- Description: Excerpt from Introduction: My interest in the Zulu royal family intensified as I began to read many stories and have lengthy conversations with members of the Zulu royal family and others, including Dr Maxwell Shamase (University of Zululand), about Zulu history. I was struck by the power and prowess of Princess Mkabayi (1750-1843). The elders were said to be speechless when she spoke. According to Shamase, a common Zulu expression which references Mkabayi’s well-known verbal skill is Umuntu ukhuluma kome umlomo, and translates as [like Mkabayi] the speaker speaks clearly and leaves no room for misunderstandings and misinterpretations. I found her to be a brilliant strategist with a servant heart and one whom history had not given due credit, and I was inspired to bring her story to life by setting it to music. I wanted to explore whether or not the events surrounding Mkabayi led to a change of consciousness among the Zulu nation, and I used this as a theme for my symphonic work about her. The lives of Queen Nandi (King Shaka’s mother) and Princess Mkabayi (King Shaka’s aunt) made for fascinating stories I had been privileged to discover, and I felt they were South African treasures to be elevated and shared with the world. The two works listed above form part of my repertoire based on Zulu royal history which are collectively known as “The Royal Trilogy,” and I have come to think of them as part of a developing “urban classical repertoire”. The Royal Trilogy is a set of three compositions with 33 independent scenes linking historical events and people. It includes the following entitled symphonic works for full orchestra: Nandi iNdlovukazi yezi Ndlovukazi (hereinafter “Queen Nandi”), Inkosazane Mkabayi (hereinafter “Princess Mkabayi”), and iNkosi uShaka: Umbono, Isizwe, Isiphetho - King Shaka: A Vision, A Nation, A Destiny (hereinafter “King Shaka”). Nandi premiered on 22 September 2016 as part of “A Musical Tribute Celebrating 200 Years of the Zulu Monarchy,” and “Mkabayi” premiered on 6 September 2018 under a programme titled “Princess Mkabayi: Celebrating Heritage Month”. Both pieces were performed at the Durban City Hall by the KwaZulu-Natal Philharmonic Orchestra with a mass Zulu choir (combination of the Clermont Community Choir, Prince Mshiyeni Choir, and Thokozani Choral Society) for socio-economic and ethnically diverse audiences. The final work, “King Shaka,” is expected to premiere in 2023. A future adaption of the Royal Trilogy is envisioned as an Afro Fusion Contemporary Ballet. , Thesis (MMus) -- Faculty of Humanities, Music & Musicology, 2023

- Description: “Drive for show, putt for dough”. This controversial adage has been a prominent sentiment in the game of golf for decades. Empirical evidence investigating its robustness through determinant of earnings inquiries have identified that the most valuable measure of performance in golf is in fact putting. However, with the ever-perpetuating state of golf equipment and the technologies thereof, the distance debate in golf has thus gained traction. Recent investigations and evidence into the adage had identified a trend-shift with regards to the value associated with distance achievable and putting ability in golf. Therefore questioning the relevance of the adage in the modern form of the game. In conducting a determinant of earnings inquiry through the engagement of engineering “pure” performance measures as empirically identified, this investigation is aimed at recognising a similar trend in a South African perspective, on the Sunshine Tour. Utilising a generalised least square regression methodology, the analysis identifies how the value of the marginal product as-sociated with both player and non-player explanatory measures influence real earnings on the Sun-shine Tour. This determination is observed through the means of a comprehensive scenario analysis, demonstrating the effect of marginal performance differences to the degree of 1% and 5% increase in performance. A trend was therefore identified in which the value of the marginal product, and growth in real earnings associated to driving distance at the 5% level were in fact greater than the that of putting ability. The results further denote the robustness of the adage and the inherent value associated to putting vs. driving distance at the 1% level. The conclusion to this investigation demonstrates the importance of opportunistic positions player’s put themselves in within tournaments to encourage earnings accumulation. Identified through balanced return on investments for all performance measures to “drive for dough to putt for dough”. , Thesis (MEcon) -- Faculty of Commerce, Economics and Economics History, 2023

