- Description: This is a qualitative research study that examines how young Vhavenḓa women in post-apartheid South Africa views different traditional leadership roles that Vhavenḓa women have historically played and continue to play in Venḓa society. Therefore, the research question that this Master of Arts (MA) research study sought to research is the following: How do young, 21st-century Vhavenḓa women view the traditional leadership roles historically and currently held by Vhavenḓa women in Vhavenḓa society? To grapple with this research question, this study employed a combination of purposive and snowball sampling strategies to recruit seven research participants. Research participants were interviewed using a semi-structured interview approach, which allowed the researcher to build rapport with research participants. Data was manually coded into five themes, namely: 1) The Role of Makhadzi in Traditional Leadership Among the Venḓa Community, 2) The Role of Vhakoma in Traditional Leadership Among the Venḓa Community, 3) The Role of Vhakololo in Traditional Leadership Among the Venḓa Community, 4) The customary practice of male primogeniture and how it contradicts the South African Constitution post-1994, and 5) The socialisation process that puts boys and men on a leadership pedestal. The data was then analysed and discussed in Chapters Four and Five through an Africana Womanist theoretical framework. An important finding in this study is that makhadzi, the father’s sister and also a woman who is a custodian of traditional leadership, is the traditional role that all the participants recognised as the leadership role that Vhavenḓa women have historically played and continue to play. Another role identified by participants as significant within the Venḓa leadership structure is Vhakoma, the Queen Mother and the chief's mother. However, there was limited familiarity with the role of Vhakololo, the royal members or people born into the royal family, as only one participant identified it as a leadership role traditionally occupied by Vhavenḓa women. Research participants suggested that colonial modernity contributes to a lack of knowledge about their culture. Another important finding of this study is that in post-1994 South Africa, there has been a tension between customary practices such as male primogeniture and the South African Constitution. Consequently, some women leaders have used the courts to challenge this practice. Ultimately, this study contributes to the discourse about women’s empowerment and the dismantling of patriarchal structures that undermine women's potential as leaders in the Venḓa context. , Thesis (MA) -- Faculty of Humanities, Political and International Studies, 2025

- Description: In 2015, communities in Malamulele, located in the Vhembe District of Limpopo Province, South Africa, protested against the Thulamela Local Government Municipality, citing inadequate service delivery and favouritism toward Venda-speaking areas. The protesters demanded the establishment of a new municipality for Tsonga-speaking residents, disrupting daily life through road blockades and shutdowns of schools, transportation, and commercial activities. In response, the government demarcated the Thulamela Municipality and created the Collins Chabane Local Government Municipality, which included Vuwani and other Venda-speaking communities. However, this inclusion sparked violent protests in Vuwani in 2016, fueled by claims of insufficient consultation and a desire to remain within the Makhado Local Government Municipality. This study utilised qualitative research methods, specifically semi-structured interviews, to capture the experiences and perspectives of participants from Vuwani and Malamulele. It applied conflict and territory theories to analyse the underlying issues. The findings reveal that colonial policies of divide and rule, along with apartheid-era Bantustan policies, significantly influenced these protests. The study underscores the importance of public participation in community matters, highlighting the unequal provision of services among different groups and emphasising the need for reconciliation. The protests were deeply rooted in the legacy of colonial and apartheid histories and cannot be understood in isolation from these historical contexts and their enduring impacts. This research addresses a gap in the academic literature by exploring the ethnic dynamics and sequence of events in the 2015 Malamulele and 2016 Vuwani protests. It provides insights into the decisions of the government, Municipal Demarcation Board (MDB), and community stakeholders that fueled these conflicts, contributing to a broader understanding of post-1994 ethnic violence and conflict in South Africa. , Thesis (MA) -- Faculty of Humanities, Political and International Studies, 2025

- Description: This study investigates the origins of gender-based violence, along with some of the legal, policing, and socio-cultural barriers to effectively addressing gender-based violence in post-1994 South Africa, as perceived and articulated by Black women activists. To that end, this study conducted semi-structured interviews with eight Black South African women activists involved in the fight against GBV, based in different parts of the country. The analysis and the discussion of the research findings are framed around six themes and theorised through an African feminism lens. A key finding of this research project is that GBV in post-1994 South Africa can be attributed to multiple sources which include poverty, African culture, women’s liberation in post-1994 South Africa, patriarchy, and toxic masculinities. Another finding of the study is that GBV activists joined the fight against GBV for various reasons, which included personal experience with GBV, a development of feminist consciousness, and a desire to change the justice system and how society understands GBV. A consistent theme in the interviews was that the struggle against GBV is not the sole responsibility of women and girls and that society as a whole bears the responsibility for the fight against GBV. While participants recognised the importance of the compulsory South African high school subject – the life orientation syllabus – participants pointed out that this subject tends to focus mainly on unplanned teenage pregnancies, the dangers of sexually transmitted diseases, and HIV prevention among young people in South Africa. Thus, the life orientation syllabus foregrounds the dangers of sex, rather than prioritising encouraging students to recognise GBV and equip students with tools to effectively deal with it. Research participants highlighted the importance and benefits of getting involved in the fight against GBV. Participants further recounted that it was the #TheTotalShutDown movement in 2018 that led to President Cyril Ramaphosa meeting with the organisers of #TheTotalShutDown and forming an organising committee, consisting of representatives from the presidency, non-profit groups, and the organisers of #TheTotalShutdown, who worked together to produce the National Strategic Plan against GBV & Femicide which led to the introduction of legislation such as the Domestic Violence Amendment Act 14 of 2022, the Criminal and Related Matters Amendment Act 12 of 2022, and The Criminal Law (Sexual Offences and Related Matters) Amendment Act 13 of 2022. , Thesis (MA) -- Faculty of Humanities, Political and International Studies, 2025

