Leadership support has been identified as an essential component of successful workplace health promotion (WHP) programs. However, there is little research in this area and even less theoretical conceptualization on ways in which leadership support for WHP is related to improved employee wellbeing. In this paper, we developed and tested a model of leadership support for WHP and employee wellbeing outcomes using employer and employee data gathered from 71 South African organizations. A theoretical model based on social exchange theory was developed. It was hypothesized that perceptions of company commitment to health promotion mediates the relationship between leadership support, the provision of WHP facilities and employee wellbeing. A hierarchical structural equation modeling technique was used to test the model. We determined that leaders' support for WHP was important insofar as they also provided health promotion facilities to their employees. No direct relationship was found between leadership support alone and employee wellbeing.

This paper discusses the application of an information, motivation and behavioural skills (IMB) model in a school-based programme for the reduction of HIV risk behaviour among 259 Grade 11 learners in two high schools in Alexandra township, Johannesburg. School 1 was the Experimental group, while School 2 was the Control group. After a baseline study (Time 1) at both schools, a 3-week intervention programme was conducted at School 1. A post-test (Time 2) was conducted at both schools. The intervention was repeated at School 2, followed by another post-test (Time 3) at both schools. A final test (Time 4) was conducted at both schools. While there were positive changes in the levels of HIV&AIDS IMB in learner participants, these changes may not be entirely attributed to the intervention. If an IMB model-based intervention is to be maximally effective in reducing HIV-risk behaviour among adolescents, it must focus on the behavioural, structural and socio-cultural contexts in which adolescents live. Keywords: IMB model, vulnerability, adolescents, risk behaviour, structural, socio-cultural Résumé Cet article traite de l'application du model : Information, Motivation et Comportement (IMC) dans un programme en milieu scolaire pour la réduction des comportements à risque relatif au VIH parmi 259 élèves de l'avant dernière année du secondaire dans deux écoles secondaires du canton d'Alexandra, à Johannesburg. L'école 1 était le groupe expérimental, tandis que l'école 2 était le groupe de contrôle. Après une étude de base (Temps 1) dans les deux écoles, un programme d'intervention de 3 semaines a été mené à l'école 1. Un post-test (Temps 2) a été mené dans ces deux écoles. L'intervention a été répétée à l'école 2, suivi par un autre post test (temps 3) dans les deux écoles. Un test final (temps 4) a été mené dans ces deux écoles. Bien qu'il y ait eu des changements positifs dans les taux d'information, de motivation et des compétences comportementales relatifs au VIH / SIDA chez les élèves participants, ces changements peuvent ne pas être entièrement attribué à l'intervention. Si une intervention du type IMC doit atteindre une efficacité maximale dans la réduction des comportements à risque chez les adolescents, elle doit se concentrer sur les contextes comportementaux, structurels et socioculturels dans lequel vivent les adolescents.

The purpose of this epidemiological study was to investigate the long-term effects of exposure to aircraft noise on reading comprehension on a sample of South African children. Given the impairment of reading comprehension found within the noised-exposed group before the relocation of the airport, it was the intention of this study to determine whether the effects of aircraft noise on reading comprehension remained after the relocation of the airport or whether they disappeared. A cohort of 732 learners with a mean age of 11.1 years participated at baseline measurements in 2009 and 650 (mean age=12.3) and 178 (mean age=13.1) learners were reassessed after the relocation of the airport in 2010 and 2011, respectively. The results revealed no significant effect of the groups on reading comprehension across the testing periods, but significant effects of home language were demonstrated on reading comprehension. These findings suggest that exposure to chronic aircraft noise may have a lasting impact on children's reading comprehension functioning.

The present study examined the relationship between inter-role conflict and life satisfaction in a sample of working mothers. It also explored Sense of Coherence as a moderating variable in the relationship. Given the exploratory nature of the study, a cross-sectional, correlational design was adopted. Self-report data were collected from 40 working mothers from the northern suburbs of Johannesburg. Statistical analysis found that there was a significant inverse relationship between inter-role conflict and life satisfaction. Sense of Coherence was found to be a significant moderator of the inter-role conflict and life satisfaction relationship. Theoretical and practical implications are discussed in terms of the findings.
