South Africans are sick and tired of corruption. They are angry, frustrated and despondent. And they have every reason to be. South Africa has many problems: crime, unemployment, poverty, gender-based violence, inequality, low economic growth and now – in common with many other countries – COVID-19. The list goes on and on. What makes corruption the biggest threat among all these is that it cuts across all of them and impacts on their gravity in different ways. 

The South African Constitution envisages a society based on democratic values, social justice and fundamental human rights. The way things are going, that society is never likely to happen. That is because corruption has been, and continues to be, the greatest threat to any possibility of realising that constitutional dream. In South Africa, like everywhere else where corruption is rampant, it occurs both in the public and private sectors, where it affects democracy and human rights by deteriorating institutions and diminishing public trust in government. It impairs the ability of government to fulfil its obligations and ensure accountability in the delivery of economic and social services like healthcare, education, clean water, housing, and social security. This is because corruption diverts funds into private pockets – which impedes delivery of services – thereby perpetuating poverty, inequality, injustice and unfairness. The problem is aggravated when government is the main culprit. “Government” here, of course, refers to the dictionary meaning of the term, namely, “the group of people with the authority to govern a country or state”.

Corruption existed in ancient Egypt, China and Greece

There are those who argue that corruption is as old as mankind and, therefore, it is here to stay. Indeed, corruption is known to have existed in ancient Egypt, ancient China and ancient Greece. In Robert Bolt’s 16th Century play A Man for All Seasons, Richard Rich’s opening remark is “But every man has his price.” In the 1836 play The Government Inspector, Nikolai Gogol cleverly satirised the human greed, stupidity and extensive political corruption in Imperial Russia at the time. And in a recent article in The Conversation (28 August 2020), Steven Friedman wonders why South Africans express shock at corruption when “it is perhaps the country’s oldest tradition.” He locates the advent of corruption in South Africa at the arrival of Jan van Riebeeck in 1652, through to the ensuing colonialism and apartheid. He argues that in reality, “corruption has been a constant feature of South African political life for much of the past 350 years. It is deeply embedded and it will take a concerted effort, over years, not days, to defeat it”. 

Agreed, but does it have to be that way? At the time of Jan van Riebeeck and during the 350 years of colonialism and apartheid, we did not have the legal framework that we have now. Here is a brief overview of that framework.

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.
