This paper aims to review randomized experiments in criminology with offending outcomes and reasonably large numbers that were published between 1982 and 2004. A total of 83 experiments are summarized, compared with only 35 published between 1957 and 1981: 12 on policing, 13 on prevention, 14 on corrections, 22 on courts, and 22 on community interventions. Randomized experiments are still relatively uncommon, but there have been more large-scale multi-site experiments and replication programs. There have also been several experiments in which 100 or more places were randomly assigned. Relatively few experiments (only 10 out of 83) were conducted outside the United States. Meta-analyses suggest that prevention methods, correctional therapy, batterer programs, drug courts, juvenile restitution and deterrent policing were effective in reducing offending, while Scared Straight and boot camp programs caused a significant increase in offending. 相似文献

In this article a practical case is described when gunshot directions and position of a victim's body at the moment of each shot were determined by natural simulation using an LG-78 laser (made in the form of a gun). 相似文献

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

Workers Compensation claims are not interpersonal disputes. Almost always they are disputes between individuals and corporations. Compensation insurers are "repeat players" in the system. Workers are often "one–shotters" who have little or infrequent contact with the system. Power inequality between the worker, employer, insurer, and those who are required to facilitate negotiations and resolve and settle disputes under compensation legislation are matters of considerable importance. This paper examines the effects of the implementation, in 1993, of informal dispute resolution processes in the Western Australian workers compensation system under the Workers Compensation and Rehabilitation Act 1981(WA), which excluded lawyers from the process. It argues that preexisting power imbalances have been aggravated by these procedural changes, and in particular, by the exclusion of legal practitioners from the dispute resolution process. The issues raised herein have general application to most workers compensation systems. 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

Although past research has developed scales for the incidence, prevalence, and fear of student-on-student victimization (SSV),
little is known about the scaling of perceived risk (i.e., the cognitive appraisal of the chances of experiencing SSV). Hence,
this study examined self-report survey data for the perceived risk of SSV as measured in the Adolescent Index for School Safety
(AISS). Children in grades 7 through 10 (n=337) in a single Florida public school completed the AISS. Factor analyses using
Maximum Likelihood Estimation with Oblimin Rotation identified nine unique factors for perceived risk. Reliability analyses
found standardized Cronbach Alphas that ranged from .64 to .91, and seven out of the nine identified scales were above .80,
which suggested good to excellent internal consistency. Future research should examine the content validity, construct validity,
and predictive validity for the AISS and other self-report surveys of SSV dynamics.