- Description: Womanhood rites of passage fulfill the purpose of integrating young girls into accepted womanhood roles, ideals, definitions, and expectations. Traditional Basotho womanhood rites of passage have become less popular in the modern context, with alternative womanhood practices and spaces populating the contemporary Basotho context. Through a qualitative methodology, this study explores three Basotho womanhood spaces insofar as they define and construct womanhood for the participants. Additionally, this thesis critically explores the personal experiences of the shifting womanhoods practices and values between the traditional and contemporary contexts of the Basotho women. It draws on the in-depth accounts of nine women of different ages and backgrounds and participating or having participated in one of three womanhood spaces: Lebollo la basali, Pitiki ea bomme, and Makoti. This study leans on African Feminist theory to engage these experiences and further relies on the qualitative methodology, using semi-structured interviews to collect data. , Thesis (MSocSci) -- Faculty of Humanities, Sociology, 2025

- Description: Introduction: Substance abuse, particularly alcohol abuse, has been widely studied. Due to its nature as a legal substance, the negative effects of alcohol are seemingly undermined. However, studies over time have constantly shown that despite being legal, alcohol has detrimental effects that should not be ignored. The consequences of alcohol can be divided into two broad categories: short-term and long-term. Short-term effects include blackouts, poor decision-making, engaging in unsafe sexual practices, and vandalism. On the other end, long-term effects include physiological harm and declining neurocognitive capacity. These and many other forms of harm have been studied, mainly in diagnosed alcoholic populations. Overtime, the population of interest in terms of alcohol-related harm broadened and it increasingly became evident that university students are susceptible to alcohol-related harm and alcohol use disorders due to their drinking patterns. Student drinking patterns involving binge drinking, pre-drinking, and drinking games are common due to the fact that in university, young adults have less supervision and more freedom. University students are also in an environment where excessive alcohol use is normalised, which makes them prone to alcohol-harm. However, it is important to note that different demographics are predisposed to alcohol-harm differently. Gender, age, racial and socio-economic differences are some factors that have been proven to differentiate individuals’ likelihood of experiencing alcohol-related harm. Unfortunately, the differences across these different demographics within a South African university population are yet to be adequately explored. A large percentage of existing literature on demographic differences in the experience of alcohol harm in university cohorts has been largely amongst Western student populations. Methods: The present longitudinal study aimed to rectify this research gap by providing an evidence-based outcome analysis of demographic differences in the experience of alcohol-related harm in a South African student population. Data were collected using the Alcohol Use Disorders Identification Test (AUDIT) over a three-year period (2015, 2016 & 2017) from the same Rhodes University student cohort. Demographic data in the form of age, race, gender, and socio-economic status was analysed to study alcohol-related harm. Results: Data indicated that male students did not significantly experience greater alcohol-related harm compared to female students (p > 0.05). Similarly, white students did not experience significantly more alcohol-related harm compared to non-white students (p > 0.05). Findings further indicated that younger students experienced significantly greater alcohol-related harm in comparison to older students (p < 0.05). Lastly, students from a higher socio-economic background did not experience significantly greater alcohol-induced harm when compared to those from a lower socioeconomic status background (p > 0.05). Conclusion: Differences by age could be related to early brain development being linked to greater risk-taking, resulting in greater alcohol-related harm. Moreover, the absence of guardians may place younger student populations at greater risk for unhealthy drinking patterns, which may result in alcohol-related harm. Findings from the study suggest a greater need for interventions to target younger student populations. Future studies should explore why younger students are at greater risk for alcohol-related harm and seek to develop interventions that are more effective for this population. , Thesis (MSocSci) -- Faculty of Humanities, Psychology, 2025

- Description: Namibia has decided to use English as the transitional language and medium of instruction for Grade 4, even though learners have been performing poorly in English Second Language (ESL). Despite various interventions being recommended to address this issue, there has been little success. One teaching approach that experienced ESL teachers may use to enhance reading comprehension is pedagogical translanguaging. However, there is a lack of research exploring the use of this approach in Namibian primary schools, particularly in Grade 4. To address this gap, this study was conducted to investigate the pedagogical translanguaging practices employed by Grade 4 ESL primary school teachers in Namibia to improve reading comprehension. A qualitative exploratory case study oriented to an interpretivist paradigm was conducted. Purposive sampling was used to select five Grade 4 ESL teachers from the Oshikoto region for the study. Data were collected using simulated recall interviews, non-participant observation and document analysis. The data were analysed using an inductive thematic framework. The study showed that using simplified language, gestures, and pictures helped ESL teachers communicate with their learners and improve reading comprehension. The use of visual aids such as picture-rich texts, drawings, sketches and concrete materials (realia) also helped Grade 4 ESL learners in their reading comprehension. This visual support helped in vocabulary acquisition and reinforced the meaning of words through associations with images, leading to a better understanding of the language. The study also found that including drawings and sketches in reading lessons added a layer of pedagogical depth that aligned with learners' cultural backgrounds. This helped teachers to engage with their learners more deeply and promoted a sense of cultural inclusivity in the ESL classroom. The study found that teachers use Oshindonga, the learners’ mother tongue, to communicate with those who struggle with English or find it challenging to understand ESL texts. The study revealed that when teachers encouraged learners to use their mother tongue, they became more active and asked questions for clarity. Moreover, the study revealed that code-switching and language brokering, where Grade 4 emergent ESL learners and the ESL teacher translate or interpret using both the learners' native language and ESL, helped increase learner engagement and comprehension. The findings suggest that using translanguaging practices can enhance comprehension, support learners with special needs and assist in the overall learning and understanding of ESL. Furthermore, the study concluded that Grade 4 ESL teachers employ translanguaging procedures in an unplanned manner, perceiving the use of the mother tongue as a spontaneous action carried out when circumstances require it. This study recommends incorporating translanguaging into the official language policy and the National Curriculum for Basic Education as a means of instruction in ESL classrooms. This official endorsement would guarantee the integration of translanguaging across schools and support consistent language learning. The formalisation and endorsement of translanguaging in the official language policy would prove its success and encourage ESL teachers to utilise it. , Thesis (MEd) -- Faculty of Education, Secondary and Post School Education, 2025

