- Description: Land degradation is widespread in communal rangelands in the grassland biome of South Africa, and often attributed to overstocking and lack of coordinated management. Excessive pressure on the herbaceous component has contributed to the uncontrolled spread of opportunistic invasive alien woody species e.g. Acacia mearnsii in many degraded areas, resulting in significant loss of ecosystem service capacity, along with soil and land productivity. Short-duration overnight kraaling has been suggested as a tool for restoring degraded rangelands. Recent studies in semi-arid savannas and shrublands have reported increased grass cover, soil nutrients and palatability and concluded that short-duration kraaling is a low-cost and effective way of restoring degraded rangelands using livestock. However, the response of different plant functional types and communities to such intense livestock impact may vary depending on local context. This study used twelve paired kraal and control sites to investigate the effects of short-duration (7-24 days) overnight kraaling of livestock on herbaceous vegetation and soils in a mesic grassland. The study area is generally considered to be overgrazed but has considerable variation in grass composition and basal cover. Sites included relatively intact natural grassland and sites where wattle infestations had been cleared and where mostly bare ground remained. I tested the hypotheses that overnight kraaling would result in (1) increased basal cover due to introduction of grass seed and stimulation of germination through hoof action, (2) increased infiltration due to hoof action, and (3) increased soil nutrients and organic matter due to dung and urine deposition. I also hypothesized that factors such as a site’s initial grass cover, its slope, the occurrence and amount of rainfall before and during kraaling, and the kraaling intensity (number of livestock and duration of the kraaling event) would influence the magnitude and direction of the kraaling effect. The effect of kraaling on vegetation was strongly dependent on initial condition. Kraaling increased basal cover of grasses when sites had low initial basal cover, but decreased basal cover if initial values were over 50%. Infiltration increased if kraaling took place during or after rain but decreased if kraaling took place when soils were dry. Kraaling increased soil P and K. In mesic grasslands, short-duration overnight kraaling is promising as a tool for rehabilitating degraded sites but should be avoided where the grass sward is relatively intact. I recommend that the suitability of kraaling be further evaluated per vegetation type and local context. , Thesis (MSc) -- Faculty of Science, Botany, 2023

- Description: Sternophysingidae Holsinger, 1992 is a monotypic subterranean amphipod family endemic to Namibia and South Africa. It currently has eight described species under the genus Sternophysinx. The species in this family are considered narrow endemics, having only been identified using morphological characters. However, the apparent wide distribution of certain species, reported in several subterranean waters in different provinces, suggests that our current taxonomic understanding of these species needs to be completed, thus needing revision. Further, detailed knowledge of the distribution and phylogenetic relationship between species of this taxon still needs to be improved. This study aimed to use integrative taxonomy to analyse both morphology and molecular biology to study hidden diversity and to further our understanding of the distribution in this taxon. The available morphological keys were used to identify species, and 12S rRNA was also used to investigate the relationships of Sternophysinx species and delimit species boundaries. The study primarily aimed to use mitochondrial cytochrome c oxidase subunit I (COI). However, due to technical issues such as getting the correct primers, this study's aims were altered, and 12S was used instead of CO1. However, the process of getting CO1 sequences is still ongoing, and the results will be made available elsewhere. The current study aimed to visit all the type localities of the seven species of Sternophysinx reported in South Africa, including all known localities in which these amphipods have been recorded in the past. Nevertheless, this study did not get samples from Nelspruit, De Hoop Nature Reserve, and Nash Nature Reserve, which cover type localities of S. travaleensis, Matlapitse and Chaos cave that harbours S. calceola. Instead, the current study added five new localities Graaff-Reinet, Beaufort West, Hogsback, Makhambathi Nature Reserve and Ntsikeni Nature Reserve, for the distribution, including two new provinces (i.e., Eastern Cape and KwaZulu-Natal) that had records of this genus in the country. Three delimitation methods, Assemble Species by Automatic Partitioning (ASAP), Bayesian implementation of the Poison Tree Processor (bPTP) and Automatic Barcode Gap Discovery (ABGD), were used to identify cryptic species within Sternophysinx. Phylogenetic analyses and three delimitation methods (ASAP, bPTP and ABGD) revealed considerable hidden cryptic diversity within this Sternophysinx. Preliminary morphological examination revealed at least two species as undescribed from Bakwena and Sterkfontein caves, and several that were morphologically identified using the current taxonomic keys did not match with the molecular analysis. For example, S. basilobata from three different systems, Boesmansgat cave (Northern Cape), Beaufort West (Western Cape) and Potchefstroom (North West), was in genetically different putative species. The same is true for S. robertsi and S. alca in Ficus and Peppercorn cave in Limpopo. Overall, the results of the current study demonstrate the need for a comprehensive integrative taxonomic revision of Sternophysinx. These findings suggest that S. basilobata is a complex of distinct lineages and requires further study. On the other hand, species delimitation methods suggested that there are 12- 14 candidate species (Figure 2.5). Lastly, this study investigated the threat posed by the invasive koi fish introduced to an important cave, Boesmansgat cave in the Northern Cape, which is a type locality of two endemic species (S. megacheles and S. basilobata). Stable isotope (δ13C and δ15N) and gut content analyses of the fish were investigated to establish whether this invasive fish feed on these critical creatures, thus endangering their long-term survival. Stable isotope signatures and the stomach gut content proved to be helpful in determining the diet of the koi fish, revealing it to be an omnivorous feeder with high invertebrate preference, including amphipods. These results indicate that the introduction of koi fish in the Boesmansgat cave threatens the long-term sustainability of these amphipods and other invertebrate assemblages in this cave. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2023

