Prof Luzelle Naudé, Professor in the Department of Psychology, delivered her inaugural lecture on the topic: In Search of Self: Emerging Adults as Actors, Agents and Authors.

How do people endeavour to answer the question: Who am I?   This is the central question that Prof Luzelle Naudé – professor in the Department of Psychology at the University of the Free State (UFS), has built her academic career on. Under the title of her inaugural lecture, In Search of Self: Emerging Adults as Actors, Agents and Authors, delivered on14 September 2022, Prof Naudé traced the arc of her academic career over the past three decades. 

Development as a Scholar

Prof Naudé started by giving an overview of her research as an early scholar, investigating students’ learning experiences and predictors of student success, followed by an exploration of the adolescence stage within the context of South Africa. Prof Naudé’s research interest then led her to investigating the third decade of life: emerging adulthood. 

Interestingly, from the turn of the century, the group of 18- to 25-year-olds take longer to transition into adulthood. This group finds themselves in an in-between space, “not being an adolescent anymore, but definitely not being an adult either,” Prof Naudé explained. This has sparked an interesting scholarly debate: is emerging adulthood indeed a new developmental stage, or is it something only applicable to a minority of Western, affluent middle-class, university students? The answer is the former. There are actually many emerging adulthoods – also among our South African youth. 

Current Research Focus

Currently, Prof Naudé is interested in the narratives of emerging adults at the intersection of self and society. The self, she pointed out, unfolds through different layers, namely the actor, the agent, and the author. “Our South African emerging adults are acting in an increasingly complex and transitioning social world. As agents, they advance through this complexity by telling redemptive stories of generativity, upward mobility, and of liberation. And as authors, they reconstruct their past, present, and future into a coherent life story and a narrative identity,” Prof Naudé said.

The Way Forward

“I’ve became convinced,” Prof Naudé emphasised, “about South Africa and the Global South’s ability to contribute to global knowledge production.” Prof Naudé and her team are therefore adding a South African voice to several multicultural, multinational projects, including the African Long-Life Study – in collaboration with the University of Zurich – and the Selves within Selves project. Prof Naudé’s vision, however, is to ultimately establish an Identity Research Hub at the UFS to consolidate research activities in this field and to formalise interdisciplinary partnerships.

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.
