The easing of COVID-19 restrictions in southern Africa, including Zimbabwe, has seen most countries reopening schools for face-to-face learning. In this letter we discuss the paradox of reopening schools in the COVID-19 era and proffer recommendations for safe learning environments.

Today, the threat of crude oil pollution globally, has been a resounding epoch of ecosystem degradation. This affects the lives of flora and fauna in the ecosystem as well as influence the human's economic needs. The aim of this study is to assess the heavy metals and petroleum hydrocarbons concentrations (crude oil pollutants) in agricultural soils of selected communities in Niger-Delta region. Models were used to assess the crude oil pollution loads and its source apportionment. The...

Despite the fact that quality and effective services are provided to meet adolescents' needs, the perceptions of parents regarding the delivery of these services must be taken into consideration. This aim of this study was to explore the perceptions of parents of High school students on the sexual and reproductive needs of adolescents.The study employed an exploratory research design using a qualitative approach.Participants were selected using purposive sampling technique and a total number...

The condition of being overweight is the abnormal excessive accumulation of fat in the body. Globally, it is a serious public health issue in both developing and developed countries.This study aims to identify determinants of overweight among primary school children in Arba Minch town, Southern Ethiopia, 2021.A school-based unmatched case control study was conducted from June 20 to 30, 2021. The total sample size was 285 (95 cases and 190 controls). Multistage sampling technique was used....

The earthquake magnitude data for Sudan Territory includes four types of magnitude scales (Moment Magnitude Mw, Surface wave magnitude Ms, Local magnitude ML and Body wave Magnitude mb). Unifying the magnitude scale of the compiled earthquake catalogue requires converting these scales to one appropriate scale, usually moment magnitude scale. Therefore, the current paper is presented to retrieve plausible magnitude regression relationships for Sudan Territory. For this reason, all earthquakes...

This study identified and determined the concentration of heavy metal contaminants in Igun, Ijana-Gada and Igbadae gold mining sites using Particle Induced X-ray Emission (PIXE) technique. This was with a view to providing information on various heavy metal concentrations, potential sources of metals contamination and pollution load at Igun, Ijana-Gada and Igbadae gold mining sites. A total of thirty soil samples were collected randomly from Igun, Ijana-Gada and Igbadae gold mining sites in...

Reservoir petrophysical characterization involving permeability estimation in the laboratory using core samples is time-consuming and that too accords limited coverage of the sub-surface reservoir. Machine learning (ML) algorithms have been utilized to overcome such difficulties, which offers better and more accurate prediction models. This work integrates core data and ML approached and reports a comprehensive petrophysical evaluation of the Cenomanian Bahariya and Albian Kharita reservoirs...

The Grand Saloum is characterized by a vast coastal plain cut by a dense hydrographic network and populated by mangrove plant formations. It is an ecosystem of capital importance in view of its ecological, socio-economic and environmental role. However, the Saloum delta remains a complex and very sensitive environment, particularly in the context of climate change. It therefore deserves special attention for better conservation. The objective of this study is to analyze the spatiotemporal...

The study examined the views of lecturers and Peer Assisted Learning (PAL) Tutors on students' use of smartphones for learning at a rural university in the Eastern Cape Province of South Africa.The research adopted a quantitative approach and the design was a survey.A total sample of 50 academics that was comprised of 39 lecturers from the Faculty of Business Science & Management and Faculty of Science, Engineering & Technology from a population of 71 and 11 PAL Tutors from Faculty of...

Children in Sub-Saharan Africa spend a non-trivial amount of their time cooking and collecting fuel for domestic use. This is particularly the case in rural areas where access to efficient energy is low, and children’s academic performance is poor. This paper argues that households' use of cooking gas could reduce the time spent doing domestic chores, increase learning time, and improve children's school performance. We investigate this proposition using the Ghana Living Standards Survey...

Out-of-school nomadic children are at the risk of demonstrating low critical thinking skills and disposition because of a number of reasons-they lack access to formal education, their parents are largely illiterate, they associate mainly with children in their category. This study was conducted to determine if interactive television instruction will be effective in improving the critical thinking skills and propensity of out-of-school nomadic children. The researchers applied...

<h2>Abstract</h2><h3>Background</h3> Vaginal birth after caesarean section is appropriate for a majority of women who have had a single prior lower segment caesarean section. However, little is known about vaginal birth after caesarean section in Ethiopia. Thus, this study aimed to assess the success rate of vaginal birth after caesarean section and its associated factors in Mizan-Tepi University Teaching Hospital, southwest Ethiopia in 2020. <h3>Methods</h3> An institutional-based...

Egypt is one of the hottest countries in the world, and extreme climate events are becoming more frequent, which is consistent with the warming of the planet. The impact of this warming on ecosystems is severe, including on livestock production systems. Under Egyptian conditions, livestock already suffer heat stress periods in summer. The predicted increases in temperature as result of climate change will affect livestock production by reducing growth and milk production because of appetite...

A contentious debate in academic as well as policy circles relates to the growth in private schooling in the Global South. While proponents highlight the superior learning outcomes of pupils in private schools, others have argued that this is merely a reflection of the more advantaged family background of private school pupils, rather than an effect of private schooling itself. We contribute to this debate by providing estimates derived from household fixed-effect models, which control for...

The United States’ Farm-To-School Program (F2SP) is a competitive grant program that targets participants of the National School Lunch Program and School Breakfast Program with the aim of increasing the quantity and frequency of locally sourced fruits and vegetables offered to children during the school year. This narrative review aims to summarize the outcomes of the F2SP’s interventions on child health and wellness using the research available to date and provide points to consider when...

Abstract While a growing literature studies the effects of climate change on international migration, still only relatively little is known about the individual mechanisms linking migration decisions to climate change. We argue that climate change literacy (i.e., knowledge about climate change) is a major determinant of why some individuals consider migrating to other countries in response to climate change effects. In particular, climate change literacy helps individuals translate their...
