approach that through a collective process, i.e. a co-construction, promotes the implementation and appropriation of SD. What makes this approach original is not only the participatory nature of the construction,...

An approach to the study of the fungal deterioration of a classical art material: Mastic varnish
Provedor de dados: 69
Autores: Romero-Noguera,Julio; López-Miras,María del Mar; Martín-Sánchez,Inés; Ramos-López,José Miguel; Bolívar-Galiano,Fernando.
Mastic, one of the best natural varnishes, is frequently used as protective and finishing layer or as component of oleo-resinous media in paintings, both in the past and currently. However, this resin is affected by complex deterioration processes which can change its characteristics and thus the visual aspect of works of art. The alteration processes caused by radiation have been widely studied, but there is a lack of information on the biodeterioration of this natural product. In this paper, fungi from collections as well as from oil paintings of the Fine Arts Museum of Granada (Spain) were inoculated onto slides covered with mastic. The samples, after an incubation period of 15 days, were analysed by gas chromatography-mass spectrometry (GC-MS) to...

An Assessment of Dynamic Behavior in the U.S. Catfish Market: An Application of the Generalized Dynamic Rotterdam Model
Provedor de dados: 31
Autores: Muhammad,   Andrew; Jones,   Keithly G.
The generalized dynamic Rotterdam model was used in estimating U.S. demand for disaggregated catfish. The overall goal was to examine habit persistence in consumption and to determine the adjustment process in demand. Results indicated that it took up to 1 month for catfish-product demand to fully adjust to changes in expenditures and prices. Additionally, habit persistence played a role in demand where present consumption of a given product was positively affected by past consumption of that product. Consequently, U.S. catfish demand was significantly more elastic in the long-run.

An assessment of farmer’s risk exposures and policy impacts on farmer’s risk management strategy
Provedor de dados: 31
Autores: Anton,   Jesus; Kimura,   Shingo.
This paper describes farmer’s exposures to risks at the individual farm level and develops a model representing the decisions of an individual risk averse farmer facing variability in both prices and yields. A set of stylised risk market instruments is represented. The model is calibrated using farm level data from Germany. Monte-Carlo simulations of the random variables are run, and the corresponding optimal responses are obtained. The main focus of this paper is the interactions between government payments and the farmers’ use of risk market instruments in terms of the potential crowding out of such instruments and impacts on farm return and welfare. Unlike other studies this paper models farming response to payments in terms of production and the use of...

Autores: Capps,   Oral, Jr.; Williams,   Gary W.
This report examines the likely effects of additional agricultural water rights under the Columbia River Initiative (CRI) on net crop revenues (hay, orchards, vegetables, potatoes, wheat, and other crops) in the state of Washington over the next 20 years. This study corrects for four potentially serious methodological flaws made in two previous studies associated with the CRI and concludes that those studies substantially overestimated the net revenues accruing to producers in the Columbia River area from new irrigated acreage under the CRI. In fact, the net revenues are more likely to be negative than positive. Methodological errors made in the two previous studies lead to results that support a policy prescription that is just the opposite of what would...

An Assessment of U.S. Market Access for Traditional and Nontraditional Agricultural Exports Under the  Caribbean Basin Initiative
Provedor de dados: 31
Autores: Ames,   Glenn C.W.
The Caribbean Basin Economic Recovery Act (CBERA) provides duty-free access for Caribbean and Central American products entering U.S. markets. This paper compares the performance of traditional agricultural exports (beef, bananas, coffee, sugar and tobacco products) and nontraditional exports (pineapples, melons, fresh citrus, frozen orange juice and vegetables) under the CBERA. The decline in the value of traditional agricultural exports exceeded the gains in nontraditional exports by 400 percent. Tariffs and a limited range of duty-free goods still constrain CBERA’s development potential despite gains under the amended legislation.

Volume-ratio and total volume models for Eucalyptus nitens and E. globulus grown in southern Chile were ftted independently. The validation process considered the bias and the total error in the volume estimates, as well as the age classes close to thinning and harvesting operations. Volume estimates from the system of functions (volume and ratio) were compared to the volume estimates from a taper function (Bruce model) to estimate the volume at different top stem diameters. The results indicated that general (as opposed to local) logarithmic functions performed better in their estimation of the total volume for both species, while a unique polynomial model was the best model for the ratio estimates for both Eucalyptus species.

An Atlantic Canada Perspective on Social Audit: Why do Cooperatives Embrace the Theory but not the Practice?
Provedor de dados: 31
Autores: MacLean,   Maureen; MacKinnon,   Brenda.
This paper considers the implications for a cooperative which does not undertake to complete a social audit even though it embraces the theory. We show that some cooperatives have commenced work but have failed to complete the audit or failed to implement audit recommendations. We show that for the most part cooperatives have not recognized the cooperative advantage that undertaking a social audit provides. We analyze the reasons that are given and find that financial and time constraints, the fact that few models exist here in Atlantic Canada, lack of a well-defined methodology and a lack of commitment by management and volunteers, combine to present barriers to completing the process. We compare a cooperative and a credit union which have been directed...

Even if, a large number of laboratories around the world and India make crystals of protein but majority of them fail to generate crystallographic data less than or equal to 10A resolution with currently available instruments. This means that X-ray crystallographic data have been generated from protein crystals with non-uniform lattices. We believe that a large portion of (chain of...

An ecological and comparative analysis of parasites in juvenile Mugil liza (Pisces, Mugilidae) from two sites in Samborombón bay, Argentina
Provedor de dados: 76
Autores: Montes,Martin M.; Martorelli,Sergio R.
ABSTRACT Mugil liza Valenciennes, 1836 is an economically important food fish and has been recommended for aquaculture in South America. A total of 278 fishes were collected in the spring and summer of 2009 and 2010. These fish were sorted into sample groups according to their size class. We used Bayesian statistics and 95% credible intervals for each parameter tested were calculated. Fish studied harbored a total of 15 different species of parasites. Diversity of parasite species found on Mugil liza was greatest at the S.R.C. collection site, but evidenced a lower species richness than at A.R. site. The 1st size fishes of both sites evidenced greater parasite diversity than either 2nd or 3rd size fish. Differences observed could be explained by the...

Autores: Chinnappa,   B.
The economic feasibility of land reclamation technologies adopted by the farmers of Tungbhadra Command Area in Karnatka for amelioraion of irrigation-induced soil degradation has been studied. The data have been analysed using tabular method and partial budgeting method. It has been found that the available technologies are not being spread effectively among the affected farm households. Amongst different technologies followed by the farmers, adoption of leaching has been found least costly and could result in an incremental output of 14 quintals per hectare on saline soils of both head- and mid-regions. Green manuring has been observed to be another effective technology and could enhance crop yields on saline as well as waterlogged soils. Partial...

An Economic Analysis of Modern Rice Production Technology and its Adoption Behaviour in Tamil Nadu
Provedor de dados: 31
Autores: Devi,   K. Sita; Ponnarasi,   T.
Rice is the staple food in Tamil Nadu and is grown in an area of 2.6 Mha with a production of 8.19 Mt and productivity of 3.2 t/ha. In the context of high water demand by rice farmers, any strategy that would produce higher rice yield with less water is the need of the day. One such system is “System of Rice Intensification” (SRI), which was developed by Fr. Henri de Laulanie in Madagascar in 1980. The general objective of the study is to find the economics and the farmer’s adoption behaviour of the system of rice intensification. The study has revealed that the per hectare cost of cultivation is about 10 per cent lower in SRI than the conventional method. The logit framework has indicated that age, farm size, income of the farm, number of earners in the...

An Economic Analysis of No-Till Rotations and Effects on Carbon Sequestration and Long Term Sustainability of Agriculture
Provedor de dados: 31
Autores: Janssen,   Larry; Harer,   Justin.
This study summarizes key economic results from 100 different no-till (NT) crop rotations and a conventional (CT) corn-soybean rotation based on agronomic data from Brookings County, South Dakota for 2001 -2008. A 1200 acre model crop farm was constructed to conduct the farm management budget and simulation analyses. Results indicate: (1) the CT rotation had the highest average net returns, (2) Several four-crop no-till rotations were preferred as producer risk aversion increased, and (3) carbon credit payments would need to be $14 to $36 per acre for the top four NT rotations to be as profitable as the CT rotation.

Autores: Tarrant,   Katherine A.; Armstrong,   Dan P.; Ho,   Christie K.M.; Wales,   W.J.; Malcolm,   Bill.
A range of options for utilising additional land on a dairy farm in the high rainfall area of Gippsland were analysed. The aim was to determine if additional land may assist the owners/operators in maintaining or increasing profit in the medium term (5-10 years). Historical trends have been towards fewer, larger, more intensive enterprises, and this project studies the value of additional land in continuing or altering this trend. A case study farm and spreadsheet modelling approach was used to examine these issues. Five different uses for additional land were identified by an expert steering committee, and were compared to the base farm system over a 10-year development period. The results suggest that expanding the milking area by purchasing additional...

Autores: Jacquet,   Florence; Butault,   Jean-Pierre; Guichard,   Laurence.
The paper aims to study the effects of reducing pesticide use by farmers in the arable sector in France and the feasibility of a policy target of reducing pesticide use by half. The originality of the approach is to combine statistical data and expert knowledge to describe low-input alternative techniques at the national level. These data are used in a mathematical programming model to simulate the effect on land use, production and farmers’ income of achieving different levels of pesticide reduction. The results show that reducing pesticide use by 30% could be possible without reducing farmers’ income. We also estimate the levels of tax on pesticides necessary to achieve different levels of reduction of pesticide use and the effect of an incentive...

An Economic Assessment of the Impacts of the MOSE Barriers on Venice Port Activities
Provedor de dados: 31
Autores: Vergano,   Lucia; Umgiesser,   Georg; Nunes,   Paulo A.L.D.
Due to its hydro-geological features, the lagoon of Venice is especially vulnerable to climate change. In particular, it is strongly affected by gradual global warming that brings about the so-called ‘acqua alta’ (high water) phenomenon with greater frequency and intensity. In order to protect the city of Venice from the more and more frequent phenomenon of flooding, some protective measures have been adopted. Among them, the system of mobile barriers commonly known as MOSE: however, by separating the lagoon from the Adriatic Sea, it interferes with ship traffic and has negative impacts on port activities. Against this background, the aim of the present work is to provide an estimate of the direct costs of ship traffic interruption due to the functioning...

An Economic Evaluation of Soybean-Based Biodiesel Production on Commercial Farms in the Soybean-Producing Regions of KwaZulu-Natal: Some Preliminary Results
Provedor de dados: 31
Autores: Sparks,   G.D.; Ortmann,   Gerald F.; Lagrange,   L.
Global biofuel production has risen substantially in recent years, driven primarily by government support for biofuel industries. The stated motivations for these initiatives are numerous and have varied over time. Soybeans are the only field crop produced in sufficient quantities in KwaZulu-Natal (KZN) that the South African (SA) industrial biofuel strategy identifies as a potential biodiesel feedstock. Preliminary results from a mixed integer linear programming model support the notion of Funke et al. (2009), who contend that the incentives and commitments outlined by the industrial biofuel strategy are inadequate to both establish and sustain a domestic biodiesel industry.

An economic evaluation of the osmoregulation gene technology to the Australian wheat industry
Provedor de dados: 31
Autores: Farquharson,   Robert J.; Morgan,   J.M.; Brennan,   John P.
Episodes of rainfall irregularity and soil moisture deficit have focused attention on the widespread limitation of water supply on winter cereal crop production in Australia. This has motivated a number of efforts at breeding for improved drought tolerance. A recent example involves a cellular adaptation which mitigates water loss through solute accumulation (osmoregulation or osmotic adjustment). An assessment of the performance of osmoregulation yield response in the presence of climate change found that wheat cultivars with this gene are unlikely to be adversely affected by hotter and drier conditions across the wheat belt. The results of an economic evaluation of potential future innovations (wheat cultivars) from the osmoregulation gene technology are...

An economic evaluation of tick line deregulation in Queensland
Provedor de dados: 31
Autores: Chudleigh,   Fred; Franco-Dixon,   Mary Ann.
Rhipicephalus microplus, the cattle tick, is widely distributed across many tropical and subtropical regions of the world and has been identified as the most economically important species of tick across a number of countries. Quarantine boundaries currently limit the spread of the cattle tick into northern New South Wales, parts of South East Queensland, the central parts of the Northern Territory and northern parts of Western Australia. The Queensland tick line (or quarantine boundary) largely follows the 500mm rainfall isohyet until it reaches southern Queensland. As the cattle tick is unlikely to become endemic to regions receiving median rainfall less than 500mm per annum, the region most likely to be effected by a deregulation of the tick line is...

An Economic Framework for Forecasting Land-Use and Ecosystem Change
Provedor de dados: 31
Autores: Lewis,   David J.
This paper develops a joint econometric-simulation framework to forecast detailed empirical distributions of the spatial pattern of land-use and ecosystem change. In-sample and out-of-sample forecasting tests are used to examine the performance of the parcel-scale econometric and simulation models, and the importance of multiple forecasting challenges is assessed. The econometric-simulation method is integrated with an ecological model to generate forecasts of the probability of localized extinctions of an amphibian species. The paper demonstrates the potential of integrating economic and ecological models to generate ecological forecasts in the presence of alternative market conditions and land-use policy constraints.

This study evaluates both the profitability and risk efficiency of grazing stocker steers on conservation tillage winter wheat pasture using simulation and stochastic efficiency with respect to a function (SERF). Average daily gains are simulated for steers grazed on conventional tillage (CT), reduced tillage (RT) and no-till (NT) winter wheat pasture.  Steer price distributions and prices for key production inputs such as diesel, fertilizer, and glyphosate are also simulated. Stocker steer net return distributions by tillage treatment are constructed and ranked for risk efficiency using SERF.  The results indicate the NT system is the most profitable and most risk efficient of the three tillage systems, followed by the RT system. Both conservation tillage...

An Economic Risk Analysis of Tillage and Cropping Systems on the Arkansas Grand Prairie
Provedor de dados: 31
Autores: Hignight,   Jeffrey A.; Watkins,   K. Bradley; Anders,   Merle M.
No-till (NT) has been shown to reduce fuel, labor, and machinery costs compared to conventional-till (CT) but very few rice producers in Arkansas practice NT.  The low adoption rate is most likely due to difficulties in management but also limited information on the profitability and risk of NT.  Most rice producers are knowledgeable on NT costs savings but consider it less profitable due to yield reductions offsetting costs savings.  This study evaluates production costs, crop yields, and economic risk of both NT and CT in five rice-based cropping systems (continuous rice, rice-soybean, rice-corn, rice-wheat, and rice-wheat-soybean-wheat).  Yields, crop prices, and key input prices are simulated to create net return distributions.  Stochastic efficiency...

Autores: Sadia¹,B; Josekutty,PC; Potlakayala,SD; Patel,P; Goldman,S; Rudrabhatla,SV.
A robust protocol for culturing meristems of Sorghum is required to assist with rapid genetic improvement of the genus. Through meristem culture, an efficient method for rapid micropropagation was developed for Sorghum bicolor (L.) Moench. hybrids, namely NC+262, NC+6C21 and NC+6B50. Complete plants were regenerated directly from shoot meristems without an intervening callus phase. Regeneration frequencies varied between the studied genotypes and according to the growth regulator combinations present in the medium. The combination of BAP and TDZ showed a synergistic effect on shoot multiplication. The highest number of shoots per meristem (68 ± 2) was recorded for the genotype NC+262, followed by NC+6C21 (31.3 ± 0.8), and NC+6B50 (16 ± 1.7). MS medium...

Autores: Hoe,   Lam Weng; Saiful Hafizah,   Jaaman; Zaidi,   Isa.
Risk is one of the important parameters in portfolio optimization problem. Since the introduction of the mean-variance model, variance has become the most common risk measure used by practitioners and researchers in portfolio optimization. However, the mean-variance model relies strictly on the assumptions that assets returns are multivariate normally distributed or investors have a quadratic utility function. Many studies have proposed different risk measures to overcome the drawbacks of variance. The purpose of this paper is to discuss and compare the portfolio compositions and performances of four different portfolio optimization models employing different risk measures, specifically the variance, absolute deviation, minimax and semi-variance.

An empirical examination of import demand for pulses in India
Provedor de dados: 31
Autores: Agbola,   Frank W.; Damoense,   Maylene Y.
India is the largest producer and importer of pulses in the world. Since 1970, the Indian food economy has undergone major policy reforms, including trade liberalisation, that had the effect of opening up its domestic pulse market to international trade. This market is very lucrative and of major significance to the world pulse economy. Therefore, given the increasing evidence linking import demand and economic variables, an understanding of the impact of these variables on import demand for pulses in India is warranted. The import demand functions for total pulses, chickpea and lentils were estimated by autocorrelation regression procedure using time-series data for the period 1970 through to 2000. Empirical results indicate that real GDP, population,...

This paper investigates empirically the factors that influence real agricultural wage rates in Ghana, based on 1957 to 1991 data. The Johansen cointegration framework is used to examine long-run relationships among agricultural and urban wage rates, the domestic terms of trade between agriculture and nonagriculture, urban unemployment, capital stock in agriculture and the size of the rural population. An error correction model is then used to investigate short-run dynamic relationships among the variables. The results show that: (1) there is only one stable equilibrium relationship among agricultural wage rates and their determinants in the long-run; (2) a 1 percent change in the domestic terms of trade between agriculture and non-agriculture leads to a...

The paper investigates the capitalizations of aggregate and disaggregate government subsidies into farmland rental rates using selection bias correction models. It investigates cash as well as share rental rates, which are largely used in US agriculture. The empirical results suggest that government subsidies have large significant effects on rental rates. More specifically, we find that landlords capture 37%-38% of the aggregate subsidies under cash leases, and 86%-88% under share contracts. Disaggregate farm programs are also found to have different impacts on rental rates according to the types of programs and leasing arrangements.

With rapid population growth, securing the inherent vulnerability of this relationship, whether social, economic, or environmental, has to be central to efforts to achieving sustainable development. The vulnerability of agricultural systems varies with geographic location, time, socioeconomic conditions, and environmental resources. The capacity to mitigate and to adapt to climate-change impacts is strongly related to the future development paths. The socioeconomic and, even more so, the technological characteristics of different futures strongly affect emissions, hence the extent and pace of the impacts of climate change, as well as the capability...

An ERA40-based atmospheric forcing for global ocean circulation models
Provedor de dados: 5
Autores: Brodeau, Laurent; Barnier, Bernard; Treguier, Anne-marie; Penduff, Thierry; Gulev, Sergei.
We develop, calibrate and test a dataset intended to drive global ocean hindcasts simulations of the last five decades. This dataset provides surface meteorological variables needed to estimate air-sea fluxes and is built from 6-hourly surface atmospheric state variables of ERA40. We first compare the raw fields of ERA40 to the CORE.v1 clataset of Large and Yeager (2004). used here as a reference, and discuss our choice to use daily radiative fluxes and monthly precipitation products extracted from satellite data rather than their ERA40 counterparts. Both datasets lead to excessively high global imbalances of heat and freshwater fluxes when tested with a prescribed climatological sea surface temperature. After identifying unrealistic time discontinuities...

An Ethanol Blend Wall Shift is Prone to Increase Petroleum Gasoline Demand
Provedor de dados: 31
Autores: Qiu,   Cheng; Colson,   Gregory; Zhang,   Zibin; Wetzstein,   Michael E.
The US Environmental Protection Agency announced a waiver allowing an increase in the Fuel-Ethanol blend limit (the “blend wall” ) from 10% (E10) to 15% (E15) on October,2010.Justifications for the waiver are reduced vehicle fuel prices and less consumption of petroleum gasoline, leading to energy security. In this paper, employing Monte Carlo simulations and Savitzky-Golay smoothing filter, an empirical study examines this waiver revealing an anomaly where a relaxation of this blend wall elicits a demand response. Under a wide range of elasticities, this demand response can actually increase the consumption of petroleum gasoline and thus lead to greater energy insecurity. The economics supporting this result and associated policy implications are...

An ethanol-based process to simultaneously extract and fractionate carotenoids from Mauritia flexuosa L. Pulp
Provedor de dados: 94
Autores: Ribeiro,Bernardo Dias; Nascimento,Rafaella Ferreira; Barreto,Daniel Weingart; Coelho,Maria Alice Zarur; Freitas,Suely Pereira.
Mauritia vinifera (buriti) is a palm tree that grows wild in different areas of Brazil, particularly in the Amazonian region. The buriti oil is rich in carotenoids, especially in β-carotene. The growing interest in other natural sources of β-carotene has stimulated the industrial use of buriti as a raw material for pulp oil extraction. Most processes are based on the conventional technologies, involving drying and pressing the pulp for oil recovery and further separation of carotenoids in a liquid phase using organics solvents. In the present work, the ethanol-based process was evaluated for simultaneous carotenoids recovering and fractionating from buriti pulp. The raw material and ethanol, 1:4 ratio, were placed in an erlenmeyer flask and maintained at...

An EU-Canada bilateral trade agreement: A DefraTAP application
Provedor de dados: 31
Autores: Kitou,   Elisavet; Philippidis,   George.
The first round of negotiations held in Ottawa on the 19th October, 2009, heralded the opening of bilateral trade talks intent on reaching a Canadian-European Union (EU27) free trade area (FTA) agreement. A second round of negotiations were staged in Brussels in January, whilst further rounds are scheduled for 2010, with the longer term aim of ratifying an agreement within 24-30 months. Although stumbling blocs will be encountered, the divergent political interests of each region are compatible. In Canada, a FTA with its second largest trading partner offers a viable alternative to its current overdependence on the US. Similarly, the EU27 sees an opportunity to regain a competitive foothold in the North American market. This paper re-examines the long run...

Autores: Loyd, Kerrie Anne T.; University of Georgia; kloyd@uga.edu; DeVore, Jayna L.; University of Georgia; jdevore@uga.edu.
The feral domestic cat (Felis catus) is a predatory invasive species with documented negative effects on native wildlife.  The issue of appropriate and acceptable feral cat management is a matter of contentious debate in cities and states across the United States due to concerns for wildlife conservation, cat welfare, and public health. Common management strategies include: Trap-Neuter-Release, Trap-Neuter-Release with removal of kittens for adoption and Trap-Euthanize. Very little empirical evidence exists relevant to the efficacy of alternative options and a model-based approach is needed to predict population response and extend calculations to impact on wildlife. We have created a structured decision support model representing multiple stakeholder...

Autores: Bernow, Stephen; Tellus Institute; sbernow@tellus.org; Duckworth, Max; Tellus Institute; maxd@tellus.org.
This paper presents and discusses an integrated set of policies designed to reduce U.S. carbon emissions over the next four decades.  This innovation path also aims to promote environmental quality, particularly by reducing emissions of criteria air pollutants, to reduce U.S. dependence on imported oil, and to induce technological innovation and diffusion in energy production and consumption. The innovation path would reduce economy-wide carbon emissions by 26% below baseline projections for 2010 and by 62% below baseline projections for 2030; this translates into 10% below 1990 levels in 2010 and 45% below 1990 levels in 2030.  Emissions of criteria pollutants also would be significantly reduced, as would petroleum imports by the United States. Moreover,...

An Evaluation of Purebred Bull Pricing: Implications for Beef Herd Management
Provedor de dados: 31
Autores: Atkinson,   Rebecca; Sanders,   Dwight R.; Jones,   Karen; Altman,   Ira J.
The selection of herd bulls is important in determining profitability of commercial ranchers and cow-calf operators as well as purebred producers. In this research, the key attributes of bulls – based on visual, performance, and ultrasound data – are valued using a traditional hedonic pricing model. The data are collected from the annual bull test trial and sale at Southern Illinois University Carbondale. The results suggest that buyers at the SIUC Beef Evaluation Station are willing to pay more for bull characteristics associated with calving ease and weaning weights. For instance bulls with a combination of both lower birth weight Expected Progeny Differences (EPDs) and high yearling weight EPDs than average can command premiums of over $1,150 per head...

An Evaluation of Tennessee Soybean Growers’ Views on a New Generation Cooperative to Produce Biodiesel
Provedor de dados: 31
Autores: Jensen,   Kimberly L.; English,   Burton C.; Menard,   R. Jamey; Zhang,   Yu.
Substituting petroleum diesel with biodiesel could decrease air emissions, reduce reliance on foreign oil, and help expand markets for U.S. farmers. Soybean producers can potentially capture this value-added by forward integrating the processing of soybeans into biodiesel via a New Generation Cooperative (NGC). Using probit analysis, this study examines factors influencing soybean producers’ willingness to participate in an NGC to produce biodiesel. Tobit analysis is used to examine the factors influencing the number of shares the soybean producer would be willing to purchase. Survey results indicate that over 70% of the soybean producers in the study group are interested in investing in an NGC to produce biodiesel. Among those producers willing to...

Autores: Belasco,   Eric J.; Ghosh,   Sujit K.; Chidmi,   Benaissa.
This research extends past work by Shonkwiler and Yen (1999) by allowing for distributional flexibility and nonlinear responses in the form of established semiparametric and nonparametric regressions. The proposed models are shown to outperform the parametric version typically used in demand analysis to characterize a system of censored equations in terms of model fit and prediction power. Using the developed models, we derive elasticities associated with different individual-specific scenarios with regard to the recently proposed “penny-an-ounce” tax on soft drinks sweetened with sugar.

