ABSTRACT The attainment of sustainable food security in sub-Saharan Africa requires the efforts of a large cadre of well-trained agricultural resource specialists familiar with the constraints and perspectives of smallhold farmers and experienced in interdisciplinary problem-solving. The Forum for Agricultural Resource Husbandry (FORUM) was initiated in 1992 by The Rockefeller Foundation to stabilize Faculties of Agriculture in Kenya, Malawi, Mozambique, Uganda and Zimbabwe by providing...

The analysis was based on the 1994 Zimbabwe Demographic and Health Survey combined with aggregate data from the 1992 census. Discrete-time hazard models for first and higher-order births were estimated for 1990-94. The average length of education in the district and the proportion who are literate were found to have no impact on a woman's birth rate above and beyond that of her own education, when it was controlled for urbanization. This was the case for women who themselves had little or no...

Deformation throughout Afar over the past 2 myr has been characterized by widespread and intense crustal fragmentation that results from inhomogeneous extension across the region. In eastern Afar, this situation has evolved to localized extension associated with the westward propagation of the Gulf of Aden/Gulf of Tadjurah seafloor spreading system into the Asal–Ghoubbet Rift. During the gradual process of rift propagation and localization, crustal blocks in eastern Afar sustained clockwise...

Abstract The purpose of this study is to fill a gap related to the limited number of multicultural studies related to African immigrants in the U.S. and their educational issues. This study will a) analyze the emotional, linguistic and cultural issues facing new immigrants from Africa attending American schools, and b) provide strategies that teachers can use to develop effective intercultural communication with their students and their parents from Africa.

An account is given of how a national diabetes care and education programme was developed in Ghana, a developing country, through international collaboration of medical schools, industry and government health care institutions. The approach is by way of trained diabetes teams consisting of physicians, dietitians and nurse educators at two tertiary institutional levels (teaching hospitals) who in turn trained teams consisting of physicians, dietitians or diettherapy nurses, nurse educators...

Abstract Central to South Africa's democratic transformation have been attempts to understand how and why human rights abuses were common under apartheid. In testimony to the Truth and Reconciliation Commission evidence has emerged of a wide range of past complicity in human rights abuses by health professionals and their organisations. This has presented a major challenge to the health sector to develop ways to operationalise a commitment to human rights in the future. This paper argues...

To determine whether educating community leaders about epilepsy would lead to an increase in epilepsy cases being diagnosed and treated at primary health centers.This was a single-arm cohort study performed in Epworth, a periurban township outside Harare, Zimbabwe. The subjects were Epworth community leaders (Local Board members, teachers, nurses, police officers, traditional healers, prophets). Educational workshops were given on epilepsy, its cause, and its management, and the number of...

Abstract This research extends and revises research on the association between the racial composition of schools and academic achievement. Some earlier studies have looked at how the concentration of minority students was related to test performance of both Black and White students, and have found a negative correlation for both groups that could not be attributed to socioeconomic factors. Using hierarchical linear modeling and including individual-level and school-level family structure...

This study identifies theoretically based predictors of condom use in a sample of 253 sexually active African-American college students recruited from two historically African-American colleges. The Information-Motivation-Behavioral (IMB) skills model of AIDS-preventive behavior was employed to delineate the roles of HIV/AIDS knowledge, experiences with and attitudes toward condom use, peer influences, perceived vulnerability, monogamy, and behavioral skills. A predictive structural equation...

This study is based on the premises that information technologies (IT) are essential to African development and that education systems are responsible for developing a countries' human capacity to maximize those technologies. The study examines the ability of education systems in Mali and Ghana to develop the capacity to harness the potential of information technologies for African-empowered development. The condition of education and telecommunications in each country is examined in light...

Teratomas are rare in amphibians and the neoplasm described here, which had a significant thyroid carcinoma component, is the first tumour of this type to be reported in Xenopus laevis. The thyroid component contained moderately to well-differentiated acinar glands showing much hyperplasia, dysplasia, and reduced and distorted colloid reservoirs. Cartilaginous, neural, muscular, mesenchymal and gut-like epithelial components were also observed in this ventral mediastinal neoplasm, indicating...

A Time Domain Electromagnetic (TDEM) survey was carried out in and around the caldera of the Fogo volcano, Cape Verde Islands, to detect the low resistive structures that could be related to groundwater. A sign reversal in the sounding curves was encountered in central-loop measurements for the soundings located in the centre of the caldera along three main radial profiles. The negative transients are recorded in the early channels between 6.8 and 37 μs. Negative values in an early time...

The concentration of zinc and copper in 180 grass and associated soil samples collected in triplicate samples were determined. The triplicate field data were averaged to yield mean soil and vegetation metal concentrations at each sample location. The zinc levels ranged from 7.0 ± 1.4(S.D.) — 134.8 ± 6.3(S.D.) μgg‐1, dry weight, in grass and from 0.6 ± 0.2 (S.D.) — 119.5 ± 3.9 (S.D.) μgg‐1, dry weight, in surface soils. The results showed that zinc contents are high close to the road traffic...

This paper compares the species composition of free swimming schools and schools associated with fish aggregating devices (or FADs) observed by scientists in the eastern equatorial Atlantic during the early eighties and late nineties. This comparison shows that in free swimming schools, big changes in the species composition have occurred. The main change is a rarefaction of mixed species free schools (skipjack and small yellowfin or bigeye). This change is probably a real biological one,...

This paper reports on a two-month study of the information literacy of 26 grade seven teachers within a circuit of 17 primary schools in Cape Town (South Africa), comprising three historically advantaged schools situated in a historically white suburb and 14 disadvantaged schools in adjacent historically black townships. The focus of the study is project work, which an earlier ethnographic field study confirmed to be a useful window through which to view teachers' information literacy....

We are grateful for the opportunity to re-analyze our data as suggested by Kinsman et al. and we apologize if the P values quoted in our paper appear to claim unwarranted precision. A paired t-test approach weighting the mean % scores proportionately to the differing numbers of students involved gave the following results. As expected this analysis gives results that have a higher P value than in the original analysis. The differences between changes in knowledge scores become of borderline...

No satisfactory strategy for reducing high child mortality from malaria has yet been established in tropical Africa. We compared the effect on under-5 mortality of teaching mothers to promptly provide antimalarials to their sick children at home, with the present community health worker approach.Of 37 tabias (cluster of villages) in two districts with hyperendemic to holoendemic malaria, tabias reported to have the highest malaria morbidity were selected. A census was done which included a...

In the article by Harvey et al. the evaluation procedure of the drama-based AIDS education intervention conducted in KwaZulu Natal South Africa was described. It is noted that the programs evaluation took the form of a randomized community intervention trial using seven schools each in the intervention and control groups. Overall Harvey et al. point out that there is a dearth in the literature of evaluated AIDS education programs in Africa. Although this paper from KwaZulu Natal contributes...
