Bridging Knowledge Cultures
A group of academics from the University of the Free State (UFS) and the North-West University (NWU) contributed to a chapter in the book Bridging Knowledge Cultures in Rural Health Education, which was recently launched during an online event.

The Directorate of Community Engagement at the University of the Free State (UFS) celebrated the publication of a chapter in the book, Bridging Knowledge Cultures. This transformative book was edited by Walter Lepore, Budd Hall, and Rajesh Tandon, Unesco co-chairs of the Unesco Chair in Community Based Research and Social Responsibility in Higher Education.

Chapter 10 of the book – ‘Bridging Knowledge Cultures in Rural Health Education’ – was contributed by a group of academics from the UFS and the North-West University (NWU). The UFS contributors included Dr Karen Venter, Head of Service-Learning in the Directorate of Community Engagement; Alfi Moolman, former coordinator in the same department; and Dr René Walter Botha, Coordinator for Community Based Education and Rural Health in the Faculty of Health Sciences. From the NWU, the contributors included Prof Lesley Wood, Extraordinary Professor in Community-Based Educational Research; Beatrix (Bibi) Bouwman, Director for Sustainability and Community Impact; and Prof Hendri Coetzee, Extraordinary Associate Professor in the North-West University’s COMPRES research unit.

Identify knowledge differences/gaps

According to Dr Venter, the study conducted in the Xhariep District was considered a unique context for an in-depth exploration of participants’ subjective experiences to identify knowledge differences/gaps, and recommendations to bridge them. She states, “The aim of the initiative was to improve health outcomes by establishing lifestyle groups to enable the sharing of health information among participants and thereby encourage sustainable, accountable lifestyle practices.” 

Three questions derived from the case study were discussed during the launch: Who has the right to create knowledge? Who decides if knowledge is valid? And who will have access to the knowledge?

Other case studies included in the book also explored the dynamics of equitable research partnerships, providing practical recommendations to overcome obstacles and forge effective collaboration between academia and diverse communities.

Embrace the richness of diverse perspectives

Dr Venter believes that the launch event inspired the next generation of researchers and professionals to embrace the richness of diverse perspectives and knowledge cultures.

To access the rest of the case studies, including those from Indonesia, Malaysia, and India, you can download the book here. Access the discussion on YouTube here.

Parallel to the book, a guide was launched: Bridging Knowledge Cultures: A Guide for Community Practitioners and Community Organisations. You can access a copy here.

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.
