Prof Helena van Zyl, beloved, long-time academic and Head of the Business School at the University of the Free State (UFS), will retire at the end of June 2021 after arriving at the university more than 40 years ago and serving as Director of the Business School for 18 years. Prof Van Zyl has been a steady leader, not just in the Business School, but also for the vast array of students who made the UFS Business School their preferred choice. Starting out as a student assistant in the early ’80s in the then Department of Money and Banking, Prof Van Zyl progressed to become a junior lecturer in 1982, which placed her in a key position to eventually apply for Directorship of the Business School.

The journey

“The university went through some very tough and equally delightful times; during the nineties, strict austerity measures were implemented. In 1987, the department received its first computer; one for the entire department. The internet was from a different planet. Some of the senior academics refused to use the internet and emails. All their letters and other communication were still typed by appointed typists. I saw many rectors, deans, colleagues come and go – each management era had its own challenges and opportunities. In the end, it all worked out for the better,” says Prof Van Zyl.

“A highlight of my journey was the long road with my personal assistant, Alta Myburgh. I have known her since 1983 when she was a third-year student in my class, went on to become a student assistant, and with the exception of three years (if I remember correctly), she was next to me with loyalty that you will seldom find,” she explains. “When the Business School moved to its own address/building, it was certainly a highlight, but the ultimate was to contribute to students’ development and growth. For me, it has always been about the students and my staff,” says Prof Van Zyl.

Invest in students and employees

Prof Van Zyl believes that success builds on integrity and that contributing to the development and growth of students and employees is integral to the success of any institution. “To add value to people’s lives is very rewarding. One of the biggest lessons that I have learnt is that you need to empower the students and employees; invest in them, and they will invest in you. I am not convinced that we always got it right to manage our people correctly, but I guess this will remain an ongoing challenge,” she says. “I have learnt that if you create a platform of trust and belief in people, then they thrive,” explains Prof Van Zyl.

Looking forward

As Prof Van Zyl wraps up her journey at the UFS, she reflects on the past and what the future holds. “It was a privilege to work at the university, and I cannot extend enough gratefulness for all the opportunities I had. When I started working at the UFS, very few – if any – programmes were in place to assist new appointees with orientation, induction, etc., and you had to find your own way. I believe this has in a strange way contributed to one’s development and growth,” she says.

As for retirement, Prof Van Zyl is looking forward to travelling again, enjoy watching sport, gardening, and listening to classical music. “I will continue working part-time in the field of quality assurance, and also use this time to embrace new things. There is life after retirement,” she says.

Prof Van Zyl would like to be remembered for “sensitising people to seize the opportunities in life, and to make a difference – wherever you go, make a difference in your life and your work.”

Well wishes

Dr Liezel Massyn, Programme Director: BML Programme, UFS Business School

“Prof Helena embodies the Business School’s philosophy through the tagline, ‘Be worth more’. She challenges us to be worth more every day, in every aspect of our lives. She is a tough cookie. There are rules, and when you get to meet her, you learn very quickly that there is one way – the right way – to get things done. She asks tough questions and always strives to improve. She taught us the unwritten rules of the academic world, the academic knowledge of her field (whether you want to hear it or not), and life skills to survive and thrive in challenging situations. She is always willing to walk a thousand miles with you and has a deep concern for her staff and students – always interested in everyone’s story and continuously investing in people. Prof, thank you for not only living – ‘Be worth more’ – but also inspiring the next generation to make it part of our values.”

Dr Johan Coetzee, Senior Lecturer, Department of Economics and Finance

“Prof Helena taught me from my second year of study in 1997 and was instrumental in my development as a scholar. She has set an example for so many people of a strong woman who gets things done, while at the same time showing such compassion that you are inspired. The UFS is losing one of the ‘legends’ of yesteryear. She will be impossible to replace.”

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.
