description: Using numerical simulations, we study the effects of magnetic resistivity and thermal conductivity in the dynamics and properties of solar jets with characteristics of Type II spicules and cool coronal jets. The dynamic evolution of the jets is governed by the resistive MHD equations with thermal conduction along the magnetic field lines on a 2.5D slice. The magnetic field configuration consists of two symmetric neighboring loops with opposite polarity, used to support reconnection and followed by the plasma jet formation. In total 10 simulations were carried out with different values of resistivity and thermal conductivity, that produce jets with different morphological and thermal properties we quantify. We find that an increase in magnetic resistivity does not produce significant effects on the morphology, velocity and temperature of the jets. However, thermal conductivity affects both temperature and morphology of the jets. In particular, thermal conductivity causes jets to reach greater heights and increases the temperature of the jet-apex. Also, heat flux maps indicate the jet-apex and corona interchange energy more efficiently than the body of the jet. These results could potentially open a new avenue for plasma diagnostics in the Sun's atmosphere.

description: This paper analyzes the demand for shrimp along with beef, pork, and chicken in the US food market, which contributes much to predicting supply strategies, consumer preferences and policy making. It focuses on the own and cross elasticity relationship between the expenditure share, price, and expenditure changes. An Almost Ideal Demand System (AIDs) model and two alternative specifications (both nonlinear AIDs and LA-AIDs) are used to estimate a system of expenditure share equations for ocean shrimp, penaeid shrimp, beef, pork, and chicken. Empirical results from nonlinear AIDs model is compared with those from LA-AIDs model. There are quite a few inconsistency between nonlinear and LA results. Results from nonlinear are more expected and more complied with microeconomic theory than those from LA. Also, results indicated that some insignificant slope coefficients and inappropriate signs of them did not comply with microeconomic theory. This could be caused by heteroscedasticity, autocorrelation, a limitation in the data used, or shrimp is a quite different commodity.

description: Objectivos: Este estudo teve como objetivo comparar ensaios de PCR em tempo real para deteção de C. fetus subsp. venerealis, o agente patogénico responsável pela campilobacteriose genital bovina, em 308 amostras prepuciais.


Materiais e métodos: A deteção ao nível da subespécie (C. fetus subsp. venerealis) foi avaliada em quatro ensaios de PCR em tempo real, dois direcionados para a sequência de inserção ISCfe1 e dois para o gene parA. A deteção ao nível da espécie (C. fetus) envolveu um ensaio direcionado para o gene nahE e um kit comercial de PCR em tempo real (LSI VetMAXTM C. fetus kit, Life Technologies).


Resultados: Na deteção ao nível da subespécie, os ensaios direcionados quer para diferentes alvos (parA e ISCfe1), quer para o mesmo alvo molecular mostraram uma elevada percentagem de resultados discordantes nas amostras analisadas. Por outro lado, todas as amostras positivas nestes ensaios (n=169) revelaram-se negativas nos ensaios de deteção de C. fetus, o que sugere a transferência horizontal destes alvos de subespécie para outras espécies bacterianas. A análise da discrepância entre os resultados obtidos na deteção dos alvos de espécie e subespécie levou à descoberta de uma nova espécie do género Campylobacter no prepúcio de touros, denominada de Campylobacter portucalensis. Foram isoladas três estirpes de C. portucalensis com sequências com elevada identidade com a sequência ISCfe1 e parA, as quais foram identificadas como responsáveis pelos resultados falso-positivos nos ensaios de deteção de C. fetus subsp. venerealis.


