Description: The Namibian Science curriculum acknowledges that indigenous knowledge (IK) is an important basis for learning science. Among the shared reasons is that it provides learners with access to abstract scientific concepts. As a result, teachers are encouraged to integrate IK into the teaching and learning of science. However, it seems that there are no explicit guidelines on how IK should be integrated into science classrooms. It is against this backdrop that this study sought to explore how the indigenous technology of making oshikundu (a non-alcoholic beverage) can be mobilised by Grade 8 Life Science teachers to mediate learning of diffusion in their classrooms. The study was underpinned by interpretive and indigenous research paradigms. Within these paradigms, a qualitative case study approach was employed. Four Grade 8 Life Science teachers from four different schools in Okahandja town, Otjozondjupa Region, Namibia, participated in this study. Additionally, an expert community member who was knowledgeable about the indigenous technology of making oshikundu was requested to demonstrate how to make it. In this event, the Life Science teachers had to identify the science concepts embedded in the practice. To gather data, this study made use of semi-structured interviews, workshop discussions, observations and journal reflections. Vygotsky’s sociocultural theory was used as a theoretical framework and Mavhunga and Rollnick’s topic-specific pedagogical content knowledge (TSPCK) was used as an analytical framework. The findings of this study revealed that the teachers’ understanding was positively influenced by the integration of IK which certainly assisted them to relate better to the concept of diffusion. This was validated when teachers extracted emerging science concepts from the indigenous technology of making oshikundu. The implication of this study is that expert community member presentations can greatly enhance sense making of science concepts. The study thus recommends that school-based teachers’ continuing professional development in collaboration with expert community members should be carried out to enhance both the teachers’ subject content knowledge and pedagogical content knowledge on IK integration. , Thesis (MEd) -- Faculty of Education, Secondary and Post-School Education, 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

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: Knowledge-making in universities is not neutral and takes different forms. This thesis critically examines the politics of knowledge to propose and present a transgressive schema for knowledge-making that is co-created with students. It emerges from teaching and learning encounters in the Humanities Extended Studies (ES) Programme at Rhodes University, where for the past decade we have experimented with different ways of knowledge-making that run counter to conventional pedagogic practices. We set up a project for the thesis that allowed us to work with knowledge in ways that are Afrocentric, and that hold and nurture our dreams. The theory and methodology of the project are explained in the first academic paper for this PhD by publication. The project and its derivatives use an African Feminist framing, and centre the ontoepistemologies of African young people who find themselves alienated and marginalised by a western bias in university curricula. Former ES student volunteers came up with topics, responded to them, reviewed each other’s work, and co-wrote two academic papers that demonstrate a praxis of African Feminist research and pedagogic principles. Two further projects practise the principles that emerge from the primary project, and together they have tested knowledge-making cultures that inspire critical thinking and creative humanity. These are explained in two further academic papers. One is co-written with the copresenter of an online inter-continental short course for PhD students on African Feminist Research Methodology. The other is single authored, and introduces the third project, a Political and International Studies third-year course on African Feminist theory. The schema for knowledge-making uses the hand, which holds our dream, as a descriptive metaphor. Each of the five fingers of the hand represents an aspect of how we have collaborated on the projects and in lecture rooms, and what this has taught us about how to nurture and inspire the dreams of young African people through transgressive knowledgemaking cultures. The five aspects – framing, activating, seeing, creating, imagining – are mutually constitutive elements of knowledge-making that are introduced throughout the thesis, and explained in careful detail in the conclusion as a synthesis of the collaborations. , Siphethe amaphupha ezandleni zethu: ukwenza iinckubeko zolwazi ezigxile ekuphazamiseni isiqhelo Isishwankathelo Ukwenziwa kolwazi kwiiunivesithi asiyonto engathathi cala kwaye yenzeka ngeendlelangeendlela.

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

“Rwanda cannot be exorcised”: representations of the trauma of the Rwandan Genocide in selected films and novels

