Doctor of Philosophy ADU, Frank Graduate School of Business Administration THESIS: Studies on domestic resource mobilization in Ghana This thesis examined the dynamics of domestic resource mobilization in Ghana. Four empirical essays revealed an elastic tax system; asymmetric impact of taxation on distribution; a low threshold between domestic debt and financial sector development. Reverse causality between revenue systems and good governance and related policies are addressed in the thesis. Supervisor: Professor P Alagidede ASAMOAH, Michael Effah Graduate School of Business Administration THESIS: Essays on Private Capital Flows and Real sector growth in Africa The thesis explored four empirical themes on the interplay between private capital flows, financial development, institutions, and real sector growth in Africa. The results revealed the existence of thresholds in the capital flows-real sector relationship, as well as the impact of volatility on capital flows. Financial development and robust institutions matter for economic growth, while managed capital flows improves economic performance. Supervisor: Professor P Alagidede AYISI-BOATENG, George Graduate School of Business Administration THESIS: Political regimes and economic development in Ghana’s Fourth Republic The thesis contributes to the role of political regimes in Ghana’s fourth republic (19932020) using the critical realist research framework. The study argues that although significant amount of sound policies have been written on paper, implementation challenges have been the Achilles’ heels of Ghana. In the economic sphere, the study identified a plethora of policy slippages in relation to job creation and entrepreneurial development and recommends policy options for improving the management of the economy. Supervisor: Professor P Alagidede BORDISS, Bradley John Economics THESIS: Shaping monentary policy and development in South Africa: the role of Jack Holloway and Andries Bruwer, from 1914 to 1950 Between 1914 and 1950, the international gold standard and laissez-faire system broke down. This dissertation examines a South African debate which raged between two internationally trained economists, one trained in Britain and the other in the United 5

States. Jack Holloway defended the global gold standard. Andries Bruwer advocated leaving it, and proposed state-led national development. This thesis examines these developments in the history of economic thought and policy in the interwar period, mindful of how it relates to today’s debate between free trade inflation targeters and those in favour of national development. Supervisor: Professor M Padayachee BYARUHANGA, Bonaventure Wits School of Governance THESIS: Examining the role of Corporate Governance in Microfinance Institution operations in Uganda: a case of the Bushenyi District Bonaventure Byaruhanga examines the role of corporate governance in Microfinance Institution (MFI) operations in Uganda. He identified that properly instituted governance structures, good governance practices; appropriate legislative and policy frameworks, are vital in MFI operations. This study in rural microfinance governance, significantly contributes to new knowledge in financial inclusion and contributes to literature on corporate governance by establishing the importance of control and governance mechanisms in MFIs. Supervisor: Professor T Mogale CHEN, Yu-Jen Graduate School of Business Administration THESIS: Uncovering Selected Antecedents of Collective Intelligence of Strategic Project Teams Leaders’ capability to harness small intelligent teams profoundly impact the competitiveness of their organisations. Owing to this reason, the study of collective intelligence has emerged as a notable interdisciplinary research agenda in recent years. This study assessed the collective intelligence of small teams with a total number of 406 participants. The findings suggested that three cognitive-behavioural clusters, viz. resource acquisition and utilisation, strategic thinking, and team members exchange directly impact the quality of the collective intelligence of small teams. Supervisor: Professor B Urban CHUENE, Palesa Betty Information Systems THESIS: An integrated model for information technology servitization adoption in South African state-owned enterprises Information technology servitization is still in its infancy, especially in South African state-owned enterprises. The thesis explains the determinants which are significant in the adoption process. The study triangulated three theoretical lenses to inform the integrated model for the adoption of IT servitization in South African SOEs. Supervisor: Professor M Kekwaletswe DLADLA, Pholile Economics THESIS: Sources of risk in insurance markets The study focuses on insurance risk management in select developed and emerging market economies, the impact of macroeconomic factors on insurance and bank risk and the linkages between banks and insurances. Insurance and banking contributed, on average 7% to global GDP in 2017 as such this study benefits policy-makers, regulators and the finance sector. Supervisor: Professor L Mncube

