Too much or too little rain can be a matter of life or death in Africa. At different times and in different places across the continent, climate change threatens both. This briefing brings up to date the original report from the Working Group on Climate Change and Development, Africa - Up in smoke?, released in 2005. Note: a figure cited in this 2006 report on maximum temperature rise in Kericho, Kenya (page 5) has been questioned (February, 2013). The statistic was from the following study...

This paper proposes an innovation on HIV prevention, in response to the United Nations Millennium Development Goal to combat HIV/AIDS. The curriculum innovation is through a participatory action research design of life skills based education course, involving both health faculty tutors and first year distance education students at the University of Swaziland. The innovation builds onto the strengths of previous HIV prevention interventions and argues that effective life skills based...

ABSTRACT The Global Strategy for Plant Conservation (GSPC) aims to protect 50% of the most important areas for plant diversity by 2010. This study selects sets of 1‐degree grid cells for 37 sub‐Saharan African countries on the basis of a large database of plant species distributions. We use two reserve selection algorithms that attempt to satisfy two of the criteria set by the GSPC. The grid cells selected as important plant cells (IPCs) are compared between algorithms and in terms of...

Two separate lines of investigation were adapted from the recommendations of the 1994 United States Country Studies Program (USCP).In one approach, arbitrary incremental scenarios were adopted to assess the response of crop yield to changes in the various elements of climate.Using the erosion productivity impact calculator (EPIC) crop model, tests were conducted to demonstrate how crop yield might respond to changes in rainfall, relative humidity (RH), temperature, solar radiation and CO 2...

Severe environmental degradation appears to be threatening the long-term development prospects of countries all over the world, particularly the developing ones such as Nigeria. The paper reviews relevant literature and examines the process of environmental degradation via water pollution in Nigeria. While it notes that a careful management of water as a resource is essential for meeting a major demand created by accelerated urbanisation, industrialization and agricultural development, it...

The performance of radio communication system can be severely degraded by the presences of Radio Interference RI signals. Indeed, this degradation may be overcome to a some good extent by using various modern coding and modulation techniques. However, the effectiveness of these techniques depends, highly on the power level of RI signals. Better still if the RI signal can be suppressed at the output of the antenna prior to entering the receiver. In this paper we propose a viable scheme for RI...

E-learning is a new form of education and is a tool to reach students everywhere. In Gaza Strip it was used to solve the difficulty in movement problem. It was used as an enhancement tool in the educational process. IUG started experimenting with e-learning since 1999. IUG started a systematic approach in developing it e-learning teams. Joint partnership with Middlesex University help set up a system. Couple of courses were available to all university students and limited success was enjoyed

This article deals with our experience in designing a Computer Supported Collaborative Learning (CSCL) environment for science learning/teaching in Tunisian Primary School. We present CSCL particularities and addresses requirements elicitation in such system. In studying CSCL environments, we distinguished between pedagogical, ergonomic and psychological, and functional requirements. We have chosen the theoretical Activity Theory framework for eliciting and discovering requirements in such...

The Medforist Eumedis project concerns the implementation of a euro-Mediterranean network for sharing IST learning resources. Within this framework, a survey on competencies and training has been conducted. This paper presents the main results of the MEDFORIST survey. The survey has targeted mainly small and medium enterprises (SMEs) operating in different sectors in 11 countries of the Mediterranean region. Algeria, Cyprus, Egypt, Jordan, Lebanon, Malta, Morocco, Palestine, Syria, Turkey...

The challenges that learners with special need face in the course of learning are enormous. These challenges pose crucial problems to the teachers who are in direct contact with these types of learners. It is on this note that this study is undertaken to find out empirically the teachers' attitudes toward the education of learners with special needs. The study adopted the survey design using the simple random sampling to select 150 respondents to form the sample for the study. Frequency...

The aim of the paper is to present an experience about the implementation of E-Learning at Al-Quds Open University (QOU) - Palestine and at the Lebanese University (LU) and to describe particularly their experience within the framework of the Avicenna project. This paper will also focus on two points, which seem important to us, as this is the first experience of E-learning in our universities: o Copyrights /Author rights contracts: specific clauses. o Pedagogical model developed for...

Knowledge is a foundation of nation building. The discipline of knowledge management has become a hot topic in business because of its prospects for dramatic improvement in organizational effectiveness. Higher education institutions are in the knowledge business, since they are involved in knowledge creation and dissemination and learning. This paper is an attempt to examine the applicability of the concepts of knowledge management to higher education institutions in the Sudan. Identifies a...
