Recent work has questioned the largely unconditional nature of charitable donations and explored the value of conditional giving with contemporary donors. In this paper, we extend this work by exploring how to operationalise features of conditionality in charitable giving, situated in the context of large international non-governmental organisations (NGOs). Building on prior engagements with international aid organisations, we present design considerations and a conceptual architecture supporting real-time, conditional giving for individual and institutional donations. Our architecture leverages properties of distributed-ledger technologies (DLT) to empower donors to (i) attach conditions to their donation, (ii) store funds in a secure, decentralised escrow and (iii) automatically release funds once conditions are met. Unlike prior work that envisions radical disintermediation and the removal of intermediate NGOs using DLT, our work recognises the expertise of NGOs in tackling complex global problems and instead investigates compelling new way for charities to increase transparency and accountability by introducing dynamic pledge controls. CCS Concepts: • Social and professional topics → Socio-technical systems; • Human-centered computing → Mobile computing; • Information systems → Collaborative and social computing systems and tools.

Beside reminiscing, the increasing cognitive decline in dementia can also be addressed through sensory stimulation allowing the immediate, nonverbal engagement with the world through one's senses. Much HCI work has prioritized cognitive stimulation for reminiscing or personhood often on small screens, while less research has explored sensory stimulation like the one enabled by large displays. We describe a year-long deployment in a residential care home of a wall-sized display, and explored its domestication through 24 contextual interviews. Findings indicate strong engagement and attachment to the display which has inspired four psychosocial interventions using online generic content. We discuss the value of these findings for personhood through residents' exercise of choices, the tension between generic/personal content and its public/private use, the importance of participatory research approach to domestication, and the infrastructure-based prototype, illustrated by the DementiaWall and its generative quality.

Smart Donations is a blockchain-based platform that enables users to program and set conditions on charitable donations. Users set up contracts to donate 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 over 8-weeks with 86 people and qualitatively analysed questionnaires and interviews about their experiences. Temporal qualities emerge when automation enforces conditions that determine when donations are made. These contributed to participants' sense of immediacy in donating to humanitarian crises, ongoing involvement while awaiting conditions to be met, and awareness of events that are usually unconscious. We suggest that automation can reveal diverse temporal registers, in real-world phenomena, sociality, morality and everyday life, which contribute to experiencing a 'right time' to donate. Thus, we recommend adopting a sensitivity to right time in designing for multiple temporalities in FinTech more generally.

University campuses are rapidly transitioning to environments that are rich in technology designed to support learning throughout the day and in diverse forms. Traditional lectures and seminars are supplemented with rich WiFi coverage, integrated learning environments, video lectures, public display networks and other innovations. Of these diverse technologies, the role and potential of public display networks in higher education is currently least understood. Indeed, most campus displays are merely used as means of information dissemination or as tools to support collaboration.In this paper, we explore the potential of pervasive display technologies as active contributors to university teaching and learning. We describe a real-world explorative study in which campus displays we used to stimulate student recall of lecture material. Our experiences demonstrate that public displays can be leveraged to provide prompts at opportune moments and invites further research in designing memory prompts to leverage the learning potential of pervasive displays in campus settings. The insights we garnered form a solid foundation and highlight opportunities and challenges in the field.

The increase in IoT sensing and actuating devices that are seamlessly integrated into the environment is often leading to a mistrust of users as it becomes impossible to spot deployed IoT devices and understand their purposes and capabilities. One approach is to provide an appropriate mechanism of mapping the IoT and address stakeholder requirements. However, providing comprehensive maps of the IoT may expose a number of vulnerabilities that need to be addressed. We conducted a comprehensive literature survey outlining the limitations of the existing body of work regarding the mapping of the IoT and conducting an appropriate threat analysis. We subsequently applied the STRIDE model to two case studies (smart campus and urban environment) to identify a set of potential vulnerabilities and approaches at addressing these issues in the context of IoT maps.
