Suicide and suicidal risk in a rural context : social and psychological factors

Pollock, Leslie Ronald January 2000 (has links)
In a series of studies, rural and urban suicides were compared and the psychological factors underlying suicidal behaviour investigated. In the first study suicides in a Nfid-Wales county were examined and contrasted with a group of urban suicides. The pattern of rural suicides was found to differ from the urban suicides. Rural suicides were more evenly spread through the age bands, mostly married and used more violent means of death. Farmers comprised a large proportion of rural suicides and seem to differ from rural suicides in general in that 88% were over 45 years of age, most died of hanging, only 13% left notes and they had no record of previous suicide attempts. The factors that might cause farmers stress were examined. This showed that farmers found form filling and adjusting to government policy most stressful. Isolation was relatively unimportant as a stressor. In the third study the role of mood and problem solving in suicidal behaviour was investigated in three matched groups (suicidal, psychiatric control and non-psychiatric control). The suicidal group was found to display a careless and impulsive problem solving style and unique deficits in decision making and generation of alternative solutions. They were also more depressed, angry and confused. The problem solving deficits remained even when the effects of the mood differences were removed. The last study investigated the relationship between autobiographical memory and problem solving and found the suicidal group to be significantly more overgeneral in their memories, they produced fewer means and less effective problem solving solutions and these deficits were found to persist over time. These results were interpreted as support for these factors being trait features or alternatively requiring more time to recover. The findings were incorporated into a revised version of the "Cry of Pain" model of suicidal behaviour (Williams, 1997).

Geoestatística aplicada ao inventário florestal. / Geostatistic application to forestry inventory.

José Marcio de Mello 07 October 2004 (has links)
Este trabalho teve como objetivo geral avaliar o uso da geoestatística aplicada ao inventário florestal. Especificamente avaliaram-se: a estrutura de continuidade espacial de quatro características dendrométricas, os métodos de ajuste e seleção de modelos da função de semivariância, o comportamento dos intervalos de confiança clássico e geoestatístico e o potencial da krigagem de bloco para a predição volumétrica por talhão. Os dados para realização do presente estudo foram obtidos num povoamento de 987 hectares de Eucalyptus grandis, com sete anos de idade, localizados no município de Itapetininga, São Paulo, pertencente à Votorantin Celulose e Papel (VCP). Pelos semivariogramas anisotrópico e isotrópico avaliou-se a estrutura de continuidade espacial das características: volume, diâmetro médio quadrático, área basal e altura média dominante. Dois modelos da função de semivariância foram ajustados para o volume, por meio de quatro métodos de ajuste e a seleção do melhor modelo foi efetuada a partir do critério de Akaike (AIC) e por meio das técnicas de validação cruzada e preditiva. Quanto às simulações estocásticas com o modelo geoestatístico, verificou-se o desempenho da cobertura do intervalo de confiança clássico e geoestatístico em relação à cobertura nominal. A predição volumétrica por talhão foi obtida da krigagem com simulação em cada um dos talhões do povoamento. Verificouse que as características dendrométricas mensuradas no inventário florestal apresentaram-se estruturadas espacialmente. Este resultado sugeriu que no processamento do inventário florestal deve-se considerar a componente espacial, ou seja, as parcelas não devem ser tratadas de forma independente. Sugere-se o uso conjugado do critério de Akaike e da validação cruzada para seleção de modelos da função de semivariância. Detectou-se que os intervalos de confiança clássico e geoestatístico apresentaram cobertura inferior à cobertura nominal, para uma população espacialmente contínua. Porém, a cobertura do intervalo de confiança do estimador clássico foi bem inferior à cobertura nominal, mostrando viés substancial na estimativa da variância da média quando há estrutura de continuidade espacial. Para populações fixas o estimador clássico proporcionou cobertura observada igual à cobertura nominal. Este resultado comprova a validade da aleatorização para uso do Teorema Central do Limite, na definição do intervalo de confiança, independente da estrutura de continuidade espacial. Na presença de continuidade espacial, o uso do estimador geoestatístico (krigagem de bloco), para estimativa do volume por talhão, é preferido por duas razões: proporciona estimativa da precisão sem viés e é de baixo custo quando comparado ao estimador clássico. / This research evaluated the use of applied geostatistic forestry inventory. Specifically, it evaluated: the continuity of spatial structure of four dendrometric characteristics, the adjustment methods and model selection of the semi variance function, the behavior of classic and geostatístic confidence intervals and the potential of the block krigage for the stand volumetric prediction. Data were obtained in a 987 ha of Eucalyptus grandis forest plantation aged 7 years, located in Itapetininga county- São Paulo State, belonging to Votorantim Pulp and Paper (VCP). The spatial continuity structure of volume, quadratic average diameter, basal area and dominant average height was evaluated through the anisotropic and isotropic semi variogrammes. Two semi variance function models were adjusted for volume, through four adjustment methods. The selection of the best model was made starting from the Akaike information criterion (AIC) and through the crossed validation and prediction techniques. Departing from stochastic simulations, using geostatistic model the performa nce of the classic and geoestatístic confidence interval covering was verified, in relation to the nominal covering. The stands volumetric prediction was obtained from the krigage with simulation in each plantation stand. It was verified that the dendrométric characteristics measured in the forestry inventory presented spatially structured. This result suggested that, in the forestry inventory processing, spatial component should be considered, i.e., the plots should not be treated separately. It seems tha t the AIC and the cross validation for semi variance function model selection must be associated. It was detected that both classic and geostatistic confidence intervals presented lower covering than that of the nominal covering, for a spatial continuous population. However, the confidence covering interval of the classic estimator was much lower than the nominal covering, showing substantial bias in the estimate of the average variance, when there is structure of spatial continuity. For fixed populations, the classic estimator provided observed covering equal to the nominal covering. Thus, proving that the validity of the randomization for use of the Central Limit Theorem, in the definition of the confidence interval, independently of the structure of space continuity. The use of the geoestatístic estimator (block krigage) for estimating stand volume, in the presence of spatial continuity, is preferred because it provides unbiased and precise estimate at lower cost as compared to the classic estimator.