- Description: While laboratory workers are essential in many industries, they are also at a high risk of developing musculoskeletal disorders (MSDs). Manual pipetting has been identified as the leading cause of MSDs in laboratories because it exposes operators to high forces, repetition, static muscular loading, and awkward wrist postures for prolonged periods. The main contributors to the high risk associated with manual pipetting are the design of manual pipettes and how they are used. A laboratory-based study was conducted to assess and compare the biomechanical, subjective, and performance responses of an ergonomically designed pipette model to those of a traditional model. In a simulated laboratory workstation, 20 individuals performed 40 repetitions of pipetting tasks using each pipette model. Dependent variables consisted of muscle activity (of the Abductor Pollicis Brevis, Opponens Pollicis, Extensor pollicis longus, Abductor pollicis longus, Extensor pollicis brevis, and brachioradialis muscles), wrist postures, time to task completion, perceived muscular exertion (measured using the Borg RPE scale), perceived comfort and usability, and user preference. The results revealed that an ergonomic modification to pipette design has some effect on biomechanical and subjective outcomes. The ergonomic model significantly reduced muscular loading of the Opponens pollicis, and Abductor pollicis brevis muscles. The ergonomic model also reduced radial deviation and was associated with better subjective responses, while the time to task completion did not change. This study found that an ergonomic modification to pipette design can improve user comfort and well-being without compromising performance. Overall, the findings emphasize the importance of addressing pipette design to reduce the MSD risk associated with manual pipetting, and the necessity for a user-centred approach to tool design. , Thesis (MSc) -- Faculty of Science, Human Kinetics and Ergonomics, 2023

- Description: Land use shifts from commercial agricultural farming to game farming through wildlife tourism, has been prevalent in post-apartheid South Africa. Scholars have argued that wildlife tourism to be more profitable than other forms of commercial farming. As such, game farming has been promoted as a community-engaged vehicle for rural development through the creation of better employment opportunities. This study explored the implications of these shifts on the livelihoods of farm workers living on the game farms. Unlike labour tenants, farm workers who live on the private game, earn a wage. However, farm workers’ accommodation on the game farm is dependent on them being employed on the farm. The aim of the study was to explore the impacts of game farms on the livelihoods of farm workers since the shift from commercial agricultural practices to tourism services in the form of private game reserves. A case study research design was used to gather in-depth information about the multiple realities of the participants, not only about their employment relationships, but also their experiences living on the property on which they are employed. I collected data mainly through semi-structured interviews. I also collected and analysed company documents. The study adopted a Sustainable Livelihoods Framework as a theoretical schema to analyse the livelihood assets readily available to the farm dwellers and the various livelihood strategies they used to make ends meet. The findings of the study revealed that residing on the game farm, although it provided access to free accommodation, tended to pose several challenges to the workers, including i) exploitative employment structures and ii) insecure land rights. The findings also revealed human capital development initiatives mandated for employees were not formally documented. As a result, employees were confined in their current employment. Consequently, the study revealed that participants who had been employed by the game farm for over a decade showed little evidence of enhanced livelihoods. The livelihood strategies of the participants were their basic employment wage, the use of money borrowing systems through stokvels, and informal trading such as selling sweets and chips in the game reserve villages where other workers live with their families. , Thesis (MA) -- Faculty of Humanities, Sociology, 2023

