We used quantitative textural measurement, electron microprobe microanalysis and thermobarometry on clinopyroxene from a Cenozoic pyroxene-nephelinite flow located along the northern boundary of the West African craton to decipher magma differentiation processes in underlying magma chambers. The crystal size distributions of clinopyroxene phenocrysts show straight but also curved and kinked patterns and the clinopyroxene show large compositional variations in a single flow (Mg-number 48-88)....

This paper explores the salience of sport in the lives of eight‐year‐old and nine‐year‐old South African primary school boys. Drawing on ethnographic and interview data, I argue that young boys' developing relationship with sport is inscribed within particular gendered, raced and classed discourses in South Africa. Throughout the paper I show differences and durability of meanings across the social sites that affect and position blacks, white, boys and girls. It is argued that young boys'...

This paper is aimed at investigating the secondary school experiences of Ethiopian (Ethio)-Australian students living in Melbourne. A qualitative methodology was employed using interviews and observations as data collection instruments. Secondary school students, their teachers and parents acted as participants of the study. The findings of the study included a deeper understanding of the exclusionary forces that contributed to the students' attendance and learning in the secondary schools...

In the past decade, Oxfam has streamlined and restructured its global activities in an attempt to professionalise and strategise. This move has affected the relationship between different Oxfam components and between Oxfam and its partners. A three layered approach, looking at structural elements, ideational elements and organisational learning, is used to pick apart the restructuring and its effects within the Oxfam GB head office, the Oxfam Ugandan Country Office, The National Union of...

Only 30% of college students meet the recommended amount of physical activity (PA) for health benefits, and this number is lower for African American students. Moreover, the correlates of PA may vary by ethnicity. Objective: In the present study, the authors tested the utility of the theory of planned behavior for explaining PA intentions and behavior in Caucasian and African American students. Participants and Methods: Participants were 238 African American (M age = 20.05 years, SD = 2.28)...

Higher education at the Alice campus of the University of Fort Hare is a challenge, for the majority of the students come from rural villages, in which a traditional and above all oral culture determines the pivotal life. But in terms of the strategic plan of the university, the departments are committed to raising academic standards and to ensure a certain pass rate.

This research aims at quantifying the effect and importance of considering future climate change on large-scale infrastructure in a developing country context. Plans are underway for major hydropower development in Ethiopia, a water resources-rich nation, yet consideration of climate change on design, operation, and eventual benefits of the system remains uncharted. If current strategies are reliant on stationary climate, what future climatic conditions could warrant measurable design...

Ethiopia possesses abundant water resources and hydropower potential, yet less than 5 percent of irrigable land in the Blue Nile basin has been developed for food production, and more than 80 percent of Ethiopians lack access to electricity. Consequently, the Ethiopian government is pursuing plans to develop hydropower and irrigation along the Blue Nile River in an effort to tap into this underused potential. Although approximately 84 percent of the inflow to Lake Nasser at Aswan, Egypt,...

Numerous studies indicate that agricultural production is sensitive to climate variability, and lack of infrastructure in developing countries increases vulnerability to extreme climate events. In Ethiopia, the historical climate record indicates frequent droughts and floods, which can devastate agricultural production and existing infrastructure. Too much precipitation can flood crops, rot or suffocate roots, and wash out roads, creating similar economic conditions to those resulting from...

There is growing concern in Africa about the use of computers to support learning in educational institutions. Information and communication technologies (ICT) are used to gather, analyze, modify and exchange information. They are used in almost all spheres of human activity. The computer and the internet are increasingly making their way into teaching and learning practices and processes. This paper discusses teachers’ readiness for the use of ICT in Ghanaian schools. Findings come from...
