Information Dynamics and Learning in Complex Adaptive Systems: Toward a Transdisciplinary Framework

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT This article develops a framework for understanding learning and adaptation in complex adaptive systems. Drawing from neuroscience, systems theory, information theory and quantum field theory, it examines how information processing, plasticity and systemic coherence emerge from distributed, nonlinear and feedback‐driven interactions. It argues

The Mediator's Mind: Navigating Party Psychology and Behavioural Dynamics in Dispute Resolution

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT Mediation increasingly requires psychological competence, as mediators regulate emotion, cognition and interaction within conflict systems. This study examines how mediators' psychological awareness and behavioural reflexivity shape conflict trajectories, advancing the concept of a behavioural architecture that transforms emotional volatility ...

Influence of natural fibers on physical, mechanical, and fire‐resistant properties of microconcrete

open access: yesStructural Concrete, EarlyView.
Abstract This study examined the influence of natural fibers on the physical, mechanical, and fire‐resistant properties of microconcrete, in comparison with conventional polypropylene fibers used in cement composites. The fibers were characterized by FTIR and TGA/DSC to assess their composition and thermal stability, and FTIR was also performed after ...

Moral Entrepreneurs of the Mastodon Migration

open access: yesSymbolic Interaction, EarlyView.
Social media platforms are imbued with politics and values through an interplay of coded architectures, platform policies, economic models, and algorithmic curation, together shaping and shaped by the activities of users. This dynamic set of relations is most evident during moments of disruption, in which platform politics and values come under debate.

Chronic Wasting Disease management responses in North America: A public policy analysis

open access: yesWildlife Society Bulletin, EarlyView.
In this study we use the Multiple Streams Framework from public policy theory to assess the responses of wildlife management agencies in states and provinces with CWD‐positive cases in the United States and Canada to alleviate public concerns and manage the spread of this disease.

Platinum Group Element Traces of CAMP Volcanism Associated With Low‐Latitude Environmental and Biological Disruptions

open access: yesGeophysical Monograph Series, Page 263-304., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Lightweight Convolutional Neural Networks Model and Data Augmentation‐Based Background Regression for Rail Surface Defect Detection

open access: yesArtificial Intelligence for Engineering, EarlyView.
An ultra‐lightweight semantic segmentation network RailNet with only 0.905 M parameters is proposed for rail surface defect detection. Combined with a CDBM image enhancement and GAN‐based data augmentation, RailNet achieves superior segmentation accuracy and real‐time speed on edge devices.

Recognition of Spatiotemporal Feature Images of Zero‐Sequence Voltage for Single‐Phase High‐Impedance Ground Faults Under Complex Conditions

open access: yesHigh Voltage, EarlyView.
ABSTRACT Diagnosing high‐impedance ground faults (HIGFs) in distribution networks is extremely challenging because high transition resistance significantly reduces electrical signal strength and unpredictable initial fault phase angles coupled with asymmetric voltage disturbances often lead to misclassification.
