Since Brown and Gilman’s (1960) study, sociolinguists have shown an increasing interest in the use of address forms in various social domains such as politics, workplace, religion, and acdemia. This study shows how students in a Ghanaian university address one another in varied linguistic forms. To accomplish this task, a three-pronged conceptual framework derived from interactional sociolinguistics and an ethnographic-style research design are adopted. Three key findings emerged from the...

However, concerns about the quality of teachers and teaching in Tanzania persist (Massawe and Kipingu 2000; Kuleana Center for Children's Rights 2001; MOEC 2003, 2004a; Rajani and Sumra 2003; Sumra 2004a; Davidson 2005). One factor that has had a significant impact on...

Levels of Zn, Cu, Cd, As, and Pb in the kidney, Liver, Gills and Heart of African cat fish (Clarias gariepinus) from the Ogun River in Ogun State located close to six major industries in the South Western part of Nigeria, were determined using Bulk Scientific Atomic Absorption Spectrophotometer. Fishes were also collected from Government owned fish farm in Agodi, Ibadan which was considered a reference site. The activities of superoxide dismutase (SOD), catalase (CAT), glutathione...

A total of 36 patients were seen and managed at the Ladoke Akintola University of Technology Teaching Hospital, Osogbo, Osun State, Nigeria, over a period of five years (2000 to 2004). There were 28 males and 8 females (male to female ratio, 3.5:1). The ages ranged from 1 to 46 yr (mean, 14.5 yr). The burn surface area percentage ranged between 2.5 and 70% (mean, 22.9%). Flame constituted the commonest source of injury (66.7%). Other agents were scalding (9 patients = 25%) and electrical...

In 1998, Kenya adopted intermittent preventive treatment (IPTp) with sulphadoxine-pyrimethamine (SP) for malaria prevention during pregnancy. We conducted a survey in 2002 among women who had recently delivered in the rural neighbouring areas Asembo and Gem and reported coverage of 19% of at least one dose and 7% of two or more doses of SP. Health care workers (HCW) in Asembo were retrained on IPTp in 2003.To evaluate if IPTp coverage increased and if the training in Asembo led to better...

To compare the composition of cytokines in African American and Caucasian patients with systemic sclerosis (SSc; scleroderma) and in healthy individuals, particularly the expression and function of hepatocyte growth factor (HGF).Bronchoalveolar lavage (BAL) fluid samples were analyzed using cytokine array techniques.
