- Description: As a Zimbabwean artist and educator, living and working in South Africa, my daily experience is that of an “in-between” diasporic subjectivity, which is compounded by the discourses around the uneasy reintegration of post-apartheid South Africa into Africa. This context gives rise to the core philosophical aim of this thesis, which is to explore the notion of “diasporic subjectivities” as a philosophical approach to understanding what it means to be in a complex contemporary reality. The notion of diasporic subjectivities works in the same way as that of “queer subjectivities”, which has been used to understand not just gay people but all people. “Diaspora” names people who have moved, migrated, or been scattered away from an established or ancestral homeland, but retain some sense of belonging to this homeland. From an African perspective, I problematise the concept of an established homeland and the settled subjectivities that belong to it, in contrast to which only the diaspora remains in an uncomfortable state of in-betweenness. Instead, I explore a contention among both European and African existentialist philosophers that the condition of not being at home is the fundamental human condition out of which a home must be created. This would mean that the groundlessness, liminality or in-betweenness of being is experienced not just by the diaspora but by all humans. However, importantly, I find that sociocultural differences due to the history of colonialism gives rise to different experiences of homelessness and the groundlessness of being. This makes a distinction necessary, but to avoid the pitfalls of tying this distinction to geographical locations such as Western versus Non-Western or Global North and Global South, I will refer instead to spaces, practices and even individuals, in which there are “mindsets of entitlement” versus “mindsets of disentitlement”. The former refers to the mindset of ownership characteristic of the settled and developed. The latter refers to the mindset of many who feel a sense of unbelonging, due to disenfranchisement and forced disembodiment and dislocation. I have aimed to support the thesis that the groundlessness, liminality or in-betweenness of being is experienced not just by the diaspora but by all humans, in two ways. Firstly, I consider in detail through various means (narratives, personal reflection, investigation of philosophical texts, dialogues), the philosophical concepts of “belonging”, “home” and “nostalgia” as component aspects of an ontology of diasporic subjectivity. In the second part of this study, I engage in an interpretative process, as outlined by Hans-Georg Gadamer, whereby I use this ontology to help me dialogue with artworks produced by three Zimbabwean artists, Ronald Muchatuta, Gerald Machona, and myself (Vulindlela Nyoni), who share the diasporic condition of being Zimbabweans living in-between Zimbabwe and South Africa. The ontology of diasporic subjectivity developed in the first part offers a language with which to dialogue with the artworks or question the way in which the complexities of belonging, home and nostalgia are expressed in the works, while the works in turn help deepen an understanding of diasporic subjectivity. Both philosophies and artworks may function as transformative, practical tools for seeking wisdom, cultivating self-awareness, developing moral character, and living a reflective and examined life. The combination of personal narratives and self-reflexive, philosophical dialogues regarding artworks and art making and its exigencies holds the potential to produce deeper philosophical insights into the fundamentally diasporic human condition. This kind of hybrid research at the interface between philosophy and artistic praxis is accessible to a broad-based audience. It is therefore better able to undo malicious stereotypical associations between émigrés and malignant tropes of societal decay on the African continent and to validate the contributions made by African diaspora to the decolonial project, than neatly distanced academic reflections, which reduce the philosophical impact of transnational migration to measurable motivations and statistics. , Thesis (D.Phil) -- Faculty of Humanities, School of Social Scinces, 2024

- Description: The French horn is an orchestral instrument with a rich history that spans centuries, undergoing notable transformations in its design and functionality. A short overview of this history is provided in Appendix A. Originating as a simple coil, the French horn has evolved to encompass a complex valve system, multiple harmonic series, and a diverse range of modifications tailored to players' preferences and requirements. These modifications include mutes, grips, extra keys, and even the exploration of different materials for mouthpieces. The use of plastic rims on mouthpieces, for reasons such as allergies, thermal conductivity, and tactile sensation, has already gained traction among horn players (Tuckwell, 2002). In the realm of manufacturing and technology, the concept of additive manufacturing has emerged as a promising avenue. Referred to as the next "industrial revolution” (Berman, 2012), additive manufacturing has become increasingly accessible through desktop-scale 3D printers. This technology offers a viable method for producing cost-effective musical instruments and enhancers without compromising quality (Kantaros, 2018). As evidenced by a 2018 Roundtable report from the South African Parliament, additive manufacturing aligns with the trajectory of the fourth industrial revolution, prompting governments to develop policies and strategies to harness its potential. Given the significance of additive manufacturing, a comprehensive investigation into applying these new technologies for the horn is warranted. Specifically, material choice, quality of sound, and the experience of performing on a printed mouthpiece is investigated and compared to a traditional metal mouthpiece. While the horn is comprised of many individual components, this study relates specifically to the mouthpiece. A brief appraisal of the significance of the mouthpiece will follow in the next section. , Thesis (MMus) -- Faculty of Humanities, School of Visual and Performing Arts, 2024

