- Description: Globally, Technical and Vocational Education and Training (TVET) colleges are acknowledged as a crucial resource for achieving sustainable economic growth and development. Third-world countries require skilled workers to meet the demands of a rapidly evolving world regarding technology. TVET is a crucial component of any nation’s educational system, preparing students for success in the labour market. Most developing countries have acknowledged the need to establish TVET institutions to mitigate the shortage of the required manpower. In its quest to meet labour demand across various industries, South Africa introduced TVET in all provinces. This study assessed the opportunities and challenges faced in managing TVET college programmes in alignment with the government’s goal of achieving developed nation status by 2030. A descriptive research methodology helped identify the drawbacks and benefits of managing TVET colleges in Gqeberha, South Africa. The investigator employed desktop research to collect relevant data, drawing on various secondary sources from online scholarly databases. These sources included local government reports, newspaper and online articles, research studies, agency reviews, community reports, international firms’ reports, foreign government publications, research scholars’ findings, and universities and research groups’ materials. Content analysis, a qualitative method, was employed to analyse the emerging themes and patterns. The findings revealed that opportunities in TVET management include emerging technologies, collaborations and international engagements, partnerships with industry, and various support services. However, the findings indicated that TVET colleges in South Africa face challenges such as inadequate funding, lack of infrastructure, misaligned and negative perceptions, shortages of experienced and qualified lecturers and support staff, and poor governance. This study serves as a strong foundation for enhanced knowledge and improved TVET management. The study, which relied on secondary qualitative data, advances the development of an evidence-driven understanding of the state of TVET in South Africa and provides a foundation for future strategic interventions. , Thesis (MPA) -- Faculty of Humanities, School of Governmental and Social Science, 2025

- Description: The purpose of the study was to assess the role of financial reporting in fostering compliance with the Public Finance Management Act (PFMA) in the Eastern Cape Department of Public Works (ECDPW). The PFMA serves as a crucial regulatory framework in ensuring transparency, accountability, and effective financial management in the public sector. Compliance with the PFMA is essential for promoting good governance and preventing financial mismanagement, fraud, and corruption. Financial reporting plays a significant role in facilitating compliance with the PFMA by providing accurate, timely, and reliable information on the financial activities of public entities. The study employed a mixed-methods approach, including qualitative and quantitative techniques. Data was collected through literature review, document analysis, questionnaires and interviews. Through purposive sampling,16 key informants were selected to participate in the study. The study's findings emphasise the value of financial reporting in fostering responsibility, openness, and efficient decision-making in the ECDPW. Most participants agreed that increased compliance with PFMA regulations is largely a result of accurate financial reporting. The study also found that several issues, such as a lack of financial literacy, a lack of funding, and structural flaws, hamper the department's compliance efforts. The study recommends bolstering staff financial literacy initiatives, creating strong internal control systems, and providing adequate funding for financial management systems to address these problems. The department may greatly enhance its financial performance and support good governance by prioritising financial reporting and compliance. , Thesis (MPA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2025

- Description: This study seeks to investigate coloured women’s perceptions of violence and seeks to add to the growing body of work on women and violence in the Northern areas of Port Elizabeth; namely Arcadia, Salt Lake, and Helenvale. In doing so, the study investigates the tactics women use to avoid participation in violence and crime and how they build and maintain resilience to violence. Crime and violence are normalised in the everyday life of residents of the Northern areas. Residents must contend with gangsterism and violence in public and domestic spaces. Violence is also pervasive in the everyday life of the youth. High unemployment rates, crime rates, and historical structural inequality are a few of the contributing factors to the occurrence and persistence of social deviance among the youth in these communities. This study seeks to ethnographically explore the perceptions of women in both domestic and public spaces by emphasizing the female perspective of everyday life within violent communities. The study investigates socio-economic issues such as violence, “broken” family structures, inequality, and poverty, and their contribution to pervasive violence within these communities. It seeks to explore the role that coloured women play in their dysfunctional communities and the tactics used to circumvent violence, especially violence in the form of gangsterism. Existing literature focuses on men and their participation in violence while women and their perceptions of violence fall into the backdrop of these dominant discourses. Therefore, this study attempts to rethink women’s (non-)involvement in violence and address their perceptions and tactics used to foster resilience to violence within their communities. The study also seeks to explore the positionality of women within their communities, and the factors which influence participation in or resilience to violence. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2025

