Scholars of congressional elections have argued that an increase in constituent diversity increases the level of electoral competition. Following models of boundedly rational candidates, we argue that there is strong reason to believe that the opposite is true. As the complexity of the electoral landscape increases, challengers will have a more difficult time locating an optimal platform when facing an experienced incumbent. Using data from the 2000 National Annenberg Election Study, we construct a novel measure of district complexity for U.S. House districts and test whether the entry of quality challengers and the incumbent's share of the two-party vote are affected by the complexity of the electoral landscape. We find strong support for the hypothesis that complexity benefits incumbents for both indicators of electoral competition, which stands in contrast to most of the existing literature on diversity and incumbent performance .  相似文献

Can a school or district improve student achievement simply by switching to a higher-quality textbook or curriculum? We conducted the first multi-textbook, multi-state effort to estimate textbook efficacy following widespread adoption of the Common Core State Standards (CCSS) and associated changes in the textbook market. Pooling textbook adoption and student test score data across six geographically and demographically diverse U.S. states, we found little evidence of differences in average achievement gains for schools using different math textbooks. We found some evidence of greater variation in achievement gains among schools using pre-CCSS editions, which may have been more varied in their content than post-CCSS editions because they were written for a broader set of standards. We also found greater variation among schools that had more exposure to a given text. However, these differences were small. Despite considerable interest and attention to textbooks as a low-cost, “silver bullet” intervention for improving student outcomes, we conclude that the adoption of a new textbook or set of curriculum materials, on its own, is unlikely to achieve this goal.  相似文献

In order to move beyond the existing push/pull framework to understand disengagement, we apply a systematic coding scheme derived from Mayer and colleagues' integrative model of organizational trust to examine why people leave extremist groups. In doing so, we also rely on in-depth life history interviews with twenty former left- and right-wing extremists to examine whether antecedents of distrust vary between the two groups. Findings suggest substantial similarities and important differences between left- and right-wing extremists' decision to leave. In particular, perceptions of poor planning and organization, low-quality personnel and vindictive behavior generate perceptions of organizational distrust and disillusionment. Although findings from the current study are based on a relatively small sample, notable similarities were identified between both groups regarding sources of distrust (e.g., leaders, group members). We also identified differences regarding the role of violence in weakening solidarity and nurturing disillusionment with extremist activities. We conclude this article with suggestions for future research that extend the study of terrorism and that may have significance for how practitioners address countering violent extremism initiatives.  相似文献

The involvement of adolescents with deviant peer groups is one of the strongest proximal correlates to juvenile delinquency and stems from a variety of causes. Past research has linked ineffective parenting with peer variables, including deviant peer group involvement and peer conflict during adolescence. In this study, adolescents’ appraisals of procedural justice within the family (adolescents’ appraisals of how fairly they are treated by parents in the process of resolving family conflict) were examined as one aspect of effective parenting that may relate to deviant peer group involvement in early adolescence. Data from 1660 middle school students (ages 11–14, mean = 12.6) indicated that higher appraisals by adolescents of procedural justice during family conflict resolution were related to lower levels of both peer conflict and deviant peer group involvement. A structural model was tested in which the relationship between adolescents’ appraisals of procedural justice in the family and deviant peer group involvement was partially mediated by measures of peer conflict. This model was found to have adequate fit to the data, indicating that part of the relationship between procedural justice appraisals and deviant peer group involvement can be explained by levels of peer conflict. Implications of these findings are discussed.

This longitudinal study examined whether supportive parenting mediates relations between parent–child differences in cultural orientation (generational dissonance) and depressive symptoms with a sample of 451 first and second generation Chinese American parents and adolescents (12–15 years old at time 1). Using a person-centered approach, meaningful typologies of cultural orientation were derived for fathers, mothers, and adolescents. Overall, results provided support, though qualified, for the notion that generational dissonance is linked to depressive symptoms through decreased supportive parenting. In general, having a parent with a bicultural profile seemed to be most advantageous if adolescents similarly had a bicultural profile, whereas more American oriented adolescents with more Chinese oriented parents reported the least supportive parenting and most depressive symptoms. Directions for future research and the benefits of using a person-centered approach in research of acculturation and generational dissonance are discussed.

Abstract

As the nineteenth century drew to a close, the Tibetan plateau in the eyes of the gentry and officials of Sichuan Province was little more than a defensive fence bolting the back door of the empire. Although a stone stele erected in 1727 proclaimed much of the Kham region of ethnographic Tibet to be under Sichuan's jurisdiction, its invested rulers were administered by a “loose rein” policy, leaving its polities effectively independent of Chinese authority, the borderland and its inhabitants being of little interest to the Qing state. Yet the turn of the nineteenth century marked the reenvisioning of the once-barren borderland as a resource-rich terrain worthy of industrial development and inhabited by a population in need of cultural transformation. This article examines the convergence of local and regional dangers and opportunities with the influence of absolutist notions of two newly globalizing norms, territoriality and sovereignty, a convergence that fostered this new vision of Kham as integral to the burgeoning Chinese state and nation. The ramifications of this transformation in perceptions of the former imperial frontier as “West” would resonate across China's western interior throughout the twentieth century.  相似文献

Very little is known about processes contributing to depressive experiences in American Indian youth. We explored the relationship between value priorities and depressive symptoms among 183 (65 % female) American Indian youth in grades 9–12. In addition, two potential moderators of this relationship were examined: value outcome expectations (i.e., whether one expects that values will be realized or not) and perceived community values. We found that American Indian youth who endorsed higher levels of tradition/benevolence values reported fewer depressive symptoms. However, the relationship between endorsing power/materialism values and depressive symptoms depended on the extent to which youth perceived their communities as valuing power/materialism. Finally, value outcome expectancies appeared to relate more strongly to depressive symptoms than did value priorities. Overall, these findings support tribal community efforts to impart tradition/benevolence values to American Indian youth but also emphasize the importance of attending to value outcome expectations and the perceived values of the community in understanding American Indian youth’s depressive experiences.  相似文献
