- Description: Invasive alien plants (IAPs) of various kinds pose a threat to ecosystems, biodiversity, conservation and overall economy. In a world experiencing exponential increase in IAPs – this issue has become endemic, especially for developing countries such as South Africa. South Africa is a water scarce country and IAPs increase water stress. Thus, South Africa must invest in a more realistic, environmentally and economically inclusive policy outlook on the management of IAPs including aquatic weeds. This is especially urgent when considering the changing global climate, which is predicted to further reduce the quantity and quality of potable water. The Working for Water Programme (WfW) in South Africa aimed at addressing the issue of IAPs in a way that protects the environment as well as produces maximum return to society through poverty alleviation. As such, the aquatic weeds management strategy put in place for four of South Africa’s aquatic weeds Pista stratiotes, Salvinia molesta, Azolla filiculoides and Myriophyllum aquaticum - should be one that is cost-effective, efficient and sustainable; yielding the best possible return on investment. Since these four weeds are already under complete biological control, in the absence of biological agents, the WfW programme would have used herbicides to control these weeds. As such, this thesis conducted a retrospective analysis of the relative herbicide cost-saving associated with the use of biological control. To do this, due to existing limitations, E. crassipes was used as a surrogate weed and its herbicide control costs were used as proxy for the herbicide control cost estimates of the four selected weeds; with reasonable conversion factors applied to cater for the biological difference of the five weeds. Using the cost benefit analysis (CBA) framework, the net present cost (NPC) of each control method was calculated to which the relative cost-saving was considered to represent the avoided cost of using biological control instead of chemical control on these weeds. The avoided cost was used as the main benefit component when deriving the relative benefit cost ratios (BCR). Two scenarios were used, one assuming no follow-up requirement and the other assuming one follow-up requirement for chemical control. Using an 8% discount rate, the study found that the estimated cost of the biological control method on all four aquatic weeds was about R7,843,205 while for chemical control the estimated costs would have costed R149,580,142, R268,264,838 and R881,711,738 for application by means of a boat, bakkie and knapsack. Chemical control cost estimates would have increased to about R164,538,052, R295,216,120 and R1,008,761,000 for boat, bakkie and knapsack approach respectively when including a possible follow-up programme. These would have led to positive BCRs of 90.24:1, 164.97:1 and 557.99:1 across the three chemical control approaches without a follow-up (with BCR of about 99.67:1, 182.00:1 and 631.56:1 for the boat, bakkie and knapsack approach respectively with the accepted follow-up programme). When running a sensitivity test with varying discount rates of 5% and 10%, these results remained robust. As such, failing to reject the dominant hypothesis in literature, the main conclusion of the study is that biological control is indeed the more cost-effective management option compared to chemical control with respect to herbicide cost-saving. Further, biological control is most-likely to produce more environmental cost-saving and water-saving over chemical control. The study recommends the continued use of the biological control investment on the four aquatic weeds under study as well as on emerging aquatic weeds such as Iris pseudacorus, Nymphaea mexicana and Sagittaria platyphylla in South Africa.

- Description: With the prevalence of digitalisation in the medical industry, e-health systems have largely replaced the traditional paper-based recording methods. At the centre of these e-health systems are Electronic Health Records (EHRs) and Electronic Medical Records (EMRs), whose benefits significantly improve physician workflows. However, provision for user interface designs (UIDs) of these systems have been so poor that they have severely hindered physician usability, disrupted their workflows and risked patient safety. UID and usability guidelines have been provided, but have been very high level and general, mostly suitable for EHRs (which are used in general practices and hospitals). These guidelines have thus been ineffective in applicability for EMRs, which are typically used in niche medical environments. Within the niche field of Optometry, physicians experience disrupted workflows as a result of poor EMR UID and usability, of which EMR guidelines to improve these challenges are scarce. Hence, the need for this research arose, aiming to create UID guidelines for EMRs in Optometry, which will help improve the usability of the optometrists’ EMR. The main research question was successfully answered to produce the set of UID Guidelines for EMRs in Optometry, which includes guidelines built upon from literature and made contextually relevant, as well as some new additions, which are more patient focused. Design Science Research (DSR) was chosen as a suitable approach, and the phased Design Science Research Process Model (DSRPM) was used to guide this research. A literature review was conducted, including EHR and EMR, usability, UIDs, Optometry, related fields, and studies previously conducted to provide guidelines, frameworks and models. The review also included studying usability problems reported on the systems and the methods to overcome them. Task Analysis (TA) was used to observe and understand the optometrists’ workflows and their interactions with their EMRs during patient appointments, also identifying EMR problem areas. To address these problems, Focus Groups (FGs) were used to brainstorm solutions in the form of EMR UID features that optometrists’ required to improve their usability. From the literature review, TAs and FGs, proposed guidelines were created. The created guidelines informed the UID of an EMR prototype, which was successfully demonstrated to optometrists during Usability Testing sessions for the evaluation. Surveys were also used for the evaluation. The results proved the guidelines were successful, and were usable, effective, efficient and of good quality. A revised, final set of guidelines was then presented. Future researchers and designers may benefit from the contributions made from this research, which are both theoretical and practical.

