- Description: Currently there is limited research investigating the football related abilities of youth South African individuals. Populations from North and South America, Europe and Asia have been extensively covered in terms of their anthropometric characteristics, physical abilities, technical competency, tactical understanding as well as various personality traits. In describing these details, and especially how each is affected during the ageing and pubertal process, a more informed understanding of the talent development systems is created. A holistic approach to talent development is required to effectively and efficiently produce elite level footballers. An important consideration is the unique socio-economic environment many youth footballers experience which may impact on the talent development process. The present study therefore sought to quantify the anthropometric characteristics and the physical ability level of youth South African footballers from Local Football Association in Makhanda in the Sarah Baartman Region of the Eastern Cape province. In order to achieve this a two-factorial design was used with age and maturity status as independent variables. Anthropometric characteristics were tested by finding the height, weight, body mass index and total fat percentage of participants. Physical ability was determined by results for aerobic capacity, power, acceleration, speed and agility. All tests were football specific and had been widely used in a variety of footballing studies. Additional demographic and socio-economic information was also recorded. A total of 136 participants were placed in their respective Under 11, 13, 15 or Under 19 age groups, while the maturity status of 96 participants were stratified into five distinct categories. Statistical analyses was conducted using p-value significance, with appropriate Tukey post-hoc tests administered when necessary, while effect sizes were calculated using Cohen’s d. Significant changes and practical effect sizes were present for nearly all dependent variables when either stratified by age or by maturity. Total fat percentage was the only dependent variable which was not influenced by either age or maturity. Age and maturity effect sizes for total body fat percentage indicated practical changes present which did not occur during statistical analysis. The present results indicate poor values when compared to normative data or that of other football playing study populations. Further longitudinal research is required to better understand individual growth rates for youth South African footballers, particularly from the Makana region. Implications of the thesis may determine long term development pathways, while the delayed maturity rate is a critical finding which needs to be further researched.

- 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: This thesis investigates whether there is a relationship between education, economic growth and global competitiveness and whether there is a relationship between South Africa’s current throughput rates in institutions of higher education, and its economic growth and global competitiveness. Economic growth is defined as a country’s ability to improve the life of its average citizen based on the strength of its economy. As such, it is increasingly important for a country to assess the factors that contribute to the improvement of their economy, which will ultimately result in its economic growth. Global competitiveness is an indication of how countries are able to provide for their people internally, as well as participate in the international market. To this end, economic growth and global competitiveness are two proxies that can be used to demonstrate the economic wellbeing of a country. Considering that prosperity under economic growth and global competitiveness of a country are driven by its people, one of the aims of this thesis was to investigate whether there is a relationship between education and economic growth and global competitiveness. Considering the recent demand in free education in South Africa, it is also important to understand whether there is a relationship between South Africa’s current throughput rates at higher education institutions and its economic growth and global competitiveness. Bearing in mind the political past which has led to inequality in the country, it is important to understand which types of education contribute to the economy and which types need to be further supported in order to increase the country’s economic productivity. Therefore, an additional aim of the thesis was to determine the relationship between South Africa’s current throughput rates in institutions of higher education, and its economic growth and global competitiveness. To address the aforementioned aims, data were collected from various open access online repositories. All the data were collated and numerous general linear models were constructed and tested to determine the different relationships as per the two aims. The results reveal that secondary school education had the highest impact on economic growth and global competitiveness on a global scale. This could be attributed to the fact that secondary school graduates tend to make up the largest part of the general workforce and as such, would make up a substantial proportion of the economy. Regarding South Africa, the only significant relationships were between green cluster universities (universities that focus on both research and technical training) and global competitiveness. Overall average throughput rates in all academic institutions were low; this could indicate that perhaps there are issues within the higher education system itself that need to be addressed in order to increase the throughput rate. From a managerial perspective, the results of this research stress the importance for the government to further investigate this area of study, as the call for free education becomes more prominent. The low throughput rates seem to suggest that the government is spending substantial amounts of money on students who do not always complete their studies. More research needs to be done to assess the root of the problem in South Africa’s tertiary education system, in order to ensure that this aspect increases its positive contribution towards the country’s economic growth and global competitiveness.