FEELA, Tshepo Graduate School of Business Administration THESIS: Determinants of successful coopetition between SMEs in SADC countries implications for strategy and firm performance The thesis explores the benefit of coopetition (competing and collaborating at the same time with other firms) amongst SMEs in the SADC region using principles of microeconomics. The results indicate that coopetition leads to better firm performance and innovation which are some of the key drivers in economic growth. The aim is to provide SMEs with new strategies to strengthen their position in the market and compete on a global scale. Supervisors: Dr T Mthanti and Professor K Ojah GAWAYA, Rose Wits School of Governance THESIS: Access to aid: case studies of women’s organizations in South Africa and Uganda This study explores five women’s organisations that are beneficiaries of aid in South Africa and Uganda. Women’s organisations largely remain on the margins of grantmaking, struggling to engage competitively in the fast-evolving donor environment. Dr Gawaya critically evaluates both grant-makers and beneficiaries, the values embedded in aid structures and the power that influences access and the utilisation of aid. The work is original and based on her own experience and political contribution to women’s organisations in Ghana and the aid space. Supervisor: Dr D Miller GWALA, Sizwe Wits School of Governance THESIS: A secure cyberspace as a strategic focus point in governing the internet ecosystem: the case of the South African public sector Cybersecurity has been identified by the Internet Governance Forum as a highly strategic focus area for its member-states. This research project explored and reported on the extent to which South Africa has been able to govern the Internet Ecosystem in line with global and regional guidelines. It focused on South African public-sector organisations. The study applied Social Network Theory and proposes a Cybersecurity Governance Framework to be followed by government when rolling out cybersecurity controls in line with international standards. Supervisor: Dr A Van Nieuwkerk JARAVAZA, Divaries Cosmas Graduate School of Business Administration THESIS: Culture, Contraceptive Attitudes and Advertising Perceptions: the case of rural Zimbabwe Divaries Jaravaza’s thesis sought to advance marketing science through examining information processing, cultural and behavioral responses to reproductive health advertising by rural consumers. He established that resultant self-conservation and religiosity are positively related to rural women’s contraceptive attitudes. The study points to heterogeneity of subsistence women’s cognitive and effective perceptions of contraceptive poster advertisements in rural markets. This knowledge will aid in reshaping advertising research and practice and provides unique cues for poster ads targeting rural consumers in subsistence markets. Supervisors: Dr F Saruchera and Professor S Burgess

KIM, Young Jae Law THESIS: At crossroads of international development law, international human rights law, and international investment law - reflection on the right to development in the exercise of expropriation This thesis considers the conceptual intersection between international investment law, human rights law and development law, provided by the right to sustainable development. Through a case study of expropriation of investment, it shows how the right to sustainable development provides an entry portal for human rights into international investment law. Supervisor: Professor M Pieterse KUMAH, Seyram Pearl Graduate School of Business Administration THESIS: Cryptocurrencies and African Financial Markets: integration, risk analysis, and diversification This thesis investigates the nexus between cryptocurrencies and traditional asset classes in African financial markets. Four empirical essays reveal varying levels of integration between cryptocurrencies and African financial markets; no clear market leader or follower; time-varying transmission of volatility shocks; and opportunities for hedging. Bi-directional causality among cryptocurrencies and African financial assets, and related policies are addressed in the thesis. Supervisor: Dr J Mensah MABVIRAKARE, Antony Business Science THESIS: Bus service quality and its relationship with cross boarder passengers’ satisfaction and referral intention in Zimbabwe The study tested conceptual model of the mediating influence of cross boarder passengers’ satisfaction and continuance usage on the relationship between Bus Service Quality (BUSQUAL) and bus referral intention. The findings reveal that bus firms take for granted Non-Passenger Travelling Services (NTS) which generate more revenue if properly offered in a coordinated manner. The findings indicate that the provision of Bus Service Quality elements as expected by the passengers have a direct influence on passengers’ satisfaction, continuance usage intention, and bus referral intention. Supervisors: Professor R Chinomona and Dr N Chiliya MANDEVERE, Melody Graduate School of Business Administration THESIS: An analysis of the effectiveness of Corporate Social Responsibility in the mining sector: a comparative study of South Africa and Zimbabwe mining companies There is concern over the sustainability of CSR undertaken and the motives behind mining companies in Zimbabwe. This comparative study, utilised multiple case studies between Zimbabwe and South Africa’s mining sectors on the effectiveness of CSR. The findings indicated that legislation in South Africa, unlike Zimbabwe, encourages stakeholder inclusion leading to project sustainability and CSR effectiveness. The study addresses the need for an Africanised agenda, which prioritises legal issues, with social impact as the driving force. Supervisor: Dr R Horne

MNGUNI, Mphikeleli Matthew Wits School of Governance THESIS: Government’s Strategic Interventions to Optimise the Performance of Creative and Cultural Industries: a case study of SMMEs in Mpumalanga Province The cultural and creative sector is increasingly seen as a sector to help in reducing the high levels of unemployment, inequality, and poverty in South Africa. This study attempts to understand, through the artists’ perspectives, the government’s interventions to optimise the performance of the Small, Micro and Medium Enterprises (SMMEs) within the Cultural and Creative Industries (CCIs) in South Africa. The study explores service quality attributes, the artists’ satisfaction, and the performance of the creative SMMEs in Mpumalanga province. Supervisors: Professor P Pillay and Dr M Muller MONDI, Lumkile Patriarch Economics THESIS: A long walk to a Just Energy Transition: the political economy of the restructuring of Eskom 1985 and beyond The thesis explores the development of the troubled South African state electrical parastatal, Eskom, and provides a window into understanding the policy trajectory and decision making of the South African government as it deals with the competing challenges of climate change, business interests and a rural black population long denied electricity due to the injustice of apartheid. Supervisor: Professor M Padayachee MPHAHLELE, Matuku Wits School of Governance THESIS: Capacity development of service delivery structures and programmes in Bojanala Platinum District Municipality The candidate’s PhD thesis examines challenges related to the use of capacity development resources and programmes tied to service delivery, and ways in which they can be overcome. His study focuses on the Bojanala Platinum District Municipality (BPDM) in the North West Province - a Centre of the extractive economy with a highly heterogenous and mobile population and high levels of inequality. Findings suggest that socio-political resilience and administrative synergy are key enablers in the enhancement of service delivery. Supervisor: Dr E McCandless MUREKACHIRO, Dennis Graduate School of Business Administration THESIS: Stock price prediction in Sub-Saharan Africa The objectives of this thesis are to predict the stock prices of 10 selected African countries and SP500 stock markets’ prices using deep learning prediction models (LSTM, RNN, GRU, BLSTM, BRNN, BGRU) and statistical GAM and to determine the factors that influence stock prices. Empirical results show evidence of return predictability of stock markets’ prices with DNN and GAM prediction models producing the highest prediction accuracy of +96%. Exchange rate has the most significant impact on stock price movements. Supervisor: Professor T Mokoaleli-Mokoteli

