- 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: 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 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

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

- Description: Climate change has caused a combination of effects on the physiology of fishes. Of particular concern are the effects of thermal variability and ocean acidification. Organismal energy budgets change throughout ontogeny and research into the metabolic scope during early life stages is particularly useful in identifying potential bottlenecks. The first part of this thesis aimed to assess the absolute aerobic scope (AAS, described as the difference between the maximum and standard metabolic rates) of individual juveniles from a protected population of the endemic, commercially important seabream, Chrysoblephus laticeps, across a range of ecologically relevant temperatures (T = 11, 14, 18, 22˚C) under present-day conditions (pH = 8.03, pCO2 ≈ 420 μatm) using intermittent flow respirometry. The second component sought to investigate how long-term exposure (from fertilisation to juvenile, ~100 days exposure) to high-pCO2/hypercapnic conditions (pH = 7.63, pCO2 ≈ 1400 μatm), would affect the AAS of juvenile C. laticeps over a range of temperatures. Lower pH conditions were predicted to cause a decrease in the AAS of treatment animals due to additional energetic costs of acid-base regulation. The findings of the first data chapter demonstrated that juvenile C. laticeps reared under current CO2 conditions are tolerant to a wide range of thermal conditions, and individuals with a broad aerobic scope will be the best suited to coping with enhanced thermal variability. In contrast to the expected outcomes of the second data chapter, juvenile C. laticeps reared under high pCO2 conditions displayed greater AAS at high and low temperatures when compared with specimens from high pH conditions. Whilst a high degree of individual phenotypic variation was observed in the metabolic response of both groups, this was reduced at the lower and upper extreme temperatures for high pH and low pH animals respectively. Notably, the variation in treatment animal’s SMR was significantly diminished across all temperatures tested, compared to only a localised reduction in the SMR of high pH animals at cold temperatures. This may be indicative of compensatory pathways affecting energy restructuring and thermally-governed physiological trade-offs under hypercapnia. Given these results, juvenile C. laticeps appear to be more resilient to ocean acidification than anticipated, potentially owing to intrapopulation metabolic phenotypic diversity. This is likely attributed to the parental lineage originating in the Tsitsikamma MPA, which is thought to boast greater phenotypic diversity as a consequence of the refuge that these conservation areas offer from exploitation. Owing to the restriction imposed by the availability of surviving, captive-reared juveniles, the sample size used in this study was relatively low. However, owing to the repeated-measures nature of this research the sample size was sufficient to offer suitable statistical power for the polynomial mixed model used in the analysis. Future research should incorporate both physiological and behavioural responses to multiple environmental stressors to better understand covariation between these two traits, and to detect any behavioural trade-offs that might arise through compensation. In addition, these trials should be repeated using offspring from outside of the MPA to compare whether the same level of resilience and metabolic phenotypic diversity would be present in an exploited population. , Thesis (MSc) -- Faculty of Science, Ichthyology and Fisheries Science, 2023