- Description: This research falls under the general themes of macro-locational determinants and motives of Foreign Direct Investment (FDI) and the challenges faced by FDIs. Specifically, the research focuses on macro-locational determinants of FDI and the motives of Chinese FDI in Cameroon, and the challenges faced by Chinese FDI in Cameroon. This research is motivated by China’s interest in African countries as well as the reciprocal interest in Chinese FDI by African countries, especially Cameroon. While various FDI theories and previous empirical studies indicate that macro-locational determinants of FDI constitute a country’s principal comparative advantage to attract FDI, there is still no universally acceptable set of macro-locational determinants of FDI. Furthermore, some empirical studies assert that Chinese FDI does not follow conventional FDI theories or western approaches to FDI, especially when investing in African countries. It is suggested that some widely accepted macro-locational determinants of FDI are frequently ignored by Chinese FDI. While FDI theories identify four motives for FDI (resource-, market-, efficiency-, and strategic asset-seeking) as the main motives for investing in a foreign country, the motives for Chinese FDI, especially in Africa, have been questioned by some scholars, the media and politicians, due to the significant but seemingly counterintuitive investments made by Chinese state-owned FDI in politically unstable resource-rich African countries. Furthermore, differences in the motives of Chinese privately owned and state-owned firms identified in previous empirical studies have raised concerns, particularly regarding the motives of state-owned Chinese firms in Africa which suggest a stance of neo-colonialism by Chinese state-owned FDI. The research aims to identify the significant macro-locational determinants of Chinese FDI in Cameroon, to provide clarity on the motives of Chinese FDI and to identify the challenges faced by Chinese FDI in Cameroon. To achieve the aim of this research, hypothetical relationships based on FDI theory and previous empirical research were formulated between Chinese FDI and the proposed macro-locational determinants of FDI and the four identified motives of FDI. In this research, a positivist research paradigm using quantitative methods was followed. Accordingly, the research design and methodology was underpinned by the positivist paradigm. A descriptive and analytical survey methodology was utilised, using both primary and secondary data sources. Secondary data was collected from reliable and credible databases for the period 2004 to 2018 to generate a time series to test the hypothetical relationships pertaining to the macro-locational determinants of Chinese FDI in Cameroon. To test the hypothetical relationships pertaining to the motives of Chinese FDI and to identify the challenges of Chinese FDI in Cameroon, primary data was collected by means of a questionnaire using convenience and snowball sampling techniques. The validity of the findings on the macro-locational determinants of FDI was confirmed through unit root and cointegration tests. Confirmatory Factor Analysis (CFA) and Cronbach’s alpha coefficients were used to ensure the validity and reliability of the findings on the motives of FDI. To assess the hypothetical relationships on the motives for Chinese FDI, the hypothetical relationship on the macro-locational determinants of FDI was determined using Ordinary Least Square (OLS) regression, t-tests, one-way ANOVA, descriptive statistics and logistic regression. In addition, descriptive statistics were used to analyse the data on the challenges of Chinese FDI. The findings indicated that the main macro-locational determinants of Chinese FDI in Cameroon included market size, political risk, limited trade openness, real effective exchange rate, interest rate and human capital. The findings also indicated that market-seeking constitutes the main motive of privately owned Chinese FDI in Cameroon. The findings also indicated that the top four challenges faced by Chinese FDI in Cameroon include corruption, the ambiguity of the legal system of Cameroon, the difficulty to negotiate with government and privatisation officials and high levels of taxes. The findings of this research serve as a test of theory, given that they determine whether the macro-locational determinants identified from FDI theories are also significant macro-locational determinants of Chinese FDI. Furthermore, the findings have the potential to assist in policy formulation aimed at encouraging Chinese FDI into Cameroon. The findings could also assist the Cameroonian government to allocate national resources efficiently by prioritising identified macro-locational determinants. The findings provide clarity on the motives of Chinese FDI in Cameroon and could assist the government to negotiate better deals that may enable Cameroon to benefit optimally from Chinese FDI.

