Reviews the provision of textbooks at all levels of the Nigerian educational system. Suggests that there is a great shortage of books at all levels of education, but the most acute being at the tertiary level due to an overwhelming dependence on imported books. Reveals that libraries promoting scholarship are limited to elite and private schools which are models which cannot be replicated on a national scale. Articulates the implications of the dearth of books for an informed citizenry and...

Conflicting models of the core-mantle boundary (CMB) structure have been derived from tomographic inversion of bulletin data: their long wavelength topography ranges from ±3 km to ±7 km according to the model considered. A simple test of these models is provided by the analysis of PKP(AB) phases observed at the antipode of a seismic region. Antipodal waves have the peculiarity that they arrive from a wide range of azimuths so that observations at a single station allow us to sample a large...

Hearing ability declines in the same manner for all people as they age. At least, that is what most people believe. This article examines the roles race and gender play in aging and declining hearing ability among African Americans and Euro‐Americans.

We studied physical fitness with the Harvard Step Test, growth, and appetite in primary school boys infected with hookworm (96% baseline prevalence), Trichuris trichiura (98% prevalence) and Ascaris lumbricoides (41% prevalence) who received a single 600-mg dose of albendazole or an identical placebo. Boys were examined, allocated at random within pairs by descending hookworm egg count to placebo (n = 26) or albendazole (n = 27) groups, treated, and re-examined 4 mo later. Four months after...

Abstract The coastal margins of Western Africa and most of the eastern Americas are considered to be stable continental interiors where large earthquakes occur infrequently. Since these regions have similar geologic and tectonic histories, it might seem reasonable to expect similarities between their large earthquakes. On the other hand, current plate forces acting on these regions differ and may lead to regional differences in earthquakes. To examine the similarities of coastal margin...

This study examines factors related to school achievement among low-income urban families in the Sudan. Data were obtained during January-February 1992 from a sample of 198 students aged 6-10 years from boys' and girls' schools in Ombada settlement in Khartoum, Elhag-Yousif in Khartoum North, and Arkwait in Khartoum. 53.5% of the sample were first enrolled in school after the age of 7 years. About 30% were enrolled prior to the age of 7 years. 4.5% had repeated a grade. About 25% had perfect...

The goal of this study was to determine if the hyporesponsiveness to beta-adrenoceptor stimulation observed in ovalbumin-sensitized tracheal smooth muscle is due to increased cholinergic muscarinic tone or to a defect in the beta-adrenergic cascade itself. We examined the effects of ovalbumin-sensitization on the responsiveness of guinea pig tracheae to agents that mediate relaxation at various steps in the beta-adrenergic cascade when the tracheal tissue was preconstricted with either...

The trends in drug use, expenditure and disease pattern at the University of Zimbabwe students' health facility over a period of five years (1987-1991), were analysed retrospectively. The study also analysed the use of the essential drugs concept and the drug situation in Zimbabwe. A total of 1,500 cases which were randomly selected were studied. The total student population over this period was 44,030. Data collection sheets where utilised to extract information from patients' cards....

Cognitive control therapy integrates psychodynamic principles and cognitive restructuring, addressing cognition and affect simultaneously. In pilot studies to evaluate the usefulness of cognitive control therapy for learning-disabled children and adolescents in the South African context, two experimental groups received therapy for a certain period of time while the two control groups did not receive therapy but continued with remedial programmes. Results of re-evaluation indicated improved...

As early as the last century, incipient education reform reports attacked the inadequacies of American education and called for a restructuring of schools. Much more recently, America 2000 called for a renaissance in education. Such reports, although well‐intentioned, have yet to address directly the needs of gifted students; they give gifted education little attention and allow it little influence in the education reform reports and movements. Nevertheless, these education reform movements...

There is a widening gap between the growing numbers ofAfrican Americans with HIVand AIDS and culturally specific programs that address education, prevention, and psychological services within the African American community. This article describes an Africentric model for training psychologists who deliver AIDS education, prevention, and services within the African American community. The principles of NTU and Nguzo Saba were used in the training of 75 African American psychologists with the...

This paper examines different models of science education and their relevance for the South African context. The authors draw on their extensive experience in other independent Southern African countries to examine case studies on the post‐independence development of science education in Botswana, Lesotho, Swaziland and Zimbabwe. The present problems in science education in South Africa are then analysed, and possible ways forward are suggested in the light of the case studies presented. The...
