Engagement in school is crucial for academic success and school completion. Surprisingly little research has focused on the
relationship between student engagement and delinquency. This study examines whether engagement predicts subsequent school
and general misconduct among 4,890 inner-city Chicago elementary school students (mean age: 11 years and 4 months; 43.3% boys;
66.5% black; 28.8% Latino). To improve upon prior research in this area, we distinguish three types of engagement (emotional,
behavioral, and cognitive), examine whether the relationship between engagement and misconduct is bidirectional (misconduct
also impairs engagement), and control for possible common causes of low engagement and misconduct, including peer and family
relationships and relatively stable indicators of risk-proneness. Emotional and behavioral engagement predict decreases in
school and general delinquency. However, cognitive engagement is associated with increases in these outcomes. School and general
delinquency predict decreased engagement only in the cognitive domain. Suggestions for future research and implications for
policy are discussed. 相似文献

During the period of the Bush Presidency, the federal governmentproceeded to centralize and nationalize policy in major areasformerly controlled by states and localities. The extensionof federal goals and standards to such areas as education testing,sales tax collection, emergency management, infrastructure,and elections administration were among the areas of significantmandates and preemptions. The continuation of policy centralizationin areas under a conservative and unified political regime showshow strong and deep the roots are for centralizing policy actionsin our intergovernmental system. 相似文献

Some scholars argue that the author of the majority opinion exercises the most influence over the Court's opinion-writing process and so can determine what becomes Court policy, at least within the limits of what some Court majority finds acceptable. Other students of the Court have suggested that the Court's median justice effectively dictates the content of the majority opinion: whatever policy the median justice most wants, she can get. We test these competing models with data on Supreme Court decision making during the Burger Court (1969–86). While we find substantial evidence for both models, the agenda control model gains greater support. This suggests that opinions on the Court on each case are driven, in general, by the interaction of three key variables: the policy preferences of the majority opinion author, the policy preferences of the median justice, and the location of the legal status quo . 相似文献

We investigate the sources of an important form of social inequality: the social processes by which men and women acquire participatory resources in organizations. In particular, we investigate the extent to which men and women acquire civic skills and are targets for political recruitment within churches. Integrating theory about social interaction within an organizational structure, we hypothesize that the ways in which women gain politically relevant resources from the church are simply different from those of men. Three factors explain the institutional treatment of women in churches: (1) women's political contributions are devalued; (2) women respond to social cues more than men do; (3) women respond to political cues from clergy—especially female clergy—whereas men do not. Our findings of gender differences in civic resource acquisition provide a more nuanced treatment of the mobilization process and have broad implications for the relationship between political difference and participatory democracy . 相似文献

Some 25 years after the introduction of the first geo-information technologies in public organizations, strategies to manage their diffusion are still inadequate. This is problematic in light of the new generation of geo-information technologies that has become available and aims to invest in these new information technologies in order to advance e-government. This study questions how strategies for diffusion of geo-information technologies in public planning organizations can be improved. It shows that classic top-down management often enhances informal diffusion activities that deviate from the formal diffusion strategy. A knowledge management approach, in which geo-information specialists and planners participate in the formation of diffusion policies, can enhance the quality of the formal strategy, thereby preventing deviation and informal diffusion activities. The authors recommend that public planning organizations use this knowledge to improve their diffusion strategies for geo-information technologies. 相似文献

This special issue explores how one particular regional organisation, the Economic Community of West African States (ECOWAS), has defined certain transnational issues as security threats and how it has addressed them. In this introductory article, we begin by providing an overview and analysis of some of the most important transnational security challenges facing West Africa. Specifically, we discuss some of the problems raised by cross-border insurgencies, health challenges, organised criminal activities, terrorism and environmental degradation. We then examine the different levels at which actors have responded to these challenges. The section ‘Security culture: shaping the Economic Community of West African States (ECOWAS) response?’ sets out our approach to thinking about the concept of security culture and asks whether it might be relevant to understanding how and why ECOWAS has focused on responding to certain transnational security challenges and not to others. The final section provides an overview of the other articles in this issue. 相似文献
