The University of Arizona chapter of Engineers Without Borders USA has faced multiple challenges involving community participation in rural development, in the Andean community of Marquirivi, Bolivia, both in rural design and in community participation. Despite successful construction of a shower house in 2014, the EWB-USA UA team experience with community participation revealed the numerous complexities involved in engaging successfully with communities. The importance of previous aid in a community with development projects also emerged as critical in shaping actions. This article discusses lessons learnt and recommendations for rural infrastructure projects, as well as the EWB-USA model of sustainable development.  相似文献

Psychological distress has been inconsistently associated with sexual risk behavior in youth, suggesting additional factors, such as substance use, may explain this relationship. The mediating or moderating role of substance use on the relationship between psychological distress and sexual risk behaviors was prospectively examined over the four high school years in a sample of urban youth (N = 850; 80% African American; 50% female). Growth curve modeling was used to estimate changes in sexual risk across adolescence and to test its association to psychological distress symptoms and frequency of substance use. Substance use was associated with psychological distress. Greater psychological distress was associated with increased sexual intercourse frequency, decreased condom use, and increased number of partners. Substance use fully mediated the relationship between psychological distress and intercourse frequency and condom use, and partially mediated the relationship between psychological distress and number of partners. We found no differences in mediation by sex or race/ethnicity and no evidence to support moderation of psychological distress and substance use on sexual risk. Findings suggest that psychological distress is associated with sexual risk because youth with greater psychological distress are also more likely to use substances. Practical implications for adolescent HIV/STI prevention are discussed.  相似文献

Nancy Alfaro is the quintessential practitioner of collaborative public management. More than that, she is a collaborative public manager focused on delivering customer service. Finding herself in the midst of a flurry of activity when San Francisco mayor Gavin Newsom suddenly ordered her to allow same-sex marriages in 2004, she pulled together the resources to perform more than 1,000 weddings in three days. Now, as director of San Francisco's 311 Customer Service Center, Alfaro oversees an operation that has reduced the number of telephone numbers residents may need to call for information and nonemergency services from 2,300 to just one. How Ms. Alfaro accomplished these remarkable tasks can be the source of fruitful lessons for other public officials.  相似文献

Research on the experiences of lesbian, gay, bisexual, transgender, and queer (LGBTQ) youth with LGBTQ parents is absent in the social science literature. The present qualitative, exploratory study utilized a social constructionist and queer theoretical lens through which to explore the sexual/gender identity formation and disclosure experiences of 18 LGBTQ young adults with lesbian/bisexual mothers. Findings suggest that LGBTQ parents may have a uniquely positive influence on their LGBTQ children in regard to their sexual and gender identity development. However, some participants reported perceiving societal scrutiny related to their mothers’ lesbian/bisexual identities and, thus, felt pressure to be heterosexual and gender-conforming. Furthermore, some participants did not necessarily utilize or view their lesbian/bisexual mothers as sources of support in relation to their own sexual/gender identity formation. While much more research is needed that examines the experiences of LGBTQ children with LGBTQ parents, this study represents a first step in addressing the existing literature gap.  相似文献

This study investigated genetic and environmental influences on the associations between mother–child relationship quality (warmth and hostility) and adolescent conduct problems and cigarette use. Participants included 601 mothers and adolescent twin pairs (aged 12–17 years). Mothers and adolescents provided separate reports of mother-to-child warmth and hostility. A combined measure of mother and adolescent reported conduct problems was used while adolescents provided reports of their cigarette use. Analyses were conducted using bivariate genetic analyses of correlated factors models and regression analyses of monozygotic twin differences. Genetic influences were found for most ratings of the parent–child relationship, with evidence of gender and/or rater-specificity for some measures. The relationship between mother–child hostility with adolescent conduct problems and cigarette use was influenced by genetic and environmental effects. Evidence was found for shared environment effects on the relationship between mother–child warmth and conduct problems. Examining monozygotic twin differences provided further support for non-shared environmental influence on the relationship between mothers’ expressions of hostility and low warmth and adolescent adjustment. Findings are discussed in relation to the interplay between genetic and environmental effects underlying links between parent–child relations and adolescent behavior problems.
