    Leveraging Social Media in Higher Education: A Case of Universities in Uganda
    (European Journal of Open, Distance and E-learning, 2019) Mirembe, Drake Patrick; Lubega, Jude T.; Kibukamusoke, Martha
    Social media platforms have transformed the way we live and work. These platforms have opened up new opportunities for service provisioning and business models. Therefore, this paper presents findings of how leading Ugandan Universities are integrating social media in the teaching and learning processes. The researchers adopted a multi-methodology research approach which involved; collecting, analysing and integrating quantitative (surveys) and qualitative (focus group discussions and interviews) research methods. A total of 300 respondents were targeted (students and lecturers) of which 250 responded (196 male and 54 female). The respondents from Makerere University, Uganda technology and Management University (UTAMU) and Makerere University Business School. The results of the study indicated that majority (94.8%) of the respondents use WhatsApp, 86.5% Facebook, 82.1% YouTube, 53.8% Twitter, 39.8% Instagram and 9.2% snapchat. It was observed that 225 about 91.1% of student’s use social media for learning purposes. A total of 238 respondents use smartphones to access social media. While majority of students on social media platforms use these platforms for learning purposes, majority of lecturers (37.6%) never engage students on social media. Therefore, there is a mismatch on social media usage between students and lectures and this calls for the development of social media policies at universities to promote and guide the integration of these platforms in the teaching and learning processes.

    Scaling Trust and Reputation Management in Cloud Services
    (International Journal of Applied Science and Technology, 2016) Nyabisa Oteyo, Isaac; Mirembe, Drake Patrick; Nampala, Paul
    Trust and reputation (TR) are critical considerations in the adoption of cloud services. However, there are challenges in managing TR among cloud service providers that trickle down to the service requesters. The trends used currently for TR management are ad hoc and mostly driven by need and different approaches for representing TR management in cloud services have been proposed. A hybrid of the various methods and models yields a near optimal solution for TR management in cloud services. The hybrid can be constructed from the pool of TR management options for cloud services, the different technologies applied in cloud management, and the impact factors for the different categories of cloud services. These technologies and categories of cloud services are presented in this paper. With the increased use of cloud services, there is an urgent need for explicit institutional arrangements that will help in monitoring and regulation to secure TR in cloud computing platforms and environments.

    A usability based approach to designing continuous user biometric authentication system
    (Quality and User Experience, 2018) Mugambi Kaburu, Dennis; Sansa‑Otim, Julianne; Mayanja, Kajumba; Mirembe, Drake Patrick; Bulega, Tony
    Abstract The advent of the internet and associated technologies have revolutionized the way we live and work. Today, organizations both public and private rely heavily on information systems to deliver services. The quality and reliability of services delivered by these systems depends on controlled access to these information systems. In mission, critical systems like online examination and military intelligence, there is need to verify constantly the identity of the user throughout the session of interaction (referred to as “continuous user authentication”). Accordingly, researchers have proposed a number of approaches to address the issues of continuous user authentication. However, these approaches require user collaboration, which affects user performance on the core tasks in the business processes because of user task interruptions. Thus, the approaches have usability challenges. Continuous user Biometric Authentication systems have a usability score of the range 55–60% on a System Usability Scale (SUS) on average, interpreted in SUS score as poor. Therefore, this paper discusses the design of a non-intrusive continuous user biometric authentication approach, which aims at guiding the design of continuous user biometric authentication systems with SUS score above the range of 65% in relation to the context of the primary task in the business process. The cognitive approach proposed incorporates usability quality attribute in respect to the users’ primary tasks on the system by applying results from cognitive psychology. The approach allows a designer to understand the impact of a particular re-authentication method to user performance and satisfaction in a continuous user authentication environment.

    Using ICTs to enhance duty bearer accountability and transparency to citizens in Eastern and Northern Uganda
    (International Journal of Information Technology, Communications and Convergence, 2019) Mirembe, Drake Patrick; Lubega, Jude T.; Kibukamusoke, Martha
    This article explores the use of ICTs to enhance engagement between citizens and leaders in Eastern and Northern Uganda. It highlights how ICT empowers citizens to demand accountability and transparency from leaders. The key objective was to establish the extent to which the use of ICT promoted leaders responsiveness to citizens’ concerns about accountability and transparency. A participatory action research was used through key informant interviews, focus group discussions and survey targeting 180 citizens and leaders. Findings show that nearly 83.1% of the citizens (108 of the 120 who responded to the question) do use ICT to engage duty bearers on government programmes and accountability issues and the most commonly used ICTs by citizens to engage with leaders are mobiles phones (about 83.1%) and radios (64.6%). It was clear that use of ICT does indeed improve leader responsiveness to citizen concerns.
