- Description: Humans inhabiting the glacial refugia of the Cape Floristic Region during the Middle Pleistocene are believed to have relied on underground storage organs (USOs) as a crucial carbohydrate source. While previous research has highlighted the nutritional potential of these plants for early human gatherers, such studies are typically conducted under modern climatic conditions and do not account for the reduced plant productivity and USO yields associated with the lower atmospheric CO₂ concentrations characteristic of Pleistocene glacial periods. To evaluate the impact of CO₂ availability on plant productivity, I cultivated two Oxalis species—O. pes-caprae and O. punctata, both known to have been harvested by early foragers—under CO₂ concentrations ranging from 180 ppm to 400 ppm. Results showed that glacial-level CO₂ concentrations significantly reduced bulb production in O. pes-caprae and photosynthetic rates in both species. Using these findings to model Pleistocene foraging behaviour, I estimate that human foragers would have needed to spend an additional 8 hours gathering food to meet their daily dietary requirements of 2000 calories, suggesting the need for alternative food sources to supplement their diet. These findings emphasise the importance of considering historical plant growth conditions, particularly atmospheric CO₂ levels, when reconstructing past human diets. Failure to account for these factors may represent a significant gap in our understanding of human subsistence strategies during glacial periods. , Thesis (MSc) -- Faculty of Science, Botany, 2025

- Description: South Africa has the largest number of Human Immunodeficiency Virus (HIV)-positive people in the world, the third-highest rate of Tuberculosis (TB) infections, and the second-highest rate of Multi-Drug Resistant TB (MDR-TB) globally, with up to 60% of HIV-positive healthcare users (HCUs) infected with TB as a co-infection. Both HIV/AIDS and TB require strict medicines adherence for disease management or treatment respectively; however, this is often not attained, and as such these statistics also represent lives affected by or lives lost to these diseases. Moreover, in South Africa, up to 80% of healthcare consultations are conducted through a second language. Despite language policies suggesting the contrary, African languages are neglected in healthcare provision in South Africa. This perpetuates inequalities within the South African healthcare system by limiting HCUs understanding of and agency in their own healthcare and maintaining a barrier to more effective treatment. Such language barriers may also result in HCUs defaulting on treatment. Added to this, the fear and mistrust arising from language power dynamics contributes to high rates of avoidance behaviour. This research therefore aimed to (a) explore how healthcare professionals (HCPs) and HCUs communicate when they are not fluent in the same language in care for HIV/AIDS and TB patients; (b) develop practical and feasible strategies that would enable HCPs to address language barriers in their consultations for HIV and TB and (c) to empirically evaluate these strategies in a pilot feasibility trial in the Eastern Cape. The first aim (a) concerning the problem of language barriers in healthcare consultations was addressed through identifying communication barriers experienced by HCPs in South Africa, exploring the strategies used to navigate or alleviate these barriers, creating and implementing communication resources, and analysing the effects of these resources on HCPs’ communication. A selective narrative review was conducted (Chapter 2) to identify the main communication problems experienced by HCPs and HCUs, as well as the main communication strategies and resources used by HCPs to reduce these communication problems. This was further explored by conducting two needs analyses with HCPs (n=31) in South Africa, and specifically in the Eastern Cape, which revealed differing perspectives on health communication and confirmed HCPs’ need for communication resources. For the second aim (b), existing communication resources were reviewed and selected or further developed following a Participatory Action Research approach, and then (c) empirically evaluated in a pilot feasibility trial with six healthcare sites in the Eastern Cape. Both the needs analyses and the pilot feasibility trial were adapted to employ an online or blended approach due to COVID-19-related limitations. The feasibility and acceptability of both the study protocol and the proposed communication resources were evaluated. Three major findings emerged from this research. First, this research echoed existing literature confirming that HCPs do not have the support they need at a structural level. Second, while it was found that there is no one-size-fits-all solution for resources and training to improve HCP-HCU communication, it was noted that the most appropriate resources are those that are flexible, and those that support HCPs’ language learning. HCPs who were already sensitive to communication barriers and were already taking steps to improve their second language (L2) proficiency also took initiative to use the resources in ways other than those suggested in order to best support the communication needs of them and the HCUs they consulted. Third, and linked to the second finding, it was found that communication resources that covered conditions including, but not limited to, HIV and TB were more appropriate. HCPs who used the resources showed a small, although not statistically significant, increase in communication satisfaction, satisfaction with resource support, and trust after using the resources for one month. Although implementation problems were encountered in some settings of the intervention, it was found that this intervention has the potential to be further evaluated in a larger, multi-site randomised controlled trial (RCT). These findings inform recommendations which are made to improve the feasibility of such a study in order to conduct an RCT; to further develop the resources in order to enhance communication between HCPs and HCUs both in HIV and TB consultations and in other fields of healthcare; and to implement a similar intervention at the university level and as Continuing Medical Education. The insights gained into HCPs’ support for language support resources, which resources were used, and particularly how they were used, are significant for taking actionable steps in supporting HCPs’ provision of more equitable healthcare in multilingual South Africa. , Thesis (PhD) -- Faculty of Humanities, Languages and Literatures, 2025

- Description: This study investigates the tonalite-trondhjemite-granodiorite (TTG) suite and associated amphibolite xenoliths of the Stolzburg pluton at Crushers’ Quarry in the Barberton Granitoid-Greenstone Terrain, South Africa. Through detailed field mapping, petrography, geochemical analysis, δ¹⁸O investigation of quartz, and U-Pb zircon geochronology, the petrogenesis and geodynamic context of these Archean rocks were explored. Five major lithologies were identified: Coarse-grained trondhjemites, medium-grained tonalites, fine-grained tonalites, granodiorite sheets, and amphibolite xenoliths. Field evidence, including cross-cutting relationships, indicates that the coarse-grained trondhjemites intruded as the earliest phase, followed by medium-grained tonalites, which were then followed by fine-grained tonalites, and finally, granodiorite sheets, which represent the latest intrusive phase. Petrographic analysis reveals mineralogical differences between the trondhjemites and tonalites, with trondhjemites lacking hornblende and having lower mafic mineral content. Geochemical data support the interpretation that the TTGs formed through partial melting of variably hydrated metabasaltic sources (possibly at depth in the garnet stability field). The metabasaltic melt incorporated varying proportions of older, intermediate trondhjemite crust and volcaniclastic sediments during ascent and emplacement to form the Stolzburg pluton TTG suite of rocks. Elevated (above mantle) δ¹⁸O quartz values of the Stolzburg pluton TTG rocks ranging between 8.72 to 9.71‰ combined with it’s strongly peraluminous geochemical composition indicate the presence of an ancient crustal component that was assimilated into the metabasaltic melt source(s). It is proposed that a number of petrogenetic factors controlled the composition of the Stolzburg TTG rocks, including composition of the metabasalt source, degree of hydration of the metabasalt source and the extent of crustal contamination with older, pre-existing intermediate composition rocks. A possible candidate for the crustal contamination component could be the older 3.509 Ga Steynsdorp trondhjemite as well as ancient volcaniclastic sediments in the greenstone belt. The protolith to the amphibolite xenoliths occurring within the TTG suite are geochemically characterized as komatiitic basalt, recording either a subduction zone or crustal contamination geochemical signature. U-Pb zircon dating of the coarse-grained trondhjemites and medium-grained tonalites yield Concordia ages of 3429.9 ± 12 Ma (2σ) and 3414.0 ± 14 Ma (2σ), respectively. These Concordia ages represent an estimate of the igneous crystallization ages of the zircons and confirm that these TTGs were emplaced in close temporal succession. The U-Pb zircon ages are comparable to those in the published literature, although one sample with a significantly younger age is attributed to zircon open-system Pb-loss in complex early Archean zircons and also challenges with the LA-ICP-MS analytical technique used. The depth of metabasalt melting is not constrained in this study, similar to recent studies on early Archean TTGs. Various TTG geodynamic settings are explored ranging from melting at the base of a thick oceanic plateau to generation at depth in a subduction zone. In light of recent regional field observations, metamorphic constraints, apatite thermochronological data, U-Pb detrital zircon data and greenstone belt metabasalt geochemistry, a model of TTG crust generation in an episodic proto-subduction zone, involving subcretion and tectonic imbrication of oceanic lithosphere at c. 3.45 Ga, is considered. , Thesis (MSc) -- Faculty of Science, Geology, 2025