- Description: Computational estimation is important in the development of learners’ number sense. It is through the process of finding an approximate (but satisfactory) that learners can check the reasonableness of their answers to calculations, develop an understanding of place value and by implication the four number operations. It is the role of teachers to develop the computational estimation skills of learners. To do this, teachers need to have a sound knowledge of computational estimation, its value and how to teach it. This study thus seeks to explore and understand Namibian senior primary teachers’ mathematical and pedagogical content knowledge to develop their learners’ computation estimation knowledge. The research is guided by the following question: What mathematical and pedagogical content knowledge do senior primary mathematics teachers draw on to develop their learners’ computational estimation skills? The research is a qualitative interpretivist case study. Eight senior primary teachers of Mathematics from the Ohangwena region in Namibia participated in the study. Data was generated through questionnaires, a focus group interview and lesson observations. The Mathematics Knowledge for Teaching (Ball et al., 2008) and the Knowledge Quartet (Rowland, 2005) frameworks were used as both analytic and explanatory tools for the study. Key findings from the research are that teachers have knowledge of and use a variety of strategies for estimation, however, they only use the ‘rounding off’ strategy when teaching learners computational estimation. The teachers appear to teach computational estimation by first focusing on place value before moving on to ‘rounding off’ to the nearest 10s, 100s, 1000s and so forth. My research recommends that the National Institute of Educational Development together with the Ministry of Education, Art and Culture in Namibia, provide teachers with professional development opportunities on how to develop learners’ computational estimation. Such professional development will further develop teachers’ mathematical and pedagogical content knowledge. Furthermore, the Namibian syllabus should include a variety of strategies for computational estimation. , Thesis (MEd) -- Faculty of Education, Primary and Early Childhood Education, 2023

- Description: The COVID-19 pandemic in South Africa has been mainly discussed in terms of its socioeconomic effects and loss of life. While these are important, its mental health effects are given attention in this dissertation. In particular, this is explored through social media platforms, which saw increased usage as a result of regulations on movement to slow the Virus’ spread. This is explored during the hard lockdown (or ‘Alert Level 5’) and further, focuses on young adults, key users of social media platforms. Max Weber’s ‘social action theory’ and Michel de Certeau’s ‘theory of everyday life’ are drawn on, which help to analyse social relations from an individual level; and are used to explore the kinds of expressions made on a social media platform, and what can be said in mental health terms. These theoretical frameworks are applied to a university “Confessions” page, used mostly by young adults, where submissions were made anonymously. Findings indicate a great deal of trauma associated with the COVID-19 pandemic, but also evidence of the emergence of collective responsibility. They show the immense sacrifices made by participants for the opportunity of an education, and provide a window into the kinds of subjectivities experienced by South African young adults. Further, they show the importance of having more substantive mental health discussions in South Africa, a country familiar with traumatic experiences. , Thesis (MA) -- Faculty of Humanities, Sociology, 2023

- Description: Covid-19 a novel pandemic, has wreaked havoc globally, threatening the livelihoods of all, including refugees and asylum seekers. Like all other countries globally, South Africa has gone to great lengths to mitigate the challenges that this pandemic has caused. However, it is far from clear whether these responses are according due regard to the rights of some of the most vulnerable in society, amongst which are refugees. This thesis deals with South Africa’s obligation to provide social security to refugees during the Covid-19 pandemic. It specifically assesses whether South Africa's responses to the Covid-19 pandemic were in adherence to fundamental refugee law principles relevant to the protection of refugees. The study commences with a general introduction, followed by an analysis of the international human rights and refugee law framework relevant to protection of refugees. This framework is used to assess South Africa’s responses. Subsequently, the discussion delves into South Africa’s own national framework on social security. Using the standards identified in both the national and international frameworks, the thesis then proceeds to measure South Africa’s Covid-19 related responses regarding social security to resolve the issue of whether South Africa adhered to these standards in as far the protection of refugees’ right to social security is concerned. , Thesis (LLM) -- Faculty of Law, Law, 2023

