Prof Francis Petersen, UFS Rector and Vice-Chancellor opened the workshop on Monday, 10 February 2020.

Will an enclaved state work in a country like South Africa? How can universities produce graduates who will become engaged citizens, and what is the current status of the ANC and the DA? These were some of the key topics at a workshop on South Africa and Africa: Prevarication at the Precipice, hosted by the Department of Political Studies and Governance at the University of the Free State (UFS). 

The two-day workshop is an annual collaborative discussion platform between the UFS, chaired by Prof Hussein Solomon, the Southern African Centre for Collaboration on Peace and Security, and the Osaka School of International Public Policy

The workshop opened with Prof Francis Petersen, the UFS Rector and Vice-Chancellor who delivered his message from the perspective of higher education. 

He spoke about the importance of universities in South Africa being able to produce graduates who will become active citizens. 

Graduates should fulfill their role in society 

“Universities should be the place where we should educate and engage to let our students and graduates know what society should look like. If we don’t do that transformative thinking among our graduates we are going to perpetuate what society is,” Prof Petersen said. 

“I hope this conference won’t just debate the issues because we already know the answers. I hope this workshop will say what we need to do as active citizens to ensure that we start new building steps. International engagement is also important. As is our engagement with the continent.” 

Helen Zille on the State of South Africa 

Helen Zille, Chairperson of the DA Federal Council presented a talk on the State of South Africa in which she tabled three variables she believes can save the country from the precipice. “There should be three variables which can make a democracy work; a separate state (not a party-ruled state), the rule of law and a culture of accountability,” Zille said. 

Zille tabled the concept of an enclaved state a state which operates independently from party control. “There are increasingly isolated states in SA which are being pushed out of good governance and service delivery. An example of an enclave that functions well is the “justice enclave (Supreme Court of Appeal) in Bloemfontein”. 

She reiterated the importance of active citizenship. However she added that people who are active citizens are usually not the ones elected to office.

The role of active citizenship and the state of the country cannot be discussed in isolation from the state of the ruling ANC and the official opposition, the DA. Prof Dirk Kotze from the Department of Political Studies at Unisa, and Bonolo Selebano, Netwerk 24 political journalist, gave a glimpse into the status of Luthuli House (ANC headquarters in Johannesburg), and the DA. 

“ANC party politics are not unique. They are following a global trend. However, the credibility of the ANC is a big issue,” said Prof Kotze. In the political arena globally, political parties are redefining themselves and it is important for the ANC to figure out where it finds itself. Selebano wasn’t too optimistic about the DA either, saying the party should return to its liberation ideals.

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.