MUSENDAME, Thabiso Jeremiah Business Science THESIS: Management effects on company performance: a mixed methods study of the South African rubber industry With the general decline of South African manufacturing industry, the thesis sought to investigate the reliability and validity of a globally tested, ‘universal model’ of the effectiveness of management practice on company performance in the Rubber Industry. The thesis found that both universal management practices and context were crucial in performance maximization. Supervisor: Professor D Coldwell NETSHITOMBONI, Nnzeni Economics THESIS: The industrial development corporation under apartheid: financing industrialisation in South Africa 1940-1990 For a thesis which shows that the Industrial Development Corporation played in integral part in financing the industrialisation of South Africa from 1940 to the mid-1970s in partnership with the state but strayed away from developmentalism to support security-inspired projects thereafter. Supervisors: Professor W Freund and Dr N Pons-Vignon OLALEYE, Oluwole Wits School of Governance THESIS: The nexus between performance information use and service delivery in South African local municipalities This thesis examines the direct effects of performance information use on service delivery within South African municipalities. In this regard, the study investigates the extent to which this relationship is influenced by six different organisational properties: managerial quality, external actors, rational culture, developmental culture, hierarchical culture and group culture as constructs of organisation culture. Supervisors: Professor P Pillay and Dr M Muller OMANE-ADJEPONG, Maurice Graduate School of Business Administration THESIS: Essays on Cryptocurrencies and Traditional Assets in Emerging Market Economies: Dynamic Modelling, Connectedness and Spillovers The essays allay the fears of investors and market participants, and reveals for the first time that the cryptocurrency market is less influenced by existing highly integrated instruments, and has little effect on emerging markets, and consequently poses, for now, a negligible danger. The insights gleaned open doors for policymakers to properly fine-tune their economies to maximise the upside potential presented by this asset class and minimise the downside risks, in the light of the role of cryptocurrencies so far. Supervisor: Professor P Alagidede

PATEL, Riyaaz Muhommed Business Science THESIS: Developing and testing a framework for digital channel adoption in emerging markets Applying qualitative and quantitative methods, this thesis provides a synthesis of theoretical perspectives to derive and test a model of digital adoption of mobile applications. The model is tested using samples from India and South Africa, providing insights relevant to emerging market contexts with digital markets of growing importance. Supervisor: Professor C Callaghan SEBOPA, Caroline Boitumelo Business Science THESIS: Building brand commitment from the internal brand management and employee based brand equity factors Three models were integrated to examine the impact of Famous Brand’s internal brand management practices on brand commitment through employee satisfaction and Employee-Based Brand Equity (EBBE). Internal communication, role clarity, management support and rewards influenced employee satisfaction, which impacted brand citizenship behaviour, brand endorsements and brand allegiance. These drove brand commitment. Supervisor: Professor H Duh SEPURU, Thabo Dominicah Wits School of Governance THESIS: Access to pro-poor Education benefits for urban parents in democratic South Africa This study explores why poverty impedes equitable access to relatively free public education in former whites-only suburban schools. In South Africa, poverty impedes equitable access to public education because the system is unable to maintain a heterogeneous class mix amongst residents. The study shows that the system differentiates residential areas and schooling on the basis of poverty and affluence, which in turn perpetuates poverty and inequality. Policy action should focus on how the quality of education in poor schools can be enhanced. Supervisors: Dr A Mc Lennan and Professor P Pillay SIDDIQUI, Ammar Ahmed Marketing THESIS: Impact of firm-level characteristics and international marketing strategies on export performance of SME’s in South Africa The thesis identifies and examined the impact of key determinants on optimal and superior export performance of SMEs in South Africa. The findings indicate that optimal export performance was significantly driven by an organization’s characteristics, market competencies, environmental elements, financial and marketing strategies while superior export performance was induced by employees’ personality traits and managerial attributes. Supervisors: Professor R Chinomona and Dr N Chiliya

VINTI, Clive Law THESIS: Hydrocolonisation in the Lesotho highlands water treaty: legitimate treaty or murky waters? For a thesis which assesses whether the Treaty on the Lesotho Highlands Water Project complies with the key underlying transboundary water principles, with a specific focus on sustainable development, equitable and reasonable utilization and permanent sovereignty over natural resources, which address the anticipated conflict of uses. Supervisor: Professor T Murombo WERBELOFF, Merle Wits School of Governance THESIS: The role of Statistical Numeracy in Computational Models of Risky Choice Numeracy is a strong predictor of general decision-making skill. However, the commonly used model assumes complete cognitive competence of the decision maker, and statistical numeracy is not considered directly in descriptive models of risky choice. These models are nevertheless used to assess individuals’ economic welfare. This study proposes a numeracy-based modification to the models, citing the nudging and boosting policy initiatives of the behavioural economics literature as potential solutions to the presence of low numeracy and its effects on risky choice behaviour. Supervisors: Dr M Muller and Professor P Pillay

