Several approaches to teaching practice are possible. Much current discussions on the ways and means of improving teacher education is focused on this practical element of teacher preparation. (Stones and Morris, 1972). Some approaches to teaching practice will be examined in this paper. The meaning, impact on colleges of education and schools, merits and demerits and the feasibility for Zimbabwe of these approaches to teaching practice will be examined. It is hoped that the paper will...

Carbon and O isotopic compositions were determined for calcite and siderite from the Buru and Kuge carbonatite centres. Wide ranges in the isotopic compositions of these minerals were observed with values of δ13C and δ18O for the Buru calcites ranging from +1.3 to −3.2% (PDB) and + 11.3 to +26.2% (SMOW), respectively. The δ13C and δ18O ranges for the Kuge calcites are −3.1 to −8.4% (PDB) and +18.1 to + 25.7% (SMOW). The Buru siderites plot in a narrow and restricted range at −3.1 to −4.4%...

This paper proposes a causal model of sexual activity among a randomly selected sample of 305 Junior secondary school girls in Zambia. The results indicate that liberal sexual attitudes influence romantic involvement with boys. Emotional involvement is likely to result in sexual activity. Traditional courtship forms are slowly being replaced by modern patterns of courtship behaviour. Policy and programme implications are discussed.

Will early detection impact on stage of disease and recurrence of prostate cancer in a high risk population? We initiated a community based study to educate and recruit African American men for early diagnosis of prostate cancer, that is the Detroit Education and Early Detection (DEED) study. Our objective was to evaluate our recruitment process for this target population, examine the percentage of organ confined prostate cancer in men undergoing radical prostatectomy and measure recurrence...

The aim of this study was to determine whether serum leptin concentrations are reduced in response to short-term energy restriction in centrally obese individuals with impaired glucose tolerance or non-insulin-dependent diabetes mellitus. Twenty African Americans [16 females and 4 males, 44 +/- 7 y (x +/- SD), 107.2 +/- 23.8 kg, 39 +/- 7% body fat] consumed a 7-d energy-restricted diet (4.03 +/- 0.72 MJ/d) of whole foods. Oral-glucose-tolerance tests (OGTTs) were performed before and...

This paper examines the issue of community ownership with reference to an adult literacy and basic education programme in NW Zaire. After a discussion of community ownership, stressing the need for local control and relevance to local needs, it outlines the context and development of the programme in NW Zaïre and considers the degree to which ownership is manifested in the design of technical aspects of the programme and its structures. Finally it identifies some key issues for continued...

This is a contribution and critique of the debate initiated by Dzvimbo's (1991) article on the nature of knowledge and discourse practices in Zimbabwe's teacher training colleges (Zimbabwe Bulletin of Teacher Education, Volume 1, Issue 1). Dzvimbo's paper is important in that it underscores the importance of teacher education to educational and social reform. That teacher education is significant is obviated by the fact that in many countries in the Third World, schools, classrooms and...

AIDS-related knowledge and behaviours among students at the Gondar College of Medical Sciences, Gondar, Ethiopia were evaluated based on identical surveys conducted in 1990 and 1992. One hundred three second year students provided information in 1992. Analysis indicated that 49% were engaged in sexual intercourse and only a third of these group used condom despite their improved knowledge and belief on condom compared to their previous position in 1990 (p < 0.004). On the other hand, their...

The recently signed Comprehensive Test Ban Treaty provides for an international network of primary and auxiliary seismic monitoring stations (IMS) to verify its compliance. Calibration is required to confidently use these stations to identify and discriminate between earthquakes, mine-related events and clandestine nuclear explosions, particularly for small to moderate seismic events recorded regionally at only a few stations. Given the lack of regional recordings of underground nuclear...

A comparison of two studies performed in Sierra Leone on the effect of anthelmintic, chemotherapy, levamisole, albendazole or a placebo in children aged 6 to 10 years on the prevalence and intensity of common soil transmitted helminths (S-THs) infections is presented. In total 501 children were screened, and 394 successfully follow-up. At baseline their overall prevalence and intensity (epg) of Ascaris, Necator and Trichuris were 34% (2,877), 22% (284) and 39% (266) respectively. At baseline...

The adoption of Western lifestyles is known to lead to increasing prevalence of non-insulin-dependent diabetes mellitus in Africa, yet epidemiological studies using standardised methods are rare. The prevalence of diabetes and impaired glucose tolerance was determined in a rural and an urban community in Cameroon using the 75-g oral glucose tolerance test and the World Health Organization diagnostic criteria in 719 rural (292 men, 427 women) and 1048 urban (458 men, 590 women) subjects aged...

This study encompasses a needs analysis of life-skills in 1992, first-year full time students at the Vaal Triangle Technikon, Vanderbijlpark. To evaluate the hypotheses, respondents who completed the self-assessment Life Skills and Competencies: General Questionnaire on Life Competencies and Skills, were divided into language groups (Afrikaans, English, African). Data indicates differences between the needs of the language groups themselves and between male and female respondents. A...

A short term, baseline study was undertaken to determine the occurrence and levels of microbial pollution in three major rivers in Ghana- the Birim river, Kakum river and the Nakwa river. Routine bacteriological examinations were made to determine the levels of total coliforms (TC), faecal coliforms (FC) and faecal streptococci (FS). Results obtained showed that TC, FC and FS counts were high in all the three rivers thus making them unsafe to drink untreated water from those sources. Eight...
