The Economics and Management Sciences (EMS) Faculty at the University of the Free State (UFS) recently inaugurated its first Broadening Curricular Debate series, a concept conceived by the Dean of the Faculty, Prof Phillipe Burger. The inaugural debate, held on 22 November 2023 in the Equitas Senate Hall on the UFS Bloemfontein Campus, marked the beginning of a series designed to facilitate discussions among academics on crucial higher education matters.  Annari Muller, Chairperson of the Learning, Teaching and Digitisation Committee (LTDC), expressed the series’ purpose: “We organised this debate series to provide a platform for academics to discuss vital higher education matters. These sessions aim to stimulate critical conversations that empower UFS staff to enrich our curricula, enhance teaching practices, and shape broader educational strategies.’’ 

The motion presented to the house was, ‘The rapid integration of Artificial Intelligence in higher education perpetuates educational inequalities, widens the digital divide, and diminishes the value of personal instruction. The debate followed the structure of Intelligence Squared debates, with two teams comprising UFS staff from diverse departments, including the Department of Business Management, Department of English, Department of Public Management and the Department of Mathematical Statistics and Actuarial Science.

Naquita Fernandes, the Master of the House for the debate, emphasised the deliberate inclusion of members from diverse fields to infuse varied perspectives into the debate. “We believed that this diverse amalgamation of expertise would offer multifaceted insights, ensuring a holistic exploration of the subject matter. The debate structure was meticulously designed to encourage engaging discussions rather than formal academic presentations, allowing for a robust exchange of ideas.’’

The audience had the opportunity to vote on their stance before and after the debate, determining the winning team based on their ability to sway the audience with compelling arguments. The winning team, composed of Dr Hilary Bama (Senior Lecturer in the Department of Business Management), Dr Martin Rossouw (Senior Lecturer in Film and Visual Media), and Dr Rick De Villiers (Senior Lecturer in the English Department), successfully argued against the motion. 

The proposition team highlighted the existing gap between those with access to digital technologies and those without, advocating for a gradual and considered approach to AI integration in higher education. In contrast, the opposition team underscored the value of personal instruction in the face of AI, emphasising AI’s potential to provide constructive and effective feedback,  contribute to adaptive learning platforms, and accommodate unique learning styles and preferences. 

Following the debate, the audience was addressed by a team from Carnegie Math Pathways, providing insights into generative AI tools. Fernandes described the event as a proactive step in shaping the UFS academic landscape, moving away from reactive responses and exploring critical topics and strategies that could influence future policies and practices.

From wheat protein to perfect pizza

Barend Wentzel, an alumnus of the University of the Free State’s Department of Plant Sciences, is passionate about plant breeding. 

He literally eats and lives wheat proteins. In 1989 he initiated a breeding programme on arum lilies. “This breeding programme is at an advanced stage,” he said. Besides reading, playing the piano and accordion, Barend, due to the nature of his research at the Agricultural Research Council, also experiments with different types of ciabatta recipes made from sour dough. “I usually make my own pizza on Saturday evenings,” he said.

He is working at the Agricultural Research Council – Small Grain (ARC-SG) at the Wheat Quality Laboratory where he established a Cereal Chemistry Laboratory.

Complexity of flour quality

He explains that the focus of his research is on wheat protein composition. “The research conducted for my PhD study explains the complexity of flour quality to a certain extent, and it further emphasises the influence of the environment and genetic composition on selected baking characteristics. 

“Wheat protein can be divided into different types of protein fractions. These protein fractions contribute differently to dough properties and baking quality and the expression is affected by different components in the environment, including locality, rainfall and temperature. 

“Protein content alone does, however, not explain the variation in baking quality parameters, such as mixing time, dough strength and extensibility, and loaf volume.

“Several methods can be applied to quantify the different protein fractions. I am using high-performance liquid-chromatography (HPLC). The procedure entails the separation of a wheat protein extract through a column with chromatographic packing material. The injected sample is pumped through the column (known as the stationary phase) with a solvent (known as the mobile phase). The specific procedure, size-exclusion high-performance liquid-chromatography (SE-HPLC), is also used by the university’s Department of Plant Breeding, as well as in several international Cereal Chemistry Laboratories,” said Barend.

Dough strength and to loaf volume
“One of the highlights from the study was the positive contribution of the albumin and globulin protein fractions to dough strength and to loaf volume. The findings were wheat cultivar specific and the growing environment influenced the expression. The contribution of these protein fractions was much larger than previously reported for South African wheat cultivars,” said Barend. 
“Previous reports indicated that these protein fractions had a non-specific contribution to the gluten network during dough formation. The findings from this PhD justify further research on albumins and globulin proteins.” 

The Cereal Chemistry Laboratory at ARC-SG is involved in postgraduate student training under Barend’s guidance. He serves as co-promoter for several MSc and PhD students. He is also a collaborator on an international project with the International Maize and Wheat Improvement Centre (CIMMYT) in Mexico. Barend is furthermore working on improving wheat quality for processing and health purposes as a member of the expert working group of the International Wheat Initiative.
