- Description: The South African abalone, Haliotis midae, is a commercially important species of mollusc which contributes significantly to the value of the South African mariculture industry. One of the primary challenges experienced by abalone farmers is the consistent production of juvenile abalone (spat) in sufficient volumes to keep stocking farms and facilitate expansion of the industry. One of the key production bottlenecks of H. midae is achieving adequate levels of larval attachment and metamorphosis (settlement). The larvae of H. midae are settled on polycarbonate plates which have been pre-conditioned with biofilms in seawater which is pumped ashore onto farms. The seasonal variability in settlement success reported by hatchery managers in South Africa is hypothesised to be as a result of different diatom species compositions colonising the settlement plates at different times of the year, with settlement success being lowest during the winter months. The following study investigated whether the addition of conspecific mucous to biofilms could result in elevated settlement success, and whether there was potential for sterilisation of this mucous. A novel method of mucous application, spraying it onto the plates as opposed to pre-grazing, was tested in settlement assays and the trials revealed the following results: • The addition of H. midae mucous induced significantly more larvae to attach to settlement plates, when mucous was harvested around the spawning season. • Elevated attachment of larvae on mucous treated plates did not result in more post-larvae occupying the plates at the end of trials, and increased mortality is likely attributed to introduction of pathogens in conjunction with mucous. • No increase in the final proportion of settled larvae which had metamorphosed or the rate at which they metamorphosed was observed between mucous application treatments and biofilm only treatments. Subsequent trials assessed whether methods of mucous handling could reduce the biosecurity risk associated with mucous use, and so mucous was either UV irradiated or autoclaved. These trials revealed the following findings: • No difference in attachment was seen between any treatments, including the untreated mucous. This is contrary to the findings of our initial experiments and illustrates that the attachment-inducing properties within mucous may be seasonally expressed. ii • Numbers of observed larvae/post-larvae on plates applied with UV and autoclaved mucous where less stable than biofilms only, especially in the second trial, illustrating that mucous still presents a biosecurity risk even after undergoing these handling methods as it may act as a substrate on which pathogenic bacteria could colonise. , Thesis (MSc) -- Faculty of Science, Ichthyology and Fisheries Science, 2021

- Description: The key research problem addressed in this project is: how does the strategic decision making of firms affect an economy? While this is a difficult question to answer, insights may be gained through the use of computational techniques such as agent-based modelling (ABM). An agent-based model is developed that simulates micro-level economic interactions between individuals and _rms in different markets, resulting in emergent macro-level features. Technological progress is an important determinant of economic growth and has been decomposed into two complementary factors: knowledge and technological sophistication. The model is used to explore the long-term, macroeconomic consequences of _rms investing more heavily in knowledge development. The simulations show that a shift towards a knowledge-based economy (KBE) has an insignificant impact on GDP over the long-term. However, the shift does produce a significant increase in unemployment. The higher unemployment is shown to be particularly high for the unskilled sectors of the population. It is therefore paramount that companies embark on skills development, training and educational initiatives when following a path of technological and knowledge innovation. A transformation of the education system to one that is inclusive, focused on quality, adaptive, encourages creativity, aligned with the needs of industry, and stimulates R&D is crucial. Without a coordinated strategy between industry, academia, and government in attempts to achieve a KBE, economic growth may be constrained, while the levels of unemployment, inequality and poverty may deteriorate. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2021

