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...

In this article, an overview of economical, educational, and health care conditions in Ghana are discussed. The foundation for an educational course in regional anesthesia is laid, steps are taken for development and implementation is identified. Benefits of the experience to the people of Ghana are identified and personal rewards highlighted.

The United Nations' Special Initiative for Africa (UNSIA) focuses on selected low- enrollment African countries in an effort to help them find pragmatic, sustainable solutions to the problems that have depressed primary school enrollments for so long. As part of this process, a four-country study was conducted between November 1998 and May 1999 in Burkina Faso, Guinea, Mali, and Mauritania. The study specially focused on identifying and understanding the practices likely to promote female...

The prevalence of intestinal parasites and their relations to anaemia and nutritional status among school children aged 6-11 years in Gaza was studied. The target area is overcrowded with improper sewage disposal system and low socioeconomic levels. Anaemia was assessed by haemoglobin level (Hb) and nutritional status by anthropometric measurements including weight for age (WA), weight for height (WH) and height for age (HA). Intestinal parasites were found to be prevalent in Gaza. The...

The present study explored reported awareness of AIDS among third-year majors in education. The 71 men and 93 women had a mean age of 24.7 yr. (SD = 4.7 yr.). Those who were aware outnumbered those who were not.

To determine the prevalence of vitamin A in pre-school children in Kenya.Cross-sectional survey.Fourteen districts randomly selected from the eight provinces in Kenya.Six thousand four hundred and twenty five pre-school children (3298 boys and 3127 girls) aged 6-72 months in 27 clusters randomly selected from fourteen districts.Serum retinol levels and xerophthalmia were determined using High Pressure Liquid Chromatography (HPLC) and ophthalmological assessment respectively.The mean serum...

We tested 758 fecal Escherichia coli isolates, recovered from Nigerian students in 1986, 1988, 1990, 1994, and 1998, for susceptibility to seven antimicrobial drugs. The prevalences of strains resistant to tetracycline, ampicillin, chloramphenicol, and streptomycin were 9% to 35% in 1986 and 56% to 100% in 1998. These findings demonstrate that resistance gene reservoirs are increasing in healthy persons.

This paper examines the nature of students’ conflicts in tertiary institutions in Nigeria and observes that the prevalence of such conflicts has been due to their mismanagement which is traceable to a conventional, but faulty and often monolithic diagnostic of the problem. The paper, therefore, takes a sociological approach to the analysis of the crisis. The major argument is that overt students’ conflicts are rather social manifestations of more deep rooted conflicts underscored by...
