Ullrich, Senior Lecturer in Interdisciplinary Theology: Historical and Constructive Theology, obtained a Y1 rating. Bottom left: Prof Maria Tsakeni, Associate Professor in the School of Mathematics, Natural Sciences, and Technology Education, Prof Matildie Wium, Associate Professor in the Odeion School of Music, and Dr Weldemichael Tesfuhuney, a senior lecturer in the Department of Soil, Crop, and Climate Sciences, all obtained a C2 rating.

The list of National Research Foundation (NRF)-rated researchers at the University of the Free State (UFS) is growing, with 22 researchers recently receiving their first NRF rating, and 14 others obtaining new ratings after re-evaluation. This list is expected to grow even more with results slowly filtering in.

Profs Jan van der Watt, Research Fellow in the Department of Old and New Testament Studies, and Felicity Burt from the Division of Virology and SARChI Research Chair in vector-borne and zoonotic pathogens, are the latest NRF B1 rated researchers. While this is Prof Van der Watt’s first NRF rating, Prof Burt has increased her NRF rating from B3 to B1. The UFS now has 10 B1 rated researchers.

In addition to the new rating of Profs Burt and Van der Watt, the UFS also boasts seven new C1 rated researchers, 14 new C2s, five new C3s, seven new Y2s and one Y1 and B3 rated researchers respectively.

Among the researchers who obtained their first NRF ratings are Dr Bimo Abraham Nkhata, Senior Lecturer at the Centre for Environmental Management; Dr Yolandi Schoeman, Senior Lecturer in the Centre for Mineral Biogeochemistry; and Dr Angélique Lewies, Senior Lecturer in the Department of Cardiothoracic Surgery, who has this year been nominated for the prestigious 2023/2024 NSTF-South32 Awards, popularly known as the “Science Oscars” of South Africa. Dr Nkhata obtained a NRF rating in the C2 category, while both Drs Schoeman and Lewies obtained a Y2 rating.

An honour to be among rated researchers

Other researchers who obtained their first NRF rating include Dr Monique de Milander, Senior Lecturer in the Department of Exercise and Sport Sciences, who obtained a C3 rating and Prof Maria Tsakeni, Associate Professor in the School of Mathematics, Natural Sciences, and Technology Education, who received a C2 rating.

Dr De Milander, a Kinderkineticist who works with the motor development of young children, says she was very surprised to obtain a C3 rating. “I feel honoured receiving this NRF rating. To know that other researchers are reading my work and finding it relevant. It takes a lot of dedication and patience, since this is an endurance race and not a sprint. You need to work many hours, read a lot of new articles and write the articles themselves.

“In addition, collecting the data is not always possible without the assistance of our students at the Department of Exercise and Sport Sciences as fieldworkers. I would like to acknowledge them because without them my research projects would not always be feasible. Furthermore, the publication process is also timeous, thus a lot of time elapses before you start to see the results of your work,” explains Dr De Milander.

According to her, the current project for her NRF rating is the assessment of motor development, attentional deficit hyperactive disorder, anthropometry and academic performance in low- and high-socio-economic primary school learners in Mangaung.

Prof Tsakeni, whose research focuses on the design and implementation of innovative instructional strategies and curriculum innovations in science classrooms, says she is honoured to be among the rated researchers. “The recognition motivates me to continue pushing myself to climb the ladder of rated researchers. The rating makes me feel affirmed to continue with my research work. I am grateful to the Faculty of Education, the UFS, and the NRF for giving me the opportunity and support.”

She would like to upscale the impact of her research by engaging in large-scale studies, international comparative studies, international collaborations, and one day, be a visiting scholar at some prestigious universities.

“The innovations in science classrooms include integrating inquiry-based practical work, education for sustainable development (ESD) and STEM education. The instructional strategies include inquiry-based learning and integrating educational technologies in the classrooms,” says Prof Tsakeni.

Recognition for long-term academic work

Newly C2 rated researcher, Dr Weldemichael Tesfuhuney, a senior lecturer in the Department of Soil, Crop, and Climate Sciences, says: “As an agrometeorologist by profession, I feel a profound mix of pride and motivation after receiving NRF-rating recognition for my long-term academic work.

“This acknowledgment validates my years of dedication in understanding the intricate relationship between meteorology and agriculture. It boosts my confidence and reaffirms my commitment to advancing my academic and research goals.

“Such recognition is a pivotal moment for me; it serves as a powerful reminder of the impact of my research on agricultural practices, particularly in addressing the challenges posed by climate change in arid and semi-arid regions.”

