During the past eight months, the University of the Free State Academy for Multilingualism has reached remarkable milestones. The Academy for Multilingualism was born from the UFS Language Policy (2016) and was approved by Senate in November 2020.

 

Letting languages grow

Multilingualism at the UFS entails the use of English as the primary medium of instruction, with Afrikaans, Sesotho, and isiZulu used selectively in tutorials to support the achievement of greater levels of academic literacy and understanding of the epistemology of the discipline, mostly among undergraduate students. “Accordingly, the academy’s drivers are to develop Sesotho and Isizulu as academic languages, encourage multilingualism in teaching and learning and as a social asset, and to develop English as a language of instruction,” says Dr Peet van Aardt, Custodian of the Academy for Multilingualism.

 

Developing Sesotho and Isizulu as academic languages

Academic word lists from seven departments are in the process of being translated, in conjunction with the Unit of Lexicography, to create glossaries. The team at South African Sign Languages will add videos to these glossaries to provide unique and inclusive content in the realm of multilingualism.

In April 2021, the academy – in collaboration with the TK Mopeli Library on the Qwaqwa Campus – hosted the launch of an English and Sesotho book on the campus. This work, Meriana ya Dimela tsa Basotho Medicinal Plants, was authored by Prof Rodney Moffett, honorary Research Fellow on the Qwaqwa Campus.

 

Multilingualism in teaching and learning

To assist students in overcoming the language barrier caused by English as medium of instruction, the academy is working with the Centre for Teaching and Learning’s A_STEP programme to pilot the use of translanguaging in tutor sessions. It is currently done in Law and Geography on the Bloemfontein Campus, and in Academic Literacy on the Qwaqwa Campus.

Voice-over translations of English lessons in the Faculties of Theology and Religion into Afrikaans and Sesotho paved the way for the academy to proceed with this practice in other subjects. They have been able to start with the Departments of Political Studies and Governance (Afrikaans, Sesotho, isiZulu) and Criminology (Sesotho).

 

English as a language of instruction

The university’s Academic Literacy and Language Development (ALLD) unit has also launched their English Academic Literacy courses for the Faculties of Law, Natural and Agricultural Sciences, Education, the Humanities, Health Sciences, and Economic and Management Sciences.

UFS staff will also be trained in teaching and translanguaging practices. Thus far, one lecturer has been nominated to track her use of translanguaging in the Academic Literacy classroom on the Qwaqwa Campus.

 

Multilingualism as a social asset

The fourth annual iCAN (Initiative for Creative African Narratives) was launched in April 2021. This project motivates students from all three campuses to write short stories in their mother tongue, and at the end of the year an anthology of stories will be published. In addition, some of the English stories will be injected into the English Academic Literacy courses for first-year students in order to localise the curriculum.

The Kovsies Multilingual Mokete will be hosted online this year and will include activities from the Bloemfontein, Qwaqwa, and South Campuses. The theme of this year’s festival is ‘Hearing you, hearing me’, ‘Ukungizwe, ukukuzwa’ (isiZulu), ‘Ons luister na mekaar’ (Afrikaans), and ‘Mmamele ke o mamele’ (Sesotho).

 

Academy for Multilingualism extending its footprint

A building that will house the academy on the Qwaqwa Campus is currently being built next to the new media lab. The building will comprise, among others, a 100-seater multipurpose lecture hall that can be converted into four smaller lecture halls. Similarly, a building for the academy is being constructed on the Bloemfontein Campus.

“The Academy for Multilingualism wants to ensure that the UFS becomes the South African leader in multilingualism, and at the impressive rate that they are delivering outputs, this goal will be reached soon,” says Dr Van Aardt.

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.