- Description: Background: Humans have a long history of using the marine environment in multiple ways and continued use has led to a decline in the ecosystem services provided by marine systems in many places. In addition, human activities have steadily increased with time and advances in technology, further increasing impacts on marine systems. To understand and manage these impacts, we need to assess the spatial distribution and intensity of human activities in the marine environment, and quantify, where possible, their cumulative impacts on marine ecosystems. The spatial consideration of human activities and their associated impacts is important for conservation planning, Integrated Ocean Management and Marine Spatial Planning (MSP) initiatives. The main deliverable of this research study was to develop a cumulative impacts layer of human activities in Algoa Bay, South Africa, to support the Algoa Bay Marine Spatial Planning Project. Objective and Relevance: This research analyses the spatial impacts of human activities on the Algoa Bay marine environment (excluding the seashore). Algoa Bay is located on the south coast of South Africa in the Eastern Cape. The research explores stakeholders' perceptions of their knowledge of the human activities that take place in the bay. This research is informed by an expert-based geographical information systems (GIS) approach and cumulative impact assessment in order to map the spatial impacts of the activities as part of marine spatial planning. "Experts" were defined as stakeholders that contributed valuable knowledge of the human activities and their impacts; this definition of expert included "professional" and "non-professional" contributors to knowledge. The spatial aspect of the research is a significant contribution to the field as it will help inform decision-making in the Algoa Bay Marine Spatial Planning Project. Design and Methods: A mixed-method approach was used to generate data. A snowball sampling approach was used to identify research participants from key informants. Primary data were collected through questionnaire surveys, interviews and a focus group. Secondary data sources consisted of GIS data and reports from scientific organizations. Findings and Conclusion: The research findings indicate that the top three pressures that cause the greatest impact on the Algoa Bay marine environment are fishing, pollution and shipping. The cumulative impact of these activities was highest near harbours in Algoa Bay. The marine ecosystems that were most impacted by pressures were the Agulhas Island and the Agulhas Mixed Shore. The Warm Temperate marine ecosystems had fairly low cumulative impacts. The research findings indicate that there is a complex mix of human activities that impact the marine environment. This research supports the findings of other researchers that reveal that the highest cumulative impact is in areas closer to the coast and harbours owing to high population densities. Value of Study: This study builds onto the existing data by expanding the knowledge base and including more stakeholders to integrate as many human activities as possible and bring a holistic picture of the ocean's uses to inform MSP in Algoa Bay. , Thesis (MSc) -- Faculty of Science, Geography, 2021

- Description: This case study of Fort Cox Agriculture and Forestry Training Institute explored the sustainability focus in water management and curriculum practices. I was inspired to develop a deeper understanding of current water management and curriculum practices at Fort Cox with fellow academics involved in the teaching of water dependent curricula, students who were enrolled in water dependent subjects, and support staff involved in water management practices around campus. My initial assumption was there was a practice disconnect or mismatch between water management practices and the stated curriculum requirements at Fort Cox. To develop a deeper understanding and possible responses, the study adopted the Practice Architectures Theory (PAT) developed by Kemmis (2009) and Kemmis, McTaggart and Nixon (2013). A supportive theory was also considered in the form of the action learning process developed by Marquardt (2007), which was aimed at bringing people together in an attempt to respond to water management practice concerns in their context. Practice Architectures Theory was used with the view to understand the ‘sayings, doings, and relatings’ regarding water management and curriculum practices at Fort Cox, in particular around Irrigation, Soil and Water Conservation subjects and the other water dependent subjects. Kemmis et al. (2013) suggested that practices come into being because people do not act alone but as a collective, and bring them into being. In practice, individual understanding and action are orchestrated in collective social-relational projects. A qualitative case study approach was used to solicit data using different techniques namely workshops, semi-structured interviews, document analysis, observations and Unit-Based Sustainability Assessment Tool questionnaires. Data collected through all these techniques was triangulated in the form of analytical memoranda which helped to develop analytical statements aligned with the research goals. The findings confirmed the evident practice disconnect between water management and curriculum practices which was found to be problematic at Fort Cox. The findings also suggest that there were inadequate water management topics across the curriculum. The findings lead to recommendations including future research recommendations for possible implementation. One notable recommendation is staff development on current sustainable water management and curriculum practices to address the challenges of both Fort Cox and the region. , Thesis (MEd) -- Faculty of Education, Education, 2021

- Description: The Pericles Citizenship Law of 451 made citizenship contingent on an individual man having Athenian blood on both his father and mother’s side. Men with foreign mothers were denied any rights to the key institutions that conferred Athenian belonging, such as deme and phratry membership, as well as, of course, citizenship. When, however, the Peloponnesian War began in 431, the population of Athenian citizens was quickly diminished by military conflict and plague and they sought a solution to repopulate their numbers with as little change to the original law as possible. The result was an amendment in 429 allowing citizens with no living legitimate (γνήσιοι) heirs to legitimise their bastards (νόθοι) in their place. A year after this, Euripides wrote the Hippolytus, a play that deals very closely with the issues of bastardy, bastards’ place in the polis and the oikos, and their treatment by those who are legitimate. As the war went on, he proceeded to produce two other plays containing bastard characters, the Andromache (c.425) and the Ion (c.413), in which he similarly explored the consequences of illegitimacy. In all three plays his attitude towards bastards is overwhelmingly sympathetic and the way he chooses to present their situations suggests his disagreement with the arrogance and antipathy that continued to push many of these often very worthy individuals to the fringes of society. This thesis seeks to examine Euripides’ presentation of bastards through a close reading of the relevant texts, in order to understand how the plays reacted to the contemporary circumstances of and what comments they are making. , Thesis (MA) -- Faculty of Humanities, School of Languages and Literatures, 2021