Dr Tesfuhuney, whose research deepens understanding of how meteorological patterns affect agricultural practices, making a significant contribution to the field of Agrometeorology, has established a robust research portfolio focused on the challenges of meteorology and agriculture in arid and semi-arid regions. He has spearheaded several long-term research initiatives, including In-field Rainwater Harvesting (IRWH) techniques, intercropping practices, micrometeorology, and crop modelling simulations, all aimed at improving crop productivity for smallholder farming communities in rural areas.

Currently, Dr Tesfuhuney is expanding his research on underutilised crops in the region, focusing on how these crops can help smallholder farmers adapt to the impacts of climate change while improving nutritional security.

Work on the right track

Dr Calvin D. Ullrich, Senior Lecturer in Interdisciplinary Theology: Historical and Constructive Theology, who obtained a Y1 rating, says though there is much talk in South African academia about the necessity of an NRF rating which is not always positive (at least in the broader humanities), the NRF does have its strengths.

“I think it pushes one to critically consider one’s work as a whole; to reflect on its current shape and to identify lacuna within a broader trajectory. There is something generative about this process in and of itself. Feelings of relief but also of affirmation then: a rigorous peer-review system which acts as a metric, according to which one might be able to say, ‘my work is somehow on the right track’ — I think there is certainly value in that.”

According to Dr Ullrich, pursuing your research and making critical interventions into your field, means the rating can follow as a necessary consequence. Research for him, he continues, like most academics, is deeply personal and exhilarating, and so acquiring the rating can also be seen as just another internal aspect of the research process as opposed to being contingent to it.

He has several research projects currently in the research pipeline including smaller writing projects relating to eco-phenomenology and eco-theology and political theology in South Africa. A larger project, scheduled to begin later next year and continuing for the next three years (2025-2028), involves a more intense investigation of the social dimensions of ‘affects’ and how this could be deployed within the specific social context of faith communities.

It’s humbling

For Prof Matildie Wium, Associate Professor in the Odeion School of Music, her first C2 rating is not only an honour for her contribution to her field, but also a humbling moment, because the experience of applying for a rating makes clear how much room remains for growth.

Her research has two main focus areas: (a) 20th-century South African art music, studied from an analytical-hermeneutic perspective, and (b) the musical practices and experiences of mid-19th-century female opera singers in London, studied by means of archival documents.

“I am currently working on converting conference papers I had delivered recently into articles, mainly on the South African art music side of my endeavours. There are papers about Mimi Coertse (in collaboration with my colleague Dr Albertus Engelbrecht), Hubert du Plessis’s Opus 24 (in collaboration with my past student Dr Melissa Gerber), and Michael Mosoeu Moerane’s tone poem Fatshe la Heso under development.

“I am also co-writing a paper analysing some items from ethnomusicologist Gerhard Kubik’s archive of Àló (Yoruba storytelling) with my colleague Dr Joseph Kunnuji,” says Prof Wium.

Dedication, resilience, and strategic focus

Dr Andronicus Akinyelu, Lecturer in the Department of Computer Science and Informatics, called his first Y2 rating incredibly rewarding as it reaffirms his hard work and perseverance have not been in vain. “It also serves as a great source of motivation for me to continue pushing boundaries and striving for excellence in my academic and research pursuits. I am deeply grateful to God for this achievement. I am delighted to have been successful. It is an important milestone in my academic journey,” he says.

According to him, achieving an NRF rating requires a combination of dedication, resilience, and strategic focus. It involves publishing high-quality research in top-tier journals, supervising postgraduate students, and contributing significantly as a first or corresponding author on various projects.

“My research spans multiple cutting-edge areas, including machine learning, deep learning, computer vision, medical diagnosis, sustainable agriculture, and responsible artificial intelligence (AI). Currently, I’m collaborating with international researchers to develop deep-learning techniques that predict treatment responses in cancer patients.

“This research has the potential to significantly advance personalised medicine by enabling more accurate and timely interventions. Additionally, I am deeply committed to promoting responsible AI by developing frameworks and models that prioritise ethics in AI systems,” says Dr Akinyelu.

Prof Vasu Reddy, Deputy Vice-Chancellor of Research and Internationalisation says: “Congratulations to all our newly rated researchers. We are expecting more in the coming months as the results of applications slowly filter in. We are extremely proud of our rated researchers for the recognition they have received. This is in large part the result of their contribution to producing high-quality research. There are many benefits that accrue to our researchers who are rated, namely an investment in their scholarship, including UFS support, as well as opportunities to further enhance their academic trajectory.”

