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.

Imagine that you have been diagnosed with bone cancer and only have six months to live. You are in a wheelchair because the pain in your legs is so immense that you can’t walk anymore – similar to a mechanism eating your bones from the inside.

You are lucky though, since you could be injected with a drug to control the pain so effective that you will be able to get out of the wheelchair within a day-and-a-half and be able to walk again. Real-life incidents like these provide intense job satisfaction to Prof André Roodt, Head of Inorganic Chemistry at the University of the Free State (UFS). The research, which is conducted by the Inorganic Group at the UFS, contributes greatly to the availability of pain therapy that does not involve drugs, but improves the quality of life for cancer patients.

The research conducted by the Inorganic Group under the leadership of Prof Roodt, plays a major role in the clever design of model medicines to better detect and treat cancer.

The Department of Chemistry is one of approximately 10 institutions worldwide that conducts research on chemical mechanisms to identify and control cancer. “The fact that we are able to cooperate with the Departments of Nuclear Medicine and Medical Physics at the UFS, the Animal Research Centre, and other collaborators in South Africa and abroad, but especially the methodology we utilise to conduct research (studying the chemical manner in which drugs are absorbed in cancer as well as the time involved), enhances the possibility of making a contribution to cancer research,” says Prof Roodt.

Technique to detect cancer spots on bone
According to the professor, there are various ways of detecting cancer in the body. Cancer can, inter alia, be identified by analysing blood, X-rays (external) or through an internal technique where the patient is injected with a radioactive isotope.

Prof Roodt explains: “The doctor suspects that the patient has bone cancer and injects the person with a drug consisting of an isotope (only emits X-rays and does no damage to tissue) that is connected to a phosphonate (similar to those used for osteoporosis). Once the drug is injected, the isotope (Technetium-99m) moves to the spot on the bone where the cancer is located. The gamma rays in the isotope illuminate the area and the doctor can see exactly where treatment should be applied. The Technetium-99m has the same intensity gamma rays as normal X-rays and therefore operates the same as an internal X-ray supply.” With this technique, the doctor can see where the cancer spots are within a few hours.

The same technique can be used to identify inactive parts of the brain in Alzheimer patients, as well as areas of the heart where there is no blood supply or where the heart muscle is dead.

Therapeutic irradiation of cancer
For the treatment of pain connected with cancer, the isotope Rhenium-186 is injected. Similar to the manner in which the Technetium-99m phosphonate compound is ingested into the body, the Rhenium-186 phosphonate travels to the cancer spots. Patients thus receive therapeutic irradiation – a technique known as palliative therapy, which is excellent for treating pain. A dosage of this therapy usually lasts for about two months.

The therapy is, however, patient specific. The dosages should correspond with the occurrence and size of cancer spots in the patient’s body. First, the location of the cancer will be determined by means of a technetium scan. After that, the size of the area where the cancer occurs has to be determined. The dosage for addressing total pain distribution will be calculated according to these results.

Technique to detect cancer spots on soft tissue
Another technique to detect cancer as spots on bone or in soft tissue and organs throughout the body is by utilising a different type of irradiation, a so-called PET isotope. The Fluor-18 isotope is currently used widely, and in Pretoria a machine called a cyclotron was produced by Dr Gerdus Kemp, who is a former PhD graduate from the Inorganic Research Group. The F-18 is then hidden within a glucose molecule and a patient will be injected with the drug after being tranquillised and after the metabolism has been lowered considerably. The glucose, which is the ‘food' that cancer needs to grow, will then travel directly to the cancer area and the specific area where the cancer is located will thus be traced and ‘illuminated’ by the Fluor-18, which emits its own 'X-rays'.

In the late 80s, Prof Roodt did his own postdoctoral study on this research in the US. He started collaborating with the Department of Nuclear Medicine at the UFS in the early 90s, when he initiated testing for this research.

Through their research of more than 15 years, the Inorganic Group in the Department of Chemistry has made a major contribution to cancer research. Research on mechanisms for the detection of cancer, by designing new clever chemical agents, and the chemical ways in which these agents are taken up in the body, especially contributes to the development in terms of cancer therapy and imaging, and has been used by a number of hospitals in South Africa.

The future holds great promise
Prof Roodt and his team are already working on a bilateral study between the UFS and Kenya. It involves the linking of radio isotopes, as mentioned above, to known natural products (such as rooibos tea), which possess anti-cancer qualities.
