The main aim of this study was to determine the quality of vegetable oils consumed by the population in Yaoundé.

The study was carried out on 14 vegetable oils sampled following a survey. The antioxidant potentials of these oils were analyzed using the 2,2-diphenyl-1-picrylhydrazyl, FRAP total antioxidant capacity. The concentrations of some heavy metals (Pb, Cu, and Fe) were determined using flame atomic absorption spectrometry after acid digestion. The acid and peroxide values were assessed using methods described by the Cameroonian standard on vegetable oils.

The sample included 8 brands of which, 5 of refined palm oil, 4 of soybean oil, 1 brand of cottonseed oil, sunflower oil, and cold extracted olive oil, red palm oil bleached palm oil each. The antioxidant activity showed a good correlation, with red palm oil having the greatest antioxidant potential and bleached palm oil having the least antioxidant potential. The Pb, Cu, and Fe contents had the following conformities: 71.4%, 100% respectively. For the acid and peroxide values, we found 50% and 21.4%, respectively. Six of the fourteen (42.9%) analyzed oils contained less than 33 IU/g vitamin A.

These results highlight the poor quality of the oils consumed in Yaoundé.

The 21st-century has witnessed the catalytic effect of Information Technology (IT) on organisational operations through increased robustness and sustained competitive advantage in the knowledge economy. Technology’s disruptive diffusion has not sparred the human resource practice; thus, this study investigates the adoption of electronic Human Resources Management (e-HRM) by a telecommunications-based organisation in Zimbabwe. The study utilised a quantitative case design using a questionnaire targeting 130 managers and supervisors. In meeting the study’s objective, factor analysis using principal component analysis and varimax rotation was conducted. The results show that the three constructs had a direct impact on the adoption of e-HRM. The respondents agreed that e-HRM had automated employee records management and improved communication between employees and managers, increasing productivity. Identified benefits from the results include lowering administrative costs, delivering state of the art HRM services, enabling HR staff more time to focus on strategic reorientation, increasing HRM effectiveness and efficiency, and facilitating the scouting of the best talent globally. The respondents noted that aligning e-HRM processes to the HRM function had some restraints, such as unwillingness to accommodate change, confidentiality and security of personal records through hacking. The study generates new knowledge for benchmarking as Zimbabwean organisations endeavour to embrace e-HRM. The study contributes literature on e-HRM adoption, which appears scant in developing countries such as Zimbabwe. More research on e-HRM adoption in developing countries provides practical and theoretical implications for the HRM practice and the research community. Future studies could involve several organisations for more generalisability of the results.

The swift growth of technological improvements has supported the continuing transformation of the service sector, in its conversion from conventional physical service encounters handled by service professionals into customer-controlled self-service technologies (SSTs). Even though prior research attempts have been made in assessing the acceptance of technology in general, the insufficient focus is placed on self-service technologies. Further, understanding the target customer is crucial with the fierce competition existing in the market sided with the development of technology. Therefore, the purpose of this study is to investigate which elements comprise the customers’ technology playfulness and anxiety  and how it influence the use of self-service technologies in the Sri Lankan commercial banking sector. The study undertook a qualitative approach with 50 semi-structured interviews from Western province banking customers who use SSTs utilizing a non-probabilistic purposeful sampling strategy. The data were analyzed using the technique of thematic analysis. The findings revealed “Enjoyment”, “Fun”, “Innovativeness”, “Entertaining”, “Creativity”, “Pleasure” and “Appealing features” as the seven themes of technology playfulness motivating the use of SSTs and “Transaction doubts”, “Elderly difficulties”, “Verification doubts” and “Security doubts” as the four themes of hindering factors towards the use of SSTs in the banking sector. The findings would contribute to the literature gap on the customer movement towards self-service technologies. Insights from the study would support the practitioners in understanding how to improve with the proper use of technology and delivery of self-service technologies in the commercial banking sector of Sri Lanka.

Leaves of Ocimum basilicum, Leptadania hastata and Momordica balsamina are locally used by traditional birth attendants at pre and post-partum. The present study investigates the phytochemical and antimicrobial activity of the leaf extracts against isolates of L. monocytogenes. Standard microbiological techniques were used to isolate and identify the bacteria. Phytochemical analysis revealed the presence of tannins, flavonoids, carbohydrates, alkaloids, terpinoids and glycosides in the studied extracts. MIC of the extract of M. balsamina shows a total inhibition of Listeria monocytogenes at a concentration of 2,000µg/mL. No isolate was inhibited at concentration lower than 125µg/mL of M. balsamina extract. MIC of the extract against L. hastata was observed at a concentration of 2,000µg/mL. O. basilicum extract inhibited the growth of the isolates at a concentration of 2,000µg/mL. The MBC of the extracts, was between 5,000-0.61µg/mL were used, however, no antibacterial activity was observed on the bacterium with any of the three plants extracts at all concentration levels (0.61-5000πg/mL). The leaf extracts demonstrated significant inhibitory activity but lack bacteriocidal effects on L. monocytogenes. It was recommended that further studies on the preparation, effective doses and side effects of these extracts in animal models are warranted.
