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.

The field of Nuclear Medicine in South Africa and the rest of the world are expanding rapidly due to the development of hybrid cameras and new radiopharmaceuticals. These developments have a huge impact on the diagnosis and therapy of cancer.

The most advanced of these cameras, Positron emission tomography combined with normal CTs (PETCT), are not yet widely available in South Africa due to the cost of the cameras and the radiopharmaceuticals. A more cost-effective alternative can be of great benefit. To achieve this, the focus should be on developing new radiopharmaceuticals that can be used with the current cost-effective gamma cameras, according to University of the Free State researcher, Dr Je’nine Horn-Lodewyk from the Department of Nuclear Medicine.

Fluorodeoxyglucose (18F-FDG), a radiolabelled glucose analogue, is currently the radiopharmaceutical most commonly used in PET/CT imaging for mainly oncology indications. Although it is considered the gold standard for imaging in several malignancies, it does have certain disadvantages. An 18F-FDG PET/CT diagnostic imaging study can cost between R25 000 and R35 000 for a single patient in the private sector. The 18F-FDG is also more radioactive, which requires much stricter handling and shielding to avoid high radiation dosages to staff and patients.

Successful research potential innovative solution
In the search for the ideal radiopharmaceutical for tumour detection, the South African National Nuclear Energy Corporation (Necsa) developed a local synthesis process for ethylenedicysteine-deoxyglucose (EC-DG). EC-DG is also a glucose analogue similar to FDG. They succeeded in labelling the compound with Technetium-99-metastable-pertechnetate (99mTcO4-), the most common nuclear medicine isotope used for approximately 95% of nuclear medicine procedures, creating 99mTc-EC-DG.

In partnership with Dr Horn-Lodewyk, this compound was successfully used in various animal models and clinical scenarios, resulting in approval by the Medicine Control Council to use it in a human study. Research is also planned in order to investigate diagnostic accuracy in other cancers like lymphoma.  The end result of this research can produce a radiopharmaceutical that is cost effective, does not require the use of costly specialised equipment, has no significant side-effects, no special patient preparation, renders late imaging possible, and has decreased radiation risks.

Dr Horn-Lodewyk is grateful for the support of her mentor, Prof Anton Otto, as well as Dr Gert Engelbrecht, Head of the Department of Nuclear Medicine, Prof Jan Rijn Zeevaart from North-West University’s Preclinical Drug Development Platform and Necsa, and Judith Wagener from Necsa. This innovative research would also not have been possible without the financial assistance of Dr Glen Taylor and Eleanor van der Westhuizen in the Directorate of Research Development.
