GRADUATION CEREMONY
A MESSAGE TO GRADUATES FROM THE CHANCELLOR
A hearty congratulations to the class of 2025! Your hard work and persistence have paid off, showing your character and grit.
The past year changed the world as we know it, with no less than 60 countries and more than 1.3 billion people globally going to vote, including our own country. The outcomes have changed geopolitics, with the Global North becoming more internally focused. The resurgence of economic protectionism has altered trade landscapes, causing ripples across global markets. The rise of artificial intelligence and big data further reshapes the balance of power, as nations compete for supremacy in these fields. Climate change, a universal threat, has become a catalyst for geopolitical tension. The race for control over natural resources, especially in the Arctic and other vulnerable regions, has intensified. South Africa has not been spared in the regional conflict, losing our own young fighters for peace in the DRC. Amid all the challenges that are unfolding, countries must come together to address environmental issues, choosing peace over wars, collaboration over conflict. You have conquered the academic journey, use your knowledge and your power to build bridges rather than walls. Be the visionary inclusive leaders who serve for greater good. The world needs that more than ever!
Your hard work to reach the pinnacle of your academic achievement, under immense challenges, is a true reflection of your resilience and commitment. It is this resilience that makes us confident that you have what it takes to build a better future that is equal and just. History has proven time and again that it is the weakest amongst us that determine our strength as a nation. The highly educated have the responsibility to enlighten and fight for social justice for the marginalised, for the good of humankind.
As the twentieth meeting of the Group of 20 heads to our shores, a first for the continent of Africa, we have chosen Solidarity, Equality and Sustainability as our G20 theme. This speaks to our recognition of the interconnected of nations. Our shared future depends on mutual understanding, cooperation, equality and stability across nations. As our future leaders you need to adapt to an uncertain world, embrace diversity, and foster dialogue. That will help you to craft a healthier, more balanced world for future generations.
As you venture into the world, take time to expand the depth and breadth of your knowledge. Read outside your specialisation, engage with people outside your comfort zone. Understand the plight of people less fortunate than yourself. Be the change you want to see in your country first then the world. Leaders who leave footprints worth emulating, are not only the brightest but also those who take time to learn from others, who are accountable for their actions and omissions, who use what they know and what they have, to make the world a better place. Leaders who care. Those leaders do this consistently with Humility and Integrity, Always. May you be those leaders! HALALA!

Gaudeamus igitur
Juvenes dum sumus
GAUDEAMUS
Post jucundum juventutem
Post molestam senectutem
Nos habebit humus.
Ubi sunt qui ante nos
In mundo fuere?

Atque irrisores.
Let us rejoice therefore
While we are young.
After a pleasant youth
After a troublesome old age
The earth will have us.
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.
Our life is brief
It will be finished shortly.
Death comes quickly Atrociously, it snatches us away. No one is spared.
Long live the academy!
Long live the teachers!
Long live each male student!
Long live each female student!
May they always flourish!
Long live all maidens
Easy and beautiful!
Long live mature women also,
Tender and loveable
And full of good labor.

And the One who rules it!
Long live our City
And the charity of benefactors
Which protects us here!
Let sadness perish!
Let haters perish!
Let the devil perish!
Let whoever is against our school
Who laughs at it, perish!

Ms Kgomotso Mufamadi President of Convocation Wits University

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!).
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.
ACADEMIC DRESS
The academic dress of this University is patterned on that of the Universities of Oxford and Cambridge, with modifications based on the model of the University of London and certain individual features, particularly in the costumes of office bearers and the hoods of degreesof bachelor and master.
Dress for Office Bearers
•The Chancellor wears a scarlet silk gown with a broad facing of black velvet down each side, embroidered in gold and a black velvet cap with gold cord and tassels.
•The Vice-Chancellor and Principal wears a blue silk gown with a broad facing of gold silk down each side, embroidered in blue, the sleeves being lined with gold silk. The cap is of the same design as that of the Chancellor.

