- Description: In contemporary South Africa, a country in transition, destruction rather than reconstruction seems commonplace. Electricity supply is at an all-time low and ‘load shedding’ is an almost daily occurrence. Similarly, more fragility of water delivery and sanitation service is being reported with the likelihood of ‘water shedding’ a soon-to-be reality. In view of the ever-increasing reported mismanagement of South Africa’s water and sanitation infrastructure, which is likely nearing the point of collapse if not already collapsed, this thesis set out to interrogate at a provincial and municipal level the status of water and sanitation in Chris Hani District Municipality (CHDM), Eastern Cape Province. One major driver behind this study was to evaluate provincial and municipal water/wastewater infrastructure as a platform to support implementation of locally developed bioprocess technologies. First, publicly available historical data was used to derive a baseline or benchmark from which to determine gains/losses in compliance, water quality and efficiency. The period 2009-2013/4 during which Blue and Green Drop reporting was routine, was used as an appropriate start point. Data thus derived indicated that, at provincial and district municipality (DM) level, potable water supply was by bulk water schemes and, sanitation was typically by waste stabilization pond (WSP) treatment of municipal sewage. The derived benchmark for the period 2009-2013/14 indicated that most plants were not compliant (~75% of the Eastern Cape Province water treatment plants (WTP) operating between average performance to critical state), operated either at- or above design capacity (Eastern Cape Province, 16%; CHDM, 19%). A large number of plants for the province (62.4%) and district (81.25%) had hydraulic design capacity or average daily flows that were unknown (information not provided in available literature or plant reports) and final effluent did not always meet the general standard (70.3% of the CHDM wastewater treatment works (WWTW)). To determine the contemporary state (2020 - 2022) of water and sanitation within CHDM, a scoping exercise of WTP and WWTW in selected local municipalities was carried out. This was done along a west-east transect by appraising WTP and WWTW in the towns of Cradock, Tarkastad, Komani, Tsomo, Cacadu, and Ngcobo. Furthermore, targeted assessment of the Queenstown WTP and the Cradock WWTW was used to derive real-time data on the status of water and sanitation infrastructure. Results showed that water and sanitation services within CHDM had, in the years between 2009-2013/14 to date, deteriorated. Freshwater demand significantly exceeded capability of water supply schemes, where demand was as much as three times greater than reported available supply. For most WWTW, operation was in excess of capacity and between 1.52 and 12 times installed hydraulic loading. The targeted scoping exercise revealed that Queenstown WTP is a moderate risk plant (Cumulative risk rating, CRR = 11 and maximum risk rating, MRR = 47.8%), whereas Cradock WWTW was in working condition but with challenges and some infrastructural dysfunction. Assessment of water/effluent quality revealed that turbidity and TOC were above SANS 241 general limit. Non-compliance in terms of nitrate/nitrite-N, ammonium-N, phosphate-P, TSS, total coliforms, E. Coli, and free chlorine was evident at Cradock WWTW. Unstructured interviews with plant operators corroborated these findings. The overwhelming support for bulk schemes for potable water provision and WSP for sanitation indicated a partially water secure municipal district but derelict in terms of its sanitation services. The later, it was concluded, in particular provides an ideal opportunity for implementation of platform technologies to support bioprocesses for entrepreneurship, employment, economic benefit and to secure a closed circular economy for regional water and sanitation through valorisation of co-product streams. Among the co-product streams considered in this thesis are biomass, biogas, biofertilizers, biofuels and several high value chemical products. , Thesis (MSc) -- Faculty of Science, Institute for Environmental Biotechnology, 2022

- Description: Implanon NXT also referred to as subdermal Implant, is a long-acting subdermal contraceptive method available in the South African public health care system since 2014. The implant was introduced to broaden the choice for women of childbearing age to delay or prevent unwanted pregnancies. Following a surge in popularity, reports of early removals and frequent adverse effects led to a significant decrease in its uptake in the country. Insufficient knowledge on Implanon, poor management of side effects, poor counseling by health care workers, and lack of partner support were the main themes that were picked from the interview, influencing uptake or early removals of the Implanon. The major concerning side effect reported was uncontrolled and irregular heavy bleeding The purpose of the study was to explore the factors associated with low uptake and early removals of Implanon NXT among women of reproductive age in one district in Limpopo province. A qualitative research design was used, primarily as exploratory and descriptive in nature. Participants were identified using non-probable, purposeful voluntary sampling. Data collection was achieved using open-ended structured interviews with sixteen (16) women aged from18-49. Data was analysed using thematic method of organizing data into categories, followed by coding and sorting the data to identify patterns and interpret the meanings and responses. An independent consultant was involved to confirm the thematic areas identified after which consensus discussions took place to finalize the analysed data. From the results, it appeared that there was a need that Implanon should be marketed by use of digital platforms and print media for information sharing. These platforms should be utilized by DOH from the National, provincial, district, facility and community levels. There should be clear protocol on how to manage different kinds of side effects, and this information should be rolled out to the implementation level. Health Care workers should provide client education and counselling services to the clients about the effectiveness of the method. Male partner involvement is crucial to provide support for women on contraceptives and to support their contraceptive choices. Mentorship will help providers to attain their proficiency in Implanon counselling, insertions, and removals. Lastly, availing adequate and effective youth-friendly services to enable young people to open up more about challenges and options that can be explored. For the adolescents and youth, these services should be provided by trained providers not at the general unit, where there is a mixture of adult population and the elderly, but at youth zones to enhance the uptake of Implanon NXT. Recommendations are for clinical practice area, for generic student education as well as for further research. The conclusions confirm that the government need to revitalise the Implanon program, to drive the uptake and reduce early removals. Training of health workers and mentorship should emphasize more comprehensive counselling, provide adequate information on what is to be expected and more importantly, how to treat and manage the side effects. That early removals due to side effects become the last option as information need to be widely available to all users utilising the traditional methods and modern methods such as digital platforms to spread the correct information and create demand for the Implanon. The functional service-provision-based youth-friendly services which will cater for the needs of young women and adolescents is highlighted as it provides a comfortable and conducive environment to provide and receive a comprehensive sexual reproductive health and rights services. , Thesis (MPH) -- Faculty of Health Sciences, 2021

