Socioeconomic disparities in heat exposure in India
Heat exposure is an escalating public health concern, where limited policy attention and infrastructure constraints hinder effective risk assessment and response. This study introduce a multi-perspective and multi-scale analytical framework to quantify socioeconomic disparities in heat exposure using spatiotemporally resolved data, providing key insights for targeted public health interventions and policy development. Taking India as the study ar…
How to do things with a keyword
While people regularly employ the term values in mundane interactions and political debates on social media, little is known about its function in public communication. Approaching values as a keyword in everyday communication, we asked: In what contexts do Twitter users invoke the term values? What discursive functions does the term serve? How do these contexts and functions differ across languages? To address these questions, we analyzed approx…
How do people evaluate the accuracy of video posts when a warning indicates they were generated by AI
Given the rise of concerns about Generative Artificial Intelligence (GenAI) powered misinformation, major platforms like Google, Meta, and TikTok have implemented new policies to warn users of AI-generated content. However, we have not fully understood the impacts of such user interface designs that disclose AI made content on user perceptions. This study investigates how people assess the accuracy of video content when they are warned that it is…
Power and Relatedness in the Construction of Images and Emotions Toward Foreign Countries
In this study, we systematically explore the relationships between the emotions that people have toward foreign countries and their attributes. We conducted surveys in two different countries–Japan and Israel, yet our findings reveal similar patterns. In both Japan and Israel, we found that the perceived power and relationship with foreign countries as well as their attributes can evoke certain types of emotions. The economic and political perfor…
Enhancing geospatial retail analysis by integrating synthetic human mobility simulations
The accuracy of retail location models depends on their precise calibration, but the data necessary for such a key task is seldom available. In this research, we use synthetic human mobility data, which introduces commuting dynamics, to improve the reliability of such models. We use the origin-destination flows to distribute households' potential expenditures in their home and commuting locations with the aim of modeling non-residential-driven de…

A cost-and-effect simulation model for compact city approaches
Japan's compact-city policy addresses rapid population decline and aging to ensure sustainable development. However, its implementation requires significant time, financial resources, and complex stakeholder collaborations. Faced with these challenges, we asked: How can the cost-and-effect of planning be simply and automatically recognized by stakeholders? To address this, a simulation model was developed for evaluating urban planning strategies …
Emotions, behaviors and places
Emotions are the basis of human behavior and an important part of spatial constructions. Despite numerous efforts to leverage spatio-temporal big data from social media to capture public sentiments, there is a lack of understanding of how individuals' behaviors play a role in people's sentiments at places they visit. Thus, this study aims to advance our understanding of the complex relationships between sentiments, behaviors, and places. Through …
Social segregation levels vary depending on activity space types
Given the dynamic spatial characteristics of modern cities, the issue of social segregation based on activity spaces has been gaining increased attention. However, few studies have performed a detailed comparison of the differences in social segregation at different types of activities space on the citywide scale with a relatively small granularity from both place and individual perspectives. To gain a better understanding of the intricate and dy…
How to Do Things With “Values”
The term _values_ is prominent in political discourse. Yet its ubiquity is matched by its vagueness, especially when considering usage among different cultures. Twitter provides a promising venue for exploring the contested political discourse surrounding this term. In this paper, we study the use of the term values on Twitter across different language communities. We ask: _what meanings do users ascribe to the term “values”?_ and _what are the s…
Mapping HCI research methods for studying social media interaction
In the last decades, researchers in Human-computer interaction (HCI) took numerous efforts to investigate people's social media interaction. To understand how researchers in HCI have studied social media interaction, we examined 149 peer-reviewed articles published between 2008 and 2020 in major HCI conference proceedings and journals. We systematically reviewed the methodologies HCI researchers applied, the research topics these methods covered,…