- Description: The COVID-19 pandemic has raised concerns regarding its possible adverse income distributive consequences, and its different impact according to socioeconomic subgroups (Furceri et al. 2020). This research measures the impact of COVID-19 on inequality in South Africa. To do this the study uses the National Income Dynamic Study (NIDS) wave 5 (2018) and the National Income Dynamic Study Coronavirus Rapid Mobile (NIDS-CRAM) survey waves 1 – 5 (2020 - 2021) datasets to study income inequality in South Africa prior to and during the COVID-19 pandemic until mid-2021. The factor method developed by Lerman and Yitzhaki’s (1985) is used to identify the overall contribution of the different factor sources to income inequality. Labour income is identified as the largest contributing factor and so labour income inequality is decomposed by income determinants using the regression-based decomposition method proposed by Fields (2003). The analysis reveals that labour income worsened during the periods of strictest COVID lockdown, before returning to pre-pandemic levels of inequality as lockdown was eased. Education is the most important determinant of labour income inequality across all time periods, particularly for White, urban and female participants. Although education remains a driving factor of labour income inequality during the national disaster, its contribution lessens as the economy starts recovering by March 2021. Consequently, the contributions of gender, race, age and region increase during the same period. Identifying whom the inequal impact of pandemic has affected worse offers insight that emphasizes the importance social grant systems to aid bridge the inequality gap associated with COVID-19. , Thesis (MEcon) -- Faculty of Commerce, Economics and Economics History, 2023

- Description: Contextualising my research within the Eastern Cape as a descendant of 1820 settlers, I question the modalities of historical recollection by introducing memory as a viable mode of archival production alongside that of the archive. Through interrogating Eastern Cape archival institutes and employing an autoethnographic approach to my familial archives, I show that archival curation affects the gaps, schisms, and interpretations of archives as much as the ‘unreliability’ of memory. I rely on definitions from Jacques Derrida and literature from Achille Mbembe and Verne Harris, as well as reflexive methodologies, to engage the ways of remembering the past and methods of storytelling. With this undertaking, I expose the aporias within archival processes. This written component is part of broader research that encompasses theoretical study and a practice-based Fine Arts research project culminating in an exhibition that shares themes of memory, archive, trauma, and curatorial and personal heritage management. This research engages in case studies of artworks by Angela Deane and Maureen de Jager to contextualise and position the creative process. , Thesis (MFA) -- Faculty of Humanities, Fine Art, 2023

- Description: My thesis is a collection of micro fiction, flash fiction, fairy tales, vignettes and short stories which explore the tension of being both an insider and an outsider. I have access to different cultures without belonging to any of them: as a child, my family moved from a South African Indian community to a formerly whites-only suburb; as an adult I have lived in South Korea, the United Arab Emirates and Sudan. My prose draws on my life experiences, family legends, neighbourhood gossip, news reports and historical events to question norms and ideas that I may have taken for granted had I been fully inside a single culture. In my thesis I frequently spell words phonetically to mimic how I hear or remember them. I also borrow words from languages I don’t speak. I want the languages I use and mix to corrupt each other, as Raymond Federman put it, in order to better express the voices and contexts of the communities I draw inspiration from. Kuzhali Manickavel’s Things We Found During the Autopsy showed me that culturally rich imagery can be used without interrupting narrative flow with explanations. I am also influenced by the poetic sense of rhythm and melody of Lydia Davis’s minimalist prose, and by Sandra Cisneros’s The House on Mango Street, where each concise short story stands alone but together creates a broad understanding of people and place. Anthologies such as PP/FF, edited by Peter Conners, and My Mother She Killed Me, My Father He Ate Me, edited by Kate Bernheimer, have inspired me to be bold in finding the form that best allows each narrative to be told. , Thesis (MA) -- Faculty of Humanities, School of Languages and Literatures, 2023

A Comparison of Mitochondrial Heat Shock Protein 70 and Hsp70 Escort Protein 1 Orthologues from Trypanosoma brucei and Homo sapiens

