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.

To tan or not to tan: a burning issue
2009-12-08

 Prof. Werner Sinclair

“Some evidence exists which implies that sunscreens could indeed be responsible for the dramatic rise in the incidence of melanoma over the past three decades, the period during which the use of sunscreens became very popular,” says Prof. Werner Sinclair, Head of the Department of Dermatology at the University of the Free State. His inaugural lecture was on the topic Sunscreens – Curse or Blessing?

Prof. Sinclair says the use of sunscreen preparations is widely advocated as a measure to prevent acute sunburn, chronic sun damage and resultant premature skin aging as well as skin malignancies, including malignant melanoma. There is inconclusive evidence to prove that these preparations do indeed achieve all of these claims. The question is whether these preparations are doing more harm than good?

He says the incidence of skin cancer is rising dramatically and these tumours are induced mostly by the ultra-violet rays.

Of the UV light that reaches the earth 90-95% belongs to the UVA fraction. UVC is normally filtered out by the ozone layer. UVB leads to sunburn while UVA leads to pigmentation (tanning). Because frequent sunburn was often associated with skin cancer, UVB was assumed, naively, to be the culprit, he says.

Exposure to sunlight induces a sense of well-being, increases the libido, reduces appetite and induces the synthesis of large amounts of vitamin D, an essential nutritional factor. The use of sunscreen creams reduces vitamin D levels and low levels of vitamin D have been associated with breast and colon cancer. Prof. Sinclair says the 17% increase in breast cancer from 1981 to 1991 parallels the vigorous use of sunscreens over the same period.

Among the risk factors for the development of tumours are a family history, tendency to freckle, more than three episodes of severe sunburn during childhood, and the use of artificial UV light tanning booths. He says it remains a question whether to tan or not. It was earlier believed that the main carcinogenic rays were UVB and that UVA merely induced a tan. The increase in UVA exposure could have severe consequences.

Prof. Sinclair says the UV light used in artificial tanning booths consists mainly of pure UVA which are highly dangerous rays. It has been estimated that six per cent of all melanoma deaths in the UK can be directly attributed to the use of artificial tanning lights. The use of an artificial tanning booth will double the melanoma risk of a person. “UVA is solely responsible for solar skin aging and it is ironical that tanning addicts, who want to look beautiful, are inflicting accelerated ageing in the process,” he says.

On the use of sunscreens he says it can prevent painful sunburn, but UVA-induced damage continues unnoticed. UVB blockers decrease vitamin D synthesis, which is a particular problem in the elderly. It also prevents the sunburn warning and therefore increases the UVA dosage that an individual receives. It creates a false sense of security which is the biggest problem associated with sunscreens.

Evidence obtained from the state of Queensland in Australia, where the heaviest and longest use of sunscreens occurred, boasted the highest incidence of melanoma in the world. A huge study in Norway has shown a 350% increase in melanoma for men and 440% for women. This paralleled the increase in the use of UVB blocking sunscreens while there was no change in the ozone layer. It did however, occur during that time when tanning became fashionable in Norway and there was an increase especially in artificial tanning.

Prof. Sinclair says: “We believe that sunscreen use does not directly lead to melanoma, but UVA exposure does. The Melanoma Epidemic is a reality. Sunscreen preparations are not the magical answer in the fight against melanoma and the irresponsible use of these preparations can worsen the problem.”