- Description: Covid-19 a novel pandemic, has wreaked havoc globally, threatening the livelihoods of all, including refugees and asylum seekers. Like all other countries globally, South Africa has gone to great lengths to mitigate the challenges that this pandemic has caused. However, it is far from clear whether these responses are according due regard to the rights of some of the most vulnerable in society, amongst which are refugees. This thesis deals with South Africa’s obligation to provide social security to refugees during the Covid-19 pandemic. It specifically assesses whether South Africa's responses to the Covid-19 pandemic were in adherence to fundamental refugee law principles relevant to the protection of refugees. The study commences with a general introduction, followed by an analysis of the international human rights and refugee law framework relevant to protection of refugees. This framework is used to assess South Africa’s responses. Subsequently, the discussion delves into South Africa’s own national framework on social security.

- Description: Mental distress is a universal phenomenon experienced by many individuals despite age, race, gender, occupation, or socio-cultural context and is slowly becoming a major contributor to the burden of disease in South Africa. However, mental distress fails to take precedence in SA because of inherent intricacies in understandings about it, as a result of ways of being conceptualised and interpreted differently across cultures. This research study explored amaXhosa healthcare workers’ understandings, knowledge, practices, and attitudes regarding mental distress amongst some amaXhosa people. The study aimed to investigate what mental distress means for some people who belong to the amaXhosa ethnic group, to uncover how they conceptualise mental distress, seek help or what behaviours prevent help-seeking. It aimed to highlight any prevalent attitudes of stigma and discrimination, to build insight into overlooked aspects in psychotherapy practice especially when dealing with non-western populations. The study utilised interpretative phenomenological analysis (IPA) as its analytical lens; to explore and to enter as far as possible into the worlds of participants to generate rich data and in-depth analysis. Four participants were recruited through both purposive and snowball sampling and data were gathered using individual semi-structured interviews. From the data collected, the findings illustrate a limited understanding of mental distress amongst some amaXhosa people due to lack of education and awareness on the subject, leading to the apparent silence in discussing such matters and inadvertently predisposing it to being viewed as taboo. The predominant themes as evidenced by the data were the use of language that sensationalises mental distress; misinformation; Afrocentric beliefs that rationalise mental distress; alienation and segregation of those affected; and the primary healthcare system as a source of reinforcing prevalent stigma and discrimination. The findings show a link between constructs around mental distress and the prevalent socioiii cultural environment, denoting that some perspectives can be linked to observations or modelling in childhood, from people in the respective communities in which people live. , Thesis (MA) -- Faculty of Humanities, Psychology, 2023

- Description: Cancer is a devastating disease that is a leading cause of death worldwide. Despite the available cancer treatments, there is a significant need to improve the therapeutic approach towards this disease. Photodynamic therapy (PDT) is an alternative approach for treating cancer, which requires a photosensitiser, molecular oxygen and light. Although some porphyrin-based derivatives have been approved by the United States Food and Drug Administration (FDA) and other similar agencies elsewhere for photodynamic therapy, their relatively poor photophysicochemical properties mean that there is an ongoing need for new photosensitiser dyes. Singlet oxygen photosensitiser dyes can also be used to treat bacteria that develop antimicrobial resistance in the context of photodynamic antimicrobial chemotherapy (PACT). The main aim of this study was to synthesise and characterise a series of porphyrin dyes with 4-quinolinyl, thien-2-yl and 4-bromo-thien-2-yl meso-aryl groups and their Sn(IV) and In(III) complexes, as well as their corrole analogues. Corroles are contracted macrocycles that have interesting optical properties. The corroles selected for study were found to be difficult to synthesise and purify and had unfavourable photophysicochemical properties and were thus omitted from the PDT and PACT biological applications within this thesis. High- and low-symmetry A4 and ABAB type meso-tetraarylporphyrins porphyrins were synthesised to improve the photophysicochemical properties of the photosensitisers; the utility of these dyes as photosensitisers was studied against the MCF-7 breast cancer cell line for PDT and against Staphylococcus aureus and Escherichia coli for PACT. The thienyl-2-yl rings were introduced to red shift the lowest energy Q band towards the phototherapeutic window, while quaternisation of the nitrogen and sulfur atoms of the 4-quinolinyl and thien-2-yl rings to introduce a cationic nature was explored to improve the bioavailability of the drugs and uptake into the target cell walls for improved efficacy. Heavy Sn(IV) and In(III) central metal ions were introduced to enhance the singlet oxygen quantum yields and limit aggregation through axial ligation. The bromine atoms of the 4-bromo-thien-2-yl meso-aryl rings were also introduced to enhance the singlet oxygen quantum yields of the dyes. Furthermore, the utility of the porphyrin and corrole molecules for optical limiting properties to limit laser radiation to protect optical devices, including eyes, was explored by the z-scan technique. One of the dyes studied, Sn(IV) tetrathien-2-ylporphyrin, that exhibited the most favourable reverse saturable absorbance (RSA) response was embedded into a poly(bisphenol carbonate A) polymer thin film to further explore its suitability for practical applications. , Thesis (MSc) -- Faculty of Science, Chemistry, 2023

