    In-lecture media use and academic performance : investigating demographic and intentional moderators
    (South African Institute of Computer Scientists and Information Technologists, 2018) Parry, Douglas A.; Le Roux, Daniel B.
    The growing prevalence of continuous media use among university students in lecture environments has potential for detrimental effects. In this study we investigate the relationships between in-lecture media use and academic performance. Previous studies have shown that students frequently engage with digital media whilst in university lectures. Moreover, multitasking imposes cognitive costs detrimental to learning and task execution. We propose, accordingly, that the constant distractions created by digital media, interrupt the thought and communication processes of students during lectures and, subsequently, obstruct their ability to learn. To test this proposition we conducted a survey-based empirical investigation of digital media use and academic performance among undergraduate university students. A significant negative correlation was found between the number of in-lecture media use instances and academic performance. Furthermore, this effect was found to be pervasive independent of individual demographic factors and the intention with which a medium was used.

    Working in a post Covid-19 world : towards a conceptual framework for distributed work
    (AOSIS, 2019) Henry, Michael S.; Le Roux, Daniel B.; Parry, Douglas A.
    Purpose: Against the backdrop of the increased prevalence of telework practices as a result of Covid-19, the purpose of the present article is to address the conceptual confusion, overlap and ambiguity characterising much of the published literature in this domain through the development of an integrated conceptual framework describing distributed work practices at various levels of organisations. Design/methodology/approach: To develop the framework, a collection of definitions for distributed work concepts were systematically selected and reviewed. These concepts include telework, remote work, distributed work and virtual work, as well as telecommuting, virtual teams, virtual organisations and distributed organisations. The reviewed definitions were systematically analysed to elicit the key principles underlying each concept, and then integrated to produce the conceptual framework. Findings: Our analysis suggests that virtuality and distributedness can be defined as distinct continua which, when combined, can be used to describe particular work settings. Additionally, we identify four factors which impact organisational policy in terms of virtuality and distributedness: interdependence of tasks, nature of work, technological environment and temporal distance. Practical implications: The framework offers managers a foundation for establishing distributed work policies and determining policy implications. Additionally, researchers conducting empirical investigations of distributed work practices can utilise the framework to differentiate between and describe particular work settings. Originality/value: The conceptual integration of virtuality, distributedness and organisational levels present a novel and important development. As organisations adapt to the effects of the Covid-19 pandemic, the framework we propose serves as a useful artefact to support and inform their decision making.
