Bibliography: leaves 145-150. / This research attempts firstly to estimate both the level and shape of the mortality curve of the Black South African population group circa 1985 by the application of indirect demographic techniques to the reported deaths for Blacks for the period 1984- 86 and an estimate of the Black population in mid-1985. The life tables thus produced are then combined with the official South African Life Tables for Whites, Coloureds and Asians to produce a weighted average national life tables circa 1985. These national life tables are then compared with those produced by applying the Bennett and Horiuchi method to national data for the 1984-86 period in order to decide on suitable adjustments to make when applying the Bennett and Horiuchi method to national data for the period 1989-91 and beyond.

Bibliography: leaves 142-149. / The nature of human decision making dictates that a decision must often be considered under conditions of uncertainty. Decisions may be influenced by uncertain future events, doubts regarding the precision of inputs, doubts as to what the decision maker considers important, and many other forms of uncertainty. The multicriteria decision models that are designed to facilitate and aid decision making must therefore consider these uncertainties if they are to be effective. In this thesis, we consider the treatment of uncertainty in multicriteria decision making (MCDM), with a specific view to investigating the types of uncertainty that are most relevant to MCDM, [and] how the uncertainties identified as relevant may be treated by various different MCDM methodologies.

This exploratory study investigated changes in the allocation of household expenditure between various product or service categories in a sample of South African low-income or 'bottom of the pyramid' (BoP) households. First, the mixed methods research quantified the monthly income and expenditure fluctuations in the sample of households over a period of four months. In addition, study identified and quantified expenditure category trade-offs in the target households. Finally, a qualitative inquiry explained the reasons for the fluctuations and the trade-offs identified in the first two components. The study was based on the existing BoP proposition and specifically focused on BoP consumer decision-making theory. Methodologically, the study was a monthly longitudinal panel over four months. The quantitative component employed a once-off baseline questionnaire to gather household data. The participating households then completed monthly self-complete financial diary questionnaires that recorded both income and expenditure. The qualitative component involved interviews with representatives from the participating households and provided details to explain the underlying causes for changes in monthly expenditure patterns. The study was conducted in four provinces with eighty BoP households participating in the research. The study found significant variation in both household income and expenditure between months. The variation and consequent trade-offs between expenditure categories was caused by calendar-related phenomena (such as the festive season), income shocks, unforeseen expenses and spreading the household budget over multiple months. In addition, large fluctuations in income resulted in a constantly shifting allocation of expenditure to categories that required the most attention at a particular point in time. Informal savings (stokvels) and micro-enterprise expenses also contributed to fluctuations in income and expenditure. This study provides unique insights that fill a vacuum in the current body of academic and industry knowledge for this segment of close to forty million BoP South Africans. No study of this nature has been published in either South African or international journals.

Includes abstract. / Includes bibliographical references (p. 149-222). / Conventional market orientation philosophy holds that behavioural and philosophical/cultural aspects of marketing are fundamental to an organisation. Prior research on strategic orientation in marketing research has focused on the construct of market orientation, which has been shown to have strong positive relations on business performance. In the present research, the effects of market orientation on performance are assessed concurrently with two other types of strategic orientation: technology orientation and learning orientation. In addition, we assess the mediating properties of entrepreneurship and innovativeness on the relationship of these three types of strategic orientation on business performance.

