The Birnbaum-Saunders Distribution is based on an physical damage that produces the cumulative fatigue materials, This fatigue was identified as an important cause of failure in engineering structures. Recently, this model has been applied in other areas such as health sciences, environmental measures, forestry, demographic, financial, among others. Due to it s importance several distributions have been proposed to describe the behavior of fatigue resistance. However there is not an argument about which is more effective for the analysis of data from fatigue. A major problem to choose a statistical distribution, is that often several models fit the data well in the central, but, however, the extremes of distribution raise questions about the decision to select some of their models. The lack of data at the extremes distribution is justified to consider other arguments like the use of a specific statistical distribution, and thus reject other models. In this work we study some extensions of the distribution Birnbaum-Saunders with a mixture of normal scale, in which the procedure will for obtaining inferences will be considered from a Bayesian perspective based on the methods Monte Carlo Markov Chain (MCMC). to detect possible observations influential in the models considered, we used the Bayesian method of analysis influence in each case based on the Kullback-Leibler divergence. Moreover, the geometric Birnbaum-Saunders model is proposed , for data survival.
Processo de trabalho e produção do cuidado de enfermagem em uma instituição de apoio ao indígena
(Universidade Federal de São Carlos, 2012-01-09) Ribeiro, Aridiane Alves; Arantes, Cássia Irene Spinelli; https://lattes.cnpq.br/4246837549578145; https://lattes.cnpq.br/8256619308165279
This study aimed primarily to examine the workers conceptions about the process of nursing care in an institution of attention to indigenous health care. The starting point was the reference of the work process and its relation to the use of technologies in health care production. It was also considered the National Policy for the Health of Indigenous Peoples, particularly the distincted attention that should permeate the work process at the institution being studied. The empirical material was obtained from document analysis, systematic observations, guided by the flowchart Merhy Analyzer and by ten interviews with the nursing staff. A thematic analysis of categorical data was conducted and it revealed a fragmented labor process, focused on procedures and cast by institutional and bureaucratic rules. In the process of nursing work there is a clear gap from thinking to acting because planning the Schedule is a job for the responsable worker and the nursing station performs it. The worker s reports showed a sense of equality among human beings in the caring process. Therefore, it was also learned that in some situations, there is an establishment of asymetric relationship showing a certain denial of what is said. The assisted Indians in Support House are perceived by respondents as a retracted and suspicious individual. The care process should be based on a relationship based on trust. To approach the Amerindian, the nursing worker needs to undertake, especially light Technologies, empathy and affection. However, work in live action, hence the use of relational technologies, can be captured by the rigidity of the bureaucratic organizational structure. The act is cast and creative potential of workers is not valued. The caring process presents a special care, the monitoring, which is the activity of nursing staff to accompany the Indians to specialized health services outside the home support. Although the National Policy advocates a distincted attention, the work process in the institution being studied, seemed not to potentiate nor favors a care where it is considered the indigenous peculiarities of self-health care.
