The Youth Court in Schools Project was implemented in two low-income, violent, racially/ethnically diverse rural counties. This study examined if the presence of Youth Court impacted students’ perceptions of school danger, individual functioning, and interpersonal relationships. Data were gathered from 3454 youth; following multiple imputation, data were analyzed using paired samples t tests. Results indicated that perceptions of school danger increased significantly and self-esteem decreased significantly in the control schools pretest to posttest. Violent behavior, anxiety, friend rejection, and bullying victimization decreased significantly in the Youth Court intervention schools pretest to posttest, but did not change significantly in the control schools. Findings provide preliminary evidence that Youth Court is an effective way of improving school climate, individual functioning, and interpersonal relationships.  相似文献

A young person's first consensual sexual intercourse experience is often a remarkable and memorable experience. However, little systematic information exists regarding contextual factors of first intercourse, the affective salience of the experience, possible effects on sexual attitudes and beliefs, and subsequent sexual development and adjustment. This retrospective study aimed to examine these in a sample of 475 young adults. Overall, young men and women experienced intercourse for the first time around age 17, were in a committed relationship, and reported positive affective responses. Affective reactions to the first sexual intercourse experience, sexual self-efficacy, sexual aversion, and age at first intercourse affected individuals' current sexual adjustment; however, only sexual self-efficacy mediated between first intercourse and current sexual adjustment in young men and women. Older age at first intercourse was associated with less sexual self-efficacy and lower current sexual adjustment for women. This study provides initial data to suggest that the first sexual intercourse experience significantly impacts current sexual adjustment by affecting beliefs about sexual self-efficacy.  相似文献

This review summarises the research literature on children’s and parents’ involvement in social work decision making, which is regarded, in policy terms, as increasingly important. In practice, however, it tends to be messy, difficult and compromised. Different individuals or groups may have different understandings of participation and related concepts, while differences of age and disability also mediate effective user engagement. The literature highlights common themes in effective participatory practice with both children and their parents. Central to this are the establishment of relationships of trust and respect, clear communication and information and appropriate support to participate.  相似文献

Research in social psychology and criminology reveals a great deal of overlap when explaining the relationship between injustice and criminal or deviant behavior. The organizational justice literature examines how the major forms of justice (distributive, procedural, and interactional) combine and interact to influence criminal or deviant behaviors in the workplace. While general strain theory (GST) recognizes that injustice is an aspect of strain that fosters criminal coping in multiple contexts, it does not detail the additive and interactive effects that these types of injustice may have on crime. Nevertheless, GST can provide a useful theoretical lens for understanding how injustice facilitates criminal behavior. This article provides an overview of major findings regarding the relationship between injustice and crime according to a GST framework, concluding with a discussion of new directions for future research.  相似文献

This article examines the role that women’s cultures and communities have played in political protest and social change. We argue that women’s cultures, which form around the reproductive roles, labor, and emotional expectations placed on women, have been used to express femininity and as cultural resources or “toolkits” to transform male‐dominated spheres of society. We begin by defining women’s cultures, emphasizing that there is no universal women’s culture because the structural arrangements and cultural meanings of gender vary by race, ethnicity, class, nationality, and political context. We then review research that demonstrates the significance of women’s cultures for the collective identities and tactics deployed in social movements and protest, demonstrating how the study of women’s cultures and gender processes in social movements has contributed empirically and theoretically to understanding social movements. We examine women’s cultures and collective identities in communities as wide ranging as self‐help groups, lesbian communities, feminist organizations, and anti‐feminist groups. We then draw on prevailing theories of cultural change in globalization studies (cultural differentialism, cultural convergence, and cultural hybridization) to understand how women’s cultures have contributed to social change. We conclude by identifying future directions for the study of women’s cultures and social movements.  相似文献

In semi-arid cities, urban trees are often irrigated, but may also utilize natural water sources such as groundwater. Consequently, the sources of water for urban tree transpiration may be uncertain, complicating efforts to efficiently manage water resources. We used a novel approach based on stable isotopes to determine tree water sources in the Los Angeles basin, where we hypothesized that trees would rely on irrigation water in the soil rather than develop deep roots to tap into groundwater. We evaluated the oxygen (δ18O) and hydrogen (δD) isotope ratios of xylem water, irrigation water, soil water, and groundwater in a study of temporal patterns in water sources at two urban sites, and a study of spatial patterns at nine urban sites and one “natural” riparian forest. Contrary to our hypothesis, we found that despite frequent irrigation, some trees tap into groundwater, although in most species this was a small water source. Some trees appeared to be using very shallow soil water at <30 cm depth, suggesting that these mature urban trees were quite shallowly rooted. In the natural site, trees appeared to be using urban runoff in addition to shallow soil water. We were able to identify tree uptake of precipitation at only 3 sites. The results show that some irrigated trees utilize groundwater and do not rely solely on irrigation water, which may make them able to withstand drought and/or water conservation measures. However, some irrigated trees may develop very shallow root systems, which may make them more susceptible.  相似文献
