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.

For the first time in its history, the Department of Consumer Science in the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) earned three doctorates at one graduation ceremony this year. This week three PhDs were awarded to Ismari van der Merwe, Natasha Cronje, and Gloria Seiphetlheng at the Winter Graduation that took place on the Bloemfontein Campus.

Electrochemically-activated water is widely used in the food and other industries, due to its excellent environment-friendly properties. However, it is not used in the textile industry yet, because too little research has been done to determine the possible positive and negative impact it may have on textiles.

With the thesis, The evaluation of catholyte treatment on the colour and tensile properties of dyed cotton, polyester and polyamide 6,6 fabrics,  Dr Cronje, a lecturer in the UFS’s Department of Consumer Science, and Dr Seiphetlheng from the Serowe College of Education in Botswana,  provided major new information with the thesis, Anolyte as an alternative bleach for cotton fabrics. This information is essential when considering the application of catholytes and anolytes in the textile industry.

Electrochemically-activated water divides water in catholytes and anolytes. The anolyte part is used as a disinfectant and bleach. It is not really suitable for domestic use, as it can cause colour loss in coloured textile products. However, it can be used in the hospitality industry where white sheets, towels, etc., are used and washed on a regular basis.

The catholyte part of the water has properties similar to washing powder. It can also be used in the textile industry as washing liquid.

According to Prof Hester Steyn, Head of the Department of Consumer Science and supervisor of all three PhD candidates, this electrochemically-activated water is also very eco-friendly. “It has a short shelf life. If the electrochemically-activated water isn’t utilised, it returns to normal water that wouldn’t harm the environment. No water is therefore lost, and no waste products are released that would contaminate the environment,” she says.

Dr Van der Merwe’s research focused on Degumming Gonometa postica cocoons using environmentally conscious methods. A lecturer in the Department of Consumer Science, she demonstrated that simple and environmentally-friendly methods can be used with great success to procure wild silk from the cocoons of the Gonometa postica worms living in the camel thorn trees found in the Northern Cape and Namibia.
