The paper aims to contribute to the understanding of why there is a lack of domestic saving and investment in rural parts of sub-Saharan Africa. It focuses on heterogeneity in inter-temporal preferences as a possible explanation of this important puzzle. The study is based on a unique experimental data set collected from 856 respondents in Ugandan villages and scrutinizes how individual patience – measured by the discount rate – is formed. The results suggest that Ugandan respondents are...

Despite current legislation which makes provision for collaboration between the public school sector and home schooling, it appears that much can still be done to move towards a closer partnership. Consequently I investigated the possibilities of such a liaison. A literature review on the nature of home schooling in general was conducted as background to a qualitative investigation on the views of parents, educators and other role players of home schooling within the South African context....

Internationally it has become recognised that diffuse source water pollution from mining activities severely affects the degradation of water quality especially with regards to acidification and metal loading. South Africa is facing major problems with regard to the management and treatment of contaminated mine water. Very little has been published for South Africa about the quantities and qualities of diffuse source water pollution by the mining industry. Furthermore the available...

Background.African hospitals have experienced major increases in admissions for tuberculosis, but they are ill-equipped to prevent institutional transmission. We compared institutional rates and community rates of tuberculin skin test (TST) conversion in Harare, Zimbabwe Methods.We conducted a cohort study of TST conversion 6, 12, and 18 months into training among 159 nursing and 195 polytechnic school students in Harare. Students had negative TST results (induration diameter, ≤9 mm) with...

Several studies have reported a higher prevalence of infection for human fascioliasis among girls than among boys. To investigate this aspect further a sufficiently large data set was assembled comprising of 21 477 subjects with 932 positive cases. Subjects were primary school children covered by a control programme implemented by the Egyptian Ministry of Health and Population in the Nile Delta from 1988 to 2002. Stool analyses were performed by the Kato–Katz thick smear technique for a...

Students were identified by their teachers as having behavior problems. Participants were 44 students and 25 teachers from two suburban and three urban elementary schools in a mid-western state. A multi-rater, multi-method approach was used. As teacher-reports of...

Achieving cultural competence in the care of a patient who is a member of an ethnic or racial minority is a multifaceted project involving specific cultural knowledge as well as more general skills and attitude adjustments to advance cross-cultural communication in the clinical encounter. Using the important example of the African American patient, the authors examine relevant historical and cultural information as it relates to providing culturally competent health care. The authors...

This study compared the predictive value of the theory of planned behavior in university students in South Africa (N = 251) and the United States (N = 160) who completed an anonymous self-administered questionnaire. Multiple regression analyses revealed that condom use and intention were significantly predicted by positive condom attitude, subjective norm, self-efficacy, and attending university in South Africa. Significant interactions between country and predictors indicated that...

This paper critiques the approach taken by the Ghanaian Government to address mercury pollution in the artisanal and small-scale gold mining sector. Unmonitored releases of mercury—used in the gold-amalgamation process—have caused numerous environmental complications throughout rural Ghana. Certain policy, technological and educational initiatives taken to address the mounting problem, however, have proved marginally effective at best, having been designed and implemented without careful...

Although there is a growing body of literature on students' transition from middle school to high school, much of the literature fails to take into consideration the distinctive racial and environmental circumstances of African American students. This article reviews literature related to the transitioning of African American students and discusses the unique challenges that African American students experience during adolescence. Counseling interventions are delineated and implications for...
