The predictive accuracy of the newly developed actuarial risk measures Risk Matrix 2000 Sexual/Violence (RMS, RMV) were cross validated and compared with two risk assessment measures (SVR-20 and Static-99) in a sample of sexual (n= 85) and nonsex violent (n= 46) offenders. The sexual offense reconviction rate for the sex offender group was 18% at 10 years follow-up, compared with 2% for the violent offenders. Survival analyses revealed the violent offenders were reconvicted at twice the rate compared to sexual offenders. The RMV significantly predicted violent recidivism in the sex and combined sex/violent offender groups. Although the RMS obtained marginal accuracy in predicting sexual reconviction in the sex offender group, none of the scales significantly predicted sexual reconviction. An item analysis revealed four factors not included in the risk scales that were significantly correlated with sexual and violent reconviction. Combining these factors with Static-99, RMV, and RMS increased the accuracy in predicting sexual reconviction. 相似文献

The black soldier fly, Hermetia illucens (L.), is thought to colonize corpses 20-30 days postmortem. However, recent observations indicate this might not be true for all cases. Therefore, we conducted a study examining colonization by the black soldier fly and other Diptera on pig carrion in a plowed field in southern Georgia from 20 September through 21 February. Our data indicate black soldier flies could colonize a corpse within the first week after death. Knowing this information could prevent a serious mistake in estimating the time at which a corpse is colonized by this species. This study also represents the first record of Chrysomya rufifacies in Georgia. 相似文献

The present study examined the link between sexual orientation and adjustment in a community sample of 97 sexual minority
(gay male, lesbian, bisexual, and questioning) high school students, taking into account their experiences of peer victimization
and social support within peer and family contexts. Adolescents were identified in a large-scale survey study conducted at
5 high schools. They were matched to a comparison sample of their heterosexual peers. Sexual minority adolescents reported
more externalizing behaviors and depression symptoms than heterosexual youth. Compared to their heterosexual peers, sexual
minority youth reported more sexual harassment, more bullying, less closeness with their mothers, and less companionship with
their best friends. There were no significant differences between gay male, lesbian, bisexual, and questioning adolescents.
Overall, both victimization and social support mediated the link between sexual orientation and psychosocial symptoms. Among
sexual minority youth, the link between social support and externalizing was mediated by experiences of peer victimization.
These findings highlight the contextual risk and protective factors associated with non-heterosexual sexual orientation in
accounting for the emotional and behavioral problems in this population.

Political efficacy and trust—among the most frequently used survey measures of general political attitudes—are often maligned for their lack of reliability and validity. This paper reports results from the National Election Studies 1987 pilot study, which included more than thirty-five efficacy and trust items. Five attitudinal dimensions were hypothesized; four emerged clearly. One scale, internal efficacy, is especially robust; a four- to six-item scale represents a considerable improvement on existing NES measures. External efficacy is distinguished from political trust, at least when the former is measured in terms of the fairness of political procedures and outcomes rather than in terms of elite responsiveness to popular demands. Though less decisive, there also is support for dividing trust into incumbent- and regime-based components. The failure to find a similar incumbent- and regime-based distinction for external efficacy is in accord with theoretical perspectives.Revised version of a paper presented at the 1988 Annual Meeting of the Midwest Political Science Association. 相似文献

Although political discontent has risen substantially among Americans since the mid-sixties, there is considerable disagreement about the implications of this trend for individual political behavior and system performance. This paper develops a conceptual and theoretical framework within which this question can be examined. Two dimensions of political discontent, low diffuse support and external inefficacy, are hypothesized as motivations for political action when certain other conditions are met. In addition, because each of these orientations should be associated with different styles of political behavior, the mobilizing potential of political discontent may be greater than previous studies have indicated. 相似文献

Social programs have a wide variety of effects and often have the explicit objective of improving the economic status of the people they serve. In order to be useful to policymakers, benefit—cost analysis of social programs should explicitly take account of these two important program features. The approach used in this analysis of the benefits and costs of the Job Corps does this and provides a useful methodology for evaluating other social programs. According to the analysis, the program has substantial net value for society as a whole as well as for the average Corpsmember. 相似文献
