ABSTRACTThe authors draw on two competing cultural perspectives—culture as values and culture in action—to examine the relationship between street codes and the propensity to violently victimize others. Specifically, they explore whether individual-level and school-level street codes, net of one another, are related to 3 types of violence: assault, robbery, and sexual battery. In addition, they consider whether these effects vary according to 3 contextual characteristics: (a) the location of the offending—in school versus out of school, (b) school-level economic disadvantage, and (c) school efficacy. Three-level ordinal logistic regression models are estimated using four waves of survey data from over 3,000 students nested within 103 schools. Results provide evidence that individual-level street codes are related to violent offending in a manner that is, largely speaking, not tied to context. However, there is some evidence that the effects of school-level street codes on offending differ between outside of school and in school settings and are conditioned by levels of school disadvantage and efficacy. Overall, some support is offered for both the culture-as-values and culture-in-action perspectives. 相似文献

Recent advancements in technology (e.g., social networking, texting) have created new ways for dating youth to relate to one another, including in abusive ways via “cyber dating abuse.” Cyber dating abuse is a form of teen dating violence that overlaps with other types of abuse (e.g., psychological) but also has several unique characteristics. Given the phenomenon’s limited presence in dating violence literature, we focus on identifying how experiencing cyber dating abuse relates to youths’ individual behaviors and experiences (e.g., substance use, sexual activity), psychosocial adjustment, school connection, family relationships, and partner relationships. A total of 3,745 youth (52 % female, 74 % White) in three northeastern states participated in the survey and reported currently being in a dating relationship or having been in one during the prior year. We found that experiences of cyber dating abuse were most significantly correlated with being female, committing a greater variety of delinquent behaviors, having had sexual activity in one’s lifetime, having higher levels of depressive symptoms, and having higher levels of anger/hostility. Further, cyber dating abuse appeared somewhat more strongly related to depressive symptoms and delinquency than did other forms of teen dating violence and abuse. 相似文献

Few studies have examined risk factors of childhood and early adolescent depressive symptomatology trajectories. This study
examined self-report depressive symptomatology across a 6-year time period from 2nd to 8th grade to identify latent groups
of individuals with similar patterns of depressive phenomena in a sample of 951 children (440 girls, 511 boys). Analyses,
using semiparametric group modeling (SGM), identified 5 trajectory groups for girls and boys: low depressed stables, low depressed
risers, mildly depressed stables, moderately depressed changers, and moderately depressed risers. Individual risk factors,
with the exception of shy/withdrawn behavior, were significantly different across trajectory group membership for boys and
girls, as was low-income status for boys. Boys in the low depressed and mildly depressed stable trajectory groups had significantly
higher levels of antisocial behavior, attention problems, and lower social competency compared to girls in similar groups.
These results suggest that universal prevention programs implemented in early elementary school that target selected risk
factors may be helpful in reducing future adolescent mental health problems, specifically depressive symptomatology. 相似文献

One means by which the state reinforces inequality is by imposing administrative burdens that loom larger for citizens with lower levels of human capital. Integrating insights from various disciplines, this article focuses on one aspect of human capital: cognitive resources. The authors outline a model that explains how burdens and cognitive resources, especially executive functioning, interrelate. The article then presents illustrative examples, highlighting three common life factors—scarcity, health problems, and age-related cognitive decline. These factors create a human capital catch-22, increasing people's likelihood of needing state assistance while simultaneously undermining the cognitive resources required to negotiate the burdens they encounter while seeking such assistance. The result is to reduce access to state benefits and increase inequality. The article concludes by calling for scholars of behavioral public administration and public administration more generally to incorporate more attention to human capital into their research. 相似文献

As a new world economy emerges what is being learned about the accompanying phenomenon of administrative corruption? To probe this question we combine study of current developments in China with prevailing theories of corruption. The administrative corruption experience, as it has unfolded during the economic development thrust of the Deng reform era, is described and analysed in a comparative context. In specifically interjecting the American experience we suggest that a balanced control response to corruption —rather than an elimination focus—could be a fruitful avenue for policy and research, and that informal, social approaches to corruption control are pregnant with possibilities. China's experience offers a significant opportunity to push the margin of wisdom on these issues as they relate to economic and political development. 相似文献

Although there has been evidence for some time of a sex difference in depression, relatively little research has examined the developmental process by which women come to be at greater risk than men for depression. In this paper, the developmental pattern of depressed affect is examined over early and middle adolescence, with a special focus on the patterns of boys as compared to girls. In addition, a developmental model for mental health in adolescence is tested for its power in explaining the emergence of gender differences in depression. Longitudinal data on 335 adolescents randomly selected from two school districts were used to test the hypotheses. Results revealed that girls are at risk for developing depressed affect by 12th grade because they experienced more challenges in early adolescence than did boys. The sex difference in depressed affect at 12th grade disappears once early adolescent challenges are considered.This research was supported in part by grants MH30252/38142 to A. Petersen.
