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.

Fight against Ebola virus requires more research

Dr Abdon Atangana, a postdoctoral researcher in the Institute for Groundwater Studies at the University of the Free State (UFS), wrote an article related to the Ebola virus: Modelling the Ebola haemorrhagic fever with the beta-derivative: Deathly infection disease in West African countries.

“The filoviruses belong to a virus family named filoviridae. This virus can cause unembellished haemorrhagic fever in humans and nonhuman monkeys. In literature, only two members of this virus family have been mentioned, namely the Marburg virus and the Ebola virus. However, so far only five species of the Ebola virus have been identified, including:  Ivory Coast, Sudan, Zaire, Reston and Bundibugyo.

“Among these families, the Ebola virus is the only member of the Zaire Ebola virus species and also the most dangerous, being responsible for the largest number of outbreaks.

“Ebola is an unusual, but fatal virus that causes bleeding inside and outside the body. As the virus spreads through the body, it damages the immune system and organs. Ultimately, it causes the blood-clotting levels in cells to drop. This leads to severe, uncontrollable bleeding.

Since all physical problems can be modelled via mathematical equation, Dr Atangana aimed in his research (the paper was published in BioMed Research International with impact factor 2.701) to analyse the spread of this deadly disease using mathematical equations. We shall propose a model underpinning the spread of this disease in a given Sub-Saharan African country,” he said.

The mathematical equations are used to predict the future behaviour of the disease, especially the spread of the disease among the targeted population. These mathematical equations are called differential equation and are only using the concept of rate of change over time.

However, there is several definitions for derivative, and the choice of the derivative used for such a model is very important, because the more accurate the model, the better results will be obtained.  The classical derivative describes the change of rate, but it is an approximation of the real velocity of the object under study. The beta derivative is the modification of the classical derivative that takes into account the time scale and also has a new parameter that can be considered as the fractional order.  

“I have used the beta derivative to model the spread of the fatal disease called Ebola, which has killed many people in the West African countries, including Nigeria, Sierra Leone, Guinea and Liberia, since December 2013,” he said.

The constructed mathematical equations were called Atangana’s Beta Ebola System of Equations (ABESE). “We did the investigation of the stable endemic points and presented the Eigen-Values using the Jacobian method. The homotopy decomposition method was used to solve the resulted system of equations. The convergence of the method was presented and some numerical simulations were done for different values of beta.

“The simulations showed that our model is more realistic for all betas less than 0.5.  The model revealed that, if there were no recovery precaution for a given population in a West African country, the entire population of that country would all die in a very short period of time, even if the total number of the infected population is very small.  In simple terms, the prediction revealed a fast spread of the virus among the targeted population. These results can be used to educate and inform people about the rapid spread of the deadly disease,” he said.

The spread of Ebola among people only occurs through direct contact with the blood or body fluids of a person after symptoms have developed. Body fluid that may contain the Ebola virus includes saliva, mucus, vomit, faeces, sweat, tears, breast milk, urine and semen. Entry points include the nose, mouth, eyes, open wounds, cuts and abrasions. Note should be taken that contact with objects contaminated by the virus, particularly needles and syringes, may also transmit the infection.

“Based on the predictions in this paper, we are calling on more research regarding this disease; in particular, we are calling on researchers to pay attention to finding an efficient cure or more effective prevention, to reduce the risk of contamination,” Dr Atangana said.