- Description: South Africa’s financial markets have become larger and more complex over recent decades. The number of market participants who are using technical analysis techniques to predict the market’s movement has been growing rapidly. This research aims to investigate if historical share prices can be used when forecasting the market’s direction and to examine the profitability of the Japanese candlestick patterns. The study is based on ten companies selected from the JSE top 40 2019 composition. These are Aspen Pharmacy Holding, Capitec Bank Holding LTD, Discovery LTD, Kumba Iron Ore LTD, Mondi PLC, Mr. Price Group LTD, MTN Group LTD, Naspers LTD, SASOL LTD, and Shoprite Holdings LTD. These were selected from the JSE top 40 based on market capitalization and sector. This research analyzes eight candlestick reversal patterns; four are bullish patterns namely: doji star, hammer, bullish engulfing and the piercing lines and the other four are bearish patterns namely: shooting star, hanging man, bearish engulfing and the dark cloud cover. The ARCH and GARCH models are used to test for correlation between past share prices and future share prices and the binomial test and the mean return calculations were used to test the profitability of candlestick patterns. The sample is from Thomson DataStream 2019 and IRESS SA 2019 and covers ten years with 2496 observations starting from 02 January 2009 to 31 December 2018. The findings from the ARCH and GARCH tests revealed that there is a serial correlation between the returns from the previous day and the returns for the current day. The results from the mean returns and the binomial tests show strong evidence that the shooting star, hanging man, bearish engulfing and the bulling engulfing are statistically significant in predicting the share price movements. On the other hand, there was no evidence that the dark cloud cover, piercing lines, and the bullish doji can predict share price movements. Additionally, further studies on this topic could be improved by adding different candlestick patterns and the total number of companies analyzed. The results could also be improved by analyzing the candlestick reversal patterns when they are used with other trading rules such as support resistance levels and oscillators.

- Description: This exploratory, comparative study aimed to investigate perceptions of the participants in the study in South Africa regarding the tax on sugar-sweetened beverages. The study further aimed to compare these perceptions with perceptions identified in selected foreign jurisdictions that have levied the tax on sugar-sweetened beverages. A voluntary, paper-based, anonymous survey questionnaire that included both closed- and open-ended questions was selected as the primary method of data collection. This questionnaire was administered to post-graduate Bachelor of Commerce Accounting and Postgraduate Diploma in Accounting students, aged twenty-one years and older, studying at three residential universities in South Africa, during the 2018 academic year. An extensive analysis of literature available on sugar-sweetened beverage taxes, both locally and internationally, was conducted. The two main constructs (construct 1: perception of the sugar-sweetened beverage tax and the price of sugar-sweetened beverages and construct 2: the social impact of the sugarsweetened beverage tax) were then analysed using descriptive statistics. This study found that there is a significant association between gender and perception that the sugary beverage levy will be beneficial to health, with female perceptions of the benefit of the sugary beverage levy being greater than that of males. Respondents appear to have a positive perception of the sugary beverages levy, understand the sugary beverage levy, as well as the health benefits that will be derived from the levy. Respondents supported the tax on sugar-sweetened beverages if the revenue generated was used to improve the health care system and if the price of healthy foods decreased. Female respondents were found to drink fewer sugarsweetened beverages than male respondents, but females reported higher sugar-sweetened beverage consumption during stressful periods. The current study can possibly provide policy makers with more information regarding acceptance of the sugar-sweetened beverage tax and shape guidelines for future amendments of the tax imposed.

- Description: The onset of globalisation and simultaneous changes in financial technology and financial reforms dissipated hurdles once faced in financial transactions among stock markets. Hence, stock markets around the world became increasingly integrated because there was a free flow of cross border investments. Consequently, international diversification diminished thereby undermining the ability of investors to diversify investments across borders. For that reason, recent literature on portfolio diversification is urging investors to shift their focus to domestic portfolio diversification as an alternative. On that account, this study aims to examine the co-integration and dynamic causalities between South African equity market sectors in order to ascertain the sectoral diversification opportunities available to domestic investors over time. The study was examined over the different phases of the business cycle as well as the full sample, i.e. 2004 – 2018, with a view to shedding light on the inter-sectoral diversification opportunities of domestic investors over the South African business cycle. The phases of the business cycle applied are a| expansion and boom; b| recession and recovery phase and c| stagnation phase. The Johansen co-integration and Granger-causality tests were employed. The hypothesis of the study is that, if sectors are not cointegrated, then diversification benefits can be reaped by constructing a portfolio that combines stocks from the respective sectors. On the whole, the findings of this study show that there are both long-run and short-run diversification opportunities across the different phases of the South African business cycle as well as the full sample. However, there are lesser diversification opportunities in the recession and recovery phase over both the long-run and short-run. These results indicate that domestic sectoral portfolio diversification is least effective when it is needed the most (i.e. in a period of heightened volatility such as recession and recovery phase). This study will contribute to the existing literature in two ways; firstly, to investors who intend to diversify their portfolios domestically rather than internationally and, secondly, after reasonably thorough research it was evident that there is scant literature on domestic sectoral diversification in South Africa. As a result, the study attempts to address this gap. Additionally, the essence of the business cycle in this study is to make investors aware of potential diversification opportunities when positioning their portfolios for the next shift in the business cycle.

