Both parents and important non-parental adults have influential roles in promoting positive youth development (PYD). Little research, however, has examined the simultaneous effects of both parents and important non-parental adults for PYD. We assessed the relationships among youth-reported parenting profiles and important non-parental adult relationships in predicting the Five Cs of PYD (competence, confidence, connection, character, and caring) in four cross-sectional waves of data from the 4-H Study of PYD (Grade 9: N = 975, 61.1 % female; Grade 10: N = 1,855, 63.4 % female; Grade 11: N = 983, 67.9 % female; Grade 12: N = 703, 69.3 % female). The results indicated the existence of latent profiles of youth-reported parenting styles based on maternal warmth, parental school involvement, and parental monitoring that were consistent with previously identified profiles (authoritative, authoritarian, permissive, and uninvolved) as well as reflecting several novel profiles (highly involved, integrative, school-focused, controlling). Parenting profile membership predicted mean differences in the Five Cs at each wave, and also moderated the relationships between the presence of an important non-parental adult and the Five Cs. In general, authoritative and highly involved parenting predicted higher levels of PYD and a higher likelihood of being connected to an important non-parental adult. We discuss the implications of these findings for future research on adult influences of youth development and for programs that involve adults in attempts to promote PYD. 相似文献

Previous work on peer victimization has focused primarily on academic outcomes and negative indicators of youth involved in bullying. Few studies have taken a strength-based approach to examine attributes associated with bullies and victims of bullying. As such, we examined developmental trajectories of moral, performance, and civic character components, and their links to bully status using data from 713 youth (63 % female) who participated in Wave 3 (approximately Grade 7) through Wave 6 (approximately Grade 10) of the 4-H Study of Positive Youth Development. Latent growth curve analyses indicated that moral character was stable across waves, whereas civic character increased slightly by Wave 6. Trajectories for performance character varied; some youth alternatively displayed positive versus negative growth. Youth who reported bullying behavior reported lower initial levels of moral, performance, and civic character as compared to youth not involved in bullying. Bully–victims reported lower initial levels of moral and civic character as compared to youth not involved in bullying. Implications for future work examining character-related components in the context of peer victimization are discussed. 相似文献

Among Vincent Ostrom's many contributions to the study of public administration, policy, and political science, the concept of polycentricity remains his single most important legacy. This essay locates the origins of this concept in Ostrom's early research on resource management in the Western United States and demonstrates its continuing influence throughout The Intellectual Crisis in Public Administration, The Political Theory of a Compound Republic, and his other major publications. Although typically pigeonholed within the confines of the public choice tradition, Ostrom's body of work should be widely appreciated as an early statement of the critical importance of network forms of governance in democratic societies. 相似文献

Improving irrigation systems in Asian countries has been a high priority for the allocation of international aid. Substantial funds have been allocated to adopt the “best practices” of hiring external water engineers to construct modern systems to replace those that farmers built. These expensive investments have infrequently led to long-term improvement in the operation of irrigation systems in Asia. In this article, we examine the process and impact of an innovative irrigation assistance project that was initially undertaken in Nepal in the mid-1980s. We analyze data obtained over three time periods related to changes in system structure and performance over time. We trace the unfolding patterns of improved engineering infrastructure across time depending on the way it interacts with other factors to affect long-term irrigation performance. We examine some of the key variables that are likely to affect the diverse and complex patterns of change. We also undertake analysis of the configural impact of core variables using Qualitative Comparative Analysis (QCA). We find that the initial and later investments in system infrastructure are only one factor that helps to generate short-term improvement. Unless farmers encourage local entrepreneurs and organize themselves, create their own rules or use sanctions, and augment their rules through collective action, infrastructure investment alone is not sufficient to achieve sustainable higher performance. 相似文献

Eating disorders, and related issues (e.g., body dissatisfaction, weight control behaviors), represent pressing and prevalent health problems that affect American adolescents with alarming frequency and potentially chronic consequences. However, more longitudinal research is needed to elucidate the developmental processes that increase or maintain risk for, and that protect against, eating- and weight-related problems among adolescents. Accordingly, the current study used longitudinal data from 1,050 male and female (68.0 %) adolescents (Grades 9–11)—the majority of whom were European Americans (72.2 %)—who participated in the 4-H Study of Positive Youth Development to (a) describe trajectories of adolescents’ eating pathology and body dissatisfaction, (b) identify individual and contextual correlates of these pathways, (c) examine whether trajectories of eating pathology and body dissatisfaction related to adolescents’ depressive symptoms, and (d) elucidate whether sports participation moderated associations between specific trajectories of eating pathology and body dissatisfaction and adolescents’ depressive symptoms. Results suggest that the diverse pathways of eating pathology and body dissatisfaction that exist across middle adolescence, in combination with adolescents’ sports participation, have important implications for the positive and problematic development of our youth. In addition, the findings underscore the need to evaluate the interindividual differences that exist in regard to how sports participation may relate positively and negatively to developmental outcomes. 相似文献

Which firms oppose action to fight climate change? Networks of input sourcing and sales to downstream customers ought to propagate and reinforce opposition to decarbonization beyond direct emitters of CO2. To test this claim, we build the largest data set of public political activity for and against climate action in the United States, revealing that the majority of corporate opposition to climate action comes from outside the highest‐emitting industries. We construct new measures of the carbon intensity of firms and show that policy exposure via carbon‐intensive inputs and sales to downstream emitters explains this large volume of opposition from non‐emitting industries. Sixty‐six percent of U.S. lobbying on climate policy has been conducted by an extended coalition of firms, associations, and other groups that have publicly opposed reducing carbon emissions. Public opposition to climate action by carbon‐connected industries is therefore broad‐based, highly organized, and matched with extensive lobbying. 相似文献

AbstractChalmers Johnson's book Peasant Nationalism and Communist Power is important for several reasons. It is a complete reinterpretation of events of the Chinese revolution, presenting the revolution as merely another form of nationalist development of the modern nation-state. And it has had an enormous impact in the academic community. Most of the major works on this period of Chinese history are to some extent answers to Johnson. And its effect has extended beyond the field of Chinese studies. Almost all other studies of peasant mass movements and contemporary social change at least acknowledge Johnson's thesis and make some attempt to deal with it. 相似文献
