Provedor de dados: 102
Autores: Paula Júnior,Trazilbo J.; Vieira,Rogério F.; Jesus Junior,Waldir C.; Hau,Bernhard; Teixeira,Hudson.
A study was conducted to evaluate the effects on the development of root rot on common bean, cv. 'Dufrix' after treatment with four volumes of water (0, 30%, 60%, and 90%, v/w) added to rice grains previously immersed in water for 24 hours before autoclaving and colonization of grains by Rhizoctoniasolani AG-4. Colonized rice grains and non-infested rice grains were mixed in pots with sterilized soil and sand (2:1), where beans were sown. Based on results of area under plant emergence curve, plant height, plant dry weight, and disease severity, we conclude that inoculum is more effective in causing disease when no water is added to the rice grains before autoclaving.

Noninvasive method for electrocardiogram recording in conscious rats: feasibility for heart rate variability analysis
Provedor de dados: 42
Autores: Pereira-Junior,Pedro P.; Marocolo,Moacir; Rodrigues,Fabricio P.; Medei,Emiliano; Nascimento,José H.M.
Heart rate variability (HRV) analysis consists in a well-established tool for the assessment of cardiac autonomic control, both in humans and in animal models. Conventional methods for HRV analysis in rats rely on conscious state electrocardiogram (ECG) recording based on prior invasive surgical procedures for electrodes/transmitters implants. The aim of the present study was to test a noninvasive and inexpensive method for ECG recording in conscious rats, assessing its feasibility for HRV analysis. A custom-made elastic cotton jacket was developed to fit the rat's mean thoracic circumference, with two pieces of platinum electrodes attached on its inner surface, allowing ECG to be recorded noninvasively in conscious, restrained rats (n=6). Time- and...

Serum bactericidal activity as indicator of innate immunity in pacu Piaractus mesopotamicus (Holmberg, 1887)
Provedor de dados: 45
Autores: Biller-Takahashi,J.D.; Takahashi,L.S.; Pilarski,F.; Sebastião,F.A.; Urbinati,E.C.
The immune system of teleost fish has mechanisms responsible for the defense against bacteria through protective proteins in several tissues. The protein action can be evaluated by serum bactericidal activity and this is an important tool to analyze the immune system. Pacu, Piaractus mesopotamicus, is one of the most important fish in national aquaculture. However there is a lack of studies on its immune responses. In order to standardize and assess the accuracy of the serum bactericidal activity assay, fish were briefly challenged with Aeromonas hydrophila and sampled one week after the challenge. The bacterial infection increased the concentration of protective proteins, resulting in a decrease of colony-forming unit values expressed as well as an...

Provedor de dados: 52
Autores: Wang,Yong; Huang,Wenhua; Peng,Daizhi; Hu,Yuanbin.
In this work, several major procedures of the electrophoretic mobility shift assay (EMSA) were modified including swift extraction of the nucleic protein, labeling of the probe and radioautography. The modified assay required shorter time, simplified the nucleic protein extraction, increased the radioactivity of the labeling probe, skipped the tedious process of gel drying, and produced clear images. Its results were comparable, reproducible and stable. It thus has merited for wide application.

Techniques of radioautography for medical and biological research
Provedor de dados: 56
Autores: Nagata,T.
Standard techniques for radioautography used in biological and medical research can be classified into three categories, i.e., macroscopic radioautography, light microscopic radioautography and electron microscopic radioautography. The routine techniques used in these three procedures are described. With regard to macroscopic radioautography, whole body radioautography is a standard technique which employs freezing and cryosectioning and can demonstrate organ distributions of both soluble and insoluble compounds. In contrast, in light and electron microscopic radioautography, soluble and insoluble techniques are separated. In order to demonstrate insoluble labeled compounds, conventional chemical fixations such as formalin for light microscopy or buffered...

