This paper examines the tradeoff between commercial orientation and crop productivity among smallholder farm households living in drought risk-prone areas of the central rift valley of Ethiopia. The study was built on the hypothesis that there is a one-way causation between commercial orientation and productivity. The relationship between commercial orientation and crop productivity is assessed in a censored simultaneous equation model framework. Results indicate that there is a...

Abstract Among the challenges in Open and Distance Learning (ODL) generally and specifically within the African sub-region, is the difficulty to harness resources to regularly mobilize senior and mature academics as complacent learners to embrace continuous professional development, as a way of improving the quality of their academic performance. In order to change their conservative academic practises in many of the transformed African Tertiary Institutions (ATIs), this paper argues, that...

Chronology of Neoproterozoic volcanosedimentary successions remains controversial for many regions of the Arabian–Nubian Shield, including the Dokhan Volcanics of NE Egypt. New U–Pb zircon SHRIMP ages have been obtained for 10 silica-rich ignimbrites and two subvolcanic dacitic bodies, mapped as Dokhan Volcanics, from the North Eastern Desert of Egypt. Crystallization ages range between 592 ± 5 and 630 ± 6 Ma (Early Ediacaran). Apparently, the late consolidation of the Arabian–Nubian Shield...

Coastal social ecological systems in eastern Africa are subject to a range of environmental, social and economic changes. They are already vulnerable to these multiple stressors, and the impacts of climate change are likely to further exacerbate their vulnerabilities. Some of these impacts may be observed and experienced already. The analysis presented in this paper is based on mixed methods empirical research exploring local perceptions of recent changes at four sites in coastal Tanzania...

The retention of health care workers in developing countries is a key component to reducing the current health care workforce crisis. The availability of postgraduate medical training in developing countries could be an appropriate adjunctive solution. The authors investigated factors that led obstetrics-gynecology (ob/gyn) residents at a university-based academic training program at the Korle-Bu Teaching Hospital (Accra, Ghana) to stay in Ghana for training and explored why the residents...

The shortage of accounting professionals is well-documented. To address this shortage, greater numbers of school students should be attracted and enrolled in undergraduate accounting programmes. Unfortunately, school students may have misperceptions of the accounting profession. These misperceptions may result in potential entrants to the profession being lost to other professions. Secondary school teachers play an influential role in students' perceptions of future careers. This survey...

Parasitic helminthes are endemic in Nigeria, owing to poor environmental sanitation, pollution, and contamination of water and air. Children in Nigeria are highly exposed and very vulnerable to these infections, and these infections have adverse effects on their physical and mental development. School children, then, are good targets for mass-treatment programs against intestinal worms; treating children has been shown to reduce transmission to untreated members in communities. This study...

In recent years, more psychology programs are offering study abroad courses. These courses have the additional benefit of increasing student cultural competence. The goal of this study was to examine the impact of international education on a group of graduate students in psychology who participated in a 5-week travel abroad program to South Africa. Using a small convenience sample, a qualitative research design was used to explore student perceptions of engaging in clinical work in a...

The role of remediation in higher education has generated much debate over the last two decades. While states have enacted policies that reduced or eliminated postsecondary remediation, many policy actors and analysts have not completely acknowledged the ways in which remediation affects college access and success for African American students. This review of research first explains why African American students are disproportionately underprepared for college-level work. Then, the authors...

Because of low health literacy and low priority in seeking prenatal information, health education videos were explored for acceptability by Somali refugee women in a clinical setting.Focus groups led to the development of six targeted Somali prenatal education videos. Topics include: preparation for pregnancy, nutrition and exercise, pregnancy myths/facts, the father's role, episiotomies, and caesarean sections. Somali participants were recruited to view programs, and completed an 8-item...

Student attrition represents a waste of career opportunity and, at times, results in a holistic loss of sense of self-worth for the students involved. The aim of this study was to evaluate the nature, causes, and impact of medical student attrition in Nigeria.A pilot analysis was undertaken using the records of students who failed at medical school as a result of inability to pass the second MBBS examination at Ebonyi State University, Abakaliki, Nigeria, between 2002 and 2007. Some of these...

To examine 3 forms (am, is, are) of auxiliary BE production by African American English (AAE)-speaking children with and without specific language impairment (SLI).Thirty AAE speakers participated: 10 six-year-olds with SLI, 10 age-matched controls, and 10 language-matched controls. BE production was examined through samples and a probe.Across tasks, visual inspection suggested that the children with SLI overtly marked BE at lower rates than the controls, and all groups marked am at higher...

Some African grey parrots (Psittacus erithacus), the most famous being Pepperberg's parrot Alex, are able to imitate human speech and produce labels referentially. In this study, the aim was to teach ten African grey parrots from two laboratories to label items. Training three parrots from the first laboratory for several months with the Model/Rival method, developed by Pepperberg, in which two humans interact in front of the subject to demonstrate the use of a label, led to disappointing...

Technical vocational education and training (TVET) programmes have recently received increased attention as an area of priority for stimulating growth in developed and developing countries. This paper considers the situation in Ethiopia where the promotion of micro and small-sized enterprises (MSEs) has been central to the development and expansion of TVET centres throughout the country. The extent to which efforts relating to TVET made by Ethiopian policy makers, higher education...

This paper compares the effectiveness of in‐house developed computer‐based learning (CBL) materials with face‐to‐face teaching. Two groups of higher education students were randomly assigned to complete tutorial work in one highly structured topic of introductory accounting using either CBL materials (treatment group) or face‐to‐face teaching (control group). The effectiveness of both approaches was measured according to the students’ performance in a class test, in relation to their prior...