- Description: This study presents the synthesis, spectroscopic, photophysical and theoretical characterisation of metal-free (H2TPrOPhOPc), cobalt (CoTPrOPhOPc) and manganese (MnTPrOPhOPc) tetra 4-(4-propargyloxy) phenoxy phthalocyanines. Thermal analysis using thermogravimetric analysis (TGA) confirmed the excellent thermal stability of synthesized tetra 4-(4- propargyloxy) phenoxy phthalocyanines. The metal complexes, CoTPrOPhOPc and MnTPrOPhOPc, exhibited better thermal stability when compared to H2TPrOPhOPc. The residual percentage weight remaining was approximately 70% for CoTPrOPhOPc and MnTPrOPhOPc and 45% for H2TPrOPhOPc after 600°C, clearly confirming the stability of the metal complexes. The MTPrOPhOPcs (where M = H2, Co and Mn) complexes exhibited excellent nonlinear optical properties with strong reverse saturable absorption (RSA), especially when 560 nm excitation laser was used. Their nonlinear optical properties followed this trend: H2TPrOPhOPc > CoTPrOPhOPc > MnTPrOPhOPc. According to the trend observed, the H2TPrOPhOPc was an excellent nonlinear optical limiter when compared to the CoTPrOPhOPc and MnTPrOPhOPc. All the investigated complexes exhibited optical limiting properties comparable to the phthalocyanine complexes reported in the literature. The MTPrOPhOPc complexes were further studied for their electrocatalytic and electroanalytical properties towards the detection of hydrogen peroxide. For the electrocatalytic studies, the synthesized complexes were immobilized onto gold electrode surfaces pre-functionalized with phenylazide (Au-PAz) monolayer. Copper (I) catalyzed alkynyl-azide cycloaddition reaction was used to covalently immobilize the MTPrOPhOPcs onto the gold electrode surfaces to form Au-PAz-MTPrOPhOPc. The MTPrOPhOPcs modified gold surfaces (Au-PAz-MTPrOPhOPc) exhibited good reproducibility and stability in various electrolyte conditions. Electrochemical and surface characterisation of the functionalised gold electrode surfaces confirmed the presence of the MTPrOPhOPcs and their electroanalysis was excellent towards electrocatalytic reduction of H2O2, with the limit of detection (LoD) and limit of quantification (LoQ) in the ^M range. The electrocatalytic reduction peaks for H2O2 were observed at -0.37 V for Au-PAz-MnTPrOPhOPc and -0.31 V for Au-PAz-CoTPrOPhOPc when Ag|AgCl pseudo-reference electrode was used. The Au-PAz-MnTPrOPhOPc and Au- PAz-CoTPrOPhOPc gold electrode surfaces showed good sensitivity and reproducibility towards the electrocatalytic reduction of hydrogen peroxide in pH 7.4 phosphate buffer solution. , Thesis (MSc) -- Faculty of Science, Chemistry, 2017

