Correctional staff are instrumental in ensuring the success of any correctional institution; therefore, investigating how the work environment impacts correctional workers is essential. To determine the effects of supervisory consideration, supervisory structure, job variety, and perceptions of training on correctional staff job stress, job satisfaction, and organizational commitment, data from a survey of staff at a Midwestern private correctional facility were examined. The Ordinary Least Squares regression results indicate that each of the work environment factors had a significant impact on one or more of the three outcomes. Specifically, supervisory consideration and perceptions of training decreased job stress. Supervisory consideration, job variety, and perceptions of training had positive effects on job satisfaction. Finally, supervisory consideration, supervisory structure, job variety, and perceptions of training had positive relationships with organizational commitment. 相似文献

It is natural to suppose that a prosecutor's conviction rate—theratio of convictions to cases prosecuted—is a sign ofhis competence. Prosecutors, however, choose which cases toprosecute. If they prosecute only the strongest cases, theywill have high conviction rates. Any system that pays attentionto conviction rates, as opposed to the number of convictions,is liable to abuse. As a prosecutor's budget increases, he allocatesit between prosecuting more cases and putting more effort intoexisting cases. Either can be socially desirable, dependingon particular circumstances. We model the tradeoffs theoreticallyin two models, one of a benevolent social planner and one ofa prosecutor who values not just the number of convictions butthe conviction rate and unrelated personal goals. We apply themodel to U.S. data drawn from county-level crime statisticsand a survey of all state prosecutors by district. Convictionrates do have a small negative correlation with prosecutorialbudgets, but conditioning on other variables in regression analysis,higher budgets are associated both with more prosecutions andhigher conviction rates. 相似文献

Unaccompanied refugee children and adolescents are a vulnerable group: they live not only in a relatively difficult situation as minor refugees staying in another country, but also face other risks due to the absence of their parents, such as traumatic experiences, exploitation or abuse. The difficult living situation of these unaccompanied refugee children and adolescents might therefore threaten their emotional well-being, resulting in important emotional and behavioural problems. This 'psychological' perspective shows the necessity of a strongly elaborated reception and care system for these children and adolescents in order to meet their specific situation and needs. Nevertheless, the case study of unaccompanied refugee minors living in Belgium, as explored in this paper, shows that the legal perspective on these youths - considering them as 'refugees' and 'migrants', not as 'children' - is predominantly the starting point to build the care system on. Moreover, this legal perspective contrasts sharply with the psychological perspective, as such that these children and adolescents do not receive appropriate support and care as they need. 相似文献

A method that quickly and inexpensively differentiates crime scene samples from multiple donors would expedite casework analysis by allowing the selection of probative items requiring comprehensive testing. This new method need not be perfectly definitive nor give a complete 13 locus short tandem repeat (STR) profile; it simply must be able to differentiate between most victim and suspect samples. We describe the development of multiplex, single nucleotide polymorphism (SNP), fluorescence resonance energy transfer-based real-time polymerase chain reaction (PCR) assays to fulfill this need. Dual probes, one fluorescently labeled and the other labeled with a quencher, are monitored during a melt analysis to reveal an increase in fluorescence, which allows the assessment of the two SNP alleles. Two alternate 6-plex assays (with and without gender determination) have been developed for the six-color RG6000 real-time instrument (Corbett Robotics, Inc.) and one seven SNP plus gender assay (performed as two 4-plex assays, one with gender the other without) have been developed for use in four/five color real-time instruments. This technique can discriminate between 95% and 99% of samples from different individuals. This assay is fast (approximately 2 h), much less expensive than STR analysis, and uses a real-time PCR instrument which is found in most forensic and molecular biology labs. 相似文献

This article addresses a problem faced by many historians of living standards: what was the effect of unemployment on the real incomes of working-class families during industrialization? The 1901 Census of Canada offers a rare opportunity to answer this question, and to measure both unemployment and living standards while taking into account the contributions of all family wage-earners. The conclusion is that average weekly or monthly wages were more important than work duration in determining the living standards of poor families. 相似文献