- Description: This research paper explores the concept of emotional labour through the lens of the dark side of emotional labour, which includes emotions such as anger, aggression, intimidation, and neutrality. The concept of the dark side of emotional labour seeks to investigate the experiences and effects the performance of these emotions has on police officers as required by the SAPS organisation. These experiences are explored using three central themes: emotional neutrality, emotional toxicity, and emotionally dirty work. This paper places emphasis on emotional labour not only restricted to the performance of positive emotions such as smiling and presentable appearance such as Arlie Hochschild (1983) account of air hostesses but also extending to the expectation or requirement for the performance of dark emotions, which is quite evident in the case of police officers. This study was conducted in KwaZulu Natal, with Police Officers that have acquired the necessary training to be police officers and have worked a minimum of 2 years. The research methodology used was qualitative, and data were obtained from semi-structured interviews. These were then analysed and presented in line with the research objectives. The research found evidence of how individuals' different positions influence how frequently they perform and express negative emotions. It found that the gender difference also contributes to the diverse experiences of dark emotions. Furthermore, it found that the continuous experience of negative emotions has, to an extent, affected the police officers in their lives outside of the organisation. This study concluded by discussing the implications and recommendations for further research. , Thesis (MSocSci) -- Faculty of Humanities, Sociology, 2021

- Description: Salmonella enterica serovar Typhimurium (S. Typhimurium) is a foodborne pathogen infecting humans and animals, contributing to significant morbidity and mortality worldwide each year. The increase in antibiotic-resistant S. Typhimurium infections in recent years has highlighted the need for new antibacterial drugs and drug targets. S. Typhimurium can acquire biotin through de novo biosynthesis or via transport from its extracellular environment. The importance of the vitamin for bacterial survival, coupled with the absence of the biotin biosynthetic pathway in humans, makes the biotin biosynthetic enzymes attractive targets for drug discovery. The study's primary aim was to determine the relative importance of the biotin biosynthesis and transport pathways for the in vitro and ex vivo growth and survival of S. Typhimurium, with the goal of validating the pathways as valid targets for antimicrobial drug development. In order to achieve this aim, we generated S. Typhimurium mutant strains harbouring deletions in either the biotin biosynthetic gene, bioB, or putative high-affinity biotin transporter, yigM (ΔbioB and ΔyigM, respectively), as well as a double mutant in which the two mutations were combined (ΔbioB ΔyigM). Since the simultaneous disruption of biotin biosynthesis and transport in the double mutant may form a synthetic lethal combination, preventing further analysis of the strain, we also constructed a conditional mutant in which the promoter of the yigM gene was replaced by the arabinose-regulatable, PBAD promoter in the ΔbioB background (ΔbioB PBAD::yigM). Since the expression of the YigM in this strain is arabinose-regulatable, its role as a biotin transporter can be evaluated by altering the arabinose concentration in the growth media. Once the mutant strains were isolated and verified genetically, their growth and that of their genetically complemented counterparts were analysed in liquid and/or solid M9 minimal medium in the absence of biotin. Consistent with previous observations, the ΔbioB auxotrophic mutant's growth was severely compromised in minimal media in the absence of biotin. The growth of the strain could, however, be restored by supplementation with exogenous biotin or expression of the wild type bioB gene from an episomal plasmid. The ability of biotin to reverse the growth defect of the ΔbioB mutant strain was, however, dependent on the presence of a functional YigM, since biotin supplementation did not affect the growth of the ΔbioB ΔyigM double mutant strain. The introduction of a second copy of the yigM gene in the ΔbioB ΔyigM background, however, restored the growth of the strain in the presence, but not absence, of biotin. The dependence of the double mutant on both YigM and biotin for growth supports the idea that the protein functions as the sole or primary biotin transporter in S. Typhimurium, as it has recently been shown for E. coli (Ringsletter, 2010; Finkenwirth et al, 2013). The essentiality of YigM for biotin transport was subsequently verified by two independent means. Firstly, the growth of the ΔbioB PBAD::yigM promoter-replacement mutant was strictly dependent on the inclusion of arabinose in biotin-supplemented M9 minimal media supplemented, indicating that the expression of YigM from the PBAD promoter is essential for biotin transport. Secondly, following treatment with a known small-molecule inhibitor of the biotin