HIV testing experiences of Aboriginal youth in Canada: service implications

The objective of this study was to explore HIV testing experiences and service views of Canadian Aboriginal youth in order to provide information for HIV testing services. An exploratory, mixed-method, community-based research design was used for this study. Findings reported here are from 210 survey participants who had experienced an HIV test. Youth were recruited through 11 Aboriginal organizations across Canada, including AIDS service organizations, health centers, community organizations, and friendship centers. Youth who had tested for HIV ranged in age from 15 to 30 years of age (20% were B20), and came from First Nations (75%), Me ́ tis (14%), and Inuit (9%) backgrounds. Participants lived in all provinces and one territory. Over half (62%) were female. While the majority of survey respondents indicated at their last HIV test they had been treated with care (80%), respect (77%), or kindness (76%), some reported being treated with hostility (19%), fear (12%), discrimination (11%), avoidance (10%), or being treated in a bored way (15%). When asked about information they had received, 28% of survey respondents could not remember; 23% said they were not given any information, and 24% said their questions were not answered. Emotional reactions to testing ranged from anxiety/apprehension (64% of survey respondents) to being ‘‘calm’’ (19%). When asked for suggestions to improve testing services, participants indicated emotional support, compassion, professional yet personable services, and personalized HIV information were important. Study results suggest that to facilitate HIV testing for Aboriginal youth, testing services and counseling must be respectful, compassionate, non-judgmental, and culturally responsive in order to provide emotional support and HIV information that is meaningful and memorable

Governing through community-based research: Lessons from the Canadian HIV research sector

AbstractThe “general public” and specific “communities” are increasingly being integrated into scientific decision-making. This shift emphasizes “scientific citizenship” and collaboration between interdisciplinary scientists, lay people, and multi-sector stakeholders (universities, healthcare, and government). The objective of this paper is to problematize these developments through a theoretically informed reading of empirical data that describes the consequences of bringing together actors in the Canadian HIV community-based research (CBR) movement. Drawing on Foucauldian “governmentality” the complex inner workings of the impetus to conduct collaborative research are explored. The analysis offered surfaces the ways in which a formalized approach to CBR, as promoted through state funding mechanisms, determines the structure and limits of engagement while simultaneously reinforcing the need for finer grained knowledge about marginalized communities. Here, discourses about risk merge with notions of “scientific citizenship” to implicate both researchers and communities in a process of governance

Entropy of Lovelock Black Holes

A general formula for the entropy of stationary black holes in Lovelock gravity theories is obtained by integrating the first law of black hole mechanics, which is derived by Hamiltonian methods. The entropy is not simply one quarter of the surface area of the horizon, but also includes a sum of intrinsic curvature invariants integrated over a cross section of the horizon.Comment: 15 pages, plain Latex, NSF-ITP-93-4

HIV and Rehabilitation Training Needs of Health Professionals in Canada: Results of a National Survey

Background: People with HIV experience a range of health-related challenges that rehabilitation services are well-positioned to address. The purpose of this study was to explore professional knowledge and views about HIV rehabilitation among HIV specialists and rehabilitation professionals in Canada.Methods and Findings: We conducted a nationwide cross-sectional postal survey with a random sample of rehabilitation professionals (physical therapists, occupational therapists, speech-language pathologists, and physiatrists) (N = 1058) and the known population of HIV specialists (physicians, nurses, social workers, pharmacists, psychologists, and dietitians) in Canada (N = 214). Two-thirds (67%) of rehabilitation professionals disagreed that rehabilitation professionals possess adequate knowledge and skills to assess and treat people living with HIV. The majority of all respondent groups felt that rehabilitation professionals who work with people living with HIV require specialized HIV training. Approximately one-third (32%) of rehabilitation professionals who had served people living with HIV stated they received some HIV training as part of their professional degree.Conclusions: This was the first national survey to explore HIV specialist and rehabilitation professionals’ knowledge and views about HIV rehabilitation. Findings indicate the need for interprofessional education, training, and mentorship of health professionals to address the gap between the needs of people living with HIV and rehabilitation services provision

Impact evaluation of a community-based intervention to reduce risky sexual behaviour among female sex workers in Shanghai, China.

BACKGROUND: Female sex workers (FSWs) are at risk for sexually transmitted infections (STIs), including HIV. We implemented an HIV/STI preventive intervention among FSWs in Shanghai that aimed to increase condom use, improve HIV knowledge, and reduce STI and HIV incidence. METHODS: From six districts in Shanghai, 750 randomly selected venue-based FSWs were allocated to either a behavioural intervention or control group. In the intervention and control groups, 221 and 278 participants, respectively, had at least one follow-up at three or six months. In analysis, we randomly selected 57 lost to follow-up cases in the intervention group and imputed baseline values to equalize the arms at n = 278 (74.1% follow-up rate in each group). The impacts of the intervention on condom use, HIV/STI risk perception and knowledge, and STI incidence were assessed using either a logistic or linear model, adjusting for the baseline measure of the outcome and venue type. RESULTS: The intervention improved consistent condom use with any partner type in the previous month (AOR = 2.09, 95% CI, 1.43-3.04, p = 0.0001). Consistent condom use with clients in the three most recent sex acts increased in both arms, and with primary partners in the intervention arm, but there was no difference between groups after adjusting for baseline condom use and venue type. There were no differences in cumulative incidence of any STI (i.e., chlamydia, gonorrhoea, syphilis) between groups. HIV transmission knowledge (p = 0.0001), condom use skill (p = 0.0421), and self-efficacy for using condoms (p = 0.0071) were improved by the intervention. HIV-related stigma declined (p = 0.0119) and HIV and STI risk perception were improved (4.6 to 13.9%, and 9.4 to 20.0%, respectively). The intervention was associated with these improvements after adjusting for the baseline measure and venue type. CONCLUSION: Following a preventive intervention among Shanghai FSWs, our findings demonstrate that a simple, community-based educational intervention improved overall condom use, HIV and STI knowledge, and attitudes in relation to HIV/AIDS. The intervention should be implemented widely after tailoring educational materials regarding condom negotiation with different partner types (i.e., commercial sex clients and primary partners)

Finding Correlations of the Oxygen Reduction Reaction Activity of Transition Metal Catalysts with Parameters Obtained from Quantum Mechanics

To facilitate a less empirical approach to developing improved catalysts, it is important to correlate catalytic performance to surrogate properties that can be measured or predicted accurately and quickly, allowing experimental synthesis and testing of catalysts to focus on the most promising cases. Particularly hopeful is correlating catalysis performance to the electronic density of states (DOS). Indeed, there has been success in using just the center of the d-electron density, which in some cases correlates linearly with oxygen atom chemisorption energy, leading to a volcano plot for catalytic performance versus “d-band center”. To test such concepts we calculated the barriers and binding energies for the various reactions and intermediates involved in the oxygen reduction reaction (ORR) for all 12 transition metals in groups 8–11 (Fe–Cu columns). Our results show that the oxygen binding energy can serve as a useful parameter in describing the catalytic activity for pure metals, but it does not necessarily correlate with the d-band center. In addition, we find that the d-band center depends substantially on the calculation method or the experimental setup, making it a much less reliable indicator for ORR activity than the oxygen binding energy. We further examine several surfaces of the same pure metals to evaluate how the d-band center and oxygen binding energy depend on the surface