- Description: Aim This study aims to provide an understanding and a description of the short-term postfire regeneration and ecology of the fynbos-thicket vegetation on a coastal dune system in the southeastern Cape Floristic Region. Another aim is to assess the recovery of the vegetation community by assessing the growth forms and the disturbance response across a range of species from thicket and fynbos communities and to provide a belowground bud bank classification for each of these species in the coastal dune systems. Location The study site was the Mandela University Reserve and the Noordhoek dune fields, situated in Gqeberha, Eastern Cape, which is part of the south-eastern Cape Floristic Region. The study site hosts thicket-fynbos mosaic vegetation type that occurs in a Mediterranean-Climate Ecosystem (MCE). Methods Firstly, field observations and photographs of plant species were taken weekly to assess and identify the species that were emerging and persisting in the dune system in the first 12 months postfire. Phenological events of the species that emerged (e.g., flowering, fruiting, leaf growth, leaf yellowing, and leaf abscission) were also observed and reported on. Secondly, an excavation of 21 species (e.g., Jamesbrittenia microphylla, Euclea racemosa, Olea exasperata, Searsia laevigata) was conducted to classify the species into their belowground bud bank types. Results There was a rapid emergence of resprouters (facultative resprouters and obligate resprouters) in the first 12 months postfire. This was followed by their growth; primarily occurring after the rainfall events. The dominant resprouting species (facultative resprouters and obligate resprouters) entered the system two weeks after the fire. There was a significant difference in the time to the first emergence of the different regeneration groups postfire (P < 0.001): on average, obligate sprouters (OS) appeared 1 month after fire – two months earlier than facultative sprouters (FS) and four months earlier than non-sprouters (NS). There was no statistical evidence to suggest that the FS and non-sprouters NS emerged at different times postfire; however, most NS species were observed in the system 5 months after fire. 4 Exceptions were the NS species Pelargonium grossularoides and Mesembryanthemum aitonis, both annuals that emerged 1 month after fire. A wide range of OS species that appeared earlier in the system (e.g., Euclea racemosa, Olea exasperata, Searsia laevigata, and Lauridia tetragona) exhibit underground lateral growth with belowground bud banks (BBBs) from which they recover after disturbance. In total, six BBB types were recorded in this study, namely: bud-bearing root, rhizome, rhizophore, woody rhizome, stem tuber, and corms. The bud-bearing root from woody species was the dominant BBB in this system. Main conclusion The return of species that occurs in the first year after fire occurs rapidly in the first 2 months as resprouting species (primarily OS) appear in the system. Following this, the rate of return of species decreases as reseeding species (primarily NS) gradually reestablish and occupy the gaps in the dune fynbos-thicket vegetation. This study has shown that plant species in this ecosystem are adapted to fire disturbance as their populations are able to reestablish through various regeneration strategies, including resprouting from different types of BBB. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: This study's overall objective was to investigate communal farmers' perceptions on production practices and evaluate pre-slaughter responsiveness of extensively reared Boran and Nguni steers. On objective one farmers’ knowledge and perceptions on cattle breeds, management, and marketing channels in selected villages of Alice, Eastern Cape, South Africa were evaluated. Interviews were conducted using a structured questionnaire divided into demographic information and relevant cattle production practices, following a snowball technique to select 101 cattle-keeping households from Gaga, Ntselamanzi, and Ncerha villages. Most of the interviewed cattle farmers were males (65percent), in the age range of 40-60 years, with a primary-matric educational level. Among others, they highlighted financial security (47percent) and traditional ceremonies (26percent) as the reasons for keeping cattle. Most dominant in their herds were the Boran (49percent) and crossbreds (23percent) reared extensively with some supplementation (nutritional and medicinal). Their breed selection was based on disease and tick tolerance, temperament, and product (milk and meat) quality. It was noted that most of the interviewed cattle owners have the basic knowledge of good management practices, breed differences, and marketing chains. They related to low productivity to diseases, lack of knowledge, and poor resources. On the second objective pre-slaughter blood-based stress indicators and their subsequent effects were evaluated on beef quality of extensively reared Nguni and Boran steers . Twenty steers (10 Nguni and 10 Boran) aged 18 months were divided into two groups (with 5 of each breed per group) and transported from the University of Fort Hare Honeydale farm to the East London abattoir in the morning and afternoon trips. Upon arrival at the abattoir, the steers were held in lairage units for 24 hours (group 1) and 16 hours (group 2) until slaughter. Blood samples were drawn using a needle and vacutainer tubes from each steer's jugular vein at the farm before transportation, upon arrival at the abattoir, and during slaughter to perform cortisol, glucose, and routine haematological analysis. M. longissimus dorsi samples were harvested on the left side of each carcass to measure the meat quality attributes. Interactions between the observed production-stage activities, breeds, and physiological changes of these steers were recognized; with cortisol and glucose increasing (P ≤ 0.05) during transportation (4.15±0.46 ng/mL and 5.35±0.46nmol/L respectively) and also with farm group 1 showing higher cortisol (42.62±14.47 ng/mL) than the second group. Furthermore, all steers that were in slaughter group 1 showed less cortisol (101.49±14.47 ng/mL) and glucose (6.50±14.47 nmol/L) levels than those in group 2. In addition, Boran steers had higher packed cell volume, erythrocyte count, and haemoglobin values (33.27±0.54 percent, 7.66±0.19 106 μL, and 11.15±0.16 g/dl respectively) compared to Nguni steers in all production-stages. Later in the experiment, the effect of breed type, production stage activities (farm handling, transportation, and lairage duration), and stress responsiveness on some meat quality parameters (pH, lightness (L*), redness (a*), yellowness (b*), hue, Chroma, thawing and cooking loss, and tenderness) collected from the steers were measured. It was observed that the group lairaged for 16 hours produced the highest L* value (36.25±0.88) compared to those lairaged for 24 hours. As for the b* and hue of the meat, there were positive interactions between the breed type and the production stages (p<0.05). Lastly, cooking loss and tenderness were significantly affected by the breed type in all groups, with Nguni having the most tender meat (24.06±1.39 percent) and less cooking loss (16.92±1.33 percent) than Boran breeds. Therefore, the production stage conditions and breed type influenced some physiological stress-indicators and meat quality of Boran and Nguni steers raised on natural pastures. However, there were not many differences observed between the groups and breeds. , Thesis (MSc) -- Faculty of Science and Agriculture, 2020

