Over the last two decades, capacity-building in health research has been recognized as a priority by the international research community.Since 1987 the Joint Health Systems Research (HSR) Project for the Southern African Region has been making efforts to increase the national expertise for operational health research, starting in ten Southern African countries, in order to strengthen decision-making in health care at all levels.Initially, its targets were health managers and public health...

ABSTRACT South Africa has experienced a series of fundamental changes in its institutional structures over the past decade. The paper suggests that these changes underpin a “new” research environment for research students, the dynamics of which have not been commented upon in South African geographical debates. Drawing on research experiences of South African local government, the paper first considers the importance of political-temporal contingency in framing the research process,...

Abstract Zimbabwe's Belvedere Technical Teachers' College requires students to complete a Curriculum Depth Studies (CDS) project investigating some aspect of their teaching. The Professional Studies (PS) section at the college is undergoing an action research project to improve how students are prepared for and supported in doing their CDS projects. At the same time, the section is promoting action research as a model for the students' projects. By participating in the process that they are...

Abstract Time series of terrigenous source elements (Al, K, Ti, Zr) from core GeoB4901-8 recovered from the deep-sea fan of the Niger River record variations in riverine sediment discharge over the past 245,000 yr. Although the flux rates of all the elements depend on physical erosion, which is mainly controlled by the extent of vegetation coverage in central Africa, element/Al ratios reflect conditions for chemical weathering in the river basin. Maximum sediment input to the ocean occurs...

There is evidence of growing disparities in primary schooling rates between urban and rural areas in Tanzania. This paper presents empirical estimates for the determinants of primary school attendance in Tanzania for the early 1990s, and provides a comparison of attendance rates between the urban and rural areas for a number of different age groups. All the estimated models provide adequate fits to the data and many of the estimated coefficients are consistent with prior expectations. A...

This report describes the trends of substance use among youths by comparing data collected among senior secondary school students in Ilorin metropolis, Kwara State, Nigeria at 5-yearly intervals (1988-1998). In 1998, data were collected from 750 senior secondary school students from six secondary schools in the study area using a self-report 117-item questionnaire based on the World Health Organization (WHO) guidelines for student substance-use surveys. Substances investigated in the survey...

Splenic injuries are common and require emergency treatment. Efforts are now geared towards splenic conservation by way of splenorrhaphy. Thirty cases of splenic injuries seen at the University of Benin Teaching Hospital, Benin City, Nigeria between June 1992 and June 1997 were evaluated with a view to assessing the pattern of injuries and the management with respect particularly to splenic conservation. Males accounted for 66.6% of cases and the age range was 3-57 years (mean 20.8). Road...

The following paper, co-written by an American alumna of a U.S.- based study abroad program at the University of Ghana, Legon, and a U.S.-based American professor specializing in International and Black Atlantic Studies, will explore one particularly freighted instance of the end of such assumptions, by addressing the American student presence at the University of Ghana, Legon. Examination of the Legon case will, we hope, be valuable for all study abroad professionals, because the American...

Sexual activity among 534 Nigerian female secondary school students was studied using self-administered questionnaire. Prevalence of sexual intercourse was 25.7%. There was no significant difference between the junior (48.2%) and senior (51.8%) students (p > 0.05). Seventeen (12.4%) students had initiated sexual intercourse before 11 years. The frequency of sexual exposure was high, with 34.3% of the students having intercourse more than once in a week. Pregnancy rate among sexually active...

This paper presents evidence that returns to schooling in Libya are nonlinear. However, this evidence should not be taken as supporting the sheepskin effect. Although high-school graduation is associated with higher earnings over and above what is predicted by the linear model, other diploma years do not possess the same advantage when a spline function is used.When a step function is used, various years, some of which do not lead to a diploma, show high marginal returns.