- Description: There has been a rapid increase in atmospheric CO2 concentration, from pre-industrial values of 280 ppm to more than 400 ppm currently, and this is expected to more than double by the end of the 21st century. Studies have shown that plants grown above 600 ppm tend to have an increased growth rate and invest more in carbon-based defences. This has important implications for the management of invasive alien plants, especially for the field of biological control which is mostly dependent on herbivorous insects. This is because insects reared on such plants have been shown to have reduced overall fitness. Nevertheless, most of the studies on potential changes in plant-insect interactions under elevated CO2 are based on agricultural systems, with only a limited number of these types of studies conducted on alien invasive weeds. However, climate change and invasive species are two of the most prevalent features of global environmental change. Therefore, this also warrants active research and experimental studies to better understand how these systems will be affected by future climates. Thus, the aim of this study was to investigate the effects of elevated atmospheric CO2 on the biological control of four invasive aquatic weeds (Azolla filiculoides, Salvinia molesta, Pistia stratiotes, and Myriophyllum aquaticum). These species are a threat to natural resources in South Africa but are currently under successful control by their biological control agents (Stenopelmus rufinasus, Cyrtobagous salviniae, Neohydronomus affinis, and Lysathia n. sp.). To achieve this, the selected plant species were grown in a three-factor experimental design in winter (CO2 X nutrients X herbivory), and another two-factorial design in summer (CO2 X herbivory). Atmospheric CO2 concentrations were set at ambient (400 ppm) or elevated (800 ppm), as per the predictions of the IPCC. As per my hypothesis, the results suggest that these species will become more challenging in future due to increased biomass production, asexual reproduction and a higher C: N ratio which is evident under high CO2 concentrations. Although the biological control agents were in some instances able to reduce this CO2 fertilisation effect, their efficacy was significantly reduced compared with the levels of control observed at ambient CO2. These results suggest that additional biological control agents and other management methods may be needed for continued control of these invasive macrophytes, both in South Africa and further afield where they are problematic.

- Description: ARF GTPases are key regulators of the secretory and endocytic pathways. ARF1 is involved in the secretory pathway. ARF1 has been implicated in the endoplasmic reticulum to Golgi transport, function of the Golgi apparatus and transport from the trans-Golgi network to endosomes. ARFs cycle between active GTP-bound and inactive GDP-bound conformations. GDP/GTP cycling is regulated by large families of guanine nucleotide exchange factors (GEFs) and GTPase activating proteins (GAPs). ARF GEFs facilitate the activation of ARFs by mediating the exchange of GDP for GTP, while ARF GAPs terminate ARF function by stimulating the hydrolysis of the terminal phosphate group of GTP. Based on existing evidence gained from gene manipulation and cell biological investigations, ARF1 has been shown to be fundamentally important for cancer cell proliferation and metastasis and may be a promising target for the development of anti-cancer drugs. Additionally, the conservation of ARFs in eukaryotic organisms leads to an interesting question of whether a single drug target can be used to target multiple diseases. In this case, can a human cancer drug employed for cancer therapy be used in anti-malarial drug therapies? To confirm the drug target status of ARFs using chemical validation experiments, novel inhibitory compounds are needed. This requires the development of complex in vitro protein- protein interaction assays that can be used to screen chemical libraries for ARF GTPase inhibitors. In this study, we developed a fluorescence resonance energy transfer (FRET) assay and a novel in vitro colorimetric plate-based assay to detect the activation status of truncated human and Plasmodium falciparum ARF1. In the case of the FRET assay, active (GTP-bound) and inactive (GDP-bound) ARF1 could be distinguished with Z-factor values >0.5, suggesting that further development of the assay format to identify GEF and GAP inhibitors may be feasible. In the case of the colorimetric assay, robust signals could be detected and the assay was useful for detecting the activation status of ARF1. However, although the activation of ARF1 by the Sec7 domains of the BIG1 and ARNO was detectable, signals were not robust enough to employ in screening campaigns.