- Description: The purpose of this research is to determine the extent to which a statutory merger in terms of the Companies Act, 2008, may be accommodated by the provisions of an amalgamation transaction in terms of section 44 of the Income Tax Act, 1962. The research method adopted is a legal interpretative research approach. South African company law underwent significant reform with the introduction of the Companies Act, 2008. One of the fundamental areas for reform was the need for a mechanism to appropriately accommodate a corporate merger, and thus, what is referred to as a statutory merger was introduced into South African company law. What is notable is that the statutory merger has been crafted to apply across a variety of circumstances that may arise in commerce, thus offering wide versatility. On the other hand, the tax relief afforded in terms of the corporate roll-over provisions in the Income Tax Act is designed to facilitate corporate transactions on a tax neutral basis, whilst balancing the concessions these measures introduce and the potential for tax avoidance. Consequently, the tax relief applicable to an amalgamation transaction will only apply within strictly prescribed parameters. The research shows an ongoing effort by National Treasury to amend the provisions of the amalgamation transaction to better accommodate a statutory merger, but highlights that there are nevertheless certain conflicting purposes (policy) for each piece of legislation. For these reasons, the focus and parameters of a statutory merger and amalgamation transaction do not align perfectly. The key areas of inconsistency identified in this research are threefold, namely (i) the creation of a new company as a consequence of a statutory merger is not accommodated in an amalgamation transaction; (ii) the process of compensating the shareholders of the amalgamated company in an amalgamation transaction is not clearly contemplated in the statutory merger provisions; and (iii) mergers between a company and its shareholder currently present numerous complexities from both a company law and taxation perspective. The research concludes that the flexibility afforded under the statutory merger is largely minimised for parties who wish to simultaneously enjoy the tax relief afforded under an amalgamation transaction.

- Description: This thesis examines and analyses the current nature of intra-regional trade between member states of the proposed Tripartite Free Trade Area in order to contribute to an understanding of the potential for intra-regional trade within the region to increase. Trade Complementarity Indexes were used to determine how well the structures of the three founding blocs’ major imports and exports match. The results show that there is a high degree of trade complementarity in the trade of the top 5 major products traded between the regional groups. With the proposed TFTA in place, high trade complementarity could lead to increased trade between the regional groups. Trade Intensity Indexes were used to determine how intensively the three founding blocs trade with one another. Results from the indexes help determine the extent to which the blocs currently view each other as important trading partners and the implications of this for the proposed TFTA. Results show that EAC and SADC as well as EAC and COMESA viewed each other as significant trading partners while SADC and COMESA did not for the majority of the years from 2001 to 2018. With the TFTA in place, intra-regional trade could be strengthened among the members who currently trade intensively because tariffs between them would be progressively eliminated as required by the TFTA Agreement. Revealed Comparative Advantage Indexes were used to gain insights on whether member states have any comparative advantage in their top 5 exports. Results from the indexes were used to determine whether member states have comparative advantage in similar or dissimilar major exports and the implications of this for the proposed TFTA. Results show that member states have revealed comparative advantage in similar products and these products present opportunities for joint-production among member states as well as sectors for product development once the proposed TFTA is in place. Revealed Trade Barrier Indexes were used to gain insights into the extent of ease of market access into each regional bloc’s market. Results from the indexes indicate whether major products imported from each other receive possibly discriminatory or preferential treatment. The results indicate that the majority of the top 5 imports sourced from each region receive preferential treatment. This indicates that there is ease of market access for the top 5 imports sourced from each other and this could promote increased intra-regional trade among member states in these product categories because tariff and non-tariff barriers to trade will be progressively eliminated once the TFTA is in place.

