- Description: When embarking on a journey of preparing a musical work for performance, a contextualisation process is undertaken which informs the performer/s of the factors which govern the parameters of the work. In this study, the author performed Emil Hartmann’s piano trio op. 10 as a part of an integrated master’s degree program. As the composer was not a part of mainland European musical society, information on his life and work was difficult to access, which presented the performer with a contextualisation problem. This study aimed to highlight the process of contextualisation, in the absence of sufficient literary material, through the lens of Emil Hartmann’s piano trio op. 10. The research used a three-pronged methodological approach in order to construct the narrative around Hartmann’s life and composition. Through a structured process of using practice-based research to analyse the creative process undertaken by the practitioners, alongside a micro-historical and analytical methodology, the study builds layers of understanding to inform Hartmann’s narrative, and thus provides interpretational insight into the execution of the work. The research finds that, although it is possible to interpret a musical work based on the musical score, there are layers of depth which cannot be accessed without a contextual understanding of the composer and the conditions in which the composition was written. Through forming the narrative on Emil Hartmann and his piano trio, the research uses the methodology to highlight a method which can be undertaken in the absence of contextual knowledge, and thus presents a contextual understanding of Emil Hartmann’s narrative. With the constructed knowledge, the author uses the findings based on the methodological approaches to weave a narrative around the life of Emil Hartmann. Applying the information discovered in the findings, interpretational approaches are discussed to inform future performances of the work. , Thesis (MMus) -- Faculty of Humanities, Music and Musicology, 2021

- Description: My novella concerns the dynamics of a relationship between two girls. It shows the heterosexual‐like nature of the relationship rather than dwelling on the pressures on lesbians from society as a whole. At its core is the raw emotion and passion of the relationship, which is at the same time toxic, destructive and volatile because of their class differences and other insecurities. The work is influenced by the grit, openness, and innovation of several contemporary writers. , Thesis (MA) -- Faculty of Humanities, Institute for the Study of English in Africa, 2015

- Description: In many service industries, the source of a company’s value has shifted from capital to knowledge and ideas, the quality of which is dependent on its employees (Wooldridge, 2006). In fact, human resources can be considered part of factor conditions which can positively impact on a firm’s competitive context. This impact can ultimately translate into improved financial results (Porter and Kramer, 2002). There is therefore a growing interest in ways to attract and retain talent. According to the managers of many big companies, well communicated corporate responsibility practices can improve staff attraction as well as retention rates by improving morale (CSRwire, 2002). To explore this, a small, creative company in Johannesburg which engages in charity work was selected as a case study, with the goal being to understand whether their culture of good deeds has a positive impact on staff wellbeing. While the owner of the company actively attempts to make the company an enjoyable place to work at, he appears to have initiated the philanthropic activities in a true spirit of giving, rather than with the motive of engaging staff in order to make more money. Nevertheless, the researcher’s investigative stance is that of an enlightened egoist, and the study focuses on the business case of giving being beneficial to the giver (ultimately the company) in the long term, as well as to the recipient. While the danger of suggesting that philanthropy could be instrumentalised is acknowledged (Morton, 2004), the investigation explores the possibility because such evidence could persuade other companies to become more socially concerned. Through a qualitative approach involving interviews, observation and analysis of video footage, it becomes apparent that there is clearly value for the staff in the charity work they do. Unfortunately the multiple initiatives undertaken to keep staff morale high at the company make it impossible to establish a clear link between the philanthropy and overall wellbeing, but as the study was conducted in the phenomenological paradigm the main concern was with understanding the experience of participants. However, an unexpected finding was that the employees derive great satisfaction from using their professional skills for charity work rather than just donating money to the charity. They feel that their skills uniquely position them to make significant changes to the lives of others, which gives them a sense of pride and achievement that they don’t necessarily experience in their ordinary activities at work. On the basis of this, it is recommended that companies look to involve staff with projects that require their specific expertise when evaluating philanthropic initiatives. , Thesis (MBA) -- Faculty of Commerce, Rhodes Investec Business School, 2008

- Description: The use of renewable energy is increasing every year as it is seen as a viable and sustain- able long-term alternative to fossil-based sources of power. Emerging technologies are being merged with existing renewable energy systems to address some of the challenges associated with renewable energy, such as reliability and limited storage facilities for the generated energy. The Internet of Things (IoT) has made it possible for consumers to make money by selling off excess energy back to the utility company through smart grids that allow bi-directional communication between the consumer and the utility company. The major drawback of this is that the utility company still plays a central role in this setup as they are the only buyer of this excess energy generated from renewable energy sources. This research intends to use blockchain technology by leveraging its decentralized architecture to enable other individuals to be able to purchase this excess energy. Blockchain technology is first explained in detail, and its main features, such as consensus mechanisms, are examined. This evaluation of blockchain technology gives rise to some design questions that are taken into consideration to create a low-energy, low-computation Ethereum-based blockchain network that is the foundation for a peer-to-peer energy trading system. The peer-to-peer energy trading system makes use of smart meters to collect data about energy usage and gives users a web-based interface where they can transact with each other. A smart contract is also designed to facilitate payments for transactions. Lastly, the system is tested by carrying out transactions and transferring energy from one node in the system to another. , Thesis (MSc) -- Faculty of Science, Computer Science, 2021

