Using the cultural and human ecology models as a guide, African-American fathers' involvement with infants as a function of whether their wife worked full-time or part-time, and the association between father involvement and fathers' functional styles within the family, family support, income, and education were examined. Fathers were less likely to engage in and devote time to basic caregiving activities than were mothers. Paternal investment in childcare did not differ as a function of...

Summary The strong influence of climate upon the distribution and utilization of Africa's natural resources occurs through both its mean state and through its temporal variability. The latter aspect has received increasing attention. The prospect of future global-mean warming due to greenhouse gas emissions adds a further dimension to the problem. Correct analysis and interpretation of climate variability over Africa, and its linkages with the global climate system, are important if...

A study examined the factors determining the learning environments of agricultural science classes in Nigeria and the effects of those learning environments on student attitudes and achievement. The study sample, which was selected to be representative of schools from Nigeria's northern and southern regions and urban and rural areas, consisted of 1,175 students in 50 secondary-level agricultural science classes in 20 different schools located in 8 states. The Constructivist Learning...

The Special Science Programme was introduced into the Alvan Ikoku College of Education, Owerri, Nigeria, on account of the finding that students desiring to pursue Mathematics as an area of speciality in addition to associated physical or social science disciplines, in the Nigerian Certificate of Education programme, lacked one of the requisite entry qualifications in most cases ‐‐ that is a credit level pass in Mathematics in the West African School Certificate (WASC) examinations. It thus...

This article compares household income level and pre‐schooler weight‐for‐age across household groupings that are differentiated by female headship variables which are reflective of the heterogeneity of female‐headed households. Data from Kenya indicate that it is the interaction of income and female headship at low‐income levels which promotes pre‐schooler nutritional status. For Ghana, incomes have to be quite large (in the upper tercile of the distribution) before a reduction in the...

This paper examines sensitivity of the Southern African subcontinent to climate change. It shows that the region has particularly sensitive water resources. Aridification of the subcontinent will affect a wide range of ecological processes, due to possible loss of important wetland habitats, reduced stream discharges as well as reduction in extent of shallow lakes. The primary response of terrestrial ecosystems will be a reduction in diversity as sub-humid biomes are replaced by more xeric...

Fecal specimens were obtained on 3 occasions at 10-12 wk intervals from 315 children in 3 rural villages in Zimbabwe and from 351 children in the high-density suburbs of an adjacent small town. Specimens were examined qualitatively and quantitatively for eggs of Hymenolepis nana, and these were found in 142 (21%) children. Infections occurred more frequently in younger children in the urban area but in older children in rural areas. The prevalence in urban areas (24%) was higher than in...

The Perceived Teacher Behavior Inventory was designed to measure three dimensions of students' perceptions of the behaviors of their teachers. This research was conducted to assess the statistical validity and reliability of the instrument administered to 770 students attending two coeducational high schools in Cape Town, South Africa. Factor analysis clearly identified three subscales indicating that the instrument distinguished the students' perceptions of their teachers' behaviors in...

Perceptions of the normal or no-problem use of alcohol held by male and female high school students were investigated. A sample of 127 male and 113 female high school students were asked to indicate their perceptions of the normal use of alcohol for their own sex and the opposite sex using a structured questionnaire. The students were also asked to select from a list of reasons those reasons they considered were non-problem reasons for using alcohol. Male and female students set levels of...

The Mio-Pliocene Tchabal Nganha volcano in the Adamawa Plateau (Cameroon) contains a broad range of rock types from ankaramites to phonolites and trachytes. Tchabal Nganha is located on large N70°E strike-slip faults that have been active since the Cretaceous and delimit the Adamawa Plateau horst. Geological mapping revealed a succession of basaltic-hawaiitic lava flow units, mugearite-benmoreite breccias, phonolite and trachyte lava flows and plugs, and finally tiny basaltic and...

One thousand and forty one Senior secondary School Students in Ilorin, Kwara State, Nigeria were surveyed using a 117-items self-administered substance use questionnaire in May 1988. Males constituted 56.6% and Females 43.5% of the study population. The mean age was 16.8 years (S.D. 1.84). The most currently used substances were found to include salicylate analgesics (56.2%), antibiotics (23.6%), stimulants (21.6%), alcohol (12.0%) and cigarette (4.4%). Current use of alcohol, antibiotics...

The paper analyzes the performance of adjusting and non-adjusting countries in sub-Saharan Africa and Latin America between 1980 and 1988. The analysis documents that the 1980s were a decade of growing austerity in Latin America and sub-Saharan Africa, which reduced the potential contributions of households to education. Adjusting countries also reduced public education expenditures. Facing reductions in funds, education Ministries cut disproportionately the share for teaching materials....

In 914 consecutive medical admissions to Komfo Anokye Teaching Hospital, the prevalence of infection with Human Immunodeficiency Virus type I (HIV-I) and Human Immunodeficiency Virus type 2 (HIV-2) was 12.6%. The prevalence in females was twice that found in males. The infection rate was maximum in the age group 25-29 years for females (45%) and 30-34 years for males (29%). There were 7 cases infected with HIV-2 alone, 55 cases infected with HIV-I alone and 53 cases with dual infection. The...

Two studies are reported which explore the approach to learning of Nigerian secondary school pupils from both emic and etic perspectives. In the first study, 150 14–16‐year‐olds were asked to provide open‐ended answers to the question “What do you mean by learning?” Content analysis identified learning conceptions similar to those found in Western studies which are thought to underlie deep and surface approaches to learning. The second study investigates the reliability and validity of a...
