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.

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability

The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
