Prof Philippe Burger, Dean of the Faculty of Economic and Management Sciences at the University of the Free State, appointed to the DHET Expert Panel on University Fees to help shape the future of tuition affordability and sustainability in South Africa.

Prof Philippe Burger, Dean: Faculty of Economic and Management Sciences at the University of the Free State (UFS), has been appointed as a member of a team that will represent Universities South Africa (USAf) in a DHET Expert Panel on University Fees. The panel, which comprises representatives from USAf, the DHET, and NSFAS, focuses on the affordability of tuition fees and the future sustainability of the sector, looking at potential solutions for tuition fees beyond the 2025 academic year. 

With more than 30 years of experience in higher education, mostly in management positions, Prof Burger understands the sector well. Combined with his expertise in macroeconomics, fiscal policy, and public sector economics and finance, he is uniquely positioned to make a significant contribution to this task team.

 

Universities matter

Despite the high national unemployment rate (32%), Prof Burger points out that unemployment is largely a problem of the unskilled. “The unemployment rate of people with university degrees is about 12%, much lower than the national average,” he notes. “South Africa has a large shortage of skilled labour, which it needs to grow the economy and improve lives.” He trusts that universities can fill this void, in addition to providing the thought leaders needed to take the country forward.

Although universities in South Africa are experiencing financial pressures, they continue to lift thousands of people to better lives each year. Universities make a profoundly positive contribution to the country and its population, and Prof Burger believes that once the public is fully aware of this, it will support broader discussions in favour of higher education.

 

The challenge

Universities face several cost pressures that are causing an increase in cost at a higher rate than consumer inflation, Prof Burger explains. “For instance, we buy equipment, software, and journal subscriptions that are all priced in US dollars. Affected by the exchange rate, these types of expenses have increased by much more than the price of consumer goods in South Africa over the past ten years.” According to Prof Burger, increased operational costs, coupled with constrained university income, necessitate a model that will provide universities with enough income to cover their costs while delivering quality education in the long run. 

 

The solution

“There is an argument for universities to become more efficient, and there is certainly room for universities to look at their cost structures, but there is also a limit to what we can do,” Prof Burger says. “It is important to stress that we cannot talk about the sustainability of universities and not contextualise it within a framework that seeks to deliver quality learning, teaching, and research. In the absence of that quality, we will not be able to address the skills shortages and thought leadership that the country needs. And that is the sustainability we need to talk about – the sustainability of quality education and scholarship,” he concludes.

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.

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.