- Description: Based on the original clown prince of crime in the DC comic books, the Joker is one of the most notorious villains in cinematic history. He originated in the comic book Batman #1 (Finger, 1940) over eighty years ago, and he remains a prominent character across a myriad of media platforms. In film and television, the Joker has appeared in major and minor roles in approximately nine animated series, eighteen animated films, six live-action series, and five live-action films. Indeed, multiple roles, actors, and decades after the character’s first debut in the Batman television series (1966), the Joker continues to be well-received and sought-after, insofar as every time a new Joker is announced, the character garners more intensive publicity and the film as a whole becomes highly anticipated. Thus, what started as a simple clownish character in the role of a minor villain in Batman (1966), has evolved into a multi-faceted villain so captivating that he has recently earned his own stand-alone films, namely Todd Phillips’ Joker (2019), and the sequel, Joker Folie à Deux (2024) – where he is no longer the antagonist, but now the protagonist. In this research, firstly, key features of the Deleuzoguattarian schema relevant to this study will be presented, before capitalism – as the context of Batman’s Gotham – is considered through a Deleuzoguattarian lens. This study will delve into what makes the beloved Joker so extraordinary along with the aesthetic features associated with his meteoric rise to fame. In this regard, what will be theorized is that the Joker constitutes an example of a Deleuzean nomadic war machine: that is, a critical character who borrows aspects of the State Apparatus and then twists and shapes them into weapons through which he questions and mocks society for its authoritarian and ideological flaws, and with which he exposes its conceptual and ethical blind spots. In this way, he acts like a mirror, reflecting what is wrong with society, and by implication, with the human ‘nature’ – not only in the fictional world of Gotham, but also in the contemporary era created therein. More specifically, discourse analysis and film analysis will be used here, to engage critically with the Joker’s persona in relation to the changing contexts in which the various films were made, in order to trace the development of the character through a Deleuzoguattarian lens. As will be discussed, Phillips’ Joker (2019) signals the deterritorialization of the Joker from the ambit of Batman’s influence, and opens up the possibility for his further deterritorialization as an increasingly mobile and nomadic catalyst of critical thinking beyond even Gotham itself. Then, thirdly, an in-depth analysis on the five key cinematic Jokers will be completed in terms of the characters’ historical contexts, character backgrounds, and aesthetics. And thereafter, the deterritorializing ‘line of flight’ already underway – as by Phillips’ Joker (2019) – will be continued through the creative media production component of this study, which will entail the conceptualization, design and illustration of three new Joker manifestations, each of which will reflect critically upon failing systems in South African society across select time periods, and how these failing systems have contributed to the collective trauma of marginalized groups of people. The first South African Joker manifestation, set in the 1980s, will reflect upon the faltering political infrastructure during the Apartheid era. The second Joker manifestation, set in the early 2000s, will encapsulate the repercussions of the post-Apartheid neoliberal economic landscape. And the third Joker manifestation, set in the 2010s, will draw attention to sociocultural collapse particularly in the space of gender-based violence and sexual assault. Thus, the creation of these Jokers will act as an exploration of trauma, insofar as the tragedy and pain caused by the above-mentioned failing systems will manifest physically through their character designs. In terms of this, and in keeping with the dynamics of appropriation and inflection that are definitive of nomadic war machines, here focus will fall on how their character aesthetics pose critical questions about relevant issues in the South Africa. On account of this, although this research is by definition situated within the spectacle/performance paradigm, it also runs counter to the largely apolitical orientation of creative media production that occurs therein, through its emphasis, instead, on how such creative media production can also entail critical thought that is aimed at thematizing socio-cultural and politico-economic issues and the trauma that they create; thus, this creative media component aims to encourage a more trauma-aware society through art. , Thesis (MA) -- Faculty of Humanities, School of Language, Media and Communication, 2023

- Description: Coloured identity has been a historical point of contestation in South Africa because Colouredness is assumed as “an inbred quality that arises automatically from miscegenation while instrumentalists share the essentialist premise that coloured identity is something negative and undesirable but blame it on the racism and the exploitative practices of the ruling white minority” (Adhikari, 2009: 15). This archaic belief attributed to racial mixture has now become redundant, due to the emergence of new hybridised Coloured identities that factor other ethnic and cultural groups as well as internal and external elements into their conception. The role of Place in the formation of Coloured identities is at the core of this fine arts based enquiry. This study is located in Malabar, Gqeberha which was established after the forced removals onset by the Group Areas Act of 1950 and the displacement of residents from South End. Additionally, it considers specific locations significant in their linkages to hybridised peoples, and how the place and individuals have been influenced by historical legacies of colonisation and apartheid. These are examined to consider their function in contextualising contemporary lived experiences of Coloured identity within the community of Malabar and its effect on artistic practice through autoethnographic research. Through this autoethnographic and reflexive study and the accompanying empirical research process, I critically examine and explore my Coloured identity as part of being-in-the-world (Heidegger, 1962). This ‘being’ is multifaceted as a result of the significance of Place in South Africa and how it has shaped my perception of how and where I have a sense of being and belonging. , Thesis (MA) -- Faculty of Humanities, School Visual and Performing Arts, 2023

