The Dayton/Montgomery County Criminal Justice Center is a first attempt at systematic personnel development for an entire criminal justice system on a regional level. Through its work in training and education, communications, career pathing and development, and system change, the Center has promoted the idea of an improved, symbiotic relatioship among the major branches of the criminal justice system, and has acted as a catalyst for needed systemic change. 相似文献

It has been an assumption common in voting research that candidates must offer and voters must perceive opposing stands on issues for those issues to have a rational influence on the vote. Though apparently reasonable, this assumption eliminates analysis of the rational impact of style in voter thinking. This article argues that style issues should not be so easily dismissed and were of some importance in the 1972 presidential election. First, the data indicate that voters considered style issues as important as position issues. Second, voters were able to detect differences between the candidates on certain style issues. Third, salient style issues and salient position issues are similar in their causal relationship to the vote. These findings lend support to the general conclusion that style issues are an important and rational element of voter deliberations and have several implications for the study of public opinion, the behavior of political leaders, and the adequacy of elections as mechanisms of governmental accountability.This is a revised version of a paper presented at the Annual Meeting of the Western Political Science Association in Phoenix, March 31-April 2, 1977. The data presented here were gathered under National Science Foundation Grant GS-35408, Robert D. McClure and Thomas E. Patterson, principle investigators. We would like to thank Professor Patterson and McClure for the use of their data and their helpful comments. 相似文献

Since the publication of Lovaas' (1987) impressive findings, there has been a proliferation of home-based behavior modification programs for autistic children. Parents and other paraprofessionals often play key roles in the implementation and monitoring of these programs. The Behavioral Summarized Evaluation (BSE) was developed for professionals and paraprofessionals to use in assessing the severity of autistic symptoms over the course of treatment. This paper examined the psychometric properties of the BSE (inter-item consistency, factorial composition, convergent validity, and sensitivity to parents' perceptions of symptom change over time) when used by parents of autistic youngsters undergoing home-based intervention. Recommendations for future research are presented. 相似文献

Minor soft tissues injuries are common in both adults and children who have had cardiopulmonary resuscitation (CPR). Potentially life-threatening injuries are rare. The pre-arrest history in a resuscitated adult often assists the pathologist to interpret autopsy findings. In contrast, an infant or child may not have a reliable history. In this situation, it may be difficult if not impossible to distinguish resuscitation injuries from pre-existing accidental or inflicted trauma. I describe two children who had significant autopsy-documented injuries initially attributed to abuse. The State filed murder charges against the caretaker in each case. However, further history and review of the medical records suggested that resuscitation rather than pre-arrest trauma caused almost all of the injuries. The State dismissed the charges in the first case. A jury returned a "not guilty" verdict in the second. It is essential to consider the entire history and not just autopsy findings when performing a death investigation. 相似文献

Extent, trends, and perpetrators of prostitution-related homicide in the United States 总被引:1,自引:0,他引:1

Prostitute women have the highest homicide victimization rate of any set of women ever studied. We analyzed nine diverse homicide data sets to examine the extent, trends, and perpetrators of prostitution-related homicide in the United States. Most data sources substantially under-ascertained prostitute homicides. As estimated from a conservative capture-recapture analysis, 2.7% of female homicide victims in the United States between 1982 and 2000 were prostitutes. Frequencies of recorded prostitute and client homicides increased substantially in the late 1980s and early 1990s; nearly all of the few observed pimp homicides occurred before the late 1980s. These trends may be linked to the rise of crack cocaine use. Prostitutes were killed primarily by clients, clients were killed mainly by prostitutes, and pimps were killed predominantly by pimps. Another conservative estimate suggests that serial killers accounted for 35% of prostitute homicides. Proactive surveillance of, and evidence collection from, clients and prostitutes might enhance the investigation of prostitution-related homicide. 相似文献

The release of insanity acquittees requires making informed decisions regarding both the presence and severity of an individuals' mental illness and the dangerousness of these individuals. This study evaluated the usefulness of employing structured assessments of mental health and violence risk factors in the conditional release decision-making process. All persons found Not Guilty by Reason of Insanity at East Louisiana Mental Health System, Forensic Division who underwent a review panel between July 1, 1997 and July 1, 1999 were included in this study. The Classification and Regression Tree analysis was utilized to arrive at cutpoints that would optimize the predictive ability of the decision tree analysis. The results indicated that the Community Outpatient Treatment Readiness Profile score was the strongest predictor -- all patients receiving a score of 62 or greater on this scale were recommended to remain at the facility. When women were recommended for release, it was to civil facilities and with moderate levels of symptoms. For males with moderate symptoms, low PCL-R scores were associated with recommendations for release, whereas high scores were associated with recommendations for continued commitment. Our data suggests that algorithms may be useful to governing bodies when making release decisions. 相似文献

This article analyses the Transfer of Undertakings (Protectionof Employment) (TUPE) Regulations 2006, which revoke, entirely,the TUPE Regulations 1981. As well as comprising the UK Governmentsresponse to the amending Acquired Rights Directive 1998/50/EC,they purport to fulfil a four-fold aim of increasing the coverageof TUPE in outsourcing situations; clarifying the law on transferconnected dismissals and when employees may agree transfer relatedchanges to employment conditions; providing for the supply bytransferors of employee liability information; and relaxingthe provisions of TUPE in insolvency situations to the extentpermitted by the Acquired Rights Directive 2001/23/EC. It isto be argued that some of these aims are realised in the newRegulations, and others not. And certain areas worthy of newregulation are ignored. What is ultimately apparent howeveris that the new Regulations cannot be taken to be an employerscharter. In some instances the new Regulations may breathenew life (and litigation) into the law. 相似文献