Provedor de dados: 65
Autores: Stéfani,Marta Verardino De; Pereira,Marcelo Maia; Reche,Marcio Roberto; Mansano,Cleber Fernando Menegasso.
Adequate methods for the determination of protein digestibility in bullfrogs are important for the understanding of nutrient utilization. Therefore, this study evaluated two methods of feces collection: intestinal dissection and fecal decantation, using cylindric-conical tanks. Frogs were fed with a commercial diet (45% crude protein) which was ground and supplemented with 0.5% chromium oxide III. The frogs were fasted 48h before force-feeding (5% of the animal's live weight). For the decantation method, the animals were sacrificed 36 h after force-feeding and feces were collected directly from the large intestine. For the sedimentation method, feces were collected when they appeared in the tubes attached to the front end of the cylindric tanks. No...

Competing claims on natural resources become increasingly acute, with the poor being most vulnerable to adverse outcomes of such competition. A major challenge for science and policy is to progress from facilitating univocal use to guiding stakeholders in dealing with potentially conflicting uses of natural resources. The development of novel, more equitable, management options that reduce rural poverty is key to achieving sustainable use of natural resources and the resolution of conflicts over them. Here, we describe an interdisciplinary and interactive approach for: (i) the understanding of competing claims and stakeholder objectives; (ii) the identification of alternative resource use options, and (iii) the scientific support to negotiation processes...

Complex systems are shaped by cross-scale interactions, nonlinear feedbacks, and uncertainty, among other factors. Transdisciplinary approaches that combine participatory and conventional methods and democratize knowledge to enable diverse inputs, including those from local, informal experts, are essential tools in understanding such systems. The metaphor of a &amp;#8220;bridge&amp;#8221; to overcome the divide between different disciplines and knowledge systems is often used to advocate for more inclusive approaches. However, there is a shortage of information and consensus on the process, methodologies, and techniques that are appropriate to achieve this. This paper compares two case studies from Peru and South Africa in which community-level assessments...

Jody; UCLA Fielding School of Public Health ; jody.heymann@ph.ucla.edu.
The need to track climate change adaptation progress is being increasingly recognized but our ability to do the tracking is constrained by the complex nature of adaptation and the absence of measurable outcomes or indicators by which to judge if and how adaptation is occurring. We developed a typology of approaches by which climate change adaptation can be tracked globally at a national level. On the one hand, outcome-based approaches directly measure adaptation progress and effectiveness with reference to avoided climate change impacts. However, given that full exposure to climate change impacts will not happen for decades, alternative approaches focus on developing indicators or proxies by which adaptation can be monitored. These include systematic...

The challenge confronting those seeking to understand the institutional dimensions of global environmental change and patterns of land-use and land-cover change is to find effective methods for analyzing the dynamics of socio-ecological systems. Such systems exhibit a number of characteristics that pose problems for the most commonly used statistical techniques and may require additional and innovative analytic tools. This article explores options available to researchers working in this field and recommends a strategy for achieving scientific progress. Statistical procedures developed in other fields of study are often helpful in addressing challenges arising in research into global change. Accordingly, we start with an assessment of some of the enhanced...

An Integrated Approach to Analyzing (Adaptive) Comanagement Using the &amp;#8220;Politicized&amp;#8221; IAD Framework

Autores: Whaley, Luke; Water Science Institute, Cranfield University; l.whaley@cranfield.ac.uk; Weatherhead, Edward K.; Water Science Institute, Cranfield University; k.weatherhead@cranfield.ac.uk.
Scholars of comanagement are faced with a difficult methodological challenge. As comanagement has evolved and diversified it has increasingly merged with the field of adaptive management and related concepts that derive from resilience thinking and complex adaptive systems theory. In addition to earlier considerations of power sharing, institution building, and trust, the adaptive turn in comanagement has brought attention to the process of social learning and a focus on concepts such as scale, self-organization, and system trajectory. At the same time, a number of scholars are calling for a more integrated approach to studying (adaptive) comanagement that is able to situate these normative concepts within a critical understanding of how context and power...

The economic evaluation of the impact of extension programs: a suggested methodology and an application to ACAR in Minas Gerais, Brazil.
Provedor de dados: 14
Autores: ALVES, E. R. de A.; SCHUH, G. E.
Agricultural development efforts quite frequently involve programs designed to extend knowledge to farm people through various kinds of extension programs. Yet, the basic methodology for evaluating such programs is not very well developed. The typical approach is to evaluate the impact of the extension service on various measures of physical productivity, or on other characteristics of technical change. This may involve the calculation of indices of partia1 and total productivity, andlor the collection of data on rates of adoption of new modern inputs or the use of new farm practices. One objective of the present paper is to suggest the application of a methodology which appears to have promise as a means of evaluating the impact of extension programs on a...

