Prof Johan Venter monitors an experiment during a ‘Chemistry magic’ demonstration at the launch of the new laboratory on the South Campus.

“This facility is proof of the belief, dedication, and willingness to create teaching and learning facilities, as well as the environment to secure successful studies for deserving students after their South Campus year, by laying a firm foundation.” These were the words of Francois Marais, Manager: Extended Curriculum Programmes, at the opening of a new Chemistry laboratory on the UFS South Campus. He added: “The culmination of this project is the result of sacrifice, hard work, and outstanding academic leadership.”

The lab came into being as a result of a pressing need for laboratory space to accommodate Chemistry students on the Bloemfontein and South campuses. Elzmarie Oosthuizen, Manager: Teaching and Learning in the faculty, discerned this need, formulated a plan, and submitted it to the Dean of the Faculty of Natural and Agricultural Sciences, Prof Danie Vermeulen. Since limited funds were available and a new building was not financially feasible, Mrs Oosthuizen suggested converting existing space on the South Campus into an appropriately equipped laboratory to relieve the additional strain on existing laboratories on the Bloemfontein Campus.

At the launch of the lab, Prof Vermeulen thanked the management and team effort of the Department of Chemistry for their enthusiasm, optimism, and positive attitude, which made it possible to establish the laboratory in a very short time.

Prof Francis Petersen, Rector and Vice-Chancellor of the University of the Free State (UFS), said: “This lab is a masterpiece of the South Campus. The University of the Free State is on a mission to improve and enhance our level of excellence in the field of academia. That is what academia is all about   to continually strive to be the best. That is why our vision is to be a research-led, student-centred, and regionally engaged institution.” He further said the value system through which this would be achieved, was development within the context of a social-justice framework.

Prof Walter Purcell, Head of the Department of Chemistry, mentioned that this new lab would bring about a 23% reduction in the number of first-year students who have to perform Chemistry practicals each week, resulting in fewer sessions being presented per week. “This has eliminated the need for evening sessions and the associated travel and safety issues for students who have to commute.”

By the launch date on 28 September 2018, 1 326 practical sessions had already been presented in the new laboratory.

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
