Today, it has become fashionable to discuss closing the achievement We know that an achievement gap exists. The question is, what can be done to close it? In 2005, approximately 50 years after the first Brown vs. Board of Education court case, we issue the official call for others to join us in researching the mathematics and science education of African American students. It is our aim to encourage researchers, who have a sincere interest in the mathematics and science education of African...

UNLABELLED This study, intended to contribute to the fight against HIV/AIDS infection, sought to identify the factors limiting condom use among the pupils of the El Mina middle school in Nouakchott, in the Islamic Republic of Mauritania. METHOD This investigation, conducted in May 2004, concerned 711 students aged approximately 12-16 years.

Records of 349 tetanus patients, aged 10 years and above, admitted to the Lagos University Teaching Hospital, Nigeria, between 1990 and 1999 were reviewed. The male:female ratio was 1.98:1, and the ages were between 10 and 88 years, with a mean age of 29.8 years. The overall case fatality rate (CFR) of tetanus was 36.96% (33.19% for men and 44.44% for women). The CFR is similar to that previously reported in the hospital, but higher than that reported from Europe and North America. The...

In this study, trace metal analysis of the surface waters from river Dzindi, Madanzhe and Mvudi in Thohoyandou, South Africa, were conducted with a view to obtain a baseline data of their levels. The physico-chemical forms of the metals as a means of assessing their availability and non-availability for toxicity to aquatic organisms was also investigated. Surface water samples were collected randomly from selected sites in the rivers aforementioned. The samples were analysed for Cd, Cu, Pb...

Although children are the most vulnerable group in any disaster, limited information exists regarding their unique needs in complex humanitarian emergencies.To review the experiences gained in designing and implementing a training course for international health care professionals in disaster management focused on the needs of children.The format, content, learning objectives, teaching methods, course evaluation, and feedback of a training course on managing complex humanitarian emergencies...

This paper examined the concept of social mobilization and guidelines that should be followed in social mobilization programming. It considered issues involved in information dissemination and what should be borne in mind in the designing of development messages. The paper also drew attention to communication training models which are hinged on radio study groups that could be adopted for the mobilization of Nigerians for social development. It recommended an appropriate strategy for...

ABSTRACT: The Nation is ill-equipped to meet the future demands for scientists to sustain scientific disciplines and the scientific literacy required in this technological era. In response to this state of affairs, reforms promote quality for all but provide little guidance on how to achieve it. This study describes an approach that uses cultural contexts as conduits for learning. With respect to Black Cultural Ethos (BCE), the study investigated eighth graders' self-reported preferences...

This article analyses the implications of recent institutional mergers for information systems development and in particular for the provision of blended and collaborative learning in the South African higher education system. The merged institutions are only beginning to address these challenges. The article therefore draws attention to current conditions, key systems integration challenges and strategic decisions that can influence the outcome of information systems integration. Particular...

The El Arraiche field is a new mud volcano field discovered near the Moroccan shelf edge in the Gulf of Cadiz that consists of 8 mud volcanoes in water depths from 200 to 700 m. The largest mud volcano in the field (Al Idrissi mud volcano) is 255 m high and 5.4 km wide. The cluster was discovered during a survey with the RV Belgica and studied further during Leg 2 of the TTR 12 survey onboard the R/V Prof Logachev. The 2002 surveys yielded detailed multibeam bathymetry over a 700 km2 study...

High-resolution analyses of the elemental composition of calcite and biogenic silica (BSi) content in piston cores from Lake Edward, equatorial Africa, document complex interactions between climate variability and lacustrine geochemistry over the past 5400 years. Correlation of these records from Lake Edward to other climatically-forced geochemical and lake level records from Lakes Naivasha, Tanganyika, and Turkana allows us to develop a chronology of drought events in equatorial East Africa...

ABSTRACT: Historically, lack of access to opportunities has been a constant and unfortunate reality for many African Americans. As a result of tracking and ability grouping many African American students lack the necessary accoutrement for persistence in the sciences. Some critical factors for the persistence and success of African American students in college science degree programs includes parental involvement, teacher expectations, increased numbers of science and mathematics courses,...

Compared with the disability associated with repeated seizures or side-effects of antiepileptic medications, the social stigma associated with epilepsy is often a major handicap to people living with this condition. This study therefore looked at the knowledge, attitude and perception of teachers who see a lot of epileptics, relates on daily bases and have a high influence on students with epilepsy. Self-administered questionnaires were used to obtain information from 460 randomly selected...

The notion that South African public schools have a distinctively civic mission has been recognized in all national education policy documents published since the first democratic election in 1994. The African National Congress (ANC) government immediately began to realize that if the new-found democracy was to survive, education for democratic citizenship had to be taught to every future generation. The purpose of this article is to summarize scholars' views on the attributes of a good...

In South Africa where poverty defines the lives of the majority, technological resources are not just limited and unequally distributed in schools, but also their availability does not necessarily translate into use. The paper explores issues related to accessibility and (non-) use of technology for mathematics learning and teaching in poor schools in South Africa. A suggestion is made to consider poverty and economic conditions as legitimate and relevant concerns in research on technology in and for mathematics education.

Cereals have a great importance in agricultural research programs worldwide. As far as Tunisia is concerned, they are all the more vital as the country is seeking to reach a stable production in cereals, especially in durum wheat and barley. However, Tunisian cereal crops are highly dependent on climatic conditions and they have to face frequent droughts. Cereal production under water deficit conditions has been the subject of a number of studies which showed that cereals are equipped with...