- Description: Dynamic capability-enhancing technology, Subject Matter Experts (SMEs), System Experts (SEs) in planning and forecasting, and big data used for sensemaking combine to enable knowledge-based management decisions in interdisciplinary teams, increasing competitive advantage. This research extended Contingent Resource-based Theory CRBT by focusing on visualization’s role in this process. SMEs and SEs configure assumptions, with visualizations, in an interdisciplinary team to enable planning within the context of legal practice management systems. The study employed a mixed-method sequential explanatory design. An initial quantitative component determining which types of decision-making information technology contribute to the competitiveness of a firm was undertaken. Niche systems were found to increase technological dynamic capability through their highly configurable workflow tools, which provide customization capabilities and the ability to react to a changing environment quickly. Niche systems differentiated through process automation were found to be the aspect to focus on in a qualitative research study. A knowledge-sharing process model was developed from the literature, and this was overlayed with visualization as the new knowledge-sharing enabler. Then, a thematic qualitative study of interviews focusing on SMEs' and SEs' use of visualization in legal and financial system implementation was employed to establish the extent to which this process occurs in legal financial transformation projects. Seven subject matter experts and four system experts in legal transformation implementations were interviewed regarding using visualization to facilitate communication, verification, and process configuration during the knowledge-sharing process. The research illustrated how (1) low code systems data, (2) people, and (3) data enable the creation, sharing, and configuration of knowledge in practice in the legal practice management context. Recommendations for further research were made to automate refining budgeting and forecasting assumptions. This enables management to arrive at more accurate forecasts by refining assumptions and producing the resultant profit and loss reports visually in heat maps depicting variance between the forecast and actual profit and loss reports. The SMEs provide feedback, and the system cycles between multiple assumption iterations, reducing the variance and enhancing management decision-making. Visualization was found to assist the knowledge-sharing process through (1) verification, (2) process enablement, and (3) communication for decision-making. This research highlighted the value of variance heat maps and other visualizations and workflows in making planning assumptions explicit, thereby enhancing forecasting accuracy. , Thesis (PhD) -- Faculty of Commerce, Rhodes Business School, 2025

- Description: South Africa has one of the highest rates of gender-based violence (GBV) in the world. This includes femicide, rape and intimate partner violence. Scholars and activists in the space of GBV have challenged society to alter the way we have been taught to engage with rape and gender-based violence. Despite many interventions, gender-based violence remains an intractable social problem. This study uses Lipari’s (2014) concept of “listening otherwise” to respond to the challenge. By interrogating how South Africa’s violent history and patriarchal society has been normalised, the study attempts to see beyond the narrow ideas prescribed by the country’s history and violent cultures. This study uses the grounded theory approach (Glaser & Strauss 1967) to investigate the relationship between listening and gender-based violence in South Africa. The concept of “listening otherwise” is explored alongside the concepts “voice”, “speak out” and “break the silence” that are the most visible and codified strategies in the fight against gender-based violence. Following the exploration, the study then develops a theoretical and methodological framework for “listening otherwise” in the spaces, fields, and engagements that deal with gender-based violence in South Africa. The two central questions of the study ask; how do we reshape the collective emotional response to patriarchal structural violence? And furthermore, how do we listen otherwise when faced with experiences of gender-based violence in South Africa? The data used to construct the framework includes in-depth interviews, studies of actual cases, academic literature, news interviews and newspaper articles. There are a multitude of ways in which people are talking about gender-based violence, exposing perpetrators and “breaking the silence”. There is, in fact, no silence around rape, gender-based violence and femicide. The silence exists around engagements about gender, misogyny and patriarchy when discussing the causes of gendered violence in the country. This research found that the public’s listening practices around gender-based violence are shaped by patriarchal cultures and rape myths which are endemic in media discourses, legal discourses and in general social talk. Building a caring society, in which people play and use restorative justice practices, may alter the communal listening practices and have an impact on the public response to gender-based violence. The framework for listening otherwise, that emerged as a result of the research, is a contribution to listening scholarship and the activism against gender-based violence. The framework considered various aspects of listening and the field of gender-based violence and arrived at six conceptual considerations and six actions for listening otherwise. , Thesis (PhD) -- Faculty of Humanities, Journalism and Media Studies, 2025

The two central questions of the study ask; how do we reshape the collective emotional response to patriarchal structural violence? And furthermore, how do we listen otherwise when faced with experiences of gender-based violence in South Africa? The data used to construct the framework includes in-depth interviews, studies of actual cases, academic literature, news interviews and newspaper articles. There are a multitude of ways in which people are talking about gender-based violence, exposing perpetrators and “breaking the silence”. There is, in fact, no silence around rape, gender-based violence and femicide. The silence exists around engagements about gender, misogyny and patriarchy when discussing the causes of gendered violence in the country. This research found that the public’s listening practices around gender-based violence are shaped by patriarchal cultures and rape myths which are endemic in media discourses, legal discourses and in general social talk. Building a caring society, in which people play and use restorative justice practices, may alter the communal listening practices and have an impact on the public response to gender-based violence. The framework for listening otherwise, that emerged as a result of the research, is a contribution to listening scholarship and the activism against gender-based violence. The framework considered various aspects of listening and the field of gender-based violence and arrived at six conceptual considerations and six actions for listening otherwise. , Thesis (PhD) -- Faculty of Humanities, Journalism and Media Studies, 2025