Autores: Alston,   Julian M.; Hyde,   Jeffrey; Marra,   Michele C.; Mitchell,   Paul D.
This study examined the potential economic impacts in the United States of the commercial adoption of a corn rootworm (CRW) resistant transgenic corn. Using a counterfactual approach, we estimated that if the technology had been made available in the year 2000 at a price that would equate per acre costs to those for insecticide-based corn rootworm control, and adopted on all of the acres treated for corn rootworm in that year, the total benefits would have been $460 million. This benefit includes $171 million to the technology developer and seed companies, $231 million to farmers from yield gains, and a further $58 million to farmers from reduced risk, time savings, and other nonpecuniary benefits associated with reduced use of insecticides.

Autores: Galbraith,   Craig.
This paper utilizes an error correction model to examine how anhydrous ammonia (AA) and urea prices at different locations in North America adjusted to changes in crop and input prices during two time periods: 2002 to 2005 and 2006 to 2009. The empirical results suggest that natural gas futures prices had relatively more of an impact on nitrogen fertilizer prices during the 2002-2005 period. Nitrogen prices tended to adjust more rapidly to increases in natural gas futures prices than decreases. In the 2006 to 2009 period, corn futures prices had more of an impact on nitrogen prices. Nitrogen prices tended to respond immediately to decreases in corn futures prices. The nitrogen price responses to increasing corn futures prices were mixed.

An Examination of Farm Asset Returns
Provedor de dados: 31
Autores: Miller,   Lynn H.; Sherrick,   Bruce J.
A multi-factor capital asset pricing model is used to examine the return characteristics of physical assets comprising the farm asset portfolio. Physical assets analyzed are: 1) farm real estate; 2) machinery and motor vehicles; 3) crops stored on farm; and 4) livestock and poultry. Results for the years 1950-1990 indicate that unexpected inflation is more appropriate than the more commonly used realized inflation factor; and that the systematic risk component to these asset classes is, in general, low. Further, excess returns measures are significant for farmland, machinery, and crops stores on farm but not for livestock and poultry.

Tonga as a small island economy faces continuos trade deficits. The Government has identified the fisheries sector as having great potential. This paper explores current issues in the fisheries sector in Tonga. The emphasis in this paper will be on issues in fish exports from Tonga. It is perceived that barriers to trade have been a major contributing factor to the sector’s poor performance. The focus here is on the financial returns that fishermen receive and the influences that the sizes of operators and types of fish exported have on the return to the exporters/fishermen in Tonga.

An Experimental Analysis of a Points-Based System for Managing Multispecies Fisheries
Provedor de dados: 31
Autores: Anderson,   Christopher M.
An industry group has proposed a novel system for managing the Northeast Multispecies Fishery. Each harvester would be endowed with a budget of points, and each species would have a “point price,” or number of points that must be paid out of his budget when landing that species. By varying the point prices throughout the season, management could redirect effort across species. This paper presents a benchmarked experimental testbed of this management system, and shows that harvesters do respond to point prices, which can be chosen to support harvest of most of the allowable catch of each species without severely over-harvesting any of them.

Autores: Shobe,   William; Palmer,   Karen L.; Myers,   Erica; Holt,   Charles; Goeree,   Jacob K.; Burtraw,   Dallas.
The direct sale of emission allowances by auction is an emerging characteristic of cap-and-trade programs. This study is motivated by the observation that all of the major implementations of cap-and-trade regulations for the control of air pollution have started with a generous allocation of allowances relative to recent emissions history, a situation we refer to as a “loose cap.” Typically more stringent reductions are achieved in subsequent years of a program. We use an experimental setting to investigate the effects of a loose cap environment on a variety of auction types. We find that all auction formats studied are efficient in allocating emission allowances, but auction revenues tend to be lower relative to competitive benchmarks when the cap is...

An Experimental Analysis of Compliance in Dynamic Emissions Markets
Provedor de dados: 31
Autores: Stranlund,   John K.; Murphy,   James J.; Spraggon,   John M.
Two important design elements for emission trading programs are whether and to what extent firms are able to bank emissions permits, and how these programs are to be enforced. In this paper we present results from laboratory emissions markets designed to investigate enforcement and compliance when these markets allow permit banking.  Banking is motivated by a decrease in the aggregate permit supply in the middle of multi-period trading sessions. Consistent with theoretical insights, our experiments suggest that high permit violation penalties have little deterrence value in dynamic emissions markets, and that the main challenge of enforcing these programs is to motivate truthful self-reports of emissions.

This report provides insight into four aspects of modeling indirect land use caused by expanded biofuels production. The report was motivated by the National Biodiesel Board’s interest in better understanding how the California Air Resources Board (CARB) estimated an indirect land-use factor for soybean-based biodiesel of 66 gCO2e/MJ, which is more than three times greater than the direct emissions from the fuel. Four aspects of CARB’s modeling approach were examined: (1) why CARB estimates that more U.S. forest than pasture will be converted to cropland; (2) whether CARB’s predicted land-use changes are consistent with observed U.S. land-use changes in the past decade; (3) how CARB could account for double cropping; and (4) whether CARB’s assumption that...

An Implementable Index of Sustainability and Assessment of Energy Policy
Provedor de dados: 31
Autores: Sesmero,   Juan P.; Fulginiti,   Lilyan E.
Energy is a critical input in production and the main sources of energy in modern economies are exhaustible. Therefore sustaining aggregate consumption across generations requires reduction of the quantity of energy used per unit of output. Energy policies incentivize the deployment of new technologies that will not only increase energy efficiency but also impact the ease with which capital and materials can substitute for energy and hence the ability of societies to sustain consumption. Therefore an assessment of the impact of energy policies on sustainable consumption requires accounting for the link between technological progress and substitutability. We first allow for biased technical change and find that capital augmenting technical change (e.g....

An improved in vivo method for atrioventricular node ablation via thoracotomy
Provedor de dados: 56
Autores: MacIver,R.H.; Stewart,R.D.; Backer,C.L.; Tsao,S.; Harrington,D.A.; Mavroudis,C.
The atrioventricular (AV) node is permanently damaged in approximately 3% of congenital heart surgery operations, requiring implantation of a permanent pacemaker. Improvements in pacemaker design and in alternative treatment modalities require an effective in vivo model of complete heart block (CHB) before testing can be performed in humans. Such a model should enable accurate, reliable, and detectable induction of the surgical pathology. Through our laboratory’s efforts in developing a tissue engineering therapy for CHB, we describe here an improved in vivo model for inducing chronic AV block. The method employs a right thoracotomy in the adult rabbit, from which the right atrial appendage may be retracted to expose an access channel for the AV node. A...

An Improved Method for Calibrating Purchase Intentions in Stated Preference Demand Models
Provedor de dados: 31
Autores: Davies,   Stephen P.; Loomis,   John B.
The Orbit demand model allows the magnitude of the calibration to stated purchase intentions to vary based on the magnitude of the stated quantities. Using an empirical example of stated trips, we find that the extent of calibration varies substantially with less correction needed at small stated trips (–25%) but larger corrections at higher quantities of stated visits (–48%). We extend the Orbit model to calculate consumer surplus per stated trip of $26. Combining the calibrations in stated trips and value per trip, the Orbit model provides estimates of annual benefits from 60% to 111% less than the count data model.

An improved method for estimating water-mass ventilation age from radiocarbon data
Provedor de dados: 5
Autores: Devries, Tim; Primeau, Francois.
Existing methods for inferring the ventilation age of water masses in the ocean using radiocarbon data neglect the effects of diffusive mixing. in the presence of varying atmospheric Delta(14)C, this neglect produces spurious time dependence in the estimated ventilation ages. To correct this deficiency we propose a new method for estimating the ventilation age from sediment core radiocarbon data. The new method is formulated in terms of parameterized age distributions that account for the effects of advective and diffusive transport in the ocean. When applied to simulated radiocarbon data from an OGCM, the method is able to closely reproduce the modeled ventilation age, whereas other methods are not. We also applied the method to sediment-core radiocarbon...

An improved method for in vitro regeneration of common bean (Phaseolus vulgaris L.)
Provedor de dados: 115
Autores: Quintero-Jiménez,Anareli; Espinosa-Huerta,Elsa; Acosta-Gallegos,J. Alberto; Guzmán-Maldonado,H. Salvador; Mora-Avilés,M. Alejandra.
In vitro regeneration of common bean (Phaseolus vulgaris L.) is a requirement for genetic transformation which involves induction and development to the whole plant. Success in regeneration of common bean from tissue organ culture has been achieved to some extent in the last years. However, genotype effects in regeneration response as well as efficiency and reproducibility have been a limiting factor. Embryos, from four different varieties, were excised from sterilized mature seeds and cultured in Murashige and Skoog (MS) or Gamborg (GM) media containing 6-benzylaminopurine (BAP) (10 mg-1) and adenine (A) (0 or 20 mg-1). Efficient regeneration was achieved when inducing formation of differentiation of cells like bud clusters at the internodal segment of...

There is no index or criterion of aortic barodenervation, nor can we differentiate among rats that have suffered chronic sham, aortic or sino-aortic denervation. The objective of this study was to develop a procedure to generate at least one quantitative, reproducible and validated index that precisely evaluates the extent of chronic arterial barodenervation performed in conscious rats. Data from 79 conscious male Wistar rats of about 65-70 days of age with diverse extents of chronic arterial barodenervation and used in previous experiments were reanalyzed. The mean arterial pressure (MAP) and the heart rate (HR) of all rats were measured systematically before (over 1 h) and after three consecutive iv bolus injections of phenylephrine (PHE) and sodium...

An Integrated Assessment approach to linking biophysical modelling and economic valuation tools
Provedor de dados: 31
Autores: Kragt,   Marit Ellen; Bennett,   Jeffrey W.; Jakeman,   Tony.
Natural resource management (NRM) typically involves complex decisions that affect a variety of stakeholder values. Efficient NRM, which achieves the greatest net environmental, social and financial benefits, needs to integrate the assessment of environmental impacts with the costs and benefits of investment. Integrated assessment (IA) is one approach that incorporates the several dimensions of catchment NRM, by considering multiple issues and knowledge from various disciplines and stakeholders. Despite the need for IA, there are few studies that integrate biophysical modelling tools with economic valuation.  In this paper, we demonstrate how economic non-market valuation tools can be used to support an IA of catchment NRM changes. We develop a Bayesian...

Autores: Dortel, Emmanuelle; Sardenne, Fany; Bousquet, N.; Rivot, Etienne; Million, Julien; Le Croizier, Gael; Chassot, Emmanuel.
The Indian Ocean Tuna Tagging Program provided a unique opportunity to collect demographic data on the key commercially targeted tropical tuna species in the Indian Ocean. In this paper, we focused on estimating growth rates for one of these species, yellowfin (Thunnus albacares). Whilst most growth studies only draw on one data source, in this study we use a range of data sources: individual growth rates derived from yellowfin that were tagged and recaptured, direct age estimates obtained through otolith readings, and length-frequency data collected from the purse seine fishery between 2000 and 2010. To combine these data sources, we used an integrated Bayesian model that allowed us to account for the process and measurement errors associated with each...

This is the first record on the invasion of the Neotropical brown stink bug, Euschistus heros (F.) in Paraná County (latitude 31º 51' 9.6" S, longitude 60º 32' 11.2" W), Entre Ríos province, Argentina. Five adults were intercepted in 2009/2010, one in crop residues and four on soybean fields. The expanding range in the distribution of E. heros in the Southern Hemisphere is believed to be due to the increased commercial trade among countries, increase in the area cultivated with soybean, and the adoption of no-tillage cropping systems.

An Inverse Demand System for New England Groundfish: Welfare Analysis of the Transition to Catch Share Management
Provedor de dados: 31
Autores: Lee,   Min-Yang A.; Thunberg,   Eric M.
In 2010, the Northeast groundfish fishery transitioned from an effort-control system (Days-at-Sea) to an output-control system (catch shares). Simultaneously, a large decrease in aggregate catch was imposed in order to achieve biological objectives. This research examines the welfare effects of the transition to catch-share management by combining an inverse demand model for groundfish with a simulation based model of supply. The Generalized Differential Inverse Demand System is estimated for groundfish and imports using monthly data from 1994-2011 using a Generalized Method of Moments estimator. The estimated parameters are combined with simulated landings derived from a counterfactual policy scenario had ef- fort controls been retained instead of the...

Autores: Clancy,   Daragh; Kazukauskas,   Andrius; Newman,   Carol F.; Thorne,   Fiona S.
This paper conducts a detailed, micro-focused investigation on the implications of recent agricultural policy changes on the structure of production systems in Ireland, Denmark and the Netherlands in terms of farm numbers, system switching, specialisation, the role of economies of scale, on-farm investment, off-farm employment and economic viability. Given the close relationship between farm structure and agricultural production, the impact of the recent CAP reform on production decisions should give a good indication of the form agricultural structural change will take. Two competing hypotheses of post decoupling structural change are proposed; a ‘production inducing effect’ and an ‘expectations effect’. Using Irish, Danish and Dutch micro-data, which are...

An Investigation into the Net Benefits of Revegetating Agricultural Land with Indigenous Species in the Dryland Section of the Goulburn-Broken Catchment Area
Provedor de dados: 31
Autores: Trapnell,   Lindsay N.
Benefits ascribed to the revegetation of farming landscapes include enhancement of biodiversity, reduction in the advance of dryland salinity, sequestration of greenhouse gases, control of soil erosion, greater protection of agricultural activities from adverse weather conditions and an improved aesthetic value of rural lands. In this paper, economic analyses were performed to determine the net benefits to landholders of carrying out revegetation. Where the net benefits were insufficient to allow reasonable returns to be earned on the investment of marginal capital, an assessment was made of the amount and type of assistance that would be necessary to encourage landholders to adopt this improved system of land management.

An iron budget during the natural iron fertilisation experiment KEOPS (Kerguelen Islands, Southern Ocean)
Provedor de dados: 5
Autores: Chever, F.; Sarthou, G.; Bucciarelli, E.; Blain, S.; Bowie, A. R.
Total dissolvable iron (TDFe) was measured in the water column above and in the surrounding of the Kerguelen Plateau (Indian sector of the Southern Ocean) during the KErguelen Ocean Plateau compared Study (KEOPS) cruise. TDFe concentrations ranged from 0.90 to 65.6 nmol L-1 above the plateau and from 0.34 to 2.23 nmol L-1 offshore of the plateau. Station C1 located south of the plateau, near Heard Island, exhibited very high values (329-770 nmol L-1). Apparent particulate iron (Fe-app), calculated as the difference between the TDFe and the dissolved iron measured on board (DFe) represented 95 +/- 5% of the TDFe above the plateau, suggesting that particles and refractory colloids largely dominated the iron pool.

Since the enactment of the Economic Growth and Tax Relief Reconciliation Act of 2001, owners and operators of farms and ranches have opportunities to evaluate new estate planning strategies for the transfer of farm businesses to subsequent generations. However, with provisions of the Act to be phased in over several years, consideration must be given to having a "staged" estate plan. Under provisions of the current law, estate tax is repealed in the year 2010, but if Congress does not act, the legislation sunsets and returns to prior law January 1, 2011. This fact provides planning challenges for owners and operators of farms and ranches as the phase-in of provisions, the repeal in 2010, and the return to prior law relative to estate planning and business...

Shiga toxin-producing E. coli (STEC) O157 is a significant cause of foodborne illness in the United States. ERS estimated the economic cost of illness due to this pathogen— $405.2 million (in 2003 dollars)—using the most recent estimate (1997) of the annual number of STEC O157 cases by the Centers for Disease Control and Prevention (CDC) and medical and cost data from the Foodborne Diseases Active Surveillance Network. CDC is currently updating its estimate of annual cases. As new information becomes available, the ERS online Foodborne Illness Cost Calculator enables users to review and modify the assumptions underlying the STEC O157 cost estimate, such as the number of cases, and then recalculate the cost, adjusted for inflation for any year from 1997 to...

An Optimal Size for Rural Tourism Villages with Agglomeration and Club-Good Effects
Provedor de dados: 31
Autores: Tchetchik,   Anat; Fleischer,   Aliza; Finkelshtain,   Israel.
Helping to sustain a viable rural sector, rural tourism enjoys public support in many countries. We claim that due to club-good and agglomeration externalities in the rural accommodation market, public support should be integrated in a broader local development policy that regulates the number of accommodation units in a locality. To demonstrate this we extended an equilibrium model that accounts for product differentiation and oligopolistic competition to address club-good and agglomeration effects and applied it to data collected in north Israel. We show that under the prevailing regulation, the number of units is by far higher than the social optimum.

An Optimization Model for the Banana Northern Prawn Fishery
Provedor de dados: 31
Autores: Valle de Souza,   Simone; Gondro,   Cedric; Cacho,   Oscar J.
This study presents an optimal control model of the Banana Northern Prawn Fishery, one of the most important fisheries in Australia. The life cycle of this species involves migration between the sea, where the catch takes place, and the estuary, where post-larvae and juveniles develop. The model combines a stage-matrix population dynamics model and an economic model of sustainable catch. The controls involve the amount of effort allowed and the length of the fishing season. Life stages are defined in terms of prawn size, allowing catch revenue to be adjusted to the expected proportion of specific sized classes caught in a particular month of the year, hence providing a more realistic projection of profits when price is influenced by size. The model is...

South America harbors the largest freshwater diversity in the world (about 4,475 valid species). Aging studies of 153 species published in 92 papers were reviewed for this publication. They were categorized according to the journal where they were published, decade, number of researches per river basin, methods and structures most used to estimate age, validation methods, period and causes of the formation of the age ring and age of the fish in South America. Our results showed an increase in the studies of age and growth, especially in the Paraná river basin. Scales were the structure most used in the studies of aging. Most of the researchers did not validate age. On a continental level, there was no specific period for growth ring formation, but in...

An Overview of Globalisation and Economic Policy Responses
Provedor de dados: 31
Autores: Tisdell,   Clement A.
This is the draft of the introductory chapter of Clem Tisdell (ed.) Globalisation and World Economic Policies.  It highlights the varied dimensions of globalisation.  Trends in world exports of goods and services as a percentage of global GDP, and world FDI net inflow as a percentage of global GDP are used to indicate trends in economic globalisation.  In relation to non-economic measures of globalisation, particular attention is given to variations in international telephone traffic and the number of internet users and hosts.  Increasing globalisation of the media is an important feature of recent developments in globalisation, and has significant political, economic and cultural ramifications.  These aspects are highlighted. The chapter concludes with an...

An overview of the Philippine duck industry

Autores: Chang,   Hui-Shung (Christie); Dagaas,   Clarita T.; de Castro,   Nenita; Ranola,   Roberto; Lambio,   Angel; Malabayuabas,   Maria Luz.
The Philippine duck industry is dominated by smallholder production. At present, about 99 percent of the demand for duck products is met by domestic production. However, it is envisaged that as trade liberalisation continues, the Philippine duck industry will face increasing competition from overseas as well as from other products. Continuing survival, and growth, of the industry depends on its ability to compete on a globalised market, which, in turn, depends on efficiency in the production and marketing systems relative to competitors. The research objective is to provide an overview of the industry and identify industry issues.

An Unbalanced Nested Error Component Model for Estimating  Pest Damage Functions and the Value of Rootworm Bt Corn
Provedor de dados: 31
Autores: Dun,   Zhe; Mitchell,   Paul D.
We apply Antweiler’s (2001) double-nested unbalanced panel data model to estimate a western corn rootworm damage function using data from field trials in Illinois and Nebraska.  Results imply that expected yield losses for a one unit difference in the node injury scale are 16.4%.  Estimated random year and state effects are statistically significant, as is the estimated random experimental effect.  The experimental effect is relatively large indicating the tremendous variability in yield losses at the small scale for plots with the same node injury scale measure of root damage.  Using the estimated pest damage function to assess the value of Bt corn for farmers in Nebraska and Illinois, we find that, with a mean yield of 200 bu/ac, a yield CV of 25%, a...

Provedor de dados: 20
Autores: Faria Júnior, E.; de Carvalho Gaeta, J.; Santarosa Freire, A.
The aim of this study is to update the list of spiny lobsters  in the Abrolhos Archipelago. The data were obtained by scuba  diving during diurnal (8am to 5pm) and nocturnal (7pm to 11pm) visual censuses, from 2 to 12 meters depth. This work  presents the first record of Panulirus laevicauda on the Abrolhos Archipelago, confirm the previous unique record of Panulirus  echinatus and reinforce the occurrence of Panulirus argus. All the spiny lobster species of the genus Panulirus registered in  the Brazilian coast are now registered for  the Abrolhos National Marine Park reinforcing the importance of this marine  protected area.

The potentially significant role of the biogenic trace gas dimethylsulfide (DMS) in determining the Earth's radiation budget makes it necessary to accurately reproduce seawater DMS distribution and quantify its global flux across the sea/air interface. Following a threefold increase of data (from 15,000 to over 47,000) in the global surface ocean DMS database over the last decade, new global monthly climatologies of surface ocean DMS concentration and sea-to-air emission flux are presented as updates of those constructed 10 years ago. Interpolation/extrapolation techniques were applied to project the discrete concentration data onto a first guess field based on Longhurst's biogeographic provinces. Further objective analysis allowed us to obtain the final...

Anaerobic biodegradability of dairy wastewater pretreated with porcine pancreas lipase
Provedor de dados: 52
Autores: Mendes,Adriano Aguiar; Pereira,Ernandes Benedito; Furigo Jr.,Agenor; Castro,Heizir Ferreira de.
Lipids-rich wastewater was partial hydrolyzed with porcine pancreas lipase and the efficiency of the enzymatic pretreatment was verified by the comparative biodegradability tests (crude and treated wastewater). Alternatively, simultaneous run was carried out in which hydrolysis and digestion was performed in the same reactor. Wastewater from dairy industries and low cost lipase preparation at two concentrations (0.05 and 0.5% w.v-1) were used. All the samples pretreated with enzyme showed a positive effect on organic matter removal (Chemical Oxygen Demand-COD) and formation of methane. The best results were obtained when hydrolysis and biodegradation were performed simultaneously, attaining high COD and color removal independent of the lipase...

Anaesthesia and gonad sampling in the European flat oyster (Ostrea edulis)
Provedor de dados: 5
Autores: Suquet, Marc; Gonzalez, Ricardo; Lebrun, Luc; Queau, Isabelle; Mingant, Christian; Robert, Rene.
Controlled reproduction of the European flat oyster requires the development of tools adapted to this species, including a practical anaesthesia and gonad sampling protocol to facilitate sex determination and the verification of gametogenesis. Three replicate groups of 10 oysters (mean weight +/- SD: 29.9 +/- 8.5 g) were anaesthetised in 5 L containers using magnesium chloride designed either for laboratory (Flucka (R)) or agricultural (Dead Sea Work (R): DSW) use, at two concentrations (50 or 72 g L-1). No significant differences were observed in the percentages of oysters anaesthetised or subsequent oyster mortality with the different anaesthetics or concentrations, but increasing water temperature from 14.9 to 18.8 degrees C significantly increased the...

Este trabalho comparou biomecanicamente o uso de um implante ósseo cortical alógeno preservado em mel para a estabilização de osteotomia transversa de ílio em cães, bem como o uso de hemicerclagem de fio de aço isoladamente frente às forças de flexão. Foram testadas bilateralmente 13 pelves caninas em que um lado foi estabilizado com implante ósseo e o outro com hemicerclagem de fio de aço isoladamente. Os protótipos estabilizados com implante ósseo foram estatisticamente mais resistentes às forças de flexão do que os estabilizados com hemicerclagem de fio de aço usada isoladamente. Os resultados demonstraram que o uso de implante ósseo cortical alógeno é uma alternativa viável para a fixação da osteotomia ilíaca em cães.

O pinhão-manso (Jatropha curcas L.) vem ganhando importância por seu potencial como insumo ao biodiesel. Estudos visam à adequação agronômica e a cultura de tecidos contribui indiretamente com este aspecto, auxiliando em pesquisas aplicadas como em biotecnologia, em situações que visam à regeneração de plantas. Nesse intuito, é fundamental avaliar, durante os períodos de cultivo dos calos, o comportamento dos metabólitos primários. A massa calogênica, por ocasião da inoculação, não apresentou reserva na forma de carboidratos. Aos 42 dias iniciou a absorção da sacarose do meio, enquanto o acúmulo no explante ocorreu a partir dos 98 dias de cultivo. O teor de aminoácidos foi alto no dia da inoculação e, por volta dos 98 dias, tanto os níveis de aminoácidos...

Provedor de dados: 31
Autores: Pereira,   Vanessa da Fonseca; Mendonca,   Talles Girardi de; Reis,   Bricio dos Santos.
Due to growing consumer demands regarding product quality and the social and environmental aspects of the production process, there is a need to redefine the agricultural productive structure so as to make it sustainable. The Integrated Production System in Coffee (CIP) aims to meet these new requirement standards. The system, however, is still very recent and requires more detailed studies to identify its strengths and weaknesses. Therefore, the objective of this work is to carry out a comparative analysis of the economic viability and the risk associated to the conventional and integrated systems of coffee production in the farm property of São João, in the Coimbra district in Minas Gerais state. The method used was the calculation of the viability and...

Análise comparativa do meio físico e socioeconômico de três municípios com parques florestais: Araponga, Caparaó e São Roque de Minas - MG.
Provedor de dados: 14
Autores: COSTA, T. C. e C. da; COSTA, L. M. da.
O meio físico, a localização geográfica, e a história de ocupação de um município contribuem na sua socioeconomia. Do mesmo modo, limitações físicas naturais resultam em pouca alteração antrópica, protegendo áreas que podem vir a ser transformadas em unidades de conservação, sob leis de proteção ambiental. Estas áreas, como por exemplo, parques florestais, apresentam potencial turístico, como uma alternativa socioeconômica. Este trabalho é uma análise comparativa de informações municipais socioeconômicas, históricas e do meio físico, com o objetivo de investigar uma possível influência de parques florestais na socioeconomia de municípios do Estado de Minas Gerais que contém grande parte de suas áreas com topografia acidentada e altitude elevada. Foram...

