This study tested a social-ecological model of adolescent substance use. Multilevel modeling was used to investigate how systems,
such as parents, peers, schools, and communities, directly influence and interact together to influence adolescent substance
use. Participants included 14,548 (50.3% female) middle school students who were 78.6% White, 5.4% Biracial, 4.8% Asian, 4.8%
Black, and 3.6% Hispanic. Participants completed a survey with scales assessing substance use, peer influences, parental influences,
and characteristics of their school and community. Hierarchical linear modeling (HLM) was used to consider the variation of
parental and peer influences on substance use and how schools and communities relate to both substance use and the relationship
between substance use and peer and parental factors. Results indicated that a positive school climate and a positive sense
of community were associated with less adolescent substance use and that a positive sense of community moderated the relation
between peer and parental influence on adolescent substance use, thereby acting as a protective factor.

Co-operation between researchers in the global North and South is critical to the production of new knowledge to inform development policies. However, the agenda-setting process is a formidable obstacle in many development research partnerships. The first section of this article examines how bilateral donor strategies affect collaborative agenda-setting processes. The second section explores researchers' motivations for entering into North–South partnerships; the obstacles that Southern researchers encounter in agenda-setting processes; and the strategies that they employ to ensure that research partnerships respond to their concerns. This analysis suggests that while strong Southern research organisations are best placed to maximise the benefits of collaboration, donors and researchers alike are well advised to recognise the limitations of this approach and use it prudently, because North–South partnerships are not necessarily the best way to advance research agendas rooted in Southern priorities. 相似文献

Prior research has demonstrated that participation in out-of-school time activities is associated with positive and healthy development among adolescents. However, fewer studies have examined how trajectories of participation across multiple activities can impact developmental outcomes. Using data from Wave 3 (approximately Grade 7) through Wave 8 (approximately Grade 12) of the 4-H Study of Positive Youth Development, this study examined patterns of breadth in out-of-school time participation in activities and associated outcomes in positive youth development (PYD), Contribution to self and community, risk behaviors, and depressive symptoms. We assessed 927 students (on average across waves, 65.4 % female) from a relatively racially and ethnically homogeneous sample (about 74 % European American, across waves) with a mean age in Wave 3 of 12.98 years (SD = 0.52). The results indicated that high likelihood of participation in activities was consistently associated with fewer negative outcomes and higher scores on PYD and Contribution, as compared to low likelihood of participation in activities. Changes in the breadth of participation (in particular, moving from a high to a low likelihood of participation) were associated with increased substance use, depressive symptoms, and risk behaviors. Limitations of the current study, implications for future research, and applications to youth programs are discussed. 相似文献

Minimal attention has been focused on difficulties for youth in residential care regarding building healthy dating relationships, despite the significant risks to this group of adolescents. This study provided a unique opportunity to conduct focus groups with youth in residential care on issues surrounding dating relationships. The majority of youth feedback centered on the themes of desiring support developing relationship boundaries, establishing trust in relationships, understanding the consequences of sexual activity, and having real world examples regarding dating relationships. The data were examined for differences between the genders and recommendations for next steps provided. 相似文献

This study used quantitative and qualitative data from a larger research project regarding foster parent experiences to examine the characteristics that predict a parent’s willingness to foster an adolescent. Data collected from closed- and open-ended items related to reasons for not fostering a teen were also analyzed. Findings suggest parents who are older and were a foster child themselves, increased the likelihood they would foster a teen. When discussing reasons for not fostering an adolescent, parents identified fears of problem behaviors and concerns about negative impact on other children; findings that were corroborated in responses to the open-ended comments. 相似文献

This paper outlines and discusses techniques for three stages in forecasting parliamentary seats from British opinion polls: adjusting and aggregating published vote-intention figures from across different polls; forecasting how public opinion might change before election day; and predicting the seat totals from the forecasted election-day vote shares. Specifically, we consider a state-space model for opinion polls which correct for house effects and other sources of survey error, the estimation of the historical relationship between polls and the election-day share of the vote, and a probabilistic approach to predicting the winner in each constituency. 相似文献

For most intimate partners, safety is an important goal and basic need. How a partner perceives safety has an impact on what
happens in the relationship, and this will in turn affect the responses from the other partner. Lack of safety can provoke
negative emotions and actions which can lead to relationship deterioration and violence. However, little is known about this
process from the insider’s perspective. In this study, constructivist grounded theory methods were used to analyze interviews
from individuals (n = 37) to better understand individual appraisals of relational safety. The results include a theory that illustrates the
process of relational safety and threat. This model articulates how certain relational conditions precede a perception of
safety or threat, which then leads to corresponding actions. Implications of the model include a focus on interaction and
context when assessing for safety and abuse, as well as the importance of self regulation. 相似文献

Using three interviews spanning 3 years, we identified intimate partner violence (IPV) classes and determined how class membership
changed over time amongst a sample of 217 mothers at-risk for child maltreatment that were enrolled in an early childhood
home visitation evaluation study. Data on perpetration/victimization, IPV type (verbal, physical, and sexual abuse and injury)
and severity were used to conduct latent class analyses at each time point. Latent transition analyses established the proportion
of mothers who changed classes over time. A three-class solution (minimal, moderate, and high IPV) was indicated at each time
point. All classes included mutual IPV. Partners used minor verbal abuse in the minimal class, minor and severe verbal abuse
and minor physical abuse in the moderate class, and all IPV categories in the high class. At each transition, 40 % or more
women moved from minimal to moderate or high IPV. This movement emphasizes the need to screen women frequently and develop interventions recognizing
the dynamic nature of IPV. 相似文献