- Description: This study explores the perspectives and experiences of LGBTQ alumni of all-boys’ schools in the Eastern Cape. The context of increased competition between schools in the education sector and the importance of inclusion within the sector necessitated a study to investigate the extent to which relationship management is conducted with an orientation towards LGBTQ inclusion in all-boys’ schools in the Eastern Cape. Student protests in South Africa over the past 10 years have expanded concerns about student belonging beyond the widely studied lenses of race and class. A growing body of literature and wider discourse emphasises student belonging as a challenge in the South African education sector. Marginalised students continue to experience educational spaces negatively. LGBTQ student experiences in the South Africa are characterised by violence and ostracisation, thus warranting further investigation and inquiry. The study locates itself in the intersections between gender and sexual diversity and economic citizenship in the broader discourse of school inclusivity. A qualitative research approach was employed, making use of semi-structured, in-depth individual interviews. The sample was derived from alumni of all-boys’ schools in the Eastern Cape through snowball sampling. Ten LGBTQ-identifying alumni of boys’ schools in the Eastern Cape were interviewed. The findings reveal the need to question the extent to which LGBTQ alumni can enjoy the fullness of the value proposition of all-boys’ schools, and what can be done to ensure LGBTQ belonging. The findings of this study concur with existing literature about LGBTQ experiences. Participants defined their school experiences as exclusionary and characterised by fear of failing to assert themselves in a hypermasculine school environment. LGBTQ alumni of all-boys’ schools in the Eastern Cape view relationship management as under-utilised as a tool to facilitate LGBTQ belonging. Instead, relationship management is used to affirm those who fit the mould of the quintessential ‘old boy’ network, by defining the masculine behaviours that learners in all-boys’ schools are compelled to aspire towards. v ABSTRACT The findings illustrate that the culture of silence around non-confirming sexuality is sustained in the post-schooling relationship management life-cycle and results in the absence of the LGBTQ customer voice in the drafting of school strategy and policy. LGBTQ alumni who speak out about controversial issues often face admonition from their former teachers and peers. LGBTQ alumni criticise the relationship management of their former schools for the over-emphasis on fundraising and the complete absence of discussions on diversity. LGBTQ alumni are therefore marginalised in the process of value co-creation, as LGBTQ alumni feel they will never be viewed as legitimate collaborators by their former schools. The suggested recommendations emerging from this study include the need to codify school policies that speak specifically to LGBTQ marginalisation. Furthermore, schools must endeavour to make specific enquiries into LGBTQ student experiences and include LGBTQ concerns in wider school discourse. , Thesis (Ma) -- Faculty of Business and Economic 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: 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

- Description: This study investigates the intricate dynamics of music within the umgidi initiation ceremonies among the amaMpondo, focusing on the interplay between traditional and modern popular music. The study explores the cultural foundation of the umgidi ceremony, emphasising its transformative significance and the evolving influence of modern popular music, particularly among the youth. A comprehensive literature review follows, contextualising the amaMpondo, their cultural practices, and the complex relationship between traditional and popular music in the broader South African music scene. The study adopted a qualitative ethnographic approach, including participant observation and individual interviews, to explore the impact of modern popular music on traditional elements during umgidi initiation ceremonies. Thematic analysis was employed for data interpretation, ensuring a systematic exploration of patterns and meanings. Ethical considerations were meticulously addressed, emphasising protecting participants' rights and cultural sensitivity. The study's findings highlighted the multifaceted roles of music during umgidi initiation ceremonies. Music is a powerful medium for cultural expression, communication, and communal celebration. The call-and-response format, rhythm variations, and the influence of modern genres such as Gqom and Amapiano were explored. Community attitudes toward integrating modern popular music reveal diverse opinions, ranging from full embrace to resistance. In summary, this study contributes to understanding the evolving dynamics of music in umgidi initiation ceremonies among the amaMpondo. The study provides a nuanced exploration and a roadmap for future research, community engagement, and policy considerations by combining cultural insights, literature review, methodological rigour, and community perspectives. , Thesis (MMus) -- Faculty of Humanities, School of Visual and Performing Arts, 2023

- Description: It is understood that, for us humans to communicate with one another, we need language. Communication thus has a close relationship with society. But language changes and it has many varieties. On the one hand we have the standard variety of a language which is mostly used in formal situations, and on the other hand we have other varieties, which are mostly used in informal situations. Slang serves as an example of the latter and is chiefly used by adolescents – individuals between the ages of 13 and 19. As Saal and Lawrence (2019: 24) put it: young people are the agents of linguistic change. The researcher finds the language of teenagers quite interesting seeing that he is a teacher who frequently comes across words or phrases he has not heard or does not know the meaning of. The goal of this study is thus to investigate teenage language as phenomenon, with special reference to slang. This study examines slang words and expressions as they occur among teenagers in two Nxuba (formerly Cradock) schools, as well as find out why, when, and when the research group will not make use of slang. Nxuba forms part of the Inxuba Yethemba Municipality in the Eastern Cape. During the study general linguistic phenomena that occur among the teenagers in the given town are also investigated. These phenomena are analysed using the phonetic, phonological, morphological, syntactic, semantic, and lexical levels of variation. This study follows a qualitative approach with the help of questionnaires, direct observation, and focus group interviews as data collection methods. It was found that teenagers are highly creative and create novel words or give new meanings to words that already exist in the standard variety. The reasons why teenagers make use of slang is, among other things, to ease communication, for the fun of it, secrecy, and to enrich the standard variety. Slang is mostly used in informal situations and tends to be avoided in the presence of older persons, at church, and when doing schoolwork. There are also various linguistic phenomena that appear in teenagers’ general language usage: borrowing, reduction, homonyms, polysemes, and various phonological phenomena, among other. , Thesis (MA) -- Faculty of Humanities , School of Language, Media and Communication , 2024

