To evaluate the status of teaching of repair of defective resin-based composite restorations in dental schools in the Middle Eastern and North African (MENA) countries.A validated 14-item questionnaire was mailed to the directors of the operative/restorative dentistry department in 40 MENA dental schools. Data were collected on teaching, including whether the repair of resin-based composite restorations was part of the dental school curriculum; the rationale behind the teaching; how...

The teaching of Public International Law (PIL) in African law schools is backward. While Article 13 of the International Covenant on Economic, Social and Cultural Rights demands that, for education to be acceptable, it must also be culturally appropriate, the teaching of PIL in our schools is largely only reflective of European westernisation. This study reviews relevant literature in law, sociology, international relations, history and politics, and rely on surveys on PIL syllabi in select...

This study examined access to information and communication technologies (ICTs) and use of electronic library resources (ELRs) in a rural-based university, against the backdrop of ongoing changes in the way people access information. It aimed to investigate access to ICTs and use of ELRs at the University of Venda in South Africa (SA). A quantitative research approach with an embedded survey research design was adapted to collect data from the respondents. Stratified sampling techniques were...

Abstract Objective Despite getting sufficient sleep being one of the most important things that we can do to keep our body and mind healthy, sleep deprivation has become a major public health concern. This study aimed to determine the prevalence of sleep deprivation and its associated factors among students of the Institute of Health in Jimma University. Methods An institution-based cross-sectional study was conducted from April 10 to April 24 in 2019. Data were collected from 365 randomly...

There has been an increasingly well-documented, rapid rise in tobacco production over the last couple of decades in Mazowe, Zimbabwe, despite growing public health concerns about lung cancer and nicotine’s addictive capacities in the wealthier countries of the West – even affecting the South African market. This has been accompanied by a shift away from its production almost completely on large-scale farms towards predominantly small-scale farms. To date, less consideration has been given to...

Compositions of clinopyroxenes and spinels from the ocean/continent boundary of the Cameroon Line are presented. The spinels occur as minute inclusions in olivine phenocrysts from alkali basaltic bombs collected from the Debunscha maar deposit at the foot of Mt Cameroon. The inclusions are mostly subhedral to euhedral in shape, measuring generally less than 70 μm in diameter. The studied spinels are chemically characterized by: Fe 2+ /(Fe 2+ +Mg) = 0.47–0.64, Fe 3+ /(Fe 3+ +Al+Cr) =...

In Tanzania, adolescent pregnancy results in a denial of the girl's fundamental right to education. School expulsion of pregnant adolescents is a common practice exercised by teachers in this country for decades. This study aimed to explore the perceptions and feelings of secondary school teachers towards this practice.The study used a qualitative approach comprising focus groups and individual semistructured interviews with a purposive sample of sixteen teachers and nine headmasters (n =...

The study was designed to investigate the constraints to the effective discipline of secondary school students in Awka South Local Government Area of Anambra state. The survey design was adopted for the study. Five research questions guided the study. The population of the study comprised 1320 teachers. A simple random sampling technique was used to select 150 respondents for the study. The instrument for data collection was a structured questionnaire titled “Constraints to Effective...

This study interrogated the prevalence and effectiveness of teaching methods on students’ academic performance in Civic Education in Calabar Metropolis of Cross River State, Nigeria. It was directed by two research questions and one hypothesis. The design used was quasi-experimental. The population of the study comprised all Senior School two (SS2) students (3,193 in number) in the 23 public secondary schools in the area in 2018/2019 academic year. Purposive sampling technique was employed...

For three decades, numerous South African scholars have researched the efficacy of access programmes in providing alternative pathways to careers in Science, Technology, Engineering and Mathematics through foundation provisioning. In light of this, Extended Curriculum Programmes (ECPs) were designed for talented Black students who could not gain access to tertiary studies due to poor schooling conditions caused by apartheid. As scarce skills programmes that receive dedicated funding from...

The larger study that has influenced this article was designed to explore what influenced rural men’s capabilities to actively participate in children’s early social development and its impact on transition to adulthood among their university-going children. Studies have established an increase in the level at which fathers in South Africa have been found wanting in terms of supporting their children’s development at early stages in their lives. It has been reported that this unacceptable...

<h2>Abstract</h2> There is evidence that Nigeria is already experiencing environmental challenges attributed to climate change (CC) and its impacts. This has clearly highlighted the need for knowledge-based strategies to help plan adequate mitigation and adaptation measures for the country. One of the basic requirements to ensure such strategies is the development of a database of national CC research. This will aid in the assessment of past and present scientific publications from which...

• Electricity fraud detection in conventional meters. • Combining ML : supervised and unsupervised algorithms. • Extensive feature engineering. • Multivariate Gaussian distribution for anomaly detection . • Light Gradient Boosting algorithm: performance and tuning. Although fraud in electricity consumption is easier to detect when consumption is recorded hourly by smart meters, in most developing countries, where the propensity for fraud is higher, conventional meters are not yet affordable....

In Nigeria, the threat posed by climate change is leading policymakers and the media to frame climate change as a security threat that warrants support for adaptive actions. We draw upon securitization theory to examine how security narratives affect climate change adaptation. Using primary and secondary data, we find that although securitization arguments are easily identified in climate change policies and action plans in Nigeria, the implications of securitization for adaptation policy...

Weather and climate extremes affect food crop production of women farmers in sub-Saharan Africa. Women farmers use specific adaptation strategies to respond to weather and climate extremes confronting them. Most studies on the role of gender in the uptake of adaptation strategies have focused on gender differentiation and the ex-ante adaptation strategies that women farmers in Ghana use to respond to climate extremes. The aim of the present study is to analyze the ex-post targeted strategies...
