Negative outcomes associated with adverse childhood experiences are well established, but little is known about protective factors that could promote positive adjustment among high-risk youth. This study examined the potential protective role of positive peer relationships in the association between adverse childhood experiences and school engagement among at-risk adolescents. Data were collected prospectively from birth until age 16 from 831 diverse adolescents (52.6% female; 54% African American, 24% Caucasian) who were at-risk for family violence and their caregivers. The significant and negative associations between adversities and school engagement outcomes at age 16 were mitigated by peer intimacy and companionship and exacerbated by peer conflict. The findings underscore the importance of fostering positive peer relationships for improving school engagement among at-risk adolescents.  相似文献

Although it is well established that victimization and delinquency are related, it is not clear how this relationship works, and victims and offenders are still often studied and treated as two distinct groups. General strain theory views victimization as a form of injustice, which can give rise to anger and eventually lead to delinquency. The authors examine victimization, in particular polyvictimization, as a criminogenic factor. Based on a sample of 1,400 youths 12–17 years old in Quebec (Canada), they examine polyvictimization in relation to delinquency as well as negative emotions that can result from victimization namely anger, depression, and posttraumatic stress. The findings show support for general strain theory and highlight the importance of anger for the relationship between victimization and juvenile delinquency.  相似文献

Premised on the understanding that domestic violence is a broad concept that encompasses a wide range of behaviors from isolated events to a pattern of emotional, physical, and sexual abuse that controls the victim, this article addresses the need for a differentiated approach to developing parenting plans after separation when domestic violence is alleged. A method of assessing risk by screening for the potency, pattern, and primary perpetrator of the violence is proposed as a foundation for generating hypotheses about the type of and potential for future violence as well as parental functioning. This kind of differential screening for risk in cases where domestic violence is alleged provides preliminary guidance in identifying parenting arrangements that are appropriate for the specific child and family and, if confirmed by a more in‐depth assessment, may be the basis for a long‐term plan. A series of parenting plans are proposed, with criteria and guidelines for usage depending upon this differential screening, ranging from highly restricted access arrangements (no contact with perpetrators of family violence and supervised access or monitored exchange) to relatively unrestricted ones (parallel parenting) and even co‐parenting. Implications for practice are considered within the context of available resources.  相似文献

Research on the governance of publicly funded research does not recognize that social science and 'science' are distinct activities. Neither does it recognize that regulating research policy in purely science and technology terms has undesirable consequences for the social sciences – intended or otherwise. This paper seeks to correct these omissions and considers the governance of social science through the example of regulating 'everyday epistemology' at the science policy level. The British research council system is used in order to demonstrate how social science has been politically constructed as a legitimate enterprise for public funding. We find that social science is in fact regulated by non-social scientists. The result is that social science, seen as a square peg, is forced into the round hole of natural scientific thinking. When this policy is translated into governance structures it creates a 'slave social science' and subverts the role of social science as social science.  相似文献

Innovation research has been characterized by findings which are either considered unstable or inconsistent. This article addresses some of the methodological issues that arise when one attempts to test interactive models of innovation, describes how one particular algorithm — AID-3 — can be used to refine the use of general linear models, and proposes a research strategy based on a building mode of innovation theory. As such it functions as a “how to” for those interested in designing innovation studies and also as a theoretical piece aimed at re-organizing the goals and outputs of innovation research.  相似文献

The purpose of these studies was to evaluate the performance characteristics of the Cozart Microplate Enzyme Immunoassay (EIA) for the determination of methadone in oral fluid from patients in a drug misuse treatment program. Oral fluid specimens were collected using the Cozart RapiScan Collection system from 198 donors who were receiving treatment for their addiction and were monitored for drug misuse. Oral fluid specimens were also collected from forty volunteer donors who were not drug users. The specimens were analyzed in the laboratory by EIA and then analysed for methadone and its main metabolite EDDP by gas chromatography-mass spectrometry (GC-MS). A total of 103 samples were confirmed positive for methadone. The Cozart Microplate EIA for d-Methadone in oral fluid using a cutoff of 30 ng/mL in diluted oral fluid had a sensitivity of 91.3% +/- 2.8% and a specificity of 100% +/- 1.0% vs. GC-MS.  相似文献
