Tobias van den Bergh, President of the Southern African Association for Counselling and Development in Higher Education (SAACHDE)

Tobias van den Bergh, Counselling Psychologist at the University of the Free State, has been appointed as the President of the Southern African Association for Counselling and Development in Higher Education (SAACDHE).  The appointment became official at the annual SAACDHE conference, which took place in Pretoria from 12 to 14 September 2022. As such, van den Bergh perceives this appointment as an opportunity: “To be part of a creative process that tackles the challenges faced in higher education and knowing the difficulty that students and my colleagues across the country are struggling with, accepting this appointment felt right.”

The role of SAACDHE

“The organisation represents members of several higher education counselling and career development centres from the SADC region. The organisation’s mission is to promote, guide, and advance best practices in centres at institutions of higher education,” explained Van den Bergh. Through this representation and assistance, members are able to provide quality support to the students they serve. SAACDHE members include mental health professionals, social workers, HIV/AIDS counsellors, researchers, and career development specialists from more than 15 higher education institutions in South Africa and Botswana. Furthermore, Van den Bergh asserts that, “SAACDHE represents its members through lobbying for increased institutional support, the promotion of scholarly, ethical, and best practices, and the training and development of professionals.”

Van den Bergh as President of the organisation

 As the newly elected President of the organisation, there are several challenges that Van den Bergh believes require the immediate attention of SAACDHE.  For instance, he maintains that student populations and the mental health challenges they face have grown at a substantial rate over the past few decades. However, the staff capacity in counselling and career development centres has not increased commensurately. As such, the challenge in this regard is that the need for mental health interventions continues to grow, but the capacity is not sufficient to deal with those challenges and to fill the gap in public mental health services. To address this challenge, he indicates that “the organisation is striving to innovate counselling centres, and to find ways to work smarter and be preventative where possible”.

In addition, Van den Bergh is adamant about ensuring that the organisation continues to be innovative in the way mental health services are provided to students, and to create practices that are culturally and contextually relevant. However, his long-term vision for the organisation is, “to continue serving as a training, development, and practice-based organisation, so that we can equip members with support and knowledge that will help them to continue helping students in a smarter and better way”.

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.