Whatever their geographical or political point of view, Sea and coastal strategies highlight an “abyssal need” for knowledge and frequently call for a reinforcement and a better valorization of research in Marine Sciences and Technologies (MST). But, when a French public research resources inventory is needed, in the perspective of constructing a consistent action plan, we lack a framework to define thematic and disciplinary perimeter to be taken into account, to identify available data, to choose practical evaluation or estimation methods. The following study is a proposal to answer these questions. The methodology is mainly based on data collected by French High Council for Evaluation of Research and Higher Education (Hcéres) and completed by an inquiry....

En septembre 1984, MM. HERAL et DESLOUS-PAOLI organisèrent à La Tremblade, une "réunion méthodologie expérimentale mollusques". Cette rencontre faisait suite à un bref état qui s'était engagé au Congrès de Montpellier sur les "Bases biologiques de l'Aquaculture", où il était apparu que la terminologie et la méthodologie concernant le métabolisme des bivalves devaient être clarifiées. Grâce à une large information auprès des spécialistes français de la physiologie des bivalves, la réunion à La Tremblade a réuni un grand nombre de participants très motivés. Pendant 2 jours des discussions très animées ont permis de bien comprendre les échanges entre les bivalves et leur environnement et d'y jeter un regard neuf, ce qui impliquait une analyse critique du...

Reduction du nitrate dans les sediments marins. Comparaison des activites mesurees in vitro et in situ
Provedor de dados: 5
Autores: Esteves, J; Bonin, P; Blanc, F; Mille, G; Bertrand, J.
In vitro nitrate reduction in hydrocarbon-polluted marine sediments has been studied by flow-through system. By analysing the rate of nitrate comsumption as a function of nitrate concentration the authors determined the Michaelis-Menten kinetics parameters. (km = 330 mu M; vax = 2.0 mu M/g super(-1)/h super(-1). The authors found a value of 60 mu M/m super(-2)/h super(-1) for the rate of in vitro nitrate consumption derived from the above kinetic parameters and from the nitrate concentration in the sediment. In parallel a value of 67.4 mu M/m super(-2)/h super(-1) was found for the rate of nitrate consumption under in situ conditions. The great similarity between both results would favor the in vitro technique as a valid and more convenient one.

The data obtained in surveys to investigate the bacteriological aspects of the biology of two contrasting frontal systems has shown that the Inherent homeostasis and the complexity of the environment, together with the Imprecision of the data, lead to biomass values that are difficult to interpret in terms of the physical factors governing the formation of fronts. Although biochemical measurements offer some promise of providing more reliable and less confusing information, the oeed to develop high precision methods that can be made very frequently is emphasised.

The problems of application of radiocarbon method for estimation of primary production in oligotrophic waters
Provedor de dados: 5
Autores: Krupatkina, D; Berland, B; Maestrini, S.
The errors in primary production estimation by the radiocarbon method may differ from one trophic region to another. Such supposition is based on unequal phytoplanktonic structural characteristics of these regions. These errors are likely to appear rather significant in oligotrophic waters predominated by nano- and ultranano-plankton (the so-called picoplankton). The organic substance of oligotrophic waters is obviously produced by picoplankton for the most part, the need for clarifying possible errors when estimating primary production by the radiocarbon method, which is the purpose of the present work is urgent. For these topics in oligotrophic waters, measurements were carried out in two ways: (1) according to the generally accepted pattern (Sorokin,...

The present study deals with technical problems encountered under lab conditions in studies of trophic relations between deposit-feeding invertebrates and microorganisms. Using 2 pure cultures of Pseudomonas and Navicula , it was shown that these microorganisms will attach to artificial (glass beads) and natural (sand grains) substrates. Best microbial attachment was observed on sand (up to 4.8 x 10 super(8) cells.g super(-1) dry wt.). The radioactive labelling of the microorganisms depends not only on the form under which the isotope ( super(14)C) is supplied to the cultures, but also on the time and the duration of the labelling. 70% of the isotope was incorporated in a stable manner by the diatoms. The bacteria incorporated, at most, 34% of the...