- Description: The discourse of identity and community are topics of interest to me. As a citizen living in post-apartheid South Africa, I am captivated by the re-emerging wisdom and knowledge of Nguni cultural philosophies and practices. My practice-based research is interested in a creative interpretation of these ancient philosophies and practices in the context of postcolonial life. The project in many ways re-members through observation of socio-political issues such as inequality, violence, and vandalism as reflections of internal challenges of the individual self in current reality. In essence, my discussion in this paper highlights the need for healing grief and loss for the well-being – physical, emotional, mental, and spiritual – of society. Self-definition is the core of any community and we see this in the philosophy of the African proverb umntu ngumntu ngabantu, ‘I am because you are’. ‘I am’ is a set of beliefs that construct the individual self; our life’s course then becomes a constant molding of the body and the world around us. The wisdom of ubuntu was, and is, a catalyst for many African cultures, as this law recognizes each individual as important and equal in the community. As a descendant of various indigenous clans originating in Africa the well-being and balance of my being is determined by how much I know about who I am. Consequently, being a part of the generation that is experiencing the transitioning phases from apartheid I question the ways we are dealing with the residue of coloniality concerning all aspects of self; the physical, emotional, and mental bodies of self. My creative work is a reflection of the exercises I implemented to cultivate selfhood as a way to participate in and control my reality as a marginalized member of society. The different chapters touch on many intersecting theories about tools for healing/soothing the self. The creative process experimented with the various concepts embedded in the expression ‘I am because you are’. In the process of this research, I learned that knowing yourself is one of the principles of ubuntu, which teaches me that I cannot be or give what I do not have. The themes I explore through the above expression are self-love, self-acceptance, and self-respect using a creative lens. This practice-based research proposes a concept; the act of love as a decolonial gesture. My exhibition Vuleka Mhlaba Ndinegene1 utilizes visual language to convey the need for more conversations on healing using natural elements, as a way to make a connection between self, the natural environment, and community. In the first and second chapters, the paper focuses on practices employed by artists such as Lhola Amira, Guadalupe Maravilla, Buhlebezwe Siwani, Tony Gum, Lina Iris Viktor, and Aida Muleneh, to relate the various approaches to re-member the severed connection between self, nature, and community. This study looks at theories on; holding space, sound healing, earthing, shadow work, astrology, and human consciousness. , Thesis (MFA) -- Faculty of Humanities, Fine Art, 2023

This practice-based research proposes a concept; the act of love as a decolonial gesture. My exhibition Vuleka Mhlaba Ndinegene1 utilizes visual language to convey the need for more conversations on healing using natural elements, as a way to make a connection between self, the natural environment, and community. In the first and second chapters, the paper focuses on practices employed by artists such as Lhola Amira, Guadalupe Maravilla, Buhlebezwe Siwani, Tony Gum, Lina Iris Viktor, and Aida Muleneh, to relate the various approaches to re-member the severed connection between self, nature, and community. This study looks at theories on; holding space, sound healing, earthing, shadow work, astrology, and human consciousness. , Thesis (MFA) -- Faculty of Humanities, Fine Art, 2023

- Description: Visualisation is commonly used as a tool in introducing algebra through visual or kinaesthetic sequences designed to prompt learners' development of a general rule for moving from a term's position to its output value. Fluency in both the concepts and the conventions of elementary algebra are essential to learners, as algebra forms the language in which many advanced mathematical ideas are encoded. Moreover, algebraic fluency is often associated with an ability to think abstractly about arithmetic processes. In many classrooms, however, research has shown that learners often focus on fluency in algebraic conventions rather than concepts, learning how to manipulate expressions without understanding the algorithms they are taught to follow. This trend can be linked to several causes, including teacher-centred mathematics classrooms in which learners are – whether implicitly or explicitly – encouraged to copy formulae and methods in order to ‘get it right in a test’ without necessarily grasping the underlying logical relationships. This case study, therefore, aimed to determine whether there was value in using visual, kinaesthetic models to broaden and deepen learners' use of algebra. To that end, in the context of an extra-curricular mathematics club that aimed to decentre the teachers and demand innovative ideas of the participants, six pairs of Grade 9 learners were tasked with creating visual representations of a linear algebraic expression using coloured building cubes. The responses to this task over the course of five assignments were many and varied and almost universally displayed a sustained internal logic that the learners were able to explain and develop. Most pairs began with a visual list of terms arranged in sets of towers, pyramids or, in one case, a spiral. At the end of the study, all but one of the pairs had settled on a Visual Expression, in which various colours were used to represent elements of the algebra such as the values of the coefficient, the variable and the constant term. The participants' representations grew in complexity over the course of the study and the conformity of the final responses showed that the club was a collaborative space in which learners shared ideas. However, the structure of the Visual Expressions and their own confessions of nerves about ‘getting it wrong’ in the interviews suggest that the participants were stuck in a mindset that led them to seek out and idealise the representation closest to the original algebra, even though that representation revealed little about the structural relationship underlying the expression. , Thesis (MEd) -- Faculty of Education, Secondary and Post-School Education, 2023