- Description: Base erosion and profit shifting is defined as the use of tax planning strategies by multinational enterprises, often through exploiting gaps and mismatches between the countries in which they operate (OECD, 2021: p. 1). Multinational enterprises exploit these gaps through the use of transfer pricing. Goods and services are exchanged between connected persons or associated enterprises at prices that do not reflect their arm’s length price, in order to shift profits from high tax to low tax jurisdictions. In terms of section 31 of the Income Tax Act, transactions between connected persons or associated enterprises must be reflected at their arm’s length price. Transfer pricing has become an issue due to the difficulties in determining an appropriate arm’s length price. Disputes arise between a taxpayer and a tax administration on the methods to use to determine an appropriate transfer price. The use of Advance Pricing Agreements prevents these disputes from arising and provides tax certainty on the treatment of transactions for both the taxpayer and the tax administration. While the OECD recommends the use of Advance Pricing Agreements as a method to prevent disputes from arising, the OECD also argued that if a country has the resources to conduct an audit, an Advance Pricing Agreement will not lead to increased revenue collection. The research therefore analyses the problems faced in determining an appropriate arm's length price and compares the role that Advance Pricing Agreements and audits play in addressing transfer pricing issues. The possible role of Advance Tax Rulings is also explored, but they are found not to be suitable, except for the most simple transactions. The research applies a legal interpretative, doctrinal research methodology and a qualitative research method. The data comprised of relevant South African tax legislation, OECD Guidelines, the World Bank Handbook, and the UN Manual, together with the writings of acknowledged experts in the field. The study establishes that a proper functioning audit system is crucial to increasing revenue collection once a country implements an Advance Pricing Agreement. The research therefore recommends the adoption of Advance Pricing Agreements in South Africa as a dispute prevention measure. , Thesis (MCom) -- Faculty of Commerce, Accounting, 2023

- Description: The Namibian Science curriculum clearly states that learning of science should be promoted through using inquiry-based approaches. However, it does not state how teachers should go about promoting inquiry-based approaches in their classrooms, especially in under-resourced rural schools. This is exacerbated in part by the fact that there is inadequate or lack of professional development for science teachers which focus in particular on promotion of inquiry-based approaches. As a result, science teachers tend to ignore inquiry-based approaches in their classrooms. It is against this background that my study sought to explore how the use of a ‘mini-ecosystem’ enables and/or constrains grade 5 learners from an under-resourced rural school to make sense of scientific inquiry. The study is underpinned by an interpretive paradigm. Within the interpretive paradigm, a qualitative case study approach, using the Predict-Explain-Explore-Observe-Explain (PEEOE) framework was adopted. This case study was carried out in an under-resourced rural Namibian school and the participants were grade 5 Natural Science and Health Education learners. I also invited a teacher from the school to be my critical friend and a participant observer. Data were generated using the Views About Scientific Inquiry (VASI) questionnaire, observations, focus group interviews and learners’ reflections. Vygotsky’s socio-cultural theory was my theoretical framework, and within this theory, I used mediation of learning, social interactions, the zone of proximal development and self-regulation as lenses to analyse my data. A thematic approach to data analysis was adopted. That is, qualitative data were analysed inductively to come up with sub-themes and thereafter common sub-themes were combined to form themes. The findings of the study revealed that the observation of mini-ecosystems enabled learners to interact and participate with each other in their respective groups. Moreover, learners were able to identify some scientific concepts such as evaporation, condensation, water cycle and rainfall. These findings are in contrast with the fact that they seemed to struggle to answer the VASI questionnaire that was conducted prior to observation. The study thus recommends that science teachers should make efforts to use easily accessible resources such as a ‘mini-ecosystem’ to promote scientific inquiry amongst their learners. , Thesis (MEd) -- Faculty of Education, Education, 2022

- Description: The following paper aims to analyse lines 660 – 774 of Euripides’ Bacchae paying close attention to the representation of the bacchants in the account given to Pentheus by the herdsman.1 Accompanying the translation is a brief commentary further elaborated and discussed in the paper below. The purpose of this paper is to investigate how the Theban women are portrayed in the hills outside of Thebes and the implications this might for the inherent conception of the supposed structure of the polis and the oikos. Dionysos’ arrival in Thebes hails a systematic disruption of the social order of the Theban polis. His presence causes an inverting of all that is familiar to the Thebans, the unknown becomes known and the known reveals itself as unknown. Euripides’ Bacchae was first performed at the City Dionysia in 405 BCE, in the year after the tragedian’s death. The play dramatises the arrival of the god Dionysos to Thebes to exact vengeance on those responsible for his mother’s death and to establish his mysteries there (line 24f & 47f). Before one can begin any analysis of the text, it is important to establish the context established by the play, as this context is important to a fuller understanding of the text. , Thesis (MA) -- Faculty of Humanities, School of Languages and Literatures, 2021