- Description: This study's overall objective was to investigate communal farmers' perceptions on production practices and evaluate pre-slaughter responsiveness of extensively reared Boran and Nguni steers. On objective one farmers’ knowledge and perceptions on cattle breeds, management, and marketing channels in selected villages of Alice, Eastern Cape, South Africa were evaluated. Interviews were conducted using a structured questionnaire divided into demographic information and relevant cattle production practices, following a snowball technique to select 101 cattle-keeping households from Gaga, Ntselamanzi, and Ncerha villages. Most of the interviewed cattle farmers were males (65percent), in the age range of 40-60 years, with a primary-matric educational level. Among others, they highlighted financial security (47percent) and traditional ceremonies (26percent) as the reasons for keeping cattle. Most dominant in their herds were the Boran (49percent) and crossbreds (23percent) reared extensively with some supplementation (nutritional and medicinal). Their breed selection was based on disease and tick tolerance, temperament, and product (milk and meat) quality. It was noted that most of the interviewed cattle owners have the basic knowledge of good management practices, breed differences, and marketing chains. They related to low productivity to diseases, lack of knowledge, and poor resources. On the second objective pre-slaughter blood-based stress indicators and their subsequent effects were evaluated on beef quality of extensively reared Nguni and Boran steers . Twenty steers (10 Nguni and 10 Boran) aged 18 months were divided into two groups (with 5 of each breed per group) and transported from the University of Fort Hare Honeydale farm to the East London abattoir in the morning and afternoon trips. Upon arrival at the abattoir, the steers were held in lairage units for 24 hours (group 1) and 16 hours (group 2) until slaughter. Blood samples were drawn using a needle and vacutainer tubes from each steer's jugular vein at the farm before transportation, upon arrival at the abattoir, and during slaughter to perform cortisol, glucose, and routine haematological analysis. M. longissimus dorsi samples were harvested on the left side of each carcass to measure the meat quality attributes. Interactions between the observed production-stage activities, breeds, and physiological changes of these steers were recognized; with cortisol and glucose increasing (P ≤ 0.05) during transportation (4.15±0.46 ng/mL and 5.35±0.46nmol/L respectively) and also with farm group 1 showing higher cortisol (42.62±14.47 ng/mL) than the second group. Furthermore, all steers that were in slaughter group 1 showed less cortisol (101.49±14.47 ng/mL) and glucose (6.50±14.47 nmol/L) levels than those in group 2. In addition, Boran steers had higher packed cell volume, erythrocyte count, and haemoglobin values (33.27±0.54 percent, 7.66±0.19 106 μL, and 11.15±0.16 g/dl respectively) compared to Nguni steers in all production-stages.

- Description: Stakeholder theory has long put forth the concept that managerial attention must be given to all stakeholders towards the realisation of value creation opportunities. Through the process of stakeholder engagement, and through the adoption of stakeholder inclusivity principles, an organisation can position itself to reap the benefits of understanding the legitimate needs and interests of all its stakeholders by seeking to satisfy all its stakeholders in turn. This study analysed the integrated reports of five retail banks, whose main base of operations were in South Africa, to assess the board’s ability to create value for its stakeholders through adopting a stakeholder inclusive approach to corporate governance as advocated for by the King Code on Corporate Governance in South Africa – King IV™. This assessment was done through an examination of a selection of outcomes relevant to the banking industry and related to each of the six capitals that form part of the value creation process as indicated for in the Integrated Reporting Framework (IIRC, 2013): 1) Financial Capital, 2) Manufactured Capital; 3) Intellectual Capital; 4) Human Capital; 5) Social and Relationship Capital, and; 6) Natural Capital. The results obtained, over a three-year period – 2018 to 2020, revealed that while the directors had a firm understanding of who their material stakeholders were, they struggled to create value that catered to all their stakeholders collectively. In addition, the directors were also unable to create sustainable value over the assessment period. As a result of this, most banks, with the exception of one, were unable to realise the value creation opportunities that could have led to a potential source of competitive advantage. The study concludes that while no observable sustainable competitive advantage was evident over the period of assessment, the concept of stakeholder inclusivity is an important corporate governance principle that drives value creation and, as such, warrants more attention from the director’s point of view. This research is intended to contribute to the growing knowledge on the importance of stakeholder inclusivity in corporate governance execution. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2022

- Description: The purpose of this study was to revisit the topic of colonialism once more, in order to ascertain whether it had both negative and positive impacts in Africa. This is so because colonialism is mostly renowned for its negative attributes, therefore, the study attempted to give a more balanced analysis of colonialism and its effects on the colonies and colonised subjects. To this effect, the study examined four African texts: Chinua Achebe’s Things Fall Apart(1967), Ngugi wa Thiong’o and Ngugi Wa Mirri’s I Will Marry When I Want (1982), Mongo Beti’s Mission to Kala (1957) and Sembene Ousmane’s The Last of The Empire (1983). The analysis showed that colonialism did have damaging and constructive impacts on the former colonies. However, these constructive impacts have their limitations where Africans are concerned. The study also came to the conclusion that despite the destructiveness of colonialism there are vital aspects of the Western civilisation that need to be and have been accommodated by Africans. Therefore, amalgamating the positives of various cultures rather than trying to separate them, is the way forward for people of any race as the world has undeniably become a global village. It is easy to see the wrongs and injustices of European Imperialism in Africa. African culture was damaged. The Europeans did not understand tribal differences and tribal customs. They did not even try to understand. The Europeans forced the Africans to learn new ways. They tried to make the Africans feel inferior. They forced the Africans to accept European government, religion, and languages. They drew up colonial boundaries without giving any thought to splitting up tribes. Some of the things the Europeans did in Africa helped the natives. But most of those things were done for the sake of the Europeans. Railway systems, roads, and schools were built and the continent of Africa was opened up to the rest of the world. , Thesis (MA) -- Faculty of Social Sciences and Humanities, 2011