- Description: This dissertation tests the claim made by a large membership-based organisation that it is a social movement. The organisation, Vulamasango Singene (VS) operates across the rural areas of large parts of the Eastern Cape Province. It has, for twenty years, advocated for the re-opening of land restitution claims for a specific category of forced removal known as “betterment”. This study provides an analysis of an organisation that has yet to achieve its objective in spite of sufficient financial resources, logistical and strategic support, numeric strength and the legal clarity of its demand. The research is situated within the framework of social movement theory. The study examined the origins, institutional infrastructure, demographic make-up, activities and culture of VS. These were analysed against four components that are identified in the literature as key characteristics of a social movement. These are: (i) informal networks (as opposed to structured and managed engagements); (ii) a plurality of actors (as opposed to a homogenous grouping); (iii) mobilising around issues of conflict; and (iv) sharing common beliefs and demonstrating solidarity. Data were gathered through an archival study and field research. Semi-structured interviews were carried out with a sample of VS’s leadership, and staff of the non-governmental organisation in which VS originated, as well as expert informants in the land reform arena. The findings with respect to each of the criteria were: (i) VS’s structure was rigid and internal communication was largely formal. (ii) There was almost no demographic or political diversity within VS. (iii) VS had, in the past, mobilised around issues of conflict, but there had been no mobilisation for ten years. (iv) While there was some evidence of sharing common beliefs and demonstrating solidarity, this was limited. The conclusion reached was that VS is not a social movement. This does not imply that VS is not an important democratic or representative organisation. It does, however, provide a theoretical position from which VS, and other organisations, can direct further action. The study touched on the relationship between northern donors, local professional NGOs and grassroots organisations in South Africa. Interactions among these institutions impact on the way that organisations and social movements develop. Comparisons with other similar organisations were made and similarities and differences were highlighted. It was suggested that, because of the importance of the issue, further research in this regard is necessary. , Thesis (MA) -- Faculty of Humanities, Sociology, 2023

- Description: Poor service delivery is a challenge that has continued to plague the constitutional democracy of South Africa. Legislation has, in response, been passed to ensure efficient service delivery. Despite this legislation, municipal service delivery has been alarmingly poor, and reports on municipal performance and newspaper articles have corroborated this. On the causes of poor service delivery, the existing literature appears to have focused on financial mismanagement, corruption, and the incapacity of officials. Absent from existing literature are discussions on how municipal service delivery is affected by the lack of interrelatedness between municipal public resource management processes (such as revenue collection, expenditure management and oversight). This dissertation addresses this gap by examining the municipal public resource management processes from an oversight perspective. The study sought to analyse the effectiveness of year-end oversight at Amathole District Municipality (ADM) over water and sanitation services. This research aimed to study the year-end oversight over service delivery with reference to the Municipal Public Resource Management (MPRM) model. According to the model, effective service delivery includes inter alia effective oversight, as oversight forms part of the entire system of the municipal resource management cycle. Thus, for the MPRM model, oversight should be exercised on all these processes. The research was a desktop analysis that used both a qualitative and quantitative research methodology. The primary document analysed was the ADM Oversight Report (OR). This report is produced by the Municipal Public Accounts Committee (MPAC) and reflects the year-end oversight conducted by the MPAC on the municipality's activities. In the analysis of the OR, it was concluded that the ADM MPAC had failed to conduct effective year-end oversight of W&S services. The efficacy of the ADM MPAC's year-end oversight was measured against guidelines for effective year-end oversight from the National Treasury and the MPRM model. The findings suggested that there were inefficiencies in the manner that the ADM MPAC exercised its year-end oversight. , Thesis (MA) -- Faculty of Humanities, Sociology, 2023