- Description: The manufacturing sector is a significant economic multiplier due to its strong connections to the economy's downstream and upstream output sectors. It supports the notion that manufacturing drives industrialisation and can serve as the primary engine for growth and employment creation. Despite its importance, the manufacturing sector has challenges associated with diminishing size and lack of competitiveness, especially in countries such as South Africa. These challenges are exacerbated by prevailing operational uncertainties that negatively impact manufacturing firms. Literature on operational uncertainty, fourth and fifth industrial revolution technologies and organisational learning show several interrelated theoretical and methodological gaps, highlighting three empirical and theoretical gaps as well as two methodological gaps. Six propositions were developed to investigate the research objectives. This was done using a multi-method quantitative design based on the post-positivist paradigm, with data collected from 22 experts (expert survey) and 262 firm representatives (firm survey). The results of the study confirmed that operational uncertainty is a multi-dimensional construct with a reflective model for dimensions and reflective-reflective for higher-order construct. This means that for the dimensions, the indicators can be added or excluded in the formation of the dimension. The same is also true for construct, operational uncertainty. The results of the present study also confirm that operational uncertainty is a norm in the manufacturing industry with a Manufacturing Operational Uncertainty Index (MOUI) = 0.752, indicating the range of futures. This posits that it is difficult to divide these futures into a discrete and exhaustive set of possibilities due to the complexity of conditions (variables) at play. Industry 4.0 and 5.0 technologies and their capabilities can manage the operational uncertainty dimensions with these technologies capable of scenario planning and supply chain integration (SPSI), flexible production and mass customisation (FPMC), real-time system and process monitoring and response (RPMR), root cause analysis and sustainable solutions (RCAS). These technologies are mainly artificial intelligence (AI), Internet of Things (IoT), big data analytics (BDA) and to a less extent advanced robotics (ARB), blockchain and augmented and virtual reality (ARVR). Organisation learning is also an effective causal condition to incorporate in managing operational uncertainty with Industry 4.0 and 5.0 technologies. The study has both theoretical and methodological contributions. In theory, it advanced the modified neo-configuration theory, while the methodology provided an Manufacturing Operational Uncertainty Index and integrated fsQCA with fuzzy decision-making trial and evaluation laboratory (DEMATEL), and structural equation modelling partial least square (PLS-SEM). This research study is important since the recognition and dissemination of subjects within the field of operations management hold great significance for firms, which is contingent upon their sector of operation. This research offers valuable insights for academia, policymakers, and the manufacturing sector. It helps with their activities to effect meaningful change in day-to-day business operations, allowing for more effective progress in the subject area, and promoting practical, real-world issue-solving. , Thesis (PhD) -- Faculty of Commerce, Rhodes Business School, 2025

- Description: This thesis revisits some types of normal spaces, namely, β-normal spaces and α-normal spaces, which were introduced by Arkhangel’skii and Ludwig in 2001. We study some properties of these spaces with a focus on improving some of the already existing properties and exploring new properties that are not available in the literature. Under β-normal spaces, among other things, we characterize these spaces using some types of open sets. We use the ultrafilter space to answer Murtinova’s question about the existence of a β-normal and regular space which is not Tychonoff. α-normal spaces are described in terms of countable open sets, a result imitating that of normality. It turns out that continuous functions which are onto, open and closed preserve β-normality, while those which are injective, open and closed reflect α-normality. The notion of β-normal spaces is extended to the category of bitopological spaces where we characterize these bitopological spaces simultaneously in terms of i-open sets, (i, j)-preopen and (i, j)-α-open sets. We study the interrelations of these spaces with other bitopological spaces. , Thesis (MSc) -- Faculty of Science, Mathematics, 2025

- Description: Guinea grass (Megathyrsus maximus) is a tall-statured C4 grass with a native range spanning sub-Saharan Africa. Intentionally exported for centuries for its grazing value, it has become a near-global invasive. Texas, USA is the first territory to initiate a biological control program for Guinea grass, targeting an invasive population with genetic origins that have been traced to South Africa. This study focuses on the identification and evaluation of biological control agents for Guinea grass. Native-range natural enemy surveys were performed in South Africa, resulting in the identification of several undescribed species of phytophagous midges (Diptera: Cecidomyiidae) on Guinea grass, including stem-galling taxa (gall midges) and seed-feeding taxa (seed midges). These taxa are expected to be highly host-specific based on the known biology of this family of insects, but the difficulty of rearing them in the laboratory necessitated field-based assessments. Field host range assessments of stem gall midges resulted in the rejection of one candidate (the horn gall midge, undescribed sp.) due to feeding on a relative of the target plant, Batochloa deusta, and the prioritization of another candidate (the blister gall midge, Arabukodiplosis vesicaria) that feeds only on Megathyrsus maximus. Combined field host range evaluations and phylogenetic analysis of a cryptic species complex of seed midges resolved this as a new genus containing up to seven species, with five species that are likely to be specific to their respective Panicoideae grass hosts, including Megathyrsus maximus and Cenchrus ciliaris (buffelgrass – also invasive in the USA). Climate matching models for the blister gall midge and seed midge on Guinea grass predicted high likelihood of establishment and nearly complete coverage of invaded sites in Texas, and identified northern KwaZulu-Natal, South Africa as an ideal source region for Guinea grass biocontrol agents. The nascent sub-field of grass biocontrol research has developed slowly because of inaccurate perceptions that grasses lack host-specific herbivores, and faces a severe taxonomic impediment given the large number of undescribed insect species feeding on grasses, especially in Africa. This study has contributed to resolving both challenges by identifying several new host-specific insect species, showing that the prospects for future success and discovery in grass biological control are promising. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2025

- Description: Despite global trends towards creative and productive musical learning, there is little available research on how to support music educators’ efforts to adopt productive praxis in piano lessons in primary schools, and none situated in South Africa. This climate of pedagogical innovation makes possible a turn to play-based teaching methods emerging from the global north, which are aligned with African traditions of knowledge transmission in which agentive participation in authentic cultural processes is of greater value than evaluative judgements of ensuant products. The literature advocates the cultivation of music learning ecologies that privilege learner agency through composition, yet practical means of doing so within established conventions of instrumental music tuition in South African primary schools are not provided. This thesis investigates how such an ecology might be cultivated in a primary school in the Eastern Cape, with particular emphasis on how this can be achieved without compromising established pedagogical practises that are oriented toward the attainment of important external benchmarks of musical achievement. A design-based study was conducted in a primary school over the course of 12 months, in which nine young students composed their own music during piano lessons through collaborative activity in which they were afforded a degree of autonomy in their work as they acquired and consolidated knowledge of music through its creation. A play-based teaching intervention was devised, which was iteratively enacted, analysed, and redesigned through three research cycles. This resulted in findings that drove the development of a framework for teaching composition in this context, as well as tangible teaching materials. Results show that this adapted play-based model is an effective vehicle for fostering an agentive music learning ecology in piano lessons in an Eastern Cape primary school and suggest that it is reasonable to expect similar success in comparable school contexts. The insularity of a single school setting limited this research in terms of broader applicability, so further trialling of the proposed framework is recommended in a range of school situations in South Africa and beyond to establish transferability. , Thesis (PhD) -- Faculty of Humanities, Music and Musicology, 2025

