A first evaluation on the use of Ardea albus feathers as bioindicators of mercury burden in Amazonian ecosystems Acta Amazonica
Gomes,Andreza Lourdes; Vieira,José Luiz Fernandes; Pinheiro,Maria da Conceição Nascimento; Marceliano,Maria Luiza Videira.
We evaluated in this study the total mercury concentration in feathers of Ardea albus collected in a colony located in the city of Belem-PA, Brazil in a prospective trial for its use as bioindicators of mercury burden in Amazonia ecosystems. An Atomic absorption spectrophotometry with gold amalgamation was used for the metal determination. The total mercury average concentration in body feathers was 2.2 ± 1.5 µg.g-1 and 1.3 ± 0.9 µg.g-1 in wing feathers. No correlation was observed between total mercury concentration and the length of body or wing feathers. Total mercury concentration was above 5 µg.g-1 dry weight in only one body feather sample.

A Formal Ontology of Sequences Nature Precedings
Robert Hoehndorf; Janet Kelso; Heinrich Herre.
The Sequence Ontology is an OBO Foundry ontology that provides categories of sequences and sequence features that are applied to the annotation of genomes. To facilitate interoperability with other domain ontologies and to provide a foundation for automated inference, we provide here an axiom system for the Sequence and Junction categories in first- and second-order predicate logics.

A Framework for Assessing of the Impact of Capacity Building AgEcon
Templeton, Deborah J..
Capacity building is widely recognised as an important component of most research-for-development activities. However despite the fact that around $15 billion is spent annually on capacity building activities, there has been limited assessment of the economic returns to that investment. In recent years, the Impact Assessment Program of the Australian Centre for International Agricultural Research has turned its attention to quantifying the benefits from capacity-building. This paper sets out a framework for assessing of the impact of capacity building and presents four case studies. It does not purport to be a definitive paper by any means. Rather, it is an account of just one organisations experience. It is hoped that as work on this important area...

A Framework for BioCuration Workflows (part II) Nature Precedings
Martin Krallinger.
This is the second part of the talk ‘A Framework for BioCuration Workflows’, given by Martin Krallinger from the Spanish National Cancer Research Centre at the 'Text Mining for the BioCuration Workflow' workshop. The first part was held by Gully APC Burns (USC Information Sciences Institute, USA). This presentation covered some of the main general tasks often shared by existing literature biocuration workflows: Identification of relevant articles, identification and normalization of the actual bio-entities, the extraction of the annotation event and the identification of some evidential support (e.g. experimental evidence). Some of the important aspects, bottlenecks and potential text mining approaches were briefly...

A framework for the design and analysis of incentive systems for food safety control in supply chains AgEcon
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 general-purpose method for two-group randomization tests AgEcon
Kaiser, Johannes; Lacy, Michael G..
We outline a novel approach to calculate exact p-levels for two-sample randomization tests. The approach closely resembles permute in its applications, with the main difference being that the results are approximated only if the execution time needed to calculate exact p-levels would exceed a specified maximum. We demonstrate its use by deriving p-levels for the significance of Somers’ D, the coefficient of variation, the difference in means and in medians, and the difference in two multinomials.

A genetic linkage map of olea europaea L. using a pseudo-test cross- mapping strategy based on SSR, AFLP, ISSR, RAPD and SCAR markers Inra
Charafi, J.; Zine El Aabidine, A.; Grout, C.; Rahioui, B.; El Meziane, A.; Moukhli, A.; Boulouha, B.; El Modafar, C.; Khadari, B..
A genetic map of olive tree (Olea europaea; 2n = 46) was constructed with a total of 343 markers: 35 SSRs, 272 AFLPs, 35 ISSRs, and RAPD and SCAR scored in 140 F1 progenies from the cross between ‘Picholine marocaine’ ‘PM’ (female parent) and ‘Picholine du Languedoc’‘PL’ (male parent), respectively susceptible and resistant to Spilocaea oleagina. The female map consisted of 100 markers clustered in 24 linkage groups (LG) and covered over 1260.9 cM, while the male map was defined by 90 markers assigned to 22 linkage groups and covered 1183 cM. The consensus map obtained based on 193 markers (26 SSRs, 151 AFLPs, 12 ISSRs, 3 RAPDs, 1 SCAR) and 31 linkage groups covered 2332.8 cM.

