TL;DR: Including older adults as full stakeholders in digital society is a key priority for the next generation of policymakers and decision-makers.
Abstract: "The quest for youth—so futile. Age and wisdom have their graces too."— Jean Luc Picard
It is an increasingly global phenomenon that societies promote the notion of youth as the preferred state.a In stark contrast to the "wise elder" of ages past, today old age is assumed to be marked by loss of physical and cognitive ability, diminished relevance, and as we are sadly seeing with the COVID-19 pandemic, devalued humanity.18 In many ways, it is not surprising that such stereotypes are reflected in our technologies: tech companies compete for territory in an already overcrowded youth market; whereas older adults,b if considered users at all, are offered little more than fall alarms, activity monitors, and senior-friendly (often lower functionality) versions of existing tools. Meanwhile, there is a growing trend of workers aging out of the tech industry as early as their mid-40s,17 reflecting the higher value placed on the perspectives of those who represent the default target demographic.

TL;DR: Smart Donations as mentioned in this paper is a blockchain-based platform that offers users "contracts" that donate funds to certain causes in response to real-world events e.g., whenever an earthquake is detected or an activist tweets about refugees.
Abstract: Smart Donations is a blockchain-based platform that offers users ‘contracts’ that donate funds to certain causes in response to real-world events e.g., whenever an earthquake is detected or an activist tweets about refugees. We designed Smart donations with Oxfam Australia, trialled it for 8-weeks with 86 people, recorded platform analytics and qualitatively analysed questionnaires and interviews about user experiences. Temporal qualities emerge when automation enforces conditions that contributed to participants’ awareness of events that are usually unconscious, and senses of immediacy in contributing to crisis response and ongoing involvement in situations far-away while awaiting conditions to be met. We suggest data driven automation can reveal diverse temporal registers, in real-world phenomena, sociality, morality and everyday life, which contributes to experiencing a ‘right time’ to donate that is not limited to productivity or efficiency. Thus, we recommend a sensitivity to right time in designing for multiple temporalities in FinTech more generally.

TL;DR: The experiences of designing, developing and operating the world’s first comprehensive display personalisation service for mobile users are reported on, and a series of reflections are offered to inform the design of future systems.
Abstract: Widespread sensing devices enable a world in which physical spaces become personalised in the presence of mobile users. An important example of such personalisation is the use of pervasive displays to show content that matches the requirements of proximate viewers. Despite prior work on prototype systems that use mobile devices to personalise displays, no significant attempts to trial such systems have been carried out. In this article, we report on our experiences of designing, developing and operating the world’s first comprehensive display personalisation service for mobile users. Through a set of rigorous quantitative measures and 11 potential user/stakeholder interviews, we demonstrate the success of the platform in realising display personalisation, and offer a series of reflections to inform the design of future systems.

TL;DR: In this paper, the authors present a combination of a blockchain-native auditing and trust-enabling environment alongside a query exchange protocol, which allows the exchange of sets of patient identifiers between data providers in such a way that only identifiers lying in the intersection of set of identifiers are revealed and shared, allowing further secure and privacypreserving exchange of medical information to be carried out between the two parties.
Abstract: Data providers holding sensitive medical data often need to exchange data pertaining to patients for whom they hold particular data. This involves requesting information from other providers to augment the data they hold. However, revealing the superset of identifiers for which a provider requires information can, in itself, leak sensitive private data. Data linkage services exist to facilitate the exchange of anonymised identifiers between data providers. Reliance on third parties to provide these services still raises issues around the trust, privacy and security of such implementations. The rise and use of blockchain and distributed ledger technologies over the last decade has, alongside innovation and disruption in the financial sphere, also brought to the fore and refined the use of associated privacy-preserving cryptographic protocols and techniques. These techniques are now being adopted and used in fields removed from the original financial use cases. In this paper we present a combination of a blockchain-native auditing and trust-enabling environment alongside a query exchange protocol. This allows the exchange of sets of patient identifiers between data providers in such a way that only identifiers lying in the intersection of sets of identifiers are revealed and shared, allowing further secure and privacy-preserving exchange of medical information to be carried out between the two parties. We present the design and implementation of a system demonstrating the effectiveness of these exchange protocols giving a reference architecture for the implementation of such a system.