- Description: South Africa is a country that has experienced premature deindustrialisation due to its inability to move out of middle-income status. The role of industrial policy in South Africa is pivotal to taking the country to greater economic heights and a higher-income status. South Africa’s historical context indicates that the country experienced its highest GDP growth rates during the apartheid economy. Since the demise of apartheid, the post-apartheid economy has experienced poverty and economic inequality that the South African government cannot eradicate. This thesis addresses the failure of South Africa to overcome premature deindustrialisation, and it discusses the state of the political economy and economic growth in a pre-apartheid and post-apartheid context. The thesis also addressed the significance of industrial policy through the establishment of the Industrial Policy Action Plan (IPAP). The shortcomings and successes of IPAP form a critical part of the research and present an analysis of different economic sectors. This thesis also assesses the state of industrial policy using two countries as case studies: Brazil and South Korea. , Thesis (MEcon) -- Faculty of Commerce, Economics and Economic History, 2023

- Description: This thesis argues that the characters in Nadifa Mohamed’s oeuvre exhibit both vulnerability and agency and that their position in society oscillates as if between two poles, as they cross social and spatial boundaries. There is no existing scholarly research that focuses on child migrants in Mohamed’s texts specifically. Here, Black Mamba Boy, The Orchard of Lost Souls and The Fortune Men are analysed and compared with a central focus on the child migrant characters to examine her portrayal of conflict-induced migration and its impact on vulnerable communities. In Black Mamba Boy, Mohamed portrays Jama’s exilic journey where he leaves his homeland of Hargeisa and migrates across territorial borders in Northeast Africa to find his father. His quest brings him from Somaliland to Sudan as he walks through countries that are devastated by the war between the British and Italian colonial forces in the 1930s. As Jama attempts to cross the spatial distance between himself and his father he also treads the invisible line between life and death. Along his journey, Jama is exploited and abused by colonial troops and traumatised by the conflict he witnesses. Mohamed revisits her father’s precarious journey not to portray him as a victim but to make him “a hero, not the fighting or romantic kind but the real deal, the starved child who survives every sling and arrow that shameless fortune throws at them” (1). Thus, the text is an account of Jama’s strength as he miraculously survives the brutalities of war. Similarly, in The Orchard of Lost Souls, the child protagonist, Deqo, is a refugee with parents. She internally migrates through Hargeisa at the moment the region breaks out into the Somali Civil War. Deqo attempts to keep herself out of harm’s way as the town is destroyed by soldiers and rebel groups who have opened fire against civilians. As a female child migrant Deqo occupies a particularly vulnerable position as she navigates a space where gender-based violence is used as a method of war. Despite the dangers around her, Deqo actively seeks out safety and a path that will free her from the tightening grip of the war. The Fortune Men depicts Mahmood’s journey of migration as an adult. When he attempts to cross the border into Wales he is ostracised, abused, and dehumanised because of his difference. Jama and Deqo’s exilic journeys are compared to Mahmood’s unsuccessful migration and the children cross borders that adults cannot cross because they use their vulnerability to seek out opportunities and change their environment. This thesis is situated within the theoretical framework of transnational and diasporic literature with a specific focus on the impact of forced migration on child migrants. Through close engagement and comparison of the three primary ii texts mentioned, this thesis demonstrates the vulnerabilities and fluctuating agencies of characters to highlight their liminal positioning. , Thesis (MA) -- Faculty of Humanities, Literary Studies in English 2023

