Evaluación poblacional del recurso concha de abanico (Argopecten purpuratus) en el Callao. 20 al 23 y 26 de abril 1999

Describe los resultados de la evaluación poblacional de concha de abanico en el Callao del 20 al 23 y 26 de abril de 1999, cubriendo el área comprendida entre las islas San Lorenzo, El Frontón y la Punta con el objeto de estimar la magnitud poblacional y determinar las características del recurso en relación al ambiente marino, teniendo en cuenta que el recurso se encuentra entre los moluscos de mayor importancia económica en el Perú y es uno de los principales invertebrados sometidos a intensa extracción comercial.

A simple randomized algorithm for consistent sequential prediction of ergodic time series

We present a simple randomized procedure for the prediction of a binary sequence. The algorithm uses ideas from recent developments of the theory of the prediction of individual sequences. We show that if thesequence is a realization of a stationary and ergodic random process then the average number of mistakes converges, almost surely, to that of the optimum, given by the Bayes predictor.

Auditoria Interna nas Empresas Cabo-Verdianas

A globalização, a evolução e a competitividade dos mercados hoje em dia, faz com que as organizações sentem necessidade de informações úteis e atempadas que facilitem à gestão alcançar os seus objectivos e perspectivar o futuro. Portanto, a existência de auditoria interna nas organizações é importante, pois auxilia tanto os investidores fornecendo-lhes informações fidedignas, como os administradores ou gestores de topo, visto que o auditor actua em todas as áreas contabilísticas e não contabilísticas. O presente trabalho incide sobre a auditoria interna nas empresas cabo-verdianas. Para tal, realizaram-se pesquisas bibliográficas sobre auditoria e seus aspectos gerais, dando mais ênfase à auditoria interna. Conjuntamente, tendo como universo de pesquisa as empresas cabo-verdianas, foi elaborado um questionário aplicado a 70 empresas de diversos ramos de actividade, com a finalidade de comprovar a importância de auditoria interna para as empresas cabo-verdianas. Os resultados deste estudo indicam que, a maioria dos inquiridos da amostra afirmam que não possuem serviços de auditoria interna. No entanto, a maioria dos que o possuem são entidades de sucesso.

Usabilidade dos sites governamentais em Cabo Verde

Cabo Verde tem conhecido nos últimos anos, progressos notórios no que diz respeito ao desenvolvimento das Tecnologias de Informação e Comunicação, especialmente na área da governação electrónica e da democratização do acesso à Internet. Neste contexto, a usabilidade reveste-se de grande importância. O presente artigo analisa a usabilidade dos sites governamentais de Cabo Verde, identificando os problemas existentes e propondo medidas correctivas. Esta análise é feita recorrendo a uma amostra de 10 sites governamentais, utilizando o focusgroup e testes de usabilidade para cada um desses sites.

Taking "Galton's problem" Seriously : Towards a Theory of Policy Diffusion

This article builds on the recent policy diffusion literature and attempts to overcome one of its major problems, namely the lack of a coherent theoretical framework. The literature defines policy diffusion as a process where policy choices are interdependent, and identifies several diffusion mechanisms that specify the link between the policy choices of the various actors. As these mechanisms are grounded in different theories, theoretical accounts of diffusion currently have little internal coherence. In this article we put forward an expected-utility model of policy change that is able to subsume all the diffusion mechanisms. We argue that the expected utility of a policy depends on both its effectiveness and the payoffs it yields, and we show that the various diffusion mechanisms operate by altering these two parameters. Each mechanism affects one of the two parameters, and does so in distinct ways. To account for aggregate patterns of diffusion, we embed our model in a simple threshold model of diffusion. Given the high complexity of the process that results, strong analytical conclusions on aggregate patterns cannot be drawn without more extensive analysis which is beyond the scope of this article. However, preliminary considerations indicate that a wide range of diffusion processes may exist and that convergence is only one possible outcome.

Treatment and Early Intervention in Psychosis Program (TIPP-Lausanne): implementation of an early intervention programme for psychosis in Switzerland.

AIM: In a survey conducted in the Lausanne catchment area in 2000, we could estimate on the basis of file assessment that first-episode psychosis (FEP) patients had psychotic symptoms for more than 2 years before treatment and that 50% did not attend any outpatient appointment after discharge from hospital. In this paper, we describe the implementation of a specialized programme aimed at improving engagement and quality of treatment for early psychosis patients in the Lausanne catchment area in Switzerland. METHOD: The Treatment and Early Intervention in Psychosis Program-Lausanne is a comprehensive 3-year programme composed of (i) an outpatient clinic based on assertive case management; (ii) a specialized inpatient unit; and (iii) an intensive mobile team, connected for research to the Center for Psychiatric Neuroscience. RESULTS: Eight years after implementation, the programme has included 350 patients with a disengagement rate of 9% over 3 years of treatment. All patients have been assessed prospectively and 90 participated in neurobiological research. Based on this experience, the Health Department funded the implementation of similar programmes in other parts of the state, covering a total population of 540 000 people. CONCLUSION: Programmes for early intervention in psychosis have a major impact on patients' engagement into treatment. While development of mobile teams and assertive case management with specific training are crucial, they do not necessitate massive financial support to be started. Inclusion of a research component is important as well, in terms of service planning and improvement of both quality of care and impact of early intervention strategies.
