Long-Term Follow-Up of Young Children Placed in Foster Care: Subsequent Placements and Exposure to Family Violence 总被引:1,自引:0,他引:1

This study examined the quality or characteristics of permanent placements at 6 years of age for 254 children who had been removed from their homes prior to attaining 3.5 years of age (mean = 13 months). Although the primary objective when removing children is protection, subsequent permanent placements are prioritized by federal legislation with a stable family environment, especially one with the biological parent(s), being preferred. Three a priori comparisons (i.e., reunified vs. nonreunified, adopted vs. foster care, relative vs. nonrelative foster care) were conducted for caregiver and child reports of exposure to family violence. The results indicate that both reunified children and their parents report more family violence (witnessed and child victimization) than do nonreunified children and their caregivers. Adoptive parents did report that they used more minor violence in disciplining their children than did foster caregivers, but their children reported witnessing significantly less physical violence in the home. Recognizing that the development of children removed from their homes because of maltreatment is likely a function of both the maltreatment as well as the quality of subsequent family experiences (i.e., violence exposure), implications of the findings for determining placements are discussed. 相似文献

This article contends that routine activity theory has virtually ignored the motivated offender construct in terms of its
measurement. We extend previous research testing routine activity theory by more accurately modeling the effects of labor
market segmentation and other structural sources of offender motivation on variation in crime rates. A revised routine activity
model is tested using data for the 100 largest cities in the US in 1980. The findings suggest that as secondary labor markets
grow, urban crime can be expected to rise. 相似文献

The delivery of substance abuse treatment within correctional settings marks one of the criminal justice system's primary opportunities to disrupt the drugs-crime nexus. Federally funded residential substance abuse treatment programs were rapidly introduced across the nation, although implementation problems increased their operational variability. This article examines how implementation barriers interrelate with other types of obstacles and multiply to hinder determinations of program effectiveness. Specific barriers were identified from a case study of process and outcome evaluations of the South Carolina Residential Substance Abuse Treatment (RSAT) program. A conceptual framework groups barriers by type into four interrelated domains wherein additive effects and reciprocal consequences that can undermine effective program assessment are illustrated. 相似文献

This paper critically reviews the extensive literature on retrospective voting in response to economic conditions. Each of the major types of analyses which have been performed — time-series analyses of national vote totals, presidential popularity, and cross-sectional analyses of individual survey responses — has raised several interesting and important questions. The answers that have been obtained, however, are only partial and limited, as each of these approaches entails serious problems of estimation and interpretation. Further progress in this area, we argue, requires explicit treatment of conceptual and statistical issues that have hindered previous research: the dynamic formulation of expectations and preferences, the incidence of policy (and nonpolicy) effects across the population, and notions of incumbency and political responsibility. 相似文献

This article reports outcomes from a program of experimental research evaluating the risk principle in drug courts. Prior studies revealed that participants who were high risk and had (a) antisocial personality disorder or (b) a prior history of drug abuse treatment performed better in drug court when scheduled to attend biweekly judicial status hearings in court. In contrast, participants who were low risk performed equivalently regardless of the court hearings schedule. This study prospectively matches drug court clients to the optimal schedule of court hearings based on an assessment of their risk status and compares outcomes to clients randomly assigned to the standard hearings schedule. Results confirmed that participants who were high risk and matched to biweekly hearings had better during-treatment outcomes than participants assigned to status hearings as usual. These findings provide confirmation of the risk principle in drug courts and yield practical information for enhancing the efficacy and cost-efficiency of drug courts. 相似文献
