This study contributes to knowledge and information sharing and debates on cybersecurity.The objective was to analyse the impact of cybercrimes on the global economy at a time when the whole world is focused on fighting and minimising the spread of COVID-19. The study also analysed common cybersecurity threats, attacks and information systems security vulnerabilities during the period of the pandemic.

    Remediating Sub-Saharan airline challenges and limitations
    (AOSIS, 2022) Leitch, Guy D.; Chigada, Joel
    Air transport connectivity to and within Africa is provided by both African and non-African airlines. These carriers are confronted by both intrinsic and extrinsic challenges, which constrain their ability to provide the level of air transport connectivity demanded to fully enable economic growth for the continent. In addition, since April 2020, the reduction in air connectivity resulting from the coronavirus disease 2019 (COVID-19) pandemic has further constrained the capacity of the air transport industry to meet the passenger and freight demand.

    Secondary school teachers’ perceptions of BYOD among learners within the classroom
    (South African Institute of Computer Scientists and Information Technologists, 2022) Mawere, Talent; Manjeese, Caleb; Chigada, Joel
    The use of personally owned devices among learners has remained a contentious issue in schools across the globe. While several studies have been devoted to explaining the importance of such initiatives, the debate has continued to rage on, with most school authorities imposing a blanket ban on the use of these devices within their premises. In this study, we seek to contribute by examining in-service teachers’ perceptions of the use of personally owned devices in schools within the global south context. The qualitative study explores teachers’ understanding of the usefulness of technology and associated devices such as smartphones in the classroom.
