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.

NRF grants of millions for Kovsie professors

Two professors received research grants from the National Research Foundation (NRF). The money will be used for the purchase of equipment to add more value to their research and take the university further in specific research fields.

Prof Martin Ntwaeaborwa from the Department of Physics has received a R10 million award, following a successful application to the National Nanotechnology Equipment Programme (NNEP) of the NRF for a high-resolution field emission scanning electron microscope (SEM) with integrated cathodoluminescence (CL) and energy dispersive X-ray spectrometers (EDS).

Prof Bennie Viljoen from the Department of Microbial, Biochemical and Food Biotechnology has also been awarded R1,171 million, following a successful application to the Research Infrastructure Support Programme (RISP) for the purchase of a LECO CHN628 Series Elemental Analyser with a Sulphur add-on module.

Prof Ntwaeaborwa says the SEM-CL-EDS’ state-of-the art equipment combines three different techniques in one and it is capable of analysing a variety of materials ranging from bulk to individual nanoparticles. This combination is the first of its kind in Africa. This equipment is specifically designed for nanotechnology and can analyse particles as small as 5nm in diameter, a scale which the old tungsten SEM at the Centre of Microscopy cannot achieve.

The equipment will be used to simultaneously analyse the shapes and sizes of submicron particles, chemical composition and cathodoluminescence properties of materials. The SEM-CL-EDS is a multi-user facility and it will be used for multi- and interdisciplinary research involving physics, chemistry, materials science, life sciences and geological sciences. It will be housed at the Centre of Microscopy.
“I have no doubt that this equipment is going to give our university a great leap forward in research in the fields of electron microscopy and cathodoluminescence,” Prof Ntwaeaborwa said.

Prof Viljoen says the analyser is used to determine nitrogen, carbon/nitrogen, and carbon/hydrogen/nitrogen in organic matrices. The instrument utilises a combustion technique and provides a result within 4,5 minutes for all the elements being determined. In addition to the above, the machine also offers a sulphur add-on module which provides sulphur analysis for any element combination. The CHN 628 S module is specifically designed to determine the sulphur content in a wide variety of organic materials such as coal and fuel oils, as well as some inorganic materials such as soil, cement and limestone.

The necessity of environmental protection has stimulated the development of various methods, allowing the determination of different pollutants in the natural environment, including methods for determining inorganic nitrogen ions, carbon and sulphur. Many of the methods used so far have proven insufficiently sensitive, selective or inaccurate. The availability of the LECO analyser in a research programme on environmental pollution/ food security will facilitate accurate and rapid quantification of these elements. Ions in water, waste water, air, food products and other complex matrix samples have become a major problem and studies are showing that these pollutants are likely to cause severe declines in native plant communities and eventually food security.

“With the addition of the analyser, we will be able to identify these polluted areas, including air, water and land pollution, in an attempt to enhance food security,” Viljoen said. “Excess levels of nitrogen and phosphorous wreaking havoc on human health and food security, will be investigated.”