FACULTY OF ENGINEERING AND THE BUILT ENVIRONMENT DEAN: PROFESSOR IR JANDRELL BSc(Eng) GDE PhD (Witwatersrand) IntPE(SA) PrEng FSAAE FSAIEE SMIEEE Doctor of Philosophy BRADLEY, Ryan Anthony School of Civil and Environmental Engineering THESIS: Earth brick shell housing in South Africa: structural and performance considerations The thesis is a detailed and thorough study of masonry catenary domes and vaults. To optimize the design, numerous experiments were performed and theoretical concepts and techniques were developed in the fields of wind loading, thermal loading and numerical methods for pure compression structures. A greater understanding of durability, the optimization of forms and the development of design techniques to improve the performance of masonry shell structures were achieved. Supervisor: Professor M Gohnert CARLSON, Craig Stuart School of Electrical and Information Engineering THESIS: The Sound of Ink Tattoos and the art of tattooage have been around for thousands of years. Nevertheless, scientific studies on the physics of tattoo ink were lacking. This PhD research concentrated on understanding the interaction of tattoo ink with ultrasound. It was found that black ink particles are hydrophobic and undergo transient nucleation. They may be forced to grow explosively with the aide of an ultrasound pulse. Furthermore, the inking of skin was found to result in unique artefacts on diagnostic ultrasound images. The findings from this study have applications in tattoo detection and modification, but also in the development of new diagnostic and therapeutic agents and even in sharp cutting techniques. Supervisor: Professor M Postema DE MELLO KOCH, Ellen School of Electrical and Information Engineering THESIS: A coarse graining perspective of deep learning The remarkable success of deep learning at numerous tasks in various applications is well appreciated in practice, but theoretical explanations for how deep learning works are in their infancy. The candidate established the link in a quantitative way of the renormalization group and deep learning. Such a link would give a possible starting point from which to develop a theoretical framework for deep learning by exploiting the rich theory of renormalization group. Supervisor: Professor L Cheng

ENWEREUZOH, Uzochukwu Onyinyechukwu School of Chemical and Metallurgical Engineering THESIS: Algae Biomass cultivation in fish farm effluent for biodiesel production Nutrients in fish farm wastewater were exploited for the cultivation of low-cost microalgae biomass for biodiesel production as a substitute to expensive purchased fertilizer. Microalgae species in fish farm wastewater accumulated desirable compounds suitable for biodiesel production, eliminated the cost of fertilizer and also cleaned the fish farm wastewater. Supervisors: Dr K Harding and Dr M Low KAMUDYARIWA, Xebiso Blessing School of Construction Economics and Management THESIS: Changing procurement culture to enable the successful adoption of collaborative practices in construction: a model for client change As procurement challenges continue to plague construction, the research focused on the role of clients in enacting change from the more traditional procurement common in industry to a collaborative culture of construction. Using the case study of Wits Campus Planning and Development, the research developed a model for clientinitiated change that can improve project outcomes. Supervisor: Professor D Root MAPONGA, Oliver Josiah School of Chemical and Metallurgical Engineering THESIS: A geometallugical characterisation of the Hwange coalfield: how does coal formation affect coal exploitation? Coal is a heterogeneous substance whose qualities were controlled by conditions occurring during its origin in various wet and dry swamps and subsequent formation. This thesis explored the conditions that gave rise to the coals found in Hwange coalfield, Zimbabwe and established the reasons for the different and highly specific geometallurgical and energy-related applications. Supervisors: Dr S Bada, Dr N Wagner and Professor R Falcon MULAUDZI, Fulufhelo Marandela Lloyd School of Chemical and Metallurgical Engineering THESIS: Mechanistic study of metal dusting corrosion for austenitic alloys in the petrochemical industry Metal dusting was studied in a custom-built rig comparing iron- and nickel-based alloys, to identify the most resistant alloy. Alloys with protective oxide scales lasted longer. Ni-based alloys suffered less, and the best alloy, 693, was used to successfully protect 304 stainless steels for longer times. Supervisor: Professor L Cornish OBIKO, Japheth Oirere School of Chemical and Metallurgical Engineering THESIS: Hot forming and welding simulation of 9-12% CrP92 creep resistant steel The behaviour of three P92 steels with different chromium, molybdenum and tungsten contents, all within the ASME specification were studied. Welding simulations of the heat-affected zone (HAZ) regions focussed on the intercritical and fine-grained regions near the parent metal. Two constitutive models were successfully applied to analyse the flow stress and were used to predict the materials flow stress behaviour during deformation. Supervisors: Dr D Whitefield and Dr L Chown