- Description: This dissertation explores the dynamic nature of cultural productions and the perpetual flux in everyday experiences within Zimbabwean social and cultural spaces over the past two decades. Amid Zimbabwe’s contemporary techno-economic milieu, there has been a remarkable surge in literary works initially tailored for print readership, then adapted for digital platforms. This shift reflects broader changes in the country’s cultural production, where the interplay between traditional publishing and digital innovation has opened new avenues for literary expression and access. The overarching goal is to investigate the connection between contemporary short fiction in Zimbabwe and the material processes of transformation and reproduction across various historical periods, forms, contexts, and platforms. It focuses on print and digital archives characterised by ephemerality, aesthetic disobedience to established norms, and the deconstruction of conventional narrative structures, motifs, and characters. These creative processes thrive on borrowing, sampling, and remixing elements from orature, novels, short stories, music, and films. The study argues that these adaptive modifications empower writers to experiment flexibly and capitalise on their literary content. It includes an interpretive analysis of short stories written in English by marginalised writers, published in print magazines such as Parade, Moto, and The Sunday Mail Magazine, as well as on digital platforms like blogs and Facebook. The primary objective is to illustrate how contemporary writers use fictional depictions of everyday life to interrogate prevalent themes like survival, circular migration, venality, occultism, and sexuality. The theoretical framework draws on the concepts of everyday living by De Certeau (1984), Newell and Okome (2013), and Adesokan’s (2023) technologies of reuse. These theories underpin the analysis of textual and interpretive practices in print and digital publications. Ultimately, this dissertation underscores the mutable nature of contemporary literary developments in Zimbabwe, ii highlighting their profound implications for writers and readers in an era marked by technological advancements and shifting paradigms of literary consumption. , Thesis (PhD) -- Faculty of Humanities, Literary Studies in English, 2024

- Description: This study is concerned with people’s attitudes towards the Communal Areas Management Programme for Indigenous Resources (CAMPFIRE). This study is situated in Kanyemba, a ward in Mbire District, Mashonaland Central, Zimbabwe. CAMPFIRE is a community-based natural resource management programme that aims at empowering local communities to sustainably manage and benefit from wildlife and other natural resources within their confines. This study explores people’s attitudes towards development (and CAMPFIRE as a development programme) and how they perceive, engage with, and contest development. There are two subgroups living in Kanyemba: the Chikunda, which is the majority group, and the Tembo Mvura. Rooted in post-development thinking, this study highlights the nuances and ambiguities in people’s attitudes towards development. The study relies on interviews, participant observation, and archival material. The study has three guiding objectives. Firstly, I set out to explore how the Tembo Mvura and Chikunda community members living in Kanyemba perceive and interact with the CAMPFIRE programme and how their views coincide with or diverge from mainstream development discourse. The study discusses the Tembo Mvura and Chikunda definitions and descriptions of development and the two groups’ perspectives and experiences of the CAMPFIRE programme. While the Tembo Mvura have mostly negative attitudes towards CAMPFIRE, their Chikunda neighbours exude both positive and negative attitudes towards development, projecting a sense of joy and appreciation but also disillusionment with development. Secondly, I highlight how Tembo Mvura and Chikunda actively participate in and challenge the CAMPFIRE project and how these interactions can be interpreted within the framework of post-development theory. As I explore these attitudes, I portray the ambivalence evident in people’s simultaneous desire for and dismissal of development. While the people dismiss some aspects of development, they still want some development, hence the ambivalence. Finally, I explore how the residents of Kanyemba have responded to the limitations of CAMPFIRE, what alternatives to development they propose, and what role cultural, historical, economic, and environmental factors play in shaping the communities’ alternatives to development. The residents of Kanyemba have different historical and cultural backgrounds, and I highlight how these have influenced the different alternatives to development proposed by Tembo Mvura and Chikunda. In this regard, I explore the nuanced critiques of development held by residents of Kanyemba, examining how cultural and historical factors influence their selective engagement with different aspects of the CAMPFIRE initiative. This thesis contributes to post-development thinking by arguing that the ambivalence evident in people’s attitudes towards development in Kanyemba makes dismissing development more complicated than some post-development theorists suggest. The findings of the study show that people’s ambivalence towards development emanates from CAMPFIRE’s approach that strips individuals of agency, stifles their voices, and curtails democratic participation in determining their preferences and how they desire to progress. , Thesis (PhD) -- Faculty of Humanities, Political and International Studies, 2025

In this regard, I explore the nuanced critiques of development held by residents of Kanyemba, examining how cultural and historical factors influence their selective engagement with different aspects of the CAMPFIRE initiative. This thesis contributes to post-development thinking by arguing that the ambivalence evident in people’s attitudes towards development in Kanyemba makes dismissing development more complicated than some post-development theorists suggest. The findings of the study show that people’s ambivalence towards development emanates from CAMPFIRE’s approach that strips individuals of agency, stifles their voices, and curtails democratic participation in determining their preferences and how they desire to progress. , Thesis (PhD) -- Faculty of Humanities, Political and International Studies, 2025

- Description: Walkability is an important research topic in the Global South where many people in urban settlements walk because of transport poverty. University students are a subset of the urban population in Makhanda who experience transport poverty and largely rely on walking to navigate the city. The purpose of this study is to measure and spatially analyse walkability and walking patterns in the student community of Makhanda, South Africa. This study has a specific focus on students who reside in the Rhodes University campus, Central Business District (Central), Sunnyside, and Westhill. These specific areas were chosen because, in terms of student residents, these are the most densely populated residential areas in the city, but are also the epicentre of student activity. This research intends to explore the existing walkability within these four study sites through a visual survey using common measures of walkability, digital mapping as well as student perceptions of walkability. The quantitative data collected through visual surveys, digital mapping and participatory mapping will be spatially analysed using GIS (Geographic Information Systems). Results show that walking is the main mode of transportation and students do not have affordable alternatives to walking. The Rhodes University campus is the most walkable area with Central being the second, Westhill being the third, and Sunnyside being the least walkable area. Sidewalk conditions (sidewalk presence, evenness and maintenance) and pedestrian safety and security (pedestrian crossings, crime, security features, lighting, the presence of people, and pedestrian visibility) were rated as the most important walkability factors. Additionally, the more walkable roads are mainly found within the Rhodes University campus and Sunnyside while the less walkable roads are mainly found within Central. Furthermore, the epicentre of student activity is focused on the Rhodes University campus during the week and as the week progresses, the epicentre shifts along with a shift in activity. The Rhodes University campus and Central are where students spent most of their time because the main amenities that student use are found within these areas. This research offers insights into walkability that can be directly applied to urban planning and policy-making. Planners should focus their resources on improving walkability, particularly in sidewalk conditions and pedestrian safety and security. By applying the findings of this research, planners can create more conducive, safer, and comfortable walking environments. , Thesis (MSc) -- Faculty of Science, Geography, 2025