- Description: This study investigated the possible effect of insecticide drift on naturalized biological control agents of Pontederia crassipes (Mart.) Solms-Laub (Pontederiaceae), in the Lowveld region of Mpumalanga Province of South Africa. Occurrence and abundance of biocontrol agents were recorded at three sites on the Crocodile River and at three dams adjacent to citrus orchards. Leaves of P. crassipes and water samples were collected for insecticide residues and also nutrient status of the water and plants. Eccritotarsus catarinensis Carvalho (Hemiptera: Miridae), Neochetina spp. (combined) (Coleoptera: Curculionidae), and Orthogalumna terebrantis Wallwork (Sarcoptiformes: Galumnidae) were recorded with notable variation in abundance between the river and dams across regions. Insecticide residues were not detected on all leaves sampled across study regions, however, nutrients were detected with nitrate ranging between oligotrophic and mesotrophic. Phosphorus was also detected, but, neither of the nutrients correlated with the occurrence and abundance of naturalized biological control agents of P. crassipes. Bioassays were conducted to measure the effect of commonly used insecticides (viz. Methomyl and Chlorpyrifos) on the survival and feeding damage of biological control agents of P. crassipes. Survival of individual insects was recorded between 0.5 and 120 hours for Megamelus scutellaris and Neochetina eichhorniae Warner (Coleoptera: Curculionidae) adults for treatments where insecticides were topically applied onto the insects or leaves were dipped into the pesticides. Concentrations below field rates, recommended and above field rates of Methomyl and Chlorpyrifos on either exposure techniques significantly reduced survival and feeding of biocontrol agents. Methomyl was more toxic compared to Chlorpyrifos and it significantly reduced the survival of M. scutellaris and N. eichhorniae. In conclusion, in this study, population abundance of biocontrol agents of P. crassipes at the Lowveld region of Mpumalanga was not influenced by pesticide drift, but, insecticides commonly used in the citrus orchards has the potential to negatively impact naturalized biological control of P. crassipes as demonstrated by the bioassays. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2023

- Description: The research uses a richly contextualised case study of Rhodes University to explore the role of local level agency in a just green transition. The central concept of the thesis is mainstreaming sustainability. Sustainability has become a core objective both at the macro and micro levels. The just green transition and triple bottom line are shorthand for these macro and micro concepts. At the macro level, there is increasing evidence suggesting that transitioning to a sustainable economy can be a key driver of economic development. At the micro level, the elements of the triple bottom line increasingly overlap, with sustainability no longer a separate goal, or a ‘nice to have’, but integral to organisational success. However, this potential is clearly not being realised, and sustainability often remains ‘niche’. Lack of progress at the macro-level reinforces the importance of bottom-up, local level agency. In keeping with the broader micro-level literature, the case study strongly suggests that mainstreaming sustainability would have multiple benefits. These include reducing dependence on unreliable state-provided services and enhancing Rhodes University’s standing as a genuinely transformative institution. The evidence suggests that there is a pure financial case for green investments, such as the construction of a solar farm at Rhodes University, even before accounting for the social and environmental benefits of such an initiative. This shifts the focus to why institutions like Rhodes University have not been proactive in mainstreaming sustainability. The document analysis and the interviews showed that there is an awareness of the importance and potential of mainstreaming sustainability. However, the funding squeeze is often misperceived as a binding constraint, and there is an absence of innovative thinking about how to finance projects with high returns, such as a solar farm. A theme amongst several of the interviewees was that the university should embrace a policy of enhancing small changes as a way of mainstreaming sustainability gradually. Even here, there are doubts about whether the organisational structure of the university will allow this. On the other hand, there are positive signs that the increasing sense of crisis means management and other key stakeholders are gradually shifting towards seeing the crucial importance of the university embracing a more proactive stance. , Thesis (MCom) -- Faculty of Commerce, Economics and Economic History, 2023

These include reducing dependence on unreliable state-provided services and enhancing Rhodes University’s standing as a genuinely transformative institution. The evidence suggests that there is a pure financial case for green investments, such as the construction of a solar farm at Rhodes University, even before accounting for the social and environmental benefits of such an initiative. This shifts the focus to why institutions like Rhodes University have not been proactive in mainstreaming sustainability. The document analysis and the interviews showed that there is an awareness of the importance and potential of mainstreaming sustainability. However, the funding squeeze is often misperceived as a binding constraint, and there is an absence of innovative thinking about how to finance projects with high returns, such as a solar farm. A theme amongst several of the interviewees was that the university should embrace a policy of enhancing small changes as a way of mainstreaming sustainability gradually. Even here, there are doubts about whether the organisational structure of the university will allow this. On the other hand, there are positive signs that the increasing sense of crisis means management and other key stakeholders are gradually shifting towards seeing the crucial importance of the university embracing a more proactive stance. , Thesis (MCom) -- Faculty of Commerce, Economics and Economic History, 2023