A geometrical approach for fuzzy DEA frontiers. Repositório Alice
BIONDI NETO, L.; MELLO, J. C. C. B. S. de; MEZA, L. A.; GOMES, E. G..
Interval DEA frontiers are here used in situation where one input or output is subject to uncertainty in its measurement and is presented as an interval data. We built an efficient frontier without any assumption about the probability distribution function of the imprecise variable. We take into account only the minimum and the maximum values of each imprecise variable. Two frontiers are constructed: the optimistic and the pessimistic ones. We use fuzszy relationships to introduce a new efficiency index based on a set of some Fuzzy T Norms. We will explore only the case where only on single variable presents a certain degree of uncertainty.

A glimpse on biological activities of tellurium compounds Anais da ABC (AABC)
Cunha,Rodrigo L. O. R.; Gouvea,Iuri E.; Juliano,Luiz.
Tellurium is a rare element which has been regarded as a toxic, non-essential trace element and its biological role is not clearly established to date. Besides of that, the biological effects of elemental tellurium and some of its inorganic and organic derivatives have been studied, leading to a set of interesting and promising applications. As an example, it can be highlighted the uses of alkali-metal tellurites and tellurates in microbiology, the antioxidant effects of organotellurides and diorganoditellurides and the immunomodulatory effects of the non-toxic inorganic tellurane, named AS-101, and the plethora of its uses. Inasmuch, the nascent applications of organic telluranes (organotelluranes) as protease inhibitors and its applications in disease...

A Global Model for Agriculture and Bioenergy: Application to Biofuel and Food Security in Peru and Tanzania AgEcon
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 globális gazdasági válság és a magyarországi agrárgazdaság kilátásai AgEcon
Magda, Sandor; Magda, Robert.
A tanulmány a globális pénzügyi és gazdasági válság klímaváltozás – fenntart¬hatóság – globalizáció rendszerébe illesztve olyan változásokat javasol – előnyt kovácsolva a kényszerből –, melyek számolnak a tényleges helyzettel és viszonylag kisebb áldozatokkal, valamint kockázattal megvalósíthatók. Ennek lényege tömören a termőföld-hasznosítás tudatos arányváltásai, a foglalkoztatás bővítése, integrációk szervezése és az oktatás korszerűsítése. Ajavasoltak nem veszélyeztetik hazánk élelmiszer-ellátásának biztonságát, de csökkentik az agrárágazatok, a vidék energiaköltségeit, energiafüggőségét, új munkahelyeket teremtenek, javítják a mezőgazdaságból és a vidéken élők anyagi körülményeit, hozzájárulnak az ország energiafüggőségének csökkenéséhez, így a...

A globalizáció és a konszolidációs számvitel alkalmazása a magyar élelmiszer-gazdaságban AgEcon
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 Government Decision Model for Invasive Species: Choosing the Most Efficient Government Program for the Management of Livestock Diseases AgEcon
Zhang, Yichen; Muhammad, Andrew; Coble, Keith H..
The impact of invasive species has grown substantially in recent years as evident by the trends in government expenditures in response to outbreaks. In this paper, authors analyze advantages and disadvantages of current government compensation measures for invasive species. The conceptual models are built to describe the relationship between producers’ utility and the effect of adoption of different measures under different observability condition. As a case study, a survey is designed to analyze producer behavior in mitigating AI & END outbreaks.

A gravity model approach to forecasting tuberculosis transmission in cattle AgEcon
Xie, Fang; Horan, Richard D.; Wolf, Christopher A..
Bovine tuberculosis (bTB) in cattle has caused significant economic losses to livestock producers and has proven difficult to eradicate. It is suspected that cattle movement across different farms and regions is one of the key factors of bTB transmission in the United States. Prior attempts to model the epidemiology of bTB infection within cattle to predict disease transmission have not adequately captured the behavioral aspects of trade. A better understanding of livestock trade patterns would help in predicting disease transmission and the associated economic effects. In this paper, we develop a gravity model of livestock trade and link it to an epidemiological model of bTB transmission, with the goal being that this information could lead to improved...