- Description: My novella tells the coming of age story of a young woman battling the trauma of objectification. It explores the intimate relationship between a woman and a man, the young and the old, and the camaraderie between women. Having spent the greater part of her youth in various parts of the world, my protagonist faces the stark reality of returning home to her native country. This triggers an angst which causes her to leap between lived experiences and memories. An elegy on how difficult it is to love while dragging the long shadow of shame, it uses short prose and prose poetry to reveal the intimacies and intricacies of self hate and clandestine romances, and to unravel the complexities of memory and forgetting. Built from non linear fragments it seeks to refuse cliches regarding love and to question easy assumptions around gender, family and the innocence of youth. I draw inspiration from Vita Sackville West’s’ All Passion Spent , which eloquently portrays the placid and flickering thoughts of an old woman taking leave from the frivolity of youth. I’m similarly inspired by the sincerity and confessional aspects of Virginia Woolf and French poet and photographer Alix Roubaud ’s journals and Van Gogh’s letters, as well as Lydia Yuknavitch, Max Porter and Elena Ferante’s autobiographical fiction. I also draw from J’Lyn Chapman’s chapbook A Thing of Shreds and Patches and finally Dostoevky’s Notes from Underground , for their blurring of life and writing, and their exploration of grief and death as a lingering thought, together with the oppressive urge to create. In addition I’m inspired by the poetry of a new generation of South African female writers like Vangile Gatsho.

I draw inspiration from Vita Sackville West’s’ All Passion Spent , which eloquently portrays the placid and flickering thoughts of an old woman taking leave from the frivolity of youth. I’m similarly inspired by the sincerity and confessional aspects of Virginia Woolf and French poet and photographer Alix Roubaud ’s journals and Van Gogh’s letters, as well as Lydia Yuknavitch, Max Porter and Elena Ferante’s autobiographical fiction. I also draw from J’Lyn Chapman’s chapbook A Thing of Shreds and Patches and finally Dostoevky’s Notes from Underground , for their blurring of life and writing, and their exploration of grief and death as a lingering thought, together with the oppressive urge to create. In addition I’m inspired by the poetry of a new generation of South African female writers like Vangile Gatsho.

- Description: This thesis sought to identify and isolate the impact of the minimum wage in the hospitality industry of Polokwane. To achieve this, qualitative research methods were used. These methods enabled an in-depth understanding of minimum wages. Thus in-depth, semi-structured interviews were conducted as they provided detailed information by enabling the researcher and the participant to have an informal, but expressive conversation about the minimum wage. Contrary to the assumptions of orthodox economics, which claim minimum wages create a ‘shock’ resulting in job losses, this research found that the minimum wage was absorbed causing few disruptions in existing work and employment relations in the selected establishments. This capacity to absorb the minimum wage is largely the outcome of informal labour relations policies and practices.

- Description: This dissertation endeavours to unpack and understand the impact of the minimum wage on the hospitality industry with a specific focus on Grahamstown. The areas of impact that are of immediate interest were the impact on poverty and industrial relations. In operationalising this research, a qualitative research approach was adopted. The overall design of the study was a case study in a bid to ensure deeper insights may be extracted from semi-structured interviews that were then thematically analysed. Theoretically, the study was guided by the understanding of citizenship as articulated by Mamdani as well as Keynesian theory. The central theme when exploring the minimum wage in relation to poverty is that the minimum wage that is currently paid is enough to aid workers and their families in escaping abject poverty, however, it does not go far enough to further ensure that they totally escape poverty as measured by the Upper Bound Poverty Line. The inadequacy of the minimum wage in ensuring that people are pushed out of poverty would then mean that their claims to citizenship are compromised and the quality of life they can access is often below what would be readily accepted of a citizen of South Africa. Lifestyle entrepreneurs offer an alternative approach to doing business that can see higher pay as further entrench claims to citizenship. The central case around industrial relations is that the impact of the minimum wage is indeterminate for two reasons. Broadly speaking, the impact would need to be reviewed at a macro-level and not simply within the impacted sectors. This is the various interconnected value chains that could feel indirect impacts at the initiation of a minimum wage. Further, the impact such changes has to individual firms is also indeterminate as employers have a range of choices that they can adopt in absorbing the impact of a minimum wage, which may include simply increasing the price the end consumer pays or retrenching some staff members. However, the choice that employers would make in this context is not predetermined but rather would vary between firms due to the very specifics of each firm.

