The newly appointed editor of the University of the Free State(UFS) journal for humanities Prof Henning Melber had vowed to give the publication a deeper insight on critical issues ranging from decolonisation of knowledge to knowledge production.

In his first editorial opinion as the new Editor of the Acta Academica journal, Prof Melber said the publication has the declared intention to apply a critical social theory perspective.

“Dedicated to scholarship in the humanities, Acta Academica will henceforth be published annually with a minimum of two issues, plus an optional additional issues per year,” he said. 

Former Editor Professor Lis Lange, previously Vice-Rector: Academic at the University of the Free State (UFS), has moved to the University of Cape Town as Deputy Vice-Chancellor for Teaching and Learning.

The journal publishes scholarly articles that examine society, culture and politics from a critical social theory perspective and it is also interested on scholarly work that examines how the humanities in the 21st century are responding to the double imperative of theorising the world and changing it.

Analysis on Africa encouraged for Acta Academica

As a journal promoting humanist values and ethics, Prof Melber stated that he would like to see Acta Academica publishing scholarly analysis and think pieces that engage with such challenges in a critical (and gendered) theoretical perspective. 

“We welcome in particular contributions that link to current themes and processes on the African continent and especially to Southern Africa, without abandoning the global context and the shared perspectives of committed
scholarship elsewhere,” he said.

Decolonisation of knowledge

“We will promote an emphasis on contributions in the fields of post-colonial, development, cultural, gender, international and African Studies aiming to support current efforts towards a decolonisation of knowledge and knowledge production. 
He said the journal will combine an international post-colonial discourse inspired by critical theory and other relevant schools of thought applied to and/or generated in a local and regional (African) context. 

“We also welcome efforts to contribute to the decolonisation of knowledge, which still to a large extent is anchored in the global asymmetries. We cannot pretend these asymmetric power relations and inherited structures do not exist.  “Nor will we be able to avoid their reproduction completely. But we can promote ownership of authors over their intellectual product and will disseminate the work as widely as possible,” he said.

New Editor calls for diversification of knowledge

In another efforts to decolonise, Prof Melber said they would also make special efforts to empower aspiring African scholars. As part of this endeavour, the UFS’s Centre for Gender and Africa Studies has for several years, been the partner institution of Africa Spectrum for the annual Young African Scholars Award. 

“We will try to create similar opportunities, encouraging early career scholars to submit articles. In addition, we would like to expand the character of contributions, by further diversification of forms of knowledge transmission through debate articles, reports, comments, review essays and other thought-provoking interventions. We hope to receive your support, as potential authors or as readers who contribute to or benefit from Acta Academica’s efforts to further a stimulating debate,” he said

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.