- Description: Global change is accelerating habitat degradation and extinction rates, disproportionately affecting freshwater ecosystems. Biological invasions, a core component of global change, have been recognized as a major driver of this phenomenon. Invasive alien aquatic plants (IAAPs) are a prime example, disrupting ecological dynamics and hindering the economic and social activities that depend upon freshwater ecosystems. The best approach to managing IAAPs is preventing their introduction and taking swift action when infestations are detected. Unfortunately, most IAAPs are only recognized after they have spread, making eradication difficult and requiring expensive, ongoing management through manual, mechanical, or chemical means, which become less effective as infestations grow. In this regard, a sustainable alternative against IAAPs is provided by classical biological control. This method lays on the assumption that invasive species have been introduced in an environment which is free from their natural enemies, and that such release allowed them to redirect their resources towards growth and reproduction. Accordingly, weed biocontrol involves introducing one such enemy - a so-called biocontrol agent - to regulate the population of the plant, ideally reducing its density below a critical threshold, minimizing its impacts. Biocontrol programs must follow stringent protocols in order to a) ensure the selection of the most appropriate agents; b) guarantee their establishment and effectiveness in controlling their target; c) minimize the risks involved with their release; and d) monitor their impacts after they have been released. This thesis is composed of two parts, focusing on pre-release studies (Part I, Chapters 1-4) and post-release evaluations (Part II, Chapter 5), respectively. Part I explores the biological control of Iris pseudacorus L. (Iridaceae) – yellow flag – a Eurasian plant that has invaded temperate wetlands worldwide. The first step consisted of conducting field surveys across the native range of the weed, which led to the selection of three candidate biocontrol agents. As a second step, bioclimatic niche modelling was used to forecast the current and future suitability of the weed and its prospective agents. These models helped to identify areas most at risk of invasion and predict how climate change might affect biocontrol efficacy, showing differing impacts in the Northern and Southern Hemispheres. Further, a scoring system was developed to prioritize non-target plants for host-specificity testing, focusing on species within the family Iridaceae. Most taxa prioritized are native to the Americas, South Africa and eastern Asia, highlighting the importance of collaboration across regions when dealing with global invaders with complex phylogeographic distributions. Finally, a germination study confirmed that I. pseudacorus seeds from Argentina germinate more than Belgian seeds, especially in absence of cold stratification, suggesting increased performances of invasive populations and an adaptation to warmer temperatures. Nonetheless, impact assessments conducted on one of the three biocontrol agents demonstrated that it could cause juvenile mortality, suggesting it may effectively reduce seedling recruitment, though further research on agents targeting reproductive structures is recommended. Part II of the thesis addresses an often understudied aspect of post-release evaluations: ecosystem recovery following biological control. To do so, a case study is presented, investigating the biological control of water fern, Azolla filiculoides Lamb. (Salviniaceae), in Belgium. The results of this study are used to discuss the shortcomings of different experimental designs, the lack of baseline data in invasion ecology, and the intricacies of defining and quantifying ecosystem recovery in light of legacy effects and context-dependency. , Wereldwijde verandering versnelt de degradatie van habitats en de uitstervingscijfers, met een onevenredige impact op zoetwaterecosystemen. Biologische invasies, een kernonderdeel van klimaatverandering, worden erkend als een belangrijke drijvende kracht achter dit fenomeen. Invasieve uitheemse waterplanten (IAAPs) zijn een duidelijk voorbeeld, omdat ze ecologische dynamiek verstoren en economische en sociale activiteiten belemmeren die afhankelijk zijn van zoetwaterecosystemen. De beste aanpak voor het beheer van IAAPs is het voorkomen van hun introductie en het nemen van snelle maatregelen bij het detecteren van besmettingen. Helaas worden de meeste IAAPs pas herkend nadat ze zich hebben verspreid, wat uitroeiing moeilijk maakt en dure, voortdurende beheersing vereist door handmatige, mechanische of chemische middelen, die minder effectief worden naarmate besmettingen toenemen. In dit opzicht biedt klassieke biologische bestrijding een duurzaam alternatief tegen IAAPs. Deze methode berust op de veronderstelling dat invasieve soorten zijn geïntroduceerd in een omgeving die vrij is van hun natuurlijke vijanden, waardoor ze hun middelen konden richten op groei en reproductie. Bijgevolg omvat onkruidbestrijding het introduceren van een dergelijke vijand - een zogenaamde biocontrole-agent - om de populatie van de plant te reguleren, idealiter door de dichtheid ervan onder een kritische drempel te verlagen en zo de impact ervan te minimaliseren. Biocontroleprogramma's moeten strikte protocollen volgen om a) de selectie van de meest geschikte agens te waarborgen; b) hun vestiging en effectiviteit bij het beheersen van hun doel te garanderen; c) de risico's van hun vrijlating te minimaliseren; en d) hun impact na vrijlating te monitoren. Dit proefschrift bestaat uit twee delen, gericht op respectievelijk pre-release studies (Deel I, Hoofdstukken 1-4) en post-release evaluaties (Deel II, Hoofdstuk 5). Deel I onderzoekt de biologische bestrijding van Iris pseudacorus L. (Iridaceae) - gele lis - een Euraziatische plant die gematigde moeraslanden wereldwijd heeft gekoloniseerd. De eerste stap bestond uit het uitvoeren van veldonderzoeken in het inheemse verspreidingsgebied van het onkruid, wat leidde tot de selectie van drie kandidaat-biocontroleagenten. Als tweede stap werd bioklimatisch nis-modelleren gebruikt om de huidige en toekomstige geschiktheid van het onkruid en zijn potentiële agens te voorspellen. Deze modellen hielpen gebieden met het grootste risico op invasie te identificeren en voorspelden hoe klimaatverandering de effectiviteit van biocontrole zou kunnen beïnvloeden, met verschillende effecten op het noordelijk en zuidelijk halfrond. Daarnaast werd een scoresysteem ontwikkeld om niet-doelplanten te prioriteren voor host-specifieke tests, met de nadruk op soorten binnen de familie Iridaceae. De prioritaire taxa zijn inheems in Amerika, Zuid-Afrika en Oost-Azië, wat het belang van samenwerking tussen regio’s onderstreept bij het omgaan met mondiale invasieve soorten met complexe fylogeografische verspreiding. Ten slotte bevestigde een kiemingsstudie dat I. pseudacorus zaden uit Argentinië meer kiemen dan Belgische zaden, vooral bij afwezigheid van koude stratificatie, wat wijst op verhoogde prestaties van invasieve populaties en aanpassing aan warmere temperaturen. Nochtans toonden effectbeoordelingen van een van de drie biocontroleagens aan dat deze de mortaliteit van juvenielen kon veroorzaken, wat suggereert dat het effectief kan zijn bij het verminderen van de zaailingrekrutering. Toch wordt verder onderzoek naar agenten die zich richten op reproductieve structuren aanbevolen. Deel II van het proefschrift behandelt een vaak onderbelicht aspect van post-release evaluaties: ecosysteemherstel na biologische bestrijding. Om dit te realiseren wordt een casestudy aangeboden over de biologische bestrijding van watervaren, Azolla filiculoides Lamb. (Salviniaceae), in België. De resultaten van deze studie worden gebruikt voor de bespreking van de tekortkomingen van verschillende experimentele ontwerpen, het gebrek aan basisgegevens in invasie-ecologie en de complexiteit van het definiëren en kwantificeren van ecosysteemherstel in het licht van nalatenschapseffecten en contextafhankelijkheid. , Thesis (PhD) -- Faculty of Science, Zoology and Entomology, 2025