OZONOH, Maxwell School of Chemical and Metallurgical Engineering THESIS: Co-gasification of coal and solid waste to Hydrogen enriched syngas in a fixed-bed gasifier In this study, blends of coal and solid waste were gasified to produce hydrogenenriched syngas. Tar from the co-gasification process was treated using biochar and nickel-biochar based catalysts. The performance efficiency of the gasifier was predicted employing Artificial Neural Networks, while the techno-economic analysis of the feedstock was carried out to evaluate profitability in the energy plant. Outcome of the study has been communicated to stakeholders and scientific community in the field via 5 journal articles and 3 peer-reviewed conference papers. Supervisor: Professor M Daramola RAMPAI, Tokoloho School of Chemical and Metallurgical Engineering THESIS: The investigation of the mechanical properties of MAX phase and cubic boron nitride ceramic composite made by spark plasma sintering The MAX phase alloys are unique carbide and nitride ternary ceramics materials. This work has proved that these materials can be manufactured using a combination of temperature and pressure lower than ever successfully attempted before. Their main advantages are that they are generally soft, machinable, heat-tolerant, strong and lightweight. These combined properties make these materials suitable for a wide array of applications. Supervisor: Dr D Whitefield VAN DER GRIJP, Yelena Michailovna School of Mining Engineering THESIS: Multi-point statistical simulation in modelling a structurally complex geological environment An innovative approach to geological modelling and stochastic estimation of a Mineral Resource in a structurally complex gold deposit is presented, using multiplepoint statistics. The developed framework contributes to the current trend towards machine learning in 3D geological modelling where minimal input from a geologist is required. It is confined to incorporating the existing structural understanding of the deposit and multivariate relationships into the model. Supervisors: Dr D Rose and Prof R Minnitt YEN, Yu-Chieh School of Electrical and Information Engineering THESIS: Demand modelling of horizontal electric water heaters Unlike most countries, the general practice in South Africa is to install an electric water heater, commonly known as a “geyser”, in a horizontal rather than a vertical orientation. The thesis makes an important contribution to understanding the impact this has, particularly with respect to demand-side management, power utility planning and load forecasting, where the cumulative effects of a large fleet of electric water heaters can be significant.

Doctor of Philosophy ADU-GYAMFI, Clement Chemical Pathology THESIS: Measurement on indoleamine 2, 3-dioxygenase activity, a potential biomarker for active tuberculosis disease in South Africa This thesis focused on improving the life of HIV-infected individuals through prompt and accurate Tuberculosis (TB) diagnosis. The study evaluated the activity of indoleamine 2,3-dioxygenase (IDO) as a blood-based biomarker for active TB disease. IDO is a key immuno-modulatory enzyme which directs host immunity towards Mycobacterium tuberculosis (MTB) tolerance. This work lays the foundations for development of a novel blood-based TB biomarker, urgently required for impacting the TB epidemic. Supervisors: Dr J George, Dr M Suchard and Dr D Savulescu AGOSTI, Yasmeen Mele Clinical Microbiology & Infectious Diseases THESIS: Measuring epidemiology and sero-correlates of protection against severe respiratory syncytial virus (RSV) associated hospitalisation in HIV exposed and unexposed South African children The candidate studied hospitalizations due to Respiratory Syncytial Virus (RSV) amongst Sowetan infants during their first year of life, including infants born to women living with HIV. She measured the incidence and clinical characteristics of RSV hospitalizations as well as the levels of protective RSV antibodies passed from mother to infant during pregnancy. Her hope is that these data will someday contribute to the development of RSV prevention measures such as a maternal RSV vaccine. Supervisors: Professor S Madhi, Dr E Simoes and Dr B Cai ANIM-BOAMAH, Oboshie Nursing Education THESIS: Development of a framework for assessing clinical competence of nursing students in Ghana: a multimethod study The paucity of clinical competency assessment research in Sub-Saharan Africa has led to assessment systems that are not context specific. There is a need for a contextspecific clinical competency assessment framework to guide clinical competency assessment in the sub-region. A multimethod study was conducted to develop a framework to guide and standardize the assessment of clinical competency of nursing students in Ghana. Supervisors: Dr C Christmals and Dr S Armstrong