Conclusões: Este estudo demonstrou que os métodos moleculares direcionados para os alvos mais comumente usados na identificação de C. fetus subsp. venerealis, incluindo o gene parA e a sequência de inserção ISCfe1, podem originar uma elevada taxa de resultados falso-positivos. Esta falha de especificidade poderá dever-se à presença de sequências homólogas no genoma de outras espécies bacterianas, tal como foi evidenciado em C. portucalensis.

description: Country of Origin (COO) labeling has been shown in several studies to be an important extrinsic cue for consumers in their quality evaluation of food products such as olive oil. COO has not been discussed in the context of pepper; a spice which’s quality is highly dependant on its heritage. This is the first study that combines face-to-face interviews regarding attitudes, image and knowledge with a bind tasting of pepper and an investigation of consumer's WTP for pepper from different origins and processing characteristics. The study reveals that organic consumes are able to experience taste differences to due COO. They expect taste differences. But also concerned and involved consumers are not to that extent informed about COO that they rely in their purchase decision on COO information. As a result consumers are not willing to pay a significant higher price for COO labeled pepper.

description: Na reprodução equina, a falha gestacional acontece com alguma frequência causando uma grande perda económica e genética para a indústria equina. Como tal, a busca por outro tipo de terapia tem vindo a aumentar, destacando o uso da ozonoterapia. Esta, é uma medicina integrativa de baixo custo que tem vindo a demonstrar benefícios terapêuticos desde a Primeira Guerra Mundial até aos dias de hoje. Atualmente, existe literatura que afirma que o uso de lavagens intrauterinas com ozono tem sido uma opção muito benéfica para o tratamento de patologias reprodutivas tanto em mulheres como nos animais.


Objetivos: Com o presente estudo, pretendeu-se avaliar os efeitos da lavagem uterina com solução fisiológica ozonizada sobre as características citológicas e cultura microbiológica do líquido uterino em éguas com mais de 15 anos.


Materiais e Métodos: Para tal, fez-se a administração de solução fisiológica NaCL 0,9% ozonizada na concentração de 52 μg de O3/mL de oxigénio via uterina, recolhendo posteriormente o líquido administrado por gravidade, observando assim as características citológicas e os agentes microbianos presentes na cultura microbiológica.


Resultados: Observou-se um aumento momentâneo da inflamação durante o tratamento com ozono na maioria das éguas, porém, duas semanas após o procedimento, houve uma melhoria no grau de inflamação bem como na diminuição de agentes microbianos na cultura microbiológica.


Conclusão: Desta forma, conclui-se que a ozonoterapia pode ter um efeito terapêutico benéfico na redução do quadro de inflamação uterina, bem como no controlo de agentes microbianos, minimizando possíveis resistências bacterianas, adotando assim um papel importante no que toca à melhoria dos índices reprodutivos.

description: Coherent charge transport along ballistic paths can be introduced into graphene by Andreev reflection, for which an electron reflects from a superconducting contact as a hole, while a Cooper pair is transmitted. We use a liquid-helium cooled scanning gate microscope (SGM) to image Andreev reflection in graphene in the magnetic focusing regime, where carriers move along cyclotron orbits between contacts. Images of flow are obtained by deflecting carrier paths and displaying the resulting change in conductance. When electrons enter the the superconductor, Andreev-reflected holes leave for the collecting contact. To test the results, we destroy Andreev reflection with a large current and by heating above the critical temperature. In both cases, the reflected carriers change from holes to electrons.

Bactérias zoonóticas multirresistentes, numa perspetiva “One Health”

description: Atualmente, a resistência a antimicrobianos é uma das maiores ameaças em todo o mundo, afetando não apenas humanos e animais, mas também o meio ambiente. Bactérias multirresistentes (MDR), incluindo agentes patogénicos zoonóticos, podem ser transmitidos entre animais e humanos principalmente por contato direto, mas também indiretamente, através do meio ambiente ou do consumo de géneros alimentícios. As consequências para a saúde pública de bactérias MDR zoonóticas são invariavelmente difíceis de avaliar, pois a sua epidemiologia é altamente complexa, envolvendo a disseminação de resistência antimicrobiana e de determinantes de virulência, e consequentemente, levando à emergência e disseminação de clones bacterianos mais adaptados.


