Recent HCI research has focused on developing interactive technologies for cyclists and using technology to promote this activity. However, the community-building and advocacy aspects of cycling remain relatively unexplored. In this study, we explored the integration of urban cycling and participatory technology design to address transportation inequities and promote cycling advocacy in a US city characterized by infrastructural and social disparities. We engaged with nine bicycling advocates from five organizations in Baltimore, USA in participatory design activities to understand their motivations for promoting cycling in urban areas and how interactive technology can aid in creating a cyclist-friendly city. Along with the various practical motivations, we found the participants also promote cycling with a desire to challenge historical discriminatory practices and infrastructural inequalities and as a means of community building and identity expression. We identify three interconnected directions for future change: supporting ancillary bicycle infrastructure and DIY repair practices, changing perceptions through community engagement, and using technology to support community awareness and inclusion. We argue cycling can be a tool for resistance and identity shaping in this context, and participatory design can offer innovative directions for urban designers, policymakers, and system designers to strengthen efforts toward creating inclusive and equitable urban environments.

As online access to entertainment, education, news, and information increasingly becomes mitigated through subscription-based services, it is important to study how inequities in access impact users in low and middle-income countries (LMICS), and what infrastructuring strategies they employ to overcome obstacles. In this paper, we present findings from an interview study with 22 participants from Bangladesh who use and share online subscription-based services. Due to the lack of availability and limitations using formal international payment methods, procedural difficulties, and infrastructural challenges in Bangladesh, we found an emergence of a distinct informal ecosystem of accessing, sharing, and using subscription-based services. We report a detailed analysis of the adoption, sharing practices, and dynamics of sharing online subscription-based services in Bangladesh, that builds on and extends previous HCI literature on informality, informal marketplace, intermediaries, and media sharing in the Global South. Our findings show how a vibrant and growing user base of subscription-based online services is using creative and sometimes risky ways to gain access to media and information through informal intermediaries and administrators. Finally, we discuss potential directions for practice and policy innovations that include facilitating international payments for online services and platforms and reconsidering their policies and service delivery mechanisms to better support users in the Global South context.

As exploration of living media, biology, and biotechnology advances HCI, researchers call attention to implications for ethics. We respond with a qualitative study of audience engagement with multimedia bioart installation. Bioart comprises a transdisciplinary practice that brings diverse perspectives in art, science, and technology into dialogue and engages audiences. Understanding a bioart exemplar, Raaz, as disrupting habitual modes of being, we investigate audience experiences in three contexts, elaborating transdisciplinary community engagement that takes seriously living media and biotechnology and informs HCI broadly through vital authenticity, performative reflection, empowered critique, distributed expertise, and revealed dynamics. We discuss how transdisciplinary community engagement functions as a mode of inquiry and design that supports inclusive liminal experiences.

While the presence of religious content is rapidly increasing over digital media, the HCI literature on digital media production has remained mostly limited by its focus on secular contents and analyses. Hence, the production, politics, and impact of such religious videos from the Global South have remained understudied in HCI. In this paper, we shed light on this topic through our nine-month-long ethnographic study on the production, sharing, and consumption of Islamic sermon videos (locally known as Waz) in Bangladesh. We report how faith, informal learning, local collaboration, creativity, and care play crucial roles in creating Islamic sermon videos and their proliferation online. We discuss how the sermon videos create a religious counterpublic in Bangladesh. We further discuss how such faith-based media production makes important lessons pertinent to the national grassroots politics in the Global South, politics of social media platforms, and HCI4D scholarship.

While repair work has recently been getting increasing attention in HCI, recycling practices have still remained relatively understudied, especially in the context of the Global South. To this end, building on our eight-month-long ethnography, this paper reports the electronic waste (`e-waste', henceforth) recycling practices among the e-waste recycler (`bhangari') communities in Dhaka, Bangladesh. In doing so, this paper offers the work of the bhangaris through an articulation of their hands and their uses. Drawing from a rich body of scholarly work on social science, we define and contextualize three characteristics of the hand of a bhangari: knowledge, care, and skills and collaboration. Our study also highlights the pains and sufferings involved in this profession. By explaining bhangari work through the hand, we also discuss its implications for design, and its connection to HCI's broader interest in sustainability.