- Description: With the end of apartheid and the beginning of democratic dispensation in 1994, South Africa’s governance model was redesigned to cater for and align with the values of the new democratic South Africa. The country’s governance model was decentralised, thus forming three spheres of government: national, provincial, and local. The Constitution of the Republic of South Africa formulates the three spheres of government that are distinct yet interrelated and mutually connected. Each sphere has its own responsibilities and functions, which it performs autonomously within a decentralised cooperative governance system. The three spheres of government are equally imperative. However, local government is considered the most important sphere of government, given that it is embedded in the communities. This sphere is regarded as the face of government and is responsible for essential service delivery to the communities. Municipalities are charged with managing this important sphere of government in the country. However, South African municipalities are generally viewed as being in a state of crisis. Many municipalities in the country are considered at risk, and some have become completely dysfunctional in that they cannot fulfil their constitutional obligations and mandates as per the constitution. In such a situation where a municipality cannot perform its functions and fulfil its obligations, the provincial government can intervene in that municipality through various instruments, including Section 139 of the Constitution. Given the country's rising number of dysfunctional municipalities, provincial authorities' invocation of Section 139 intervention has become widespread in South Africa. Accordingly, this study sought to investigate the effectiveness of Section 139 interventions in local government using a selected municipality in the Eastern Cape as a case study. The study also sought to examine the roles and functions of the provincial government concerning the implementation of Section 139 interventions. The study employed new institutionalism and decentralisation as a theoretical lens to investigate this phenomenon. It adopted a qualitative research approach and included semi-structured interviews with key research participants with knowledge and experience of Section 139 interventions. The study purposefully engaged 20 participants from a selected local municipality in the Eastern Cape. The selected local municipality has been placed under administration for two consecutive terms by the provincial authorities in accordance with Section 139 interventions. The findings obtained through engagement with selected participants were corroborated with secondary data sources regarding the topic under study. The study notes that implementing Section 139 interventions remains a contested phenomenon in local government. It was found that these interventions have, at most, not been effective in turning around dysfunctional municipalities in South Africa. Specifically, the results indicate that implementing the interventions for two terms has not changed the situation in the municipality; instead, it has caused animosity among different municipal role players, thus further deteriorating the state of the municipality and impeding service delivery. The study notes that the selected municipality faces many challenges, including, among other things, service delivery-related protests, unemployment, poverty, and inequality within the municipality. The study's findings show that service delivery remains constrained in the municipality; however, this state of affairs mirrors the general crisis that local government in South Africa faces. Furthermore, the findings confirm that the lack of adequate human, financial and physical resources has made it complex and problematic for local municipalities (especially the ones in rural areas) to perform and fulfil their constitutional obligation of delivering essential services to local communities. , Thesis (MA) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2025

- Description: This dissertation explores the effectiveness of Public-Private Partnerships as an alternative approach to the development and maintenance of road infrastructure in Eastern Cape Province, specifically focusing on the Eastern Cape Department of Transport. This study considers the limitations of existing funding models and infrastructural development methods. Furthermore, it highlights the regrettable state of backlog in terms of road maintenance and construction activities in the province. Through a qualitative research approach, this study investigates possible advantages and disadvantages related to PPP implementation, assessing how such partnerships might improve the region’s general economic growth along with its service delivery efficiency levels. It takes into account the legal framework that governs PPPs, governance issues connected with them, and risk management associated with these partnerships thus providing a detailed examination regarding their relevance within the Eastern Cape Province. The results indicate that, although PPPs offer an optimistic answer to the infrastructure problems experienced by the Eastern Cape, effective implementation would need considerable modifications to current administrative practices and proper integration with the present legal regulation. This research is significant for the area of public administration since it sheds light on various funding methods that may improve road networks within one of South Africa’s most impoverished regions. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2025

- Description: In 2015, the South African Department of Basic Education (DBE) announced plans to pilot scripted lesson plans (SLPs) aligned with the Comprehensive Sexuality Education (CSE) component of the Life Orientation (LO) curriculum. This initiative aimed to address critical challenges such as learner dropout rates, the spread of the human immunodeficiency virus (HIV), teenage pregnancy, and risky behaviours among learners in both primary and secondary schools. Despite being deemed successful by some individuals and organisations, using CSE in Africa faces many obstacles. The DBE in South Africa equipped district coordinators for HIV and acquired immunodeficiency syndrome (AIDS) to train LO teachers in their respective school districts. Despite being seen as beneficial overall, the use of CSE in Africa and other regions is not without difficulties. The HIV and AIDS district coordinators oversee the successful implementation of CSE lessons by LO teachers and train LO teachers in CSE using the recently created CSE scripted lesson plans (SLPs) from the DBE. However, district and provincial office officials' regular monitoring reports show that CSE courses have either not been implemented at all or only partially been implemented in public schools. It appears that HIV and AIDS district coordinators have not provided enough of the updated CSE curriculum to LO teachers during their training. Therefore, this study aimed to explore the perceptions of HIV and AIDS district coordinators regarding the training and monitoring of the CSE programme implementation in the Eastern Cape Province of South Africa. The study employed exploratory research informed by the interpretivism paradigm and qualitative research methodology. The study used Urie Bronfenbrenner’s ecological systems theory as a theoretical foundation. Fifteen (15) HIV and AIDS district coordinators from Eastern Cape education districts in South Africa were included in the purposeful sample applied for this study. Data was gathered through open-ended questionnaires and subsequently analysed using thematic analysis. The thematic analysis was conducted according to Braun and Clarke's six-step framework (Maguire & Delahunt, 2017). The study's findings indicate that the HIV and AIDS district coordinators possess varying qualifications that are insufficient for effectively training LO teachers on CSE. The inadequate training of these coordinators has resulted in ineffective implementation of CSE. Furthermore, the district coordinators' cultural and personal beliefs, rooted in their diverse cultural and religious backgrounds, impact their approach to teaching and learning strategies. The study also found a lack of monitoring and support from the HIV and AIDS district coordinators. Additionally, the effectiveness of CSE implementation is hampered by differing perceptions of CSE among various stakeholders. The study recommends that HIV and AIDS district coordinators improve their qualifications through further education and professional development. They should pursue relevant academic and professional training in HIV and AIDS and LO to gain the skills and knowledge needed for effective training and coordination. The DBE and curriculum designers should consider the cultural and religious values of HIV and AIDS district coordinators for successful CSE implementation and equip them with effective CSE teaching and learning strategies. Regular monitoring and support should be conducted in districts, particularly in schools implementing CSE. In conclusion, the study emphasises the need for strengthening focused monitoring and supporting CSE implementation by HIV and AIDS district coordinators and provincial office officials. The DBE should also raise community awareness of CSE, targeting all key stakeholders to prevent conflicting messages. , Thesis (PhD) -- Faculty of Education, School of Education, Research and Engagement, 2025

