Dr Rouxan Fouche — Dr Rouxan Fouché on stage in the Callie Human Centre during his graduation ceremony. He hopes his PhD findings will be used to improve the UFS’s Information Technology Service-Learning (ITSL) project’s effectiveness.

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 future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
