Prior studies have examined the influence of neighborhood perceptions on youth outcomes, but few studies have examined whose report of neighborhoods, parents’ or youths,’ are most important in predicting youth outcomes. This study addresses the relative associations of youths’ and mothers’ neighborhood perceptions with youth alcohol use and delinquency. The sample includes 499 mother-child dyads (youth age: 10 to 16 [mean=13.3; SD=2]). Structural equation modeling showed that youths’ perceived neighborhood problems were significantly associated with their delinquency but not their alcohol use. However, mothers’ perceived neighborhood problems were not related to either youth alcohol use or delinquency, suggesting that youths’ perceptions are better indicators of youth behavior. Youth reports may reflect their activities in the neighborhood and their exposure to different forms of deviance, so youths’ reports would be better indicators of exposure to neighborhood risk. Challenges for prevention are discussed. NIAAA Postdoctoral Fellow and Associate Research Scientist at the School of Public Health, University of California, Berkeley, and the Prevention Research Center, Pacific Institute for Research and Evaluation, Berkeley, CA. Her research interests include psychosocial and environmental factors influencing youth problem behaviors. Interests are interventions for children with substance use or externalizing problems and their families. She is currently conducting alcohol, drug and other risky behavior prevention studies that include a focus on young adults in club settings as well as a variety of different family-based studies in different geographic regions (San Francisco Bay Area, Alaska, Thailand). Her work integrates both quantitative and qualitative research methods and centers on alcohol and other drug use, and related health issues among adolescents and young adults. She is especially interested in applying theoretical models of socially learned behaviors to populations with different cultural and social backgrounds  相似文献

Health-based risk adjustment has long been touted as key to the success of competitive models of health care. Because it decreases the incentive to enroll only healthy patients in insurance plans, risk adjustment was incorporated into Medicare policy via the Balanced Budget Act of 1997. However, full implementation of risk adjustment was delayed due to clashes with the managed care industry over payment policy, concerns over perverse incentives, and problems of data burden. We review the history of risk adjustment leading up to the Balanced Budget Act and examine the controversies surrounding attempts to stop or delay its implementation during the years that followed. The article provides lessons for the future of health-based risk adjustment and possible alternatives.  相似文献

Using a simulated civil case, this experiment investigated whether mock jurors: (a) are able to disregard hearsay evidence when admonished to do so, (b) experience psychological reactance and "backfire effects" in proportion to the strength of judicial admonition instructing them to disregard hearsay evidence, and (c) are able to recognize and disregard hearsay evidence without judicial instructions. Results indicate that jurors were unable to disregard inadmissible hearsay testimony in some legal decisions regardless of whether there were judicial instructions to do so. Jurors exhibited backfire effects paying more attention to inadmissible hearsay evidence when they were strongly instructed to disregard it. More specifically, juror backfire effects were evident in both their confidence in their liability verdicts and in their punitive damage awards. The legal and policy implications of these findings are discussed.  相似文献

Personality disorder symptoms were investigated in a community sample of young people (n = 714) to assess their relationship over time with well-being during adolescence and the emergence of intimacy in early adulthood. Drawing on Erikson's theory of psychosocial development, changes in adolescent well-being were conceptualized as indirect indicators of identity consolidation. Cluster B personality disorder symptoms (borderline, histrionic, and narcissistic symptoms) were conceptualized to represent identity diffusion—i.e. maladaptive personality traits that usually resolve during the identity crisis of adolescence. Latent growth models were used in 2 age cohorts to assess (1) interrelationships between Cluster B symptoms, well-being, and intimacy at mean ages 13.8 and 18.6 years; and (2) associations between their developmental trajectories over the next 6 years. As expected, higher personality disorder symptoms were associated with lower well-being during adolescence, and declines in personality disorder symptoms over time were associated with corresponding gains in well-being. Consistent with Erikson's developmental theory, there was an inverse relationship between Cluster B symptoms and intimacy that increased in strength as young people entered adulthood. As an indicator of successful identity consolidation, well-being was significantly associated with intimacy in female adolescents and young adults.  相似文献

Two studies were conducted to explore psychological factors that contribute to the influence of inadmissible evidence (i.e., the backfire effect) on jurors' verdicts. On the basis of hypotheses derived from terror management theory, we predicted that reminders of mortality, in contrast to an aversive control topic, should lead participants to be less punitive when confronted with inadmissible (as opposed to admissible) evidence, when participants were either situationally induced or dispositionally prone to follow their personal sense of justice. In Study 1, control participants who scored high on a measure of nullification beliefs, and thus were prone to relying on their own sense of justice rather than the law, exhibited the backfire effect. However, reminding participants of their mortality reduced the damaging influence of inadmissible evidence. Study 2 extended these findings by showing parallel effects with a manipulation of nullification proneness via judicial instructions. The implications of these factors on the judicial process are discussed.  相似文献

Although the holding of founding and subsequent elections is essential for any transition from authoritarian to democratic rule, the comparative literature on electoral system design is limited on the experience of "Third Wave" democratizers. This is especially true with respect to the interactive effects between the choice of electoral system and the spatial, i.e., geographic, distribution of the vote—a critical factor that shapes electoral outcomes in all societies, but particularly in emerging democracies because many are plural and agrarian societies. Political elites in these countries have also rarely considered the impact of alternative electoral systems when selecting a system for their country. This article addresses these gaps in the literature and practice by presenting a computational model known as a spatial decision support system or SDSS that both explores these interactive effects and facilitates electoral design. The utility of the model is then demonstrated with data from Kenya and South Africa—two emerging democracies where issues posed by the spatial distribution of the vote have given rise to demands for redesigning or modifying the electoral system.  相似文献

In order to test the hypothesis that learning disabilities are related to juvenile delinquency, a sample of 1,005 public school and 687 adjudicated juvenile delinquent youths (ages 12 to 17) reported about delinquent behaviors in which they had engaged. The youths' educational records were screened, and, if the presence of learning disabilities could not be discounted, the children were given a series of tests. Every child was classified as either learning disabled or not. The results indicated that proportionately more adjudicated delinquent children than public school children were learning disabled. Self-report data, however, showed no differences in delinquent behaviors engaged in by learning-disabled and non-learning-disabled children, within either the adjudicated or public school samples. Public school children who have learning disabilities reported that they were picked up by the police at about the same rate as non-learning-disabled children, and engaged in about the same delinquent behaviors. Charges for which learning-disabled and non-learning-disabled adjudicated delinquents were convicted followed the same general patterns. In light of these findings, it was proposed that the greater proportion of learning-disabled youth among adjudicated juvenile delinquents may be accounted for by differences in the way such children are treated within the juvenile justice system, rather than by differences in their delinquent behaviors.  相似文献