Furthermore, the district coordinators' cultural and personal beliefs, rooted in their diverse cultural and religious backgrounds, impact their approach to teaching and learning strategies. The study also found a lack of monitoring and support from the HIV and AIDS district coordinators. Additionally, the effectiveness of CSE implementation is hampered by differing perceptions of CSE among various stakeholders. The study recommends that HIV and AIDS district coordinators improve their qualifications through further education and professional development. They should pursue relevant academic and professional training in HIV and AIDS and LO to gain the skills and knowledge needed for effective training and coordination. The DBE and curriculum designers should consider the cultural and religious values of HIV and AIDS district coordinators for successful CSE implementation and equip them with effective CSE teaching and learning strategies. Regular monitoring and support should be conducted in districts, particularly in schools implementing CSE. In conclusion, the study emphasises the need for strengthening focused monitoring and supporting CSE implementation by HIV and AIDS district coordinators and provincial office officials. The DBE should also raise community awareness of CSE, targeting all key stakeholders to prevent conflicting messages. , Thesis (PhD) -- Faculty of Education, School of Education, Research and Engagement, 2025

- Description: Students enrolled in first‐year programming modules at higher education institutions often have difficulty in mastering the modules (Van Heerden & Goosen, 2019; Figueiredo & García- Peñalvo, 2024). According to Cao, Seow, Lim, Keoh, Dale, Honeychurch, Tasler & Bremner (2023) despite the implementation of various pedagogical approaches, including blended learning to enhance student performance, many students continue to face difficulties with programming modules. The use of online learning platforms, such as Learning Management Systems (LMSs), to facilitate teaching of, for example, programming modules, necessitates the structuring of course content in such a way that students can easily find and digest the learning material. Furthermore, the learning materials used must accommodate the students' various learning styles to effectively support their learning experiences. This research aimed to determine the effectiveness of using an Information Architecture (IA) explicitly designed for structuring different types of content in online courses, with the goal of supporting students’ diverse learning styles. This research focused on a first-year programming module of the Nelson Mandela University (NMU) Department of Computing Sciences and used Modular Object-Oriented Dynamic Learning Environment (Moodle) as the LMS. This study included a group of first-year programming students, a learning experience (LX)designer (LT-Collab staff member), and the first-year programming lecturer from theNMU Department of Computing Sciences as participants. This study adopted Design Science Research (DSR) as the research methodology and applied the DSR process model to this research. DSR seeks to develop knowledge about how artefacts can and should typically be arranged or built by humans to accomplish desired goals (Hevner et al., 2008). Through the DSR process model, this study used a literature review, a questionnaire, interviews, and Focus Group Discussions (FGDs) to identify the most suitable methods of structuring learning content in LMSs to create an IA that allows the lecturer of a first-year programming module to present learning materials that cater to different learning styles. The results showed that the students preferred to learn programming using learning materials such as videos, exercises, voice-over slides, and lecture notes that enable them to practically engage with the material. To accommodate for different learning styles, the LX designer highlighted the significance of using a universal design while developing online courses. This study made both practical and theoretical research contributions. For the practical component, IA was developed to structure the learning materials of a first-year programming module in the Department of Computing Sciences at NMU in the Moodle LMS. The theoretical contribution was the proposed guidelines for developing an IA for a first-year programming module, specifically for providing learning materials that encourage student engagement and to support students’ diverse learning styles in LMSs. , Thesis (MSc) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2025

