This paper gives first an explanation for therapid development of Closed Circuit Television (CCTV)throughout Britain. This considers the implicationsof its rapid proliferation on the geographies ofpublic space and highlights the selectivity of thegaze of the surveillance cameras and the consequentpotential for the exclusion of certain groups frompublic space. The paper then extends this by usingresearch from two rural towns to address three basicquestions: how the cameras are used for direct lawenforcement; how this use is governed; and how thepublic react to the use of CCTV. It concludes that bystressing the selectivity of the surveillance anddrawing the implications of this for enforcement andgovernance, and also stressing the extent to which theplacing and timing of the use of the cameras fails toreflect the revealed preferences of the communitiesinvolved.  相似文献

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
