From 21 to 23 November, more than 160 delegates gathered at the Golden Gate Highlands National Park in the Eastern Free State for the fourth biennial conference on Scholarship of Teaching and Learning (SOTL) in the South, dubbed SOTL 4 the South.

This year’s iteration was proudly hosted by the University of the Free State (UFS) and organised by Dr Jared McDonald, Chief of Staff in the Office of the Vice-Chancellor and Principal; Dr Eleanor Bernard, Assistant Director in the Centre for Teaching and Learning on the UFS Qwaqwa Campus; and Prof Zach Simpson, Editor-in-Chief of the SOTL in the South journal. Established and emerging scholars, as well as postgraduate students working in the field of teaching and learning from across disciplines in Southern Africa, came together to share ideas, debate perspectives, and learn from experiences related to the conference theme: Teaching and Learning for Sustainable Futures.

The programme included presentations on a wide variety of topics, such as the challenges and opportunities of artificial intelligence in higher education, academic literacy, student success, teaching and learning for sustainable development, curriculum design, and digital futures. The programme also included two keynote presentations by leading scholars in education for sustainability, Prof Heila Lotz-Sisitka, Distinguished Professor and SARChI Research Chair in Global Change and Social Learning Systems in the Environmental Learning Research Centre at Rhodes University, and Prof Kasturi Behari-Leak, Associate Professor of Higher Education Studies and Dean of the University of Cape Town’s Centre for Higher Education Development.

The organisers were delighted with the quality of the scholarship that was shared. “This conference has been 18 months in the making, and we are grateful to all the delegates for embracing, and engaging with, the conference’s theme. We are also appreciative to all the reviewers on the Scientific Review Committee who were generous with their time, reflections, and critiques in assisting us to deliver a compelling, impactful programme,” said Dr McDonald. Dr Bernard added that “the conference would not have been possible without the generous support of the University of the Free State’s Executive Management and Centre for Teaching and Learning, as well as the senior management of the Qwaqwa Campus, who have supported the conference from the time it was just an idea”.

Prof Zach Simpson expressed his gratitude to the UFS for its support and assistance. “The last in-person conference of SOTL in the South was in 2019, before the COVID-19 pandemic. It was wonderful to see so many scholars come together in a beautiful location to engage with a compelling and topical conference theme.” Selected papers have been invited to contribute to a special issue of SOTL in the South, edited by the organisers and due for publication in mid-2024.

SOTL is an informal ‘body’ that is not affiliated with any particular parent organisation or institution. Its aim is to advance scholarship in teaching and learning across the Global South – conceived of not just in geographic terms – but as concerned with questions of power, access, inequity, and marginalisation, even where these might be present in the Global ‘North’. Moreover, it aims to give voice to novice SOTL practitioners and to serve as a platform for academics, particularly novice academics, to contribute their scholarly work.

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.
