Should the UFS continue to subscribe to academic journals that are behind a paywall?

On 12 May 2022, the University of the Free State (UFS) held an online seminar on Open Science, posing this question.

The seminar was facilitated by Prof Corli Witthuhn, Vice-Rector: Research and Internationalisation, who was joined by the following experts: Colleen Campbell from the Max Planck Digital Library (MPDL) in Munich, Germany, where she coordinates the Open Access 2020 Initiative; Ellen Tise, Senior Director of Library and Information Services at Stellenbosch University (SU); Glen Truran, Director of the South African National Library and Information Consortium (SANLiC); and Charlie Molepo, Deputy Director at the UFS Library Service. The discussion centred around the issues of accessing and publishing academic content behind a paywall, and what open access initiatives are doing to transition scholarly work to an open access (OA) paradigm.

“Publishing academic content behind a paywall not only limits access to scholarly work, but also prevents research output from being visible and making maximum impact,” the university stated.

Paywalls vs Open Access

A paywall is a figurative wall used to limit access to certain prestigious academic content. Overcoming this wall usually means a one-time purchase option where the reader buys the content from the publisher, or it could be subscription-based where you pay a subscription fee for a fixed period. OA, on the other hand, seeks to make any scholarly work freely available to anyone interested in accessing it, including those who cannot afford the subscription fees.

"Currently, authors are required to give up copyright of their research articles to publishers. We want to move to a fully open paradigm where authors can redeem and openly license their articles so that they are free to share, use, and reuse their work so that science can move forward faster. By making it open, we gain a wider possible readership that will help improve the quality of science,” Campbell said.

Furthermore, not only are publishers making a profit from subscription fees, but they also benefit significantly from hefty publishing and author fees.

“Researchers are paying to publish their research output, and libraries are paying to access it in what is known as double-dipping by publishers, leading to what we term ‘serial crisis’. Research institutions pay twice and still do not see their research widely available to be read.”

Transformative Agreements 

The panel explained the use of transformative agreements as a strategy to achieve full OA publishing. This strategy includes OA initiatives that organise investments around open research communication, demanding price transparency from publishers, as well as reorganising workflow and building up the capacity to make OA a default.

With Truran presenting statistics on OA in South Africa, he highlighted that “only 46% of South African journals are available freely, the rest are still out of reach of those who cannot afford to pay the costs associated with paywalls”. Tise touched on some negotiation principles for a transformational transition to OA. “Inclusivity and social justice must be core. Publishers must have an equity, diversity, and inclusion plan that addresses the challenges of researchers in the Global South.”

Should the UFS continue to subscribe to academic journals that are behind a paywall? 
Truran answered this question by saying: “If we’re going to cancel subscriptions, then we should do it in unity and at the appropriate time. At the same time giving transformative agreements a go."

In his closing remarks, Molepo clarified the university’s stance on OA: “The UFS has taken a decision to publish all our journals in-house. We have flipped from subscription to full OA, and in the process, have seen a huge improvement in terms of citation. The impact of those journals has improved drastically from 2015 to 2021. We are content with that. The route to OA is the route this university should be taking,” 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.
