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.

Exploring numerous norms and assumptions that impede the investigation of racism and racial inequalities in university classrooms, was central to the scope of the research conducted by Dr Marthinus Conradie, a newly Y-rated National Research Foundation (NRF) researcher.

Support from various colleagues
He is one of 31 newly-rated researchers at the University of the Free State (UFS) and joins the 150 plus researchers at the university who have been rated by the NRF. Dr Conradie specialises in sociolinguistics and cultural studies in the UFS Department of English. “Most of the publications that earned the NRF rating are aimed to contributing a critical race theoretic angle to longstanding debates about how questions surrounding race and racism are raised in classroom contexts,” he said.

Dr Conradie says he is grateful for the support from his colleagues in the Department of English, as well as other members of the Faculty of the Humanities. “Although the NRF rating is assigned to a single person, it is undoubtedly the result of support from a wide range of colleagues, including co-authors Dr Susan Brokensha, Prof Angelique van Niekerk, and Dr Mariza Brooks, as well as our Head of Department, Prof Helene Strauss,” he said.

Should debate be free of emotion?
His ongoing research has not been assigned a title yet, as he and his co-author does not assign titles prior to drafting the final manuscript. “Most, but not all, of the publications included in my application to the NRF draw from discourse analysis of a Foucauldian branch, including discursive psychology,” Dr Conradie says. His research aims to suggest directions and methods for exploring issues about race, racism, and racial equality relating to classroom debates. One thread of this body of work deals with the assumption that classroom debates must exclude emotions. Squandering opportunities to investigate the nature and sources of the emotions provoked by critical literature, might obstruct the discussion of personal histories and experiences of discrimination. “Equally, the demand that educators should control conversations to avoid discomfort might prevent in-depth treatment of broader, structural inequalities that go beyond individual prejudice,” Dr Conradie said. A second stream of research speaks to media representations and cultural capital in advertising discourse. A key example examines the way art from European and American origins are used to imbue commercial brands with connotations of excellence and exclusivity, while references to Africa serve to invoke colonial images of unspoiled landscapes.

A hope to inspire further research
Dr Conradie is hopeful that fellow academics will refine and/or alter the methods he employed, and that they will expand, reinterpret, and challenge his findings with increasing relevance to contemporary concerns, such as the drive towards decolonisation. “When I initially launched the research project (with significant aid from highly accomplished co-authors), the catalogue of existing scholarly works lacked investigations along the particular avenues I aimed to address.”

Dr Conradie said that his future research projects will be shaped by the scholarly and wider social influences he looks to as signposts and from which he hopes to gain guidelines about specific issues in the South African society to which he can make a fruitful contribution.
