This study investigated a multi-mediation model of the relationship between bullying behavior, peer victimization, personal identity, and family characteristics to adolescent depressive symptoms in 194 high school students, 12–18 years of age. In the first model, peer victimization mediated the relation between bullying behavior and depressive symptoms. In the second model, personal identity mediated the relation between peer victimization and depressive symptoms. In the final model, the two mediation models were combined. The relative influence of family characteristics on all variables in the two mediation models was studied using structural equation modeling. The results supported both mediation models and confirmed the influence of family characteristics on all variables in the mediation models. This study indicates that victimization by one’s peers has consequences for adolescents’ psychological health when their personal identity is affected. In addition, the study was able to model several processes in which family characteristics were related to adolescent depressive symptoms. Moreover, the final combined model (in which the two mediation models and the influence of family characteristics on all variables were confirmed) explained half of the variance in adolescent depressive symptoms.

Research examining the relationship between internalizing symptoms and antisocial behaviors has generally been cross-sectional in design. Thus, although extant data have substantiated a strong correlation between internalizing symptoms and antisocial behaviors, few studies have focused on describing the nature of the co-occurrence over time. This study examined the relation between growth in internalizing symptoms and longitudinal patterns of antisocial behavior in a sample of 283 inner-city males and their caregivers assessed as part of a longitudinal developmental risk study. Participants were assessed annually in four waves. Non-offenders and escalating offenders had lower levels of internalizing problems at wave 1 than did chronic minor and serious-chronic-violent offenders. Results revealed a developmental trend of decreasing internalizing problems across study years for most participants, as would be expected, with adolescents participating in serious, chronic, and violent patterns of antisocial behavior displaying greater internalizing problems than those participating in stable patterns of less serious or no antisocial behavior. Further, when there was escalation of seriousness and frequency of antisocial behavior, there also was increased internalizing problems relative to non-escalating juveniles. Results are discussed in the context of developmental psychopathology.

Community, demographic, familial, and personal risk factors of childhood depressive symptoms were examined from an ecological theoretical approach using hierarchical linear modeling. Individual-level data were collected from an ethnically diverse (73% African-American) community sample of 197 children and their parents; community-level data were obtained from the U.S. Census regarding rates of community poverty and unemployment in participants’ neighborhoods. Results indicated that high rates of community poverty and unemployment, children’s depressive attributional style, and low levels of self-perceived competence predict children’s depressive symptoms, even after accounting for demographic and familial risk factors, such as parental education and negative parenting behaviors. The effect of negative parenting behaviors on depressive symptoms was partially mediated by personal variables like children’s self-perceived competence. Recommendations for future research, intervention and prevention programs are discussed.

We explore the impact of social institutions on economic performance in Jamaica through a reinterpretation of the plantation economic model. In its original form, the plantation model fails to develop a causal link between the plantation legacy and persistent underdevelopment. Despite its marginalization, the model remains useful for discussions on growth and development. Consequently, we offer a reappraisal using the causal insights from Kenneth Sokoloff and Stanley Engerman. We use two examples to demonstrate how inequality encourages the formation of institutions that are inconsistent with growth, and an empirical analysis to confirm the hypothesized relationship between inequality, institutions, and economic development. Since inequality is expected to influence growth indirectly, we use a structural specification, which follows William Easterly’s recent test of Sokoloff and Engerman’s argument. Our reliance on a time-series specification is unique. We demonstrate that the expectation that, on average, inequality and growth is negatively related and that institutions may compromise growth are accurate for Jamaica, the most cited Caribbean nation in the current discourse. Our results carry several policy implications, including support for the recent calls in Jamaica for political restructuring. However, both the paucity of similar studies and the importance of the implications for sustainable growth and development demand further analyses.

The International Monetary Fund: A review of the recent evidence   总被引:1,自引:1,他引:0  
A review of recent quantitative studies on the International Monetary Fund reveals that much of the conventional wisdom is incorrect. Recent studies have demonstrated a new degree of methodological rigor, have drawn more heavily upon insights from political science, and have asked a number of new questions. We review studies of participation in IMF programs, design of IMF conditionality, implementation and enforcement of IMF conditions, conventional program effects and catalytic effects. At every stage, we find substantial evidence of the influence of major IMF shareholders, of the Fund’s own organizational imperatives, and of domestic politics within borrowing countries. We conclude that very little is known with certainty about the effects of IMF lending, but that a great deal has been learned about the mechanics of IMF programs that will have to be taken into account in order to obtain unbiased estimates of those effects.

The current controversy over the politicization of science by the Bush administration is, by definition, a political controversy. As such, it must be addressed by political measures as well as the administrative strategies that Dr. Lambright suggests. The administration's actions go beyond the bounds of "business as usual" and reflect the interests of its powerful constituencies, as well as the unease of many citizens with some scientific and technological advances. Scientists need to engage these citizens and take their concerns into account in order to build trust between the scientific community and the public, as well as to impede unscrupulous politicians from distorting scientific information to suit their purposes.  相似文献

Many scholars argue that citizens with higher levels of political trust are more likely to grant bureaucratic discretion to public administrators than citizens with lower levels of trust. Trust, therefore, can relieve the tension between managerial flexibility and political accountability in the modern administrative state. Unfortunately, there is little empirical evidence showing that trust is actually associated with citizens' willingness to cede policy-making power to government. This article tests theories about political trust and citizen competence using the case of zoning. Trust in local government is found to be an important predictor of support for zoning, but trust in state government and trust in national government have no effect. These findings suggest that trust affects policy choice and helps determine how much power citizens grant to local administrators.  相似文献

While there is a growing academic literature about mail-in ballots, there has been no serious academic research to date on overseas voters, even though the counting of overseas military ballots figured into the 2000 presidential election controversy. The participation of nearly 4 million overseas voters, both civilian and military, is governed by the Uniformed and Overseas Citizens Absentee Voting Act. The authors examine the reported perceptions of military and nonmilitary voters covered by this legislation using two surveys funded by the U.S. Election Assistance Commission, focusing on their perceptions of electronic means of transmitting voting materials. The authors find that civilian overseas citizens have a harder time registering and voting than military overseas citizens; that the key factor is the timely transmission of voting materials; and that, despite privacy concerns, electronic transmission of voting materials is viewed favorably.  相似文献
