Variations in the temporal and spatial distribution of solar radiation caused by orbital changes provide a partial explanation for the observed long-term fluctuations in African lake levels. The understanding of such relationships is essential for designing climate-prediction models for the tropics. Our assessment of the nature and timing of East African climate change is based on lake-level fluctuations of Lake Naivasha in the Central Kenya Rift (0°55′S 36°20′E), inferred from sediment...

The perceptions of African American university students and how they construct meaning from high school experiences were examined. Five African American students from two large cities, attending a moderately selective university in the Midwest, served as a focus group for the study. An open-ended, semistructured questionnaire was used to guide the discussion for this qualitative study. Findings suggest that these students have transcended, to some extent, the attitudinal disconnect from...

The families of 24 African American children having severe emotional or cognitive disabilities who were receiving special educational services in urban communities were interviewed about their perceptions of cultural sensitivity demonstrated by the school district. This information included their perceptions of the level of consideration of cultural beliefs and values within the services and supports provided by the district and by other community resources. Semistructured interviews were...

Abstract Thirty‐three senior high‐school biology teachers in Harare, Zimbabwe, participated in the study. Self‐report data on school contexts was used to cluster the teachers according to their own perceptions of the contextual circumstances in their schools. The clustering differentiated self‐perceived better and poorer resourced schools. In theory lessons, teachers from the self‐perceived better resourced schools were observed to use less individual organization, less written exercises,...

The objective was to examine the applicability of an abbreviated version of the oral impact of daily performances (OIDP) inventory to Tanzanian adults attending the University of Dar es Salaam.A total of 1123 students (mean age 26.4 years, response rate 58%) completed a survey instrument designed to measure subjective oral health indicators including the eight-item OIDP frequency scores. After a period of 4 weeks, 228 students (mean age 24.6 years, response rate 65%) were examined clinically...

Abstract Aim The aim of this study was to investigate the prevalence of illicit drug use, cigarette smoking and alcohol drinking behaviour among a sample of high‐school adolescents in the Pietersburg area (Central Region) of the Northern Province, South Africa. Participants Participants in this study were 435 secondary‐school adolescent students around the Pietersburg area (Central Region), in the Northern Province. Two hundred and forty‐three (56%) participants were female and 192 (44%)...

Sangatronics is a nationwide programme to provide practical electronics instruction for students taking advanced level physics, comprising five-day courses at a youth camp, where an intensive combination of theory, experiment and recreation has proved effective for over 2000 students. The locally-produced electronics kits and course notes are described in the paper, together with an evaluation of the project.

In this paper we propose some possible satellite uses in education with special emphasis on interactive data services such as digital data broadcast and turbo Internet. The case of the Nilesat satellite in Egypt is considered. A contribution to the identification and formulation of the best use of Nilesat to support national education programs in Egypt is given. Different satellite-based education applications suitable for the basic education, higher education and continuous education sectors in Egypt are proposed.

Abstract We present the evaluation of a pilot videotape training program for older African American women in constructive conflict resolution. The program was developed because research shows: (a) older African American women suffer disproportionately from hypertension, (b) hypertension is linked to anger inhibition, and (c) older African American women tend to inhibit their anger in interpersonal conflict. Community-dwelling and institutionalized older women participated in the training....

African higher education institutions are at a stage where they are striving to im- prove their information and communication technologies (ICTs) infrastructure, con- tent, and skills; making resources available to meet the growing needs of students and faculty; and responding to the pressure for effectiveness. They are also con- fronted with a dilemma of turning ongoing ICTs initiatives into opportunities and understanding what ICTs mean to the transformation of higher education in general...

This article analyzes the higher educational policies made for Sub-Saharan Africa by the World Bank and portrays its hostile attitude towards higher education development on the sub continent. Though an organization such as UNESCO holds up the Universal Declaration of Human Rights that states “higher education shall be accessible to all, on the basis of merit,” the Bank insists on what it calls diversification of funding and “cost sharing”. The ramifications of these policies both at...

This paper uses gender analysis to reflect on the emergence and development of higher education in Africa. The available statistical picture indicates that despite the absence of formal exclusions, women’s entry into higher educational institu- tions—as students and as employees—has remained slow and uneven, suggesting the need to look beyond the numbers. The overall pattern of exclusion and marginalization is true for both administrative and academic tracks but is at its most extreme for...

The Egyptian Air Force is constructing an Aeromedical Research and Training Center in Cairo for the purpose of training personnel to meet the demands of high-performance flight. The Human Training Centrifuge is a key ingredient of the facility, providing rapid onset and sustained G/sub z/ exposure to pilots and air crew members for the purpose of teaching methods of increasing an individual's tolerance to extreme acceleration. The centrifuge, as well as six other physiological training...

The author considers the global principles and questions to be analyzed when one is studying how to implement education in technology on the African continent. The main sources are the Baha/spl acute/'i/spl acute/ teachings and some of the United Nations' statements of education, development, and literacy. The author introduces some of the experiences of the Baha/spl acute/'i/spl acute/ International Community in this field. He examines what the Baha/spl acute/'i/spl acute/ community...

This study examined the extent to which racial differences existed in self-reported intellectual and social gains between African American and White college students at predominantly White institutions. Taking into account the influence of an array of intervening variables, African American and White students reported significantly different intellectual and social gains in college. Implications for student affairs professionals are discussed.