- Description: Although the Rwandan genocide (itsembabwoko in Kinyarwanda) has often been compared with the Holocaust, in terms of literary and cinematic narratives it has been largely underrepresented, with the notable exception of the release of the films Hotel Rwanda (2004) and Sometimes in April (2005), as well as novels such as Gil Courtemanche’s A Sunday at the Pool in Kigali (2003). However, although there is now a larger oeuvre of works on the subject, they are often not widely known or disseminated beyond their countries of origin. Of even greater concern is the fact that most cinematic narratives on itsembabwoko rely on Western narrative structures in their approach to storytelling. As a result, trauma in these narratives largely tends to focus on the experiences of Western protagonists or on Rwandan protagonists from a Western point of view. This tendency can be tied to the use of Western trauma theory in exploring the effects of the genocide on its witnesses and survivors, at the expense of arguably more relevant postcolonial trauma theory. This presents a problem in theorising the trauma of itsembabwoko, which occurred in a highly specific historical context involving the processes of colonization and decolonization, and in which the difficulties in unifying a population which had been split along socio-economic lines since pre-colonial times remained unresolved. Despite its shortcomings in the postcolonial African context, it would be a mistake to dismiss Yale trauma theory entirely, however, since theorists such as Cathy Caruth still provide valuable insights into the effects of trauma on both the individual and the collective. As a result, I have sought to find commonalities between the two schools of thought, so as to create a more nuanced view of itsembabwoko, its repercussions and the violence preceding it. In writing this thesis, I have selected mostly Rwandan authors, often survivors of the genocide, whose works provide an alternative view of Rwanda’s violent history to that presented in the works mentioned above. Given that the majority of the texts I focus on have been released more recently – mostly the mid-2010s – and are less well-known than their Western counterparts, they provide the opportunity to compare first-hand accounts with those that can only partially recreate the terror of anti-Tutsi violence in Rwanda. My analysis hopefully provides a new perspective on the dominant narratives which have shaped the way in which non-Rwandan (predominantly Western) audiences understand the genocide. The overall aim of this thesis, then, is to demonstrate the importance of placing the genocide and its resultant trauma in a broader historical context, with a view to establishing that it is shortsighted to ignore the impact of pre- and post-genocide trauma on the Rwandan people when discussing itsembabwoko. Though this has been achieved in socio-historical studies, such as Mahmood Mamdani’s When Victims Become Killers: Colonialism, Nativism, and the Genocide in Rwanda, very little has been produced on literary and cinematic representations of the genocide. , Thesis (MA) -- Faculty of Humanities, Literary Studies in English 2023

- Description: The Covid-19 pandemic has created the largest disruption of education systems in human history. The closure of schools and other learning spaces has impacted billions of learners worldwide. The mitigative measures and many new standard operating procedures have brought restrictions and many challenges. The face-to-face traditional teaching method lost its value, and teaching shifted to distance through the integration of technologies. The integration of technologies necessitated the emergency remote teaching process, as it is one of the distance teaching modes that can make teaching possible even for less technologically privileged nations. Literature has shown that the integration and usage of technology during teaching support the development of technological pedagogical and content knowledge (TPACK) of teachers. This study, therefore, sought to investigate how the integration and use of technology during the emergency remote teaching of Covid-19 developed the secondary school teachers’ technological pedagogical and content knowledge. The study is underpinned by an interpretive paradigm, and a qualitative case study approach was employed. It was conducted in seven secondary schools in the Endola education circuit, Ohangwena region, with the purposeful participation of twenty-six secondary school teachers. Data was collected using semi-structured questionnaires and semi-structured interviews. The study was informed by Vygotsky’s (1978) sociocultural theory together with the TPACK framework of Thompson and Mishra (2007) as both theoretical and analytical frameworks. The study's results showed that teachers made use of existing technological resources to sustain their teaching efforts during ERT. They encountered various challenges, including a lack of technological expertise (knowledge) among both teachers and learners. The shift to virtual instruction during ERT supported teachers in developing proficient technological pedagogical content knowledge. This research concludes that schools possess the necessary technological infrastructure to enable teachers to incorporate technology into their teaching methods. Furthermore, it highlights that teachers generally hold favourable attitudes toward integrating technology into their instruction. Nevertheless, it recommends that there is a need for improving both in-service and pre-service teachers’ training and support for effectively teaching in online and blended learning environments. , Thesis (MEd) -- Faculty of Education, Secondary and Post-School Education, 2023

