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.

Research eradicates bacteria from avocado facility

“The aim of my project was to identify and characterise the contamination problem in an avocado-processing facility and then to find a solution,” said Dr Amy Strydom, postdoctoral fellow in the Department of Microbial Biochemical and Food Biotechnology at the University of the Free State (UFS).

Her PhD, “Control of Listeria monocytogenes in an Avocado-processing Facility”, aimed to identify and characterise the contamination problem in a facility where avocados were processed into guacamole. Dr Strydom completed her MSc in food science in 2009 at Stellenbosch University and this was the catalyst for her starting her PhD in microbiology in 2012 at the UFS. The research was conducted over a period of four years and she graduated in 2016. The research project was funded by the National Research Foundation.

The opportunity to work closely with the food industry further motivated Dr Strydom to conduct her research. The research has made a significant contribution to a food producer (avocado facility) that will sell products that are not contaminated with any pathogens. The public will then buy food that is safe for human consumption.


What is Listeria monocytogenes?

Listeria monocytogenes is a food-borne pathogenic bacterium. When a food product is contaminated with L. monocytogenes, it will not be altered in ways that are obvious to the consumer, such as taste and smell. When ingested, however, it can cause a wide range of illnesses in people with impaired immune systems. “Risk groups include newborn babies, the elderly, and people suffering from diseases that weaken their immune systems,” Dr Strydom said. The processing adjustments based on her findings resulted in decreased numbers of Listeria in the facility.

The bacteria can also survive and grow at refrigeration temperatures, making them dangerous food pathogens, organisms which can cause illnesses [in humans]. Dr Strydom worked closely with the facility and developed an in-house monitoring system by means of which the facility could test their products and the processing environment. She also evaluated bacteriophages as a biological control agent in the processing facility. Bacteriophages are viruses that can only infect specific strains of bacteria. Despite bacteriophage products specifically intended for the use of controlling L. monocytogenes being commercially available in the food industry, Dr Strydom found that only 26% of the L. monocytogenes population in the facility was destroyed by the ListexP100TM product. “I concluded that the genetic diversity of the bacteria in the facility was too high and that the bacteriophages could not be used as a control measure. However, there is much we do not understand about bacteriophages, and with a few adjustments, we might be able to use them in the food industry.”

Microbiological and molecular characterisation of L. monocytogenes

The bacteria were isolated and purified using basic microbiological culturing. Characterisation was done based on specific genes present in the bacterial genome. “I amplified these genes with polymerase chain reaction (PCR), using various primers targeting these specific genes,” Dr Strydom said. Some amplification results were analysed with a subsequent restriction digestion where the genes were cut in specific areas with enzymes to create fragments. The lengths of these fragments can be used to differentiate between strains. “I also compared the whole genomes of some of the bacterial strains.” The bacteriophages were then isolated from waste water samples at the facility using the isolated bacterial strains. “However, I was not able to isolate a bacteriophage that could infect the bacteria in the facility.