Autores: Grunow,   Aloisio; Gallon,   Alessandra Vasconcelos; Beuren,   Ilse Maria.
In a competitive environment, it is not enough to simply coordinate and promote the efficiency of a company’s internal activities. It is also necessary to ensure that the activities which form part of the company’s “value chain” are organized in a competitive way. From this perspective, the objective of this article is to analyze the “value chain” of poultry production and the cost of animal feed in every phase of the Seara Alimentos S.A chain. The methodology consisted of exploratory research in a case study using a predominantly qualitative approach. The results of the study are the stages of the productive cycle and the costs of the animal feed throughout the “value chain” in a poultry agribusiness. It was concluded that estimating the production’s...

Análise da relação entre desmatamento e bem-estar da população da Amazônia Legal
Provedor de dados: 123
Autores: Prates,Rodolfo Coelho; Bacha,Carlos José Caetano.
Este artigo analisa, empiricamente, a relação entre o desmatamento da floresta amazônica e o bem-estar da população local, mensurando os impactos de uma redução da área desmatada sobre o bem-estar. Utilizou-se o Índice de Desenvolvimento Humano Municipal (IDH-M) como indicador de bem-estar. Para isso, com base nos dados em nível municipal do Censo Agropecuário de 1995 foi estimada, para cada estado, uma função de produção Cobb-Douglas com três fatores de produção: terra, capital e trabalho. Com a função de produção e por meio do método de programação não linear (condições de Kuhn-Tucker), verificou-se a dimensão do impacto sobre o PIB agropecuário e do agronegócio quando há uma restrição na utilização do fator terra de modo a cumprir a legislação florestal...

Análise de componentes principais entre características morfogênicas e estruturais em capim-marandu sob lotação contínua
Provedor de dados: 65
Autores: Silva,Sila Carneiro da; Sbrissia,André Fischer.
A análise de componentes principais é uma técnica de análise multivariada que tem sido usada com pouca frequência na pesquisa com plantas forrageiras. Dessa forma, o objetivo do presente trabalho foi verificar se as hipóteses já testadas de acordo com técnicas univariadas podem ser validadas por meio de análise de componentes principais. Assim, duas análises foram realizadas. Na primeira, mais de 80% da variação do conjunto de dados foi explicada pelos primeiros três componentes principais, os quais relacionaram, basicamente, padrões de compensação tamanho/densidade populacional de perfilhos e discrepâncias na forma de se avaliar a forma do perfilho (relação folha: colmo ou razão área foliar: volume por perfilho). Na segunda, os três primeiros componentes...

O Brasil ocupa o quarto lugar mundial em consumo de fertilizantes; dentre esses, destaca-se o fertilizante mineral misto como o mais consumido no País. Depois da atualização da legislação brasileira de fertilizantes em 2004, muitos produtores desses insumos afirmam que houve aumento excessivo no rigor da legislação em relação à fiscalização dos teores de nutrientes neles contidos. Dentro desse contexto, os objetivos deste trabalho foram aplicar técnicas de análise estatística exploratória e descritiva e de regressão logística aos dados de análises fiscais de fertilizantes realizadas pelo Ministério da Agricultura, Pecuária e Abastecimento (MAPA), nos anos de 2008 a 2010, buscando indicadores da contribuição das fontes de variação referentes aos fatores...

Análise de perfis de ácidos graxos como ferramenta para estudos em microbiologia do solo.
Provedor de dados: 14
Autores: FERNANDES, M. F.; CHAER, G. M.
Os microrganismos do solo participam na regulação de um grande número de processos de importância ambiental e econômica, como a ciclagem de nutrientes, a agregação do solo, o balanço de gases de efeito estufa entre a litosfera e a atmosfera, a degradação de compostos xenobióticos, dentre outros. Com a percepção de que o controle destes processos ocorre por interações complexas entre diferentes taxa microbianos, há, atualmente, um consenso sobre a necessidade de se adotar as comunidades microbianas como as unidades básicas nas investigações de ecologia. Os primeiros estudos sobre a função e a composição das comunidades microbianas em amostras ambientais baseavam-se no isolamento e na caracterização de membros cultiváveis destas comunidades. Além de não...

A resistência genética constitui alternativa sustentável para o controle da mancha-de-phoma na cultura do mamoeiro. No entanto, estudos básicos são necessários para a escolha de genitores e combinações híbridas resistentes à doença. Neste trabalho, por meio de cruzamento dialélico, envolvendo oito genótipos de mamão, quatro do grupo Solo e quatro do grupo Formosa, estimou-se a capacidade geral e específica de combinações híbridas quanto à resistência a mancha-de-phoma. Os genitores, bem com os híbridos obtidos dos cruzamentos foram avaliados em blocos casualizados, com quatro repetições. Quantificaram-se em duas épocas, março e maio de 2010, as severidades de mancha-de-phoma em folha, com auxílio de escala diagramática. Os genótipos Maradol JS12-N, Sekati...

O Acre apresenta condições de clima e solo propícias ao cultivo de fruteiras tropicais, incluindo a cultura do abacaxizeiro que vem apresentando um aumento em área plantada em diversos municípios do estado nos últimos anos. Todavia, esse crescimento não tem sido acompanhado pelo uso de tecnologias que possam aumentar a produtividade, resultando em rendimento ainda considerado baixo. Na maior parte do ano o fruto do abacaxi não é encontrado nas gôndolas dos supermercados o que reflete em preços elevados, principalmente, por ser proveniente de outros estados. Portanto, a produção ainda não atende à forte demanda do mercado local, havendo a necessidade da importação de outras partes do País. Esse cenário pode garantir aos agricultores acrianos a venda do...

Autores: ANDRADE NETO, R. de C.; SA, C. P. de; OLIVEIRA, J. R. de; MUNIZ, P. S. B.; ALMEIDA, U. O. de.
Com a produção de aproximadamente 2,08 milhões de toneladas, o Brasil é o quarto maior produtor de melancia do mundo, ficando atrás da China, Turquia e Irã (FAO, 2015). Segundo dados do IBGE (2014), a área plantada com melancia no País, em 2013, foi de 93.190 hectares e a quantidade produzida 2,16 milhões de toneladas. No Acre, esses valores foram de 1.149 hectares e 16,2 mil toneladas. O cultivo de melancia no estado, praticado por agricultores familiares, é caracterizado pela adoção de baixas tecnologias de produção. Apesar disso, a cultura tem se expandido nos últimos anos, contribuindo para diversificar a produção e aumentar a renda. O objetivo deste trabalho é analisar a sazonalidade e o comportamento dos preços de melancia nos últimos seis anos...

Análise dos fatores determinantes da viabilidade de implantação do contrato futuro de suínos vivos no Brasil
Provedor de dados: 31
Autores: Santos,   Adriana Helena Gama dos; Aguiar,   Danilo Rolim Dias de.
O objetivo deste estudo é analisar a viabilidade de utilização de um contrato futuro referenciado em suínos, no Brasil. O interesse decorre da importância da cadeia de suínos neste país, que, apesar de relevante, apresenta grande instabilidade, principalmente quando se avaliam os riscos de preços do produto. No entanto, a introdução de um novo contrato não é uma questão simples, visto que muitos contratos são lançados no mercado, mas tempos depois fracassam. Assim, o estudo do mercado e das características da commodity deve ser realizado antes da inovação contratual, para que os pontos positivos e possíveis pontos problemáticos sejam identificados. O modelo utilizado foi desenvolvido por Pennings e Leuthold (1999), que avaliaram as características micro e...

ResumoA crescente tendência na fruticultura é o desafio de produzir frutassaudáveis e com qualidade. O mercado internacional, diante das novastendências do consumidor, exige alimentos seguros e livres de qualquer tipode agravante à saúde humana. O setor frutícola é um dos mais importantessegmentos do agronegócio brasileiro e, além da sua elevada rentabilidade eexpressiva utilização de mão-de-obra, a fruticultura constitui-se em umavaliosa alternativa para a expansão das exportações brasileiras de produtosagrícolas. O reflexo das novas exigências internacionais é a adoção deselos de certificação que comprovam a qualidade e sanidade do produto. Asrecentes crises alimentares na Europa fizeram com que os consumidores semobilizassem para exigir maior clareza...

Foi objetivo, também, identificar os componentes que exerceram maior influência sobre os custos finais da atividade por meio dos resultados econômicos e indicadores técnicos de desempenho econômico. Para a realização das análises econômicas, os produtores foram divididos em dois grupos, em função do vínculo com a Cooperativa, sendo sócios e não-sócios. A receita bruta da atividade foi suficiente para cobrir os custos operacionais efetivos e totais nas propriedades 1, 2, 3 e 5. Os itens que compõem o custo operacional efetivo de produção do leite foram responsáveis por porcentuais superiores a...

Mandioca: Baixa oferta sustenta preço em agosto – O volume de raiz de mandioca processada seguiu baixo em agosto nas regiões acompanhadas pelo Cepea, devido, principalmente, ao clima bastante seco. Além disso, a quantidade de raízes de segundo ciclo disponível para a colheita também está menor em relação à de anos anteriores. De acordo com a Secretaria de Agricultura do Estado do Paraná (SEAB/Deral), até o final de agosto, mais de 50% da mandioca disponível para a colheita naquele estado já havia sido colhida, sendo este um forte fundamento de que a disponibilidade de raízes é menor neste ano que nos anteriores. Nesse cenário, os preços mantiveram-se praticamente estáveis de julho para agosto. Algumas regiões, inclusive, chegaram a registrar ligeiras altas...

Mandioca: Cotações se sustentam em junho – Junho caracterizou-se pelo aumento da oferta da raiz para a indústria de derivados de mandioca, por ser período de pico de safra. Diante deste quadro, principalmente na segunda quinzena do mês, houve pressão sobre as cotações do produto. Apesar disso, a média de junho ainda foi maior que a de maio. O preço médio da mandioca para fecularias foi de R$ 246,31/t (R$ 0,4238/grama de amido na balança hidrostática de 5 kg) em junho, alta de 13,2% frente à de maio, que foi de R$ 217,64/t. Considerando a média da última semana de maio (R$ 237,81/t) e igual período de junho (R$ 239,31/t), houve aumento de 0,6% (Figura 1). De modo geral, ao longo de junho prevaleceu a intenção de colheita na maioria das regiões acompanhadas...

Menor oferta sustenta cotação em maio – O mês de maio foi caracterizado pela menor oferta de mandioca para a indústria de fécula, levando à diminuição na quantidade de mandioca processada pelas fecularias. Ainda que seja período de safra, a disponibilidade de mandioca de segundo ciclo é menor em relação a anos anteriores e, além disso, agricultores mantiveram-se retraídos em relação à colheita. Esses produtores não tiveram necessidade de caixa e aguardam preços ainda maiores nos próximos meses. O excesso de chuvas em alguns períodos de maio prejudicou a colheita, dificultando os trabalhos e diminuindo a quantidade ofertada à indústria. Vale destacara, também, que houve menor número de mão-de-obra disponível para a colheita, visto que parte dos agricultores...

Mandioca: Preços recuam após três meses de alta ? A oferta de mandioca seguiu elevada para a indústria de fécula das regiões acompanhadas pelo Cepea em março. Este quadro foi atribuído aos preços favoráveis da cultura e também pelo clima favorável ao longo do período. Por conta destes fatores, as cotações que vinham se valorizando expressivamente em meses anteriores, passaram a ter elevações menos intensas. Em março, a tonelada da raiz destinada às fecularias foi cotada à média de R$ 249,71 (R$ 0,4343/ grama de amido, considerando a balança hidrostática de 5 kg), subindo 5,4% frente à de fevereiro (R$ 236,89/t). Esta alta é pouco expressiva quando comparada com a de meses anteriores, que foi de até 15%. Comparando o preço médio de R$ 236,89/t da última...

Mandioca: Cotações têm forte alta em setembro – Com forte diminuição na oferta, em setembro, os preços da mandioca pra fecularias acumulou forte alta nas regiões acompanhadas pelo Cepea. Este fato esteve atrelado à condições climáticas desfavoráveis a colheita, bem como pela retração dos agricultores em relação a colheita, o que fez o processamento diminuir mais de 50% frente ao do mês anterior. A média das regiões acompanhadas pelo Cepea esteve no período em R$ 257,95/t (0,4486/grama de amido na balança hidrostática de 5 kg), o que significou reajuste de 11,1% ante a média de agosto, que foi de R$ 232,18 (R$ 0,4037/g). Havendo indisponibilidade de raízes de segundo ciclo, estiagem e retração dos agricultores em relação a colheita, os preços subiram em...

Mandioca: Aumento na oferta pressiona cotações – A melhora nas condições climáticas, e, conseqüentemente, de colheita, favoreceu o aumento da oferta de raízes para a indústria de fécula de setembro para outubro, pressionando as cotações. Algumas regiões, no entanto, seguiram com problemas de abastecimento, o que levou algumas empresas a interromper as atividades de produção, fato que gerou excedente para as empresas ativas, sendo este também um fundamento para a queda de preços. O preço médio de outubro foi de R$ 253,96/t (R$ 0,4417/grama de amido na balança hidrostática de 5 kg), 1,5% menor que o de setembro, de R$ 257,95/t (R$ 0,4486/g).

Análise econômica para a pecuária de corte em pastagens melhoradas no Acre.
Provedor de dados: 14
Autores: SA, C. P. de; ANDRADE, C. M. S. de; VALENTIM, J. F.
A pecuária de corte é a atividade com maior expressão econômica do setor agropecuário do Estado do Acre, representando aproximadamente 40% do valor bruto da produção. Contudo, sistemas de produção caracterizados como tradicionais, que apresentam baixos índices zootécnicos, predominam na maior parte das pequenas, médias e grandes propriedades. Consequentemente, o setor apresenta baixa produtividade e rentabilidade e tem causado impactos ambientais negativos decorrentes de desmatamentos, que implicam em perda de biodiversidade e degradação dos solos. Observa-se que a retração da atividade é ocasionada por diversos fatores, com destaque para medidas voltadas à redução nas taxas de desmatamento, o que limita a expansão das áreas de pastagens, e para a baixa...

Análise espacial da produtividade agrícola no Estado do Paraná: implicações para o seguro agrícola
Provedor de dados: 31
Autores: Ozaki,   Vitor Augusto.
This paper analyses the spatial pattern of the agricultural yield data. Using the spatial statistics, it is possible to estimate some parameters of the semivariogram to study the problem of the systemic risk, which has great implications for the crop insurance program in Brazil. In particular, the “range” parameter was estimated. This parameter measures the distance, in which the spatial correlation tends to zero. For the empirical analysis, county yield data was used provided by IBGE, for soybean and corn, in the state of Paraná, through 1990 and 2002. The results showed that there is spatial dependence in every year analysed, going to zero in relatively long distances (in km).

Introdução e objetivos: A Escherichia coli, uma das principais habitantes do trato intestinal de seres humanos e das aves, pode ocasionar quadros entéricos nas duas espécies [1]. Drásticas mudanças ecológicas e comportamentais do ser humano, como aumento exponencial da população e intenso contato com pets exóticos, colaboraram para a emergência de zoonoses e prejuízos na própria saúde animal [2]. A bactéria, pertencente à família Enterobacteriaceae, pode ser classificada sorologicamente, filogeneticamente e molecularmente [3,4,5]. EPEC é um grupo de E. coli diarreiogênica que produz alterações características nas células intestinais, como a lesão A/E (attaching and effacing), mas não produzem toxinas shiga, enterotoxina termolábil ou termoestável, sendo...

A comunidade nativa de fungos micorrízicos arbusculares (FMA), presente em amostras de raiz e de solo rizosférico de 15 genótipos de milho contrastantes para eficiência no uso de fósforo, foi avaliada pela técnica de eletroforese em gel de gradiente desnaturante (DGGE). Foram amplificados fragmentos do DNA ribossomal com primers específicos para as famílias Acaulosporaceae e Glomeraceae. Os primers para a família Glomeraceae foram eficientes em diferenciar a estrutura da população de fungos micorrízicos, indicando grande diversidade da comunidade entre os genótipos. No DGGE específico para Glomeraceae, foram observadas bandas exclusivas nas linhagens eficientes L228-3 e L3, ambas cultivadas sob baixo teor de fósforo, indicando uma associação preferencial...

A cultura da cana-de-açúcar encontra-se em expansão no Estado de São Paulo. Esse fato decorre principalmente de perspectivas favoráveis da demanda por álcool combustível nos mercados interno e externo e dos preços competitivos do açúcar brasileiro no mercado internacional. São Paulo foi responsável, em 2007, por cerca de 60% da produção brasileira de cana-de-açúcar. Algumas regiões do estado apresentam melhores condições para esse cultivo em razão da qualidade do solo, da adequação climática, dos regimes pluviais, das condições topográficas, além da infraestrutura logística. A sustentabilidade é um ideal sistemático que se constrói principalmente pela ação integrada da busca do desenvolvimento econômico em harmonia com a conservação ambiental. Os pontos...

Objetivou-se estimar os custos de produção e lucratividade do caju in natura na Regional de Jales, noroeste do Estado de São Paulo. Os dados foram levantados junto a produtores, a partir da aplicação de questionário e da elaboração de planilhas, para caracterizar todo o processo produtivo e realizar análise econômica. A produção de fruta para mesa exige um sistema de cultivo mais intensivo, principalmente no controle de pragas e doenças; por sua vez, eleva o custo de produção que, via de regra, é compensada pelos preços alcançados. Os custos de produção são altos, mas o que deve ser destacada é a participação relativa das embalagens que pode chegar a um terço do custo operacional efetivo, seguido pelos custos pós-colheita. Os indicadores de lucratividade...

Autores: Castellini,   Alessandra; Pisano,   Cinzia.
Since 1995, the Barcelona Process aims to establish a free trade area between Mediterranean countries by 2010. The most commercialized products from Mediterranean countries are fruit and vegetables. The agreement defines, only for some products, preferences at the entrance of the EU market, limited concession for each partner for single products,  limited quantities and calendars. This work tries to analyse the impact of the liberalization on the Italian products applying a gravity model in order to asses the Italian import flows from eight Mediterranean countries which signed the Barcelona agreement. The econometric estimation includes fruit and vegetables at the aggregate level and some specified products that enter in competition with typical Italian...

La displasia de cadera (DC) es una enfermedad poligénica caracterizada por laxitud articular y pérdida de congruencia que conduce a la osteoartritis (OA). En muchas condiciones patológicas, incluyendo a la artritis puede observarse un aumento de la síntesis de MMP-1. El promotor del gen MMP-1 contiene elementos de respuesta a citoquinas, los factores de trascripción AP-1 y SAF-1 que se hallan aumentados en OA. El objetivo del presente estudio fue la identificación y análisis de polimorfismos en el promotor del gen MMP-1 canino y su asociación a la OA secundaria a DC. Basados en la secuencia de referencia NCBI_006587, se detectaron dos nuevos polimorfismos, Indel CTGCCCT (bp31986794) y una sustitución C&gt;T (bp31986815) que fueron seleccionadas para su...

Análisis de clasificación de series temporales: el caso de la salinidad en la Ciénaga Grande de Santa Marta
Provedor de dados: 20
Autores: Giraldo-H., R.; Martínez-C., J.; Hurtado-T., L.H.; Zea, S.; Madera-R., E.R.
Se realizó una clasificación numérica de 21 estaciones de monitoreo del sistema laguno -estuarino comprendido por la Ciénaga Grande de Santa Marta y el Complejo Pajarales, de acuerdo a su similaridad en el comportamiento de la salinidad del agua. Se utilizó información quincenal comprendida entre enero de 1987 y octubre de 1991. Debido a la estructura de autocorrelación de los datos fue necesario emplear los modelos ARIMA de series de tiempo en primer lugar, y posteriormente aplicar una técnica de clasificación normal con los coeficientes de la representación infinita AR calculados para cada estación. Los resultados del análisis fueron coherentes con las hipótesis planteadas acerca de la distribución de la variable en el sistema.

Análisis de endemismo de moluscos dulceacuícolas de Chile
Provedor de dados: 97
Autores: FUENTEALBA,CARMEN; FIGUEROA,RICARDO; MORRONE,JUAN J.
La diversidad geológica y climática de Chile continental permite la diferenciación de una gran variedad de ecosistemas terrestres y acuáticos. La evidencia de los actuales patrones de distribución de especies dulceacuícolas sugiere en gran medida una relación con las glaciaciones del Pleistoceno y algunos eventos tectónicos postglaciales que afectaron la hidrografía del país. Las especies de moluscos dulceacuícolas en Chile, a diferencia de las especies marinas, han sido escasamente valoradas, a pesar del papel que cumple un importante número de ellas en los ecosistemas. Actualmente no existen estudios biogeográficos que permitan establecer patrones distribucionales y los procesos que los condicionaron. Un análisis de parsimonia de endemismos (PAE) y de...

Autores: Cardenete,   Manuel Alejandro; Fuentes Saguar,   Patricia D.; Polo,   Clemente.
RESUMEN: En este artículo se estiman las intensidades energéticas y emisiones de CO2 para la economía andaluza en el año 2000. Las intensidades energéticas de las ramas productivas se calculan en varios escenarios empleando un modelo SAM especificado con la matriz de contabilidad social elaborada por los autores. Las emisiones se estiman con el modelo input-output, distinguiendo la polución intermedia de la originada por la demanda final. Los resultados muestran la existencia de importantes variaciones en intensidades entre ramas y también las sustanciales variaciones que acaecen al endogeneizar el consumo y la inversión. La estimación de las emisiones en el año base resulta bastante satisfactoria y las simulaciones realizadas muestran el sustancial...

Análisis de la cadena productiva de la ganadería bovina de doble propósito en la costa oaxaqueña.
Provedor de dados: 32
Autores: Flores Verduzco, Samuel.
Una de las principales cadenas productivas rurales del país lo constituye la ganadería bovina productora de carne, la cual no satisface la demanda nacional del producto, debido a que se necesita importar cantidades significativas (hasta 40% del consumo para años específicos). Por otra parte, el país exporta alrededor de 1.5 millones de becerros en pie y novillonas al año. El objetivo del trabajo fue realizar un diagnóstico de la actividad ganadera productora de carne de bovino en la Costa de Oaxaca, utilizando para ello la metodología de la cadena o red de valor, mediante la cual se determina el proceso de creación de valor, y la forma como este se genera y distribuye entre los agentes participantes. La información se obtuvo mediante el levantamiento de...

Autores: Angulo,   Ana Maria; Mtimet,   Nadhem; Gil,   Jose Maria.
RESUMEN: En este trabajo se analiza la demanda de alimentos en España considerando la relación existente entre salud y dieta. Se plantea la maximización de una función de utilidad que depende de las cantidades demandadas de los distintos alimentos y del nivel de salud alcanzado, sujeto a dos restricciones: la presupuestaria y la relativa a la función de producción de salud. La solución al problema conduce a la estimación conjunta de un sistema de ecuaciones con dos componentes, una ecuación referida a la calidad de la dieta y un sistema de demanda de alimentos. Los resultados obtenidos indican, por un lado, que la introducción de la calidad de la dieta en un sistema de demanda (frente a un modelo que incluya únicamente renta y precios) modifica las...

The cardiac behaviour of the humpback whale (Megaptera novaeangliae) is described, in order to mathematically characterize its electrocardiogram (ECG) using the Dynamic Components of the System (DCS) and the probability theory. Images of 199 cardiac complexes from the electrocardiography register of a humpback whale were digitalized, determining the frequency apparition of each DCS and calculating the probability of those which frequency was greater or equal than four. Application of the probability theory to the electrocardiography analysis of the whale allows its mathematical, objective and reproducible characterization.

Autores: Celso Arellano,   Pedro Luis; Cortes Fregoso,   Jose Hector.
What are the most salient features of the Mexican sugar agroindustry's relative technical efficiency? This paper looks at a very preliminary approach to the relative technical efficiency (RTE) conditions prevailing in the sugar refineries of the country, with the support of an empirical production function. With this goal in mind, an RTE examination of the national sugar refineries is undertaken based upon data envelopment analysis (DEA), a non-parametric mathematical programming technique that allows for the RTE coefficients estimation for the decision making units (DMU) taken into account. The stance considered deals with an input oriented approach and the RTE indices are generated by a variable returns to scale (VRE) technology. The sample used deals...

En el método del experimento de elección se supone que el entrevistado es perfectamente racional, está informado y maximiza su utilidad siguiendo una regla de elección perfectamente compensatoria. Sin embargo, es posible que los individuos empleen otras reglas de decisión en sus elecciones para simplificar el esfuerzo cognitivo del ejercicio propuesto. En este trabajo se emplea la metodología de los valores de corte para incorporar en el experimento de elección reglas de decisión no compensatorias, y se amplia esta metodología para identificar respuestas inconsistentes. Los resultados indican que el empleo de los valores de corte mejora la capacidad descriptiva de los modelos de elección, y puede ser muy útil para la identificación de inconsistencias en la...

Autores: Robayo-Avendaño,Angélica; Galindo-Mendoza,María G.
El desarrollo de Organismos Genéticamente Modificados (OGM) es una alternativa eficiente para el control de plagas en el sector agrícola, pero su aplicación en cultivos de maíz (Zea mays L.) ha generado preocupación por proteger la riqueza genética de parientes silvestres. Por ello, las evaluaciones en este tipo de cultivos se orientan a controlar probables dispersiones de polen de maíz Genéticamente Modificado (GM) hacia parientes silvestres. Aunque los valores de distancias de aislamiento se consideran como parámetros para establecer criterios de bioseguridad, es necesario respaldar más las distancias adoptadas. Por lo tanto, el objetivo de este estudio fue analizar de forma espacial la dispersión de partículas de polen de maíz GM. Para ello, se...

