This paper examines the collaborative work of residents, housing associations, and property owners to manage household waste in the context of a multi-apartment housing complex. Framed within the feminist ecological perspective of digital environmental stewardship - that is, how diverse actors, motivations, and capacities producing care for the environment that can be digitally mediated - we unpack how the many involved actors work together to keep waste in place, maintain the local waste system, and call on 'responsibility' as a means to produce sustainable actions and accountability. We frame these practices of waste management within the mundane work of sociotechnical innovation. Borrowing from Jackson's notion of repair work, we weave together an argument for the novel and valuable contribution to CSCW sustainability research grounded in the everyday contingent emergencies of environmental care. We argue for approaches to sustainability that reflect both the work to maintain sustainability -not just to produce it- and aspects of the 'good enough', a locally and reflexively produced equilibrium between maintenance and repair. We conclude by discussing their relevance for the design of sociotechnical interventions that mediate practices of care in waste management.

This one-day workshop sets out to discuss academic impact, its multi-faceted meanings and, therefore, the various ways it can be achieved. Over the last year, for both HCI research and other academic fields, impact has become a key notion to assess research, including the evaluation of funding proposals, project outcomes, and departments. Expressions, such as, community outreach, environmental harms and benefits, societal relevance, or industry interests are all expressions that can be associated with this growing focus. Yet, questions remain about the audience of academic research, the societal role of academia, the tensions between corporate-driven technological trends and critical intellectual interests, and how mutually beneficial partnerships between academia and other actors can be developed. The theme of this year’s conference “Computing [in] Crisis” reminds us of the importance of such questions and the urge for future research to take them seriously. The workshop will provide a platform for HCI researchers, practitioners, representatives of public institutions, and diverse interested actors to discuss impact, and how a future research agendas that take it seriously might look like. We plan to accept up to twenty contributions and run the workshop on-site.

Automated Grading Systems (AGSs) are increasingly used in higher education assessment practices, raising issues about the responsibilities of the various stakeholders involved both in their design and use. This study explores how teachers, students, exam administrators, and developers of AGSs perceive and enact responsibilities around such systems. Drawing on a focus group and interview data, we applied Fuchsberger and Frauenberger’s [27] notion of Doing Responsibilities as an analytical lens. This notion, framing responsibility as shared among human and nonhuman actors (e.g., technologies and data), has guided our analysis of how responsibilities are continuously configured and enacted in university assessment practices. The findings illustrate the stakeholders’ perceived and enacted responsibilities at different phases, contributing to the HCI literature on Responsible AI and AGSs by presenting a practical application of the ‘Doing Responsibilities’ framework before, during and after design. We discuss how the findings enrich this notion, emphasising the importance of engaging with nonhumans, considering regulatory aspects of responsibility, and addressing relational tensions within automation.

This paper explores the potential of (re)framing the smart fridge to facilitate asynchronous food-sharing practices within activist communities. Empirical data were gathered through a co-design study with FoodSharing Stockholm community members between March 2022 and December 2023. This investigation delved into the opportunities and challenges of incorporating a smart fridge into their activist efforts towards local food waste reduction. Our findings highlight managing fairness, cleaning and maintenance, and community building as crucial considerations in designing for such activist, community settings. We introduce design concepts for four adaptable and configurable smart devices to modify existing community fridges and address the above considerations. This paper contributes to HCI by illustrating the intricate relations between ‘making an impact’, ‘building community’, and the design of ‘engagement through technology’ within food-sharing communities. It underscores the significance of designing smart fridges for activist food-sharing communities with a purpose that goes beyond mere functionality, emphasising the need to consider the broader social implications of digital interventions in facilitating local food waste reduction and community building.

This one-day workshop invites discussions on the role of data and data-enabled practices in addressing challenges of environmental sustainability. Fostering acts of care for the environment is a complex endeavor entailing multi-lifespan relations to people and institutions, to the environment and other non-human actors, and to existing infrastructures and processes. The workshop addresses such challenges by exploring the role of data, and the work of making them actionable for the many actors involved in protecting the environment. It will bring together interdisciplinary scholars, representatives of public institutions, activists, environmental collectives, and IT practitioners interested in the design of more sustainable futures. The workshop will discuss analytical and design issues of data-enabled sustainability, along with the practical opportunities of using data to infrastructure acts of care for the environment. The workshop will accommodate up to twenty participants and will be mainly run on-site.

Waste management in urban areas is a complex process, encompassing a variety of activities (e.g., acquiring, sorting, disposing),actors (e.g., single individuals, waste collectors, condominium associations), and capacities (e.g., from household recycling stations to physical infrastructures such as recycling and sorting facilities).Whereas previous HCI design research has tackled problems with waste management from an individual, behavioral change perspective, we approach this design space through a feminist ecological design perspective of Digital Environmental Stewardship. Through a combination of qualitative empirical data and materials generated at design workshops, we outline challenges related to waste management in a complex of five multi-apartment buildings. We propose a number of design explorations addressing such challenges, and reflect on the generative role of the DES framework in framing design from a collective and ecological perspective.

This paper extends the literature on social media activism by foregrounding the invisible work of orchestrating online activism. We analyze the activities of a #MeToo group in a Northern European country and characterize the group's efforts to catalog incidents of gender-based harassment and discrimination as an activist, platform-mediated participatory writing project. Our analysis details the work of organizing this form of activism, particularly: 1) the editorial work that underlies publishing personal stories on social media, 2) the emotional labor that happens as part of this form of writing, and 3) the work of creating publics. By drawing attention to these efforts, the paper frames activism as effortfully driven, sometimes in tension with the platform or evolving value positions. We conclude with a discussion on the role of social networking sites in organizing activism where writing is central, and with a set of sensitivities that can support designers and activists alike in designing socio-technical practices concerned with social change.

The scope of Sustainable HCI research is expanding to include the broad sociotechnical and ecological contexts of computing. We examine the intersection of environmental sustainability, technology, and the law. By studying the legal dispute between a platform service that facilitates crowd-sourced waste disposal and the local government’s regulation of waste management, we step through an evolving debate on the meaning of care and responsibility for the environment. When faced with the municipality’s claimed monopoly on responsibility for waste management, the platform argues for the paradigms of individual responsibility, designing for user needs, and personalised and on-demand digital services. In arguing against this framing, the municipality highlights the gap between the law, its interpretation, and the idealistic values of technology-driven environmental care. We contribute to the framing of environmental care within Sustainable HCI as a locally constructed, regulated, and contested aspect of technology design and appropriation.
