Introducing the D4 Diagnostic Quadrant as a targeting tool: developing a framework for the effectiveness of HIV/AIDS interventions in Tanzania and beyond

The current study develops and evaluates a tool to distinguish four different categories of educators for the effective delivery of HIV/AIDS health education using data from 548 randomly selected participants aged 16 years. The D4 Diagnostic Quadrant is based on HIV knowledge and sexual practice behaviours and indicates four distinct typologies of educator. The discerning educator has high HIV/AIDS knowledge and healthy sexual practices. The dissolute educator has high HIV/AIDS knowledge but employs unhealthy or risky sexual practices. The decorous educator has low HIV/AIDS knowledge but practices healthy sexual practices. The disempowered educator has low HIV/AIDS knowledge and employs unhealthy or risky sexual practices. The study found that the two categories that will result in the most effective behaviour-change interventions are those that target ‘discerning’ and ‘decorous’ individuals as the educators. Both these categories have underlying healthy practices that minimise the risk of HIV transmission. The D4 Diagnostic Quadrant tool provides information as to existing knowledge and beliefs about HIV/AIDS that can inform decisions relating to the allocation of scarce resources. The tool will be very useful in the selection process of would-be educators particularly in health-promotion interventions.

Knowledge, risk perceptions and condom usage in male sex workers from three Australian cities

The study identifies factors associated with knowledge and perception of risk of HIV/AIDS, as well as attitudes to and usage of condoms by a sample of male sex workers (MSW). One hundred and eighty-five male sex workers completed a self-reported questionnaire, including knowledge about HIV transmission, attitudes to condom use and perceptions and personal susceptibility to HIV and sexually transmitted infection (STI) risk, and a two-week diary recording use of condom during commercial sex encounters. The findings reveal that condom use was found in 77.7% of the encounters with clients and the majority of the respondents perceived themselves to be at no risk for HIV because of sex work. Independent sex workers from Melbourne and workers who owned their place of residence used condoms in a significant lower proportion. Generally speaking, knowledge about the risks associated with AIDS was high, with respondents showing lower knowledge about the risks associated with unprotected receptive or active oral sex. Participants held a positive attitude to condom use; most considered the provisions of condoms to be their responsibility rather than clients; and they were more worried about contracting an STI than HIV. Those who scored higher on the knowledge scale had more positive attitudes to condom use and those who had a more positive attitude to condom use recorded a perceived lower risk of contracting STI but not HIV. The study discusses the relevance of these findings for public health risk reduction and sexual health education campaigns.

Knowledge synthesis, translation and exchange in public health and health promotion: the role of a Cochrane review group

The Cochrane Collaboration is an international non-profit organisation that aims to produce high quality systematic reviews of the effectiveness of health interventions. This work is conducted by 51 Review Groups that span a  range of topics (e.g. pregnancy and childbirth, HIV/AIDS). The role of Fields within the Collaboration has been to actively engage relevant stakeholders internationally to improve the quality and relevance of reviews. Since the inception in 1996 of the Cochrane Public Health and Health Promotion Field, the Cochrane Collaboration has begun to embrace reviews related to public health and health promotion and is adapting to the changing needs of end-users. The introduction of a Cochrane health promotion and public health review group will help ensure that reviews will be oriented towards building evidence for equity and reducing inequalities and best meet the needs of decision-makers, practitioners and consumers. Our role as a Field has led to us working with a range of partners including reviewers,  researchers, practitioners and consumers. Knowledge synthesis, translation and exchange (KST&E) has emerged as an issue in need of further  exploration for practice to influence decision-makers and for policy to  influence practitioners. 2007 will be an exciting year for evidence-informed Health Promotion and Public Health (HPPH) both within the Cochrane Collaboration and for our partners in policy, practice and research.

Commercial sex work, survival sex, sexual violence and HIV/AIDS prevention in Arumeru District, Arusha region Of Tanzania

Objective: To examine the knowledge and practices about HIV/AIDS among female Tanzanian commercial sex workers (CSWs) and assess the contextual dynamics that prevent safer sexual behaviours.

Method: The study used mixed methods and was implemented in two phases. Phase one assessed the knowledge and practices about HIV/AIDS among CSWs. Data were obtained with 54 CSWs, who were selected by using a snowball sampling approach. Semi-structured, face-to-face interviews with the CSWs were undertaken to allow the research participants to describe and discuss their lived realities as they perceive and experience them. In phase two, three discrete focus group discussions, each comprising 6-10 women, were carried out with 26 of the 54 CSWs who were interviewed in phase one.

Results: There was exploitation and inequity in the women's lives due to the multiple and overlapping oppressions of poverty and patriarchy. Sexual violence was framed, legitimised and reinforced by structural and cultural inequities. Such exploitation impacted not only on CSWs' lives as sex workers, but on their previous and/or simultaneous lives as mothers, wives, girlfriends and daughters. The women practised ‘survival sex’ as CSWs and/or sexual partners of men, and experienced sexual violence from their clients/partners. This violence was either culturally legitimised within a patriarchal framework or manifested itself as ‘displaced aggressive sex’ by men experiencing marginalisation in socio-economic spheres.

Separating the contributions of hearing, lexical knowledge and speech production to speech perception scores in children with hearing impairments.

Open-set word and sentence speech-perception test scores are commonly used as a measure of hearing abilities in children and adults using cochlear implants and/or hearing aids. These tests are usually presented auditorily with a verbal response. In the case of children, scores are typically lower and more variable than for adults with hearing impairments using similar devices. It is difficult to interpret children's speech-perception scores without considering the effects of lexical knowledge and speech-production abilities on their responses. This study postulated a simple mathematical model to describe the effects of hearing, lexical knowledge, and speech production on the perception test scores for monosyllabic words by children with impaired hearing. Thirty-three primary-school children with impaired hearing, fitted with hearing aids and/or cochlear implants, were evaluated using speech-perception, reading-aloud, speech-production, and language measures. These various measures were incorporated in the mathematical model, which revealed that performance in an open-set word-perception test in the auditory-alone mode is strongly dependent on residual hearing levels, lexical knowledge, and speech-production abilities. Further applications of the model provided an estimate of the effect of each component on the overall speech-perception score for each child.

Effectiveness of an HIV / AIDS prevention approach across three countries

The study examined the effectiveness of one community based HIV / AIDS prevention approach, Community Counselling, in PNG, India and Zambia. Results indicated the three countries differed along cultural dimensions. Differences on behaviour, attitude, knowledge and risk perceptions associated with HIV / AIDS were noted within each country that reflected exposure to the approach. The professional portfolio examines the curent situations in which cultural guidelines have been developed to assist clinicians in considering indigenous cultural differences in increasingly multicultural societies. Four case studies are presented in which aspects of these issues are identified and discussed.

How the concept of agency aids in teaching about sustainability

Sustainability education is becoming an integral part of education for all students.The paper revisits startling results from large scale international studies that show the dissonance between young people’s sustainability knowledge and the resistance of young people to put into practice. The reluctance to enact sustainability knowledge necessitates a review of current teaching practices as these raise important issues about current models of education and how sustainability is captured within education. Education about sustainability seeks to future proof our society through the teaching and learning of actions that ensure our collective long term future. For this reason teaching about sustainability incorporates a focus on social responsibility as well as individual responsibility.