Autores: Escobar Villagran, Bernardo Samuel.
El acuífero Texcoco es el principal recurso de agua de 12 municipios en la parte oriente del Valle de México, con una población de cerca de un millón y medio de habitantes. El desarrollo económico de esta región depende fuertemente de la posibilidad de alcanzar un manejo sustentable del acuífero, el cual está sobre-explotado actualmente, a pesar de que el grado de sobre-explotación es desconocido. Ya que el conocimiento de un valor creíble de la sobre-explotación es completamente indispensable para poder elaborar e implementar un plan de manejo sustentable del acuífero, el objetivo de este trabajo fue analizar las fuentes de incertidumbre y errores en la estimación de la sobre-explotación. Para este propósito se aplicaron dos métodos: a) el método del...

Autores: Sabbagh Sánchez, Adriana.
Actualmente los productores mexicanos de papa fresca (Solanum tuberosum L.) sostienen que un aumento en el consumo per cápita sería la solución a los problemas relacionados con el mercado del tubérculo. Con la finalidad de conocer la tendencia del consumo de papa fresca en el largo plazo, se formuló y estimó un modelo de ecuaciones simultáneas compuesto de dos ecuaciones de oferta, una de demanda, cuatro ecuaciones de precios y dos identidades; el modelo fue  estimado por el  método de mínimos cuadrados ordinarios en dos etapas usando datos nacionales anuales en el periodo  1960-2006. Los resultados indican que en el periodo 2000-2007 el consumo per cápita anual de papa fresca fue de 16 kg por habitante, y que los factores que explican el comportamiento de...

Análisis de la utilización de la captura por unidad de esfuerzo de pescadilla de red (Cynoscion guatucupa) como índice de abundancia anual. Período 1992-2004
Provedor de dados: 20
Autores: Perrotta, R.G.; Ruarte, C.O.
The stripped weakfish (Cynoscion guatucupa)  caught in Brazil, Uruguay and Argentina (SW Atlantic) has a wide latitudinal distribution (22° S-43° S). In Argentina there are two main fishing areas, the Argentine-Uruguayan Common Fishing Zone and 'El Rincón', southern zone of the Buenos Aires littoral. The importance of the species makes it necessary to define an annual abundance index that would allow to diagnose the state of the stock. The model adjusted to calculate the index is the General Linear Model. The factors used were Year, Quarter, Length, Stratum (4 categories) and sub-areas (5 categories), all statistically significant. The problem generated by the presence in the model of first order interactions that include the Year factor is discussed. The...

Análisis de las características generales del sector informal en el Ecuador - segmento pequeños comercios
Provedor de dados: 122
Autores: Torres Galárraga, Ana.
La informalidad muestra su complejidad desde su propia definición. La Organización Mundial del Trabajo (OIT), en su documento Decent Work and the Informal Economy (International Labour Conference 90th Session 2002), define que la característica primordial de los trabajadores informales es el no ser reconocidos ni protegidos por los marcos legales y regulatorios. Otros aspectos de esta complejidad son la falta de protección social, de reconocimiento de los derechos de propiedad o la dependencia de instituciones informales para el desarrollo de su actividad; ejemplo de ellas son los chulqueros, a quienes recurren los informales para tener acceso a crédito o el contrabando para abastecerse de mercadería. En los varios estudios sobre el sector informal, se...

Análisis de las consecuencias del comportamiento adaptativo individual sobre la estabilidad poblacional: El caso del forrajeo óptimo
Provedor de dados: 97
Autores: VALDOVINOS,FERNANDA S; URBANI,PASQUINELL; RAMOS-JILIBERTO,RODRIGO.
Trabajos tempranos basados en la teoría de Sistemas Dinámicos, demostraron que mientras mayor sea el número de poblaciones en interacción ecológica, el sistema tiende a ser más inestable. Sin embargo, la evidencia empírica indica que las poblaciones naturales presentan más frecuentemente dinámicas estables, aun estando inmersas en comunidades complejas. Entre los mecanismos que promueven la estabilización poblacional, se encuentra el comportamiento adaptativo de los individuos componentes de las poblaciones. En este trabajo se analizan los avances teóricos respecto del rol del forrajeo óptimo (FO) como fuerza estabilizadora de las dinámicas poblacionales, en comunidades modelo de diferente nivel de complejidad estructural. El análisis se organiza en torno...

Autores: Garcia,   Teresa.
El consumo de vino en España ha ido disminuyendo en los últimos años, cediendo parte de su mercado a otras bebidas. Esta circunstancia, unida a los cambios en las preferencias y en las pautas de consumo del producto, crea una difícil situación para las empresas del sector vinícola. Por tanto parece fundamental que las empresas vinícolas analicen su situación de cara a adoptar unas adecuadas estrategias empresariales que les permitan hacer frente a la situación actual y a un futuro que se plantea complicado. Este estudio se enmarca en Navarra, región situada en el Norte de España, en el extremo occidental de los Pirineos. Es una de las zonas vitivinícolas españolas más antiguas y gran parte de su producción vinícola se acoge a la Denominación de Origen...

The objective is to make the investment sensibility analysis in drop irrigation by gravity in sugar cane production, there are three variables involved into the sensibility analysis for both of the irrigation systems: Cane production by hectare (it was sensibilized to low prices), sell price for sugar cane ton (it was sensibilized to low prices), and variations in the production's direct costs (sensibilized to high prices). The Novelo's methodology for sensibility analysis (1944) was used. The three variables involved into the sensibility analysis showed differences to support the outcome results got with the irrigation drop system over the irrigation gravity system by drop.

Autores: Villacís Navas, Yomar Tamara.
El manejo de residuos sólidos producidos en el Distrito Metropolitano de Quito ha sido enfrentado solo parcialmente, enfocándose las acciones de las autoridades municipales en la recolección, transporte y disposición final, y para los generadores en el único interés de deshacerse de los desechos desde sus hogares, empresas y oficinas. No se han hecho esfuerzos institucionales ni se han puesto en marcha políticas encaminadas hacia una gestión integral de los residuos, donde se requiere la activa participación desde la generación hasta la disposición final. Por tanto, este proceso en el tiempo puede presentar problemas de sustentabilidad tomando en cuenta una creciente generación de desechos, ligada al crecimiento poblacional.

Provedor de dados: 77
Autores: Algieri,Rubén D; Ferrante,María Soledad; Pró,Eduardo.
Hace más de un siglo que se llevan adelante constantes discusiones internacionales para lograr unificar criterios respecto al lenguaje universal en Anatomía, buscando priorizar básicamente un término sobre otros equivalentes, mediante la elección de una nominación única para designar un solo concepto. En el último esfuerzo por consensuar los términos anatómicos, se creó la "Terminología Anatómica Internacional" (TAI) que actualmente ha desplazado a la anteriormente llamada "Nómina Anatómica". Estudio estadístico retrospectivo a través de una encuesta anónima a 96 médicos especialistas en Cirugía General que se realizó en la III Cátedra de Anatomía de la Facultad de Medicina de la Universidad de Buenos Aires, durante el período de mayo/2005 a mayo/2006.

Análisis económico de la “bio-carbonización” como práctica de manejo agrícola
Provedor de dados: 31
Autores: Ramirez,   Juan Andres; Rosales Alvarez,   Ramon.
Las altas concentraciones de gases de efecto invernadero, específicamente CO2, han sido señaladas como la principal causa del cambio climático. La adopción de prácticas agrícolas capaces de incrementar el contenido de carbono en el suelo, ha sido propuesta como una estrategia de bajo costo y disponibilidad inmediata para enfrentar este fenómeno. La Bio-carbonización es una de estas prácticas agrícolas, la cual implica la aplicación de carbón vegetal al suelo, de modo que el carbono queda capturado en una forma altamente recalcitrante al tiempo que se mejora la calidad del suelo. Este artículo es el primero en evaluar la viabilidad financiera y considerar algunos de los efectos económicos de la práctica, estimados para una finca tipo en la altillanura...

Tanto la globalización, la revolución tecnológica y del conocimiento, así como la crisis internacional de la década de los años 80, han sido elementos importantes que han determinado un desigual desempeño económico de América Latina durante los últimos 50 años. Fuertes diferencias en el nivel de renta demuestran la necesidad de estudiar a fondo las conclusiones de las distintas teorías de crecimiento económico, acompañadas de un desarrollo social.  En el Ecuador, ciertas provincias han demostrado una capacidad de autogestión que otras provincias no logran conseguir, y se debe en gran parte a la capacidad de generación de recursos dentro de cada una de ellas, en detrimento de aquellas que únicamente se limitan a recibir la proporción del presupuesto...

Autores: Díaz, M.V.
Nutritional condition studies allow the assessment of physiological state of each larva and thus, the establishment of favourable nursery areas which provide better survival and growth. In the present work, morphometrical, histological and biochemical techniques were employed to assess nutritional condition of anchovy, Engraulis anchoita, larvae captured in the Argentine Sea. Its results were complemented with oceanographic data and information about zooplankton abundances, both prey and predators of anchovy larvae. Anchovy larvae abundance and distribution would be mainly determined by physico-chemical variables. Even though no significant differences were found in larval nutritional condition among the studied areas, larval condition was slightly better...

Durante la reproducción de camarones peneidos en cautiverio se ha observado que las hembras, a pesar de encontrarse bajo las mismas condiciones de maduración y de que provengan de una población homogénea en cuanto a edad y tamaño, presentan un diferente potencial reproductivo. Esto es, se ha observado que un alto porcentaje (75%) de hembras no desova o produce desoves no viables, mientras que un bajo porcentaje de hembras (25%) tienen la capacidad de desovar múltiples veces, produciendo estas la mayoría (50% -70%) de nauplios. Dado que el mantener en producción hembras con nulo o bajo desempeño reproductivo implica altos costos para los productores (alimento y espacio), se ha sugerido usar sólo múltiples desovadoras para incrementar el rendimiento por...

Pecan production is one of the most important crops in our country. It not only has an economical capacity as a generator of foreign currency, but also for the social context in which it develops its production. Most of the pecan growers have small sized orchards, but at the same time, there are few pecan growers with large sized orchards that use modern technology. The objective of this study is to present a SWOT analysis of the pecan system and to describe the contexts in which it is produced and commercialized, as well as the main characteristics and problems that appear in pecan production, as well as the prediction of its future under current production and management conditions.

Análisis morfológico de huevos de Triatoma barberi Usinger(Hemiptera: Reduviidae)
Provedor de dados: 82
Autores: Evangelista-Martínez,Zahaed; Imbert-Palafox,José L; Becerril-Flores,Marco A; Gómez-Gómez,Juan V.
Triatoma barberi Usinger is a widely recognized vector of the protozoa Trypanosoma cruzi. The determination of its presence in the rural houses is made by direct observation of adults, nymphs, exuviae or eggs. For this reason, egg structural characteristics could facilitate the differentiation and identification of species that inhabit such environments. In here, the morphologic characteristics of eggs of T. barberi are described and analyzed with special attention to the anterior pole of the egg. The structural analysis of eggs by scanning electron microscopy (SEM) showed the presence of a wide and rough chorion edge, which contain aeropyles and micropyles. A deep spermatic canal between the endochorion and exochorion, and a trabecular network in the...

Provedor de dados: 66
Autores: Mambrín,Mónica V.; Avanza,María M.; Ferrucci,María S.
Aunque Grewioideae es conocida como la única subfamilia estenopalínica de Malvaceae, los análisis de polen publicados sugieren una variación morfológica. Para comprobar si la variación estructural podría tener valor taxonómico, la morfología del polen de 16 especies de los géneros Corchorus, Heliocarpus, Luehea, Mollia y Triumfetta (Malvaceae, Grewioideae) distribuidas en la región austral de América del Sur fue analizada con microscopía óptica y electrónica de barrido. Los granos de polen son 3-zonocolporados, isopolares, radiosimétricos, subesferoidales a prolatos y de tamaño mediano a grande. La escultura de la exina varía desde un birretículo con perforaciones en el lumen a un tectum densamente rugulado o microrreticulado. Los caracteres morfológicos...

Autores: Lachaud Toussaint, James.
En las últimas dos décadas, muchas son las instituciones, internacionales y nacionales, que trabajan en Haití en la planificación familiar, ofreciendo a la población haitiana, y específicamente las mujeres en edad de reproducción, diferentes servicios de salud reproductiva y servicios anticonceptivos. Sin embargo, el nivel de prevalencia de uso de método anticonceptivo sigue aún muy bajo y el nivel de necesidades no satisfechas de anticoncepción lo más alto de la región. Es así que se hace un análisis-empírico que permita entender el comportamiento reproductivo de las mujeres respecto a los servicios anticonceptivos en Haití en términos de NNSA, a partir de los factores determinantes, e integrando el efecto de selección vía en el no uso general.

Deutschland ist nicht nur größter Absatzmarkt, sondern auch größter Produzent von Bio-Produkten in Europa. Trotzdem hat der deutsche Handel im Wirtschaftsjahr 2009/2010 je nach Produkt 2 bis 95 Prozent der abgesetzten Produkte, die auch von deutschen Erzeugern hätten produziert werden können, importiert. Dies zeigt dieses Projekt, welches Befragungsergebnisse, Haushaltspaneldaten, Produktions- und Flächendaten sowie Export- und Importmengen zusammengeführt und analysiert hat.  Ein überraschendes Ergebnis war der niedrige Importanteil von Getreide mit 15 Prozent. Von Weizen allerdings kamen 21 Prozent der Partien aus dem Ausland. Der Anteil variiert je nach Menge und Qualität der deutschen Ernte, jedoch besteht in Rumänien, Russland und der Slowakei noch...

Analyse des Determinants des Exportations Beninoises de Noix D'Anacarde
Provedor de dados: 31
Autores: Adegbola,   Patrice Ygue; Zinsou,   Jacques.
La dépendance du Bénin d’une seule culture d’exportation a jusqu’ici fragilisé son économie. La filière cajou apparaît comme l’une des plus intéressantes à développer suite à la crise cotonnière. Cet article examine les facteurs qui expliquent les exportations des noix d'anacarde au Bénin et leurs effets. Pour ce faire, la méthode d’estimation des Modèles à Correction d’Erreur (ECM) est utilisée. Les résultats révèlent que l’augmentation de la production et la pratique d’un prix relativement bas permettra au Bénin d’acroitre significativement le niveau actuel de ses exportations de noix cajou à court et à long terme. Mots clés : Noix de cajou, Exportations, Modèle à correction d’erreur, Bénin.

Scientific report of FEP cod study carried out in Eastern English Channet and southern North sea. This study as been driven by North, Pas-de-Calais/Picardie French Fishery Committee and Ifremer was technical expert (methodology, analysis). From October 2008 to May 20009, 92 trips corresponding to 249 days at sea were observed. Discarded part is globally important with 75% in weight and 80% in number for the observed trips, but the discards are very variable during time, even in the same Métier. The raising of the catches to the fleet using a two levels estimator, by quarter, by Métier and by ICES division, gives low precise estimations with CVs meanly higher than 20%. These results are nevertheless plausible if we compare with elevation of landings which...

Analyse des stratégies de contrôle dans une pêcherie gérée par l’effort de pêche : le cas de la pêcherie de coquilles Saint-Jacques de la baie de Saint-Brieuc
Provedor de dados: 5
Autores: Le Gallic, Bertrand; Fifas, Spyros; Lesueur, Marie; Roncin, Nicolas; Ropars-collet, Carole.
Since a report by the European Court of Auditor in December 2007, EU officials have been suggesting that the failure of the Common Fisheries Policy (CFP) results from too much non compliance and a weak and inefficient enforcement system. As a result, a stakeholder consultation was organised EU-wide, and a new control regulation has been presented by the European Commission in autumn 2008. The objective of the paper is to discuss the reality and the scope of this assertion in the situation of a French coastal fishery managed through effort control (the Saint-Brieuc scallop fishery). Key outlines of the French control strategy are presented for the first time, based on an extensive work with the key stakeholders (national and regional administrations and...

Analyse des verbraucherorientierten Qualitätsurteils mittels assoziativer Verfahren am Beispiel von Schweinefleisch und Kartoffeln
Provedor de dados: 31
Autores: Bruhn,   Maike; Grebitus,   Carola.
Consumers’ quality judgement depends on their knowledge concerning certain quality attributes. Against this background this paper presents the results of a consumer survey conducted in 2004. We focus on measuring consumers’ cognitive structures regarding pork and potatoes. On this account we apply a free-association technique and a variation of concept mapping. Our analysis shows that consumers’ cognitive structures are quite complex and heterogeneous. Product characteristics such as ‘taste’ and ‘fat content’ dominate consumers’ knowledge. To predict the eating quality of pork consumers prefer intrinsic quality cues. In contrast to that extrinsic quality cues are used to predict the origin of the given product. With regard to potatoes the intrinsic quality...

In addition to the impact on climate change resulting from the use of non renewable resources [1], the depletion of existing fossil fuel sources is inevitable. A major change of strategy is required. This article presents an analysis of a Flax fibre/PLLA biocomposite life cycle compared to common glass fibre reinforced polyester composites from manufacturing to mechanical design and end-of-life. Environmental impacts have been assessed by Standardized method called Life Cycle Analysis (ISO 14044). Flax fibre/PLLA biocomposites manufactured by film stacking have, for similar mass, tensile modulus close to that of Glass/Polyester. Besides being compostable at end of life, biocomposites have been proved to be recyclable which makes it possible to keep the...

Autores: Bouchoucha, Marc; Andral, Bruno.
La mesure des contaminants chimiques directement dans la colonne d’eau est coûteuse, difficilement interprétable et peu applicable à de nombreux échantillons prélevés le long d’un important linéaire côtier. Pour surmonter ces difficultés, les contaminants peuvent être mesurés dans la chair de bioaccumulateurs naturels tels les moules. Depuis 1996, le réseau RINBIO évalue les niveaux de contamination chimique à l’échelle de la façade méditerranéenne en utilisant une technique de caging de moules. Or, les caractéristiques du capteur représenté par les moules varient en fonction du milieu et notamment de ses capacités trophiques.

Analysing agricultural productivity growth in a framework of institutional quality
Provedor de dados: 31
Autores: Ahmed,   Mirza Nomman; Maas,   Sarah; Schmitz,   P. Michael.
This paper addresses the question whether the institutional environment of transition countries in Eastern Europe affects productivity growth in the agricultural sector. Situated in a neoclassical growth framework, a dynamic panel model for the period 1996-2005 provides evidence that poor institutional quality leads to a slowdown in agricultural productivity growth. Productivity growth is limited by a high degree of corruption, which is of particular importance given that corruption has been proven to be most prevalent in Eastern European countries. Moreover, agricultural productivity in countries where privatisation and transferability of land is restricted is found to grow at a slower rate than countries supporting market-oriented land reforms....

Analysing Government Decision Making in the South African Biofuels Industry: A Game Theoretic Approach
Provedor de dados: 31
Autores: Funke,   Thomas; Klein,   Peter G.
The production of biofuels in many countries is largely driven by the government strategy and incentives that are in place. In South Africa the first round of the development of such a draft strategy took place in 2005 while the official stance on biofuels was finalized in December of 2007. During the policy development process various governmental departments had strategic goals and targets that they all were required to achieve. The achievement of these strategic targets and goals is also risky and the various departments that have some form of involvement in the biofuels industry need to decide on how much risk they are willing to take. This article sketches the game that the various governmental departments played as well as the risks that they were...

Autores: Ottone,Nicolás Ernesto; Prum,Natalia; Dominguez,Mario; Blasi,Esteban; Medan,Carlos; Shinzato,Sergio; Finkelstein,Diana; Bertone,Vicente Hugo.
The classic description of the hand's superficial palmar arch is based on the anastomosis among the ulnar and radiopalmar arteries, a branch of the radial artery. However, the arch formation is highly variable regarding the size of the arteries that make it up and due to the existence of branches coming from other arteries and adding up as tributary to it. The objective of this paper is to classify these possible varieties, to define the formation of the arch, the reasons for its variable arrangement and the importance of its clinical and surgical applications. 86 formalized hands were dissected at 40%. There is prevalence concerning the size of the ulnar artery, with or without an arch. The anatomic knowledge of the variability in the arch formation...

Autores: da Mata,João Roberto; da Mata,Fabiana Ribe; Aversi-Ferreira,Tales Alexandre.
Inadequate ossification of the interparietal region induces the appearance of interparietal and wormian bones, also associated with genetic factors. The formation of the interparietal bone depends on the separation of the intermediate segment from the lateral plate by the transverse occipital suture, which means that this bone is formed by the medial and lateral plates. Wormian interparietal bones or epactal bones are located within the interparietal region, being single or multiple, and are located in the upper central region of the interparietal region, the sutural bones, however, are formed from additional ossification centers that can occur in near sutures. The aim of this work was to macroscopically evaluated the presence of changes in the structure...

Analysis of chlorophyll fluorescence reveals stage specific patterns of chloroplast-containing cells during Arabidopsis embryogenesis
Provedor de dados: 48
Autores: TEJOS,RICARDO I; MERCADO,ANA V; MEISEL,LEE A.
The basic body plan of a plant is established early in embryogenesis when cells differentiate, giving rise to the apical and basal regions of the embryo. Using chlorophyll fluorescence as a marker for chloroplasts, we have detected specific patterns of chloroplast-containing cells at specific stages of embryogenesis. Non-randomly distributed chloroplast-containing cells are seen as early as the globular stage of embryogenesis in Arabidopsis. In the heart stage of embryogenesis, chloroplast containing cells are detected in epidermal cells as well as a central region of the heart stage embryo, forming a triangular septum of chloroplast-containing cells that divides the embryo into three equal sectors. Torpedo stage embryos have chloroplast-containing...

Provedor de dados: 5
Autores: Renault, Tristan; Moreau, Pierrick; Faury, Nicole; Pepin, Jean-francois; Segarra, Amelie; Webb, Stephen.
Although there are a number of ostreid herpesvirus 1 (OsHV-1) variants, it is expected that the true diversity of this virus will be known only after the analysis of significantly more data. To this end, we analyzed 72 OsHV-1 "specimens" collected mainly in France over an 18-year period, from 1993 to 2010. Additional samples were also collected in Ireland, the United States, China, Japan, and New Zealand. Three virus genome regions (open reading frame 4 [ORF4], ORF35, -36, -37, and -38, and ORF42 and -43) were selected for PCR analysis and sequencing. Although ORF4 appeared to be the most polymorphic genome area, distinguishing several genogroups, ORF35, -36, -37, and -38 and ORF42 and -43 also showed variations useful in grouping subpopulations of this...

Provedor de dados: 31
Autores: Shinoj,   P.; Mathur,   V.C.
India is the largest producer, consumer, and exporter of spices in the world. The demand scenario for major spices in India has been comprehensively examined in the study. The shift in preferences of domestic consumers for food items, increasing urbanization and rising incomes, altered demographic and social factors and the changes in productivity of spices have brought about changes in the pattern of their consumption and demand. A two-stage budgeting framework, which is a recent development in the theory, of demand with quadratic terms of total expenditure / food expenditure and is an appropriate technique for computing the expenditure elasticities, has been employed to work out the expenditure elasticities for spices in India. The resultant expenditure...

Analysis of dog and cat population submitted to vaccination campaigns against rabies in a small city from Brazil
Provedor de dados: 195
Autores: Babboni, S. D.; Fornazari, F.; Gonzalez, G. K.; Victoria, C.; Modolo, J. R.
In many developing countries domestic dogs and cats are the most important transmitters of rabies to men. The annual vaccination constitutes an important preventive activity, and the knowledge of animal population profile can assist future prophylatic programs, not just for rabies but also for other infectious diseases and social problems involving dogs and cats. In most Brazilian cities there is no census that can provide these data. One alternative, although limited, is to collect information from the vaccination campaign itself, realized by the public service. The present study aimed to analyze: the number of vaccinated dogs and cats in a small Brazilian city; their sex and reproductive status; and evaluate if there was a decrease in vaccinated animals...

Background: In both USA and Europe operate companies selling Direct-to-consumer genetic tests (DTC). These tests are offered to healthy people aiming to identify predispositions to complex diseases and to take preventive measures. Several DTC-nutrigenetic tests (DNTs) are available on the market. They propose the definition of a personalized diet, on the basis of the investigated genetic variants, which would reduce the risk of developing those diseases which have been associated to specific genetic markers. However, the risk/benefit balance of exposing unselected population to genetic testing without any medical surveillance is far from be established. Furthermore, it lacks an accepted procedure to select which genetic markers needs to be investigated, to...

Analysis of Environmental and Economic Efficiency: Application of the Overseer model and simulated data
Provedor de dados: 31
Autores: Ramilan,   Thiagarajah; Scrimgeour,   Frank G.; Marsh,   Dan.
New Zealand’s success in raising agricultural productivity has been accompanied by higher input use, leading to adverse effects on the environment. Until recently, analysis of farm performance has tended to ignore such negative externalities. The current emphasis on environmental issues has led dairy farmers to target improvements in both environmental performance and productivity. Therefore measuring the environmental performance of farms and integrating this information into farm productivity calculations should assist informed policy decisions which promote sustainable development. However this is a challenging process since conventional environmental efficiency measures are usually based on simple input and output flows but nitrogen discharge is a...

