UFSAfricaWeek - Sharing a meal to celebrate Africa Day
Since the foundation of the Organisation of African Unity on 25 May 1963, the day has been renowned as Africa Day, celebrated widely across the world and particularly in Africa to signify Africa’s identity and unity.

As a build-up for Africa Day celebrations, the Student Representative Council’s (SRC) executive committee of the International Students Council collectively came up with the ‘Meal in a jar’ initiative. The purpose of this initiative is to reach out to the community, interact and promote unity as a way of celebrating Africa day. It is also to bring to life the sense of integration and inclusion for international students. “From the time one sets foot at the University of the Free State (UFS), the only community most of us will know is the UFS community,” said Andrei Tendai, the SRC International Students Council representative.
 
The international students’ council in collaboration with Elanja Children’s Initiative identified Heide Primary School in Heidedal for this project. Through the ‘Meal in a jar’ initiative, international students will have the opportunity to engage with the broader community outside the institution’s walls in a fun and unique way. Together with volunteers from House Kestell and other partners, the SRC on 24 May 2018 will prepare and share a meal in a jar with 130 learners.

“This project emphasises the efforts by the SRC to denote a significant shift from an attitude of international students’ isolation and exclusion, to an inclusive and open policy that encourages integration and the promotion of the right to equality,” said Tendai.
 
Celebrating Africa day is also about working towards an Africa that relies on the potential of its people, and whose development is people-driven especially for women, youth and children.

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
