In recent years the validity of personnel systems has come to be more closely examined. This study focuses on one component of the police promotion system, the oral interview board. It examines the oral interview boards of a state police agency in which 161 state police troopers were aspiring for the rank of sergeant. Reliability and validity of the process are evaluated. The findings indicate that although the reliability coefficients were acceptable, significant differences in the ratings of similar types of raters across boards existed. Several statistical procedures were also used to investigate the validity of the procedure, but validity could not be established for this particular case. Several recommendations for improving the procedure are made.  相似文献

From March 1988 through September 1989, a demonstration study was conducted in Cuyahoga County, Ohio, on procedures for expediting paternity establishment. The issue of paternity establishment is central to current concerns about child support. In the 1988 Family Support Act, for example, administrative reforms to expedite paternity establishment are prominently featured. The results of the Cuyahoga demonstration provide early evidence of the likely impact of the 1988 reforms. At the implementation stage, the demonstration points up the complex interorganizational dependencies that are likely to limit the impact of mandated performance standards and associated sanctions directed at state and local child support agencies. As to the impact on paternity establishment outcomes, interventions directed at expediting administrative processes are likely to have a positive effect. However, the results of the demonstration indicate that noncooperative behavior among a significant portion of the client population is likely to seriously limit the effectiveness of expedited processes.  相似文献

American criminal law reflects the absence of any general duty of Good Samaritanism. Nonetheless, there are some circumstances in which it imposes affirmative duties to aid others. In those circumstances, however, the duty to aid is canceled whenever aiding subjects the actor to a certain level of risk or sacrifice, a level that can be less than the risk or sacrifice faced by the beneficiary if not aided. In this article, I demonstrate that this approach to limiting affirmative duties to aid encounters the same problem of moral arbitrariness as does a moral catastrophe override of deontological side-constraints.  相似文献

This study of 1228 parochial students in the eastern United States answered questions about adolescent sexuality. Few of the students surveyed claimed that sex was forced or even pressured. Over half of the students reported going steady as their relationship status when experiencing their first intercourse. Another fourth reported that they were dating or knew each other well. Approximately one-fifth of the students reported that drugs or alcohol was used at the time of first sex and three-fourths of them had first sex at either their own home or a friend's home. Nearly half of the students wished they had waited longer before having sex, especially the females and the more religious students. One-half of the nonvirgin students in the sample reported having had only one sexual partner. The implications of this information for setting social policy, designing and implementing effective sex education programs are discussed.Received Ph.D. in family studies/family science, Brigham Young University in 1994.
