Social media discussions have provided a lens on how people are dealing with and talking about COVID-19. This has given risk communication new insights into online audiences.

The lingering effects of the COVID-19 pandemic on society presented the experts at the University of the Free State (UFS) with an opportunity – to conduct a scientific study by analysing our social media data in order to assist government health communicators to reflect on their communication strategies and, in turn, gain new perspectives from the general social media user (public). 

The study – led by Herkulaas Combrink, a data and medical scientist in the UFS initiative for Digital Futures, and Prof. Katinka de Wet, medical sociologist in both the UFS initiative for Digital Futures and the Department of Sociology at the UFS – uses “real-time snapshots of online interactions as a means to augment more traditional methods of conducting research on a given topic; in this case, responses to COVID-19”, said Combrink. 

The findings and ongoing work of the research project were presented to the Parliamentary Portfolio Committee on Communications. “During this meeting, critical engagement took place around risk communication and areas where we can strengthen this research,” said Combrink. Several international influential risk communicators on the African continent were present. 

Digital science at the forefront 

The opportunity to pursue this study was the result of Herkulaas Combrink’s secondment to the Free State Department of Health (FSDOH), where he identified the need to develop additional analytics for the already existing processes in risk communication in order to assist various communication strategies linked to developments regarding COVID-19 infections.  

Combrink also said “because the analysis of social media data does not normally form part of the traditional toolbox of investigation for this type of work, this novel application serves as an addition to the already existing communication analytics”. This research project will strengthen the level of cooperation between the UFS, other institutions, and the FSDOH to “synergistically strengthen communication strategies in relation to COVID-19”. 

By looking at how new knowledge around COVID-19 is developing the method (of analysing social media data), is to stay abreast of trending and burning issues on open-source social media platforms. “It is important to conduct this work using well-defined scientific methodology to extract, explore, analyse, and report on the data,” Combrink says. 

Given the rapidity with which new knowledge around COVID-19 is developing all over the globe, this method lends itself to staying abreast of emergent and burning issues that are trending on open-source social media sites. 

Variety of stakeholders needed

The magnitude of the research study required the involvement of stakeholders from different institutions. “A variety of stakeholders from different institutions are needed not only to contextualise the data, but also to provide social and technical input to solve the problem,” Combrink said.  

Experts included in the project are Dr Vukosi Marivate from the Department of Computer Science at the University of Pretoria, Dr Ming-Han Mothloung from the Department of Community Health at the UFS and the FSDOH, and Dr Samuel Mokoena, Priscilla Monyobo, Mondli Mvambi, and Elke de Witt from the FSDOH. “Without this core team, the work would not have been contextually relevant,” Combrink said.

An astrophysics pioneer at Kovsies

Prof Pieter Meintjes

Over the last decade Prof Pieter Meintjes’ strong background in astrophysics led to the development of a course of excellence at the University of the Free State.

Today we present an Astrophysics degree at our university, from first-year courses to PhDs.

Meintjes matriculated at the Sybrand van Niekerk High School in Sabie and completed a BSc in Physics and Mathematics at the North-West University in 1988. In 1990 and 1993 he respectively obtained his MSc and PhD in Physics from the same university.

Hereafter he spent a post-doctoral year at the Max Planck Institute for Space Science near München in Germany. In January 1997, Meintjes was appointed as a senior lecturer at our university’s Department of Physics. He was promoted to Professor in Physics in 2008.

Prof Meintjes is a member of the South African Institute for Physics (SAIP) and during 2002-2004 he was also co-chair of the astrophysics and space science group of SAIP. He serves on the executive committee of the National Astrophysics and Space Science Programme (NASSP) and is often a visiting lecturer at the University of Cape Town. He is a NRF-supported researcher and author and co-author of 70 publications in high-profile international journals and published conference issues.

During 2011-2013 he successfully delivered three PhD students along with one MSc student. His PhD students also delivered addresses at international conferences in Champery (Switzerland), Heidelberg (Germany), Paris (France), Barcelona (Spain) and Milan (Italy), Cape Town and the Kruger Game Reserve.

Over the last two years he has also been the author and co-author of six publications in Monthly Notices of the Royal Astronomical Society (MNRAS), as well as various publications in the Astrophysical Journal in support of the international planet search programme. A further 12 publications also came forth from Meintjes’ international conference contributions.

During the recent H.E.S.S. meeting in Namibia, Meintjes was appointed as the latest member of the highly-regarded international cooperation with H.E.S.S.

His membership of the H.E.S.S. group is due to his knowledge on gamma rays, which entails research on high-energy astrophysics.