- Description: Over the years, the financial sphere and its systematic process has transcended from one paradigm to another. Most prominent is the traditional finance paradigm dominating the financial sphere majorly throughout the 1960s and 1970s. The ideology and the foundation of the traditional finance paradigm was centred on the concept of rationality. Within the context of the current research, the traditional finance paradigm postulates that individuals in the process of making investment decisions, acquire and analyse all available information in the stock markets, upon which they make a rational investment decision. In other words, the traditional finance paradigm portrays individuals as perfectly informed, rational decision makers, capable of objectively solving complex problems –Homo economicus. However, research in the field of psychology gave rise to the questions and concerns that started to emerge in the 1980s concerning the realistic nature of the assumptions of the traditional finance paradigm. As opposed to the assumptions of traditional finance, these research show that it is impossible for investors to analyse the shares of all the listed companies in the market in order to make rational investment decisions due to the ambiguous nature of information available. In the behavioural finance paradigm individuals’ decision making are viewed to incorporate factors such as emotions, heuristics, experiences, intuition and perceptions. These factors in turn are seen to induce biases (such as availability bias and overconfidence) which leads to subjective decision making. The concept of behavioural finance is based on realistic outcomes of events in the financial sphere for example, the repeated occurrence of financial crises in an environment where all participants are assumed to be rational. The behavioural finance paradigm challenges the assumption of the traditional finance paradigm which is embedded on the concept of rationality. The purpose of the present research is to investigate whether brands of listed companies on the Nigerian Stock Exchange trigger behavioural finance biases in investment decisions of individual investors in Nigeria. More specifically, the aim of the present research was to establish relationships between the independent sub-variables of brand knowledge (brand awareness and brand image) and brand relationship (brand loyalty and brand attachment), the mediating sub-variables of behavioural finance biases (availability bias and overconfidence) and the dependent variable (investment decisions). To this end, objectives and hypotheses were formulated to guide the research. In order to achieve the stated objectives and test the formulated hypotheses, the present research adopted the positivistic paradigm and the methodological process involved quantitative methods. Data was acquired by means of an online questionnaire from members of the Independent shareholders association of Nigeria and individual investors whose contacts were provided by an independent broker (n= 182). The research instrument showed satisfactory levels of validity on all measures (between 0.40 and 0.89) and a relatively highly internal consistency for reliability with Cronbach’s alpha coefficient scores of between 0.81 and 0.93. Descriptive and inferential statistical analyses were performed. Descriptive statistics involved frequency distribution, mean and standard deviation. Inferential statistics involved Spearman’s rank correlation coefficient, Multiple linear regression analyses, T-test and ANOVA. Using Spearman’s rank correlation coefficient, results show that all variables were positively correlated. Results of the Multiple linear regression analyses performed, indicated that there are positive relationships between brand awareness and investment decisions; brand awareness and availability bias; brand loyalty and investment decisions; brand loyalty and overconfidence; overconfidence and investment decisions. Furthermore, Multiple linear regression analyses also indicated that availability bias mediates the relationship between brand awareness and investment decisions; and overconfidence mediates the relationship between brand loyalty and investment decisions. Results of the T-test indicated that there is no significant mean difference found in the responses of the different sex group (male and female) on independent, mediating and dependent variables. While ANOVA indicated that there is a significant difference found between the age category of respondents and brand loyalty; age category of respondents and investment decisions. Based on the results of the analyses performed, conclusions, contributions and recommendations were enumerated. Practical recommendations were made to the government, individual investors, companies and brand experts, professional brokers, financial analysts and economy developers.

- Description: Namibia is a member country of the Common Monetary Area (CMA) with Lesotho, Swaziland and South Africa. South Africa is the anchor country to which the smaller member states have surrendered monetary policy authority. This thesis therefore examines the empirical relationship between the South Africa repo rate (SArepo) on the one hand and Namibia’s repo rate (Namrepo), Prime Lending Rate (PLR), Private Sector Credit Extension (PSCE), Consumer Price Index (CPI) and Gross Domestic Product (GDP) on the other hand. The credit channel of the monetary policy transmission mechanism informs the theoretical foundation of the thesis. Vector Autoregression modelling, variance decomposition and impulse response functions were used to explore the nature and strength of the relationship between the SArepo and said variables in Namibia. This thesis used quarterly data for the period 2003 to 2017. The variation in the Namrepo was predominantly explained by the SArepo, which confirmed that the Namrepo strongly followed the SArepo. The impulse response function results found that the impact of a contractionary monetary policy shock (an increase in the SArepo) lasted for up to six quarters before the effect started to fade. The Namrepo exhibited a positive response to an increase in the SArepo, although the magnitude of the response started to fade after the third quarter. The PLR, as a representative of market rates in Namibia, also exhibited a positive response to an increase in the SArepo. The results were similar for the Namrepo and the PLR because changes to the NamRepo are passed through immediately to the market interest rates. On the real variables, the study found that a contractionary monetary policy shock initiated in South Africa resulted in an increase in inflation in Namibia of less than 0.4 percent, whereas output declined by less than 1.0 percent. Interestingly, a Namibia (domestic) contractionary monetary policy shock resulted in a decline in prices of less than 0.4 percent. GDP, on the other hand, exhibited a positive response to a contractionary monetary shock, with an increase of less than 2.0 percent in the first four quarters of the period observed. The results reflected that a contractionary monetary policy shock from South Africa was more effective with regard to its impact on GDP; however, a domestic monetary policy shock was more effective at impacting on domestic inflation compared to the impact from South Africa.