Analysis of Expected Price Dynamics Between Fluid Milk Futures Contracts and Cash Prices for Fluid Milk
Provedor de dados: 31
Autores: Fortenbery,   T. Randall; Cropp,   Robert A.; Zapata,   Hector O.
Future contracts for fluid milk began trading in late 1995 and early 1996. This paper investigates the potential use of fluid milk futures contracts as hedge vehicles for dairy producers in the Upper Midwest and California markets. This is done by developing simulated futures prices for the period 1988 to 1995. The simulated futures prices are used to estimate basis relationships between cash and futures prices for the markets considered. Results suggest that the fluid milk futures contracts could be used to reduce market price risk for producers in the Upper Midwest. Results were less conclusive for California producers.

Analysis of Flue-cured Tobacco Supply Elasticity in Zimbabwe 1980-2010: An Error Correction Model Approach
Provedor de dados: 31
Autores: Pfumayaramba,   Tichaona.
Flue cured tobacco has been an important crop for the Zimbabwean economy historically in terms of foreign currency earnings and employment creation. Between 1980 and 2000, there is a general increase in tobacco output, followed by a sharp decline from 2001 up to 2008 and then output starts to increase again. Flue cured tobacco output as measured by the quantity that is delivered to the auction floors is used to estimate supply elasticity. The objective is to determine if flue-cured tobacco supply is price elastic and whether price incentives alone will boost supply in the short -run. Time series data on flue cured tobacco output, prices, production costs, prices of major competing crops, the exchange rates and inflation are analysed to model the price...

Analysis of genetic diversity in Argentinian heterotic maize populations using molecular markers
Provedor de dados: 118
Autores: Morales,Marcelo; Decker,Viviana; Ornella,Leonardo.
Over the past three decades, traditional Argentinean Orange Flint maize cultivars have been replaced by the higher yielding U.S. Yellow Dent germplasms. However, fint cultivars are potentially resistant to biotic and/or abiotic stress. Thus, knowledge of genetic diversity and relationships among fint inbred lines would help reduce genetic vulnerability and broaden the genetic base of crops in national improvement programs. In this study, we report the analysis of 25 inbred Orange Flint germplasms and one dent using 21 microsatellite markers or Simple Sequence Repeats (SSR). The aim was to assess genetic diversity among these accessions and evaluate the usefulness of SSR markers for defning heterotic groups in temperate germplasm. Genetic diversity values...

Provedor de dados: 115
Autores: Shahidullah,S. M.; Hanafi,M. M.; Ashrafuzzaman,M.; Uddin,M. K.; Razi-Ismail,M.
Aromatic rices (Oryza sativa L.) normally produce enormous spikelets of low grain weight resulting low yield. Grain weight and grain density are the vital indicators of grain filling and mainly dependent on genetic make-up. Detail study of grain density and yield components of aromatic rice is a crucial need for yield improvement. An experiment was conducted with 40 rice genotypes to assess the grain density of aromatic rices and to observe the relationships of different grain categories with yield characters. The percentage of high density grains, good grains, average grains, poor grains, partially filled grains, spikelet sterility, and thousand grain weight were found to vary in a great extent. Maximum 50 % high density grain was harvested in BR39 and a...

The market of wooden beds in the U.S. has been flooded with imports from China and Vietnam in recent years. Static and dynamic Almost Ideal Demand System models are used to assess the import demand for wooden beds from the top seven supplying countries. The analyses reveal that the antidumping investigation on China has some temporary trade depression effect on China, but trade diversion occur  to Vietnam, Indonesia, Canada, and Brazil. The formal implementation of antidumping duties since 2005 has not shown any significant effect on the trade pattern. U.S. consumers spend more on beds from newly industrialized countries and there are moderate degrees of substitution among wooden beds from most countries.

Irrigation development is a gateway to increased agricultural, water and land productivity, increased household and national food security. However, irrigation development has been a major challenge in many developing countries, including Zimbabwe. The launch of the Fast Track Land Reform Programme (FTLRP) in 2003 ushered in new unskilled cadres and this was followed by a reduction in area developed for irrigation from 200,000ha to approximately 120,000ha. This was due to thefts, dilapidation, and vandalism of irrigation infrastructure. The government made efforts to develop and bring back the 200,000ha into operational, but little has been achieved. To assess irrigation development post FTLRP, a case study was done in Goromonzi District. Using a Trend...

Results from continuous tracking of consumer confidence and media coverage of food safety events over a 67 week period between May 2008 and August 2009 are reported.  An ordered probit model is used to test the hypothesis that media coverage of food safety events affects consumer confidence in the safety of the U.S. food system. The results show that media coverage significantly and negatively affected consumer confidence in the safety of nation’s food supply during the sample period. Socioeconomic and demographic factors such as geographic region, use of media source, household size, age, ethnicity, education, and gender also had significant affects on consumer confidence in the safety of United States food supply.

Costly investments in storage and transport of onion bulbs makes it increasingly important to identify cultivars with the best chance of long-term storage. This paper discusses our own and other researchers' results and laboratory procedures on onion's pungency, soluble solids, dry matter, respiration rate, carbohydrates and catabolism-related enzymes under different storage conditions. The variability in parameters such as carbohydrate composition, pungency, soluble solids and soluble uronic acid concentration in water is growth dependent, and defines the quality of onion bulbs at harvest time. During storage, these parameters can be modified by environmental conditions, presence of pathogens or termination of dormancy. Under postharvest conditions,...

The strategy is based upon the idea that traditionally cultivated crops have been used safely for many years, thus every divergence within the compounds of a GMP in contrast to its non-GMP counterpart could refer to a risk and has to be further analysed.&amp;#xd;&amp;#xa;&amp;#xd;&amp;#xa;The BioOK company offers the opportunity to analyse very different aspects from the ERA of GMPs in one hand. Beside toxicological analysis and the determination of environmental effects via soil analysis, we can look into several plant metabolites to identify...

Autores: Marinkovic,   Slaoana; Nedic,   Nebojsa.
The study researched the costs and returns on typical small beekeeping farms from five districts in Serbia. On the basis of the field research, data on the number of beehives, type of product, volume of production per beehive and values per measurement unit were collected. In order to demonstrate the competitiveness of various agricultural products, analysis of the available data was performed using analytical calculations. According to the analysis, the labour costs comprise about 49.65%to 64.15%of the variable costs on beekeeping farms in the Raška and Šumadija districts, respectively. Production is most economical on the bee farm in the district of Srem, where every dinar spent in production creates a value of 2.22 dinars, while the farm from the...

Many methods are available to analyze rank ordered data. We used a spectral density analysis to identify most preferred options of Formosan Subterranean Termites (FST) control as ranked by Louisiana homeowners. Respondents are asked to rank four termite control methods form the most preferred option to the least preferred option. Spectral analysis of both complete and partial ranked data indicates that the most preferred termite control choice is a relatively cheap ($0.13 per square foot) option of a Liquid treatment.

Analysis of the association between spawning time QTL markers and the biannual spawning behavior in rainbow trout (Oncorhynchus mykiss)
Provedor de dados: 74
Autores: Colihueque,Nelson; Cárdenas,Rosy; Ramírez,Lorena; Estay,Francisco; Araneda,Cristian.
The rainbow trout is a salmonid fish that occasionally exhibits broodstocks with biannual spawning behavior, a phenomenon known as a double annual reproductive cycle (DARC). Spawning time quantitative trait loci (SPT-QTLs) affect the time of the year that female rainbow trout spawn and may influence expression of the DARC trait. In this study, microsatellite markers linked and unlinked to SPT-QTLs were genotyped to investigate the underlying genetics of this trait. SPT-QTLs influenced the DARC trait since in two case-control comparisons three linked markers (OmyFGT12TUF, One3ASC and One19ASC) had significant levels of allelic frequency differentiation and marker-character association. Furthermore, alleles of One3ASC and One19ASC had significantly higher...

Autores: Gebeltova,   Zdenka.
The paper analyzes the reasons for the prices of milk and milk products in the Czech Republic for the period 2008 – 2009. In January 2008, the purchase price of raw milk was 10.08 CZK/l, and in the subsequent period it began to decline. At the end of 2008, the price was more than 3 crowns lower, and still the decrease continued. The research determined that the essential reason for the price fluctuations is the impact of the economic crisis. A substantial portion of the article was devoted to analyzing the behavior of supermarket chains toward their suppliers. It was discovered that even here there is a lot of room for the creation of pricing policy. Margin trading networks up to 25% of the delivered goods.

Echolocation is characteristic of bats of the suborder Microchiroptera. Though recent studies of echolocation calis in Latin America have generated significant advances in knowledge about distribution, habitat use and ecology of bats, the recording and analysis of bat calis is barely known in Chile. As a first step in studies on the ecology of the endemic Chilean myotis bat (Myotis chiloensis), we carried out morphometric measures and analyzed echolocation calis in a rural site near Pucón (39°15'S 17°W) in the Araucanía Region of southern Chile. During January 2009, we obtained 22 records from captured and 75 records from fiying individuals. The analysis of calis in searching phase showed that the terminal frequency for this species is 43.4 ±1.2 kHz, with...

ANALYSIS OF THE EFFECTS IN ITALY OF ALTERNATIVE HYPOTHESES OF REGIONALIZATION OF THE SINGLE PAYMENT SCHEME
Provedor de dados: 31
Autores: Pupo D'Andrea,   Maria Rosaria.
The Fischler reform of the CAP deepened the decoupling process of agricultural support started with the 1992 reform, introducing the Single Payment Scheme (SPS). Two models could be used to apply the SPS: in the historic model payments are based on individual reference amounts; in the regional model payments are based on regional reference amounts. Italy chose to apply the historic model, thus “freezing” the distribution of support to farms at the historic reference level. The recent Proposal on the Health Check of the CAP envisaged Member States being allowed to adjust their model towards a flatter rate of the SPS from 2010, a move that could become compulsory for Member States after 2013. The paper analyses the effects at territorial and farm level of...

Analysis of the Governance Structure used by Eksteenskull Raisin Producers: Is there a need for more Vertical Coordination?
Provedor de dados: 31
Autores: Jordaan,   Henry; Grove,   Bennie.
Eksteenskuil raisin producers are a group of emerging raisin producers who are successfully participating in a sophisticated value chain. They collectively export their raisins through the fairtrade initiative. Emerging farmers typically face high levels of transaction cost. The high levels of transaction cost in combination with the changing nature of the marketing environment, suggest that the different modes with which transactions can be coordinated need to be assessed in order to identify that mode that would minimise the transaction cost. The aim of this paper is to investigate the governance structures that are employed by Eksteenskuil raisin producers in order to determine whether an alternative may not contribute to reducing transaction costs...

Analysis of the Influence of Hydrostatic Stress on the Behaviour of an Adhesive in a Bonded Assembly
Provedor de dados: 5
Autores: Cognard, J. Y.; Creac'Hcadec, R.; Maurice, J.; Davies, Peter; Peleau, Michel; Da Silva, L. F. M.
Generally, adhesives are viscoelastic-plastic materials, for which the development of viscosity and plasticity varies depending on the type of adhesive and the stress state. Various models exist to represent the yield surface, or the so-called elastic limit, taking into account the two stress invariants, hydrostatic stress and von Mises equivalent stress. Moreover, to develop precise pressure-dependent constitutive models, it is necessary to have a large experimental database in order to accurately represent the adhesive strains which are strongly dependent on the tensile-shear loading combination. Under quasi-static loadings, for a given strain rate range viscous effects can be neglected, but only a few experimental results are available to model the...

Autores: Krejci,   Igor; Voriskova,   Andrea.
The paper deals with the analysis of a method used by the Czech Government and the Ministry for Regional Development to select regions with concentrated state aid. It contains a comparison with several different basic methods of multi-criteria decision-making (MCDM). The analysis focuses on a mathematical algorithm of the established MCDM method and does not consider validity of any selected socioeconomic criteria and their weights. Both the strengths and weaknesses of the used MCDM method are presented. The paper includes a simple proposal of the modification of the examined method that will prevent incorrect data normalisation used for region’s evaluation before revision in 2010. Data used for all calculations were obtained from the Ministry for Regional...

The subject of the relationship between state budget and trade balance is important as economic subject, not only at the level of developing countries, but also at of advanced ones, too. Such importance emerged clearly when 1980s witnessed in United States of America a deficit in both state budget and trade balance, which was called at that time as the twin or dual deficit. We can say that the analysis of relationship between state budget and trade balance states the extent of mutual effect between financial and trade policies of any economy, namely; any change in the outcome of either one may affect the other in the same degree. To put in other words, the instruments of financial policy represented by total incomes and total expenditures can affect the...

We analyzed the SLC4A1 gene in three Mexican patients with Hereditary Spherocytosis (HS). The promoter and all 20 exons were investigated through heteroduplex analysis and DNA sequencing. No DNA changes were detected in one of the three patients. Two well-known polymorphisms, Memphis I and the Diego-a blood group, were detected in another one. In the third, the HS phenotype could be explained by the novel 1885_1888dupCCGG mutation found in heterozygosis. This frameshift mutation is predicted to result in a truncated and unstable protein lacking normal functions.

Potential ways to address the issues that relate to the techniques for analyzing food and environmental samples for the presence of enteric viruses are discussed. It is not the authors' remit to produce or recommend standard or reference methods but to address specific issues in the analytical procedures. Foods of primary importance are bivalve molluscs, particularly, oysters, clams, and mussels; salad crops such as lettuce, green onions and other greens; and soft fruits such as raspberries and strawberries. All types of water, not only drinking water but also recreational water (fresh, marine, and swimming pool), river water (irrigation water), raw and treated sewage are potential vehicles for virus transmission. Well over 100 different enteric viruses...

Analyzing Differences in Rural Hospital Efficiency: A Data Envelopment Analysis Approach
Provedor de dados: 31
Autores: Nedelea,   I. Cristian; Fannin,   James Matthew; Barnes,   James N.
This study analyzes difference in efficiency among the U.S. rural hospitals using a two-stage, semi-parametric approach. Data Envelopment Analysis is used in the first stage to calculate cost, technical and allocative efficiencies of Critical Access Hospitals (CAH) and non-CAH rural hospitals. Following Simar and Wilson (2007), bootstrapped truncated regressions are used in the second stage to infer on relationship between the cost, technical and allocative inefficiencies of hospitals and some environmental variables. The estimated results show that CAHs are less cost, technical and allocative efficient than non-CAH rural hospitals. The results also show that Medicare cost-based reimbursement for CAHs has a negative effect on the efficiency of these...

Analyzing Large Paleoclimate Datasets: Implications for Past and Future Climate Change.
Provedor de dados: 5
Autores: Shakun, Jeremy D.
This dissertation presents the results of statistical analyses of large climate datasets from two time intervals – the 20th century instrumental record and the proxy record of the last deglaciation – in order to understand the forcings and mechanisms of past climate variability. A longstanding question in climate dynamics concerns the origin of Pacific decadal variability (PDV). This issue is addressed by calculating the Southern Hemisphere equivalent of the Pacific Decadal Oscillation (PDO) index from Pacific sea surface temperature (SST) anomalies over the 20th century, which is found to be similar to its Northern Hemisphere counterpart. The Northern and Southern PDO indices both exhibit pronounced seasonality in autocorrelation with interannual...

Analyzing local image statistics via maximum-entropy constructions
Provedor de dados: 17
Autores: Jonathan D. Victor; Daniel J. Thengone; Mary M. Conte.
Because the space of signals that the visual system encounters is high-dimensional, investigations of visual processing and perception must utilize a sampling strategy.  One kind of approach begins with a class of models for input-output relations, and then chooses a stimulus ensemble such as white noise that enables efficient determination of model parameters.  A second kind of approach begins with the explicit recognition that it is important to understand the visual system in the context of the inputs under which it functions and evolves; this motivates the use of naturalistic stimulus ensembles.  Neither approach alone is sufficient: models built from ensembles such as white noise provide only a fair account of responses to natural scenes, and the...

Analyzing supply response of fruit tree products in Tunisia: The case of peaches
Provedor de dados: 31
Autores: Laajimi,   Abderraouf; Guesmi,   Anis; Mahfoudhi,   A.; Dhehibi,   Boubaker.
In Tunisia, peaches have a significant place in the fruit tree sector. Planted areas have  been expanding ever since the eighties as a result of irrigation water extension and the  use of better yielding varieties. These factors resulted in high production levels and fruit exports  thereof.  However,  important  seasonal  and  annual  variation  of  fruit  supplies continues to characterize prices at both wholesale and consumption levels. To study the  response  of  peach  production  an  econometric  model  was  developed. Modelling  was carried out in two stages. First area variation was explained through new plantings and removals and second yield variation was analyzed. The methodological approach followed takes into account the characteristics and...

Analyzing the Determinants of Technical Efficiency Among Traditional Dairy Farms in Wisconsin: A Quantile Regression Approach
Provedor de dados: 31
Autores: Chidmi,   Benaissa; Solis,   Daniel; Funtanilla,   Margil; Cabrera,   Victor E.
This study analyzes the determinants of TE among traditional dairy farms in the State of Wisconsin taking into account dairy farms’ heterogeneity. To do so, we first estimate a production frontier and the level of TE using the SPF framework. Then we analyze the determinants of TI using a quantile regression analysis. The results indicate that the determinants of TE affect in very specific ways farmers with different levels of TE. This result confirms our hypothesis on the importance of controlling for farm heterogeneity when analyzing the determinants of TE. This issue is also important from an empirical point of view. Policy makers could improve the effectiveness of their work by targeting specific agricultural services and aid designed for farmers with...

Analyzing the Effects of Weather and Biotechnology Adoption on Corn Yields and Crop Insurance Performance in the U.S. Corn Belt
Provedor de dados: 31
Autores: Vado,   Ligia; Goodwin,   Barry K.
Favorable weather and the adoption of Genetically Modified (GM) corn hybrids are often argued to be factors that explain recent corn yield increases and risk reduction in the U.S. Corn Belt. The focus of this analysis is to determine whether favorable weather is the main factor explaining increased and more stable yields or if biotechnology adoption is the more relevant driving force. The hypothesis that recent biotechnology advances have increased yields and reduced risks by making corn more resistant to pests, pesticides, and/or drought is tested. Fixed effects models of yields and crop insurance losses as functions of weather variables and genetically modified corn adoption rates are estimated taking into account the non-linear agronomic response of...

Provedor de dados: 31
Autores: Birur,   Dileep K.; Beach,   Robert H.
As the biofuels are emerging as promising alternative transportation fuels across the world, they also offer huge potential for international trade in biofuels. A number of trade barriers such as import tariffs and domestic support have limited the scope for trade in biofuels. The purpose of this study is to analyze the implications of U.S. biofuel mandates, subsidies and import tariffs on global trade and welfare. We utilize the GTAP-BIO model, which was developed as a customized version of the Global Trade Analysis Project (GTAP) model capable of analyzing domestic and trade policy issues associated with biofuels (Birur, 2010). We supplement this model with updated and detailed sectoral level information on feedstock crops, different types of first and...

Anatomical Dissection: A Positive Experiencen for Venezuelan First Year Medical Students
Provedor de dados: 77
Autores: Romero Reverón,Rafael.
An anonymous survey was handed out to 616 first year medical students of the José María Vargas School of Medicine of the Central University of Venezuela during the six academic years from 2002 and 2008, so that they answer it voluntarily after a cadaver dissection session, after the first unit of the practice syllabus of Gross Anatomy I had completed. The results of these surveys delivered to first year medical students report a positive response to their initial experience with a cadaver in the anatomical dissection room. In fact, the students described this initial experience as positive in a 52.22 %, while 34,25 % referred to it as very positive, 7.14 % as stressing and only a 1.13 % rated it as traumatic. In the case of only 13.63 % of these students...

Anatomical root variations in response to water deficit: wild and domesticated common bean (Phaseolus vulgaris L)
Provedor de dados: 48
Autores: Peña-Valdivia,Cecilia B; Sánchez-Urdaneta,Adriana B; Meza Rangel,Joel; Juárez Muñoz,Juana; García-Nava,Rodolfo; Celis Velázquez,Raquel.
Root anatomical responses to water deficit are diverse and regulation of water uptake strongly depends on plant anatomy. The ancestors of common bean (Phaseolus vulgaris L.) cultivars are the wild common beans. Because wild beans adapt and survive well in theon atural environment, it is hypothesized that wild common bean roots are less affected than those of domesticated beans at low substrate water potential (&amp;#968;W). A wild common bean accession from Chihuahua Mexico and cv. Bayomex were studied. Seedlings with a mean root length between 3 and 4 cm were maintained for 24 h in vermiculite at &amp;#968;W of -0.03 (well hydrated), -0.65, -1.48 and -2.35 MPa (partially dry). Ten anatomical characteristics of differentiation and cell division in root...

Provedor de dados: 77
Autores: Suazo Galdames,Iván; Zavando Matamala,Daniela; Smith,Ricardo Luiz.
The ossification of the intrinsic ligaments of the sphenoid bone has been reported in the literature. The presence of bony bridges by ossification of the pterygospinous and pterygoalar ligaments has clinical significance in the infratemporal fossa contents. The purpose of this study is to analyze the prevalence of ossification of these ligaments and assess morphometrically the pterygospinous (Civinini's) and pterygoalar (crotaphitico-buccinatorius) foramens. A total of 312 human skulls from the collection of Universidade Federal de São Paulo (UNIFESP) were used to assess the presence of total or partial ossification in pterygospinous (Types I and II) and pterygoalar (Types III and IV) ligaments. Of the sample, 37.18% had some degree of ossification; in...

Anatomy, histochemistry and ultrastructure of seed and somatic embryo of Acrocomia aculeata (Arecaceae)
Provedor de dados: 63
Autores: Moura,Elisa Ferreira; Ventrella,Marília Contin; Motoike,Sérgio Yoshimitsu.
Macaw palm (Acrocomia aculeata (Jacq.) Lodd. ex Mart.) is a tropical species with multiple uses, including oil supply for biodiesel production. However, structural and physiological studies of the seed are still scarce, as well as in vitro propagation techniques. The aim of this study was to characterize the anatomy, histochemistry and ultrastructure of the seed and the in vitro somatic embryo of A. aculeata, gaining insight into relationships between the post-harvest seed behavior and the somatic embryo conversion to plant. The zygotic embryo and the endosperm show high quantities of protein and lipids, stored in protein and lipid bodies, respectively. The cell wall storage polysaccharides occur in the thickened cell wall of the endosperm. The absence of...

Anbau von Wintererbsen in Rein- und Mischsaat mit Raps und Triticale bei kurzfristig variierter Intensität der Bodenbearbeitung
Provedor de dados: 21
Autores: Gronle, Annkathrin; Böhm, Herwart.
Der Anbau von Wintererbsen könnte auf Standorten, auf denen die termingerechte Aussaat von Sommererbsen aufgrund von schwierigen Bodenbedingungen problematisch ist, eine Alternative darstellen. Ein Anbau von normalblättrigen Wintererbsen-Sorten mit Mischungspartnern soll die Standfestigkeit und die Beerntbarkeit der Wintererbsen verbessern, die Unkrautunterdrückung fördern und zu einer besseren Ertragsleistung führen. Neben dem Anbausystem, wie etwa dem Mischfruchtanbau, beeinflusst insbesondere die Art und Intensität der Bodenbearbeitung das Pflanzenwachstum und folglich das Unkrautaufkommen sowie die Ertragsleistung. Ziel des Versuches war es daher, den Mischfruchtanbau von Wintererbsen in unterschiedlich intensiven Bodenbearbeitungssystemen zu...

Cropping spring barley, long varieties with vigorous growth are desired in organic farming expecting better regulation of weeds. Six old varieties were compared to three modern varieties in a field trial during 2010 and 2011 nearby Freising, Bavaria. The modern varieties were the recommended varieties for Bavaria at beginning of the trial. Higher crop yields were determined for modern varieties with limitation for one of these varieties. The malt quality of the modern varieties was considerably better than for the old varieties. Vigorous growth and plant length was higher for all and for five of the six old in comparison to modern varieties, respectively. But no differences in weed pressure could be measured due to successful mechanical weed control....

Anbauwürdigkeit von Wintererbsen - Ein Vergleich zu Sommererbsen in Rein- und Gemengesaat unter den Bedingungen des Ökologischen Landbaus
Provedor de dados: 21
Autores: Urbatzka, Peer.
Der Anbau von Sommerkörnererbsen ist im Ökologischen Landbau häufig aufgrund einer geringen Beikrautunterdrückung und daraus resultierender Druschprobleme sowie spezifischen Pilzkrankheiten schwierig. Zusätzlich wird dieser Kultur oft eine mangelnde Wettbewerbsfähigkeit gegenüber anderen Produktionsverfahren attestiert. Als Folge wurde in den letzten Jahren der An-bauumfang in der landwirtschaftlichen Praxis deutlich reduziert. Einerseits ist im ökologischen Pflanzenbau neben einer schwierigen Beikrautregulierung die Stickstoffversorgung der Fruchtfolge einer der größten Problembereiche. An-dererseits besteht in der ökologischen Tierhaltung ein großer Bedarf an ei-weißreichen Futtermitteln. Daher wurde in Rein- und Gemengesaat mit Getreide die...

Autores: Raffaele Zanoli, Raffaele; Roberta Callieris, Roberta; Simona Naspetti, Simona.
Come le aziende biologiche possono comunicare i valori etici e ambientali è stato oggetto di studio nell’ambito del progetto comunitario Core Organic – Farmer Consumer Partnership. I temi etici aggiuntivi più rilevanti e sentiti dai consumatori sono: tutela del benessere animale, salvaguardia dei prodotti locali e regionali, pagamento di prezzi equi ai produttori. Dai risultati dello studio qualitativo svolto appare che i consumatori italiani, ovunque essi consumino i prodotti bio, sono molto interessati all’origine del prodotto e preferiscono prodotti locali, in quanto ritenuti più freschi anche se non necessariamente più "genuini". La comunicazione pubblicitaria, inoltre, deve prevedere messaggi chiari, informazioni dettagliate, in particolare i...

