Since 2000, Zimbabwe's government, as well as other international aid organizations, have repeatedly blamed the country's sharp economic downturn on persistent and severe droughts. Indeed, past research has shown strong links between rainfall and maize yields in sub-Saharan Africa, suggesting that the lack of rainfall is an attractive culprit for the recent collapse of Zimbabwe's agriculture-based economy. This article probes this hypothesis further, by examining primary data from 38...

A test instrument, made up of 25 items, derived from existing standardized tests from literature, was used to probe for the students' knowledge and understanding of basic mechanics concepts, as well as the confidence in the correctness of their answers. The test was administered to 982 first entering physics students; enrolled at three South African universities, at the beginning of the year before any formal instruction could take place. Data collected for this study included students'...

In Zambia 57% of births occur at home under the supervision of unskilled attendants. This situation poses a danger to the lives of both delivering mothers and their newborns.

The purpose of the study, therefore, was to explore Zambian midwifery...

Madagascar's rainforests are among the most biodiverse in the world. Understanding the population dynamics of important species within these forests in response to past climatic variability provides valuable insight into current and future species composition. Here, we use a population-level approach to analyse palaeoecological records over the last 5300 years to understand how populations of Symphonia cf. verrucosa became locally extinct in some rainforest fragments along the southeast...

Stabilised earth is an alternative building material which is significantly cheaper than using conventional brick and concrete, and is also environmentally sustainable. Earth has been used as a construction material in every continent and in every age. It is one of the oldest building materials. The use of earth on site as a building material saves manufacturing cost, time, energy, environmental pollution and transportation cost. Most African countries do not have any well-structured and...

Abstract Aid policy and practice have been thoroughly shaken up over the past few years. One of the reform areas relates to monitoring and evaluation (M&E). In short, aid recipients are asked to elaborate result‐oriented frameworks while donors are expected to harmonise and align their policies and frameworks. This article examines the extent to which joint sector reviews (JSRs) could take the M&E reform agenda forward. JSRs are M&E exercises at the sector level which have the...

The focus of this paper is on selected recent South African research studies that have explored efforts to promote the discussion, writing, and arguing aspects of scientific literacy in primary and middle schools, particularly amongst second-language learners. These studies reveal improvements in the participants’ abilities to both use the ‘science notebooks’ approach and argue their findings, as well as statistically significant improvement in their problem solving skills. The positive...

Background: Fractures in the elderly in West Africa have been reported infrequently in the literature. A study of the pattern of fractures in the elderly as seen in a major urban trauma centre in Nigeria should give some indication of the magnitude of the problem and help to fashion out preventive measures.Methods: This prospective study included all patients aged 65 years and above with fractures of the extremities seen over a period of 18 months. Data collected included age, sex, trauma...
