Early age at first sexual practice is a public health issue and now common around the world especially in the developing countries. The development of effective strategies to reduce the adverse consequences of early sexual initiation becomes real when sufficient data is available. Therefore, this study is aimed at assessing the prevalence and factors associated to early sexual initiation among college students in southwest Ethiopia.A cross-sectional study was conducted among 453 college...

This study was examined secondary school teachers’ instructional practices by using First Principle of Instruction model as guiding principle. Both qualitative and quantitative methods were employed. The total populations of the study were 52. From these 40 Biology teachers, 4 directors, 4 supervisors and 4 department heads were selected through comprehensive sampling technique. Data were obtained through questionnaire, interview, classroom observation and document analysis. Various...

This research study evaluated the projected future climate and anticipated impacts on water-linked sectors on the transboundary Limpopo River Basin (LRB) with a focus on South Africa. Streamflow was simulated from two CORDEX-Africa regional climate models (RCMs) forced by the 5th phase of the Coupled Model Inter-Comparison Project (CMIP5) Global Climate Models (GCMs), namely, the CanESM2m and IPSL-CM5A-MR climate models. Three climate projection time intervals were considered spanning from...

Student conflicts in secondary schools are one of the most common challenges faced in the 21st century in the modern world. Kenya has faced several incidents of student conflicts in Secondary schools mainly attributed to the cases of indiscipline and conflicts among students in the schools. In Kericho County, several incidences of student conflicts have been witnessed in the different schools, which have caused widespread material losses and other social impacts. The Specific objective was...

ABSTRACT The Mw 7.5 earthquake that struck central Papua New Guinea in 2018 was the largest event ever recorded in the region with modern seismic instruments. The ground motions associated with this event also triggered widespread landslides and affected more than 500,000 people. However, due to the absence of a local seismic and Global Positioning System network in the vicinity, the fault location, system, and slip distribution of this earthquake are not well documented. In this study, we...

Abstract Countries across Africa continue to face major challenges in education. In this review, we examine 145 recent empirical studies (from 2014 onward) on how to increase access to and improve the quality of education across the continent, specifically examining how these studies update previous research findings. We find that 64% of the studies evaluate government-implemented programs, 36% include detailed cost analysis and 35% evaluate multiple treatment arms. We identify several areas...

Abstract Global climate models struggle to simulate both the convection and cloud ice fundamental to lightning formation. We use the first convection‐permitting, future climate simulations for the lightning hot spot of Africa, at the same time utilizing an ice‐based lightning parametrization. Both the model and observations show that lightning over Africa's drier areas, as well as the moist Congo, have more lightning per rainfall than other regions. Contrary to results in the literature, the...

Abstract Cassava and sweetpotato are major factors in food security across sub-Saharan Africa. Though cassava and sweetpotato varieties that are early maturing and resistant to diseases have been developed, many farmers still grow local varieties. Cassava and sweetpotato cultivars that mature between 6 and 12 and 3 and 4 months after planting, respectively, are available. The objective of the synthesis was to obtain a general overview of cassava and sweetpotato production in Matiliku...

The impact of education on individual earnings has not been adequately discussed in the Sudanese literature. This paper estimates the rate of return on education by modeling individual-level Sudanese survey data for 2019. The importance of these data lies in the fact that they represent the period of Islamist rule in Sudan, which spanned thirty years and ended in April 2019 as a result of a peaceful youth popular revolution. A secondary aim is to trace how demographic characteristics...

Abstract Background Globally, the leading cause of years lived with disability is low back pain (LBP). Chronic low back pain (CLBP) is responsible for most of the cost and disability associated with LBP. This is more devastating in low income countries, particularly in rural Nigeria with one of the greatest global burdens of LBP. No Igbo back pain specific measure captures remunerative or non-remunerative work outcomes. Disability measurement using these tools may not fully explain...

This study was conducted to find out if the selected courses at the University of Botswana that have been prepared to meet the compliance standards of the Botswana Qualifications Authority (BQA) have any effects on teaching, learning and assessment processes with respect to the use of lesson outcomes. The study was guided by three research questions and these were: (1) What is the difference between lesson (or learning) outcomes and lesson objectives? (2) How are learning outcomes used in...

An efficient and credible approach to road traffic management and prediction is a crucial aspect in the Intelligent Transportation Systems (ITS). It can strongly influence the development of road structures and projects. It is also essential for route planning and traffic regulations. In this paper, we propose a hybrid model that combines extreme learning machine (ELM) and ensemble-based techniques to predict the future hourly traffic of a road section in Tangier, a city in the north of...

هدفت الدراسة الحالية إلى معرفة دور كبار السن في تعزيز الشعور بالتفاؤل، والسعادة لدى أولادهم من طلبة الجامعات الفلسطينية، وفقا لمتغيرات (الجنس، المستوى الدراسي، الحالة الصحية للوالد والوالدة). وتكون مجتمع الدراسة من طلبة الجامعات الفلسطينية التالية: (جامعة الخليل، بوليتكنك فلسطين، القدس المفتوحة/فرع الخليل)، والبالغ عددهم (18361) طالبا وطالبة، ولتحقيق أهداف الدراسة أختير منهم عينة قصدية بلغ قوامها (500) طالب وطالبة، وطبق عليهم مقياس التفاؤل من إعداد الباحثين، وقائمة اكسفورد للسعادة (OHI)....

Abstract Background Sexual risk behaviours that occur among young men are based on dominant notions and practices that prevail in cultural contexts. As such, understanding the intersection of cultural norms and sexual risk behaviours among young men is very important. Methods The study used a qualitative design and conducted four focus group discussions with 36 male students who were purposively selected from different levels of study at the University of KwaZulu-Natal. Data were analysed...

The free senior high school policy is one of best social and economic intervention policies that openly affect both parents and senior high school students. Parents and guardians especially, have been left off the hook of their economic and financial burden. This study therefore looks at the effect of introducing the free senior high school policy on the economic and social lives of parents and students respectively. Data were obtained from three hundred and thirty six (336) participants. A...