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

Description: Non-profit organisations (NPOs) contribute to our society by addressing needs through value-creation activities which are normally not addressed by normal for-profit organisations. These NPOs generate their income through donations, fundraising and market activities such as the sale of products or services. However, in the pursuit of organisational sustainability, these NPOs need to ensure that their income meets their expenditure needs over the long run, to allow continuous value creation and to pursue their mission. An organisation’s business model can be visualised through a business model framework (BMF), which have been illustrated to be useful tools for organisations to test new business models, plan and coordinate activities, and to communicate how an organisations business model works to stakeholders. The use of BMFs by NPOs may be useful for similar purposes. However, a key challenge for NPOs and their management is adapting for-profit tools to be more applicable to the NPO environment. Whilst there has been some progress within the literature on adapting these for-profit business model tools to NPOs, this area of research is relatively underrepresented in the literature. The single case study method, exploratory in nature, following a deductive approach with a theoretical framework was used to evaluate the NPO Business model framework for NPOs with multiple income streams (Sanderse, 2014) appropriateness for the Centre for Biological Control (CBC), a mission-driven research organisation located within Rhodes University. The study made use of an interpretivist paradigm through the lens of resource-based theory. The contextual environment of the CBC was similar to other NPOs in that their organisational sustainability was at risk due to uncertainty about the availability of long-term funding. The CBC is actively diversifying their income streams by establishing new partnerships, which increase the capacity and resource base of the organisation to improve its flexibility in meeting current and potential funders’ needs. The NPO Business model framework for NPOs with multiple income streams was found to be a suitable BMF to visualise the holistic operations of the CBC. However, the role of governance-related matters being represented in this BMF was found to be lacking. An amended framework including governance as part of the Business model framework for NPOs with multiple income streams was developed. This improved the BMF, by allowing for further contextual insight into the CBCs business model as governance played a major role in the key activities and income-generating strategies they participate in. The role a BMF has in assisting an organisation with resource management activities was also explored. A suitable BMF, which allows for a holistic and explicit display of an organisation’s business model, would assist in determining how resources could be better managed or orchestrated to pursue different potential income-generating strategies or improve the efficiency of how resources are used in the current business model. This study contributed to business model theory by further testing the Business model framework for NPOs with multiple income streams as a tool to visualise an NPOs business model and identifying that once the governance block was added, this BMF became more suitable within the CBCs context. A minor contribution to resource based theory was the exploration of the potential roles BMFs play in resource management, which should be further investigated in line with additional research questions proposed. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 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. 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. Case studies are also consulted to provide insight into how to proceed with managing Nymphaea hybrids in South Africa, while the factors governing host specificity and host range expansion are also discussed and considered in the context of B. longulus and M. toddi. Finally, after a consideration of the limitations of these studies, recommendations are made to continue the development of biological control for N. mexicana in South Africa. , Thesis (PhD) -- Faculty of Science, Zoology and Entomology, 2023

Description: This research presents a long-term statistical study of travelling ionospheric disturbances (TIDs) of low- and high-latitude origin over the American and African-European sectors between 2010 and 2018. The TIDs of low latitude origin (hereafter known as poleward TIDs) were studied in both quiet and disturbed conditions, whereas the equatorward TIDs were only studied during quiet conditions. The Kp > 4 and Dst_ -50 nT was used as a criterion for geomagnetic disturbed conditions, while the four geomagnetically quiet days were selected each month based on Kp < 3. Observations of TIDs are made using Global Navigational Satellite Systems (GNSS) total electron content derived data. During quiet conditions, seven and two transhemispheric TIDs were identified over the African-European and American sectors, respectively. The observed TIDs originated from the wintertime hemisphere and propagated into the summertime hemisphere. The horizontal velocity, periods, and horizontal wavelengths of TIDs are in range of cH = 120-274 m/s, 48-80 min and _H = 379-1104 km, respectively. These quiet-time equatorward TIDs have been associated with tertiary gravity waves (GWs) from the dissipation of secondary GWs which are in turn generated from the dissipation of mountain waves (MWs) as a result of excited orographic forcing. The poleward TIDs during geomagnetically quiet conditions over the African and American sectors occur mainly during local daytime. Poleward TIDs were observed mostly in the African-European sector than the American sector. Their horizontal propagation velocities and periods range between 129-280 m/s and 39-70 min over African-European and American sectors. Although the mechanisms responsible for launching quiet-time poleward TIDs have not been established in this study, lower atmospheric processes such as convection systems, sudden stratospheric warming and cold weather fronts may have a role in their generation. During geomagnetic storms in the African sector, almost all poleward TIDs (with the exception of two cases) during the main phase were large-scale with horizontal velocities and periods ranging from 250-503 m/s and 30 min to 2 hours. During recovery phase, poleward TIDs fall under the category of medium scale. In the American sector, the majority of poleward TIDs occurred during the storm's main phase, as opposed to the African-European sector, which experienced a significant number of poleward TIDs during the recovery phase. The periods and horizontal velocities of TIDs range from 45 min-1.5 h and 180-296 m/s during main phase. During the recovery phase, the horizontal velocity and period range from 177-271 m/s and 40-1.5 h, respectively. Overall, it has been shown that statistically, changes in equatorial electrodynamics related to enhanced eastward electric _eld and hence increased equatorial electrojet (vertical E_B drift) correlates highly with the reported poleward TIDs. , Thesis (PhD) -- Faculty of Science, Physics and Electronics, 2023