- Description: The search for new stereoselective catalysts remains important for the isolation of enantiomeric products from racemic mixtures. The need exists for these catalysts to be more efficient, to be more cost effective as well as be stable over time without undergoing changes in molecular structure and selectivity. The purpose of this research project was to experimentally synthesise and characterise asymmetric catalysts for the use in enantioselective synthesis. The catalysts consisted of the main group element phosphorous as central atom, with the phenyl rings of mandelic acid ligands monosubstituted with halogen atoms fluorine, chlorine and bromine in different configurations. Ligand binding resulted in the formation of hydridospirophosphorane structures, from which the molecular properties and binding geometry of these molecules could be explained by the theory of apicophilicity. Characterization was performed by NMR and IR spectroscopy as well as diffraction studies that provided the experimental crystal structures. The structural, energetic and spectroscopy results were compared to the theoretically obtained molecular properties using DFT analysis. Various interand intramolecular interactions that existed between molecules found in crystal packing environments were discussed. Additional properties that were investigated included modelling solvation effects, molecular orbital analysis, Hirshfeld surfaces, orbital and atomic energy and population analysis as well as ESP energy calculations with the optimized crystal structures as input. Molecular overlay comparisons were also performed between the experimental and optimized structures where the effectiveness of various DFT functionals and basis sets could be determined. The method with the best overall cost-to-accuracy ratio was found to be the triple-zeta def2-tzvp basis set with B3LYP functional theory and the addition of Grimme’s dispersion correction. Results indicated differences in crystal packing depending largely on the given halogen atoms present in the substituted phenyl rings, with differences observed in electronegativity and steric effects. One of the crystal systems showed additional interactions with solvent molecules, giving the impression that obtaining crystal void formation was possible. Alterations in the transition state activation energies between the isomers of each molecule were found to be present and supported the theory behind the mechanism of stereochemical induction. The studied compounds were therefore effective in isolating different enantiomeric ligands by means of energy differences between conformers and displayed unique catalytic properties resulting from the phosphorous main group element. The hydridospirophosphoranes conformers responsible for the lowest theoretically calculated activation energy induced crystallization as was seen by diffraction results for all compounds. Even as an intriguing observation, crystallization will largely depend on solubility rather than a specific conformer’s amount in solution. , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2023

- Description: Digital transformation (DT) integrates technology into all business areas, fundamentally changing how businesses operate and deliver value to their clients. It is also a cultural change that requires organisations to continually challenge the status quo, experiment and get comfortable with change. Smart Municipalities in South Africa have various challenges concerning integrating services and information flow among departments within the municipalities, thus preventing the creation of value for the citizens. The ongoing digital transformation revolutionises urban development and governance, offering opportunities for enhanced citizen services, resource optimisation, and sustainable growth. However, the complexity of implementing smart city initiatives demands a structured approach. Due to urbanisation, municipal management in developing nations must deal with issues like increased energy consumption, pollution, the disposal of toxic wastes, resource depletion, ineffective management of urban infrastructures, ineffective planning processes, overloaded transportation networks, endemic congestion, as well as social inequality and socioeconomic disparity. The extent of digital adoption in the South African province of the Eastern Cape has provided municipalities with a learning opportunity to change into data-driven Smart Municipalities in order to increase productivity, growth, employment, and the need for people with a variety of skills. This study required a review of the literature to examine digital transformation, Smart Municipalities, Smart Municipalities at national and international levels, and Smart Municipality models. The literature review also helped to create a Smart Municipality conceptual model. Data for this study were collected in four Eastern Cape municipalities, namely: DR. AB. Xuma, Enoch Mgijima, Intsika Yethu Local municipalities, and their critical stakeholder Chris Hani District Municipality. The population was all municipal workers, including Municipal Managers, Councillors, Executive Management, ICT officials, Unit Managers, Computer Users and other municipal employees who were using IT to do their job responsibilities within the municipalities. This research study followed a positivistic approach using quantitative methods of analysis. Accordingly, the conceptual model was hypothesised and tested using a questionnaire to collect data and the data were statistically analysed. The study followed a descriptive research designwith a quantitative approach. Various statistical analyses were conducted, including descriptive statistics, reliability and validity metrics of the research instrument, correlation coefficients and Exploratory Factor Analysis (EFA). South Africa has provided municipalities with a learning opportunity to change into data-driven Smart Municipalities to increase productivity, growth, and employment supported by the need for people with a variety of skills. A Value Alignment Smart City Stakeholder (VASCS) model was created in previous research and identified nine dimensions of a smart city, namely Smart Economy, Smart Environment, Smart Governance, Smart Living, Smart Mobility, Smart Organisation, Smart People, Smart Policies and Smart Technology. Due to lack of DT framework and guidelines that guides municipalities on how they can adopt Smart Municipality concept, the objective of this study was to propose and evaluate a Value Alignment Smart Municipality Stakeholder (VASMS) model for municipalities in the Eastern Cape. The nine dimensions were empirically evaluated by stakeholders in four Eastern Cape municipalities. The results depict a change towards the importance of developing a Smart Municipality in the four municipalities, while following appropriate planning, designing, management, operations and governance guidelines. The respondents regarded the smart policy dimension as the most important dimension in the proposed VASMS model. This study further provided practical guidelines for the adoption of smart municipalities in the Eastern Cape Province of South Africa. This proposed VASMS model aims to address the unique challenges faced by municipalities in the Eastern Cape as they embark on their digital transformation journey. It outlines a stepby- step process encompassing strategic planning, technological integration, stakeholder engagement, and governance restructuring. Moreover, it emphasises the importance of fostering a collaborative ecosystem between government agencies, private sector partners, and citizens. By offering this VASMS model, this research contributes to the advancement of Smart Municipality initiatives in the Eastern Cape, ultimately paving the way for more efficient, resilient, and citizen-centric urban environments. , Thesis (MCom) -- Faculty of Science, School of Computing Sciences, 2023

