Peace Leadership: Self-Transformation to Peace is about a kind of leadership that puts peace first.

A young democracy such as South Africa is defined by a desire for better relationships, interconnectedness, inclusivity, cohesion, justice and a shared understanding. 
Peace Leadership: Self-Transformation to Peace offers a practical framework for all leaders, as well as for the average person on the street, on how to achieve this aspiration. 

A desire for peace

“It is every human’s desire to experience peace and to facilitate that peacefulness we need peace leaders.” The book offers strategies which leaders can apply to maintain and restore peace in conflict-ridden regions such as Bosnia, according to Martha Harunavamwe of the University of the Free State’s (UFS) Department of Industrial Psychology, who contributed two chapters to the book. The text also offers peace strategies to communities outside conflict-ridden regions. 

The written work explores ways in which the 21st century leader has the power to influence a nation towards or away from peace, the possibilities of restoring relationships, as well as how social systems can be tailored in the best interest of citizens for the purpose of conflict resolution.

The building blocks

Peace Leadership: Self-Transformation to Peace is built upon a three-phase foundation. “Moving through different phases, leading self, leading with others and leading your community will enhance self-transformation to the creation of peace.” 

Through cycles of action, reflection, learning and adaptation, peace leaders will improve on efforts to obtain peace,” said one of the editors and author of seven chapters, Prof Ebben Van Zyl. These building blocks model a more civilised and flourishing world in which the financial, political, health and education, human security, and legal needs of the community are served, thus creating a peaceful society.

Prof Van Zyl who is also from the Department of Industrial Psychology, edited the book, with Dr Andrew Campbell of the International Peace and Leadership Institute in the US.

Leaders are in the eye of the beholder

Two chapters of the book were written from a governance perspective. In her contribution, Prof Liezel Lues of the UFS Department of Public Administration states that there are large communities of peace leaders, considering they encompass all those who contribute towards nation-building, be they politicians, singers, actors, or business owners.

The importance of peace leaders should never be underestimated. If anything, scholar-practitioners, educators, academics, researchers, leadership development fraternities, peace organisations, negotiators, think-tanks, the diplomatic corps, government institutions, non-governmental organisations, consultants or advisors, security companies, the private sector and trade unions, should strive to become fluent in the concepts advocated for in Peace Leadership: Self-Transformation to Peace.

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.