- Description: Globally, resource economic valuation has traditionally focused on monetary and market-based methods. However, there has been a recent move towards more transdiciplinary methods that encourage civil participation in resource economic valuation studies with the aim of generating more site-specific and appropriate values which can potentially improve natural resource management decisions. With a focus on Carolina, this thesis investigated whether citizen based participatory approaches can result in more appropriate resource economic values that reflect the social environmental values in Carolina. A qualitative research approach was adopted for this research which incorporated questionnaires and semi-structured interviews. The research also adopted an inductive thematic analysis. The findings of the research showed that local scale stakeholders have different perceived values of natural resources. The research further showed that national scale resource governance institutions deal with issues of natural resource economic conflicts related to environmental policy and decision making. The study will contribute to deepening an understanding of the contribution that a natural resource economics assessment, or analysis can have on equitable, sustainable and efficient water resource management in the face of water-use contestation

- Description: The use of the yield curve in forecasting economic recessions is well established in the literature. A new avenue of use for the yield curve has emerged in the form of using it to forecast bull and bear stock markets. This has the potential to change how investors manage portfolios. A dynamic market-timing strategy would allow investors to shift out of or in to stock markets based on the probability of bear stock market in the future. The relationship between the yield curve and the stock market is tested using an adapted probit model. This has proven positive with encouraging results for the US, India and Spain. This is tested for South Africa using the adapted probit model and the SA yield spread. Bear stock markets are identified on the JSE and forms part of the probit modelling process. Bear markets are identified using a six- and four-month criteria. As South Africa is a small, open and developing economy, the probit is also modelled using the US yield spread. The three probit models do not appear to track bear markets well. This is substantiated through the Henriksson-Merton parametric model test which tests for market timing ability. The results for the SA yield spread using both bear market criteria do not show market timing ability, however, the SA and US yield spread model does show potential market timing ability.

- Description: The main objective of this study was to question and investigate the primacy of illicit financial flows (IFFs) in developing countries, specifically focused on two countries namely China and South Africa. Africa is estimated to have lost approximately $1 trillion to IFFs over the last 50 years, which exceeds the financial assistance that these nations needed over the same period. For years. Africa has been the feeding ground for exploitation and resource plunder, and the narrative has always been Africa is underdeveloped because of this crime. Although this statement holds true in most African countries, what this paper seeks to do is to question whether capital flight, IFFs and more specifically tax evasion and tax haven activity are the reason for the deterioration of African economies or are IFFs perpetuated by economies with unsustainable growth paths. IFFs are an important factor when it comes to obstacles of economic growth. But are they the cause or effect? A very strong case can be made that they are the latter however, it is beyond the scope of this article to resolve this question. Its purpose is merely to assert that the question is a valid one and that presuming the answer could divert attention from the real question of economic development. This study contextualized the way in which IFFs are currently viewed in the world economic system according to the two approaches to development finance, and discussed modern monetary theory as an extension off these theories. Due to the nature of the study, the methodology employed is a case study approach between China and South Africa by means of extensive numerical and document analysis. Upon conducting this analysis on the primacy of illicit financial flows in developing countries there was difficulty in measuring IFFs. The reason for this is because IFFs have a range of estimates so it was very difficult to produce precise and accurate results. The key findings of this paper were that there seems to be some kind of parallel between developing countries with large volumes of illicit financial outflows, and a dependency these countries have on external debt. This means it seems that weak economies, that are highly dependent on external debt and have large amounts of this debt, seem to have the largest volumes of illicit financial outflows. Weak regulation, high levels of debt and liberalised trade markets seem to be contributing factors to the degree to which companies evade taxes and partake in tax haven activity in these regions. Another key finding was that in 2012, despite China being ranked number one in the the countries which have the largest amounts of outflows on average, it still managed to achieve large amounts growth in the last 20 years. Indicating that there is some form of indication that IFFs could be viewed as symptomatic of weak financial systems and weak economies, instead of IFFs being the core of the problem.

- Description: The term “Stokvel” originates from the rotating cattle auctions of English settlers in the Eastern Cape during the nineteen century. A Stokvel is defined as a credit union where a group of people agree to contribute a fixed amount of money to a common pool and is referred to as a rotating savings and credit association, where the contributions to a fund are given in whole or in part to each member. The goal of the thesis was to determine the “gross income” implications of the fund and its members, as well the deductibility of their expenses. An interpretative research approach was used in the research as it sought to understand and describe. No interviews were conducted for this research and the data used for the research are publicly available. The tax implications of five different types of a Stokvel were considered in relation to the research goals through the application of legislation and case law principles. The study established that a collection burial society, where funds are contributed after death, does not beneficially receive funds and it is not entitled to any deductions. The same applies to the member of that society. A contributing burial society, where funds are contributed over time, beneficially receives funds, which are included in “gross income”, and qualifies for deductions. The receipt by the member is exempt and deductions are prohibited by section 23(f). An entertainment Stokvel does not receive the contributions on its own behalf and benefit. No deductions are available to it. However, the member beneficially receives the contributions from the Stokvel, which are included in “gross income”, and qualifies for deductions. A purchasing power group, where items are purchased on behalf of members, does not receive the funds beneficially and no deductions are available to it. The members simply receive the goods they have paid for. Lastly an investment Stokvel, which invests contributions for the members, beneficially receives contributions and qualifies for various deductions. The member receives the share of income from the Stokvel for his/her own benefit. However, no deductions are available in respect of contributions.