Description: The research investigated how integrated annual reports (IARs) can enhance the governance of state-owned enterprises (SOEs). Governance of SOEs is crucial to achieving the county’s socio-economic objectives. The SOEs listed on Schedule 2 of the Performance Finance Management Act (PFMA), Act No. No.1 of 1999, as amended in March 2017, represents, among many, the electricity, transportation, and telecommunication sectors. This study analysed the integrated reporting (IR) governance of selected schedule 2 of PFMA SOEs. The researcher adopted the qualitative approach for the study. Firstly, the analysis was to identify and describe the governance disclosures as evident in IARs using the King IV principles. Secondly, the study analysed the reporting trends associated with governance practices over 2018 – 2020. Integrated reports from Eskom, Transnet, and Telkom were selected for three years. Relevant concepts discussed in the literature review include corporate governance, King reports on corporate governance, King IV principles, the principle of materiality on governance disclosures, corporate reporting, integrated reporting, integrated thinking, benefits of integrated reporting, theoretical underpinnings of the study, and a conclusion. The disclosures were summarised per year and SOE per King IV principle, resulting in nine (9) excel spreadsheets, which were combined excel spreadsheets sorted into a logical structure based on coding to keep track of the source data sequence. The data was systematically manually coded using Ose's (2016) Microsoft Word and Excel method. Findings included seven themes which were ethics, irregular expenditure, internal controls, accountability, governance structures, reputation, and sustainability. Themes were transferred to subtopics for comparative analysis to assess trends and the SOEs’ governance disclosures. The results found that all three SOEs have disclosed using King IV principles guided by the 2013 International Integrated Reporting Council’s (IIRC) framework. All SOEs disclosed their governance in their reports and practice explained. There are noticeable differences, Eskom and Transnet are solely government-owned, and Telkom is partially privatised and run privately as the majority holding is mostly private. Eskom and Transnet reflected more similarities in terms of their operational and financial challenges, whereas Telkom operates in a more competitive environment and is run as a private company which is portrayed to be profitable and restricted to Johannesburg Stock Exchange (JSE) requirements. Disclosures indicate progress on material matters and links associated with functional areas such as strategy and risks. Materiality is a guiding principle in the IIRC framework, which assist discloses information that significantly affects the organisation’s ability to create value over time. The similarities in all three SOEs include challenges in retaining competent and ethical leaders, which is critical for enhancing good governance. The study recommended how the integrated report can be viewed as a management and accounting tool for the governing body and stakeholders to focus on drivers that create value and consider drivers that erode or preserve value. This feedback may assist in informing strategy, business model, and decision-making for the governing body to set governing structures that support the organisation to create sustained value. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2023

Description: Assessed losses provide opportunities to avoid taxation by using various arrangements or transactions. Legislation has been introduced to combat these forms of tax avoidance, in the form of sections 20, 20A, 103(2) and 103(4), and sections 80A to 80L. These sections have also frequently been considered by the courts. The research problem was therefore the analysis of the interaction and effect of the provisions in the Income Tax Act dealing with the use of assessed losses for the purpose of tax avoidance, and the case law interpretation of these provisions. The main goal of the research was to critically analyse the scope and effect of sections 20, 20A, and 103(2) and 102(4), and sections 80A to 80L of the Income Tax Act, dealing with assessed losses, together with the interpretation by the courts. The research was situated within the interpretative paradigm, adopted a qualitative approach, with a doctrinal methodology. As the research was carried out using only publicly available documents, no ethical considerations applied. In addressing the goal of the research, the thesis first discussed the concept of tax avoidance and its consequences. The two main interpretative approaches adopted by the courts, including with regard to tax provisions – the strict literal and the purposive approaches – were described. The thesis then proceeded to analyse sections 20, 20A, 103(2) and 103(4), and sections 80A to 80L, together with the relevant case law, and in the case of sections 80A to 80L, with the use of a hypothetical example, to illustrate the application of the sections. The conclusion arrived at was that the sections discussed in the thesis are adequate to address the problem of the misuse of assessed losses to avoid tax. , Thesis (MCom) -- Faculty of Commerce, Accounting, 2023