- Description: First-generation African students contend with psychosocial, structural, educational background and financial struggles to gain access to university. The first-generation students exercised their available resources and power, agency and acquired skills to negotiate their journey and entrance to university. They had to figure out for themselves how to navigate a daunting and complex path to university without relying on the knowledge and informative engagement with previous older familial generations who had the experience of attending university. They are a testimony of a generation of young people who have the resilience and grit to compensate for the structural deficits they have and experienced through their disadvantaged educational systems and their financially disadvantaged backgrounds. Although one would expect that teachers would automatically be the first encounter a high school student has of acquiring information on how to gain access to university, many of the previously disadvantaged school teachers are simply too inundated with work to be able to facilitate this process. First-generation students found themselves mostly having to look beyond the parameters of the classroom to acquire these resources. Following a qualitative approach of narrative enquiry, five African students with life experience of being first-generation Rhodes University students whose mothers were or are domestic workers, narrated their personal stories. A first-generation student’s agency, negotiation and navigation through obstacles, struggles and setbacks in the backdrop of having mothers who were/are domestic workers who socialised their children in a specific ideology to value and pursue education are the foundations for this narrative enquiry. This research provides a framework for investigating the concept of adequate and appropriate university preparedness to address the inadequate resources that previously disadvantaged schools have in terms of preparing their students to compete (in often times with more advantaged students) to gain access to university. These first-generation students did not come from educational environments where career counselling or aptitude tests are done to better equip them for entrance into university and appropriate subject and degree choice. Several common traits emerged that give perspective to the narrative of the journey that first-generation students’ had to endure and overcome to gain access to university.

- Description: On 4 August 1983, a thirty-three year-old army captain seized power in Burkina Faso and embarked on what can be described a revolutionary journey. Over the next four years, until his assassination in 1987 the government, led by Captain Thomas Sankara, attempted to redeem Burkina Faso from the clutches of neo-colonialism. Through popular mobilisation and organisation, infrastructure (schools, hospitals, bridges) was built, millions of children were vaccinated and diseases such as river blindness were eliminated. Women, long-subjugated by patriarchal systems took up space and led their own initiatives in freedom, including holding senior roles in the public service. On the international stage, practical solidarity was extended to countries either fighting or threatened by neo-colonialism despite the fact that Burkina Faso was poor and was itself threatened by France and her lackeys. What Sankara inherited in August 1983, twenty-three years after Burkina Faso’s independence, was a fragile neo-colonial state which was not allowed by dominant imperialist interests to set an example of what true independence means. So, in just four years, it was all over. Sankara was assassinated by his comrades and the revolutionary project he had led came to a halt. The tragedy of Sankara was the tragedy of all those attempts at revolution which occur before mass movements have had the opportunity to develop and organise themselves independently of the state. Despite this, it is apparent today that Sankara has been influential on current political movements and parties in Africa, from Burkina Faso to South Africa. One of these political movements is the Economic Freedom Fighters (EFF) in South Africa. This half-thesis is an investigation of Sankara’s political thought. It also examines the extent to which his answers to questions of nationalism and pan-Africanism both matched and differed from his predecessors. To accomplish the latter, a brief but critical analysis of the writings of Amílcar Cabral, Frantz Fanon, Kwame Nkrumah is made.

- Description: The study explored the potential of Geography fieldwork projects to develop learners’ action competence in response to social-ecological problems in two schools in the Omusati and Oshana Education Regions. The study investigates ways in which learners’ activities create an opportunity for them to act for the environment. That is, to investigate ways in which learners can be shaped into environmentally literate citizens who act for the environment. A total of 43 grade 10 learners and two grade 10 Geography teachers participated in this qualitative, interpretive case study. Data was generated through document analysis, focus group interview with learners, semi-structured interviews with educators, and participant observations. Such data were analysed into three phases, first inductively and then abductively using Jensen’s (2004) Investigations, Visions, Actions and Change (IVAC) model to produce analytic statements that form the basis of the research findings. The study found that Geography fieldwork projects foster understandings of environmental problems in a local area. Through fieldwork projects, schools initiate indirect environmental actions, however, some environmental problems are too large or complex to be resolved by the actions initiated by learners. Based on these findings, the study identifies Geography fieldwork as an opportunity to create a community of practice in effort to address socioecological concerns. The study further recommends that learners should be allowed to engage with both social investigative actions and technical, scientific investigative actions when doing project work.

