- Description: A series of mostly asymmetrical spiro orthocarbonates and heterospirocyclic derivatives of orthocarbonic acid was synthesized from 2,2-dichlorobenzodioxole and a number of difunctional reagents. A systematic study of the size of the chelate rings formed around the spirocentric carbon atom was conducted by selecting representative samples of aliphatic and aromatic diols. The feasibility and scope of potential starting materials used was expanded by reacting DCBD successfully with thiols. Molecular structures of these compounds were confirmed using diffraction studies on single crystals. All compounds were analyzed using multinuclear NMR. DFT calculations performed on the compounds allowed for the development of equations that can accurately predict 13C chemical shifts of SOCs. Furthermore, the experimental NMR spectroscopy gave rise to an increment shift system for the 13C NMR shifts allowing for further assignment of carbon atom positions in compounds with multiple possible bonding patterns. , Thesis (MSc) -- Faculty of Science, School of Biomolecular & Chemical Sciences, 2024

- Description: The 21 cm transition from neutral Hydrogen promises to be the best observational probe of the Epoch of Reionisation (EoR). It has driven the construction of the new generation of lowfrequency radio interferometric arrays, including the Hydrogen Epoch of Reionization Array (HERA). The main difficulty in measuring the 21 cm signal is the presence of bright foregrounds that require very accurate interferometric calibration. However, the non-smooth instrumental response of the antenna as a result of mutual coupling complicates the calibration process by introducing non-smooth calibration errors. Additionally, incomplete sky models are typically used in calibration due to the limited depth and resolution of current source catalogues. Combined with the instrumental response, the use of incomplete sky models during calibration can result in non-smooth calibration errors. These, overall, impart spectral structure on smooth foregrounds, leading to foreground power leakage into the EoR window. In this thesis we explored the use of fringe rate filters (Parsons et al., 2016) as a mean to mitigate calibration errors resulting from the effects of mutual coupling and the use of an incomplete sky model during calibration. We found that the use of a simple notch filter mitigates calibration errors reducing the foreground power leakage into the EoR window by a factor of ∼ 102. Thyagarajan et al. (2018) proposed the use of closure phase quantities as a means to detect the 21 cm signal, which has the advantage of being independent (to first order) from calibration errors and, therefore, bypasses the need for accurate calibration. In this thesis, we explore the impact of primary beam patterns affected by mutual coupling on the closure phase. We found that primary beams affected by mutual coupling lead to a leakage of foreground power into the EoR window, which can be up to ∼ 104 times and is mainly caused by the unsmooth spectral structure primary of primary beam sidelobes affected by mutual coupling. This power leakage was confined to k < 0.3 pseudo h Mpc−1. Lastly, we also proposed and demonstrated an analysis technique that can be used to derive a flux scale correction in post-calibrated HERA data. We found that after applying flux scale correction to calibrated HERA data, the bandpass error reduces significantly, with an improvement of 6%. The derived flux scale correction was antenna-independent, and it can be applied to fix the overall visibility spectrum scale of H4C data post-calibration in a fashion similar to Jacobs et al. (2013). , Thesis (PhD) -- Faculty of Science, Physics and Electronics, 2024