- Description: This study observes the literacy engagement of a group of learners enrolled in Grades 8–10 in Nombulelo High School, a poorly-resourced school in the city of Makhanda in the Eastern Cape, South Africa. The learners participated in a book club hosted and run by St Andrew’s College, a privileged independent school, as a community engagement initiative. The idea of extending literacy engagement and engagement with written texts beyond textbooks used in schools is critical for learners with ambitions to enter higher education. Studying at a university requires a lot of reading, and if reading has not been taken up as a practice that involves more than ‘text consulting’ (Geisler, 1994) students will be unlikely to read the number of texts required of them. Studies (see Geisler, 1994 for an overview) have shown how the literacy of the university is very different to school based literacies. The assumption behind the study on which this thesis reports is that engagement with fictional texts might promote reading and bring about understandings of this activity as enjoyable and not a task only associated with schooling. The study is underpinned by a critical realist philosophy which allowed for the identification of structures and mechanisms that led to the emergence of literacy events in learners’ lives and to their experiences and observations of those events. The study was guided by the following questions: How do learners from a poorly-resourced high school engage around fictional texts in the context of a book club? What enables or constrains this engagement? The study was impacted by the Covid-19 pandemic in that lockdown requirements meant that learners from St Andrew’s College could not participate in the book club as much as anticipated initially as they had been forced to return home to pursue online learning. Learners from Nombuelo High School were, however, granted access to College premises, where they met in the school library following strict Covid protocols. The study draws on in-depth interviews, observations and document analysis of five learners from Nombulelo High School who participated in the book club, as well as on book reviews they wrote for the book club website. The critical realist analysis allows for the identification of mechanisms in learners’ homes and communities that enable literacies, including those that are screen-based such as using a computer, mobile phones and other technologies. This study found evidence of challenges regarding school based texts, reading fictional texts and viewing it as an enrichment of the school project. Because of children were African the emergence of communal practices and story telling is woven throughout the results section. However, is an example of the complexity of social and economic challenges facing South African marginalised schools. , Thesis (MEd) -- Faculty of Education, Centre for Higher Education Research, 2022

- Description: This study observes the literacy engagement of a group of learners enrolled in Grades 8–10 in Nombulelo High School, a poorly-resourced school in the city of Makhanda in the Eastern Cape, South Africa. The learners participated in a book club hosted and run by St Andrew’s College, a privileged independent school, as a community engagement initiative. The idea of extending literacy engagement and engagement with written texts beyond textbooks used in schools is critical for learners with ambitions to enter higher education. Studying at a university requires a lot of reading, and if reading has not been taken up as a practice that involves more than ‘text consulting’ (Geisler, 1994) students will be unlikely to read the number of texts required of them. Studies (see Geisler, 1994 for an overview) have shown how the literacy of the university is very different to school based literacies. The assumption behind the study on which this thesis reports is that engagement with fictional texts might promote reading and bring about understandings of this activity as enjoyable and not a task only associated with schooling. The study is underpinned by a critical realist philosophy which allowed for the identification of structures and mechanisms that led to the emergence of literacy events in learners’ lives and to their experiences and observations of those events. The study was guided by the following questions: How do learners from a poorly-resourced high school engage around fictional texts in the context of a book club? What enables or constrains this engagement? The study was impacted by the Covid-19 pandemic in that lockdown requirements meant that learners from St Andrew’s College could not participate in the book club as much as anticipated initially as they had been forced to return home to pursue online learning. Learners from Nombuelo High School were, however, granted access to College premises, where they met in the school library following strict Covid protocols. The study draws on in-depth interviews, observations and document analysis of five learners from Nombulelo High School who participated in the book club, as well as on book reviews they wrote for the book club website. The critical realist analysis allows for the identification of mechanisms in learners’ homes and communities that enable literacies, including those that are screen-based such as using a computer, mobile phones and other technologies. This study found evidence of challenges regarding school based texts, reading fictional texts and viewing it as an enrichment of the school project. Because of children were African the emergence of communal practices and story telling is woven throughout the results section. However, is an example of the complexity of social and economic challenges facing South African marginalised schools. , Thesis (MEd) -- Faculty of Education, Centre for Higher Education Research, 2022

- Description: At its most effective my research hopes to re-affirm the central value and importance of self-inquiry. That is, I hope to echo the familiar call of the wise to know thyself. Of the many mouths and temple walls that have lent authority to this precept there is perhaps no mouth more important than one’s own. To know thyself is the task and responsibility of the individual. In order to arrive at the point where I can re-affirm its value I explore the nature of self-inquiry with the help of Plato, Patanjali and a comparison between them. I propose two general senses in which we might understand self-inquiry and seek to bring out the core problems faced by each. We find an account of these two senses and the relationship between them in both Plato and Patanjali, so too, though less obviously, in the comparison between them. The comparison provides the opportunity for reflecting on the ground that it moves from and depends on, the common ground we assume between the two compared philosophers/ies. I contend that this ground is ultimately the comparer, one’s self. The consequence is that the comparative project and the project of self-inquiry both meet and are mutually beneficial. The three together; Plato, Patanjali, and the comparison between them help us account for nature of self-inquiry in helping us to better understand the relationship between the two senses in which we can come to understand and think about it. In the first sense, self-inquiry is cast as the examination of one’s life. In the second sense, we are invited to consider the possibility of an unmediated knowing of the examiner, an unmediated self-knowing. With a better understanding of what self-inquiry is I stand to conclude by re-affirming its value. , Thesis (MPhil) -- Faculty of Humanities, Philosophy, 2021