- Description: This thesis presents observations of medium to large-scale traveling ionospheric disturbances (TIDs) originating from high latitudes, and propagating towards the equator and TIDs originating from the equator with a poleward propagation in the African-European sector during geomagnetically disturbed conditions between 2006 and 2022. 196 TID activities propagating over the African-European sector were observed, of these TID activities, 161 and 33 were observed during geomagnetic storms, and simultaneous occurrence of geomagnetic storms and solar flares, respectively. Total electron content perturbations derived from Global Navigation Satellite Systems (GNSS) observations within a latitude range of 40°S–60°N and longitude ranges of 20°-40°E representing the African-European sector were analysed based on the storm criteria of Dst ≤ -30 nT. The GNSS total electron content (TEC) data were used to obtain the two dimensional (2d) TEC perturbations. The northern hemispheric part of the African sector has limited data coverage which is visualized by a gap around 20°, where there were no data coverage can be observed in the 2d TEC maps. An important result is that large-scale TIDs (LSTIDs) and medium-scale TIDs (MSTIDs) were found to occur predominantly during the main and recovery phases of geomagnetic storms respectively, at least over the African-European sector. During the main phase of storms equatorward LSTID activity was relatively consistent across both hemispheres, with years of solar maximum, between 2013 and 2015, showing higher frequencies of events. Equatorward MSTID activity appeared less frequent overall, particularly in the southern hemisphere (SH), suggesting that equatorward LSTID activity are more prominent during the main phase of geomagnetic storms. Poleward TID activity were more predominant in the recovery phase than the main phase of geomagnetic storms. , Thesis (MSc) -- Faculty of Science, Physics and Electronics, 2025

- Description: Cytochrome P450s are a superfamily of enzymes with over 50 members involved in metabolizing 90% of xenobiotics. Among the these, families 1, 2, and 3 are responsible for approximately 80% of clinical drug metabolism. This study investigates the effect of Afrocentric missense variants on the structural dynamics of CYP2B6. Molecular dynamic simulations reveal that specific variants affect the enzyme’s flexibility and stability, potentially altering catalytic activity and drug binding properties. These findings highlight the importance of considering genetic variants in personalized medicine and drug development. By investigating CYP2B6’s function and structural changes induced by missense variants, this research advances our understanding of the enzyme’s role in drug metabolism. The study utilized computational tools such as GROMACS and AMBER for pre- and post-simulation analysis, with clustering and DSSP used to assess protein structures. Variants I328T, K282R, P428T and R140Q exhibited significant deviations in enzyme dynamics, while other variants caused minor shifts. Overall, the findings provide insight into the relationship between genetic variants and enzyme function, contributing to bioinformatics and molecular modelling approaches in drug discovery. Future studies could explore the structural and fuctional impacts of CYP2B6 bound to substrates such as antimalarials, expanding the investigation to a broader range of missense variants. , Thesis (MSc) -- Faculty of Science, Biochemistry, Microbiology and Bioinformatics, 2025

- Description: How does a classical world emerge from a quantum world? Can this emergence occur without invoking non-unitary processes such as measurements? Recently, an approach that makes use of just a Hilbert space and the associated Hamiltonian to explain the emergence of a classical world has been proposed. To understand this approach, we will require a clear understanding of the nature of measurements in quantum theory and the different interpretations of it. We then progress onto discussions regarding quantum Darwinism and related _elds of knowledge and how they \bypass" the problem of measurement in quantum theory. Then, we discuss how, using the appropriate choice of factorization of a Hilbert space into a system and an environment and using an acceptable basis observable, we can obtain a quasi-classical state of a system. This approach has previously been applied to study one limit (when interactions dominate the Hamiltonian), but we generalize by applying it to the opposite limit (when interactions are minimal) and suggest a method for the general case (when interactions are neither minimal nor dominant). We then look at Hilbert space fundamentalism, which is the idea that a vector in Hilbert space is the fundamental nature of reality. Hilbert space fundamentalism is a generalized application that takes the idea of the emergence of a classical world from a quantum one and applies it to the Universe as a whole. This leads to the question: could Hilbert space fundamentalism be a candidate for the fundamental theory? Before we evaluate Hilbert space fundamentalism as a candidate fundamental theory, we analyze the theory and inquire as to what makes something a fundamental theory. To understand Hilbert space fundamentalism, we see what a model of the world it predicts looks like. This is done by proposing a mapping from a fundamental Hilbert space to emergent space times utilizing entanglement and the aforementioned recently proposed approach that makes use of Hilbert spaces and Hamiltonians to explain the emergence of classical worlds. To determine if Hilbert space fundamentalism could be a fundamental theory, a set of criteria (completeness in all domains, self-contained, and that speci_c theories emerge from it) is noted. We find that Hilbert space fundamentalism, when viewed through these criteria, cannot be the fundamental theory. , Thesis (MSc) -- Faculty of Science, Physics and Electronics, 2025

- Description: Women business leaders are generating a tremendous impact in their markets, industries and communities through innovation, job creation and economic growth. However, their contributions are often lost in the prevailing narrative that women are over-represented among the poorest and most vulnerable entrepreneurs globally. A review of the extant literature has postulated challenges that women entrepreneurs faced several challenges in the ecosystem in which it operates. Women entrepreneurs have access to limited capital as compared to its men counterparts, fewer opportunities to network and build relationships with other entrepreneurs, investors, and mentors, which affects their access to resources and knowledge. Due to the issue of gender-based stereotypes and biases that women entrepreneurs constantly face, they are unable to meet mentors who can provide them with guidance and support to grow their business. These women-specific challenges have become barriers limiting the growth of women entrepreneurs, however insufficient reports highlight how these hindering factors can create opportunities for the growth of women entrepreneurs. Dwelling on the Process theory, the study explored the impact of Ghana’s entrepreneurial ecosystem on women’s entrepreneurial performance with the moderating role of entrepreneurial identity. The study was a cross-sectional quantitative research design with data collected from 413 women entrepreneurs in the Greater Accra Region using structured questionnaire collected using the survey monkey online tool. The data was analyzed using IBM SPSS v.25 and the PLS-SEM v.4.0. The first objective was examined through 12 hypotheses, while the second was analyzed using 2.The study finds that access to finance has positive and insignificant effect on the entrepreneurial performance of women in Ghana. Likewise, education and training have a negative and insignificant effect on the market and operational performance of women entrepreneurs in Ghana. The results of the study postulated that the availability of infrastructure and resources has a negative but significant effect on both the market and operational performance of Ghanaian women entrepreneurs. The results of the study further reported a positive but insignificant impact of network and social capital on the market performance and operational performance of women entrepreneurs in Ghana. The results of the study in relations to the regulatory environment and women entrepreneurial performance indicates an insignificant relationship between regulatory environment and market performance and regulatory performance whilst cultural and social factors within the Ghanaian ecosystem negatively but significantly influence the entrepreneurial performance of women in Ghana but innovation and knowledge spillover have a positive and significant impact on both the market performance and operational performance. Furthermore, the findings of the study suggest that Ghana's entrepreneurial ecosystem may not have a substantial direct impact on women's entrepreneurial performance in Ghana. Further practical and theoretical implications of the study are discussed in the thesis. , Thesis (PhD) -- Faculty of Commerce, Rhodes Business School, 2025

