Dr Matteo Grilli from the International Studies Group (ISG) became the second ISG scholar in just four years to receive a coveted P-rating from the NRF.

A P-rating (Prestigious Awards) by the National Research Foundation (NRF) is the holy grail for all young researchers at all South African universities and across all disciplines. It is a valuable tool for benchmarking local researchers against the best in the world. But it is hard to come by. Only one or two researchers are normally granted this sought-after standing each year. 

Dr Matteo Grilli, a young Italian historian from the International Studies Group (ISG), says he was “pleasantly surprised” when he recently got the nod from the NRF, attributing his P-rating to the “excellent training and support” that he received from the UFS, and specifically the ISG and its head, Prof Ian Phimister.  

Unique achievement for ISG
What makes this achievement even more significant, is that the ISG produced another P-rated scholar a mere four years ago (Dr Daniel Spence in 2016).

“For Prof Phimister to produce two P-rated researchers in such a short time is really an unbelievable achievement. I am not aware of any other department at any South African university that could achieve this,” says Dr Glen Taylor, Senior Director: Research Development. 

P-rating requirements
The NRF’s P category honours young researchers (normally younger than 35 years) who have held a doctorate or equivalent qualification for less than five years. Researchers in this group are recognised by all or the vast majority of reviewers as having demonstrated the potential to become future international leaders in their field based on exceptional research performance and output from their doctoral and/or early postdoctoral research careers.

UFS becoming a mecca for African studies
Dr Grilli produced his first book, Nkrumaism and African Nationalism: Ghana's Pan-African Foreign Policy in the Age of Decolonisation around two years ago, after being accepted as a postdoc scholar by the ISG in 2015.

This unique research centre was established towards the end of 2012, with the aim of attracting and recruiting high-calibre postgraduate students and postdoctoral fellows from all over the world to the UFS. 

“Working at the ISG has undoubtedly been the best experience of my life and made me the solid scholar I am today. At the ISG, I found the best working environment you could possibly have in an academic setting, even compared to the Northern Hemisphere,” Dr Grilli says.

He believes the centre’s strength lies in the “exceptional exchange” that researchers have with their peers, allowing them to not only master their research subject but also to learn from other members’ research and methodologies.

“In my view, the ISG is concretely contributing to bringing the centre of African studies back to the African continent,” he enthuses.

Passion for Southern African politics
Dr Grilli specialises in the political history of Ghana and Southern Africa, focusing on transnational histories of African liberation movements, the history of Pan-Africanism, the Cold War and decolonisation in Africa, and the history of European migrations in sub-Saharan Africa (particularly Italian communities in Ghana and the Congo DRC). 

He is currently working on a book project about the history of Pan-Africanism, Socialism, and Nationalism in Southern Africa, particularly in Lesotho, eSwatini, and Botswana.

Asked what advice he had for young researchers, he echoes the counsel he received from Prof Phimister at the start of his tenure at the ISG: 

“Always aim high. Don’t be intimidated by the fact that there is a lot of competition in the academia, nor that you might be disadvantaged because you work in the Global South. If you work hard, your research will speak for itself and you will be able to publish solid works even in the most prestigious journals of the Northern Hemisphere.”

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.
