When Dr Rouxan Fouché decided to undertake a PhD in Computer Science and Informatics, he was motivated by his commitment to addressing the digital divide in South Africa through service-learning. Through his research, he investigated how the UFS’s Information Technology Service-Learning (ITSL) project could be improved by collaboration with all project stakeholders to positively address and impact the digital divide in the local Mangaung community.

Dr Fouché is a lecturer in the Department of Computer Science and Informatics at the University of the Free State (UFS) and received his PhD during the UFS’s April 2023 graduation ceremonies. 

He based his PhD thesis, titled ‘Addressing the South African Digital Divide through a community-informed strategy for Service-Learning: A Critical Utopian Action Research (CUAR) Approach’, on the service-learning module he taught after he realised the positive effect of an information technology-focussed service-learning module on computer literacy levels in the local community. “The initial goal of the service-learning module was to provide free computer literacy training to computer-illiterate community members as part of the students’ community engagement,” Dr Fouché said. 

Community-focused PhD research

According to Dr Fouché researchers have recently started looking at how universities can use their service-learning modules (as part of community engagement) to bridge and address the digital divide. He also believes “current conceptualisations indicate that most university service-learning endeavours are organised without engaging with the local community or incorporating their specific needs.”

This is where he hopes his research and findings could make a difference.

His study aimed to re-evaluate and revise the ITSL project by using a hands-on, collaborative approach which included all ITSL project stakeholders. Members of the community served by the project were involved in the shared decision-making and knowledge sharing. “Furthermore, the short-term and lasting impacts of this revised community needs-led ITSL project on the participating community members were investigated.” 

The study was conducted in three cycles: Cycle 1 constituted a survey approach to identify the concerns and possible shortcomings of the ITSL project. In Cycle 2, all stakeholders participated in a ‘Future-Creating Workshop’, which reviewed findings from Cycle 1, and a utopian action plan was developed by all involved. Cycle 3 saw the revised project being implemented based on all the recommendations from the previous cycle. “This cycle also included the evaluation of the project’s immediate impact using pre-test and post-test questionnaires completed by project participants.” 

Service-learning project made a difference

When Dr Fouché initiated the ITSL project in 2015, the main objective was to serve and equip Mangaung and surrounding communities with necessary computer literacy skills. The programme entails training in Microsoft Word and Excel via two short learning programmes.

The impact of the programme was far-reaching, as it enabled participants to gain formal employment. “The participants told me that they were able to find employment as service station attendants, administrative clerks, and cashiers, among other roles, due to the computer literacy certificates they received after completing the ITSL project.” Witnessing the positive impact of the ITSL programme led Dr Fouché to focus his PhD research on improving the service-learning offerings the UFS provides for the community. 

“I realised that it was necessary to investigate how the ITSL project could be improved and tailor-made for the community it serves,” he said.

In August 2017, the Boyden Observatory in Bloemfontein played a major role in obtaining optical observations of one of the biggest discoveries ever made in astrophysics: the detection of an electromagnetic counterpart to a gravitational wave event.
 
An article reporting on this discovery will appear in the prestigious science journal, Nature, in October 2017. Co-authors of the article, Dr Brian van Soelen and Hélène Szegedi, are from the Department of Physics at the University of the Free State (UFS). Both Dr Van Soelen and Szegedi are researching multi-wavelength astronomy.
 
Discovery is the beginning of a new epoch in astronomy
 
Dr van Soelen said: “These observations and this discovery are the beginning of a new epoch in astronomy. We are now able to not only undertake multi-wavelength observations over the whole electromagnetic spectrum (radio up to gamma-rays) but have now been able to observe the same source in both electromagnetic and gravitational waves.”
 
Until recently it was only possible to observe the universe using light obtained from astronomical sources. This all changed in February 2016 when LIGO (Laser Interferometer Gravitational-Wave Observatory) stated that for the first time they had detected gravitational waves on 14 September 2015 from the merger of two black holes. Since then, LIGO has announced the detection of two more such mergers. A fourth was just reported (27 September 2017), which was the first detected by both LIGO and Virgo. However, despite the huge amount of energy released in these processes, none of this is detectable as radiation in any part of the electromagnetic spectrum. Since the first LIGO detection astronomers have been searching for possible electromagnetic counterparts to gravitational wave detections. 
 
Large international collaboration of astronomers rushed to observe source
 
On 17 August 2017 LIGO and Virgo detected the first ever gravitational waves resulting from the merger of two neutron stars. Neutron star mergers produce massive explosions called kilonovae which will produce a specific electromagnetic signature. After the detection of the gravitational wave, telescopes around the world started searching for the optical counterpart, and it was discovered to be located in an elliptical galaxy, NGC4993, 130 million light years away. A large international collaboration of astronomers, including Dr Van Soelen and Szegedi, rushed to observe this source.
 
At the Boyden Observatory, Dr Van Soelen and Szegedi used the Boyden 1.5-m optical telescope to observe the source in the early evening, from 18 to 21 August. The observations obtained at Boyden Observatory, combined with observations from telescopes in Chile and Hawaii, confirmed that this was the first-ever detection of an electromagnetic counterpart to a gravitational wave event. Combined with the detection of gamma-rays with the Fermi-LAT telescope, this also confirms that neutron star mergers are responsible for short gamma-ray bursts.  
 
The results from these optical observations are reported in A kilonova as the electromagnetic counterpart to a gravitational-wave source published in Nature in October 2017.
 
“Our paper is one of a few that will be submitted by different groups that will report on this discovery, including a large LIGO-Virgo paper summarising all observations. The main results from our paper were obtained through the New Technology Telescope, the GROND system, and the Pan-STARRS system. The Boyden observations helped to obtain extra observations during the first 72 hours which showed that the light of the source decreased much quicker than was expected for supernova, classifying this source as a kilonova,” Dr Van Soelen said.
