- Description: Significant competition challenges confront South Africa's port sector. The sector is also essential to the Eastern Cape Province's economic and social standing. This study was conducted with the objective of helping the port industry in South Africa apply the continuous improvement (CI) philosophy more successfully. The formation of an organisational culture that was conducive to CI was accomplished via the identification of key leadership practices and behaviours. The principal objective of the study was to ascertain, examine, and conduct an empirical examination of the potential impact of diverse leadership practices and behaviours on the culture of the organisation. As a result, the goal of the study was to combine well-researched theories and findings about general organisational culture with more recent findings and firsthand knowledge about CI culture and its significance for the effective execution of CI methodology. Formulating a causal framework for CI culture was the main objective of this work. A literature study was conducted on organisational culture, CI principles, and the port industry. This assessment clearly supported CI as a proven strategy for port industry improvement. One of the main reasons why so many organisations are unable to properly deploy CI is the misalignment of their organisational cultures. Furthermore, there was proof of the crucial part that the conduct and behaviour of leaders might play in the formation of a CI culture. Based on the research study, a framework was created to direct these activities and behaviours. The research methodology used to ultimately create the framework was through an empirical study using a quantitative approach. This quantitative approach was used to evaluate eight hypotheses of this study. Additionally, the validity and reliability of the study was also assessed. The eight major types of leadership actions addressed in this framework, and was tested through the hypotheses, included supportive leadership, process management, employee empowerment, organisational values, reward system, external interaction, customer focus, and future orientation. The association between the eight criteria and the existence of CI culture was then investigated empirically using a structured questionnaire. After this, the data was extensively analysed and statistically scrutinised. The findings showed a substantial positive correlation between the degree of CI culture that was presently in place (dependent variable) and four of the eight categories (independent variables). The four categories were external interaction, process management, organisational values, and supportive leadership. After illustrating these connections, the study's recommendations and conclusions were presented in accordance with the data. The recommendations include improving the framework even more by giving additional information about the precise leadership behaviors connected to each variable and increasing the scope of the study to more than just one sample from one port in South Africa. , Thesis (MEng) -- Faculty of Engineering, the Built Environment, and Technology, School of Engineering, 2024

- Description: This study investigates the complex relationship between education and youth unemployment in South Africa, utilising data from the 2021 General Household Survey. Employing Logit and Probit models, the research analyses the impact of various factors on the likelihood of youth unemployment, such as education level, province, gender, age, race, type of institution, internet access, access to electricity, and household income. The findings of the study reveal that having a diploma, undergraduate degree, honours/postgraduate diploma, M-Tech, or master’s degree decreases the probability of youth unemployment. Factors such as being white, belonging to the age groups 25-29 or 30-34, and higher household income also reduce the likelihood of unemployment. However, residing in certain provinces such as Free State, KwaZulu-Natal, Northwest, or Limpopo increases the probability of youth unemployment. The sensitivity analysis establishes differences between provinces where mining activities are or are not the main industry. Notable variations include the impact of education on unemployment likelihood and demographic factors affecting different regions. In conclusion, this study contributes valuable insights to policymaking efforts aimed at addressing youth unemployment in South Africa. By examining the intricate connection between education and employment, the research advocates for targeted interventions to bridge the education-employment gap and cultivate a more inclusive labour market for the nation's youth. , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2024

- Description: Globally, Small and Medium Enterprises (SMEs) are the driving force that keeps the economy of a country going and although the overall economic contribution of SMEs is impressive worldwide, in South Africa (SA), there is a high rate of failure amongst SMEs. Although the survival rate is low, South African SMEs contribute up to 22% to the Gross Domestic Product (GDP) in the economy. SME funding is a critical component of this growth and access to finance is one of the primary challenges that SMEs face in the country, along with a supportive environment to facilitate SME survival and growth. The formation of what was initially Industrial Development Zones (IDZs), now Special Economic Zones (SEZs), was one instrument introduced by the South African government to bolster the economy through upscaling manufacturing capacity, increase exports and create employment. The first SEZ in SA, Coega, managed by the Coega Development Corporation (CDC), a state-owned enterprise (SoE) based in the Nelson Mandela Bay Municipality (NMBM) with operations throughout SA. A major shortcoming in the development of the SMEs operating in the SEZ, was the inability to access the project finance required to commence construction projects once they were awarded a tender. The CDC established an internal finance subsidiary, Small Business Finance and Support (SBFS), in June 2014. The aim of this study, therefore, is to explore the effectiveness of the project financing offered by SBFS in enabling the execution of SME construction clients’ projects. The interpretivist paradigm, following a qualitative research approach was chosen to evaluate the effectiveness of the SBFS operations and determine how their funding enabled the completion of construction SME projects. Input was obtained from 20 participants involved in CDC construction projects, namely three Project Managers, three Programme Managers, two Mentors and 12 Clients via telephonic, face to face and virtual Microsoft Teams using self-developed semi-structured interview schedules. Data was analysed using thematic analysis. The trustworthiness of the study was ensured in terms of credibility through triangulation, dependability through the creation of an audit trail, transferability through generalisation of individuals with similarities, and conformability through verification. , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Management Sciences, 2024

