From Confusion to Clarity: A Multi‐Stage Process Framework for Understanding Consumer Confusion

Journal of Consumer Behaviour, EarlyView.
ABSTRACT This paper reconceptualizes consumer confusion as a multi‐stage temporal process rather than a static outcome, addressing theoretical fragmentation in existing antecedent‐consequence models. By integrating cognitive appraisal, contextual amplification, and adaptive coping within a unified framework, we explain how confusion unfolds rather than

National Context and STEM Career Expectations: Social Comparison and Gender Differences Across 72 Economies

The Career Development Quarterly, EarlyView.
ABSTRACT Adolescents’ career expectations play a pivotal role in shaping identity and future opportunities, yet little is known about how national‐level comparisons influence these expectations. Drawing on social comparison theory, this study examines how relative standing in science achievement, socioeconomic status (SES), and math self‐efficacy is ...

Niche partitioning in tenebrionid species (Coleoptera: Tenebrionidae) inhabiting Mediterranean coastal dunes

European Journal of Entomology, 2016
We analyzed the abundance, distribution and niche overlap of species (Pianka's Ojk index) in tenebrionid beetle communities inhabiting different biotopes in Tyrrhenian and Adriatic sand dunes.

The Rich Chemistry of Ionized Methanol With Sulfur Dioxide: Pathways to Prebiotic and Elusive Species in Earth's Atmosphere and Space

Chemistry – A European Journal, EarlyView.
The reaction between the methanol radical cation and sulfur dioxide is remarkably fast and forms several ionic and neutral products (HOSOH+, CH2OSO+, CH2OH+, CH2O, H2O, HSO2). The chemistry goes beyond simple proton or hydrogen transfer, revealing a close interaction between the two species, relevant to atmospheric and astrochemical environments where ...

Modeling proppant transport and settling in a 3D propagating fracture

Deep Underground Science and Engineering, EarlyView.
A versatile multiphysics tool is presented for simulating the complex processes involved in hydraulic fracturing treatments. The model couples fracture opening and propagation, variable‐density slurry flow, and proppant particle transport within the multiphysics object‐oriented simulation environment framework, based on two‐phase mixture equations and ...

Large eddy simulation of water flow over series of dunes

Water Science and Engineering, 2011
Large eddy simulation was used to investigate the spatial development of open channel flow over a series of dunes. The three-dimensional filtered Navier-Stokes (N-S) equations were numerically solved with the fractional-step method in sigma coordinates ...

Towards Transformative Climate Governance: Capacities and Constraints for Local Government in Aotearoa New Zealand

Environmental Policy and Governance, EarlyView.
ABSTRACT An emerging consensus calls for transformative climate governance. However, what instigates and sustains transformative pathways remains unclear. This study characterises the existence, quality and structural underpinnings of transformative governance capacities in local government climate change response in Aotearoa New Zealand, applying a ...

Dune Development Dominates Flow Resistance Increase in a Large Dammed River

Water Resources Research
Dunes are important for bedload transport in almost all large river systems and exert an important control flow resistance. Investigating dunes is fundamental for simulating discharge, sediment transport, and flood routing.

Unraveling the Interplay Between Collaborative Governance and Experimentation for Transformative Potential in Circular Water Systems: A Dutch Case Study

Environmental Policy and Governance, EarlyView.
ABSTRACT Freshwater availability is a critical climate change challenge in coastal delta regions. This challenge requires a transformative change toward circular water management. While experimentation and collaborative governance are recognized as enablers of transformative change, their interaction remains complex and insufficiently understood ...
