Turtle excluder devices (TEDs) are being trialed on a voluntary basis in many Australian prawn (shrimp) trawl fisheries to reduce sea turtle captures. Analysis of TED introductions into shrimp trawl fisheries of the United States provided major insights into why conflicts occurred between shrimpers, conservationists, and government agencies. A conflict over the introduction and subsequent regulation of TEDs occurred because the problem and the solution were perceived differently by the various stakeholders. Attempts to negotiate and mediate the conflict broke down, resulting in litigation against the U.S. government by conservationists and shrimpers. Litigation was not an efficient resolution to the sea turtle-TED-trawl conflict but it appears that litigation was the only remaining path of resolution once the issue became polarized. We review two major Australian trawl fisheries to identify any significant differences in circumstances that may affect TED acceptance. Australian trawl fisheries are structured differently and good communication occurs between industry and researchers. TEDs are being introduced as mature technology. Furthermore, bycatch issues are of increasing concern to all stakeholders. These factors, combined with insights derived from previous conflicts concerning TEDs in the United Stares, increase the possibilities that TEDs will be introduced to Australian fishers with better acceptance.

Omega-3 polyunsaturated fatty acids (omega-3 PUFAs) have been widely associated to beneficial effects over different neuropathologies, but only a few studies associate them to Parkinson`s disease (PD). Rats were submitted to chronic supplementation (21-90 days of life) with fish oil, rich in omega-3 PUFAs, and were uni- or bilaterally lesioned with 4 mu g of the neurotoxin 6-hydroxydopamine (6-OHDA) in the medial forebrain bundle Although lipid incorporation was evidenced in neuronal membranes, it was not sufficient to compensate motor deficits induced by 6-OHDA. In contrast, omega-3 PUFAs were capable of reducing rotational behavior induced by apomorphine, suggesting neuroprotection over dyskinesia The beneficial effects of omega-3 PUFAs were also evident in the maintenance of thiobarbituric acid reactive substances index from animals lesioned with 6-OHDA similar to levels from SHAM and intact animals. Although omega-3 PUFAs did not modify the tyrosine hydroxylase immunoreactivity in the substantia nigra pars compacta and in the ventral tegmental area, nor the depletion of dopamine (DA) and its metabolites in the striatum, DA turnover was increased after omega-3 PUFAs chronic supplementation Therefore, it is proposed that omega-3 PUFAs action characterizes the adaptation of remaining neurons activity. altering striatal DA turnover without modifying the estimated neuronal population.

O artigo investiga as contribui????es da pol??tica de governo eletr??nico para a reforma administrativa e a governan??a no Brasil. A pesquisa baseou-se na opini??o de informantes-chave dos quatro setores que atuam no e-gov: setor p??blico, iniciativa privada, terceiro setor e academia. Concluiu-se que as tecnologias de informa????o e comunica????o (TIC) podem ser a principal ferramenta para as iniciativas de moderniza????o do Estado, sendo ressalvado que o e-governo n??o pode ser visto como panac??ia para as reformas: o uso de tecnologias deveria caminhar em paralelo com outras medidas governamentais, nos campos pol??tico e econ??mico, por exemplo. Embora tenha sido reconhecido o potencial das TIC, o governo eletr??nico ainda n??o se encontra inserido com a ??nfase necess??ria na agenda governamental brasileira, de modo a contribuir decisivamente para a reforma administrativa e a governan??a.

O objetivo deste artigo ?? ampliar o conhecimento atual sobre os processos de aprendizado na implementa????o de pol??ticas p??blicas, procurando entender, em especial, os aspectos pol??ticos envolvidos nesses processos e como eles influenciam a evolu????o e os resultados dessas pol??ticas. Nesse sentido, com base em estudos de casos realizados sobre as pol??ticas industriais implementadas pelos estados da Bahia, do Cear?? e de Pernambuco nas ??ltimas d??cadas, conclui-se que o aprendizado de indiv??duos e grupos isoladamente dentro dos governos n??o parece garantir um efetivo aprendizado do governo na implementa????o de suas pol??ticas. Nos casos estudados, o aprendizado organizacional mostra-se como um processo no qual aspectos pol??ticos e cognitivos interagem sob as restri????es de arranjos institucionais espec??ficos. Esses aspectos pol??ticos tanto podem filtrar, retardar e at?? mesmo impedir a assimila????o organizacional do aprendizado de indiv??duos ou de grupos, como, outras vezes, podem aceler??-lo.

