A VUCA environment reflects a state of the external world, or external to the leader, community, or nation, as much as it seems to reflect an internal frame of mind. The constant pressure to lead, while being uncertain about the outcomes of your decisions and even fearful of not being in control all the time, are some of the hallmarks of a VUCA world. A good way of thinking about this concept is to view it as the ‘new narrative’ – the volatility, uncertainty, complexity, and ambiguity inherent in today’s world.

Leaders in the 21st century need to steer a country securely through unparalleled, challenging, and stormy circumstances such as food insecurity, political unrest, migration and refugee issues, unemployment, divided societies and prejudice, global warming, and others. Against this introduction, it unfortunately appears as if there is an increase in VUCA problems in the 21st century, and leaders often fail in their attempts to provide solutions to these demanding circumstances. Indeed, it appears as if leaders in the 21st century are actually contributing to VUCA environments. So-called ‘state capture’ and the ‘gangster state’ in South Africa, ‘make America great again’ and ‘America first’ , the Brexit no-deal option, ‘trade wars’, and ‘the deadly coronavirus’ are examples of when leaders did not appear to solve challenges, but rather to intensify them. 

This is the backdrop against which the book, Chaos is a Gift? Leading Oneself in Uncertain and Complex Environments, has been conceptualised – indeed to debate the opportunities that exist amid this chaos. 

Three UFS women academics contributed to this book.

Dr Martha Harunavamwe (Department of Industrial Psychology) has written a chapter on resilience and agility in Zimbabwean higher education.Dr Mareve Biljohn (Department of Public Administration and Management) has written a chapter on leading the self in South Africa’s VUCA local government environments. Prof Liezel Lues (Department of Public Administration and Management) has written a chapter on South Africa’s surviving VUCA environment. She is also one of the editors of the book.

The endorsement written by Prof Petersen, reads: There are various books on leadership, but this book, in navigating today’s volatile, uncertain, complex and ambiguous (VUCA) environment, presents chaos as both an opportunity and possibility in developing ‘selfcare practices’ in leading oneself. Leaders must have the cognitive flexibility to adapt to the unknown in the midst of chaos (and a crisis). Through making sense of leadership approaches in different environments, including the business, private, academic and public sectors, as well as in conflict/post-conflict situations, the book provides a deep insight into leading oneself effectively with innovation and empathy in a VUCA environment – an excellent contribution to self-leadership.

The book, published by KR Publishers, will be launched on 27 August 2020. Prof Ebben van Zyl, together with Prof Lues, are the editors of this book: Van Zyl, E, Campbell, A and Lues, L. ed.

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.
