This study examined family and neighborhood influences relevant to low-income status to determine how they combine to predict the parenting behaviors of Mexican-American mothers and fathers. The study also examined the role of parenting as a mediator of these contextual influences on adolescent internalizing and externalizing symptoms. Study hypotheses were examined in a diverse sample of Mexican-American families in which 750 mothers and 467 fathers reported on their own levels of parental warmth and harsh parenting. Family economic hardship, neighborhood familism values, and neighborhood risk indicators were all uniquely associated with maternal and paternal warmth, and maternal warmth mediated the effects of these contextual influences on adolescent externalizing symptoms in prospective analyses. Parents' subjective perceptions of neighborhood danger interacted with objective indicators of neighborhood disadvantage to influence maternal and paternal warmth. Neighborhood familism values had unique direct effects on adolescent externalizing symptoms in prospective analyses, after accounting for all other context and parenting effects.  相似文献

Community mobilization can increase the effective implementation of evidence-based practices (EBPs) in youth violence prevention. These strategies bring together people and organizations in a community to try to solve or reduce a problem. They help communities address the challenges of identifying EBPs, disseminating them to local decision-makers, and then implementing and sustaining them if they are successful. Science-based systems for implementing EBPs such as PROSPER and Communities That Care can help to integrate this complex work in communities. Further insight about implementing EBPs in youth violence prevention is being developed through the CDC-funded Academic Centers for Excellence in Youth Violence Prevention. Community mobilization approaches for seven of these programs are discussed, highlighting successful approaches and challenges encountered.  相似文献

About 10 % of infertile/subfertile women are diagnosed with diminished ovarian reserve (DOR), of which?<?5 % will become pregnant spontaneously. Fragile X (FMR1) genetic testing may provide a reason for her early ovarian aging and/or have reproductive implications. Seven women with DOR (genetic study subset) and the male partners of six of these women were separately interviewed about the experience of being asked to undergo this unanticipated genetic test. Three interviews were conducted (before, within 1 week after, and 3 months after learning the test results). None of the participants carried the FMR1 premutation (largest FMR1 allele 27–50 CGG repeats). For women, their pregnancy-seeking journey was long and exhausting. Women understood the reproductive implications of carrying the FMR1 premutation, and hoped for a negative result. Being offered a genetic test caused women to pause and re-think their future reproductive plans. Husbands viewed the infertility journey as filled with unknowns, of which the genetic test results would be one more puzzle piece. The expense of fertility testing/treatment was mentioned by both spouses, though more notably by husbands. The introduction of a possible genetic cause of infertility, with additional potential health consequences for future biological children, caused women to re-think their quest for pregnancy. In contrast, the genetic test was viewed as an additional source of information for their husbands as opposed to raising concern regarding potential reproductive ramifications.  相似文献

Can a virtuous person act contrary to the virtue she possesses? Can virtues have “holes”—or blindspots—and nonetheless count as virtues? Gopal Sreenivasan defends a notion of a blindspot that is, in my view, an unstable moral category. I will argue that no trait possessing such a “hole” can qualify as a virtue. My strategy for showing this appeals to the importance of motivation to virtue, a feature of virtue to which Sreenivasan does not adequately attend. Sreenivasan’s account allows performance alone to be a reliable indicator of the possession of virtue. I argue that, at least with respect to a classical, Aristotelian conception of virtue, this assumption is mistaken: a person is said to possess a virtue only when she is properly motivated. In my view, the nature of motivation required for the possession of Aristotelian virtue does not admit of blindspots. I am not primarily interested in details about the situationist critique of virtue theory but rather the implications that blindspots have for our conception of virtue. I argue that because the practical reasoning of the virtuous requires both cognitive and motivational coherence, the motivational structure of the virtuous agent cannot accommodate blindspots. My conclusion is neither a defense of motivational internalism nor of an idealized conception of Aristotelian virtue. My aim is to show that because blindspotted virtue does not cohere well with Aristotle’s conception of virtuous agency, friends of virtue theory must choose one or the other; they cannot have both.  相似文献

African Americans are overrepresented on the organ transplant waiting list and underrepresented among organ and tissue donors. One of the most highly noted reasons for lack of donation is the perception that donation is contrary to religious beliefs. The purpose of this cross-sectional study is to explore the complexities of religion (beliefs, religiosity, and religious involvement) and its association with willingness to donate and the written expression of donation intentions. Findings from a sample of 505 African American participants suggest that religion is a multidimensional construct and results differ depending on how the construct is measured and operationalized.  相似文献

Socially anxious individuals tend to have elevated levels of perfectionism and engage in excessive rumination following social situations. The present research aimed to examine perfectionism, in both state and trait forms, as a predictor of post-event rumination. Socially anxious students (N = 104) completed measures of trait perfectionism prior to, and state perfectionism following, an anxiety inducing speech task. Post-event rumination was assessed 2 days later. State and trait perfectionism were significant predictors of post-event rumination (2 days later), while controlling for baseline social anxiety, depression and state anxiety. These results support the need to target perfectionism in treatments for social anxiety disorder.  相似文献

Abstract

The relation of preschool and kindergarten children's vicarious emotional responding to their social competence, regulation (attentional and coping styles), and emotionality (negative emotional intensity and dispositional negative affect) was examined. Vicarious responding was assessed by means of facial reactions to a film about a peer in a social conflict and children's reported negative affect to viewing peers' real-life negative emotion. Mothers and teachers reported on children's regulation and emotionality, social competence was assessed with sociometric nominations, teachers' reports, and observations of children's real-life anger reactions. Facial concerned attention during the film was associated with various measures of social competence, regulation, and low or moderate negative emotionality. Although negative vicarious emotional responding in real contexts was infrequently related to measures of interest, girls who reported intense negative vicarious emotional responses were relatively unregulated and low in social competence. Finally, with age, regulation of vicarious emotional responding was increasingly related to children's sociometric status and to girls' coping at school. Thus, as they get older, children's abilities to regulate emotions may take on increasing importance in others' evaluations of their social competencies.  相似文献

Post-event processing is the cognitive rumination that follows social events in cognitive models of social anxiety. The aim of this study was to examine factors that may predict the extent to which individuals engage in post-event processing. Anxious rumination, social anxiety, anxiety sensitivity and post-event processing related to a recent anxiety-provoking social event were assessed in a college student sample (n = 439). Social anxiety and anxious rumination, but not anxiety sensitivity, significantly predicted the extent to which the participants engaged in post-event processing related to an anxiety-provoking social event. Factors that appear to impact on the post-event period include the nature of the social situation and the ethnicity of the participant. It appears that both general rumination over anxious symptoms, and specific rumination related to social events are relevant for cognitive models of social anxiety.  相似文献