- Description: This study aimed to generate an in-depth understanding of how the resolutions are being implemented post-mediation process and the labour union, which in this study is the National Union of Metalworkers of South Africa (NUMSA) and the mediator in the process of managing collective disputes between the employer and employee utilising mediation. The study was limited to the Volkswagen South Africa (VWSA) Kariega plant, therefore, the findings are contextually limited to the VWSA Kariega plant. The theoretical frameworks for this study were relative deprivation theory, frustration-aggression theory, Marxism, and dysfunctional and functional social conflict. These were utilised to explore and describe the phenomenon under investigation. This study employed a qualitative method to answer the research questions and address its problem statement. The data were collected through focus group discussions and elite interviews. The study used a purposive sampling technique, and the sample included 33 participants. The primary research question was: Were the agreements mediated at the VWSA Kariega plant effectively implemented between 1994 and 2021? The study’s findings imply that for the effective implementation of mediation resolutions, the following should be considered: implementing resolutions within the given timeframe, parties at mediation adapting and accommodating new technological changes and disasters at the National Bargaining Forum (NBF) level, prioritising the education and training of shop stewards and VWSA management representatives on NBF agreements, including the implementation thereof. Managing pertinent issues concerning NUMSA and the Automobile Manufacturers Employers Organisation (AMEO), interpreting NBF agreements, and ensuring that parties differentiate between the Labour Relations Act No. 66 of 1995 (LRA) and NBF processes. At the policy level, the findings imply that parties need to understand the LRA’s role and the process of resolving conflict utilising the formal processes stipulated in the LRA and why the LRA cannot override the NBF agreement as an informal process of managing conflict. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2024

- Description: The study aimed to investigate the effectiveness of the Auditor-General’s findings in controlling public funds, with specific reference to the Bojanala Platinum District Municipality. The research is comprised of six chapters. The research adopted the qualitative research methodology approach. The study provides academic input into public administration, specifically for improving service delivery performance, control and financial performance management in municipalities. The study could contribute to the establishment of effective methods for monitoring municipalities’ control of public funds. The research also identified several strengths and weaknesses of the BPDM, which are vital for effective and efficient service delivery to the community. It is envisaged that other municipalities in South Africa will learn something from it. Furthermore, this research study envisages promoting the best control of public funds within the BPDM and improving the efficiency and effectiveness of service delivery to ensure communities’ well-being and dignity. Based on the findings primarily from the literature review and empirical survey, various recommendations are presented on how the existing status quo of the BPDM can be changed to enhance the better control of public funds, which can assist in service delivery and are aligned with the Batho Pele principles. If these recommendations are adopted, the BPDM will be able to deal with the developmental obstacles it currently faces more effectively and efficiently. , Thesis (MPA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2023

- Description: The built environment in South Africa encounters the challenge of late payment. The issue of late payment has posed a major challenge to the service delivery efforts of government agencies. The delay in remunerating contractors adversely impacts their cash flow and impedes the expansion of their businesses. The construction industry is capital-demanding, and the timely payment of contractors by clients serves to mitigate cash flow challenges experienced by contractors. The main objective of the study was to gain a deeper understanding of the effects of governments late payments to building contractors in the Eastern Cape. The study therefore examined the experiences of building contractors in the Eastern Cape. The secondary objectives were to identify reasons for late payment and how it affects the cash flow of the contractor; to examine the implications of late payment and the effect it has on business growth; and to determine the reasons behind loss of productivity on site caused by late payment. The study was conducted within a quantitative research paradigm. The epistemological stance of the researcher was objectivist. The population for this study consists of building contractors based in the Eastern Cape Province registered with the Masters Builders Association (EC). A probability sample was used to identify the participants in this research. The data was collected using a survey as the primary research strategy. The survey findings suggest that many issues, including inadequate client finance, prolonged processing time for payment documentation, and non-standard payment methods, all lead to delayed payments to the contractor. The findings of the empirical study showed that, despite the lack of particular laws or regulations governing the construction industry’s payment systems, the sector nonetheless uses a number of common guidelines to guide payment practices. The pay-if-paid approach is associated with several limitations, since the contractor cannot always receive full payments as a result of incomplete or defective projects. , Thesis (MSc) -- Faculty of Engineering, the Built Environment and Technology, School of Built Environment and Civil Engineering, 2024

- Description: Photobiomodulation (PBM) has gained a remarkable interest in the cosmeceutical industry, with research demonstrating supporting evidence for its use as anti-aging and skin-rejuvenating strategies. It is defined as photons at a non-thermal irradiance or non-ionizing photonic energy that trigger photochemical changes within the cellular structure to alter certain biological activities. Lasers were the main focus during the developmental years of light-based treatments, but since the introduction of non-ablative, light-emitting diode (LED) devices, the focus has changed because of the reduced concerns associated with lasers, such as costs, ablation cutting, thermally coagulating tissue, no downtime needed after treatment, and no trained staff needed for operation. The precise biochemical mechanism for PBM is still to be elucidated; however, accepted theories suggest that it has an influence on the activity of cytochrome c oxidase, a complex located in the electron transport chain, or on the viscosity of the interfacial water layer (IWL) of the mitochondrial membrane. The interaction of those cellular components with the light then leads to the primary responses of increased ROS, ATP production, and intracellular calcium, which ultimately leads to the stimulation of secondary responses that are desired for skin rejuvenation and anti-aging, such as cell proliferation and collagen production. There is controversy surrounding photobiomodulation (PBM), mostly because of the incomplete understanding behind its biochemical mechanism and the number of parameters that require optimization; however, it still poses as a promising field for research into anti-aging properties, as seen in the literature. Besides the use of devices for skin rejuvenation and anti-aging strategies, it is not uncommon to see plant extracts and other natural products being used in current skin care products for the same reason? This is mostly because of their promising bioactivities, some of which include antioxidant, anti-inflammatory, anti-bacterial, collagen-stimulating, and cell-proliferating activities. The aim of this study was to investigate the bio-stimulatory capacity of red light on skin cells and to evaluate possible effects it could have in combination with samples that already show promising anti-aging properties in research. The samples that were selected for this study are: Aspalathus linearis (rooibos) unfermented extract, L-ascorbic acid 2-phosphate, mangrove bee honey, stingless bee honey, Sargassum oligocystum (brown seaweed) and Ulva fasciata (green seaweed).It was found that red light irradiation did indeed stimulate the primary responses of ROS, ATP production, and intracellular calcium levels in HaCaT keratinocytes, as proposed in the hypothesised theory. However, none of the proposed secondary responses to cell proliferation or collagen production were demonstrated. In fact, the opposite was observed for cell proliferation and collagen production, where red light irradiation seemed to be cytostatic towards Hs27 fibroblast cells and caused significant decreases in collagen production. Red light energy dosages of 10, 20 and 30 J/cm2, yielded different primary responses with 20 and 30 J/cm2 generally causing more significant stimulation than that of 10 J/cm2. It should also be noted that even if the desired secondary responses were not observed in this study, it does not mean that red light does not have the capacity to still stimulate them. It is clear that the responses are energy dosage-dependent, and it is suggested that lower energy dosages could possibly lead to cell proliferation and that longer incubation periods post-irradiation are required before measuring the endpoint of collagen production. For the combination of red light irradiation and selected test samples, it was demonstrated that the order of samples that yielded the best outcomes is: stingless bee honey > mangrove bee honey > U. fasciata > S. oligocystum > 2-PAA > green rooibos. Unexpected results were demonstrated for green rooibos in the presence and absence of red light, which included decreased ATP production and collagen biosynthesis. Further investigation is therefore needed to have a better understanding of these unanticipated results. , Thesis (MSc) -- Faculty of Science, School of Biomolecular & Chemical Sciences, 2024