- Description: Pharmacogenomics, the foundation of personalized medicine distinguishes patients into different categories based on their response to the risk of a disease. Cytochrome P450 (CYPs) proteins are a family of enzymes critical in the metabolism of drugs and other substances. Genetic polymorphisms in CYPs can result in different enzymatic activity in individuals influencing the efficacy and toxicity of drugs. One of the CYPs which primarily metabolizes nicotine and other pharmaceutical drugs such as Artemisinin and Artesunate, Pilocarpine, Valproic Acid and Letrozole is CYP2A6. The gene encoding the protein is highly polymorphic and this can affect the rate of metabolism of drugs in individuals. Previously most studies unveiled connections between CYP2A6 variants and nicotine. Implications concerning the effects of specific missense variations in CYP2A6 drug metabolism have deficiencies. This study aimed to critically examine the structural and functional implications of 13 CYP2A6 allele variations on CYP2A6 protein using Bioinformatics techniques. Methods used were template selection, mutagenesis, parameter assignment and protonation. Molecular Dynamics to get insights regarding protein behavior at an atomic level, clustering to identify conformations during a simulation and DSSP for secondary structure analysis to monitor how secondary structures evolve. Berendsen and Parinello-Rahman barostats at production run were used for comparison. A global analysis was conducted to identify structural transitions (RMSD, RMSF, and Rg), clustering, and secondary structure prediction. Results from Berendsen barostat were inconsistent compared to Parrinello-Rahman barostat implying that CYP2A6 is sensitive to the pressure coupling parameter for precise and accurate results. Our clustering results showed each system in one conformation, fluctuations and shifts on the C-D, H-I loops and F, G, and L helices on variants I149M, F118l, K476R, and E390K_N418D_E419D. This indicated a potential loss of function limiting the protein’s ability to conformational flexibility for catalysis and substrate recognition. Certain regions of CYP2A6 became more rigid due to variations, which could have a negative impact on the catalytic activity, regulatory interactions, and general function of the enzyme in metabolism. Globally the variations did not cause large changes to the protein, there is need for a local analysis using Dynamic Residue Networks to study how residue interactions affect the function of CYP2A6. , Thesis (MSc) -- Faculty of Science, Biochemistry, Microbiology and Bioinformatics, 2025

