Prof Pearl Sithole
Prof Pearl Sithole says higher education needs to create space for Africa to be contributors and innovators of knowledge.

“Excellence is my main priority. For me, excellence means mastery of cross-communicable science and liberation of intellectual creativity that is free of mere complacency and acknowledging the right to analyse from where we stand. I am unapologetic about indigenous knowledge being the basis for scientific advancement.” This is how the newly appointed Vice-Principal: Academic and Research, Prof Pearl Sithole, sums up her vision and plan for academia and research on the Qwaqwa Campus. 

She believes that the human mind is geared towards ‘seeking and constantly explaining itself in the service of innovative change.’ 

“With this service of innovative change fully realised, the Qwaqwa Campus will be able to produce students who can analyse, innovate, and solve real social and world problems. For me, this is the University of the Free State graduate I pine to see – and there had better be truth to the ‘free’ part of this intellectual soul! I see Qwaqwa as a site for this intellectual innovation catalyst,” she said.

Social anthropologist

Prof Sithole is a Social Anthropology graduate with both master’s and PhD degrees from the University of Cambridge in England. “I stumbled upon Anthropology as part of my three majors at the then University of Durban-Westville. This discipline confessed its previous conceptual sins in a way that inspired change! From the exploration of human origins, to economic and political developments, and that was Anthropology. I was just absolutely taken by its acknowledgement of the intellectual project being socio-culturally rooted,” she said about her chosen area of study.

“I have always been inspired by Archie Mafeje’s work. I was motivated by Bernard Magubane’s scholarship, and I marvelled at the rigour of Oyeronke Oyewumi and Marilyn Strathern in feminist discourse. I mention these, because they inspire intellectual passion in me and I eventually met them,” she added.

Higher education in SA

She believes the higher-education sector is succumbing to streamlining methods, uninformed processes, and very little impact. “Like in government, higher education should not suffer from reduction of people into statistics, interventions into annual performance plan targets, and planning and monitoring into sanitised expenditure against targets. I see the shortage of relevance, responsiveness, and humanness; as well as ‘being captured’ by the latest fashions of doing rigid academe as the major challenges of higher education in South Africa today. We need to liberate our own innovative potential. We really need to create space for Africa to be contributors and innovators of knowledge,” Prof Sithole, the author of Unequal Peers, said.

She is, however, optimistic about the future of higher education in South Africa. “The day that we will have our innovation systems and systems of defining excellence – liberated from merely kneeling before the altar of Westernisation – we will gain integrity both conceptually and instrumentally in terms of responding to a society that is waiting for higher education to solve societal problems. The solution is to let those who see this truth continue to produce the knowledge despite being less than pleasing to the average scientific oversight bodies steeped in conventional Western validation.”

Research interests

Prof Sithole was previously employed with the Public Service Commission as a commissioner, a position she held from 2015 to August 2019. Prior to that, she worked at the University of KwaZulu-Natal as an Associate Professor of Community Development from 2010 to 2015, and at the South African Human Sciences Research Council (HSRC) as a senior researcher from 2006 to 2010. Her research interests and areas of expertise are governance, gender and development, analysis of social inequality, and the politics of knowledge production.

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.