Bloemfontein's quality of tap water compares very favourably with bottled water
2009-08-04

The quality of the drinking water of five suburbs in Bloemfontein is at least as good as or better than bottled water. This is the result of a standard and chemical bacterial analysis done by the University of the Free State’s (UFS) Centre for Environmental Management in collaboration with the Institute for Groundwater Studies (IGS).

Five samples were taken from tap water sources in the suburbs of Universitas, Brandwag, Bain’s Vlei, Langenhoven Park and Bayswater and 15 samples were taken of different brands of still and unflavoured bottled water. The samples were analysed at the laboratory of the IGS, while the interpretation of the analysis was done by the Centre for Environmental Management.

“We wanted to evaluate the difference in quality for human consumption between tap water and that of the different brands of bottled water,” said Prof. Maitland Seaman, Head of the Centre for Environmental Management.

“With the exception of two samples produced by multinational companies at their plants in South Africa, the different brands of bottled water used for the study were produced by South African companies, including a local small-scale Bloemfontein producer,” said Prof. Seaman.

According to the labels, the sources of the water vary from pure spring water, to partial reverse osmosis (as an aid to standardise salt, i.e. mineral, content), to only reverse osmosis (to remove salts). (Reverse osmosis is a process in which water is forced under pressure through a pipe with minute pores through which water passes but no – or very low concentrations of – salts pass.)

According to Prof. Seaman, the analysis revealed some interesting findings, such as:

• It is generally accepted that drinking water should have an acceptable level of salt content, as the body needs salts. Most mineral contents were relatively higher in the tap water samples than the bottled water samples and were very much within the acceptable range of drinkable water quality. One of the bottled samples, however, had a very low mineral content, as the water was produced by reverse osmosis, as stated on the bottle. While reverse osmosis is used by various producers, most producers use it as an aid, not as a single method to remove nearly all the salts. Drinking only such water over a prolonged period may probably have a negative effect on the human physiology.

• The pH values of the tap water samples (8,12–8,40) were found to be slightly higher (slightly alkaline), like in all south-eastern Free State rivers (from where the water is sourced) than the pH of most of the bottled water samples, most of which are sourced and/or treated in other areas. Two brands of bottled water were found to have relatively low pH levels (both 4,5, i.e. acidic) as indicated on their bottles and as confirmed by the IGS analysis. The health implication of this range of pH is not significant.

• The analysis showed differences in the mineral content given on the labels of most of the water bottles compared to that found by IGS analysis. The possibility of seasonal fluctuation in content, depending on various factors, is expected and most of the bottling companies also indicate this on their labels. What was a rather interesting finding was that two pairs of bottled water brands claimed exactly the same mineral content but appeared under different brand names and were also priced differently. In each case, one of the pair was a well-known house brand, and the other obviously the original producer. In one of these paired cases, the house brand stated that the water was spring water, while the other (identical) “original” brand stated that it was spring water treated by reverse osmosis and oxygen-enriched.

• Nitrate (NO3) levels were uniformly low except in one bottled sample, suggesting a low (non-threatening) level of organic pollution in the source water. Otherwise, none of the water showed any sign of pollution.

• The bacterial analysis confirmed the absence of any traces of coliforms or E.coli in any of the samples, as was also indicated by the bottling companies. This is very reassuring. What is not known is how all these waters were sterilised, which could be anything from irradiation to chlorine or ozone treatment.

• The price of the different brands of bottled water, each containing 500 ml of still water, ranged between R3,99 and R8,99, with R5,03 being the average price. A comparison between the least expensive and the most expensive bottles of water indicated no significant difference in quality. In fact, discrepancies were observed in the most expensive bottle in that the amount of Calcium (Ca) claimed to be present in it was found to be significantly different from what the analysis indicated (29,6 mg/l versus 0,92 mg/l). The alkalinity (CaCO3 mg/l) indicated on the bottle was also found to differ considerably (83 mg/l versus 9,4 mg/l). The concentration of Total Dissolved Salts (TDS) was not given on the product.

“The preference for bottled water as compared to Bloemfontein’s tap water from a qualitative perspective as well as the price discrepancy is unjustifiable. The environmental footprint of bottled water is also large. Sourcing, treating, bottling, packaging and transporting, to mention but a few of the steps involved in the processing of bottled water, entail a huge carbon footprint, as well as a large water footprint, because it also requires water for treating and rinsing to process bottled water,” said Prof. Seaman.
