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.

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.
