Ross van Reenen, CEO of the Toyota Free State Cheetahs.
The Business School at the University of the Free State (UFS) recently hosted the CEO of the Toyota Free State Cheetahs, Ross van Reenen, for a guest lecture. Van Reenen presented the guest lecture in the Business School Auditorium on the UFS Bloemfontein Campus on 21 August 2024.
Reflecting on Van Reenen’s address
In a lecture addressed to an auditorium filled with UFS staff and students, Van Reenen’s talk was divided into several sections. Firstly, he spoke about the concept of the ‘black swan’ in reference to the book written by Nassim Nicholas Taleb, titled The Black Swan: The Impact of the Highly Improbable. Referring to Taleb’s book, Van Reenen defined a ‘black swan’ as a rare event that has a severe impact, and the occurrence of which people try to explain. He used some examples to explore this concept as well as its implications, including COVID-19 and its impact on the world, and the tragic death of the people in the Titanic disaster. However, he delved deeper into 9/11 and the extent of its impact, saying that “9/11 was a major wake-up call in the world economy”. Van Reenen highlighted how some companies such as Barclays, for which he previously consulted, had to work to be up and running after the collapse of the Twin Towers in 9/11.
In addition, Van Reenen’s lecture also touched on the importance of the first ninety days of a job after an individual has been employed. “Those first ninety days are crucial, as you have to establish yourself in a company where you are paid less than you are worth,” Van Reenen said. As such, he gave the audience insight into what they could focus on in that time frame. This includes focusing on the small wins, as well as ensuring that you are working at keeping the team together, as the team is an integral part of an organisation.
Van Reenen concluded his address by speaking about his time as the CEO of the Toyota Free State Cheetahs, including some of the decisions he took to ensure the success of the organisation.
Prof Tredoux turns theories regarding the formation of metals on its head

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.
The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.
This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.
Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.
The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.
For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.
“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”
Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
