Prof Nompumelelo Zondi has been appointed as Vice-Dean: Research and Postgraduate Studies in the Faculty of The Humanities at the University of the Free State (UFS). Prof Zondi assumed this new role on 1 March 2024 after serving as the Head of Department for African Languages at the University of Pretoria for seven years. “I consider this appointment as an opportunity of growth and learning more about higher education and the Faculty of The Humanities at large,” she said.

Prof Zondi indicates that part of her role is to spearhead the UFS Vision130 within the Faculty of The Humanities, and to ensure that the faculty assists the institution in becoming research-led, student-centred, and globally impactful. 

Motivation for assuming this role

One of the primary reasons that led her to consider this role is sharing the knowledge she acquired as part of the Fulbright South African Research Scholar Programme. As a result of that experience and exposure, which went beyond the Ohio State University, she felt it befitting to implement some of the insights she acquired on a bigger scale. Therefore, even though she was impactful in her previous role, Prof Zondi believes that this is an exceptional and more desirable platform to do so. “I feel that I will have easier access to departments within the faculty, while also encouraging and supporting interdepartmental and faculty collaborations,” she explained.

A significant component of Vision 130

He believes that the elements that make up Vision 130 are interrelated. While she considers research central to Vision 130 – as she begins her journey at the UFS, she feels students deserve to be nurtured to further contribute to the university’s impactful research. Thus, student-centredness is the way to go. “I believe that students must be major role players in this Vision130; we must include them in the interactions and discussions that are part of the university’s strategic plan as well as in decision-making processes,” she said. As such, according to Prof Zondi, the more the faculty and the institution care for the students and involve them in Vision130 and in collaborations, the more research outputs the university will achieve.

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.”
