Prof Francis Petersen, UFS Rector and Vice-Chancellor opened the workshop on Monday, 10 February 2020.

Will an enclaved state work in a country like South Africa? How can universities produce graduates who will become engaged citizens, and what is the current status of the ANC and the DA? These were some of the key topics at a workshop on South Africa and Africa: Prevarication at the Precipice, hosted by the Department of Political Studies and Governance at the University of the Free State (UFS). 

The two-day workshop is an annual collaborative discussion platform between the UFS, chaired by Prof Hussein Solomon, the Southern African Centre for Collaboration on Peace and Security, and the Osaka School of International Public Policy

The workshop opened with Prof Francis Petersen, the UFS Rector and Vice-Chancellor who delivered his message from the perspective of higher education. 

He spoke about the importance of universities in South Africa being able to produce graduates who will become active citizens. 

Graduates should fulfill their role in society 

“Universities should be the place where we should educate and engage to let our students and graduates know what society should look like. If we don’t do that transformative thinking among our graduates we are going to perpetuate what society is,” Prof Petersen said. 

“I hope this conference won’t just debate the issues because we already know the answers. I hope this workshop will say what we need to do as active citizens to ensure that we start new building steps. International engagement is also important. As is our engagement with the continent.” 

Helen Zille on the State of South Africa 

Helen Zille, Chairperson of the DA Federal Council presented a talk on the State of South Africa in which she tabled three variables she believes can save the country from the precipice. “There should be three variables which can make a democracy work; a separate state (not a party-ruled state), the rule of law and a culture of accountability,” Zille said. 

Zille tabled the concept of an enclaved state a state which operates independently from party control. “There are increasingly isolated states in SA which are being pushed out of good governance and service delivery. An example of an enclave that functions well is the “justice enclave (Supreme Court of Appeal) in Bloemfontein”. 

She reiterated the importance of active citizenship. However she added that people who are active citizens are usually not the ones elected to office.

The role of active citizenship and the state of the country cannot be discussed in isolation from the state of the ruling ANC and the official opposition, the DA. Prof Dirk Kotze from the Department of Political Studies at Unisa, and Bonolo Selebano, Netwerk 24 political journalist, gave a glimpse into the status of Luthuli House (ANC headquarters in Johannesburg), and the DA. 

“ANC party politics are not unique. They are following a global trend. However, the credibility of the ANC is a big issue,” said Prof Kotze. In the political arena globally, political parties are redefining themselves and it is important for the ANC to figure out where it finds itself. Selebano wasn’t too optimistic about the DA either, saying the party should return to its liberation ideals.

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.
