Louzanne Coetzee ready to take shot at Paralympics title

For some athletes, the postponement of the Paralympics was a big frustration, but for Louzanne Coetzee it was a ‘blessing in disguise’.

According to the former University of the Free State (UFS) student and current Residence Head of Akasia on the UFS Bloemfontein Campus, she was more than happy to get another 12 months to prepare herself to the very best of her ability. She will be in action at the Tokyo Paralympics in the 1 500 m on Sunday (29 August 2021) and Monday (30 August). On 5 September, she will tackle the marathon. It is her second Paralympics.

“This is the most exited I have ever been for an event. It has been so long since I was able to compete on a high level. I think it is a blessing in disguise. It allowed me more time to prepare. I’m in a great state and I cannot wait,” she said.

In the 1 500 m, Coetzee will be guided by Estean Badenhorst. In the marathon she will run next to Claus Kempen, with whom she has completed a couple of marathons before.

“They are both very experienced and I’m fortunate to have such a great team with me. When you are running an event like the 1 500 m, you need to fully trust your guide with his decision making.”

“The main focus is the track item. I won’t put too much pressure on myself in the marathon. The prime goal is to gain experience in the longer distance, because that is where I’ll be shifting in the future,” she explained.

The South African 1 500 m record holder in the T11 classification (totally blind) clocked a personal best time of 4:51.65 in 2019. She is the world record holder in the 5 000 m; however, the item does not feature on the Paralympic programme.

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
