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.”

Inaugural lecture: Prof. Annette Wilkinson
2008-04-16

A strong plea for a pursuit of “scholarship” in higher education

Prof. Annette Wilkinson of the Centre for Higher Education Studies and Development in the Faculty of the Humanities at the University of the Free State (UFS) made as strong plea for a pursuit of “scholarship” in higher education.

She said in her inaugural lecture that higher education has to deal with changes and demands that necessitate innovative approaches and creative thinking when it concerns effective teaching and learning in a challenging and demanding higher education environment. She referred to a recent research report prepared for the Council for Higher Education (CHE) which spells out the alarming situation regarding attrition rates and graduation output in South African higher education and emphasises factors leading to the situation. These factors include socio-economic conditions and shortcomings in the school and the subsequent under preparedness of a very large proportion of the current student population. However, what is regarded as one of the key factors within the sector’s control is the implementation of strategies for improving graduate output.

She said: “The CHE report expresses concern about academics’ adherence to traditional teaching practices at institutions, which have not changed significantly to make provision for the dramatic increase in diversity since the 1980s.

“Raising the profile of teaching and learning in terms of accountability, recognition and scholarship is essential for successful capacity-building,” she said. “The notion of scholarship, however, brings to the minds of many academics the burden of ‘publish or perish’. In many instances, the pressures to be research-active are draining the value put on teaching. Institutions demand that staff produce research outputs in order to qualify for any of the so-called three Rs – resources, rewards and recognition.

“These have been abundant for research, but scarce when it comes to teaching – with the status of the latter just not on the same level as that of research. From within their demanding teaching environments many lecturers just feel they do not have the time to spend on research because of heavy workloads, that their efforts are under-valued and that they have to strive on the basis of intrinsic rewards.”

She said: “It is an unfortunate situation that educational expertise, in particular on disciplinary level, is not valued, even though in most courses, as in the Programme in Higher Education Studies at the UFS, all applications, whether in assignments, projects or learning material design, are directly applied to the disciplinary context. We work in a challenging environment where the important task of preparing students for tomorrow requires advanced disciplinary together with pedagogical knowledge.”

Prof. Wilkinson argued that a pursuit of the scholarship of teaching and learning holds the potential of not only improving teaching and learning and consequently success rates of students, but also of raising the status of teaching and recognising the immense inputs of lecturers who excel in a very demanding environment. She emphasised that not all teaching staff will progress to the scholarship level or are interested in such an endeavour. She therefore suggested a model in which performance in the area of teaching and learning can be recognised, rewarded and equally valued on three distinct levels, namely the levels of excellence, expertise and scholarship. An important feature of the model is that staff in managerial, administrative and support posts can also be rewarded for their contributions on the different levels for all teaching related work.

Prof. Wilkinson also emphasised the responsibility or rather, accountability, of institutions as a whole, as well as individual staff members, in providing an environment and infrastructure where students can develop to their full potential. She said that in this environment the development of the proficiency of staff members towards the levels of excellence, expertise and scholarship must be regarded as a priority.

“If we want to improve students’ success rates the institution should not be satisfied with the involvement in professional development opportunities by a small minority, but should set it as a requirement for all teaching staff, in particular on entry into the profession and for promotion purposes. An innovative approach towards a system of continuous professional development, valued and sought after, should be considered and built into the institutional performance management system.”

As an example of what can be achieved, Prof. Wilkinson highlighted the work of one of the most successful student support programmes at the UFS, namely the Career Preparation Programme (CPP), implemented fourteen years ago, bringing opportunities to thousands of students without matric exemption. The programme is characterised by dedicated staff, a challenging resource-based approach and foundational courses addressing various forms of under preparedness. Since 1993 3 422 students gained entry into UFS degree programmes after successfully completing the CPP; since 1996 1 014 of these students obtained their degrees, 95 got their honours degrees, 18 their master’s degrees and six successfully completed their studies as medical doctors.

Prof. Wilkinson said: “I believe we have the structures and the potential to become a leading teaching-learning university and region, where excellence, expertise and scholarship are recognised, honoured and rewarded.”