- Description: The field of robotics faces a significant challenge in creating adaptable and flexible end-effectors. Soft robotics, specifically soft robotic end-effectors, offer an innovative solution. This study aims to propose guidelines for the design of intelligent soft robotic end-effectors incorporating Fluid Elastomeric Actuators (FEAs). The resulting soft robotic end-effectors could enable manipulators to handle delicate objects without causing damage and could ensure the safety of operators working alongside the manipulators. FEAs, which consist of distinct active and passive sections, respond to fluid pressure to achieve controlled deformation. This research aims to introduce an intelligent soft robotic end-effector that utilises FEAs to enable versatile manipulation. A systematic methodology is employed throughout the study to identify the impact of the design considerations governing the performance of intelligent soft robotic end-effectors. The researcher uses the presented findings to propose guidelines for designing intelligent soft robotic endeffectors using FEAs. The guidelines could enable researchers to make informed design decisions when developing these end-effectors. The use of soft and compliant materials in manufacturing fluid elastomeric actuators makes these end-effectors inherently more adaptive, distinguishing this innovation from conventional end-effector designs. , Thesis (MEng) -- Faculty of Engineering, the Built Environment, and Technology, School of Engineering, 2025

- Description: Low organ donor rates are a concern worldwide, specifically in South Africa, where only 0,2% -0,3 % of the population are registered as organ donors. Organ donation is a medical treatment for end-stage organ failures like the heart, liver, lung, and kidneys. In the exploration to understand the reasons behind low transplantation rates, it is suggested that knowledge on the topic of organ donation and people’s values and belief systems can influence their acceptance or rejection of organ donation practices. Adding to this trail of thought, it is important to recognise that Western schools of thought have influenced how religion, beliefs, and the body are conceptualised. This needs to be examined in the South African context, a country known for great diversity, as cultural differences may cause a variation in opinions, realities, and variances amongst religious and cultural groups (Ortner, 2005:3 and Beyers, 2010:1). The fact of cultural diversity and associated differences in social behaviour and social factors influencing organ donation experience, has created a gap in knowledge on the practice and understanding of organ donation in the South African Catholic context. It is this knowledge gap that this thesis seeks to engage. Existing literature has provided useful insight into organ donation and some of the reasons for low donor rates. However, they do not acknowledge the lived experience of the illness or that the Catholic identity differs from church to church and person to person. For this study, the Catholic denomination and its religious practices were explored to understand the conceptualisations and practices in relation to organ donation. The principles and practices of the Catholic Church allow for differentiation from other Christian denominations. The question of healthcare choices is a central topic in the Catholic Church, and choices may be linked to the Catholic identity. Furthermore, the ‘lived experience’ of the individual must be recognised as it can affect individuals' therapeutic choices. The study adopted a qualitative research and ethnographic approach, through which empirical data was collected during fieldwork through focus group discussions, semi-structured interviews, and observation during the activities of the Catholic mass. Theoretical perspectives were drawn from a social constructivist and hermeneutic lens, recognising that identity construction relates to social interactions and constructing meanings. Self-reflexivity was used as an analytical approach. It was recognised that the individual’s subjective reality or personal experiences can influence their health choice behaviours. Thus, this research study explored the parishioners' subjective experiences and identity construction regarding organ donation. The study showed the complex interconnections between religion, belief, cultural norms, and personal values that influence individuals’ attitudes towards organ donation. These elements contribute to diverse and occasionally conflicting perceptions of organ donation, reflecting the obscure development of identity construction within the religious and cultural contexts of the Catholic community. , Thesis (PhD) -- Faculty of Humanities, School of Governmental and Social Sciences, 2025

- Description: Society is shaped by an array of components, and one of the pivotal components is higher education. The nature of universities and their roles in society compel universities always to strive to respond adequately to their nation-building responsibilities. Notably, administrators play an important role in universities as they make significant contributions to ensure that universities attain their nation-building responsibilities. However, most of the focus in literature is directed toward students and academics in terms of access, throughput, quality, and transformation. There has not been enough attention given to our understanding of the role of administrators, their understanding of quality, and how they contribute to the transformation of universities. This study embarked on understanding administrators’ roles in enhancing the quality of universities within the broader transformation discourse of South Africa’s higher education. The main research question that underpinned the study was ‘How has the role of administrators contributed to the transformation of a South African university?’ This question was further divided into three as follows: 1) How has administrators' understanding of their roles been conceptualised at a South African university? 2) What notions of quality have constructed administrators' understanding of their role at a South African university? 3) What could inform the role of administrators in contributing towards transformation at a South African university? Qualitative research was deemed appropriate for the study, as it provides detailed and in-depth responses from participants, rather than quantitative research. A single case study research methodology was used with a focus on Nelson Mandela University. The study used purposive sampling to select relevant participants, who were administrators at Nelson Mandela University. Data was generated, using semi-structured one-on-one interviews, and policy documents. Thematic analysis was used, and four themes emerged from the data: 1) Policy description of the job and alignment of responsibilities, 2) Administrators’ responses to expected responsibilities, 3) Challenges experienced while executing duties, and 4) Perceived understanding of quality. The study concluded by suggesting several recommendations in areas of policies, quality, and avenues for a better understanding of the role of administrators at universities. , Thesis (MEd) -- Faculty of Education, School of Education Research and Engagement, 2025

