Critical Dialogue
Guest speaker, Prof Gordon Zide, delivers his keynote address at the EDSA Critical Dialogue Series 2025.

The Office of the Executive Director: Student Affairs at the University of the Free State (UFS) hosted its annual Critical Dialogue Series on 29 April 2025 at the Centenary Complex on the Bloemfontein Campus. The dialogue brought together students, staff, and university leadership for an engaging conversation around ethical and servant leadership in higher education.

 

A conversation rooted in purpose

In his opening address, Temba Hlasho, Executive Director for Student Affairs said the dialogue was designed to provoke honest reflection and engagement on issues that affect student experience and institutional culture.

“We believe that there has to be some sort of transparency in terms of having to talk about topical issues that are very critical, that also touch on the very nerve of student experience,” Hlasho said.

He encouraged student leaders to see the platform not as ceremonial, but as a call to action. “You are in a country today where ethics have almost decayed. You, as the future of this country, will rely solely on the young people to change the narrative.”

 

Leadership anchored in service

UFS Vice-Chancellor and Principal Prof Hester C. Klopper delivered a powerful message on the importance of ethical and servant leadership in guiding the university’s direction. “Leadership – and specifically ethical and servant leadership – forms the cornerstone of what we stand for at the University of the Free State.”

She spoke about accountability, fairness, and leading with integrity. “It means treating every student fairly regardless of background or belief, and holding yourself accountable for your actions and decisions.”

Prof Klopper also highlighted the vital role student leaders play in shaping a culture of trust and excellence. “Leadership is not a title or a position, but a daily choice to serve with integrity, empathy, and purpose.”

 

Ubuntu, transformation, and power dynamics

The event’s keynote speaker was Prof Gordon Zide, an accomplished scholar, academic, intellectual, Africanist, author, transformation specialist, motivational speaker, and a former Vice-Chancellor and Principal of the Vaal University of Technology. Prof Zide is also a former Registrar at the University of South Africa. Drawing from a lifetime of experience in the sector, he interrogated the moral responsibilities of leadership within the South African higher education landscape.

“Leadership is a function of being a servant and being in charge of others,” he said. “It also requires the capacity to give strategic direction for the effective, efficient, and valued functioning of organisations.”

He emphasised that ethical leadership should be grounded in values such as vision, passion, patience, integrity, honesty, decisiveness, character, and charisma. Reflecting on the African philosophy of ubuntu, Prof Zide remarked: “When talking about servant leadership, it’s important to recognise other people and say to yourself: ‘I am what I am because of other people.’”

He encouraged students, particularly the current generation, to take charge and assume ethical leadership roles in their spaces. Referencing prominent anti-apartheid figure Robert Sobukwe, he urged, “Even when we are no longer here, they will always remember that we were there.”

Prof Zide also noted the practical benefits of ethical leadership in institutions, saying that it improves brand image, boosts morale among staff and students, and strengthens the recruitment process. He concluded by challenging the Department of Higher Education and Training (DHET), saying its tendency to micromanage universities undermines the autonomy and leadership authority of institutional management.

 

A call to lead with intention

Reflecting on the impact of the event, Acting President of the Institutional Student Representative Council (ISRC) Mpho Maloka said, “These kinds of conversations are needed because they help us go back to the ‘why’ – why we became student leaders in the first place, and how we can serve students in ways that actually make a difference.”

She added, “People have turned student leadership into something so political that others don’t even want to get involved. Dialogues like this bring it back to what really matters – serving students and growing as ethical leaders.”

As Prof Klopper concluded: “The lessons in ethical and servant leadership that you learn and practise here prepare you not just for impactful careers, but for responsible citizenship in a world desperately in need of ethical leadership.”

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
