Fisheries rules and regulations in 23 states of Nigeria: a note

In order to make a sound proposal to the Kainji Lake Fisheries Management and Conservation Unit regarding the amendment of the existing Fisheries Laws and Regulations, including the raise of fishing license fees, the Fisheries Departments of 21 Nigerian States were visited in August-September 2000. In that occasion the staff was interviewed, existing documents were revised, and the results were compared with those of Kebbi and Niger State

Applying Habermas's critical theory to public administration and policy: A case study of Florida Everglades restoration program

The foundation of Habermas's argument, a leading critical theorist, lies in the unequal distribution of wealth across society. He states that in an advanced capitalist society, the possibility of a crisis has shifted from the economic and political spheres to the legitimation system. Legitimation crises increase the more government intervenes into the economy (market) and the "simultaneous political enfranchisement of almost the entire adult population" (Holub, 1991, p. 88). The reason for this increase is because policymakers in advanced capitalist democracies are caught between conflicting imperatives: they are expected to serve the interests of their nation as a whole, but they must prop up an economic system that benefits the wealthy at the expense of most workers and the environment. Habermas argues that the driving force in history is an expectation, built into the nature of language, that norms, laws, and institutions will serve the interests of the entire population and not just those of a special group. In his view, policy makers in capitalist societies are having to fend off this expectation by simultaneously correcting some of the inequities of the market, denying that they have control over people's economic circumstances, and defending the market as an equitable allocator of income. (deHaven-Smith, 1988, p. 14). Critical theory suggests that this contradiction will be reflected in Everglades policy by communicative narratives that suppress and conceal tensions between environmental and economic priorities. Habermas’ Legitimation Crisis states that political actors use various symbols, ideologies, narratives, and language to engage the public and avoid a legitimation crisis. These influences not only manipulate the general population into desiring what has been manufactured for them, but also leave them feeling unfulfilled and alienated. Also known as false reconciliation, the public's view of society as rational, and "conductive to human freedom and happiness" is altered to become deeply irrational and an obstacle to the desired freedom and happiness (Finlayson, 2005, p. 5). These obstacles and irrationalities give rise to potential crises in the society. Government's increasing involvement in Everglades under advanced capitalism leads to Habermas's four crises: economic/environmental, rationality, legitimation, and motivation. These crises are occurring simultaneously, work in conjunction with each other, and arise when a principle of organization is challenged by increased production needs (deHaven-Smith, 1988). Habermas states that governments use narratives in an attempt to rationalize, legitimize, obscure, and conceal its actions under advanced capitalism. Although there have been many narratives told throughout the history of the Everglades (such as the Everglades was a wilderness that was valued as a wasteland in its natural state), the most recent narrative, “Everglades Restoration”, is the focus of this paper.(PDF contains 4 pages)

Fishery management plans and the development of artisanal fisheries in Nigeria: a review

Management of natural resources all over the world is of paramount importance to their sustainability in developing countries like Nigeria, there is less emphasis on proper management especially of fishery and other aquatic resources due to lack of sensitization and enlightenment of the rural dwellers who are closer to such natural resources. The main thrust of this review is to examine the management plans for Nigerian freshwater bodies (rivers and lakes) and the impact of such plans on the artisanal fisheries development in Nigeria. From the on-shelf information gathered there is scarcity of information on the management of Nigerian freshwater body's information available indicates that there is the traditional fisheries management and the government legal approach in form of fisheries Laws and Regulations. However, these management techniques are poorly carried out since there is a poor follow-up. Appreciable impact of fisheries management introduced on Kanji Lake by the Nigerian-German Kanji Lake Fisheries Promotion Project (NGKLFPP) between 1993 and 2001 proves worthwhile as this introduced some management measures such as implementation of fisheries Laws and Regulations, the ban of obnoxious fishing methods, introduction of fishing license, constitution of a management unit and appointment of liaison fishermen. Within the operative years of the project a lot of success was achieved and it is recommended that the approach in Kainji should be replicated in other freshwater bodies in Nigeria to alleviate poverty in the rural poor fishing communities

Management of inland capture fisheries and challenges in fish production in Nigeria

