Abstract The genetic heterogeneity of congenital hearing disorders makes molecular diagnosis expensive and time‐consuming using conventional techniques such as Sanger sequencing of DNA. In order to design an appropriate strategy of molecular diagnosis in the Algerian population, we explored the diversity of the involved mutations by studying 65 families affected by autosomal recessive forms of nonsyndromic hearing impairment (DFNB forms), which are the most prevalent early onset forms. We...

Researchers agree that information resources are imperative for curriculum support. Equitable access to information resources by teachers and learners is absolutely essential to enable them to execute their curriculum-related tasks. However, only a few schools have functional libraries in South Africa making accessibility to the information resources a major challenge to the majority of the teachers and learners. Where school libraries are inadequate, other information services become...

This paper aimed at assessing the impact of baryte mining on land pollution in Azara, Nigeria. Two barytes mining sites were selected; Vein 2 and Vein 17. Measurements and observations were carried out to indentify the impact of baryte on land pollution in the area. The findings revealed that areas of about 77226m 2 and 132096m 2 were devastated in Vein 2 and Vein 17 respectively. The Findings also revealed that rain-fed farming, grazing and mining were the major land uses in the area with...

The negative effect of Climate Change (CC) on agriculture across Africa has been well established and hence the global policy interest. In Nigeria, crop farming is climate dependent and farmholders often employ measures that are sub-optimal against adverse conditions of climate. This raises the vulnerability of farming to CC uncertainty. For a long time, knowledge of CC perception by farmholders dominated the existing literature. The study employed econometric techniques to generate...

This research was carried out to examine suitability of the regular school curriculum to learners with disabilities in inclusive classrooms in Kisumu County in Kenya. It has been observed that teachers teaching in inclusive classrooms encounter problems in trying to adapt the curriculum content to accommodate all learners since they respond differently. Although education systems the world over have for long provided special education and related services to students with disabilities in...

With only about 6 million people, Papua New Guinea has over 800 separate languages, more than any other country. Until recently, English was the only language of formal education. At the end of the 1990s the national government initiated an educational reform mandating that the language of kindergarten through Grade 2 be in a “language of the community”. This chapter looks at the example of the challenge of establishing a school in the Nalik language of New Ireland Province. While the change...

Human Resources (HR) and information technology are the two elements that many firms are learning to use as strategic weapons to compete.The vision 2030 economic reform progress initiated by the government of Kenya is aimed at turning Kenya into a middle level income country.It incorporates ICT as a social economic force under the economic pillar for driving development among other sectors.The government's key objective is to turn Kenya into a global ICT hub and a premier location for...

While it is generally accepted that Human resource plays an important role in organizations, organizations now take cognizance of the fact that the more strategic the approach to human resource management (HRM), the greater the contribution of HRM to organizational performance.This is because HRM powerfully impacts on the policies, practices and systems that influence employees' behavior, attitude and performance The purpose of this study is to investigate the factors affecting the adoption...

Stress impacts negatively and positively depending on how effectively the individual experiencing the phenomenon is able to cope. The objective of this study was to identify the stressors in clinical practice for nursing students and the coping mechanisms used. Eighty-nine (89) students from the Department of Nursing, KNUST were selected using systematic sampling methods. Respondents completed questionnaires, part of which was the Perceived Stress Scale (PSS). Data was analyzed using...

Adverse climate impacts are already evident across Southern Africa and pose a serious threat to the development prospects of the region's societies. Sustainable development in this region will depend on the rapid development and implementation of effective adaptation measures. This volume identifies the new socioeconomic and political boundaries to development that result from ongoing climate change in Southern Africa. The collected papers explore the region's potential for a transition to...

Sub-Saharan Africa is particularly vulnerable to climate change. Multiple biophysical, political, and socioeconomic stresses interact to increase the region’s susceptibility and constrain its adaptive capacity. Climate change is commonly recognized as a major issue likely to have negative consequences on food security and livelihoods in the region. This paper reviews three bodies of scholarship that have evolved somewhat separately, yet are inherently interconnected: climate change impacts,...
