Dr Ehlers was appointed to serve on the National Forensic Oversight and Ethics Board of 10 members for a second term, based on her knowledge in the field of forensic sciences.

Dr Karen Ehlers from the Department of Genetics at the University of the Free State (UFS) was elected as a member of the National Forensic Oversight and Ethics Board (NFOEB) for a second term.

Dr Ehlers has been appointed to the board of 10 members based on her knowledge in the field of forensic sciences. She is currently conducting research focusing on the forensic application of Y-STR markers, the statistical analysis of DNA profiles, and touch DNA.

Making valuable contributions
Her expertise in the field of forensic genetics assists the board – which also handles complaints about alleged violations relating to the abuse of DNA samples and forensic DNA profiles – to oversee the operations of the Forensic Science Laboratory and the National Forensic DNA Database (NFDD). 

“The knowledge I gained from my current research at the UFS has enabled me to make valuable contributions to the board and its recommendations to the Minister of Police,” says Dr Ehlers. 

In her first term as member of the Board – following regular tracking and analysis of reports, the Board noted an increase in the number of outstanding forensic investigative leads – (hits on the National Forensic DNA Database) that were not followed up.

“After we made enquiries, it was determined that the provincial task teams that were to follow up on the leads, were ad hoc structures that lacked the necessary resources. The Board addressed this shortfall by engaging with various stakeholders and helping to establish permanent structures, called Forensic Investigative Units, with dedicated resources – both human and material – to effectively follow up on all forensic DNA investigative leads. The finalised Regulations were published for comment in the Government Gazette on 27 March 2020,” says Dr Ehlers.

Lowering SA crime rate
While serving on this board, she is ensuring that South Africa has a functioning DNA database that contributes to lowering the crime rate in the country. “As a member of the board, I hope to add value to its functioning. I feel that in the future, science will play an even bigger role in crime prevention, detection, and the solving of crimes,” she states.

Dr Ehlers is Programme Director of the Forensic Sciences Programme in the Department of Genetics. She teaches the Crime Scene Management module to second-year students and supervises seven honours, five MSc, and three PhD students. 

Besides her appointment as member of the NFOEB, she values the work she is doing with her students. “The highlight of my career was when my first group of BScHons students in Forensic Genetics graduated and were shortly thereafter appointed by the Forensic Sciences Laboratory as DNA analysts,” she says.

It is better for Super Rugby teams not to have the ball, which also leads to reduced overall playing time in matches.

This observation is from a study by the University of the Free State on the difference between winning and losing teams. Statistics between 2011 and 2015 show that Super Rugby winning teams kick more and their defence is better.

These statistics were applied by Riaan Schoeman, lecturer in Exercise and Sport Sciences, Prof Derik Coetzee, Head of Department: Exercise and Sport Sciences, and Prof Robert Schall, Department of Mathematics and Actuarial Sciences. The purpose of the study, Changes in match variables for winning and losing teams in Super Rugby from 2011 to 2015, was to observe changes. Data on 30 games (four from each team) per season, supplied by the Cheetahs via Verusco TryMaker Pro, were used.

About two minutes less action
“We found that the playing time has decreased. This is the time the ball is in play during 80 minutes,” says Schoeman. In 2011, the average playing time was 34.12 minutes and in 2015 it was 31.95.

“The winning team has less possession of the ball and doesn’t want it. They play more conservatively. They dominate with kicks and then they play,” says Prof Coetzee, who was the conditioning coach for the Springboks in 2007 when they won the World Cup.

Lineouts also more about kicking
As a result, the number of line-outs also increased (from 0.31 per minute in 2011 to 0.34 in 2015) and the winning teams are better in this regard.

“The winning team has less possession of the ball
and doesn’t want it. They play a more conservative
game. They dominate with kicks and then they play.”

Schoeman believes that rule changes could also have contributed to reduced playing time, since something like scrum work nowadays causes more problems. “When a scrum falls, the time thereafter is not playing time.”

According to Prof Coetzee, rucks and mauls have also increased, (rucks from 2.08 per minute in 2011 to 2.16 in 2015 and mauls from 0.07 per minute in 2011 to 0.10 in 2015). “The teams that win, dominate these areas,” he says.