The paper critically examines the trend in fish production in Nigeria. The problem of excessive mismanagement and lack of attention by relevant agencies are still common place in inland water bodies. The paper discusses these mismanagement practices which are non compliance with the existing rules and regulations on good fishing methods, uncontrollable, unorthodox and obnoxious fishing practices, destruction of the natural breeding grounds and the collapse of the fishery due to massive over fishing. The challenges posed by the fishing methods as well as the effect of different gears and mechanization of fishing crafts on fish production are discussed. The paper recommends ways to increase domestic fish production in inland water bodies, which include a well planned strategy of restocking the existing reservoirs after careful scientific study, enforcement of the existing laws and regulation based on community participation. Training of stakeholders on the code of practice for responsible fisheries (CPRF), extension of subsidies to fisher folks, the traditional practices, which encourage the adherence to close season and other fish conservation and utilization strategies, are also advocated

O papel do Estado no controle territorial e sua relação com a estruturação atividade pesqueira brasileira na Primeira República

No início do século XX, a pesca tornou-se uma atividade de importância ressaltada pelo Estado. A Marinha propôs mudanças na legislação, para regionalizar a atividade e legalizar a vida profissional do pescador, o qual adquiriu uma cidadania maior que a de boa parte da população do período da Primeira República. Deve-se ressaltar que só foi possível estruturar assim a atividade pesqueira, porque anteriormente, no período imperial, houve uma longa preparação, a qual, nos fins do século XIX, já na Primeira República, culminou em o Estado compenetrar-se de que precisava conhecer e controlar os recursos naturais e sociais brasileiros. A estruturação politico-administrativa da pesca ocorreu criando-se a Confederação de Pesca e as federações estaduais, com suas colônias de pesca em todo Brasil. A finalidade era marcar o território com estruturas fixas que rganizassem os pescadores em comunidades e permitissem ao Estado controlar a produção nacional de pescado. Neste contexto, caberia a Marinha formar uma reserva naval composta por pescadores que pudesse ser facilmente arregimentados para garantir a defesa naval brasileira em situações de guerra. Neste sentido, a presente dissertação tem por objeto tanto organizar as informações acerca de como atividade pesqueira foi estruturada pelas legislações e pelos relatos da expedição que lhe fundou e organizou a estrutura nacional no Brasil, quanto mostrar a necessidade do Estado de conhecer melhor o seu próprio território e de identificar os potenciais da economia da pesca. A dissertação visa também salientar como essas mudanças vieram a influir, durante a Primeira República, sobre os deveres e direitos dos pescadores, e de que modo tais direitos e deveres contrastavam com os do restante do povo brasileiro.

A regulação das patentes farmacêuticas no Brasil: entre saúde pública, política e direito

O objetivo geral da tese é aprofundar a reflexão sobre a regulação e o exame de qualidade de patentes farmacêuticas no Brasil, em um contexto de implantação de dispositivos legais conhecidos como TRIPS-Plus ao redor do mundo. Para isso, são discutidos os mecanismos jurídicos e políticos de proteção à saúde relacionados à propriedade intelectual. Analisam-se especificamente do ponto de vista sociológico as experiências de anuência prévia para pedidos de patentes envolvendo produtos e processos farmacêuticos da Agência Nacional de Vigilância Sanitária (Anvisa) e o uso do subsídio ao exame técnico. Em termos metodológicos, consideram-se as ações do Governo brasileiro entre 1996 a 2012, propostas de mudança da Lei de Propriedade Industrial brasileira e controvérsias ligadas a algumas modalidades de reivindicação, como polimorfos, patentes de seleção e segundo uso médico. As técnicas de pesquisa utilizadas também incluem o levantamento de material de imprensa, textos de leis, documentos e decretos relativos a medicamentos e propriedade intelectual, assim como de pedidos de patentes e de decisões judiciais concernindo à temática. Optou-se ainda por realizar entrevistas com gestores, examinadores de patentes, juristas e membros de ONGs. As conclusões indicam que as práticas regulatórias ligadas ao setor saúde não podem ser reduzidas ao simples corpo de regras formais presentes neste domínio, mas sim entendidas como agenciamentos entre atores, tipos distintos de saberes e de ferramentas de intervenção. A regulação dos direitos de propriedade intelectual relativos a produtos e processos farmacêuticos no Brasil está ligada a um processo, onde se verifica a disputa em torno de diferentes projetos e visões de mundo de grupos com maior ou menor poder para direcionar este processo. Os dispositivos da anuência prévia e do subsídio ao exame técnico apresentam-se como elementos reguladores da propriedade intelectual de medicamentos e de impacto sobre exame de qualidade de patentes farmacêuticas, contribuindo para a consideração de questões de saúde pública ao longo da concessão destas patentes.