Ancillary Benefits of Reduced Air Pollution in the United States from Moderate Greenhouse Gas Mitigation Policies in the Electricity Sector
Provedor de dados: 31
Autores: Burtraw,   Dallas; Krupnick,   Alan J.; Palmer,   Karen L.; Paul,   Anthony; Toman,   Michael; Bloyd,   Cary.
This paper considers how moderate actions to slow atmospheric accumulation of greenhouse gases from fossil fuel use also could reduce conventional air pollutants in the United States. The benefits that result would be "ancillary" to greenhouse gas abatement. Moreover, the benefits would tend to accrue locally and in the near term, while benefits from reduced climate change mostly accrue globally and over a time frame of several decades or longer. The previous literature suggests that changes in nitrogen oxides (NOx) would be the most important consequence of moderate carbon policies. We calculate these changes in a detailed electricity model linked to an integrated assessment framework to value changes in human health. A tax of $25 per metric ton of carbon...

ANDRO: An Argo-Based Deep Displacement Dataset
Provedor de dados: 5
Autores: Ollitrault, Michel; Rannou, Jean Philippe.
During the first decade of the twenty-first century, more than 6000 Argo floats have been launched over the World Ocean, gathering temperature and salinity data from the upper 2000 m, at a 10-day or so sampling period. Meanwhile their deep displacements can be used to map the ocean circulation at their drifting depth (mostly around 1000 m). A comprehensive processing of the whole Argo dataset collected prior to 1 January 2010 has been performed to produce a world-wide dataset of deep displacements. This numerical atlas, named ANDRO, after a traditional dance of Brittany meaning a swirl, comprises some 600 000 deep displacements. These displacements, based on Argo or GPS surface locations only, have been fully checked and corrected for possible errors found...

Anestesia do pirarucu por aspersão da benzocaína diretamente nas brânquias
Provedor de dados: 65
Autores: Honczaryk,Alexandre; Inoue,Luís Antônio Kioshi Aoki.
O pirarucu (Arapaima gigas) é um peixe que pode atingir mais de 2m e 100kg. No entanto, por ser um animal de grande porte, o risco de acidentes é bastante elevado durante o manejo. Logo, anestésicos são essenciais para segurança no trabalho. Nesse contexto, estudou-se a possibilidade do uso da benzocaína aspergida diretamente nas brânquias do pirarucu, para indução à anestesia do peixe pulmonado da Amazônia sem riscos de afogamento. Foram testadas as concentrações de 25, 50 e 75mg L-1 em indivíduos adultos (55,1±7,0kg e 1,80±0,1m) e as concentrações de 50 e 100mg L-1 em juvenis (6,0±0,6kg e 87,2±5,6cm). Os resultados mostram viabilidade do uso da benzocaína aspergida diretamente nas brânquias do pirarucu em concentrações de 50 a 100mg L-1, proporcionando...

The aim of this study was to identify the time of anesthetic induction and recovery of silver catfish (Rhamdia quelen) exposed to eugenol. It was also determined the efficacy of the anesthetic as a stress reducing agent and performed a sensory analysis of the fillets from fish exposed to this substance. The silver catfish were exposed to air for 1min to carry out biometry, and blood was collected at 0, 1 and 4 hours later. Eugenol can be used in the range of 20-50mg L-1 for anesthetic induction in silver catfish, and recovery time from anesthesia was not affected by eugenol concentration. The control group showed significantly higher cortisol levels 4 hours after biometry than at time zero. Fish anesthetized with eugenol (50mg L-1) presented significantly...

Angola’s Macroeconomy and Agricultural Growth
Provedor de dados: 31
Autores: Kyle,   Steven C.
This paper discusses the effects of Angola’s mineral wealth on the process of agricultural development. Though Angola has a rich agricultural resource base its history of civil war and extreme real exchange rate distortions has resulted in agricultural stagnation through many parts of the country. Though the security situation is now much improved, current high oil prices along with oil output increases mean that pressures on the real exchange rate will remain a fact of life for the foreseeable future.

Autores: Azanza Ricardo,J.; Borrego, R.; Same-Vargas, N.; Cruz Sosa, E.; Sergio Cabrera, E.; Pantoja, R.; García López, L.; Rodríguez García, A.
El área de anidación de Punta Francés es un tramo de alrededor de 3 km de largo, con una franja arenosa  estrecha. La playa es de baja energía, con la excepción de determinados tramos en donde la dinámica del oleaje  es mayor. Presenta una vegetación costera típica con predominio del incienso de costa (Tournefortia gnaphalodes).  La arena es de grano fino y color claro. Las zonas de mayor anidación se concentran en los tramos de arena más  gruesa y oscura, ubicados hacia los extremos de la playa, pero, los niveles de anidación, que no superan los 25  nidos en ninguna de las temporadas analizadas, son bajos comparados con otras áreas del archipiélago cubano.  La presencia de arrecifes paralelos a la costa pudiera disminuir la accesibilidad de las playas...

Animal Disease and the Industrialization of Agriculture
Provedor de dados: 31
Autores: Hennessy,   David A.; Wang,   Tong.
The industrialization of animal agriculture has fundamentally transformed animal health markets while animal health innovations have promoted this industrialization. The subtlety of these interactions shows how little we know about agricultural industrialization. To illustrate, we consider three stylized features of industrialized animal agriculture. These are the closing off of production activities from external effects, emphasis on control, and use of biosecurity measures. We find that animal disease externalities should lead to higher stocking on any given farm, and also to deficient entry into animal production. Eradicating the disease in a region increases both the stocking rate per farm and the number of farms. We show that antibiotics as a control...

Animal experimentation and scientific knowledge: a thought style?
Provedor de dados: 60
Autores: Tréz,Thales de Astrogildo e.
Animal experimentation, besides a research method extensively applied in the production of scientific knowledge, is also considered essential to science and with undeniable historical relevance in advances in human health. In this survey, a questionnaire was applied to a group of researchers involved with research based on non-animal models (n =18), and to another group involved with research based on animal models (n =18). The data analysis was grounded in Ludwik Fleck (1896 -1961) epistemological assumptions. The results suggested that there are at least two thought styles operating in consonance on the same research problem (advances in human health conditions) with significantly different conceptions not only concerning the research practices involved,...

Animal Health Economics. What Can It Do? What Are the Big Questions?
Provedor de dados: 31
Autores: Tisdell,   Clement A.
It is argued that while considerable development of animal health economics has occurred in recent decades, it has not yet achieved its potential coverage. It has been mostly applied to livestock, particularly livestock used for commerce, and its application to a range of other animals has been relatively neglected. Extending its coverage also requires widening the type of objectives taken into account in the analysis. Furthermore, the main focus of animal health economics has been on the economics of controlling and managing the occurrence of diseases. The economic role of genetics, the environment, nutrition and the comfort of animals in their health ought to be given greater attention. In the case of zoonoses, the economic analysis should be extended to...

Animal husbandry in Africa: Climate change impacts and adaptations
Provedor de dados: 31
Autores: Seo,   S. Niggol; Mendelsohn,   Robert.
This paper uses a cross-sectional approach to analyze the impacts of climate change on animal husbandry and the way farmers adapt. The study is based on surveys of almost 5000 livestock farmers across ten countries in Africa. A traditional Ricardian regression finds that the livestock net revenues of large farms in Africa are more sensitive to temperature than those of small farms. Cross-sectional analysis also reveals that large farms (but not small farms) have fewer animals per farm in warmer places. Farmers tend to select beef cattle and chickens in cool climates and goats and sheep in hot climates. Using the Ricardian results and examining climate scenarios for 2060 and beyond, the net revenues of small farms are predicted to increase as much as 120%...

Animal manure for biogas production - what happens to the soil?
Provedor de dados: 21
Autores: Løes, Anne-Kristin; Johansen , Anders; Pommeresche, Reidun; Riley, Hugh.
Utilizing animal slurry to produce biogas may reduce fossil fuel usage and emissions of greenhouse gases. However, there is limited information on how the recycling of digested slurry as a fertilizer impacts soil fertility in the long run. This is of concern because organic matter in the slurry is converted to methane, which escapes the on-farm carbon cycle. In 2010, a study of this question was initiated on the organic research farm in Tingvoll, Norway. So far, a biogas plant has been built, producing anaerobically digested slurry to be compared with undigested slurry in perennial ley and arable crops. Effects on crop yields, soil fauna, microbial communities, soil structure, organic matter and nutrient concentrations are measured.

“Animal Welfare” Practices along the Food Chain: How Does Negative and Positive Information Affect Consumers?
Provedor de dados: 31
Autores: Dentoni,   Domenico; Tonsor,   Glynn T.; Calantone,   Roger J.; Peterson,   H. Christopher.
Managing a global brand means developing its equity but also protecting it from global challenges (Shocker et al., 1994) and from the risk of negative shocks that may affect a brand (Okada and Rubstein, 1998), a multi-national company (Klein and Dawar, 2004) or a whole industry (Roehm and Tybout, 2006). Negative information shocks may arise because of sudden product-harm crises or scandals (Klein and Dawar, 2004; Roehm and Tybout, 2006), such as food-borne disease outbreaks or environmental violation practices. In these situations, providing positive brand information can mitigate the effect of negative information shocks on consumers’ brand evaluations and buying intentions (Smith and Vogt, 1995; Okada and Rubstein, 1998; Klein and Dawar, 2004; Roehm and...

Animals’ Health Control Efficiency in Northwest Portugal: A Two-stage DEA Approach
Provedor de dados: 31
Autores: Costa,   Leonardo; Oude Lansink,   Alfons G.J.M.; Silva,   Elvira.
A two-stage approach is employed to analyze the efficiency of cooperatives responsible for ruminants’ disease control (OPP) at the farm level in Northwest Portugal. In the first stage, Data Envelopment Analysis (DEA) is used to estimate and decompose input-based overall inefficiency for each OPP. The input-based inefficiency measures are generated using the directional input distance function. In the second stage, the inefficiency estimates are regressed on environmental and organizational factors in order to explain efficiency differentials. Despite substantial environmental differences, the empirical results indicate that most cooperatives can reduce costs by improving scale efficiency and pure technical efficiency.

Annual Report Readership: A Study of an Agricultural Supply Cooperative
Provedor de dados: 31
Autores: Shanahan,   Yvonne P.; Lord,   Beverley R.; Robb,   Alan J.
Recent corporate collapses have focussed attention on the (un)reliability of financial information. However, although the agricultural sector, which is significant globally, is run primarily using the cooperative form, there is scant research on these users' perception of financial information. Therefore this paper examines members' readership and understanding of the annual reports of a large, fertiliser cooperative. The findings show that there is a lack of readership of the annual report, due to a lack of understanding and a lack of time. A minority of non-readers trust directors to "do a good job". Preparers of information should focus on making reports more user-friendly and evidence suggests that financial information could be released more...

Annual, seasonal and spatial abundance of the seabob shrimp Xiphopenaeus kroyeri (Decapoda, Penaeidae) off the Southeastern coast of Brazil
Provedor de dados: 42
Autores: HECKLER,GISELE S.; LOPES,MATEUS; SIMÕES,SABRINA M.; SHIMIZU,ROBERTO M.; COSTA,ROGERIO C. DA.
We investigated the influence of environmental factors in spatial and temporal distribution of the seabob shrimp Xiphopenaeus kroyeri in Santos Bay and São Vicente Estuary, state of São Paulo, Brazil. Monthly samples were obtained, from May 2008 through April 2010, from four locations in the estuary and four in the bay. No individual was collected in the estuary and this was attributed to the low salinity means recorded in this environment. We collected 109,153 individuals in the bay and there was no difference in abundance between the two years comprised by the study period. The similarity in spatial distribution can be related to sediment grain size that in all sampling locations showed great amount of very fine sand. The largest amount of reproductive...

Annual self-reseeding legumes and their application into Mediterranean Organic cropping systems
Provedor de dados: 21
Autores: Driouech, Noureddin.
Self-reseeding winter annual legumes are an essential component of the Mediterranean natural resources. This study aimed to investigate self-establishment potential, ability of biological nitrogen fixation (BNF), of seven annual self-reseeding legumes and their short–term pre-crop effect on succeeding zucchini and lettuce crops. Results are presented from field experiment in Apulia region, South of Italy, where the self-reseeding legumes were screened during two cropping cycles.  For the first cropping cycle (2005-2006) preliminary results suggested that Trifolium spp. performed better than Medicago spp. Among the seven species, five were more suitable to the site’s conditions.  T. angustifolium and M. polymorpha gave the best results. T. angustifolium...

Autores: Lo Bue, N.; Vangriesheim, Annick; Khripounoff, Alexis; Soltwedel, T.
Four sets of measurements performed between 2005 and 2010 in the deep central Atlantic, the deep north-western Mediterranean Sea, and in the Arctic Ocean revealed strange anomalies in the performance of the Aanderaa optode 3830 sensors mounted on RCMI I current meters in low current regimes (current speeds &gt; 10 cm s(-1)). All oxygen datasets collected during these deployments showed significant drops of oxygen (50-100 mu mol) affecting the data stability of the optode sensors in low hydrodynamic conditions. High correlations between all acquired parameters (temperature, turbidity, speed and direction of currents) verified that no unusual event occurred in the mooring areas during the periods of acquisition, although natural events responsible for such...

Anotação semântica de dados geoespaciais para a agricultura.
Provedor de dados: 14
Autores: MACARIO, C. G. do N.
Dados geoespaciais são base para sistemas de decisão em vários domínios. Para serem usados esses dados precisam ser analisados e interpretados por especialistas. Essas interpretações geralmente não são armazenadas ou correspondem apenas a alguma informação textual e em linguagem própria, gravadas em arquivos técnicos. A ausência de soluções eficientes para armazená-las leva a problemas como retrabalho e dificuldades de compartilhamento de informação. Este trabalho apresenta uma solução para esse problema que baseia-se no uso de anotações semânticas, uma abordagem que promove um entendimento comum dos conceitos usados. Com a adoção de workflows científicos e também de um esquema de metadados e de ontologias bem conhecidos, foi especificado e parcialmente...

El uso de ontologías para facilitar la anotación semántica de imágenes médicas ha sido un enfoque ampliamente utilizado. Una limitación particular de este enfoque, es el reducido número de ontologías con un alto nivel de completitud, debido en parte, a la dificultad que representa su evolución. En este artículo se propone un método que facilita la evolución de ontologías a partir de las contribuciones hechas por expertos de dominio mediante el etiquetado social de imágenes médicas. El método guía el proceso colaborativo durante el descubrimiento del cambio. Adicionalmente, se presenta una herramienta construida sobre Web Protégé para dar soporte al método propuesto.

Another color morph of Sporophila Seedeater from the capuchinos group (Aves, Emberizidae)
Provedor de dados: 76
Autores: Repenning,Márcio; Rovedder,Cristiano E.; Fontana,Carla S.
The genus Sporophila (Cabanis, 1844) unites about 30 species of small seedeaters that predominantly inhabit open or semi-open areas in the Neotropical region. The taxonomy of this group is based on morphological studies from collected male specimens. The dynamic spatial and temporal variation in the male plumage and lack of knowledge of their vocalizations make it difficult to properly diagnose some species even today, so these two aspects account for the existing taxonomic dilemmas involving Sporophila. During a four-year field study, we investigated the natural history of a breeding population of Sporophila melanogaster (Pelzeln, 1870). This is an endemic species in Brazil, which reproduces in the high-altitude grasslands of the Atlantic Forest biome. We...

Autores: Santos,Pollyanna Pereira; Vasconcellos,Alexandre; Jahyny,Benoit; Delabie,Jacques Hubert Charles.
Ants are among the most common arthropods that colonize termite nests. The aim of this study was to identify the ant fauna associated to termite nests found in a cacao plantation in the county of Ilhéus, Bahia, Brazil, with emphasis on the fauna that uses the nests as foraging and/or nesting environment. For this purpose, 34 active, decadent and abandoned nests of Nasutitermes corniger, N. ephratae and Nasutitermes sp., with different volumes and degrees of activity, were dissected. A total of 54 ant species, belonging to 23 genera and five subfamilies, was found in the constructions. The active, decadent and abandoned termite nests presented, respectively, six, eight and 48 ant species. Crematogaster acuta and Ectatomma tuberculatum were the most frequent...

Autores: Aravind B. Chavhan; Santosh S. Pawar; Mumtaz M. Baig.
Ants deserve a special place in the study of ecology, including behavior, given their species richness, social habits, and high densities, contributing to much of the animal biomes on earth (Gadagkar et.at. 1993). As ants can be studied virtually everywhere from forest interiors below ground, right up to the kitchen, we attempted a study to assess the ant species richness in a variety of habitats in and around Amravati city. The prime objective of this study is to prepare a partial checklist of ants of Amravati and to compare species richness between selected study sites. Eight study sites with different levels and types of vegetation were selected for the study.&amp;#xd;&amp;#xa;We employed an &amp;#x201c;all out search&amp;#x201d; method for collection...

Antarctic icebergs distributions, 2002-2010
Provedor de dados: 5
Autores: Tournadre, Jean; Ardhuin, Fanny; Legresy, Benoit.
Interest for icebergs and their possible impact on southern ocean circulation and biology has increased during the recent years. While large tabular icebergs are routinely tracked and monitored using scatterometer data, the distribution of smaller icebergs (less than some km) is still largely unknown as they are difficult to detect operationally using conventional satellite data. In a recent study, Tournadre et al. (2008) showed that small icebergs can be detected, at least in open water, using high resolution (20 Hz) altimeter waveforms. In the present paper, we present an improvement of their method that allows, assuming a constant iceberg freeboard elevation and constant ice backscatter coefficient, to estimate the top-down iceberg surface area and...

(Anti-) Coordination in Networks
Provedor de dados: 31
Autores: Kovarik,   Jaromir; Mengel,   Friederike; Romero,   Jose Gabriel.
We study (anti-) coordination problems in networks in a laboratory experiment. Partici- pants interact with their neighbours in a fixed network to play a bilateral (anti-) coordination game. Our main treatment variable is the extent to which players are heterogeneous in the number of connections (neighbors) they have. Other network characteristics are held constant across treatments. We find the following results. Heterogeneity in the number of connections dramatically improves the rate of successful coordination. In addition, even though there is a multiplicity of Nash equilibria theoretically, a very sharp selection is observed empirically: the most connected player can impose her preferred Nash equilibrium almost always and observed Nash equilibria are...

Antibacterial activity of chitosan and the interpolyelectrolyte complexes of poly(acrylic acid)-chitosan
Provedor de dados: 52
Autores: Ortega-Ortiz,Hortensia; Gutiérrez-Rodríguez,Baltazar; Cadenas-Pliego,Gregorio; Jimenez,Luis Ibarra.
The antimicrobial activity of chitosan and water soluble interpolyelectrolyte complexes of poly(acrylic acid)-chitosan was studied. Chitosans of two different molecular weights were tested at different concentration for 0.5 to 5 g·L-1 as antimicrobial agents against P. aeruginosa and P. oleovorans. In both cases, the best microbial inhibition was obtained with the concentration of 5 g·L-1. However, the interpolyelectrolyte complexes of poly(acrylic acid)-chitosan with composition φ =2 produced higher antibacterial activity than the two chitosans at the concentration of 0.5 g·L-1. The NPEC2 complex was more effective than chitosans. This could be attributed to the number of moles of the amino groups of chitosan and the carboxylic acid groups of the...

Biofilm formation results in medical threats or economic losses and is therefore a major concern in a variety of domains. In two-species biofilms of marine bacteria grown under dynamic conditions, Pseudoalteromonas sp. strain 3J6 formed mixed biofilms with Bacillus sp. strain 4J6 but was largely predominant over Paracoccus sp. strain 4M6 and Vibrio sp. strain D01. The supernatant of Pseudoalteromonas sp. 3J6 liquid culture (SN3J6) was devoid of antibacterial activity against free-living Paracoccus sp. 4M6 and Vibrio sp. D01 cells, but it impaired their ability to grow as single-species biofilms and led to higher percentages of nonviable cells in 48-h biofilms. Antibiofilm molecules of SN3J6 were able to coat the glass surfaces used to grow biofilms and...

Autores: Machado,Alexandre Paulo; Vivi,Viviane Karolina; Tavares,José Roberto; Gueiros Filho,Frederico José; Fischman,Olga.
In this work, different reactions in vitro between an environmental bacterial isolate and fungal species were related. The Gram-positive bacteria had terminal and subterminal endospores, presented metabolic characteristics of mesophilic and acidophilic growth, halotolerance, positive to nitrate reduction and enzyme production, as caseinase and catalase. The analysis of partial sequences containing 400 to 700 bases of the 16S ribosomal RNA gene showed identity with the genus Bacillus. However, its identity as B. subtilis was confirmed after analyses of the rpoB, gyrA, and 16S rRNA near-full-length sequences. Strong inhibitory activity of environmental microorganisms, such as Penicillium sp, Aspergillus flavus, A. niger, and phytopathogens, such as...

Antibodies targeting Cancer stem cells, A novel pattern in Immunotherapy
Provedor de dados: 17
Autores: Sarfaraz Alam.
Antibody targeting of cancer is showing clinical and commercial success after deep research and development over the last 3 decades. They have the great potential to deliver long-term cures but a shift in thinking towards a cancer stem cell (CSC) model for tumour development is certain to have an impact on how antibodies are selected and developed, the targets they bind to and the drugs used in combination with them. CSCs have been identified from many human tumours and share many of the characteristics of normal stem cells such as the ability to renew and metabolically or physically protect themselves from xenobiotic and DNA damage. Targeting CSCs could be a strategy to improve the outcome of cancer therapy. Monoclonal antibodies are clinically and...

Autores: Spilki,Fernando Rosado; Almeida,Renata Servan de; Arns,Clarice Weis.
Bovine respiratory syncytial virus (BRSV) causes pneumonia in young cattle. Modified-live-virus (MLV) and inactivated vaccines are currently used for the control of clinical effects of BRSV infections in cattle. On the present research, the stimulation of specific anti-BRSV immunoglobulin isotypes was investigated, through the use of different commercially available adjuvants (Water-in-oil emulsion, Quil A, Aluminum-hydroxide) in inbred mice (Balb/C and C57BL/6). BRSV antibodies were measured using an enzyme-linked immunosorbent assay (ELISA) and the results were compared to the antibody levels induced by immunization of animals using live-BRSV-virus. Water-in-oil emulsion and alum- adjuvant preparations induced higher levels of IgG1 immunoglobulins,...

Antibody-antigen interactions: What is the required time to equilibrium?
Provedor de dados: 17
Autores: Karl Andersson; Hanna Bj&amp;#xf6;rkelund; Magnus Malmqvist.
The use of antibodies is widespread in many areas including in-vivo and in-vitro diagnostics, quantitative analysis in research laboratories and as therapeutic substances. Since the methods for generation of antibodies has improved and regularly results in high-affinity interactions, the standard assays used for quantification of the interaction properties should be revisited because they do not necessarily produce accurate results. Here we show that in several cases, the affinity determination of strongly binding antibodies will be inherently difficult when using standard procedures, due to impractically long incubation times. Real-time kinetic analysis is often the only realistic alternative for affinity determination.

This paper is a methodological contribution to emerging debates on the role of learning, particularly forward-looking (anticipatory) learning, as a key element for adaptation and resilience in the context of climate change. First, we describe two major challenges: understanding adaptation as a process and recognizing the inadequacy of existing learning tools, with a specific focus on high poverty contexts and complex livelihood-vulnerability risks. Then, the article examines learning processes from a dynamic systems perspective, comparing theoretical aspects and conceptual advances in resilience thinking and action research/learning (AR/AL). Particular attention is paid to learning loops (cycles), critical reflection, spaces for learning, and power....

Since November 2007 until May 2009, 1,778 serum samples of cattle from dairy herds of the Southwest of Paraná State, Brazil, were used for search of anti-Neospora caninum antibodies. The frequency of seropositive animals, assessed by IFAT, was 24.2% (431/1,178), showing a relatively high occurrence in the studied population. These results show that Neospora caninum is widely distributed in the dairy cattle in the Southwest of Paraná State. The presence of Neospora caninum in a herd is worrisome, since this protozoan is closely related with reproductive disorders and low milk production in cattle.

Bowdichia virgilioides H.B.K stem bark (Fabaceae), locally known as "sucupira-preta", is a reputed folk-remedy to treat some inflammatory disorders. To validate its traditional claim, the ethanolic extract from B. virgilioides was evaluated in several animal models of inflammation and nociception. The extract at oral doses of 100 to 1000 mg/kg body weight caused a significant inhibition of carrageenan-induced hind paw oedema, suppression of exudate volume and leukocyte immigration in rat pleurisy induced by carrageenan, and reduction of granuloma weights in the model of subcutaneous granulomas promoted by cotton pellets. In addition, the plant extract significantly inhibited the vascular permeability increase induced by intraperitoneal acetic acid. It also...

Autores: Ramos,Henrique Pereira; Braun,Glaucia Hollander; Pupo,Mônica Tallarico; Said,Suraia.
Papulaspora immersa and Arthrinium state of Apiospora montagnei Sacc. were isolated from the roots of Smallanthus sonchifolius (yacón). The crude extracts from their cultures inhibited the growth of Staphylococcus aureus, Kocuria rhizophila, Pseudomonas aeruginosa and Escherichia coli. The more relevant results were observed in the ethyl acetate extract from P immersa against P aeruginosa (90 µg/mL) and ethyl acetate extract from Arthrinium state of A montagnei Sacc. against P aeruginosa (160 µg/mL). The two endophytic fungi isolated from yacón roots as well as their antimicrobial activity detected in the crude extracts cultures were being reported for the first time.

