    A model for the acceptance and use of mHealth in South Africa: A UTAUT and TTF perspective
    (University of the Witwatersrand, Johannesburg, 2023) Livhuwani Grace, Mongwe; Hughes, Mitchell; Kekwaletswe, Ray
    Scaling up high impact community based mHealth interventions is one of the agenda items mentioned in the National Digital Health Strategy of South Africa for the period 2019 -2024. Although many mHealth interventions have been explored, many of them end up in the pilot phase and do not reach full implementation. A common theme which was found as a possible driver of scalability is designing an mHealth application that considers usability and acceptability by users. The purpose of this study was to synthesize a model for the acceptance and use of mHealth in the South African health sector. A positivist research approach was used to test the adoption factors using the Task-Technology Fit (TTF) and the Unified Theory of Acceptance and Use of Technology (UTAUT). Seven factors that could potentially impact the adoption of mHealth technology in South Africa were tested. The data for the study was collected through an online survey questionnaire which was shared through social media platforms. Results of this study were used to answer questions related to factors that have an impact on the adoption of mHealth applications in the health sector in South Africa. The study found that when adoption factors were combined into the UTAUT and TTF model, the only factor that was significant was facilitating conditions. The study findings in this regard were not consistent with other studies and it is therefore recommend that other scholars explore the reasons for these differences. The other factors were found to be significant when bivariate regression was used to compare the factors to the dependant variable of user acceptance and use of mHealth technology. The study further found that the combined model of Task Technology Fit has a positive impact on the adoption of mHealth technology in South Africa. The implication of the finding is that mHealth designers should build the functionalities of the innovation with the idea of making the task that the innovation supports easier to perform

    An expository analysis of the consequential loss (business interruption) policy in light of covid-19 and the UK and SA litigation
    (University of the Witswatersrand, Johannesburg, 2024) Spentzouris, Penelope; Vivian, Robert William
    The consequential loss (CL) usually referred to as the business interruption (BI) policy, although about 120 years old, has, until recently. not been subject to much litigation and therefore has had little benefit of judicial interpretation. On the other hand, it is one of the most complex of non-life policies. Things changed with the Covid pandemic, in that, the BI policy was subject to considerable litigation. About 2 000 cases were filed in the US with the litigation still ongoing at the time of the writing of this dissertation. The South African and UK courts litigated but on a different aspect of the policy, compared to the US. The US litigation involved the main policy whereas the UK and SA involved an extension to the policy. This extension does not form part of the US policies. The UK and SA courts relied largely on general legal principles of interpretation of contracts, applied to insurance contracts, to reach their conclusions. In so doing, the courts in these jurisdictions paid little attention to the context and construction of the BI policy taken as a whole, including the historical reason for its existence. Nor did the courts consider the issue of insurability to any detailed extent. It is also pointed out that the leading text book on this policy does not approach the policy in terms of fundamental principles. This dissertation systematically sets out the history, purpose, structure and interpretation of this policy, restating the policy in terms of its history and purpose. The dissertation sets out the lessons which can be learnt from the Covid-19 litigation. An analysis is made of the main policy and the extensions having regard for the various wordings of the BI policy. Finally, the possibility of developing a BI policy which may respond to a future event of a pandemic is considered

    The Application of Robotics in Deep Level Mining in South Africa and its Influence on Health and Safety
    (University of the Witwatersrand, Johannesburg, 2023) Gaokgorwe, Tebogo; Gobind, Jenika
    Application of robotics in mining operations particularly in deep mining is considered to be challenging when factoring the impact of health and safety in day to day operations. Majority of the employees in South Africa’s mining industry have low training levels, unskilled work content as well as large figures of underground employees labouring for survival at lower-end cost curves and excessive exposure to deprived underground conditions. The rising demand for mineral products is compelling mining companies to go deeper in mines even where such increase in the depth results in higher costs, risks, and a further decline in the conditions of working. This paper examines the current application of robotics in deep level mining, discusses the challenges in robotics adoption and their influence in health and safety. Trusting on the qualitative content analysis methodology the study adopted to interview participants and collect data from the mining journals for sampling and data collection. The findings suggest that although deep-level mines have embraced an increase in robotics and extensive methods due to global competition and the need for better access to mineral reserves trends in productivity in the gold mining industry remains unchanged for a long period and mining labour remains impacted by slow technological advancement. Inadequate application of robotics and developed control policies and measures for dealing with occurring mining disasters are some of the key challenges with the robotics adoption. The application of robotics will allow all safety experts to plan for exploration, extraction, optimisation of operations and worker monitoring as well as protection. The limitations of the study is that there are few current publications peer reviewed articles and the prevailing literature is old for the current research. The study concludes that there is a gradual advancement of technical capacities in deep-level mining. The main technical challenges to the application of robotics is the availability, reliability as well as fail-safe operations of robotics. Lastly robotics will improve exploration, mapping of mining operations as well as worker equipment. The study recommends future studies on comprehensive approaches to the socio-economic effect of robotics mechanisation and application in deep-level mining