- Description: With increasing urbanisation and corresponding environmental impacts, urban green infrastructure (UGI) and the services it provides are of high importance. However, the degree to which these spaces are beneficial and provide ecological services are influenced by the extent to which patches of UGI are connected to each other. Varying levels of connectivity may enhance or lower the resilience of the UGI and the biodiversity it houses. Although not considered as UGI, golf courses are prominent green spaces in many urban landscapes occupying vast areas of land, and therefore hold potential to aid biodiversity and facilitate species movement. However, the extent which golf courses are able to do so is a function of both the structure and availability of resources on the golf courses, as well as in the surroundings areas or landscape in which they are situated. This notion of connectivity of golf courses to their surroundings UGI (in its many forms) and landscapes has not been adequately explored in the literature as much of the present literature has addressed golf courses’ biodiversity in isolation of other UGI, or where it has been considered, only the context in which golf courses were situated has been acknowledged (i.e. urban or rural landscapes). Moreover, as golf courses occupy large areas of lands forms of UGI, they may also be able to enhance the connectivity of the landscapes in which they are situated through increasing land cover, and lowering fragmentation through connecting patches. This however, is also context specific, as seen in natural settings were golf courses would in fact fragment the landscape. This study therefore sought to assess the extent to which urban golf courses are connected to other forms of UGI in the South African context, and illustrate the importance of paying attention to connectivity in an avifaunal diversity study. It also aimed to investigate the potential of urban golf courses to foster avifaunal diversity in comparison to a reference landscape, the direct surrounding urban and residential areas. To analyse the extent to which golf courses in three South African cities were connected to the wider landscape a connectivity analysis was undertaken using GIS software. This analysis indicated that all golf courses were to some extent connected to a range of different UGI. Whilst the level of connectivity fluctuated between golf courses and cities, there was however no significant difference noted. Urban golf courses in the South African context are thus not isolated habitats but connected to other land uses and therefore potentially provide valuable resources that aid biodiversity. Despite being physically connected to surrounding UGI illustrating that both the golf courses benefit from the surrounding UGI and vice versa, at a larger landscape there was not sufficient evidence of the ability of golf courses to enhance connectivity. Although there was little evidence of golf courses’ ability to aid connectivity at the larger landscape scale, the observed extent to which golf courses were connected to their directly surrounding landscape and the high presence UGI within the larger landscape, informed the more refined investigation of avian biodiversity of golf courses in comparison to surrounding urban areas in the city of Cape Town. This biodiversity analysis indicated that there was significantly higher bird diversity on golf courses in comparison to the surrounding urban areas. However, the high level of connectivity to directly surrounding UGI that was obtained in the former part of the study proved to have no impact on the diversity noted. In contrast, the connectivity at the landscape scale, a scale addressing the broader landscape, provided valuable insight into factors determining the levels of avifaunal diversity noted. This dissertation therefore provides evidence of the biodiversity supporting function of urban golf courses and highlights the importance of landscape context in ecological assessment. These findings are a starting point for future research about the capacity of golf courses to support biodiversity in conjunction with other UGI. In the Global South context, which is complex and dynamic in nature, this information is vital, as these dynamic and changing landscapes provide opportunities to incorporate, and preserve already existing biodiversity. , Thesis (MSc) -- Faculty of Science, Environmental Science, 2025

