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.

Is milk really so well-known, asks UFS’s Prof. Osthoff
2011-03-17

Prof. Garry Osthoff opened a whole new world of milk to the audience in his inaugural lecture, Milk: the well-known (?) food, in our Department of Microbial, Biochemical and Food Biotechnology of the Faculty of Natural and Agricultural Sciences.

Prof. Osthoff has done his research in protein chemistry, immuno-chemistry and enzymology at the Council for Scientific and Industrial Research (CSIR) in Pretoria and post-doctoral research at the Bowman-Grey School of Medicine, North Carolina, USA. That was instrumental in establishing food chemistry at the university.
 
He is involved in chemical aspects of food, with a focus on dairy science and technology. He is also involved in the research of cheese processing as well as milk evolution and concentrated on milk evolution in his lecture. Knowledge of milk from dairy animals alone does not provide all the explanations of milk as food.
 
Some aspects he highlighted in his lecture were that milk is the first food to be utilised by young mammals and that it is custom-designed for each species. “However, mankind is an opportunist and has found ways of easy access to food by the practice of agriculture, where plants as well as animals were employed or rather exploited,” he said.
 
The cow is the best-known milk producer, but environmental conditions forced man to select other animals. In spite of breeding selection, cattle seem not to have adapted to the most extreme conditions such as high altitudes with sub-freezing temperatures, deserts and marshes.
 
Prof. Osthoff said the consumption of the milk as an adult is not natural; neither is the consumption of milk across species. This practice of mankind may often have consequences, when signs of malnutrition or diseases are noticed. Two common problems are an allergy to milk and lactose intolerance.
 
Allergies are normally the result of an immune response of the consumer to the foreign proteins found in the milk. In some cases it might help to switch from one milk source to another, such as switching from cow’s milk to goat’s milk.
 
Prof. Osthoff said lactose intolerance – the inability of adult humans to digest lactose, the milk sugar – is natural, as adults lose that ability to digest lactose. The symptoms of the condition are stomach cramps and diarrhoea. This problem is mainly found in the warmer climates of the world. This could be an indication of early passive development of dairy technology. In these regions milk could not be stored in its fresh form, but in a fermented form, in which case the lactose was pre-digested by micro-organisms, and the human population never adapted to digesting lactose in adulthood.
 
According to Prof. Osthoff, it is basically the lactose in milk that has spurred dairy technology. Its fermentation has resulted in the development of yoghurts and all the cheeses that we know. In turn, the intolerance to lactose has spurred a further technological solution: lactose-free milk is currently produced by pre-digestion of lactose with enzymes.
 
It was realised that the milks and products from different species differed in quality aspects such as keeping properties and taste. It was also realised that the nutritional properties differed as well as their effects on health. One example is the mentioned allergy against cow’s milk proteins, which may be solved by the consumption of goat’s milk. The nutritional benefits and technological processing of milk aroused an interest in more information, and it was realised that the information gained from human milk and that of the few domesticated species do not provide a complete explanation of the properties of milk as food. Of the 250 species of milk which have been studied, only the milk of humans and a few domesticated dairy animals has been studied in detail.
