Office dynamo obtains masters in reconciliation- nathlene van wyk

Nathlene van Wyk hails from the rural town of Douglas in the Northern Cape, but this dynamic Office Manager for the Dean: Faculty of Theology and Religion has a knack with people, having obtained her undergraduate and honours degrees in Industrial Psychology. At a graduation ceremony held on 28 June 2018 at the Bloemfontein Campus of the University of the Free State (UFS), Nathlene also received her Master’s Degree in Reconciliation and Social Cohesion.

Devoted mother, avid student
Nathlene credits her success to the support system she had within her family. She says: “I would never have been able to complete this degree without the support of my husband, Feris. I spent my Saturdays and Sundays in the office, busy writing and doing assignments while he looked after our two daughters, aged three and five, and made sure everything at home ran smoothly.”

In addition, Nathlene experienced her mother’s loving support. She says: “I have much to be grateful for towards my mom, Maureen Morolong. As a single mother, she went to great lengths to ensure that I gained a good education. On days that things were especially difficult, her prayers and encouragement carried me through. She often repeated the saying: ‘It’s not how you start, it’s how you finish.’ This kept me motivated when the days seemed too short and discouragement set in.”

Brimming with pride
Prof Fanie Snyman, Dean of the Faculty of Theology and Religion, says of Nathlene’s achievement: “I am immensely proud of Nathlene. To study for a master’s degree while keeping up with a demanding position at the faculty, as well as the responsibilities of being a wife and mother is not easy. The university at large and the faculty in particular are still in a process of transformation and I think the research Nathlene did will benefit us in our efforts to transform the university.”

Nathlene says: “I always had an interest in social and political issues. With continued protest, interracial conflict, inequality and poverty, it became clear to me that 23 years after the dawn of democracy, our country is still very much battling to rid itself of the traumatic legacies of apartheid. For me, this is why the whole notion of reconciliation needs to be rethought and re-evaluated. Completing this degree allowed me to do just that: To critically evaluate our current state of affairs while applying theoretical frameworks that can help us to explain and understand our society better.”

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.
