Diatom genera in many large East African lakes change little throughout the Holocene period suggesting relatively stable ecological conditions and some resilience to environmental change. Ecosystem stability is less common in smaller, more sensitive lakes, such as those within volcanic craters, where external impacts can cause abrupt and rapid fluctuations. A 4100-year diatom and cyanobacteria pigment record from Lake Massoko, a volcanic crater lake in southern Tanzania, is used to...

The study looked at the knowledge and attitudes of social work students in Mauritius regarding AIDS. Seventy-six students participated in the survey.

Two of the...

South Africa's single electricity-generating utility ESKOM is considered to be the powerhouse of Africa. Proper industrial and residential demand-side management (DSM) of electricity usage could improve efficiency and contribute significantly to releasing spare generating capacity. South African tertiary education institutions have started energy-saving activities (the AfriCampus Collaboration) and work on energy conservation on their campuses. The various projects in the...

Due to lack of national cancer registry, the pattern and outcome of gastrointestinal tract (GIT) cancer is unknown in Ethiopia. In the period 1992-1996, a prospective study was carried out in 534 patients with GIT malignant tumours admitted to the Tikur Anbessa Hospital Department of Surgery, Addis Ababa. Relevant data were recorded on a prepared proforma for specific disease. Of these, 437 cases (82%), 142 oesophageal, 68 pancereato-biliary, 96 gastric, and 131 lower GIT cancers have been...

In this study of 62 African American families living in poverty, we examined the main and interactive effects of psychological, family, and school factors on students' grade point average across the middle school transition. Both parent interviews and student surveys were collected, resulting in three major findings. First, students experienced a significant decline in grade point average across the transition from elementary to middle school. Second, students who felt more academically...

This paper addresses the general question of why teachers teach in the way they do. Data collected from Egyptian science teachers both in the UK during an in-service course and on their return to Egypt are reported. The teachers' evaluation of which in-service experiences they thought of most use is contrasted with the changes they were able to bring about in their own teaching on return to Egypt. Follow-up interviews and classroom observations in Egypt showed the teachers to be frustrated...
