When Politics Shapes Administration: Bureaucratic Autonomy, Policy Role Separation, and Organizational Capacity in an Institutionally Weak Public Administration

Public Administration and Development, EarlyView.
ABSTRACT This study examines the impact of administrative autonomy and the separation of roles in public policy on organizational capacity within hybrid public administration systems, particularly in Colombia. It explores the dynamics between elected officials and civil servants, focusing on how the division of responsibilities and the autonomy granted

The impact of COVID‐19 on public perceptions of wild meat in Central Africa

People and Nature, EarlyView.
Abstract Wild meat is a significant source of food and income generation in Central Africa. However, there is little knowledge of how the assumed link between COVID‐19 and wild meat consumption has been discussed by the media and received by the public. In this study, we conducted media content analysis of 264 articles published in 2019–2020 related to

Effects of Polyamide‐6 Bulk Plasma Treatment on Morphology, Crystallinity and Mechanical Properties of Microfibrillar Composites

Polymer Composites, EarlyView.
Microfibrillar composite containing highly oriented, plasma‐treated PA6 microfibrils embedded within the polymer matrix. ABSTRACT Plasma treatment is often used to alter chemical surface characteristics of fibers or polymers, improving dispersion of components and interfacial adhesion between incompatible constituents in composites.

A Self‐Supervised Machine Learning Approach for the Estimation of Open‐Circuit Voltage Degradation in Photovoltaic Systems

Progress in Photovoltaics: Research and Applications, EarlyView.
This study introduces a self‐supervised machine learning approach integrating physics‐based principles to estimate open‐circuit voltage (voc$$ {v}_{oc} $$) degradation in photovoltaic systems using SCADA data. By combining clustering and regression algorithms, our method detects performance deviations without labelled datasets.

Psychological Impacts of a Teacher Mindfulness‐Based Program: Moderation by Changes in Neuroendocrine Stress Over Time

Psychology in the Schools, EarlyView.
ABSTRACT This study extends previous research on a Mindfulness Based Program (MBP) for teachers by examining whether psychological impacts of MBP participation were moderated by changes in teachers' neuroendocrine stress across the program. Teachers (n = 60, 54 women) were randomly assigned to MBP or waitlist control conditions and assessed at pre ...

Turbulent snow transport and accumulation: New reduced‐order models and diagnostics

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Our new reduced‐order models of snow particle transport provide high‐fidelity calculations of snow accumulation in turbulent flows at significantly reduced computational costs. Additional accumulation diagnostics from the reduced‐order model predict complex patterns of particle concentration in turbulent boundary layers via coherent flow structures in ...

A composite‐loss graph neural network for the multivariate post‐processing of ensemble weather forecasts

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The dual graph neural network (dualGNN), trained with a composite loss combining the energy score (ES) and variogram score (VS), consistently outperformed models optimized solely for ES or the continuous ranked probability score in the multivariate setting, as well as empirical copula approaches.

Real‐Time Terrain Traversability Analysis and Mapping for Autonomous Robotics in Dynamic Environments: Fusing Appearance‐ and Geometry‐Based Approaches

Journal of Field Robotics, EarlyView.
ABSTRACT This paper presents advanced methodologies for real‐time terrain analysis and mapping in autonomous robotic systems. The focus is on appearance‐based terrain traversability analysis and geometric‐based terrain traceability analysis. In the appearance‐based approach, an enhanced segmentation model using pixel‐based augmentation and 13 unique ...

Potential Impacts of Low Flows on Fish Foodscapes and Production in a Braided River

River Research and Applications, EarlyView.
ABSTRACT Changes in river discharge affect the physical composition and connectivity of habitats which, in turn, may shape the spatial distribution of fish food abundance, accessibility and quality—the ‘foodscape’—of river ecosystems. However, the influence of river flows on fish foodscapes has received very little attention from scientists. We studied