- Description: Nymphaea mexicana Zuccarini (Nymphaeaceae) is an invasive plant originating from southern USA and Mexico that has become problematic in South Africa, invading several water bodies around the country. Manual removal of this plant is very labour intensive and is not cost efficient or effective for long term control, while the use of herbicides is damaging to the environment and expensive. Consequently, this plant is a desirable candidate for biological control, which takes advantage of enemy release of the target weed and aims to re-establish population suppression induced by host specific natural enemies. Initiating biological control requires that several steps are followed to maximise the success of the programme, and the first few of these, including overseas surveys in the native range of the plant, have already been completed. This thesis aimed to continue biological control research for this species to take further steps at effectively managing the plant. Firstly, pre-release surveys in the invaded range are necessary to: determine what factors (including enemy release) contribute to the invasiveness of the target weed; establish a baseline of information to allow for comparison after biological control agents have been released; and identify any insect herbivores that may already be present in the country. The pre-release surveys conducted in this study revealed useful information about N. mexicana invasions in South Africa and provided evidence that enemy release is applicable to this case. However, these studies determined that a native weevil, Bagous longulus Gyllenhal (Coleoptera: Curculionidae), has expanded its host range to include the exotic N. mexicana at three sites, and may thus have potential for management of the species through augmentative releases. The invasion of N. mexicana in South Africa is further complicated by the presence of several Nymphaea hybrids originating from a complex history of horticultural trade. Although previous research has shown that several hybrid groups are present in South Africa, their parentage is not known. As biological control requires the use of host specific insects adapted to overcome the unique chemical and morphological defences utilised by plant species, hybrids are notoriously difficult to manage because they possess intermediate characters inherited from parent species to which natural enemies may not have adapted. Although biological control of hybrids is challenging, other case studies have demonstrated that it is possible to find suitable agents, but the chances of success are increased if putative parents of the hybrids are known so that they can be surveyed for natural enemies. Further molecular studies including possible parents of the Nymphaea hybrids in South Africa were thus carried out in this thesis to focus future surveying efforts. Two main hybrid groups were identified with genetic similarity to two tested putative Nymphaea parents, and this will allow further investigations of these species to improve the chances of successfully managing these hybrid groups. Some of the tested hybrids showed genetic contributions from multiple groups, some of which were unidentified, so it is necessary to prioritise the most problematic hybrids for biological control. With more insight into the genetic makeup of the Nymphaea hybrids in South Africa, investigations into the host specificity of potential biological control agents can be conducted. The ideal biological control agent should have a broad enough host range to impact and survive on both N. mexicana and its hybrids, but without a host range so broad that it would pose risk to native South African species. Host specificity trials are thus necessary to determine the suitability of potential agents. The identification of B. longulus feeding on N. mexicana during pre-release surveys motivated further investigations to determine the natural distribution, field host range, and host specificity of B. longulus in experimentally controlled conditions. Further surveys were therefore conducted at native Nymphaea sites around South Africa in addition to host specificity trials using the native Nymphaea nouchali Burm. f. (Nymphaeaceae), two populations of N. mexicana, and a cultivated hybrid. Results from the surveys and host specificity tests suggest that B. longulus is widely distributed across South Africa, is specific to Nymphaea with no observed preference between N. mexicana and the native N. nouchali, and does not perform well on Nymphaea hybrids. Hence, B. longulus is promising for use in new association biological control through augmentative releases but is not suitable for management of hybrids. In addition to the potential use of the South African B. longulus, it is necessary to conduct host specificity trials for natural enemies from the native range of N. mexicana that were prioritised in previous studies.

