UFS Division of Student Affairs plans to extend their annual research colloquium to involve other universities, establishing the university as a pioneering institution of higher education and learning.
The annual University of the Free State (UFS) Division of Student Affairs Research (DSA) Colloquium aims to promote a culture of research embedded in data-driven and evidence- based practices in the field of Student Affairs. The purpose of the annual colloquium is to create a safe, enjoyable space for staff members to share their experiences, knowledge, research and practices.

The 2020 Student Affairs Research Colloquium was the first virtual Research Colloquium held by the university. As noted by DSA Researcher Ruben Langenhoven, this year’s theme Virtually Human: Connecting Meaningfully in a Digital World was inspired by the challenging times we live in, and thus commemorated the resilience and adaptability UFS Student Affairs practitioners, academic staff and students. 

As most of the projects and programmes in the DSA were negatively impacted, the Colloquium was threatened by a lack of “hard data” emanating from the 2020 academic year. The division consequently decided to reframe the colloquium by profiling distinct human voices that focused on qualitative experiences. As such, this Colloquium comprised of numerous sections where the emphasis was placed on shared experiences and shared understanding where UFS staff members and students discussed the challenges they faced in the last six months.

DSA staff engaged one another with staff and student-centered lived experiences, and professional staff development sessions that visited the impact of technology on their psychological well-being and how to improve their relationship with technology in light of the COVID-19 pandemic. Also forming part of the programme that will inform the future of the division going forward, reflected DSA success-story presentations of the past year. 

The colloquium proved as beneficial for the DSA and the entire institution in its pursuit of a research-based working approach within the Student Affairs discipline.

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