- Description: This study explores how through music discourses and representations of identity and authenticity are articulated through a reading of hip hop and rock music scenes in post-apartheid East London. I have read through interviews, spaces where performances occur and material culture associated with the artists, of musicians moving between ideas of resistance to the mainstream as well as conforming in their representations of identity. The tensions aroused by these underground music scenes in my study ran between resistance and conforming narratives in relation to how musicians express how they make sense of identity and authenticity in the changing post-apartheid landscape. Therefore the complex readings of identity derived from the study showed how contradictory music allows one to be. Further the study found that the assertions about race, ethnicity and identity were often more subtle and contradictory at times, which warranted one to pay closer attention to these music scenes. Inasmuch as musicians attempted to move out of the mainstream by placing themselves in an alternative positioning, they remained limited to ‘authentic’ articulations of identity, where race remained either ‘invisibly’ white or problematically ‘native’ as centres of authentic representation. Moreover the study was able to show the anxieties and tensions around citizenship, identity and belonging. , Thesis (MA) -- Faculty of Social Sciences and Humanities, 2014

- Description: More than a decade ago, South Africa realized the significance of Information and Communication Technology (ICT) and its use in delivering several services; there are still several challenges that block implementing an ICT-based system to deliver services and information better. Since communal development is still one of the country's biggest concerns, ICT is among several advances and views recognized for speeding up communal development and providing for the country's economic growth. This research aimed to investigate and implement ICT tools for communal farmers in the context of information needs and information dissemination. The research concentrated on the technical tools and skills needed to implement an ICT tool for communal farmers and other stakeholders. A prototyping methodology was used in this research in the development of the required prototype. A study was then conducted to understand the present state and the information needs of communal farmers where the questionnaire was administered. The research results demonstrated the critical need for communal farmers to get information timely at their convenience. A mobile database system was then designed and developed that suits communal farmers' nature. This system was an offline android application that assists with their information need and its dissemination, and it allows the sharing of the communal farmer's data to other stakeholders. , Thesis (MSc) (Computer Science)-- University of Fort Hare, 2021

- Description: This study is concerned with the promotion of local music creatives. The literature explores ways to help the independent music creatives successfully navigate in the music industry by adopting a protean career profile. The research question that was explored in the study was whether or not the independent popular female creatives in the city of Gqeberha’s music industry adopted protean career profiles for successful career navigation. These pop music creatives’ profiles were compared to those of classical creatives for further insight. Relevant literature was analysed to collect data about what international authors have discovered about creatives’ successful navigation of their careers. The information that was gleaned from the analysis indicated that numerous individuals have adopted the profile of the protean career to successfully navigate their environment. The rationale for adopting the protean career profile was that it is directly related to one’s employability. Although the working world (including the music industry) is rapidly changing, this notion of employability will enable an individual to remain updated about the latest trends in their work environment and thus successfully navigate that environment. This concept was applied to research among music creatives in the South African (SA) context. Although there was limited research on the protean career profile, the published research findings that were available indicated that employability and information were in alliance with the international research on the protean career (which constitutes one’s employability). Employing qualitative data collection procedures, the researcher interviewed 14 independent female music creatives with different backgrounds, roles and experiences. Interviews were semi-structured one-on-one as well as focus groups. This narrative strategy of inquiry helped determine whether or not these individuals had adopted the protean career for successful navigation of their working environment. After data collection the researcher engaged in a cyclical coding process for deep analysation of the data utilising atlas.ti. The data was reduced from codes to categories, and eventually towards linking categories. The findings from the study revealed that the participants’ environment (surroundings) did not sufficiently support them, the creatives do not have sufficient guidance in their music paths and not all of them had adopted the protean profile. , Thesis (MA) -- Faculty of Humanities, School of Visual and Performing Arts, 2021

