Network analysis of the Danish bicycle infrastructure: Bikeability across urban-rural divides
No full textResearch on cycling conditions focuses on cities, because cycling is commonly considered an urban phenomenon. People outside of cities should, however, also have access to the benefits of active mobility. To bridge the gap between urban and rural cycling research, we analyze the bicycle network of Denmark, covering around 43,000 km and nearly 6 million inhabitants. We divide the network into four levels of traffic stress and quantify the spatial patterns of bikeability based on network density, fragmentation, and reach. We find that the country has a high share of low-stress infrastructure, but with a very uneven distribution. The widespread fragmentation of low-stress infrastructure results in low mobility for cyclists who do not tolerate high traffic stress. Finally, we partition the network into bikeability clusters and conclude that both high and low bikeability are strongly spatially clustered. Our research confirms that in Denmark, bikeability tends to be high in urban areas. The latent potential for cycling in rural areas is mostly unmet, although some rural areas benefit from previous infrastructure investments. To mitigate the lack of low-stress cycling infrastructure outside urban centers, we suggest prioritizing investments in urban–rural cycling connections and encourage further research in improving rural cycling conditions
Guidelines for Empirical Studies in Software Engineering involving Large Language Models.
No full textLarge language models (LLMs) are increasingly being integrated into software engineering (SE) research and practice, yet their non-determinism, opaque training data, and evolving architectures complicate the reproduction and replication of empirical studies. We present a community effort to scope this space, introducing a taxonomy of LLM-based study types together with eight guidelines for designing and reporting empirical studies involving LLMs. The guidelines present essential (must) criteria as well as desired (should) criteria and target transparency throughout the research process. Our recommendations, contextualized by our study types, are: (1) to declare LLM usage and role; (2) to report model versions, configurations, and fine-tuning; (3) to document tool architectures; (4) to disclose prompts and interaction logs; (5) to use human validation; (6) to employ an open LLM as a baseline; (7) to use suitable baselines, benchmarks, and metrics; and (8) to openly articulate limitations and mitigations. Our goal is to enable reproducibility and replicability despite LLM-specific barriers to open science. We maintain the study types and guidelines online as a living resource for the community to use and shape (see: https://llm-guidelines.org/
Exploring the Entanglement of Relational Design, Spatiality and Places
No full textOver the last two decades, we have witnessed a relational turn in design research, embracing the entanglements of human and non-human elements in socio-material arrangements. Despite the foregrounding of relations in these entanglements, little attention has been given to what role spatiality and places may have in relational design. This workshop explores the entanglement of relational design, spatiality and places based on design case studies from participants. Using a design charette methodology, participants will collaboratively (1) map how relational entanglements shape and are shaped by design research and practice; (2) identify and unpack cross-disciplinary tensions and opportunities; and (3) co-create a vision and action plan for bridging silos and fostering collaboration across disciplines. The aim is to build an interdisciplinary understanding of the intimate entanglement of human and non-human elements, spatiality and places in the complex social-material arrangements we engage with in relational design
From bones to bytes: anticipating and addressing the governance challenges of human digital remains and posthumous digital human twins
No full textDuring the nineteenth century, advances in medical research led to grave robbing and an illicit market in human biological remains (HBR). The historical episode of grave robbing illustrates how science can upend social norms. A similar scenario could soon emerge, but this time it will not be with people's biological remains, but with people's digital remains. Artificial intelligence and extended reality now create digital representations from avatars to human digital twins. In addition to the sophisticated digital appearance, the representations are drawing on personal and biometric data to create complex behavioural and biological replications of people. These digital artefacts form part of a person's digital estate, which persists after death as Human Digital Remains (HDR). HDR presents an urgent socio-technological risk because like the 19th-century trade in HBR, HDR presents existing legal and ethical gaps. . The research responds by adopting what is to our knowledge, the first of its kind cross-disciplinary study that combines conceptual analysis, anticipatory and precautionary governance frameworks, and doctrinal review to analyse and anticipate legal and ethical gaps and grey areas. Our analysis shows that neither General Data Protection Regulation (GDPR) nor the AI Act (2025) currently extends rights to the deceased. In response, we outline a HDR governance framework, supported by six targeted policy-facingrecommendations: (1) build HDRspecific anticipatory governance capacity, (2) innovate and safeguard posthumous privacy and data protections, (3) protect citizen autonomy with advance data directives and data trustees, (4) leverage existing tools by developing a data-donor card and support the right to gift or trade HDR, (5) enhance the right to be forgotten post-mortem, and (6) update digital identity and legacy rights, including the right to continuation or erasure of Digital Human Twins