The primacy of illicit financial flows (IFFs) in developing countries: a comparative study analysis of South Africa and China

- 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: This dissertation explored the views of academics who teach and research in the area of Industrial/Organisational Psychology in South Africa about the utility of the field in engaging with the post-1994 South African workplace, thereby remaining relevant. When it emerged as a field of study and practice, Industrial/Organisational Psychology research’s aim was to inform workplace practice and contribute to the betterment of society. It appears as if today this research is deemed irrelevant to the workplace and society, with many practitioners relying on their own knowledge and irrelevant repetitive one size-fit-all Euro-American developed theoretical framework and research evidence to solve the challenges of the post-1994 South African workplace, and to serve its society. The latter propelled the researcher to ask broadly the question of relevancy of the discipline in meeting the demands of the post-1994 South African workplace. Face-to-face, semi-structured interviews were employed to collect data on 8 senior and younger generations of academics in 3 different universities. The collected data was analysed using Braun and Clarke’s 6 steps of thematic analysis. The data and study as a whole was approached with a ‘post’-colonial lens and a Contexualist paradigm in order to contextualise in the present time the past nuances that arose in our country during the colonial and apartheid eras. Themes discussed seemed to indicate a lack of research focus by academics and their students due to limited time and stringent bureaucratic publication structures present both within their universities and outside. When it came to the discipline as seen through the lens of the data and what this suggested in terms of speaking to post-1994 workplace organisational psychological problems, the study found that the findings arising out of the research in I/O psychology appear to be of little relevance to whom they are currently aimed, leading to the idea of these studies acting as a change agent in the workplace and society to fall to the wayside.

- Description: This research was a Case Study on the role of Flexible Working in achieving a Work – Life Balance, based on the Information Technology Consultants of Kestrel Business Solutions – a company based in London, the United Kingdom. The study set out to determine what aspects of flexible working can reduce work - related stress; home - related stress; improve personal wellbeing; identify the pitfalls of flexible working, and to recommend mitigating actions. The literature review identified five different, but complimentary theories that included: The Spill over Theory; Balanced Theory; Resource Based Theory; Compensation Theory and the Wellness Theory to unpack and explore the concept of Work - Life Balance. The study followed a predominantly qualitative methodology approach and used thematic analysis to identify key ideas from the data. Interviews and questionnaires were used to obtain data from the respondents, in addition to being a data triangulation exercise. From a population of 10 subjects - purposeful sampling was used to select a sample of 10 respondents - made up of 3 males and 7 females. All respondents were employees of Kestrel Business Solutions. 6 respondents were interviewed and given questionnaires to fill out. 6 face to face interviews were conducted, and 6 questionnaires completed until saturation was achieved - indicating a survey response rate of 100%. The results from the data collection generally showed how aspects of flexible working like telecommuting, flexitime and homeworking ultimately helped the employees to achieve a Work-Life Balance - by primarily influencing how they balanced their work, home, and personal commitments. Importantly, the study also identified pitfalls of flexible working; like employees feeling isolated and the pressure to perform. Potential mitigating efforts identified in the study included, providing more company support and education for flexible working initiatives. The study concluded by acknowledging the limitations of the study, which included time constraints and the small population, and sample size of the study. In its conclusion, the study identified recommendations for future studies like: increasing the population and sample size, and devoting more time to the study, for more generalized and conclusive findings.

- Description: This research was a Case Study on the role of Flexible Working in achieving a Work – Life Balance, based on the Information Technology Consultants of Kestrel Business Solutions – a company based in London, the United Kingdom. The study set out to determine what aspects of flexible working can reduce work - related stress; home - related stress; improve personal wellbeing; identify the pitfalls of flexible working, and to recommend mitigating actions. The literature review identified five different, but complimentary theories that included: The Spill over Theory; Balanced Theory; Resource Based Theory; Compensation Theory and the Wellness Theory to unpack and explore the concept of Work - Life Balance. The study followed a predominantly qualitative methodology approach and used thematic analysis to identify key ideas from the data. Interviews and questionnaires were used to obtain data from the respondents, in addition to being a data triangulation exercise. From a population of 10 subjects - purposeful sampling was used to select a sample of 10 respondents - made up of 3 males and 7 females.