- 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: The harvest of Loligo reynaudii, or "chokka," represents a critical source of revenue and job creation in the historically impoverished Eastern Cape Province of South Africa. Due to the importance of visual stimuli in the reproductive processes, it has been hypothesized that a primary driver of successful reproduction is the clarity of the water column. The presence of increased particulate matter concentrations within the water column generates turbid conditions near the seafloor (visibility < 1m), that are proposed to restrict spawning activity. This benthic nepheloid layer (BNL) contains both organic and inorganic components, with the BNL intensity a function of bottom turbulence, substratum type, and detritus level. However, the spatial and temporal resolution of BNL intensity on the Eastern Agulhas Bank (EAB) and the environmental drivers thereof remain unknown. Here we show that benthic turbidity events are a common but highly variable occurrence on the EAB. Results from a 17-month time-series of in-situ and remote sensing data between 2002 – 2004 in Algoa Bay, supplemented by experiments in other bays important for spawning, show that turbid conditions existed for ∼ 30 % of the sample period. Exploration of environmental drivers, including the influence of wind, altimeter-derived significant wave height (Hs), sea surface temperature (SST), and chlorophyll-a (Chl-a) concentrations indicate that BNL intensity does not conform to a "one-size-fits-all" approach. Rather, complex local hydrological and physiochemical parameters control the BNL characteristics on the EAB. Global warming is likely to increase the frequency and intensity of extreme westerly-wind and storm events, promoting BNL events on the Eastern Agulhas Bank and possibly causing a shift in the reproductive strategy of chokka squid to the cooler mid shelf region. This is likely to have consequences for both the species in terms of reproductive success and the fishery, which is concentrated on inshore spawning aggregations. Future research needs to quantify and characterize the constituents, source particles and spatial-temporal variability of BNL events in order to build a predictive capacity. Through incorporating the qualitative analysis of the dynamics of nepheloid layers on the EAB into Regional Oceanographic Models (ROMS), General Linear Models (GLM) and particle distribution models such as DELFT-3D, it is possible to move toward predicting the timing and intensity of these events. , Thesis (MSc) -- Faculty of Science, Ichthyology and Fisheries Science, 2022

- Description: Pereskia aculeata Miller (Cactaceae) is a primitive creeping cactus that originated from South America and has become an invasive alien plant in South Africa and Australia. Due to its vine-like growth form mechanical and chemical control are not feasible options for its control, therefore biological control is the best option for controlling this plant. Phenrica guerini (Bechyné) (Chrysomelidae) is a leaf-feeding flea beetle that has been released as a biological control agent against Pe. aculeata in South Africa and has been shown to be damaging at some sites in the country. In this thesis, further studies into the use of Ph. guerini as a biological control agent against Pe. aculeata were conducted to determine whether the beetle should be released as an agent against the target weed in Australia. The host range of a potential biological control agent is important to determine as only monophagous agents, or agents with suitably restricted host ranges, should be considered for release. Host specificity testing was conducted to determine if Ph. guerini was suitably specific for release in Australia. Phenrica guerini larvae only fed and partially developed on three out of 25 test plants, but failed to pupate on any plants besides Pe. aculeata. Adult beetles did not feed on any test plants and only oviposited on one test plant species. Phenrica guerini did not develop on any plant other than the target weed and is therefore suitably host specific for release in Australia. The efficacy of a potential agent is also important to consider as the release of an ineffective agent can reduce the success of a biological control programme. A laboratory based pre-release efficacy assessment was done to determine the impact that Ph. guerini could have on Pe. aculeata. There was a significant difference between the control plants and those with larvae, with an average of 72 (S.E. ± 12.33) less leaves on plants with feeding and the main stem of the plant being 11.1 cm (S.E. ± 7.17) shorter. Although there were no significant differences observed in the number of additional stems, and weights of the different plant parts, this was not a long term study and many of these differences would not have been observed in a short period. Based on the impact observed on the leaves and the main stem, and various field studies that have been done to assess the impact of Ph. guerini on Pe. aculeata in the field in South Africa, Ph. guerini appears to be a potentially damaging agent. As Pe. aculeata is still in its early stages of invasion in Australia the beetle has the potential to be damaging and reduce the invasion trajectory of the plant. This study showed that the beetle is suitably host specific and potentially damaging enough to be recommended for release as a biological control agent against Pe. aculeata in Australia. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2022

