Global Citizenship
Distinguished speakers and scholars gathered at the University of the Free State to discuss global citizenship and the transformative role of African higher education in celebration of Africa Day.

The University of the Free State (UFS) recently hosted a compelling event at its Bloemfontein Campus in celebration of Africa Day. Under the theme “World Citizenship and African Higher Education: Preparing Students for a Connected World”, the gathering, organised by the Office for International Affairs, brought together distinguished speakers and scholars to explore the significance of Africa Day and the pivotal role of African institutions of higher learning in shaping a global mindset.

In his opening address, Prof Francis Petersen, Vice-Chancellor and Principal of the UFS, emphasised the importance of commemorating Africa Day as a means to honour the continent's history, celebrate its diversity, and reaffirm commitments to unity, peace, and progress in Africa. “Events of this nature remind us that Africa is rising and increasingly claiming its rightful place as a thought and leadership influencer in the global community of nations. How we, as the UFS, embrace this as an opportunity for innovation and impact is of critical importance to our institutional vision, which we call Vision 130, setting out our collective intent to the year 2034, when the university will mark the 130th anniversary of its founding,” he added.

Addressing inequality and colonial legacies

A panel discussion featuring prominent speakers delved into critical issues affecting African society and higher education. Advocate Thando Gumede, a respected human rights and feminist activist, passionately advocated for substantive equality and the dismantling of systemic barriers to empower black women in society, with a particular focus on academic institutions. Gumede emphasised the persistent issues facing African women and girls, particularly black women, in the economy and leadership roles. “It’s now 2024, and yet a black government has purposefully and intentionally failed to meaningfully address the laws, systems, and colonial ideologies that ultimately led to the socioeconomic and political paralysis and violation of African women and girls today, especially black women within the economy and roles of leadership,” she asserted.

She further elaborated on the metaphor of tiptoeing around a house, symbolising the cautious and ineffective efforts to address these deep-seated issues. Advocate Gumede’s call to action was clear: "We have been tiptoeing in this house for 30 years, not wanting to bump the nice transparent vases around the house. We have been silently tiptoeing around this house so as to not wake up the masters. We have been unable to breathe in this house because we have been giving excessive amounts of oxygen to those who don't need it as much as we do. And so, what I'm trying to say is that unless we are willing to tear the entire house down and smash the foundation that it once stood on, there ain’t nothing going to change. Folks, we need to destroy the house and go build something new somewhere else."

Decolonising academic discourse and promoting inclusivity

Other panelists included Prof Itumeleng Mosala, an academic specialising in theology and religious studies, who passionately highlighted the need to decolonise theological discourse and challenge Eurocentric narratives for a more inclusive academic environment. Additionally, Prof Vasu Reddy, Vice-Chancellor: Research and Internationalisation of the UFS, stressed the value of embracing diverse perspectives and knowledge systems to cultivate critical thinking and intercultural understanding among students.

Promoting social justice through higher education

Dr Phethiwe Matutu, CEO of Universities South Africa (USAf), spoke about the pivotal role of higher education institutions in promoting social justice through global engagement and addressing historical injustices to build a more equitable society. “Success in higher education hinges on multiple components, including access, resources, and the integration of indigenous knowledge systems. Embracing indigenous knowledge is vital not only for cultural affirmation but also for global advancement, with numerous universities and organisations making significant strides in this area.”

“Pedagogies that promote social justice, such as peer learning and reflective teaching, are essential. These methods validate students' knowledge and encourage comprehensive learning. The Ubuntu pedagogy, which emphasises care, collaboration, and language, is particularly affirming and relevant in advancing education,” she added.

Towards equity and renewal

Three recommendations were proposed for consideration: undoing the residue of colonial leadership ethos, leveraging African knowledge systems in education, and continuously questioning and reflecting on practices to ensure alignment with values and genuine progress.As the event concluded, Prof Petersen urged attendees to reflect on the insights shared and consider their roles in driving positive change within their communities and institutions. The UFS Africa Day event served as a platform for robust discourse on advancing global citizenship and African higher education, reaffirming the institution's commitment to excellence, inclusivity, and the pursuit of knowledge for societal transformation.

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.
