"They Come, They Fish, and They Go:” EC Fisheries Agreements with Cape Verde and São Tomé e Príncipe
Resumo:
Fisheries agreements with the European Community (EC) are an important component of the fisheries sector in Cape Verde and São Tomé e Príncipe, constituting today a key source of income for the respective fisheries administration. In spite of this, and of the fact that these agreements have been renewed several times over the past decades, challenges remain in domains such as control and communication of fishing activities, follow-up of financial counterparts, and integration of European fleets’ operations with the Cape Verdean and Santomean economies. This paper analyzes the EC fisheries agreements with Cape Verde and São Tomé e Príncipe in terms of those domains, considering both the contents of the agreements and their practical implementation. The fisheries sector in each of these countries is reviewed, as are some of the fundamentals and criticisms of EC fisheries agreements. It is argued that the agreements with Cape Verde and São Tomé e Príncipe will not live up to the stated objectives of sustainability and responsibility in fisheries until improvements are made to the control of EC vessels, the follow-up of funds paid by the EC, and the size and diversity of benefits accruing to the fisheries and related sectors in the two countries

This paper describes how Bayesian updates of dialogue state can be used to build a bus information spoken dialogue system. The resulting system was deployed as part of the 2010 Spoken Dialogue Challenge. The purpose of this paper is to describe the system, and provide both simulated and human evaluations of its performance. In control tests by human users, the success rate of the system was 24.5% higher than the baseline Lets Go! system. ©2010 IEEE.

训练两只猕猴进行延缓GO/NO-GO任务操作。猴坐在定制的猴椅中,正前方40cm处放着计算机显示器。显示器下方装有一压板。猴按压板0.5s后,显示器屏幕右下角或左下角出现一白色方块信号(1.5cm×1.5cm),持续0.5s。这一信号为暗示信号。暗示信号消失后,延缓0.0-4.0s,然后在显示器屏幕的下方正中处出现一红色方块信号(1.5cm×1.5cm)。这一信号为反应信号。如果暗示信号出现在右边,则要求猴在0.8s内放开一直按着的压板(GO反应);如果暗示信号出现在左边,则要求猴继续按住压板1.2s(NO-GO反应)。正确操作后,猴得到一滴水的奖励。在这一行为任务中,延缓期内的短时工作记忆是“非空间表象”(non-spatiallyrepresentatioal)短时工作记忆。前额叶皮层背外侧部(Walket46区、9区)内注射α2受体拮抗剂yohimbine(10μg/2μl)使猴的任务操作正确率下降。延缓期越长,下降的幅度越大。注射Yohimbine后,猴的操作错误率升高主要表现在“交叉”反应率升高,即应该作GO反应时作NO-GO反应,反之亦然。注射α1受体桔抗剂Prazosin(10μg/2μl)或

在认知神经科学研究中,Go/NoGo模型是一种非常有效的研究方法。在本试验中,以两只猕猴为研究对象,采用Go/NoGo模型,以不同的视觉线索作为刺激来研究相关认知行为。结果表明猕猴能够很快学会Go/NoGo视觉分辨任务,而且对NoGo任务的完成要优于对Go任务的完成。本实验建立了一种有效的猕猴Go/NoGo视觉分辨实验的方法及计算机控制系统,为进一步记录神经元活动建立了良好的基础。

BACKGROUND: After investing significant amounts of time and money in conducting formal risk assessments, such as root cause analysis (RCA) or failure mode and effects analysis (FMEA), healthcare workers are left to their own devices in generating high-quality risk control options. They often experience difficulty in doing so, and tend toward an overreliance on administrative controls (the weakest category in the hierarchy of risk controls). This has important implications for patient safety and the cost effectiveness of risk management operations. This paper describes a before and after pilot study of the Generating Options for Active Risk Control (GO-ARC) technique, a novel tool to improve the quality of the risk control options generation process. OUTCOME MEASURES: The quantity, quality (using the three-tiered hierarchy of risk controls), variety, and novelty of risk controls generated. RESULTS: Use of the GO-ARC technique was associated with improvement on all measures. CONCLUSIONS: While this pilot study has some notable limitations, it appears that the GO-ARC technique improved the risk control options generation process. Further research is needed to confirm this finding. It is also important to note that improved risk control options are a necessary, but not sufficient, step toward the implementation of more robust risk controls.

Este trabalho apresenta resultados obtidos por simulação de sistemas para avaliação da dinâmica de alguns princípios ativos utilizados nas culturas de soja, milho e milho safrinha, cultivados no Município de Mineiros, GO, próxima a voçoroca Chitolina. Esta é uma das áreas de recarga do aqüífero Guarani e, quando exposta à agrotóxicos, requer um acompanhamento maior quanto ao risco de contaminação da água. A avaliação foi realizada nos principais tipos de solo da área, a saber: Latossolo Vermelho Distrófico psamítico (V01) e Neossolo Quartzarenico Órtico Típico (V07). Vinte dos 22 produtos comerciais utilizados na área, correspondendo a 16 princípios ativos, foram avaliados utilizando o simulador CMLS- 94. As tendências de risco potencial de contaminação da água pela exposição aos produtos aplicados foram avaliadas para um período de 3 anos consecutivos, assim como a influência da pluviosidade na lixiviação dos produtos. As prioridades de monitoramento ?in loco? foram apresentadas.

Com o objetivo de estudar as estrategias da agricultura familiar no Municipio de Silvania-GO foram testadas 22 variaveis relacionadas com o fluxo de caixa de 25 propriedades de uma rede de fazendas de referencia (RDF).As informacoes coletadas durante os anos 1992\\1993, 1993\\1994 e 1994\\1995 forneceram elementos para a caracterizacao do perfil dos sistemas de producao existentes naquele municipio. O estudo utilizou a analise fatorial de correspondencia, a classificacao hierarquica e a analise discriminante. A analise das variaveis que compoem o fluxo de caixa das propriedades da RDF permitiu identificar cinco estrategias adotadas pelos produtores. Duas dessas estrategias dizem respeito a forma de captacao de recursos para investimento na propriedade. A primeira delas ocorre pela venda de ativos financeiros, e a segunda ocorre pela tomada de emprestimos e financiamentos. As outras tres dizem respeito ao funcionamento dos sistemas de producao e sao definidas pela maior enfase na diversificacao, na pecuaria ou na transformacao de produtos.
