Simultaneous Generation of Topographic Models and Manning Roughness Coefficient Maps From Tri‐Stereoscopic Satellite Images: Application to the Huarmey River, Peru

open access: yesThe Photogrammetric Record, Volume 41, Issue 195, July‐September 2026.
Tri‐stereoscopic PeruSat‐1 imagery enables the simultaneous generation of 0.70 m‐resolution topography and spatially distributed Manning roughness maps, achieving 0.434 m vertical accuracy. Integrated into HEC‐RAS, these products provide consistent, high‐resolution inputs that improve hydraulic modelling and flood risk assessment in data‐scarce river ...

Implementation Punctuation: The Role of Feedback, Narratives, and Implementation in the Punctuated Equilibrium Theory

open access: yesPolicy Studies Journal, Volume 54, Issue 2, May 2026.
ABSTRACT Based on the Punctuated Equilibrium Theory (PET) and implementation research, this study proposes an extended conceptualization of policy punctuation that enables researchers to systematically include policy implementation as part of a punctuation. The key mechanisms underlying the PET, i.e., policy image and venue, information processing, and

Comparison of drone and ground surveys for the detection of a rare plant in a fragile ecosystem

open access: yesEcological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
We compared the accuracy, time, and financial costs of drone and ground surveys for the detection of wood lilies (Lilium philadelphicum) in an endangered alvar ecosystem. We found that the drone surveys detected 73%–78% of the plants found in the ground surveys, but that this type of survey was more expensive and time consuming than the ground survey ...

A low‐cost protocol for the optical method of vulnerability curves to calculate P50

open access: yesApplications in Plant Sciences, Volume 13, Issue 2, March-April 2025.
Abstract Premise The quantification of plant drought resistance, particularly embolism formation, within and across species, is critical for ecosystem management and agriculture. We developed a cost‐effective protocol to measure the water potential at which 50% of hydraulic conductivity (P50) is lost in stems, using affordable and accessible materials ...

Sensory processing across eating disorders: A systematic review and meta‐analysis of self‐report inventories

open access: yesInternational Journal of Eating Disorders, Volume 57, Issue 7, Page 1465-1488, July 2024.
Abstract Objective This review investigated the extant literature regarding the relationship between eating disorder diagnoses and sensory processing as measured by validated and reliable self‐report inventories. Increasing evidence highlights the role of sensory processing in cognitive functions.
