Investing in Africa: the WorldFish Center's African strategy in summary

Across much of Africa, freshwater and coastal fisheries provide an important source of food and livelihood for many millions of people. In addition, the aquaculture potential of the continent has only recently begun to be developed. To help sustain these capture fisheries, support the emergence of aquaculture and foster the contribution of both to sustainable livelihoods and improved food security, the WorldFish Center is increasing its investment in Africa. The framework for this investment is provided by a new Strategy for Africa and West Asia 2002-2006 that identifies priorities for the Center’s work in rivers and floodplains, lakes and reservoirs, coastal fisheries, aquaculture, policy research and capacity building. The present article summarizes the issues being addressed by the Center and describes initial research priorities.

Traditional institutions and their role in the contemporary coastal resource management in the Pacific Islands

A discussion is presented on the role played by customary marine tenure (CMT) institutions in the regulation of fisheries in the Pacific Ocean Islands. Particular reference is made to the system in operation in Marovo Lagoon, in the Solomon Islands, whereby a number of defined clans control resource use within defined areas of land and sea. It is believed that such systems have considerable capacity for handling and adapting to new circumstances, thereby becoming potentially important tools in the contemporary management of fisheries and of the coastal zone in general.

Transgene expressions in seabass (Lates calcarifer) following muscular injection of plasmid DNA: a strategy for vaccine development?

Muscular injection has become one of the direct methods for transferring foreign DNA into organisms. The technique has been recently introduced in the development of vaccines and gene therapy. Vaccine development, in particular, would be desirable in managing viral diseases in farmed fish. In this study, the technique was performed on seabass (Lates calcarifer) and was found that the foreign gene could be transferred successfully through injection into the muscles.

Escritor-personagem / personagem-escritor: Daniel Galera e o projeto Amores Expressos

Diante da recorrência da criação de personagens-escritores nas obras brasileiras de ficção publicadas a partir dos anos 1990, foi escolhida a produção de Daniel Galera como estudo de caso. O personagem-escritor foi observado como estratégia para discutir questões relativas à cena literária contemporânea. Foi delimitado como corpus dessa pesquisa o blog criado durante a estada de Daniel Galera em Buenos Aires, ao participar do projeto Amores Expressos, e o romance Cordilheira (2008), escrito como fruto dessa experiência. Tendo em vista a trajetória de sua carreira em constante relação com a internet, foi analisada a construção do escritor-personagem no blog hospedado no site do projeto, em contraponto à figura do personagem-escritor no romance. Para tanto, foram utilizados textos sobre a autoficção, a performance e a autoria. Na comparação dos textos de ambos os suportes, foram evidenciadas semelhanças e diferenças nas problematizações a respeito da formação do autor. Foi investigada a inserção de trechos do blog no romance como estratégia que oferece complexidade nos espelhamentos das imagens e enriquece os efeitos de leitura do romance

The National Marine Fisheries Service’s National Bycatch Strategy

The National Marine Fisheries Service (NMFS) launched its National Bycatch Strategy (NBS) in March 2003 in response to the continued fisheries management challenge posed by fisheries bycatch. NMFS has several strong mandates for fish and protected species bycatch reduction, including the Magnuson-Stevens Fishery Conservation and Management Act, the Endangered Species Act, and the Marine Mammal Protection Act. Despite efforts to address bycatch during the 1990’s, NMFS was petitioned in 2002 to count, cap, and control bycatch. The NBS initiated as part of NMFS’s response to the petition for rulemaking contained six components: 1) assess bycatch progress, 2) develop an approach to standardized bycatch reporting methodology, 3) develop bycatch implementation plans, 4) undertake education and outreach, 5) develop new international approaches to bycatch, and 6) identify new funding requirements. The definition of bycatch for the purposes of the NBS proved to be a contentious issue for NMFS, but steady progress is being made by the agency and its partners to minimize bycatch to the extent practicable.

Singapore's biomedical science sector development strategy: is it sustainable?

This paper outlines the strategic efforts undertaken by Singapore to establish its national capability in the biomedical science sector, reviews the commercial base as a result of these efforts and compares Singapore's approach to the UK and the US development models, discusses the challenges that Singapore faces and raises some questions on the long term sustainability of the sector.

Background Concepts for a Rotating Harvesting Strategy with Particular Reference to the Mediterranean Red Coral, Corallium rubrum

A simple cohort model was used as the basis for selecting the appropriate periodicity and number of separate unit areas in a rotating harvest scheme for a sedentary species, the red coral, Corallium rubrum, in the General Fisheries Management Council for the Mediterranean area. The rotation period in years, and hence the minimum number of unit areas involved, was determined on the basis of the time to maximum biomass by a simple calculation of the yield-per-recruit type, requiring a knowledge of natural mortality and growth rates. Other criteria may be more important, however, and in general for a long-lived species, will result in shorter rotation periods. These criteria may include economic factors, criteria based on the preferred size or quality of product, or criteria that take into account the cumulative risk of illegal fishing of closed areas with time, hence the growing cost of enforcement as harvestable product accumulates. For red coral, although maximum biomass is predicted to be reached after some 15-44 years, the above considerations suggest that a rotation period ofsome 9-15 years would be close to optimal, taking into account a range ofthe above considerations. This article discusses the relative merits of rotating harvest schemes in contrast to quota management for sedentary and semi-sedentary resources or geographically isolated substocks ofa mobile resource, and concludes that this approach may have considerable potential as an alternative approach to resource management.

A impossibilidade do esvaziamento pleno: uma análise do vazio na arte

Tendo como objetivo principal destrinchar o conceito do vazio e a forma como este permeou a produção artística e o pensamento humano ao longo dos tempos, esta pesquisa faz uma incursão por teorias filosóficas desde a Antiguidade Clássica ocidental até conceitos filosóficos e religiosos do Oriente, a fim de compreender como o interesse pela ideia de vazio migrou para a produção artística e, mais do que isso, consolidou-se como um importante fundamento para a Arte Moderna e para a produção contemporânea. Partindo de exemplos e momentos da História da Arte que permitam a compreensão das várias formas como o pensamento artístico incorporou o conceito nas obras de arte, a partir desta primeira busca histórica e conceitual, será feita uma investigação pela produção de artistas visuais cujas trajetórias foram marcadas por ideias de esvaziamento. Num segundo momento, uma análise da 28 Bienal de São Paulo cujo eixo curatorial manteve todo um pavimento vazio durante o período expositivo buscará compreender a forma como a presença do vazio pode se ampliar para além do objeto artístico e se incorporar ao próprio espaço institucional