Brand engagement, or the process of how customers and other stakeholders form emotional or rational attachments to brands has garnered considerable attention in the marketing literature in recent years. Brand engagement is important because it is a construct strongly related to brand equity, or in simple terms the "value of the brand". Recently, the nature of brand engagement has also changed significantly because of the advent of social media. Not only do users of these social media share personal information with each other, they also comment on, contribute to, and share opinions on the brands that engage them. While the literature is extensive on brand engagement and social media, most of the emphasis is on customers, rather than other stakeholders such as employees, suppliers, and investors. Moreover, the research focuses almost entirely on consumers, the customers of business-to-consumer firms, rather than on the industrial and organizational customers of business-to-business (B2B) firms or their stakeholders. Only very recently have scholars begun to explore both customer and employee engagement and their effects on firm performance in both the business-to-consumer and business-to-business arenas. The research presented in this dissertation attempts to grow the literature in two ways. First, it focuses on brand engagement in business-to-business firms rather than business-to-consumer; second, it does this by studying a stakeholder group other than customers, namely, employees. Moreover, it does this through the employee lens, rather than the lens of the firm; in other words it explores how employees engage with firms rather than how firms engage with their employees. The study utilizes an exploratory research design focusing on qualitative data. The data consist of job reviews posted by employees of B2B firms on the social medium Glassdoor.com. Glassdoor.com collects company reviews and real salaries from employees of a range of organizations and displays them anonymously, and users are also able to rate their employees on a five-star scale. The firms chosen were based on a ranking study by the research firm Brandwatch, and were split into two groups, namely the 30 top ranked firms, and the 30 bottom ranked firms. These reviews were then analyzed, using Hart's theory of word choice and verbal tone, in DICTION, the content analysis software. The results indicate that there are significant differences between top ranked and bottom ranked firms, and also between top rated and bottom rated firms. Employees of top ranked firms are significantly more optimistic in their reviews, while employees of bottom ranked firms express significantly more certainty, activity and realism. There are no significant differences with regard to commonality. With regard to firm ratings, the employees of highly rated firms are significantly more optimistic, while employees of low rated firms score significantly more on all the other dimensions of word choice and verbal tone. The employees of top ranked firms are significantly less insistent in their reviews but display significantly more embellishment, variety and complexity. Similarly, in the case of firm ratings, highly rated reviews are significantly less insistent, but exhibit significantly more embellishment, variety and complexity. The thesis contributes to academic knowledge in four ways. First, it is the first study to consider brand engagement in the business-to-business environment from an employee perspective. Second, the study contributes by providing a perspective on brand engagement from two sides, namely highly ranked B2B companies and low ranked B2B companies, as well as highly rated B2B companies and low rated B2B companies. It highlights the differences between these two groups with regard to brand engagement. Furthermore, it permits a focus on the differences between employees who rate an employer brand high versus those that rate it low, regardless of how the brand is ranked independently. Stated differently, in a brand engagement context, the study identifies specific dimensions or calculated variables that distinguish high and low rankings and ratings. Third, this is the first study that examines employee brand engagement using Hart's theory of word choice and verbal tone. This means that it employs a robust means of comparing pieces of text, or in this particular case, the text resulting from an employee's review and rating of an employer, as a proxy for employee brand engagement. Fourth, this study is the first to use the DICTION content analysis software to examine employee brand engagement in a business-to-business context. It demonstrates DICTION's ability to operationalize Hart's five dimensions of text, and the calculated variables, as well as confirming DICTION's capacity to handle very large text files. The study also has implications for marketing managers, and for brand executives in the business-to-business arena specifically. First, it enables managers to identify the most important dimensions of brand engagement according to Hart's theory, when employee reviews are posted on social media. When managers are able to discern which dimensions figure prominently in the most highly regarded brands according to employees, they can begin to formulate strategies that might enable them to develop these dimensions in their own environment. Likewise, when they are able to distinguish the dimensions that mark the least highly regarded brands, or the dimensions that occasion negative reviews, they will be able to develop strategies that enable their firms to overcome these effects. Second, the use of data such as that available on Glassdoor will allows managers to compare the nature of their brand engagement to others, such as competitors or firms they wish to benchmark against, and to develop strategies that will enable them to shift their level of brand engagement over time. Third, the results of the study reinforce the notion that brands and human capital are more important and interlinked than most managers acknowledge. The management of these two assets therefore requires more than occasional attention; rather, they should become part of regular organizational brand strategy.

Convergence trade, by definition, is buying an asset now to be delivered at some date in the future and selling a similar asset, to be delivered at the same future date, at a higher price. In this paper, implementation of bond convergence trade is explored in the South African market. This is in spite of the features of the South African bond market. The South African bond market is significantly different from markets where bond convergence trade has previously been tested. Duration was subsequently introduced in identifying similarities between bonds, and this is the major difference introduced compared to prior work in the literature. The results showed that the trades give, on average, negative returns. However, further investigation into the impact of interest rates not only on the trade, but over the period of investigation and future expected interest rates, is required, before the results can be appropriately interpreted.

This study seeks to establish if companies use derivatives and if so what kinds of derivatives. It does not seek to establish the reasons for derivative usage as is commonly done in Wharton Survey Style study.

Objectives: This work investigates the role for the content of print news media in determining asset prices and capital flows in a small open economy (South Africa). Specifically, it examines how much of the daily variation in stock prices, bond prices, trading volume and capital flows can be explained by phrases in the print news media. Furthermore, this work links such evidence to the existing theoretical and empirical literature. Methods: This work employs natural language processing techniques for counting words and phrases within articles published in national newspapers. Variance decompositions of the resulting word and phrase counts summarise the information extracted from national newspapers in this way. Following previous studies of the United States, least squares regression relates stock returns to single positive or negative 'sentiment' factors. New in this study, support vector regression relates South African stock returns, bond returns and capital flows to the high-dimensional word and phrase counts from national newspapers. Results: I find that domestic asset prices and capital flows between residents and non-residents reflect the content of domestic print news media. In particular, I find that the contents of national newspapers can predict 9 percent of the variation in daily stock returns one day ahead and 7 percent of the variation in the daily excess return of long-term bonds over short-term bonds three days ahead. This predictability in stocks and bonds coincides with predictability of the content of domestic print news media for net equity and debt portfolio capital inflows, suggesting that the domestic print news media affects foreign residents' demand for domestic assets. Moreover, predictability of domestic print news media for near future stock returns is driven by emotive language, suggesting a role for 'sentiment', while such predictability for stock returns further ahead and the premium on long-term bonds is driven by non-emotive language, suggesting a role for other media factors in determining asset prices. These results do not seem to reflect a purely historical phenomenon, finite-sample biases, reverse causality, serial correlation, volatility or day-of-the-week effects. The results support models where foreign agents' short-run beliefs or preferences respond to the content of domestic print news media heterogeneously from those of domestic agents, while becoming more homogeneous in the medium term.