The samples that were selected for this study are: Aspalathus linearis (rooibos) unfermented extract, L-ascorbic acid 2-phosphate, mangrove bee honey, stingless bee honey, Sargassum oligocystum (brown seaweed) and Ulva fasciata (green seaweed).It was found that red light irradiation did indeed stimulate the primary responses of ROS, ATP production, and intracellular calcium levels in HaCaT keratinocytes, as proposed in the hypothesised theory. However, none of the proposed secondary responses to cell proliferation or collagen production were demonstrated. In fact, the opposite was observed for cell proliferation and collagen production, where red light irradiation seemed to be cytostatic towards Hs27 fibroblast cells and caused significant decreases in collagen production. Red light energy dosages of 10, 20 and 30 J/cm2, yielded different primary responses with 20 and 30 J/cm2 generally causing more significant stimulation than that of 10 J/cm2. It should also be noted that even if the desired secondary responses were not observed in this study, it does not mean that red light does not have the capacity to still stimulate them. It is clear that the responses are energy dosage-dependent, and it is suggested that lower energy dosages could possibly lead to cell proliferation and that longer incubation periods post-irradiation are required before measuring the endpoint of collagen production. For the combination of red light irradiation and selected test samples, it was demonstrated that the order of samples that yielded the best outcomes is: stingless bee honey > mangrove bee honey > U. fasciata > S. oligocystum > 2-PAA > green rooibos. Unexpected results were demonstrated for green rooibos in the presence and absence of red light, which included decreased ATP production and collagen biosynthesis. Further investigation is therefore needed to have a better understanding of these unanticipated results. , Thesis (MSc) -- Faculty of Science, School of Biomolecular & Chemical Sciences, 2024

- Description: Due to its vast resources, the ocean has been designated the new “economic frontier”. States are focusing on unlocking this potential to boost economic growth, employment and innovation. Because of their substantial resources, corporations are key actors in driving the development of the ocean economy. Although corporations undeniably contribute significantly to realising the ocean economy’s potential, their main activities—including offshore oil and gas exploration and production and fishing—pose great threats to marine ecosystems. This harm to the marine environment may also threaten and adversely impact many people’s lives, health, well-being, livelihood, culture and traditions. In the South African context, this reality is notably seen through Operation Phakisa. This government initiative aims to unlock the economic potential of the ocean economy to expedite the implementation of solutions to poverty, unemployment and inequality. This race to utilise the oceans and its resources brings to the fore the interaction between the right to have the environment protected and socio-economic development anticipated in section 24 of the South African Constitution. The South African Constitution through section 8(2) acknowledges that non-State actors such as corporations can abuse human rights in horizontal relationships. However, unlike the State, non-State actors are only bound in certain circumstances. Therefore, this thesis examines whether and, if so, to what extent section 24 of the Constitution binds juristic persons at sea. This thesis examines the direct application of international norms to non-State actors to determine how international human rights law addresses non-State actors' conduct that impairs an individual’s guaranteed rights. It was determined that international human rights law has an indirect horizontal effect. This means that in cases where a non-State actor impairs an individual’s human rights, international law permits the victim to hold the State responsible for the violation rather than the non-State actor who was the perpetrator. For a non-State actor to incur direct obligations to uphold certain human rights, the State must create these obligations in its domestic law. The thesis explored how the South African Bill of Rights imposes direct human rights obligations on non-State actors in a horizontal dispute. It was found that whether an entrenched right binds a non-State actor depends on a multi-factor enquiry confirmed by the Constitutional Court. Based on that enquiry, it concluded that the environmental right is capable of and suitable for horizontal application. Furthermore, non-State actors can bear positive and negative constitutional human rights obligations arising from the environmental right. A failure to comply with these obligations would violate this constitutional right. The most significant findings of this thesis pertain to the applicability of South Africa’s human rights law framework at sea. This is because the legal regime applicable at sea differs from that on land. The United Nations Convention on the Law of the Sea assigns jurisdiction to States in the different maritime zones for different purposes. To elucidate South Africa's rights and obligations as delineated in the LOSC, the thesis focused on two examples: the exploitation of marine living resources and the prospection, exploration, and exploitation of marine non-living resources. Subsequently, the extent to which South Africa has taken measures in its domestic law to implement those rights and duties was assessed. In addition, this approach was appropriate because questions concerning the horizontal application of the South African Bill of Rights necessitate contextual analysis and cannot be answered a priori and in the abstract. Using the multi-factor enquiry, the study showed that, in principle, section 24 of the Constitution might bind juristic persons within South Africa’s territorial jurisdiction, exclusive economic zone jurisdiction, continental shelf jurisdiction and under South Africa’s personal jurisdiction. Furthermore, juristic persons who control vessels registered in South Africa or control a vessel entitled to be registered in South Africa but has departed to a place outside South Africa without being registered might also be constitutionally bound based on flag State jurisdiction. The sole means of preventing South Africa from exercising its authority this way requires severing the jurisdictional connection between South Africa and the juristic person. It was recommended that in ocean-related matters, the connecting factor between South Africa and the juristic person must be considered as an additional factor in the enquiry to determine whether a particular right binds that juristic person. Additionally, since the scope of corresponding rights-holders are “everyone”, even people outside South Africa present in places where the juristic person who is the corresponding duty- bearer operates or where their conduct is felt can hold these actors accountable for their constitutional human rights obligations. , Thesis (LLD) -- Faculty of Law, 2024

