“May the best team win the 2019 BestMed Pedometer Challenge!” said LJ van Zyl, Pedometer Challenge ambassador.

Participants in the 2019 BestMed Pedometer Challenge will start improving their health step by step after the University of the Free State (UFS) challenged the Stellenbosch University, Central University of Technology, and North-West University (NWU) to an eight-week walking competition.

South African 400-metre hurdles record-holder and the Pedometer Challenge ambassador, LJ van Zyl, embraced the initiative as an alternative method to achieve fitness. “I am so tired of running and this is great way to stay fit,” he said during the official launch on the UFS Bloemfontein Campus on 5 April 2019.

Inter-institutional fight for fitness

Last year, the UFS Division for Organisational Development and Employment Wellness in the Department of Human Resources led a UFS-only challenge that saw 60 teams of staff members log a total of 54 606 km in eight weeks. The division then challenged the NWU.

Together, the NWU and UFS walked 132 000 km. This year, the UFS is taking it one step further by challenging two more institutions.
  
Leading the way

“We aim to get South Africa active – starting with the UFS – by embracing fitness and health ourselves,” said Arina Engelbrecht, UFS Employee Wellness Specialist.

Participants on all fitness and activity levels will gun for a 200 000 km target over 10 weeks.

The challenge kicked off on the Bloemfontein Campus with a 3-km walk at the launch, leaving 199 997 km between the four universities for the rest of the eight-week challenge.

On 14 May this year, Dr DW Bester received a DPhil in Statistics from the University of Oxford. The entire ceremony, which was held in the Sheldonian Theatre in Oxford, was conducted in Latin, as has been the case for the past 800 years.

Dr Bester completed his undergraduate studies and his honours degree at the University of the Free State (UFS). “At first, I was only planning to study for a master’s degree, but was privileged to get an opportunity to do a PhD as well. I didn’t think twice!” he says.

Studies at the University of Oxford


Universities in England do not require a master’s degree for PhD studies. With the help of Prof Max Finkelstein from the UFS Department of Mathematical Statistics and Actuarial Science, Dr Bester registered for the DPhil programme in Statistics directly after his honours studies.

“The title of my thesis was: Joint survival models: A Bayesian investigation of longitudinal volatility. It dealt with a problem in the medical field to determine the cause of stroke risk: is it the absolute level of blood pressure, or the volatility thereof? The analysis of this question led to interesting models which needed advanced application techniques. I had to study these techniques and write programmes for their application.

Although Dr Bester is working currently as the technical head of a company that calculates insurance for power stations, satellites, rockets, and cyber risks, he would like to continue working with his Oxford supervisor in future to make the techniques they have developed more accessible for researchers outside of the field of statistics.
 
“Studying at Oxford requires hard work, perseverance, and a lot of luck. Luck plays a big role, since there are no guarantees that hard work will ensure you a spot in one of the top universities.

Regarding his studies at Oxford, Dr Bester thinks back on his exposure to the GNU/Linux operating system, and free software. “I have seen how valuable this is for analyses in practice. I also had the privilege of meeting the father of free software, Richard Stallman,” Dr Bester says.

2011 Rhodes Scholar

He was elected as Rhodes Scholar in 2011. According to Dr Bester, who has been interested in Mathematics since high school, the Rhodes scholarship was something of a fluke. He applied for the Rhodes scholarship on the recommendation of Prof Robert Schall of the Department of Mathematical Statistics and Actuarial Science.

Role of the UFS in his successes


In addition to the continued support from the team of passionate professors and lecturers at the UFS, the actuarial degree at the UFS is fraught with statistics. Emphasis is also placed on Bayesian statistics. This was crucial to his studies at Oxford. According to Dr Bester, this topic is emphasised strongly in the international statistics community.

Dr Bester regards the work done by two of his lecturers, Michael von Maltitz and Sean van der Merwe, among his highlights at the UFS. Since our first year, they have created an atmosphere of camaraderie among the students. “I think this contributed to the success of everybody. They also make an effort to present topics outside of the syllabus regularly,” says Bester.