biosynthesis, MAC-13772, exogenous biotin was capable of restoring the growth defect of the YigM+ wild type S. Typhimurium strain, but not the YigM− ΔyigM mutant. Taken together, these findings confirm that YigM serves as the biotin transporter for S. Typhimurium and that the corresponding ΔyigM mutant is, as a result, defective for biotin transport. Having confirmed the genotypes and phenotypes of the ΔbioB, ΔyigM, and ΔbioB ΔyigM mutants, we next analysed the importance of the biotin biosynthesis and transport pathways for the growth and survival of S. Typhimurium within the intracellular environment. To this end, we determined the proliferation of each of the mutant strains following infection of HeLa epithelial and RAW264.7 macrophage-like cell lines. Our results revealed that the de novo biosynthesis of biotin is required for the optimal growth of S. Typhimurium following infection of both epithelial and macrophage-like cell lines. Disruption of biotin transport, by contrast, had no significant effect on the intracellular proliferation of S. Typhimurium when a functional pathway for the biosynthesis of biotin was present. The simultaneous disruption of biotin biosynthesis and transport, however, resulted in significant attenuation of S. Typhimurium in epithelial cells, while bacterial survival in macrophages decreased to below the limit of detection. Overall, our results suggest the S. Typhimurium relies primarily on biotin produced by the de novo biosynthesis pathway to support its growth in the intracellular environment. While YigM-mediated biotin transport is essential for sustaining the viability of intracellular S. Typhimurium in the absence of de novo biosynthesis, it appears to play a relatively minor role in the acquisition of biotin during growth in the nutrient-limited Salmonella containing vacuole. Our findings suggest that inhibiting biotin biosynthesis may be a viable strategy for combating systemic infections caused by Salmonella, as has been recently proposed for other medically important bacterial pathogens (Carfrae et al., 2020). , Thesis (MSc) -- Faculty of Science, Biochemistry and Microbiology, 2021

- Description: Salmonella enterica serovar Typhimurium (S. Typhimurium) is a foodborne pathogen infecting humans and animals, contributing to significant morbidity and mortality worldwide each year. The increase in antibiotic-resistant S. Typhimurium infections in recent years has highlighted the need for new antibacterial drugs and drug targets. S. Typhimurium can acquire biotin through de novo biosynthesis or via transport from its extracellular environment. The importance of the vitamin for bacterial survival, coupled with the absence of the biotin biosynthetic pathway in humans, makes the biotin biosynthetic enzymes attractive targets for drug discovery. The study's primary aim was to determine the relative importance of the biotin biosynthesis and transport pathways for the in vitro and ex vivo growth and survival of S. Typhimurium, with the goal of validating the pathways as valid targets for antimicrobial drug development. In order to achieve this aim, we generated S. Typhimurium mutant strains harbouring deletions in either the biotin biosynthetic gene, bioB, or putative high-affinity biotin transporter, yigM (ΔbioB and ΔyigM, respectively), as well as a double mutant in which the two mutations were combined (ΔbioB ΔyigM). Since the simultaneous disruption of biotin biosynthesis and transport in the double mutant may form a synthetic lethal combination, preventing further analysis of the strain, we also constructed a conditional mutant in which the promoter of the yigM gene was replaced by the arabinose-regulatable, PBAD promoter in the ΔbioB background (ΔbioB PBAD::yigM). Since the expression of the YigM in this strain is arabinose-regulatable, its role as a biotin transporter can be evaluated by altering the arabinose concentration in the growth media. Once the mutant strains were isolated and verified genetically, their growth and that of their genetically complemented counterparts were analysed in liquid and/or solid M9 minimal medium in the absence of biotin. Consistent with previous observations, the ΔbioB auxotrophic mutant's growth was severely compromised in minimal media in the absence of biotin. The growth of the strain could, however, be restored by supplementation with exogenous biotin or expression of the wild type bioB gene from an episomal plasmid. The ability of biotin to reverse the growth defect of the ΔbioB mutant strain was, however, dependent on the presence of a functional YigM, since biotin supplementation did not affect the growth of the ΔbioB ΔyigM double mutant strain. The introduction of a second copy of the yigM gene in the ΔbioB ΔyigM background, however, restored the growth of the strain in the presence, but not absence, of biotin. The dependence of the double mutant on both YigM and biotin for growth supports the idea that the protein functions as the sole or primary biotin transporter in S. Typhimurium, as it has recently been shown for E. coli (Ringsletter, 2010; Finkenwirth et al, 2013). The essentiality of YigM for biotin transport was subsequently verified by two independent means.

