Vulnerabilidade ao stress, depressão e agressividade nas forças policiais

Os agentes de Policia, são elementos expostos a vários fatores de Vulnerabilidade ao Stress, sendo este vivenciado de diferentes formas. Neste estudo procurou-se conhecer a relação entre a vulnerabilidade ao Stress, a Depressão e a Agressividade nas forças policiais. Participaram 350 indivíduos, 34 do sexo feminino e 316 do sexo maculino com uma média de idades de 25.80 (DP=5.28) e com uma média de serviço na PSP de 1.99 anos (DP=.46), selecionados por conveniência. Todos os participantes trabalham há um ano no serviço operacional. As medidas utilizadas no presente estudo foram a Depression Anxiety Stress Scale (D.A.S.S), criada por Lovibond e Lovibond em (1995), tendo sida traduzida e validada para portugês por Ribeiro e colaboradores (2004), a Escala de Vulnerabilidade ao Stress (23QVS) - foi desenvolvida por Vaz Serra, (2000), com o objectivo de auto-avaliar a vulnerabilidade ao stress em relação com a psicopatologia e o questionário de Agressividade (Aggression Questionnaire) foi criado por Buss e Perry (1992) , tendo sido traduzida e validada para a população portuguesa por Simões (1993). Os resultados obtidos no presente estudo indicam, em termos gerais e quanto maior é a vulnerabilidade ao stress maior é a agressividade e a sintomatologia depressiva.

The Convective Storm Initiation Project

The Convective Storm Initiation Project (CSIP) is an international project to understand precisely where, when, and how convective clouds form and develop into showers in the mainly maritime environment of southern England. A major aim of CSIP is to compare the results of the very high resolution Met Office weather forecasting model with detailed observations of the early stages of convective clouds and to use the newly gained understanding to improve the predictions of the model. A large array of ground-based instruments plus two instrumented aircraft, from the U.K. National Centre for Atmospheric Science (NCAS) and the German Institute for Meteorology and Climate Research (IMK), Karlsruhe, were deployed in southern England, over an area centered on the meteorological radars at Chilbolton, during the summers of 2004 and 2005. In addition to a variety of ground-based remote-sensing instruments, numerous rawin-sondes were released at one- to two-hourly intervals from six closely spaced sites. The Met Office weather radar network and Meteosat satellite imagery were used to provide context for the observations made by the instruments deployed during CSIP. This article presents an overview of the CSIP field campaign and examples from CSIP of the types of convective initiation phenomena that are typical in the United Kingdom. It shows the way in which certain kinds of observational data are able to reveal these phenomena and gives an explanation of how the analyses of data from the field campaign will be used in the development of an improved very high resolution NWP model for operational use.
