Symposium bridges the gap between students, staff, and management
Students from the UFS, UCLA and VUA shared on their collective experience within higher education at the colloquium.

The Unit for Institutional Change and Social Justice at the University of the Free State (UFS) united with the University of California, Los Angeles (UCLA), and the Vrije Universiteit Amsterdam (VUA) on the Bloemfontein Campus in a symposium discussing ‘Fragility and Resilience: Facets, Features and (Trans)Formations in Higher Education’. “It is really the only conference that brings together support staff, academic staff, students, and upper administration management, which includes vice-chancellors, rectors, presidents, and provosts,” said Dr Dionne van Reenen, Senior Researcher in the Unit for Institutional Change and Social Justice, and convener of the event.

Dr Van Reenen further explained that, when it comes to matters such as policy changes, contact between these various groups at a university is crucial. In general, upper management has very little contact with students. Students would rather approach academic staff. In turn, academic staff members are often reluctant to approach support staff, since support staff are already burdened with administrative tasks. But, Dr Van Reenen continued, all these stakeholders actually need to move closer to each other, since the Academic Project goal is the same: delivering excellent-quality graduates and producing new knowledge. With this in mind, the symposium programme specifically included panel presentations and discussions by academic as well as support staff and students. What emanated from these discussions was a rich variety of topics speaking to various aspects of fragility and resilience. The following are only a few excerpts from these engaging dialogues. 

Using counter-stories to narrate fragilities and resilience in higher education institutions in South Africa

Dr Fumane Khanare, Dr Ntombizandile Gcelu, and Pearl Larey – all three academic staff members in the UFS School of Education Studies, and Lihle Ndlovu, Head of Department for Business Studies at the uMfolozi TVET College – use narratives to interrogate fragility and resilience among black women in higher education. They wanted to go beyond surface conversations about how each was doing and decided to use critical race theory to question even their own stories through collaborative learning. They share, listen, question, and reflect, and as a result, create new narratives through counter-stories. “We are trying to explore our narratives,” Dr Khanare said, “not only as the outsiders, but as the insiders as well. From our background, we cannot ignore that we came here full of potential, but full of fragilities as well.” 

The ambiguity of change: The stories that South African student narratives tell 
Continuing the exploration of narratives, Dr Frans Kamsteeg from the Department of Sciences at VUA shared his research among students of the UFS who were part of the Leadership for Change programme. The programme, that came to an end in 2016, took UFS students through a process of leadership courses and training and included a trip to one of the external participating foreign universities. Dr Kamsteeg subsequently received several groups at the VUA and became interested in how these students engage in transformation processes at the UFS. Presenting seven vignettes of students’ narratives, Dr Kamsteeg revealed a tapestry of multivocality and fragility, and a meandering path of self-identity and transformation. “They learned a lot about academic citizenship and becoming responsible citizens,” Dr Kamsteeg added.

Keeping up with changing times: Student leaders, resilience, fragility, and professional development

Dr Marguerite Muller, Pulane Malefane, and Liezl Dick were all residence heads at the UFS. During the #FeesMustFall period, they realised that the role of student leaders had begun to change. They saw how these roles evolved and became interested in how student leaders became stakeholders and decision makers at the UFS. An interesting outcome from the arts-based research was that in the individual drawing exercise – in which students had to represent their lives as a winding river – fragility did not feature at all. Instead, the student leaders chose to depict sources of challenges and support, and how these factors built resilience. However, in the group exercise where students had to stage a puppet show, the stories revealed clear areas of fragility. Essentially, the students were willing to show fragility as long as they were fragile with others. “What we learned was that it is really important for student leaders to understand the complexity of their roles. Student leaders also need to learn and understand that it is okay to fail, that you need to grow and need to change, and that fragility in this sense is not necessarily a weakness,” Dr Muller concluded.

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.
