The East African region exhibits considerable climatic and topographic variability. Much spatial and temporal variation in the response of different crops to climate change can thus be anticipated. In previous work we showed that a large part of this variation can be explained in terms of temperature and, to a lesser extent, water effects. Here, we summarise simulated yield response in two crops that are widely grown in the region, maize and beans, and investigate how the impacts of climate...

Abstract For years, the world has enjoyed the luxury of inexpensive transport fuels, resulting in the continuous expansion of transport demand and vast improvements in mobility levels. The threat of peak oil and other environmental concerns, however, are forcing a paradigm shift in terms of transport planning. In recent times, many developed nations have been investigating alternative ways and means of weaning themselves off oil as the main transport energy source and managing transport...

The underrepresentation of low-income African American girls in science-related careers is of concern. Applying the concept of positionality, the authors explored how three school counselors at low-resourced schools view this population of learners to either support or discourage mathematics and science careers. The results of this study suggest that these school counselors evidence lowered expectations for their students. The authors suggest that school counselors need to become aware of...

Hepatosplenomegaly among school-aged children in sub-Saharan Africa is highly prevalent. Two of the more common aetiological agents of hepatosplenomegaly, namely chronic exposure to malaria and Schistosoma mansoni infection, can result in similar clinical presentation, with the liver and spleen being chronically enlarged and of a firm consistency. Where co-endemic, the two parasites are thought to synergistically exacerbate hepatosplenomegaly. Here, two potential health consequences, i.e....

Objective To study skin sensitization as well as liver and kidney impairment in guinea pigs treated with trichloroethylene (TCE).Methods Guinea pig maximization test (GPMT) was applied in this study.Guinea pigs were divided into 3 groups,namely negative control,positive control and TCE treatment.Animals of 3 groups were administrated with olive oil,2,4-dinitrochlorobenzene (DNCB),and TCE,respectively,by intradermal injection.The animal skin was observed and blood was collected after various...

This paper was concerned with cultural bases of curriculum. It examined the influence of culture on curriculum development in Nigerian Schools since education is regarded as the transmission of culture in a process known as enculturation. It is a process of initiating the growing and inexperienced persons into the way of life in his society based on factors of culture which bring about changes in school curriculum. The school does not work in a vacuum, but has to operate in co-operation with...

Results-based management has gained currency in Kenya.  After pre-service training, teachers take various staff development programmes to enhance their role effectiveness. Many studies which have associated staff development with employee productivity have not delved into the actual mechanisms in which staff development impact on teachers’ effectiveness. This study was a survey of 100 primary schools which brought on board 100 teachers as research subjects. Using the outlier approach schools...

This paper examines the wellness attitudes of Secondary School Teachers in Cross River State, Nigeria. A descriptive survey research was adopted. 480 secondary school teachers were selected from both Public and Private Schools in Cross River State using deliberate sampling technique. A researcher- constructed questionnaire (r = .86) was the main instrument for data collection. Percentage frequency was used to analyze the data. The study revealed that the teachers were having negative...
