PACMHCI, V9, N1, January 2025 Editorial

It is our great pleasure to introduce this issue of the Proceedings of the ACM on Human-Computer Interaction, which focuses on contributions from the research community on Supporting Group Work (GROUP). This thriving community is home to researchers within CSCW, HCI for practice-centered computing, sociotechnical studies, and interdisciplinary groups who provide theoretical, methodological, and/or conceptual contributions on collaborative technologies and practices. GROUP's research community vividly raises the awareness of dimensions of growing importance in our highly connected lives. The idea of caring through and with technology continues to be a rich and dynamic area for research, pointing to important challenges for elderly persons, parenting, and health. The increased availability of AI-based systems leads to the development of new practices that pose increasing issues for design and regulation. The domain of social media is especially concerned with fast-evolving practices and issues that raised major interest in our community. These aspects are also approached through design fiction as a way of futures-making. Workplace and hybrid work settings show also a central area where cooperation and teams are impacted. The research papers gathered in this issue account that we live in an unprecedentedly connected world, calling for more ethical reflections about the possibilities and caveats of digital technologies. The editorial board worked hard to organize this second submission round. The call for papers for this issue on GROUP attracted a total of 109 submissions from all over the world, of which 37 papers (34%) were accepted. This issue results from the dedicated volunteer effort of 36 members of the community who served as Associate Chairs (ACs) and 87 reviewers. They all lent their expertise and time to ensure high quality reviews and provide insightful feedback to all authors. The Editorial Board can be found on GROUP's track page. As Track Chairs, we are grateful for the community's collective efforts to continue shaping and sharing GROUP's contributions.