- Description: Ubuntu njengefilosofi yamaAfrika egxile kwindlela yokuziphatha nokuphilisana kumzi oNtsundu kudala yaba yingxoxo kwiinkalo ezahlukileyo ezifana nezopolitiko, ezemfundo, ezolawulo ukubala nje ezimbalwa. Njengoko Ubuntu buyingxoxo ekhula mihla le, kubabhali abafana noW.W. Gqoba, uJ. Solilo kunye noJ.J.R. Jolobe lushokoxekile uncwadi oluphanda ngendlela aba babhali abathe babonakalisa ngayo Ubuntu bekwahlaba ikhwelo ngeendlela zokulondoloza Ubuntu kwiimbalo zabo. Le thisisi iza kushukuxa indlela abathe aba babhali bahlaba ngayo ikhwelo ekubonakaliseni Ubuntu nendlela obunokuthi Ubuntu busetyenziswe ngayo ukuqinisekisa ukuba umzi oNtsundu awubonwa njengalowo ungaphucukanga, ungenakho ukusebenzisa iingcamango zobuntu ukuwuphuhlisa. Uphando luza kugocagoca ezi ncwadi zilandelayo: Umyezo ngokubhalwe nguJ.J.R. Jolobe ; Ilitha (isihobe) ngokubhalwe nguJ.J.R. Jolobe ; Elundini loThukela (iprozi) ngokubhalwe nguJ.J.R. Jolobe ; Isizwe esinembali: Xhosa histories and poetry (1837-1888) ngokubhalwe nguW.W. Gqoba ; Umoya wembongi: Collected Poems (1922-1935) ngokubhalwe nguJ. Solilo Uphando lukhethe ezi ncwadi zikhankanywe apha ngentla kuba zona ziyibalisa ngokucacileyo imbali yamaAfrika. Ezi ncwadi zinembali etyebileyo nezithi zisebenze njengokubhebhetha indlela amakoloniyali athi ayibhala ngayo imbali yamaAfrika eyayijolise ukuwajongela phantsi. Kwakhona olu ncwadi lwabhalwa ngexesha apho kwakukho imingeni ekunikeni inkcazo evakalayo ngokuba kuthetha ukuthini ukuphucuka, nokuba amaAfrika ayezibandakanya njani ukulwa nokuphikisa ingcaciso yendlela yokuphila kwamaAfrika yempi yaseNtshona. Ezi mbalo kungaxoxwa ngelithi, zithi zibe zezo zinike ngcaciso yimbi ngomba wempucuko leyo ingenokoyanyaniswa neengcamangco zaseNtshona. Apha kwezi ncwadi kuza kuhlutywa indlela Ubuntu obuthe baphuhla baze baphinda badodobala ngayo phantsi kolawulo lwempi yaseNtshona. Ekwenzeni oko, umphandi akayibethisanga ngoyaba imbali yoMzantsi Afrika neAfrika nje ngokubanzi, imbali yobukoloniyali. Yile mbali yobukoloniyali ethe yabangela ukuba aba babhali bezi ncwadi eziza kuphicothwa luphando bayithathele kubo ezandleni indima yokuqinisekisa ukuba iingcamango nemimiselo yobuntu yileyo bathi babhale ngayo ngeenjongo zokwenza uluntu lungaphulukani nokuxabisa Ubuntu njengefilosofi. Uphando lubone kubalulekile ukuba lulandele iingcamango zeAfrocentricity nezo zomanyan lwamaAfrika (Pan Africanism) ekubhentsiseni obu buntu bubonakaliswa ngaba babhali. Uphando luchonge ezi thiyori zimbini, eyeAfrocentricity kwakunye neyomanyano lwamaAfrika (Pan Africanism) kuba zombini ezi thiyori zikhokelisa phambili ukuxatyiswa kwamaAfrika njengabantu ekukudala benazo iifilosofi ezijolise ekuphuhliseni umzi oNtsundu. Kubonakele kufanelekile ukuba iphulo lokuphanda ngendlela Ubuntu obubonakaliswe ngayo ngaba babhali lenziwe ukukhumbula imisebenzi emikhulu eyenziwe ngamaqhawe abantu abaNtsundu nabathe banegalelo elikhulu ekuphakanyisweni koncwadi lwemveli kwakunye nenkqubela phambili kwimfundo yabantu abangamaAfrika. Ngokuphandle uncwadi lwaba babhali lubonakele luyinxalenye yobomi babo. Kukwakufumaniseka ukuba babhale bandululwe zizinto ezithe azabaphatha kakuhle ebomini babo zaze ezo zinto zawuphazamisa umoya wabo nentlalo yabo bada baqonda ukuba mababhale, baphokoze oku kuphuphuma kweengcinga zabo ukuthuthuzela kwanokuphilisa abanye abantu abathe badibana neenzima ezinjalo zobomi. Phakathi kwezo meko singabala iimeko zopolitiko zeli lizwe ezithe zabuchaphazela ubomi babo, imeko yezemfundo ethe yabonakala inomkhethe, iinqobo zenkcubeko ekuthe kwaphawuleka ukuba zibethiswe ngoyaba ngabo basemagunyeni de zenza noluntu lungazithatheli ngqalelo. Ezi meko zazibonwa njengezo zingelolutho ekuphuhliseni ubomi boluntu nje ngokubanzi. Oku kunyhashwa kwamalungelo abantu kwakunye neemeko ezimbi abathubeleze kuzo zibe sisizekabani sokwenziwa kolu phando ngobuntu nokuvuselela izazela zoluntu. Ezi mbalo zihlalutyiweyo ziquka nogxekoncomo lwazo zenza kanye le nto ichazwe kuphando, ukudakanca indlela Ubuntu obungasetyenziswa ngayo ukuphuhlisa isizwe esiNtsundu. Ziimbalo ezi ezigqithisa umyalezo neembono zaba bahlali ngokulondolozwa kwenkcubeko igcinwe encwadini njengamabali anika umdla erhwebesha uthando loncwadi kwanobuzwe babafundi abaNtsundu ngokubanzi, ingakumbi abafundi abangamaXhosa kuba babhalele bona ikakhulu. Ngababhali aba ababhale ngesiXhosa esiphakamisa inkcubeko yabo. Okuphawulekayo ngokukodwa kuJolobe yinto yokuba kwinoveli yakhe ethi, Elundini loThukela (1959) ude wasebenzisa iilwimi ezimbini isiHlubi kunye nesiXhosa eziqulethe iinkcubeko zazo. Ukongeza, ekubhaleni ngolwimi lwabo lwenkobe, aba babhali balandela ikhondo nesikhokelo sabantu abafana noMqhayi, noWa Thiong’o abazimvo ngokulondolozwa kolwimi noncwadi zikwasetyenzisiwe ukubonakalisa ukubaluleka kweelwimi zamaAfrika kuncwadi. Ekuhlalutyeni ezi mbalo zikhethiweyo, umphandi ukhethe ukulandela indlela yophando eyikwalitheyithuvu ngokugxininisa kuhlalutyo lomxholo. Isizathu sokuba indlela enjalo ibe iyasetyenziswa kukuba idatha ehlalutyiweyo ivela kwidatha esele yapapashwa, iincwadi ukutsho. Le ndlela yindlela eya kuba sisikhokelo esiphambili somphandi ukuqinisekisa ukuba iinjongo zophando ziyafezekiswa. Uphando lufumanise ukuba aba babhali bakhethiweyo bathe ngokwenene banendima abayenzayo ukuqinisekisa ukuba iziseko zobuntu ziyalondolozwa. Oku kuqala kwimiba engenkcubeko apho kuxoxwe ngelithi, umntu oNtsundu kuyafuneka ukuba angayibethisi ngoyaba into yokuzingca ngobuni bakhe. Kananjalo njengababhali ababe bhala beqwalasela yonke imiba yentlalo, into engokuzilanda ngokobuzwe yinto ebonakala isembindini kwiimbalo zabo njengoko besenza ikhwelo ebantwini abaNtsundu ukuba baze bangayilibali imvelaphi yabo. Kumba wezemfundo ingakumbi uGqoba ubalula ukubaluleka kwemfundo yemveli. Kolu phando kufumaniseke ukuba kwiimbalo zabo ababhali bayilwela ngamandla into yokumanyaniswa kwemfundo yaseNtshona naleyo yemveli yamaAfrika. Oku ingasisakhelo sokuqinisekisa ukuba umntwana womgquba uyafikelela kwimfundo ekwaziyo ukuthetha ngeengxaki ezihlangabezana nabantu abaNtsundu gabalala. , Ubuntu as an African philosophy with its focus on issues of good behavior and welfare of black Africans has forever been an unending debate on various spheres of life: those of politics, education, and governance, to name a few. Even though it is a debate with new avenues daily, there is limited research on the works of W.W. Gqoba, J. Solilo, and J.J.R. Jolobe on how they have argued on ways in which the values of Ubuntu may be preserved. This study is therefore undertaken to investigate exactly how these writers maintained in their writings ways in which Ubuntu can be used to ensure black Africans are not seen as a society that is ‘backward’, a society that cannot use Ubuntu principles for development. The research will examine the following books: Umyezo (poems) by J.J.R. Jolobe ; Ilitha (poems) by J.J.R. Jolobe ; Elundini loThukela (prose) by J.J.R. Jolobe ; Isizwe esinembali: Xhosa histories and poetry (1837-1888) by W.W. Gqoba ; Umoya wembongi: Collected Poems (1922-1935) by J. Solilo. In short, it is argued in the study that the selected texts are fine literary products and that their narratives were created following African history. They form part of negating the negative element that has been created by the accounts of colonial masters, as such an account of history was meant to undermine Africans: rich literature and history. Moreover, they were written at a time when there were challenges associated with civilization: what was meant by it and how Africans related to the idea as per Western standards. These texts, it could be argued, present an alternative on this matter by removing Western thoughts on what really are the elements of cultural civilization. In an in-depth analysis of selected writers’ texts, it was important to examine the ways in which Ubuntu has developed and evolved over the years under the administration of Western powers. In the analysis, the researcher did not turn a blind eye to the colonial history of South Africa and that of Africa in general. In that history, an argument is as follows: the thoughts and values of Ubuntu as captured by these writers are to remind people to appreciate Ubuntu as a philisophy. In my analysis, it was important to use theories such as Afrocentricity and Pan-Africanism in understanding and decoding Ubuntu as depicted in the writings of the selected writers. In choosing these theories, it is due to their main argument emphasizing the value of being African and the fact that Africans have long had their philosophies meant for the betterment of the society. It seemed appropriate to investigate how Ubuntu, as shown by these writers, is recorded to act as a reminder of the great works done by Africans who contributed greatly to the promotion of African literature as well as progress in the education of African people. The literature of these writers should be seen as an integral part of their lives. It is also found that they wrote because of the ills that affected their lives and disturbed their spirit and well-being until they realized that they should write and express their thoughts to comfort and heal other people who have encountered such hardships in life. Among those are the political conditions of this country that have affected their lives, the educational situation that has been shown to be biased, and cultural things that have been noticed to be ignored by those in power as they made the public not pay attention to them. This is because they were seen as having little value in the development of human life in general. That is why this research on Ubuntu could be seen as an initiative aimed precisely at those ideas that can be 'revitalized’ by conscientious people. The analysis of literary texts includes criticism to address the main question in this research: how Ubuntu can be used to develop the Africans. This is the kind of literature that conveys the message and ideas on the preservation of culture as preserved in the books with interesting stories that appeal to the love of literature and the nationalism of Africans in general, especially Xhosa people because they wrote mainly for them. It is these writers who wrote in Xhosa that promote their culture. What is particularly remarkable about Jolobe is the fact that in his novel, Elundini loThukela (1959), he used two languages, isiHlubi and isiXhosa, which contain their own cultures. In addition, in writing in their mother tongue, these writers follow the path and guidance of people like Mqhayi and Wa Thiong'o, whose views on the preservation of language and literature have also been used to show the importance of African languages in literary analysis. In the analysis of these selected texts, I have opted to follow a qualitative research approach with a focus on content analysis. The reason behing such an approach is the fact that the data so analysed is from existing data, books. This approach is one that will be a key guide for the researcher to ensure that the aims of the study are achieved. In this research, it was found that these selected writers really have played to ensure that the fundamental values of Ubuntu are preserved. This starts with non-cultural issues: it has been argued that the Africans should not ignore the pride of their identity. Also, as writers who wrote considering all social issues, the issue of national identity is something that appears at the centre of their writings as they call upon Africans not to forget their origins. In terms of education, Gqoba especially mentions the importance of African traditional education. In this research, it has been found that in their writings, the writers are strongly advocating for the integration of Western education with that of African traditional education. This could be taken as framework to make sure that the African child has access to an education that addresses the problems faced by Africans at large. , Thesis (PhD) -- Faculty of Humanities, Languages and Literatures, 2025