- Description: Rhodes University (RU) has been offering a MEdME (Masters in Education, Mathematics Education) degree in Namibia for over 12 years without evaluating its success and impact. This study aimed to evaluate the MEdME programme’s impact on the graduates and on mathematics education in Namibia from the perspectives of its graduates. The study also evaluated the factors that enabled or limited the impact of the programme from the perspective of RU staff members. A three-phased research study was implemented to achieve this. Phase I was a MEdME theses audit to analyze what each graduate researched which then guided the sampling process. Phase II was a distribution of a questionnaire to willing MEdME graduates to elicit their views about the programme's impact. In Phase III, selected graduates were interviewed to follow up on the questionnaire. The RU academic staff members were also interviewed about the programme's design and rationale, as well as their perspectives on its impact on graduates' professional lives. The study found that graduates believed that the programme made them more critical reflexive practitioners (CRPs) who: are now self-introspective, can reflect in context and are competent researchers. This is a sign of the programme attaining its objectives of developing and growing CRPs and graduates, who have advanced in their fields, including their ability to do research. The programme also created opportunities for graduates to study further and/or publish papers. The programme further opened up opportunities for graduates’ promotion into positions of influence in the Ministry of Education where they can positively impact on mathematics education transformation in Namibia (METN). The graduates consequently noticed improvements in some areas but they also noticed room for improvement in other areas of mathematics education in Namibia. This study therefore suggests that more mathematics teachers study further, improve their research capacity and contribute more to METN. The study also suggests a national campaign to increase mathematics teachers' content knowledge. Furthermore, the programme should reintroduce coursework to address students’ subject content knowledge. RU is also advised to explore offering a Professional MEd in Namibia for students who want to focus more on improving their mathematics content knowledge. It is also proposed that Namibia establish a research bank where researchers can upload their theses for wider dissemination. , Thesis (MEd) -- Faculty of Education, Education, 2021

- Description: Tuberculosis (TB) is most commonly a pulmonary infection caused by the bacterium Mycobacterium tuberculosis. With the exception of the COVID-19 pandemic, TB was the most common cause of death due to an infectious disease for a number of years up until 2020. In 2019, 10 million people fell ill with TB worldwide and 1.4 million people died (WHO, 2020a). Additionally, multidrug-resistant TB (MDR-TB) remains a public health crisis and a health security threat. A global total of 206 030 people with multidrug- or rifampicin-resistant TB (MDR/RR-TB) were reported in 2019, a 10% increase from 186 883 in 2018. South Africa is ranked among the 48 high TB burden countries, with an estimated 360 000 people falling ill in 2019, resulting in 58 000 deaths, the majority of which being among people living with HIV. Unlike HIV, however, TB is a curable disease when managed correctly with long durations of antitubercular chemotherapy. Pyrazinamide (PZA) is an important first-line tuberculosis drug unique for its activity against latent TB. PZA is a prodrug, being converted into its active form, pyrazinoic acid (POA) by the Mtb gene pncA, coding for the pyrazinamidase enzyme (PZase). TB resistance to first-line drugs such as PZA is commonly associated with mutations in the pncA/PZase enzyme. This study aimed to identify potential novel inhibitors that bind to the active site of PZase. By making use of molecular docking studies and molecular dynamics (MD) simulations, high throughput virtual screening was performed on 623 compounds from the South African Natural Compounds database (SANCDB; https://sancdb.rubi.ru.ac.za). Ligands that selectively bound to the PZase active site were identified using docking studies, followed by MD simulations to assess ligand-PZase complex stability, Finally, hit compounds identified from the first round of MD simulations were screened again against PZase structures with high confidence point mutations known to infer PZA resistance in order to identify any novel compounds which had inhibitory potential against both WT and mutant forms of the PZase enzyme. , Thesis (MSc) -- Faculty of Science, Biochemistry and Microbiology, 2021

- Description: Climate change, severe weather events, population growth and, urbanisation are just a few of the leading causes contributing to the global water crisis. This global water crisis is negatively impacting the environment, and society, which includes business (large and small). Businesses are facing many water risks and challenges in their daily operations, such as water scarcity, water stress and water pollution, which are resulting in them being negatively impacted financially. For all business to overcome these risks and challenges which are negatively impacting their operations and to assist in protecting the scarce water resources left on the planet, the implementation of water stewardship practices will play a very important role. The literature has fallen short in addressing water stewardship frameworks and practices for small business. Through a sustainability lens underpinned by Natural Resource Based View Theory, this research study sets out to develop a water stewardship framework for implementation by small business to provide them with a competitive advantage. By reviewing the current literature and frameworks available to large business organisations, the insights gained allowed for a draft water stewardship framework to be developed from this literature, suitable for small business. This draft water stewardship framework for small business was used to gather further information on its suitability for small business, through an interview process. A qualitative interview process with seven small businesses in Makhanda (South Africa), allowed for data to be gathered and used to refine and adjust the draft water stewardship framework for small business. The findings from this research study show that small business do not have a global awareness of water problems and are not aware of the concept of water stewardship. Small business were very receptive to the draft water stewardship framework for small business and felt that its implementation would make a difference in saving scarce water resources and create a competitive advantage for them. The study concludes by recommending a water stewardship framework for small business (WSF4SB), who will play a leading role in fighting the water crisis. The implementation of the WSF4SB aims to provide small business with a sustainable competitive advantage by looking after scarce water resources ensuring there is sufficient water for current and future generations. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2023