- Description: In this thesis, I examine anonymous testimony in both offline (face-to-face) and online (internet and social media) interactions and the epistemic concerns it raises in relation to belief, knowledge, justification, and normative assessments of assertions. I discuss anonymous testimony as involving a relation between the hearer and the content of the testimony in comparison to ordinary cases where the speaker of an assertion is known. In anonymous testimony, the hearer has the burden of epistemic responsibility to arrive at a testimonial belief or arguably acceptance. The hearer is also accountable for the anonymous testimony in the event of re-assertion. I also assess the norms of assertion for anonymous testimony and argue that knowledge, truth, and belief norms that apply in cases where the speaker is known should not be applied to cases of anonymous speakers. Epistemologists have paid little attention to anonymous testimony and its implications on the norms of interaction. This is a study in the epistemology of testimony and it aims at providing further understanding of the epistemic responsibility of hearers of anonymous testimony. In Chapter One, I argue that anonymous testimony can be appropriately described as testimony; where the properties of an assertion to induce belief in the hearer are sufficient to describe the assertion as testimony. I examine the kinds of anonymity and the burden of epistemic responsibility for the hearer. I introduce basically anonymous testimony in offline and online contexts of interaction. A basically anonymous testimony occurs where, at the instance of receiving testimony and making an epistemic decision on it, the speaker is unidentifiable to the hearer. In Chapter Two, I discuss the kinds of epistemic attitudes hearers may have when they receive anonymous testimony. I discuss reductionism, antireductionism, and entitlement theory as accounts of the justification for believing testimony. I argue that acceptance is the appropriate attitude and the entitlement theory provides a basis for accepting anonymous testimony. I also argue that practical reasons are a sufficient to accept anonymous testimony. Also, I discuss the possibility that a hearer of anonymous testimony can make a wrongful presumption by assigning an identity to a person as the speaker of an anonymous testimony. This can cause harm to the ‘person’ of the presumed speaker such as an unwarranted credibility assessment of the person by other people in the community. I also argue that making a credibility assessment of a presumed speaker constitutes harm to a proper epistemic assessment of the content. In Chapter Three, I discuss the possibility of trust relations between an anonymous speaker and a hearer. I argue that the hearer is solely responsible for making an epistemic decision from anonymous testimony. I argue that anonymous testimony can be relevant to a hearer given the value of its content. In Chapter Four, I discuss the applicability of knowledge, truth, belief, reasonable to believe and supportive reasons norms for the re-assertion of anonymous testimony. Hence, I argue that the supportive reasons norm, which acknowledges acceptance of an assertion, the relevance of contexts, and admits both epistemic and practical reasons to make an assertion, should guide the re-assertion of anonymous testimony. I also argue that a hearer should be epistemically conscientiousness for responsible re-assertion of received anonymous testimony. , Thesis (PhD) -- Faculty of Humanities, Philosophy, 2023

- Description: The focus of this study was to investigate pedagogical practices of English First Additional Language educators in teaching Grade 12 short stories. An interpretive qualitative case study of three educators from three high schools in Chris Hani West district, in Eastern Cape were purposefully selected. Lesson observations, semi-structured interviews, and document analysis (lesson plans) with three English FAL educators were used to collect data. Shulman’s (1986) Pedagogical Content Knowledge was used as the theoretical framework and analytical tool for the study. Data revealed ineffective teaching strategies and on-the-surface subject matter knowledge that hampers the critical teaching of short stories. It also showed that educators have limited knowledge of learners’ learning difficulties and how to address them. The study recommends less teacher talk that was observed in many classes, to be replaced by extended discussions on the part of the learners. Educators should establish a variety of contemporary teaching strategies which put critical thinking and active learning before examination preparation. Lastly, educators, in their teaching of short stories, should consult various resources and attend content workshops to keep subject knowledge up to date. , Thesis (MEd) -- Faculty of Humanities, Study of Englishes of Africa, 2023

Effect of a school-based health intervention on the non-communicable disease risk status of schoolchildren from disadvantaged communities

