Ethnic group differences in the contributions of self-definition (self-worth and efficacy) and interpersonal relatedness with parents and peers to changes in psychological and school adjustment were examined among 448 White, Black, and Latino girls and boys (11–14 years of age). Self-report questionnaires and school records were evaluated for socioeconomic and ethnic group differences in patterns of change over 1 year. Overall similarity in changes over time across ethnic groups was found for relatedness, self-definition, and psychological adjustment, although Black and Latino youth reported more overall adjustment difficulties, Black youth reported less positive relationships with parents, and lower SES youth reported less positive peer relationships than others. Ethnic group differences in changes to school adjustment, even after controlling SES, suggested a cultural variation in which often cited declines in school adjustment during middle school characterize White adolescents to a greater degree than Black or Latino adolescents. Ethnicity moderated associations of relatedness and self-definition with psychological and school adjustment such that Black and Latino youth appeared particularly vulnerable to experiences that threaten closeness and trust in relationships. Results pointed to potentially important situational and cultural differences in maladaptive and adaptive developmental processes across ethnicity.  相似文献

The central question of this article is why indigenous social movements formed electorally viable political parties in Latin America in the 1990s. This development represents a new phenomenon in Latin America, where ethnic parties have been both rare and unpopular among voters. Institutional reforms in six South American countries are examined to see if the creation and success of these parties can be correlated with changes in electoral systems, political party registration requirements, or the administrative structure of the state. The study concludes that institutional change is likely to be a necessary but not sufficient condition for the emergence and electoral viability of ethnic parties.  相似文献

September 11 was the catalytic event that clearly demonstrated that transportation security was a virtual myth. We had obviously overinvested in efficiency-based mechanisms and procedures while the security and safety standards provided by effectiveness considerations were being increasingly ignored. This article analyzes the increasingly dangerous situation as it unfolded and provides an Emerging Entrepreneurial Management and Public Policy Model designed to provide insights towards rebalancing our transportation security and public policy considerations as we attempt to design, implement, and pay for optimal security systems to deal with the terrorism threats we face in the early twenty-first century. Rebalancing the model and the equations will require increased focus, will, and skills. It will also be a lot more expensive . . . in both the private and the public sectors.  相似文献

This paper examines recent modifications in American policy toward the Republic of China (ROC or Taiwan). It contends that, while the George W. Bush Administration may have carried out a significant readjustment of US policy, available evidence suggests that it will not endorse any major upgrades in ties with Taipei during the foreseeable future. Like previous administrations, the Bush Administration now recognizes the value of engaging the People's Republic of China (PRC). This development holds important implications for the future trajectory of America's relations with Taiwan and the PRC and for peace and stability in the Western Pacific.  相似文献

During the last few decades, both policy practices and policy idioms have drastically changed. Concepts such as interactive planning, network management, stakeholder dialogue, deliberative democracy, policy discourses, governance, etc. have replaced older ones such as public administration, policy programmes, interest groups, institutions, power, and the like. Although we recognise the relevance and importance of this shift in vocabulary, we also regret related ‘losses’. We particularly regret that the concept of power has – in our view – become an ‘endangered species’ in the field of public policy analysis. We therefore will develop a framework to analyse power – being a multi-layered concept – in policy practices in this article. We will do so on the basis of the so-called policy arrangement approach, which combines elements of the old and new policy vocabularies. In addition, we draw upon different power theories in developing our argument and model. As a result, we hope to combine the best of two worlds, of the ‘old’ and the ‘new’ idioms in policy studies, and to achieve our two aims: to bring back in the concept of power in current policy analysis and to expand the policy arrangement approach from a power perspective.  相似文献

We empirically test the role of membership rules and voting schemes for climate change coalitions with the STAbility of COalitions model (STACO). The model comprises twelve world regions and captures long-run effects of greenhouse gas accumulation. We apply three stability concepts that capture the notion of open membership and exclusive membership with majority and unanimity voting. We show that exclusive membership leads to superior outcomes than open membership and that unanimity voting is preferable to majority voting in welfare and environmental terms. Our results suggest restricting membership in future international environmental agreements and they provide a rationale for unanimity voting as applied in many international organizations.  相似文献
