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.

UCT scholar in Philosophical Psychology of Black Existence to join Judge Albie Sachs on stage
2015-03-23

Dr Buhle Zuma, listed as one of the 2011 Mail & Guardian 200 Young South Africans, is coming to the Bloemfontein Campus. He will share a stage with civil rights activist and former Constitutional Court, Judge Albie Sachs, on Thursday 26 March 2015 in the Albert Wessels Auditorium at 12:30.

Respondent to Judge Sachs

A former Mandela Rhodes scholar, and currently a young lecturer at the University of Cape Town's Psychology Department, Dr Zuma is particularly interested in issues at the heart of our rainbow nation . His research asks the question: What does it mean to be human for black people after centuries of dehumanisation? Dr Zuma also looks at the role of desire and fantasy in the political imagination of post-apartheid South Africa. He describes his developing thought and work as the Philosophical Psychology of Black Existence.

Dr Zuma will act as respondent to Judge Sachs’ public lecture, ‘Sites of memory, sites of conscience’ [Hannes, please link to the article on the main website]. This lecture will form part of a series that focuses on how the creative arts represent trauma and memory – and how these representations may ultimately pave the way to healing historical wounds.

Vice-Chancellor’s Lecture Series on Trauma, Memory, and Representations of the Past

This lecture will launch of the Vice-Chancellor’s Lecture Series on Trauma, Memory, and Representations of the Past. It forms part of a five-year research project led by Prof Pumla Gobodo-Madikizela [], funded by the Mellon Foundation []. The event is hosted by the UFS Trauma, Forgiveness and Reconciliation Studies [].

Dr Zuma lives by the belief that, if he imparts what he learns and knows lovingly and creatively, the world will be the better for it.
