Defining plausible migration rates based on historical tagging data: a Bayesian mark-recapture model applied to English sole (Parophrys vetulus)

A generalized Bayesian population dynamics model was developed for analysis of historical mark-recapture studies. The Bayesian approach builds upon existing maximum likelihood methods and is useful when substantial uncertainties exist in the data or little information is available about auxiliary parameters such as tag loss and reporting rates. Movement rates are obtained through Markov-chain Monte-Carlo (MCMC) simulation, which are suitable for use as input in subsequent stock assessment analysis. The mark-recapture model was applied to English sole (Parophrys vetulus) off the west coast of the United States and Canada and migration rates were estimated to be 2% per month to the north and 4% per month to the south. These posterior parameter distributions and the Bayesian framework for comparing hypotheses can guide fishery scientists in structuring the spatial and temporal complexity of future analyses of this kind. This approach could be easily generalized for application to other species and more data-rich fishery analyses.

Efficacy of a cognitive and behavioural psychotherapy applied by primary care psychologists in patients with mixed anxiety-depressive disorder: a research protocol

Background: In contrast with the recommendations of clinical practice guidelines, the most common treatment for anxiety and depressive disorders in primary care is pharmacological. The aim of this study is to assess the efficacy of a cognitive-behavioural psychological intervention, delivered by primary care psychologists in patients with mixed anxiety-depressive disorder compared to usual care. Methods/Design: This is an open-label, multicentre, randomized, and controlled study with two parallel groups. A random sample of 246 patients will be recruited with mild-to-moderate mixed anxiety-depressive disorder, from the target population on the lists of 41 primary care doctors. Patients will be randomly assigned to the intervention group, who will receive standardised cognitive-behavioural therapy delivered by psychologists together with usual care, or to a control group, who will receive usual care alone. The cognitive-behavioural therapy intervention is composed of eight individual 60-minute face-to face sessions conducted in eight consecutive weeks. A follow-up session will be conducted over the telephone, for reinforcement or referral as appropriate, 6 months after the intervention, as required. The primary outcome variable will be the change in scores on the Short Form-36 General Health Survey. We will also measure the change in the frequency and intensity of anxiety symptoms (State-Trait Anxiety Inventory) and depression (Beck Depression Inventory) at baseline, and 3, 6 and 12 months later. Additionally, we will collect information on the use of drugs and health care services. Discussion: The aim of this study is to assess the efficacy of a primary care-based cognitive-behavioural psychological intervention in patients with mixed anxiety-depressive disorder. The international scientific evidence has demonstrated the need for psychologists in primary care. However, given the differences between health policies and health services, it is important to test the effect of these psychological interventions in our geographical setting.

A imagem no espelho: o drama de uma ficção

Esta dissertação se propõe a estudar o tema do duplo a partir da produção fílmica de Hanns Heinz Ewers, O estudante de Praga, e o conto de Mário de Sá-Carneiro, A confissão de Lúcio, ambos de 1913. Asduas narrativas se organizam em torno de um triângulo amoroso e compartilham o mesmo destino trágico. Tomando como suporte, inicial, de leitura os textos de Freud e Rank, de 1914, Sobre o narcisismo: uma introdução e O duplo, respectivamente, o artigo de Lacan, O estádio do espelho como formador da função do eu (1949) e seu seminário sobre a angústia, pretende-se estabelecer um diálogo entre literatura e psicanálise, considerando a questão do desdobramento do eu e suas variantes, a cisão do eu em múltiplos eus e o desaparecimento da imagem. A imagem no espelho, a princípio fonte de júbilo, escamoteia um drama: o drama de um sujeito que se constitui a partir de uma ficção

Decision analysis applied to the fishery of the sea snail Concholepas concholepas from central northern coast of Chile

Formal decision analysis was applied to the management of loco (Concholepas concholepas, Fam. Muricidae) in Chile, 29-35 degrees S. Four interested groups were considered "Fishers", "Scientists", "Buyers" and the "State", along with three fishing effort levels and four subobjectives. The method was found to encourage the emergence of a consensus (here: halving of effort), and is recommended for use in other fisheries.

Video technology applied to the management of Bahrain's marine resources

Video technology has been used as a tool in research for many years. However, its widespread use as a fisheries management tool has been limited due to its relatively high cost. This is changing as video technology becomes a household commodity now widely available throughout the world.

Performance: o desenrolar do drama em um grupo de Capoeira Angola

Este trabalho é um estudo de caso cujo objeto consiste em um grupo de capoeira angola que passava por um momento de transição. A partir do rompimento entre os dois principais líderes do grupo sem mestre, investigou-se as tensões existentes reveladoras de diferentes pontos de vista sobre a capoeira e a atuação do mesmo em suas redes de relacionamento. Estas diferenças são significativas uma vez que estão relacionadas com as transformações em torno das concepções sobre esta atividade e também se inserem no contexto de transformações em curso na cidade do Rio de Janeiro. Concebendo-se a capoeira angola como um estilo de vida, as diversas maneiras de pensá-la também geram diferentes maneiras de atuar na sociedade. A metodologia consiste na pesquisa qualitativa com observação participante. Escolheu-se a abordagem pela performance por se acreditar que os valores são comunicados também por meio das diferenças de movimentação. Ao final da pesquisa, concluiu-se que o grupo investigado passava por um momento de transição, que considero como uma passagem apoiada nas considerações de Victor Turner, já em vias de transição para a fase seguinte a partir da indicação do treinel que ficou responsável de se juntar a um grupo já estabelecido.