Mesure de la demande chimique en oxygène dans l'eau de mer.
Provedor de dados: 5
Autores: Michel, Pierre.
Introduction: Measuring the chemical oxygen demand (COD) is a way of determining the organic matter in water based on its oxidisibility by bichromate. The presence of organic matter in sea water is one of the factors that determines the productivity of the oceans: whether this organic matter will be absorbed directly or must first be transformed into nutritive substances by bacteria. This beneficial action also has its limits. On the one hand, consumption of organic matter remains limited; when it exceeds a certain rate, there is no longer any increase in productivity. On the other hand, the excess organic matter deteriorates by consuming the dissolved oxygen and thus competes with marine life. In extreme cases, this excess can cause the eutrophication of...

Theorie et pratique de l'analyse de cohortes
Provedor de dados: 5
Autores: Mesnil, Benoit.
Foreword: Sequential analysis of the demographic structures revealed by catches is currently the method most used, in particular by work groups working together within the framework of the C.I.E.M., to assess the characteristic parameters of exploited marine populations. The reasons for its success are due to a simple analytical definition, the absence of restrictive hypotheses, and especially a singular property thanks to which the results converge towards the parameters' true values. Due to its quasi-systematic use at the outset of the process leading to exploitation regulations, it is particularly important to take in the method's advantages, limits and rules of usage. This study is, in part, a review of the principal work performed on and around cohort...

Comparison of methods for stock assessment of European hake Merluccius merluccius in the Gulf of Lions (Northwestern mediterranean)
Provedor de dados: 5
Autores: Aldebert, Yvonne; Recasens, Laura.
European hake Merluccius merluccius is the main commercial demersal species in the Gulf of Lions (Northwestern Mediterranean). This fish is exploited by French and Spanish trawler fleets and by small-scale fisheries using gillnets and longlines. Data on landings and the demography of catches by type of gear are now available for the period 1988-1991. The assessment of the hake stock was carried out using methods of virtual population analysis (VPA), or cohort analysis, based respectively on mean pseudocohorts and cohorts by age. The results of these VPA were then analysed and compared from a methodological point of view. The general results have confirmed previous studies with regard to the level of exploitation of the species. The two methods gave quite...

A HACCP-based program is developed for the Spinney Creek Oyster Company (SCOC) Shellfish Purification Facility under a pilot program funded and implemented by the New England Fisheries Development Association (NEFDA). The SCOC Facility, which includes a government approved in-house coliform laboratory, is fully licensed for oysters and clams under State of Maine and NSSP regulations. SCOC's business is producing value-added, quality-assured shellfish for premium, health conscious markets. To accomplish this, SCOC uses shellfish harvested from approved waters which is an important distinction from other purification plants which process shellfish originating from restricted waters. It was necessary to create a flow chart of the various steps involved in the...

Methodological Agreement between Body-Composition Methods in Young Soccer Players Stratified by Zinc Plasma Levels
Provedor de dados: 77
Autores: de Oliveira-Junior,Astrogildo Vianna; Casimiro-Lopes,Gustavo; Donangelo,Carmem Marino; Koury,Josely Correa; Farinatti,Paulo de Tarso Veras; Massuça,Luís; Fragoso,Isabel.
It is feasible to think that the body composition assessment may be influenced by maturational and zinc status, especially in young athletes, which perform regularly high volume of physical training. In accordance, it seems important to clarify the impact of these factors in body composition assessment in athletes, since errors may lead to mistakes in training prescription and diet elaboration, and therefore affect the athletic performance. The objective was to compare (1) different methods of body composition evaluation in young soccer players stratified by zinc plasma levels; and (2) the two reference methods using skinfolds thickness in children (Slaughter's and Lohman's equations), considering the maturation level. In this cross-sectional study, fifty...

