“…Trajectory data have been widely used for spatial analysis problems, such as data mining for movement patterns (Taniar & Goh, 2007;Zheng, 2015), estimating urban movement (Iwata et al, 2017), traffic modelling (Xu et al, 2019;Zhao & Shi) and contact tracing (Kim et al, 2020;S et al, 2020;Vogt et al, 2021).…”

Identifying the places an infected person has visited during a virus incubation time in order to conduct contact tracing is currently done using manual interviews since proximity-based contact tracing methods do not store geolocation information due to privacy concerns. During the incubation time, an infected person might visit several locations and either forget where they went or are reluctant to disclose their trip details. To minimize manual location tracing while preserving the user's privacy, the authors propose a mesh block sequence method where the trajectories are transformed into a mesh block sequence before being shared with health authorities. These simulations show that this a useful method by which to protect user privacy by concealing specific details related to a trajectory. While this simulation uses an Australian administrative region structure, this method is applicable in countries which implement similar administrative hierarchical building blocks.

“…The government ran extensive radio, television, social media and poster campaigns (Australian Government Department of Health, 2020c) at an estimated cost of $AU7m (The Australian, 2021). The app itself cost approximately $AU4m to develop and $AU5.2m in operational costs, bringing the reported total cost of COVIDSafe to $AU16.2m (Vogt et al , 2022).…”

Purpose This paper aims to present a preliminary exploration of the intersections between the accounting and information systems (IS) disciplines. Using the illustrative example of the COVIDSafe app, released by the Australian federal government in response to the “wicked problem” of COVID-19, we demonstrate the value of interdisciplinarity to broaden the boundaries of accounting beyond a technical orientation to encompass social and moral considerations. Design/methodology/approach We apply a high-level view of socio-technical theory derived from the IS discipline by using a close-reading method of publicly available media and federal government sources related to the COVIDSafe app collected between April 2020 and April 2021. This theoretical lens allows for an enhanced understanding of the technical, environmental/regulatory, and social subsystems relating to accounting and accountability while supporting interdisciplinary reflection. Findings Addressing complex and wicked problems in accounting requires interdisciplinary approaches, whereby the accounting discipline must move beyond its technical origins. Dialogue between the accounting and IS disciplines is necessary to gain a deeper appreciation of the social, technical and moral implications of accounting in context. Research limitations/implications Viewing accounting beyond a technical practice through collaboration between accounting and IS offers a theorisation to consider the multi-dimensional nature of complex societal challenges. This theorisation can support the advancement of our practice and research meaningfully toward a view of accounting that centres on ideas of the public interest and the betterment of society. There remains much scope for progressing this dialogue, and we commend other scholars to engage in interdisciplinary work on the boundaries of accounting. Originality/value This study illustrates opportunities for accounting and IS approaches to solving “grand challenges”. Further, the study answers multiple calls for interdisciplinary discourse in accounting scholarship by contributing a socio-technical framing toward addressing complex challenges in our calculative era by initiating a dialogue that moves beyond accounting's traditional technical practice or the “accounting information systems” context.

Introduction The COVID-19 pandemic prompted public health teams across the world to emphasize case identification, contact tracing, and isolation in outbreak management strategies. Contact tracing was advanced by global access to mobile phones to develop and implement digital contact tracing (DCT) technology with the objective of increasing the rate of contact tracing while reducing the resources required. Purpose This study aimed to describe the DCT technology used during the COVID-19 pandemic across the world, and to identify differences and similarities between characteristics and uses. Methods This review followed the PRISMA (2020) guidelines for systematic reviews. Literature searches were conducted using Embase, MEDLINE, and PubMed and were restricted to English studies published between 2019 to 2023. Studies were excluded if they did not report findings for DCT during COVID-19, did not provide data for technology characteristics or outcomes, or were a study design listed for exclusion. Results Sixty one studies were included in the review producing results for 147 digital contact tracing technologies across 83 countries. The majority of digital contact tracing (DCT) technologies are government-owned (75.6%), primarily developed for COVID-19 tracing (96.4%). Bluetooth is the most favored technology (70%) used in their development, followed by GPS (30%) and QR codes (22%). Applications are the preferred platform (90.9%), with a few using applets (6.3%) and wearable devices (1.4%). Only 2 DCT technologies have achieved over 100 million downloads or uses (3.1%). Most DCTs fall into the 1–9.99 million downloads range (27.7%) and 10,000–99,999 downloads (20%). The majority of DCTs are voluntarily used by the population (63.6%), while 27.3% are mandated for use. Conclusions Digital contact tracing technologies were developed and implemented globally as a strategy in emergency outbreak management to reduce the spread of disease. This review describes the use of DCT across the world by identifying key features and characteristics that will serve as a lesson learned for improvement of existing DCT technologies for other emergency response outbreak management.
