Dr Alice Ncube: ‘I desire to make a difference’

Dr Alice 2_web read more — 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.

Nanotechnology breakthrough at UFS

2010-08-19

Ph.D students, Chantel Swart and Ntsoaki Leeuw

Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil.

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast cells. With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
