Objective: To conduct a pilot test of a brief, self-guided, home-based program designed to improve male condom use attitudes and behaviors among young women. Participants: Women aged 18–24 years from a large Midwestern University reporting having had penile–vaginal sex with two or more partners in the past 3 months. Sixty-seven enrolled; 91.0% completed the study. Methods: A repeated measures design was used, with assessments occurring at baseline, immediately post intervention (T2), and 30 days subsequent (T3). Results: Condom use errors and problems decreased, condom-related attitudes and self-efficacy improved, and experiences of condom-protected sex were rated more positively when comparing baseline with T2 and T3 scores. Further, the proportion of condom-protected episodes more than doubled between T1 and T3 for those in the lowest quartile for condom use at baseline. Conclusion: This low-resource, home-based program improved condom-related attitudes and promoted the correct and consistent use of condoms. 相似文献

Most research on the stability of adult relationships has focused on coresidential (cohabiting or married) unions and estimates rates of dissolution for the period of coresidence. Studies examining how the stability of coresidential unions differs by sex composition have typically found that same-sex female couples have higher rates of dissolution than same-sex male couples and different-sex couples. We argue that the more elevated rates of dissolution for same-sex female couples are a by-product of the focus on coresidential unions. We use data from the National Longitudinal Study of Adolescent to Adult Health to compare rates of dissolution based on the total duration of romantic and sexual relationships for same-sex male couples, same-sex female couples, and different-sex couples. Results from hazard models that track the stability of young adult relationships from the time they are formed demonstrate that male couples have substantially higher dissolution rates than female couples and different-sex couples. Results based on models restricted to the period of coresidence corroborate the counterintuitive finding from earlier studies that female couples have the highest rates of dissolving coresidential unions. This study underlines the importance of comparisons between these couple types for a better understanding of the role that institutions and gender play in the stability of contemporary relationships. 相似文献

A case-control study design was used to investigate risks of work-related physical assault (PA) associated with a history of violent victimization among educators. A total of 6,469 state-licensed educators (Kindergarten - Grade 12) worked in the previous 12~months and were eligible to participate. Exposure data were collected from cases (reporting a PA event in previous 12 months, n=290) for the month before PA, and from controls (no work-related PA in previous 12 months; n=867) for a randomly selected working month. Odds ratios and 95% confidence intervals identified increased risks for educators with any prior history of work-related (17.3, 11.4-26.3) or non-work-related PA (2.0, 1.2-3.5). In addition, PA risk in the previous twelve months increased with the number of previous victimizations, and risk also increased for educators with histories of non-physical violence (work- and non work-related). The results present a compelling case for targeted interventions and further research. 相似文献

We combine a variety of census and archival data to assess the relationships between social area characteristics and substance use. We found a substantial association between social area characteristics and substance use. We focus on intra and inter community, family, school and individual domain correlations to produce a prevention need-based score to rank communities from high to low need areas. Our analyses support the general risk and protective factor model advocated by Hawkins et al. (1992). As an important outcome of this work we suggest an objective criterion for selecting variables for the final model of the social indicators; suggest a set of weights for the selected factors and validate the selected factors with regard to substance abuse by linking the social indicator database to substance abuse outcome measures from another independent database. The selection criterion was based on intra domain correlations and proved to be robust. The weights were proportional to the information conveyed by each extracted factor. Analyses of intra-domain correlations are useful in identifying the types of prevention programs needed for each municipal area. Analyses of inter-domain correlations resulted in producing an overall need score based on social area characteristics. Many of the domains revealed more than one dimension, especially the school and the community/environment domains. Our analysis supports the use of social area characteristics in predicting the need for substance abuse prevention and treatment. It also suggests cautious and well informed decisions in selecting the indicators for a need based model. 相似文献

Geographical variability and network structure 总被引:1,自引:0,他引:1
In this paper, we explore the potential implications of geographical variability for the structure of social networks. Beginning with some basic simplifying assumptions, we derive a number of ways in which local network structure should be expected to vary across a region whose population is unevenly distributed. To examine the manner in which these effects would be expected to manifest given realistic population distributions, we then perform an exploratory simulation study that examines the features of large-scale interpersonal networks generated using block-level data from the 2000 U.S. Census. Using a stratified sample of micropolitan and metropolitan areas with populations ranging from approximately 1000 to 1,000,000 persons, we extrapolatively simulate network structure using spatial network models calibrated to two fairly proximate social relations. From this sample of simulated networks, we examine the effect of both within-location and between-location heterogeneity on a variety of structural properties. As we demonstrate, geographical variability produces large and distinctive features in the “social fabric” that overlies it; at the same time, however, many aggregate network properties can be fairly well-predicted from relatively simple spatial demographic variables. The impact of geographical variability is thus predicted to depend substantially on the type of network property being assessed, and on the spatial scale involved. 相似文献

Managing urban green space as part of an ongoing social-ecological transformation poses novel governance issues, particularly in post-industrial settings. Urban green spaces operate as small-scale nodes in larger networks of ecological reserves that provide and maintain key ecosystem services such as pollination, water retention and infiltration, and sustainable food production. In an urban mosaic, a myriad of social and ecological components factor into aggregating and managing land to maintain or increase the flow of ecosystem services associated with green spaces. Vacant lots (a form of urban green space) are being repurposed for multiple functions, such as habitat for biodiversity, including arthropods that provide pollination services to other green areas; to capture urban runoff that eases the burden on ageing wastewater systems and other civic infrastructure; and to reduce urban heat island effects. Because of the uncertainty and complexities of managing for ecosystem services in urban settings, we advocate for a governance approach that is adaptive and iterative in nature—adaptive governance—to address the ever changing social order underlying post-industrial cities and offer the rise of land banks as an example of governance innovation. 相似文献

We examine how an assistant coach's race and the race of his supervisor (the head coach) interact to affect future job quality. While past research argues that homophily is beneficial to job mobility, we find differential effects based on the race. OLS and OLR regression analyses on the quality of one's first head coaching job in NCAA men's basketball indicate that black assistant coaches working under black head coaches (black homophily) are significantly disadvantaged compared to all other racial combinations: white assistants with white supervisors (white homophily), white assistants with black supervisors (white heterophily), and black assistants with white supervisors (black heterophily). In contrast, there is no significant difference in job quality among the latter three groups: white homophily, white heterophily, and black heterophily. This indicates that while homophily is neither advantageous nor disadvantageous for whites, it is disadvantageous for black job candidates. This racially based disadvantage makes it difficult for minority job candidates to break through the glass ceiling and has real‐world financial implications. 相似文献

Between 1808 and 1848, under the terms of the Abolition Act, thousands of liberated Africans were distributed as apprentices to private citizens in the colony of Sierra Leone. In 1847, Governor Fergusson described apprenticeship, by that date primarily of children, as ‘a moral millstone round the necks’ of the colony's population. The Liberated African Department in particular was singled out by many contemporary European critics as unable or unwilling to monitor the whereabouts of apprentice children and to police the welfare obligations placed on apprentice-holders. This article explores a policy that was identified with widespread patterns of abuse, neglect and re-enslavement, and considers contemporary critiques in terms of underlying anxieties regarding the efficacy of humanitarian governance and the possibility of a post-slavery world. 相似文献