- Description: Rhodes University Honorary Doctorate Citation (5 April 2024) Tandabantu Tennyson August: 1980s. South Africa. In the Bantustans of the time, like the Transkei, the youth have little reason for hope. They have much reason for despair. Their choices seem limited to the politics of struggle or to crime, an attempt to gain some kind of advantage from the meagre and unacceptable options on offer. In those bleak times, what was needed was visionaries. People who could see beyond the current circumstances to a different future and imagine how best to prepare for it. Not as idealists, but as pragmatists. What would happen once circumstances change, once the struggle had succeeded? Would we be ready for it? What qualities would the youth need to have in order to both benefit from and participate in a new dispensation? One such visionary was Tandabantu Tennyson August, and it is my distinct pleasure to have the opportunity to tell you more about him. Born in 1948, Mr. August matriculated from Healdtown High School, before pursuing higher education at the University of Transkei, where obtained a Bachelor of Arts degree majoring in English and Geography. This was followed by Comparative Curriculum Studies at the University of South Africa, alongside obtaining teaching certificates from Lovedale and Cicira teacher training colleges, with majors in Physical Science, Mathematics, Science, and Mathematics. This solid educational foundation laid the groundwork for his impactful career in education. He taught at Wongalethu High, St Johns College and was deputy principal at Norwood, before taking up his first principalship, at Thanga High School in 1980. From 1984 to 1990 he was principal of Ndamase High School. During his tenure there, the matric pass rate never fell below 90%. From 1991 to 1995 he was principal Isivivane High School during which time the school was promoted from a primary to a high school. Following his distinguished service at schools, he worked at the Eastern Cape Department of Basic Education, first as a deputy chief education specialist (1996 – 2006) and then as chief education specialist (2006-2010). During that time, he played a pivotal role in establishing (in conjunction with Rhodes University) and being the provincial coordinator the Advanced Certificate in Education in English, followed by ACEs in mathematical literacy and life orientation. In 2016 he received a provincial teaching award for excellence. In 2017 he was awarded the Kade Asmal award for excellence in teaching. To this day, he remains an Executive member of the eastern cape Education advisory council. Quite a career. But there’s something I haven’t mentioned. He was also an accomplished rugby player of international standing. While at Lovedale College, he was selected to represent Border and then the South African African Rugby Board, playing England in Gqeberha in 1972, in a team that would later be known as the black springboks. He eventually received his green and gold springbok blazer as just recognition of his achievement. He incorporated his love of sport into his vision for the youth under his care, as part of his overriding mission of educating the whole person. He got everyone involved in sport, if not as a player, then as a supporter. Especially during his time as principal of Ndamase High School, I am led to believe, it was extremely intimidating for opposing teams to play them. Not only at Ndamase home games, but especially at their away games. There would be one bus for the team players, and six buses for the supporters. From 1986 – 1990: he was president of the Transkei schools` sports union (TSSU). But there’s yet another thing I haven’t mentioned. In 1981, just as his career as an educational leader was really taking off, he was involved in a terrible motor vehicle accident. It left him permanently disabled and, for much of his life, a wheelchair user. Rather than stopping him, it simply added another string to his bow, now as an advocate for the disabled. From 2012 – 2022: Chairperson Eastern Cape South African National Association For Special Education (SANASE): this organization cater for the education and wellbeing of learners with disabilities and special needs. In 2023, he was the national deputy president of the same organisation. From 2013 – to date: he is a Board Member on the National Council of & for persons with disabilities (NCPD). I had the pleasure of an extensive conversation with one of Mr August’s former pupils at Ndamase High, Professor Deyi Mbelani, the current director of Rhodes University’s Institute for the Study of Englishes in Africa. He told me many stories about Mr August’s leadership, that I only wish I had time to share with you now. I put it to Professor Mbelani that, having read about Mr August, the word that stood out for me was “dedication.” He agreed that “dedication” was the word, but that I must not leave out another: “vision”. It is Mr August’s status as a visionary that best defines him, he said. Going back over the above, I think he is right. Mr Chancellor I have the honour to request you to confer the degree of Doctor of Laws honoris causa on the Mr Tandabantu Tennyson August. *The above citation draws heavily on documents submitted as part of the honorary doctorate nomination process and others compiled by the Division of Communications and Advancement. - Tom Martin.

- Description: Rhodes University Honorary Doctorate Citation (5 April 2024) Tandabantu Tennyson August: 1980s. South Africa. In the Bantustans of the time, like the Transkei, the youth have little reason for hope. They have much reason for despair. Their choices seem limited to the politics of struggle or to crime, an attempt to gain some kind of advantage from the meagre and unacceptable options on offer. In those bleak times, what was needed was visionaries. People who could see beyond the current circumstances to a different future and imagine how best to prepare for it. Not as idealists, but as pragmatists. What would happen once circumstances change, once the struggle had succeeded? Would we be ready for it? What qualities would the youth need to have in order to both benefit from and participate in a new dispensation? One such visionary was Tandabantu Tennyson August, and it is my distinct pleasure to have the opportunity to tell you more about him. Born in 1948, Mr. August matriculated from Healdtown High School, before pursuing higher education at the University of Transkei, where obtained a Bachelor of Arts degree majoring in English and Geography. This was followed by Comparative Curriculum Studies at the University of South Africa, alongside obtaining teaching certificates from Lovedale and Cicira teacher training colleges, with majors in Physical Science, Mathematics, Science, and Mathematics. This solid educational foundation laid the groundwork for his impactful career in education.

A conspiracy of silence: the authorial potential of full masks in performer training, dramaturgy and audience perception in South African visual theatre

- Description: Silent Mask Theatre in South Africa has the potential to cut across linguistic divides and deliver a product that offers an intimate, unique experience for the audience as well as the actor. South Africa not only has a complicated history, but also 11 languages (12 if one counts South African Sign Language – SASL -, which still holds a curious position of being counted official or not), and the one that theatre-makers choose to present in gives a certain “authority” to the production. Silent masks remove the need for linguistic understanding, something necessary for more abstract thought, and focusses instead on the emotional relevance and interplay between characters. In doing so, it proves an important way to create relevance for an audience, creating a delicate dance between the Mask (character and thereby text), how the actor plays it, and then the closing of meaning through the audience experience. Thus, is created a trialogue between these elements that gives the production the opportunity to speak to the hearts and minds of the audience. Globally, the study of silent character masks is still relatively new, with proponents of it only coming to the fore in the past few years (Wilsher, 2007). Mask Theatre has grown exponentially in the UK and Europe with companies like Vamos Theatre, exploring PTSD in works like A Brave Face (2018) or death in Dead Good (2021), and Familie Flöz either on the more whimsical side like Hotel Paradiso (2011) or the more hard-hitting Infinito (2006), gaining popularity and exposure. In South Africa, there is strangely not an indigenous tradition of masks, as opposed to other parts of Africa. This is fascinating, and probably points towards a more “oral tradition” of South Africa/Africa. However, the author aims to point out the ways that the silent mask entered South African consciousness at a time where more attention was being paid to “performing objects” (Proschan, 1985), and particularly in Cape Town with the advent of the Out the Box Festival. This thesis aims to contextualise Visual Theatre and Mask Theatre in a South African context, seeing within it a movement towards a more global perspective of puppetry, material performances, and performing objects. Although “ghettoised” for a long time (Taylor, 2004), performing objects emerged and became a leading case for the primal “text” of a performance. Handspring Puppet Company, Janni Younge, and the author’s company, FTH:K, became primary grounds of contestation against more conventional, text-based theatre. Starting with a reflective account of the author’s journey towards masks, the thesis branches out into a reflection on its author’s pedagogical praxis, and how silent masks work, before critically reflecting on and analysing his key works, such as Pictures of You (2008-2013), which deals with home invasions and grief, and Benchmarks (2011), which deals with the wave of xenophobia that hit South Africa around that time. . This were built from the ground up, working with current issues both in the author’s, and the country’s, mileau. In the last two decades, performing object work in South Africa has begun to flourish. This is the first thesis to investigate mask work in the country during this period. Its possibilities for Screen and Stage Acting are still being explored. , Thesis (PhD) -- Faculty of Humanities, Drama, 2024

