CEO of Toyota Free State Cheetahs delivers guest lecture during UFS visit

29 August 2024 | Story Anthony Mthembu | Photo Harmse Photography

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.

Harvard couple to present lectures on Biostatistics and Mathematics at the UFS

2015-12-07

Professor Donald Rubin

Prof Donald Rubin (John L. Loeb Professor of Statistics at Harvard University) and Elizabeth Zell (MStat - mathematical statistician in the Division of Bacterial Diseases) will visit the University of the Free State (UFS) where they will present lectures on their respective work.

Over his prestigious academic career, Prof Don Rubin’s 400 publications and 13 books have earned him around 180 000 citations at an h-index of 113. He is one of the most cited statisticians/mathematicians/economists/psychologists in the world over the last 10 -15 years. He has supervised 35 PhD candidates as sole-supervisor, 17 more as co-supervisor, with a further eight in the pipeline.

Prof Rubin who will meet with UFS academics in the Department of Mathematics and Actuarial Sciences will also deliver a lecture: Rerandomisation to improve covariate balance in experiments.

Randomised experiments are the “gold standard” for estimating causal effects, yet in practice, chance imbalances often exist in covariate distributions between treatment groups. If covariate data are available before units are exposed to treatments, these chance imbalances can be mitigated by first checking covariate balance before the physical experiment takes place. Provided a precise definition of imbalance has been specified in advance, unbalanced randomisations can be discarded, followed by a rerandomisation. This process can continue until a randomisation yielding balance according to the definition is achieved. By improving covariate balance, rerandomisation provides more precise and trustworthy estimates of treatment effects.

Prof Rubin received an honorary professorship from the Faculty of Natural and Agricultural Sciences at the UFS.

Elizabeth Zell

The lecture will take place on:
Date: Tuesday 8 December 2015
Time: 16:00
Venue: Albert Wessels Auditorium, Bloemfontein Campus

Zell earned her Master’s degree in Statistics at North Carolina State University, and for more than two decades, was an active bio-statistical researcher in various offices of the Centers for Disease Control (CDC). Since 2013, she has been the Principal Statistician and President of Stat-Epi Associates, Inc. Her 150+ publications have earned her 14 500 citations at an h-index of over 50. She is a Fellow of the American Statistical Association, and, in 2010, she received the Statistics Section Government Award for outstanding contributions to statistics and public health by the American Public Health Association. During her career at the CDC, she earned more than 20 CDC research awards and honours.

She will deliver two lectures at the UFS. The first is entitled A Potential Outcomes Approach to Documenting the Public Health Impact of the Introduction of PCV13 for the Prevention of Invasive Pneumococcal Disease. The topic of her second lecture is: Assessing the Effectiveness of Intrapartum Antibiotic Prophylaxis for Prevention of Early-Onset Group B Streptococcus Disease through Propensity Score Design

Elizabeth’s lectures will take place on:
Date: Wednesday 9 December 2015
Time: 10:45 and 13:00
Venue: West Block 111, Bloemfontein Campus
