Opinion article by Prof Sethulego Matebesi, Academic Head of Department, Associate Professor: Sociology, University of the Free State .


In Teams of Rivals, author Doris Goodwin notes how former American president Abraham Lincoln created value by surrounding himself with people who have the capacity and the tenacity to challenge him. Despite many of the challenges he faced throughout his presidency, he managed to build a common cause with his cabinet to foster the interests of Americans. In a completely different text, Crisis of Conscience: Whistleblowing in an Age of Fraud, Tom Mueller laments how people fail to act out of apathy, complicity, or fear. 


These two distinct texts raise the question of how leadership should react to criticism and the requisite degree of freedom of speech that public representatives should have. 


Similarly, the back-and-forth saga between Tourism Minister Lindiwe Sisulu and President Cyril Ramaphosa over whether she apologised for her opinion piece that criticised black judges, effectively drills home a longstanding historical lesson. This lesson is that political astuteness is a phenomenon as old as the history of politics itself.

Although the astuteness shown by Sisulu against critics from her political party may be puzzling, her public exchanges that a statement by President Cyril Ramaphosa was a ‘misrepresentation’ of their meeting are more puzzling. 
But why is this puzzling? What are we to do about what some call a show of unprecedented defiance and others assertiveness? We also need to ask whether Sisulu’s stance can be adequately explained by those who label her as being arrogant and who deserve to be fired by President Ramaphosa.

A political travesty to apologise on behalf of Sisulu

Public apologies are a common occurrence globally. They often come by way of assuming guilt, expressing remorse, and admitting responsibility. Thus, proper apology etiquette requires the ‘wrongdoer’ to deliver the apology. However, this was not the case with Minister Sisulu.

Sisulu acted in a very public way with her opinion piece and her response to the ‘apology in her name’ released by the presidency. Certainly, with her experience as a public figure, she was aware of the implications of her actions.

Furthermore, she was consistent with her narrative against criticism directed towards her. Yet, we do not know why the presidency saw the need to apologise on behalf of Sisulu. Perhaps it had unreasonable expectations that Sisulu would publicly accept what she disagreed with privately.

Notwithstanding the sincerity of the presidency in dealing with this matter, supporters of President Ramaphosa will, on the one hand, be disillusioned by this own goal. At the same time, those who support Minister Sisulu may be encouraged by her steadfast refusal to accept a coerced apology used as a shaming mechanism. She inadvertently represents a dynamic articulation of an alternative repertoire of contention within the ANC.

Lately, we have witnessed a surge of nationalism globally during the COVID-19 pandemic. The Economist referred to the narrative battle between China and the United States over the pandemic as a ‘new scold war’, threatening to tear the world apart. But, as this Sino-US relationship reminds us, what is at stake is less the tit-for-tat scold war between Sisulu and Ramaphosa that threatens to spiral out of control, than the subdued attempts to attain constituent support within the ANC.

Sisulu herself has never publicly indicated her availability to contest the presidency of the ANC at its next elective conference. By any measure, if she does have such aspirations, stepping forward and engaging politically is one thing, but open defiance of authority is another. Since there are no permanently privileged constituencies in political malaise created by regeneration projects such as the organisational renewal drive of the ANC, the struggle to articulate and establish the interests of those who are aggrieved within the party is an ongoing process.

But where does this leave President Ramaphosa?

Many commentators have noted that his long game is no longer effective. However, President Ramaphosa wants to upend the notion that robust debates within the structures of the ANC are not tolerated. He is wary of the propensity of ANC structures to support those who are victimised. And while the scold war is in full swing, others will join in trying to win the hearts and minds of ANC members.

Meanwhile, when failure to act decisively in the face of predictable situations facing the country, particularly during a crisis; we can then no longer talk about protecting the interests of South Africans.

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.