- Description: Praying mantises (Dictyoptera: Mantodea) are an iconic group of predatory insects, comprising around 2500 species globally, that occur in all zoogeographic regions except the poles. Their presence in the social psyche of many cultures has existed for millennia, but until the past decade, Mantodea has received little attention from the scientific community as the constituent species are of little economic or medical importance. Africa is rich in praying mantis diversity, accounting for approximately 45% of all described species, yet it remains largely under-sampled compared to the New World and Asian regions. Recent exploration of Gabon and Central African Republic have proved fruitful, with new species descriptions being major highlights. A recent re-cataloguing of southern African praying mantises has proved useful as specimen identifications were checked, new distributions were recorded, and most importantly, it was revealed that museum collections have significantly more diversity than previously recorded. A meta-analysis of African praying mantises was conducted; we present a species checklist to the countries of Africa, including Madagascar and surrounding islands. Currently, 17 families, 182 genera, and 1104 species occur in Africa.Historically, the classification of praying mantises was based solely on morphological features, and the novelty of the field at the time made it unclear which characteristics were of taxonomic importance. The onset of molecular systematics brought attention to incongruences between morphological and molecular phylogenies, believed to be attributed to convergent evolution masking the underlying evolutionary processes that occurred. Significant progress has been made in the past two decades regarding Mantodean classification and most described genera have their phylogenetic position. With the addition of more African taxa, we present mantodean phylogenies for molecular and morphological data. Molecular phylogenies were estimated through Bayesian Inference and Maximum Likelihood analyses using two nuclear (28S and H3) and two mitochondrial markers (16S and COI) for 210 individuals that represented 24 of the 29 families globally. Morphological phylogenies were estimated through Maximum Likelihood analyses of a morphological data matrix comprising 149 characters for 248 individuals that represent 24 families. The same data matrix was used to produce a key to all African mantodean families, accompanied by their descriptions. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2024

- Description: South Africa is faced with a national water security challenge that is increasingly worsening due to a myriad of structural and governance factors. Over the past few years, several municipalities across the country have experience temporary loss of water access, while some have come dangerously close to Day Zero – a day when water levels of the major dams supplying water to residents would become critically low, resulting in households having no running water. But for the people of the township of Hammanskraal in the City of Tshwane metropolitan municipality, water insecurity has reached crisis point. Since 2005, the township has been battling with a chronic lack of access to safe drinking water. The water quality in Hammanskraal has been so dire that in 2019, the South African Human Rights Commission declared it unfit for human consumption and deemed it a violation of human rights. Despite this, the crisis has persisted. In 2023, Hammanskraal became the epicentre of a cholera outbreak that claimed a number of lives in several provinces across the country. Using a qualitative approach, this study analyses the equity dimensions and governance drivers of water security challenges in Hammanskraal. Through interviews with residents in Hammanskraal and government officials in the City of Tshwane metropolitan municipality and the Gauteng Provincial Government, the study explores the lived experiences of those affected by the water insecurity, as well as the governance drivers that inform the crisis. The study, using water justice theory and conflict theory/Marxism, contends that the water security challenges in Hammanskraal are driven by physical, economic and political factors. These factors have their roots in the geo-history of the township as well as contemporary responses to spatial development and water resource management by the post-apartheid government. The study finds that there are equity dimensions to the water security challenges in Hammanskraal. Contextually, the legacy of apartheid’s policy of separate and uneven development, coupled with contemporary failings of the implementation of the National Water Act, impact water access. In terms of water governance, while factors such as climate change and urbanisation are contributing determinants, the water security challenges in Hammanskraal are fundamentally the result of institutional failings that include lack of planning and investment as well as lack of infrastructure maintenance. The implications for South Africa in general is that failure to resolve water inequities and to strengthen water governance will result in the reproduction and persistence of structural inequalities. Key recommendations of the study include the expansion of the Temba Water Purification Plant, strengthening and coordination of institutions for water security, the setting of water allocation ceilings in Gauteng municipalities and investment in alternative water sources and tools for water conservation. The study also recommends further study into the extent to which water security challenges impact social unrest in South Africa. , Thesis (MSc) -- Faculty of Science, Institute for Water Research, 2024