•The academic dress of the Deputy Vice-Chancellors and the Executive Directors is the same as that of the Vice-Chancellor and Principal, except that the colour of the facing and sleeves of the gown and of the cord and tassels of the cap is silver-grey.
•The gown of the President of Convocation is of blue silk, with a broad facing of gold silk down each side, the sleeves being lined with white silk. The cap is the same as that of the Chancellor, but with a blue cord and tassels.
•The Registrar wears a black silk gown with a broad facing of blue silk down each side, bordered with gold braid. The cap is the same as that of the President of Convocation.
•A member of Council wears a black silk gown with a broad facing of gold silk. The cap is the same as that of the Chancellor.
•The gown of the President of the Students’ Representative Council is black with a broad facing of blue satin.
Graduands’ Gowns
•The gowns for all degrees of bachelor and master of the University are black, of the same pattern as the gown for a Master of Arts at the University of Oxford.
•The gown for the degree of Doctor of Philosophy is scarlet, after the University of London pattern.
•The gown for a senior doctorate is the same as that for the PhD, but with a gold satin facing on each side of the gown and with the sleeve button and cord in gold.
The Academic Hood
The academic hood is the principal feature of the costume for holders of our degrees of bachelor and master. The hood for the PhD is standard, regardless of the Faculty in which the degree was obtained. It is scarlet silk, lined with white silk.
Degree Colours
The hoods reflect the colour or colours of a particular degree or associated degrees.
DISTINCTLY WITS
As a public University in South Africa that is over a 100 years old, Wits is proud of its record of achievement as a significant contributor to our society. We contribute capable people to society that are training in their chosen field that are engaged and able to tackle problems using evidence-based solutions. We also engage with our communities to share knowledge that we create so as to make a positive impact on the quality of life. Wits for Good.
Wits is a world-class research-intensive university based on our intellectual excellence, international competitiveness, and commitment to social justice; all of which have a measurable impact.
What makes Wits distinct?
Here are a few of many differentiators:
•An international perspective that helps us maintain high standards in teaching and learning and research, while not distracting us from our place in Johannesburg, South Africa, and Africa. In 2024 Wits authors published articles with co-authors from 199 universities, 94% of which were from countries other than South Africa.
•An intellectual hub of Africa, a founding member of the African Research University Alliance.
•An active and engaged community leader that takes a stand on social issues and is fully committed to the advancement of the public good.
•A growing contribution to the body of knowledge through peer reviewed academic publications: 4563 in 2024 and an average growth rate of 4% per year over the last five years.
• Knowledge contribution that is above global quality averages in several fields including: clinical and pre-clinical health studies (76% above global norms); arts and humanities (58% above global norms); life sciences (36% above global norms); physical sciences (12% above global norms).
• Wits is particularly associated with the study of the fields of virology, particle physics and the Higgs Boson, malaria, archaeology, paleontology, paleoanthropology, violence, local and regional politics, geochemistry, rock mechanics, deep mining, forensic anthropology, climate change, migration, social justice, and many more.
• Proud of the four Nobel laureates and the 99 Rhodes Scholars.
• Proud of our current 42000 students of whom 16600 (40%) are undertaking postgraduate studies and learning to make their own unique contributions to the global knowledge base.
• Proud of our more than 200 000 graduates. More than 90% of Wits graduates obtain permanent employment within 12 months of graduation.
• Proud of its ability to raise external funding to support and drive its research efforts, with contributions exceeding R 2 billion per annum.

THESIS: Using organisational culture to derive performance improvement model for Tshwane Metropolitan Municipality
The study explores the role of organisational culture in enhancing performance within South African municipalities, focusing on Tshwane Metropolitan Municipality. While several studies have interrogated poor municipal performance in South African Municipalities, they lack criticality because they do not utilise comparative approaches. Using grounded theory, this research fills this void by empirically and critically exposing the dimensions of poor municipal performance before going on to propose how we can enhance service delivery at subnational level.