Various statistical analyses were conducted, including descriptive statistics, reliability and validity metrics of the research instrument, correlation coefficients and Exploratory Factor Analysis (EFA). South Africa has provided municipalities with a learning opportunity to change into data-driven Smart Municipalities to increase productivity, growth, and employment supported by the need for people with a variety of skills. A Value Alignment Smart City Stakeholder (VASCS) model was created in previous research and identified nine dimensions of a smart city, namely Smart Economy, Smart Environment, Smart Governance, Smart Living, Smart Mobility, Smart Organisation, Smart People, Smart Policies and Smart Technology. Due to lack of DT framework and guidelines that guides municipalities on how they can adopt Smart Municipality concept, the objective of this study was to propose and evaluate a Value Alignment Smart Municipality Stakeholder (VASMS) model for municipalities in the Eastern Cape. The nine dimensions were empirically evaluated by stakeholders in four Eastern Cape municipalities. The results depict a change towards the importance of developing a Smart Municipality in the four municipalities, while following appropriate planning, designing, management, operations and governance guidelines. The respondents regarded the smart policy dimension as the most important dimension in the proposed VASMS model. This study further provided practical guidelines for the adoption of smart municipalities in the Eastern Cape Province of South Africa. This proposed VASMS model aims to address the unique challenges faced by municipalities in the Eastern Cape as they embark on their digital transformation journey. It outlines a stepby- step process encompassing strategic planning, technological integration, stakeholder engagement, and governance restructuring. Moreover, it emphasises the importance of fostering a collaborative ecosystem between government agencies, private sector partners, and citizens. By offering this VASMS model, this research contributes to the advancement of Smart Municipality initiatives in the Eastern Cape, ultimately paving the way for more efficient, resilient, and citizen-centric urban environments. , Thesis (MCom) -- Faculty of Science, School of Computing Sciences, 2023

- Description: A racially segregated culture historically influenced the growth of psychological testing and evaluation in South Africa. Thus, South Africa's multicultural and multilingual community poses difficulties for psychologists in their daily work. Most of the psychological tests used by psychologists are predominantly normed in either or only English/Afrikaans. Given the economic and professional resources required to develop new standardised tests for the broader South African population, the current status quo is set to continue for the foreseeable future. Consequently, language barriers pose a challenge when psychometric standardised tests are administered in a language that is different from that of the client, and as a result, psychologists must develop ways to enhance the fairness of these measures for their client base. The avenue of research that was explored is how psychologists overcome the language boundary when assessing clients who speak an indigenous first language, particularly isiXhosa. As such, this study explored this question through qualitative methods. Through purposive sampling, nine psychologists were invited to share their practical expertise on this topic, using semi-structured online interviews. The findings of this study suggested several core themes providing useful methods for other psychologists facing the same challenge, including the challenges with administering psychological tests with isiXhosa clients, the availability of standardised tests in the South African context, and the importance of determining the client’s language proficiency. Five themes with several sub-themes emerged from the study. The study contributes to the currently limited existing body of knowledge, and subsequently to the research area that this study explores - thus further providing guidelines that practitioners can employ when working with clients who are isiXhosa speaking. , Thesis (Ma) -- Faculty of Health Science, 2023

- Description: Mental illness is a global and widespread phenomenon, and its presented symptoms are experienced differently within various contexts. In many contexts, cultural beliefs are noted as influencing the thinking, feeling, and behavior of individuals and groups. Schizophrenia is often associated with a clustering of symptoms, which are often interpreted from within a cultural lens. This is in part, due to the lack of access to mental health facilities, and the limited understanding of psychological processes, but primarily due to cultural belief systems. As such, many individuals rely on indigenous knowledge systems and traditional healing when experiencing psychological symptoms. Within South Africa, the symptoms associated with schizophrenia are understood and treated in accordance with cultural beliefs and it is likely that bewitchment, spirit possession, as well as ancestral callings such as ukuthwasa, etc. will be associated with the symptoms of mental illnesses. The implications that this poses to psychological treatments and interventions are vast and require exploration. This study employed a qualitative methodology, with an exploratory and descriptive design. There were 8 participants (males= 4; females= 4), aged between 26-37 that were recruited for the study by utilizing a purposive sampling strategy, as well as a snowball sampling technique. Thematic analysis was used as a means of data analysis, by following the method by Braun and Clarke. The study applies the principles of ethics with regard to confidentiality and privacy. The findings of the study revealed that participants’ perceptions of schizophrenia were influenced by their culture. Participants of the study suggested that culture is influential in the treatment of those diagnosed with schizophrenia. Furthermore, the study revealed that there is a hierarchical system in the Zulu Culture and those diagnosed with schizophrenia are placed at the bottom. , Thesis (Ma) -- Faculty of Health Science, 2023

