Diversity, inclusivity, and transformation are what sets the University of the Free State (UFS) apart from other institutions of tertiary education. It instils in graduates the values of attention to detail and precision, being meticulous, adherence to deadlines, being honest, ethical, and taking the ‘moral high ground’.

Graduates at the UFS are also introduced to high levels of dedication and commitment, irrespective of the task at hand; taking pride in producing work of high quality; having a non-discriminatory mindset; the ability to be team players or leaders (depending on what needs to be done); and demonstrating an understanding and consideration for society at large.

This is the view of Ashley Hay, a successful UFS alumnus who completed his honours (accepted through the Recognition of Prior Learning process) and master’s degrees (graduating cum laude) in the Department of Urban and Regional Planning. Throughout his academic career, Hay has achieved good results and accolades such as Best Master’s Student, Best Master’s Dissertation, Best Research in Advanced Planning Practice, and also receiving membership of the Golden Key International Honour Society.

Today, he is employed by the Gauteng Provincial Government as Director: Land Use Management and Statutory Boards in the Office of the Premier and is in transition to a new branch called ‘Urban Planning’ under the Minister for Cooperative Governance, Urban Planning and Human Settlements.

He leads a team of professionals on spatial planning and land use management aspects, and particularly to monitor and support three metropolitan municipalities, two district municipalities, and six local municipalities in Gauteng. His achievements include the development of a policy document titled, Gauteng City Region Implementation Plan for SPLUMA, which was approved by the Provincial Cabinet Executive Council and endorsed by the Premier’s Coordinating Forum. At a previous place of employment, the uMshwathi Local Municipality, he was the author of one of the best Integrated Development Plans (IDPs), which received an award in KwaZulu-Natal.

Proudly UFS

Hay believes he was equipped with a set of values and skills to deliver services and to make a difference wherever he is. Not only through the resources and means available to him, but also with a high level of dedication to the general good of others – whether it is ordinary citizens or people who just need the very basics to uplift their livelihoods. “These basics should be forthcoming from the people’s government, which in turn implicates me among many other government employees,” he believes.

Hay says in the UFS Department of Urban and Regional Planning – from the administration team through to the lecturers and senior academics – everyone plays a role to instil a wealth of knowledge and expertise in students to understand and resolve societal problems. “It is the manner in which the course is conducted, the administrative facilitation, the steadfast pace of learning, as well as the personal attention to students, that have equipped us to later formulate solutions for everyday life challenges.”

He is convinced that these are the fundamental principles that graduates need to achieve academic excellence and make themselves employable in a competitive world.

Words that stick with Hay from his master’s classes, are those of the former Head of the Department, Prof Das Steyn, “Gain experience, build your capacity, and do something positive with the education you receive. Education is not what we teach you, it is what you do with it. Everyone gets the same degree, but some will fail with it and some will do something positive with it and make a difference”.

Standing out

And UFS graduates distinguish themselves in the workplace.

“In my work environment, the UFS graduates I know and have worked with are dedicated, goal-orientated, and passionate about the discipline. We go the ‘extra mile’ irrespective and have been able to apply the knowledge we gained from university towards problem-solving and contributing to make society a better place for all,” says Hay.

He also believes that the university has strong leadership and dedicated staff who actively respects the country’s rich diversity, acknowledging that we are an all-inclusive society, and creating a learning atmosphere that is transformed towards democratic principles.

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.