No evidence of bias from fish behavior in the selectivity of size and sex of the protogynous red porgy (Pagrus pagrus, Sparidae) by hook-and-line gear

Most fisheries select the size of fish to be caught (are size selective), and many factors, including gear, market demands, species distributions, fishery laws, and the behavior of both fishermen and fish, can contribute to that selectivity. Most fishing gear is size-selective and some, such as gill nets, are more so than others. The targeting behavior of fishermen is another key reason commercial and recreational fisheries tend to be size-selective. The more successful fishermen constantly seek areas and methods that yield larger or more profitable sizes of fish. Fishery regulations, especially size limits, produce size-selective harvests. Another factor with the potential to cause selectivity in a hook-and-line fishery is the different behavioral responses of fish to the bait or lure, whether the different responses arise among different fish sizes or between the sexes.

Genetic enhancement and conservation of aquatic biodiversity in Africa

There is a pressing need to enhance fish production in Africa through improved farm management and the use of improved fish breeds and/or alien species in aquaculture while at the same time conserve the aquatic genetic diversity. This paper presents the outcome of the Expert Consultation on Biosafety and Environmental Impact of Genetic Enhancement and Introduction of Improved Tilapia Strains/Alien Species in Africa held in Nairobi, Kenya on 20-23 February 2002. The main topics discussed were status of aquaculture in Africa and the role of genetic enhancement; potential benefits and risks involved in introduction of genetically improved strains and/or alien species with specific reference to tilapias; existing policies and legislation for the conservation of biodiversity, their strengths and weaknesses; capacity for undertaking genetic enhancement research and implementation of policies for the conservation of aquatic biodiversity.

Gestão de saúde, meio ambiente, segurança e responsabilidade social em micro e pequenas empresas de alimentos no município do Rio de Janeiro

O setor industrial de alimentos é um setor muito importante para a economia brasileira, segundo dados da Associação Brasileira das Indústrias da Alimentação (ABIA). Os diferentes produtos gerados pelas indústrias alimentícias são atribuídos a várias setores, como por exemplo, o setor de Food Service, o qual utiliza os insumos provenientes das indústrias de alimentos e fornecem alimentos prontos para os consumidores que buscam refeições fora dos seus lares. Devido à grande expansão desse setor, a exigência da sociedade por um sistema de Gestão em Saúde, Meio Ambiente, Segurança e Responsabilidade Social (SMS/RS) é grande, pois há preocupações ambientais, como o desperdício e a geração de resíduos, preocupações com as condições de trabalho dos funcionários, associados aos riscos e perigos no ambiente de trabalho e preocupações com as exigências legais, como o cumprimento de leis e normas na produção de alimentos, a fim de reduzir os riscos à saúde por doenças transmitidas por alimentos, com a segurança do mesmo. O objetivo geral desse estudo é avaliar as questões relacionadas à saúde, segurança, meio ambiente, sustentabilidade e responsabilidade socioambiental, de forma a verificar o nível de comprometimento dos serviços de alimentação micro e de pequeno porte no município do Rio de janeiro, com destaque para o atendimento ao serviço da Agência Nacional de Vigilância Sanitária (ANVISA), à legislação ambiental e de saúde e segurança no trabalho. Para atingir tal objetivo, a metodologia foi dividida em: pesquisa bibliográfica, elaboração de lista de verificação, questionário direcionado para os responsáveis e funcionários dos estabelecimentos, de questionário SMS/RS e visitas técnicas. Os resultados obtidos mostraram que, numa avaliação global, os trinta serviços de alimentação atenderam a todos os itens avaliados com relação à legislação sanitária e 88% no que tange aos aspectos de saúde, meio ambiente, segurança e responsabilidade social. Apesar de a legislação em saúde e segurança, meio ambiente e responsabilidade social ser uma prática comum nas micro e pequenas empresas fornecedoras de alimentos, em nenhuma delas foi implantado um sistema de Gestão baseado nessas questões, devido a falta de conhecimento por parte dos proprietários dos estabelecimentos