- Description: This research investigates changes in journalistic identity with the introduction of online journalism practices in the SABC newsrooms. The study is a qualitative analysis of in-depth interviews with 6 SABC journalists. It focuses on SABC journalists who embrace a professional identity. Participants were selected from all three of the SABC newsrooms: Television, Radio and Digital News. The research reveals that SABC News journalists are - due to digital production workflows - increasingly pressured to work on their own in the field, with additional responsibilities and fewer resources, while taking on editorial duties and managing corporate and personal social media accounts. As the roles of SABC journalists become digitally disrupted and blur with those of technicians, editors and marketers, I ask how this might in turn disrupt journalistic identity. The interviews reveal how these SABC journalists have always understood their identities and values in opposition to those of corporate SABC leadership. While they, the journalists, sometimes allowed editors to change their stories, this was not done without resistance; it was a strategic compromise, since they understood the greater balance of their work to serve the public. However, this notion of being separate from the corporate identity has been disrupted through digital and social media, as it conflates their identity with the SABC brand. Journalists experience this acutely through ‘trolling’. Yet, conversely, some are also able to retain a sense of an independent professional identity through a direct relationship with the public on social media. Another key finding was that digital media disrupts the centrality of primary journalistic research or ‘legwork’, and instead, journalists increasingly spend time on the selection and repackaging of user-generated content. As some journalists are allocated more deskwork they experience a loss of status among their colleagues. The diminished role of journalists’ primary research, or eye-witness testimony, has created tensions in journalistic identity and what it means to be a ‘real’ journalist. Despite their concerns for the danger of reporting in the field in South Africa, SABC journalists considered such verification work crucial to their identity and what it means to be a journalist. , Thesis (MA) -- Faculty of Humanities, Journalism and Media Studies, 2021

- Description: Marine seagrass, Zostera capensis, is a highly productive flowering marine seagrass found on the eastern and southern coasts of South Africa and provides a variety of ecosystem services, which include reducing the effects of erosion, trapping nutrients, creating a nursery habitat for fish species and reducing sedimentation. Despite their formal protection status, Z. capensis meadows are regressing, often due to anthropogenic influences. Globally, multiple studies have documented the ecological importance of seagrass services, to both humans and nature, but economic evaluations of these services have not been as extensive. Numerous valuation methods have been used in literature and in practice to value non-market environmental resources and ecosystem services, where results vary. The most widely used non-market environmental valuation method is the contingent valuation (CV) method, which allows for the valuation of environmental resources that are not sold in the market through a stated willingness to pay (WTP) amount, contingent upon a particular scenario. However, the CV method is susceptible to various limitations and forms of bias. As a result, alternative environmental valuation techniques have been reviewed in literature. Deliberation has been suggested as an improved valuation approach to overcome the criticisms of the CV technique, as it increases respondents’ understanding and knowledge of the environmental resource under discussion, through the incorporation of debate, discussion, participation and social learning, thereby producing more reliable valuations of non-market environmental resources. The deliberative monetary valuation (DMV) method has been advocated as an important valuation method to achieve more comprehensive and reliable valuations of complex and unfamiliar public goods, such as ecosystem services. This thesis explored the determinants of WTP for the protection of seagrass, and whether deliberation can be used to supplement findings and values obtained from the individually sourced WTP values. As a result, the study used a dual-method approach to obtain both individual and deliberated WTP values from a range of stakeholders with varied socio-demographic characteristics by using both the CV method and a deliberative focus group, for the ecosystem services that seagrass Z. capensis provides to the Knysna community, South Africa. The results showed that age, education, use frequency and mistrust in local government were determinants in WTP, while deliberative elements uncovered that respondents’ knowledge of an environmental resource and a consideration of the valuation scenario were important factors in determining WTP. It was found that 55% of the respondents were willing to pay to conserve the ecosystem services of seagrass in the Knysna estuary through a monitoring programme. Among those that were willing, the mean WTP amount was approximately R132 per month per household. Although the circumstances in which the deliberative focus group discussion were run were not ideal because of the COVID-19 lockdown, the results showed some interesting potential benefits of using deliberation in complex public good valuation studies. , Thesis (MEcon) -- Faculty of Commerce, Economics and Economic History, 2021

