The north-western sector of the Gharyan volcanic field (northern Libya) consists of trachytic-phonolitic domes emplaced between ~ 41 and 38 Ma, and small-volume mafic alkaline volcanic centres (basanites, tephrites, alkali basalts, hawaiites and rare benmoreites) of Middle Miocene-Pliocene age (~ 12–2 Ma). Two types of trachytes and phonolites have been recognized on the basis of petrography, mineralogy and geochemistry. Type-1 trachytes and phonolites display a smooth spoon-shaped REE...

Orientation and mobility (O&M) practice is important because the population of persons with visual impairments is large enough to warrant planned action on measures to help them acquire independence and sustain their livelihoods. Most O&M practitioners in South Africa are full-time employees in nongovernmental organizations. The few who work in public service work in schools. The research presented here sought to explore and describe the current state of O&M practice in South Africa as...

Developing practices of inclusion worldwide pose a challenge as the concept of inclusion is most often conceptualized differently making it difficult to have a uniform approach towards the process of implementation. This paper reports on the process whereby action research was employed in order to develop inclusive practices in a South African school context. The research approach was qualitative and several data collection techniques were used. These included a series of meetings, daily...

The states of inclusive pedagogy in South African schools remain bleak and teachers are in the dark about what constitutes an inclusive pedagogy in the South African context. This is despite policy changes since the advent of the new educational dispensation in 1994. In this review article the researcher presents the background in terms of inclusive education developments, both within historical and policy contexts. While articulating the conceptualization of inclusive education, the paper...

The North Tanzanian Divergence zone (NTD), at the southern end of the eastern branch of the East African Rift, is part of one of Earth's few currently active intra-continental rift systems. The NTD preserves a complex tectono-magmatic evolution of a rift in its early stage of activity. The oldest magmatism reported in the NTD is associated with the centrally located Essimingor volcano. Although major element oxides show narrow compositional variations suggesting fractional crystallization,...

Abstract Recent studies on the pelagic ecosystem of Lake Kariba identified a number of changes in its thermal regime, planktonic communities and fishery production, concluding they were the result of climate change, particularly warming. This study re‐examines these conclusions and suggests alternative explanations for these changes. Historical data suggest there was no warming of the lake until at least the 1990s. Furthermore, lack of recent data makes it difficult to conclude that the...

Diabetes is an important contributor to the burden of disease in South Africa and prevalence rates as high as 33% have been recorded in Cape Town. Previous studies show that quality of care and health outcomes are poor. The development of an effective education programme should impact on self-care, lifestyle change and adherence to medication; and lead to better control of diabetes, fewer complications and better quality of life.Pragmatic cluster randomized controlled trialParticipants: Type...

AbstractThe main inhabitants of the Eastern Cape Province in South Africa are the Xhosa people. Myths and beliefs are part of every culture. This paper focuses on the myths about the acquisition of Cysticercosis and Taeniasis amongst the Xhosa university students in the field of health promotion. The research was a cross-sectional survey. A convenience sample was used. The sample was a group of students in one class, an intact group. Data were collected through a questionnaire from the first...

The Pello Hill scoria cone displays widely different characteristics dependent on which side of the cone is studied. This follows as a direct result of a strong depositional asymmetry (i.e., the crater rim varies between 14 and 111 m in height), preferentially depositing material to the northwestern side of the construct. This is interpreted to reflect sedimentation from a sustained eruption plume (with prevailing winds at the time of the eruption coinciding with the direction of maximum...

CURRENT CONDITIONS Mozambique’s diverse climate is influenced by monsoons from the Indian Ocean and the hot current of the Mozambique Canal. The country’s location makes it particularly vulnerability to climatic hazards such as drought, floods, and recurring tropical cyclones during the rainy season, which spans from October to April. Agriculture is the major activity of most of the population, contributing about 24 percent of the country’s gross domestic product. The major crops are...

There is an emerging consensus that promoting gender justice in value chain development is not only a rights issue for women, but makes ‘business sense’ for households, enterprises, and ultimately the national economy. This article discusses experiences using a community-led methodology, Gender Action Learning System (GALS), with producers and traders of coffee, maize, fruits (avocados, pineapples, and passion fruit), and beans in Kasese District, Western Uganda. This community-led value...

Abstract This article is concerned with benchmarking the oral English skills of a small sample of Grade 6 learners in a local KwaZulu-Natal primary school where English is not the first language for either teachers or learners, but is the language of learning and teaching (LoLT). A structured assessment was made of learners’ oral English skills based on the Common European Framework of Reference (CEFR) for assessing language skills across the languages of Europe, using material available...