- Description: Ubuntu njengefilosofi yamaAfrika egxile kwindlela yokuziphatha nokuphilisana kumzi oNtsundu kudala yaba yingxoxo kwiinkalo ezahlukileyo ezifana nezopolitiko, ezemfundo, ezolawulo ukubala nje ezimbalwa. Njengoko Ubuntu buyingxoxo ekhula mihla le, kubabhali abafana noW.W. Gqoba, uJ. Solilo kunye noJ.J.R. Jolobe lushokoxekile uncwadi oluphanda ngendlela aba babhali abathe babonakalisa ngayo Ubuntu bekwahlaba ikhwelo ngeendlela zokulondoloza Ubuntu kwiimbalo zabo. Le thisisi iza kushukuxa indlela abathe aba babhali bahlaba ngayo ikhwelo ekubonakaliseni Ubuntu nendlela obunokuthi Ubuntu busetyenziswe ngayo ukuqinisekisa ukuba umzi oNtsundu awubonwa njengalowo ungaphucukanga, ungenakho ukusebenzisa iingcamango zobuntu ukuwuphuhlisa. Uphando luza kugocagoca ezi ncwadi zilandelayo: Umyezo ngokubhalwe nguJ.J.R. Jolobe ; Ilitha (isihobe) ngokubhalwe nguJ.J.R. Jolobe ; Elundini loThukela (iprozi) ngokubhalwe nguJ.J.R. Jolobe ; Isizwe esinembali: Xhosa histories and poetry (1837-1888) ngokubhalwe nguW.W. Gqoba ; Umoya wembongi: Collected Poems (1922-1935) ngokubhalwe nguJ. Solilo Uphando lukhethe ezi ncwadi zikhankanywe apha ngentla kuba zona ziyibalisa ngokucacileyo imbali yamaAfrika. Ezi ncwadi zinembali etyebileyo nezithi zisebenze njengokubhebhetha indlela amakoloniyali athi ayibhala ngayo imbali yamaAfrika eyayijolise ukuwajongela phantsi. Kwakhona olu ncwadi lwabhalwa ngexesha apho kwakukho imingeni ekunikeni inkcazo evakalayo ngokuba kuthetha ukuthini ukuphucuka, nokuba amaAfrika ayezibandakanya njani ukulwa nokuphikisa ingcaciso yendlela yokuphila kwamaAfrika yempi yaseNtshona. Ezi mbalo kungaxoxwa ngelithi, zithi zibe zezo zinike ngcaciso yimbi ngomba wempucuko leyo ingenokoyanyaniswa neengcamangco zaseNtshona. Apha kwezi ncwadi kuza kuhlutywa indlela Ubuntu obuthe baphuhla baze baphinda badodobala ngayo phantsi kolawulo lwempi yaseNtshona. Ekwenzeni oko, umphandi akayibethisanga ngoyaba imbali yoMzantsi Afrika neAfrika nje ngokubanzi, imbali yobukoloniyali. Yile mbali yobukoloniyali ethe yabangela ukuba aba babhali bezi ncwadi eziza kuphicothwa luphando bayithathele kubo ezandleni indima yokuqinisekisa ukuba iingcamango nemimiselo yobuntu yileyo bathi babhale ngayo ngeenjongo zokwenza uluntu lungaphulukani nokuxabisa Ubuntu njengefilosofi. Uphando lubone kubalulekile ukuba lulandele iingcamango zeAfrocentricity nezo zomanyan lwamaAfrika (Pan Africanism) ekubhentsiseni obu buntu bubonakaliswa ngaba babhali. Uphando luchonge ezi thiyori zimbini, eyeAfrocentricity kwakunye neyomanyano lwamaAfrika (Pan Africanism) kuba zombini ezi thiyori zikhokelisa phambili ukuxatyiswa kwamaAfrika njengabantu ekukudala benazo iifilosofi ezijolise ekuphuhliseni umzi oNtsundu. Kubonakele kufanelekile ukuba iphulo lokuphanda ngendlela Ubuntu obubonakaliswe ngayo ngaba babhali lenziwe ukukhumbula imisebenzi emikhulu eyenziwe ngamaqhawe abantu abaNtsundu nabathe banegalelo elikhulu ekuphakanyisweni koncwadi lwemveli kwakunye nenkqubela phambili kwimfundo yabantu abangamaAfrika. Ngokuphandle uncwadi lwaba babhali lubonakele luyinxalenye yobomi babo. Kukwakufumaniseka ukuba babhale bandululwe zizinto ezithe azabaphatha kakuhle ebomini babo zaze ezo zinto zawuphazamisa umoya wabo nentlalo yabo bada baqonda ukuba mababhale, baphokoze oku kuphuphuma kweengcinga zabo ukuthuthuzela kwanokuphilisa abanye abantu abathe badibana neenzima ezinjalo zobomi.