Epidemiological investigation on envenomation: from theory to practice
Provedor de dados: 80
Autores: Chippaux,JP.
A better understanding of the epidemiology of envenoming would improve care, provided that the survey is representative, reliable and accurate. Several types of surveys could help to clarify the incidence, severity, circumstances, factors and determinants of envenomations. The relevant information may be collected and analyzed from hospital records or case report forms (for retrospective studies) or established from a protocol of longitudinal observation of cases attended at health facilities during a given period (prospective study). The household survey includes interviewing all or part of the population of a locality with a standardized questionnaire to obtain information on the circumstances of the accident. Finally, standardized questionnaires can be...

The ocean meteorological program of the Weather Bureau has two separate and distinct parts. First, there is the daily service by radio. Owing to the need for brevity, the radio reports contain a limited amount of essential information. The daily weather reports from ships and islands reveal the conditions over the ocean; when assembled on a map, including continental reports, they give a picture of weather conditions existing momentarily over a large region. A collection of observations is immediately returned to the mariner by radio broadcast so that he may draw his own weather map on shipboard. By this process, the weather at the earth's surface is mapped and much can be inferred as to conditions above the surface. Formation and movement of storms are...

Distribución del mercurio total en los tejidos de un delfín nariz de botella (Tursiops gephyreus Lahille, 1908) de la provincia de Buenos Aires (Argentina)
Provedor de dados: 20
Autores: Malaspina, A.M.; Pérez, A.; Moreno, V.J.; Bastida, R.O.; Aizpun, J.E.
Samples of seventeen different tissues of one specimen of the bottlenose dolphin Tursiops gephyreus, caught accidentally in waters adjacent to Mar del Plata by local fishermen (38°00'S; 57°20'W), were analyzed for total mercury distribution. The analytical procedure employed for total mercury involved a wet acid digestion followed by flameless atomic absorption. The method was based essentially on the one proposed by Armstrong and Uthe (1971).

Effectiveness of a Cuban  marine protected area in meeting multiple management objectives
Provedor de dados: 20
Autores: Angulo-Valdés, J. A.
In this work the management effectiveness of a Cuban MPA is assessed using an  interdisciplinary approach. A series of three hypotheses are tested to determine how  effective the Punta Frances Marine Protected Area (PFMPA) has been in meeting the  multiple objectives of conserving biological diversity and ecological integrity, while  allowing for the development of economic opportunities for tourism, and satisfying the  needs of local and distant human populations.     A new typology of benefits derived from MPAs was produced to provide managers with  a practical tool that enable them to: 1) identify the benefits at the early stages of MPA  creation, 2) state MPA objectives in a clear and measurable way, 3) assess the  effectiveness of their MPA in meeting...

To apply the first method, increments may be readable individually from the nucleus to the margin edge of otolith. This is a very time consuming operation. It can cause miscalculation of increments and errors of the age estimation. The second method, called "DGI density method" is based on the decrease of the increment width in relation to the slowing down of the growth phenomena. The more used approach according to this...

Daily growth increments (DGI) density - otolith radius relationship according to the von Bertanlanffy's growth model: application to Lutjanus sebae (Cuvier, 1828) in Seychelles. Often, age determination of fishes is conducted from several parts (scales and otoliths for teleost fishes, vertebrae, spine, opercular bones, ...) displaying seasonal marks (annuli) associated with growth checks, which can be used for the estimation of individual age. Since Panella's (1971, 1974) discovery of the daily growth increments (DGI) in the teleost otoliths, age determination with DGI method has been used more and more on larval stages of both temperate and tropical species and juvenile and adult individuals of, principally, snapper and grouper species.

The ARC-test: a standardized short-term routine toxicity test with &lt;i&gt;Artemia&lt;/i&gt; nauplii: methodology and evaluation
Provedor de dados: 27
Autores: Vanhaecke, P.; Persoone, G.
Considering the need for reliable standardized routine toxicity tests for the marine environment, a short-term bioassay with &lt;i&gt;Artemia&lt;/i&gt; nauplii has been developed for routine testing. The major reason for the selection of brine shrimp as test species is the continuous availability of &lt;i&gt;Artemia&lt;/i&gt; under the form of dry cysts from which the larvae are hatched very easily. This unique advantage solves one of the major problems of aquatic ecotoxicological tests, namely stock recruitment and/or culturing; the &lt;i&gt;Artemia&lt;/i&gt; test can be performed anywhere and at any time from dry biological material available "on the shelf".An extensive study has been performed on various brine shrimp tests published in scientific...

