The February 22nd 2006 Mw = 7 Machaze earthquake is one of the largest, if not the largest, earthquakes reported since 1900 within Continental Africa. This large continental intraplate event has important implications to our understanding of tectonics and strong ground motion prediction locally and in the global context. Thus, accurate estimates of source parameters of this earthquake are important. In this study, we inverted the complete azimuthally distributed high frequency (0.05–2 Hz) P...

Millions of people are living with HIV worldwide, and more than half of these people are adolescent, aged between 12-25 years. Insufficient knowledge, bad attitudes and unsafe practices are major impediments in preventing the transmission of the virus. 420 students from grades 9-12 were selected through random sampling from different schools in Eastern Cape. The majority of students assessed (95.5%) were knowledgeable about the spread of the virus but 35.2 percent to 66.2 percent of them had...

The aim of this sociolinguistically-oriented study is to determine the elements of a suitable English Language syllabus for university students in Libya. The syllabuses currently being used to teach English Language in the Libyan Higher Education sector were originally designed back in the 1980s. In view of the sweeping changes which have taken place both in the role of English in the world and also in Libya itself since that decade, and in view of concurrent developments in language...

This study investigated factors that hinder the integration of Gambians with disabilities into mainstream society through focus groups and surveys. Stigma towards those with disabilities was perceived as common and more community education on the medical causes of disabilities is needed. Full integration surfaced as fundamental and to achieve this, more support is needed, including both concrete supplies as well as training.

ABSTRACT The Engare Sero Footprint Site, situated on the southern shore of Lake Natron in northern Tanzania, has been reported to host one of the best preserved sets of fossilized hominid footprints in the world. However, until now there has been no detailed characterization and age determination of the footprint‐bearing strata (the Footprint Tuff). Here, we combine field observations with geochemical and mineralogical analyses and measurements of the anisotropy of magnetic susceptibility to...

Using formal survey data from textile and leather product manufacturing firms in Ethiopia, we investigate how the current national cultural setup (power distance, collectivism, masculinity and uncertainty avoidance) is affecting organizational learning, orientation and product innovation performance. Further, we assess the moderating role of sector and ownership structure on the interrelationship. The result demonstrates that the current national culture setup is negatively affecting the...

Abstract Background: The World Health Organization recommends HIV testing and counseling (HTC) for all adolescents living in countries with generalized HIV epidemics. In Botswana, HIV prevalence among adolescents 15–19 years is 3.7% and among pregnant adolescents is 10%. We describe the proportion and characteristics of secondary school students who have accessed HTC. Methods: A multistage sample survey was conducted among students in Botswana’s public secondary schools in 2010. The survey...

This paper presents the findings of a qualitative study investigating which factors inside and outside the classroom result in feelings of stress for TESOL teachers working at private language schools in South Africa.Using in-depth semi-structured interviews, the findings reveal three main areas that cause stress for TESOL teachers: the job of teaching, relationships at work and organisational and TESOL-related issues.These three areas of stress can be further divided into various...

Integrating technology in pedagogy is a step for ICT capacity building for higher education to meet its current demands. Therefore, the integration of eLearning systems has been problematic, albeit huge investments in ICT infrastructure. This study investigates teacher adoption of a new upgraded eLearning platform being integrated at University of Rwanda. A six-constructs model related to technology adoption was used to design questionnaire and interviews. Closed and open-ended questions...

In East Africa, lepidopteran stemborers such as Chilo partellus and Busseola fusca are major constraints to production of maize, which is the main staple food crop in the region. Cereals depend on silicon (Si)-based defences to fight off herbivores. Using altitudinal ranges in the East African highlands as ecological surrogates for inferring climate change, it was shown that Si concentrations in soil and maize decreased with altitude. This was attributed, in part, to low temperatures at high...

The study sought to explore the gender differences in the reading comprehension of grade three rural learners whose mother tongue is IsiXhosa in the Eastern Cape of South Africa. A convenience sample of 95 learners (49 boys and 46 girls) based in one school participated in the study. An English language reading comprehension test and IsiXhosa reading comprehension test were administered to the learners. A quantitative design was employed in this study. A t-test was used to determine whether...

Globally, substance abuse by youths in rural areas appears to hinder all efforts to reduce the prevalence of this social ill. The objective of this paper is to raise debates and discourses on the underpinnings of drug abuse among the out-of-school youths and suggest solutions or newer perspectives to tackle the quagmire. The experimental design of this paper is of a quantitative approach. Principal observation from the findings show that out-of-school youths in rural areas seem to end up...

As developing countries move from policy to implementing adaptation to climate change, formal operational structures are emerging that exceed the expertise of any one actor. We refer to these arrangements as ‘meta-organisations’ that comprise many autonomous component organisations tackling adaptation. The meta-organisations set standards, define purposes, and specify appropriate means-ends criteria for delivering adaptation. Using empirical data from the three cases, Nepal, Pakistan and...