CAPAZARIO, Michele Economics
THESIS: A structuralist analysis of income distribution and its influence on the macroeconomy
The research aims to propose a novel set of theoretical models using the Structuralist approach to evaluate the relationship between functional income distribution and macro aggregates. The research tests these relationships using econometric techniques for 7 countries. We find that shifts in income distribution from some GDP maximising level has non-negligible effects on macroeconomic aggregates like inflation, household debt, exchange rates, and central bank policy.

CHIROWODZA, Joe Josiah Economics
THESIS: Essays in forensic economics: exploring issues of lost earnings from personal injury and wrongful death in South Africa
The candidate’s groundbreaking research develops innovative methodologies for estimating compensation to potential victims of personal injury and wrongful death in South Africa. Through rigorous analysis of work-life expectancies, personal consumption rates, and educational outcomes using National Income Dynamics Survey data, the research reveals significant disparities across gender, race, and employment sectors. The findings highlight critical needs for improved forensic economic assessments in legal cases and policy interventions to address systemic inequalities in South Africa’s labour market and judicial compensation system.

THESIS: Competition and strategy in private higher education in Ghana: managing complexity and uncertainty
The study examined the competition and strategy within the private higher education sector in Ghana, focusing on stakeholders’ choice factors for selecting private higher education institutions (PHEIs), as well as the challenges faced by managers of PHEIs and how these challenges manifest themselves within the context of competition, strategy and regulation. The study reveals that navigating the duality of conformity and strategic positioning of the PHEIs bring in its wake complexities in the institutions’ operations, governance and strategic direction.

HUNGWE, Brian Law
THESIS from the: The implications of the internet and technology on South Africa’s copyright holders’ remuneration: Lessons European Union and Ghana
It identifies that the digital technology’s seamless content copying, and dissemination capabilities deprives South Africa’s copyright holders’ remuneration rights. The situation is compounded by a copyright law regime that has not sufficiently adapted to the Digital Age and carries private copying exceptions without providing for authors’ statutory remuneration compensation framework. Guided by a utilitarianism theoretical approach, the thesis therefore proposes a private copying levy to create new revenue stream for copyright holders to foster innovation and avoid market disequilibrium.
Supervisor: Professor M Forere
JOLLIFFE, Mark Derrick Law
THESIS: The regulation of executive remuneration (including incentive-linked performance measures) in light of the socioeconomic concerns prevalent in South Africa
This interdisciplinary thesis begins with recent amendments to the South African Companies Act requiring remuneration disparity disclosures and suggesting an openness to addressing South Africa’s socioeconomic problems through company law. The persuasive and well-supported argument draws in a wide range of resources from various jurisdictions and disciplines (notably law, finance and management) to develop an innovative and pioneering reform agenda. These reforms would require executive remuneration to specifically incorporate more relevant and likely to be effective financial and social incentive-linked performance measures to enhance corporate sustainability and improve responsiveness to the interests of all definitive stakeholders.
Supervisor: Professor J Klaaren
LEBITSE, Palesa Law
THESIS: Decision making and case attrition in rape cases: a feminist jurisprudence perspective
This study is an empirical study of prosecutorial attrition in rape cases. The study uses mixed methods (quantitative and qualitative) to examine data derived from Umlazi Police Station in KwaZulu Natal. This thesis is approached from a feminist jurisprudence perspective to analyse legal texts that critically identify gender inequalities. Feminist critical theorists predict that external factors in the legal system that go beyond the actual legal burden influence the outcome of cases.
Supervisor: Professor T Madlingozi
MAKAE, Itumeleng Godfrey Management (WBS)
THESIS: Corporate governance and the developmental role of South African stateowned enterprises: the case of Transnet
This study is awarded to Itumeleng Makae for his innovative study of corporate governance and the developmental role of State-Owned Enterprises (SOEs) in Southern Africa. The thesis provides a deep examination of Transnet Freight Rail’s role in advancing regional integration through cross-border infrastructure projects, highlighting the interplay between governance models and operational performance. By proposing a stakeholder-oriented framework rooted in PanAfricanism and the principles of Ubuntu, Makae’s work challenges conventional governance paradigms and offers a transformative approach for SOEs in fostering economic resilience and regional cooperation.

