The aim of the study was to ascertain suicide seasonality in the Greek population and to associate this seasonal variation with age, sex, and suicide method. Studying seasonality can be of help in establishing a public health policy, related with suicide prevention. This is an epidemiologic study based on forensic evidence. We studied the deaths caused by self‐injury (trauma), namely deaths by violent suicide (not self‐poisoning). Statistically significant suicide seasonality was established with a peak in May. This seasonal variation is attributed mainly to males. As for the method, suicide by hanging peaks in June and by shooting in April. It was also observed that seasonality for individuals above the age of 45 peaks in early May.  相似文献

Abstract

In technoscientific conditions what counts as knowledge creation is not primarily the individual experimental achievement that gives coherence to scientific practice and separates science from its publics; rather, it is a form of dispersed experimentation in more than human worlds: distributed invention power. Distributed invention power is organised and regulated through the pervasive securitisation of technoscience: surveillance and control of technoscientific fields as well as financialisation of its activities and research outputs. The securitisation of science reorders the traditional split between the public sphere, the private sector and the commons. The folding of each one of these spheres into the other underlies a constant, often antagonistic, oscillation between big science and open science. What is constitutive of the diverse movements that sustain open technoscience is not that they challenge technoscience as such but that they experiment with technoscience to create alternative forms of life.  相似文献

In Genograms in counselling practice: a review (part 1), recent literature on the use of genograms was reviewed and the efficacy and utility of genograms in counselling practice was examined. This paper outlines how a family genogram is constructed in a counselling setting. An approach to introducing the relevance of a genogram to the client is described as is the method of gathering and using information. The therapeutic use of genograms is also discussed.  相似文献

The purpose was twofold: (1) to assess whether laboratory tests can distinguish talented groups and less talented groups of children identified by their total scores in a battery of field tests and (2) to evaluate whether scores in field and laboratory tests are correlated. 36 children (ages 9 to 10 years) were divided into groups of higher and lower total scores on standing long jump, medicine ball throw, and sprint. Both groups were tested for maximum isometric force, force produced at the initial 100 msec., reactive force index, drop jump height, squat jump height, and maximum pedaling rate. Analysis showed the talented group had significantly (p < or = .05) higher scores on maximum isometric force, force produced in the initial 100 msec., and drop jump height than less talented children. Moderate to high correlations were found among scores for field performance tests with maximum pedaling rate. In conclusion, the laboratory tests distinguished the talented and less talented children in maximal isometric force, the force produced at the initial 100 msec., the reactive force index, and the drop jump height.  相似文献

A lack of information about disease in children can lead to erroneous views such as children believing that hospital admittance or the presence of a disease is a punishment for a perceived wrong. There has thus far been no standard tool available to measure children's illness conceptualizations from a Leventhalian framework. Three groups of children with eczema, asthma and eczema and asthma between the ages of 7 and 12 years of age were recruited. Children were given the Children's Illness Perception Questionnaire (CIPQ), a 26-item instrument adapted from the Illness Perception Questionnaire for adults. A Kuder - Richardson 20 test of reliability for dichotomous data was performed allowing an estimate of the internal consistency of the measurement scales. It can be seen that, for all three illness groups, internal consistency is acceptable for the timeline and consequences scale. The cure/control scale, however, was not internally consistent for any illness group. As health professionals, we need to develop the means to further understand how paediatric illness beliefs relate to specific disease types, age and psychosocial factors and the utility of this instrument is discussed within this context.  相似文献

Most cross‐cultural studies on country of origin or product‐country image (PCI) effects have implicitly assumed that national markets are composed of homogeneous consumers. Although many investigations in this field are described as cross‐cultural, most are in fact cross‐national. The overarching hypothesis of the present research is that PCI effects may vary across subcultures within a country. The results indicate that subcultural differences exist in the evaluation of culturally affiliated countries and their products. Cognitive responses converged to show that consumers' perceived linkages significantly influence the weight given to the country of origin in product evaluations. Several implications for managers and academic researchers are discussed. Copyright © 2003 Henry Stewart Publications.  相似文献

本文提出了一种新的并行演化算法――异步异构分层并行演化算法(AHHPGA),用于求解串并系统可靠性分配的多目标优化问题(RAP)。AHHPGA采用分层结构,上层由粗粒度模型构成,下层由细粒度模型构成。在AHHPGA的每个子种群中,采用不同的全局/局部搜索度和拓扑结构,构成异构模型。AHHPGA的迁移方式包括异步接收和异步迁出。采用基于模型的复杂系统可靠性评价工具(HiP-HOPS),以克服可靠性框图方法(RBD)的缺点。仿真结果表明,基于异步异构分层并行演化算法和HiP-HOPS工具的串并系统可靠性分配的多目标优化方法,优于传统的基于遗传算法的优化方法。  相似文献
