Spatial inequalities in breastfeeding initiation in the United States: A multiscale analysis of county-level determinants
Deepening our understanding of geographic variations in breastfeeding initiation (BFI) remains an important element in developing a comprehensive snapshot of maternal and infant health. Identifying spatial variations in socioeconomic, demographic, cultural, and environmental barriers to breastfeeding can advance intervention efforts to educate and encourage breastfeeding within a community. The purpose of this paper is to provide a comprehensive …
Geoforensic Palynology Search Models and Human-Mediated Secondary Pollen Deposition
Forensic palynology involves using pollen on a person or object of interest or found at a crime scene to reconstruct history. Advances in genetic pollen identification techniques have spurred further research efforts in developing the geodatabases and models required to link those identified pollens to specific places or times. Many of these use plant species distribution models as a proxy for pollen presence in a landscape, an assumption that ho…

Spatial data uncertainty for location modeling: Ghost blocks and their implications
Census blocks are administrative units that serve as statistical areas for the decennial Census in the United States. Visible and nonvisible features bound blocks, including roads, railroads, streams, property lines, and city boundaries. The Census Bureau builds blocks using the Master Address File (MAF), which includes field-verified geographic information about the location of housing unit addresses. Unfortunately, there are substantial errors …
A deep dive into the collaborative networks of Yacht Rock
This paper explores the collaborative networks of Yacht Rock, a genre of music that emerged in the late 1970s and early 1980s and is currently experiencing a resurgence of popularity in the United States and beyond. In addition to using formal social network analysis to explore the development and transformation of Yacht Rock's collaborative musical network through time, we identify its most influential artists and musicians and highlight the mos…
A two-step process to increase successful geocoding in publicly available police stop data
Many police departments are meeting calls for transparency by releasing publicly accessible data. High-quality address locations are critical for successful and accurate geocoding, though the content and quality of that data can drastically vary across datasets. In this study, we showcase a two-step geocoding process that helps convert low-quality address locations into geo-locatable addresses using traditional geocoding and Jaro-Winkler edit dis…
Examining the relationship between contested edges and intergroup crime dynamics
Geoforensics with Pollen Quantification: A Spatial Perspective
Geoforensic science investigates the location and time of criminal occurrences by integrating multiple fields, including geography, criminology, ecology, biology, and geology. The ubiquity, durability, and spatial-temporal predictability make pollen a frequently used biomarker in geoforensic investigations to help determine the provenance of hard-to-trace items, including computers, counterfeit products, digging equipment, clothing, and undetonat…
California’s digital divide and the specter of data uncertainty for evaluating broadband coverage
A longitudinal analysis of broadband provision in tribal areas
Prostitution Arrest Spatial Forecasting in an Era of Increasing Decriminalization
There is ongoing debate regarding the merits of decriminalization or outright legalization of commercial sex work in the United States. A few municipalities have officially legalized both the selling and purchasing of sex, while others unofficially criminalize purchasing sex but have decriminalized its sale. In addition, there are many other locales with no official guidance on the subject but have unofficially decriminalized sex work by designat…

Google Fiber Community Connections: Promises, pitfalls, and outcomes in Austin, Texas
Community Connections is a program tied to Google Fiber that provides free gigabit fiber connections to public or nonprofit facilities such as schools, libraries, community centers, and municipal buildings, thereby presenting substantial opportunity to improve digital equity. In the case of Austin, Texas, applications for Community Connections were received and evaluated, and the winners forwarded to Google Fiber, where final decisions were made …
Data deluge or data trickle? Difficulties in acquiring public data for telecommunications policy analysis
There is a paucity of granular, high-resolution broadband data in the United States, which limits the prospects of informed telecommunications policy debates. In the absence of regulation requiring telecommunication providers to accurately report service footprints, pricing, and service quality data, providers refuse to disclose this information, routinely citing competition as the primary reason for keeping network and pricing data obfuscated. I…
Hurricane storm surge in Volusia County, Florida: Evidence of a Tipping Point for Infrastructure Damage
Storm surge often is the most destructive consequence of hurricanes and tropical storms, causing significant economic damage and loss of life. Many coastal communities that are located in high-risk areas vis-à-vis hurricanes and tropical storms are prepared for moderate (between six and eight feet) storm surges. Such preparation, though, is not commensurate with more severe, but less frequent, storm surges (greater than eight feet). These gaps in…
Predicting Movement of Homeless Young Adults: Artificial Neural Networks and Generalized Linear Models
Objective: Previous research has indicated high rates of intercity movement among homeless young adults (HYAs) for a variety of prosocial (e.g., avoiding domestic violence and seeking new employment opportunities) and antisocial (e.g., following drug supplies and avoiding law enforcement) reasons. The complicated mixture of individual circumstances associated with transience has made it difficult to predict features of transience, such as distanc…
Predicting geographic transience in homeless young adults across three U.S. cities: Who are these frequent flyers and distance travelers
Prior research reveals high rates of geographic mobility (i.e., transience) among homeless young adults (HYAs). Yet to date, little is known about predictors of different aspects of their transience as well as characteristics of the most highly transient HYAs. This study thus used the risk/resilience framework to identify predictors of three measures of HYAs’ transience (i.e., number of intercity moves, total distance traveled, and average distan…
