The Impact

Abstract Background Scientometrics is used to assess the impact of research in several health fields, including Anesthesia and Critical Care Medicine. The purpose of this study was to identify contributors to highly-cited African Anesthesia and Critical Care Medicine research. Methods The authors searched Web of Science from inception to May 4, 2020, for articles on and about Anesthesia and Critical Care Medicine in Africa with ≥2 citations. Quantitative (H-index) and qualitative (descriptive analysis of yearly publications and interpretation of document, co-authorship, author country, and keyword) bibliometric analyses were done. Results The search strategy returned 116 articles with a median of 5 (IQR: 3–12) citations on Web of Science. Articles were published in Anesthesia and Analgesia (18, 15.5%), World Journal of Surgery (13, 11.2%), and South African Medical Journal (8, 6.9%). Most (74, 63.8%) articles were published on or after 2013. Seven authors had more than 1 article in the top 116 articles: Epiu I (3, 2.6%), Elobu AE (2, 1.7%), Fenton PM (2, 1.7%), Kibwana S (2, 1.7%), Rukewe A (2, 1.7%), Sama HD (2, 1.7%), and Zoumenou E (2, 1.7%). The bibliometric coupling analysis of documents highlighted 10 clusters, with the most significant nodes being Biccard BM, 2018; Baker T, 2013; Llewellyn RL, 2009; Nigussie S, 2014; and Aziato L, 2015. Dubowitz G (5) and Ozgediz D (4) had the highest H-indices among the authors referenced by the most-cited African Anesthesia and Critical Care Medicine articles. The U.S.A., England, and Uganda had the strongest collaboration links among the articles, and most articles focused on perioperative care. Conclusion This study highlighted trends in top-cited African articles and African and non-African academic institutions’ contributions to these articles.

Purpose This study aims to describe South African consumers’ wine risk perception on varietal level with recommendations for Chenin blanc. Design/methodology/approach An exploratory mixed methods approach was followed where qualitative data were used to develop the questionnaire. Quantitative data were collected from 2,051 respondents using an online survey. ANOVA and Fischer least significance difference tests were used to indicate statistical significance. Findings Significant perceived risks (PRs) associated with Chenin blanc across age and ethnic groups were functional, time and financial risks. Risk-reducing strategies (RRS) in the white wine category were favourite brands and a trusted store, while Sauvignon blanc was also described as an RRS. Recommended Chenin blanc RRS include tastings and events with food. Research limitations/implications Measurement of PR remains challenging. This research approach can be reproduced and/or adapted to investigate other struggling varietals and/or regions-of-origin. The convenience sample limits generalisability. Practical implications Segments were identified to develop new markets for Chenin blanc. RRS emphasise the importance of real sensory experience rather than media exposure to build knowledge and familiarity. Originality/value This study is a pioneering endeavour in terms of using an exploratory mixed methods research approach to investigate and describe risk perception of a specific wine varietal. Recommendations, with implications for strategic marketing decisions, are made for South African Chenin blanc.

Password Security

Background: Online security is a growing concern and user authentication through passwords remains an important mechanism to protect online assets. Research to date has highlighted the need to address human behaviour but without an indication of where the emphasis of security education, training and awareness (SETA) initiatives should be, beyond improved password practices. Objectives: The aim of this study was to, through analysis of the password behaviour of South African online consumers: (1) understand the prevalence of poor password practices among consumers overall and (2) identify specific password deficiencies prevalent among different demographic groups to be focus areas for tailored intervention programmes. Method: The study uses a quantitative research approach. An online survey was used to gather demographic data, perceptions about online security and applied password practices. A sample of 737 valid responses was analysed for this research. Results: Based on the descriptive analysis of the responses three key observations were made. Firstly, there is a distinct difference in the incidence of poor password practices for all respondents and thus support for tailored interventions. Secondly, there are variances between the practices within different demographic groups that could be used for customisation of interventions. Finally, the different poor practices cannot be uniquely attributed to one particular set of demographics. Conclusion: The study concluded that to improve computer password security in South Africa, password SETA programmes should be customised for areas where individual needs exist and not merely per password practice or demographic group.

Sporting Performance

This study explores whether South African national sporting performance can influence investors in such a way that it has the ability to impact on market returns. Using standard event study methodology, this study determines the constant mean return using the daily All-Share price index on the JSE for the period of 1 January 1990 to 31 December 2010. This study focuses on three of South Africa’s most popular sports, namely soccer, cricket and rugby, and examines if these three sports have the ability to influence market returns. Although there is some evidence of a relationship between stock returns and sporting performance in the descriptive analysis, the regression results indicate that sporting performance in South Africa does not significantly explain abnormal market returns on the JSE. The study provides a number of possible reasons for this finding and concludes by suggesting areas for future research.

Wine Matrix

Traditionally, the sensory properties of wine were characterized using a trained panel and descriptive analysis (DA)—a static sensory evaluation method. As wine is a complex mixture, with evolving sensory properties, a way to capture these changes is needed in order to fully describe the sensory experience of wine perception. In this study, temporal check-all-that-apply (TCATA), a dynamic sensory evaluation method, was used to characterize model wine samples reminiscent of a white, hybrid wine. Twelve model wines varied in levels of ethanol, glycerol, and caffeic acid, representing commercial levels in Pennsylvania. Samples were evaluated for up to three minutes by a trained TCATA panel (n = 12) for flavor, taste, and mouthfeel attributes. In general, the experimental factors, ethanol and glycerol, along with interactions between factors, had the greatest temporal effects, with significant differences in flavor attributes occurring within the first 30 s of evaluation, while taste and mouthfeel attributes showed significant differences throughout the evaluation period. Overall, ethanol had the greatest impact on temporal wine perception. The findings of this study further suggest that a temporal evaluation method, like TCATA, should be paired with DA to completely characterize a complex and evolving sample. Further, changes in wine matrix components affect sensory perception both in direct and indirect ways—the latter indicated by taste-taste suppression and cross-modal interaction effects.

Imaginative Play

A preliminary investigation was carried out in which South African preschoolers' spontaneous play was related to their television viewing habits, a year after its full scale introduction of television in South Africa. It appears that the limited and relatively benign nature of the television service has no adverse effect reflected in play, such as increases in the overt expression of aggression and anxiety. If anything the television programmes currently broadcast in South Africa have the effect of stimulating imaginative play in white middle class preschoolers.
