Climate is an essential part of crop production, determining the suitability of a given region for deciduous fruit products such as apples (Malus domestica). It influences the yield and quality of fruits. There is strong evidence of global and regional-scale climate change since the advent of the industrial era. In South Africa, mean surface temperatures have revealed a warming trend over the last century. This study aimed to assess the impact of climate change on temperature and chill unit...

Reducing vulnerability to climate change and enhancing the long-term coping capacities of rural or urban settlements to negative climate change impacts have become urgent issues in developing countries. Developing countries do not have the means to cope with climate hazards and their economies are highly dependent on climate-sensitive sectors such as agriculture, water, and coastal zones. Like most countries in Southern Africa, Zimbabwe suffers from climate-induced disasters. Therefore, this...

Background Paleoanthropological research focus still devotes most resources to areas generally known to be fossil rich instead of a strategy that first maps and identifies possible fossil sites in a given region. This leads to the paradoxical task of planning paleontological campaigns without knowing the true extent and likely potential of each fossil site and, hence, how to optimize the investment of time and resources. Yet to answer key questions in hominin evolution, paleoanthropologists...

The purpose the present study is to explore African American undergraduate students' perceptions of their experiences and academic motivation within a Historically Black College or University (HBCU) learning environment. As part of a larger study, we collected 212 open-ended survey responses from first year students in STEM majors about how the HBCU context shapes their academic motivation. We used semantic thematic data analysis and found three major themes and corresponding sub themes that...

The present study examines the effect of a technology-based assessment on the writing performance of Algerian English Foreign Language (EFL) students. Forty-two first-year EFL at the English Department at Tlemcen University (Algeria) took part in the experiment. They were divided into an experimental group (n = 21) and a control group (n = 21). A pre-test and a post-test were used as research instruments before and after the administration of the treatment, respectively. The data were...

Public secondary schools in Nigeria occupy a significant position for providing qualitative education, yet there has been increasing public discontent with the quality of students being produced in the country’s public secondary schools. Teachers are regarded as one of the resources necessary for achieving the goals of secondary education. It is against this backdrop that this study examined teachers’ collective efficacy as a predictor of students’ academic performance in North Central...

This study aims to analyse and compare the challenges and opportunities that refugees and asylum seekers experience in Sweden and South Africa along with the strategies they develop in relation to higher education. As both countries have undertaken a more restrictive refugee and asylum policy, this study hopes to contribute to the debate of inclusion and its challenges. The data-collection entails interviews focusing on inclusion through access to higher education. In exploring higher...

Abstract In this study, we modelled the current and future distribution of the V. tortilis subsp. raddiana var. raddiana for the period from 2050 (RCP 2.6; RCP 4.5; RCP 8.5) to 2070 (RCP 2.6; RCP 4.5; RCP 8.5) using a maximum entropy (MaxEnt) species distribution model. Our results showed that the precipitation‐associated variables had the strongest effect on the distributions of this species. Among these variables, the precipitation of driest quarter (Bio17: 31.9 of percentage contribution)...

The purpose of this study is to investigate young African American male students’ perceptions of misbehavior and teacher discipline. The study took place in a large southwestern metropolitan area of the United States. All of the participants attended the same K-8 charter school and were selected using high frequency teacher nomination of student misbehavior. Using tenants of sociocultural theory and symbolic interactionism as theoretical frameworks, moment to moment teacher-student micro...

South Africa has been classified as one of the most homicidal, violent, and dangerous places across the globe. However, the two elements that pushed South Africa high in the crime rank are the rates of social violence and homicide. It was reported by Business Insider that South Africa is among the most top 15 ferocious nations on earth. By 1995, South Africa was rated the second highest in terms of murder. However, the crime rate has reduced for some years and suddenly rose again in recent...

This study evaluated the prevalence of Entamoeba histolytica using microscopic detection and confirmed by DNA analysis using polymerase chain reaction (PCR) technique by taking samples of some public primary school pupils within Bwari Area Council of Abuja, Nigeria. Microscopic and polymerase chain reaction-restriction fragment length polymorphism analysis targeting only a small portion (228 bp) of the adh112 gene. Results showed that out of three hundred and twenty (320) stool sample...

Background: Fruit and vegetable consumption is an important source of nutrients for healthy growth and development, as well as a protective factor against chronic non-communicable diseases. Paucity of data exists on adolescents’ fruit and vegetable consumption in Ghana. This study, therefore, sought to determine the prevalence and correlates of fruit and vegetable consumption among in-school adolescents in Ghana. Methods: Data for this study were extracted from the 2012 Global School-Based...

Abstract Background Bread wheat ( Triticum aestivum L.) is a valuable commodity crop for local, regional and global markets. In Ethiopia, wheat ranks third after maize ( Zea mays L.) and tef ( Eragrostis tef Zucc.) in terms of total production, and fourth after maize, tef and sorghum ( Sorghum bicolor L.) in areas of cultivation. The major wheat-producing areas are mainly found in the mid-altitude (1900 to 2300 m above sea level) and high-altitude (2300 to 2700 m above sea level) regions of...

ABSTRACT This study sought to explore teaching and learning of accounting: in-service educators’ experiences in the context of a South African University. The study employs a qualitative research approach using a case study design. Ten accounting teachers were purposively selected. The findings revealed that accounting resources used for teaching and learning of accounting were not related to an accountancy education. Also, some accounting lecturers at university were found to be...

Research has increasingly recognized the adverse effects of perceived discrimination on the academic outcomes of children and adolescents from ethnic and racial minority backgrounds. However, little is known about the association between perceived discrimination and the motivation of ethnic minority students to pursue higher education. Guided by an academic resilience framework, the current study examined the relationship between perceived discrimination and two types of motivation to pursue...

Abstract Background The quality of malaria test results is crucial for optimal patient treatment and care. The Ghana Health Service is successfully shifting from presumptive clinical diagnosis and treatment of malaria to the Test, Treat and Track (T3) initiative. In line with the initiative, the National Malaria Control Programme (NMCP) set out to improve the capacity of medical laboratory professionals in Ghana through a five-day Malaria Diagnostic Refresher Training (MDRT) to build...

Guus van Westen shows how worldwide food production is increasingly organised in global value chains, linking producers, traders, processors and consumers in distant localities. Inserting smallholders in poor countries into corporate value chains by means of inclusive business models has become a major development strategy, aiming not just for just and sustainable agricultural growth, but even for further goals such as food security. While outcomes in terms of incomes can be positive, there...
