Youths transitioning out of detention are particularly in need of support systems that can divert them from recidivism. This article examines the relationship between incarcerated youths' sense of their families' functioning and their perceived likelihood for postdetention success. Despite the control of background variables, results reveal that delinquents who indicated stronger familial functioning also reported a greater likelihood of future success. Although interventions that focus on improving the supportive capacity of families have shown great promise, treatment drop-out rates remain high. To explore incarcerated youths' view of family focused interventions, respondents rated the potential utility of family and nonfamily focused intervention options. A majority of respondents reported that family focused interventions would be helpful. A group of respondents, overrepresented by adolescents with low family functioning, reported that this type of intervention would not be helpful. These results are discussed in terms of their impact on offering family focused interventions for juveniles.  相似文献

Robotic extraction of DNA from dilutions of blood and semen using either the BioRobots EZ1 or BioRobots M48 consistently produced lower recoveries than standard organic extractions of the same samples. In an effort to increase the efficiency of robotically extracted DNA, glycogen and carrier RNA were added following cell lysis. The addition of glycogen, postlysis, resulted in no improvement in DNA recovery with the BioRobot EZ1. However, when carrier RNA was added to the cell lysate of limited and degraded samples extracted on the EZ1 or the M48, DNA recoveries dramatically increased four- to 20-fold. DNA yields obtained by robotic extraction in the presence of carrier RNA were as high, or higher, as those obtained by organic extraction lacking carrier RNA, while experiments that utilized carrier RNA in both types of extractions showed increased sensitivity for both methods. Furthermore, carrier RNA substantially increased the recovery of fragmented DNA with the EZ1.  相似文献

The utility of recidivistic prediction is limited by the false positive problem: predictions of failure (recidivism) that do not occur. False negatives (predicted successes but observed failures) are also worrisome, and together both types of error can be formally evaluated by what Blumstein, Farrington, and Moitra call the civil-libertarian ratio: the ratio of the subjective cost of a false positive to a false negative. Choice of a recidivistic criterion and selection of a proportion of offenders for criminal justice intervention have implications for the evaluation of the disutility or subjective cost associated with various civil-libertarian ratios. Logistic regression models of four recidivistic criteria are evaluated to demonstrate how base rate (observed failure rate) and selection ratio (proportion selected to fail) affect the disutility associated with a range of civil-libertarian ratios. Use of civil-libertarian ratios by criminal justice policy makers is demonstrated. Predictive utility is relatively difficult to achieve for rare recidivistic events if the decisions involve severe deprivation of liberty (incarceration decisions). Predictive utility is easier to achieve for more common forms of recidivism or in decision contexts where there is less concern for false positives, such as for “intermediate sanctions.”  相似文献

As federal government expenditures have grown, there has been an increasing awareness of the distribution of taxes and expenditures across states. States in the Northeast have claimed that sunbelt states have been getting more than their fair share of federal spending, with the sunbelt states denying the charge. A theory of political coalitions is developed to explain why the sunbelt should be unable to receive differentially high expenditures, although the sunbelt may pay less than a proportional amount in taxes because of its relatively low income. An empirical test shows that the data are in agreement with this theory.  相似文献

Disparate Measures: Public Managers and Performance-Measurement Strategies   总被引:2,自引:0,他引:2  
Over the past two decades, many studies have investigated the scope and significance of performance measurement in public organizations. Nonetheless, there is more to learn about the challenges facing public managers who want to measure organizational outputs and use the feedback to improve performance. Specifically, managers are often faced with redundant measures of the same output, each of which may be preferred by a different political principal or stakeholder. Furthermore, a manager's choice of measures can have serious consequences for both the estimation of agency problems and the success of programmatic solutions. We test these assertions in an analysis of educational organizations in Texas. We find that managers' assessments of organizational performance and decisions regarding solutions depend on the choice of performance measures.  相似文献