AYENI, Oluwatosin Adetayo Paediatrics and Child Health THESIS: Multimorbidity and breast cancer in Sub-Saharan Africa: profile and impact on stage at diagnosis and breast cancer treatment decisions This research investigated the prevalence and pattern of multimorbidity in women with breast cancer, its determinants and impact on stage at diagnosis and cancer treatment decisions in Sub-Saharan Africa. The prevalence of multimorbidity among patients with breast cancer was high across different settings in SSA, mainly driven by socio-demographic factors, notably higher socio-economic status across different settings. Multimorbidity had a significant negative impact on first treatment received in those with early-stage disease. Supervisors: Dr M Joffe and Professor S Norris BACCI, Nicholas Anatomical Sciences THESIS: Reliability of forensic facial identification from CCTV recordings with implications for admissibility to court Facial identification is understudied in forensic practice. This actualistic study tested the best practice method for forensic facial comparison, namely morphological analysis. Analyses were conducted on the first large-scale, high-resolution, multimodal African face database of photographs and CCTV recordings developed for this project. The study validated the use of facial morphology in identification, via an extensive feature list, across different photographic, CCTV conditions and disguises, with medico-legal considerations. Supervisors: Dr N Briers and Professor M Steyn DLAMINI, Siphiwe Ndumiso Paediatrics and Child Health THESIS: Non-communicable disease risk in Black South Africans: dissecting the role of glucocorticoids In this project, epidemiology and genetic data were analysed to identify novel associations between glucocorticoids and cardio-metabolic risk factors in Black South Africans. We observed both glucocorticoid- and sex-specific associations. The findings support the hypothesis that glucocorticoids play a role in the development of the metabolic syndrome. Supervisors: Dr J Goedecke and Associate Professor Z Lombard EDGE, Amanda Psychiatry THESIS: How women come to commit neonaticide: a constructivist grounded theory of criminal cases Maternal neonaticide, the act of a mother taking the life of her new-born within its first 24 hours of life, is a complex human phenomenon. This is the first study in South Africa to investigate the conceptual and emotional processes as well as actions that underpin the women’s neonaticidal and non-neonaticidal pregnancies, among women who commit the act. A constructivist grounded theory is provided that reveals the underpinning pathways towards neonaticide which can be used to inform prevention and rehabilitation efforts.

GEARD, Amy Frances Haematology and Molecular Medicine THESIS: Gene therapy for visceral Gaucher disease Gaucher disease is a rare lysosomal storage disorder that presents with both neurological and visceral disease manifestations. This research developed a novel AAV vector that demonstrated potential to treat both forms of disease pathology in a murine model of this disease. This research also successfully created a new model of severe type 1 disease, which will facilitate investigation of novel therapeutics for Gaucher disease in the future. Supervisors: Professor P Arbuthnot, Professor S Waddington and Dr G Massaro HANRAHAN, Barbara Anne Nursing Education THESIS: A intervention programme to enhance respectful maternity care in labour by midwives in the public midwives’ obstetric units in a District in Gauteng Women are experiencing disrespect and abuse in facility-based childbirth in South Africa. Most women utilise the public sector maternity facilities, which include Midwives Obstetric Units - midwife-led primary health care facilities. A qualitative, multi-method design was applied. Postpartum women were interviewed about their childbirth experience. Midwives wrote naïve sketches and participated in nominal groups.

Supervisor: Dr S Armstrong HODSON, Bryan Physiology THESIS: Central Arterial Hemodynamics in the Normotensive Peripheral Blood Pressure Range This study provides an approach to identify individuals with normal blood pressure who are nevertheless at risk for blood pressure related cardiovascular events. It shows that even in individuals with normal blood pressure, aortic function changes with age and that these alterations in aortic function have a detrimental impact. The candidate’s data, published in several high impact international journals suggests that the assessment of aortic function may identify those individuals with normal blood pressure values that are most at risk for cardiovascular events. Supervisors: Professor A Woodiwiss and Professor G Norton HOOSEN, Yasar Pharmacy and Pharmacology THESIS: Antibody functionalized nanoliposomes to slow the progression of ovarian cancer This study focused on functionalized nanoliposomes to slow the progression of ovarian cancer. The nanosystem developed in the study successfully delivered two non-pharmacological molecules to reduce the virulent tumour-bearing burden and played a tumoricidal role by modulating the extracellular matrix formed from glycosaminoglycans overexpressed in ovarian cancer. The cationic nanoliposomal implant restricted the tumor growth, prolonged the survival times, and increased tumour inhibition rates with minimal off-target effects.

HOPKINS, Kathryn Lee Public Health THESIS: CURBING THE NON-COMMUNICABLE DISEASE EPIDEMIC: an evaluation of integrating rapid testing for NCD risk factors and navigated linkage to care into a standard HIV testing service platform for adults in Soweto, South Africa This study evaluated the quality and feasibility of, and patient satisfaction with integrating counsellor task-shifted rapid testing for non-communicable disease (NCD) risk factors (obesity, hypertension, hyperglycaemia and hypercholesterolemia) into a HIV testing services clinic for adults in Soweto, South Africa. Proportions of both passively referred and actively navigated patients linked to care and initiated on treatment were investigated, as were patient self-reported barriers to accessing care and treatment. Prevalence patterns of NCD risk factors were reported by sex, age, HIV status, antiretroviral therapy use, and previously diagnosed and/or controlled disease. Supervisors: Dr T Doherty and Professor G Gray KAGAHA, Alexander Public Health THESIS: Policy and practice of abortion care in Eastern Uganda This study investigated operations of power in policymaking and abortion-care practice, using critical ethnography. He shows tactics of manoeuvre health workers used to evade state surveillance and stay unnoticed in the health system. Privileged epistemic and normalised concepts, ordering of keynote addresses, and ruling relationships which efface abortion care from national agenda. His thesis theorises risk as emergent from care conducts, and reproductive materialism- conceiving and relating to women in the image of the economy undermines dignity and increases vulnerability.

