Implementação de Visualização de Dados Tridimensionais de Malhas Irregulares no Processador Cell Broadband Engine.

A renderização de volume direta tornou-se uma técnica popular para visualização volumétrica de dados extraídos de fontes como simulações científicas, funções analíticas, scanners médicos, entre outras. Algoritmos de renderização de volume, como o raycasting, produzem imagens de alta qualidade. O seu uso, contudo, é limitado devido à alta demanda de processamento computacional e o alto uso de memória. Nesse trabalho, propomos uma nova implementação do algoritmo de raycasting que aproveita a arquitetura altamente paralela do processador Cell Broadband Engine, com seus 9 núcleos heterogêneos, que permitem renderização eficiente em malhas irregulares de dados. O poder computacional do processador Cell BE demanda um modelo de programação diferente. Aplicações precisam ser reescritas para explorar o potencial completo do processador Cell, que requer o uso de multithreading e código vetorizado. Em nossa abordagem, enfrentamos esse problema distribuindo a computação de cada raio incidente nas faces visíveis do volume entre os núcleos do processador, e vetorizando as operações da integral de iluminação em cada um. Os resultados experimentais mostram que podemos obter bons speedups reduzindo o tempo total de renderização de forma significativa.

Tempo Integral e Educação Integral: um estudo sobre a experiência de Nova Iguaçu de 2006 a 2013

Esta pesquisa analisa as perspectivas adotadas para uma educação integral implementadas pela cidade de Nova Iguaçu no período de 2006 a 2013, mais especificamente tendo em tela a implementação do Programa Bairro-Escola (2006 a 2010) e o Programa Mais Educação (2008 a 2013) oriundo do governo federal. A partir do conceito de educação integral como uma perspectiva de aprendizagem/apreensão de experiências e conhecimentos complementares fundamentados no social, em um contexto de relações histórico-sociais foi possível revisitar os Programas Bairro-Escola e o Programa Mais Educação. Foram consideradas as concepções de tempo integral e educação integral dos autores Coelho (1997, 2009, 2012), Cavaliere (2002, 2007, 2009, 2010) e Algebaile (2004, 2009, 2013). A metodologia adotada considerou a pesquisa qualitativa valendo-se de pesquisa documental, analisando a legislação das esferas governamentais, manuais e orientações municipais, utilizando o Ciclo de Políticas de Ball & Bowe (1992), baseado nos estudos de Mainardes (2006). A luz das reflexões permeadas pelas concepções sócio historicamente referenciada e a de proteção social, em suas especificidades, pode-se considerar os aspectos da apropriação da cultura e da ciência acumuladas historicamente, como condição para atuação protagonizadora à reorganização crítica de tal cultura e ciência, como também a visão considerada como acolhimento e integração social, atendendo primordialmente, a missões sociais de apoio à criança. O resultado do estudo remete a constatação de que a iniciativa do Programa Bairro-Escola diferentemente da proposta de uma educação integral em tempo integral do Programa Mais Educação, constituiu-se em um programa ousado e significativo e caracterizou-se em uma visão moderna de acordo com seus propósitos de educação integral. O Programa Bairro-Escola em sua formulação apresenta tendência de uma educação integral com vistas a uma formação socialmente partícipe, contextualizada no momento histórico e ofertada a todos, já o Programa Mais Educação apresenta tendências de uma rede de proteção social limitando-se ao atendimento de crianças e adolescentes em situações de vulnerabilidade social.

Getting it right: incorporating social aspects into MPA planning and implementation

This brochure summarizes a series of case studies done in nine countries—Brazil, India, Indonesia, Mexico, Senegal, South Africa, Spain,Tanzania and Thailand—on the role of communities in the planning and implementation of marine protected areas (MPAs). The studies demonstrate that communities can be powerful allies in efforts for conservation and management of coastal and marine resources. They also underline the need for systematic attention, capacity building, funding and other resources for effective implementation of Programme Element 2 on governance, participation, equity, and benefit sharing of the Programme of Work on Protected Areas (PoWPA) of the Convention on Biological Diversity (CBD).

International legal instruments relevant to fisheries and fishing communities : a handbook. Introduction

This handbook provides detailed information for a wide range of legal instruments relevant to fisheries and fishworkers. It covers 114 legal instruments, categorized into the following seven themes: Theme I. Human Rights, Food Security, Women and Development. Theme II. Environment and Sustainable Development. Theme III. Oceans and Fisheries Management. Theme IV. Environmental Pollution Theme V. Fishing Vessels and Safety at Sea Theme VI. Labour Theme VII. Trade The handbook also includes the working of the instruments (decision-making bodies, monitoring and implementation agencies, periodicity of meetings, rules for participation in meetings of the decision-making bodies and implementation agencies for States and non-governmental organizations), regional instrument and agencies. Apart from being a ready reckoner to the instruments, it highlights the important sections of relevance to fisheries or small-scale fisheries and fishworkers. The companion CD-ROM provides the full texts of the instruments in a searchable database. The handbook will be useful for fishworker and non-governmental organizations, and also for researchers and others interested in fisheries issues.