- Description: Nymphaea mexicana Zuccarini (Nymphaeaceae) is an invasive plant originating from southern USA and Mexico that has become problematic in South Africa, invading several water bodies around the country. Manual removal of this plant is very labour intensive and is not cost efficient or effective for long term control, while the use of herbicides is damaging to the environment and expensive. Consequently, this plant is a desirable candidate for biological control, which takes advantage of enemy release of the target weed and aims to re-establish population suppression induced by host specific natural enemies. Initiating biological control requires that several steps are followed to maximise the success of the programme, and the first few of these, including overseas surveys in the native range of the plant, have already been completed. This thesis aimed to continue biological control research for this species to take further steps at effectively managing the plant. Firstly, pre-release surveys in the invaded range are necessary to: determine what factors (including enemy release) contribute to the invasiveness of the target weed; establish a baseline of information to allow for comparison after biological control agents have been released; and identify any insect herbivores that may already be present in the country. The pre-release surveys conducted in this study revealed useful information about N. mexicana invasions in South Africa and provided evidence that enemy release is applicable to this case. However, these studies determined that a native weevil, Bagous longulus Gyllenhal (Coleoptera: Curculionidae), has expanded its host range to include the exotic N. mexicana at three sites, and may thus have potential for management of the species through augmentative releases. The invasion of N. mexicana in South Africa is further complicated by the presence of several Nymphaea hybrids originating from a complex history of horticultural trade. Although previous research has shown that several hybrid groups are present in South Africa, their parentage is not known. As biological control requires the use of host specific insects adapted to overcome the unique chemical and morphological defences utilised by plant species, hybrids are notoriously difficult to manage because they possess intermediate characters inherited from parent species to which natural enemies may not have adapted. Although biological control of hybrids is challenging, other case studies have demonstrated that it is possible to find suitable agents, but the chances of success are increased if putative parents of the hybrids are known so that they can be surveyed for natural enemies. Further molecular studies including possible parents of the Nymphaea hybrids in South Africa were thus carried out in this thesis to focus future surveying efforts. Two main hybrid groups were identified with genetic similarity to two tested putative Nymphaea parents, and this will allow further investigations of these species to improve the chances of successfully managing these hybrid groups. Some of the tested hybrids showed genetic contributions from multiple groups, some of which were unidentified, so it is necessary to prioritise the most problematic hybrids for biological control. With more insight into the genetic makeup of the Nymphaea hybrids in South Africa, investigations into the host specificity of potential biological control agents can be conducted. The ideal biological control agent should have a broad enough host range to impact and survive on both N. mexicana and its hybrids, but without a host range so broad that it would pose risk to native South African species. Host specificity trials are thus necessary to determine the suitability of potential agents. The identification of B. longulus feeding on N. mexicana during pre-release surveys motivated further investigations to determine the natural distribution, field host range, and host specificity of B. longulus in experimentally controlled conditions. Further surveys were therefore conducted at native Nymphaea sites around South Africa in addition to host specificity trials using the native Nymphaea nouchali Burm. f. (Nymphaeaceae), two populations of N. mexicana, and a cultivated hybrid. Results from the surveys and host specificity tests suggest that B. longulus is widely distributed across South Africa, is specific to Nymphaea with no observed preference between N. mexicana and the native N. nouchali, and does not perform well on Nymphaea hybrids. Hence, B. longulus is promising for use in new association biological control through augmentative releases but is not suitable for management of hybrids. In addition to the potential use of the South African B. longulus, it is necessary to conduct host specificity trials for natural enemies from the native range of N. mexicana that were prioritised in previous studies. Megamelus toddi Beamer (Hemiptera: Delphacidae) is one such species that was imported into quarantined laboratory conditions from Florida, USA. Host specificity trials were conducted using the same test plants as described for the studies on B. longulus, in addition to multigeneration trials to determine how long M. toddi could survive on non-target host plants. As with the B. longulus studies, no statistically significant differences in preference were observed between N. mexicana and N. nouchali, but M. toddi could not complete development on the test hybrid, indicating that this species is also unsuitable for the management of Nymphaea hybrids. Despite suboptimal plant health, M. toddi completed development for three generations on the native N. nouchali. This lack of host specificity deems M. toddi unsafe for release in South Africa but highlights the importance of following predefined steps to develop a biological control programme. The concluding chapter of this thesis discusses the aforementioned findings in a broader context by considering the driving forces of plant invasions in general and specifically for N. mexicana in South Africa.
