Hi. I am John. I have anger issues.

Just like John, there are thousands of South Africans with anger issues, often leading to violent crimes such as the more than 21 000 murder cases and 165 000 plus assault cases reported in 2020, according to a study by the South African Police Service and Statistics South Africa.

Aggression can be a great threat to society when it leads to violence. However, it can also be an absolute necessity when it leads to perseverance and a drive towards success and survival. This is according to Zurika Murray, a lecturer in the Department of Genetics at the University of the Free State (UFS), who is doing research on behavioural genetics.

 

Behavioural genetics

She explains behavioural genetics as a study of genetic variation contributing to how an organism interacts with and within its environment. “At the UFS, we focus on human behaviour, and specifically neurotransmitter systems, such as serotonin that may contribute to specific behavioural patterns.”

When one has the right amount of serotonin in your body, it is easier to have stable moods and a sense of well-being.

She says the neurotransmitter (which plays a role in, among others, emotional regulation) acts as a mediator, relaying messages and influencing response to environmental stimuli.  “This system is very adaptable, facilitating our functioning in an ever-changing emotional environment; but when dysfunctional, it can cause quite a number of abnormalities, from anxiety and depression to dysfunctional impulse control and violence. When some individuals are exposed to adverse developmental environments such as abuse and neglect, they can develop aggression and violence.”

“One of our current projects looks specifically at male juvenile delinquency and monoamine neurotransmitter systems (such as serotonin) that may contribute to specific characteristics (such as impulsivity) of delinquency.”

According to Murray, their research is also looking at the genetic variation within specific neurotransmitter genes to see if they could find similarities among individuals with similar developmental backgrounds.  “This neurotransmitter system additionally responds relatively well to physical activity as a management strategy for aggression in some individuals. We are looking at variations in this system that might explain this,” says Murray.

 

Genetic counselling

Apart from the genetic contribution, we also know that the developmental environment plays a very important role. Many people observe anger while growing up – it was thus part of their developmental environment. For them, it is appropriate behaviour in specific situations.

To understand this contribution from the developmental environment, a background in psychology is necessary.  The undergraduate degree in Behavioural Genetics at the UFS has Genetics and Psychology as majors, and this is where the link to genetic counselling comes in.

Murray explains that genetic counselling is a field in medical sciences focusing on helping patients affected by medical conditions to understand the underlying genetics.  For individuals with a family history of genetic conditions (such as specific cancers) or pregnant mothers with foetuses affected by genetic abnormalities (such as Down syndrome), the services of a genetic counsellor are invaluable.  A genetic counsellor will help these individuals understand the cause of the disorder, how it was diagnosed, what the symptoms are, what the progression will look like, if any treatment is available, and what the possible options are (if any) for alternatives.

Genetic counsellors need a strong background in both Genetics and Psychology. To become a registered genetic counsellor, a student completes a BSc degree in Biological Sciences (Behavioural Genetics at the UFS would be ideal).  Thereafter an honours degree in either Genetics or Psychology (though Genetics is preferable).  The student can then apply at either the University of the Witwatersrand or the University of Cape Town for a master’s degree in Genetic Counselling.  This entails two years of study, followed by two years of practical internship. Only after this you will be able to register with the Health Professions Council of South Africa (HPCSA) as a genetic counsellor.

Students studying Behavioural Genetics at the UFS are off to a great start. Murray’s teaching philosophy is to always strive to deliver students who are better than she is. “I can only really do this by sharing my passion for my research. I hope to inspire my students to also always be hungrily curious, to always question, and to find the joy in knowledge and learning.”

In January 1, 2003, the Qwa-Qwa campus of the University of the North (Unin) was incorporated into the University of the Free State (UFS).

FREDERICK FOURIE

IN January 1, 2003, the Qwa-Qwa campus of the University of the North (Unin) was incorporated into the University of the Free State (UFS).

While this is merely the beginning of a long and complex process, it does represent a major milestone in overcoming the apartheid legacy in education, realising the anti-apartheid goal of a single non-racial university serving the Free State.

The incorporation is also part of the minister's broader restructuring of the higher education landscape in South Africa - a process which aims to reshape the ideologically driven legacy of the past.

In contrast to the past educational and social engineering that took place, the current process of incorporating the Qwa-Qwa campus of Unin into the UFS is informed by three fundamentally progressive policy objectives, clearly outlined in the education white paper 3: (A framework for the transformation of higher education):

To meet the demands of social justice to address the social and structural inequalities that characterise higher education.

To address the challenges of globalisation, in particular the role of knowledge and information processing in driving social and economic development.

To ensure that limited resources are effectively and efficiently utilised, given the competing and equally pressing priorities in other social sectors.

Besides informing the way the UFS is managing the current incorporation, these policy objectives have also informed the transformation of the UFS as an institution over the past five years.

In 2001, former president Nelson Mandela lauded the success of the UFS in managing this transformation, by describing the campus as a model of multiculturalism and multilingualism. This was at his acceptance of an honorary doctorate from the UFS.

Indeed our vision for the Qwa-Qwa campus as a branch of the UFS is exactly the same as it is for the main UFS campus - a model of transformation, academic excellence, community engagement and financial sustainability, building on the histories and strengths of both the Qwa-Qwa campus and the UFS (Bloemfontein campus).

Realising this vision will be a giant leap forward in establishing a unified higher education landscape in the Free State.

In more concrete terms, the UFS is working towards this vision by focusing on the following areas of intervention: access and equity; academic renewal; investment in facilities; and sound financial management.

These interventions are being made not to preserve any vestiges of privilege or superiority, but precisely to increase access for students from poor backgrounds and to promote equity and representivity among all staff.

The current growth phase of the UFS has seen student enrolment almost double over the past five years, in particular black students, who now constitute approximately 55 percent of the student population of nearly 18 000 (including off-campus and online students).

But it has not just been a numbers game. Our approach has been to ensure access with success.

Our admissions policy, coupled with the academic support and "career preparation" programmes we offer, have resulted in significant successes for students who otherwise would not have been allowed to study at a university.

This will be continued at Qwa-Qwa as well.

Our academic offerings too have undergone dramatic change. We have become the first university in the country to offer a degree programme based on the recognition of prior learning (RPL).

This is not just a matter of academic renewal but of access as well, especially for working adults in our country who were previously denied a university education.

As for the sound financial management of the UFS (including the Qwa-Qwa campus), this is being done not for the sake of saving a few rands and cents, but for the greater value to our society that comes from having sustainable institutions.

It is sustainable universities that can make long-term investments to fund employment equity, provide information technology for students, upgrade laboratories, construct new buildings, develop research capacity, and provide a safe environment for students and staff, as is happening now at the UFS.

As a result of such management, a practical benefit for prospective students at the Qwa-Qwa campus of the UFS will be lower academic fees in some cases compared with the Unin fees.

As is the case with all these processes, there are concerns from staff and students at Qwa-Qwa and the broader community of the region that the Qwa-Qwa campus serves.

To get the campus viable and to ensure its continuation in the short term, tough choices had to be made by the minister of education regarding which programmes to offer and fund.

But we have been encouraged by the community's understanding that these concerns can be addresed over time as the campus becomes financially viable.

Meetings between the top mangement of the UFS and community representatives, staff and students at Qwa-Qwa have laid the basis for building a climate of trust in such a complex process.

We should not be captives of the past divisions but build this new unified higher education landscape that can meet our country's developmental needs.

It should be a higher education landscape that is based on broadening access, promoting equity and social justice, developing academic excellence, and the effective and efficient management of scarce resources. This should be our common common objective.