- Description: The right to education in section 29(1)(a) of the Constitution was meant to signal a break between an education system divided along racial lines, and a new democratic education system based on equity, equality, and opportunity for all learners. In reality, the South African education system still remains deeply divided along racial lines, with poor, mostly black learners, being under-resourced by the state, while their richer, mostly white, counterparts are being taught in schools that have access to all the resources necessary to realise the right to basic education. As a result, the right to education in section 29(1)(a) of the Constitution has been heavily debated, and between 2010 and 2022, the South African courts have often been called on to interpret the right. In the process, a rich jurisprudence has developed on the core content of the right to basic education, with findings by the courts that the right includes an entitlement to a number of educational resources. These include access to school infrastructure, learner-teacher support materials, desks and chairs, scholar transport, teaching and non-teaching staff, and nutrition. This study examines the way South African courts, between 2010 and 2022, have interpreted and implemented the right to basic education to give effect to section 29(1)(a) of the Constitution. While South African courts have historically shied away from interpreting socio-economic rights to contain a minimum core content and have rather opted for a reasonableness approach, the same is not entirely true for section 29(1)(a). As stated above, courts have been willing to find that the right entails a minimum basket of goods and services without which the right cannot be realised. By examining some of the most important education rights cases during this period, the study proposes that there are five factors that have guided the courts’ interpretation of the right and has assisted in the courts finding that the right contains a minimum core content. These factors are the historical context of the right to basic education; the textual formulation of the right to basic education in section 29(1)(a) of the Constitution; the interrelatedness of the right to basic education and other rights within the Bill of Rights; subsidiary education policies, legislation, and regulations, and lastly, the role of international law. This study seeks to consider the extent to which each of these factors have played a role in courts’ interpretation of section 29(1)(a). The study also considers the implementation of these judgments and the role that the courts have played in realising the right to education for learners on ground-level. , Thesis (LLM) -- Faculty of Law, Law, 2023

- Description: The primary purpose of this study is to examine the experiences of students with learning disabilities in accessing assistive technology at South African universities. The field of learning disabilities is relatively emerging in South Africa. Critical scholarly literature demonstrates that universal access, democratic participation and inclusion remains a challenge for students with learning disabilities in higher education. This research is informed by the Social Model of Disability (SMD) and the Universal Design for Learning (UDL), which are considered vital elements of disability inclusion and transformation in higher education. The social model of disability provides valuable insights into social barriers that continue to marginalise, discriminate and exclude those living with disabilities. This research is primarily qualitative using in-depth semi-structured interviews. Quantitative surveys were utilised to further complement the research. The unit of analysis in this study were students with learning disabilities, academic, library, disability unit, Student Affairs Services and ICT staff members. Two universities were chosen for this purpose: one with a dedicated disability unit and another one still in its infancy in establishing a disability unit. The findings indicate that the disability services offered to the students at the two institutions are qualitatively different. This study reveals glaring gaps at institutional level in the nature and extent of support services available to students with learning disabilities: lack of adequate resources including funding, inaccessible assistive technology, lack of training and expertise and staff attitudes in dealing with students with learning disabilities. The study found that after the students with learning disabilities disclose, they are neglected, and experience negative attitudes and stigma. The study showed that sometimes it is hard and expensive to get accommodations as a student with learning disabilities. The findings suggest that having a dedicated disability unit increases inclusion and awareness about available services compared to universities that do not have them. A concern was raised by the staff members that students with disabilities do not make use of the available assistive technology. This study calls for integrating the universal design for learning with assistive technology to enhance the inclusion of students with learning disabilities in South African universities. This will assist students with learning disabilities to achieve better academic outcomes and complete their tasks more efficiently and independently. This study recognises that the provision of disability services is a costly enterprise but service delivery needs to be fast-tracked regardless. , Thesis (MA) -- Faculty of Humanities, Sociology, 2023

