E-learning is becoming increasingly prominent in higher education, with universities increasing provision and more students signing up. This paper examines factors that predict students' intention to adopt e-learning at the Egyptian University of Mansourra. Understanding the nature of these factors may assist Egyptian universities in promoting the use of information and communication technology in teaching and learning. The main focus of the paper is on the university students, whose...

This essay problematizes the place of African thought systems and philosophies of education in the European Canon. It also looks at the theoretical and analytical perspectives this Canon has spread across the globe, which trivialized Africa histories, epistemic realities and epistemologies. The essay engages a brief summary of the works of select but prominent European philosophers and situates them in the context of European colonialism and post-colonial discursive hegemonies that continue...

Fluoride, a trace element with anticariogenic benefit may either occur naturally or be added to drinking water sources. This study aimed at determining the fluoride level of the different drinking water sources in Ibadan, Oyo State, Nigeria and to relate this with the caries experience of secondary school children in the city. Sixteen samples of the drinking water sources from various locations in the five local government areas of the city were analysed for fluoride concentration. The...

The purpose of this study was to evaluate the impact of a multi‐dietary strategy to treat IDA in adolescent girls. A quasi‐experimental design involving 34 intervention and 34 control girls aged 12 to 17 years and suffering from mild IDA was carried out in two boarding schools from southern Benin. IDA was defined as haemoglobin (Hb) between 100–120 g/L and serum ferritin (SF) <20 μg/L or serum ferritin between 20–50 μg/L plus two of the following parameters: serum iron <11 μmol/L,...

According to the UN estimation, currently, there are more than 650 million persons with different types of disabilities in the world. And in Ethiopia, it is expected to be more than 10 -------Million at national level. But, unfortunately, the number of students with disabilities at higher educational institutions is not known. For the fact that persons with disabilities are human beings, they have the fundamental rights that hlunan society deserves. These category of persons do have the...

Germany's existing biodiesel production plants had a total annual biodiesel capacity of more than 3 million tonnes (Mt) in 2006, while most of the countries in Africa have just initiated a first phase of biodiesel development. Commercial viability of manufacture of biodiesel for use in transportation can be facilitated in Africa through a better understanding of the economic and other factors that have contributed to the success of Germany's biodiesel industry. A cost-capacity factor n =...

This article explores the process of professionalizing legal drafting in Commonwealth Africa. It is argued that, in view of the centralized drafting system, the linguistic skill of the legal drafter must be complemented by the skill of the administrative or departmental officials to provide policy and substantive inputs in the drafting of Bills. The object of this article is to draw attention to the need for the systematic training of administrators so as to prepare them effectively for...

A total of 206 urine samples collected from Hassoba Elementary schoolchildren, Afar, Ethiopia, a low Schistosoma haematobium endemic setting, was diagnosed to evaluate the performance of CCA strip using double references, urine filtration technique and urinalysis dipstick (Combur 1.0 Test) that detect schistosome eggs and blood in urine, respectively. The former was used as a gold standard reference method. Sensitivity, specificity, positive and negative predictive values for the CCA were...

Abstract This article aims to investigate changes in primary school students’ reported exposure to AIDS information and communication, and knowledge levels from 1992 to 2005. A repeated cross-sectional design was used. In 1992, a self-administered questionnaire was completed by 2,026 sixth and seventh grade students from 18 randomly selected primary schools in Arusha and Kilimanjaro regions, Tanzania. The same procedures were repeated in 2005 with a sample of 2,069 students. Mean values with...

The sediment records of three shallow climate-sensitive lakes in equatorial East Africa (Chibwera and Kanyamukali in western Uganda, and Baringo in central Kenya) contain clear lithological evidence of an episode of complete desiccation in the relatively recent past. Quantitative stratigraphic analyses of bulk sediment composition, texture (% sand and coarse organic detritus), the C/N ratio of bulk organic matter, and magnetic susceptibility allowed us to define a common succession of...

Women's physical and psychological access to health care was analyzed using the 2003 Ghana Demographic and Health Survey (GDHS), a nationally representative study for monitoring population and health in Ghana. Female respondents from the 2133 cases in the couple's data set were used in this study. Women's level of education was positively related to physical but not to psychological access to health care. Residing in an urban area was positively related to both types of access. Matriliny...