- Description: South Africans banking sector is one of the most dominating banking sectors in Africa. The banking sector is privately owned and involves a lot of different stakeholders, who risk losing their investments. One of the stakeholders who are the bottom of the repayment chain are existing ordinary shareholders because they risk losing all their investment in the result of bankruptcy, liquidity crises or the inability of the bank to repay their shareholders. Regulators in the banking sector only protect the depositor and the stability of the banking sector but not ordinary shareholders. An internal supervisory measure called economic capital has recently received more attention because of its aim to protect ordinary shareholders and thus, existing and prospective shareholders can use its value as a protective indicator. Economic theory assumes that the higher the value of economic capital (the lower the economic capital shortfall), the lower the return on investment for existing ordinary shareholders. The aforementioned shows a trade-off between protection (economic capital) and returns. Literature by Larsson (2009) further suggests that banks are always reluctant with implementing internal measures to protect themselves because of the good regulatory regime in the sector, some banks think that they are “too big to fail” and the fact that the reserve banks are always on the standby as a bailout. The purpose of this research is to examine which of the top five commercial banks in South African actively protect their existing ordinary shareholders using the value of economic capital and possibly attract prospective ordinary shareholders, locally and internationally. The banks under study are Absa, Capitec, FirstRand, Nedbank and Standard Bank over ten years, starting from June 2009 to May 2019 and in monthly frequency. The observations totalled 120 and two models that are under the Return Series Method were in used, namely; Historical Simulation Model and Variance Covariance Model. Both models, although they were small deviations in the value of economic capital, concluded that Standard Bank protects its existing ordinary shareholders the most, followed by FirstRand, then Absa and last is Nedbank. Capitec was the only bank, after one financial shock that could not protect its existing ordinary shareholders. Moreover, evidence in the study shows a trade-off between economic capital and return on investment in the case of Capitec and Standard Bank. Standard Bank had the highest value of economic capital and second-lowest return on investment, while Capitec had the highest return on investment and lowest value of economic capital. The significant policy implication of the research is that financial institution needs to strike a balance between protection and profits; thus, a way of protecting various stakeholders. Financial shocks have proven that regulatory measures are weak and they are is need for internal measures (economic capital) which indicate how financial institution can sustain in such cases.

- Description: South Africa is a semi-arid, water scarce country. The nation has suffered a spate of severe droughts in several regions in recent years, which have significantly impacted the country’s economy. Global warming, population growth, and rising demand for water intensive products are only expected to intensify water supply problems in the future. The agricultural industry is the largest consumer of water in South Africa, accounting for the majority of total surface water withdrawals. As such, the agricultural sector is faced with complex and difficult management decisions in the face of a potential water supply crisis. The water footprint (WF) and economic water productivity (EWP) of citrus production across three river catchments located in the Eastern Cape Midlands (situated in the vicinity of the settlements of Adelaide, Cookhouse and Fort Beaufort respectively) were calculated and compared. In the long-term average (LTA), blue WF weighted across all three regions accounted for the greatest proportion of total WF (53%), followed in turn by green and grey WF (30% and 17% respectively). LTA blue and grey WF was lowest in the Adelaide region, while green WF was smallest in the Fort Beaufort region. Blue, green and grey WF were found to be greatest in the Cookhouse region. LTA EWP was greatest in the Fort Beaufort region and smallest in the Adelaide region. Of all variety groups assessed, lemons were found to have the lowest LTA crop water use and blue, green and grey WF when considering citrus production averaged across all three study regions. Satsumas has the second smallest LTA blue, green and grey WF, followed by navels, mid-season mandarins, and finally, late mandarins. Lemons had the greatest LTA EWP of all varieties, followed in turn by satsumas, late mandarins, mid-season mandarins and navels. Blue crop water use was consistently lowest in the designated wet year and highest in the dry year. However, this same trend was not necessarily true for WF findings. WF and EWP are useful indicators of water use which can be used to help guide complex water management decisions. However, these indicators are single-factor productivity measures applied in a multi-factor environment. It is therefore important that factors outside of water use are considered when making water management decisions. Moreover, it is important to examine the impact that the various components making up WF and EWP have on the resultant figures, rather than merely considering the superficial results themselves. Factors such as CWU, orchard maturity, crop choice, potential yield, climate, irrigation system, economic return, water allocation and water availability should all be taken into account.