Herpetofauna do mosaico de unidades de conservação do Jacupiranga (SP) / Herpetofauna from the Conservation Units Mosaic of Jacupiranga (SP)

Eleonora Aguiar de Domenico 03 July 2008 (has links)
Tendo em vista a progressiva degradação e perda de habitats naturais, que resultam em declínios populacionais e extinções locais de espécies, torna-se imprescindível e urgente a realização de trabalhos de levantamento faunístico. Inventários são essenciais para melhorar a nossa compreensão da biogeografia da herpetofauna brasileira e para delinear estratégias de conservação efetivas que garantam a preservação do potencial evolutivo das espécies existentes. O nível de conhecimento acerca da biologia e da diversidade de anfíbios e répteis no Brasil, e particularmente no estado de São Paulo, ainda não é satisfatório e uma parcela significativa do que restou de seus ecossistemas foi pouco estudada. Este estudo visou determinar a composição de espécies das comunidades de serpentes, lagartos e anuros do Mosaico de Unidades de Conservação do Jacupiranga (SP) com base em dados coletados em duas localidades e em registros de museus. Foi obtida uma lista com 39 espécies de anuros, uma anfisbena, nove lagartos e 39 serpentes, que provavelmente compõem a herpetofauna do Mosaico. As espécies de anuros capturadas em armadilhas de interceptação e queda e por procura visual foram utilizadas para analisar a eficiência da amostragem. As análises indicaram que, provavelmente, em ambas as localidades e com os dois métodos utilizados, todas as espécies que compõem a comunidade local foram registradas. Com os dados de anuros coletados em armadilhas foram realizadas ainda análises comparando os diferentes ambientes amostrados. Os testes revelaram que há diferenças significativas entre ambientes antropizados e marginais com relação aos ambientes situados em mata melhor preservada. O pequeno número de espécies de répteis amostrados não permitiu que fossem feitas as mesmas análises realizadas para os anuros. A baixa abundância desses animais na natureza e as limitações dos métodos de captura utilizados impossibilitaram a realização de análises de desempenho da amostragem, de estimativas de riqueza e de uso de ambiente. A composição de espécies de anuros, lagartos e serpentes do Mosaico foi comparada com outras localidades a partir de dados disponíveis na literatura e as análises revelaram que, para todos os grupos, as espécies do Mosaico estão mais relacionadas com as comunidades ocorrentes na Floresta Ombrófilo Densa da encosta brasileira, em especial, com aquelas conhecidas para o contínuo de remanescentes florestais do estado de São Paulo que se inicia na Serra do Mar e termina na região do Vale do Ribeira. As informações de história natural, padrões de distribuição, composição de espécies e de seu estado de conservação geradas por esse trabalho podem ser utilizadas como base para o manejo da fauna estudada e para o estabelecimento de medidas conservacionistas pautadas em dados concretos. / Field surveys are urgently in need due to the continuing loss of natural habitats and resulting populational decline and local species extinction. Herpetofaunal surveys are essential to improve our understanding of biogeographical issues concerning this group, and to delineate effective conservation strategies to preserve the evolutionary potential of existing lineages. The knowledge of amphibian and reptile biology and diversity in Brazil, and particulary in the state of São Paulo, is still unsatisfactory. Additionally, a significative portion of the remaining natural areas of this state have been poorly studied. This study aims to determine species composition of anuran, lizard and snake communities from the biological reserve known as Mosaico de Unidades de Conservação do Jacupiranga (SP), and it is based on data collected in two localities as well as on records of museum specimens. As a result, a list with 39 anurans, 1 amphisbaenian, 9 lizards and 39 snakes was produced for the Mosaico. The specimens of anurans recorded during the study were used to analyze sampling effectiveness. This analysis indicated a high probability that all species composing the local community were actually registered. The data of anurans collected in pitfall traps were also used to compare the different environments sampled. The tests showed significant differences among secondary environments, modified by human activities, and mature forests. The same tests could not be done with reptiles due to the small samples captured in pitfall traps. The anuran, lizard and snake assemblages of the Mosaico were compared with other localities assemblages based on data from the literature. Analyses show that the herpetological fauna of the Mosaico resembles more closely to communites present in coastal Atlantic Rainforest, particulary to fauna of the remnants of this ecossistem located between Serra do Mar and Vale do Ribeira in the state of São Paulo. Information on natural history, distribution patterns, species composition and conservation status provided in the present work can be used for faunal management and lead to efficient species conservation planning.
