The Afromontane Research Unit (ARU), the flagship research group of the University of the Free State (UFS) Qwaqwa Campus, has recently been granted R8,4 million to establish a Risk and Vulnerability Science Centre programme.

The Risk and Vulnerability Science Centre (RVSC) programme was established by the Department of Science and Innovation (DSI) as part of the Global Change Research Plan for South Africa and is funded by the DSI through the National Research Foundation (NRF). The RVSC will focus on the need to generate and disseminate knowledge about risk and vulnerability on global change challenges faced by local policy makers/ governance structures and communities in South Africa.

Invited to participate  

Dr Ralph Clark, Director of the ARU, says the UFS, together with the University of Zululand and the Sol Plaatje University, has been invited to participate in Phase 2 of the RVSC programme. Dr Clark was approached by the DSI (on referral from the South African Environmental Observation Network – SAEON) in February 2020 regarding the potential for establishing a RVSC at the UFS Qwaqwa campus.

Subsequent interactions were held between the UFS and DSI, and in March 2020, the UFS formally accepted the DSI invitation. It has since been agreed that the RVSC: UFS will be hosted as a RVSC under the ARU umbrella, with dedicated personnel embedded at the UFS in this regard (internal processes and reporting) but reporting directly to the NRF regarding the RVSC.

Interest and support welcomed

Dr Clark welcomed this interest and support from the DSI-NRF, saying that the funds will further assist the UFS in growing its excellent and growing research portfolio and building more research capacity on this traditionally undergraduate-focused campus. “The RVSC will contribute to much-needed solutions in an area marked by major sustainability challenges and will assist in moving Phuthaditjhaba away from its negative apartheid history towards becoming a sustainable African mountain city,” says Dr Clark.

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