Supervisors: Dr F Baiden, Associate Professor L Ibisomi and Professor T Chirwa MAUSER, Martin Ernst Surgery THESIS: The impact of penetrating abdominal trauma on gut-associated lymphoid tissue and the influence of HIV--infection. In this research project it is observed that trauma induces an immune cell-driven impairment of the intestinal epithelium, as well as an increased apoptosis of lymphocytes in the LP which is associated with a worse clinical outcome. With regards to HIV-seropositive patients we discovered that the compromised GALT in HIV-seropositive patients may predispose these patients to postoperative septic complications. Antiretroviral therapy does not result in an adequate immune reconstitution in this tissue. Hence, safe surgery and vigilant postoperative care with early, aggressive diagnostic investigations and a low threshold for relook operations is of paramount importance for these patients.

Being a relatively uncommon condition, this added to the profile of patients from other studies conducted in South Africa. In addition, human leukocyte antigen (HLA) Class I along with Class II antigens in sarcoidosis patients were evaluated. Serum immunoglobulin (Ig) G subclass levels in newly diagnosed cases with sarcoidosis 21

were assessed. The serum expression of approximately 800 microribonucleic acid (miRNA) in sarcoidosis patients were compared with race-, age- as well as gendermatched healthy controls. Analysis of serum chitotriosidase activity in sarcoidosis and tuberculosis (TB) patient cohort, both granulomatous diseases of differing aetiology, was undertaken and compared with controls. Supervisor: Professor C Feldman MOSALO, Annah Nursing Education THESIS: Development and pilot testing of a support intervention for women treated for cervical cancer The study utilised a mixed method approach to develop a support programme for women receiving curative treatment for cervical cancer at an Academic Hospital. The study was conducted in two phases. Phase 1 was an exploration of the support needs of women and the development of the programme whilst Phase 2 pilot-tested and evaluated the programme. The programme was effective in promoting women’s perception of being supported and they felt empowered in terms of knowledge about the disease and its treatment. They were confident that they would be able to tell others about their illness without being ashamed and encourage them to go for screening. Supervisor: Professor J Maree MOTAU, Tshegofatso Harold Physiology THESIS: Arteriosclerotic aortic dysfunction in groups of African ancestry in Africa This thesis advances our understanding of arteriosclerosis as a cause of arterial disease. He shows that in contrast to current dogma, arteriosclerosis is as strongly associated with arterial events over a younger as over an older adult age. However, these effects go undetected because the impact is on central arterial and not peripheral blood pressure. These results, published in several high impact international journals, highlight the need for intense blood pressure reduction in high-risk patients across the adult lifespan.

Supervisors: Professor A Stewart and Professor M Maleka NDLOVU, Nomagugu Physiology THESIS: Effects of dietary supplementation with Hibiscus sabdariffa calyces meal in broiler and egg laying quail (cotrnix coturnix japonica) Poultry farmers often incorporate synthetic growth promoters in the feed of birds. However, there are welfare concerns for the birds and the residues may negatively impact human health. Hibiscus sabdariffa calyces were investigated as a natural plant derived alternative in quail feed. Hibiscus reduced the fat content and increased the protein content of quail meat. In layers, Hibiscus reduced egg production. Therefore, Hibiscus is a viable natural feed additive to improve quail meat quality, but it is unsuitable for use in laying quail.

Supervisor: Associate Professor L Ibisomi POOPEDI, Machuene Ananias Paediatrics and Child Health THESIS: Factors influencing the vitamin D status of adolescents in Johannesburg, and its effects on body composition. The thesis focused on vitamin D status in children, its longitudinal tracking over a period of 10 years and association of 25(OH)D levels with body composition. Majority (74%) of children had “sufficient” vitamin D status, hence routine vitamin D supplementation was not warranted. No long-term association between values obtained in the early years of adolescence and those of the later years. 25(OH)D was significantly negatively associated with LDL-C, suggesting that vitamin D status might be associated positively with favourable lipid profiles in children and adolescents.

SOEPNEL, Larske Marit Paediatrics and Child Health THESIS: The development of children born to mothers with diabetes mellitus in pregnancy: growth, body composition, and cognitive and motor development The development of children born to mothers with diabetes mellitus in pregnancy: growth, body composition, and cognitive and motor development Hyperglycaemia in pregnancy is a growing global health concern. This thesis aimed to investigate its impact on childhood outcomes in urban South Africa. At birth, more severe hyperglycaemia, maternal BMI, and HIV-infection were associated with worse outcomes. At preschool age, the difference in adiposity between groups exposed and unexposed to maternal hyperglycaemia was largely explained by maternal BMI. Hyperglycaemia-exposed children showed poorer cognitive development. The impact of preconception and pregnancy on childhood health and development can guide future prevention efforts. Supervisors: Professor S Norris and Associate Professor K Klipstein-Grobusch STANLEY, Christopher Chikhosi Public Health THESIS: Joint modelling of recurrent clinical malaria episodes and longitudinal parasitemia data This study has shown that there is limited optimal analysis of data from recurrent malaria. Use of sub-optimal methods often lead to biased estimates of disease burden and misinterpretation of results. To address this, the study used novel recurrent event joint models which resulted in improved precision of estimates of recurrent malaria and increased power to detect disease risk. Simulation results from using such models showed the potential for designing clinical trials with relatively lower sample sizes. Supervisors: Professor Tobias Chirwa, Professor Lawrence Kazembe, Professor Miriam Laufer and Professor Mavuto Mukaka STREHLAU, Renate Paediatrics and Child Health THESIS: Neurodevelopmental intervention in Early-treated HIV-infected children HIV infection in the new-born can affect neurodevelopmental outcomes. This longitudinal follow-up study of birth-diagnosed children living with HIV (CLHIV) found that despite early diagnosis and treatment, CLHIV were still at risk of poor developmental outcomes that became more apparent with age. However, children who participated in the study’s home-based early childhood stimulation programme showed a trend towards higher scores on developmental assessment. The need for an early childhood developmental programme as part of a comprehensive health package for CLHIV was highlighted by this work.