- Description: The causative agent of African trypanosomiasis, Trypanosoma brucei (T. brucei), has an expanded retinue of specialized heat shock proteins, which have been identified as crucial to the progression of the disease. These play a central role in disease progression and transmission through their involvement in cell-cycle pathways which bring about cell-cycle arrest and differentiation. Hsp70 proteins are essential for the maintenance of proteostasis in the cell. Mitochondrial Hsp70 (mtHsp70) is a highly conserved molecular chaperone required for both the translocation of nuclear encoded proteins across the two mitochondrial membranes and the subsequent folding of proteins in the matrix. The T. brucei genome encodes three copies of mtHsp70 which are 100% identical. MtHsp70 self-aggregates, a property unique to this isoform, and an Hsp70 escort protein (Hep1) is required to maintain the molecular chaperone in a soluble, functional state. This study aimed to compare the solubilizing interaction of Hep1 from T. brucei and Homo sapiens (H. sapien). The recently introduced Alphafold program was used to analyze the structures of mtHsp70 and Hep1 proteins and allowed observations of structures unavailable to other modelling techniques. The GVFEV motif found in the ATPase domain of mtHsp70s interacted with the linker region, resulting in aggregation, the Alphafold models produced indicated that the replacement of the lysine (K) residue within the KTFEV motif of DnaK (prokaryotic Hsp70) with Glycine (G), may abrogate bond formation between the motif and a region between lobe I and II of the ATPase domain. This may facilitate the aggregation reaction of mtHsp70 orthologues and provides a residue of interest for future studies. Both TbHep1 and HsHep1 reduced the thermal aggregation of TbmtHsp70 and mortalin (H. sapien mtHsp70) respectively, however, TbHep1 was ~ 15 % less effective than HsHep1 at higher concentrations (4 uM). TbHep1 itself appeared to be aggregation-prone when under conditions of thermal stress, Alphafold models suggest this may be due to an N-terminal α- helical structure not present in HsHep1. These results indicate that TbHep1 is functionally similar to HsHep1, however, the orthologue may operate in a unique manner which requires further investigation. , Thesis (MSc) -- Faculty of Science, Biotechnology Innovation Centre, 2023

These results indicate that TbHep1 is functionally similar to HsHep1, however, the orthologue may operate in a unique manner which requires further investigation. , Thesis (MSc) -- Faculty of Science, Biotechnology Innovation Centre, 2023

- Description: Diabetes mellitus (DM) is a group of endocrine and metabolic disorders characterised and identified by the presence of hyperglycaemia over a long period and, to an extent, accompanied by hyperlipidaemia. CVD has been reported to be the leading cause of mortality in patients with DM. Several antidiabetic agents are available for managing DM, but these agents are not for curative therapy and present with undesirable side effects. In addition, these agents become less effective as the patient's condition progresses to complete beta-cell failure. Therefore, developing newer antidiabetic agents with minimal undesirable side effects, prolonged efficacy and protection against the development of DM complications are necessary. This study was conducted to identify potential novel antidiabetic agents with cardiovascular-protective activity. The compounds of interest for the study were quinolone derivatives since quinolones have been reported to have an antihyperglycaemic effect. , Thesis (MSc) -- Faculty of Pharmacy, 2023

- Description: Human movements globally have resulted in dispersal and introduction of terrestrial and marine organisms into areas outside of their native range. Species that have been introduced to new habitats can either be alien (not causing any harm to the new environment) or invasive alien species (destroying or competing with the indigenous species for resources). Investigating the source of these introductions is important as it provides baseline information about their biology and evolution. It also allows for better prevention measures for future invasions and for effective conservation strategies. In this study, I investigate the source of the introduced populations of tropical house geckos Hemidactylus mabouia in the Eastern Cape Province using two mitochondrial gene regions, ribosomal 16S and NADH dehydrogenase subunit 4 (ND4). We also look at the potential spread of these species using species distribution models (SDMs). The phylogeny showed that the introduced populations into the Eastern Cape were genetically similar to both H. mabouia lineages found in Central & Southern Africa. The phylogeny produced two clades from which the majority of the introduced samples were grouped in a clade with samples from Angola, DRC, and Mozambique, and only a few nested within the second clade with the South African native population. Haplotype networks from both genes also showed two clades, matching those found in the phylogeny. The introduced samples were associated with samples from Angola and those from South Africa (native) as these localities had a number of shared haplotypes. SDMs showed less evidence that these individuals could naturally move west down the coast as the probability of occurrence was below 0.4 from the Eastern Cape to the Western Cape. Our conclusion was that the introductions may be due to multiple avenues like species moving down the east coast or human translocation including trade routes. From this we can conclude that geckos are largely translocated through human movement as they are known for their opportunistic behaviours as they are commensal with humans. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2023

