Jaco Peyper
Jaco Peyper, former Kovsie, will handle a quarter-final match at the Rugby World Cup. It will also be his 50th test match.
With the appointment of Jaco Peyper as referee there will be Kovsie alumni among the referees, players and coaches in the quarter-finals of the 2019 Rugby World Cup in Japan on 20 October.

Lappies Labuschagné will start on the flank for Japan in their clash against the Springboks on Sunday. Labuschagné, a former Shimla captain, is second on the list for tackles made in the tournament thus far.
In the Springbok camp there are former University of the Free State (UFS) students in Rassie Erasmus (head coach) and Jacques Nienaber (defence coach).

UFS alumnus Jaco Peyper has been entrusted with the whistle in Sunday’s other quarter-final between Wales and France. It will be a memorable match for Peyper as it will be his 50th test appearance as the 31st man on the field – making him only the third South African to achieve this feat.

Peyper, who is the only South African among the 12 referees at the tournament, made his World Cup debut in 2015 when he officiated the opening match. In total he has handled six World Cup encounters. 

His illustrious career has seen him become only the fourth referee in history to officiate in 100 Super Rugby matches earlier in the year, in which he also handled the final (his fourth Super Rugby final). Peyper scooped the SA Referee of the Year award in 2018 for a third time, a year in which he took charge of his fourth Currie Cup Final.

“The fact that he is only the third South African referee to take charge of 50 tests indicates what a special achievement this is. It takes years of hard work and dedication to reach this level as a referee, and to maintain this standard year-in and year-out is even more challenging as it requires one to produce effective performances consistently,” said Jurie Roux, the CEO of SA Rugby.

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