Supervisor: Professor E Sideras-Haddad, Professor D Wamwangi and Professor A Forbes MUKONDA, Danny Mathematics THESIS: Bornological aspects of asymmetric structures The candidate studies bornologies and bourbaki-bounded sets on quasi-metric spaces. It turns out that if a set is Bourbaki-bounded on the symmetrized quasipseudometric space, then it is also Bourbaki-bounded in the quasi-pseudometric space, but the converse need not to be true. In addition, he shows that every realvalued semiLipschitz in the small function on a quasi-metric space is bounded if and only if the quasi-metric is Bourbaki-bounded. Consequently, he uses semi-Lipschitz functions to characterize those bornologies on asymmetric normed spaces that can be realized as bornologies of Bourbaki-bounded sets. Supervisor/s: Professor OO Otafudu and Dr WB Toko MUTANDA, Gideon Walter Geography, Archaeology and Environmental Studies THESIS: From livelihoods to citizenship: the redistributive land reform in Zimbabwe African land reforms have been contentious internationally and nationally due to the narrow view of their developmental role as the achievement of economistic and 42

livelihood outcomes. There is need to broaden evaluation of African land reforms beyond these outcomes since the new notion of development now embeds the citizenship concept.

THE PROCESSION Who are those? Which, Falalala? I see them coming Walking with swinging garments They are wearing head rings Where do they come from? Who are those? They are people with knowledge They are people in authority These are the ones What is that? It is a procession A procession of our heroes It is a procession A procession of our champions Here is a procession Of people of knowledge Here is a procession Of people of knowledge A procession A procession of our heroes

Ihele is known as the ‘Black’ Gaudeamus Igitur. In song, the writer, Mnomiya uses very poetic language to describe a graduation ceremony. The soloist sings of the ‘strange’ procession of people in long robes and head gear. The choir responds by saying that these people are academics who read profound books of knowledge. Mnomiya goes on to say that the graduates are an inspiration to all of us, and we will also graduate like them one day. The song goes on to wish the graduates well and it ends with a resounding “Halala” (well done!).

GAUDEAMUS Gaudeamus igitur Juvenes dum sumus Post jucundum juventutem Post molestam senectutem Nos habebit humus.

Let us rejoice therefore While we are young. After a pleasant youth After a troublesome old age The earth will have us.

Ubi sunt qui ante nos In mundo fuere? Vadite ad superos Transite in inferos Hos si vis videre.

Where are they Who were in the world before us? You may cross over to heaven You may go to hell If you wish to see them.

Vita nostra brevis est Brevi finietur. Venit mors velociter Rapit nos atrociter Nemini parcetur.

Our life is brief It will be finished shortly. Death comes quickly Atrociously, it snatches us away. No one is spared.

Vivat academia Vivant professores Vivat membrum quodlibet Vivat membra quaelibet Semper sint in flore.

THE UNIVERSITY MACE

Maces were originally weapons of defence, designed to break through armour. In medieval times, bishops carried a mace instead of a sword into battle to enable them to defend themselves in accordance with the canonical rule that forbade a priest to shed blood. In time, the mace has come to be regarded as a symbol of delegated authority vested in a person or an institution. At this University, it is a symbol of the authority vested in the Chancellor and a reminder of the mandate given by the legislature of this country to the University to grant degrees. The University mace is the work of the Edinburgh designer, silversmith and engraver, William Kirk, who designed and made the mace of the University of Stirling and of other institutions. It is silver-and gold-plated, is 1070 millimetres long and 180 millimetres broad and weighs seven kilograms. The heraldic devices used in the decoration reflect the character of this University as an institution of learning, set in a mining centre within the Republic of South Africa. The head of the mace with its spreading vertical blades is symbolic of the horns of a springbok. The central vertical spike is representative of a rock drill on the mine, and the amber stone set in the head is intended as a tribute to a past Chancellor through its association with his name, Bernstein, which in German means amber stone. The heavy quality of the head is consistent with the traditional concept of the mace as a weapon of defence. The collar repeats the shape of the head. It consists of eight cogs which symbolise the cog-wheel in the University coat of arms and represents mining and industry. The shaft is octagonal and divided into three sections. The coat of arms of the University is placed on the shaft under the collar. Below this the words Universitas Witwatersrandensis Johannesburgi: are inscribed, followed by the date in Roman numerals – MCMLXXVI (1977) – which signifies the year of the dedication of the mace. The mace is a symbolic portrayal of this University, this city, the Witwatersrand and the Republic of South Africa. It is a constant reminder to members of Council and Senate to uphold at all times the rights, powers and privileges of the University and its governing bodies. 51
