Research group rethinks white societies in Southern Africa

Poor, Precarious, White? Rethinking white societies in Southern Africa, 1930s-1990s is a two-day workshop that was recently convened by the International Studies Group (ISG) with financial support from the office of the Vice-Rector: Academic, on the University of the Free State’s (UFS) Bloemfontein Campus. The event drew together a range of historical research on poor and working-class whites across Southern Africa during the twentieth century, with the goal of uncovering wider histories of race. 

In his welcoming speech, Prof Francis Petersen, Rector and Vice-Chancellor of the UFS, stated that race and its histories have taken on a new and renewed significance, not only in South Africa, but also globally. He said, “I am very proud to see the ISG organising and hosting such a wonderful workshop. It has attracted some of the leading intellectuals in the world on critical studies related to whiteness, and though its focus is on the histories of whites, I am pleased to see that a large number of presentations concern the wider questions of race.”

Mentioning several areas of concern on the world scene, such as policies issuing forth from the Trump government in the USA, violence against new migrants across Europe, as well as challenges of race as exhibited by specific events at the UFS, Prof Petersen said that it is particularly significant for this event to be hosted on one of our campuses. Quoting from Prof Neil Roos’ inaugural lecture held the previous evening, Prof Petersen added, “The histories of race offer the opportunity to rethink the approaches and methodologies of social history, and thus revitalise … the discipline.”

Participants in the workshop came from across Southern Africa, Europe, and the United States, and included leading scholars in the field. The first keynote was by the author of the acclaimed book The Wages of Whiteness: Race and the Making of the American Working Class (published in 1991), Prof David Roediger, who currently serves as Foundation Professor of American Studies and History at the University of Kansas. In his keynote entitled Settlers and Immigrants in Critical Whiteness Studies, Prof Roediger dealt with topics such as Southern Whiteness and Indigeneity in Australia and New Zealand, the relationship between migration and race, as well as how the current focus on the role of the white working class in the election of Donald Trump overlooks the complicity of the middle-class and elite whites who also supported him.

The second keynote address was delivered by Prof Jonathan Hyslop of the Colgate University, on the topic Workers called White and Classes called Poor: The ‘White Working Class’ and ‘Poor Whites’ in Southern Africa, 1910-1994. Prof Hyslop offered a sweeping overview of poor and working-class white experiences in Southern Africa, suggesting attention to comparisons and connections as a way of analysing and understanding the history of the region. 

The workshop was organised by Drs Danelle van Zyl-Hermann and Duncan Money, both Postdoctoral Research Fellows in the ISG, in conjunction with Prof Neil Roos, who is also based in the ISG. The research papers presented at the workshop covered topics as diverse as the experiences of white female civil-service employees in colonial Zimbabwe, French immigrants to the apartheid-era Vanderbijlpark steelworks, and white working-class resistance to state regulation. The papers are to be published in an edited collection which will be included in the Routledge African Studies series.

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.
