The business world today is confronted with continuous disruptions and uncertainty. Organisations are challenged to think about digitalisation, innovation, and transformation to remain competitive. Leaders must be able to take everyone with them on a journey of continuous change.

This is according to Prof Peter Rosseel, Director of MCR Consulting (a spin-off of the University of Leuven in Belgium) and Affiliated Professor at the University of the Free State (UFS), who gave the lecture in the UFS Business School. The title of the lecture was The Golden Triangle of Vision-Leadership-Culture: why changing behaviour is so difficult and what you can do about it? and it was aimed at challenging leaders to deal with disruptions and uncertainty, the lecture equipped attendees with the skills to do so. 

Prof Rosseel challenged attendees to stretch their thinking. “Change management is not a human resource function, it is a leadership concern. Leaders who want to see a change in behaviour should create conceptual conflict.”

Conceptual conflict

Laughter was coupled with moments of silence as Prof Rosseel, a visiting professor at the University of Leuven in Belgium, took attendees on a roller-coaster ride. He alluded to five examples of conceptual conflict, statements that shook the room. 

  • Team building doesn’t work, it is a waste of money.
  • Stop giving presentations, people only remember 4% of what was presented.
  • Take the word ‘consensus’ out of your vocabulary.
  • You can measure all you want; it won’t change behaviour.
  • Training as a strategy to change an organisation is a very bad idea.

He believes that conceptual conflict is important for the development of the culture of an organisation.

In addition to creating conceptual conflict, leaders should negotiate with their teams. “There are three ways to go about this; inform, engage/empower, and observe the change in behaviour. People want to be informed on time, people want control, and people want to know why. Meet these terms and you are well on your way to observing the change in behaviour. People can agree to change even if they don’t support it, as long as they believe it is fair.”

An attendee posed a question to Prof Rosseel: “In South Africa, we have trade unions, and this leads to a consensus approach to decision-making. How do we do away with consensus in decision-making?” Prof Rosseel responded by saing: “That’s the context within which you operate. You can’t change the context. Play the politics but never compromise the strategy implementation.”

The golden triangle of ‘vision – leadership – culture’ provides a framework within which organisations can operate. Vision is the content, while leadership facilitates the change in behaviour, and culture is created through strategy implementation and cognitive dissonance.

About the speaker 

Prof Rosseel’s field of expertise covers strategy implementation, change management, cultural and digital transformation, leadership, and learning. He travels the world to help leadership teams and their organisations to change (80% of his time). 

He also teaches change management, and digital and organisational culture transformation to first- and second-year students in the Master of Biomedical Sciences, third-year Bachelor of Criminology students, and third-year Bachelor of Psychological and Educational Sciences students. In 2024, he will also teach a postgraduate course to engineers on the same subject matter. In South Africa, he teaches in the Faculty of Economic and Management Sciences (20% of his time).

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.
