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.”

Qwaqwa Campus opens: Prof. PA Mbati's speech
2005-01-22

Official welcome speech by Prof. PA Mbati for 2005 first year students held on Saturday 22nd January 2005. Program Director, The Chief Director Operations Rev. Kiepi Jaftha, Dean of Students Dr. Natie Luyt, Program Head of the Faculty of Humanities, Dr. Elias Malete, Program Head of Faculty of Natural and Agricultural Sciences, Prof. Riaan Luyt, Acting Program Head of the Faculty of Economics and Management Sciences Prof. Andries Venter, Deputy Director Student Affairs Mr. Teboho Manchu, Coordinator Finance: Mrs. Elizabeth Nchapi, Senior Librarian Mr. Stoffel Kok, Senior Magistrate Mr Saul Mohosho, SRC President Mr. Tello Motloung, members of staff, invited guests, parents, guardians, my dear students, ladies and gentlemen.

It is indeed my pleasure to welcome you to the official welcoming ceremony of the UFS-Qwaqwa Campus 2005 first year students. Our Rector and Vice Chancellor Professor Frederick has requested me to pass to you his warmest wishes and regards on this special occasion. I am confident that the orientation exercise in which you have participated has achieved the desired effect of introducing you to your new way of life here on campus, and that you are now sufficiently prepared to get on with the rigors of being a student at this University.

Following the restructuring of the higher education landscape, the Qwaqwa campus was incorporated into the University of the Free State with effect from January 1 2003 . As a consequence, Management was faced with a whole complex series of challenges including, primarily making the campus financially viable, but also ensuring that it remains relevant in it’s core business as a satellite campus of the University of the Free State in terms of its teaching, learning, research and community service responsibilities.

A whole series of strategic planning workshops were conducted last year with both internal and external stakeholders. Various important strategic objectives were flagged out, and the next level of consultation will take place soon. I know that there is a lot of eagerness, sometimes to the level of impatience to see this process completed as quickly as possible. But again on the other hand, due to the far reaching consequences of any hasty decisions, plus the need for a carefully planned process, we need to be a little more patient before the implementation of the strategic objectives is implemented. You will be kept informed as this important and critical aspect in the evolution of our campus takes place.

As a response to the need for a more effective governance model on the Qwaqwa campus, a review of the governance structure was completed towards the end of 2004 and will soon serve before the Executive of the Executive Management for approval.

Due to the importance that top management attaches to the development of an effective governance on the Qwaqwa campus, the process was facilitated by an internationally acclaimed consultant. Again the contents of the revised governance model will be made known to the campus and the broader community once it is approved.

I am glad to report that in recognition of the need to improve the infrastructure on campus to provide a conducive learning atmosphere to our students, a total of 8.2 million rands was made available towards the end of 2004 for recapitalization of specifically our student residences and lecture venues. The first phase of the residence renovation is completed and residences C, D and E have now been officially handed over to the University by the Contractor. Among the features of the renovated residences is that they will now computer rooms, kitchenettes for cooking, and a redesigned TV room. The rooms have even been fitted with heaters. Our challenge will now be to maintain our newly acquired facilities and to ensure that they do not again deteriorate to an un-acceptable level. The second phase of renovation will start soon.

As indicated in my address during the orientation week, our obligation to you as a campus is to offer you quality training to the best of our ability, and to disseminate this knowledge to you within a conducive atmosphere worthy of good learning. On the other hand, our students have to take advantage of this opportunity to acquire the necessary skills and training in the various academic programs that we offer on campus.

We have a very simple agenda on this campus – our vision is to continuously strive to build and develop the Qwaqwa campus of University of the Free State into a truly quality institution of higher learning in our country. To develop a tradition and culture in which we are proud of who we are, and constantly and tirelessly working towards excellence in our academic programs, and other non-academic but core and important aspects in your growth and development such as sport and community service. To nurture young conscientious citizens who are aware of their duties and responsibilities. Ultimately to produce hard working young people who fully exploit their potentials, and who will serve this country with diligence when unleashed into the real world in effectively managing their roles and responsibilities in society, whether in private or government civil service.

I would like to encourage that the various stake holders of this campus, the students, academic, administrative and support staff, and our broader community, to work together in harmony for the well being of our campus. For this campus to continue to be relevant in the environment that we find ourselves, there is a need for continuous engagement of its various stake holders, and genuinely listening to each other. We must continuously and regularly keep our feelers on alert in order that we can remain relevant.

I am particularly inviting our parents and guardians, the alumni of this campus, and leaders from our community to join hands with us in seeking solutions to the various challenges that we continue to face on campus. I am open for frank and honest discourse on the best way forward for our campus.

The University of the Free State is committed in making tertiary education accessible to as many students as possible. In this regard, students who do not have the required ‘M’ score to gain entry into main stream classes are given an opportunity to study in the highly successful ‘bridging program’ in which learners are integrated with main stream students but with fewer courses to tackle in order to ensure success. This is done on the premise that such students have the potential to pursue a degree course, and that therefore within a well structured program, they can make a success of their lives.

The University is conscious of the fact that in many instances several academically deserving students fail to be admitted into university due to financial reasons. For students who are academically deserving but who because of reasons of poverty cannot pay the requisite fees, the university is able to assist such students through the National Financial Aid Scheme – commonly known as NSFAS, and University Merit Awards. Other incentives such as Sports bursaries are also available.

Please remember that it is important to balance your life on campus and the phrase ‘a healthy mind in a healthy body’ aptly describes this statement. Ensure that you participate in sport and cultural activities of this campus so that you can develop and strengthen the various God-given talents that you have been blessed with.

A second major ingredient for your success on campus is discipline and respect for rules, policies and procedures that govern the University of the Free State , and respect for your fellow students. Good discipline is a major contributory factor to success in life, and more so in your formative academic life at University. This means for example that you must attend all your lectures, complete your assignments on-time and visit the library frequently. Please manage your time wisely and responsibly. Remember that as a university student, you are basically the master and architect of your own destiny.

Think very carefully when you are confronted with difficult situations, be they negative peer pressure, or temptations to indulge in intoxicating drugs, and make the right choice.

The University has well trained personnel including a social worker, a psychologist and counselor, and members of the student affairs division under the leadership of Mr. Teboho Manchu, Deputy Director Student Affairs, who are available to assist whenever you require their help.

Today is also a special day because we have officially inaugurated the SRC President and the rest of the SRC leadership. I am sure that you all join me in congratulating the SRC for being elected to their leadership roles for 2005. Mr. SRC president and your team, please remember that you now have a huge responsibility in carrying out the aspirations of the student body on campus. I want to wish you luck and success as you champion the rights of your constituents, which I believe and trust will be compatible with management’s expectations with regard to quality teaching and learning on campus. As you are aware, Management values the input that the student leadership makes in the operational management of the affairs of this campus, and we look forward to a cordial, non-confrontational working relationship with a view of rendering un-paralleled service on campus.

Mr. Program Director, allow me to wish everyone here a successful and prosperous year. May the good Lord give us the strength and courage to overcome any obstacle that may be placed in our way in the course of our work in 2005.