These host compounds were readily synthesized by means of Grignard addition reactions on dimethyl terephthalate, employing the aryl halides bromobenzene for H1 (73% yield), p-bromotoluene for H2 (69%) and p-bromofluorobenzene for H3 (70%). Molecular modelling calculations demonstrated that the various C-C-C angles differed between the computed low energy host conformers and those in the host molecules from their PYR-containing crystal structures. However, specified ‘torsion’ angles were in close agreement. Compound 1,4-phenylene-bis(diphenylmethanol) (H1) possessed the ability to form 1:2 host-guest (H:G) complexes with each of pyridine (PYR) and 2-, 3- and 4-methylpyridine (2MP, 3MP and 4MP). Furthermore, H1 showed preferential behaviour towards PYR and 4MP when presented with various mixtures of these four pyridines. Due to the high selectivity coefficients calculated in many instances (the selectivity coefficient, K, is a measure of the selectivity of a host compound for one particular guest in a mixture), it was demonstrated that H1 would be suitable for separations/purifications for many of the mixtures investigated in this work through host-guest chemistry strategies. (These pyridines are difficult to separate by means of the more conventional fractional distillations because of very similar boiling points.) Single crystal X-ray diffraction (SCXRD) analyses revealed that 4MP and 3MP experienced hydrogen bonds with the host molecule which were similar in distance, while the hydrogen bond distance between H1 and 4MP was shorter than that between H1 and 2MP. Furthermore, the hydrogen bond angles in complexes with the preferred PYR and 4MP guest species were more linear than in those having 2MP and 3MP. Additionally, preferred PYR and 4MP experienced significant π‧‧‧π contacts with nearby guest molecules, while disfavoured 2MP and 3MP did not interact in this fashion.

- Description: This study employs a robust quantitative research design meticulously tailored to investigate the nuanced impact of Basel III capital and liquidity requirements on the profitability of South African banks. The data collection process is anchored in a rigorous approach, driven by the acquisition and meticulous review of financial statements sourced from a carefully curated sample of South Africa’s banks. Ensuring the sample’s representativeness is of paramount importance for bolstering the study’s findings. To this end, a purposive sampling technique, distinguished for its deliberate selection methodology, was applied judiciously. This method yielded the selection of 10 banks, chosen carefully to encapsulate a cross-section of the South African banking landscape, so enhancing the research’s validity and robustness. The analysis of this intricate dataset is underpinned by advanced statistical techniques, with regression analysis the principal analytical tool. Specifically, the study harnesses the Arellano-Bond generalised method of moments (GMM), a sophisticated yet versatile statistical methodology appropriate for disentangling complex relationships in longitudinal data. This analytical approach is perfectly suited to trace the nuanced interactions between Basel III’s capital and liquidity requirements and the profitability trajectories of South African banks. Spanning a 12- year timeframe, 2010 to 2022, this study attempts to encapsulate the evolution of the banking landscape in the wake of Basel III’s implementation. This extensive temporal scope enables the research to capture both short-term fluctuations and long-term trends, enriching its insights and lending depth to the analysis. The first objective of this study was to unravel the intricate web of macro-specific and bank-specific factors influencing the profitability of banks in South Africa. Net interest margin (NIM), a pivotal metric reflecting bank profitability and efficiency, was central to the investigation. Empirical insights gleaned from the analysis revealed several key determinants of NIM for South African banks. Notably, NIM displayed a high degree of persistence over time. This suggests that South African banks do not adjust swiftly to changes in market conditions, emphasising the importance for bank managers of considering the long-term repercussions of their decisions on interest, income and expenses. The results also illuminated a set of critical variables closely linked to NIM. These include credit loss, non-interest income, market concentration, stability (Z-score) and inflation. These variables collectively underscored the banks’ ability to navigate the multi-faceted landscape of risks and uncertainties in the banking sector, including credit risk, operational risk, market risk and inflationrisk. The positive relationship between these variables and NIM indicated the banks’ adeptness at passing on costs and risks to customers through higher interest rates or fees, all while leveraging their market power and diversification strategies. Conversely, a negative and significant association emerged between NIM and bank size, GDP per capita, private credit and the repo rate. These variables underscored the competitive pressure and macroeconomic dynamics influencing the demand for and supply of credit in the banking sector. In this context, the negative relationship suggested that larger banks, those operating in more developed and competitive markets, and those encountering lower policy rates, tend to exhibit lower NIM. These banks, due to heightened competition and lower demand for credit, face diminished interest income and narrower margins. Notably, variables like cost-to-income ratio, funding structure and loan-to-deposit ratio did not emerge as significant in explaining NIM for South African banks. This implies that these variables exert a relatively weaker influence on the profitability and efficiency of South African banks, or that their effects are subsumed by other variables in the model. The second objective examined the effect of higher capital buffers on bank profitability. Empirical findings revealed a negative yet statistically insignificant co-efficient for the CET1 variable in the regression analysis. This observation indicated that there is no substantial relationship between Basel III Tier 1 capital ratio (CET1) and bank profitability, as measured by NIM, among South African banks. This suggests that Basel III capital requirements do not have a significant influence on the profitability and efficiency of these banks, or their effect varies depending on other bank-specific or macroeconomic variables. The third objective focused on the effect of Basel III liquidity regulations, epitomised by the liquidity coverage ratio (LCR), on bank profitability in South Africa. Empirical results revealed a negative but statistically insignificant relationship between LCR and NIM. This observation indicates that Basel III liquidity regulations exert no discernible effect on the net interest income of South African banks. This finding could be attributed to the fact that South African banks had already fortified their liquidity positions prior to Basel III implementation, adhering to stringent regulatory requirements and prudent liquidity management practices. As a result, the introduction of LCR did not pose a significant alteration or constraint on the liquidity standing and profitability of South African banks. It also implies that other factors, like market conditions, funding structures or asset compositions, play more pivotal roles than the LCR in shaping the profitability of South African banks. These factors may influence the net interest spread, cost of funds or risk-adjusted returns of these banks. , Thesis (PhD) -- Faculty of Economics and Management Sciences, School of Economics, 2024