- Description: Background: Non-communicable diseases (NCDs) such as cardiovascular diseases (CVDs) and dyslipidaemia are a global public health concern, but more so in low- income countries where the underprivileged are exposed to unhealthy lifestyle practices with limited access to primary health care. Poor dietary habits and physical inactivity have also led to the unprecedented rise of NCD risk factors among school- aged children, which places them at greater risk of disease later in life. These NCDs are largely driven by obesity which has continued to rise in sub-Saharan Africa. However, high levels of undernutrition (such as stunting, underweight and wasting) among children are also present, thereby translating to a dual burden of malnutrition. Promoting regular physical activity (PA) among children is crucial for the health of future generations as it assists in weight reduction, improves insulin sensitivity, reduces blood pressure and is associated with good health and wellbeing. However, physical education (PE), the most obvious vehicle to develop the motor abilities of children, creating opportunities for their sports skills development and educating learners about the importance of PA as a lifestyle, has long been overlooked since the transformation of the South African school curriculum. Furthermore, many in-service PE teachers were not trained to teach the new multi-disciplinary Life Skills and Life Orientation subjects, of which PE forms a small part. Evidence shows that many PE teachers lack the content knowledge and practical skills to implement the subject, which raises the question of how many children, especially those in low-income communities, are participating in quality PE needed to foster healthy lifestyles and prevent the risk of NCDs. Therefore, this study aimed to investigate the effect of a 20- week school-based health intervention on NCD risk factors of primary schoolchildren from low-income schools in Gqeberha, South Africa. Methods: A cluster randomised control trial was used to test a 20-week intervention, which included three components, namely [1] the KaziKidz toolkit (comprised of pre- prepared PE, health, hygiene and nutrition lessons, equipment for PE, and painted games) [2] a PE coach (human movement science graduate to assist teachers) and [3]two 90-min training workshops. Eight schools were randomly selected to participatein the study: four intervention schools received the KaziKidz toolkit, while the externalsupport components were staggered across three intervention schools, and the Chapter 1: Introduction 2 remaining four schools served as the control group. Altogether 961 children (491 boys and 511 girls) from grades 4 to 6 (8 - 13 years old, M=10.88±1.19 yrs) participated In the study. Demographic information and socio-economic status were captured with a questionnaire. Further measures included height, weight, waist circumference, blood pressure, glycated haemoglobin, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, accelerometer-based PA and cardiorespiratory fitness (CRF). Results: Cross-sectional baseline data showed that 43.1% of the sample presented with at least one NCD risk factor, and 17% presented with an elevated clustered risk score (CRS). In addition, higher CRF and moderate to vigorous PA (MVPA) were associated with a lowered CRS whereby an elevated CRS was halved for every 49 min increase in MVPA (95% CI 27 - 224) or every 2.17 ml/kg/min increase in CRF, as determined via estimated VO2max (95% CI 1.66 - 3.12). Overall, 13% of the cohort were underweight, 12% overweight, 7% obese, and 64% engaged in an average of 60 min MVPA per day. The results also identified an inverse association between body mass index categories and the total duration of MVPA achieved per day as children categorised as underweight to normal‐weight (boys: OR = 3.89, 95% CI: 2.18 - 6.93; girls: OR =1.78, 95% CI: 1.13 - 2.80) were more likely to engage in 60 min per day of MVPA than overweight to obese children. Finally, the school-based health intervention results revealed improvements in children's NCD risk factors and increased MVPA levels when the intervention conditions included the workshops and, in some cases, the PE coach. The KaziKidz toolkit (on its own) showed little to no improvements in NCD risk factors and MVPA levels. Conclusion: School-based health interventions have the potential to improve the NCD risk factors of children attending low-income schools in South Africa. These findings also add to our understanding of implementing interventions in settings where teachers are not sufficiently trained to teach PE. Therefore, school-based health interventions, including a toolkit, should be accompanied by workshops to equip educators with the necessary tools to confidently facilitate PE lessons and integrate a range of PE activities into their classrooms. Future research is recommended to determine the long-term sustainability of school-based health interventions and the long-term post-intervention impact on NCD risk factors. , Thesis (PhD) -- Faculty of Health Science, Department of Human Movement Science, 2023

- Description: In their efforts for a place in the economy, many South African women have embraced opportunities in the informal sector such as selling products for big Multi-Level Marketers (MLMs), who generally operate on a pyramid structure of commissions. This qualitative study investigates the meanings African women engaged in MLMs in Makhanda make of such work and examines how they construct notions of progress and success through their social media practices. The study was conducted in the strictest lockdown period and pioneered a research method that used Zoom to facilitate screen sharing on mobile phones to create an online version of the scroll-back method for Facebook. As expected for women working in a society increasingly integrated in a global neoliberal order, many of the meanings the women construct are rooted in neoliberal discourses that celebrate hyper-individualism and competition. This firstly includes constructing success through personal stories of self-appreciation, through which these women embody the MLM’s brand, while simultaneously improving their position in the market as sellers. Secondly, the women invest considerable effort on social media in constructing MLM work as epitomising stability in the context of the growing precarity that characterises their everyday lives. However, other meanings draw on the local African context. Here the women make sense of the inequalities that characterise the MLM pyramid structures, by constructing top players in the upline as a symbolic vanguard trailblazing freedom from a racist past through showcasing paths out of poverty. More interestingly, success is constructed as both resulting from and serving collective ways of being rooted in the discourse of African humanism. Here success is recognised as emerging from dense place-based networks in the neighbourhood built on trust and obligation, now replicated on social media. In conclusion, the study speculates that the worlds of meaning facilitated by MLMs might provide ways for neoliberal and traditional discourses to find points of synergy, and so serve as entry points into a neoliberal order that interestingly nevertheless draws on communal cultures of obligation and patronage. , Thesis (MA) -- Faculty of Humanities, School of Journalism and Media Studies, 2022