Na União Europeia (EU), de acordo com a Diretiva Zoonoses 2003/99/EC1, em todos os Estados Membros da UE (EM) é obrigatória a monitorização e recolha de informação relevante e, quando aplicável, dos dados comparáveis ​​sobre zoonoses, agentes zoonóticos, resistência antimicrobiana e de surtos de doença de origem alimentar. No entanto, em Portugal, esta recolha de dados é ainda escassa. No último ano, a FMV-ULHT e o INSA têm vindo a colaborar para responder a estas questões, tendo como foco os animais produtores de alimentos e os alimentos de origem animal como principais fontes de agentes zoonóticos causadores de doença no Homem e portadores de genes de resistência a antimicrobianos. Ao longo desta apresentação, iremos apresentar-vos alguns trabalhos de investigação decorrentes desta estreita colaboração, em que a comparação de isolados de origem animal, alimentar e humana é essencial para compreender as fontes e a dinâmica de transmissão dessas bactérias zoonóticas. A adoção de uma abordagem One Health é assim fundamental para identificar os fatores que contribuem para a emergência e persistência de bactérias MDR e estabelecer estratégias de controlo mais adequadas.

description: A substantial amount of time and energy has been invested to develop machine vision using connectionist (neural network) principles. Most of that work has been inspired by theories advanced by neuroscientists and behaviorists for how cortical systems store stimulus information. Those theories call for information flow through connections among several neuron populations, with the initial connections being random (or at least non-functional). Then the strength or location of connections are modified through training trials to achieve an effective output, such as the ability to identify an object. Those theories ignored the fact that animals that have no cortex, e.g., fish, can demonstrate visual skills that outpace the best neural network models. Neural circuits that allow for immediate effective vision and quick learning have been preprogrammed by hundreds of millions of years of evolution and the visual skills are available shortly after hatching. Cortical systems may be providing advanced image processing, but most likely are using design principles that had been proven effective in simpler systems. The present article provides a brief overview of retinal and cortical mechanisms for registering shape information, with the hope that it might contribute to the design of shape-encoding circuits that more closely match the mechanisms of biological vision.

description: The ability of a firm to differentiate their product hinges critically on an accurate understanding of the perceptions consumers hold regarding the implications of a credence labeling claim. Building upon existing work evaluating other food attribute labels (e.g., genetically-modified products, region of origin, use of growth hormones) and the impact of consumer inferences (e.g., implicit associations made from explicitly provided information), this work begins to address gaps in the literature regarding food products with sustainably produced claims. This paper uses data collected in the summer and fall of 2010 from a national, web-based survey of 1002 households, to initiate the process of examining consumer inferences and valuations of food products making sustainably produced claims. A Best-Worst scaling framework was implemented to identify what consumers believe sustainably produced labels mean and their preferences for each of the sustainable farming practices considered. The best-worst survey method forces respondents to make trade-offs by simultaneously choosing the most and least preferred attributes. The measured level of concern can then be applied to a standardized ratio scale. The results of this study suggest that consumers perceive farm size and local production as highly important elements of sustainable agriculture. Additionally, consumer preferences over economic attributes such as consumer food prices and financial stability of farmers exhibit high heterogeneity, indicating segmentation in the sample and potential for targeted marketing management.
“Who is there?” - Metagenómica no conceito “One Health” – identificar o invisível

description: É, nos dias de hoje, perfeitamente aceite que é fundamental não dissociar as vertentes humana, animal e ambiental quando se fala em Saúde. Em termos de doenças infeciosas, é por demais sabido que os agentes microbianos patogénicos, sejam eles bactérias, vírus, fungos ou parasitas, e respectivos genes de resistência a fármacos, circulam frequentemente nestes três “ambientes hospedeiros”, causando doença animal ou humana. Assim, nestes últimos anos têm-se encetado esforços no sentido de “mapear”, com a exactidão possível, a circulação destes agentes microbianos e marcadores de resistência, por forma a melhor controlar a infecção animal e humana.


O desenvolvimento da metodologia de sequenciação de nova geração (NGS) veio precisamente permitir, dado descodificar a sequência genética total de qualquer microrganismo, identificar com a máxima precisão os microrganismos isolados e os seus genes de resistência. No entanto, este procedimento requer a utilização prévia de meios de cultura selectivos por forma à obtenção de culturas puras de determinados microrganismos. Tratando-se por vezes de amostras complexas e não havendo qualquer pista sobre o tipo de microrganismo a pesquisar, isto implica a utilização de múltiplos meios de cultura por exemplo para bactérias e fungos e perde-se a informação dos microrganismos não cultiváveis em meios artificiais, como o caso dos vírus, que requerem métodos moleculares para a sua identificação.


