The recent events in Senekal in the Eastern Free State have, for the umpteenth time, thrust the related issues of farm murders, racial tension, violent crime, and the responses of political leaders to these issues on the national agenda. The latest outrage was sparked by the murder of farm manager Brendin Horner. On Tuesday 6 October 2020, demonstrators – mostly white farmers – embarked on a violent protest at the Senekal Magistrates’ Court, following the appearance of two suspects for allegedly murdering Mr Horner. According to reports, a gunshot was fired, and a police vehicle was set on fire. 

In response, EFF leader Julius Malema called on his ‘ground forces’ to attend the Senekal trial of the murder accused, scheduled for 16 October 2020, to ‘defend’ state property and democracy. This response has generated a polarised reaction from the public, with some supporting this call, while others criticised Malema for inciting violence and racial division.

This drama is playing out while the country is still reeling from continuing incidents of gender-based violence and violence against children.

Violence in South Africa

This begs the question: Do we have a culture of violence in South Africa?

The concept of culture is often used (and misused) to refer to a range of different things. For some, culture refers to the observable distinctive traits of a particular group or collective, such as dress, food, or technology. For others, it refers to more abstract traits such as language, beliefs, or customs and traditions. For still others, culture refers to an appreciation for human expression in the form of art and music. Culture is all of these things, but it is also more than this. 

Anthropologically, culture is a central concept that helps us to make sense of human social dynamics and behaviour across all times and locations. As such, culture is seen as a complex system that both shapes, and is shaped by, humans within specific contexts. Culture thus has three key characteristics that concern us here. First, culture is shared. Second, culture is learned. Third, culture is symbolic.  

The question of whether or not we are in a culture of violence in South Africa raises further questions about whether we can, or should, speak of a culture of violence in the first place. What can we observe if we analyse this concept in relation to the three characteristics of culture outlined above?

Is violence shared?

As a country, we indeed share a history of violence. We share a history of multiple levels of violence, including structural, political, economic, social, and even cultural violence. We also share in the mass media consumption of violence, be it through movies, television, or even news reports of violence in our society. 

Is violence learned?

A culture survives over time because it is learned by successive generations. Values, beliefs, customs, practices, language, and many other symbols of culture are transferred from generation to generation through enculturation or socialisation. Experiences of violence, whether as perpetrators or victims or both, are inherited by successive generations. This is why we see many examples of history repeating itself in, for example, violent protests, or excessive force by police, or perceived violence inciting rhetoric. None of these are new, as there are various examples throughout our history as a country.   

Does violence have any symbolic significance?

What does violence mean in South African society? What is its symbolic value? Violence has become like a language. It is a form of communicating or expressing a range of negative emotions and attitudes, including anger, frustration, fear, anxiety, intolerance, and disrespect for basic human rights. It is still perceived by many as a valid symbol of resistance and may be justified on this basis. How often do we hear people involved in violent protests saying that “violence is the only language the government understands!” Thus, violence certainly has symbolic value in the South African historical and contemporary context. 

From the above, it could well be argued that, in terms of the three characteristics of culture, there indeed exists a culture of violence in South Africa. 

Addressing the culture of violence 

But what can we do about it?

Perhaps the best way to address the culture of violence, is to start with the successive generations. In any society, if you want to change the culture, you need to start with the youth. Cultural values are more easily shaped and adopted by the youth than by older generations who tend to be more rooted and set in their ways of thinking and behaving. If we want to change the culture of violence, we need to start changing the values, attitudes, and traits that may engender violence among the youth. These changing values then need to be enculturated among the youth in the hope that it will be internalised sufficiently to promote new ways of thinking and behaving.

How do we achieve this? By demonstrating proper leadership and by being the examples that we want our youth to become. We cannot expect to dismantle the culture of violence if we have leaders who, whether intentional or not, are perceived to be promoting the very values that encourage violence and anarchy. We need to demonstrate a willingness to use more productive and constructive ways to resolve differences or conflict, other than resorting to destruction of property or harming others. 

Lastly, it is imperative that we address the structural violence of an enduring social and economic system that continues to victimise and marginalise many. Culture and environment are interlinked. In order to change the culture of violence, we need to change the environment of violence.

Mathematical methods used to detect and classify breast cancer masses

Examples of Acho’s breast mass
segmentation identification

Breast cancer is the leading cause of female mortality in developing countries. According to the World Health Organization (WHO), the low survival rates in developing countries are mainly due to the lack of early detection and adequate diagnosis programs.

Seeing the picture more clearly

Susan Acho from the University of the Free State’s Department of Medical Physics, breast cancer research focuses on using mathematical methods to delineate and classify breast masses. Advancements in medical research have led to remarkable progress in breast cancer detection, however, according to Acho, the methods of diagnosis currently available commercially, lack a detailed finesse in accurately identifying the boundaries of breast mass lesions.

Inspiration drawn from pioneer

Drawing inspiration from the Mammography Computer Aided Diagnosis Development and Implementation (CAADI) project, which was the brainchild Prof William Rae, Head of the department of Medical Physics, Acho’s MMedSc thesis titled ‘Segmentation and Quantitative Characterisation of Breast Masses Imaged using Digital Mammography’ investigates classical segmentation algorithms, texture features and classification of breast masses in mammography. It is a rare research topic in South Africa.

 Characterisation of breast masses, involves delineating and analysing the breast mass region on a mammogram in order to determine its shape, margin and texture composition. Computer-aided diagnosis (CAD) program detects the outline of the mass lesion, and uses this information together with its texture features to determine the clinical traits of the mass. CAD programs mark suspicious areas for second look or areas on a mammogram that the radiologist might have overlooked. It can act as an independent double reader of a mammogram in institutions where there is a shortage of trained mammogram readers. 

Light at the end of the tunnel

Breast cancer is one of the most common malignancies among females in South Africa. “The challenge is being able to apply these mathematical methods in the medical field to help find solutions to specific medical problems, and that’s what I hope my research will do,” she says.

By using mathematics, physics and digital imaging to understand breast masses on mammograms, her research bridges the gap between these fields to provide algorithms which are applicable in medical image interpretation.