- Description: This study examines a history of urban research on ancestral belief of amaXhosa within the Greater East London region, Eastern Cape, South Africa which spanned much of the 20th century (1934–2002). Through extensive textual and literary investigation, this thesis offers new perspectives on this topic. Current theoretical explorations offer the tools to reassess the positionality of the researchers and in light of findings of these previous studies, highlighting above all, the presence of certain academic ‘blind-spots’. These ‘blind-spots’ are argued to have been caused by theoretical and methodological constraints, particularly around Western-centric definitions of the nature of 'modernity' that rely on the positivist notion of a singular unilinear path of time as a universal standard (and which thus defines 'progressiveness' and 'backwardness'). (These ‘blind spots’ were notably further strengthened by a Eurocentric interpretation of identity and a trend of Neo-Marxist scholarship between the 1970s and the 2010s1 which created a ‘taboo’ on addressing issues of culture, and especially of ancestral spirituality, as this was taken to be portraying Africans as culturally ‘static’ and backward and therefore supporting Apartheid ideologies of ‘separate development’). Through these textual investigations this thesis brings to light the, largely unrecognised, core of the issue or driving factor behind the difficulties in all of these previous studies. This is posited as the existence of a prevailing culture of ‘silence’ in Xhosa spaces (stretching from 1840–2000) regarding the sustained importance of 'Redness' (ancestral spirituality and traditional dimensions of identity due to the notion that it was 'backward'). This self-censoring is unpacked as having been an expedient response by many to the requirements for Xhosa pagans to wash off the symbolic red cosmetic clay at baptism, put on ‘decent’ Western clothing and shoes and take on Christian first names (‘shedding’ their previous names and identities) as processes deemed necessary to properly convert to Christianity (Frescura, 2015). More significantly however, it has been argued by scholars that adopting Christianity was the only way to be able to harness the power of education at a time of starvation related to the famine of the millennial Cattle Killing movement (1856–7) and the Xhosa military defeat at the end of the 100-year period of the British Xhosa Frontier Wars (1779–1879). This thesis uses perspectives offered by Queer theory to unpack the pain of this 'veiling' of aspects of identity as a necessary strategy for achieving economic 'success' amid the structural and epistemological violence of colonialism and apartheid. It is suggested that a combination of the ‘silence’ and ‘taboo’ area of the ‘blind-spot’ could completely ‘veil’ these epistemological realities from the view of many earlier researchers of urban Xhosa identity (whose cultural and linguistic backgrounds as well as etic positioning caused them to be unable to 'knock' to gain access into this normally ‘veiled’ world). This thesis combines these historical perspectives with contemporary scholarship and literary works to propose that these ‘Red’ aspects of identity and spirituality have always and still ‘continue’ to form a core, or crux, of Xhosa identity for a previously widely unrecognised and overwhelming majority of urban amaXhosa. This thesis uses the perspective offered by a Xhosa translation of the title of Mda's English language novel, 'A Heart of Redness’ (2000), to explore the importance of ancestral spirituality and clan identities to amaXhosa as a [previously invisible/veiled] ‘Redness of one's Heart’ for a high proportion of contemporary amaXhosa. In this way, this thesis agrees with scholars such as Latour (1993) and Mignolo (2007) in their 'jarring' expose regarding the epistemic violence of euro-normative notions of ‘modernity’. Here they call for a disruption of the pervasive idea of the West as being at the 'forefront' of human experience and even a challenge to the western reading of time. Finally, through exploring critique of the 'Secularisation Thesis' of the Western world, this thesis poses the implicit question contained in its title: ‘Is the western world now perhaps able to embrace a 'modernity' and integrative-cosmology that has been safe-guarded by Xhosa pagans since the 1840s?’ This study documented numerical indicators on the presence of ancestral belief and traditional dimensions of Xhosa identity from fieldwork conducted in an urban locality King William’s Town (Qonce) within the Buffalo City Municipality, Eastern Cape of South Africa from September 2018 to December 2019. In-depth quantitative and qualitative data were collected from lengthy interactions with 305 consenting Xhosa participants. These interactions comprised 129 semi-structured and 176 structured interviews, 61 of the latter formed the sample for numerical data analysis with which to give clarity on the abiding importance of ancestral spirituality for a vast majority of urban amaXhosa. , Thesis (MA) -- Faculty of Humanities, Anthropology, 2023

