Jail and prison populations in the United States have continued to grow unabated during the past two decades but crime rates have not declined. Partly in response to the pressures caused by burgeoning correctional populations, the use of alternatives to incarceration has expanded. An ongoing debate centers on the effectiveness of these alternatives. Many criminal justice professionals and some researchers question whether such alternatives seriously restrict the criminal justice system 's ability to incapacitate the active offender. This study deals specifically with two alternatives to incarceration: probation and parole. We examine offender recidivism for a sample of probationers and parolees active in New Orleans, Louisiana, and offer a new approach to addressing the effectiveness issue. Past research has evaluated the effectiveness of alternatives by examining failure rates of diverted offenders. High failure rates, we argue, do not necessarily imply a significant loss of the incapacitative effects of imprisonment. We suggest that a more appropriate measure of the loss of incapacitative effect is the proportion of all offenses committed by persons on probation or parole. Our results suggest that such losses are surprisingly low. The policy implications of our findings are discussed.  相似文献

Postmortem examination of a former professional basketball player revealed an abnormal heart, most notably a single coronary artery. The literature on single coronary arteries is briefly reviewed, and the possible mechanism which caused the patient's condition is considered. This case is particularly unusual because of the patient's profession, which is so physically demanding.  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
