論文アブストラクト： Road congestion, air pollution and sustainability are increasingly important in major cities. We look to understand how last-mile deliveries in the parcel sector are impacting our roads. Using formative field work and quantitative analysis of consignment manifests and location data, we identify how the effectiveness of life-style couriers is contributing to both environmental and non-environmental externalities. This paper presents an analysis of delivery performances and practices in last-mile logistics in central London, quantifying the impacts differing levels of experience have on overall round efficiency. We identify eleven key opportunities for technological support for last-mile parcel deliveries that could contribute to both driver effectiveness and sustainability. We finish by examining how HCI can lead to improved environmental and social justice by re-considering and realizing future collaborative visions in last-mile logistics.
論文アブストラクト： The Urban Heat Island Effect (UHI) is a phenomenon whereby cities tend to be hotter than suburbs. We frame the UHI as a "wicked problem" that poses a range of economic, healthcare, and social challenges. Our paper examines how different stakeholders negotiate complex value systems, collect data, and rely on collaborative platforms to address the problem of urban heat. Using documentary filmmaking as a research method, we conducted ethnographically-oriented interviews with participants including vulnerable communities, urban architects, microclimate researchers, and grassroots activists. Our findings reveal that unlike problems that can be solved using traditional HCI paradigms of distributed work, the UHI presents an entanglement of challenges that do not necessarily converge on a single solution. We conclude by discussing two opportunities for addressing wicked problems through social computing: knowledge systems for sharing hybrid data across domains and interactive forums for discourse among diverse actors.