- Description: In their efforts for a place in the economy, many South African women have embraced opportunities in the informal sector such as selling products for big Multi-Level Marketers (MLMs), who generally operate on a pyramid structure of commissions. This qualitative study investigates the meanings African women engaged in MLMs in Makhanda make of such work and examines how they construct notions of progress and success through their social media practices. The study was conducted in the strictest lockdown period and pioneered a research method that used Zoom to facilitate screen sharing on mobile phones to create an online version of the scroll-back method for Facebook. As expected for women working in a society increasingly integrated in a global neoliberal order, many of the meanings the women construct are rooted in neoliberal discourses that celebrate hyper-individualism and competition. This firstly includes constructing success through personal stories of self-appreciation, through which these women embody the MLM’s brand, while simultaneously improving their position in the market as sellers. Secondly, the women invest considerable effort on social media in constructing MLM work as epitomising stability in the context of the growing precarity that characterises their everyday lives. However, other meanings draw on the local African context. Here the women make sense of the inequalities that characterise the MLM pyramid structures, by constructing top players in the upline as a symbolic vanguard trailblazing freedom from a racist past through showcasing paths out of poverty. More interestingly, success is constructed as both resulting from and serving collective ways of being rooted in the discourse of African humanism. Here success is recognised as emerging from dense place-based networks in the neighbourhood built on trust and obligation, now replicated on social media. In conclusion, the study speculates that the worlds of meaning facilitated by MLMs might provide ways for neoliberal and traditional discourses to find points of synergy, and so serve as entry points into a neoliberal order that interestingly nevertheless draws on communal cultures of obligation and patronage. , Thesis (MA) -- Faculty of Humanities, School of Journalism and Media Studies, 2022

- Description: In light of changing health needs, health information systems are presented with a plethora of challenges. For instance, the rise of COVID-19 in the past year has led to the discourse on the strength of current health systems to support health needs and the readiness for the National Health Insurance in South Africa. In addition to operating in resource-constrained environments, the lack of synchrony between health information systems across health facilities led to the fragmentation of health information and diminished access to quality healthcare. This research, following the Design Science Research Methodology (DSRM) process, developed an IT governance conceptual framework (HISIG-CF), to inform the interoperability of health information systems. The HISIG-CF is developed from literature and qualitative data collected using an expert reviews method from practitioners in the healthcare sector who evaluated the constructs of the HISIG-CF. Thematic analysis and hermeneutics were used to analyse and interpret the data. The results revealed a need for more guidance to inform interoperability interventions and strengthen current health information systems. The contribution of this study is the HISIG-CF which is deemed relevant and potentially fit-for-purpose to improve health information systems interoperability within the healthcare sector in South Africa. , Thesis (MCom) -- Faculty of Commerce, Department of Information Systems, 2022

- Description: Deteriorating environmental water quality is one of the complex challenges in South Africa that threaten freshwater ecosystem health and functionality. An emerging concern is the contestation of water quality regulatory instruments such as standards in water use licences (WUL), and the resource quality objectives. In the Vaal Barrage catchment where this study was undertaken these contestations were evident, suggesting the need for both technical and social solutions to water quality changes in socio-ecological systems. The Vaal Barrage catchment within the lower section of the Upper Vaal is a highly developed, urbanised, and complex catchment supporting and contributing to the social-economic development of Gauteng Province and the entire country, as the Upper Vaal contribute 20% to the Gross Domestic Product of South Africa. This study explores the motivations for stakeholders’ contestations of water quality regulatory instruments in order to contribute to ways in which water resource users and regulators can collaboratively address water quality challenges in the Vaal Barrage catchment. The study also explores water quality scenarios and their ecological and management implications. Document analysis, participant observations and a semi-structured questionnaire were deployed to explore stakeholders’ motivations, values, and perceptions of the water quality regulatory instruments. The results were triangulated to gain better insights into research participants responses. To explore water quality management scenarios, the study applied a water quality systems assessment model Decision Support System (DSS). The DSS was recently developed as part of a bigger project within the Vaal Barrage catchment. Regarding stakeholders’ motivation for contesting water quality regulatory instruments in the catchment, the results revealed a perceived lack of scientific credibility and defensibility in the processes used for deriving standards in WUL, a lack of transparent linkage between the WUL and resource quality objectives, and the increased need for stakeholder engagement in the resource quality objective formulation process. Furthermore, the study revealed punitive measures, education and awareness, self-regulation as mechanisms to encourage compliance. The applied DSS results showed that high nutrient loads, sulphate and total dissolved solids sourced from upstream catchments contribute to water quality deterioration in the Vaal Barrage catchment. The results also showed that the Vaal Barrage catchment could not host additional licence emitters because of TDS, phosphate and nitrate levels, which pose a serious risk to the ecology of the Vaal Barrage catchment, indicating that system had exceeded its assimilative capacity for critical water quality variables. Lastly, the results evidenced the need for collaborative action by the waste emitters within the Vaal Barrage catchment, particularly collaboration between upstream and downstream waste emitters. The study has far-reaching implications for water quality management in South Africa. These include i) the need for transparent and open processes and methods for deriving standards in water use licence, ii) the need for a water quality DSS that recognises catchment hydrological complexity in deriving standards in WUL, and for linking WUL and Resource Quality Objectives (RQOs), iii) collaboration between resources users, and between the resources users and the regulators to bring pollution to acceptable levels and iv) both social and technical solutions are necessary for managing water quality challenge, particularly in a highly developed catchment such as the Vaal Barrage system. , Thesis (MSc) -- Faculty of Science, Institute for Water Research, 2022

