A data scientist and research coordinator at the University of the Free State (UFS), in collaboration with his supervisor at the University of Pretoria (UP), is at the forefront of the fight against the Covid-19 virus with accurate data and analysis.
Herkulaas Combrink of the Centre for Teaching and Learning at the UFS and PhD candidate in Computer Science at the UP, said accurate data is important to prevent widespread panic and sensationalism during a global disaster such as the current pandemic. This information helps people to make informed decisions and to reduce their exposure to the threat of the virus.

Assisting decision-makers

“I, along with colleagues from the World Health Organization, the Centers for Disease Control and Prevention in the USA, the provincial office of the Centers for Disease Control and Prevention, provincial clinicians, and the Free State Department of Health led by Dr David Motau, have been able to progress significantly in terms of evidence-based tools to assist provincial and national decision-makers during these turbulent times.”
“It does come at a cost, though, in that we have worked continuously since the lockdown, dedicating all our time and efforts to the department from all over to ensure that we are not part of some of the global statistics we have seen,” said Combrink. 

A paper written together with his supervisor, Dr Vukosi Marivate, has also been accepted by the Department of Higher Education and Training (DHET)-accredited Data Science Journal.  This paper is related to a framework for sharing public data to the public in a way that is useful, usable, and understandable. 

Ongoing projects

Combrink said it is hard to name all those who are/were involved in the great work done by the Free State Department of Health, but some of them include Dr Elizabeth Reji (Head of Department, Family Medicine), Dr Collin Noel (surgeon, senior lecturer at the UFS), Dr Sammy Mokoena (community health registrar, UFS), Dr Ming-Han Motloung (public health medicine specialist, senior lecturer, UFS), Dr Perpetual Chikobvu (Director: Information Management at the Department of Health, affiliated lecturer at the UFS), as well as Alfred Deacon (lecturer at the UFS), who have worked at some point during this short space of time on one of the many projects. 

Some of the projects include the following:

• A provincial database for screening and monitoring.
• A data pipeline and assembly of hospital information flow, liaised with the NICD, Vodacom, and the different district managers to ensure that the pipeline occurs in a timely manner.
• Digitised paper-based capturing tools for rapid data capturing and processing.
• Incorporated state-of-the-art visualisation tools to action data into useful information for decision-makers in certain areas.
• Provided both provincial and national projections, stress testing different scenarios using a variety of statistical, computational, and/or machine-learning approaches to add to the already existing projections of the Council for Scientific and Industrial Research (CSIR).
• Training healthcare professionals in the field to apply these tools within their own districts.
No easy task

“These aforementioned feats were by no means easy and are not completed yet, but we are getting there. In the foreseeable future, I will be working closely with national and international researchers to deploy a tool for hospital managers in the Free State that will assist them when we move from level 5 to any level below.”

“In addition to this, I am constantly providing support to the Free State Department of Health regarding any analysis required for decision-making purposes. The teams we work in comprise highly competent individuals with a passion for solving problems from multidisciplinary perspectives,” according to Combrink.

International speakers discuss diversity

International and local experts recently gathered on the Bloemfontein Campus to deliberate over the topic of diversity.

Student participation and mobility dramatically increased in higher education worldwide. Cultural, political, economic and social factors on a national and global scale, have brought the reality of diversity into the operational spaces of Higher Education Institutions. These challenges are not exclusive to South Africa, though. In the Netherlands and USA, universities are also challenged by the demands of an increasingly diverse student population.

Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, acted as one of the keynote speakers during a two-day colloquium hosted by the Institute for Reconciliation and Social Justice. In an impelling address, Prof Jansen argued that change cannot be affected on a university campus if the surrounding community does not change as well. He also noted the spread of a culture of silence surrounding issues of misbehaviour. He urged that we need to find courage again to speak out. From the level of government, media and churches to the private spaces of our homes, we have to co-create an environment of care.

This message closely tied in with that of Prof Shirley Tate’s from the University of Leeds. In her keynote, she asserted that mere tolerance of someone different from you can lead to even more alienation. The path to true reconciliation is grounded in the intimacy of friendship. Friendship and empathy lead to trust and transcend racism.

Another keynote speaker from abroad, Dr Charles Alexander from the University of California, delineated a model for inclusive excellence. He explained that the major problem of true transformation is not due to a lack of ideas, but in the implementation thereof. “Realities of implementation short circuit the change process,” he said. He explained how campus environments can adapt in order to support and enhance lasting inclusivity.

We have to become complicit in the process of transformation, Prof Dr Ghorashi, Professor of Diversity and Integration at the Vrije Universiteit Amsterdam, conveyed. Linking up with the issue of silence, she demonstrated the power of speaking out, using examples from her extensive research among victims of violence. It is imperative, she maintains, that for transformation to materialise, we need to create safe spaces in which we can share our vulnerabilities.

Footnote: Due to unfortunate circumstances, both Prof Dr Ghorashi and Prof Shirley Tate could not personally attend the colloquium as planned. Their respective keynotes were read to the audience on their behalf.