- Description: The increasing demand for high-bandwidth applications such as video streaming and cloud computing is driving the evolution of optical networks to manage dynamic traffic patterns more efficiently. Among emerging paradigms, Optical Burst Switching (OBS) over transparent flexi-grid networks shows great promise for optimising resource utilisation compared to traditional Optical Circuit Switching (OCS). However, two key challenges hinder its adoption, namely, high burst loss due to contention in OBS and the heightened susceptibility of flexi-grid systems to optical impairments. Addressing these limitations is critical to harnessing the full potential of these technologies This thesis investigates the application of Ant Colony Optimisation (ACO) algorithms to solve the Routing and Wavelength Assignment (RWA) problem in flexigrid OBS networks. Building on prior work that developed the Flexible Spectrum Ant Colony (FSAC) and Congestion Measure Flexible Spectrum Ant Colony (CMFSAC) algorithms, this study introduces a novel approach: the Usability Metric Flexible Spectrum Ant Colony (UM-FSAC). The UM-FSAC algorithm incorporates a dynamic “Link Usability” metric that evaluates network link quality based on fragmentation and wavelength utilisation, enabling more effective resource allocation. Performance evaluation reveals that UM-FSAC significantly reduces Burst Loss Probability (BLP) compared to earlier algorithms. Additionally, this study provides a holistic analysis of network performance, considering metrics such as fairness and efficiency, to offer deeper insights into the broader impacts of ACO-based RWA strategies. Furthermore, the algorithms are benchmarked against analytical and heuristic lower bounds from the literature, providing a robust assessment of their practical effectiveness under various network conditions. , Thesis (PhD) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2025

- Description: Diabetes mellitus, a global chronic disease, has, during the past decades, continued to rise. In recent years, even though the increment rate has slowed down, it remains a highly important priority for public health. Nanotechnology could greatly enhance the quality of life of individuals diagnosed with diabetes through its applications in management and treatment, including innovative blood sugar monitoring, targeted controlled insulin release, regenerative medicine, and enhanced wound healing. Recent developments in diabetes treatment using nanotechnology have attracted increasing interest due to their potential to improve patient outcomes. Accordingly, the current research aimed to investigate the anti-hyperglycaemic potential of green-manufactured CeO2 nanoparticles using oleanolic acid derived from Syzygium aromaticum methanolic cloves extract. Material and methods: In this study, CeO2 NPs were synthesized using pure oleanolic acid (Oleanolic Acid capped cerium oxide nanoparticles, OA-CeO2 NPs) and methanol clove extracts (Syzygium aromaticum methanolic crude cloves extract capped Cerium oxide nanoparticles, CCE-CeO2 NPs), and the physicochemical features were evaluated by spectrometry, electron microscopy and dynamic light scattering. The effects of CeO2 NPs on cell viability were determined using an MTT assay. The hypoglycaemic potential of CeO2 NPs was investigated using the glucose colourimetric assay on the human liver cancer cell line (HepG2) and mouse myoblast cell line (C2C12). The cells were treated for 0, 24, 48 and 72 hours with different concentrations of CeO2 NPs (1, 25, 50 and 100μg/mL), oleanolic acid (160μg/mL) and cloves crude extracts (160μg/ml) where metformin (160μg/mL) acted as a positive control. Results and Discussion: The average size range of synthesized CeO2 NPs diameter was 173±56 nm, with polydispersity index values of 0.28 and 0.20. The zeta potential of CeO2 NPs varied between - 22.7 mV to -36.8 mV. The CeO2 NPs showed no cytotoxic effects on both the cell lines as the results revealed no significant statistical variations between the treated cells and untreated cells following the MTT assay. Our data demonstrated a pronounced anti-hyperglycaemic effect, with glucose levels significantly decreasing from 21.60 ± 0.10 mmol/L to 5.0 ± 0.84 mmol/L in liver cells treated with OA-CeO2 NPs at the lowest dose (1 μg/mL). Conversely, the highest dose (100 μg/mL) of the CCE-CeO2 NPs significantly decreased glucose concentrations from 21.60 ± 0.10 to 4.90 ± 0.74 mmol/L in the HepG2 cell line. In the mouse myoblast cell line (C2C12), glucose concentrations declined to normal physiological levels of 4.5 -5 mmol/L following treatment at doses of 50 and 100 μg/mL of the OA-CeO2 NPs and at 25 μg/mL dose of the CCE-CeO2 NPs which reveals improved glucose utilization by the cells, as a result of the improved drug bioavailability, permeability, and solubility. The glycogen assay showed that C2C12 and HepG2 cells had an increase in glycogen concentration after administration of CeO2 NPs within the period of 72 hours compared to the negative control which correlate with the increase of glucose uptake by the cells. The green synthesized CeO2 NPs using oleanolic acid lowers glucose concentration in both muscle and liver cell lines without toxic effects on the cells. Furthermore, the CeO2 NPs restored the depleted glycogen following glucose utilization by the cells. These findings may lead to the development of CeO2 NPs synthesized using oleanolic acid for the management of diabetes mellitus with improved pharmaceutical qualities. , Thesis (MSc) -- Faculty of Science, School of Biomolecular & Chemical Sciences, 2025