- Description: Feedback from students provides an opportunity to gain insights into students’ learning behaviour and participation in higher education learning and teaching. Academic staff are expected to constantly review and improve the learning and teaching environment where feedback contributes vital information toward pedagogical decision-making. Reviewing student feedback is essential but time-consuming, making it crucial to explore more effective and efficient ways to analyse and present feedback that encourages intervention and support. The general design science research evaluation pattern guided the construction and evaluation of a Feedback-Driven Architecture (FDA) for Learning Analytics (LA) to address this problem. An FDA implementation using a suitable case demonstrated each component validating the feasibility and effectiveness of the proposed design. The components identified for inclusion in the FDA were integrated within layers of a three-tiered architecture pattern. The data layer incorporates the collection, preparation and storage of learning management system data which includes free-form narrative student feedback. The application layer contains logic to support the analysis of free-form narrative student feedback and extraction of learning analytics. Arrangement and visualisation of information in the presentation layer aim to promote appropriate intervention and support. Evaluation using a case study showed that the FDA provided necessary guidelines for developing an implementation that produced feedbackdriven learning analytics. Data preparation transformed unstructured data into a suitable representation for effective analysis. Cohorts within narrative feedback responses were identified using the k-means clustering algorithm and latent Dirichlet allocation. Logistic regression and support vector machines were applied as predictive models and trained using extracted quantitative markers to predict academic success. , Thesis (MSc) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2023

- Description: Quality in higher education is a complex and evolving concept that has been a subject of measurement, assurance and promotion in universities globally for the past three decades. However, its precise definition remains elusive due to its fluid nature, influenced by various contextual factors and stakeholder perspectives. This study explored the concepts of quality teaching and quality learning within the specific context of Nelson Mandela University, focusing on two critical internal stakeholder groups, lecturers and students. By maintaining a constant context, the study sought to gain a deeper understanding of how these stakeholders perceived and contributed to the overall quality of education at the institution. Defining quality in higher education (HE) is important, as it directly impacts on the evaluation processes within educational institutions. Presently, most Higher Education Institutions (HEIs) assess quality using tangible inputs and outputs, resulting in a quantifiable representation of quality. Despite this approach, realistically, the anticipated improvements in the quality of teaching and learning are not apparent, leading to concerns about graduate readiness for the demands of the workforce. This situation raises imperative questions about the quality of teaching and learning within HEIs, necessitating a response to address this issue. This study used the conceptual model Schindler et al. (2015) developed to investigate stakeholder perceptions of quality teaching and quality learning in higher education (HE). The research followed a novel perspective by uncoupling quality in HE from the prevailing neoliberal approach and considering quality in HE within social inclusion interventions (Gidley et al., 2010a) already in place in HE settings. The research methodology expanded on social inclusion theory and employed a qualitative, participative and visual approach adapted from Mmogo-method®, an indigenous method. The research design fostered active participation from the participants, who assumed the role of co-researchers. Participants constructed their answers to the research question using unstructured materials, subsequently sharing, explaining, and interpreting their viewpoints within the group setting. , Thesis (PhD) -- Faculty of Education, School of teaching and learning, 2023

- Description: This study uses multi-temporal remote sensing data to spatially visualise and quantify land degradation due to mining as well as Calcrete Bontveld rehabilitation at the Grassridge PPC Cement mine, Gqeberha formerly known as Port Elizabeth in the Eastern Cape, South Africa. Botanical field data is also used to verify the suasses of rehabilitation in the area. SPOT-6 and Landsat multi-spectral images were compared, and Support Vector Machine and Random Forest algorithms were used for classification in order to determine which yields more accurate results for a limestone mine. Support Vector Machine analysis using SPOT-6 images yielded the best results. This was due to the high spatial resolution of SPOT-6 compared to Landsat and Support Vector Machine classifier was able to classify images with fewer training points compared to Random Forest. The spatio-temporal land cover change at the mine was then determined between the years 2000, 2015 and 2020. Land cover classification is useful for monitoring land degradation and, in this case, was able to show the extent of rehabilitation success. For the year 2020, a 17% area was rehabilitated; however, the algorithm could not distinguish between unmined Calcrete Bontveld matrix and rehabilitation sites that were older than five years. The performed change detection also showed that 29.50% of unmined Calcrete Bontveld matrix had changed to “mature rehabilitation” (rehabilitation sites older than five years). Again, for this percentage in some areas the algorithm could not distinguish between the unmined Calcrete Bontveld matrix and rehabilitation sites that were older than five years due to high similarities between the two land cover types. Area changes of the different land cover classes could also be used to demonstrate how rehabilitation areas have matured over time and lead to the conclusion that most of the Calcrete Bontveld which was mined, has over the years been successfully rehabilitated. Vegetation analysis was conducted to further validate the rehabilitation success of Calcrete Bontveld matrix. Multivariant Detrended Correspondent Analysis showed that rehabilitation sites which were younger than five years (2–year-old rehabilitation plots that were sampled) had great dissimilarity to the natural unmined Calcrete Bontveld matrix and that rehabilitation sites older than five years, in this case 16–years older, had high similarity and resemblance to natural unmined Calcrete Bontveld matrix and therefore could be considered as being mature. This was a more definitive assessment as it considers all aspects of the vegetation. Species cover and species richness also showed that Calcrete Bontveld matrix rehabilitation sites which have been rehabilitated for more than 5 years had greater similarity to natural unmined vegetation compared to areas that have been rehabilitated for less than five years. This study, therefore, demonstrates that due to the high similarity between mature rehabilitation sites and unmined Calcrete Bontveld, rehabilitation has been successful. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2023

