The present study examined how the Egyptian EFL students competently use the FL discourse markers. In other words, how the Egyptian EFL learners can properly differentiate between the syntactic and textual functions of such markers. Data were collected through the instruments of pretest and posttest. Eighty Egyptian EFL students enrolled at the Department of Languages and Translation, Higher Institute for Specific Studies, Haram participated in the present study. They were divided into a...

Promoting a person-centred workplace culture in organisations is one of the most challenging tasks for both employers and employees. Person-centred workplace cultures and effective teamwork have been linked to achieving optimal organisational outcomes. We report nurse educators' perceptions of the elements required for effective teamwork to promote a person-centred workplace culture in a public nursing education institution in South Africa. A consensus meeting with 32 participants,...

The impact of hazards on population groups has always been different, depending on the social and environmental factors of the impacted people. An enhanced understanding of what influences people's susceptibility to hazards, how and why, is a prerequisite for designing mitigation plans, prioritizing resources for preparedness and formulating an appropriate adaptation strategy. This study therefore, assessed the geographic variation of social vulnerability to natural hazards in Zimbabwe. It...

Municipal Solid Waste (MSW) is composed of items that are discarded or disposed of daily including paper, plastics, glass, metals, used gadgets, paint and old furniture.The plastic waste stream has proven to be problematic to manage sustainably on a global scale.Various researchers are trying to come up with innovative ways of alleviating the detrimental effects of plastic on the environment.Examples include the production of liquid fuel and synthetic gas through pyrolysis and gasification...

Universities have an integral role in the development of communities. This is underpinned by the notion that universities possess a social responsibility to be agents of change in relation to society’s socio-economic, political, and environmental issues. In Africa, the quest for sustainable development necessarily engages a consideration of the different forms of knowledge available. This is as a result of the rich and varied patterns of beliefs, behaviour, and values that permeate the...

A common concern with efforts to directly help some small businesses to grow is that their growth comes at the expense of their unassisted competitors. We test this possibility using a two-stage randomized experiment in Kenya that randomizes business training at the market level and then within markets to selected businesses. Three years after training, the treated businesses are selling more, earn higher profits, and their owners have higher well-being. Point estimates of the spillovers on...

Technology is almost indispensable in general life, and it is constantly evolving. Therefore, it is important to determine how these advances can be of benefit in teaching and learning. ICTs and social media for educational purposes is a notion not only fraught with challenges but also offering much-untapped potential. Web 2.0 technologies and electronic teaching aids can be used to greatly advance the transmission of knowledge in the school setting. The investigation at hand attempted to go...

Universal salt iodization has been adopted by many countries to address iodine deficiency. More recently, salt-reduction strategies have been widely implemented to meet global salt intake targets of <5 g/d. Compatibility of the two policies has yet to be demonstrated. This study compares urinary iodine excretion (UIE) according to 24-h urinary sodium excretion, between South Africa (SA) and Ghana; both countries have implemented universal salt iodization, but in Ghana no salt-reduction...

Abstract High‐resolution numerical weather prediction (NWP) simulations of heavy rainfall events are known to be strongly sensitive to the choice of the sub‐grid scale parameterisation schemes. In the African continent, studies on such a choice at the convective‐resolving scales are not numerous. By exploiting a state‐of‐the‐art NWP model, the Weather Research and Forecasting (WRF) model, the sensitivity of the simulation of three heavy rainfall events in Sub‐Saharan Africa to the...

Clinical teaching is essential for undergraduate nursing and midwifery students. Registered nurses/midwives trained as preceptors (an experienced nursing/midwifery professional who teaches, supervises and serves as a role model for a student), guide the students during clinical practices. Literature is scanty on the roles and experiences of the preceptors in Malawi. This study explored the roles and experiences of preceptors during clinical teaching of the students.A cross-sectional study...

The purpose is to improve the management of local government affair including the management of community health, free basic education and the management of contracts through public-private...

Evidence on the relationship between lifestyle, socio-economic factors and pesticide exposure and urinary concentrations of organophosphate (OP) pesticide metabolites among children is generally incomplete. This study investigated the relationship between socio-economic factors and reported pesticide exposures and the sum of three urinary concentrations of dialkyl phosphate metabolites (DAP) among boys living in the rural areas of the Western Cape, South Africa. Data was collected during a...

Introduction: Oral health is not only the absence of oral ailments and dysfunctions but also includes other components that influence a person's social life like satisfaction with one's dental appearance and beauty. This study was done to determine the self-perceived satisfaction with dental appearance and associated factors among secondary school students in Iringa, Tanzania. Methods: This descriptive cross-sectional study was done in the Kilolo district of the Iringa region on the southern...

Background: Staphylococcus aureus and Enterococcus species cause invasive infections such as bacteremia and infective endocarditis. Despite vancomycin being the drug of choice for drug-resistant infections caused by these species, few studies have been conducted to ascertain vancomycin resistance in the African setting. This is crucial given the rising resistance in these organisms. This study aimed to isolate S. aureus and Enterococcus species and determine their susceptibility to...