Danish Game Industry Timeline
No full textThis timeline collects landmarks and events to present an overview of Danish digital game development. It showcases the formation of Danish game development from early grassroot networks and state inquiries to, among other things, the Law of NIMBI GameLab - Denmark's Institute for Game Development coming into effect in 2025
Reminiscences on Influential Papers
No full textThis issue's contributors cover the impact of paying attention to the low-level implementation details, a paradigm shift in the way we approach stream processing, and the value of combining theoretical analysis with experimental evaluation. Furthermore, one of our contributors, rather than picking one paper, highlights the importance of putting the time to practice reading, reviewing, and learning from papers, not only from one's own field of interest but also from other fields. VLDB, similar to some systems conferences, launched a Shadow Program Committee for this purpose following the VLDB 2026 (Vol 19) submission cycles. We wish to continue this effort in the future VLDB cycles. Enjoy reading!While I will keep inviting members of the data management community, and neighboring communities, to contribute to this column, I also welcome unsolicited contributions.

Towards a Framework for Exploring Synthetic Voices in VUI Design
No full textThe last decade has seen voice assistants like Apple's Siri and Google's Home become truly ubiquitous. These devices – and many more – rely on Voice-based User Interfaces (VUIs) that specify what the devices can listen for and how they express themselves through synthetic voice design. Today, primarily Western VUI designs often reproduce anthropomorphic and heteronormative vocal stereotypes and interaction scenarios. Instead, we propose an emergent framework for VUI design that opens for a multifaceted exploration of how VUIs sound, what this means for their sociocultural role and how it shapes interactions. The framework extends current VUI design concerns with concepts from sound studies that offer a richer foundation for exploring VUIs’ sonic expressions. We present the theoretical foundations of the framework and how it has developed over three collaborative workshops bringing together sound artists, sound researchers and interaction designers. We outline the framework in detail and point to future experiments and perspectives for expanding the VUI design space
Autonomous Regulation of Social Media Use: Implications for Self-control, Well-Being, and UX
No full textMuch work in HCI has investigated strategies for supporting au-tonomous self-regulation in social media use (SMU): helping usersto control their time online and ensure it serves personally valuedoutcomes. However, results suggest that the effectiveness and ac-ceptability of these strategies may vary based on individual needs.Recent work has attributed this variation to motivational factors,though we currently lack data to understand how these factorsinfluence self-regulation, user experience and well-being. We drawon Self-Determination Theory to analyse autonomous and non-autonomous patterns of motivation in 521 users of social media.Using latent profile analysis, we identify 4 “motivational profiles”associated with significant differences in need satisfaction, affect,and compulsive engagement. Our results clarify distinct aspectsof autonomy in SMU and identify opportunities to target and per-sonalise design interventions; they suggest autonomous regulationcan be associated with better experience and well-being, thoughnot necessarily less time online

Introduction: Carbon and Culture Change
No full textThis introduction and the volume as a whole discuss the transformational role that carbon has come to play in social and cultural life. As a proxy for greenhouse gas emissions, carbon has become a phenomenon that can no longer be accounted for solely within the technoscientific vocabulary of climate scientists or as an economic externality to human modes of production. As a new value form, carbon has entered individual and collective imaginaries across the globe. We contend that this entrance is by no means uniform. The introduction thus attends to carbon as a range of diverse phenomena in human lives and, second, to the way that it can be approached as culture. It continues with a discussion of carbon's potential for generating or promoting change, before turning to the different contributions to this volume, and how they provide unique perspectives on the topic of carbon as a cultural phenomenon. The chapters are thus framed through a focus on the diverse meanings ascribed to carbon in different cultural contexts. In sum, in the introduction, together with the volume as a whole, we demonstrate how paying attention to carbon as a cultural phenomenon allows for a more profound appreciation of when, how and why carbon enables (or sometimes disables) change in the form of green transitions or transformations