The results also illuminated a set of critical variables closely linked to NIM. These include credit loss, non-interest income, market concentration, stability (Z-score) and inflation. These variables collectively underscored the banks’ ability to navigate the multi-faceted landscape of risks and uncertainties in the banking sector, including credit risk, operational risk, market risk and inflationrisk. The positive relationship between these variables and NIM indicated the banks’ adeptness at passing on costs and risks to customers through higher interest rates or fees, all while leveraging their market power and diversification strategies. Conversely, a negative and significant association emerged between NIM and bank size, GDP per capita, private credit and the repo rate. These variables underscored the competitive pressure and macroeconomic dynamics influencing the demand for and supply of credit in the banking sector. In this context, the negative relationship suggested that larger banks, those operating in more developed and competitive markets, and those encountering lower policy rates, tend to exhibit lower NIM. These banks, due to heightened competition and lower demand for credit, face diminished interest income and narrower margins. Notably, variables like cost-to-income ratio, funding structure and loan-to-deposit ratio did not emerge as significant in explaining NIM for South African banks. This implies that these variables exert a relatively weaker influence on the profitability and efficiency of South African banks, or that their effects are subsumed by other variables in the model. The second objective examined the effect of higher capital buffers on bank profitability. Empirical findings revealed a negative yet statistically insignificant co-efficient for the CET1 variable in the regression analysis. This observation indicated that there is no substantial relationship between Basel III Tier 1 capital ratio (CET1) and bank profitability, as measured by NIM, among South African banks. This suggests that Basel III capital requirements do not have a significant influence on the profitability and efficiency of these banks, or their effect varies depending on other bank-specific or macroeconomic variables. The third objective focused on the effect of Basel III liquidity regulations, epitomised by the liquidity coverage ratio (LCR), on bank profitability in South Africa. Empirical results revealed a negative but statistically insignificant relationship between LCR and NIM. This observation indicates that Basel III liquidity regulations exert no discernible effect on the net interest income of South African banks. This finding could be attributed to the fact that South African banks had already fortified their liquidity positions prior to Basel III implementation, adhering to stringent regulatory requirements and prudent liquidity management practices. As a result, the introduction of LCR did not pose a significant alteration or constraint on the liquidity standing and profitability of South African banks. It also implies that other factors, like market conditions, funding structures or asset compositions, play more pivotal roles than the LCR in shaping the profitability of South African banks. These factors may influence the net interest spread, cost of funds or risk-adjusted returns of these banks. , Thesis (PhD) -- Faculty of Economics and Management Sciences, School of Economics, 2024

- Description: This study employs a robust quantitative research design meticulously tailored to investigate the nuanced impact of Basel III capital and liquidity requirements on the profitability of South African banks. The data collection process is anchored in a rigorous approach, driven by the acquisition and meticulous review of financial statements sourced from a carefully curated sample of South Africa’s banks. Ensuring the sample’s representativeness is of paramount importance for bolstering the study’s findings. To this end, a purposive sampling technique, distinguished for its deliberate selection methodology, was applied judiciously. This method yielded the selection of 10 banks, chosen carefully to encapsulate a cross-section of the South African banking landscape, thus enhancing the research’s validity and robustness. The analysis of this intricate dataset is underpinned by advanced statistical techniques, with regression analysis as the principal analytical tool. Specifically, the study harnesses the Arellano-Bond generalized method of moments (GMM), a sophisticated yet versatile statistical methodology appropriate for disentangling complex relationships in longitudinal data. This analytical approach is perfectly suited to trace the nuanced interactions between Basel III’s capital and liquidity requirements and the profitability trajectories of South African banks. Spanning a 12-year timeframe, 2010 to 2022, this study attempts to encapsulate the evolution of the banking landscape in the wake of Basel III’s implementation. This extensive temporal scope enables the research to capture both short-term fluctuations and long-term trends, enriching its insights and lending depth to the analysis. The first objective of this study was to unravel the intricate web of macro-specific and bank-specific factors influencing the profitability of banks in South Africa. Net interest margin (NIM), a pivotal metric reflecting bank profitability and efficiency, was central to the investigation. Empirical insights gleaned from the analysis revealed several key determinants of NIM for South African banks. Notably, NIM displayed a high degree of persistence over time.

- Description: Small, Medium and Micro Enterprises (SMMES), generally abbreviated as SMEs, are enterprises that have revenues, assets or number of employees that are below a certain level. Each country applies an industry-specific criteria when determining enterprises that meet the definition of an SME (Ward, 2020). According to Faye and Goldblum (2022), SMEs are essential employers, and they are vital in job creation. In creating jobs, SMEs thus, contribute to alleviation of poverty and this leads to an improvement in the standards of living of a country’s inhabitants. Through improved employment levels from job creation contributed by SMEs, a country’s economy also grows. The COVID-19 pandemic has resulted to extensive job losses in developing countries because many SMEs contracted their workforce during the pandemic (Faye & Goldblum, 2022). Many non-essential service businesses were prohibited from operating during the pandemic. Governments around the world introduced strict measures to contain the impact of the coronavirus and these included restrictions on travel, business operations and face-to-face interactions (Organisation for Economic Co-operation and Development, 2020). The president of South Africa announced that people needed work permits that would allow them to go to work if they were essential workers, or provided essential services if they were self-employed (Pretorius, 2020). This is how strict the restrictions were, thereby completely blocking non-essential service SMEs from operating. Hence, the objective of the study was to determine the impact of COVID-19 on the Pay TV installation sector in Johannesburg and inferences were made for SMEs in general, with regards to how they were impacted by the COVID-19 pandemic. Based on the research primary and secondary objectives, literature review was conducted, identifying the contribution of SMEs on a country’s social status and economic growth. Other aspects that were reviewed in existing literature included but not limited to factors that contribute to the success and failure of SMEs, challenges faced by SMEs in South Africa, SMEs resilience at times of crises and impact of COVID-19 on SMEs. The study followed a qualitative research approach, and six open-ended questions were asked during the interviews with participants. The aim was to allow participants to express themselves genuinely and authentically to gain a better insight of the impact of COVID-19 on SMEs. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2024

