"to be that one other brick in the pillar" : Online Communities, Platforms, and Collective Action in the BTS Industrial Complex
(Association for Computing Machinery, 2026-04-13) Ringland, Kathryn E.; Seetharaman, Bhavani; Her, Jhertau; Tan, Angeleen; Larsen, Bjarke Alexander; Mendoza, Lance; Carstensdottir, Elin; Oliver, Nuria; Shamma, David A.; Candello, Heloisa; Cesar, Pablo; Lopes, Pedro; Bozzon, Alessandro; Kosch, Thomas; Liao, Vera; Ma, Xiaojuan; Artizzu, Valentino; Draxler, Fiona; Lopez, Gustavo; Reinschluessel, Anke V.; Tong, Xin; Toups Dugas, Phoebe O.; Department of Computer Science
Social media platforms have become integral to everyday life and serve as the foundation for online communities. These platforms not only enable communication but also shape the ways in which online communities are formed and maintained. In this paper, we examine an online community, the BTS fandom ARMY, using Durkheim's concept of solidarity, we show how ARMY's symbolic commitments, collective labor, and boundary negotiations are simultaneously community practices and infrastructural labor that generate cultural and economic value. Using an online survey and ethnographic observations of BTS ARMY, we present the BTS Industrial Complex, an ecosystem of communities all related to BTS that rely on digital platforms to influence and interact with each other. Our contributions are threefold: (1) a conceptualization of the BTS Industrial Complex as a sociotechnical ecosystem, (2) empirical insights into how platforms shape collective action, and (3) implications for HCI in designing for and critically examining large-scale cultural economies.

Life Cycle Assessment of Icelandic Volcanic Pozzolans as Low-Carbon Supplementary Cementitious Materials
(Springer Science and Business Media Deutschland GmbH, 2026) Hamdallah, Mohammed; Costa, Diego; Heinonen, Jukka; Finger, David Christian; Bragança, Luís; Mateus, Ricardo; Tsikaloudaki, Katerina; Giarma, Christina; Kontoleon, Karolos; Askar, Rand; Salles, Adriana; Cervantes, Camila; Department of Engineering
The cement industry is a major contributor to global greenhouse gas emissions, predominantly due to clinker production. Supplementary Cementitious Materials (SCMs) represent an effective mitigation strategy, yet conventional SCMs such as Fly Ash (FA) and Ground Granulated Blast Furnace Slag (GGBFS) are becoming increasingly scarce. Volcanic pozzolans offer a promising natural alternative, and Iceland possesses extensive deposits that have not yet been evaluated from an environmental perspective. This study presents the first cradle-to-gate Life Cycle Assessment (LCA) of Icelandic Volcanic Pozzolan (VPI) production, drawing on primary data from three extraction sites and a planned processing facility in Þorlákshöfn—Lambafell, Litla Sandfell, and Landeyjahöfn—and secondary data from GaBi and Ecoinvent. A declared unit of one tonne of VPI is assessed across all ReCiPe 2016 midpoint impact categories. Results show that VPI’s climate change impact of 25.5 kg CO2-eq/t falls between FA (3–10 kg CO2-eq/t) and GGBFS (50–80 kg CO2-eq/t), confirming its competitiveness with established SCMs while offering the strategic advantage of abundant local supply. Marine dredging operations emerge as the dominant environmental hotspot, accounting for approximately 48.1% of total CO2-equivalent emissions. The findings confirm VPI as a robustly low-carbon SCM and support its large-scale adoption in sustainable cement production.
Clock Distribution with Gradient TRIX
(Association for Computing Machinery, 2025-06-13) Srinivas, Shreyas; Lenzen, Christoph; Department of Computer Science
Gradient clock synchronization (GCS) algorithms minimize the worst-case clock offset between the nodes in a distributed network of diameter D and size n. They achieve optimal offsets of ⊙(log D) locally, i.e., between adjacent nodes [14] and ⊙(D) globally [2]. A key open problem in this area is to achieve fault tolerance at minimal edge replication overhead.In this work, we achieve this goal under the assumption of an average-case distribution of faults, i.e., nodes fail with independent probability p ϵ o(n-1/2). In more detail, we present a self-stabilizing GCS algorithm for a grid-like directed graph with in- and out-degrees of 3. Note that even for tolerating a single fault, this degree is necessary, and if p was larger, it would not hold with probability 1 - o (1) that each node has at most one faulty in-neighbor. Our algorithm achieves asymptotically optimal local skew of ⊙(log D) with probability 1 - o(1); this holds under general worst-case assumptions on link delay and clock speed variations, provided they change slowly relative to the speed of the system.On the one hand, our results are of practical interest. As we discuss, the fault model is suitable for synchronously clocked hardware. Since our algorithm can simultaneously sustain a constant number of arbitrary changes due to faults in each clock cycle, it achieves sufficient robustness to dramatically increase the size of synchronously clocked systems.On the other hand, our results are of a theoretical interest. We show that for a worst-case distribution of f faulty nodes within our fault model's locality constraints, our algorithm achieves local skew O(5f log D). With probabilistically distributed faults, this becomes O(log D). Moreover, our work opens up avenues for further investigation of fault-tolerant synchronization, in particular trade-offs between fault distribution and edge density.
The Case of the Curious Robot : On the Social Viability of Curious Behavior in Non-Human Agents
(Association for Computing Machinery, Inc, 2024-12-26) Weatherwax, Kevin; Dooley, Doug; Carstensdottir, Elin; Takayama, Leila; Department of Computer Science
Curiosity is increasingly being looked at to develop interactive nonhuman agents capable of lifelong learning, particularly in the space of Ai driven agents. However, the way a non-human agent’s mental state is described could prime expectations in human counterparts as well as alter perceptions of an agent’s behavior. We conducted an online experiment examining people’s perceptions of four levels of curious behavior portrayed by a robot agent and whether this behavior matched people’s expectations when primed to anticipate a “curious” vs. “learning” vs. “autonomous” robot agent. As curiosity increased, the ratings of the robot agent’s thinking ability also increased. This was juxtaposed by a decrease in the robot’s ratings as an effective worker and social agent. Further, we captured a unique trajectory of expectation matching showing that agents’ internal mental states should be matched with analogous external behaviors. Our findings have implications for the design and development of non-human agents that engage in learning modeled on forms of human cognition.
