This study used data from 299 police officers from 12 municipal police departments across the state of Virginia to determine the relationship between education and police performance. Performance was measured by supervisor evaluations of each officer's overall performance, communication skills, public relations skills, report writing skills, response to new training, decision making ability, and commitment to the police department. Significant correlations were found between education and most measures of performance. Most importantly, the results show a significant correlation between overall performance and education (r=24, p.<001). The only variables not proving to be significantly related to education were objective measures of the volume of arrests, number of times the officer required discipline, and number of accidents. Interestingly, the benefits of a college education do not become apparent until police officers gain experience. In addition, police, officers with only a high school diploma decreased in overall performance after five years of experience.  相似文献

This article explores theoretical and empirical issues in the application of clinical neuropsychological evidence to forensic issues in the criminal law. The nature of forensic neuropsychological evaluations is discussed with reference to issues of competency to stand trial, criminal responsibility, and other competencies in the criminal process. Examples of specific disorders relevant to criminal law standards are presented, together with data estimating the prevalence of brain dysfunction in criminal and forensic populations. Research is also reviewed on the role of neuropsychological brain dysfunction in the etiology of violence and criminally relevant behavior. Finally, empirical and ethical issues concerning the applicability and admissibility of forensic neuropsychological data in the criminal context are discussed.  相似文献

The European Parliament has generally been deeply distrustful of the comitology system, primarily on the grounds that it allows the national administrations to undermine its supervisory role in the area of implementing legislation. Parliament has therefore sought to use the political, budgetary and jurisdictional means at its disposal to counteract the spread of comitology, or at least to promote the less intrusive forms of committee procedure. These initiatives have not, for the most part, been wholly successful; neither the interinstitutional agreements nor Parliament's arguments before the Court of Justice have produced the results it had hoped for. Parliament has been able, however, to use its Maastricht powers to influence the choice of committee procedure included in legislation adopted under codecision, and its budgetary tactics have forced the Commission to rationalise somewhat the annual expenditure on committees of all kinds and to bring a modicum of transparency into their operation. The imminence of the intergovernmental conference led to a suspension of hostilities towards the end of 1996.  相似文献
