The standardized precipitation index allows for monitoring the intensity and spatial extent of droughts at different time scales. We used it to do a retrospective analysis of the spatial extent of droughts in Southern Africa (South of 10°S), from 1901 to 1999. Accordingly, the 8 most severe droughts at the 6‐month scale (October–April) for the summer rainfall region of Southern Africa ended in 1916, 1924, 1933, 1949, 1970, 1983, 1992 and 1995. At the 2‐year scale, they ended in 1906, 1933,...

This study focuses on 11 African American undergraduate seniors in a biology degree program at a predominantly white research institution in the southeastern United States. These 11 respondents shared their journeys throughout the high school and college science pipeline. Participants described similar precollege factors and experiences that contributed to their academic success and persistence at a predominantly white institution. One of the most critical factors in their academic...

This study examined the relationship between tobacco use and depression and its possible variation by gender among African American young adults. A paper-and-pencil survey was administered to African American college students graduating in 2003 from a Historically Black College or University (HBCU). Tobacco use measures included lifetime involvement. Depression symptoms were assessed using a revised version of the CES-D. Male smokers were found to be four times more likely to be depressed...

Society’s obsession with thinness and body image is part of every school’s hidden curriculum. The ideal to be skinny and thin resulted in an escalation in eating disorders among adolescents in South Africa. Some of the learners are only in the senior phase (Grades 7 to 9) of the general education and training band. It is therefore timely to review the problem of eating disorders, especially among adolescents in South African public schools. The purpose of this article is firstly to provide...

The use of computer-mediated communication in higher education presents opportunities for students to be part of an online learning community irrespective of their geographical location. However, students do not always avail themselves of this opportunity and pedagogic strategies for encouraging participation are therefore constantly being explored. One potential strategy to encourage participation is the use of the structured format of online debating. This paper proposes an underlying...

This article analyses the implications of institutional mergers for information systems development and in particular for the provision of blended and collaborative learning in the South African higher education system. The analysis is undertaken with particular reference to the new institutional shape as envisaged in the higher education merger plan, and with reference to the characteristics of current higher education information systems. This article will draw attention to the key...

The study was carried out to assess the extent to which university farms contribute to the teaching and learning of agricultural science in the five state universities of Ghana. The universities are the University of Ghana, Kwame Nkrumah University of Science and Technology, University of Cope Coast, University of Education and University of Development Studies. In the process, the study examined causes or reasons for graduate low interest in pursuing farming careers. Semi-structured...

Noise pollution in workplaces poses serious health risks including that of cardiovascular disturbances and impairment of hearing. The objective of this study was to assess the effects of occupational noise on hearing among selected industrial workers in Benin City, Nigeria. Male and female workers (n=150) in sawmills, Food Processing industries and Marketers of recorded music who had been exposed to high levels of occupational noise for between 1-14years were evaluated. We determined the...

Higher education in developing countries is facing a series of challenges. In Nigeria these challenges are multifaceted but one dimension that has attracted some attention is the phenomenon of secret cultism. While there are several commentaries few of these are either systematic nor scholarly. This paper is an attempt to rise to this challenge by attempting a systematic analysis based on an appropriate theoretical basis that can lead us to developing appropriate theoretical insight into...

Abstract Using spatial predictions of future threats to biodiversity, we assessed for the first time the relative potential impacts of future land use and climate change on the threat status of plant species. We thus estimated how many taxa could be affected by future threats that are usually not included in current IUCN Red List assessments. Here, we computed the Red List status including future threats of 227 Proteaceae taxa endemic to the Cape Floristic Region, South Africa, and compared...
