The UFS Centre for Gender and Africa Studies, in conjunction with the South African Institute of Race Relations (IRR), recently hosted the fifth instalment of the Africa Dialogue Series. The webinar series – established by Prof Hussein Solomon – has rapidly grown in stature. The latest discussion on the SA Election Aftermath: Economic, Security and Political Considerations drew high-profile international attendance that included several ambassadors, military attachés, and representatives of security communities.

“Part of the success of the Africa Dialogue Series,” Prof Solomon says, “is that we include a variety of speakers in each discussion. This ensures that the conversation remains relevant.” 

Economic challenges amid coalition governments

Prof Philippe Burger, Dean of the UFS Faculty of Economic and Management Sciences, opened the discussion by highlighting the complexities of coalition governments in South Africa – especially given the country’s lack of experience with such political arrangements. Prof Burger further pointed out the difficulty of managing coalitions amid economic stagnation, high unemployment, poverty, and mounting debt. At the time, Prof Burger forecast that a coalition with the Democratic Alliance (DA) might push for pro-market reforms, but that such an agreement could still suffer from instability due to ideological differences. Prof Burger predicted a ‘rocky five years’ ahead for any coalition government.

A shift in security strategy

Transitioning to security matters, Eeben Barlow, Chairman and CEO of Executive Outcomes, stressed the paramount importance of a robust national security strategy for the new government's stability and South Africa's interests. He advocated for a comprehensive reassessment of the current strategy, urging a shift from reactive policies to a proactive, pre-emptive approach. Barlow underscored the need to align intelligence, law enforcement, and military efforts within this revamped strategy through proper structuring, training, and resourcing. He warned that without comprehensive security planning and decisive implementation, South Africa risks further instability, economic decline, and international reputational damage.

Political fragmentation

Next, Terence Corrigan, Project and Publication Manager at the IRR, offered a sobering analysis of the election results. He noted the severe weakening of the previously dominant ANC, which no longer serves as the nation's ‘moral voice’. Despite this, the opposition failed to capitalise decisively, with the DA potentially reaching its voter ceiling. Corrigan expressed concern over the rise of anti-constitutional parties such as the EFF and MK, which exploit public grievances and pose a ‘populist challenge’ to democratic institutions. He predicted increased political fragmentation and ‘fractious politics’ as South Africa navigates this political landscape.

Legislative gridlock and electoral reform

Adding to the discussion of political challenges, Marius Roodt, Deputy Editor of Daily Friend, noted the worrying decline in voter turnout, and reiterated the concerns regarding South Africa’s fragmented politics. Roodt warned that this fragmentation could lead to legislative gridlocks from minority governments or unstable coalitions unable to pass laws. To address these issues, he proposed electoral reforms, including minimum vote share thresholds, extended time frames for forming governments, binding coalition agreements, and restrictions on motions of no confidence. While some view gridlock as a check against radical policies, Roodt acknowledged that an inability to pass the necessary laws could hamper investment.

Broader political implications

Concluding the presentations, Sanet Solomon, a political analyst and lecturer at UNISA, provided an overarching analysis of South Africa's political landscape post-elections. She called attention to the historic significance of three decades of democracy and fluctuating voter turnout influenced by various challenges and achievements. Solomon emphasised the critical nature of policy alignment in coalitions, particularly the ANC's collaboration with the DA. She also discussed the complexities of maintaining macroeconomic stability, the urgent need for rule of law and anti-corruption measures, and the importance of strategic, cohesive policy making in the nation's future.

The webinar underscored the multifaceted challenges facing South Africa's new coalition government, highlighting the need for strategic economic, security, and political planning to navigate the uncertain road ahead.

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.