The glycogen assay showed that C2C12 and HepG2 cells had an increase in glycogen concentration after administration of CeO2 NPs within the period of 72 hours compared to the negative control which correlate with the increase of glucose uptake by the cells. The green synthesized CeO2 NPs using oleanolic acid lowers glucose concentration in both muscle and liver cell lines without toxic effects on the cells. Furthermore, the CeO2 NPs restored the depleted glycogen following glucose utilization by the cells. These findings may lead to the development of CeO2 NPs synthesized using oleanolic acid for the management of diabetes mellitus with improved pharmaceutical qualities. , Thesis (MSc) -- Faculty of Science, School of Biomolecular & Chemical Sciences, 2025

- Description: This study explores the role of arts-based participatory research (ABPR) in fostering inclusive management strategies for the uThukela Marine Protected Area (MPA) in KwaZulu-Natal, South Africa. Acknowledging historical marginalisation of local communities in marine conservation in South Africa and globally, this research used an adaption of the photovoice methodology to assess how Traditional and Local Knowledge Systems (TLKS) of local communities can be incorporated into MPA management. The study was guided by objectives to test participatory research methods, provide a platform for knowledge sharing, and identify potential pathways for meaningful, inclusive MPA governance. The value of incorporating co-researchers rather than participants is evident in the depth and breadth of knowledge shared and incorporated into this research. Findings highlight the socio-cultural significance of the environment to the Nqutshini community for fishing, agriculture, and traditional and cultural heritage and practices. TLKS were found to be vital insights that MPA governance can consider to address conservation while still being respectful of the local communities and their livelihoods. The photovoice method proved to be an effective tool for empowering participants and producing insight recommendations for potential action. Challenges to inclusivity, such as limited consultation and socio-economic barriers, were juxtaposed with opportunities for building equitable partnerships through co-management practices. By using ABPR as a tool for integration and learning, and putting the voices of the community above any others, this research contributes to broader discourse in inclusive conservation in South Africa. The importance of balancing ecological, socio-cultural, and economic factors in MPAs can advance strategies for inclusive and sustainable MPA management. , Thesis (MA) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2025

- Description: Accurate Demand forecasting for many industries including automotive and coatings industry, is a cornerstone of ensuring accurate supply forecasting for supply chain management. This research primary objective is to assess the elements that can be used to improve forecast accuracy in the surface coatings industry. An operational plan that informs resource allocation and product delivery strategy can be delivered accurately when it is informed by accurate demand forecasting. Further, the strategic decision-making of the organisation is directly impacted by the level of accuracy of forecasting as the key performance indicators are linked to forecasting for finance, operations in a formal supply chain that includes purchasing, planning, production and logistics. These elements directly impact profitability and customer satisfaction. The research was conducted using a qualitative design with data collected using a semi-structured interview model within the automotive and coatings industry. Onion metaphor was used to carry research as methodology, while thematic analysis for analysing data to provide conclusive results was practised. The review of literature and research results confirmed that there are methods still to be exploited by the industry to improve accuracy of forecasting. The impact of time horizon, data quality, seasonal fluctuations, experience and expertise of forecasters cannot be ignored as directly impacted the accuracy of forecasting as confirmed by the research and literature with non-use of AI-driven forecasting methods through advanced technologies in data analysis and strategic decision making for forecast improvement contributing to poor forecast accuracy. To address these challenges, the study recommends the use of forecasters that are trained to gain expertise in order to use advanced technologies of AI driven forecasting methods, and with time, gain experience to be able to improve and maintain forecast accuracy. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2025

- Description: This study investigates the challenges encountered by South African fisheries in their pursuit of Blue Economy strategic objectives, focusing on sustainable development, economic resilience, and marine conservation. South Africa’s fisheries sector is integral to the national economy and the livelihoods of coastal communities. However, it faces significant challenges that hinder its contribution to the Blue Economy. Through qualitative analysis in the form of interviews and document analysis, the study identifies key issues, including overfishing, illegal, unreported, and unregulated (IUU) fishing, limited market access, inadequate capacity building, and insufficient community involvement. The study highlights the need for ecosystem-based management practices, enhanced monitoring and enforcement mechanisms, and robust regional cooperation to combat IUU fishing effectively. Furthermore, it underscores the importance of capacity building and community engagement, advocating for initiatives that empower small-scale fishers and promote co-management systems that integrate local knowledge with regulatory oversight. The findings also emphasize improving market access and economic opportunities for fishers through infrastructure development, sustainable certification, and financial support. Recommendations provide a roadmap for achieving a sustainable fisheries sector that aligns with Blue Economy principles, balancing economic growth with environmental protection and social equity. This study contributes to the broader discourse on sustainable fisheries management by offering insights and actionable strategies that policymakers, industry stakeholders, and community leaders can use to address current challenges. Ultimately, the research advocates for a more inclusive, resilient, and sustainable approach to managing South Africa’s marine resources, highlighting a model that could serve as a reference for other nations pursuing Blue Economy objectives. , Thesis (MMM) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2025