Ezi meko zazibonwa njengezo zingelolutho ekuphuhliseni ubomi boluntu nje ngokubanzi. Oku kunyhashwa kwamalungelo abantu kwakunye neemeko ezimbi abathubeleze kuzo zibe sisizekabani sokwenziwa kolu phando ngobuntu nokuvuselela izazela zoluntu.

Ziimbalo ezi ezigqithisa umyalezo neembono zaba bahlali ngokulondolozwa kwenkcubeko igcinwe encwadini njengamabali anika umdla erhwebesha uthando loncwadi kwanobuzwe babafundi abaNtsundu ngokubanzi, ingakumbi abafundi abangamaXhosa kuba babhalele bona ikakhulu. Ngababhali aba ababhale ngesiXhosa esiphakamisa inkcubeko yabo.

Ekuhlalutyeni ezi mbalo zikhethiweyo, umphandi ukhethe ukulandela indlela yophando eyikwalitheyithuvu ngokugxininisa kuhlalutyo lomxholo.

- Description: Data governance (DG) is a developing field that has garnered significant attention in recent years. DG includes persons accountable for data quality (the stewards), policies and processes related to data collection, management, storage, security, and reporting, regulatory compliance, and the information technology platforms and support that ensure efficient infrastructure. Higher education institutions are increasingly prioritising digital governance as we enter a stringent financial landscape that emphasises performance metrics, objectives, cost reduction, and accountability. Effective DG can help universities manage their institutional data by establishing frameworks, accountabilities, policies, procedures, guidelines and processes that leverage technology tools. In universities, data management issues regarding their information systems are a common problem, leading to erroneous and inconsistent data that hampers the effectiveness of these institutions. Insufficient handling of data content, records administration, quality, care, and governance contributes to these data management challenges. Additionally, previous studies have shown that many universities struggle to derive value from their data assets. This study attempts to bridge the gap by exploring the literature, common standards, comparative frameworks, challenges, and critical success factors pertaining to DG practices. By so doing, it provides a suggested data governance framework (DGF) drawn from the literature which focuses on elements of data governance to meet the objectives of the study. This research adopted a mixed-methods approach with a design science research methodology to gain a deep understanding of the subject area. Data collection involved a DG maturity assessment questionnaire and a focus group with key staff to determine the current level of data governance at Nelson Mandela University. Outputs from the data collections instruments were analysed and provide input to the model and the final DGF. This DGF aims to effectively guide, control, and manage the university’s DG efforts, mitigating risks, promoting effective data trust and management. This can aid universities to work towards ensuring that data is accurate, reliable, and consistent. , Thesis (MPhil) -- Faculty of Engineering, the Built Environment, and Technology, School of Information Technology, 2025
