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.

Rethinking Timing of First Sex and Delinquency   总被引:1,自引:1,他引:0  
The relation between timing of first sex and later delinquency was examined using a genetically informed sample of 534 same-sex twin pairs from the National Longitudinal Study of Adolescent Health, who were assessed at three time points over a 7-year interval. Genetic and environmental differences between families were found to account for the association between earlier age at first sex and increases in delinquency. After controlling for these genetic and environmental confounds using a quasi-experimental design, earlier age at first sex predicted lower levels of delinquency in early adulthood. The current study is contrasted with previous research with non-genetically informative samples, including Armour and Haynie (2007, Journal of Youth and Adolescence, 36, 141–152). Results suggest a more nuanced perspective on the meaning and consequences of adolescent sexuality than is commonly put forth in the literature.

This cross-sectional study examined relationships between pubertal development, depressive symptoms and delinquency in a sample of 241 males and 213 females aged 9–13 years. Four objectives were set forth for this study: (1) to examine relationships between pubertal stage or timing and depressive symptoms and delinquency; (2) to compare continuous and categorical measures of pubertal timing; (3) to examine gender as a moderator of these relationships, and (4) to examine maltreatment as a moderator of these relationships. Results indicated that mature pubertal stage and early (continuous) pubertal timing were both related to higher delinquency whereas only early pubertal timing was related to depressive symptoms. Categorical timing was not related to depressive symptoms or delinquency. Neither gender nor maltreatment were found to be moderators. These findings provide evidence against equating pubertal stage, continuous timing, and categorical timing, and highlight the need to identify possible moderators in research on pubertal development.

Suicide is an important public health problem in China: It is the fifth leading cause of death in China, and suicide in China accounts for over 30% of the world's overall suicide deaths. The substantial burden due to suicide has not been well recognized. This study aims to provide an estimate of the socioeconomic burden of the suicide problem in China in terms of years of life lost (YLL) and to discuss its implications. Suicide rates and the related YLL by age, gender, and region (urban/rural) from 1990 to 2000 were estimated using the most recent data from the Ministry of Health of China. The suicide rate in rural China was three times higher than that in urban areas. Suicide completers in rural areas shared 90% of total YLL. Rural women aged 25-39 years contributed the largest share of YLL. Our results show that some population subgroups contributed a disproportionate share to the disease burden of suicide. National strategies for suicide prevention should include targeted programs in catering the need of these specified subgroups in China.  相似文献

Cosmopolitan democracy is one of the most debated models of transnational democracy. As a result of his prominence in this field, David Held has attracted much of the criticism and approval of this position. The critique and comment aimed at cosmopolitanism in general, and Held's work in particular, has provoked cosmopolitan advocates to respond, restate and develop their arguments. However, despite its considerable merit, this debate remains largely theoretical, and little has been done in terms of studying the realisation of cosmopolitanism in real-world settings. This article contributes towards the debate concerning the possibility of its actual application by mapping the principles of cosmopolitan democracy in relation to the EU polity and the issue of gender equality. It argues that the EU articulates certain cosmopolitan-comparable principles, and by studying areas where they are clearly exhibited, such as the issue of gender, that this helps us to critically evaluate their practicability and enables a response to criticisms levelled at cosmopolitan democracy. This article addresses two specific criticisms. Firstly, in view of the justiciable qualities of EU law, and its ability to give rise to formal individual rights, it is argued that claims regarding the inherently fictitious nature of cosmopolitan rights are unfounded. Secondly, while acknowledging that civic engagement takes a principally legal mode in relation to the issue of gender, this article rejects the claim that cosmopolitan democracy neglects the political aspects of citizenship. However, cosmopolitan scholars must extend their understanding of the relation between rights and the wider aspects of citizenship engagement, if they hope to realise the vision of an active citizenry that remains central to the cosmopolitan project.  相似文献

The role of communication in public administration has been emphasized over time in public administration theory. Nonetheless, communication—with the exception of political communication—has been neglected in scholarship. Garnett's performance predicament posits the difficulty of showing linkages between communication and performance. This paper explores the role that communication plays in achieving organizational performance through a review of research that bears on communication's direct and indirect influences on performance. The primary thrust is communication's indirect role in achieving performance by mediating or moderating the effects of organizational culture on performance, thereby adding another perspective on the culture–performance relationship. Adapting the typology of Zammuto and Krakower, two types of organizational culture—rule-oriented culture and mission-oriented culture—are examined to explore how the relationship between organizational culture and organizational performance is influenced by communication. The analysis supports the claim that communication acts as a meta-mechanism for shaping and imparting culture in mission-oriented organizational cultures, thereby influencing performance. In particular, task orientation, feedback, and upward communication have positive effects on perceived organizational performance in mission-oriented organizations but potentially negative effects on performance in rule-oriented cultures.  相似文献
