How geography influences access to different types of healthcare

Posted on

This new editorial in Sleep Health  showcases how an interdisciplinary approach to thinking about how geography influences access to different types of healthcare. Co-authored by Soomi Lee, Christopher N. Kaufmann, Catherine A. Lippi, Sadie J. Ryan and Yi Guo, the editorial discusses how this approach impacts diagnostic outcomes for sleep problems,  which may be indicators […]

Mobility disruption and recovery in SW Florida’s elderly-dense communities during Hurricane Ian

Posted on

Hurricane Ian, a Category 4 storm that struck Florida’s southwest coast, resulted in 156 fatalities, with two-thirds of the victims being seniors. This highlights the need to address disaster risks for this vulnerable population. This study utilizes anonymized and privacy enhanced mobile phone GPS data to examine mobility disruptions and recovery patterns during Hurricane Ian […]

The COVID-19 Impact on Spatiotemporal Dynamics of US Domestic Migration

Posted on

Understanding the impacts of the COVID-19 pandemic on domestic migration patterns is crucial for addressing resource needs and migration forecasting. Only a limited number of studies, however, have explored these dynamics through the lens of network analysis. Using Internal Revenue Service (IRS) county-to-county migration data, this article conceptualizes the U.S. domestic migration system as complex […]

Mapping large-scale brand networks: A consumers’ foot traffic-based approach

Posted on

How do brands interact? Commercial brands are increasingly interconnected, forming a complex network. Analyzing brand networks is crucial to understanding brand interactions and developing data-driven marketing strategies. Traditional methods utilize consumer behavior surveys and social media databases to construct brand networks, but few have considered consumers’ spatial mobility – their movements between brand points of […]

The Vanishing Green: How AI is Uncovering Dhaka’s Struggle with Air Pollution and Urban Growth

Posted on

Dhaka, one of the fastest-growing megacities in the world, is a place of constant movement, rapid expansion, and an ever-changing skyline. But beneath the rising high-rises and congested streets, something has been quietly disappearing—the city’s green spaces. Trees, parks, and natural buffers are being lost to unplanned urbanization, and with this loss comes a rise […]

47 Years of large Antarctic calving events

Posted on

In Antarctica, massive icebergs are a consequence of calving, where blocks of ice detach from the continent’s ice shelf. The calving of these massive icebergs is a rare occurrence with unpredictable variability, making it a difficult process to understand and statistically model. Here, we study calving using a statistical method called extreme value theory (EVT), […]

New data tool tracks political violence in Africa

Posted on

Political violence is very irregularly distributed across time. Periods of relative calm are often followed by massive waves of attacks. Violent events are relatively rare, sparse and concentrated, making it difficult to evaluate whether violence is actually increasing or decreasing. To overcome these limitations, UF Geography Associate Professor Olivier Walther developed a new dashboard in […]
