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.

UFS study on cell development in top international science journal
2008-09-16

A study from the University of the Free State (UFS) on how the change in the packaging of DNA with cell development influenced the expression of genes, will be published in this week’s early edition of the prestigious international, peer-reviewed science journal, the Proceeding of the National Academy of Sciences of the USA (PNAS).

The PNAS journal has an impact factor of 10, which means that studies published in the journal are, on average, referred to by ten other scientific studies in a two year period. The South African Journal of Science, by comparison, has an impact factor of 0.7.

The UFS study, funded by the Wellcome Trust and the National Research Foundation (NRF), looked at how the change in the packaging of DNA with cell development influenced the expression of genes. It is very relevant to research on stem cells, an area of medicine that studies the possible use of undifferentiated cells to replace damaged tissue.

Prof. Hugh Patterton, of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, who led the study, said: "We are extremely proud of this study. It was conceived in South Africa, it was performed in South Africa, the data were analysed in South Africa, and it was published from South Africa."

When a gene is expressed, the information encoded in the gene is used to manufacture a specific protein. In eukaryotes, which include humans, there is approximately 1m of DNA, containing the genes, in every cell. This length of DNA has to fit into a cell nucleus with a diameter of only about 10 micrometer. In order to fit the DNA into such a small volume, eukaryotic cells wrap their DNA onto successive protein balls, termed nucleosomes. Strings of nucleosomes, resembling a bead of pearls, is folded into a helix to form a chromatin fiber. The study from the UFS investigated how the binding of a specific protein, termed a linker histone, that binds to the length of DNA between nucleosomes, influenced the formation of the chromatin fiber and also the activity of genes.

"We found that the linker histone bound to chromatin in yeast, which we use as a model eukaryote, under conditions where virtually all the genes in the organism were inactive. It was widely believed that the binding of the linker histone caused the inactivation of genes. We studied the relationship between the amount of linker histone bound in the vicinity of each gene and the expression of that gene for all the genes in yeast, using genomic techniques. We made the surprising discovery that even through the linker histone preferentially bound to genes under conditions where the genes were shut off, this inactivation of genes was not caused by the binding of the linker histone and folding of the chromatin,” said Prof. Patterton.

He said: “Instead our data strongly suggested that the observed anti-correlation was due to the movement of enzymes along the DNA molecule, involved in processing the information in genes for the eventual manufacture of proteins. This movement of enzymes displaced the linker histones from the DNA. This finding now requires a rethink on aspects of how packaging of DNA influences gene activity."

Prof. Patterton said that his research group, using the Facility for Genomics and Proteomics as well as the Bioinformatics Node at the UFS, was currently busy with follow-up studies to understand how other proteins in nucleosomes affected the activities of genes, as well as with projects to understand how chemicals found in red wine and in green tea extended lifespan. "We are certainly having a marvelous time trying to understand the fundamental mechanisms of life, and the UFS is an exciting place to be if one was interested in studying life at the level of molecules," he said.