- Description: The legacy of apartheid created uneven development in South Africa, which led to lack of effective service delivery, high levels of poverty and unemployment. This resulted in many people within the communities being vulnerable to poverty. In response to the retarded development, the post apartheid government formulated a number of policies and legislations. Local Economic Development (LED) is one of the policies mandated to guide developmental local government initiatives in addressing poverty, unemployment and redistribution. The aim of the study was to assess LED as a mechanism for poverty alleviation, focusing on the effectiveness of the LED strategies employed by the selected municipalities in Amathole District Municipality (ADM). The literature and the empirical study revealed that LED is seen as a tool through which socio-economic development can be achieved. To achieve the objectives of the study, the study employed both quantitative and qualitative research methods. A thematic content and pie chat analysis were employed to analyse data, which was gathered using questionnaires, interviews, non-participant observation and documentary survey. The findings of the study revealed that LED strategies have a significant impact on improving infrastructure and service delivery, have both a pro-poor and a pro-growth focus on improving the general welfare of the residents and that LED agencies play a pivotal role in promoting sustainable development, thereby alleviating poverty. Though the current LED strategies employed by ADM are deemed to be effective, they do not fully meet the intended goal of eradicating poverty. Therefore, the researcher recommended that the municipalities should, inter alia, encourage responsible leadership, expand capital investment, promote capacity building and communities should be fully committed in working together with the municipalities in promoting sustainable development. , Thesis (MPA) -- Faculty of Management and Commerce, 2011

- Description: The concept of political corruption is crucial in political discourses. Since the 1990s, there has been a massive resurgence of focus on political corruption. Definitional accounts of the concept have been proposed. This work is a critique of the accounts that have since been provided. I argue that these definitions are inadequate, offering an alternative. The predominant definition of the concept is that it refers to public officials’ violations of public office rules due to their respective interests in private gain. I consider this wrong for three reasons. First, politics includes more than the activities of public officials. Second, that is not the only behaviour that is contrary to the moral imperatives of politics. Third, the lack of political integrity is not just about acting wrongly. It also includes the possession of political vices. Observing the inadequacy of the dominant perspective, Seumas Miller offers a more comprehensive definition. He defines political corruption as any act that despoils the moral character of political actors and undermines the processes and purposes of legitimate political institutions. However, his definition is also insufficient. First, he includes some immoral non-political acts as examples of political corruption, although he agrees that political corruption entails immorality in politics. Second, he unjustifiably excludes some immoral political actions as denoting political corruption. In contrast, I define political corruption as possessing political vices or acting contrary to moral, political imperatives. This definition is a comprehensive reflection of what it means to lack political integrity. My thesis begins with a critical account of politics and its moral imperatives. That is the criteria for determining what political corruption is. , Thesis (MA) -- Faculty of Humanities, Philosophy, 2021

- Description: The contemporary educational landscape in South Africa is characterised by prevailing inequities and disparities within higher education institutions and poor academic achievement. Although participation in higher education has increased over time, many students do not complete their courses within the required time and a high proportion of students continue to drop out, with few students progressing to postgraduate level. Majority of students who do not complete their courses are poor. Many students are faced with a number of barriers that stand in the way of academic success and, ultimately, graduation. However, through agency students often draw from a range of supports to promote their well-being and academic success. This study aims to balance the literature by investigating not only the barriers, but also the supports to success in university. This study addresses the notion that students from historically black universities are underrepresented in the literature. The current study explored Eastern Cape students’ barriers and supports to success within higher education. Five undergraduate female students participated in focus groups, which incorporated photovoice, adding to the participative nature of the research methodology. Focus group data were subjected to thematic analysis, informed by social constructionist theory. Three themes were prevalent: barriers within higher education, coping strategies positioned on a continuum and supports in higher education. Descriptions revealed that barriers and supports are reinforced by prevailing discourses, which are critiqued and/or used for the benefit of the students’ well-being. Barriers were limiting, yet also sites for personal growth and agency, whilst the engagement with supports was mediated predominantly by the intersection of social categories (race, gender, socio-economic status) occupied by students. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2020

- Description: Institutions of higher learning are experiencing high failure rates, and this according to Scott, Yeld and Hendry (2007) can partly be attributed to the lack of adequate support for students after they have been admitted. Adequate support is very necessary, since research has shown that many students, especially those from former Department of Education and Training, are underprepared for tertiary institutions. Students at the Ibika Campus, the site where the research took place, are predominately from the former Department of Education and Training. The objective of this study therefore was to investigate why students at the Ibika Campus of the Walter Sisulu University seem to encounter problems with English mastery even though English language support services have been instituted; to discover what the perceptions of the WSU students and staff were with regard to the English support services; to determine what challenges the support services had , if any, in providing best service and to ascertain whether the English support services could be enhanced. The research was conducted at the Ibika Campus of the WSU. The design was that of the case study and a mixed method methodology was used. A total sample of 142 students, 5 staff members from the library, 1 staff member from the WC and 5 staff members from computer laboratories, as well as 12 staff members from the Ibika campus participated. A non probability sampling method was used. Students were selected from 1st year, second year and third year of their respective studies, ranging across the 14 departments at Ibika campus. Lecturing staff members were also selected across these departments. The instruments were structured questionnaires and interviews. The findings indicated that the English support services faced many challenges in their endeavor to provide services to students and the conclusion is that the English Language support services were therefore not as effective as it could be in giving support to students. It is recommended that the English Language support services immediately be improved in terms of space, since the venues for all three support services are too small, human resources and resources that support Teaching and Learning. It is further recommended that the university authorities seriously consider implementing an assessment test for all new entrants to the university, in order to establish who were in need of English Language support, and that these students be immersed in a programme that will assist them to improve their English Language proficiency. Finally, it is recommended that students complete a graduation threshold English proficiency examination in order that the institution can have confidence that students are proficient in English. , Thesis (MA) -- Faculty of Education, 2011

