South Africa's single electricity-generating utility ESKOM is considered to be the powerhouse of Africa. Proper industrial and residential demand-side management (DSM) of electricity usage could improve efficiency and contribute significantly to releasing spare generating capacity. South African tertiary education institutions have started energy-saving activities (the AfriCampus Collaboration) and work on energy conservation on their campuses. The various projects in the...

Due to lack of national cancer registry, the pattern and outcome of gastrointestinal tract (GIT) cancer is unknown in Ethiopia. In the period 1992-1996, a prospective study was carried out in 534 patients with GIT malignant tumours admitted to the Tikur Anbessa Hospital Department of Surgery, Addis Ababa. Relevant data were recorded on a prepared proforma for specific disease. Of these, 437 cases (82%), 142 oesophageal, 68 pancereato-biliary, 96 gastric, and 131 lower GIT cancers have been...

In this study of 62 African American families living in poverty, we examined the main and interactive effects of psychological, family, and school factors on students' grade point average across the middle school transition. Both parent interviews and student surveys were collected, resulting in three major findings. First, students experienced a significant decline in grade point average across the transition from elementary to middle school. Second, students who felt more academically...

In a cross-sectional survey undertaken in 22 communities of 6 districts in the South Gondar Zone of the Amhara National Regional State, 2279 school children had their stools examined for schistosomiasis mansoni and soil-transmitted helminths using the Kato-Katz technique. Overall the prevalence rates were 16.4%, 28.9%, 9.5% and 12.9% for S. mansoni, A. lumbricoides, T. trichiura and the hookworms, respectively. S. mansoni infection was registered from 14 of the 22 communities, in more than...

This paper addresses the general question of why teachers teach in the way they do. Data collected from Egyptian science teachers both in the UK during an in-service course and on their return to Egypt are reported. The teachers' evaluation of which in-service experiences they thought of most use is contrasted with the changes they were able to bring about in their own teaching on return to Egypt. Follow-up interviews and classroom observations in Egypt showed the teachers to be frustrated...

Abstract Abstract An investigation of hydrological droughts has been conducted, based on the truncation level approach: each drought event is characterized by its duration and deficit volume. The truncation level is defined to reflect the expected natural water availability and, therefore, is evaluated monthly as a fixed percentile of the monthly flow-duration curve. Thus, the problem of expected zero flow of ephemeral rivers during the dry season is taken care of. The data material consists...

Caerphilly Cheese making procedure was modified to suit the conditions and kitchen environment of the average Cameroonian household. Cheese making trials were carried out for over a period of twelve months. Results show that the ripening time for milk increased from 45 minutes to 60 minutes; curd formation time from 45-60 minutes to 60 - 90 minutes, scalding temperatures, method of draining, salting, pressing and maturation temperature have been modified (Fig.1). The acid development pattern...

Currently, emergency contraception is seldom used in Kenya. As part of a larger study designed to provide insight into the possible roles for the method in Kenya, we assessed the knowledge of and attitudes towards emergency contraception in two groups of potential users, and we focus on these data specifically in this paper. We interviewed clustered samples of clients at ten family planning clinics in Nairobi (n = 282) and conducted four focus group discussions with students at two...

The University of the Witwatersrand School of Social Work in South Africa did not teach social policy training during the years of apartheid, and although social policy is integrated into some courses, there still are no social policy training courses being offered. This article discusses the importance and need for social policy to be integrated into the curriculum as a core course. Implications for students and the country as a whole are discussed.

The role of education in development is widely recognized in many countries. However, the value placed on formal education differs from one community to the next. In this paper I argue that among the Borana pastoralists of Marsabit District, Kenya, the value of formal education is based on wage-labor opportunities. High value placed on women's household labor and low accessibility to non-household employment places differential pres- sure on the education of Borana children. This leads to a...

Thirteen cases of advanced abdominal pregnancy (AAP) managed at the Komfo Anokye Teaching Hospital (KATH), Kumasi, Ghana, over a two-year period (1993-1994) are presented. An incidence ratio of one advanced abdominal pregnancy to 1,320 deliveries occurred during this period. The ratio of advanced abdominal pregnancy to ectopic pregnancy was 1:43.7. The perinatal mortality rate and maternal case fatality rates were 69.6% and 15.3% respectively. Recurrent abdominal pains in the gravid patient...

Research on the institutional choice of ethnic minority graduate students flourished in the 1990s, however, such studies tended to combine master's and doctoral students with no delineation between the two. Utilizing a national random sample, this study identifies factors that influence African American students' decisions to apply to and attend doctoral programs in higher education administration. Results indicate that respondents are influenced by academic quality, academic infrastructure,...