It is suggested that a combination of the ‘silence’ and ‘taboo’ area of the ‘blind-spot’ could completely ‘veil’ these epistemological realities from the view of many earlier researchers of urban Xhosa identity (whose cultural and linguistic backgrounds as well as etic positioning caused them to be unable to 'knock' to gain access into this normally ‘veiled’ world). This thesis combines these historical perspectives with contemporary scholarship and literary works to propose that these ‘Red’ aspects of identity and spirituality have always and still ‘continue’ to form a core, or crux, of Xhosa identity for a previously widely unrecognised and overwhelming majority of urban amaXhosa. This thesis uses the perspective offered by a Xhosa translation of the title of Mda's English language novel, 'A Heart of Redness’ (2000), to explore the importance of ancestral spirituality and clan identities to amaXhosa as a [previously invisible/veiled] ‘Redness of one's Heart’ for a high proportion of contemporary amaXhosa. In this way, this thesis agrees with scholars such as Latour (1993) and Mignolo (2007) in their 'jarring' expose regarding the epistemic violence of euro-normative notions of ‘modernity’. Here they call for a disruption of the pervasive idea of the West as being at the 'forefront' of human experience and even a challenge to the western reading of time. Finally, through exploring critique of the 'Secularisation Thesis' of the Western world, this thesis poses the implicit question contained in its title: ‘Is the western world now perhaps able to embrace a 'modernity' and integrative-cosmology that has been safe-guarded by Xhosa pagans since the 1840s?’ This study documented numerical indicators on the presence of ancestral belief and traditional dimensions of Xhosa identity from fieldwork conducted in an urban locality King William’s Town (Qonce) within the Buffalo City Municipality, Eastern Cape of South Africa from September 2018 to December 2019. In-depth quantitative and qualitative data were collected from lengthy interactions with 305 consenting Xhosa participants. These interactions comprised 129 semi-structured and 176 structured interviews, 61 of the latter formed the sample for numerical data analysis with which to give clarity on the abiding importance of ancestral spirituality for a vast majority of urban amaXhosa. , Thesis (MA) -- Faculty of Humanities, Anthropology, 2023

- Description: The case study method was used to investigate the manifestations of the death instinct as evidenced in a pathological organization. Work of Kleinian analysts in this area was employed as a basis for interrogating the material that emerged in a five month psychotherapy with a borderline disordered patient. It was demonstrated how the pathological organization was employed as a means of evading paranoid- schizoid fears and depressive position anxieties. Two ways in which defences were assembled into the pathological organization could be traced, both leading to resistance in the therapy. The one set of defences would entail a complete withdrawal from contact, where the patient would hold herself aloof from experience through a solitary invulnerability. The other set of defences involved an active attack on the vulnerable, libidinal self. Identified with the bad, anti-libidinal self, the patient would attempt to annihilate the libidinal self in various ways. Fragmentation of her thoughts and memories, self-destructive behaviour and phantasized and actual attacks on the objects in her world which called forth her neediness were all evidenced. In conclusion, the issue of whether a more active interpretation of the manifestations of the death instinct or a less interpretative, more holding therapeutic stance should be adopted in the therapy with patients exhibiting a pathological organization was raised. , Thesis (MA) -- Faculty of Humanities, Psychology, 1991

- Description: The journey of substance use recovery is an inherently dynamic and on-going process. It is advanced through secure social support systems. Furthermore, requiring the explicit practice of self-advancement and self-efficacy. However, in South Africa, despite the continued upsurge of substance abuse, there remains a substantial gap between the high demand for treatment and the limited capacity to provide state-funded treatment. In addition, various psychosocial and socio-economic factors further impede access to treatment or recovery support. Thus, within communities facing SUD treatment barriers the exploration of individual lived experiences may deepen understandings of how men experience the journey of substance use recovery. , Thesis (MA) -- Faculty of Humanities, Psychology, 2023

- Description: “Drive for show, putt for dough”. This controversial adage has been a prominent sentiment in the game of golf for decades. Empirical evidence investigating its robustness through determinant of earnings inquiries have identified that the most valuable measure of performance in golf is in fact putting. However, with the ever-perpetuating state of golf equipment and the technologies thereof, the distance debate in golf has thus gained traction. Recent investigations and evidence into the adage had identified a trend-shift with regards to the value associated with distance achievable and putting ability in golf. Therefore questioning the relevance of the adage in the modern form of the game. In conducting a determinant of earnings inquiry through the engagement of engineering “pure” performance measures as empirically identified, this investigation is aimed at recognising a similar trend in a South African perspective, on the Sunshine Tour. Utilising a generalised least square regression methodology, the analysis identifies how the value of the marginal product as-sociated with both player and non-player explanatory measures influence real earnings on the Sun-shine Tour. This determination is observed through the means of a comprehensive scenario analysis, demonstrating the effect of marginal performance differences to the degree of 1% and 5% increase in performance. A trend was therefore identified in which the value of the marginal product, and growth in real earnings associated to driving distance at the 5% level were in fact greater than the that of putting ability. The results further denote the robustness of the adage and the inherent value associated to putting vs. driving distance at the 1% level. The conclusion to this investigation demonstrates the importance of opportunistic positions player’s put themselves in within tournaments to encourage earnings accumulation. Identified through balanced return on investments for all performance measures to “drive for dough to putt for dough”. , Thesis (MEcon) -- Faculty of Commerce, Economics and Economics History, 2023

