Over the years, interpersonal communication among farmers has been identified as a way farmers share agricultural knowledge among themselves. During this process ideas are exchanged. In the face of inadequacy in the number of extension personnel in Nigeria, there is need to document the effectiveness of farmers’ knowledge exchange as an alternative channel of disseminating innovations. Hence, this study assessed the determinants of knowledge exchange on drought tolerant maize (DTMA)...

Background: Nigerian adolescents are faced with challenges around physical inactivity. Poor attitudes to, and practices in, physical activity during school physical education (PE) classes are also a challenge. Our study integrated an innovative PE teaching methodology (autonomous support style) into a professional development training (PDT) programme for teachers to promote PA among adolescents. The study aimed at determining the effects of this school-based physical activity intervention...

Abstract Background The evolution of cognitive impairment of vascular origin is increasingly becoming a prominent health threat particularly in this era where hypertension is the leading contributor of global disease burden and overall health loss. Hypertension is associated with the alteration of the cerebral microcirculation coupled by unfavorable vascular remodeling with consequential slowing of mental processing speed, reduced abstract reasoning, loss of linguistic abilities, and...

ODeL offers a lot of opportunities and unique challenges for adult learners. In this paper, the authors sought to examine the main problems that influence the effective teaching and learning of geography and environmental studies in Zimbabwe through ODeL as perceived by the students at the ZOU's Harare/Chitungwiza Regional Campus. This single case study employed vital informant semi-structured interviews, documentary analysis and observations to solicit information from ten students and four...

Current theories of teaching favour students-centred classrooms. In Literature-in-English lessons, active participation of students is essential for optimal learning. This study examined the level of students' active participation in Literature-in-English classrooms as the major reason for the high failure rates of Nigerian students who take this subject in the yearly senior secondary school examinations. The study was carried out in Ibadan metropolis, Oyo State. The mixed method research...

This article investigates the closing years of East–West Cold War rivalry by focussing on the inconsistent implementation of Mikhail Gorbachev’s policies of de-escalating decade-long regional conflicts across the globe.

Author(s): Bassi, Vittorio; Kahn, Matthew E.; Lozano Gracia, Nancy; Porzio, Tommaso; Sorin, Jeanne | Abstract: Developing countries suffer from rising urban pollution levels, with associated negative effects on health and worker productivity. We study how managers in developing country cities cope with the polluted environment. We collect high resolution pollution measurements within Ugandan cities and match these with a novel firm survey. We find that firms locate in close proximity to...

Performance target setting was introduced as a result of performance contracting which emanated from France in 1960’s. Escalation in environmental hurly-burly in the 1970’s, forced top managers to embrace performance target setting. Institution of performance target setting in Kenya lie beneath belief that output and cost decrease can lead to enhancement in service provision to Kenyans. The focus was on effect of performance target setting on performance of teachers in Londiani Sub-County...

An educational system that aspires to be effective would constantly strive to bring about positive change into the society and the students it is meant to serve. Attending school would amount to a waste of time unless the experience manages to make a difference in the students’ lives regarding how they view themselves and the others around them.After all, education is not about stuffing students with knowledge; it is mostly about inspiring and empowering young learnerswith the knowledge that...

Abstract Climate change/variability is a major driving factor among others that contribute to the spread of suitable malaria vectors’ geographical extent. The current study employed comparative spatial–temporal analysis using bioclimatic envelope modeling to predict and quantify the possible surge of suitable malaria vectors’ habitats in new hotspots in Kenya. BIOCLIM and BIOCLIM True/False models were run with model data from HADCM3, CCCMA and SCIRO IPCC future climatic projections under...

Background: The consumption of energy drinks (EDs) is increasing in the general population, but little is known about the consumption of EDs among pupils in Africa. This study was designed to assess the consumption of EDs among pupils between 10 and 17 years of age and to assess average caffeine concentrations contained in EDs sold in Lubumbashi. Methods: We conducted a cross-sectional survey in five schools using a standardised questionnaire taken face-to-face. Samples of locally purchased...

Global surveys have highlighted rise in consumption of cannabinoids among residents of both developed and developing countries. Cannabinoids cause severe damage to the cardiovascular, nervous, respiratory, and renal systems, and have been linked with several deaths. Despite these adverse health effects, the use of cannabinoids has rapidly increased. This work seeks to estimate the prevalence of cannabinoid abuse among Egyptian university students and explore the associated risk factors. A...
