A national survey was carried out to assess the prevalence of helminth infections in all four geographical zones of Guinea (the four official names should be used. Guinée forestière, Haute Guinée, Moyenne Guinée and Basse Guinée) to provide information on which a school-based intervention program could be developed. The program, financed by the World Bank, would consist of vitamin supplementation, antihelmintic treatment and hygiene education.The survey was conducted between April and June,...

Recent studies in water quality management have focused on the use of benthic macroinvertebrates in the environmental impact assessment of pollution on aquatic communities. The benthic macroinvertebrates of a stream passing through Kampala, the capital city of Uganda, were studied. Eleven taxa, comprising a total of 290,607 individuals, were collected. The tubificid Limnodrilus hoffmeisteri was the most abundant species contributing over 99 % of the total invertebrates. Faunal distribution...

Primary schools in developing countries, even in urban centers, lack general school health personnel as well as eye-care professionals. In this situation pupils' visual acuity problems may often go undetected, setting the stage for poor performance in school and later in life. Students and staff of the African Regional Health Education Centre in Ibadan, Nigeria worked with primary school teachers in one traditional poor inner-core community of Ibadan to identify their willingness to...

In this study, marine surface sediments are collected from nine locations along the Suez Canal in order to investigate the relationship between the morphology of sands in the studied beaches and pollution by oil. Basically, the studied samples were analyzed by three techniques: grain-size analysis, microscopic examination, and gas chromatographic (GC) analysis. This study concluded that “medium sand” is the major class represented in the studied marine sediments. Pollution in these sand...

This paper presents new seismic hazard maps of the Maghreb countries by using newly re-evaluated earthquake data catalogue in the region under consideration. For this region, there is a clear need to use common procedure and data bases through the whole Maghreb region so that seismic hazard assessments are consistent from country to country. An effort is made to assess the seismic hazard and to construct earthquake hazard maps in terms of expected horizontal and vertical PGA for a 10 per...

In Ethiopia, the overthrow of the military government of the Dergue in 1991 ushered in a period of political reforms which are still in progress, including a policy of recognition of a range of indigenous languages other than the traditionally dominant national language, Amharic. This paper addresses the question of language planning and education in this pluralist, multilingual state. It presents a profile of some of the many languages in use within the country, both indigenous and foreign,...

ABSTRACTS At a time when South Africa is in the throes of transition, ideologies in the educational, medical, economic and social spheres are being redefined and redirected. The field of speech pathology and audiology is no exception. The Department of Speech Pathology and Audiology, University of the Witwatersrand has acknowledged an urgent need to address the requirements of a multilingual and multicultural South Africa and extend training beyond the white middle‐class population. It is...

The first part of the paper discusses the uneven distribution of resources to higher education between the North and South. It then takes up the attitude of the World Bank towards university education in the South and does this by going through several World Bank publications and dwells on the 1994 publication called ‘Higher Education: The Lessons of Experience’. It also discusses the likely effects for the university sector in the South, especially in Africa, of the Jomtien conference on...

Abstract This article reviews conditions in the East African country of Kenya that put students at an advantage for learning second languages. The author focuses on a group of students with mental retardation, a group historically regarded by some as being poor second language learners. Examples are cited of students attending a special education school for the developmentally disabled in Nairobi who demonstrate fluency in three or more languages. Students’ proficiency in these languages is...

In South Africa, the post-apartheid government has committed itself to an integrated approach to education and training. This article addresses South African policy debates, illustrating that global trends such as integration are shaped by significant local influences in the production of specific policy positions. The integration debate in South Africa reflects both equity and human resource development concerns, and is more fully developed in adult basic education and training than in...

To study the prevalence of glucose intolerance in adult urban and rural populations in the northern parts of Sudan.A sample of 1,284 subjects aged > or = 25 years was selected using a multistage cluster method and underwent a 75-g oral glucose tolerance test.The crude prevalence was 3.4% (men, 3.5%; women, 3.4%) for diabetes and 2.9% (men, 2.2%; women, 3.3%) for impaired glucose tolerance (IGT). The highest crude prevalence was in the northern parts of Sudan (5.5%) and the lowest in the...

Intervention to control the spread of HIV/AIDS in out of school youth is under way in Bahir Dar Town. This survey was therefore conducted in April 1994 to provide baseline data on sexual behaviour, knowledge and attitude towards HIV/AIDS. A total of 1115 out of school young people from eight randomly selected kebeles of the town were interviewed. Fifty one (4.6%) respondents said they have never heard of AIDS. Mean number of sexual partners for those who practised sex was 3.9 +/- 2.5....

ABSTRACT This study evaluated the Minority Academic Advising Program (MAAP), a supplementary retention program established for African-American students enrolled in a southern state health sciences university's baccalaureate nursing program. The evaluation method merged a quasi-experimental with a time-series design. A group of 114 black students were included in the study. A comparison group consisting of 608 nursing student cohorts who were predominantly white was incorporated for control...

The southern African region is susceptible to climatic extremes and particularly to extended dry periods. Possible changes in the probability of dry years under doubled-CO2 conditions are examined using output from the CSIRO nine-level general circulation model. Changes in annual mean rainfall are not expected to be significant. However, the model simulates an increase in the probability of dry years in the tropics, to the south-west of the subcontinent, as well as over the western and...
