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.

Schae-Lee Olckers, a master’s student in the Department of Microbial Biochemical and Food Biotechnology at the University of the Free State (UFS), will be travelling to the US in a few weeks’ time. For the next two years she will be doing research at the Michigan State University (MSU) at its Department of Food Science, working on wheat quality and its baking properties.

Increase the nutritional value of maize
The title of her master’s research project is: “The influence of low and optimal nitrogen conditions on the nutritional value of quality protein maize”. She is focusing on the influence of environmental conditions on the nutritional value of maize.

New hybrids of maize production developed

Olckers said: “I chose to start my research on this specific topic in my honours year because maize is the main staple crop in South Africa, as well as in the rest of Africa. Therefore, micronutrient malnutrition is a major concern for developing countries as well as for poor people who rely on it as a major food source. I found it interesting that these breeding programmes that are being developed for new hybrids of maize for production are focusing on increasing the nutritional value of maize and can therefore help eliminate micronutrient malnutrition in some populations of poor communities,” she said.

Prof Perry Ng will be her research supervisor. He is an affiliated professor at UFS in the division of Plant Breeding. “I am very excited about the opportunity to travel and to gain experience working with a well-known cereal scientist. The work he does is also closely associated with my research,” said Olckers.

Her supervisors at UFS are Profs Garry Osthoff and Maryke Labuschagne from the Departments of Microbial Biochemical and Food Biotechnology and Plant Sciences respectively.
