Digital Scholarship Centre DSC
The recently established Digital Scholarship Centre (DSC) at the UFS is playing an important role in contributing to the development of a collaborative research culture at the university.

The recently established Digital Scholarship Centre (DSC) at the University of the Free State (UFS) is playing a pivotal role in contributing to the development of a collaborative research culture at the university – from cross-faculty and international collaboration to support and administrative services for research.

The DSC was established after an investigation by the Library and Information Services (LIS) to determine the need for digital scholarship support in order to help escalate research output and quality and to support the institutional strategic aim of being a research-led university. The investigation clearly revealed that digital scholarship services would have a significant impact on the UFS' strategic purposes.

Cornelle Scheltema-Van Wyk, Manager of the DSC, says the centre is there to help increase research output, research visibility and impact, and ultimately, the reputation of the university as a research-led institution. “And we do this within the digital scholarship environment (which exists because of digital technology, the internet, and open scholarship), providing researchers with support to use digital methods to enhance their work,” says Scheltema-Van Wyk. 

A pilot project for the DSC was run last year by a work group consisting of representatives from LIS, the Directorate of Research Development (DRD), and ICT Services. An acting manager was appointed, and a web presence was created for the DSC. 

Assistance for researchers
It was clear from the investigation that the research community at the university needed help navigating the digital landscape, determining what services and support systems exist, and how to find, access, and use them. The investigation revealed that researchers are looking for
  • a one-stop shop for research support;
  • increased awareness of services at the university;
  • information, guidance, and training for researchers to enable them to discover, request, and use research support services and digital technologies;
  • creating a strong online presence, while also providing a physical hub with equipment that many researchers cannot afford, as well as a ‘haven’ with an ‘inspiring atmosphere’ to do research when offices become too distracting due to administrative tasks and students;
  • assistance with creating and using collaborative online environments for collaborative research projects;
  • assistance with the open science environment, specifically with regard to open access publishing, funding for open access publishing, and open methods in research; and
  • support for research data management, specifically the development of a research data policy and a data repository at the university.

The centre, which has its roots in the digital, open, and networked environment, also helps to maximise the effectiveness of scarce and limited resources by minimising duplication, not only in research practice with the help of research data management, for example, but also at support level with knowledge of the institutional research environment and where resources can be shared. DSC works to maintain awareness of all relevant resources and can assist with connection and coordination. It also provides information, guidance, training, support services for digital scholarship as well as technology and software, consultation, spaces, and referrals to services such as high-performance computing. 

According to Scheltema-Van Wyk, the benefit of digital scholarship services with a main hub to act as coordinator and consolidator is that the hub has a wider view of the research environment at the institution throughout the research cycle. This includes the planning stages of a research project where a researcher needs to acquire equipment, to data collection and analysis in a digital world, to the preservation of research, and publication in a new scholarly communication environment.

The pilot projects

The UFS has a good foundation of capabilities when it comes to existing research support services for digital scholarship and has developed these capabilities over the past ten years. This includes the High-Performance Computing unit in ICT Services, innovation support by the DRD via KovsieInnovation, and digitisation, digital collections infrastructure, electronic publishing, and repository services at LIS. These support services are very successful from a production standpoint, but the success of visibility and engagement with these services at the institution is more varied.

“The pilot projects illustrated the benefits of the DSC, where researchers were able to contact the centre with questions ranging from how to install research software on their computers, the process of acquiring mobile applications for research purposes (the DSC liaised with Finance to create a process), to setting up online academic seminars and getting third-party applications to work with university resources,” says Scheltema-Van Wyk. 

The knowledge gained from these service requests has already provided the DSC with a broader knowledge of the research environment at the university and allowed recommendations for collaboration and the sharing of resources and expertise in the community.

The DSC uses a hub-and-spoke service model. This model includes a strong central node that links to many other resources. Knowledge, expertise, staff, and services are embedded in academic departments, interdisciplinary units (for example, the newly established Interdisciplinary Centre for Digital Futures), libraries and other service points around the university, which are connected and coordinated through this central node.

The advantage of this model is that it allows growth to take place organically. Services and expertise develop where needed, rather than researchers depending on a centralised unit that may lack the resources to meet ever-evolving digital scholarship needs. Distributed knowledge and skills, however, make it difficult to identify where to go for specific services, training, and assistance. The DSC as a central hub combats the confusion this may cause, linking to the various spokes at the institution.

Prof Corli Witthuhn, Vice-Rector: Research and Internationalisation, says the DSC is at the forefront of providing support to our world-leading researchers on the latest developments in the digital research arena. We are committed to continuing our cutting-edge support and novel approaches to developing the UFS as a research-led university.

Research eradicates bacteria from avocado facility

“The aim of my project was to identify and characterise the contamination problem in an avocado-processing facility and then to find a solution,” said Dr Amy Strydom, postdoctoral fellow in the Department of Microbial Biochemical and Food Biotechnology at the University of the Free State (UFS).

Her PhD, “Control of Listeria monocytogenes in an Avocado-processing Facility”, aimed to identify and characterise the contamination problem in a facility where avocados were processed into guacamole. Dr Strydom completed her MSc in food science in 2009 at Stellenbosch University and this was the catalyst for her starting her PhD in microbiology in 2012 at the UFS. The research was conducted over a period of four years and she graduated in 2016. The research project was funded by the National Research Foundation.

The opportunity to work closely with the food industry further motivated Dr Strydom to conduct her research. The research has made a significant contribution to a food producer (avocado facility) that will sell products that are not contaminated with any pathogens. The public will then buy food that is safe for human consumption.


What is Listeria monocytogenes?

Listeria monocytogenes is a food-borne pathogenic bacterium. When a food product is contaminated with L. monocytogenes, it will not be altered in ways that are obvious to the consumer, such as taste and smell. When ingested, however, it can cause a wide range of illnesses in people with impaired immune systems. “Risk groups include newborn babies, the elderly, and people suffering from diseases that weaken their immune systems,” Dr Strydom said. The processing adjustments based on her findings resulted in decreased numbers of Listeria in the facility.

The bacteria can also survive and grow at refrigeration temperatures, making them dangerous food pathogens, organisms which can cause illnesses [in humans]. Dr Strydom worked closely with the facility and developed an in-house monitoring system by means of which the facility could test their products and the processing environment. She also evaluated bacteriophages as a biological control agent in the processing facility. Bacteriophages are viruses that can only infect specific strains of bacteria. Despite bacteriophage products specifically intended for the use of controlling L. monocytogenes being commercially available in the food industry, Dr Strydom found that only 26% of the L. monocytogenes population in the facility was destroyed by the ListexP100TM product. “I concluded that the genetic diversity of the bacteria in the facility was too high and that the bacteriophages could not be used as a control measure. However, there is much we do not understand about bacteriophages, and with a few adjustments, we might be able to use them in the food industry.”

Microbiological and molecular characterisation of L. monocytogenes

The bacteria were isolated and purified using basic microbiological culturing. Characterisation was done based on specific genes present in the bacterial genome. “I amplified these genes with polymerase chain reaction (PCR), using various primers targeting these specific genes,” Dr Strydom said. Some amplification results were analysed with a subsequent restriction digestion where the genes were cut in specific areas with enzymes to create fragments. The lengths of these fragments can be used to differentiate between strains. “I also compared the whole genomes of some of the bacterial strains.” The bacteriophages were then isolated from waste water samples at the facility using the isolated bacterial strains. “However, I was not able to isolate a bacteriophage that could infect the bacteria in the facility.