- Description: The concept of care is proposed as an ethical and practical framework for the reading of the artistic and writing practices of Georgina Maxim, Kresiah Mukwazhi, Gladys Kalichini, Léonard Pongo and Masimba Hwati. In their practices, dissent is both an existential crisis and a constitutive practice. Through small actions, they offer up new narratives. The notion of seeing care as a form of dissent is to simply reflect on the artistic practices that are integrated with or responsive to forms of political protest and dissent based on ethical care practices and what it means to align with those things that matter to us and distancing ourselves from those things that do not. The thesis explores the ethic of care, its possibilities as a dissenting approach, and provides a narrative description of five case studies that exhibit different expressions of care in contemporary art. By prioritising care, there is an educational interest in creating resources and themes for a politically engaged approach to artistic practice and the creation of art. This study also aims to shed light on the power of art as a tool for social and political commentary, and the role of artists as agents of change in society. The study focuses on how these artists use their art to challenge societal norms and political structures, embodying the concept of care as a form of resistance. It underscores the importance of understanding the context in which art is created and the messages it conveys, particularly in societies where freedom of expression may be constrained. The study further investigates how these elements are presented in different ways to show the different manifestations of care and dissent. Through semi-structured interviews, analysis of relevant texts, and a detailed visual analysis of selected works from the five artists, the situational approach was used to explore how meanings are negotiated. The outcome is an expanded proposal for care as dissent and a listening guide as a tool or approach in helping us to listen to marginalised voices, validate experiences, identify barriers and building empathy. , Thesis (MA) -- Faculty of Humanities, Fine Art, 2024

The study focuses on how these artists use their art to challenge societal norms and political structures, embodying the concept of care as a form of resistance. It underscores the importance of understanding the context in which art is created and the messages it conveys, particularly in societies where freedom of expression may be constrained. The study further investigates how these elements are presented in different ways to show the different manifestations of care and dissent. Through semi-structured interviews, analysis of relevant texts, and a detailed visual analysis of selected works from the five artists, the situational approach was used to explore how meanings are negotiated. The outcome is an expanded proposal for care as dissent and a listening guide as a tool or approach in helping us to listen to marginalised voices, validate experiences, identify barriers and building empathy. , Thesis (MA) -- Faculty of Humanities, Fine Art, 2024

- Description: Co-management of protected areas (PAs) is a desired conservation approach aimed at balancing ecological goals and livelihood needs. Central to co-management are issues related to power sharing, responsibilities and benefit sharing. However, there still remains a dominance of an ecological emphasis in PA management, with studies focusing more on ‘objective’ biodiversity indicators for measuring the effectiveness of protected areas. However, focusing only on ecological indicators addresses a narrow perspective of achieving ecological integrity and misses social dimensions that, in some cases, might be considered more important than technical considerations. Particularly, in contexts with a history of socio-physical displacement of Indigenous people and local communities (IPLC), the social dimensions of wellbeing are complexly embedded into the economic and ecological dimensions, such that ignoring these linkages might jeopardise the success of protected areas. Thus, the aim of this study was to examine the state of research and conceptual advances on social indicators of conservation success in co-managed PAs and stakeholder views and perceptions on socially just conservation in co-managed protected areas in Silaka and Hluleka Nature Reserves, South Africa. To achieve this, a scoping review, semi-structured interviews and futures workshops (using the three horizons framework) were conducted. Findings from the scoping review (chapter 2) revealed that much of the reported social monitoring indicators still rely on quantifiable metrics (i.e., economic benefits) and less on subjective and relational metrics (i.e., qualitative strength of social networks and perceptions). Unsurprisingly, many of the reviewed case studies revealed the use of participation as an indicator of evaluating co-management success. Further, the interviews and futures workshop results in chapter 3 showed that the non-accrual of key co-management expectations such as the employment of local people, benefit-sharing (material or otherwise), participation in decision-making and community development has led to heightened conflicts between the reserve management agency and local people. Consequently, the respondents did not value the co-management arrangements, citing unfulfilled promises. Broadly, the findings of this study emphasise the need for collective and collaborative efforts in developing indicators that are not only socially just but those that are context dependent and sensitive. , Thesis (MSc) -- Faculty of Science, Environmental Science, 2024

- Description: This thesis explores students’ experiences in the Faculty of Humanities at Rhodes University, specifically focusing on their perspectives on decolonization. The thesis has two central aims: first, to investigate the students’ general understanding of decolonizing the curriculum and second, to examine their experiences within the Humanities Faculty and their perception of how decolonized the faculty is. Through in-depth interviews with students in the faculty, the study aimed to answer questions regarding students’ thoughts on the decolonization of university curricula and their experiences within the Faculty of Humanities at Rhodes University. The findings reveal diverse student views on decolonization, with definitions of decolonization provided by students touching on topics such as the Africanization or Indigenization of the curriculum, systemic transformation, the importance of unlearning colonial ideologies and the relationship between language and decolonization. The students’ perceptions of the level of decolonization they witness in the faculty are categorized along three lines: the views of those who believe the departments they interact with are decolonized, the views of those who think efforts are being made but more progress is needed, and those who see no evidence of decolonization. The thesis highlights that while some students believe that positive steps towards decolonization are being taken, others express scepticism and call for a more diverse representation of scholars and scholarship and a departure from traditional Eurocentric approaches. , Thesis (MA) -- Faculty of Humanities, Political and International Studies, 2024
