Grey Literature usage in Software Engineering undergraduate research
(Faculty of Science, University of Kelaniya Sri Lanka, 2022) Diyasena, P. H. D.; Wickramarachchi, W. A. P. S.; Arambepola, S. N. M. N. D. K.
The Grey Literature (GL) is a common and popular information source among the Software Engineering (SE) research community. The exponential growth of SE practitioners has led to a rapid increase in GL availability. However, the contribution of GL to SE research is still a little-known fact. In this study, we analysed how SE undergraduates of a Sri Lankan state university use GL in their final year research project. For example, awareness of GL, purposes of using GL, types of GL that they use, and pros and cons related to GL were investigated in this study. An online questionnaire was distributed among SE undergraduates who had recently completed their final year research. Students were asked to complete 12 close-ended questions about GL usage. For further analysis, a convenience sample of 70 responses from final-year SE undergraduates was selected. A quantitative data analysis approach was followed to analyse the responses. To our knowledge, this is the first study considering undergraduate GL usage in the SE community. As per the responses collected, they have conducted various types of research, e.g., original research (52.9%) and systematic literature reviews (14.3%). However, most of them have utilized GL while unaware of the term “Grey Literature.” Since this study specifically focuses on the students who have accessed GL, 45 responses were taken for further analysis. Among those, 44.3% of students cited more than five GL sources as references. According to the results, we identified that web articles were the most used type of GL (82.2%) and the least used GL type was News articles or magazines (28.8%). Apart from that, popular platforms such as Medium Blogs and YouTube have been used as the main sources of GL. Among the respondents, GL was mainly used to find related studies (73.3%) and to create the research problem (62.2%). Further, we identified ease to access (86.7%) as a significant benefit and unreliability (60%) as a major challenge when using GL. These results indicate that, GL plays an important role in acquiring knowledge about current SE challenges and technologies for SE researchers due to the rapid change in technology and the lack of updated publications. The findings of our study provide better insights into the usage and significance of GL in undergraduate SE research while contributing to the SE research community.
A way forward for Sustainable Human-Computer Interaction
(Faculty of Science, University of Kelaniya Sri Lanka, 2022) Arambepola, S. N. M. N. D. K.; Munasinghe, L.
Sustainability has become a buzzword in the modern world. In fact, the United Nations (UN) has proposed seventeen Sustainable Development Goals (SDG) to achieve by 2030. SDG can be achieved through different approaches. As modern society is moving forward with a digital world through novel technologies, one promising way of achieving SDG is Sustainable Human-Computer Interaction (SHCI). SHCI is a relatively new research area that is trying to address sustainability issues mainly through sustainable social transformation. Thus, we conducted this research with two main objectives. 1) To analyse how Human-Computer Interaction (HCI) researchers have contributed to this evolving research area 2) To find further opportunities to address sustainability issues using HCI designs. Then finally, we suggested novel approaches to address sustainable energy goals through technological device usage. At the initial stage, research articles were collected through mainly five (05) databases: Google Scholar, IEEE Xplore, Scopus, ACM Digital Library, and ResearchGate. There, keywords such as "Sustainable HCI", "Sustainable Human-Computer-Interaction", "Sustainable interaction design" and "SHCI" were used for collecting research papers through keyword-based filtering. In addition, other research papers were collected through the references of the selected most cited papers. We considered research papers published in top-ranked HCI research conferences and journals for this review. The total collected number of 56 research articles was filtered through the inclusion and exclusion criteria of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method. Out of 30 papers, most of the articles were published in 2014 and 2015. The bibliographic results show a decrease in SHCI research publications after 2015. According to the findings, SHCI can be achieved mainly through Sustainable Interaction Design (SID). There are two main categorizations of SID. 1) Sustainability in design 2) Sustainability through design. "Sustainability in design" aims to find solutions to social, economic, and environmental issues in our own design, implementation, and evaluation practices. For example, "Affordable and Clean Energy" can be achieved by reducing the energy consumption of the computerized machines used in our daily routines. For instance, introducing lightweight mobile apps can be a successful move for reducing data usage and energy consumption in daily-using mobile apps as a suggestion aligned with the identified opportunities for future development. "Sustainability Through Design" means designing interactive products that promote the sustainable behaviour of its users. For instance, we can consider designing mobile applications as a tool for awareness and encouraging behavioural changes favouring sustainability. One of the key findings of this study is that “sustainable energy” is the specific area that most researchers have addressed through SHCI. The results of this study are beneficial for researchers in different disciplines, such as HCI, sustainability, digital technology, and interaction designs, to contribute to sustainability by reducing energy consumption.