- Description: This thesis is intended to provide clarity regarding the proprietary consequences of foreign marriages in the context of estate planning and succession in South Africa. It includes an exploration into the impact of specific legislation on foreign marriages, the implications of matrimonial property regimes on a deceased estate in South Africa, private international law principles affecting matrimonial property and succession claims, the scope of antenuptial contracts and postnuptial contracts as existing remedies for foreign remedies, and the harmonisation of succession and matrimonial property law in the European Union (EU). It furthermore suggests potential reforms for the overhaul of the lex domicilii matrimonii principle and associated issues arising therefrom. Various specific issues discussed include the waiver of accrual claims, maintenance claims by surviving spouses of a foreign marriage, choice-of-law rules for matrimonial property rights and succession rights, the registration of a domestic or foreign antenuptial contract for foreign marriages, the formal validity and proper law of antenuptial contracts, the operation of the immutability principle on a domestic and international level, and the common-law approach to the recognition of postnuptial contracts and spousal donations. , Thesis (LLM) -- Faculty of Law, Law, 2023

It follows, logically, that engaging stakeholders in all the three spheres of government and allowing them to fully participate in IGR processes has the potential to play a central role in improving infrastructure sector. Without effective and efficient implementation of IGR in the South African public sector, the transformation of the infrastructure sector will continue to menace many local government departments. Given the critics levelled against the processes involved in IGR, the qualitative and method was used as an investigative method to gain a deeper understanding of IGR cluster systems and its general contribution on infrastructural development. The findings showed a general consensus on the importance of the concept of IGR and its potential in ensuring that stakeholders come up with efficient ways to improve the infrastructure sector. Evidence also showed that the main components of infrastructure such as electricity, housing, water and sanitation and roads are still facing challenges and there are backlogs despite the efforts by all the three spheres of government to ensure that the collaborate in improving the sector. This knowledge allows the adoption of a bottom-up approach to IGR cluster system in the South African local government sector. , Thesis (MPA) -- Faculty of Management and Commerce, 2022

- Description: Background: Maternal and child mortality remain a global health problem, regardless of preventative measures put in place. Antenatal care is crucial to decrease maternal and child morbidity and mortality. However, in Bloemfontein, the sub-district of Mangaung Metro in the Free State, it has been identified that women utilise this kind of service sub-optimally. The study aimed to explore and describe barriers to the utilisation of antenatal care by pregnant women in the Bloemfontein sub-district of Mangaung Metro. Methodology: This study was qualitative and used an explorative, descriptive design. Qualitative data was collected by using focus group discussions and key informants’ interviews. Three focus group discussions with twenty-five pregnant and lactating mothers, aged between 18 and 49 years, were conducted. Participants took part in one focus group discussion at each healthcare facility. Four key informant interviews were conducted with four facility managers and one professional midwife who conducted ANC at the clinic at the time of the study in the three healthcare facilities. A thematic analysis process was used to analyse the collected qualitative data under each identified barrier. The STATA version 15 was used in the analysis of the demographic characteristics of the participants. Results: Most of the participants indicated that they are aware of the importance of attending ANC appointments however, they have voiced that the delayed waiting times and staff attitudes contribute to how they feel about visiting a clinic early. Some of the participants mentioned that they have cultural barriers as they still believe that a traditional pregnant woman should not reveal her pregnancy in the early days but must rather wait until her stomach has grown significantly for her to visit the clinic. Two participants indicated that they had unplanned pregnancies and wanted to do an abortion, but their religious beliefs prevented them to choose to terminate their pregnancies. Economically, not all participants complained about their financial situation though the majority were unemployed and single. Participants from the Bloemspruit facility complained of transport as they stay far from the clinic and they are sometimes forced to walk alone which makes it difficult to attend all their booked sessions with their midwives. The results of the study revealed that there are several factors contributing to late antenatal care attendance namely provider and personal factors contributing to late antenatal care attendance in the Bloemfontein sub-district of Mangaung Metro. Personal factors that were found to be contributing to late antenatal care booking were lack of transport, especially for Bloemspruit participants, unwanted pregnancy, lack of financial support, lack of partner support, cultural and religious beliefs, and lack of knowledge. Provider factors that were found to be contributing to late booking were lack of resources like tools of the trade, long waiting times, poor infrastructure, human resources, and midwives’ attitudes. Recommendations. To deploy qualified midwives to conduct antenatal care clinics, to extend the service over the weekends as participants mentioned that they struggle to get time off from work during the week. Health promotion and community awareness campaigns on the importance of antenatal care may increase the utilisation of antenatal care services. , Thesis (MPA) -- Faculty of Health Sciences, 2023