- Description: In an effort to move away from Apartheid and its evils -South Africa and South Africans have committed to a shared moral project -the Rainbow Nation-Building Project (RNP); a project that confers certain moral duties and responsibilities upon its citizens, including a joint commitment to robust inclusivity, equality, and unity. Importantly, however, our environments –be they physical, social, or psychological –are such that they (actively or passively) obscure our awareness of some morally relevant facts about our society, and thereby hinder us as moral agents and therefore threaten our abilities to fulfil our moral project and commitment.What does it mean for us -a society ostensibly committed to the RNP -to be plagued by racism, sexism, queerphobia and xenophobia? What is it that contributes to our complicity regarding social practices and ideas that we would otherwise find morally objectionable? What does it say about our commitment to our publicly-exalted ideals and values (of inclusivity, diversity, reconciliation, justice, and unity) when we are unwittingly complicit in the marginalisation and social exclusion of members of our society? And how can institutions such as universities work to overcome this?In this work, I argue that the obscuring of, and failure to perceive, morally relevant facts that call on us for ethical attention and/or action -a phenomenon I refer to as ‘moral blindness’ -is responsible for at least some of our behaviours and practices that run contrary to our moral ambitions; and therefore has profound implications for us as moral agents and our ability to succeed in our moral goals. Moral blindness, then, is both an epistemic and ethical concern that enables socially unjust systems to perpetuate themselves; and is thus a threat toallmoral projects.I argue that, for South Africa, much of what can be identified as moral blindness is the direct result of the shifting and conflicting socio-cultural conditions the nation finds itself liminally caught amidst in its transition from its Apartheid past and towards its promised inclusive Rainbow Nation future. Commitment to the RNP, I argue, involves a self-transformation and habituation of certain supportive virtues on the part of South Africans to become the kinds of people who are compatible with the Rainbowist society -whom I call Rainbow Citizens. But this self-transformation itself is also a moral project, and therefore subject to the threat that moral blindness presents, and so too can be failed. If all this is true, then it seems that if we do not take moral blindness seriously, we could ultimately fail to become South African. , Thesis (MA) -- Faculty of Humanities, Philosophy, 2021

- Description: This treatise begins with an interest in the architectural typology of the Vihara - the Buddhist monastery. Through an investigation of the monastery type, an appropriate theoretical lens is identified. The core architectural function of the monastery is the creation of sacred space. Four constituent elements of sacred space are identified and are taken throughout the treatise as a set of values through which investigation is directed and design decisions are made. Through investigation of the typical monastery context, it becomes possible to identify an appropriate site. An urban farmland in Cape Town, in the heart of the South African Buddhist community is identified. Design drivers emerge through researching mapping and visiting the site. It is through a synthesis of all the information learned, that a single, core gesture is developed. The aim is to design a building to serve the local monastic Buddhist community. , Thesis (MA) -- Faculty of Engineering, the Built Environment, and Technology, 2020

- Description: The aim of this study was to investigate causes of repeated admissions of mentally ill women in a psychiatric institution. The study was conducted in the Nelson Mandela Bay Municipality, which comprises Port Elizabeth, Despatch and Uitenhage. A focus group and unstructured interviews were used to collect data. The focus group consisted of 9 participants, which comprised 7 family members or caregivers of mentally ill women with repeated admissions in a psychiatric institution and 2 professionals, a psychiatric social worker and a doctor. Since this is a relatively new area of study, thus a qualitative research method was used for the researcher to interact with participants in their natural habitat. Snowball sampling was used to locate members of the population. Literature review has demonstrated that continued exposure to abuse has a negative effect on the mental health of the survivor. Some of the women were mentally fit before the abuse, but due to abuse at the hands of their husbands or partners, and sometimes families, became mentally ill. Neglect, lack of understanding of mental illness, defaulting of medication and lack of trained psychiatric professionals in the Nelson Mandela Bay Municipality were found to be the most common reasons that led to repeated admissions. , Thesis (MSoc Sci) (Social Work) -- University of Fort Hare, 2021
