  • Research Data Management in a Developing Country: a Personal Journey
    IJDC | General Article Research Data Management in a Developing Country: A Personal Journey Martie van Deventer Heila Pienaar University of Pretoria and CSIR University of Pretoria Abstract This paper explores our own journey to get to grips with research data management (RDM). It also mentions the overlap between our own ‘journeys’ and that of the country. We share the lessons that we learnt along the way – the most important lesson being that you can learn many wonderful and valuable RDM lessons from the international trend setters, but in the end you need to get your hands dirty and get the work done yourself. You must, within the set parameters, implement the RDM practice that is both appropriate and acceptable for and to your own set of researchers – who may be conducting research in a context that may be very dissimilar to that of international peers.

It invited all role players in the national innovation system to rethink their role and to find opportunities to face the challenge of increasing economic growth and improve the quality of life for all South Africans. It was clear that the strategy called for a renewal in the information services sector. It was anticipated that the strategy would require a level of information service support that was not available at any individual institution. One of the challenges, the declining affordability of access to the global research literature, was the initial spur for the establishment of the South African Research Information Services (SARIS) project team endeavour.

  • A CASE of WITS UNIVERSITY Eugenia Sekgobela
    NRENs AS ICT INFRASTRUCTURE TO SUPPORT e-SERVICES AT UNIVERSITIES: A CASE OF WITS UNIVERSITY Eugenia Sekgobela Supervisor: Lucienne Abrahams A research report submitted to the Faculty of Humanities, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree of Master of Arts in the field of ICT Policy and Regulation 2015 Abstract The research report examined the value brought by NRENs, by investigating the utilization of the South African National Research Network (SANReN) at the University of the Witwatersrand (Wits). It explored the SANReN as the main international bandwidth service for the university and assessed how the university is able to efficiently provide a range of e-services in scientific research through the NREN. Wits scientists engaged in data intensive research and international research collaboration shared the view that the SANReN infrastructure is critical to such work, however due to infrastructure limitations at university level, it is sometimes difficult to maximize the value of this dedicated network, where data storage capacity is low. A wide range of e-services, such as grid computing, use SANReN, but are limited by international bandwidth. A further problem is the high cost of international bandwidth, particularly as the demand for bandwidth increases with the amount of data required in scientific research. The biggest challenge is the growth of demand and the ability to meet this demand. As scientific research relies on real time data, but experiences problems with data storage, advanced data infrastructure is needed in the form of a medium sized data centre, which would be used for storing and transferring large data sets and terabytes of data in and out of the country.

  • National Integrated Cyberinfrastructure System a Framework for the Establishment and Maintenance of a Sustainable NICIS
    National Integrated Cyberinfrastructure System A framework for the establishment and maintenance of a sustainable NICIS Report of the International Committee for the Development of South Africa’s National Integrated Cyberinfrastructure System Appointed by the Department of Science and Technology December 17, 2013 NICIS Framework 1 Executive Summary Introduction The impact that cyberinfrastructure has made and can make as a driver in research and development is now well recognised. This point was made in a very strong symbolic way as this report was finalised by the awards of the 2013 Nobel Prizes in Chemistry 1 (which recognised the impact that complex computational models can make in developing Chemistry) “for the development of multiscale models for complex chemical systems” and Physics "for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles, and which recently was confirmed through the discovery of the predicted fundamental particle, by the ATLAS and CMS experiments at CERN's Large Hadron Collider", in which experimental work and a massive worldwide cyberinfrastructure was required to complement the theoretical insight of the awardees. This “third mode of science” is likely to grow in importance. Cyberinfrastructure is critical to the competitive innovation capacity of industry and society for socio-economic benefit, as well as many research areas across all disciplines. e-Science, as a third-mode of science, relies on a strong cyberinfrastructure. The framework for the establishment and maintenance of a sustainable National Integrated Cyberinfrastructure System (NICIS) aims to exploit the enormous synergies that can be derived from integrating national Cyberinfrastructure (CI) into a cluster of mutually supporting activities which leverage high-level financial and strategic planning, as well as oversight and management.