- Description: The current study was aimed at evaluating the reliability and efficacy of selected remote sensing band ratios and indices in accurately estimating the spatial patterns of suspended sediment concentration level in Umzimvubu Estuary, Eastern Cape, South Africa. Sentinel-2 imagery was acquired on the 29th of March 2022. Band reflectance values were extracted from Sentinel -2 imagery, and laboratory measurements of suspended sediment concentration were obtained from samples collected from fifty (50) sampling points in the estuary on the 29th of March 2022. Sentinel-2 imagery was then validated with the field data in estimating and mapping the suspended sediment concentration. Several remote sensing band ratios Red/(Green plus Near-Infrared), Near-Infrared/Green, Red plus Near-Infrared/Green, Blue(Green plus Red)/Blue and Green plus Near-Infrared)/Blue and indices, that is the Normalised Difference Turbidity Index (NDTI), Normalized Difference Suspended Sediment Index (NDSSI) and Normalized Suspended Material Index (NSMI)) were then used to predict the suspended sediment concentration from Sentinel-2 imagery. The accuracy of band ratios and indices was evaluated by correlating the prediction against the observed suspended sediment concentration from Sentinel-2 imagery. A total of 50 points were randomly surveyed in the Umzimvubu estuary for analyzing suspended sediment concentration. Results indicate that the Blue (Green plus Red)/Blue, the Green plus Near-Infrared)/Blue and NMSI performed well based on their R-squared. The Blue (Green plus Red)/Blue and Green + Near-Infrared)/Blue band ratios had 0.86 and 0, 94, respectively. While NSMI yielded an R-squared of 0,76 and RMSE of 19,2 mg/L. The results in the current study indicate that Sentinel-2 imagery can reliably estimate the concentration of suspended sediment level in the Umzimvubu Estuary using band ratios and indices. , Thesis (MSc) -- Faculty of Science and Agriculture, 2022

- Description: Entrepreneurship plays an important role in societies around the world because it supports economic growth and creates job opportunities. This study investigated the nature of entrepreneurship in three distinct parts of Sakhisizwe Local Municipality, including a town within Sakhisizwe’s former homeland area, rural communities within its former homeland area, and a town within an area characterised by large-scale commercial farms. The study sought to establish the share of adults in the different parts of the municipality involved in entrepreneurship, to identify factors that contribute to the decision to become an entrepreneur, and to examine strategies pursued by, and challenges experienced, different types of entrepreneurs. The study involved a random sample of 362 respondents and both quantitative and qualitative data analysis. Among the main findings is that the proportion of adults involved in enterprise in Sakhisizwe is higher than found by other studies for South Africa as a whole, but is especially high for those living in the town in the former homeland area. While those residing in rural communities also engage in enterprise, they are generally compelled to practice their enterprises in town, thus have the disadvantage of needing frequent transport. While residing in the town in the commercial farming area is not disadvantageous in the same way, the challenge is that the town itself is able to support relatively few entrepreneurs due to fewer people coming to town for their shopping. , Thesis (MSci) -- Faculty of Science and Agricultures, 2022