- Description: Since the start of the Yemeni conflict in 2014, both the Saudi-led military and the Iranian-backed Houthi Rebel group have launched missile airstrikes across the nation (Sharp & Brudnick, 2015). These attacks are carried out using high-tech military tools, such as drones, aircraft, bombs, and other weapons. According to Hokayem (2016), nearly 24 million Yemenis require aid as Yemen experiences the world’s largest humanitarian crises. Open Secretes released a report in 2020 outlining that weapons used in the war in Yemen could be traced back to Denel, alluding to its role and complicity in the conflict. The aim of this study is to investigate the role of Denel in the conflict in Yemen and its socio-economic effects. In doing so, South Africa’s trade relations with the Saudi-Arabia will be explored. In addition, unpacking the socio-economic conditions that exists domestically and internationally that influence global arms trade. A qualitative research approach is employed. Secondary research analysis is conducted using government publications, international policy reports, books, journals, and newspaper articles. In addressing the social aspect of the arms trade effects, the humanitarian component uses a psycho-social theoretical framework which encompasses Burtons’ human needs theory. In addition to this main theory, the frustration-aggression theory as well as the relative deprivation theory were applied to support the theory central to the study. Fundamental to this study is understanding Denel’s’ complicity in the conflict in Yemen and the effects thereof. This stems from the company’s trade agreements between itself and Saudi Arabia, which has been at the forefront of multiple proxy wars within the region. Denel’s implied complicity stems from the correlation between the heightened period of conflict in the Yemen and the parastatal’s record-breaking order book during the same period. The research study focuses on the period between 2013 – 2016. Further research has been conducted in order to provide a comprehensive historical account and context of the conflict and the role of Denel as a parastatal organisation. Furthermore, this study delves into ongoing crises and the volatile nature of global arms trade regulations. It is for the reasons alluded to above that the study insists on not limiting period of the study to 2013 – 2016. The study findings suggest that although weapons used in the conflict in Yemen could be traced back to Denel, these were insignificant to the overall contribution to the conflict in Yemen, despite South Africa’s and Saudi Arabia’s breach of the End-User agreement. As a result of Saudi Arabia’s continued infringement of human rights, the state was not to be sold weapons as they are proven to have further ramifications against the protection of human rights. Moreover, the arms trade industry partially functions independently from government intervention and regulation, making it increasingly difficult to implement international policy. What is of paramount importance is the direct effect of conflict on innocent civilians who continue to suffer and the human cost of profit and the struggle for power and resources. Recommendations highlighted in the treatise include striking a balance between profitability and the humanitarian perspective by taking into consideration both private sector profit motives and the public sector's responsibility to prioritise human rights and the well-being of people. This approach ensures efficient management of Denel and reduces the possibility of privatization, as Denel remains the lifeline of the South African Defense Force (SADF). To ensure compliance with domestic and international arms treaty regulations, it is necessary to enforce a stricter process for arms sales justification. The agreement should incorporate legal measures that enable the prosecution of the state in cases where irregularities in weapons sales approval, including corruption or personal/political motives, are identified. The study recommends that Denel should initiate a strategic restructuring plan to revitalise its business model and leadership development. This restructuring should prioritise ethical business practices, legality, and vetting of customer information while ensuring profitability for self-sustainability. Addressing irregular sale agreements is crucial before investing in technology advancement and research. Growth assessment should be based on profit margins and order book prospects to ensure business optimisation and resource adequacy. Denel's success is vital for South Africa's GDP growth. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2024

- Description: Problems have existed in South African SOEs for more than 80 years and in the more recent past, billions of rands in bailouts have begun to accumulate in an effort to revive struggling SOEs and consequently has placed the South African economy under immense fiscal strain. With the use of case study analysis, this study set out to determine the impact bailouts of underperforming SOEs are having on the budget deficit as well as government debt, with particular focus aimed at the contributions of Eskom and SAA. Thereafter, the study adopted a VAR framework and investigated if either the budget deficit or government debt share a relationship with economic growth based on data from 2000-2020. It was discovered that an alarming R331,206 billion has been given out in bailouts to underperforming SOEs over the past decade. As a result, SOEs have been identified by credit rating agencies, financial institutions such as the IMF and the National Treasury as posing one of the greatest threats to the fiscal outlook and a widening budget deficit. Results from the granger casualty tests only found evidence of unidirectional causality running from GDP to both the budget deficit and government debt, meaning there was no evidence to suggest that changes in the budget deficit and government debt influence GDP. The estimated VAR model also failed to find evidence of a statistically significant relationship existing between the budget deficit and GDP as well as government debt and GDP. These findings suggest that there is inconclusive evidence to suggest that underperforming SOEs do impact economic growth via the budget deficit and government debt. However, government expenditure was found to have a statistically significant and negative relationship with GDP which indicates that expenditure has been wasteful and is a reflection of the impact bailouts have on economic growth when considering the significant amount of expenditure directed towards SOEs over the past two decades. , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2024

