The colloquium brought together students, staff and administration to work together on resolving ongoing problems within the higher education sector.

Where does resilience – or the lack thereof – in higher education come from? What does resilience and fragility even mean? These were some of the core issues examined during a recent symposium titled ‘Fragility and Resilience: Facets, Features and (Trans) Formations in Higher Education’. The Unit for Institutional Change and Social Justice hosted the event from 28 to 31 January 2020 on the University of the Free State (UFS) Bloemfontein Campus. The symposium – now in its seventh year – is a collaborative endeavour between the UFS, the University of California, Los Angeless (UCLA), and the Vrije Universiteit Amsterdam (VUA) to learn and share knowledge. “The real aim of the symposium is to address diversity and transformation issues from different contexts so that we can compare and contrast and learn best practices,” said Dr Dionne van Reenen, Senior Researcher in the Unit for Institutional Change and Social Justice, and convener of the event. 

Against the Psychologisation of Resilience

In a keynote address, Prof Michalinos Zembylas from the Open University of Cyprus argued against the potential psychologisation of resilience. According to Prof Zembylas, the concept of resilience is often framed as the psychological capacity of the individual to thrive through vulnerability and change. Such a view inevitably places the responsibility for success or failure on the shoulders of the individual and ignores the collusion between systems of oppression and structural inequalities. “The concept of resilience has become part and parcel of neoliberal governmentality – a growing emphasis on autonomous and reflexive individuals who have the capacity to conduct their own risk assessments and pursue their own life opportunities,” Prof Zembylas said. Therefore, within this neoliberalist ideology with its emphasis on the individual, people are led to believe that they need to continually adapt to threats that are essentially out of their control. A resilient person is, in other words, someone who permanently transforms themselves to accommodate the world without the possibility of actually changing that world. 

What impact does this have on higher education? Prof Zembylas noted that a neoliberalist perception of resilience discourages students “from imagining themselves as political agents who could collectively work to challenge harmful or unjust working and life practices”. Although universities use a great variety of tools and interventions to address students’ fragility, these approaches often focus on the vulnerability of the individual. Instead, Prof Zembylas proposed a shift towards an ontology that regards vulnerability as produced by conditions of oppression. A pedagogy of oppression is different from a pedagogy of vulnerability, since “instead of focusing on vulnerabilities, you would rather instil confidence in subjects to say no to abuse of power”.

The nature and role of student hope and meaning in goal setting and life satisfaction

Prof Itumeleng Khumalo, Associate Professor in the Department of Psychology at the UFS, delivered the following day’s keynote address. “Many studies concerned with youth have focused on their fears, worries and anxieties, instead of positive functioning and satisfaction with life,” Prof Khumalo remarked. In contrast, he opted to look at how hope and meaning shape students’ goals for higher education. Focusing on hope and meaning, however, does not deny the fact that South African students, in particular, are faced with substantial challenges. The majority of students enrolling in higher education in South Africa are first-generation entrants. Seventy percent of students do not have a graduate parent, and 45% do not have any family members who graduated. Most of these students are burdened with fears of failing, financial problems, difficulties with accommodation, worries about family members, inadequate knowledge regarding digital technology, and lack of support. 

Despite the above, a study by Prof Khumalo and Dr Angelina Wilson Fadiji showed that 85% of their student sample expected life would get better as a result of their education. The vast majority of students indicated that their main goal was to attain employment and build a career as a result of tertiary education. Students believe that getting an education will afford them opportunities to get ahead in life and enable them to become financially independent. “The perceived linear pathway from education to a better and successful life remains the dominant belief among these students, rendering education an undisputed panacea,” Prof Khumalo said. Ultimately, hope and meaning are sources of direction and motivation, and institutions of higher learning play a crucial role in human capacity development.

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.