An automated method for the assessment of mercury adsorption rates on particulate suspended matter
Provedor de dados: 27
Autores: Baeyens, W.F.J.; Decadt, G.; Dehairs, F.A.; Goeyens, L.
A continuous filtration system connected to a mercury auto-analyzer has been constructed for obtaining mercury adsorption rates on particulate suspended matter. The capabilities of this device have been demonstrated by carrying out a series of experiments under controlled physicochemical parameter conditions on samples of the Scheldt estuary. Duplicate measurements showed coefficients of variation ranging from 1 to 6 %. Depending on the physico-chemical conditions, the initial adsorption rate per unit of dissolved mercury concentration varied between 1.2 and 8.1 x 10&lt;sup&gt;-2&lt;/sup&gt; mn&lt;sup&gt;-1&lt;/sup&gt;.

What do we know about Neotropical trap-nesting bees? Synopsis about their nest biology and taxonomy
Provedor de dados: 84
Autores: Costa,Camila Cristina Ferreira da; Gonçalves,Rodrigo Barbosa.
Abstract Cavity-nesting bees are enigmatic because they are difficult to observe in the wild, hence trap-nests (man-made cavities) provide the means by which these bees may be studied. Trap-nests is an efficient methodology to study these bees and are common worldwide. These traps have been used for a variety of reasons, including inventories, to examine pollen load, to study habitat disturbance, and bee conservation. However Neotropical trap-nesting bees’ taxonomy and biology are still poorly known and here we provide a review about these subjects. We searched for trap-nest bee studies in the Neotropical Region using Google Scholar and ISI Web of Science at any time in the past to December 2017. We found 109 independent studies, most of which were from...

Autores: SCHMITZ,M.F.; ZANDONÁ,R.R.; VARGAS,A.A.M.; GARCIA,J.R.; TUNES,L.V.M.; AGOSTINETTO,D.
ABSTRACT: The commercialization of ryegrass seeds with the presence of resistant biotypes is a serious issue that increses the dispersion of resistance to new areas without this problem. Therefore, this study aimed to develop a quick test to detect susceptible and resistant seeds to the glyphosate herbicide in order to identify contaminated seed lots with glyphosate resistance. Three experiments were carried out, one in greenhouse and the other two in the seed laboratory. First, the resistance factor (RF) was determined by a dose-response curve experiment in biotypes suspected to be resistant and susceptible to glyphosate. Then, the germination test was conducted with the selected biotypes under increasing glyphosate rates (0, 3.5, 6.9, 13.9, 27.8, 55.5,...

Autores: SCHEFFER-BASSO,S.M.; FIORENTIN,F. Jr. R.; FAVARETTO,A.
ABSTRACT: The phenological stage, post-harvest processing and quantity of material can interfere in the allelopathic activity of extracts. The objective of this study is to test the allelopathic effect of aqueous extracts of the leaves of Annoni grass (Eragrostis plana), an invader of natural pastures. Twelve extracts were prepared by combining the phenological stage of the plants when harvesting the leaves (vegetative; flowering), post-harvest processing before extraction (fresh; dry at 40 oC), and the amount of plant material (5, 15, and 25 g 100 mL-1 distilled water). Two bioassays were conducted in a germination chamber, with evaluation of germination and growth of seedlings of lettuce (Lactuca sativa) and white clover (Trifolium repens). The extracts...

The Structure of Models: Understanding Theory Reduction and Testing with a Production Example
Provedor de dados: 31
Autores: Davis,   George C.
The language of economics is the language of models. Understanding the structure of this language offers many benefits. Unfortunately, the structure is ubiquitous in implementation but absent in documentation. This paper documents the structure of models in the context of the theory reduction and testing process. The structure is used to explain why there are several legitimate ways to deal with nonspherical errors in econometric models and why the recent work on stochastic preferences and technologies is a progressive step forward for the discipline. A production modeling exercise is presented to help illuminate the concepts.