A metagenómica, uma das mais importantes e promissoras vertentes da metodologia de NGS, surge assim como uma ferramenta com potencial para ultrapassar os obstáculos acima referidos. Trata-se de um método de detecção de material genómico de toda a comunidade microbiana em qualquer amostra, independentemente do seu grau de complexidade, não estando sujeita ao carácter cultivável dos microrganismos existentes. Permite, além disso, a detecção independente de genes de resistência a fármacos que a amostra possa conter. Este metodologia tendo sofrido, nos últimos anos, avanços consideráveis em termos de aumento de sensibilidade e redução de custos.


A metagenómica constitui assim uma das “metodologias de ponta” em maior desenvolvimento dado o seu potencial de detecção virtualmente ilimitado, sendo, por isso, frequentemente caracterizada com a expressão “Who is there?”.


Nesta apresentação, serão explicados os fundamentos da metagenómica, os seus avanços científicos e serão apresentados múltiplos exemplos da sua aplicação prática na detecção de bactérias, vírus, fungos e parasitas em amostras complexas como as fezes, biópsias e solos.

The integration of information technology and academic advising : a Canadian study
Creators: name: Delgatty, Elinor
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study is to identify key technologies in use within academic advising and student services and to investigate the impact that information technology is having on the delivery of academic advising services and the development of advising theory in Canadian universities. Information technology may include email, information based web-sites, electronic degree audit, internet based web-advising, student information databases and other user specific interfaces The premise for this study is that the use of technology in academic advising is increasing and is having an impact on the delivery of advising services by reducing the manual burden of information integration and dissemination, and enabling academic advisors to focus developmentally and holistically, focusing on the growth and improvement of students academically and personally. As a professional Academic Advisor my search of literature on information technology and academic advising revealed an absence of qualitative and quantitative information about the use of academic advising technology and its impact on the delivery of advising services. This study was conducted using a mixed model survey of professional academic advisors and advising administrators in Canada’s public four year English language research universities. Data analysis showed that while technology use is widespread within Canadian advising centres, that the goals, use and perceptions of technology vary. Many functions which could (and should) be managed efficiently by technology are still being performed manually and the implementation of information technology is not being done in coordination with an institutional retention plan or advising model in mind.

description: As developers debug, developers formulate hypotheses about the cause of the defect and gather evidence to test these hypotheses. To better understand the role of hypotheses in debugging, we conducted two studies. In a preliminary study, we found that, even with the benefit of modern internet resources, incorrect hypotheses can cause developers to investigate irrelevant information and block progress. We then conducted a controlled experiment where 20 developers debugged and recorded their hypotheses. We found that developers have few hypotheses, two per defect. Having a correct hypothesis early strongly predicted later success. We also studied the impact of two debugging aids: fault locations and potential hypotheses. Offering fault locations did not help developers formulate more correct hypotheses or debug more successfully. In contrast, offering potential hypotheses made developers six times more likely to succeed. These results demonstrate the potential of future debugging tools that enable finding and sharing relevant hypotheses.

