A cohort of 120 medical stents who have nearly completed their medical training have been surveyed in Oran, Algeria. Most of them are not satisfied concerning their medical training (82%). However, they accept the conventional pattern of medical learning which allows little room to active participation from the trainees. The most appreciated scientific disciplines are cardiology for men and gynecology for women. In most cases, priority is given to clinical disciplines. Community medicine and...

Before the advent of the Acquired Immune Deficiency Syndrome (AIDS), many countries of the world transfused blood without seriously considering the potential risks of transmission of infectious agents. Even after it was shown that the Human Immunodeficiency virus(HIV) could be transmitted through blood and blood products, many hospitals and clinics in Nigeria still continue to transfuse unscreened blood. This study was therefore initiated to highlight the risks of transmitting infectious...

A new approach to the study of geometric relationships between tectonic structures and volcanic vents is presented. It is based on the mapping of tectonic and volcanic features using high-resolution imagery, including Synthetic Aperture Radar (SAR) images of the European Remote Sensing satellite number one (ERS-1). We have evidenced new faults: (1) N-striking normal faults in the Husavik fault zone of the North Atlantic ridge, and (2) NW-striking faults belonging to the Husavik transform...

Twenty-two apparently healthy Nigerian adolescent girls aged 11-17 years residing in a hostel, were studied over five consecutive days in order to assess their energy intake (EI), energy cost of specific activities and body composition (BC). The mean characteristics of the group were: height 1.58 (SD 0.1, range 1.42-1.68) m, body weight 49.1 (SD 7.9, range 34.0-61.0) kg and BMI 19.5 (SD 2.0, range 16.0-23.0) kg/m2. The food intake of each subject was assessed by direct weighing and its...

The Palaeoproterozoic Kedougou basement in the Mako area in eastern Senegal consists of four major rock complexes: 1) high-grade amphibolitic and gneissic rocks occuring as large xenoliths (the Sandikounda amphibolite-gneiss complex); 2) voluminous bimodal volcanic rocks (the Mako volcanic-plutonic complex); 3) the Sandikounda layered plutonic complex; and 4) trondhjemitic to calc-alkaline intrusive granitoids (the Laminia-Kaourou plutonic complex). Zircons from xenoliths of the Sandikounda...

The provision of sexuality education and contraceptive services to unmarried adolescents has became a key issue in the era of AIDS. International health organizations are promoting action worldwide. In Tanzania the Ministry of Health has started policy work, while the NGO sector is spearheading activities in the field. Yet there is a lot of public scepticism and resistance to launching such programmes, as many believe that these will promote promiscuity among the young. This article explores...

In situations where birth records are unavailable and stated ages are unreliable, the emergence of the permanent dentition can serve as an indicator of age. Due to substantial variation in the timing of tooth emergence, a sample (n = 721) of Zambian school children, with known ages, was examined to provide a tooth emergence reference standard for the area. Three methods for assigning ages were utilized and their accuracy assessed. A random test sample was withheld from the original study in...

LITHIUM salts remain one of the most widely used treatments for depressive illness. The mechanisms involved probably include reduction in free inositol. Visual perceptive disturbances can be a side effect of the treatment. We report here for the first time that chronic lithium treatment in the guinea pig induces a predominantly low frequency hearing loss and, in the longer term, loss of sensitivity is observed across the whole audiogram. The changes are reversed when treatment is arrested....

This paper highlights one of the central challenges facing the present South African government ‐ meeting the strong demands for increased and more equitable provisions of education and maintaining fiscal discipline. This task need not be daunting, as theory and evidence suggest that there is considerable scope for rationalising the existing state provision of social services in South Africa to make them more equitable and efficient. We employ an economic theory of clubs and argue that the...

Report of the workshopThis two-day workshop was convened with the twin aims of reviewing the state of water and climate research in Canada using isotope tracers and investigating the establish- ment of a revitalized "Canadian Network for Isotopes in Precipitation", as a contribution to the international GNIP program (Global Network for Isotopes in Precipitation), which is the well-known offspring of long-standing IAEA/Ii\MO efforts to document the distribu- tion of water isotopes in the global water ryde.

The purpose of this study was to explore self-reported stress experienced by secondary school teachers in Transkei, South Africa using a local unstandardized scale. Contrary to the literature on western teachers, an average rating of stress of 93.5 was reported by the 134 teachers, and no differences were noted between the 66 men and 68 women.

This paper identifies and explores three basic challenges which EFA 2000 poses to teacher education in Africa, viz: quality, quantity and relevance. Researched data is used to show the extent of the problems and to argue for some possible solutions suggested as to how teacher education in Africa could best prepare to meet these problems. There are many (even more fundamental) factors that will affect the quality, quantity and relevance of any education system. This paper focuses specifically...
