The purpose of this investigation was to identify inmate personal and demographic data that may be used to further define or profile persons with a greater likelihood of being at risk for serving a jail sentence. This study was explorative. The survey administration was similar in format to that conducted by the U.S. Department of Justice. Chaplains were used as survey proctors. Pilot studies were conducted to determine the suitability of survey content. Surveys consisted of 172 items. Subjects included four hundred inmates: males comprised 88.75 percent of the sample, Caucasians 58.25 percent, Blacks 37 percent, Hispanics 3.25 percent and other 1.5 percent of the sample. Respondents ranged in age from 15 to 64 years with an average age of 30.3 years. Less than two percent of the contacted inmates refused participation in the survey. Results are presented for demographic data, select legal/criminal data, select drug and alcohol use data, employment data, health, parent/family data, education data, social data, and “other”.  相似文献

Conclusion The Regulations appear to have reinforced the protection available to software producers under United Kingdom law. The provisions of the Software Directive and the Regulations are complex and not without significant inconsistencies which are likely to prove to be a source of litigation. The drafters of the Regulations chose, unlike many of its European partners, not to adopt the wording of the Software Directive but to write their own interpretation, adding an element of uncertainty to the law in this area, which is perhaps inevitable bearing in mind the linguistic problems of translating and interpreting any directive coupled with the ambiguity and omission of definitions of several key terms. More important, however, than any academic argument will be the practical impact of the new law and its effectiveness in achieving its aim.  相似文献

This paper describes an effort by industry and university partners to centralize manufacturing decision making through the development of generic simulation tools. This ongoing, cooperative process improvement initiative between the Industrial and Systems Engineering faculty at the University of Alabama in Huntsville (UAH) and Chrysler’s Huntsville Electronics Division (HED) permits the involved faculty to broaden their experience and technical expertise in electronics fabrication, while the industry partner benefits from the transfer of technical knowledge and advanced analysis methodologies from the university. The focus of the project is the definition of generic electronic manufacturing models that can be easily defined and implemented through common user-oriented interfaces, allowing users who are not familiar with simulation and simulation languages to address the needs of their particular functional areas.  相似文献

Social scientists have theorized about the cycle of domestic violence in family abuse. Little research has addressed dating violence as a consequence to the experience of domestic violence by children. This article deals with the self-reported experience of dating violence by high school students from abusive and nonabusive households. A survey was conducted of 1,353 students in a rural area of North Dakota. Results indicated that students from abusive households showed significantly higher incidence of dating violence than those from homes where no abuse was evident. However, less than one in five of the students from abusive home reported dating violence, providing little support for the cycle of violence hypothesis. Students from abusive homes viewed violence as negatively as students from nonabusive homes. Thus, while there are significant differences between the two groups, there are also important similarities. Although there is apparently a greater risk of dating violence among students who have experienced violence at home, these data do not support the idea of an inescapable pattern of violence among adolescents who have experienced violence themselves.  相似文献

Conclusion We have in this paper tried to set out a framework which can facilitate analysis of the current and future situation of traditional rulership in contemporary African society. Our presentation of a proposed model for such an analysis is no doubt still in its elementary stages of formation. Much more work needs to be done. Nevertheless, our analysis has revealed certain salient elements and uncovered certain unresolved issues. If traditional rulers genuinely care about their own future they will have to devise techniques of legitimation which not only endear them to the government and the non-traditional elites, but also, and more importantly, to the mass of the people. True, the original role of the traditional rulers may be no more; still, it may be possible to salvage what is left.  相似文献
