Two of the University of the Free State (UFS) SARChI Research Chairs have been included in the 2nd edition of Research.com ranking of the best scholars in the field of Social Sciences and Humanities.

Prof Melanie Walker from the UFS Higher Education and Human Development research group and SARChI Chair: Higher Education and Human Development, and Prof Ivan Turok, from the South African National Research Foundation, who hold the Research Chair in Strengthening Urban Economies: People, Place, Production and Policy, are ranked 41st (ranked 5 286 in the world) and 20th (2 825) in South Africa respectively.

According to the Research.com website, the best scientists ranking is a credible list of leading scientists from the field of Social Sciences and Humanities, established by means of a meticulous analysis of 166 880 scholars determined from multiple bibliometric data sources. For this discipline, as many as 15 317 researchers were analysed and their position in the ranking is based on a researcher’s D-index (Discipline H-index), which only includes papers and citation values for an examined discipline.

The success of a community

As a SARChI Chair in Strengthening Urban Economies: People, Place, Production, and Policy, Prof Turok explores how cities can drive economic growth and foster inclusive development in South Africa. His research analyses the factors contributing to the success of certain cities over others and identifies policies and practices that can enhance conditions for citizens and communities

He says this “pleasant surprise” (being ranked 20th in South Africa in the field of Social Sciences and Humanities) follows years of scientific work and writing.

“Research has also been a labour of love and rewarding in itself. It has fuelled my natural curiosity for learning more about the world, and I have had opportunities to visit places and meet people I would never have had otherwise,” says Prof Turok.

What it takes to be a researcher

Although one can learn the required skills and capabilities to be a good researcher, Prof Turok says having a natural yearning for knowledge and an intrinsic curiosity about the real world is helpful to have a long research career. “Careful mentoring and sound teachers are vital to become an effective researcher.”

He firmly believes research should be relevant to the society in which it is located – especially in a developing country like South Africa.

He continues by saying: “It should shed light on and help to understand the major problems and opportunities facing society, using the tools and techniques available to that particular discipline.” This honoured researcher says researchers should inform societies using simple terms and engage in discussions on matters it faces.

“Researchers should be outward-looking and interact constructively with policy-makers and practitioners to improve public policy while maintaining a healthy dose of scepticism about the intentions of the political elite and other powerful interests.”

When analysing the reasons behind varying levels of economic growth and inclusive development among cities, it is crucial to consider a diverse range of indicators. “Relying solely on a few narrow indicators can be misleading," says Prof Turok.

Indicators to take into consideration include: The economic productivity of the city (output per person) and the average income level, the level of employment in relation to the working-age population, which enables individuals to support themselves and their families financially, and the level of investment, which determines future growth, employment, and income levels.

The value of research

Prof Turok suggests that the government could play a significant role in strengthening urban economies and reducing inequalities by devolving more powers and resources to metropolitan municipalities as the effective coordination of housing and transportation investments is crucial for achieving economic growth and social inclusion in cities. He also recommends aligning the programmes and investment projects of provincial authorities and state-owned enterprises (SOEs) with those of the metropolitan areas.

“Currently, there is a disconnect between the activities of many SOEs and the interests of cities. For example, there is a considerable amount of vacant and underused land in well-located urban areas owned by SOEs, which they refuse to transfer to metros for housing purposes (highlighting the relevance of land reform in cities). Another example is the Sector Education and Training Authorities (SETAs), which operate in silos and do not align their training programmes with the needs of employers in cities,” explains Turok.

Being an internationally recognised expert in his field, Prof. Turok is regularly asked to advise esteemed organisations such as the United Nations and the African Development Bank. Prof. Turok, a former finalist for the National Science and Technology Forum (NSTF) Lifetime Achievement Award in 2021, will serve in this significant role until 2025.

Focusing on Education

Prof Walker, a distinguished scholar in the field of education sciences with an A1 rating from the National Research Foundation (NRF) – which funds SARChI – focuses on the profound impact of apartheid on education and civic life. She concentrates on (higher) education, primarily in the Global South, and addresses the intersecting research and practice challenges of decolonisation, methodology, inequalities, and justice.

This former professor of Higher Education at the University of Nottingham currently holds the esteemed position of UFS Distinguished Professor. She has supervised the production of 23 doctoral theses on higher education and human development since 2016. Additionally, she has delivered numerous keynote speeches worldwide and is an acclaimed author of books and journal articles within her area of expertise.

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.