Links between energy dissipation and wear mechanisms in solid epoxy/epoxy sliding contact

This paper covers wear and energy dissipation of solid epoxy induced by the alternative rubbing between two samples of identical thermosetting polymer. Varying normal load, sliding velocity and sliding distance, the authors were able to define and discuss wear and friction laws and associated energy dissipation. Moreover, traces of several wear mechanisms were distinguished on the worn surfaces and associated with applied conditions. Observed under higher velocity, polymer softening and local state transition were explained by surface temperature estimate and confirmed by infra-red spectroscopy measurements. To conclude this study, all observed phenomena are classified into two wear scenarios according to sliding velocity. © 2014 Elsevier Ltd.

Persistent organic pollutant residues in the sediments and mollusks from the Bohai Sea coastal areas, North China: An overview

The Bohai Sea costal area is one of the most developed zones of China and the sewage water from populous and developed cities, including Beijing, Tianjin. Qinhuangdao and Dalian is discharged into the Bohai Sea. Additionally, its semi-enclosed characteristic restricts water exchange, which leads to high accumulation of pollutants in the environment. This overview presents the residues of 6 classes of Persistent Organic Pollutants (POPs). including PAHs, DDTs. HCHs, PCBs and PCDD/Fs. in the sediments and mollusks of the Bohai Sea through analyzing previous literatures. In the sediments. the highest PAH concentrations were detected in the vicinities of Qinhuangdao, while the northeast corner of the Bohai Bay possessed the highest levels of DDTs and PCBs. The investigations on HCHs and PCDD/Fs distributions on the whole sea scale have not been reported. In mollusks, PAH concentrations were in the same order of magnitude in the whole Bohai Sea, so were DDTs. HCHs and PCBs, while the outlier maximum values of PCDDs and PCDFs occurred in Yingkou. In general, the POPs residues in mollusks collected from Shandong Province were higher than the other areas. The compositions of DDTs, HCHs and PCBs in sediments indicated their recent usage. By comparing POP concentrations in sediments with the recommended criterions, it was shown that some individual PAH compounds occasionally associated with adverse biological effects in the vicinities of the Liaodong Bay and Qinhuangdao, and the Liaohe River Estuary were heavily contaminated with DDTs, but PCBs were all below the thresholds. In order to reveal the transference and transformation of POPs in the environment, further studies concerning with their behavior, fate and bioaccumulation in the different trophic levels should be programmed. Moreover, laws and regulations should be enforced to ban the illegal usage of POPs-containing pesticides to guarantee health of the environment and human. (C) 2008 Elsevier Ltd. All rights reserved.

Cortical Dynamics of Visual Motion Perception: Short-Range and Long Range Apparent Motion