- Description: The healthcare industry is realising the value of providing ordinary individuals with their personal health data for self-care and self-management purposes, however, these individuals are faced with the challenge of going through, understanding and extracting insights from large volumes of complex personal health data. A dashboard (coupled with data visualization) is regarded as a suitable way to present personal health data effectively, to inform self-care and self- management-based decisions. However, there is no homogeneous (i.e. “one-size-fits-all”) approach to designing dashboards; therefore, this research aimed at creating a set of design guidelines that can be used as a foundation for tailoring dashboards that support the presentation of personal health data. The Design Science Research methodology was used to systematically develop and evaluate the set of dashboard design guidelines. Within this methodology, literature was reviewed and focus groups with participants were conducted to extract insights and inform the development of the initial set (proposed) design guidelines. The proposed design guidelines were then used to develop a medium-fidelity personal health dashboard prototype. Usability testing with the dashboard prototype was conducted to evaluate the efficacy and utility of these design guidelines. The evaluation provided insights that strengthened the quality of the design guidelines. The evaluation indicated that the proposed set of guidelines are suitable for designing a dashboard that presents personal health data effectively. These design guidelines can be adapted in order to inform the process of tailoring dashboards for accommodating different personal health data presentation needs. , Thesis (MCOM) -- Faculty of Commerce, Information Systems, 2023

Nevertheless, this study traced the history of Zimbabwean polarization to the pre-colonial and colonial periods to ascertain the reality of post-independence polarization. The postindependence of Zimbabwe under the Mugabe and Mnangagwa administrations, the ZANU-PF ruling party, was marked by political repression and restriction in electoral politics -a stealth authoritarian practice. In line with earlier studies, this research suggested that Zimbabwe is far from being an institutionalized democracy, given the dearth of electoral democratic qualities, the rule of law- and constitutional subversion. Zimbabwe has had a series of elections under monitoring and evaluation by local and international observers. The electoral observers’ reports and verdicts remain crucial in any given election and require scrutiny to determine their credibility and legitimacy. In 2018, Mnangagwa opened a doorway for international electoral monitoring/observation, previously closed by Mugabe in 2002. While recognizing Mnangagwa’s democratic aspirations, the 2017 post-coup was laced with political repression and 2018 post-election judicial verdict bias. There have been democratic transitioning impediments due to the ZANU-PF party’s centralized state institutions and militarized state capture –typical of a bureaucratic authoritarian regime. With the ZANU-PF party’s competitive authoritarianism in Zimbabwe, the thesis presented the prospects of the Citizens Coalition for Change opposition political parties’ -office seeking coalition building -aiming at maximizing electoral outcomes towards power changing and electoral reforms. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2022

- Description: Globally people are growing older, and nearly every country is experiencing an increase in their ageing populace. In 1960 older people made up 5 % of the world population, while in 2018, they were about 9% of the overall population. Projections are that in 2050 people over the age of 65 will make up 16% of the overall population. To respond to an ageing population, a government must ensure that its policy framework can respond to the needs of its citizens. A society that supports a positive ageing environment improves older people’s well-being. In our complex society, each person is dependent on others in various ways, and social, emotional and practical interdependence is a feature of the human social condition. This means that older people do not function well in isolation but need support for positive ageing. This research project focused on older people’s perceptions of services that support their positive ageing in the Khayelitsha and Gugulethu districts of the Western Cape, South Africa. The theoretical framework employed in the study is Systems Theory. The research approach utilised in the study is qualitative with an explorative and descriptive research design. A non-probability purposive, criterion-based sampling technique was employed. The researcher recruited eleven older persons aged sixty years and above in the Khayelitsha and Gugulethu areas. An NGO that works with older persons’ served as gatekeepers. Semi-structured telephonic interviews were conducted. The data collected was analysed using thematic data analysis. The trustworthiness of the research process was enhanced using Guba’s model. Ethical principles as set out in the Belmont report were also adhered to. The key findings of the current study indicated that in Khayelitsha and Gugulethu areas, there are available services that support positive ageing, such as clubs, excursions and social grants. Environmental aspects challenging positive ageing included unfavourable home conditions such as financial burden and ill-treatment, poverty and unemployment, health problems, and COVID-19 effects. Older people mentioned that there are available but inadequate services such as municipal services and care facilities. Thus, they recommended that there should be poverty alleviation schemes, community development projects such as crafting, gardening, sewing, and more institutions and home-based care for older people. , Thesis (MA) -- Faculty of Health Sciences, 2022