- Description: Countries such as South Africa have attempted to leverage eHealth by digitising patients’ medical records with the ultimate goal of improving the delivery of healthcare. This involves the use of the Electronic Health Record (EHR) which is a longitudinal electronic record of a patient’s information. The EHR is comprised of all of the encounters that have been made at different health facilities. In the national context, the EHR is also known as a national EHR which enables the sharing of patient information between points of care. Despite this, the realisation of a national EHR system puts patients' EHRs at risk. This is because patients’ information, which was once only available at local health facilities in the form of paper-based records, can be accessed anywhere within the country as a national EHR. This results in security and privacy issues since patients’ EHRs are shared with an increasing number of parties who are geographically distributed. This study proposes an access control model that will address the security and privacy issues by providing the right level of secure access to authorised clinicians. The proposed model is based on a combination of Role-Based Access Control (RBAC) and Attribute-Based Access Control (ABAC). The study found that RBAC is the most common access control model that is used within the healthcare domain where users’ job functions are based on roles. While RBAC is not able to handle dynamic events such as emergencies, the proposed model’s use of ABAC addresses this limitation. The development of the proposed model followed the design science research paradigm and was informed by the results of the content analysis plus an expert review. The content analysis sample was retrieved by conducting a systematic literature review and the analysis of this sample resulted in 6743 tags. The proposed model was evaluated using an evaluation framework via an expert review.

- Description: The expansion of technological developments in all areas of society has seen governments taking advantage of new technologies to enhance public service delivery, disseminate information and promote participation by the public in government decision-making. This phenomenon is known as electronic government, or e-Government. However despite the socio-economic benefits inherent in the implementation of e-Government systems, an overwhelming number of government projects – particularly in developing countries – struggle to successfully implement e-Government systems. e-Government project failure is more pronounced in developing countries, with more than half of these projects either partially or completely failing. The failure of e-Government projects undermines government investments, as well as the potential socio-economic benefits that could be realised by the citizens. Arguably, while the failure or success of an e-Government project is attributed to a myriad of factors, low user adoption is one of the key factors that contribute to e-Government project failure. Therefore this thesis seeks to investigate the phenomenon of low e-Government user adoption and determine whether the use of an Agile system development approach can positively influence e-Government user satisfaction as well as buy-in and adoption. A Mixed-Methods, multi-case study approach was used through the perspective of Post-Positivism. The researcher examined four (4) South African e-Government projects – using an online questionnaire and in-depth interviews with members of the system development team – to determine whether the use of an Agile approach has merit in enhancing e-Government user adoption. The use of a Mixed-Methods approach allowed for data triangulation so as to verify the findings; while the use of multiple case studies enabled for cross-case analysis. The findings indicate that the use of Agile practices, as listed in the proposed Agile-informed User Engagement Guidelines, can ensure that the e-Government system developed meets user needs; and, that users are satisfied with, and make use of the e-Government system. However since most large e-Government projects make use of a traditional Waterfall development approach, it is recommended that the Agile practices (proposed guidelines) be incorporated into the structured Waterfall approach – to create a hybrid, or blended system development approach. In conclusion, the use of the proposed Agile-informed User Engagement Guidelines can enhance e-Government user adoption; and, subsequently, contribute towards nurturing the success of e-Government projects.

- Description: The increase in obesity is a global crisis that is prevalent in both the developed and developing economies, including South Africa. It endangers the health and threatens the life of many people. Sugar-sweetened beverages have become the key target in the fight against obesity, in preference to other foodstuffs that contain added sugar, because of the poor nutritional value they contain and harm they cause if consumed excessively. The Minister of Finance announced in the 2016 Budget Speech, that a proposed tax on sugar-sweetened beverages would be introduced in South Africa and would be implemented in April 2017, but the anticipated date is now 1 April 2018. The thesis examined the possible success of this proposed tax in South Africa, using as a benchmark the process followed prior to implementing the tax and the experience of selected foreign countries that have implemented the tax, one country subsequently abolishing it, and another country considering implementing it. Additionally, the research analysed the success of the existing excise taxes levied on tobacco and alcohol in South Africa, in attempting to predict the possible success of the proposed tax. The success of the proposed tax is, however, threatened by the emergence of illegal markets that offer the targeted products inexpensively, particularly if similar restrictions and laws do not exist in bordering countries. The research was carried out by means of the analysis of journal articles, information from the selected countries’ revenue authorities’ websites, National Treasury publications, commentaries by experts and publications by professional organisations and firms. Overall, the proposed tax has been successful in curbing obesity and high sugar intake in other countries. Similarly, the excise taxes on tobacco and alcohol have been successful in reducing the consumption of targeted products in South Africa. These successes have been realized through a collaborated effort and employing a multi-faceted approach, including advertising restrictions. Nevertheless, the proposed tax is popularly criticised for its regressive nature and the potential job losses that are associated with it.
