Demonstration of a High‐Resolution Passive Profiler for Characterizing the Distribution of PFAS in Groundwater: A Comparison of Methods in the Field

Groundwater Monitoring &Remediation, EarlyView.
Abstract Characterizing the concentration and mass flux spatial distributions at sites with complex hydrogeologic conditions is critical to evaluate the fate and transport of contaminants, as well as to design effective remediation programs. PFAS (per‐ and polyfluoroalkyl substances)‐contaminated sites are even more complex due to the large number of ...

Thinking and Talking About War: How the Public in Six Countries Discusses the Outbreak of the War in Ukraine

JCMS: Journal of Common Market Studies, EarlyView.
Abstract The Russian aggression in Ukraine, launched on 24 February 2022, marked the return of conventional war in the European continent. While Western leaders have framed the ongoing conflict through a common narrative when speaking internationally, which varies in its national nuances, much less is known about the images and lenses that the European

Estimating National and Foreign Trade Elasticities Using Generalized Transport Costs

Journal of Regional Science, Volume 65, Issue 2, Page 471-496, March 2025.
ABSTRACT We introduce the definition of two distinct trade elasticities corresponding to imports from regions located in the same country (national elasticities) and foreign regions located in other countries (foreign elasticities). We resort to a three‐tier nested CES utility structure to derive the corresponding demand gravity equations.

The Impact of Autonomous Truck Technology on US Interstate Trade

Journal of Regional Science, EarlyView.
ABSTRACT Recent advances in autonomous and semi‐autonomous vehicle technologies promise substantial cost savings for goods shipped by truck. In this study, we quantify the impacts of these transport cost reductions on the US interstate trade using a structural gravity model of domestic trade. Based on projected cost savings from the widespread adoption

Cross‐Sectional Studies: Strengths, Limitations, and Methodological Considerations

Journal of Periodontal Research, EarlyView.
Cross‐sectional studies measure variables at a single time point to estimate prevalence and support descriptive epidemiology ‐ characterizing population health, tracking trends via repeated surveys – and for developing and validating screening instruments and diagnostic models.