MAKUMBE, Happiness Economics
THESIS: Energy and Commodity Price Volatility in Sub-Saharan Africa: The Role of Uncertainty
The candidate holds both a Master of Science and a Bachelor of Science (Honours) in Economics from the University of Zimbabwe. Her thesis examines the link between energy prices, agricultural commodity markets, and policy uncertainties in sub-Saharan Africa. It reveals how oil price shocks and global uncertainty impact food security, geopolitical risk influences energy and agricultural spillovers, and climate risk influences dynamic spillovers. The study emphasizes a holistic policy approach for sustainable agriculture.
Supervisors: Professor I Fasanya and Professor J Dikgang
MASARAURE, Robson Management
THESIS: Leadership for employee engagement in a global organisation
(WBS)
This thesis examines the link between agile, adaptive and multiplier leadership styles, and employee engagement in a global organisation with the moderating role of existential thinking. The study improves the Twenty-Sixty-Twenty (TST) theory to better align with the current business environment and proposes a framework suitable for employee engagement incorporating existential philosophy. Findings advance theory and practice, identifying the contemporary leadership approaches that are effective in global organisations.
Supervisor: Dr M Matshabaphala
MATUBATUBA, Relebohiseng Marketing
THESIS: Why do they stay? Drivers of blood donor loyalty: a relationship and social marketing perspective
This study examined the drivers of blood donor loyalty through a relationship and social marketing lens, integrating sociopsychological constructs (e.g., guilt, pride, habit) and relationship marketing principles (e.g., satisfaction, service quality). Findings suggest that attitudinal loyalty is the strongest predictor of repeat donation, while factors like facilitating conditions and social influence significantly shape donor behaviour. The study provides a theoretical framework blending behavioural theories with empirical insights, alongside practical strategies for blood donation organisations to enhance retention. By employing a mixedmethods approach, it offers evidence-based solutions to address global blood shortages, advancing both social marketing scholarship and donor engagement practices.
Supervisors: Professor P Issock Issock and Dr V Zulu
MUFANDAEDZA, Dhibhora Economics
THESIS: The political economy of political regimes and trade flows: a case of Zimbabwe 2005-2020
The candidate’s thesis undertakes a rigorous examination of Zimbabwe’s trade and political regimes between 2005 and 2020. It explicates the intricate interplay between political dynamics and economic outcomes, elucidating how political instability precipitated by the ruling ZANU-PF had profoundly adverse effects on the economy. This instability manifested in severe balance of payments issues and widespread socioeconomic hardships for the Zimbabwean populace. The thesis attributes these deleterious economic and social challenges to the political and economic decisions enacted by the ruling ZANU-PF.
Supervisor: Dr L Mondi
NASILA, Jason Biketi Management (WBS)
THESIS: Effects of Africa’s colonial and slave trade history on the nexus of education and economic development
The study examines the “Effects of Africa’s Colonial and Slave Trade History on the Nexus of Education and Economic Development”. Precolonial and colonial educational development explain the significant impact of intergenerational mobility on contemporary economic development. Educational development is connected to deep evolutionary traits, slavery intensity, and types and policies of colonisation. Yet, there is a contemporary disconnect between educational development and economic development, which is attributable to neocolonialism and neoliberalism, as well as to high slavery and slave trade.
Supervisors: Professor O Kodongo and Professor K Ojah
NDLOVU, Elona Nobukhosi Management (WBS)
THESIS: Developing a South African business coaching framework for entrepreneurs in business incubators
Considering relatively little is known about the approaches and methodologies of entrepreneurial coaching, the thesis formulated a South African entrepreneurial coaching framework to improve outcomes for entrepreneurs in terms of growth and sustainable businesses. Using a mixed-method, cross-sectional design within a pragmatic paradigm the findings indicate that demographics and cultural intelligence are critical success factors. Overall, a systems approach is advocated encompassing the entrepreneurial ecosystem in which incubators operate collectively with the community, coaches, technical trainers, and the entrepreneurs.

