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.

Researcher part of project aimed at producing third-generation biofuels from microalgae in Germany

A researcher from the University of the Free State (UFS), Prof Johan Grobbelaar, was invited to join a group of scientists recently at the Institute for Bio- and Geo-Sciences of the Research Centre Jülich, in Germany, where microalgae are used for lipid (oil) production, and then converted to kerosene for the aviation industry.

The project is probably the first of its kind to address bio-fuel production from microalgae on such a large scale.  

“The potential of algae as a fuel source is undisputed, because it was these photoautotrophic micro-organisms that were fixing sunlight energy into lipids for millions of years, generating the petroleum reserves that modern human civilisation uses today.  However, these reserves are finite, so the challenge is marrying biology with technology to produce economically-competitive fuels without harming the environment and compromising our food security.  The fundamental ability that microalgae have to produce energy-rich biomass from CO2, nutrients, and sunlight through photosynthesis for biofuels, is commonly referred to as the Third-Generation Biofuels (3G),” said Prof Grobbelaar.

The key compounds used for bio-diesel and kerosene production are the lipids and, more particularly, the triacylglyserols commonly referred to as TAGs.  These lipids, once extracted, need to be trans-esterified for biodiesel, while a further “cracking” step is required to produce kerosene.  Microalgae can store energy as lipids and/or carbohydrates. However, for biofuels, microalgae with high TAG contents are required.  A number of such algae have been isolated, and lipid contents of up to 60% have been achieved.

According to Prof Grobbelaar, the challenge is large-scale, high-volume production, since it is easy to manipulate growth conditions in the laboratory for experimental purposes.  

The AUFWIND project (AUFWIND, a German term for up-current, or new impetus) in Germany consists of three different commercially-available photobioreactor types, which are being compared for lipid production.

The photobioreactors each occupies 500 m2 of land surface area, are situated next to one another, and can be monitored continuously.  The three systems are from Novagreen, IGV, and Phytolutions.  The Novagreen photobioreactor is housed in a glass house, and consist of interconnected vertical plastic tubes roughly 150 mm in diameter. The Phytolutions system is outdoors, and consists of curtains of vertical plastic tubes with a diameter of about 90 mm.  The most ambitious photobioreactor is from IGV, and consists of horizontally-layered nets housed in a plastic growth hall, where the algae are sprayed over the nets, and allowed to grow while dripping from one net to the next.

Prof Grobbelaar’s main task was to manipulate growth conditions in such a way that the microalgae converted their stored energy into lipids, and to establish protocols to run the various photobioreactors. This was accomplished in just over two months of intensive experimentation, and included modifications to the designs of the photobioreactors, the microalgal strain selection, and the replacement of the nutrient broth with a so-called balanced one.

Prof Grobbelaar has no illusions regarding the economic feasibility of the project.  However, with continued research, optimisation, and utilisation of waste resources, it is highly likely that the first long-haul flights using microalgal-derived kerosene will be possible in the not-too-distant future.

Prof Grobbelaar from the Department of Plant Sciences, although partly retired, still serves on the editorial boards of several journals. He is also involved with the examining of PhDs, many of them from abroad.  In addition, he assisted the Technology Innovation Agency of South Africa in the formulation of an algae-biotechnology and training centre.  “The chances are good that such a centre will be established in Upington, in the Northern Cape,” Prof Grobbelaar said.