- Description: Seabirds are one of the most threatened groups of birds under both marine and terrestrial pressures. Among seabirds, the Cape gannet Morus capensis is a southern African endemic species facing several pressures of anthropogenic origin, including competition with industrial fisheries on small pelagic fish stocks. Cape gannets, being a long-lived species that is sensitive to environmental changes, are sentinels of change in oceanic environments granting it important to understand which factors influence their foraging behaviour and breeding outputs. For example, factors like age can result in a loss of physical capabilities which can lead to behavioral compensation and subsequent changes in chick provisioning rates and amounts. With the current fisheries management the fish stocks are continually decreasing, indicating the importance of an updated fine-scale assessment on the spatiotemporal overlap between foraging gannets and fisheries. The first objective of this thesis was to determine the influence of adult Cape gannets’ age and sex on their foraging characteristics and energy expenditure during foraging. I equipped chick-rearing Cape gannets of known age and sex with a 3D accelerometer and GPS device. Foraging effort (trip duration, foraging path and maximum distance to the nest) did not differ between sexes nor with age in Cape gannets. Both sexes rested less on the water with age. Aging females also spent more time in flight than males. The age- and sexual differences in energy expenditure prevalent in our study might reflect niche and/or risk partitioning strategies to ensure adequate provisioning to the chick. The second objective of this thesis was to determine the influence of fisheries catch rates, sardine and anchovy biomass, and adult foraging effort on chick growth rates in Cape gannets, using a long-term dataset collected between 2005 and 2020 on Malgas Island. I equipped chick-rearing adults with a GPS device and I weighed the chicks for between 3 to 6 increments to calculate the average daily mass increment. Of all the variables, foraging trip duration was the main determinant of daily growth rates, with chicks benefitting from parents’ shorter foraging trip durations. Chicks tended to grow slower when fisheries catch of sardine and anchovy were higher, possibly an effect of competition with fisheries. Chicks also grew faster when fish biomass was higher. This long-term monitoring demonstrated the possible effect of food competition between Cape gannets and fisheries, with negative impacts on gannet fitness as determined via chick growth rates. The third objective of this thesis was to determine the influence of both the biomass and fisheries catch rates of sardine and anchovy on Cape gannet foraging effort at a spatial and temporal scale. This was achieved by equipping a total of 668 chick-rearing Cape gannets with a GPS device. With an increase in fisheries catch there was an increase in the birds’ foraging effort. To reduce competition between the gannets and fisheries, the gannets’ core foraging areas seldomly overlapped with the fisheries catch locations, at the cost of the gannets’ increased foraging effort. One method to halt the Cape gannet population decline would be to conserve the fish resources close to the breeding colonies. This would reduce the birds’ foraging whereby increasing their fitness. Safeguarding small pelagic fish to ensure the perseverance of the remaining Benguela seabird populations, would lead to preserving the Benguela marine ecosystem as a whole. My study provided new insight into effects of fish stock management on Cape gannet foraging behaviour in South Africa, and the need for adequate management to ensure population persistence. , Thesis (PhD) -- Faculty of Science, School of Environmental Sciences, 2023

- Description: ntestinal parasites also known as parasitic worms are one of the common water, soil and feacal transmitted infections of public importance in the world. This study evaluated the Knowledge, Attitudes and Practices (KAP) of public workers comprising EPWP and CWP general workers on intestinal parasites in a selected municipality in the study area . Additionally, using secondary data, the researcher established the prevalence of intestinal parasites in Sarah Baartman District Municipality (SBDM) from 2012 to 2020. Method: The study made use of a quantitative, cross-sectional research design resembling a study by S.D. Hambury .A structured questionnaire, closed-ended, telephonically-administered questionnaire was used to collect data from 160 Expanded Public Works Programme (EPWP) and Community Work Programme (CWP) general workers. Data on the prevalence was obtained from the SBDM National Health Laboratory Service (NHLS). Data was analysed using both inferential and descriptive statistics using SPSS software version 16.1, inferential statistics tests used were Chi2 square tests and p-value tests. Descriptive statistic tests used included frequency distributions, percentage, cumulative percent, and valid percent. Results: The participants’ overall awareness, attitudes and practices of the study were poor, 64.4% of the study participants had the correct knowledge about intestinal parasite infections. The age of study participants and who the participants thought was at risk of being infected by intestinal parasites had a non significant relationship (p>0.05). Gender and the responses to who is at risk of getting infected with intestinal parasites had a statistically significant (p<0.05) relationship. Intestinal parasite prevalence from 2012 to 2020 in SBDM was 46.37% which means it was close to half of the sampled population. Males had the highest prevalence as compared to females, with a prevalence of 53.1% xvi in males and 46.9% in females. The highest disease infection was found between ages one and six years. Conclusion: The researcher concluded that the overall awareness, attitudes and practices on intestinal parasites in SBDM were poor. The intestinal parasites present in SBDM were Cytoisospora belli (35.4%) and Giardia lamblia (35.4%), Ascaris lumbricoides (17.7%), Trichuris trichiura (3%), and Taenia species (2%). The study also revealed that the prevalence of intestinal parasites was low from 2012 to 2020. Recommendations were made with an emphasis on education to increase disease prevention and control awareness. , Thesis (Ma) -- Faculty of Health Science, 2023

- Description: ntestinal parasites also known as parasitic worms are one of the common water, soil and feacal transmitted infections of public importance in the world. This study evaluated the Knowledge, Attitudes and Practices (KAP) of public workers comprising EPWP and CWP general workers on intestinal parasites in a selected municipality in the study area . Additionally, using secondary data, the researcher established the prevalence of intestinal parasites in Sarah Baartman District Municipality (SBDM) from 2012 to 2020. Method: The study made use of a quantitative, cross-sectional research design resembling a study by S.D.

