Dual-credit courses expose high school students to college-level content and provide the opportunity to earn college credits, in part to smooth the transition to college. With the Tennessee Department of Education, we conduct the first randomized controlled trial of the effects of dual-credit math coursework on a range of high school and college outcomes. We find that the dual-credit advanced algebra course alters students’ subsequent high school math course-taking, reducing enrollment in remedial math and boosting enrollment in precalculus and Advanced Placement math courses. We fail to detect an effect of the dual-credit math course on overall rates of college enrollment. However, the course induces some students to choose four-year universities instead of two-year colleges, particularly for those in the middle of the math achievement distribution and those first exposed to the opportunity to take the course in eleventh rather than twelfth grade. We see limited evidence of improvements in early math performance during college. 相似文献
This research note presents three newly interconnected and expanded datasets on interest groups’ (IGs) access to the Swiss political decision‐making process: (1) extra‐parliamentary committee seats occupied by IGs (1980, 2000, 2010), (2) parliamentary (committee) seats occupied by IG representatives (1992‐2015), and (3) consultation replies submitted by IGs (2008‐11). We show that the Swiss system of interest intermediation adapted to the multiplication and organizational consolidation of citizen groups, which defend non‐producer interests and do not provide selective benefits to their members (e.g. environmental groups). The share of access granted to citizen groups has increased in both the administration and parliament, across all federal departments and most legislative committees. Moreover, citizen groups benefit from a larger share of access in the recently revitalized parliament, compared to the administration. This suggests that economic groups’ decline in power is also related to the rise of citizen groups. 相似文献
The increased use of information and communication technologies (ICTs) has triggered enormous innovation in the public sector and created positive public value at the managerial, delivery of services, and policy levels. However, these positive outcomes do not automatically accrue simply by adoption of ICTs as public leaders can fail to adopt relevant new ICTs, use them poorly, or use them in ways that actually diminish public value, which raises the question of the importance of e-leadership. This article examines e-leadership and innovation capacity at the individual public manager level and fills in some gaps about the practice and implementation of ICTs in the public sector. We explore eight research questions useful in theorizing about e-leadership, develop constructs of e-leadership, and describe the current development of e-leadership. By comparing e-leadership in two country settings (South Korea and the United States), we also overcome the limitations of the existing Western-oriented studies about innovations in the public sector. In addition to the growth of e-leadership use and requirements for a variety of competencies equivalent to, but separate from, traditional communication competences, we find that national cultures exert significant influence on the major constructs of e-leadership, which implies that an effective e-leadership strategy should consider cultural contexts seriously. 相似文献
There is strong evidence that chronic, systemic inflammation hastens onset of the diseases of old age that ultimately lead to death. Importantly, several studies suggest that childhood adversity predicts chronic inflammation. Unfortunately, this research has been plagued by retrospective reports of childhood adversity, an absence of controls for adult stressors, and a failure to investigate various competing models of the link between childhood adversity and chronic inflammation. The present study was designed to address these limitations. Using 18 years of data collected from 413 African Americans (58% female) included in the Family and Community Health Study, hierarchical regression analyses provided support for a nuanced early life sensitivity explanation for the link between early adversity and adult chronic inflammation. Controlling for health risk behaviors and adult SES, late childhood (ages 10–12) adversity amplified the association between adult adversity (age 29) and chronic inflammation. This interaction operated in a domain-specific fashion. Harsh parenting amplified the relation between intimate partner hostility and inflammation, whereas early discrimination amplified the relation between adult discrimination and inflammation. These findings suggest that individuals may be primed to respond physiologically to adverse adult circumstances that resemble those experienced earlier in life.
Empathy, which is the ability to feel concern for and to understand others’ feelings, is thought to develop in high quality relationships with parent and peers, but also to facilitate the quality of these relationships. While a wide literature has addressed this aspect, the heterogeneity of primary studies, in which different indicators of relationship quality (e.g., support, conflict) and empathy (i.e., affective and cognitive) have been examined, makes it difficult to draw conclusive answers. Therefore, it remained ambiguous how parent–child and peer relationship quality are associated with adolescents’ empathy. In order to increase the understanding of these associations, a multilevel meta-analysis was performed, which allowed for including multiple effect sizes from each study. By a systematic literate search, 70 eligible studies were found that provided 390 effect sizes from 75 independent samples. The results showed a small positive correlation between parent–child relationship quality and empathy, and a small-to-moderate positive correlation between peer relationship quality and empathy, which was significantly stronger than the correlation with parent–child relationship quality. Hence, the meta-analytic results indicate that adolescents with higher quality relationships, especially with peers, indeed tend to show more concern for and understanding of others’ emotions than adolescents with lower quality relationships. Moreover, the moderation analyses showed stronger correlations for the positive dimension of relationship quality than for the negative dimension, and stronger correlations for composite scores of affective and cognitive empathy than for separate scores of the empathy dimensions. However, no differences in correlations were found between the affective and cognitive empathy dimension, and no moderation effects were found for gender and age. Thus, this meta-analysis demonstrates robust positive associations between parent–child and peer relationship quality and empathy in adolescence, implying that good empathic abilities may be a protective factor for experiencing poor relationships.
This article examines the relationship between leadership and public value, which is particularly challenging in a context of explicit contest and conflict. The theoretical framework is illustrated through a case study of policing rural crime. The study reveals that the police worked with multiple and competing publics rather than a single homogeneous public, and that part of their leadership role was to create and convene a public space in which different voices and divergent views could be expressed. The study notes that research needs to pay attention to the loss and displacement of public value, not solely its creation and recognition. The need to convene multiple publics required the police to lead, as part of a leadership constellation, and with political astuteness. The findings have wider relevance for other public services, and for studies of leadership and public value at the intersection between the state and civil society. 相似文献