- 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: Taxonomy is a tool that plays a crucial role in the implementation of effective management assessments, the ability to identify different fish species and their life stages, and create effective conservation strategies. Recent years have seen an increase in the discovery of cryptic species which could have an effect on how we implement conservation strategies, increasing the importance of accurate taxonomic assessments. The southern African topminnows of the genera Micropanchax and Lacustricola (Family Procatopodidae) include several species of egg-laying fishes that live in the marginal areas of rivers and lakes throughout the river systems of southern Africa in separated and connected populations. It was recently discovered that these populations showed subtle differences in their morphology and colouration, which led to the belief that new and cryptic species may be present. Previous studies of the Procatopodidae relied heavily on phylogenetic analyses that drew on morphological traits without reliance on molecular methods of analysis. A few of the taxonomic issues were resolved through these limited studies but ultimately the taxonomic status of the Procatopodidae remained poorly understood. Furthermore, these studies had not been updated in recent years and hence the benefits of new technology had not been brought to bear on the issues. A multi-gene analysis using standard phylogenetic methods and five molecular markers (mitochondrial cytochrome C oxidase (COI), mitochondrial cytochrome b (cytb), mitochondrial 16S ribosomal RNA (16S rRNA), nuclear 28S ribosomal RNA (28S rRNA) and mitochondrial Tyrosine Kinase (X-src) (TyrK)) allowed phylogenetic trees to be made which demonstrated clear relationships within Micropanchax and Lacustricola of southern Africa and the out-groups used in the analysis. The inference trees showed that Micropanchax johnstoni was represented by three clades and was shown to be polyphyletic while Micropanchax hutereaui, which was represented by two clades, and Micropanchax katangae, which was represented by one clade, were monophyletic. The two species of Lacustricola, L. myaposae and L. macrurus showed very close relationships to Micropanchax and it is suggested that these two species be transferred to Micropanchax, leaving Lacustricola to only be found in central Africa.

- Description: This thesis is motivated by my experience of Inzilo: Ngoba ngihlala kwabafileyo, a live performance by South African visual artist Buhlebezwe Siwani. The performance took place at Michaelis Galleries, University of Cape Town (UCT), as part of a group exhibition Between Subject and Object: human remains at the interface of art and science (2014), which accompanied the Medical Humanities in Africa Conference (from 28 – 29 August 2014). As an entry into my discussion, I describe how Siwani’s performance makes use of death and burial ritual in what seems to be an intention to make art that is (re)presenting an activity of reality to invade and control the sphere of feelings, emotions and a sense of ceremony that is dependent on both ritual and rites of the performance. I grapple with the fact that I experienced a ritual performance in a gallery space. Furthermore, I question how walking out of the performance I thought of the lines between art and/or life. The role of ritual in my thesis explores the symbolic meanings, powers and intentions of ritual rites in Africa. This reflection maps out historical locations that are relevant to the major debates, definitions, themes and the experiences of ritual as part of academic research. From Siwani’s practice as an artist and isangoma to other expressions in the fields of history, sociology, religion, feminism, to mention a few, my thesis is an enquiry that engages ritual and performance art theory and scholarship. Through a qualitative analysis, my methodology rejects a chronological, thematic and discipline centered research. Rather, I use a multidisciplinary approach based on critical visual analysis as knowledge creation in the visual arts, for example archives, documentation, performance, text, video, installation, painting, sculpture, etc. The findings suggests that the role of ritual in performance art is not a singular exploration, nor is it based on separating ritual and performance art. The results further reveal that ritual in performance art is not a reenactment of patterns and human behaviours, nor is the notion of reenactment used to denote the myriad meanings and functions of re-performing historical ritual events into performance art. Throughout, my thesis provides a focus that demonstrates the significance of how ritual in performance art has a profound subjective (personal or individual) and collective holistic way of serving human and spiritual needs, and that of creating an environment that is open to the content and context of art as it relates with traditional African religious practices, beliefs and knowledges. Focus is given to three major themes that make up the three chapters of my research: firstly, I reflect on death as personified by Siwani’s performance Inzilo: Ngoba ii ngihlala kwabafileyo and her role as isangoma. Here death is used to draw specific attention to the body in process of embodied presence and absence of physical and spiritual worlds. Secondly, drawing on Siwani’s concept of secrecy and boundaries of concealing and revealing rituals meanings and powers as isangoma, I question the role of secrets, which highlights the significance of bodies (human and natural sites of ritual) in ritual performance. Finally, the idea of a trace is explored. The intersecting use of a trace as the thinking-making-doing of ritual in performance articulates a connected thread that sets in motion the trace of ritual (installation, image and marked space pf ritual) as an afterlife that offers a continued space of processual ceremony for multiple effective encounters and movements..

