Friends beat the odds by achieving second degrees together

Their friendship began in high school, where they were constantly told by teachers that they would not make it to university, but these best friends never gave up. On Thursday 21 April 2022, they received their honours degrees in the Faculty of Natural and Agricultural Sciences together during the afternoon ceremony of the University of the Free State’s April Graduations.

Lerato Mbongo and Opheleleyo Qwabe, who have been friends since Grade 9, said being picked on in class for not being the brightest learners brought them together and motivated them to work harder.Mbongo obtained a Bachelor of Agriculture Honours majoring in Wildlife Management, and Qwabe received a Bachelor of Agriculture Honours majoring in Agricultural Economics.

“We’ve always dreamed big, but if you had told us back then that we would one day be two-time graduates, we wouldn’t have believed it. During one of our Maths lessons back in Grade 9, our teacher went around asking the ‘smarter’ kids what they wanted to study after matric, but when he got to us, he said there was no point in asking because we wouldn’t make it that far anyway,” Qwabe said.

The friends, who both started at the university’s South Campus, said they were grateful for the UFS Preparation Programme, as it boosted both their marks and their confidence. “The programme helped us to believe in ourselves again, and also played a big role in helping us discover what we wanted to study. The courses we enrolled in really unlocked an unstoppable passion in us and helped us realise that nothing is impossible. Today, here we are celebrating 10 years of friendship, and our honours degrees. We’ve conquered once again, and we're sharing our victories together,” Mbongo said.

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