The impact of shift and night work on health shows a high inter- and intra-individual variability, both in terms of kind of troubles and temporal occurrence, related to various intervening factors dealing with individual characteristics, lifestyles, work demands, company organisation, family relations and social conditions. The way we define "health" and "well-being" can significantly influence appraisals, outcomes and interventions. As the goal is the optimisation of shiftworkers' health, it is necessary to go beyond the health protection and to act for health promotion. In this perspective, not only people related to medical sciences, but many other actors (ergonomists, psychologists, sociologists, educators, legislators), as well as shiftworkers themselves. Many models have been proposed aimed at describing the intervening variables mediating and/or moderating the effects; they try to define the interactions and the pathways connecting risk factors and outcomes through several human dimensions, which refer to physiology, psychology, pathology, sociology, ergonomics, economics, politics, and ethics. So, different criteria can be used to evaluate shiftworkers' health and well-being, starting from biological rhythms and ending in severe health disorders, passing through psychological strain, job dissatisfaction, family perturbation and social dis-adaptation, both in the short- and long-term. Consequently, it appears rather arbitrary to focus the problem of shiftworkers' health and tolerance only on specific aspects (e.g. individual characteristics), but a systemic approach appears more appropriate, able to match as many variables as possible, and aimed at defining which factors are the most relevant for those specific work and social conditions. This can support a more effective and profitable (for individuals, companies, and society) adoption of preventive and compensative measures, that must refer more to "countervalues" rather than to "counterweights".

This article studies the intercultural trajectory of a Portuguese female aristocrat of the eighteenth to nineteenth centuries. Her trajectory of intercultural transition from a Portuguese provincial lady into an independent owner of a sugar mill in tropical Bahia is documented through family letters, which provide a polyphonic representation of a movement of personal, family, and social transculturation over almost two decades. Maria Bárbara began her journey between cultures as a simple spectator-reader, progressively becoming a commentator-actor-protagonist-author in society, in politics, and in history. These letters function as a translation that is sometimes consecutive, other times simultaneous, of the events lived and witnessed. This concept of intercultural translation is based on the theories of Boaventura de Sousa Santos (2006, 2008), who argues that cultural differences imply that any comparison has to be made using procedures of proportion and correspondence which, taken as a whole, constitute the work of translation itself. These procedures construct approximations of the known to the unknown, of the strange to the familiar, of the ‘other’ to the ‘self’, categories which are always unstable. Likewise, this essay explores the unstable contexts of its object of study, with the purpose of understanding different rationalities and worldviews.

Através da comparação das ideias de três grandes teóricos da política no conturbado contexto da República de Weimar, esta dissertação pretende reconsiderar a crise da legitimidade política na modernidade tardia. Tal crise é concebida tanto em sentido estrito, enquanto crise das democracias liberais perante os efeitos de rápidas mudanças sociais e a emergência da política de massas, como em sentido lato, ou seja, enquanto crise dos alicerces político-intelectuais da era moderna. Nessa medida, veremos como os juízos de Weber, Kelsen e Schmitt não se limitam a veicular veredictos contrastantes sobre a democracia de massas, o parlamentarismo e os partidos políticos, remetendo também para narrativas distintas sobre o destino do homem moderno – narrativas que oscilam entre o optimismo moderado, a ambivalência e a reacção hostil.

This paper draws upon a detailed longitudinal survey of households living on agricultural plots in the northern three provinces of the Ecuadorian Amazon, the principal region of colonization by migrants in Ecuador since the 1970s. Following the discovery of petroleum in 1967 near what has subsequently come to be the provincial capital and largest Amazonian city of Lago Agrio, oil companies built roads to lay pipelines to extract and pump oil across the Andes for export. As a result, for the past 30 years over half of both Ecuador's export earnings and government revenues have come from petroleum extracted from this region. But the roads also facilitated massive spontaneous in-migration of families from origin areas in the Ecuadorian Sierra, characterized by minifundia and rural poverty. This paper is about those migrants and their effects on the Amazonian landscape. We discuss the data collection methodology and summarize key results on settler characteristics and changes in population, land use, land ownership, technology, labor allocation, and living conditions, as well as the relationships between changes in population and changes in land use over time. The population in the study region has been growing rapidly due to both natural population growth (high fertility) and in-migration. This has led to a dramatic process of subdivision and fragmentation of plots in the 1990's, which contrasts with the consolidation of plots that has occurred in most of the mature frontier areas of the Brazilian Amazon. This fragmentation has led to important changes in land tenure and land use, deforestation, cattle raising, labor allocation, and settler welfare.