description: Existing literature on the 2007/8 food price crisis focuses on the causes and poverty and hunger consequences of the crisis and seems to be less concerned with the interactions of different policy measures applied by governments. As such, the relative effectiveness, interactions and costs of these policy actions are often not satisfactorily explored. This paper provides a first preliminary quantitative assessment on the individual and joint effects of China’s short term trade policy actions and existing domestic support measures on domestic market prices, outputs, trade flows and farm income, using a global CGE model characterized with detailed and up-to-date policy information for China in the year of 2008. A series of interesting results emerge from our simulations. First, China’s agricultural outputs for many products are estimated to be boosted by up to 1.8 percentage by all the policy interventions combined, indicating that the extra domestic support in 2008 (relative to the pre-crisis level) is able to compensate for the lowered outputs due to the short term trade policy measures. The most stringent export restriction placed on wheat, however, reduces agricultural incentive so much that the observed domestic support measure is not able to compensate the lost domestic production. Second, while both the short term trade policy measures and existing domestic measures are able to reduce domestic market price, roughly two-thirds of the price reductions are due to the increased spending on the domestic measures. Third, the domestic market price reduction effects of the observed policy measures are shown to be large and significant, relative to the observed agriculture and food price indexes in China in 2008. Lastly, while China seems to be quite successful in tackling the food price inflation issue using a combination of policy measures, the fiscal and efficiency costs are not negligible, especially if one considers the extra government spending on the input subsidies necessitated by the insulating trade and border policy measures.

description: Objectives: The metalloprotease ADAM17 (also called TACE) plays fundamental roles during development, and to promote homeostasis and multiple inflammatory diseases and cancer by shedding key signaling molecules from the cell surface. Its importance in inflammation and growth control is well documented, while little is known about the role of ADAM17 and its regulator iRhom2 in metabolic homeostasis. The purpose of this study was to determine the impact of the sheddase ADAM17/TACE and of its modulator iRhom2 in the pathophysiology of obesity and in adipocyte homeostasis.


Materials and Methods: We challenged controls versus iRhom2 global KO or adipocyte specific ADAM17 KO mice to positive energy balance by chronic exposure to a high fat diet, and then compared their metabolic phenotypes. We also carried out ex vivo assays with primary and immortalized mouse brown and beige adipocytes to establish the autonomy of the effect of loss of iRhom2 and ADAM17 on differentiation, thermogenesis and respiration. In addition, we used proteomic and transcriptomic analyses to identify and characterize a novel ADAM17 substrate involved.


Results: iRhom2 global KO and adipocyte-specific ADAM17 KO mice exhibited a hypermetabolic phenotype characterized by elevated energy consumption and increased levels of adipocyte thermogenic gene expression and browning. This protected mutant mice from obesogenic challenge, limiting weight gain, hepatosteatosis and insulin resistance. Proteomic studies identified Semaphorin 4B (SEMA4B), as a novel ADAM17-shed adipokine, whose expression is regulated by physiological thermogenic cues, that acts to inhibit adipocyte differentiation and dampen thermogenic responses in adipocytes.


Conclusion: Our findings identify a novel iRhom2/ADAM17-dependent axis, regulated by beta-adrenoceptors and mediated by the ADAM17-cleaved form of SEMA4B, that modulates energy balance in adipocytes by inhibiting adipocyte differentiation, thermogenesis and lipid catabolism.

description: Innovation management looks different in a start-up company than it does in a large, multi-national enterprise. This thesis analyzes the evolution of innovation management throughout the life-cycle of companies. Five life-cycle stages existence, survival, success, renewal and decline - are studied for their implications to the elements of the innovation value chain: idea generation, conversion and diffusion. While some features are of importance in any stage, such as a corporate culture that supports creativity, risk-taking and entrepreneurial behavior, as well as the need for absorptive capacity to take-in external knowledge, some features are specific to certain stages. A start-up needs innovations that help commercialize the initial product for market-entry and has to shelf other ideas for later, creating the need for an idea repository. Growing companies have to develop innovation strategies and foresight policies, as well as processes to govern new product development (NPD), e.g. by introducing Stage-Gate processes. Large companies have to tackle the challenge of complexity, operating in various regions and markets, and must actively enforce the inter-departmental communication; but they have options like structural ambidexterity or formation of spin-off companies. Beyond these seemingly self-evident observations, this thesis provides a sort of “navigation system” for growing companies in order to set the right priorities at the right time and stay innovative throughout the life-cycle.

