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.

Dr Charlotte Boucher and Lindi Heyns examine possible anti-microbial activity in the skin of Western olive toad species
2014-12-22

 

Researchers Lindi Heyns and Dr Charlotte Boucher are working together on an interdisciplinary project between the Departments of Zoology and Entomology and Veterinary Biotechnology at the University of the Free State (UFS). The focus of their research is on the preliminary biochemical description of skin secretions in some South African toads.

The project forms part of an Honours study executed by Dwayne Pike under Heyns’ supervision. He is co-supervised by Dr Boucher who is assisting with the biochemical and microbiological assays.

Dr Boucher said, “Amphibians are characterised by the presence of cutaneous glands spread over the skin. There are two types of glands, namely mucous and granular (poison), located on the inner surface of the epidermis. Mucous glands are widely dispersed over the skin, while granular glands can be grouped and enlarged in specific regions. Mucous glands are generally associated with maintenance of humidity and cutaneous respiration, whereas granular glands function in chemical defence against predators and/or microbial infection. Studies indicate that the compounds produced by the granular glands belong to numerous chemical classes with diverse pharmacological activities.”

The products secreted by granular glands are rich in low molecular weight constituents of varied molecular types, including proteins, peptides and toxins. These secretions make the toad foul-tasting to predators and even toxic to other frog species. In addition, amphibians offer an attractive source of novel antimicrobials. Studies indicate that as a response to inhabiting microorganism-rich environments they synthesise and secrete a diverse array of antimicrobial peptides (AMPs) as an innate form of defence. Extensive research by various other research groups has been carried out on antimicrobial peptides of the genus Rana; however, hardly any studies have investigated the antimicrobial activity of African frog species.

The focus of this preliminary project is to determine the protein composition of the glandular secretions of the Western olive toad (Amietophrynus poweri), using biochemical tests, such as SDS-PAGE also known as protein gel electrophoresis combined with mass-spectrometry used to identify unknown peptides and proteins. This will give us an overview of the composition of the glandular secretions. Furthermore, we are also looking at microbiological tests, which include assays that test for possible anti-microbial activity against various bacterial and fungal species.
