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.”

Statement on protest at the UFS
2005-03-04

Following a protest by student and non-student organisations today, the management of the University of the Free State (UFS) would like to place the following facts on record:

1. There is a well-documented process underway to further transform the UFS. At the official opening of the UFS on 4 February 2005 , the Rector and Vice-chancellor, Prof Frederick Fourie, announced that the UFS would draft a comprehensive Transformation Plan to guide the next phase of transformation at the institution.

The UFS appeals to student formations, staff associations, trade unions and other role-players to make a constructive input into this Transformation Plan.

The UFS management has been - and always will be - willing to engage with role-players and is prepared to do so even after today’s protest.

2. There is thus no regulation or policy prescription which separates students in hostels according to race.

The reality is that students exercise their freedom of choice as to which hostel they wish to be placed in. This was agreed upon by black and white students in 1997/8.

However, the unintended consequence and practice of this hostel placement policy has been that students themselves have tended to choose to stay in hostels which have over time become black hostels and white hostels.

This is a matter of concern for the management of the UFS as such a situation does not promote interaction across language, cultural and socio-economic groupings of students.

This matter is receiving attention and an intensive consultative process, which will include students, will be launched to review this policy.

The management is convinced that such interaction will enhance the learning experience of all students and sensitise them to the reality of a multicultural South Africa and a multicultural world.

3. No student organisation has been banned from operating at any of the three campuses of the UFS.

In the past few weeks, SASCO, the Young Communist League and the ANC Youth League (ANCYL) have held meetings on all three campuses, namely the Qwaqwa campus, the Vista campus and the main campus.

There are also regular interactions between top management and the leadership of SASCO and the ANCYL on campus.

In fact, the UFS upholds the right of students and staff to associate freely and to organise themselves as they see fit.

The UFS also upholds the rights of staff and students to engage in legal and peaceful protests.

The management however remains committed to discussing issues that affect staff and students in a constructive manner and appeals to student organisations in this case to engage with management.

4. The issues of registration, fees, debt and financial aid are continually monitored, and interventions to assist students are made regularly. To assist as far as possible those academically deserving students who face financial difficulties, the UFS management has put in place a structure called the Monitoring committee that includes management and student representatives.

The purpose of the Monitoring Committee is to review the cases of individual students to determine how best they can be assisted.

This applies to the Qwaqwa campus, the Vista campus and the main campus.

It is generally the case that students who perform academically will not have any difficulty in obtaining financial assistance. However, according to the requirements of National Student Financial Scheme, students who perform poorly will have difficulty in obtaining such assistance.

5. With regard to student governance, the process to institute an inclusive Central Student Representative Council (SRC), on which all three campuses will be equitably represented, was launched in July 2004, and a preliminary constitution has just been drafted. At the same time an inclusive process to review certain elements of the constitution of the main campus SRC was initiated at the end of 2004. This process, which includes all relevant student organisations and structures, is planned to produce an outcome within the next couple of months.

6. There is no policy at the UFS that is based on racism or that discriminates on the basis of the race of students and staff.

As part of the building of a new institutional culture within the broader transformation process, the UFS management is determined to eradicate all elements of racism that may occur on its campuses, and has already instituted inclusive forums on campus to discuss the issue of values and principles for a non-racial university.