- Description: The growth of online banking, also known as e-banking, electronic banking or Internet banking, has enticed customers to perform online banking transactions. Even traditional banking institutions are encouraging their customers to adopt online banking services to offer them faster and more dependable services. Online banking services available to customers range from the ability to access their accounts, transfer money between accounts or beneficiaries to more advanced financial services such as applying for loans or making investments. Despite the benefits online banking, it does expose the user to significant risks, including financial fraud and unauthorised payments. The growth of online banking has led to an increase in opportunities for sophisticated fraudsters to commit online banking fraud by means of constantly changing methods that exploit the weaknesses in existing preventive measures, mainly targeting the financial sector and its customers. Due to negligence, curiosity or naivety, online banking fraud victims are often responsible for their own victimisation. Although there is the general perception that customers are not liable for damages incurred due to online financial fraud and that banks will refund the financial losses, the banking industry is moving towards customer co-liability to curb online banking fraud. It has been recognised that financial literacy positively influences a person’s financial behaviour, including online banking. Improving access to financial services through technology requires a higher level of financial literacy to use such services effectively and be less vulnerable to, for example, misleading advertising, fraud, hacking attacks and unauthorised use of data. Given the importance of online banking in the South African economy, as well as the increasing emphasis being placed on online banking customers to education themselves about the safe use of online banking services, the primary research objective of this study was therefore to determine the influence of financial literacy on customers’ ability to detect online banking fraud. In the literature review, the following factors have been identified that could influence online banking customers’ Ability to detect online banking fraud (dependent variable), namely: Financial knowledge, Financial behaviour, Financial attitude, Trust, Attentiveness, Awareness, Risk-perception (independent variables).The empirical investigation adopted a positivistic research paradigm, together with a deductive and quantitative methodology. The methodological strategy used to collect primary data was an online survey, that was cross-sectional in nature. The 280 completed questionnaires were subjected to statistical analyses. The validity and reliability of the measuring instrument was assessed by using a confirmatory factor analysis (CFA) and Cronbach’s alpha coefficients, respectively. Descriptive statistics were also calculated to summarise the data, while inferential statistics included Pearson’s product moment correlations, analysis of variance (ANOVA) tests and multiple regression analysis (MRA) to test the relationships amongst the dependent and independent variables. As a result of the CFA analysis conceptual framework and the hypothesised model were modified. It was hypothesised that Financial knowledge, Financial behaviour, Financial attitude, Trust, Attentiveness, and Awareness are the financial literacy factors that have a significant positive influence on online banking customers’ Risk-perception and ability to detect online banking fraud. The empirical results of this study establish the following predictors or determinants of online banking customers’ Risk-perception and ability to detect online banking fraud, namely: Trust, Awareness and Attentiveness. In doing so, this research contributes to validating the notion that certain financial literacy factors could be important to take into consideration in order to assist online banking customers to be less vulnerable by being able to assess the risk and fraud associated with using online banking services. This study theoretically contributes to the body of knowledge on financial literacy and online banking and online banking fraud in general and the influence of financial literacy factors on online banking customers’ ability to detect online banking fraud in particular in a South African context. This study will enable banks and their online banking customers to gain a better understanding of the impact of financial literacy on customers' levels of risk-perception concerning online banking fraud. This understanding could subsequently improve their awareness, attentiveness and ability to detect online banking fraud and, consequently, reduce the risk of online banking victimisation. , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Management Sciences, 2024

- Description: The growth of online banking, also known as e-banking, electronic banking or Internet banking, has enticed customers to perform online banking transactions. Even traditional banking institutions are encouraging their customers to adopt online banking services to offer them faster and more dependable services. Online banking services available to customers range from the ability to access their accounts, transfer money between accounts or beneficiaries to more advanced financial services such as applying for loans or making investments. Despite the benefits online banking, it does expose the user to significant risks, including financial fraud and unauthorised payments. The growth of online banking has led to an increase in opportunities for sophisticated fraudsters to commit online banking fraud by means of constantly changing methods that exploit the weaknesses in existing preventive measures, mainly targeting the financial sector and its customers. Due to negligence, curiosity or naivety, online banking fraud victims are often responsible for their own victimisation. Although there is the general perception that customers are not liable for damages incurred due to online financial fraud and that banks will refund the financial losses, the banking industry is moving towards customer co-liability to curb online banking fraud. It has been recognised that financial literacy positively influences a person’s financial behaviour, including online banking. Improving access to financial services through technology requires a higher level of financial literacy to use such services effectively and be less vulnerable to, for example, misleading advertising, fraud, hacking attacks and unauthorised use of data. Given the importance of online banking in the South African economy, as well as the increasing emphasis being placed on online banking customers to education themselves about the safe use of online banking services, the primary research objective of this study was therefore to determine the influence of financial literacy on customers’ ability to detect online banking fraud.

