The aim of this study was to investigate the Usability of Digital Institutional Repositories (DIRs) by faculty and postgraduate (PG) students at the Namibia University of Science and Technology (NUST). The study addressed the major research question: what systems usability factors influence the depositing and use of scholarly content in the DIR?. Specifically the study addressed the following research questions:1) What are the attitudes and perceptions of PG students and faculty towards DIRs?, 2) To what extent are PG students and faculty at NUST: a) archiving their research output in the DIR, b) using content in the DIR?, 3) What is the perceived usefulness of DIR by PG students and faculty?, 4) What is the level of satisfaction of PG students and faculty with DIR? 5), What an extent of system usability of the DIR by PG students and faculty?
The Technology Acceptance Model (TAM) model was used to underpin this study because of its strength and parsimoniousness. A post-positivist approach was used, with a predominantly quantitative and lesser qualitative approach, respectively. Interviews, questionnaire, document review and system observation and expert’s evaluation methods were used for data collection. The study population comprised faculty, PG students, Librarians and a system developer. Quantitative data was analysed using Statistical Package for the Social Sciences (SPSS), while qualitative data was analysed using content analysis. Reliability and validity were achieved through methodological triangulation, pretesting the questionnaires, and careful transcription of the data. The findings revealed lack of the awareness about DIR among PG students and faculty. The findings further revealed weak institutional repository policy which does not clearly stipulate processes and standards on the submission of scholarly works to the repository. Moreover, there seemed to be misconception on the part of faculty and PG students about DIR and open access.
Usability of Digital Institutional repositories and timely access to information through DIRs is a critically important topic, globally, and in Africa, where achieving informed and knowledge society is a prime goal. The provision of such access is predicated on well-designed DIR platforms and effective disseminated information through these systems.
This study investigated systems usability factors influencing the depositing and use of scholarly content in the DIRs by faculty and postgraduate students at the Namibia University of Science and Technology respectively. Although Namibia university of technology has established the digital institutional repository, there has not been a study carried out to investigate and evaluate the use and the usability of the system, to mitigate and adapt to latest technology trends and variability and improve the DIR functionality. This study therefore was conducted to monitor and evaluate the use of new knowledge in adapting to climate change and variability and improving agricultural production.
The originality of the study lies in two contexts. First, this study is unique in Namibia, due to the fact that, despite investment on projects in development of new technology and innovation which aims to ensure the long term preservation of scholarly communication and open access in academic libraries, no research has been done in the area to monitor and evaluate the use of content and the usability of these systems.
Secondly, the literature reviewed could not identify a related study which had been conducted in Namibia to assess the contribution of information dissemination to enhance adoption of innovations technology such as DIRs. Despite several studies being conducted notably in no study could be found which has explored usability of the Institutional Repositories since the establishment and exploring how information is being disseminated and accessed. This study is therefore expected to build on existing knowledge gaps in existing empirical and theoretical evidence on how digital repositories can be designed to enhance usefulness, effectiveness and ease of use of the system to improve information dissemination in Namibia. The outcome of the study is expected to provide evidence based data upon which relevant academic library institutional repositories policies can be formulated. The study also provides data that would inform budget allocation for ICT infrastructure development for libraries, human resource development and staffing academic public libraries in Namibia. Using the TAM model, the study contributes to literature on the factors that influence the self-archiving and use of information systems such as DIRs in academic libraries from a developing country context. This study also intends to fill the gap in literature especially in regard to self-archiving policies and training required to fulfil the DIRs usability
