Thesis (MTech (Biomedical Technology))--Cape Peninsula University of Technology, 2009. / In recent years antioxidants present in various beverages have attracted a great deal of research interest due to their potential benefits to human health. Epidemiological evidence shows an indirect relationship between the intake of beverages rich in antioxidants and the reduced incidences of some chronic diseases, certain cancers and coronary heart disease mortality. The study was divided into two phases. The aim of the first phase was to compile a database of antioxidant capacities (Oxygen radical absorbance capacity, Ferric reducing antioxidant potential and Trolox equivalent antioxidant capacity) and contents (polyphenols, flavonols, flavanols, anthocyanins and vitamin C) of selected South African beverages. The second phase of the project included an intervention study to investigate the short term in vivo effects of consumption of an antioxidant-rich beverage, rooibos, on the antioxidant and oxidative stress status of human participants. The parameters that were investigated in human plasma included the total antioxidant capacity (ORAC and FRAP) and content (total polyphenols) as well as the reduced-oxidised glutathione ratios (GSH/GSSG) in erythrocytes. Results from this study were used to compile a database for antioxidant capacities and contents of selected South African beverages. The results showed that, in the case of fruit juices their antioxidant capacity and content covered a wide range. This could be attributed to the juice's differences in fruit composition, e.g. either as a single fruit or as a combination of two or more fruits. In the case of wines, red wines had the highest antioxidant capacity for all the beverages tested and had 22 times higher polyphenols compared to that of white wines. Results also indicated that black tea and coffee had a higher antioxidant capacity and polyphenol content than the local herbal tea, rooibos. The duration of extraction (brewing) of the teas also influenced the antioxidant capacity. Correlations between the three antioxidant capacity assays were very high in the case of wines and teas, but lower in the case of fruit juices. This antioxidant database for South African beverages is useful not only to consumers, but also nutritionist, researchers, dieticians and functional food formulators.

M. Tech. Marketing / The primary objective of this study was to investigate the role that advertising plays in alcoholic beverage consumption patterns of the youth of Tshwane. Several secondary research objectives were set which include: examining the overall alcoholic beverage consumption of young people, the alcoholic beverage types and brands consumed, exposure to alcoholic beverage brand advertising, exposure to media in which alcoholic beverages are advertised, differences between males and females with regards to their consumption of alcoholic beverages as well as the alcoholic beverage types they consume, the relationship between age and alcoholic beverage consumption, income and alcoholic beverage consumption and other factors that can influence young people to consume alcoholic beverages.

Thesis (MBA)--University of Stellenbosch, 2005. / ENGLISH ABSTRACT: The global RTD market was one of the fastest growing drinks categories in the world in 2002 and many brewers and spirits companies have entered the new market. The RTD category gained most of their volume from the young adult consumers and across the boundaries of wine. spirits and beer. The strategic vision of the RID market determine whether this is a short intense fashion or a permanent feature in the drinks market, given the historical precedence of the mid to late 1980's when the wine cooler boom and later the alcopops (alcoholic carbonates) phenomenon passed as quickly as it came. The purpose of the research report sets out to investigate the global RTD markets in order to determine the strategic vision for the South African market. The study did a review of the top tcn RID markets and then focussed on the strategies and performance of the Australian and United Kingdom markets, due to the level of development and similarities in culture of these markets with the South African market. The analysis of the global RID markets showed the three successful RTD models are female, androgynous and male RIDs and consumers perceived and use the three types of RTDs differently. Amongst the most important suggestions the author recommends that the biggest opportunity for the South African R TD category is to gain market share from the beer market in the male sector, which is by far the biggest seller of alcoholic beverages in South Africa. The current successes in the South African market came from female and androgynous brands, but it is very difficult to maintain brand loyalty within these segments due to the nature of the young adult consumers and female drinkers. / AFRIKAANSE OPSOMMING: Die wereld gereed·om-te-drink (RTD) mark was een van die vinnigste groeiende drank kategoriee in die wereld in 2002 en baie brouerye en spiritualieë maatskappye het tot die nuwe mark toegetree. Die RTD kategorie het die meeste van sy volume verkry van die jong volwasse verbruikers en van verskillende kategoriee soos wyn, spiritualieë en bier. Die strategiese visie van die RTD mark bepaal of dit 'n gier of 'n permanente kenmerk in die drank mark is, soos voorafgegaan van die middel tot laat 19805 toe die wyn verfrissers en later die "alcopops" (alkoholiese karbonate) verskynsel so vinnig verdwyn het as wat dit gekom het. Die doel van die navorsingsverslag is om die wereld RTD mark te ondersoek om 'n strategiese visie vir die Suid-Afrikaanse mark te bepaal. Die navorsingstudie het die top tien RTD markte ondersoek en toe gefokus op die strategiee en doeltreffendheid van die Australiese en Verenigde Koninkrykte markte as gevolg van die vlak van ontwikkeling en ooreenkomste in kulture van die markte met die Suid-Afrikaanse mark. Die analise van die wereld RTD mark het getoon dat die drie suksesvolle vorme van RTDs is vroue, tweeslagtige en mans RTDs en dat verbruikers verstaan en gebruik die drie tipes van RTDs verskillend. Van die belangrikste voorstelle wat die skrywer maak is dat die grootste geleendheid vir die Suid-Afrikaanse RTDs is om mark aandeel van die bier kategorie in die mans sektor te verkry omdat dit die grootste alkohol kategorie in Suid-Afrika is. Die huidige sukses in die Suid-Afrikaanse mark het gekom van die vroue en tweeslagtige markte, maar dit is baie moeilik om die verbruikers lojaal te hou vir die RTD produkte in die segmente as gevolg van die aard van die jong volwasse verbruikers en vroue drinkers.

