Major Depressive Disorder is a common mental illness with rates increasing during adolescence. This has led researchers to examine developmental antecedents of depression. This study examined the association between depressive symptoms and the interaction between two empirically supported risk factors for depression: poor recovery of the biological stress system as measured through heart rate and cortisol, and cognitive vulnerabilities as indexed by rumination and a negative cognitive style. Adolescents (n = 127; 49 % female) completed questionnaires and a social stress task to elicit a stress response measured with neuroendocrine (cortisol) and autonomic nervous system (heart rate) endpoints. The findings indicated that higher depressive symptoms were associated with the combination of higher cognitive vulnerabilities and lower cortisol and heart rate recovery. These findings can enhance our understanding of stress responses, lead to personalized treatment, and provide a nuanced understanding of depression in adolescence.  相似文献

Civic developmental theory anticipates connections between normative developmental competencies and civic engagement, but little previous research has directly studied such links. The current study sought to contribute to civic development theory by examining associations between emotional and sociocognitive competencies (empathy, emotion regulation, prosocial moral reasoning, future-orientation) and civic engagement (volunteering, informal helping, political behaviors and beliefs, environmental behaviors, social responsibility values, civic skills). Data came from a geographically and racially diverse sample of 2467 youth (Mage?=?13.4, Range: 8–20 years, 56% female). The results indicated that empathy and future-orientation significantly predicted nearly all forms of civic engagement, whereas emotion regulation and prosocial moral reasoning were uniquely associated with specific forms of civic engagement. Exploratory multi-group models indicated that empathy and emotion regulation were more strongly associated with civic engagement among younger youth and prosocial moral reasoning and future-orientation were more strongly related to civic engagement among older youth. The findings help to advance developmental theory of youth civic engagement.  相似文献

Peer victimization is a significant risk factor for a range of negative outcomes during adolescence, including depression and anxiety. Recent research has evaluated individual characteristics that heighten the risk of experiencing peer victimization. However, the role of emotional clarity, or the ability to understand one’s emotions, in being the target of peer victimization remains unclear. Thus, the present study evaluated whether deficits in emotional clarity increased the risk of experiencing peer victimization, particularly among adolescent girls, which, in turn, contributed to prospective levels of depressive and anxiety symptoms. In the present study, 355 early adolescents (ages 12–13; 53 % female; 51 % African American) who were part of the Adolescent Cognition and Emotion project completed measures of emotional clarity, depressive symptoms, and anxiety symptoms at baseline, and measures of peer victimization, depressive symptoms, and anxiety symptoms at follow-up. Moderation analyses indicated that deficits in emotional clarity predicted greater peer victimization among adolescent girls, but not adolescent boys. Moderated mediation analyses revealed that deficits in emotional clarity contributed to relational peer victimization, which, in turn, predicted prospective levels of depressive and anxiety symptoms among adolescent girls, but not boys. These findings indicate that deficits in emotional clarity represent a significant risk factor for adolescent girls to experience relational peer victimization, which, in turn, contributed to prospective levels of internalizing symptoms. Thus, prevention programs should target deficits in emotional clarity to prevent peer victimization and subsequent internalizing symptoms among adolescent girls.  相似文献

In recent years, universities have seen an increasing amount of activity in entrepreneurship and commercialization, not only for students, but for faculty as well. Traditionally, these initiatives have been separate, such that programs and curriculum have been focused on supporting just students or just faculty. In 2012, the National Science Foundation (NSF) launched the NSF I-Corps? program, an innovative funding program that not only offered principle investigators (PIs) funding, but also exposed PIs to an innovation/entrepreneurship curriculum as well. The University of Michigan (U-M) was one of the first two NSF I-Corps? Nodes funded in 2012 and has leveraged the program to catalyze the entrepreneurial ecosystem. This paper describes the growth of this entrepreneurial ecosystem since 1983, the call of entrepreneurship in the U-M College of Engineering and describes the role the U-M NSF I-Corps? program has played across the university. The paper concludes with lessons learned and recommendations to administrators and policy makers considering more active promotion of academic entrepreneurship and commercialization in universities.  相似文献

Eyeball protrusion is one characteristic that must be assessed/predicted in craniofacial identification methods of skull-face superimposition and facial approximation. Previously it has been suggested that average exophthalmometry values, as measured on living individuals, should be used. However, it is unknown if proptosis prediction can be improved beyond the accuracy obtained when using mean values. Some authors have suggested that relationships between exophthalmos, height, interpupillary distance, and interorbital distance exist and it has been reported that these latter variables can be used to estimate eyeball projection. However, crucial tests are yet to be conducted. This study measures these variables and tests the accuracy of exophthalmometry means, a previously proposed prediction equation, and newly derived regression equations to determine which methods provide the best results. Data indicate that variation in exophthalmos is fairly small and as such prediction from other variables, like body height, are weak; thus, exophthalmometry means currently offer the best practical method of prediction. It should be noted that up to 2 mm error from either side of the mean is expected for 68% of cases.  相似文献

We examine how political campaigns influence individuals’ levels of correct, incorrect, and don’t know responses and the gender gap in political knowledge during the 2000 American presidential campaign. Using data from the 2000 National Annenberg Election Survey (NAES), we demonstrate that as the campaign progresses the electorate provides more correct answers and fewer incorrect answers. Moreover, the political campaign significantly reduces (and possibly eliminates) the direct effect of sex on political knowledge. While the political campaign decreases the number of incorrect answers provided by both men and women, the number of correct answers provided by women increases. Our findings highlight the importance of the political campaign in determining relative levels of political knowledge for men and women.  相似文献

Recently published research contends that concern about immigration is weakening the British political system by creating distrust in the elites and institutions in this system. Some may challenge this finding because the public opinion data used to illustrate this relationship is limited to the period of the recent Labour government, raising the possibility that it was an artefact of that era and thus may no longer hold. Using the most recent round of the European Social Survey (2010–11), this paper investigates whether this finding holds in the present era. The findings indicate that under the current Conservative‐Liberal Democratic government, concern about immigration is still related to negative perceptions of the political system. This finding, along with those reported in previous research, points to potentially serious negative consequences for the functioning of the British political system, which are discussed in the concluding section of the paper.  相似文献
