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.

Salary adjustment of 7,5%

The University of the Free State’s (UFS) management and trade unions have agreed on a general salary adjustment of 7,5% for 2012.
 
The negotiating parties agreed that adjustments could vary proportionally from a minimum of 7,3% to a maximum of 8,5%, depending on the government subsidy and the model forecasts.
 
The service benefits of staff will be adjusted to 9,82% for 2012. This is according to the estimated government subsidy that will be received in 2012.
 

UVPERSU and NEHAWU sign
 
The agreement was signed (today) Tuesday 8 November 2011 by representatives of the university’s senior leadership and the trade unions UVPERSU and NEHAWU.
 

R2 500 bonus
 
An additional once-off, non-pensionable bonus of R2 500 will also be paid to staff with their December 2011 salary payment. The bonus will be paid to all staff members who were in the employment of the university on UFS conditions of service on 31 December 2011 and who assumed duties before 1 October 2011. The bonus is payable in recognition of the role played by staff during the year to promote the UFS as a university of excellence and as confirmation of the role and effectiveness of the remuneration model.
 
It is the intention to pass the maximum benefit possible on to staff without exceeding the limits of financial sustainability of the institution. For this reason, the negotiating parties reaffirmed their commitment to the Multiple-year, Income-related Remuneration Improvement Model used as a framework for negotiations. The model and its applications are unique and have as a point of departure that the UFS must be and remains financially sustainable. 
 
 
Capacity building and structural adjustments
 
Agreement was reached that 1,54% will be allocated for growth in capacity building to ensure that provision is made for the growth of the UFS over the last few years. A further 0,78% will be allocated to structural adjustments.
 
Agreement about additional matters such as funeral loans was also reached.
 
“The Mutual Forum is particularly pleased that a general salary adjustment of 7,5 % could be negotiated for 2012. Taken into account the world financial downturn, marked cuts in university subsidies and the growth of the university, this is a remarkable achievement,” says Prof. Johan Grobbelaar, Chairperson of the Mutual Negotiation Forum. 
 

Increase for Professors, Deputy and Assistant Directors
 
According to Prof. Grobbelaar the Mutual Forum is also pleased that Professors and Deputy and Assistant Directors will benefit from the structural adjustments. These increases will align the positions with the median of the higher education market. The 1,54% allocated for growth will ensure that appointments can be made where the needs are the highest. The special year-end bonus of R2 500 is an early Christmas gift and implies that the employees in lower salary categories receive an effective increase of almost 9,5 %.
 
“The UFS is in a unique position when it comes to salary negotiations, because the funding model developed more than a decade ago, has stood the test of time and ensured that the staff receive the maximum possible benefits. Of particular note is the fact that the two majority unions (UVPERSU and NEHAWU) work together. The mutual trust between the unions and management is an example of how large organisations can function to reach specific goals and staff harmony,” says Prof. Grobbelaar. 

The implementation date for the salary adjustment is 1 January 2012. The adjustment will be calculated on the total remuneration package.