- 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: Background and aim: Flight attendants forms a significant part in 24-hour aviation industry. Flight attendant fatigue is a significant problem in the aviation industry as it continues to jeopardize the ability to fulfil important safety and security roles which is critical in performance duty of a flight attendant. However, little attention has been accomplished to the workload, working conditions and fatigue of flight attendants crew in transport aircraft. In addition, there is currently less research that have also embraced the problematic of smaller regional/commercial operation (short-haul flight operations) inducing fatigue among short-haul flight attendants as the nature of this operation are often characterised with high productivity expectations in a demanding environment with high time pressures resulting in high workloads and fatigue. Thus, flight attendant fatigue and workload is a worldwide challenge in this operational environment and less attention has been given to the determining factors. Therefore, the aim of the study was to determine the workload factors contributing to flight attendant fatigue during short-haul flight operations. Methods (System analysis): To achieve the research aim, the work system analysis, based on the Smith and Carayon-Sainfort model was chosen as the main research approach which was conducted in two ways; based on existing literature and secondly based on expert interviews. This method provided a systemic aspect to understand the whole work system of flight attendants work during short-haul operations in order to identify all the contributing factors to flight attendant fatigue and workload. Results: The literature analysis and the data from the expert interviews highlighted significant findings to flight attendant fatigue and workload. The reasons for flight attendant fatigue operating short-haul flights can be found at organizational, task, individual, environmental levels and tools and technologies and due to the interaction of the factors. The main factors of flight attendants’ fatigue are thought primarily as a function of scheduling due to irregular, mixed schedules with early starts and late finishes, extended duty days (long working hours), as well as high workload, due to the short turnaround flights, the number of sectors flown in a single duty period and duty length and high jobs demands. In addition, flight duty and rest regulations, confined work space in the cabin, vibrations, noise and lighting, sleeping in an unfamiliar environment, family responsibilities all add to additional stress placed on the body which can influence workload and sleep and consequently influencing fatigue. Conclusion: Overall the study determined that flight attendant fatigue is a significant problem in modern industry of short-haul operations. Using this systematic approach (work system analysis based on the framework of the work system model developed by Smith and Carayon-Sainfort (1989) allowed for an accurate representation of the complexity of flight attendant work environment in short-haul aviation industries, thus contributed to an increased understanding of fatigue and risk factors that span the entire work system and aid in identifying the patterns in combination of work system variables that are associated with increased risk to flight attendant fatigue. Overall flight attendant fatigue is a product of interactions with the short-haul environment. It can have a negative impact on safety, performance and well-being. Therefore, it needs to be managed and dealt with in the near future.

The main factors of flight attendants’ fatigue are thought primarily as a function of scheduling due to irregular, mixed schedules with early starts and late finishes, extended duty days (long working hours), as well as high workload, due to the short turnaround flights, the number of sectors flown in a single duty period and duty length and high jobs demands. In addition, flight duty and rest regulations, confined work space in the cabin, vibrations, noise and lighting, sleeping in an unfamiliar environment, family responsibilities all add to additional stress placed on the body which can influence workload and sleep and consequently influencing fatigue. Conclusion: Overall the study determined that flight attendant fatigue is a significant problem in modern industry of short-haul operations. Using this systematic approach (work system analysis based on the framework of the work system model developed by Smith and Carayon-Sainfort (1989) allowed for an accurate representation of the complexity of flight attendant work environment in short-haul aviation industries, thus contributed to an increased understanding of fatigue and risk factors that span the entire work system and aid in identifying the patterns in combination of work system variables that are associated with increased risk to flight attendant fatigue. Overall flight attendant fatigue is a product of interactions with the short-haul environment. It can have a negative impact on safety, performance and well-being. Therefore, it needs to be managed and dealt with in the near future.
