Dr Karen Venter
Dr Venter received her PhD at the December graduation ceremonies. She focused on addressing societal challenges through the practice of engaged scholarship in community-university research partnerships for the common good.

When asked what inspired her to pursue a PhD, Dr Karen Venter, Head of the Division of Service Learning in the Directorate Community Engagement at the University of the Free State (UFS), said she wanted to make a difference in addressing societal challenges through the practice of engaged scholarship in community-university research partnerships for the common good. 

“Also, I love to learn and share knowledge – and that is exactly what I did in this PhD, titled: An integrated service-learning praxis approach for flourishment of professional development in community-higher education partnerships.” 

She explains, “My five-articles-style thesis explored the contribution of an integrated service-learning praxis approach towards the flourishment of engaged scholarship in community-higher education partnerships. The approach combined community engaged service-learning (CESL), appreciative inquiry and appreciative leadership, to advance the praxis of engaged scholarship. The study was demarcated in the field of higher education, applied in the discipline of nursing education, and contextually bound to three interrelated action research cycles and settings – for international, national, and local level engagement.”

Community members participate in the research journey

“The intent of the study was to recognise the community-led action learning of community member participants at the core action learning set,” says Dr Venter. 

The study followed a participatory action learning and action research methodology. During her research journey, she was joined by members of the community, specifically from Bloemshelter – a shelter for the homeless. “They co-constructed and completed a four-year community-led action learning pathway to holistic development (spiritual, personal, professional), which brought about holistic social change and well-being in their livelihood, moving from dependence on others to establishing viable multiple micro-enterprises,” she says.

The UFS affiliated with GULL to reward the community member participants’ action learning. “Already in 2019, GULL certified their action learning with a Professional Bachelor’s degree, while I still had to document the action research, and only now received the PhD,” says Dr Venter. 

“I am grateful to all the participants who co-created action-oriented knowledge with me in the study, from international, to national, to local level of engagement.”

Integrating a PhD with work and life

A PhD requires a lot of hard work and effort, to the point that the lines between studies, work, and life become blurred. Dr Venter acknowledged that she tried to balance work/life and study, but “I was not very good at it”. 
Passion, patience, peace, perseverance, positivity, and prayer are good principles to maintain when you are in the process of completing a PhD. – Dr Karen Venter 

She elaborates, “Studying became an integrated part of my work and life.  For the duration of my studies, I started working at 03:00 and I also did not watch any television.” She did, however, make time for herself by joining the wellness workout programme presented by the UFS, enjoyed gardening, and playing with her grandchildren. “I also tried to rest one day over weekends, and made time to praise and worship, which energised me for the next week,” she adds. 

“Passion, patience, peace, perseverance, positivity, and prayer are good principles to maintain when you are in the process of completing a PhD, she believes. 

Dr Venter says that although writing a PhD is indeed lonely, it is also an exciting journey, “especially when you reach those moments of breakthrough that can only come to life after deep reflection.” She also describes it as a deep spiritual journey. “Almost like walking in and out of a labyrinth – and where many hours become equal to a breath.

She is very grateful to her supervisors, Dr Somarie Holtzhausen, Prof Mabel Erasmus, and Dr Elanie Myburgh. “I deeply honour and salute you for your unconditional and continuous coaching, compassion, and care – guiding, supporting, motivating, mentoring, and keeping me grounded until I completed the journey.”

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.
