Substance use is a global health issue that may lead to engagement in other risky behaviours, addiction, accidents and non-communicable diseases. In Nigeria, this risky behaviour is becoming an emerging trend among secondary school students. This review was thus carried out to gain an overview of the prevalence and risk factors of substance use among secondary school students in Nigeria. A literature search of articles in Scopus, PubMed and other online databases was conducted for articles...

Long-term urban land use land cover change (LULCC) dynamics and climate change trends in Southwest Ethiopia's four urban centers were examined for 60 years. Remote sensing, aerial photos, and Landsat, temperature, and rainfall data were analyzed from a climate change perspective over the Jimma, Bedelle, Bonga, and Sokorru urban centers of southwest Ethiopia from 1953 to 2018. Based on geospatial analysis and maximum likelihood supervised image classification techniques to classify LULCC...

Abstract Satellites allow large‐scale surveys to be conducted in short time periods with repeat surveys possible at intervals of <24 h. Very‐high‐resolution satellite imagery has been successfully used to detect and count a number of wildlife species in open, homogeneous landscapes and seascapes where target animals have a strong contrast with their environment. However, no research to date has detected animals in complex heterogeneous environments or detected elephants from space using...

INTRODUCTION. As highlighted in the 2018 Uganda Education Response Plan, reading levels in refugee host communities are way below the national average. Since the 2018 National Assessment of Progress in Education report highlighted some challenging areas to the in-service teachers, a possible explanation for the persistent poor performance of learners in reading may reside with the finding that many educators themselves lack an understanding of the linguistic construct. Therefore, an informed...

Land cover and climate changes greatly influence hydrologic responses of a basin. However, the response vary from basin to basin depending on the nature and severity of the changes and basin characteristics. Moreover, the combined impacts of the changes affect hydrologic responses of a basin in an offsetting or synergistic manner. This study quantified the separate and combined impacts, and the relative contributions of land cover and climate changes on multiple hydrological regimes (i.e.,...

The Botswana higher education system has been producing low-quality unemployable graduates and the low levels of learner motivation is believed to be a major factor. Premised on the Self-Determination Theory, the purpose of this study was to explore the nexus between pedagogical strategies and motivation of hospitality management learners in a selected higher education institution in Botswana. A descriptive survey design was adopted while the quantitative methodology was employed....

Alcohol use and cigarette smoking among in-school youth remain a major public health problem globally. However, data on the prevalence of the use of these substances and associated factors are limited in sub Saharan Africa, including South Africa. The objectives of this study were to determine the prevalence of cigarette smoking and alcohol consumption, as well as associated factors, among high school learners in a township in Pretoria, South Africa. A cross sectional survey was used to...

Digital media has ushered in a new era of awareness and advocacy on the rights of people with disabilities. In the absence of personal experience and contact, digital media plays a considerable role in shaping knowledge and attitudes towards disability, especially since traditional media has long neglected to represent the realities of disabled populations. Where there is a space for disability issues, it is often centered in models of charity and ableism. Mainstream media has failed to...

This book disseminates original research on learning in and from practice in pre-service teacher education. Authors such as Lederman and Lederman describe the student teaching practicum (or work-integrated learning [WIL]), which is an essential component of pre-service teacher education, as the ‘elephant in the room’. These authors note that 'the capstone experience in any teacher education programme is the student teaching practicum… [a]fter all, this is where the rubber hits the road'....

The effect of attitude as a psychological construct that impacts students achievement in secondary schools have been widely reported, and the need to address that non-cognitive trait, so as to improve students’ achievement have been stressed. Negative attitude of students have adversely affected educational outcomes and the need to improve this trait in students is the aim of this study. The study investigated the effect of the 7E instructional strategy on the overall attitude of students of...

Banana (Musa spp.), a perennial (sub-)tropical crop, suffers from seasonal droughts, which are typical of rain-fed agriculture. This study aimed at understanding the effect of seasonal drought on early growth, flowering and yield traits in bananas grown in the East African highlands. A field experiment was set up in North Tanzania using four genotypes from different geographical origins and two different ploidy levels. The treatments considered were exclusively rain-fed versus rain...

Abstract Despite widely documented shortfalls of teacher skills and effort, there is little systematic evidence of rates of teacher turnover in low-income countries. I investigated the incidence and consequences of teacher turnover in Rwandan public primary schools over the period from 2016 to 2019. I combined the universe of teacher placement records with student enrollment figures and school-average Primary Leaving Exam scores in a nationally representative sample of 259 schools. Results...

Objective: To validate the Social Media Disorder scale in Nigerian adolescents by determining its unidimensional structure, reliability, sensitivity, specificity, and criterion validity.Methods: A total of 516 and 1213 pre-university students in two universities were randomly recruited and assessed using the 9-item Social Media Scale and the 12-item General Health Questionnaire (in the second survey only).Results: 46.3% and 56.3% of respondents in the first and second surveys met the...

<ns3:p>The increase in health research in sub-Saharan Africa (SSA) has led to a high demand for biostatisticians to develop study designs, contribute and apply statistical methods in data analyses. Initiatives exist to address the dearth in statistical capacity and lack of local biostatisticians in SSA health projects. The Sub-Saharan African Consortium for Advanced Biostatistics (SSACAB) led by African institutions was initiated to improve biostatistical capacity according to the needs...

The quality and success of postgraduate education largely rely on effective supervision. Since its inception in 2008, the Consortium for Advanced Research Training in Africa (CARTA) has been at the forefront of providing training to both students and supervisors in the field of public and population health. However, there are few studies on supervisors' perceptions on effective doctoral supervision. We used a mostly descriptive study design to report CARTA-affiliated doctoral supervisors'...
