In this article, we explored the effect of prior victimization severity on perceived risk using a cross-national sample. We extracted data for all variables from the International Criminal Victimization Survey (ICVS) and the European Survey on Crime Safety (EU ICS). Using Ordinary Least Squares (OLS) regression for both pooled data and individual countries, we found that, in addition to numerous control and prior victimization variables, our key independent variable—perceived severity of victimization—generally influences levels of perceived risk. Discussion of the results and limitations of the study are also included. 相似文献

In Rossettiren obsesioa (Rossetti's Obsession), a short and explicitly meta-literary novel published in 2000, Ramon Saizarbitoria presents a Basque writer wrestling a formidable lover: the Spanish readership. The question that Eugenia, the woman from Madrid, constantly asks the writer, “¿Qué os pasa a los vascos?” (“What's wrong with you Basques?”), encapsulates the ambiguity of the relationship which unites these two indisputably allegorical characters. The difficult interaction between the powerful Spanish literary field and the emerging Basque literary field, doomed to coexist and moved by reciprocal feelings of fascination and irritation, becomes the novel's subject matter. Is translation – and its corollary, an access to a larger literary market – a pure and neutral instrument of liberation for the writer who expresses himself in a minority language, or could it become, in certain circumstances, a threat to his autonomy? 相似文献

Field studies in forensic entomology seem to assume that a cadaver is a resource equally accessible to flies, irrespective of the species’ size, behavior, and sensorial capacity. We aimed to challenge this assumption by experimentally manipulating baited traps in order to test whether the accessibility to decomposing baits is related to the following: (i) the diversity of necrophagous dipterans; (ii) the body size of adults; and (iii) the female sexual maturity stage. The experiment was performed in a rainforest fragment in Northeastern Brazil, in an area characterized by high levels of homicides. Traps baited with decomposing chicken liver had three levels of access: easy (six openings on the trap), intermediate (three), and difficult (one). A total of 750 adults of Calliphoridae, Fanniidae, Muscidae, Phoridae, and Sarcophagidae were collected. Of the 18 species recorded, Megaselia scalaris was the most abundant (46.8%) followed by Lucilia eximia (29.7%) and Chrysomya megacephala (9.8%). The number of species increased significantly with the accessibility level, but overall abundance did not differ, as a consequence of the numerical dominance of M. scalaris. A strong female bias (>91%) was observed in all traps. For Calliphoridae specimens, 90% of the females caught in traps under intermediate and difficult access were sexually mature. By empirically demonstrating that limitation of access and exclusion of visual stimuli do not deter several dipteran species from reaching a substrate, we expand the knowledge on the factors that can shape the colonization of concealed human cadavers, including variables such as insect size and stage of sexual maturity. 相似文献

The purpose of this study was to examine the extent to which work-life conflict and organizational support for work-life balance
are related to job satisfaction and turnover intentions for military law enforcement personnel. More specifically, 1203 members
of the United States Air Force Office of Special Investigations completed a survey that measured family-to-work conflict,
work-to-family conflict, perceptions of work-life support from the organization, support from immediate supervisors, and support
from peers. Work-to-family and family-to-work conflict were related to job satisfaction and turnover intentions. Perceived
social support, especially at the organizational level, was negatively correlated with work-to-family and family-to-work conflict.
Agents within the OSI were experiencing more work-to-family and family-to-work conflict than OSI support staff although the
relationships among support, conflict and satisfaction were the same for the two groups. 相似文献

Inhalation exposure from vapor intrusion has become a priority over the past several years for federal, state, tribal, and local environmental agencies. This article discusses the identification of vapor intrusion conditions and mitigation approaches for large commercial and industrial facilities. Factors to be considered in the design and implementation of remedial measures to address source areas below a building include identification of source areas, access to the sources, feasibility of active remedial technologies to address the source area, and whether a remedial technology will be effective in reducing or eliminating the potential for vapor intrusion into the overlying building. In the event a mitigation system is deemed appropriate, the key factors to be considered in the design and construction of such systems include size and construction details for the building; uses and occupancy type; and type of heating, ventilation, and air conditioning (HVAC) systems in the building and associated air exchange rates and operation and maintenance considerations. This topic will remain a priority for regulatory agencies and a key concern of building owners. 相似文献

This article describes four demonstration projects that strive to promote responsible behavior with respect to parenting, child support payment, and employment among incarcerated and paroled parents with child support obligations. These projects, conducted in Colorado, Illinois, Massachusetts, and Texas, with support from the federal Office of Child Support Enforcement and evaluated by the Center for Policy Research, led to a number of common outcomes and lessons. The projects revealed that inmates want help with child support, parenting, and employment and that prisons can be effective settings in which to conduct such interventions. Family reintegration programs were popular with inmates and may have helped to avoid the rupture of parent–child relationships commonly associated with incarceration. Although employment is the key to child support payment following release, rates of postrelease employment and earnings at all project sites were low and the employment programs were of limited utility in helping released offenders find jobs. Agencies dealing with child support, employment, and criminal justice need to adopt more effective policies with incarcerated parents including transitional job programs that guarantee immediate, subsidized employment upon release, child support guidelines that adjust for low earnings, and better training and education opportunities during incarceration. 相似文献
