Storm water drainage is as important in arid and semiarid regions as in humid regions because it is not only a drainage problem but also water resources management and planning problem. In the West Bank, storm water drainage has not been given enough care and no intensive studies have been done. This paper studies the rainfall runoff process in the West Bank as a case study towards understanding storm water drainage in arid and semiarid regions, where the process has different...

Rushton and Skuy [Intelligence 28 (2000) 1.] found that White university psychology students in South Africa averaged between one and two standard deviations higher than African students on Raven's Standard Progressive Matrices. This new study was carried out to determine whether Feuerstein's Mediated Learning Experience would improve the scores of the African students. The sample comprised 70 African and 28 non-African first year psychology students. Subjects were given the Raven's on two...

Impairment of renal function may occur as a result of a variety of conditions. Progression to chronic renal-disease may be prevented by early detection. This epidemiologic study aimed at revealing the predisposing factors and determinants for the development of impaired renal function among Egyptian children.This is a case-control study conducted at Alexandria University Children's Hospital, Alexandria, Egypt. All cases below 12 years of age diagnosed with impaired renal function over a...

South African companies employing 50 or more employees or those with a specified financial turnover, are required to comply with the provisions of the newly introduced Employment Equity Act. Prior to the introduction of the Act, large companies in the country had already introduced strategies of affirmative action to achieve employment equity. This paper highlights some of the strategic and operational concerns surrounding employment equity legislation in South Africa and reviews broad...

40Ar/39Ar dating of mineral separates and whole-rock samples of rhyolitic ignimbrites and basaltic lavas from the pre- and syn-rift flood volcanic units of northern Ethiopia provides a temporal link between the Ethiopian and Yemen conjugate rifted volcanic margins. Sixteen new 40Ar/39Ar dates confirm that basaltic flood volcanism in Ethiopia was contemporaneous with flood volcanism on the conjugate margin in Yemen. The new data also establish that flood volcanism initiated prior to 30.9 Ma...

This study examines spirituality and religious participation among African American and European American college students. Although the terms spirituality and religious participation have been used interchangeably in some research literature, this study measured them as two distinct constructs. Of particular interest was the relationship between these variables and academic performance. A questionnaire developed by the research team was administered to 192 (109 European American, 83 African...

Noting the need to develop strategies to ease the transition of children from families recently arriving in the United States from Gambia into the public school system in New York City, this paper compares the school life in Gambia with that of Bronx, New York. Information on school life in Gambia was obtained through literature and through interviews of 2 parents and 4 children, ages 8 to 10 years, from Gambia presently living in the Bronx. The paper describes the typical school life of a...

In accordance with the South African Constitution and the South African Schools Act, the Department of Education's Language-in-Education policy aims to promote multilingualism and the development of the official languages and to pursue the language policy most supportive of general conceptual growth amongst learners. The majority of South Africans prefer English and not their home language as language of learning and teaching (LoLT) after the first four years of schooling. Why? In an attempt...

The authors test two alternative models of learning to export: productivity learning, whereby firms learn to reduce production cost, and, market learning, whereby firms learn to design products that appeal to foreign consumers. Using panel, and cross-section data on Moroccan manufacturers, the authors uncover evidence of market learning, but little evidence of productivity learning. These findings are consistent with the concentration of Moroccan manufacturing exports in consumer items - the...

In August and September, throughout south central Africa, seasonal clearing of dry vegetation and other fire-related activities lead to intense smoke haze and ozone formation. The first ozone soundings in the heart of the southern African burning region were taken at Lusaka, Zambia (155 deg S, 28 deg E) in early September 2000. Over 90 ppbv ozone was recorded at the surface (1.3 km elevation) and column tropospheric ozone was greater than 50 DU during a stagnant period. These values are much...

This paper focuses on the current status and directions of human-computer interaction (HCI) education, research, and practice in Southern Africa.

About 500 km along the Great East Road from Lusaka, in Zambia, lies a mission hospital. This hospital serves a population of almost 200 000 subsistence farmers—a population devastated by AIDS. Mabvuto is 25 years old and is dying on the male medical ward of this hospital. He is cachectic and weak. He has chronic diarrhoea and cough. Oesophageal candidiasis makes swallowing painful. He had one child who died last year at the age of 2 years. He is HIV positive. He has been abandoned and...

During the period from 1991 to 1997 the School of Public Health and Tropical Medicine, James Cook University carried out filariasis surveys in several parts of Papua New Guinea using the newly introduced Onchocerca gibsoni monoclonal (Og4C3) and immunochromatographic test (ICT) antibody-based assays for filarial antigen and, in some cases, a Knott's test for microfilariae. The average prevalence of filarial antigenaemia and microfilaraemia was 56% and 35% respectively confirming earlier...
