Kovsie students in the process of building their Eco vehicles
The countdown has begun to the Kovsie-ACT music festival that will take place on 17 February 2018 at the Cross Country Fields.
With just a few days left before the main event where students and the community will be wowed by performances from the likes of Prince Kaybee, Jack Parow and Shekinah, students can look forward to the "Social Cohesion" college festivities namely: the West College Project Neon party, East College Graduation party, Central College Yellow party, South College Feballoween party, North College Cowboys and Crooks party, and finally the Kovsie-ACT Fiesta Mexican party.
Each day leading up to the main event, senior on-campus residence students will be working on the building of their various Eco vehicles. Students will be grouped in their designated colleges at the UFS Rag Farm, with the support of the first-years, pending the Eco vehicle race that takes place on Friday 16 February 2018 from 13:00. The ACT office is working towards obtaining sponsors for the overall winners of the race. Their aim is to give the college that wins the race a-once-in-a-lifetime opportunity to attend an official international car race, where they will be represented by their residence committees. The following race criteria apply:
Race criteria:
| Drag race | Fastest time taken to cover distance wins |
| Slalom race | Fastest time taken to complete course minus penalties |
| Obstacle course | Fastest time taken to complete course wins (Obstacles will be introduced on the day, no preparation) |
| Three lap-race | No winner, just preparation for final endurance race but drivers must change each lap |
| Endurance race | Longest distance covered |
Students will also be working on art projects in the form of a canvas that must be made of waste materials such as plastic, scrap metal and/or sustainable organic materials. The work must be between three and five metres high and two to four metres wide. It should be durable and not perish if it is placed outdoors for a year. It must be accompanied by a manifesto that explains the theme and symbolism of the artwork so that the five colleges can effectively illustrate what is important to them and their community.
First-year students have also been assigned to participate in projects that engage with local secondary schools in the Bloemfontein area. The content of the projects will be directed through a short learning programme that will take place during the course of the year.
The Kovsie ACT team looks forward to the activities at the Rag Farm, and encourages students to attend and take part in their numbers. For more information about Kovsie ACT visit the UFS Rag page or the Ofm official website.
UFS alumnus receives PhD in Statistics from the University of Oxford

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.
