UFS Council member makes contributions in books on leadership and responsive universities

Dr Millard Arnold, Council Member of the University of the Free State (UFS) and Senior Consultant at Bowman Gilfillan, recently contributed to a noteworthy book on leadership and a book on responsive universities. His experience as a journalist and later as a seasoned leader and keynote speaker positioned him well to participate in the book: The Book Every Upcoming, New, and Seasoned Leader Needs to Read – Lessons From Leading Business Minds and Thought Leaders.

From surviving to thriving

Incorporating collective leadership wisdom for both the leaders of tomorrow and the leaders of today, the book is full of lessons, insights, pep talks, advice, and direction for building your own style and approach to great leadership, and not to shy away from the ecstasy (and sometimes agony) of becoming a significant leader. Packed with the contributions of 48 authors, the book is the antidote to the lack of mentorship in the field. Authors include Brand Pretorius, Edwin Cameron, Marnus Broodryk, Nyimpini Mabunda, and Roze Phillips – to name a few.

Giving problems to solutions

Dr Arnold’s contribution focuses on fishing out the valuable leadership principles from the sea of leaderships that we are drowning in. “I have found myself in positions of leadership and have had to develop a number of thoughts on leadership which have helped guide me in determining how best to lead,” he writes. This guided him to discover the true essence of leadership, which is problem solving. He asserts that “if there are no difficulties to overcome, no problems to resolve, the leadership is unnecessary”. Leadership has its genesis in problems, he believes.

Effective leaders make things happen

Among the profound insights that Dr Arnold shares, he highlights the notion that great leaders must understand the problem and have the vision to see the solution. Inevitably, this necessitates the leader to take some risks and to persuade others to get on board. This is only possible if the leader has integrity and ultimately deliver on the promise made. He advises leaders to “ask good questions, listen to the answers, assess the reality, be empathic, and spend a great deal of time on self-reflection”.

Universities must remain relevant

Dr Arnold also contributed a chapter titled, Poverty, Inequity and Decolonisation: Are Business Schools Responsive to the Challenge? in a book by Chris Brink, The Responsive University and the Crisis in South Africa. The book brings together contributions on the issue of responsiveness from several international university leaders. Dr Arnold’s chapter presents an overview of the impact of colonialism and capitalism on the African mind set and stresses how different South African business schools have responded to the task of being responsive to the challenges confronting the country. It argues that, if carefully managed, business schools can, and should be, vehicles to promote and facilitate positive and constructive change.

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.
