[ES] La astrología grecorromana es un código lingüístico con signos (planetas, signos del Zodíaco), y con leyes de interconexión entre ellos (eclíptica, aspectos, casas, límites), y ha de ser valorada no sólo desde la perspectiva de su cientificidad, sino desde la de sus funciones para el individuo y la sociedad: es un conocimiento del futuro singular que afecta a la totalidad de lo implicado, y en la totalidad de sus dimensiones. Suple así el conocimiento de la ciencia antigua, que no fue capaz de incluir ni lo futuro ni lo singular. La astrología integra al individuo en la comunidad, integrándolo previamente en su universo semántico. Cosmos, mundo humano y mundo natural se armonizan totalmente.

Evidence of interpersonal violence has been documented previously in Pleistocene members of the genus Homo, but only very rarely has this been posited as the possible manner of death. Here we report the earliest evidence of lethal interpersonal violence in the hominin fossil record. Cranium 17 recovered from the Sima de los Huesos Middle Pleistocene site shows two clear perimortem depression fractures on the frontal bone, interpreted as being produced by two episodes of localized blunt force trauma. The type of injuries, their location, the strong similarity of the fractures in shape and size, and the different orientations and implied trajectories of the two fractures suggest they were produced with the same object in face-to-face interpersonal conflict. Given that either of the two traumatic events was likely lethal, the presence of multiple blows implies an intention to kill. This finding shows that the lethal interpersonal violence is an ancient human behavior and has important implications for the accumulation of bodies at the site, supporting an anthropic origin.

Esta dissertação é fruto de uma pesquisa realizada em uma enfermaria feminina de clínica médica de um hospital universitário público da cidade do Rio de Janeiro. Nesta pesquisa, busquei uma compreensão sobre as relações e articulações do trabalho médico e de enfermagem. Partindo da perspectiva hermenêutica, busquei estabelecer conversações com, e entre, sujeitos de pesquisa, grupos profissionais, o próprio estabelecimento hospitalar, a biomedicina - seus fatos e artefatos. Ademais, foram inspiradores para a desejada compreensão os science studies e seus exemplos de como acompanhar e interpretar especialistas em seus campos de prática. A pesquisa, especificamente, foi construída e desenvolvida com o uso de métodos qualitativos, como a observação etnográfica e entrevistas semiestruturadas, tendo a primeira servido de fundamentação para a segunda. O exercício interpretativo posto em curso desde a projeção da pesquisa não se esgotou com o seu término: teve continuidade e se fez presente na produção desta dissertação, ao modo de uma narrativa. Para sustentar a opção pela narrativa, assumo-a como um relato de risco, da maneira como sugere Latour para se descrever as redes e seus atores. Assim, pretendi incluir no texto a intensa movimentação e toda a sorte de eventos que se colocam como desafio às práticas destes profissionais, além de conferir agência aos sujeitos e às coisas. Dentro desta proposta, a narrativa traz um prólogo em que se posiciona entre os trabalhos do campo da Saúde Coletiva; em sua introdução, oferece um resumo ampliado de sua construção; no capítulo um, discorre sobre como o pesquisador negociou a existência da pesquisa com a instituição hospitalar, e trata também de um de seus fundamentos, a hermenêutica filosófica, em conversações com Rorty e Ayres. No segundo, traz um relato sobre a constituição coletiva de médicos e enfermeiros a partir de Fleck. Convida, ainda, um dos sujeitos da pesquisa a oferecer um conceito que ilumina as tensões das relações cotidianas entre enfermeiras e médicos; apresenta, a partir do conceito oferecido, alguns retratos destas relações. No terceiro, o caso de uma usuária que teve o prolongamento de sua vida decidida em uma reunião e um telefonema, é usado com o conceito de paradigma, em Kuhn, para dizer sobre as visões de mundo de médicos e enfermeiras. No quarto, tenta tornar dinâmica a constituição coletiva de médicos e enfermeiras ao relacioná-la às suas visões de mundo, aos processos de enculturação dos dois grupos profissionais; para isso recorre ao conceito de conhecimento tácito e às distintas categorias de expertise, como desenvolvidas por Collins e Evans. Diz sobre o que médicos e enfermeiras sabem do que estão falando/fazendo. Por fim, propõe duas possibilidades de desfecho para a dissertação: a primeira, que as práticas de médicos e enfermeiros são incomensuráveis entre si; a segunda, que médicos e enfermeiros dividem uma zona de troca forçada. Há ainda um encerramento. Nele, através da descrição de uma médica virtuosa, convida os leitores a uma conversa sobre os sujeitos contemporâneos e sobre o mundo em que vivemos.

Isolated in the middle of the Pacific Ocean, Hawaii was one of the last areas to be reached by "western" explorers; as a consequence, some ancient traditions were preserved in Hawaii well into the 19th and 20th centuries, providing an opportunity to learn from a surviving indigenous culture. An account is given of the division of the islands into various units and their exploitation. The smallest major divisions were the "ahupua'as," which spread out at the base along the shore and were self-sufficient units. In this way the ancient Hawaiians recognized the relationship between the land and sea, rainfall and vegetation, nutrients and runoff and preserved the integrity of the delicately balanced ecosystem of which they were a part and upon which they relied for their every need. Modern parallels to this ancient system are broken and irregular; the reorganization of the "ahupua'a" system marked the beginning of the decline of Hawaiian ecosystems. Although steps are being taken to remedy the present situation, Hawaii now ranks among the highest in the nation for its levels of pollution, endangered species and disappearing habitats. More and more, the model for improved management is being sought in the revival of ancient traditions.

Recent years have seen a dramatic increase in litigation against the National Marine Fisheries Service, NOAA. Litigation may affect personnel throughout the agency, including scientists, whose work is often directly or indirectly influenced by complex legal requirements, but who may not be in a position to comment or engage in public dialogue. It may be helpful for scientists and other agency personnel to join the ongoing discussion in the legal community regarding the interface of science and law. This paper provides a starting point with a selected introduction to relevant legal literature in this area. It uses the phrase “forensic fisheries science” to describe the application of science to legal requirements in the fishery management context. It concludes with suggestions for future research that could assist NMFS scientists as they grapple with the challenge of using science to help the agency meet its complex legal requirements. Forensic: belonging to, used in, or suitable to courts of judicature or to public discussion and debate; argumentative, rhetorical; relating to or dealing with the application of scientific knowledge to legal problems (Merriam-Webster Online Dictionary )

The Northeast Fisheries Science Center of NOAA's National Marine Fisheries Service has a long history of research on benthic invertebrates and habitats in support of the management of living marine resources. These studies began in the 1870's under Spencer F. Baird's guidance as part of an effort to characterize the Nation's fisheries and living marine resources and their ecological interactions. This century and a quarter of research has included many benthic invertebrate studies, including community characterizations, shellfish biology and culture, pathology, ecosystem energy budget modeling, habitat evaluations, assessments of human impacts, toxic chemical bioaccumulation in demersal food webs, habitat or endangered species management, benthic autecology, systematics (to define new species and species population boundaries), and other benthic studies. Here we review the scope of past and current studies as a background for strategic research planning and suggest areas for further research to support NOAA's goals of sustainable fisheries management, healthy coastal ecosystems, and protected species populations.
