Kyla Dooley, runner-up in this year’s Three-minute thesis competition, wants to pursue a career working alongside police enforcement, using her knowledge of forensics to solve criminal cases and convict perpetrators.

When rapes and sexual assaults are committed, DNA evidence can play a large role in convicting the offenders. DNA evidence collected from sexual crimes can, according to Kyla Dooley, often be tricky to analyse.

Kyla has just completed her master’s degree, specialising in Forensic Genetics, at the University of the Free State (UFS). She not only thrives in this field – graduating at the top of the Faculty of Natural and Agricultural Sciences in 2018 when she was awarded the Dean’s Medal – but her work also brought her the runner-up position in this year’s Three-minute thesis competition. 

She talked about her research on the use of male-specific DNA in the analysis of DNA evidence collected after crimes of a sexual nature have been committed.

Explaining her research, Kyla elaborates: “In most cases, the victim is female, while the offender is male. Therefore, the evidence is often a mixture of male and female DNA and this can make it difficult to analyse the male DNA and match it to a male suspect.”

She believes the solution to this is to target male-specific DNA in analysis. “This eliminates all female DNA and simplifies the process,” says Kyla.

“Unfortunately, male-specific DNA technology is not currently used in South Africa, because the DNA regions tested to date haven’t shown much success in distinguishing between males in our population,” Kyla points out.

“The goal is now to use DNA evidence, to match it to a suspect, and have the confidence that it came from him and only him. Or else defence lawyers could argue that it came from someone else in the population,” she says.

Improving DNA evidence

Therefore, Kyla’s research focused on evaluating a new group of male-specific DNA regions, which are to be tested yet, to see if it would be a viable option for use in South Africa. 

“I achieved this by collecting DNA samples from men on campus, processing them to obtain DNA profiles, and then determining how well these regions can distinguish between the men. The results of my research demonstrate the potential of these DNA regions to improve the use of DNA evidence when investigating sexual assaults in South Africa,” says Kyla.

She believes her study can play a role in increasing the conviction rate of sexual offenders, which could lead to a reduction in South Africa’s alarmingly high rape statistic. 

“Everyone in South Africa is affected by this horrific crime in some way or another, so the benefits of this would be widespread,” she says.

Solving crimes

Although Kyla will one day pursue further studies, she is ready for the next stage in her life. “I am in the process of applying for jobs and getting ready to dive into the real world. I’ll definitely be pursuing a career working alongside police enforcement to solve criminal cases and convict perpetrators of such crimes. Working for the NYPD in the USA or Scotland Yard in the UK is the ultimate dream job,” she says.

“I chose my field not only because the forensics world absolutely fascinates me, but also because I want to make a difference. I want to play a role in getting justice for those affected by violent crimes. One simple process in a forensic scientist’s everyday routine could be a life changer for a victim of crime,” believes Kyla.

Afrikaans speakers should think differently, says Coenie de Villiers

Do not ask what can be done for your language, but what your language can do for others. With this adaptation of the late John F. Kennedy’s famous words, Coenie de Villiers stressed that the onus for the survival of their language rests with Afrikaans speakers.

According to the television presenter and singer, the real empowerment of Afrikaans does not necessarily take place in parliament. He was the speaker at the DF Malherbe Memorial Lecture, presented in the Equitas Building on the University of the Free State Bloemfontein Campus on 24 May 2016. The lecture by De Villiers, a UFS alumnus, was titled Is Afrikaans plesierig? ’n Aweregse blik.

Government not the only scapegoat
He used Kennedy’s famous phrase, Ask not what your country can do for you, but what you can do for your country, as framework. “I believe that, if we reverse our sights and do not ask what the world can do for Afrikaans, but ask for a change what Afrikaans – and in particular each and every user thereof – can do for others, then we have, in good English terms, ‘a fighting chance’ that Afrikaans will not only survive, but that it will thrive.” He said it would be too easy to just blame the government’s language policy and/or its lack of application for the language’s uncertainties.

Speakers should act correctly
He said the actions of speakers, sometimes motivated by a love for the language, often causes more damage. “It is not the language that should squirm under the microscope. It isn’t Afrikaans that is being tested: it is us, the speakers, writers, thinkers, doers, and tweeters of the language that are being measured.”
De Villiers believes one should stand up for your language without hesitation or fear, but not necessarily in the middle of the road, and never in such a way that you abandon the moral compass of humanity.

Language will live on

He told the audience that Afrikaans speakers should maintain their language every day with the merit, humanity, and respect that they believe the language – and they themselves – deserve. The language will “live on as long as we use it to laugh, and talk, and sing, and do not kill it off with rules and directives.”