- Description: This study aimed to explore the perceptions of stakeholders in schools regarding the implementation of school sport policy and its impact on school sport development in the Amathole-west district of the Eastern Cape, South Africa. The research sought to examine teachers' knowledge of the Department of Basic Education's school sport policy, assess whether the policy promotes school sport development, identify ways to enhance its implementation in Amathole-west, and propose strategies for the effective implementation of the policy by the Department of Basic Education. Adopting a qualitative interpretivist research approach, the study employed in-depth one-on-one interviews, focus group discussions, and document analysis. A purposive sample of 20 participants was selected, grouped into four focus groups, to contribute valuable insights to the study. Drawing on the Participatory School Governance model and the Social Ecological Model, the findings revealed that teachers, members of the School Management Team, and School Governing Body members perceive sports as essential for learners, as they promote physical health and instill discipline and moral behavior. However, the study also highlighted that teachers and School Governing Body members play a limited role in the implementation of school sport policy and development. Instead, they tend to rely on externally qualified sports experts, resulting in reduced involvement in policy implementation. The study emphasizes the need for improved involvement and investment in school sport policy implementation. Additionally, several strategies were suggested to ensure the effective implementation of school sport policy. These include providing Continued Professional Development (CPD) opportunities for teachers and increasing awareness about the sports policy. In conclusion, this study sheds light on the perceptions of school stakeholders regarding the implementation of school sport policy and the development of school sports in Amathole-west, South Africa. The findings underscore the importance of enhancing teachers' involvement and knowledge in policy implementation and recommend strategies for the successful implementation of the school sport policy , Thesis (MPH) -- Faculty of Health Sciences, 2022

- Description: Riparian vegetation plays several roles in ecological functioning, such as improving water quality because it can filtrate the sediments and provides stability on the floodplain. The condition of riparian vegetation can serve to provide information regarding river condition. The main purpose of this study was to investigate the extent to which water quality level of the Keiskamma River can be explained by the riparian vegetation density patterns. This study used Sentinel-2 Multi-Spectral Instrument (MSI) satellite image to assess spatial patterns in riparian vegetation condition. The Normalized Difference Vegetation Index (NDVI) was generated from the Sentinel-2 imagery and was used as the base from which riparian vegetation density classes were obtained through the supervised image classification technique. The image classification accuracy assessment was caried out to verify and validate the accuracy of riparian vegetation density classes. This technique produced the overall accuracy (OA) classification of 83.72 percent. The riverine water quality parameters were measured on the randomly surveyed sites using the Premium Series PC60 5-in-1 Water Quality Tester. High density of riparian vegetation were found in the upper course of the river. The low-density riparian vegetation dominates the middle course of the river while the lower part of the river contains a mixture of the three riparian vegetation conditions. The one-sample t-test statistical technique was carried out to determine the spatial pattern of water quality parameters. The t-test results revealed the significant variation in water pH, with the p-value of 0.00. However, t-test results also showed insignificant variations in water Total Dissolved Solids (TDS) and electrical conductivity (EC), with p-values of 0.117 0.059 and 0.059 respectively. The linear regression was used to determine the relationship between riparian vegetation and water quality. In this case, the NDVI values were used as surrogate for riparian vegetation condition. The results showed insignificant relationships between NDVI and water pH (r2 = 0.00), NDVI and water TDS (r2 = 0.09), and NDVI and water EC (r2 = 0.09) along the Keiskamma River. In view of the findings obtained from this study “spatial differences in riparian vegetation along the lateral and longitudinal dimensions of the Keiskamma River denote spatial variations in water quality levels”, is rejected. , Thesis (MSci) -- Faculty of Science and Agriculture, 2022
