Current online safety technologies overly rely on parental mediation and often fail to address the unique challenges faced by youth in the Child Welfare System (CWS). These youth depend on a complex ecosystem of support, including families, caseworkers, and advocates, to safeguard their wellbeing. Within this network, Guardians ad Litem (GALs) play a unique role as court-appointed advocates tasked with ensuring the best interests of youth. Yet little is known about how GALs perceive and support youths' online safety. To address this gap, we conducted a two-part workshop with 10 GALs to explore their perspectives on online safety and collaboratively envision technology-based solutions tailored to the needs of youth in the CWS. Our findings revealed that GALs struggle to support youth with online safety challenges due to limited digital literacy, inconsistency of institutional support, lack of collaboration among stakeholders, and complexity of family dynamics. While GALs recognized the need for some oversight of youth online activities, they emphasized designing systems that support online safety beyond control or restriction by fostering stability, trust, and meaningful interactions, both online and offline. GALs emphasized the importance of developing tools that enable ongoing communication, therapeutic support, and coordination across stakeholders. Proposed design concepts focused on strengthening youth agency and cross-stakeholder collaboration through virtual avatars and mobile apps. This work provides actionable design concepts for strengthening relationships and communication across care network. It also redefines traditional approaches to online safety, advocating for a holistic, multi-stakeholder online safety paradigm for youth in the CWS.

Team closeness provides the foundations of trust and communication, contributing to teams' success and viability. However, newcomers often struggle to be included in a team since incumbents tend to interact more with other existing members. Previous research suggests that online communication technologies can help team inclusion by mitigating members' perceived differences. In this study, we test how virtual reality (VR) can promote team closeness when forming teams. We conducted a between-subject experiment with teams working in-person and VR, where two members interacted first, and then a third member was added later to conduct a hidden-profile task. Participants evaluated how close they felt with their teammates after the task was completed. Our results show that VR newcomers felt closer to the incumbents than in-person newcomers. However, incumbents' closeness to newcomers did not vary across conditions. We discuss the implications of these findings and offer suggestions for how VR can promote inclusion.

Although domestic work is often viewed as manual labor, it involves significant interaction with online technologies. However, the detailed exploration of how domestic workers use these technologies remains limited. This study examines the impact of online technologies on domestic workers' work practices, perceptions, and relationships with customers and employers. We interviewed 30 domestic workers residing in the United States, who provided examples that highlight the insufficient transformative role of current online technologies in their work. By conducting a thematic analysis, we characterize how they approach and avoid these digital tools at different stages of their work. Through these findings, we investigate the limitations of technology and identify challenges and opportunities that could inform the design of more suitable tools to improve the conditions of this marginalized group.

Beyond the well-known giants like Uber Eats and DoorDash, there are hundreds of independent food delivery platforms in the United States. However, little is known about the sociotechnical landscape of these "indie'' platforms. In this paper, we analyzed these platforms to understand why they were created, how they operate, and what technologies they use. We collected data on 495 indie platforms and detailed survey responses from 29 platforms. We found that personalized, timely service is a central value of indie platforms, as is a sense of responsibility to the local community they serve. Indie platforms are motivated to provide fair rates for restaurants and couriers. These alternative business practices differentiate them from mainstream platforms. Though indie platforms have plans to expand, a lack of customizability in off-the-shelf software prevents independent platforms from personalizing services for their local communities. We show that these platforms are a widespread and longstanding fixture of the food delivery market. We illustrate the diversity of motivations and values to explain why a one-size-fits-all support is insufficient, and we discuss the siloing of technology that inhibits platforms' growth. Through these insights, we aim to promote future HCI research into the potential development of public-interest technologies for local food delivery.
