ABSTRACT The amount of nitrogen lost through leaching is not known for a wide range of agrosystems of the Tropics. This study was conducted to determine the effect of past erosion on leaching losses of N from a Mollic Andosol at Lyamungu Research Institute, Kilimanjaro region, Tanzania. Lysimeters, 80 cm in diameter and 89 cm deep, were established in August 1994 on a soil with different severity of past erosion. The climate is humid with the most rain falling in April-May. Soil erosion...

Change is a fact of life. In most parts of Africa food security is still a critical issue and therefore food production will continue to be a major focus of universities and other agricultural education institutions for some time to come. The delivery of quality education and training is, as we have seen, a major challenge in view of decreased funding, higher student intakes, decreasing levels of funding, and loss of key experienced teaching and research staff. However, it is important to be...

Abstract Antebellum African‐American literary societies in Philadelphia promoted rhetorical education and gave members the opportunity to craft powerful arguments. This study investigates the presence of the Anglo‐American rhetorical tradition—particularly eighteenth‐century Scots principles of Blair, Smith, and Campbell—in six representative speeches delivered at literary society meetings. Our analysis focuses on two major issues: 1) the influence of traditional principles of...

The recent experiment in bilingual education in Mozambique known as PEBIMO, which utilised two different Bantu languages in transitional programmes for lower primary schooling, offered an alternative to exclusive instruction in Portuguese, which is a foreign language for approximately 98 percent of Mozambicans. Evaluations done during the final two years of the experiment using both quantitative and qualitative means demonstrate that students benefited greatly from use of the mother tongue...

We assessed whether a 1-year teaching programme in northern Zanzibar would improve prescribing practice. Data on polypharmacy and appropriateness of the treatment of upper-respiratory infection, anaemia, and scabies from the 17 primary health-care units in northern Zanzibar were analysed before and after the teaching programme. There was a significant and sustained reduction in polypharmacy and an improvement in the treatment of upper-respiratory infection, scabies, and anaemia. This...

To assess the independent and joint effects of the components of the metabolic syndrome, including leptin, which is a recently proposed addition to this syndrome, in predicting the cumulative incidence of impaired glucose tolerance (IGT) and diabetes among individuals with normal glucose tolerance.This prospective study involved 2,605 residents of Mauritius with normal glucose tolerance who were followed for 5 years for IGT or diabetes onset in relation to total and regional adiposity (BMI,...

In this study, 160 African American seventh grade students were asked to complete a questionnaire designed to measure variables such as, `racial preference of teacher', and their perception of the types of treatment received from their Caucasian teachers. The majority of the students, contrary to some research, believed their teachers treated them fairly, related to them, and did not use race as an excuse to mistreat them or punish them for bad behavior. However, a slight majority stated...

This article reports the results of a 1-year evaluation of the CoZi model, a whole school reform model that combines Edward Zigler’s School of the 21st Century (which includes on-site, daylong, and year-round preschool, after-school care, and family support services) with James Comer’s School Development Program, a school management and collaborative decision-making model. The study used written surveys, in-depth interviews, achievement tests, and classroom observations to study teacher,...

Acute and chronic respiratory diseases, which are causally linked to exposure to indoor air pollution in developing countries, are the leading cause of global morbidity and mortality. Efforts to develop effective intervention strategies and detailed quantification of the exposure-response relationship for indoor particulate matter require accurate estimates of exposure. We used continuous monitoring of indoor air pollution and individual time-activity budget data to construct detailed...

In Namibia in 1990, apartheid was ended, and a democratic form of government was installed; 2 years later, the national government established a system of partially decentralized regional governments. At the same time, the government reacted to the severe drought of 1992 by instituting a national drought relief bureaucracy with particular attention to the predominantly Black African communal areas, which incorporated the new regional councils. This, in turn, created the opportunity for those...

A data-intensive research project on the climate history of Africa has been made part of an introductory college-level earth-science course. The project introduces students to the challenge of working with real data as student teams analyze and interpret extended records of monthly rainfall and average temperature for stations across Africa with the goal of defining regional climate patterns and assessing evidence regarding climate change. The exercise emphasizes quantitative skills in data...

The Thousand Schools Project was conceived at a time of far-reaching social and political change in South Africa. The innovative features of the programme are acknowledged. Drawing on evidence derived from an evaluation of the implementation phase of the project in the province of KwaZulu-Natal, critical issues are identified in relation to the project's goals and strategies, and in relation to the impact of contextual factors. The paper then examines the implications of these issues for an...
