student dialogue
Dialogues presented by the Office for International Affairs provide a safe space for people to voice their opinions, to learn, and to engage. Here are, from the left: Montsi Ramonaheng, third-year BSc student majoring in Biochemistry and Genetics; Lebohang Lesenyeno, third-year LLB student; Motsaathebe Serekoane, Lecturer in Anthropology; and Bulelwa Moikwatlhai from the Office for International Affairs.

Will the creation of one African country solve the problem of xenophobia? 

This was the question raised at a recent dialogue session on the University of the Free State Bloemfontein Campus.

Most attendees believed the concept of ‘one Africa’ implied that only one language and one dominant culture would be needed – resulting in the spirit of multiculturalism ceasing to exist. When one speaks of a united Africa, it means that the continent recognises the diversity of its cultures and embraces these diversities. It was concluded that one Africa was not a solution to ending xenophobia.

Awareness of xenophobia from a human rights perspective

The Office for International Affairs hosted the two-dialogue series aimed at addressing an array of social issues such as xenophobia, cultural appropriation, and xenocentrism. They wanted to demonstrate the influence these issues have – not only on the mindsets of individuals, but also on how it can contribute towards the development of an unjust society devoid of embracing difference.

The first session was titled: Burn the Phobia, with the theme: ‘We are all foreigners somewhere’. The aim of this dialogue was to create awareness of xenophobia from a human rights perspective. 

Recently, a second dialogue session was presented, with the theme ‘Appropriation vs Xenocentrism’. According to Bulelwa Moikwatlhai, Officer in the Office for International Affairs, the purpose of this session was to encourage people to appreciate their own cultures and to respect other peoples’ cultures.

“We wanted to critically discuss cultural appropriation versus xenocentrism in an attempt to find a human response that is inclusive in nature,” says Moikwatlhai.

Direct outflow of UFS Integrated Transformation Plan

The lecture was presented by Motsaathebe Serekoane, Lecturer in the Department of Anthropology at the UFS, who urged attendees to always keep it authentic. He also stated that, as boundaries between the North and the South collapsed and knowledge flowed in and out, knowledge from the South was not taken seriously. 

“We lost ourselves within what happened in the North. We want to be appropriate and we want what they have, because it is more beautiful than what we have. We need to find something in Africa that will define us as African,” he says. 

These dialogues are a build-up to the International Cultural Diversity Festival that will take place at the Thakaneng Bridge on 13 September 2019 from 12:00 to 14:00.

The dialogue is a direct outflow of the university’s Integrated Transformation Plan. “We strive to cultivate a culture where everyone feels welcome and comfortable. We want to create common ground for international and South African students to get together and to collaboratively discuss issues from both parties in order to find innovative solutions to student challenges,” indicates Moikwatlhai.

Much of what is learnt in these sessions is used for reflection in order to improve the overall student experience. According to Miokwatlhai, it is essential to ensure that all processes related to students are structured to be socially just and inclusive. 

“As an institution of higher learning, we need to continuously create such platforms so that we have rich engagements about pertinent issues that affect the UFS community, and find human solutions to overcome barriers,” she concludes.

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.