Outcome Mapping: A method for tracking behavioural changes in development programs
Provedor de dados: 31
Autores: Smutylo,   Terry.
Outcome mapping is a methodology for planning, monitoring and evaluating development initiatives that aim to bring about social change. The process of outcome mapping helps a project team or program to be specific about the actors it targets, the changes it expects to see and the strategies it employs. Results are measured in terms of the changes in behaviour, actions or relationships that can be influenced by the team or program. The methodology is comprised of several tools, which can be adapted to different contexts. It enhances team and program understanding of change processes, improves the efficiency of achieving results and promotes realistic and accountable reporting.

The status of household food security targets in South Africa
Provedor de dados: 31
Autores: Jacobs,   Peter T.
This article investigates the conceptual and methodological challenges to develop a set of baseline indicators for South African food security targets. A food security target is a well-defined and measurable goal to reduce the numbers of people who lack enough food of the right quality to live healthy lives. To derive baseline indicators for household food security, the following question is asked: what is the average cost of a nutritionally adequate food basket per person? The cost of recommended nutrient intake is based on estimates of dietary energy costs. Reported food expenditure for each household based on 2005/2006 Income and Expenditure Survey data gets compared to two dietary energy cost baskets. The food expenditure shares of the poorest...

THE FORMAL LOGIC OF TESTING STRUCTURAL CHANGE IN MEAT DEMAND: A METHODOLOGICAL ANALYSIS
Provedor de dados: 31
Autores: Davis,   George C.
In the past two decades, the profession has expended valuable resources testing structural change in meat demand with mixed results. Overlooked to date is a fundamental methodological problem that transcends all of the methods of testing for structural change.  In this study, a formal logic framework is utilized in which methodological problems associated with any hypothesis test can be analyzed.  Within this framework, it is proven that there is no valid test of any single hypothesis, including structural change.  Because of this result, additional criteria from the methodology literature are then used to evaluate the literature on structural change in meat demand.

Ex-ante impact assessment of agricultural, environmental, and rural policies has become an integral part of political decision making processes in the EU. While there is a large variety of agrienvironmental modelling tools available to analyse likely social, economic, and environmental impacts of these policies, scientifically well-founded ex-ante policy assessment tools capturing the institutional dimension are still missing. In this paper, we introduce a formalised procedure for modelling – ex-ante – institutional aspects for policy implementation: the ‘Procedure for Institutional Compatibility Assessment’ (PICA). PICA has been designed as an explorative, yet formalised methodology that enables policy makers to identify at an early stage potential...

Can Qualitative and Quantitative Methods Serve Complementary Purposes for Policy Research?: Evidence from Accra
Provedor de dados: 31
Autores: Maxwell,   Daniel G.
Qualitative and quantitative methods in social science research have long been separate spheres with little overlap. However, recent innovations have highlighted the complementarity of qualitative and quantitative approaches. The Accra Food and Nutrition Security Study was designed to incorporate the participation of a variety of constituencies in the research, and to rely on a variety of approaches—both qualitative and quantitative—to data collection and analysis. This paper reviews the way in which qualitative and quantitative methods were used in the Accra study. The argument of the paper is that the complementary use of qualitative and quantitative approaches provides a greater range of insights and perspectives and permits triangulation or the...

Demand for High-value Secondary Crops in Developing Countries: The Case of Potatoes in Bangladesh and Pakistan
Provedor de dados: 31
Autores: Bouis,   Howarth E.; Scott,   Gregory.
Secondary crops are of increasing interest to policymakers and planners in developing countries because of a desire to diversify economic activities and because of their proven potential to raise farm incomes and rural employment. To assess this potential, basic information on the demand characteristics for these crops is required. But, given the large number of possible crops to be studied, policy analysts require an estimation procedure that is less data-intensive and time-intensive than standard econometric estimation procedures. In this paper, a relatively new, low-cost procedure, based on demand for food characteristics, is applied, illustrating its usefulness for analysis of demand for potatoes in Bangladesh and Pakistan. In Asia, the potato should...

