This study is based on repeated interviews with twelve heterosexual female commercial sex workers (SWs) in Perth. These informants deploy, with various degrees of success, strategies to demarcate ‘work-sex’, with its socially ascribed stigma, from ‘non-work sex’. Such strategies inhibit the spread of HIV at work but, ironically, increase the risk of HIV transmission during non-work sex. SWs recognise this risk and construct a variety of rationales to reduce their fear of contracting HIV and justify their strategies of demarcating work-sex from non-work sex. Efforts to reduce the risk of HIV infection among Perth SWs would seem to depend upon addressing not only these strategies of demarcation but these rationales in a supportive environment that recognises the creative complexities of their lives. 相似文献

ObjectiveTo undertake a systematic review of the literature to determine whether Asian ethnicity is an independent risk factor for severe perineal trauma in childbirth.MethodOvid Medline, CINAHL, and Cochrane databases published in English were used to identify appropriate research articles from 2000 to 2010, using relevant terms in a variety of combinations. All articles included in this systematic review were assessed using the Critical Appraisal Skills Programme (CASP) ‘making sense of evidence’ tools.FindingsAsian ethnicity does not appear to be a risk factor for severe perineal trauma for women living in Asia. In contrast, studies conducted in some Western countries have identified Asian ethnicity as a risk factor for severe perineal trauma. It is unknown why (in some situations) Asian women are more vulnerable to this birth complication. The lack of an international standard definition for the term Asian further undermines clarification of this issue. Nevertheless, there is an urgent need to explore why Asian women are reported to be significantly at risk for severe perineal trauma in some Western countries.ConclusionCurrent research on this topic is confusing and conflicting. Further research is urgently required to explore why Asian women are at risk for severe perineal trauma in some birth settings. 相似文献

OBJECTIVES: To examine public response to a telephone screener used to identify a probability sample of lesbians, gays, and bisexuals. METHODS: A telephone screener was designed to provide a representative sample of self-identified lesbians, gays, and bisexuals (LGB) in the 30 central cities of the 15 largest Consolidated Metropolitan Areas. RESULTS: Of 14,458 households contacted, 11,612 completed at least part of the survey. Of these, only 2.6% refused or responded "don't know" to the sexual orientation screener question. Respondents from the northeast were more reluctant to answer than respondents from the west. CONCLUSIONS: The use of a screener on a national telephone survey to screen households for self-identified lesbian, gay, and bisexual adults was a successful way to generate a representative sample. 相似文献

Background
Quick protective reactions such as reaching or stepping are important to avoid a fall or minimize injuries. We developed Kinect-based choice reaching and stepping reaction time tests (Kinect-based CRTs) and evaluated their ability to differentiate between older fallers and non-fallers and the feasibility of administering them at home.Methods
A total of 94 community-dwelling older people were assessed on the Kinect-based CRTs in the laboratory and were followed-up for falls for 6 months. Additionally, a subgroup (n?=?20) conducted the Kinect-based CRTs at home. Signal processing algorithms were developed to extract features for reaction, movement and the total time from the Kinect skeleton data.Results
Nineteen participants (20.2 %) reported a fall in the 6 months following the assessment. The reaction time (fallers: 797?±?136 ms, non-fallers: 714?±?89 ms), movement time (fallers: 392?±?50 ms, non-fallers: 358?±?51 ms) and total time (fallers: 1189?±?170 ms, non-fallers: 1072?±?109 ms) of the reaching reaction time test differentiated well between the fallers and non-fallers. The stepping reaction time test did not significantly discriminate between the two groups in the prospective study. The correlations between the laboratory and in-home assessments were 0.689 for the reaching reaction time and 0.860 for stepping reaction time.Conclusion
The study findings indicate that the Kinect-based CRT tests are feasible to administer in clinical and in-home settings, and thus represents an important step towards the development of sensor-based fall risk self-assessments. With further validation, the assessments may prove useful as a fall risk screen and home-based assessment measures for monitoring changes over time and effects of fall prevention interventions.10.
