Who Uses Whose Telescopes? Analyzing the Knowledge Geography and Research Dominance of Global Astronomical Facilities
Large-scale research infrastructures (LSRIs) are central to contemporary science policy, combining massive capital investments with international access regimes. Yet whether open access to these infrastructures translates into more equitable scientific authority remains contested. Astronomy provides a critical case: world-leading observatories are globally shared but embedded in specific national contexts. We compile a novel country--year dataset (1955--2025) linking the location of astronomica…

International promotion patterns in the smart city literature: Exploring the role of geography in affecting local drivers and smart cities' outcomes
The rise of smart cities represents a significant trend in urban development. However, only in recent years has attention shifted toward the international promotion of these cities. Despite ongoing academic discussions on the impact of smart city development on urban environments, the global recognition of smart cities remains uncertain due to their multidisciplinary nature. To address this, we conducted a systematic literature review of articles published in top-tier peer-reviewed journals fro…

Good Morning #Canada
Normally, I'm posting about history or geography or trivia, but the July tourism numbers are dominating the news. We "Nasty" Canadians are choosing not to visit the USA, and trips across the border continue to drop month after month. At the end of 2024, U.S. tourism revenue from Canadians was projected to increase 16%. Surprise! Losses by USA businesses are already estimated to be in excess of $20B USD, and some states are bracing for government cuts due to a decrease in sales taxes.

Economy and Geography Shape the Collective Attention of Cities
Complex networks are commonly used to explore human behavior. However, previous studies largely overlooked the geographical and economic factors embedded in collective attention. To address this, we construct attention networks from time-series data for the United States and China, each a key economic power in the West and the East, respectively. We reveal a strong macroscale correlation between urban attention and Gross Domestic Product (GDP). At the mesoscale, community detection of attention…

Is this feasible everywhere?
Maybe not, depending on population density and geography.
However, it's not a big mystery where floods will happen and we figured this out long ago—there's no reason anyone should live there and we know in advance when they happen to evacuate anyone being temporarily around.

Man, I'm a sucker for history but this was *fascinating*.
It's shocking how far things fall in America from their apogee. This is close to Gary, Indiana which at one point was the world's biggest manufacturing hub, and now has literal trees growing out of the gorgeous old buildings.
Next time I'm passing that way I'm gonna see if I can find this.

Global Patterns of Knowledge: Language, Genre, and the Geography of Knowledge
Online platforms, particularly Wikipedia, have become critical infrastructures for providing diverse linguistic and cultural contexts. This human-curated knowledge now forms the foundation for modern AI. However, we have not yet fully explored how knowledge production capability vary across languages and domains. Here, we address this gap by applying economic complexity analysis to understand the editing history of Wikipedia platforms. This approach allows us to infer the latent mode of ``knowl…

"Airdrops would usually be ordered as a last resort to feed people in emergency situations where hostile armed forces or geography make road deliveries impossible. In Gaza the only obstacles to driving aid across the border are restrictions imposed by Israel, an ally of many western nations including Britain, and armed with British and US weapons"

I have a question: Let's say, I have a (rather long) list of coordinates in a not very widely used coordinate reference system (World Mollweide, EPSG:54009 in this case). Is there an easy way to convert that into something more widely used?
Something like csv in > csv out, only with different coordinates?

The U.S.-Mexico border is no longer just a line on a map;
it is a roaming force, drifting through our cities and ravaging schools, courthouses and workplaces.
It has become unmoored from geography, dragging its violence and impunity into the heart of American life.
Once confined to the borderlands, the Border Patrol — with its culture of Wild West impunity — is now operating across the country,
joining Immigration and Customs Enforcement in raids far from ports of ent…

Global Supply Chain Reallocation and Shift under Triple Crises: A U.S.-China Perspective
US-China trade tensions, the COVID-19 pandemic, and the Russia-Ukraine conflict have disrupted and reshaped global supply chains. Existing studies caution that these tensions may not meaningfully reduce U.S. dependence on China-linked supply chains. This study examines the drivers of this unmet reallocation under overlapping geopolitical and public health disruptions. It investigates how these shocks jointly reconfigured bilateral trade and global value chain (GVC) participation and positioning…

Community-Centered Spatial Intelligence for Climate Adaptation at Nova Scotia's Eastern Shore
This paper presents an overview of a human-centered initiative aimed at strengthening climate resilience along Nova Scotia's Eastern Shore. This region, a collection of rural villages with deep ties to the sea, faces existential threats from climate change that endanger its way of life. Our project moves beyond a purely technical response, weaving together expertise from Computer Science, Industrial Engineering, and Coastal Geography to co-create tools with the community. By integrating generat…

2-cabling and tangle operators in Khovanov theory

2-cabling and tangle operators in Khovanov theory
We describe an operator on 4-ended tangles that is induced by 2-cabling of a strongly invertible knot. By passing to the 4-ended tangle Khovanov theory of Kotelskiy-Watson-Zibrowius, this induces an operator on the category of type D structures over the Bar-Natan algebra $\mathcal{B}$, as well as on a Fukaya category of the 4-punctured 2-sphere. We provide a full description of this operator's restriction to cap-trivial tangles. Finally, we extract geography results that are inspired by a recen…

Feature-free regression kriging
Spatial interpolation is a crucial task in geography. As perhaps the most widely used interpolation methods, geostatistical models -- such as Ordinary Kriging (OK) -- assume spatial stationarity, which makes it difficult to capture the nonstationary characteristics of geographic variables. A common solution is trend surface modeling (e.g., Regression Kriging, RK), which relies on external explanatory variables to model the trend and then applies geostatistical interpolation to the residuals. Ho…

Causal Decomposition Analysis with Synergistic Interventions: A Triply-Robust Machine Learning Approach to Addressing Multiple Dimensions of Social Disparities
Educational disparities are rooted in and perpetuate social inequalities across multiple dimensions such as race, socioeconomic status, and geography. To reduce disparities, most intervention strategies focus on a single domain and frequently evaluate their effectiveness by using causal decomposition analysis. However, a growing body of research suggests that single-domain interventions may be insufficient for individuals marginalized on multiple fronts. While interventions across multiple doma…

Gerrymandering and geographic polarization have reduced electoral competition
Changes in political geography and electoral district boundaries shape representation in the United States Congress. To disentangle the effects of geography and gerrymandering, we generate a large ensemble of alternative redistricting plans that follow each state's legal criteria. Comparing enacted plans to these simulations reveals partisan bias, while changes in the simulated plans over time identify shifts in political geography. Our analysis shows that geographic polarization has intensifie…

AI-Driven Spatial Distribution Dynamics: A Comprehensive Theoretical and Empirical Framework for Analyzing Productivity Agglomeration Effects in Japan's Aging Society
This paper develops the first comprehensive theoretical and empirical framework for analyzing AI-driven spatial distribution dynamics in metropolitan areas undergoing demographic transition. We extend New Economic Geography by formalizing five novel AI-specific mechanisms: algorithmic learning spillovers, digital infrastructure returns, virtual agglomeration effects, AI-human complementarity, and network externalities. Using Tokyo as our empirical laboratory, we implement rigorous causal identi…
