In a world increasingly defined by the stark contrasts of power and vulnerability, the concept of democracy often reveals itself as a double-edged sword. For the children of struggle – those who have grown up amid the chaos of inequality and conflict – democracy can feel like a distant promise, an ideal often outmanned by the realities they face. The deception of hope lingers in the air as aspirations clash with systemic barriers, leaving many to navigate a landscape where a harsh daily existence obscures the principles of freedom and justice. This exploration seeks to uncover the intricate dynamics between hope and disillusionment, shedding light on the lived experiences of those who yearn for a brighter future yet grapple with the weight of unfulfilled promises.
This was the essence of the public lecture titled Outmanned by Democracy: Children of Struggle, Deception, and Hope, presented by Prof Allan Boesak, a theologian and political activist, on the Bloemfontein Campus.
Prof Boesak confronted the continuous socio-economic challenges faced by South Africa and other nations, including racism, narrow ethnic nationalism, and the revival of tribalism. He emphasised the role of churches in tackling these issues. “The responsibility of churches is to articulate what politicians are often afraid to say,” he stated. “Put your ideologies into practice and leverage your power as ministers of the Word to shape the future and reclaim the dignity of your people. This is where unity transcends colour and stature. Consider the various roles that churches could play in reconciling communities, as seen in the Gaza crisis.”
During his visit to the UFS Faculty of Theology and Religion, Prof Boesak also launched a four-volume set titled The Fire, The River and the Scorched Earth: Fifty Years of Black Theology Through the Lens of Allan Boesak. The first three volumes include his lectures and responses from various theologians, while the fourth contains his sermons. This body of work aims to document, critique, and celebrate the contributions of black theology, highlighting its role in the struggle for justice and liberation and underscoring Prof Boesak’s unwavering commitment to freedom, liberation, and democracy.
In a time when hope and disillusionment coexist, Prof Boesak’s insights remind us of the transformative power of faith and activism in the continuing fight for a more equitable world
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.
