Quantifying water contents in the lithospheric mantle is key to our understanding of global geodynamics, mantle composition, and related physical properties. Most mantle lithologies (peridotite) contain little water (~50 ppm), but petrological heterogeneities such as pyroxenites are more hydrous (~300 ppm) relative to the mantle rocks. Pyroxenites also melt at lower temperatures than peridotites and are thus important to magma genesis. Thus, quantifying pyroxenite water contents provides new...

This study was carried out to determine the e-learning competencies gap of business students in the North Central Polytechnic, Nigeria.To direct the study, two research questions guided the study and two null hypotheses were tested at 0.05 level of significance.The Cronbach Alpha coefficient measure of internal consistency was used to test the reliability value of the instrument.The results of the reliability test were 0.90, 0.91.The population of the study comprised 753 students of...

Teachers encounter many problems in the classroom and amongst is classroom management. Classroom management pose a problem to teachers especially the novice teachers who are not privileged to undergo the training of teaching profession. Teachers’ personality type play an important role in whether to increase positive behaviours or decrease negative behaviours among the students in classroom environment. This study therefore examined teachers’ personality type as determinant of classroom...

Ghana's susceptibility to climate change is well documented and the agricultural sector which is the backbone of the country's economy is one of the most vulnerable sectors to the adverse effects of climate change. This study employed both quantitative and qualitative research methods including household surveys and focus group discussions to examine the extent to which traditional agroecological knowledge is used to manage climate change in three selected communities (Gia, Gaani and...

Before implementing the Competency-Based Approach (CBA) in 2003, the Algerian educational system was based on traditional teaching methods that focused mainly on acquiring the knowledge about language delivered by the teacher and the amount of information the learner could accumulate to pass the exams. Although CBA has shifted the teacher’s role from a knowledge transmitter to a facilitator and the learner from a passive recipient to an active participant, the teacher-centered paradigm still...

The outbreak of COVID-19 has redefined how we carry out our daily activities with emphasis on safety measures like social distancing, the use of face masks and proper hygiene. With nursing personnel at the forefront of combating the menace created by this pandemic, the use of ICT has remained a vital technology that must be embraced by all in order to carry out a safe nursing practice. Therefore, becoming ICT compliant is no more an option to stay relevant and alive during this COVID era....

Background: The public health burden and prevalence of intestinal helminths in Nigeria are increasing, with 45% of school age children being infected annually. Interrogating the burden and associated demographics will aid preventive measures, early diagnosis and prompt treatment. Objective: The objective of the study was to determine the prevalence of intestinal helminthic infections in school children, types and associated sociodemographic characteristics. Methodology: This was a cross...

Background: Today, one of the most challenging duties of nursing school is achieving clinical practice proficiency. Emotional intelligence correlates with students’ clinical practice performance. Such data are scarce in Southwest Ethiopia. Therefore, this study aimed to examine the relationship between emotional intelligence and clinical performance of undergraduate nursing students during obstetrics and gynecology nursing practice. Methods: A cross-sectional study was employed. All...

Introduction: COVID-19 has been a global public health problem since December 2019.Higher education institutions are risky areas for the transmission of COVID-19.But, still there is insufficient information on the prevention of the disease in this setting.Objective: To assess knowledge, attitude, and prevention practices towards COVID-19 among students of Ethiopian higher education institutions.Methods: Institutin -based cross-sectional study design was conducted from December 1 to 30, 2020...

Gender-based violence (GBV) is a significant global public health problem and adversely impacts the physical and mental health of women. This study aimed to determine the consequences of GBV (including sexual, physical, emotional, and overall GBV) on female high school students in eastern Ethiopia. An institutional-based cross-sectional survey was conducted among 1,199 female high school students in eastern Ethiopia using a self-administered questionnaire. Descriptive statistics were...

Abstract Drought is a complex natural hazard that can occur in any climate and affect every aspect of society. To better prepare and mitigate the impacts of drought, various indicators can be applied to monitor and forecast its onset, intensity, and severity. Though widely used, little is known about the efficacy of these indicators which restricts their role in important decisions. Here, we provide the first validation of 11 commonly-used drought indicators by comparing them to pasture and...

I investigate the Kenyan government’s 2008 public secondary school expansion policy which lowered school fees and increased capacity. This policy rapidly increased the proportion of students continuing from primary to secondary school, particularly from areas with low initial primary to secondary transition rates. Using this regional variation in exposure to the program together with birth-cohort variation, I show that the program increased female educational achievement, delayed childbirth...

The World Health Organization has been making recommendations on assessing and monitoring air quality for human health protection. Its implementation implies a spatial distribution plan for air quality monitoring sites, especially in populated cities where high emissions of air pollutants with anthropogenic origin are observed. Therefore, the present study aimed: (i) to propose the spatial distribution of air quality monitoring sites in the city of Luanda (capital of Angola); and (ii) to...

The Canary Current is a potential hotspot for climate change impacts on the oceans where 63 million people depend upon marine resources for national economies and livelihoods. Their unique vulnerability highlights the key roles of climate services and capacity building in order to develop effective adaptation measures. The Canary Current is a potential hotspot for climate change impacts on the oceans where 63 million people depend upon marine resources for national economies and livelihoods....

This study adopted quasi experimental design. Pretest, posttest experimental and control groups design was adopted. Two research questions and two hypotheses formulated and tested at 0.05 level significance. The population for the study comprises of 3395 senior secondary school chemistry students in Minna metropolis, Niger state. A multi-stage sampling technique was employed, which were clustered into A &B with a sample size of 120. Four schools were randomly sampled. Balancing of Chemical...

Globally, the need to mitigate the spread of Covid-19 had rendered the traditional face-to-face educational delivery systems of Higher Education (HE) irrelevant. In light of that, institutions of HE had abruptly introduced online teaching platforms as an alternative, though without auditing the lecturers’ capacities and skills. Informed by the Appreciative Inquiry Model (AIM), this interpretive case study used virtual meetings and WhatsApp discussions to explore the professional limitations...

The application of land use regression (LUR) modeling for estimating air pollution exposure has been used only rarely in sub-Saharan Africa (SSA). This is generally due to a lack of air quality monitoring networks in the region. Low cost air quality sensors developed locally in sub-Saharan Africa presents a sustainable operating mechanism that may help generate the air monitoring data needed for exposure estimation of air pollution with LUR models. The primary objective of our study is to...

The chapters of the IFCN, Asia Oceania (AOC), Europe Middle East and Africa, (EMEAC), Latin America (LAC), and North America (NAC), have cooperated to undertake, for the first time, a survey of training and education practice in their national societies. The results have been pooled so that data on aspects of our practice may now be compared and contrasted. The survey looked at the status of clinical neurophysiology, (mono- or subspecialty) within countries, training duration, numbers of...