Autores: Nascimento,Maristela da Silva do; Moreno,Izildinha; Kuaye,Arnaldo Yoshiteru.
This study investigated the antimicrobial activity of Enterococcus faecium FAIR-E 198 against Bacillus cereus, Listeria monocytogenes and Staphylococcus aureus. Using the critical-dilution method, the bacteriocin produced by E. faecium FAIR-E 198 inhibited all L. monocytogenes strains evaluated (1,600 to 19,200 AU mL-1). However, none of the B. cereus and S. aureus strains investigated were inhibited. The maximum activity of this bacteriocin (800 AU mL-1) was observed in MRS broth, while the activity in milk was 100 AU mL-1. In the co-cultivation test in milk, B. cereus K1-B041 was reduced to below the detection limit (1.00 log CFU mL-1) after 48 h. E. faecium reduced the initial L. monocytogenes Scott A population by 1 log CFU mL-1 after 3 h at 35ºC....

The minimum inhibitory concentration (MIC) was determined for 13 antibiotics against Clostridium perfringens isolated from Brazilian piglets. The collection of isolates was performed in June to October 2010. All isolates were susceptible to amoxicillin and ceftiofur, whereas most were resistant to tetracycline and lincomycin. Avilamycin and narasin were more effective against isolates from non-diarrheic than from diarrheic piglets. The other antimicrobials were less active in need of high concentrations to inhibit the growth of the C. perfringens type A. These results suggest the need for further studies evaluating molecular factors related to the antimicrobial resistance of C. perfringens.

The emergence of multidrug-resistant strains of Mycobacterium tuberculosis underscores the need of continuous developments on new and efficient methods to determine the susceptibility of isolates of M. tuberculosis in the search for novel antimicrobial agents. Natural products constitute an important source of new drugs, but design and implementation of antimycobacterial susceptibility testing methods are necessary for evaluate the different extracts and compounds. A number of biological assay methodologies are in current use, ranging from the classical disk diffusion and broth dilution assay format, to radiorespirometric (BACTEC), dye-based, and fluorescent/luminescence reporter assays. This review presents an analysis on the in vitro susceptibility...

Anting behavior by the White-bearded Manakin (Manacus manacus, Pipridae): an example of functional interaction in a frugivorous lekking bird
Provedor de dados: 49
Autores: Cestari,César.
Behavioral studies of birds have reported several functions for active anting. Maintenance of plumage and prevention from ectoparasites are some examples. In this context, anting by males may be of particular importance in a classical lek mating system, where male-male competition is common and individuals with higher fitness may be more successful at attracting of females. In the present note, I describe the anting behavior of White-bearded Manakin (Manacus manacus) and I relate it to lek breeding and feeding (frugivory) habits of the species. Males used up to seven Solenopsis sp. ants. They rubbed each small ant from 4 to 31 times on undertail feathers until the ants were degraded; ants were not eaten. Males then searched for a new ant in the court....

Snakebites comprise a serious health problem in several countries due to their global incidence, which exceeds 2.5 million per year, and the elevated number of victim fatalities. To counteract envenomations, antivenoms have been used regularly for more than a century. Apart from side effects including anaphylactic reactions, antivenoms are not able to efficiently neutralize local tissue damage, which contributes to increasing the severity and morbidity observed in patients. This fact, in turn, may be responsible for economic hardship, particularly in rural populations of developing countries. In the present work, we evaluated the antiophidian properties of 12 Brazilian plant extracts against the hemolytic, coagulant, hemorrhagic and proteolytic effects of...

It is possible to incorporate a lot of natural antioxidants into the human organism by consuming berries which can prevent diseases generated by the action of free radicals. Antioxidants neutralize free radicals and thus protect the organism from the oxidative damage of lipids, proteins, and nucleic acids. Berries stand out as one of the richest sources of antioxidant phytonutrients among various fruits and vegetables. The objective of this research was to determine antioxidant capacity (AC), total anthocyanins (TA), and total phenols (TP) of wild and cultivated berries in different localities of La Araucanía and Los Ríos Regions in Chile. These parameters were analyzed by using the free radical 2,2-diphenyl-1-picrylhydrazyl hydrate (DPPH) method,...

We evaluated the genotype and maturity effects on antioxidant activity and phenolic compounds of whole, skin and pulp fruits from three highbush blueberry cultivare (cv. Brigitta, cv. Bluegold and cv. Legacy) grown in southern Chile. Total antioxidant activity (TAA) in ripe fruits varied among the cultivare in the order Legacy &gt; Brigitta &gt; Bluegold. We found that TAA in unripe green and fully ripe fruits was high and similar between them, whereas the lowest levels were found in intermediate ripe fruits. The same trend was observed for fruit total phenolic content. This could be attributed to the higher concentrations of phenolic acids (mainly chlorogenic acid) and flavonols (mainly rutin) at immature fruit stages; whereas the high TAA in mature...

Human neutrophils stimulated by phorbol myristate acetate (PMA), an activator of protein kinase C, produce active oxygen by NADPH oxidase in intracellular structures. We added succinimidyl ester of dichlorodihydrofluorescein diacetate (H2DCFDA), which first emits fluorescence when oxidized with active oxygen species, to neutrophils to produce active oxygen, in order to investigate the antioxidant effects of protocatechuic acid, ferulic acid, and caffeic acid which belong to polyphenols and are widely distributed among plants. Particularly, we focused on examining whether these substances capture and eliminate active oxygen inside or outside the neutrophil cytoplasm and whether these substances inhibit NADPH oxidase. Fluorescence microscopy demonstrated...

Background/Question/Methods:&amp;#xd;&amp;#xa;Evergreen plants, growing in seasonally cold environments, must cope with a severe imbalance between light absorption and its utilization, as low temperatures during winter inhibit photosynthetic carbon reduction. In such conditions photoprotective mechanisms are critical, including the leaf antioxidant systems of plants. In a previous study examining _Taxus cuspidata_, we found significant increases in the enzyme glutathione reductase (GR) and the metabolite glutathione (GSH) during winter, but no increases in the enzymes superoxide dismutase, ascorbate peroxidase (APX) or the metabolite ascorbate (ASC). These results led to the hypothesis that GR and GSH serve an important role during winter stress that was...

Antioxidant supplementation to the exercising horse
Provedor de dados: 96
Autores: Williams,Carey A.
Evidence of oxidative stress in horses has been described in reports dealing with intense and endurance exercise. Oxidative stress occurs when antioxidant systems are insufficient causing oxidation to potentially damage DNA, proteins, and lipids, and contribute to degenerative changes. Vitamin E is the most commonly supplemented antioxidant in horses and has been shown that horses in exercise conditioning may require higher intakes of vitamin E than recommended. Also in various species vitamin C potentiates the effects of vitamin E; however, under maintenance conditions horses have the ability to synthesize sufficient ascorbate, the demand increases as stress on the body is increased. Competitive endurance horses were estimated to consume 1.2 to 5-times...

Provedor de dados: 61
Autores: Freitas,Cleverson D. T. de; Souza,Diego P. de; Araújo,Eliane S.; Cavalheiro,Mariana G.; Oliveira,Luciana S.; Ramos,Márcio V.
In this study, proteins extracted from laticifer cells of three plants were examined by electrophoresis, mass spectrometry (MALDI-TOF) and characterized in respect of proteolytic, chitinolytic and anti-oxidative activities by means of zymography and colorimetric assays. Acidic proteins with molecular masses between 12.5 and 74.5 kDa predominated in laticifers of P. rubra. This profile was not found in laticifers of C. grandiflora and E. tirucalli. The later was poor in respect of proteins. Strong anti-oxidative activity of superoxide dismutase (E.C. 1.15.1.1) was detected in P. rubra and C. grandiflora latices, and to a lesser extent ascorbate peroxidase (E.C. 1.11.1.1) and isoforms of peroxidase were seen. Catalase (E.C. 1.11.1.6) was detected only in...

Anti-parasitic action and elimination of intracellular Toxoplasma gondii in the presence of novel thiosemicarbazone and its 4-thiazolidinone derivatives
Provedor de dados: 56
Autores: Carvalho,C.S.; de Melo,E.J.T.
Toxoplasma, which infects all eukaryotic cells, is considered to be a good system for the study of drug action and of the behavior of infected host cells. In the present study, we asked if thiosemicarbazone derivatives can be effective against tachyzoites and which morphological and ultrastructural features of host cells and parasites are associated with the destruction of Toxoplasma. The compounds were tested in infected Vero cell culture using concentration screens (0.1 to 20 mM). The final concentration of 1 mM was chosen for biological assay. The following results were obtained: 1) These new derivatives decreased T. gondii infection with an in vitro parasite IC50% of 0.2-0.7 mM, without a significant effect on host cells and the more efficient...

Antiplatelet activity of white and pink Nelumbo nucifera Gaertn flowers
Provedor de dados: 60
Autores: Durairaj,Brindha; Dorai,Arthi.
Nelumbo nucifera Gaertn (Nelumbonaceae) a plant used in Ayurvedic medicine (common name: lotus), is a perennial, large and rhizomatous aquatic herb most prevalent in South India. Preliminary phytochemical screening of both white and pink Nelumbo nucifera flowers revealed the presence of phytochemical constituents (flavonoids, alkaloids, phenols etc,). Hence, an attempt has been made to screen the effect of Nelumbo nucifera flowers (both types) on platelet aggregation. The antiplatelet activity of hydroethanolic extract of both types of flowers was studied using platelet-rich plasma in different concentrations (100-500µg/ml). Both white and pink Nelumbo nucifera flower extracts showed dose-dependent effective antiplatelet activity with maximum activity at...

Antipolítica, representación y participación ciudadana (Tema central)
Provedor de dados: 122
Autores: Montúfar, César.
El cuestionamiento a la democracia representativa liberal, se encuentra enraizado en tradiciones antipolíticas y en una crisis de representación. Sin embargo, las propuestas de democracia participativa, parecen ser una variante de recursos corporativos y medios de presión particularistas. La democracia representativa no excluye la participación, sino que supone diversos mecanismos de colaboración con la autoridad legítimamente constituida, petición independiente de cuentas, expansión de derechos e innovación política. No se ignora que un fuerte obstáculo se halla constituido por partidos políticos que tienden a expresar conducciones personalizadas e impulsan intereses privados.

Antiprotozoal steroidal saponins from the marine sponge Pandaros acanthifolium
Provedor de dados: 20
Autores: Regalado, E.L.; Tasdemir, D.; Kaiser, M.; Cachet, N.; Amade, P.; Thomas, O.P.
The chemical composition of the Caribbean sponge Pandaros acanthifolium was reinvestigated and led to the isolation of 12 new steroidal glycosides, namely, pandarosides E-J (1-6) and their methyl esters (7-12). Their structures were determined on the basis of extensive spectroscopic analyses, including two-dimensional NMR and HRESIMS data. Like the previously isolated pandarosides A-D (13-16), the new compounds 1-12 share an unusual oxidized D-ring and a cis C/D ring junction. The absolute configurations of the aglycones were assigned by interpretation of CD spectra, whereas the absolute configurations of the monosaccharide units were determined by chiral GC analyses of the acid methanolysates. The majority of the metabolites showed in Vitro activity...

The objective of this study was to determine the effect of eight 5-hydroxy-5-trifluoromethyl-4,5-dihydro-1H-1-carboxyamidepyrazoles (TFDPs) on rat body temperature and baker’s yeast-induced fever. TFDPs or vehicle (5% Tween 80 in 0.9% NaCl, 5 mL/kg) were injected subcutaneously and rectal temperature was measured as a function of time in 28-day-old male Wistar rats (N = 5-12 per group). Antipyretic activity was determined in feverish animals injected with baker’s yeast (Saccharomyces cerevisiae suspension, 0.135 mg/kg, 10 mL/kg, ip). 3-Ethyl- and 3-propyl-TFDP (140 and 200 μmol/kg, respectively, 4 h after yeast injection) attenuated baker’s yeast-induced fever by 61 and 82%, respectively. These two effective antipyretics were selected for subsequent...

Provedor de dados: 16
Autores: Nieukerken, E. van; Wagner, D.; Baldessari, M.; Mazzon, L.; Angeli, G.; Girolami, V.; Duso, C.; Doorenweerd, C.
A grapevine leafminer Antispila oinophylla van Nieukerken &amp; Wagner, sp. n., is described both from eastern North America (type locality: Georgia) and as a new important invader in North Italian vineyards (Trentino and Veneto Region) since 2006. The species is closely related to, and previously confused with A. ampelopsifoliella Chambers, 1874, a species feeding on Virginia creeper Parthenocissus quinquefolia (L.) Planchon., and both are placed in an informal A. ampelopsifoliella group. Wing pattern, genitalia, and DNA barcode data all confirm the conspecificity of native North American populations and Italian populations. COI barcodes differ by only 0–1.23%, indicating that the Italian populations are recently established from eastern North America....

This study evaluated the antiulcer activity of an ethanolic extract of Encholirium spectabile (ES-EtOH) by using different standard experimental models of induced acute gastric ulceration. ES-EtOH (100 mg/kg p.o) protected the gastric mucosa against ulceration that was induced by absolute ethanol (53%), ethanol/HCl (75 %), ibuprofen (52 %) and ischemia/reperfusion (43 %). It also restored catalase activity and non-protein sulfhydryl group concentration in the gastric wall of mice that had been treated with ethanol. The pre-treatment of mice with N-nitro-L-arginine (70 mg/kg i.p.) abolished the protective activity of ES-EtOH, which indicates that prostaglandins, antioxidant compounds and nitric oxide synthase activity are involved in the gastroprotective...

Antiviral activity of (E)-cinnamaldehyde revisited with nanoscience tools
Provedor de dados: 17
Autores: Arunava Goswami; Ayesha Rahman.
Contradictory results have been reported regarding the anti-viral activity of (E)-cinnamaldehyde, a major constituent (~69%) of cinnamon. Here we show that (E)-cinnamaldehyde alone has very low antiviral property contrary to the belief of commoners. There are early sporadic reports in ancient medicinal practices that fine sand was used for increasing the efficacy of antiviral drugs. Can we increase the efficacy of (E)-cinnamaldehyde marginally by using one of the major constituents of sand like silica? Yes, when nanosilica is used as a carrier during (E)-cinnamaldehyde administration, the antiviral efficacy of the resultant cocktail increases marginally. Therefore, (E)-cinnamaldehyde consumed for centuries in tribal therapy as well as in alternative...

This work aimed to study the annual variation of temperature of the coat surface and other traits of coat in Holstein cows managed in a tropical environment by separately considering black coat and white coat. It was measured the coat thickness (mm) characteristic, hair length (mm), hair number (hair/cm²) and coat surface temperature on 191 crossbred cows with 7/8 and 31/32 Holstein composition distributed in 3 herds in a semi-arid environment. Less dense coats with shorter, flattened hair occurred predominantly in March, a time coinciding to high levels of solar radiation. This type of coat shows low resistance to the flux of latent and sensitive heat through the skin, thus favoring heat loss. The black coat surface temperature was on average 4ºC higher...

This study presents the species richness, temporal distribution and reproductive activity of anurans from the Uaimií State Forest (Floresta Estadual do Uaimií – FLOE Uaimií), situated in the Quadrilátero Ferrífero region, municipality of Ouro Preto, Minas Gerais state, Brazil. Field activities were performed monthly from September 2009 to August 2010. We recorded 36 anurans species, distributed in 10 families. The greatest richness of the sampled sites corresponds to a permanent rivulet in a secondary forest. The majority of anuran species presented seasonal vocalization activity pattern, mainly in the rainy season. The anuran species composition of FLOE Uaimií is similar to others studied areas from the Quadrilátero Ferrífero region.

The Upper Paraguay River Basin is located in the center of South America and harbors one of the largest wetland in the world, known as Pantanal. This floodplain is surrounded by uplands, which presently have most of their area converted into pastures or monocultures, besides being poorly known scientifically. Also, most of these upland areas are considered conservation priorities. Here we present a list of anuran species from a savanna-like area (municipality of Camapuã, state of Mato Grosso do Sul, Brazil) inserted in the uplands surrounding the Pantanal floodplain, in the Upper Taquari River sub-basin, and evaluate the effectiveness of the sampling effort. Data were obtained through active searches in 22 plots in aquatic habitats, during the rainy season...

Anurofauna da Floresta Estacional Semidecidual da Estação Ecológica dos Caetetus, Sudeste do Brasil
Provedor de dados: 49
Autores: Brassaloti,Ricardo Augusto; Rossa-Feres,Denise de Cerqueira; Bertoluci,Jaime.
A Floresta Estacional Semidecidual é considerada uma das formações florestais mais ameaçadas e suprimidas pela expansão agrícola do início do século passado, com sua cobertura vegetal reduzida a menos de 8% da original. Estudos sobre taxocenoses de anfíbios anuros nessa formação florestal ainda são escassos, mesmo quando consideramos as poucas áreas de floresta primária que restaram. Apresentamos neste estudo os resultados de um levantamento de espécies de anfíbios anuros da Estação Ecológica dos Caetetus, uma unidade de conservação que abriga importante remanescente de Floresta Estacional Semidecidual na região Centro-oeste do estado de São Paulo, região considerada prioritária para conservação no estado. Foram registradas 34 espécies distribuídas em nove...

Ziel des Verbundvorhabens war die Erarbeitung einer kombinierten Regulierungsstrategie für die  Kohlmottenschildlaus Aleyrodes proletella in Ökologischem Kohlgemüse, mit den zwei Ansatzpunkten Kulturschutznetz &amp; natürlichen Gegenspielern. Das sofortige Abdecken von Rosenkohl mit feinmaschigem Kulturschutznetz (0,8 x 0,8mm) ab dem Verpflanzen bis Ende Oktober erzielte durchgängig 77% Befallssenkung in der Hauptbefallsphase im September. Aufdecken der Netze für mechanische Unkrautbekämpfung bildet ein kritisches Zeitfenster für Initialbefall. Verzicht auf Hacken durch Anwendung einer biologisch abbaubaren Mulchfolie brachte allerdings keinen zusätzlichen Regulationserfolg.

Anwendung natürlich vorkommender Gegenspieler der Kohlmottenschildlaus (KMSL) in Kohlgemüse im kombinierten Einsatz mit Kulturschutznetzen
Provedor de dados: 21
Die Kohlmottenschildlaus Aleyrodes proletella [Hom., Aleyrodidae] hat sich zunehmend zu einem Qualitätsschädling im ökologischen Kohlanbau entwickelt. Insbesondere der Anbau von Rosen- und Grünkohl in Nordhessen und Niedersachsen ist betroffen. Wie die Praxiserfahrung und zuvorige Versuche zeigten, reicht die Abdeckung der Pflanzen mit Kulturschutznetzen als alleinige Regulierungsmaßnahme nicht aus.  Im Projekt soll eine praxistaugliche Regulierungsstrategie für die Kohlmottenschildlaus (Aleyrodes proletella, [Hom., Aleyrodidae]), (KMSL) in ökologischem Rosenkohl erarbeitet werden. Hierbei kommt der Einsatz von Kulturschutznetzen (0,8x0,8mm) in Kombination mit zwei aussichtsreichen natürlichen Gegenspielern (Encarsia tricolor, Clitostethus arcuatus) unter...

Anwendung zweier Methoden zur Überprüfung der N-Versorgung von Kartoffeln im Ökologischen Landbau
Provedor de dados: 21
Autores: Dresow, Jana F.; Böhm, Herwart.
Der vorliegende Beitrag befasst sich mit der Überprüfung der N-Versorgung von Kartoffeln im Ökologischen Landbau mittels zweier Methoden. Zum einen wurde die für den konventionellen Landbau entwickelte Stängelsaftanalyse mittels Nitracheck-Reflektometer angewandt; zum anderen die Blattanalyse mit der Gesamtstickstoffbestimmung mittels CNS-Analysator. Die Messungen zeigen im Verlauf der Vegetationsperiode eine Abnahme sowohl der Nitratgehalte im Stängelsaft als auch der Stickstoffgehalte im Blatt. Diese Abnahme war bei den NO3-Gehalten im Stängelsaft deutlich stärker ausgeprägt als bei den Nt-Gehalten in den Blättern. Es bestehen lineare, aber sortenspezifische Zusammenhänge zwischen den NO3-Gehalten im Stängelsaft und den Nt-Gehalten in den...

Autores: Pascon,J.P.E.; Ondani,A.C.; Junior,D.P.; Andrade,J.N.M.; Camacho,A.A.
A 10-month-old intact female mixed breed dog was referred for evaluation of exercise-induced dyspnea and a low grade II/VI systolic murmur was detected. The communication between ascending aortic and pulmonary trunk was observed by detecting a continuous flow just above the semilunar valves on echoDopplercardiography and attested by surgery. After the surgical procedure, the dog was presented in good clinical conditions without exercise-induced dyspnea, reflecting the importance of an early and accurate diagnostic for the therapeutic success. This is the first Brazilian report of this rare congenital disease and the unique well succeed surgery in the veterinary literature.

Autores: William M. Urbanski; Brian  G. Condie.
As more research literature in the biological sciences is made available in electronic format, text mining systems are increasingly being used to improve the ability of investigators to retrieve relevant information. Through the use of advanced indexing techniques that utilize biological ontologies, semantic databases, and other formal representations of biological concepts text mining systems have been able to effectively parse biological literature. While text mining systems are increasingly effective at creating the linkages required to provide context-specific search results, the systems themselves are difficult to set up and use by novice computer users due to the highly technical nature of the applications. Because most researchers in the biological...

This aim of this article is to analyze the relation of size and operational efficiency of sugar and ethanol plants in the northeastern region of São Paulo state. In order to achieve this goal, a survey was conducted to identify the consumption of the main resources (inputs) and product creation (outputs) in a random sample of twenty six units, which allowed for their classification according to size. This enabled the creation of an efficiency ranking, using Data Envelopment Analysis (DEA), whose variables were chosen by the stepwise method. The results suggest that, for the plants studied, there is no direct relation between size and operational efficiency, which can be explained by technical aspects associated to the inputs. The results provide subsides...

Autores: Silva,Janaína de Oliveira Costa; Lacerda,Guilherme Araújo; Castro,Evaristo Mauro de; Chalfun-Júnior,Antonio; Paiva,Luciano Vilela; Oliveira,Cynthia de.
A micropropagação de indivíduos do gênero Musa vem sendo aplicada em larga escala para obtenção de mudas de qualidade fitossanitária. O cultivo in vitro pode levar a ocorrência de variação somaclonal que pode acarretar em prejuízos aos produtores. Atualmente, a diferenciação das plantas variantes somaclonais é possível somente quando as mesmas encontram-se em condições de campo, mediante crescimento exagerado, conhecido como gigantismo. Mutantes para a produção de giberelina apresentaram fenótipo anão e esta mutação já foi revertida com a aplicação de ácido giberélico exógeno. A anatomia de plântulas cultivadas in vitro e ex vitro fornece informações que podem auxiliar na melhoria das técnicas de micropropagação e na sua seleção precoce. Objetivou-se...

Autores: Martins, Cristiani Campos; UFV; Soares, Antonio Alves; UFV; Ramos, Márcio Mota; UFV; Reis, Edvaldo Fialho dos; UFES.
Para avaliar o efeito da cloração orgânica na uniformidade de distribuição de água e na vazão de um tubogotejador com vazão de 2,2 L h-1, foram testados quatro níveis de concentrações de dicloroisocianurato de sódio (N1 = 0, N2 = 15, N3 = 30 e N4 = 45 mg L-1 de cloro livre). As avaliações foram realizadas no início do experimento e a cada 100 horas de funcionamento do sistema, totalizando 8 avaliações. No cálculo da uniformidade de aplicação de água foram utilizados os coeficientes de uniformidade de Christiansen (CUC), de distribuição (CUD) e de emissão (Us). Também se realizou o estudo da vazão e do coeficiente de variação da vazão (CVq). Verificou-se que no nível N1 ocorreram reduções de 23; 30,2 e 8,35%, para o CUC, CUD e Us, respectivamente, sendo que...

Autores: MELO, G. W. B. de; SETE, P. B.; BRUNETTO, G.; AMBROSINI, V. G.; ALBARELLO, J. B.; COMIM, J. J.
A necessidade de adubação nitrogenada de manutenção do pessegueiro (Prunus persica) no Rio Grande do Sul (RS) e em Santa Catarina (SC) é estabelecida com base no teor total de N nas folhas completas, no crescimento dos ramos do ano e na produtividade esperada (BRUNETTO et al., 2007). Quando definida a necessidade, além da ureia, em função da disponibilidade, podem ser utilizadas outras fontes, como o composto orgânico, que, na adubação de manutenção, é aplicado na superfície do solo sem incorporação. O composto orgânico aplicado em solos de pomares pode promover o incremento do teor de carbono orgânico do solo, o que, por consequência, pode favorecer a agregação, melhorando a estrutura, a porosidade, a capacidade de armazenamento de água e aumentando a...

Oscilações de temperatura acompanhadas de altos índices pluviais e flutuação de umidade relativa do ar, nas fases de maturação e pré-colheita, podem provocar perdas na qualidade física, fisiológica e na sanidade de sementes. A aplicação de dessecantes em pré-colheita contribui para a redução da exposição das sementes a condições climáticas desfavoráveis e para diminuir a possibilidade de prejuízos à germinação e vigor. Nesta pesquisa o objetivo foi avaliar o efeito da época de aplicação de dessecantes e da antecipação da colheita sobre a qualidade fisiológica de sementes de soja.