- Description: The regulation of professionals who offer any type of service to the public is a critical intervention towards protecting the public from unscrupulous behaviour. The regulation of tax practitioners is no exception as it is a critical element in protecting the taxpaying public and the fiscus against improper conduct by tax practitioners, as well as preventing revenue leakages due to inaccurate or incorrect declarations made by taxpayers. A major contributor of regulation would be strengthening or improving compliance. This study analyses the frameworks that regulate tax practitioners in Zimbabwe and South Africa and evaluates them against best practice as is found in Germany. Germany has been regulating tax practitioners for 50 years and can rightly be recognised as best practice. This is achieved by reviewing and evaluating institutional and legislative mechanisms in the regulatory frameworks adopted in the three countries in order to identify possible areas of improvement in Zimbabwe and South Africa. The research is situated in the interpretative paradigm and the research methodology is qualitative in nature, involving the critical review of documentary data. The study concludes that both South Africa and Zimbabwe have room to improve in certain areas and makes recommendations aimed at strengthening their respective regulatory frameworks. Both South Africa and Zimbabwe could promulgate a law that deals exclusively with the regulation of tax practitioners, and institute an independent body that deals exclusively with tax practitioner related issues. In Zimbabwe, the Public Accountants and Auditors’ Board should be replaced with a body dedicated to serving tax practitioners. Informing the taxpaying public is important and, particularly in Zimbabwe, measures should be adopted to inform taxpayers about their rights and obligations, the role of tax practitioners, and the interface with the tax administration. The Zimbabwean regulatory model should also recognise other non-accounting and auditing-oriented professions, such as the law profession, as tax practitioners. , Thesis (MCom) -- Faculty of Commerce, Accounting, 2023

- Description: A better appreciation of the physical geography and environmental factors that play a role in the movement of the Chacma baboon troop in and around Pringle Bay (Overberg Municipality) and part of the Kogelberg Biosphere could lead to a better understanding of their movement. In turn, this insight may contribute to reducing the human‐wildlife conflict that has arisen in the town. Humanwildlife conflict escalated after the rapid urban development that followed the introduction of electricity in 1993. The baboon‐human conflict in Pringle Bay is, in part, due to habitat loss caused by urban development and the easy availability of food in the urban area. The wild animal’s natural behaviour (seeking food and fresh water) and the human way of living (food and waste management) has led to baboon habituation and increased raiding in the village. The objective of this geographic study was to understand the baboon troops spatial and temporal movements. Two methods are being used to track the baboon troop. The first method entails collection of data from GPS tracking collars which record the location of the baboons at 30 minute intervals. This is considered a reliable, but invasive and expensive method where the alpha male and female baboon had to be captured and fitted with tracking collars. The second method entails using volunteered geographic data, in this case, information from a WhatsApp baboon alert group. While this provided data at no real cost, the mining of the information was challenging and building a geodatabase was time consuming. However, this citizen science approach added valuable data and was able to identify human‐wildlife conflict sites in the urban area. The baboon location data was mapped using GIS. Primary and secondary spatial data was sourced and added to the geodatabase created in ArcMap 10.7. Various ArcMap tools were used in analysing the environmental factors (climate, vegetation, water sources and topography) together with the location data. Analysis of this data allowed the range of the baboons to be mapped, showing the maximum extent of the territory the baboons move in. The was refined by mapping their home range (defined as the area in which they spend 95% of the time) and their core area (in which they spend 50% of the time). High activity areas ‐ or hotspots ‐ were identified, as were the baboon sleep sites. The data allowed for habitat use and seasonal patterns of movement to be explored. A key finding of the research was that the baboons were observed outside of the urban area for 82% of the time. The baboons spent the majority of their time in mountain fynbos vegetation. Hotspot areas showing significant baboon activity were identified within the town and close correlation with their sleep sites and wetland areas was evident. No definitive seasonal or weather patterns were found that influence the baboon distribution. Baboon management is complex and difficult. The sustainability of the baboon troop is important for the biodiversity of the Kogelberg Biosphere Reserve. While the baboons should not be encouraged to enter the urban area, the residents should play a role in reducing the availability of food and baboonproofing their properties. The Overstrand Municipality also needs to address waste management and waste collection in the town. Understanding the biogeography of the baboons and implementing the above‐mentioned mitigating management measures would encourage human‐wildlife coexistence and inform future baboon management plans. , Thesis (MSc) -- Faculty of Science, Geography, 2021