Clinical psychologists working with these trauma narratives, within a psychiatric context, are therefore at risk of experiencing vicarious trauma, Post Traumatic Stress-Disorder (PTSD), and secondary traumatic stress. This study aimed to explore the lived experiences of clinical psychologists who treat patients that are either trauma survivors or perpetrators in a psychiatric hospital. Individual semi-structured interviews and follow-up interviews were conducted with three clinical psychologists based at a psychiatric hospital in the Eastern Cape. Data was analysed using Interpretive Phenomenological Analysis. All participants reported experiencing symptoms of vicarious trauma and secondary traumatic stress while treating both victims and perpetrators. The findings also discovered an element of danger, as well as socio-political factors that clinical psychologists experience. Participants also reported experiencing vicarious post-traumatic growth, enhanced by their coping strategies, while providing psychological services to traumatised patients. , Thesis (MA) -- Faculty of Humanities, Psychology, 2021

- Description: In South Africa, choral music has been prominent in schools, churches, and community choirs since the 19th century. However, the majority of South Africans know little of the history of indigenous choral music. This study investigates the origins of South African indigenous choral music, its canonic figures, and their contribution to this genre in promoting an African identity among the indigenous people of South Africa. Using the methodological lens of historical ethnomusicology, this thesis explores the genesis of choral music in South Africa. Choral music was introduced to the region when it was first colonised by the Dutch East India Company in 1652. Missionaries established institutions in the villages of the local people and translated the Bible and hymn books into the local languages. These actions had lasting consequences for music, and choral singing was greatly advanced. In addition, in this work early composers of South African indigenous choral music are recognised in an effort to establish a choral canon. Three definitive choral periods are recognised, namely those of the first-generation, second-generation, and post-colonial composers. Using this historical framework, this thesis investigates the social and political influence these composers had on African identity during the liberation struggles in the late colonial era and during the early apartheid period. The history and compositions of the composers are discussed, including how they used their compositions as political tools and as mouthpieces to communicate societal issues of concern to the indigenous people during and after the colonial era. , Thesis (MMus) -- Faculty of Humanities, Music and Musicology, 2021

- Description:
The aim of this study was to explore the relationship between South Africa’s top seven bank’s business model description and their financial performance. Research has highlighted that there is a relationship between business models and performance, however, a limited amount of studies have provided empirical evidence to this effect. The study followed a deductive approach by firstly assessing and analysing the components of the banks business model according to the IIRC’s International
Framework, and then comparing the components focus of each bank for every year of this study; followed by an assessment, analyses and evaluation of each banks financial performance using the CAMELS Rating System model. Once these analyses were done for both business model description and financial performance, the study attempted to assess if the banks with the richest business model description yielded the best financial performance. The findings revealed that the banks with the richest business model description were not necessarily the best performing banks, in actual fact, these banks had low ratings for their performance, and the banks with the lowest rating for their business model description had the highest financial performance rating. However, other factors contributed to these ratings, such as some banks had low ratings for their business model description due to their business models not following the Framework. Conversely, for a more detailed and an in depth analysis and to distinguish whether there is a relationship between business model description and financial performance, the study applied correlation coefficient by using the business model description scores and financial performance components scores for each bank for the three years. The results revealed that there was a strong positive correlation between 2017 and 2018, and a weak positive correlation in 2019. This meant that indeed there was a relationship between the business model description and the bank’s financial performance. While the limitations of this study have been acknowledged, the study has contributed to the knowledge of understanding the relationship between business models and financial performance in a South African context. However, further research could be conducted on more banks in order to deduct a broader view on the relationship between business model description and financial performance of South African banks. Moreover, it would be of greater significance to conduct the various analyses over a longer period of time, because with a broader scope of data, for a longer period, more conclusive findings could be possible. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2021 - Full Text:

Moreover, it would be of greater significance to conduct the various analyses over a longer period of time, because with a broader scope of data, for a longer period, more conclusive findings could be possible. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2021 - Full Text:
The Relationship between capital adequacy and profitability under Basel III in the Namibian banking sector

- Description: Globally, capital adequacy is one of the most central topics for both regulatory authorities and banks. It promotes stability and intends to reduce bank insolvency. It also represents the most important element of banks’ profitability (Profits are the first line of defense against losses from credit loss in a bank). After the collapse of Bretton Woods in 1973, many banks incurred large foreign currency losses, with Banks outside Germany having taken heavy losses on their unsettled trades with Herstatt Bank in Cologne, West Germany, when it collapsed in June 1974. This study empirically tests the relationship between changes in the capital adequacy ratio under Basel III and return on equity (ROE) of the Namibian banking sector and whether such relationships exist in the short run or long run. The study used panel quarterly data for a sample of three Namibian commercial banks from the year 1999 to 2019.It employed one panel unit root tests namely: Im, Pesaran and Shin W-stat (IPS). To test the existence of a long-run relationship (equilibrium) or effect between the dependent and independent variables, the study employed the Panel Co-integration methods using Pedroni and Kao (Engle-Granger based) tests. The study carried out the Hausman test to determine the best approach for analysis and determined the PMG approach to be the preferable model for analysis. Various diagnostic tests such as multicollinearity through the correlation analysis, autocorrelation, and heteroscedasticity and cross-sectional dependence tests were carried out to determine if the data set is well-modelled and if the results can be taken seriously. The study’s results under the PMG model showed that ROE and CAR have a positive significant relationship in the short run. A dummy variable to capture the connection between ROE and CAR before and after BASEL III shows that the relationship is positive and significant indicating that ROE increases more when there is capital regulation than when there is no capital regulation. The study also concluded that there is no long run relationship between CAR and ROE. Finally, the interaction effect between the dummy variable and CAR is negative but significant and thus indicating that the positive relationship does not persist post Basel III. , Thesis (MCom) -- Faculty of Commerce, Economics and Economic History, 2021

- Description: This thesis explores the functioning of branch politics within the African National Congress (ANC) and the influence of branch politics on the organization and its structures. The ANC has many of the characteristics of a mass party. In mass parties, mass participation is supposed to be promoted through the activities of party branches. This thesis documents the weakening of the ANC’s local level structures and their political control over the organization’s decisions. ANC branches are investigated as democratic vanguards of ANC’s mass party persona, in relation to their functioning as the most basic units of the organization. The thesis reflects on branch members’ experiences in different ANC branches to understand the interplay between branch politics, political power, and patronage politics within the ANC. This research project also explores the possibility of manipulation of ANC branches by senior leaders and would-be-leaders of the ANC. The thesis then concludes by summarising the state of branch politics within the ANC and giving recommendations on further study with regards to branch politics of the ANC. , Thesis (MA) -- Faculty of Humanities, Political and International Studies, 2021