description: This paper presents a first empirical assessment of carnivore conservation under a performance payment scheme. The Swedish government issues payments to reindeer herder villages based on the number of carnivore offspring certified on their pastures. The villages decide on the internal use and distribution of the payments. It is generally assumed that benefit distribution rules are exogenously given. We develop a model to investigate such rules as endogenous decision. The empirical data reveals that villages’ group size has a direct negative effect on conservation outcomes. However, there is also an indirect positive effect which impacts conservation outcomes through the benefit distribution rule. This result revises the general collective action hypothesis on purely negative effects of group size. The paper concludes that if limited hunting is legal, conservation success strongly depends on villages’ potential for collective action and the benefit distribution rule they choose.

description: Objetivos: O objetivo deste trabalho foi testar a eficácia de um programa de treino na melhoria do condicionamento físico, com consequente aprimoramento do gasto energético (GE) e do custo de transporte (COT) em cavalos Puro-Sangue Lusitanos (PSL) utilizados em dressage.


Materiais e Métodos: Nove equinos foram avaliados antes (M1) e após seis semanas (M2) de um programa de treino de 40-80 min de exercícios de dressage, 6x/semana, ajustados individualmente. Em M1 e M2, os animais foram examinados antes (T0), imediatamente após (T1) e com 30min (T2) e 4h (T3) de recuperação do teste de simulação de dressage (TSD), quando foram registadas frequências cardíaca (FC) e respiratória (FR), temperatura corporal (TC) e lactato sanguíneo. Nos TSD, os cavalos utilizaram monitor cardíaco com GPS integrado (Polar M430) para posterior cálculo das seguintes fórmulas: GE (J/kg/min) = 0,0566 x FC1,9955, COT = (FC–35)/kg/m x103. Os dados obtidos foram submetidos a ANOVA, teste-t e teste de Tukey (p<0,05).


Resultados: O treino levou a redução significativa na FC e TC, entretanto, a FR e lactato sanguíneo aumentaram após as seis semanas de treino. Houve um aumento significativo na velocidade máxima em M2 (7,36 vs. 5,8 m/s; p=0,0161), sem alterações na FCmax (~158,1 bpm), FCmed (~113,9 bpm), e distância (~220 m). FC (121,7 vs. 114,0 bpm; p<0,001), GE (97,6 vs. 84,7 J/min; p<0,001) e COT (97,3 vs. 88,8 bpm/kg/m.103; p<0,001) reduziram significativamente após as seis semanas de treino.


Conclusões: O protocolo de treino foi eficiente na melhoria da condição física dos cavalos, pois houve maior eficiência dos custos de locomoção, com valores menores de GE e COT, após 6 semanas de treino. O uso do monitor cardíaco e posterior cálculo dos índices energéticos mostrou ser uma ferramenta útil e importante para a monitorização adequada de programas de treino e preparação de cavalos de desporto.

description: Algebraic effects are computational effects that can be described with a set of basic operations and equations between them. As many interesting effect handlers do not respect these equations, most approaches assume a trivial theory, sacrificing both reasoning power and safety. We present an alternative approach where the type system tracks equations that are observed in subparts of the program, yielding a sound and flexible logic, and paving a way for practical optimizations and reasoning tools.

description: The ground-state structural and electronic properties of ferroelectric BiFeO$_3$ are calculated using density functional theory within the local spin-density approximation and the LSDA+U method. The crystal structure is computed to be rhombohedral with space group $R3c$, and the electronic structure is found to be insulating and antiferromagnetic, both in excellent agreement with available experiments. A large ferroelectric polarization of 90-100 $μ$C/cm$^2$ is predicted, consistent with the large atomic displacements in the ferroelectric phase and with recent experimental reports, but differing by an order of magnitude from early experiments. One possible explanation is that the latter may have suffered from large leakage currents. However both past and contemporary measurements are shown to be consistent with the modern theory of polarization, suggesting that the range of reported polarizations may instead correspond to distinct switching paths in structural space. Modern measurements on well-characterized bulk samples are required to confirm this interpretation.