- Description: Multiple factors contribute to the prevailing mental health conditions of South Africans. According to Kaminer and Eagle (2010, p.8), 75% of South Africans are trauma survivors, half of whom have experienced multiple traumas, some directly and some indirectly. However, many trauma survivors are not adequately treated due to the limited access and availability of mental health specialists in the country. Thus, mainstream medical treatments ought to be supplemented by alternative forms of therapy such as creative-arts therapy that cater to the wide demographic range of citizens in South Africa. This research aims to explore the efficacy of creative-arts therapies as a treatment for trauma-related mental health conditions in South Africa from the perspectives of three practising creative-arts therapists. The research is a qualitative study and uses Interpretive Phenomenological Analysis (IPA) to interpret the data. The research participants consisted of three accredited creative-art therapists practising in Music, Art, and Dance. The participants were interviewed using semi-structured, in-depth interviews which were conducted online. The interview data was transcribed and analysed using the IPA framework provided by Smith, Flowers and Larkin (2009). The results yielded three superordinate themes which were supported by eight subordinate themes. The results suggest that creative-arts therapies are underutilized in South Africa due to a lack of public awareness and general (mis)perceptions about mental health conditions. Furthermore, access to these therapies in formal settings is limited as they are not offered as treatment options in public health facilities, which negatively impacts the viability of creative-arts therapies practice in the country. Creative-arts therapies offer several unique benefits to individuals of all ages, backgrounds and abilities as they do not require prior artistic knowledge or experience to participate in treatment. In addition, they are non-verbal which helps to bridge the language and cultural barriers that often arise as a result of South Africa’s diverse cultural population. Finally, creative-arts therapies are an effective method of treating mental health conditions incurred through trauma as they focus on accessing stored trauma in the body or unconscious mind through a natural and non-judgemental platform of creative expression. As a result, they address the physical, emotional, psychological, and cognitive effects of trauma while empowering the individual. In conclusion, this research suggests that creative-arts therapies are highly effective in the treatment of trauma-related mental health conditions, particularly in a country like South Africa which experiences high incidents of trauma. They should be better integrated into public health care facilities so that they are accessible to the general public. This will result in an increase in the use of creative-arts therapies as a treatment option for mental health conditions, particularly those related to trauma. It would also help to address the limited awareness and poor perceptions of the nature of mental health, mental illness, mental health care and mental health care services. , Thesis (MMus) -- Faculty of Humanities, Music and Musicology, 2023

- Description: This research sought to investigate how African languages function as a communicative tool in a university where English is the medium of instruction. The study's purpose is to provide a systematic review of research that has been carried out on language attitudes towards isiXhosa as a language of learning and teaching (LoLT) in higher education. The study reveals that South African higher education institutions such as Rhodes University mostly use English as the LoLT- a language which for most lecturers is not their first/home language but helps ease communication in a multilingual community. Rhodes University is characterised by multilingualism because the university community is made up of diversity in culture, language, and educational background of the people. Previously explored language attitude studies are based on students’ views and this study investigated RU lecturer views and opinions towards isiXhosa as a LoLT. The study focused on the importance and the need (if any) of isiXhosa in a multilingual higher education institution. The study reveal that language barriers are one of the difficulties, but academic cultural differences seem to play a crucial role that can impact on the learning and teaching outcomes. This can lead to negative experiences and the forming of stereotypical views. These views include how lecturers are and should be trained to teach mathematics, science, and academic studies in African languages. The SA higher education practices and language use (i.e., monolingual language policy) are one of the reasons that the implementation of indigenous languages in education policies in SA is fraught with difficulties due to several factors. Amongst the factors is the fact that indigenous languages are not yet fully developed as academic languages. The study further reveals that lecturers find it difficult to teach mathematical studies in isiXhosa because of lack of terminology in the language for academic purposes particularly at a tertiary level. Furthermore, existing literature highlights the importance of the use of code-switching which is a beneficial practice for lecturers in assisting their students who struggle with English as a LoLT at RU. The lecturer views towards isiXhosa as a LoLT at RU is not only on language barrier but also about the lack of development in the language use in spaces where only English is believed to be the best such as language for academics. The study also reveals an integration of Information Communication Technology in education and how language appears as a barrier. , Thesis (MA) -- Faculty of Humanities, School of Languages and Literatures, 2023