- Description: Throughout the world, urbanisation is at an all-time high. It is estimated that two-thirds of the global population will be living in urban centres by 2030. The highest urban growth rates are currently found in sub -Saharan Africa, however, approximately 70% of urban residents in Sub-Saharan Africa reside in informal settlements. Such processes have resulted in reduced areas of natural space and biodiversity. While the benefits of exposure to and experiences of nature to human well-being and quality of life are increasingly being acknowledged, these links are largely understood through a western lens, where nature and culture are dichotomised. The implications of this are that the types of nature(s) that are made available in urban areas are designed to provide opportunities for urban residents to only engage in recreational and relaxation activities within such places. However, among indigenous and non-westernised communities, culture is a dynamic and holistic entity, deeply rooted in the constructions of nature. Very few studies from the global south have entered this dialogue. In response, this study, conducted amongst Xhosa speaking urban residents living in two medium-sized towns, was undertaken to explore the connections and meanings they attributed to nature(s) and how their engagement in such places contributed to their sense of well-being. This study found that strong connections and meanings to nature still exist. Many of these relate to personal experiences which are given meaning through local understandings and associations which are deeply embedded within cultural practices and rituals. Engagement and or memories of such are strongly associated with a sense of well-being often only experienced in rural areas. In such contexts, well-being is also understood as a holistic concept that is underpinned by these nature-culture connections. Within an urban context, the benefits of such connections are hindered by the types of nature(s) found in these areas as well as high levels of crime and the poor management of such places. , Thesis (MA) -- Faculty of Humanities, Anthropology, 2021

Thrice-born Dionysos: an analysis of the birth narrative of Dionysos in Nonnos of Panopolis’ Dionysiaca

- Description: The following paper aims to analyse lines 660 – 774 of Euripides’ Bacchae paying close attention to the representation of the bacchants in the account given to Pentheus by the herdsman.1 Accompanying the translation is a brief commentary further elaborated and discussed in the paper below. The purpose of this paper is to investigate how the Theban women are portrayed in the hills outside of Thebes and the implications this might for the inherent conception of the supposed structure of the polis and the oikos. Dionysos’ arrival in Thebes hails a systematic disruption of the social order of the Theban polis. His presence causes an inverting of all that is familiar to the Thebans, the unknown becomes known and the known reveals itself as unknown. Euripides’ Bacchae was first performed at the City Dionysia in 405 BCE, in the year after the tragedian’s death. The play dramatises the arrival of the god Dionysos to Thebes to exact vengeance on those responsible for his mother’s death and to establish his mysteries there (line 24f & 47f). Before one can begin any analysis of the text, it is important to establish the context established by the play, as this context is important to a fuller understanding of the text. , Thesis (MA) -- Faculty of Humanities, School of Languages and Literatures, 2021

To fail at becoming South African: Moral blindness, liminality, and Rainbowism

- Description: In an effort to move away from Apartheid and its evils -South Africa and South Africans have committed to a shared moral project -the Rainbow Nation-Building Project (RNP); a project that confers certain moral duties and responsibilities upon its citizens, including a joint commitment to robust inclusivity, equality, and unity. Importantly, however, our environments –be they physical, social, or psychological –are such that they (actively or passively) obscure our awareness of some morally relevant facts about our society, and thereby hinder us as moral agents and therefore threaten our abilities to fulfil our moral project and commitment.What does it mean for us -a society ostensibly committed to the RNP -to be plagued by racism, sexism, queerphobia and xenophobia? What is it that contributes to our complicity regarding social practices and ideas that we would otherwise find morally objectionable? What does it say about our commitment to our publicly-exalted ideals and values (of inclusivity, diversity, reconciliation, justice, and unity) when we are unwittingly complicit in the marginalisation and social exclusion of members of our society? And how can institutions such as universities work to overcome this?In this work, I argue that the obscuring of, and failure to perceive, morally relevant facts that call on us for ethical attention and/or action -a phenomenon I refer to as ‘moral blindness’ -is responsible for at least some of our behaviours and practices that run contrary to our moral ambitions; and therefore has profound implications for us as moral agents and our ability to succeed in our moral goals. Moral blindness, then, is both an epistemic and ethical concern that enables socially unjust systems to perpetuate themselves; and is thus a threat toallmoral projects.I argue that, for South Africa, much of what can be identified as moral blindness is the direct result of the shifting and conflicting socio-cultural conditions the nation finds itself liminally caught amidst in its transition from its Apartheid past and towards its promised inclusive Rainbow Nation future. Commitment to the RNP, I argue, involves a self-transformation and habituation of certain supportive virtues on the part of South Africans to become the kinds of people who are compatible with the Rainbowist society -whom I call Rainbow Citizens. But this self-transformation itself is also a moral project, and therefore subject to the threat that moral blindness presents, and so too can be failed. If all this is true, then it seems that if we do not take moral blindness seriously, we could ultimately fail to become South African. , Thesis (MA) -- Faculty of Humanities, Philosophy, 2021
