Comprehensive community initiatives (CCIs) represent a popular method for creating systemic change, yet there is a dearth of evidence on their effectiveness (Zaff, Pufall Jones, Donlan, Lin, & Anderson, 2016). This article presents a systematic review of the evidence on the population-level impact of CCIs, focusing specifically on documented effects from studies using an experimental or quasi-experimental design. Of 1,947 articles identified through a database and hand search, 25 articles examining six different CCIs—most of which employed prevention science frameworks—met the review inclusion criteria. The results of this review show that CCIs can strengthen protective factors and reduce risk factors, delay initiation of and reduce substance use, and reduce the likelihood of, and delay engagement in, violent and/or delinquent behaviors. Impacts have been documented as soon as one year after initial intervention, and as early as 7th grade, with effects sustained as long as seven years post-intervention, and as late as a year post-high school. However, relative to the prevalence of CCIs as a practical intervention, the evidence base is small, potentially dated, and focused on a narrow set of outcomes and populations. Recommendations for interpreting the evidence base are discussed, including methodological limitations and implications for future work.  相似文献

The purpose of this study was to document whether adolescents make inferences regarding male and female vignette characters in terms of the characters' sexuality, social skills, impairment, and aggressiveness when the characters consume alcohol. A Web-based survey of 1,691 middle and high school students (grades 6–11) from diverse socioeconomic and ethnic backgrounds was conducted. The Dating Vignette and Subjective Perception Form ( George, Gournic, & McAfee, 1988 ) were modified for use with an adolescent sample and embedded within the Web-based survey. There were significant interaction effects between the male and female characters' alcohol consumption in terms of the respondents' perception of the female character for all of the subscales examined (i.e., sexual disinhibition, social skills, impairment, and aggressiveness). In contrast, there were no significant interactions between the characters' drinking and the respondents' perception of the male character. Collectively, these findings suggest that adolescents' perceptions of girls are based not only on the girls' own drinking behaviors, but also their male partners' drinking behaviors.  相似文献

Service-learning partnerships between universities and surrounding communities striving to create systems-level change must consider an emphasis in critical community service; a community centered paradigm where students are taught to work with communities to better understand contexts surrounding a social problem, as opposed to merely volunteering to provide a service to a community. The Adolescent Diversion Project (ADP), which has been operating for over 30 years, demonstrates critical community service through the type of relationship built between students and the local community. This article describes: a qualitative study with ADP students, the historical context of ADP, what and how students learned through their involvement in ADP, and reframes the work of this project as a form of service-learning pedagogy. Inductive content analysis was employed to identify underlying themes across participants related to their personal experiences of ADP and its impact in their lives. Findings were compared with service-learning outcomes and other quantitative studies conducted with past ADP cohorts from the literature. Consistent with past studies, ADP students become more negative toward social systems involved with their youth. This finding may explain an increase in feelings of political commitment following involvement in ADP. Consistent with service-learning outcomes, results demonstrate that ADP should be further documented as not only an effective community-based program but also as an exemplar in the pedagogy of service-learning. This study highlights why service-learning opportunities for students are not just one way to teach students, they are opportunities to bridge relationships within communities, bring life to theoretical concepts, and build the foundations necessary for educated citizens that will one day take lead roles in our society.  相似文献

Fundamental learning abilities related to the implicit encoding of sequential structure have been postulated to underlie language acquisition and processing. However, there is very little direct evidence to date supporting such a link between implicit statistical learning and language. In three experiments using novel methods of assessing implicit learning and language abilities, we show that sensitivity to sequential structure – as measured by improvements to immediate memory span for structurally-consistent input sequences – is significantly correlated with the ability to use knowledge of word predictability to aid speech perception under degraded listening conditions. Importantly, the association remained even after controlling for participant performance on other cognitive tasks, including short-term and working memory, intelligence, attention and inhibition, and vocabulary knowledge. Thus, the evidence suggests that implicit learning abilities are essential for acquiring long-term knowledge of the sequential structure of language – i.e., knowledge of word predictability – and that individual differences on such abilities impact speech perception in everyday situations. These findings provide a new theoretical rationale linking basic learning phenomena to specific aspects of spoken language processing in adults, and may furthermore indicate new fruitful directions for investigating both typical and atypical language development.  相似文献

Love and money, according to the intuitive logic of Christian political theology, stand in opposition to each other. Where economic relations obtain, relations of love are understood to be absent or distorted. The opposition between the two has led social theorists and political theologians—including John Milbank, Kathryn Tanner, and Daniel M. Bell—to understand Christian love as a reservoir of opposition to the politics of contemporary financialized capital. This opposition, however, ignores the complex interrelationship that has characterized Christian thought about love and money. Love and money—and their apparent competitive relationship—have been understood throughout the history of Christian thought on the basis of a relationship both maintain to the notion of indebtedness. This paper argues that any apparent tension between Christian theological caritas and oikonomia must to be contextualized in terms of a shared relationship between both of these concepts and the organization and administration of relations of debt and obligation.  相似文献