- Description: The interventional life writings of second generation life writers (young, black, middleclass South Africans) in post-apartheid South Africa have not attracted much academic debate in spite of the burgeoning of such writings recently. The intersection of race, class and gender in post-apartheid South Africa remains a problem and a rich site of research, hence this research’s reading of four selected life writings by young, black, middle-class South Africans living in post-apartheid South Africa: Fred Khumalo’s Touch My Blood: The Early Years (2006), Malaika Wa Azania’s Memoires of a Born Free: Reflections on the Rainbow Nation (2014), Khaya Dlanga’s To Quote Myself (2015) and Tumi Morake’s And Then Mama Said… Words That Set My Life Alight (2018). Using the intersectional approach, the study explores the lives narrated by second generation South Africans, in a manner similar to the grand narratives because of their historical and social context. The study focalises life/self-writers who have experienced post-apartheid trauma of being racialized, gendered and classed in a democratic country. This is a shift from the staple analysis of lives of political struggle against apartheid, narrated by historical legends such as Nelson Mandela. The study then, by focusing on ‘small voices’ closes a critical gap created by over-attention paid to grand narratives in South African life writing. Self-narrations by young, black, middle-class South Africans emerge not only as a way of narrating history but also as a means of making history. Through the deployment of the intersectional approach (the interconnectedness of inequalities) to analyse the systems of oppression associated with democratic South Africa, the four selected interventional life writers reveal how their experiences and identities are an outcome of constantly renegotiating power relations. , Thesis (MA) -- Faculty of Humanities, Social Sciences and Law, 2020

- Description: Giant kingfish Caranx ignobilis, the largest species in the family Carangidae, are global icons as apex marine predators. They are widespread in tropical to subtropical regions globally, where they are of high importance to ecosystems and fisheries. During summer, adults aggregate for spawning, making them vulnerable to overfishing. The world’s largest recorded C. ignobilis aggregation is in southern Mozambique. Some of these aggregating individuals (an unknown proportion) have been recorded passing into South African waters. Furthermore, a unique aggregation of adult C. ignobilis in South Africa’s Mtentu Estuary has attracted global attention but remains unexplained, hence warranting investigation. Research on C. ignobilis globally has shown relatively small home ranges. Research in southern Africa has been limited and inconclusive. Thus, the broad aim of this study is to describe the movement patterns of C. ignobilis from southern Africa. Long-term (36 years) mark-recapture data from the Oceanographic Research Institute’s Co-operative Fish Tagging Project, comprising 3 729 tagged C. ignobilis and 144 recaptures, were analysed. While 74% of recaptures were recorded < 1 km from the tagging location, long-distance movements of up to 419 km were also recorded (mean = 15 km). Although adults moved significantly (p < 0.01) greater distances than juveniles, they also displayed high levels of site fidelity. Seasonal trends included evidence of a summer migration; however, there was still considerable uncertainty regarding exact movements. Therefore, 43 C. ignobilis were acoustically tagged and subsequently monitored along the east coast for over five years with the Acoustic Tracking Array Platform’s passive receiver array. All acoustically tagged adult C. ignobilis migrated to southern Mozambique each year (with minor exceptions), from distances of up to 632 km. When not migrating, South African-based fish showed consistent inter-annual fidelity to individual home ranges. Although coastal home range length (excluding migrations) varied considerably between individuals, even the mean length (92 km) was greater than any previously recorded C. ignobilis home range, globally. In contrast to the southern Mozambique aggregation, the Mtentu Estuary aggregation seems to comprise of individuals showing fidelity to that region. The passive tracking of eight acoustically tagged individuals in the Mtentu Estuary revealed clear trends. Statistical modelling showed that estuarine presence was strongly associated with periods of cold coastal upwelling. Diel movement patterns showed that the utilisation of warm surface waters ~ 4 km upstream during the day was followed by nightly departures to the mouth or sea. Thus, it is likely that this majestic aggregation is for thermal refuge; specifically, for daily re-warming after feeding in cold waters at night. Findings from this study are of global ecological interest and have direct applications for local fisheries management and the development of sustainable eco-tourism. Protecting these vulnerable aggregations is of the utmost importance for the future of this species in southern Africa. , Thesis (MSc) -- Faculty of Science, Ichthyology and Fisheries Science, 2022

- Description: Giant kingfish Caranx ignobilis, the largest species in the family Carangidae, are global icons as apex marine predators. They are widespread in tropical to subtropical regions globally, where they are of high importance to ecosystems and fisheries. During summer, adults aggregate for spawning, making them vulnerable to overfishing. The world’s largest recorded C. ignobilis aggregation is in southern Mozambique. Some of these aggregating individuals (an unknown proportion) have been recorded passing into South African waters. Furthermore, a unique aggregation of adult C. ignobilis in South Africa’s Mtentu Estuary has attracted global attention but remains unexplained, hence warranting investigation.
