The hierarchical organization of urban social overlap: How shared social spaces diverge from physical mobility
Bibandhan Poudyal, Mariana Macedo, Ronaldo Menezes +1
Cities are commonly characterized through population density, infrastructure, and mobility flows. These quantities describe where people are and how they move, but movement does no…
A Shared IPTC Topic Space for Cross-Source Topic Modelling
Din Iskakov, Sebastian Gonçalves, Marco Idiat +4
Comparing topic attention across different media is hindered by a fundamental modelling problem: topic models fitted separately to each corpus produce corpus-specific topic spaces…
Vector fields as a framework for modelling the mobility of commodities
Sima Farokhnejad, Angélica S. da Mata, Mariana Macedo +1
Commodities, including livestock, flow through trade networks globally, with trajectories that can be effectively captured using mobility pattern modelling approaches similar to th…
Super-Linear Growth and Rising Inequality in Online Social Communities: Insights from Reddit
Guilherme Machado, Diogo Pacheco, Ronaldo Menezes +1
We study the effect of the number of users on the activity of communities within the online content sharing and discussion platform Reddit, called subreddits. We found that comment…
Validating Urban Scaling Laws through Mobile Phone Data: A Continental-Scale Analysis of Brazil's Largest Cities
Ricardo de S Alencar, Fabiano L. Ribeiro, Horacio Samaniego +2
\abstract{Urban scaling theories posit that larger cities exhibit disproportionately higher levels of socioeconomic activity and human interactions. Yet, evidence from developing c…
Systematic comparison of gender inequality in scientific rankings across disciplines
Ana Maria Jaramillo, Mariana Macedo, Marcos Oliveira +3
Participation of Women in academia has grown over recent decades. Yet, it is unclear how this growth translates into representation at the top of academic rankings (measured by sci…
The parenthood effect in urban mobility
Mariana Macedo, Ronaldo Menezes, Alessio Cardillo
We investigate how parenthood and marriage (two major life events) reshape urban mobility patterns, an aspect overlooked in traditional `average citizen' mobility models. Leveragin…
Understanding the Structure and Resilience of the Brazilian Federal Road Network Through Network Science
Julio Taveira, Fernando Buarque de Lima Neto, Ronaldo Menezes
Understanding how transportation networks work is important for improving connectivity, efficiency, and safety. In Brazil, where road transport is a significant portion of freight…
Geographical Isolation as a Driver of Political Violence in African Cities
Rafael Prieto-Curiel, Ronaldo Menezes
Violence is commonly linked with large urban areas, and as a social phenomenon, it is presumed to scale super-linearly with population size. This study explores the hypothesis that…
Environmental Insights: Democratizing Access to Ambient Air Pollution Data and Predictive Analytics with an Open-Source Python Package
Liam J Berrisford, Ronaldo Menezes
Ambient air pollution is a pervasive issue with wide-ranging effects on human health, ecosystem vitality, and economic structures. Utilizing data on ambient air pollution concentra…
A Data-Driven Supervised Machine Learning Approach to Estimating Global Ambient Air Pollution Concentrations With Associated Prediction Intervals
Liam J Berrisford, Hugo Barbosa, Ronaldo Menezes
Global ambient air pollution, a transboundary challenge, is typically addressed through interventions relying on data from spatially sparse and heterogeneously placed monitoring st…
A Framework for Scalable Ambient Air Pollution Concentration Estimation
Liam J Berrisford, Lucy S Neal, Helen J Buttery +2
Ambient air pollution remains a critical issue in the United Kingdom, where data on air pollution concentrations form the foundation for interventions aimed at improving air qualit…
Does Transport Inequality Perpetuate Housing Insecurity?
Nandini Iyer, Ronaldo Menezes, Hugo Barbosa
With trends of urbanisation on the rise, providing adequate housing to individuals remains a complex issue to be addressed. Often, the slow output of relevant housing policies, cou…
Network Entropy as a Measure of Socioeconomic Segregation in Residential and Employment Landscapes
Nandini Iyer, Ronaldo Menezes, Hugo Barbosa
Cities create potential for individuals from different backgrounds to interact with one another. It is often the case, however, that urban infrastructure obfuscates this potential,…
Mobility and Transit Segregation in Urban Spaces
Nandini Iyer, Ronaldo Menezes, Hugo Barbosa
Segregation is a highly nuanced concept that researchers have worked to define and measure over the past several decades. Conventional approaches tend to estimate segregation based…
The structure of segregation in co-authorship networks and its impact on scientific production
Ana Maria Jaramillo, Hywel T. P. Williams, Nicola Perra +1
Co-authorship networks, where nodes represent authors and edges represent co-authorship relations, are key to understanding the production and diffusion of knowledge in academia. S…
COVID-19 is linked to changes in the time-space dimension of human mobility
Clodomir Santana, Federico Botta, Hugo Barbosa +3
Socio-economic constructs and urban topology are crucial drivers of human mobility patterns. During the coronavirus disease 2019 pandemic, these patterns were reshaped in their com…
Dynamic predictability and spatio-temporal contexts in human mobility
Bibandhan Poudyal, Diogo Pacheco, Marcos Oliveira +4
Human travelling behaviours are markedly regular, to a large extent, predictable, and mostly driven by biological necessities (\eg sleeping, eating) and social constructs (\eg scho…
Contrasting social and non-social sources of predictability in human mobility
Zexun Chen, Sean Kelty, Brooke Foucault Welles +3
Social structures influence a variety of human behaviors including mobility patterns, but the extent to which one individual's movements can predict another's remains an open quest…
Differences in the spatial landscape of urban mobility: gender and socioeconomic perspectives
Mariana Macedo, Laura Lotero, Alessio Cardillo +2
Many of our routines and activities are linked to our ability to move; be it commuting to work, shopping for groceries, or meeting friends. Yet, factors that limit the individuals'…
