This study examined factors associated with youth remaining in extended foster care. Cohorts of youth in care in California at age 17 years were defined for the period from 2003–2012. Multivariable generalized linear models documented factors associated with remaining in care through age 19. Findings indicate that: a) the population of youth in care at age 17 has declined over time; b) youth in care at age 17 in 2012 were qualitatively different from those a decade earlier; c) a larger proportion of youth who do not exit to permanency are remaining in extended foster care; and d) although the characteristics of youth who remain in foster care as non-minor dependents continue to vary relative to those who age out, differences have diminished. Findings highlight the potential to target subgroups of youth who may benefit from the extension of care but are remaining in care at lower rates.  相似文献

Objectives

To conduct a meta-analytic review of selective and indicated mentoring interventions for effects for youth at risk on delinquency and key associated outcomes (aggression, drug use, academic functioning). We also undertook the first systematic evaluation of intervention implementation features and organization and tested for effects of theorized key processes of mentor program effects.

Methods

Campbell Collaboration review inclusion criteria and procedures were used to search and evaluate the literature. Criteria included a sample defined as at risk for delinquency due to individual behavior such as aggression or conduct problems or environmental characteristics such as residence in a high-crime community. Studies were required to be random assignment or strong quasi-experimental design. Of 163 identified studies published from 1970–2011, 46 met criteria for inclusion.

Results

Mean effects sizes were significant and positive for each outcome category (ranging from d?=?0.11 for academic achievement to d?=?0.29 for aggression). Heterogeneity in effect sizes was noted for all four outcomes. Stronger effects resulted when mentor motivation was professional development but not by other implementation features. Significant improvements in effects were found when advocacy and emotional support mentoring processes were emphasized.

Conclusions

This popular approach has significant impact on delinquency and associated outcomes for youth at risk for delinquency. While evidencing some features may relate to effects, the body of literature is remarkably lacking in details about specific program features and procedures. This persistent state of limited reporting seriously impedes understanding about how mentoring is beneficial and ability to maximize its utility.  相似文献

This paper summarises pilot work by Irise International to develop an acceptable and replicable solution to menstrual hygiene management (MHM) in East Africa based around the manufacture of a reusable pad. The paper presents a theoretical justification for the approach and the results of pilot work used to develop it, including baseline menstrual hygiene practices and their relationship to school absenteeism in schoolgirls in western Kenya, the short-term impact of training girls to make a reusable product on school absenteeism using a partial preference, parallel group randomised control trial, and an assessment of the acceptability of the approach.  相似文献

Research has reported that a strong risk factor for traumatic injury is having a previous injury (i.e., recidivism). To date, the only study examining the relationship between recidivism and homicide reported strong associations, but was limited by possible selection bias. The current matched case–control study utilized coroner's data from 2004 to 2008. Subjects were linked to trauma registry data to determine whether the person had a previous traumatic injury. Conditional logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs) for the association between homicide and recidivism. Homicide risk was increased for those having a previous traumatic injury (OR 1.81, 95% CI 1.09–2.99) or a previous intentional injury (OR 2.53, 95% CI 1.24–5.17). These results suggest an association between homicide and injury recidivism, and that trauma centers may be an effective setting for screening individuals for secondary prevention efforts of homicide through violence prevention programs.  相似文献

Abstract

Forty-three convicted sex offenders read each of four different offence vignettes that involved a man forcing a female victim into sex and the offender's subsequent police interview. The experimental manipulation involved giving participants each of four different scenarios concerning how the police interviewed the offender. These were interviews characterized by humanity, dominance, displaying an understanding of sex offenders’ cognitive distortions, or a neutral, control interview. Participants were required to rate the interviews on a variety of dimensions, such as the offender's likelihood of confessing, and the fairness of the interview. Where participants were told the man had been interviewed with humanity and compassion, they rated the offender as more likely to confess and rated the interview as fairer than the other conditions. In contrast, participants rated the offender interviewed with a dominant approach as less likely to confess, and for this procedure to be less fair than the other conditions. Displaying an understanding of sex offenders’ cognitive distortions appeared to have had no influence on perceived likelihood of confessions but was perceived to make the crime appear less serious.  相似文献

Abstract

Weapon focus is frequently cited as a factor in eyewitness testimony, and is broadly defined as a weapon-related decrease in performance on subsequent tests of memory for those elements of an event or visual scene concurrent to the weapon. This effect has been attributed to either (a) physiological or emotional arousal that narrows the attentional beam (arousal/threat hypothesis), or (b) the cognitive demands inherent in processing an unusual object (e.g. weapon) that is incongruent with the schema representing the visual scene (unusual item hypothesis). Meta-analytical techniques were applied to test these theories as well as to evaluate the prospect of weapon focus in real-world criminal investigations. Our findings indicated an effect of weapon presence overall (g= 0.53) that was significantly influenced by retention interval, exposure duration, and threat but unaffected by whether the event occurred in a laboratory, simulation, or real-world environment.  相似文献

Courts applying the persona torts – right of publicity, appropriation and false endorsement claims under the Lanham Act – often lack a precise methodology for determining whether a plaintiff has been depicted or identified. A number of courts have accepted the ambiguous notion that a defendant need only appropriate a plaintiff’s “identity.” Moreover, these courts apply an essentially impressionistic approach to whether that appropriation has occurred. This article, drawing from defamation doctrine, synthesizes a more nuanced and rigorous approach to the depiction question – an approach that also better safeguards important First Amendment values.  相似文献

Abstract

In Experiment 1 we examined whether children spontaneously alter the size of objects in their drawings of emotionally-laden events. To do this, we evaluated children's drawings of their own personal, past experiences. Children were asked to draw a picture of an event that had made them happy and an event that had made them sad. We found no differences in the size of object that children drew in their positive and negative emotional events. In Experiment 2, we asked adults with and without clinical training to discriminate children's drawings of happy events from their drawings of sad events. There was no difference in the accuracy of raters as a function of clinical expertise. Moreover, performance for both groups was at chance when we removed drawings with specific emotional indicators from the set (e.g. smiles or tears). We conclude that the emotional interpretation of drawings on the basis of the size of objects in that drawing is fraught with difficulty. We question the projective use of drawings in forensic and clinical practice.  相似文献