NXUMALO, Ntombifuthi Dorah Law
THESIS: COAL MINE CLOSURES IN SOUTH AFRICA - Does the current policy and regulatory framework promote sustainable mining?
The thesis reframes South African policy and regulatory framework on coal mine closure through the lens of sustainable mining. The study employed a qualitative research method encompassing critical analysis of desktop sources alongside empirical data gathered from interviews and observation of an active mine closure at Exarro’s Tshikondeni coal mine. The study underscores the need for inclusive, integrated mine closure planning conducted within the parameters of a national strategic land use plan and a balanced, clear, and simplified regulatory framework.

THESIS: Essays on online investor sentiment
This thesis compares social media and news media sentiment, examining their influence on stock markets in the USA, UK, South Africa and Brazil. It highlights that sentiment effects vary across markets, reflecting differences in contagion, impact, and information flow. Crucially, the findings show that the two are interconnected rather than independent proxies of investor sentiment. Their interplay shapes market behaviour, influencing stock market outcomes. Understanding this relationship is essential for accurately capturing investor sentiment and its broader financial implications.

SCHWALBACH, Joao Bruno Business Finance
THESIS: Enhancing Global Equity Returns with Trend-Following and Tail Risk Hedging Overlays
This thesis shows that overlaying trend-following and tail hedging on a global equity portfolio adds convexity and improves absolute and risk-adjusted returns. Tail hedges mitigate sudden crashes, whereas trend-following supports equities in protracted bear markets. Using a portable alpha framework, the strategy preserves full equity beta exposure and employs the overlays as sources of alpha, generating a statistically significant monthly excess return after controlling for conventional risk factors. The research outcomes are reported clearly and fully and the conclusions from the research are well-justified and integrated into the larger body of international knowledge. It is likely to have a substantial impact on the Finance discipline.

THESIS: The potential protective effects of stearic acid against diet-induced metabolic syndrome in growing fructose-fed sprague-dawley rats
Although saturated fats and fructose are commonly added to food, they have been associated with poor metabolic health. Recent studies have shown that some saturated fats can have positive health benefits. This study investigated the impact of a diet enriched with the saturated fat, stearic acid and highfructose on general health, liver fat deposition and kidney health of rats. Stearic acid prevented high-fructose diet induced metabolic disorders and thus should be considered when saturated fat is required in the preparation of foods high in fructose.

THESIS: Perpetuating Tribalism in Community Radio Coverage: The Case of Malamulele FM and Vuwani FM in Limpopo Province, South Africa
This research examined the role of community radio in post-apartheid South Africa, using Limpopo’s Malamulele FM and Vuwani FM as case studies. In `democratic’ South Africa community radio was given the mandate to unite cohabiting disparate ethnic groups within previously racially homogenized spaces by promoting multilingualism and social cohesion. The study thus interrogates how language functions ideologically in community radio broadcasting to privilege dominant ethnic groups and perpetuate tribalism. It fundamentally recommends the realignment of community broadcasting language policy to foster social cohesion, reflecting a multilingual and inclusive South African society by ensuring equal representation of tribes instead of majoritarianism in programming.

THESIS: Citizenship education and learners with mild-intellectual disabilities in South Africa: a critique of post-apartheid citizenship education policy
On a global and regional scale, citizenship education reflects three features, i.e., legal status, feeling of belonging and active participation. The central target of her critique is the state liberal policy’s approach to educating learners with mildintellectual disabilities in post-1994 South African schools. Using post-apartheid citizenship education policy as a focal point, the candidate argues that effective citizenship education for learners with mild-intellectual disabilities is an ongoing struggle that is rooted in communitarianism (group solidarity) strengthened by civic-republicanism (duties and responsibilities).
