Abstract A common molecular variant of the angiotensinogen gene had been reported to predispose some ethnic groups to hypertension. This case-control study was designed to determine the frequency and association of the angiotensinogen M235T al1ele with hypertension in residents of Calabar and Uyo cities, south-south Nigeria. The study involved 1308 subjects, 612 patients and 696 controls. The M235T variant was investigated using an allele specific polymerase chain reaction and enzymatic diges...
ABSTRACT This study assessed a learning environment where learners were exposed to authentic and rich language input, and it has shed light on the use of multimedia pedagogies in second language (SL) teaching. By using videos, the study explored the impact of multimedia on language comprehension. The study was conducted in Omusati Region, Namibia on Grade 11 learners doing English as a Second Language NSSC Ordinary Level at a selected secondary school. Two Grade 11 classes were selected to b...
Abstract In the 21st century, institutions of higher education are required to broaden their curricula to equip students with global competency skills. The 2014/2015 academic year marked a collaboration project between postgraduate students from the University of Namibia and the William Paterson University in New Jersey in the Educational Technology module using the Facebook web page to promote global competency skills among students. This study ought to understand the University of Namibia ...
ABSTRACT Crop water productivity models are important tools in evaluating the effect of different irrigation regime on crop yield. AquaCrop model is a crop water productivity model adopted by the Land and Water Division of FAO in the year 2009. It simulates yield responds to water for herbaceous crops, and it is particularly suitable in addressing conditions where water is a key limiting factor in crop production such as in northern Ghana. The objective of this study was, to calibrate the Aq...
ABSTRACT This study investigated the effects of Project-Based Learning (PBL) for Namibia Senior Secondary Certificate Ordinary (NSSCO) algebra in selected senior secondary schools in Kavango West region. The study employed a quantitative approach. Furthermore, a quasi-experimental non-equivalent (pre-test - post-test) control research design was used to collect data from one school for two weeks. A sample of 80 learners was randomly selected from the poorest performing school (school E) and ...
Abstract Background: Studies have shown that the traditional banking sector is under threat from digital banks and financial technology (fintech) organisations that can operate with a lower cost base and respond to the market faster. In response to this threat, leading banks have implemented Robotic Process Automation (RPA) to reduce costs and simplify operations. The adoption of RPA has, however, proven to be challenging as in many cases the impact of automation technology implementations is...
ABSTRACT Good recordkeeping systems are reported to have existed in the colonial period, while general crisis situations have been reported in many postcolonial African nations, including Zimbabwe. The main concern of this study was why this seemingly success factor in colonial recordkeeping failed to continue in postcolonial Africa, including Zimbabwe, as reported in various studies. In light of these insights, this study therefore sought to conduct an investigation of the status of records...
ABSTRACT Pito is a traditional alcoholic beverage that is mostly brewed in the three northern regions of Ghana. Although widely consumed and used during many festivities, poor shelf-life limits its economic potential as an income generating venture for most women. The study was carried out to improve the shelf life through the addition of Moringa oleifera leaf extract and pasteurization. The study was in two phases, that is, the extract level testing phase and the storage phase. The former ...
ABSTRACT The purpose of this research is to explore the influence of performance expectancy, effort expectancy, social influence, facilitating conditions and behavioural intention on consumers’ adoption of Internet banking in Ghana. Studies on Internet banking in developing countries have so far focused more on issues relating to adoption, use, deployment and diffusion. The most dominant among these areas is studies on adoption. However, there still remain salient factors of Internet bankin...
ABSTRACT The study purposed to investigate the experience, contribution and opinions of users of institutional repository (IR) developed at University of Ghana (UG) and also find the challenges facing the institutional repositories (called UGSpace) at the University of Ghana. This study is conducted using a qualitative research approach and the case study research technique. The data collection tool was an unstructured interview guide. The study found out that most of the respondents were una...
ABSTRACT The ubiquity of the internet affords both healthcare professionals and lay users the opportunity to access a wide range of Online Health Information (OHI) resources. However, in the midst of the abundance, the OHIseeker (OHIS), whether medically trained or not, remains the primary decision maker who determines the quality or otherwise of the information consumed. With quality of online information generally being called into question by many researchers who believe that the content i...
ABSTRACT This research is geared toward assessing the extent cost of retaining an aging server hardware has affected the transition to current server hardware in a developing country like Nigeria. Primary data were the major source of data for the study. The collected data were subjected to multiple regression analysis. The study found that software update, Random Access Memory (RAM) maintenance, hard disk maintenance and power/ cooling costs have significant cost impact on aging server har...
ABSTRACT This research was conducted to determine if quality assurance and its strategies are effective for successful project execution in the construction industries. Data was obtained from both primary and secondary sources. The primary sources consisted of questionnaires and observations while the secondary data consisted of texts, websites and journals. Percentages were used to analyze data and analysis of variance (ANOVA) was adopted in testing hypothesis. Among the major result of da...
ABSTRACT Orange-fleshed sweetpotato (OFSP) is an important root crop capable of ameliorating vitamin A deficiency that is a public health concern in Sub Saharan Africa. However, most of the OFSP cultivars have relatively short shelf life largely due to improper pre-and post- harvest management. This study investigated the effect of two curing (field-piled and in- ground) and two household-level storage (sand box and heap) methods on the shelf life of two OFSP cultivars (Apomuden and Nane) in...
