Dr Alice Ncube says that since coming to South Africa and working with vulnerable communities in the disaster (risk) management field, she has gained extensive knowledge and perspectives on the real-life situations of humanity.

While working in human resources and industrial-relations management portfolios, Dr Alice Ncube saw a window of opportunity to get into research, focusing on the challenges that was threatening the human capital management sectors and the general operations of governments and the private sector. 

Today, Dr Ncube is teaching students and doing research in the Disaster Management Training and Education Centre (DiMTEC) at the University of the Free State (UFS), where she is a Senior Lecturer and Programme Director.

On 11 February – International Day of Women and Girls in Science – the UFS is celebrating Dr Ncube, who chose to be a scientist due to her desire to make a difference. 

Being a migrant facing several challenges in her host country motivated her to do her PhD on international migration, specifically on women from developing countries to other developing countries such as South Africa.

Her research also covers related topics, including social vulnerability and resilience, international forced migration, gender issues, climate change and adaptation, and sustainable livelihoods of disadvantaged communities.

Demystifying perceptions

“Many persons who do not reside in the country believe that South Africa is a land of opportunities – socially, politically, and economically – due to its position on the African continent. This all-round positive picture of the country painted to the outside world is the main reason for the huge inflow of migrants into the country,” believes Dr Ncube. 

She envisaged that her study would assist in demystifying the perception that migrants are those who come to a host country to take local jobs and put pressure on local resources.

“I felt that gender migration in this space is under-researched, particularly migration of women. Migration is not gender neutral, but gender biased, as evidenced by the 1960s and early 1970s, where terms such as ‘migrants and their families’ were coded to refer to male migrants and their wives and children. Although women were nearly invisible, there is evidence of them migrating as independent agencies and also taking along their families, including husbands,” she explains.

Exploring the coping and adaptation strategies that women employ in the host country, she found that although faced with many challenges, the migrant women cope and adapt well.

Her research as well as her work of more than 10 years with the vulnerable communities, including migrants, has established that the resilience of vulnerable communities is bigger than the intervention strategies that governments and other stakeholders envisage.

People are hungry for knowledge that will better their lives. – Dr Alice Ncube

Impacting lives

“Since coming to South Africa and working with vulnerable communities in the disaster (risk) management field, I have gained extensive knowledge and perspectives on the real-life situations of humanity, let alone in our continent and region,” she says.

She has worked with government departments at local, district, provincial, and national levels in an effort to change the conditions faced by poor, marginalised, and disadvantaged communities. Dr Ncube was also involved in community capacity-building activities through short courses and short learning programmes. 

She considers the training she has presented as one of the biggest achievements of her life. “People are hungry for knowledge that will better their lives.” 

“This has been so fulfilling to me as I have made an impact on the lives of the people,” says Dr Ncube.

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.”