- Description: In South Africa, the government subsidises the building of starter homes to meet the demand for housing for people with lower incomes. However, it is necessary for the state to revise its efforts to meet the demand for housing in the country. Self-help housing is a model that can be used as an alternative to state housing subsidies. The present research study investigates the essential aspects of sustainable self-help housing in the central region of South Africa. The present study aimed to address the central research topic by eliciting responses from participants: How can self-help provision become sustainable in the central region of South Africa? In response to the question, an effective self-help housing support model was developed, the aim of which is to outline how self-help housing projects could be improved. The literature findings demonstrate the potential of this model as a viable alternative to the existing housing delivery mechanism in South Africa. This assertion is supported by a study of self-help housing trajectories and an examination of relevant South African housing policies. However, there has been a lack of emphasis on the simplification of current models to accommodate the needs of implementers, government entities, and beneficiaries of self-help housing initiatives. This study aimed to address the highlighted gaps by utilising a qualitative methodology and drawing upon the data obtained. The data collection techniques included semi-structured interviews, structured observations, and focus-group discussions. A total of 25 semi-structured interviews were conducted with key stakeholders in human settlements, while the focus-group discussions involved 50 participants. A total of 5 focus group discussions were conducted with each group consisting of 10 participants. Moreover, the researcher conducted a document analysis, observations, and questionnaire survey. The data collected were analysed thematically. The results revealed that there are still challenges with implementing self-help housing. Moreover, the results are attributed mainly to a mismatch of the roles and responsibilities and not understanding the Enhanced People’s Housing Process (EPHP) policy. The principal contribution of the thesis is that housing policies, programmes and sector plans must encourage beneficiaries to play an active role. This study found that weak or unclear project vi specifications lead to contractor misunderstandings or discrepancies in housing project implementation, resulting in poor-quality work or delays. The conventional contractor-driven housing-delivery model also has issues like poor construction, corruption and mismanagement, profit-driven contractors, high contractor rates, project delays/incomplete projects, illegal occupation of incomplete projects, riots and disputes, ineffective project specifications, and beneficiary disengagement. In this study, it is demonstrated how a positive social impact on housing could be the outcome of an improved self-help approach. Consequently, the research suggests the adoption of an effective self-help housing support model, which may effectively address the challenges posed by informal settlements while enhancing the execution of self-help housing projects. The model has the potential to make contemporary contributions to the public housing policy model in South Africa. This study contributes to the broader discourse on sustainable housing alternatives, providing insights into the various obstacles, potential advantages, and recommended strategies within the realm of selfhelp housing. The study's qualitative approach facilitated a comprehensive examination of the lived experiences and viewpoints of diverse stakeholders. This yielded valuable insights that can inform policymakers, practitioners, and communities in their efforts to improve the sustainability of self-help housing solutions in the central region of South Africa. , Thesis (PhD) -- Engineering, Built Environment and Technology, 2023

- Description: The aquifer systems in Gqeberha are poorly understood due to a lack of groundwater studies within the area, and this is particularly the case for the coastal aquifer of Gqeberha. Amidst the water crisis the city is currently facing, groundwater has become crucial, with over 1000 boreholes reportedly drilled in the coastal area, most of which are residential. This has resulted in the need to conduct more groundwater studies in the area and in Nelson Mandela Bay. This study presents a detailed hydrogeological characterization of the coastal aquifer of Gqeberha. This was achieved through the use of different techniques, which include field mapping, geophysics, hydrochemistry, and pumping test analysis. The work was done on the coastal seeps of the Algoa Group Formation and the fractured aquifer of the Peninsula Formation. The results through mapping indicated an abundance of folds, faults, and fractures which all have implications for groundwater flow. The majority of fractures are striking in the NE-SW and NW-SE directions. The pumping test analysis also indicated fractal flow with significant matrix flow resulting in a dual porosity system up to at least 200m in depth. The transmissivity and storativity values range from 6.78 – 44.5 m2/day and 0.0172 – 0.0325, respectively. This is highly dependent on the fracture interconnectivity, which varies across the area and is higher at shallow depths, as suggested by the geophysical profiles. Geophysical profiles indicate that the contact between the Algoa Group Formations and the Peninsula Formation results in coastal seeps due to the difference in hydraulic conductivities. The hydrochemical analysis suggests that the seeps generally have Na-Cl and Ca-Mg-Cl water types. The groundwater in the eastern area has a Ca-HCO3 water type, and the groundwater in the western region has a Ca-Mg-Cl water type, with the Chelsea-Noordhoek Fault system separating the two groundwater signatures. Groundwater at greater depths has a Na-Cl water type with higher TDS values. The chemical signatures seen are due to external factors, which include sea sprays, anthropogenic activities, rock-water processes, and possibly connate water in the Peninsula Formation aquifer. The findings of this study offer valuable insights into the present conditions of the aquifer in Gqeberha. This research serves as a foundational study that can provide a baseline for future hydrogeological investigations in the area. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2023
