An important national initiative in juvenile justice is Juvenile Offender Reentry (JOR). The renewed emphasis on offender reintegration has generated significant attention to juvenile justice practices, with the notable exception of juvenile confinement facilities. Juvenile detention and, to a lesser degree, juvenile corrections practitioners are involved but not invested in reentry, having made very few programmatic changes to accommodate JOR initiatives largely because these initiatives have been external to the institution and its staff. Yet, reentry is a powerful concept for juvenile facility practitioners, and the application of reentry principles could have a profound impact on daily operations. This article addresses a range of issues about investing juvenile institutions in reentry practices. Several reentry models are discussed along with their implications for daily operations and programs. 相似文献

In the current study the objective was to find to what extent a reliable determination of age at death is made possible by establishing the degree of aspartic acid racemization in the dentin of teeth. The results of the investigation of 46 teeth are in agreement with the values found by other authors. The method presented makes a reproducible and accurate estimation of age possible. We intend to elaborate and improve this promising method for determination of age at death. The relevant points are presented here. 相似文献

Quadratic pieces of fleece measuring 16 mm2 were soaked with 10 different blood-samples in the dilution steps of 1:1, 1:10, 1:100, 1:1000, respectively, and were tested in blood group typing and identification tests of forensic serology. The above spezified dilutions correspond with 5 microliters, 0.5 microliter, 0.05 microliter and 0.005 microliter of blood, respectively. The detection limit of the microspectrometric test for blood was the dilution 1:10, of the porphyrine test a dilution above 1:100, whereas the preliminary test for blood (peroxidase) succeeded always up to a dilution of 1:1000 and the species determination by the radial immunodiffusion test in agar gels succeeded in most cases op to a dilution of 1:1000. The detection limit of the anti-human globulin inhibition test was between the dilution steps 1:10 and 1:100 when non-titrated and undiluted anti-human globulin serum was used. Gc- and ABO-grouping were possible up to a dilution of 1:100 and were thus the most sensitive grouping systems. Phenotyping of the enzyme-systems and the Gm/Km-system usually required stains with considerably higher blood concentrations i.e. stains of undiluted blood. 相似文献

In 1990, the state of California passed the pioneering mandate on zero emission vehicles (ZEV). This technology‐forcing regulation is aimed at improvement of air quality and protection of public health from the adverse effects of air pollutants from automobiles. Facing severe opposition from the auto industry, the mandate has been revised a number of times, most recently in 2003, whereby the requirement for ZEVs have been made to align with the pace of technology development. Review of strategies used in implementation of the mandate has revealed greater emphasis on the economic incentives for rather than on environmental merits of ZEVs. Using prospect theory as the framework for analysis, the reasons have been explored. The findings of the study help us to understand how decisions are made with respect with to deviations from a mental anchor point and through the process of evaluation of losses and gains. 相似文献

Two conditions must be met in order for a person to be rightly considered the victim of a crime. First, there must be the victim of some form of harm. Second, the harm in question was the direct result of an act in which the harmed individual did not knowingly consent to take part. What are the dynamics of consent and how important should consent be in defining and placing criminal responsibility in crimes where women are sexually victimized? Finally, how does the conceptualization of victimization change when viewed from liberal and radical feminist perspectives? 相似文献