- Description: Manufacturing operations have been a key driver of economic growth in both South Africa and Gqeberha for decades. However, the industry’s significant transmission of greenhouse gas and emissions is a focal point for decarbonisation efforts to restrict escalating temperatures. Green supply chain practices have, therefore, emerged as a managerial ideology that assists manufacturing organisations and stakeholders in securing profits by eliminating environmental danger and enabling ecological competence. In this context, the study assessed the impact of green supply chain practices within the manufacturing sector of Gqeberha. This included establishing antecedents and outcomes of green supply chain practice implementation within the Gqeberha manufacturing sector. The study also aimed to fill the research gap and contribute to the existing body of knowledge regarding green supply chain management in the manufacturing sector of Gqeberha. The comprehensive literature review in this study included an overview of the Gqeberha manufacturing sector, theories related to green supply chain management, theoretical perspectives on GSCM and the existing studies that support the hypothesised model of this study. The empirical investigation conducted included an online and hand delivered survey questionnaire. The primary data was statistically examined in five phases: exploratory factor analysis (EFA) to test the validity of the survey; Cronbach’s alpha for reliability testing; descriptive statistics; Pearsons’s product correlation; and regression analysis. The empirical results confirmed that green supply chain management implementation can be measured in terms of two constructs, namely strategic and operational implementation of green supply chain management. Additionally, the results of the study confirmed reverse logistics as an antecedent of both operational and strategic GSCP implementation, while green product design and manufacturing (through three pillars namely green product design, green marketing, and green distribution) was confirmed as an antecedent of strategic GSCM implementation. Furthermore, the study revealed competitive advantage and sustainability as the outcomes of both strategic and operational GSCP implementation. This study makes a notable contribution throughout management and innovative and strategic practices as it provides insightful guidelines for stakeholders to understand implement and sustain GSCP strategies, while the empirical results could also be utilised by managers and organisations as a guide to formulate strategies for sustainability relating to the manufacturing industry. , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Management Sciences, 2025

- Description: This dissertation examines the role of mentorship in shaping the professional development of fourth-year B Ed pre-service mathematics teachers during their School-Based Learning (SBL) placements. Grounded in an expanded version of Hudson’s five-factor mentoring model, the study assesses the quality and impact of mentor-mentee interactions, illuminating how mentorship influences the growth of pre-service teachers. Using an explanatory sequential mixed-methods approach, the study integrates quantitative and qualitative data within a pragmatic framework. Surveys with Likert scales collected quantitative data, while qualitative insights were drawn from open-ended questionnaires, semi-structured interviews, and focus group discussions. Structural Equation Modelling (SEM) was used to analyse the relationship between mentor attributes—such as pedagogical knowledge, feedback, and self-efficacy—and pre-service teachers’ perceptions of mentorship. The thematic analysis further explored mentees’ lived experiences. Findings reveal that mentorship is a reciprocal and dynamic process that has a significant impact on the growth of pre-service teachers. Key themes include developmental scaffolding, collaboration, and the application of theoretical knowledge to practice. Statistical analyses highlight strong correlations between specific mentor qualities (e.g., pedagogical feedback) and mentees’ perceptions of mentorship effectiveness. However, challenges such as inconsistent feedback, limited ICT integration, and varying levels of mentor engagement were identified. To enhance mentorship, the study recommends structured mentor training, greater university oversight, and strengthened mentor-mentee relationships. It also advocates workshops and webinars to equip both mentors and mentees with practical teaching strategies. This research contributes to the field by offering an evidence-based framework for improving school-based mentorship. By addressing existing gaps, it provides actionable strategies to enhance professional development for pre-service teachers, ensuring they are better equipped to meet the demands of the teaching profession in South Africa and beyond. , Thesis (MEd) -- Faculty of Education, School of Education, Research and Engagement, 2025

- Description: Being bicultural refers to the integration of two distinct cultures, often involving the constant juggling of diverse cultural norms, languages, and identities, frequently complicated by asymmetrical power relations. In the context of African youth, biculturalism can present challenges, particularly when shaped by the absence of fathers and divergent cultural expectations. This study therefore explored the experiences of African youths in negotiating and integrating their bicultural identity within their families and communities after reuniting with their absent fathers during adolescence. Using a qualitative, exploratory-descriptive design rooted in phenomenology, the research aimed to develop an understanding of how participants experienced and coped with their dual cultural identities. Participants were recruited through purposive and snowball sampling, and semi-structured telephonic interviews were conducted until the point of data saturation. Thematic analysis was applied to identify key themes. The findings revealed that participants encountered significant challenges in reintegrating with their paternal families, including cultural exclusion, language barriers, and limited emotional support. Despite these difficulties, they employed various coping strategies such as learning about both cultural backgrounds, practicing self-construction, integrating, or separating cultures, and relying on religious or traditional practices. Biculturalism offered benefits like exposure to diverse cultural perspectives and bilingualism but also posed challenges of misidentification and unclear social expectations. Family support, particularly socio-emotional support, was highlighted as critical in navigating these complexities. The study contributes valuable insights into the lived experiences of bicultural African youths, emphasizing the need for effective family communication and emotional support to foster successful cultural integration. The findings shows that successful integration of bicultural identity can be promoted through cultural understanding, addressing language 8 barriers, and fostering bicultural identity development through programs such as language immersion, cultural education, community initiatives, and mentorship. By supporting bicultural youth with emotional and social support, enhanced communication with their families, and through opportunities for cultural integration, families and communities can create more inclusive environments that enable bicultural youth to thrive in both their personal and professional lives. , Thesis (MSW) -- Faculty of Health Sciences, School of Behavioural & Lifestyle Sciences, 2025

