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

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

Little literature has been developed to describe the process of transferring a corporation's technology between international
units of that company for ultimate transfer to their external customers (Kimberly 1981 and Leonard-Barton and Sinha 1993).
This paper addresses the issues at Air Products and Chemicals, Inc. involved in the transfer of applications technology. Technology
is transferred from the unit of the corporation which develops the technology to international affiliates and subsidiaries.
The ultimate goal is the support of product sales to the external industrial customer. A strategy for this type of organization
is described which is supported by references to theoretical constructs in the literature and empirical observations from
the organization itself. 相似文献

This paper concerning the last 87 malpractice cases referred to the Department of Psychiatry and Law, Menninger Clinic, includes 57 suits against mental health practitioners and/or institutions, and 30 nonpsychiatric suits against general hospitals, surgeons, obstetricians, etc. A patient was available for interview in only 12 percent of the psychiatric cases; in 88 percent we reviewed medical records and consulted with attorneys. In the psychiatric cases the crucial question was whether a generally accepted standard of care was breached. The inherent problems of applying appropriate criteria to standards of care by practitioners and institutions are discussed. In half the psychiatric cases we found no significant deviation from acceptable clinical performance; in half we concluded that negligent practice had occurred. We did see a litigant for evaluation in 90 percent of the nonpsychiatric cases. The main issue involving them concerned harm or disability related to presumed negligence by medical personnel. How we evaluate such cases and apply disability criteria is discussed. 相似文献

The purpose of this study is to review 23 causes of death that have occurred in Western-Austrian prisons from 1974 to 1989. The majority of them (11 cases) were due to suicides. Among 9 cases of natural death there was a 25 years old man, who died of an unknown purulent meningoencephalitis. Two drunken prisoners had not been supervised and therefore died of alcohol poisoning. In one case the police jail physician did not recognize an epidural hematoma. 相似文献
