Dr Maramura
Dr Tafadzwa Maramura says she carved her path by remaining focused and resolute on her journey.

The African proverb ‘it takes a village to raise a child’ conveys the message that it requires many people to provide a safe and healthy environment for children. The village gives the child the security needed to develop and be able to realise their hopes and dreams. 

Dr Tafadzwa Maramura believes that the same applies vice versa. “It takes a good child to be raised by a village. You need to understand that the village can only do so much, the rest lies on your shoulders as the child,” she says.

The journey of a child raised by a village
The senior lecturer reflects on the journey that led her to serve in the Department of Public Administration and Management at the University of the Free State. At the age of three, she lost her father, who was an army general in Zimbabwe. Soon after, her academic journey would begin at a boarding school. Her widowed mother then moved her to a mission school due to financial constraints, seeing that she had two more children relying on her for survival. Since her father served in the government, she qualified for a state scholarship, which saw her launch her academic career in South Africa as an undergraduate student. 

“I came to South Africa in 2010 and pursued a Bachelor of Social Science degree in Development Economics at the University of Fort Hare. Once my honours were conferred, I acquired my master’s within a year. Thereafter, I enrolled at the North-West University, where I completed my PhD within two years.”

Dr Maramura was the Vice-Chancellor’s valedictorian for her bachelor, honours, and 
master’s degrees. Graduating cum laude was another way of ensuring that she pays it forward to the village that raised her. Not only was she funded by the Zimbabwean government, but she also received financial aid from South Africa throughout her studies. 

Once a child, now part of the village 
Today, as founder of a foundation based in Zimbabwe, she pays the fees of orphaned and disadvantaged primary school learners. “I wish everyone could adopt a child, pay their fees, buy their schoolbooks – because we only have each other, we do not have anyone else. That’s also part of what I call co-creating.”

The Brightest Young Minds in Africa alumna goes above and beyond focusing on academics, as she believes that “if you are the only one holding the light, everyone else will have to follow behind you to make sure that they can see ahead. However, if you share that light, then it means many more can see, therefore making it easier to solve societal challenges as a collective”.

She argues that the amount of money you spend on lunch could pay a child’s school fees for a term, and the cash that you use to buy a jacket or a pair of shoes, could cover a child’s fees for a month.
Making a difference in the lives of young children is her way of playing the role of the village now that she is an adult. “I make sure that wherever I am, I make an impact in the lives of others.”

Dr Maramura says she plans to make sure that life is better for the next young African female, by setting up a mentorship programme for the next generation of leaders. In addition to that, her goal is to become an associate professor, rise in academic rank, and develop a research unit that can speak to issues of sustainable service delivery.

On how to be a good child 
You do not need to be a figure of authority to make an impact. According to Dr Maramura, all you need is a desire to co-create, and making sure that the public is in a different place after you have left the relevant office you hold or the organisation you serve. “Make sure that you can co-exist, because humans don’t live in a vacuum, we exist among each other.”

Serving the people makes all the difference. She suggests that everyone asks themselves what they are doing for their community, class, or family.

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.
