The International Studies Group continues to keep critical issues in Africa on the research agenda, with two of its postdoctoral research fellows awarded prestigious international research grants.

Dr Hlengiwe Dlamini won a CODESRIA (Council for the Development of Social Science Research in Africa) award as part of the organisation’s ‘Meaning-making Research Initiatives’. These initiatives focus on supporting research that contributes to agendas for imagining, planning, and creating African futures.

“I was over the moon when I heard that I received this award!” says an excited Dr Dlamini. “The competition was a tough one. Applications were received from 430 female applicants and just 12 were retained, including mine.”  
 
Her colleague in the ISG, Dr Kundai Manamere, who recently signed a book contract with Ohio University Press, has been awarded an African Peacebuilding Network (APN) 2020 Individual Research Fellowship, administered by the American Social Science Research Council.

“I am delighted to have received this award. As an early-career scholar, this is one of my several goals, and achieving it recognises and validates my work. This boosts my confidence and encourages me to keep working hard,” says Dr Manamere.

Examining border disputes
Dr Dlamini’s research project is a comparative study of two border disputes – between Cameroon and Nigeria over the Bakassi Peninsula borderland, and between Eswatini (formerly Swaziland) and South Africa over the demarcation of their borders, and how the international doctrine of uti possidetis juris, as an instrument of inter-state conflict resolution, applies to these disputes.

“The doctrine of uti possidetis juris (literally translated: as you possess, thus may you possess) states that frontiers inherited from colonialism cannot be changed under any circumstance. Cameroon won its case in the International Court of Justice in 2002 in its border dispute with Nigeria and this had a direct impact on Eswatini, which also had a border dispute with South Africa,” she explains.

“The post-apartheid South African governments have been hostile to the idea of adjusting their borders with Eswatini, while the Eswatini monarchy has relentlessly been pursuing what it calls ‘its stolen territories by the British and the Boers in the 19th century’.”

Dr Dlamini will be heading a team of four female researchers from different nationalities. As soon as international flights resume, two scholars from Canada and Sweden will head for Cameroon, while she and another researcher will start with archival research in Southern Africa, before embarking on fieldwork.

“There will be no rest for us. It is incumbent on me to assemble the data collected and use it to write two or three scholarly articles for journal publications,” says Dr Dlamini.


Migration issues and public health interventions
Dr Manamere’s research focuses on documenting the experiences of former refugees and their host communities at Chambuta refugee camp, one of the five refugee camps established by the Zimbabwean government along the Mozambican border in the 1980s to accommodate asylum seekers fleeing from the Mozambican civil war.
“The project explores their experiences and examines their perceptions about conflict, displacement, refugee conditions, and the occurrence of diseases and intervention following a disease outbreak that killed nearly 200 people in August 1992. I use the Chambuta case to reflect on the politics of voice and representation in history – how official reports by governments and non-governmental organisations overshadow the experiences of refugees and host communities.”

The COVID-19 lockdowns in both South Africa and Zimbabwe have delayed Dr Manamere’s fieldwork plans. She will now first spend time collecting information from digitised archives and doing telephonic and online interviews.

ISG a melting pot for international research talent
Both researchers expressed their appreciation for the role the ISG has played in shaping their academic careers.
“By creating opportunities for me to network with renowned historians in my field, the ISG has expanded my circle of mentors. All these opportunities culminated into several achievements, including this award, forthcoming articles in leading international journals, presentations at international conferences, and a book due to be published by the Ohio University Press, one of the leading Africanist publishers in the world. To me, this is the best foundation for a successful academic career, and I am proud to be part of the group,” says Dr Manamere.

“The ISG creates one of the most convivial environments for intellectual production.  We are really flying high. The scholars of the ISG are making their mark in different ways. I am very grateful for the Stanley Trapido seminar series and other academic activities that constitute a vital crucible for the cross-fertilisation of our minds and for the acquisition of new methodologies and updates in our disciplines,” says Dr Dlamini.

Prof Ian Phimister, Head of the ISG, says the two researchers have brought great credit to the UFS and the ISG.“By winning such prestigious awards, Drs Dlamini and Manamere show themselves to be first-rate scholars. Their academic commitment and drive are exemplary. At the same time, their research projects, respectively on comparative African territorial boundary disputes and on Mozambican refugees' experiences of civil war, drought, and disease, have significant policy-making implications.”

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.
