Science is the future: SANRAL expands its UFS maths and science investment programme

The Science-for-the-Future (S4F) programme is fundamental to generating the required pipeline for technologically skilled entrepreneurs and workers by focusing on Mathematics and Science support to learners, teachers, and parents.

This is according to the South African National Roads Agency Limited (SANRAL) Chief Executive Officer, Skhumbuzo Macozoma, who delivered a keynote address at the Annual Science for the Future Summit held at the University of the Free State (UFS) on 20 September.

The S4F is a partnership between the UFS and SANRAL, with the fundamental purpose to train Maths and Science teachers and to support learners and parents. The programme has now been extended to six other universities, namely Nelson Mandela University and Walter Sisulu University in the Eastern Cape; the University of Limpopo, University of KwaZulu-Natal, and the two recently established universities, the University of Mpumalanga and the Sol Plaatje University in the Northern Cape.

Dr Cobus van Breda, the Programme Director for the UFS S4S, said they developed the Family Math and Key Concepts in Science programmes to address issues that prevent learners from excelling in these critical subjects. It seeks to improve the content knowledge of teachers and provide them with more skills-teaching resources.

Macozoma said: “I am proud and deeply honoured to stand before you today in the strength of a successful 10-year partnership with the University of the Free State which we are celebrating here today, together with the hosting of the Annual Science for the Future Summit.” More than 300 teachers attended the summit.

Planning for the future

He indicated that SANRAL's long-term strategy, Horizon 2030, instructed the development of a new human-resources strategy for the organisation, which has identified three pillars that underpin SANRAL's human-capital development initiatives, namely people, skills, and performance.

“The strategic opportunities identified by SANRAL include capitalising on the opportunity presented by the digital revolution to create a new generation of technologically skilled entrepreneurs and workers; returning to good and ethical governance in both the public and private sectors; bringing back the prestige of serving the citizens of SA through state institutions: fashioning SANRAL as an employer of the future and delivering technical skills to address the glaring skills gap in engineering and other domains,” he said.

Macozoma stated that SANRAL has also decided to review and rationalise its support to institutions of higher learning in order to grow the footprint of its support programmes, increase the impact, and ensure equity.

Beyond this, he stated that SANRAL wanted to ensure that learners are equipped with fundamental competencies that are essential to complement academic teachings, including critical thinking, creativity, collaboration, communication, information literacy, media literacy, technology literacy, and flexibility.

Facing 4IR head on

Macozoma said the most important characteristics of the Fourth Industrial Revolution that must be taken into consideration by those who aim to survive it, drive it, and benefit from it, is a smart customer – who is informed and dictates what services he/she wants and how they should be delivered; technology at the fingertips – which will enable rapid, real-time, borderless services to information, services, and technology as an enabler – bringing efficiency to logistics, mobility, medicine, education, industries, the economy, the military, global trade, and politics.

Working closely with school and society

UFS Rector and Vice-Chancellor, Prof Francis Petersen, said the university has an important responsibility to generate knowledge that will impact society positively.

“We have a role to work closely with our schools and society so that we can understand each other’s needs,” he said.

“We need to strengthen collaboration with all our partners so that we can travel further and make an impact in our society,” said Prof Petersen.

One of the participating teachers in the S4F programme, Grace Molante, from a primary school in Zastron, said: “It is programmes such as these that instil hope in us as teachers. Some learners could find Maths and Science very difficult and challenging subjects, but this programme makes problem solving more enjoyable and practical.”

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.”
