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.

Mathematical methods used to detect and classify breast cancer masses

Examples of Acho’s breast mass
segmentation identification

Breast cancer is the leading cause of female mortality in developing countries. According to the World Health Organization (WHO), the low survival rates in developing countries are mainly due to the lack of early detection and adequate diagnosis programs.

Seeing the picture more clearly

Susan Acho from the University of the Free State’s Department of Medical Physics, breast cancer research focuses on using mathematical methods to delineate and classify breast masses. Advancements in medical research have led to remarkable progress in breast cancer detection, however, according to Acho, the methods of diagnosis currently available commercially, lack a detailed finesse in accurately identifying the boundaries of breast mass lesions.

Inspiration drawn from pioneer

Drawing inspiration from the Mammography Computer Aided Diagnosis Development and Implementation (CAADI) project, which was the brainchild Prof William Rae, Head of the department of Medical Physics, Acho’s MMedSc thesis titled ‘Segmentation and Quantitative Characterisation of Breast Masses Imaged using Digital Mammography’ investigates classical segmentation algorithms, texture features and classification of breast masses in mammography. It is a rare research topic in South Africa.

 Characterisation of breast masses, involves delineating and analysing the breast mass region on a mammogram in order to determine its shape, margin and texture composition. Computer-aided diagnosis (CAD) program detects the outline of the mass lesion, and uses this information together with its texture features to determine the clinical traits of the mass. CAD programs mark suspicious areas for second look or areas on a mammogram that the radiologist might have overlooked. It can act as an independent double reader of a mammogram in institutions where there is a shortage of trained mammogram readers. 

Light at the end of the tunnel

Breast cancer is one of the most common malignancies among females in South Africa. “The challenge is being able to apply these mathematical methods in the medical field to help find solutions to specific medical problems, and that’s what I hope my research will do,” she says.

By using mathematics, physics and digital imaging to understand breast masses on mammograms, her research bridges the gap between these fields to provide algorithms which are applicable in medical image interpretation.