- Description: The launch of Operation Phakisa: Ocean Economy in 2014 by the South African Government heightened the focus and interest in the ocean as a catalyst to contribute towards South Africa’s lagging economic growth to reduce the pressing challenges of unemployment, poverty, and unequal participation in South Africa’s mainstream economy, particularly, those from previously disadvantaged groups (Odeku, 2021). Operation Phakisa identified six focus areas: marine transport and manufacturing, offshore oil and gas exploration, aquaculture, small harbour development, ocean governance and protection services, and coastal and marine tourism (Loureiro, Du Plessis, & Findlay, 2022). Each of these focus areas is attached to lead departments. Coastal and marine tourism is attached to the National Department of Tourism. After the oil and gas sector, coastal and marine tourism was identified as one of the fastest-growing ocean economy subsectors. With its potential to create much-needed jobs, promote small, medium and micro enterprise (SMME) participation, and contribute to the broader economy by implementing its nodal strategic approach, the Department of Tourism identified nodal zones to which coastal and marine tourism development projects would be intensely implemented. Port St Johns is one of the nodal zones that the department identified. With its unique, high biodiversity, which is attractive to tourists, Port St Johns has been marred with enormous challenges of unemployment, under-development, and high poverty rates. In addition, it has suffered from challenges of competing interests between development and environmental conservation groups enabled by the Transkein Environmental Conservation Decree 9 of 1992, which prohibits development projects within a one-kilometre radius from high water mark. This has resulted in conflicting views, leading to the demise of development, and further perpetuating socio-economic hardships and disparities. Due to similar challenges and with more actors venturing into the ocean economy space, the South African Government has followed the international practice of introducing a marine spatial planning approach to manage the distribution and allocation of spaces for human activities within and around marine and coastal environments. Marine spatial planning has been praised and promoted as the most suitable instrument to manage dynamic, diverse, and fragile environments such as marine and coastal environments. However, although marine spatial planning is touted as an instrument that promotes a participatory and democratic process, it has the potential to fall into the trap of other planning systems, which are top-down, negating the power imbalances amongst the stakeholders. Additionally, such planning regimes fail to recognise the local-centric and diverse interests, including local communities’ use of the marine and coastal resources in these areas. Thus, the current study developed a proposed conceptual framework to guide the development of place-based marine spatial plans to enhance coastal and marine tourism in Port St Johns. The proposed conceptual framework contains critical elements for marine spatial planning (MSP) planners to consider when developing marine spatial plans. The overarching theoretical approach that guides the framework is ecosystem services. This study employed a qualitative research approach, and interviews were used to obtain study participants’ perspectives. Participants were drawn from the Port St Johns Municipality, civil society organisations, development agencies, tourism forums, traditional leaders, councillors, communal property associations, and environmental agencies. Bringing together the perspectives of this diverse group helped to broaden the researcher’s perspective on Port St Johns’ dynamics regarding its challenges and opportunities. Furthermore, these perspectives enabled the development of the proposed conceptual framework for place-based MSP. Recommendations are made to test the proposed conceptual frameworks in developing place-based MSP in coastal cities such as Port St Johns to identify areas of concern for improvement where necessary. , Thesis (D.Phil) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2025

However, although marine spatial planning is touted as an instrument that promotes a participatory and democratic process, it has the potential to fall into the trap of other planning systems, which are top-down, negating the power imbalances amongst the stakeholders. Additionally, such planning regimes fail to recognise the local-centric and diverse interests, including local communities’ use of the marine and coastal resources in these areas. Thus, the current study developed a proposed conceptual framework to guide the development of place-based marine spatial plans to enhance coastal and marine tourism in Port St Johns. The proposed conceptual framework contains critical elements for marine spatial planning (MSP) planners to consider when developing marine spatial plans. The overarching theoretical approach that guides the framework is ecosystem services. This study employed a qualitative research approach, and interviews were used to obtain study participants’ perspectives. Participants were drawn from the Port St Johns Municipality, civil society organisations, development agencies, tourism forums, traditional leaders, councillors, communal property associations, and environmental agencies. Bringing together the perspectives of this diverse group helped to broaden the researcher’s perspective on Port St Johns’ dynamics regarding its challenges and opportunities. Furthermore, these perspectives enabled the development of the proposed conceptual framework for place-based MSP. Recommendations are made to test the proposed conceptual frameworks in developing place-based MSP in coastal cities such as Port St Johns to identify areas of concern for improvement where necessary. , Thesis (D.Phil) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2025