- Description: Third-party quality audits (TPQA) facilitate performance improvement and reliability that give confidence to organisations concerning the process quality of services and products. In South Africa, ISO 9001: 2015 standard certification gained popularity as a requirement in the business tender criteria. While TPQA are crucial for evaluating conformance to industry standards, reportedly numerous organisations share disappointments as their expectations seem no longer realised. Certification faces criticism about its effectiveness in delivering TPQA that add value. Research has shown in some cases that despite the revisions of the ISO 19011: 2011 standard and limited studies conducted TPQA are regarded as added cost activities, and their initial purpose as an impartial tool to ensure quality of deliverables is no longer upheld. Increasingly, because of inconsistencies and unethical practices often observed in the industry, organisations question the significance of TPQA. Hence, the need was identified to determine and explain the influence of the ISO 19011: 2018 standard interpretation on the application of the audit guidelines in performing TPQA, to promote consistency in the audit process. A sequential exploratory mixed-method study was conducted employing a document analysis of the ISO 19011: 2018 standard, semi-structured interviews with the certification managers (CBs) and third-party quality auditors; and a survey questionnaire which was sent to quality practitioners and experts. The findings of the qualitative phases of the study were verified during the quantitative phase. The outcome of each phase of the study informed the development of the data collection instrument in the next phase. Two frameworks were designed: A conceptual framework after the document analysis and an empirical framework based on the interview data. The qualitative findings and quantitative results were integrated before conclusions were drawn and recommendations made. Achieving effective audits requires that an audit programme be established, implemented, monitored, reviewed and improved within the confines of the principles of auditing. The study found that the value of the audit process is limited by the different interpretations of the audit guidelines held by CBs and auditors. Adherence to the principles of auditing particularly, integrity and independence were found as the core of the audit process while their disregard reflected failure of the real intent of auditing. In managing the audit programme the study revealed that the inconsistencies in the audit procedures and documents developed for the auditors were ascribed to some CBs’ personal interpretations. Potential pitfalls are exacerbated by most auditors being contracted across the different bodies, and work according to the different CBs’ processes. The different interpretations of the standard suggest that certain guidelines might be vaguely written, resulting in uncertainties concerning reproducibility of the audit process. Competence featured most so that lack of it was perceived as the main hindrance to the audit process. The study recommends formal consultations among experts and practitioners to reflect on the interpretation of the guidelines to manage the audit programmes, and eliminate root causes and practices affecting the audit process. Also recommended is integration of the study findings into auditor training courses to support standardisation and reduce the variations across and amongst the different CBs and auditors. , Thesis (PhD) -- Faculty of Engineering, the Built Environment, and Technology, School of Engineering, 2024

- Description: The unanimous judgment in the CC case of Union for Police Security and Corrections Organisations v South African Custodial Management (Pty) Ltd and Others [2021] ZACC 26, delivered by Judge Khampepe, highlighted the distinct approach to costs in labour matters. While the general rule in litigation is that costs follow the result, the Constitutional Court has consistently emphasised that this principle does not apply in labour disputes, as clarified in the landmark case of Zungu v Premier of the Province of KwaZulu-Natal and Others (CCT136/17) [2018] ZACC 1; (2018) 39 ILJ 523 (CC); [2018] 4 BLLR 323 (CC); 2018 (6) BCLR 686 (CC) (22 January 2018). The court emphasised its constitutional and statutory obligation to depart from the general rule in labour matters. However, section 162 of the LRA provides the LC with the authority to order the payment of costs based on the requirements of the law and fairness. Similarly, section 179 of the LRA grants the LAC the discretion to make cost orders considering the law and fairness. This presents an intriguing legal debate surrounding the interpretation of the LRA provisions and the assertion that costs do not follow the result in labour matters. It raises questions about whether this assertion aligns with sections 162 and 179 of the LRA and whether it applies to labour matters beyond the purview of the LC and LAC, such as disputes rooted in the law of contracts, administrative law or common law which can be adjudicated in alternative forums. This treatise aims to explore the historical development of the South African law of costs, with a particular focus on costs in labour matters. It will critically analyse whether the courts’ approach to costs in labour matters is legally sound, fair and consistent. By delving into these issues, this treatise intends to contribute to the scholarly discussion on costs in labour disputes, assess the appropriateness of the current approach, and propose potential areas for improvement. , Thesis (LLM) -- Faculty of Law, Department of Mercantile Law, 2024

- Description: This dissertation puts forward empirical research conducted about the linkages between film and tourism. The aim of the study is to explore the potential opportunities for tourism as a result of the utilisation of the tourism destination for film purposes. The destination is called Nelson Mandela Bay which is situated in the Eastern Cape of South Africa and comprises of Gqeberha, Kariega and Despatch. It is pertinent to note that in South Africa, the cities of Johannesburg, Cape Town, and Durban are successfully utilising film to promote tourism, however research conducted for government purposes indicates that Nelson Mandela Bay has not utilised this opportunity optimally. In this research a potential strategy for film and tourism in Nelson Mandela Bay is explored through evaluating best practices in Johannesburg, Cape Town, and Durban. This is against the background of international best practices which guide the tourism organisations involved with film in these cities. The research followed a qualitative research approach that utilised interviews and a subsequent focus group discussion to collect data. The findings clearly indicate that film and tourism linkages are present in NMB but that a strategy should be developed for consideration that would guide NMB in terms of capitalising on the relationship between film and tourism. , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2024

- Description: This research is dedicated to the development of a continuous flow process for the production and utilization of monosilane gas. The utilization of continuous flow techniques was instrumental in addressing the challenges and conditions associated with the handling of monosilane gas. Furthermore, the integration of Process Analytical Technologies (PAT) facilitated in-process monitoring and analysis. Chapter one of this research provides an extensive background and literature review encompassing the purification methods of silicon, the latest advancements in the direct synthesis of alkoxysilanes, current synthesis methods for monosilane, the various applications of monosilane, as well as the utilization of continuous flow technology and process analytical technologies. In chapter two, a detailed account of the experimental procedures employed in this research is presented. Chapter three delves into the results derived from each section of the research. The first section discusses an attempt to upscale the continuous flow synthesis of triethoxysilane, based on previous group research. Process Analytical Technologies (PAT), specifically thermocouples, were utilized in this endeavor. The study revealed temperature inconsistencies along the packed bed reactor, which had a notable impact on the reaction capabilities. The subsequent section explores the continuous flow synthesis of monosilane from triethoxysilane. A Design of Experiment (DoE) approach was employed to identify the optimal reaction conditions and compare the effectiveness of two catalysts. The study determined that Amberlyst-A26 emerged as the superior catalyst, offering stability and reasonable conversions over a 24-hour period. In a residence time of 6 minutes and at a temperature of 55 °C, the maximum triethoxysilane conversion of 100% was achieved. PAT, particularly inline FT-IR, was instrumental in monitoring catalyst activity, while continuous flow gas separation techniques facilitated the separation of monosilane. The research also demonstrated further applications of continuous flow techniques in the synthesis of monosilane from tetraethoxysilane and magnesium silicide.