This article describes further evidence for a new neural network theory of biological motion perception that is called a Motion Boundary Contour System. This theory clarifies why parallel streams Vl-> V2 and Vl-> MT exist for static form and motion form processing among the areas Vl, V2, and MT of visual cortex. The Motion Boundary Contour System consists of several parallel copies, such that each copy is activated by a different range of receptive field sizes. Each copy is further subdivided into two hierarchically organized subsystems: a Motion Oriented Contrast Filter, or MOC Filter, for preprocessing moving images; and a Cooperative-Competitive Feedback Loop, or CC Loop, for generating emergent boundary segmentations of the filtered signals. The present article uses the MOC Filter to explain a variety of classical and recent data about short-range and long-range apparent motion percepts that have not yet been explained by alternative models. These data include split motion; reverse-contrast gamma motion; delta motion; visual inertia; group motion in response to a reverse-contrast Ternus display at short interstimulus intervals; speed-up of motion velocity as interfiash distance increases or flash duration decreases; dependence of the transition from element motion to group motion on stimulus duration and size; various classical dependencies between flash duration, spatial separation, interstimulus interval, and motion threshold known as Korte's Laws; and dependence of motion strength on stimulus orientation and spatial frequency. These results supplement earlier explanations by the model of apparent motion data that other models have not explained; a recent proposed solution of the global aperture problem, including explanations of motion capture and induced motion; an explanation of how parallel cortical systems for static form perception and motion form perception may develop, including a demonstration that these parallel systems are variations on a common cortical design; an explanation of why the geometries of static form and motion form differ, in particular why opposite orientations differ by 90°, whereas opposite directions differ by 180°, and why a cortical stream Vl -> V2 -> MT is needed; and a summary of how the main properties of other motion perception models can be assimilated into different parts of the Motion Boundary Contour System design.

The analytical approach of the European Court of Human Rights in surveillance cases—the implications, justifications, and future of the Court’s reasoning, with a focus on the legislative impact in Ireland

A notable feature of the surveillance case law of the European Court of Human Rights has been the tendency of the Court to focus on the “in accordance with the law” aspect of the Article 8 ECHR inquiry. This focus has been the subject of some criticism, but the impact of this approach on the manner in which domestic surveillance legislation has been formulated in the Party States has received little scholarly attention. This thesis addresses that gap in the literature through its consideration of the Interception of Postal Packets and Telecommunications Messages (Regulation) Act, 1993 and the Criminal Justice (Surveillance) Act, 2009. While both Acts provide several of the safeguards endorsed by the European Court of Human Rights, this thesis finds that they suffer from a number of crucial weaknesses that undermine the protection of privacy. This thesis demonstrates how the focus of the European Court of Human Rights on the “in accordance with the law” test has resulted in some positive legislative change. Notwithstanding this fact, it is maintained that the legality approach has gained prominence at the expense of a full consideration of the “necessary in a democratic society” inquiry. This has resulted in superficial legislative responses at the domestic level, including from the Irish government. Notably, through the examination of a number of more recent cases, this project discerns a significant alteration in the interpretive approach adopted by the European Court of Human Rights regarding the application of the necessity test. The implications of this development are considered and the outlook for Irish surveillance legislation is assessed.

Impact of the smoke-free workplace legislation on smoking behaviour, risk perception & stigmatisation

The Republic of Ireland became the first European country to implement nationwide smoke-free workplace legislation. Aims: To determine prevalence of smoking among bar workers and estimate the impact of the smoke-free workplace legislation on their smoking behaviour to that of a comparable general population sample. To approximate the influence of tobacco control measures on risk perception of second-hand smoke (SHS) among the general population. To explore the de-normalisation of smoking behaviour and the potential increased stigmatisation of smokers and their smoking. Methods: Prevalence estimates and behavioural changes were examined among a random sample of bar workers before and 1 year after the smoke-free legislation; comparisons made with a general population sub-sample. Changes in risk knowledge related to SHS exposure were based on general population data. Qualitative interviews were conducted among a purposive sample of smokers and non-smokers four years after the implementation of the legislation. Results: Smoking prevalence was extremely high among bar workers. Smoking prevalence dropped in bar workers and significantly among the general population 1 year post ban while cigarette consumption dropped significantly among bar workers. Disparity in knowledge between smokers and non-smoker of risk associated with SHS exposure reduced. Lack of understanding of the risk of ear infections in children posed by SHS exposure was notable. Evidence for advanced de-normalisation of smoking behaviour and intensification of stigma because of the introduction of the legislation was dependent on many factors, quality of smoking facilities played a key role. Conclusions: Ireland’s smoke-free legislation was associated with a drop in prevalence and cigarette consumption. Disparity in knowledge between smokers and non-smokers of the risk posed by SHS exposure reduced however the risk of ear infections in children needs to be effectively disseminated. The proliferation of ‘good’ smoking areas may diminish the potential to reduce smoking behaviour and de-normalise smoking.