This paper analyzes the repayment rates of credit groups belonging to three group-based credit programs in Bangladesh: the Association for Social Advancement (ASA), the Bangladesh Rural Advancement Committee (BRAC), and the Rangpur Dinajpur Rural Service (RDRS). Hypotheses are drawn from economic theory relating group responsibility, and the resulting monitoring by peers, to a more effective enforcement of contractual obligations as well as to improved ability of the group as a whole to repay loans. Specific tests are performed on the following hypothesized determinants: group size, size of loans, degree of loan rationing, enterprise mix within groups, demographic characteristics, social ties and status, and occurrence of idiosyncratic shocks.

GHG Trading Framework for the U.S. Biofuels Sector
Provedor de dados: 31
Autores: Kumarappan,   Subbu; Joshi,   Satish V.
Substitution of petroleum fuels with biofuels such as ethanol and biodiesel has been shown to reduce greenhouse gas (GHG) emissions. These GHG reductions can be traded in the emerging carbon markets, and methodologies for quantifying and trading are still being developed. The main challenges in developing such GHG trading framework are analyzed. An outline of such a framework is presented that depends on the life cycle assessment of GHG reductions, along with a combination of project specific and regional standard performance measures. The advantages of assigning GHG property and trading rights to biofuel producers are discussed. At carbon prices of $10 per metric ton, estimated additional revenues to biofuel producers range from $ 17 to 64 million dollars...

Benchmarking is the practice of establishing the relative performance of a business or enterprise against an appropriate standard, generally industry standards derived from a survey of farms. The Policy Commission into the Future of Farming and Food (2002) highlighted a need to spread and improve benchmarking on farms. The requirements of effective benchmarking are illustrated in a ten step framework. The ten steps illustrate the range of expertise and resources a manager requires before being able to justify allocating resources to benchmarking. A comparison of alternative farm surveys and methodologies used to collect, analyse and report industry standards illustrates the difficulties farmers can have in identifying appropriate, robust and accurate...

The incentives researchers face depend directly upon what we as a profession value. The impacts of research can be either disciplinary by adding to economic knowledge or real world by being useful to economic agents. Various measures of research impact such as publications, citations, and external funding are discussed, and the strengths and weaknesses of each measure are evaluated. Because of the difficulty of accurately measuring research impact, we must depend on internal incentives to motivate researchers to select topics with the most potential impact.

The suitability of quantitative variables for phenological studies was evaluated in a population of the brown seaweed Sargassum vulgare from "Praia das Gordas", Angra dos Reis, Ilha Grande Bay, state of Rio de Janeiro. From June 1998 to May 1999, twenty adult individuals were randomly sampled at bimonthly intervals. Fifteen variables related to the vegetative and reproductive development of perennial and non-perennial parts of the individuals were quantified. Variables related to the non-perennial parts were more useful than those related to the perennial parts, because they showed a clear variation over the year. Vegetative development declined from June to October, and increased from October to February, when maximum median values of thallus height,...

ABSTRACT Bees have a diversified natural history, thus the methods applied to study such diversity are varied. When it comes to studies of nesting biology, bees which nest in pre-existing cavities have been reasonably well studied since researchers started using trap-nests. However, bees whose nests are built underground are poorly studied due to the difficulty of finding natural nesting areas and the absence of a method that facilitates bee nest excavation. The latter is evidenced by the lack of accurate descriptions in literature of how nests are excavated. In this study we tested cylindrical rubber refills of eraser pen as a new material to be used as a tracer of underground nest galleries in a natural nesting area of two species of Epicharis Klug, 1807...

ABSTRACT The Rules for Seed Analysis reports the use of a paper envelope in germination tests, but without any description of the exact method. The objective of this study was to evaluate the viability of the envelope method and the optimal level of substrate wetting when performing germination tests of onion seeds. The study was performed in two stages. In the first stage, a batch of seeds was evaluated using two seeding methods (on paper and in a paper envelope) and five levels of substrate wetting with differing amounts of water: 1.5, 2.0, 2.5, 3.0, and 3.5 times the dry mass of the paper. A completely randomized design was used in a 2×5 factorial scheme. In the second stage of the study, the two seeding methods mentioned in the prior were tested in...