- Description: The Helicoverpa armigera stunt virus (HaSV), belonging to the Family Alphatetraviridae (Genus: Omegatetravirus), is a non-enveloped insect virus encapsidating a bi-partite, positive-sense single-stranded RNA genome. RNA1 encodes the replicase, as well as three small open reading frames (ORFs) arranged in tandem, and overlapping with the 3’ end of the replicase ORF. These ORFs, designated p11, p15 and p8, encode putative proteins of unknown function. The p11 and p15 ORFs are conserved in the genome of the related Omegatetravirus, Dendrolimus punctatus tetravirus. In HaSV, the stop codon of p11 is followed immediately by the start of p15, whereas the stop of p15 and start of p8 are separated by a glycine intercodon. Furthermore, only p11 is known to have a recognizable Kozak sequence. The aim of this study was to determine the expression and function of these three small proteins in the HaSV infectious lifecycle. The authenticity of the viral cDNA sequence, encoding the three small ORFs, was validated by sequencing multiple cDNA clones of the relevant region in viral RNA (vRNA), purified from infectious HaSV particles. The sequence of all three ORFs was conserved in seven cDNA clones, while point mutations were observed in each of two remaining cDNA clones, suggesting that the ORFs were conserved in infectious virus. Polyclonal antisera were raised against a p11 peptide, and a recombinant p15-p8 fusion protein (p23) expressed and purified from Escherichia coli. The affinity of the anti-p23 antiserum was confirmed by western blot analysis, while that of the anti-p11 antiserum was confirmed using immunofluorescence microscopy, as attempted expression of recombinant p11 in E. coli appeared to be toxic. The antisera were used to detect expression of the small proteins in HaSV-infected H. armigera larvae by western blot analysis. A band migrating at approximately 34 kDa was detected by both antisera in infected larvae, absent in uninfected larvae, suggesting the expression of a p11-p15-p8 polyprotein. Protein bands of 11 kDa and 8 kDa were also detected by the anti-p11 and anti-p23 antisera, respectively. Bioinformatic analysis revealed that the polyprotein would be produced by a novel type of stop codon read-through, however the mechanism required for individual expression could not be definitively determined. The mechanism by which these ORFs are translated was further investigated by expressing p11-p15, tagged with FLAG and enhanced green flourescent protein (EGFP) at its amino- and carboxyl-termini respectively (FLAG-p11-p15-EGFP), in Spodoptera frugiperda (Sf9) cells detected by flourescence microscopy. Punctate structures were observed throughout the cytoplasm that were also detected with antiFLAG, anti-p11 and anti-p23 antisera, complementing results obtained in previous studies. Since p15 does not exhibit a strong recognizable Kozak like p11, the dependency of p15 expression on that of p11 was investigated by mutating this construct such that p15 occurred in a +1 frame to p11. Both EGFP and anti-p23 fluorescence was detected with the same cytoplasmic distribution as the unmutated construct, whereas nothing was detected by anti-FLAG and anti-p11. Preliminary results therefore suggested p15 may also be expressed as a discrete protein, independent of p11. , Thesis (MSc) -- Faculty of Science, Biochemistry and Microbiology, 2018

- Description: The research conducted for the dissertation entitled “An exploratory study of King IVTM: The effect of principle four and its practices in achieving good performance by selected JSE-listed companies”, aimed to determine whether principle four, namely the creation of value, and the application by an organisation of the recommended practices as set out in King IVTM, contribute to the achievement of good performance. The research outlined the background to the research by describing the history of the development of corporate governance internationally and in South Africa, dating back to 1932 and culminating with the King IV™ report. It described the problem statement, defined the aims and objectives of the study, and demonstrated that the significance of the study lies in its exploration of the relationship between the King IV™ practices and good performance. The research also provided a review of the related literature, describing the theoretical background for the research, which includes the conceptual framework and propositions of the research. The research was situated in the post-positivist paradigm, the methodology was qualitative, and the method adopted was a theory-based evaluation, based on a deductive thematic analysis with pattern matching. From a detailed reading of the integrated reports and the King IVTM compliance registers of the fifteen selected listed companies for the years 2017 to 2019, hits and misses in relation to the six capitals and the eight associated practices were recorded. From this, the resulting descriptive statistics were calculated and set out in the form of tables, and a regression analysis was used to support the findings. The research revealed, based on the descriptive statistics data that there is a moderate relationship between good performance and the application of the eight practices set out in King IVTM, that contribute to the achievement of good performance. It was, therefore, concluded that the adoption of corporate governance principles and practices has an effect on performance, although it may not be significant. It is also concluded that the application of the practices in terms of principle four as set out in King IVTM is achieving its intended outcome - the creation of value. The research also concluded that good performance constitutes more than just a company performing financially and that all companies need to comply with the requirements of King IVTM, as the Code is designed to guide organisations in achieving good corporate governance. Governance principles and practices should be adopted in a way that does not unduly constrain them and is appropriate to a company’s particular circumstances. Complying with corporate governance principles and implementing the recommended practices might not guarantee positive outcomes (good performance), but it will guide the board of directors in the pursuit of ethical and effective leadership, and that of sustainable development in order to meet the needs of all stakeholders. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2022

- Description: The research conducted for the dissertation entitled “An exploratory study of King IVTM: The effect of principle four and its practices in achieving good performance by selected JSE-listed companies”, aimed to determine whether principle four, namely the creation of value, and the application by an organisation of the recommended practices as set out in King IVTM, contribute to the achievement of good performance. The research outlined the background to the research by describing the history of the development of corporate governance internationally and in South Africa, dating back to 1932 and culminating with the King IV™ report. It described the problem statement, defined the aims and objectives of the study, and demonstrated that the significance of the study lies in its exploration of the relationship between the King IV™ practices and good performance. The research also provided a review of the related literature, describing the theoretical background for the research, which includes the conceptual framework and propositions of the research. The research was situated in the post-positivist paradigm, the methodology was qualitative, and the method adopted was a theory-based evaluation, based on a deductive thematic analysis with pattern matching. From a detailed reading of the integrated reports and the King IVTM compliance registers of the fifteen selected listed companies for the years 2017 to 2019, hits and misses in relation to the six capitals and the eight associated practices were recorded.