description: The growth of microfinance instruments has allowed millions of poor people around the world to receive small loans without collaterals and proof of their credibility, which would not be possible in the conventional financial institution. With the increasing number of refugees and displaced people in the MENA regions, a need for the Islamic microfinance products has notably grown. However, current Islamic banks rarely provide financial services to the poor. Accordingly, there is an urgent need to develop alternative financial instruments to respond to needs of the poor populations in the Middle East and to enhance the development of entrepreneurship in the region, which might contribute to the overall poverty alleviation. Within this paper a Shariah-compliant crowdfunding platform is elaborated and discussed in details. The study was conducted by using qualitative analysis of the secondary data. The results showed that crowdfunding instruments can be employed in different models, whereas one of the most compliant in terms of Islamic finance principles is investment-based with equity sharing method. Therefore, the paper proposes that the musharakah crowdfunding model in form of equity represents an effective alternative method for financing entrepreneurial activities and micro-enterprises, whereby overcoming the funding gap and potential risk expected by financial institutions and aiming at poverty reduction in the long term.

description: Current research evaluating biofuels policies focuses primarily on market-economic criteria. While it is widely acknowledged that both the economic and environmental, and social aspects of biofuels policy must all be balanced with each other in the process of developing a viable biofuels policy, little progress has been made to date on evaluating these uncertain non-market relationships. In this paper, we develop a fuzzy theory holistic approach evaluating the 1st, 2nd, and 3rd generation biofuels feedstocks in meeting multiple economic, environmental and social criteria of the biofuels policies and capturing the uncertainties of evaluation processes. We use a multi-criteria approach PROMETHEE (Preference Ranking Organization Method for Enrichment Evaluations) and fuzzy set theory to show how missing information, fuzziness, and ambiguity in decision making processes can be considered for a sustainable biofuels policy evaluation.

description: The National Economy for agricultural participation is high where the productive factor is necessary as key task for improving the productivity with the aim to increase the production and exportation food quantity. For this researching 48 agricultural bean farmers was been choosing in Masaya and Carazo with they a participative workshop was organized and with this input a survey was applied, then 4 Department Masaya farmers and 4 Department Carazo farmers were selected with the purpose of study them during the post agricultural period. 4 variables were defined, these are: absolute fertility, relative fertility, cost production, labour worker cost and bean capital. This analysis deduce that the large part of capacity and technical assistance gave to the small farmers was target to technical feature where the economic, social and organization topics don´t were considered. The results show that these small farmers had extensive productions to economic scale, consequently the unit production size, labour workers cost and capital weren´t enough factors for improve the productive (i.e. effective). Then the preponderance factor for small farmer development is the knowledge intensification.

description: We numerically analyze spectral properties of the Fibonacci model which is a one-dimensional quasiperiodic system. We find that the energy levels of this model have the distribution of the band widths $w$ obeys $P_B(w)\sim w^α$ $(w\to 0)$ and $P_B(w) \sim e^{-βw}$ $(w\to\infty)$, the gap distribution $P_G(s)\sim s^{-δ}$ $(s\to 0)$ ($α,β,δ>0$) . We also compare the results with those of multi-scale Cantor sets. We find qualitative differences between the spectra of the Fibonacci model and the multi-scale Cantor sets.

description: The study analyzes the trend and growth of total factor productivity in the Nicaragua livestock sector which is compare with secondary and tertiary subsectors for measuring employment and wage policy impact during 1994-2010 period. The available data’s Nicaragua Central Bank were used for estimating the Malmquist Index on that period. The study used Data Envelope Analysis (DEA) for productivity Malmquist Index derivation. The paper analyzes the primary, secondary and tertiary growth productivity trend in Nicaragua during the period studied. Either the catch-up and convergences issues or some possible divergences as study cases in agricultural productivity, industry and services are investigating think through global structure. The results are sharing with the IMAE (Economic Activity of Monthly Index) and the growth population rate for Nicaragua. The mean TFP was 5.5 percent where the primary sector shows a 4.4 percent by below secondary and tertiary sector 7.3 percent respectability. These changes were mainly caused by the technology change that reached a mean of 5.6 percent, while the technical efficiency change was indifferent for workers employed. This result reveals the importance that Malmquist Index have for using as complement IMAE index where the policy maker may consider it as input in yours decision.