El presente proyecto se propone como parte inicial de una investigación sobre la relación entre naturaleza/cultura/técnica. Tradicionalmente la naturaleza y la cultura se han considerado como ámbitos diferenciados y opuestos. Y es en esta distinción donde la técnica adquiere un lugar central. El pensamiento occidental sobre la técnica ha recibido diversas interpretaciones: desde una subordinación con respecto al conocimiento verdadero (episteme) en la filosofía clásica, un optimismo sobre la técnica como posibilidad de dominación de la naturaleza en el Renacimiento y la Ilustración, y la ambigüedad y desasosiego romántico (Mitcham, 1979). Durante el siglo XX se distinguen dos posiciones antagónicas sobre la técnica. Por un lado, una actitud “crítica” donde pueden identificarse los trabajos de filósofs de diferentes tradiciones como Ortega y Gasset (1939), Heidegger (1954), Mumford (1971) Ellul (1960) y la Escuela de Frankfurt. Por otro lado, una filosofía de la técnica “ingenieril” que consiste en el análisis de la tecnología como un paradigma de pensamiento y acción humana. Esta dicotomía ha sido interpretada por Eco como “apocalípticos e integrados”. Más allá de las mencionadas diferencias, lo que tienen en común ambas posiciones es que parten de una dicotomía entre cultura y naturaleza. Nuestra perspectiva rechaza esta dicotomía, por el contrario, evidenciamos una creciente imbricación entre ambas donde las fronteras entre una y otra se hacen difusas. La noción de “objeto técnico” propuesta por Simondon (2007) hace referencia a la inserción del objeto técnico en la cultura, donde debe reconocerse la “realidad humana” presente en el mismo. Ahora bien, esto no significa “humanizar el objeto técnico”, sino más bien indagar sobre el lugar que este ocupa en la cultura como también establecer su relación con la naturaleza. En el siglo XVII el hombre mismo es reinterpretado como máquina (La Mettrie, 2000). En la actualidad pueden identificarse dos tendencias en la concepción de la técnica: los «humanos-máquinas» y las «máquinas-humanas», en otras palabras, la disposición del humano hacia la máquina y la tendencia de la máquina hacia lo humano. No obstante, ambas posiciones siguen manteniendo una distinción taxonómica entre el cuerpo –o lo orgánico- y lo maquínico, lo que implica una consideración de esta relación de manera extrínseca. Frente a esta tensión Haraway propone el concepto de cyborg: «un organismo cibernético» (1995). Los desarrollos tecnológicos han producido una modificación tal en la vida de los seres orgánicos en los cuales ya no puede concebirse su cuerpo independientemente de la tecnología. Esto conduce a replantear la distinción entre “animales/hombres/máquinas”, entendiendo a los mismos como expresiones de naturaleza, cultura y tecnología respectivamente. Nuestra investigación parte de la hipótesis que la técnica diluye diferencias de orden natural y cultural a través de los objetos técnicos que son productos culturales. La estética se ocupa de la percepción sensible del mundo no puede eludir su dimensión técnica. Al margen de la crítica a la “Industria cultural” consideramos relevante la aproximación de Benjamin al problema de la técnica porque aborda la imbricación antes mencionada en el campo de la percepción. Según Benjamin la irrupción de la técnica al mismo tiempo que posibilita una estetización de la política que confluye en el fascismo como punto extremo también abre la posibilidad de desmontar la ideología del progreso infinito (1967). Una integración entre aproximaciones estéticas y políticas a la técnica Flusser (1983) propone la “caja negra” como metáfora de la técnica contemporánea. Su propuesta es la “apertura de la caja negra” que consiste en tomar conocimiento del funcionamiento del dispositivo. Nuestra propuesta de investigación aborda la técnica desde una consideración filosófica/estética/política, donde redefiniremos la técnica partiendo de la imbricación entre cultura y naturaleza. This project will set the basis for a sustained research on the relation nature/culture/technique. They have been traditionally considered as separate and even opposite fields. And it is on the brink of this distinction where technique plays a central role. In Western thought technique has received many interpretations since the beginnings of philosophy: from a subordination to true knowledge (episteme) in classic philosophy, or the optimism which sees in technique the possibility of dominating nature in the Renaissance and in the Enlightenment, to the Romantic ambiguity and uneasiness towards technological change (Mitcham, 1979). During the twentieth century two opposed approach on technique prevail. On one hand, a “critical” attitude such defines the work of philosophers of different traditions such as Ortega y Gasset (1939), Heidegger (1954), Mumford (1971) Ellul (1960) and the Frankfurt School. On the other hand there is an “engineering” philosophy of technique that consists in the analisis of technology as a paradigm to understand human action and thought. Besides their differences, both positions have in common a dichotomy between nature and culture. We reject such dichotomy. On the contrary we consider there is a growing intertwinement between both which blurs the borders of the concepts. Simondon’s notion of “technical object” refers to the insertion of the technique in culture where the “human reality” in it must be recognised. This does not imply “humanising the technical object”, but investigate on the role it plays on culture and establishing its relation to nature. To articulate this relation we will work with unorthodox approaches on technique such as Benjamin (1967), Flusser (1983) and others. The hypothesis of our project is that the traditional distinction of “animal/man/machine” must be re-thought, therefore raising the question on the blurring line between nature, culture and technique and its effects in philosophy, politics and aesthetics.