A research report submitted to Wits Business School, Faculty of Commerce, Law and Management, University of the Witwatersrand, Johannesburg, in partial fulfilment of the Degree of Master of Management in Strategic Marketing November 2015 / Building, maintaining and measuring consumption frequency over a specific period of time has become the primary driver of success for nonalcoholic beverage organisations; however, there is limited research on youth consumption frequency within South Africa. Using the Theory of Planned Behaviour, the study aimed to investigate the impact of brand association, flavour variety, peer influence and perceived value on consumption frequency intention in the sparkling soft drink (SSD) category amongst youth in South Africa. A quantitative research design was followed and data collected from 300 research participants aged between 16 and 24 years in Soweto, Gauteng Province in South Africa. The collected data was analyzed using SPSS 22 and AMOS 21 statistical packages for structural equation modelling. All four hypotheses are supported, with results indicating a positive relationship between brand association, flavour variety, peer influence, perceived value and consumption frequency intention. Peer influence and perceived value have a significantly stronger influence on consumption frequency intention. The results also indicate that flavour variety “ambiguous SSD flavour names” scored higher amongst 16 to 18 years olds. Ambiguous flavour naming strategies have proven to be successful in other beverage categories. Quantity-frequency (QF), a consumption frequency measurement instrument has been used, with consumption skewed towards “sharing” with friends or family. This study contributes significant new knowledge to the existing body of marketing literature in Africa and consumer behaviour in emerging markets. This study has implications for practitioners, academicians and public policy makers. / MT2017

Introduction: Studies reveal differential cognitive effects of alcohol use, with moderate to heavy alcohol having some beneficial effects in older adults, whereas in young adulthood, heavier alcohol use produces deficits. The aim of the research was to investigate the relationship between patterns of alcohol use and the cognitive and symptomatic functioning of university students over one year, and to discern which demographic, clinical and alcohol factors might moderate cognitive outcomes. Method: The sample included undergraduate Psychology students from a South African University, aged 18 to 23 years (n = 86). The sample was divided into two alcohol use groups based on four categories from the Alcohol Use Disorders Identification Test (AUDIT) (Babor et al., 2001), including a lighter drinking group (Safe/Hazardous, n = 74) and a heavier drinking group (Harmful/Dependent, n = 12). The two drinking groups were statistically equivalent for distribution of age, gender, English first language, race groups, history of neurological or psychiatric vulnerability, a measure of initial intelligence/cognitive reserve (Peabody Picture Vocabulary Test: PPVT-4) (Dunn & Dunn, 2007) and for a measure of test-taking validity (Immediate Postconcussion Assessment and Cognitive Test: ImPACT Impulse Control) (p = < 0.05 in all instances). Participants were tested on the computerized ImPACT battery (ImPACT, 2007) at three intervals over an academic year (May, August, October 2012). Repeated measures ANOVAs were used to investigate cognitive and symptomatic differences between the two alcohol use groups, in association with moderating factors. Results: The heavier drinking group revealed: (i) poorer performance on ImPACT Visual Motor Speed, Reaction Time and Cognitive Efficiency Index scores, including less ability to benefit from practice over time; (ii) symptom reports of severe Numbness/Tingling, Balance problems and Dizziness. Deleterious cognitive outcome was exacerbated by longer lifetime duration of alcohol use, passing out monthly, beer or wine drinking, smoking or substance use. Conclusion: Deleterious cognitive and symptomatic effects of heavy alcohol use are in evidence for undergraduate university students implicating current and/or cumulative alcohol induced brain impairment. The results of the study are of concern for optimal academic performance of students at an early stage of university level study, who engage in heavier (Harmful/Dependent) drinking patterns, with negative implications for future career attainment.

Thesis (MBA)--Stellenbosch University, 2011. / ENGLISH ABSTRACT: Objective: The purpose of the present study is to empirically examine the relationship between brand-level alcohol advertising and alcohol consumption in South Africa. The effect that price has on alcohol consumption is also investigated in the analysis. Method: Using secondary quantitative time series data that include observations of brand-level sales volume, segment volume, brand-level market share, brand-level retail selling price (RSP) and brand-level advertising expenditure (spanning a 32 month period), statistical techniques such as tests for stationarity and co-integration were conducted to assess the association between the various constructs. Results: It was found that between January 2007 and August 2009, a period that included an economic downturn, own-brand advertising had little or no effect on brand-level sales volume (or consumption), segment sales volume and brand level market share. Conversely, price had a significant effect on sales volume, explaining between 48% and 56% of the variation in sales volume at brand-level and between 21% and 31% of the variation in brand-level market share. Conclusion: The results suggest that brand-level advertising has no significant immediate effect on consumption levels in the South African liquor industry, while the price of alcoholic beverages does have a significant immediate effect.

Thesis (M.Ed.) (Clinical Psychology) --University of Limpopo, 2008. / There is a considerable literature linking aspects of personality, parenting, and risk behaviors such as alcohol abuse. Three hundred African university students participated in a study of the relationship between personality, assessed with the NEO PI-R (Costa & McCrae, 1992), and alcohol use. Personality traits did not predict alcohol use among the students. It was also predicted that the Parental Bonding Instrument (PBI; Parker, Tupling, & Brown, 1979) would mediate the relationship between personality and alcohol use. Results of the current study revealed no significant relationship between parenting and alcohol use. The results are discussed with regards the use of the NEO PI-R’s validity in the population used.
