Keabetswe Modise is graduating cum laude with a Bachelor of Administration Honours degree during the UFS virtual graduation on 19 April.
After repeating Grade 11 three times, a student in the Faculty of Economic and Management Sciences at the University of the Free State (UFS) is graduating cum laude with a Bachelor of Administration Honours degree in April.

Keabetswe Modise, who is graduating on 19 April during the UFS virtual graduation, says she used her earlier failures as motivation to work even harder. 

“I am extremely proud of myself. I chose to win instead of crying over spilled milk. As a black, capable, and independent woman, I told myself that if there is a chance for trauma or depression, there is definitely a chance to succeed and enjoy life. This implies that I can achieve anything that I set my mind to. I now hold my family’s name high in both our community and within our external family,” says a proud Modise.

Modise, a part-time lecturer at the Central University of Technology (CUT) in Welkom, has been accepted to study a Master of Public Policy and Development degree in Japan. Her academic year will commence early in 2022 and will take two years to complete.   

Motivation

“This (academic success) came as a surprise. I never thought that one day I would hold a postgraduate qualification, let alone that such a qualification exists. In high school, I repeated Grade 11 three times. At that time, I was known as the dumbest kid in school and in the community. 

“I was depressed, but I did not know what was going on with me. Therefore, I just wanted to pass my matric and work to survive. During my matric year, I really became more motivated after career orientation. This is when I knew I wanted to experience university life. I also wanted to use the chance to escape the dumb girl concept and come back with a victory to claim back my name. Today I am the most influential girl in my community.”

Making the most of the lockdown

Modise used the COVID-19 pandemic and the lockdown to her advantage, as it gave her the opportunity to not only study online, but to also start a successful fast-food business. 

“The consequences of the pandemic on universities have been to my advantage. I managed to work at home, with limited financial expenses such as transport and printing of documents. Also, my assessments were online. This also gave me the chance to start a fast-food business while tackling academic activities on time. 

“Most importantly, I did not have money for registration, and when the policy changed for late registration due to COVID-19 regulations, it gave me time to make a plan to finance my studies. Fortunately, by August, I received a bursary from the Postgraduate School at the UFS, because the HOD was impressed with my academic record. As much as the effects of COVID-19 were devastating on the lives of people, I managed to achieve my goal,” says Modise. 

Her inspiration 

According to Modise, her parents – who separated when she was very young – inspire her. Says Modise: “I appreciate everything they have done for me. I just want my father to one day address me as Dr Modise, while he and my mother can look back and be proud of the woman I have become.” 

“In this case, I can say that I get inspired by the vision of being applauded by both my mother and father.  Most importantly, I get inspired by the changing philosophy of government management. I admire the impact of globalisation around the world. Today, any academic institution can operate online.” 

Modise’s message to others is that nothing comes easy or without a cost: “It looks like it is impossible, but actually, this is your life. I can motivate someone as much as I can, but if you are not willing to be motivated, nothing can change for you. Also, no one owes anyone anything. This is your journey, drive it.”

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.
