The psychological assessment battery is an integral part of the selection process used to select patrol officer applicants. Unlike all other procedures used in the selection process, the psychological assessment has not been adequately validated. The purpose of this study was an attempt to provide validation data for a psychological assessment battery. The battery consisted of the Nelson-Denny, Shipley-Hartford, MMPI, and the Motivational Analysis Test (MAT). Performance measures included various measures of training academy performance and field training performance. A stepwise regression and MANOVA/Discriminant Analysis indicated that the psychological tests did predict performance, although an exact predictive equation could not be developed due to the high intercorrelations between predictor variables. This research was sponsored in part by a grant from the School of Applied Arts and Technology, Southwest Texas State University.  相似文献

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

The conflict and animosity that sometimes accompanies child custody disputes can give rise to the propagation of allegations of child sexual abuse. To characterize the magnitude of the problem, the present study attempted to determine whether and to what extent child sexual abuse allegations predominate in family court litigation. The entire one-year caseload of a county family court docket was systematically reviewed and coded. Methodical evaluation of 603 family court files yielded base rates of pertinent allegations and other information profiling the cases. The findings did not support the contention that sexual abuse allegations are commonplace in child custody disputes. Sexual abuse allegations were made in 2% of cases in which custody or access was contested and in only 0.8% of the cases overal. Implications of the findings for future research were discussed.The authors gratefully acknowledge the assistance of the Honorable William R. Campbell and Barbara Scott, Clerk of Court for the South Carolina Fifth Judicial Circuit, as well as the contributions of Angie Newton, Frank Robinson, and Kimberly Ellis in the data collection process.  相似文献

“I Volunteer to Kidnap Ollie North”, is an exercise in following our government's sometimes criminal, often bizarre and always hypocritical actions in the war on drugs during the Reagan-Bush years to their logical conclusion. The Supreme Court has indicated in its June, 1992 decision in U.S. v Machain, that American law enforcement officers can now enter the sovereign territories of other nations to legally abduct violators of U.S. drug laws. Iran immediately proclaimed that they had the same right for violations of Islamic law. What might happen if kidnapping becomes a recognized “tool” of international law enforcement? What prominent Americans might wake up in South American jails with bags over their heads?  相似文献

Federal transportation officials assert that labor protections in the Urban Mass Transportation Act inhibit the propensity of local transit agencies to contract with private firms for services. The authors present results from a survey of a large sample of transit managers and econometric analysis to support their conclusion that labor protections do not appear to reduce the incidence of contracting. The labor protections, however, may be costly to transit management in other ways. The authors recommend actions, aside from repeal of labor protections, to increase contracting by local transit agencies.  相似文献

Compared to the practice in other professional schools and academic fields at universities, law professors are hired at a young age based primarily upon their academic merit determined through grades, class rank, and school rank. This emphasis upon narrowly defined academic merit—apart from achievement demonstrated through original scholarship or experience in professional practice—first emerged during "the professionalization of the American law professor" between 1870 and 1900 at Harvard Law School (HLS). Though normative today, this outcome was neither necessary nor uncontested. In the late nineteenth century the new standard of hiring faculty according to their academic merit was energetically opposed by those favoring the antecedent standard of professional experience and reputation. Only when financial considerations counterbalanced that traditional standard did hiring decisions tip in favor of the new principle. Not until the early 1900s, when the second generation of academic meritocrats dominated the HLS faculty, did the new hiring standard become unequivocally established as policy in the school and, by extension, in legal education.  相似文献