Aplicação foliar de manganês em soja transgênica tolerante ao glyphosate
Provedor de dados: 65
Autores: Basso,Claudir José; Santi,Antônio Luis; Lamego,Fabiane Pinto; Girotto,Eduardo.
O amarelecimento da soja Roundup Ready após aplicação do glyphosate pode estar associado à deficiência momentânea de manganês. Por isso, com a hipótese de que soja tolerante ao glyphosate necessitaria de uma adição suplementar de manganês, o objetivo deste trabalho foi avaliar diferentes manejos na aplicação foliar de manganês sobre alguns parâmetros da soja. Foram desenvolvidos dois experimentos, um no município de Taquaruçú do Sul e outro em Boa Vista das Missões, RS, no ano agrícola 2009/2010. Foram testados os seguintes tratamentos: 1) sem aplicação de glyphosate, com controle manual das plantas daninhas e sem aplicação foliar de manganês (testemunha); 2) sem aplicação de glyphosate, com controle manual das plantas daninhas e uma aplicação foliar de...

A aplicação foliar, objetivando o acúmulo do nutriente na semente, é uma tecnologia recente e, por isso, pouco se sabe sobre o seu efeito na qualidade fisiológica e a influência da sua aplicação sobre a produtividade das plantas. Neste Trabalho objetivou-se avaliar a produtividade das plantas que receberam a aplicação de Mo via foliar em diferentes doses, e a qualidade fisiológica das sementes provenientes dessas plantas. A fonte de molibdênio usada foi o molibdato de sódio (39% Mo). As sementes receberam o Mo por meio de aplicações foliares durante o processo de maturação, em aplicação única e parcelada em duas vezes, feitas entre os estágios R5.2 e R5.4, em dois ensaios, em Lavras e Ituiutaba, MG. Os tratamentos para os dois ensaios foram: aplicação de...

APLICAÇÃO SUPERFICIAL DE CALCÁRIO COM DIFERENTES TEORES DE MAGNÉSIO E GRANULOMETRIAS EM SISTEMA PLANTIO DIRETO
Provedor de dados: 90
Autores: Rodrighero,Maik Barbosa; Barth,Gabriel; Caires,Eduardo Fávero.
RESUMO A correção da acidez do solo no sistema plantio direto (SPD) é feita por meio da aplicação de calcário na superfície sem incorporação. Com a hipótese de que a fonte e granulometria dos corretivos interferem na velocidade de reação no solo em curto prazo e na resposta das culturas à calagem na superfície em SPD, foram realizados dois experimentos, sendo um em Latossolo Vermelho Distrófico textura muito argilosa e outro em Neossolo Litólico Húmico textura franco-arenosa, no período de 2010 a 2012. O delineamento empregado, em cada experimento, foi em blocos completos ao acaso, no esquema fatorial 2 × 2 × 4, com três repetições. Os tratamentos foram constituídos de duas fontes de calcário, calcítico (25-50 g kg-1 MgO) e dolomítico (160-180 g kg-1 MgO),...

Autores: Zapata-Sierra,Antonio; Manzano-Agugliaro,Francisco.
Para el estudio de los hidrogramas generados mediante simulador de lluvia y cuando el suelo presenta una capacidad de infiltración alta el método original de Singh no funciona bien. Para ello se propone un método basado en la superposición de soluciones parciales, generadas a partir de la teoría de la onda cinemática para obtener un hidrograma combinado. En este estudio se fabricó un simulador de lluvia donde se realizaron 16 ensayos de escorrentía sobre un suelo permeable. Al comparar los resultados obtenidos entre el método original y el propuesto, se mostró que se puede aplicar con buenos resultados la metodología de la onda cinemática para generar la respuesta a la lluvia en este tipo de sistemas. Además se mostró la influencia de la intensidad de la...

Aplicación del análisis de rango reescalado R/S para la predicción de genes en el genoma vegetal
Provedor de dados: 109
Autores: Almanza Pinzón,Martha Isabel; López López,Karina; Téllez Villa,Carlos Eduardo.
La predicción de genes es en la actualidad uno de los principales desafíos de la genómica. La predicción permite realizar experimentos con alta probabilidad de encontrar genes de interés y comparar regiones de ADN de importancia agronómica entre genomas; además, ayuda a restringir los espacios de búsqueda en las bases de datos. Un procedimiento estadístico con base en el análisis R/S y el coeficiente de Hurst fue desarrollado para caracterizar y predecir genes y los componentes estructurales de estos (exones e intrones) en los genomas eucariotas completos de Arabidopsis thaliana, Oriza sativa y Mus musculus. Algoritmos en lenguaje de programación Python fueron desarrollados para extraer, filtrar y modelar más del 80% de las secuencias de genes registradas...

Autores: López Cruz, Marco Antonio.
El Elastic Net Bayesiano (BEN) es un método de regresión que utiliza una mezcla de las penalizaciones L1 y L2 (Kyung et al., 2010, Li y Lin, 2010). Se ha demostrado que este modelo puede ser usado exitosamente cuando el tamaño de muestra es mucho menor que el número de predictores (n &lt;&lt; p). En este trabajo se muestra cómo utilizar este modelo para incluir de forma conjunta Marcadores Moleculares (MM) y Pedigree, ampliamente utilizados en gen etica cuantitativa en la llamada selección asistida por MM. Por medio de validación cruzada, el poder predictivo del BEN se compara con el de otros modelos: LASSO Bayesiano y Regresión Ridge Bayesiana, usando datos reales de rendimiento de cultivares de trigo y cebada, y tiempos de floración de maíz.

Aplicación del método de zonación morfo-estructural para identificar nudos sismogènicos en la región costera y cadenas montañosas de los andes septentrionales del Ecuador
Provedor de dados: 20
Autores: Chunga, Kervin; Michetti, Alessando M.; Gorshkov, Alexander I.; Panza, Giuliano F.; Soloviev, Alexander; Martillo, Carlos.
Due to the lack of information in the catalogue of historic earthquakes (1951-2010) and also of potential but unmapped faults in the field, the seismic zoning modeling for Ecuador does not define parameters of equivalent attenuations of the tectonic activity of the territory. The aim of this research is to provide new engineering techniques for seismic hazard evaluation. The technique of this study is based on the assumption that strong earthquakes are associated within structural nodes that are specific structures formed around intersections of fault zones. The nodes have been delineated with a morphostructural zoning method, based on the idea that the lithosphere is made-up of different-scaled blocks, separated by mobile boundaries. These blocks are...

A series of studies have shown that the heavy burdens of diarrheal diseases in the first 2 formative years of life in children living in urban shanty towns have negative effects on physical and cognitive development lasting into later childhood. We have shown that APOE4 is relatively common in shanty town children living in Brazil (13.4%) and suggest that APOE4 has a protective role in cognitive development as well as weight-for-height in children with heavy burdens of diarrhea in early childhood (64/123; 52%), despite being a marker for cognitive decline with Alzheimer’s and cardiovascular diseases later in life. APOE2 frequency was higher among children with heaviest diarrhea burdens during the first 2 years of life, as detected by PCR using the...

Autores: Meça,K.K.O.L.; Martins,A.S.; Del Puerto,H.L; Vasconcelos,A.C.
Apoptose e seus mecanismos reguladores são eventos fisiológicos cruciais para a manutenção da homeostase placentária, e o desequilíbrio desses processos pode comprometer a função placentária e, consequentemente, o sucesso da gravidez. Neste estudo, investigou-se a apoptose utilizando-se histomorfometria em lâminas coradas em HE e submetidas à reação de TUNEL. Além disso, avaliou-se a expressão de Bcl-2 e das caspases 8 e 3, pela reação de polimerase em cadeia em tempo real, em placentas saudáveis em diferentes estádios de gestação. Amostras de placentônios de vacas com quatro, seis e nove meses de gestação foram colhidas e processadas. O índice apoptótico aumentou progressivamente com o avanço da gestação. Tanto o Bcl-2 quanto as caspases 3 e 8 foram...

Auxin and insulin promote Zea mays embryo growth, induce S6 ribosomal protein (S6rp) phosphorylation, and promote specific protein synthesis. The objective of this research was to test a possible cross-talk between insulin and auxin transduction pathways in Z. mays coleoptiles, typical auxin target tissues. Auxin and insulin produced differential quantitative and qualitative stimulation of cytoplasmic and ribosomal protein phosphorylation, and specific patterns of de novo synthesized cytoplasmic proteins. In addition, insulin induced S6rp phosphorylation was strongly inhibited by rapamycin, indicating target of rapamycin (TOR) kinase participation; auxin-induced S6rp phosphorylation was insensitive to this inhibitor. Phosphatidic acid (PA), a second...

Apparent non-canonical trans-splicing is generated by reverse transcriptase in vitro
Provedor de dados: 17
Autores: David Tollervey; Jonathan Houseley.
Trans-splicing, the in vivo joining of two RNA molecules, is well characterized in several groups of simple organisms but was long thought absent from fungi, plants and mammals. However, recent bioinformatic analyses of expressed sequence tag (EST) databases suggested widespread trans-splicing in mammals^1-2^. Splicing, including the characterised trans-splicing systems, involves conserved sequences at the splice junctions. Our analysis of a yeast non-coding RNA revealed that around 30% of the products of reverse transcription lacked an internal region of 117 nt, suggesting that the RNA was spliced. The junction sequences lacked canonical splice-sites but were flanked by direct repeats, and further analyses indicated that the apparent splicing actually...

Mezcal is an alcoholic beverage produced only in selected regions of Mexico under appellation of origin status from the Word Intellectual Property Organization. While it has been produced in Mexico for many centuries, mezcal’s appellation of origin was only granted in 1995. Therefore efforts to produce and market it as a premium product have a relatively short history. This case study examines developments in the production and marketing of this unique product, and the activities of the marketing cooperative El Tecuán in Guerrero State in this process.

Autores: Gourmelon, Michele; Caprais, Marie-paule; Le Mennec, Cecile; Mieszkin, Sophie; Ponthoreau, C.; Gendronneau, M.
Faecal contamination sources were identified in coastal areas around the Guerande-Atlantique peninsula using two microbial source tracking (MST) methods: (i) Bacteroidales host-specific 16S rRNA gene markers measured by real-time PCR and (ii) F-specific bacteriophage (FRNAPH) genotyping. Both methods were used on 63 water samples from 7 water courses. HF183 marker and bacteriophage genogroup II (FRNAPH II) were detected in all water samples and in the majority of water samples, respectively, from La Torre stream (W5), Piriac (W2), R2000 (W3) and Mazy (W7) rain water drains, and also detected, less frequently, in Le Nau drain (W4), suggesting contamination by human faecal sources at these sites.

The effect of applications of low concentrations of salicylic acid (SA) on the number of flowers and the date of flower initiation in Petunia (Petunia híbrida) in reported in this paper. Concentrations of 1 μM to lpM of SA were spread on three occasions to the shoot of plantlets cultivated in greenhouse conditions. Analysis of the results showed that all the concentrations of SA tested increased the number of open flowers per plant. Concentrations as low as lpM or 0.lnM induced positive riesponses by 33 % and 37 %, as compared with that of the control. The highest concentration of 1 μM increased not only the number of flowers by 72 % but also induced early flowering by six days.

Application of microbial α-amylase in industry - A review
Provedor de dados: 58
Autores: Souza,Paula Monteiro de; Magalhães,Pérola de Oliveira e.
Amylases are one of the main enzymes used in industry. Such enzymes hydrolyze the starch molecules into polymers composed of glucose units. Amylases have potential application in a wide number of industrial processes such as food, fermentation and pharmaceutical industries. α-Amylases can be obtained from plants, animals and microorganisms. However, enzymes from fungal and bacterial sources have dominated applications in industrial sectors. The production of α-amylase is essential for conversion of starches into oligosaccharides. Starch is an important constituent of the human diet and is a major storage product of many economically important crops such as wheat, rice, maize, tapioca, and potato. Starch-converting enzymes are used in the production of...

Application of Modified Internal Rate of Return Method for Watershed Evaluation
Provedor de dados: 31
Autores: Satyasai,   K.J.S.
The use of modified IRR in developmental projects has been demonstrated by using data pertaining to four watersheds — two from Tamil Nadu and two from Maharashtra. The conventional internal rate of return (IRR) widely used in project evaluation, suffers from certain problems, most important one being the assumption of reinvestment at the rate of IRR, which has been often contested in project evaluation literature. The ranking of projects based on IRR and NPV may also come into conflict due to this assumption. Scale and time span differences across projects often make it difficult to compare. In India, the use of conventional IRR still prevails even though improvements have been suggested in literature long ago, perhaps for the reasons of ease in handling....

Polycyclic aromatic hydrocarbons (PAHs) constitute a group of priority pollutants which are present at high concentrations in the soils of many industrial contaminated sites. Pollution by these compounds may stimulate growth of organisms able to live in these environments causing changes in the structure of the microbial community due to some cooperative process of metabolization of toxic compounds. A long-term PAH-contaminated soil was stored for several years and used to analyze the native microbiota regarding their ability to grow on pyrene, benzo[a]pyrene, as well as in mixtures of LMW- and HMW-PAHs. Molecular profiles of the microbial community was assessed by PCR-DGGE of 16S rRNA gene, and the number of bands observed in DGGE analyses was interpreted...

We have developed a parallel, rapid, high-throughput oligonucleotide microarray-based assay for the reliable detection and genotyping of three cry genes (cry1, cry2 and cry9) in Bacillus thuringiensis (Bt). After the non-polymerase chain reaction (PCR), amplified Bt genomic DNA were fluorescent-labeled using a random primer.   The corresponding oligonucleotide probes were designed for the different cry genes that can hybridize Bt genomic DNA after cluster analysis and were printed on glass slides. This microarray has unambiguously detected and identified the cry genes in 10 isolates and reference Bt. Our data demonstrates that the microarray assay is simple and rapid for the detection and genotyping of genes. This type of assay is also a potentially...

Application of representational difference analysis to identify genomic differences between Bradyrhizobium elkanii and B. Japonicum species
Provedor de dados: 58
Autores: Soares,René Arderius; Passaglia,Luciane Maria Pereira.
Bradyrhizobium elkanii is successfully used in the formulation of commercial inoculants and, together with B. japonicum, it fully supplies the plant nitrogen demands. Despite the similarity between B. japonicum and B. elkanii species, several works demonstrated genetic and physiological differences between them. In this work Representational Difference Analysis (RDA) was used for genomic comparison between B. elkanii SEMIA 587, a crop inoculant strain, and B. japonicum USDA 110, a reference strain. Two hundred sequences were obtained. From these, 46 sequences belonged exclusively to the genome of B. elkanii strain, and 154 showed similarity to sequences from B. japonicum genome. From the 46 sequences with no similarity to sequences from B. japonicum, 39...

APPLICATION OF SOLID-STATE FERMENTATION FOR CELLULASE ENZYME PRODUCTION USING TRICHODERMA VIRIDE
Provedor de dados: 31
Autores: Mojsov,   Kiro.
The Solid-state fermentation (SSF) is alternative to submerged fermentation for production antibiotics, single cell protein, enzymes, organic acids, biofuel, etc. However, the advantages of SSF in various processes are found to be greater than in submerged fermentation. This technique not only decreases the cost of the process but also makes product cheaper for consumers. The paper describes experimental application of  SSF on wheat straw  for production of mycelia protein and cellulase enzymes by Trichoderma viride. This actual waste from agriculture industry was used as a nourishing base by Trichoderma viride in SSF for cellulase enzyme production. Growth and enzymes production by Trichoderma viride  were evaluated on wheat straw and alkali treatment...

Applications of protective cultures, bacteriocins and bacteriophages in fresh seafood and seafood products
Provedor de dados: 5
Autores: Pilet, Marie-france; Leroi, Francoise.
Microbial seafood-borne disease represents 10 to 20% of the total food-borne outbreaks. Most of them are from bacterial origin and involve seafood products that have been contaminated by pathogenic Vibrio, Listeria monocytogenes and histaminogen bacteria. On the other hand, seafood products are very sensitive to the development of spoiling bacteria producing off-odours. Pathogenic and spoiling microflora are not always reduced or limited by the processing steps that are currently used in these foodstuffs, and the interest for alternative techniques such as bioprotection to improve quality and safety of seafood has increased in the last years. Among the microbial flora of lightly preserved seafood products, lactic acid bacteria usually become dominant...

Apply of Textmining Method to Study the Roles in Improving the Health by Lactoferrin, a Multi-Functional Milk Protein
Provedor de dados: 17
Autores: Kei-ichi K. Shimazaki; Tatsuya T. Kushida; Koji K. Yamauchi; Toshihisa T. Takagi.
Lactoferrin is a metal-binding glycoprotein found in milk, blood and other exocrine secretions.  This is a multi-functional protein that exhibits many activities such as: anti-microbial, anti-viral, immunomodulatory, anti-inflammatory, anti-tumor, anti-metastatic, cell growth-promoting, and anti-oxidant activities, as well as regulation of granulopoiesis and iron absorption, etc.  To date, a number of academic reports concerning the biological activities of lactoferrin have been published and are easily accessible through public databases.  In order to overcome the information overload associated with lactoferrin information, we have applied the text mining method to the accumulated lactoferrin literature.  To this end, we used the information extraction...

APPLYING FUZZY THEORY CONCEPTS TO THE ANALYSIS OF EMPLOYMENT DIVERSIFICATION OF FARM HOUSEHOLDS: METHODOLOGICAL CONSIDERATIONS
Provedor de dados: 31
Autores: Fritzsch,   Jana.
The Deliverable 7.2 (D7.2) of the SCARLED project provides methodological considerations for applying fuzzy set theory to the analysis of employment diversification of farm households. It presents a Mamdani's type fuzzy inference model and describes its application within the project's framework. The model consists of ten variables that are grouped into the four factors: (i) necessity to diversify, (ii) internal preconditions, (iii) external preconditions, and (iv) attitudes. The coherence of these four factors with the integrated framework for the analysis of nonfarm rural employment is discussed. The model will be realised in the Fuzzy Logic Toolbox from MATLAB®. Forty four membership functions and 138 rules are going to be implemented, tested, and...

We present a simple subtraction procedure of GDDSC as a modification of the original DSC and GDRDA methods. Genetically Directed Differential Subtraction Chain (GDDSC) is a process by which highly related genomes are compared in order to isolate tags carrying the polymorphisms. &amp;#xd;&amp;#xa;To detect specific DNA fragment (tag), we can then monitor offspring plants for efficient molecular breeding. The GDDSC protocol was applied to isolation of new sex related clones from cucumber plants (_Cucumis_ _sativus_ L.) and new tissue culture response clones from rye (_Secale_ _cereale_ L.). The newly identified tags, obtained by GDDSC represent pools of candidate genes and other sequences, which could serve as potential markers for requested traits.

Applying Optimization and the Analytic Hierarchy Process to Enhance Agricultural Preservation Strategies in the State of Delaware
Provedor de dados: 31
Autores: Messer,   Kent D.; Allen,   William L., III.
Using agricultural preservation priorities derived from an analytical hierarchy process by 23 conservation experts from 18 agencies in the state of Delaware, this research uses weighted benefit measures to evaluate the historical success of Delaware’s agricultural protection fund, which spent nearly $100 million in its first decade. This research demonstrates how these operation research techniques can be used in concert to address relevant conservation questions. Results suggest that the state’s sealed-bid-offer auction, which determines the yearly conservation selections, is superior to benefit-targeting approaches frequently employed by conservation organizations, but is inferior to the optimization technique of binary linear programming that could have...

Applying regression quantiles to farm efficiency estimation
Provedor de dados: 31
Autores: Kaditi,   Eleni A.; Nitsi,   Elisavet I.
This article is concerned with the methodological question of frontier production functions estimation for agriculture, and the appropriateness of regression quantiles, as a useful semi-parametric approach. Better insights are reached using the proposed methodology that provides robust farm efficiency scores estimates. Using the 2007 Farm Accountancy Data Network (FADN) data for Greece, analysis shows that the distribution of efficiency scores is closer to normality when employing regression quantiles, while underestimation of efficiency obtained by other parametric or deterministic methods based on the conditional mean can be avoided. The results further suggest that government support aimed at enhancing farms viability should be directed towards payments...

Applying Transaction Cost Economics: A Note on Biomass Supply Chains
Provedor de dados: 31
Autores: Altman,   Ira J.; Sanders,   Dwight R.; Boessen,   Christian R.
Agricultural supply chains, especially those from producer to first handler, are relatively mature institutions. While agricultural economists often observe the evolution of marketing structures in developing nations, it is a rare opportunity to research a developing market within North America. The emerging bioenergy industry—which relies on non-food crops such as straw—provides the potential to research and potentially impact the development of new supply chains. Here, we briefly review the literature related to biomass supply chains, pose a transaction cost approach to studying their development, and then discuss the procurement strategies of an industry leader: the Iogen Corporation.

Autores: De Decker, Sophie.
Oyster production is the main aquaculture activity in France and is dominated by the rearing of Crassostrea gigas. In the aquatic ecosystems where the species is grown, bacteria of the genus Vibrio are found to be dominant. Two Vibrio species, V. splendidus and V. aestuarianus, are frequently associated with Crassostrea gigas summer mortality episodes. The aims of this work were to study Vibrio-oyster interactions and their modulations according to virulence mechanisms and to genetic and physiological parameters of the host. Using specific, sensitive and quantifying diagnostic tools developed in this study, as well as standardized experimental infection trials, some components of the virulence of Vibrio strains and host susceptibility were delineated and...

A vizsgálatokból megállapítható, hogy a precíziós gazdálkodás bevezetésére irányuló beruházások megtérülése és az üzemi méretek között szoros az összefüggés. A feltételezett öt- és hatéves megtérülés mellett a hozam- vagy az elvárt kamatszint-változást a nagyobb területű üzemek képesek ellensúlyozni.    --Return on investment in projects for implementing precision farming is closely related to farm size. In the event of the envisaged repayment over five or six years, farms with a larger area can balance changes in yield or interest rate.

O cultivo de mandioca no Maranhão ocorre em terras bastantes frágeis, a maioria delas arenosas ou médias, com baixa capacidade para fornecer nutrientes exigidos em maiores quantidades pela mandioca ( fósforo, cálcio, magnésio e potássio). Além disso, a prática da derrubada e queima da vegetação nativa, e não utilização de adubos na mandioca contribuem para enfraquecer ainda mais a terra, fazendo com que, geralmente, seja feito apenas um cultivo de mandioca em cada área, e depois ela é deixada em pousio (descansando).

Durante el último siglo se ha identificado una tendencia secular positiva en el crecimiento físico de la mayor parte de las poblaciones del mundo, sobre todo en niños y adolescentes. La situación en Chile no ha sido distinta reflejándose un aumento en todos los grupos etáreos constituyendo uno de los más serios problemas de salud pública en Chile. Frente a este problema, es que se observa la tendencia del estado nutricional y composición corporal de dos muestras de estudiantes de enseñanza media de las comunas de Valparaíso, Viña del Mar y Concón, V Región, Chile, en los períodos 1984-1985 y 2009-2010. Las cohortes presentan diferencias significativas con un aumento en las variables IMC (Índice de Masa Corporal) y porcentaje de grasa corporal (p&lt; 0,05)...

Aproximación empírica a la solución bivariada de avenidas de diseño en embalses sin hidrometría
Provedor de dados: 115
Autores: Campos-Aranda,Daniel F.
La estimación de avenidas de diseño, conjuntando información hidrométrica de gastos máximos anuales y sus correspondientes volúmenes de su hidrograma (V), ha sido resuelta en México a través del análisis probabilístico bivariado. Las soluciones de este procedimiento aplicado a 15 presas existentes y una en proyecto, se analizaron para buscar un patrón de comportamiento estadístico y formular una aproximación empírica, la cual no requiere de la información citada. De acuerdo con este enfoque el hidrograma de la avenida de diseño tiene un gasto pico (Qp) con un periodo de retorno de 275 años, estimado con base en métodos regionales, su tiempo al pico (Tp) es igual al tiempo de concentración de la cuenca y su forma y volumen (V) están definidos por un...

Interrogation of the human proteome in a highly multiplexed and efficient manner remains a coveted and challenging goal in biology.  We present a new aptamer-based proteomic technology for biomarker discovery capable of simultaneously measuring thousands of proteins from small sample volumes (15 [mu]L of serum or plasma).  Our current assay allows us to measure ~800 proteins with very low limits of detection (1 pM average), 7 logs of overall dynamic range, and 5% average coefficient of variation.  This technology is enabled by a new generation of aptamers that contain chemically modified nucleotides, which greatly expand the physicochemical diversity of the large randomized nucleic acid libraries from which the aptamers are selected.  Proteins in complex...

Lo que podría llamarse la cultura constitucional boliviana está enmarcada por una apreciación colectiva de la ley que mantiene los estatutos legales en un plano mayoritariamente teórico, donde éstos no influyen gran cosa sobre el terreno de la praxis. Por lo demás vale el famoso principio práctico-pragmático: "Para el amigo todo, para el enemigo la ley".

Autores: López Maya, Margarita.
La polarización política es un fenómeno que se encuentra motivado por factores sociales, culturales y regionales. En los países andinos, especialmente en aquellos de mayor población indígena, la polarización política evidencia la herencia de una jerarquización étnica. Esta polarización emergió inicialmente en Venezuela y ha sido apropiada por crecientes actores sociales y políticos en otros países en un contexto de baja institucionalización y crisis de la representación política.
