Dr Regret Sunge – the newly rated NRF Y2 academic.

The University of the Free State (UFS) is proud to announce that Dr Regret Sunge, Lecturer in the Department of Economics and Finance within the Faculty of Economic and Management Sciences, has been awarded a prestigious Y2 rating by the National Research Foundation (NRF). This significant achievement highlights Dr Sunge's exceptional potential as a rising leader in the field of economics and finance.

The NRF Y2-rating is bestowed upon young researchers, typically under the age of 40 and within five years of obtaining their PhD, who have demonstrated considerable potential to establish themselves as leaders in their area of expertise. Dr Sunge's inclusion among the 3,8% of newly rated researchers in South Africa highlights the quality and impact of his work.

Dr Sunge expressed his excitement, stating, "I am thrilled to have received the NRF Y2-rating for the period 1 January 2025 to 31 December 2030. Receiving such recognition through this meticulous process in the field of Economics and Finance – which has a share of only 4,9% of total rated researchers – is even more amazing." He further emphasised the rigorous nature of the NRF rating process, and the insightful feedback received.

 

Factors contributing to this recognition

Dr Sunge attributes his success to a combination of personal dedication, collaborative efforts, and institutional support. His PhD thesis provided a strong foundation, with three of the five reviewed papers originating from this work. Subsequent research collaborations with international peers fostered during his PhD journey further enriched his research by integrating the critical fields of agricultural production and environmental sustainability. The growing number of citations his work has received speaks to its increasing relevance and impact.

The academic also acknowledged the significant influence of key individuals on his research journey, including his PhD supervisor, Prof Nicholas NgepahDr Delphin Kamanda Espoir – a research partner, and his postdoctoral host, Dr Calvin Mudzingiri.

Beyond academic research, Dr Sunge's engagement in research consultation with regional and international organisations has played a vital role. In 2022, he formed a team within the United Nations Young Economists Network (UN-YEN) to study Africa's macroeconomic growth. Additionally, he contributed as a research assistant to the Organisation of Economic Cooperation and Development (OECD) and the African Union Commission (AUC) for their annual Africa Development Dynamics (AfDD) publication.

Dr Sunge also highlighted the crucial institutional support he received from the University of the Free State, specifically the Faculty of Economic and Management Sciences (EMS) on the Qwaqwa Campus, where he was a postdoctoral research fellow at the time of application.

 

Impact of the NRF rating on research standing

The Y2 rating is already proving to be a catalyst for Dr Sunge's research endeavours. "It’s a motivator, I am more confident, and it has greatly enhanced my CV," he noted. He anticipates that this recognition will unlock opportunities for further collaborations and access to competitive research grants and funding programmes, both nationally and internationally.

Furthermore, Dr Sunge's achievement while based on the Qwaqwa Campus enhances the University of the Free State's reputation for supporting young researchers and fostering excellence across all its campuses. His rating serves as a significant source of inspiration for his colleagues on the Qwaqwa Campus, particularly within EMS, where NRF-rated researchers are still few. Dr Sunge hopes that his success will encourage colleagues in the faculty to pursue similar achievements through commitment, dedication, and collaboration.

 

Research focus and its importance

Dr Sunge's research primarily focuses on the intersection of agricultural production and environmental sustainability. His work addresses the critical challenge of ensuring food security amid the growing impact of climate change in a sustainable manner. Recognising the dual challenge of increasing agricultural output to combat food insecurity while mitigating climate change, his research aims to inform environmentally sustainable agrifood systems in South Africa and beyond.

Specifically, his research holds local relevance for Phuthaditjhaba, where livestock agriculture is a significant part of the local economy, with the potential to contribute to more sustainable livelihoods. Utilising a range of econometric methodologies, his research approach is adaptable to various fields of study, facilitating collaboration with researchers from diverse backgrounds.

Acknowledging the dynamic nature of research in economics, particularly in econometrics and data analysis, Dr Sunge emphasises the importance of continuous learning through conferences and workshops. He aims to further develop his econometric and critical thinking skills, as well as sharpen his writing abilities, to elevate his research to new heights.

 

Future research trajectory

Looking ahead, Dr Sunge envisions a research trajectory that combines academic rigour with impactful societal engagement. This involves identifying research problems, providing in-depth academic analysis, and developing solutions that directly benefit communities. His future includes initiating research-based interventions and conducting impact assessments. Achieving this vision necessitates securing research grants, supervising postgraduate students, and actively engaging in community initiatives.

 Over the next five years, Dr Sunge aims to transition from a Y2 to a C-rated researcher, a goal that requires careful planning to balance his research and teaching responsibilities. While committed to advancing his research, Dr Sunge remains passionate about teaching and ensuring that his research activities enhance, rather than detract from, his classroom engagement.

 Dr Sunge’s achievement of the NRF Y2-rating is a significant milestone, both for his personal career and for the University of the Free State. His dedication, collaborative spirit, and impactful research focus serve as an inspiration to colleagues and aspiring economists alike. As Dr Sunge eloquently stated, "My word to aspiring economists, especially from marginalised circumstances, is that with the right mindset, commitment and dedication, we can be counted."

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.”
