Estudo dos Sintomas Psicopatológicos nas Forças Policiais Portuguesas: estudo comparativo na GNR, PSP e PJ

O presente estudo exploratório visa analisar a possibilidade de existência de Sintomas Psicopatológicos nas Forças Policiais Portuguesas GNR, PSP e PJ. Por se verificar um aumento do suicídio, nestes profissionais, com uma taxa quatro vezes superior no ano de 2008. O objectivo é essencialmente o de prevenção, conhecendo as causas, poder-se-ia intervir em tempo próprio diminuindo a taxa de suicídio. Para atingir o objectivo enunciado vamos proceder à revisão da literatura e à descrição do estudo. Foram utilizados o questionário sócio-demográfico e o BSI (Brief Symptoms Inventory) na recolha dos dados de 45 polícias (15 GNR, 15 PSP e 15 PJ) que exercem funções na Zona Centro do País e que voluntariamente colaboraram. Uma vez recolhidos os dados, estes foram introduzidos e processados no SPSS (Statistical Package for the Social Sciences) versão 13.0. Os resultados obtidos permitiram concluir que não existem diferenças estatisticamente significativas nas diferentes Forças policiais, relativamente aos sintomas Psicopatológicos. / This present exploratory study pretends to analyze the existence of psicopatologic symptoms in the Portuguese Policies Forces, Republican National Guard, Public Security Police and Judicial Police. By the constatation of the increase of the suicidal tendence in this professionals, with a four time superior tax when compared with 2008. The essential objective is the prevention of suicide, well known their causes, we will can act in the own an favorable timing diminishing the tax of suicidal tentative. To obtain the pronounced objective, we will proceed to a reading revision over the behaviour characteristics as the subjects that commit suicide and the role of the police activities that have over the happenings. After, that we will describe the used metodology that involve a social demographic enquire and the BSI that (Brief Symptoms Inventory) over a sample of 45 police man (15 GNR, 15 PSP and 15 PJ) wich activities are situated in the center of Portugal that have been voluntary to this experience. Once data is collected, it was entered into a computerized database and processed in the statistical program SPSS (Statistical Package for the Social Sciences). The obtained results will allow to conclude if exist significant statistical differences in the various Policies Forces, related with the psicopatologic symptoms.

A Computer-Aided Decision Support System for Making Locational Decisions, 1990

This report is the product of a first-year research project in the University Transportation Centers Program. This project was carried out by an interdisciplinary research team at The University of Iowa's Public Policy Center. The project developed a computerized system to support decisions on locating facilities that serve rural areas while minimizing transportation costs. The system integrates transportation databases with algorithms that specify efficient locations and allocate demand efficiently to service regions; the results of these algorithms are used interactively by decision makers. The authors developed documentation for the system so that others could apply it to estimate the transportation and route requirements of alternative locations and identify locations that meet certain criteria with the least cost. The system was developed and tested on two transportation-related problems in Iowa, and this report uses these applications to illustrate how the system can be used.

A Systematic Review of Entrepreneurship Education Literature in Nigeria: Where is the Focus of Research?

Purpose- Entrepreneurship education (EEd) plays a crucial role in the development of entrepreneurs and the enhancement of entrepreneurial activities in every economy. This paper examined what Higher education Institutions (HEIs) do in learning and teaching of entrepreneurship in general and how entrepreneurship development takes place in Nigerian HEIs. The outcome from this study will enable a deeper understanding on what HEIs do EEd, with more exposure as to what the areas and focus of research is in the Nigerian context. Design/methodology/approach- The study adopted a systematic literature review approach- drawing from a computerized search of five selected data bases, using predetermined key words by the researchers. Findings: The main finding of this paper is that, related concepts like skills, intention, drive and attitude have been use in expounding discussions on the outcome of EEd, but very little has been written on entrepreneurial mind-set (EMS), of which other studies have suggested that it’s a crucial point in the journey of an entrepreneurs (Reed & Stoltz, 2011; Quality Assurance Agency for Higher Education (QAA), 2012; Neneh, 2012). Furthermore, learning and teaching of entrepreneurship in Nigerian HEIs seems to be more on creating awareness (about entrepreneurship) than actual preparation for entrepreneurship (For entrepreneurship). Research limitations/implications- The paper is limited since it is based on a review of literature from a selected databases- covering a specific time span. This potentially excludes other studies outside this time span. A more comprehensive overview of these contributions would benefit from employing tools such as Google Scholar, for an overview of the sub–domains online. Originality/value – There are limited studies that focus on the issue of entrepreneurial mind-set in entrepreneurship education in Africa, specifically Nigeria. This paper and its focus in particular, have laid down pioneering ground work for research on entrepreneurial mind-set development in Nigerian entrepreneurship education.

Computer-based tools for assessing micro-longitudinal patterns of cognitive function in older adults

Patterns of cognitive change over micro-longitudinal timescales (i.e., ranging from hours to days) are associated with a wide range of age-related health and functional outcomes. However, practical issues with conducting high-frequency assessments make investigations of micro-longitudinal cognition costly and burdensome to run. One way of addressing this is to develop cognitive assessments that can be performed by older adults, in their own homes, without a researcher being present. Here, we address the question of whether reliable and valid cognitive data can be collected over micro-longitudinal timescales using unsupervised cognitive tests.In study 1, 48 older adults completed two touchscreen cognitive tests, on three occasions, in controlled conditions, alongside a battery of standard tests of cognitive functions. In study 2, 40 older adults completed the same two computerized tasks on multiple occasions, over three separate week-long periods, in their own homes, without a researcher present. Here, the tasks were incorporated into a wider touchscreen system (Novel Assessment of Nutrition and Ageing (NANA)) developed to assess multiple domains of health and behavior. Standard tests of cognitive function were also administered prior to participants using the NANA system.Performance on the two “NANA” cognitive tasks showed convergent validity with, and similar levels of reliability to, the standard cognitive battery in both studies. Completion and accuracy rates were also very high. These results show that reliable and valid cognitive data can be collected from older adults using unsupervised computerized tests, thus affording new opportunities for the investigation of cognitive function.

Synchronous primary malignant tumors of the breast, caecum and sigma. Case report

We present the case of a patient with a double adenocarcinoma of the right colon and sigma associated with a bilateral infiltrating ductal breast carcinoma. Sigma and caecum bowel cancers were diagnosed at colonoscopy, with computerized tomography staging, while breast cancer was found with screening mammography. Following right hemicolectomy , sigmoidectomy and bilateral mastectomy the histology confirmed the presence of colonic adenocarcinoma and infiltrating and in situ lobular cancer. This case report reviews the treatment of synchronous neoplasia.
