This analysis assessed patterns of sexual experience, the order in which behaviors were initiated, and associated factors, among Latino and African American ninth grade students (average age 15.2) who self-administered audio-computer-assisted surveys on netbooks in classes at 10 Los Angeles–area public high schools. Lifetime experiences with vaginal and oral sex were most common (19% and 16%, respectively); fewer reported anal sex (6%). Of the 23% reporting any sex, 91% fell into four categories: 36% reporting both oral and vaginal sex; 23% vaginal only; 18% all three; and 13% oral only. Most sexually experienced students (88%) initiated with vaginal or oral sex (46% vaginal, 33% oral, 9% both same day). No dominant pathway of sexual onset emerged for those reporting all three types of sex. We found no evidence that oral or anal sex substituted for or delayed vaginal sex. Males, those with a current partner, and those reporting multiple partners were more likely than others to report all three sexual behaviors versus vaginal only (odds ratios [ORs] 2.0, 1.5, 3.0; p = .02, .06, < .01, respectively). Although vaginal intercourse dominated their early sexual behavior, one-fifth of sexually experienced students reported anal intercourse, highlighting the need for specific prevention messages surrounding this higher-risk behavior. 相似文献

In passing the Caregivers and Veterans Omnibus Health Services Act of 2010, Congress created a legislative mandate for the Veterans Administration (VA) to strengthen its program of support services for caregivers of veterans. As part of this expansion, the VA implemented a nationwide toll-free telephone Caregiver Support Line (CSL). The CSL is a single point of entry system to link caregivers to national and local services to support care of a veteran. This article describes the CSL and its role in supporting aging veterans and their caregivers, discusses social workers’ contributions to its development and implementation, and reports utilization data. 相似文献

This article discusses the importance of collaboration with suppliers and partners during research and development (R&D) technology projects. It details how this can be accomplished using the collaborative enterprise governance (CEG) concept to manage a technology project. CEG is based on the premise that parts of companies work with parts of other companies, which are reconfigured on dynamic bases according to a variety of different internal and external factors. This article presents an overview of the founding literature, the CEG and its methodology, and examples based at Jaguar Land Rover in the UK. CEG has been used here to explain why some technology projects have succeeded while others have done less well. This article concludes by offering new propositions, inducted through grounded theory, relating to the successful management of R&D projects, which should be picked up by future research studies in the area. 相似文献

The commercially successful Disney animated television series Recess featured a bold and physically active tomboy character in a leading role. Ashley Spinelli (referred to only by her surname) vocally disdained all things feminine. Spinelli’s nemeses were a clique of snobbish, scheming girly-girls, all of whom were also named Ashley. This dynamic is significant when read against the Walt Disney Company’s overall investment in discourses of normative femininity. It is also historically contingent with the ways in which North American popular culture has used the tomboy to address various perceived societal needs, including healthy lifestyles, masculine dominance and childhood innocence. The Recess episode “First Name Ashley” displays an androcentric and gender-entitled representation of girlhood, predicated upon the understanding that normative femininity is synonymous with cruelty. The liberatory possibilities in this representation are thereby compromised by the representation of female agency as dependent upon maintaining distance from femininity. 相似文献

College students are at high risk for human papillomavirus (HPV) infection, yet their knowledge and self-protective behaviors appear inadequate. Researchers who have measured HPV-related knowledge and behaviors in evaluating college intervention efforts pay secondary attention to black college students because this group generally represents only a small subset of samples of the broader college population. OBJECTIVE AND PARTICIPANTS: The authors' purpose in this study was to examine HPV-related knowledge and behaviors in 351 black undergraduates attending a historically black southeastern university in the spring of 2003. METHODS: Voluntary and anonymous student participation was solicited in randomly selected undergraduate classes. RESULTS: Results indicated that most students lacked HPV awareness (64%), became aware of HPV largely after infection, and gained their HPV knowledge from a health-care provider or college class. The authors performed an analysis by gender and found that women were more knowledgeable about HPV than were men. Observed HPV-related knowledge and behaviors were similar to samples of the broader US college population. CONCLUSIONS: Findings suggest a greater need for HPV intervention efforts for all college students, including those at black colleges. 相似文献

Equipment failures can have significant implications in terms of cost and customer satisfaction. Reducing the time required to find the cause of a failure can provide large cost savings and help preserve customer goodwill. Single‐item discrete sequential search models can be used to sequence the tasks in diagnostic search to minimize the expected time required to find the cause of the failure. We increase the utility of the single‐item discrete sequential search model by developing a formulation that includes simple precedence relationships as well as sequence dependent relationships defined by group activities. This formulation can be applied to a number of other problems including determining the sequence for multiple quality control tests on an item, scheduling oil well workovers to maximize the expected increase in oil production, and sequencing tasks in a research project where there is a technological risk associated with each task. 相似文献