Description: This study empirically examined the interconnection among bank competition, regulation and stability of eighteen Zimbabwean banks during the period 2011-2017. Zscore, Capital Adequacy Ratio (CAD), and Loans market share and Deposits market share which are proxies for stability, regulation and competition respectively were examined firstly using the Panel Vector Autoregressive (PVAR) model. Model 1 used loans market share as a proxy for competition and model 2 used deposits market share instead. The stability test using Eigenvalue Stability Condition showed that the PVAR model is unstable. Secondly, the above variables and five bank specific variables (i.e., credit risk, management efficiency, liquidity, return on assets and bank size) were estimated using the Feasible Generalised Least Squares (FGLS) model. The study documents that competition positively contributed to stability and regulation negatively influenced the stability of the Zimbabwean banks. Meanwhile, bank size and credit risk have a negative relationship with stability; management efficiency and liquidity have a positive relationship. Return On Assets has a negative and positive relationship with stability in model 1 and model 2, respectively. The findings implied that to enhance stability, banks must experience a competitive environment, reasonably low minimum capital requirements and cautiously designed regulatory frameworks. , Thesis (MCom) -- Faculty of Commerce, Economics and Economic History, 2023

Description: Neglected tropical diseases continue to pose global concern due to their impact on health and socio-economic status of developing countries in sub-Saharan Africa. African trypanosomiasis is one of the neglected tropical diseases caused by the kinetoplastid flagellate parasite Trypanosoma brucei (T. brucei). The disease is fatal if untreated and the toolbox to combat the disease has been plagued with many difficulties such as drug resistance, toxic chemotherapeutics, and cumbersome drug delivery processes. In recent years, the disease has received attention from organizations such as the Drugs for Neglected Diseases initiative (DNDi) in partnership with WHO as well as academia and industry to provide alternatives to the existing drugs as part of a targeted approach to eliminate human African trypanosomiasis by 2030. The life cycle of the T. brucei parasite requires that it transitions between a cold-blooded vector (the tsetse fly) and a human host. To survive this extreme environmental change and maintain its infectious cycle, the parasite has evolved an arsenal of tools which include a strong immune evasion technique and a robust molecular chaperone system. Heat shock protein 90 (Hsp90) is one of the most abundant eukaryotic molecular chaperones that has been extensively studied in many organisms. It is indispensable for maintaining proteostasis in some organisms and its inhibition is currently being explored as a drug target for cancer and other parasitic diseases. In T. brucei, cytosolic Hsp90 is specifically referred to as Hsp83 due to variations in the sizes amongst different orthologues. Hsp90 is present in high levels in all stages of the T. brucei cell cycle both constitutively and on exposure to stress. To function in the cell, Hsp90 is dependent on co-chaperones, one of which can be found in most organisms, namely, the stress-inducible protein 1 (Sti1). The Hsp90-Sti1 interaction was shown to be crucial for growth in the intracellular kinetoplastid parasite, Leishmania donovani. However, this partnership has not been explored in the extracellular parasite T. brucei. To analyse the interaction of Hsp90 with Sti1 in T. brucei, this study combined in silico, in vitro and in vivo tools. In silico analyses of the Hsp90 complement in T. brucei revealed the presence of twelve putative Hsp90 genes, ten of which code for the cytosolic protein and are arranged in tandem in a head to tail fashion on the same chromosome. One gene each was found for the mitochondrial and ER paralogues of Hsp90, similar to all other species analysed. Eight putative co-chaperones specific to T. brucei were also discovered: six tetratricopeptide repeat domain (TPR) containing co-chaperones and two non-TPR containing co-chaperones. Structural and evolutionary analysis also confirmed that the domains were conserved across the species analysed. T. brucei Sti1 (TbSti1), T. brucei cytosolic Hsp90 (TbHsp83) and human cytosolic Hsp90 (hHsp90) were heterologously overproduced in E. coli and purified using nickel affinity chromatography. With specific antibodies, the expression and localization of the proteins were confirmed. TbSti1 showed strong affinity to the Hsp90s in the nanomolar range, with higher affinity for hHsp90 compared to TbHsp83. TbHsp83 and hHsp90 showed typical chaperone properties by suppressing the aggregation of thermolabile substrate MDH at equimolar concentrations and both chaperones had potent ATP hydrolysis activity. TbSti1, on the other hand, showed no MDH suppression activity and did not affect the ATP hydrolysis activity of TbHsp83 or hHsp90. Ex-vivo experiments using HeLa CRISPR Hop knockout (KO) human cell lines transfected with pcDNA3.1(+)HA-TbSti1 revealed TbSti1 also localized to the cytoplasm. The transfected cells showed a distinct fibroblast-like morphology which was different from the circular morphology seen in the Hop KO untransfected and wild type untransfected cells. Finally, co-immunoprecipitation studies revealed that TbSti1 co-immunoprecipitated with hHsp90. These results show the first characterization of the TbHsp83-TbSti1 partnership in T. brucei. The strong association between both proteins suggests a functional role for this partnership in T. brucei and could provide an updated context for understanding Trypanosome brucei biology. , Thesis (PhD) -- Faculty of Science, Biotechnology and Innovation Centre, 2023
