Purpose This study aims to identify and analyze the factors influencing social entrepreneurship in emerging destinations and to examine the relationships among these factors based on Isenberg's entrepreneurial ecosystem framework. Design/methodology/approach The research adopts a...

Behavioral manifestations of environmental alienation: a taxonomy of passive and destructive behaviors

To effectively address escalating environmental crises, it is crucial to understand the behavioral roots of human–environment disconnection; yet, the concept of Environmental Alienation (EA) remains empirically underdeveloped. This study introduces and empirically grounds the con...

Improvement in functional movement, landing mechanics, and dynamic balance following TRX training in physically active athletes after ACL reconstruction: a randomized controlled trial

Abstract Purpose Anterior cruciate ligament (ACL) rupture is one of the most prevalent and critical injuries experienced by athletes. The purpose of the present study was to examine the effects of a six-week TRX suspension training program on movement quality, landing mechanics,...

Beyond accuracy: interpretable behavioural profiling of children with ADHD using a visuospatial working memory game

Attention-Deficit/Hyperactivity Disorder (ADHD) is usually diagnosed using rating scales and clinical interviews, which offer limited access to underlying cognitive mechanisms. Existing objective tasks often rely on coarse summary statistics or less interpretable feature spaces,...

Effect of stainless steel 309 particulate reinforcement on the microstructure, porosity, hardness, and tribological properties of Al 6061-based composites

This study investigates characterization of Al6061-stainless steel 309 (SS) composites fabricated via powder metallurgy. The research focuses on optimizing the reinforcement volume percentage and milling duration to achieve superior microstructure, hardness, and tribological prop...

Numerical/experimental modeling of a residential CST system and performance evaluation using ray-tracing method

On the brink of an energy revolution the world is facing, Concentrated Solar Thermal (CST) systems have emerged as a promising solution to address the dual challenges of energy security and climate change. This study presents a novel approach involving numerical/experimental mode...

Numerical study of MRW-type unintegrated double parton distribution functions from non-factorized DPDFs

Abstract Double parton scattering provides a sensitive probe of multiparton correlations inside hadrons. In this work we present a numerical study of unintegrated double parton distribution functions constructed from non-factorized collinear DPDFs. As input we use the DPDFs and e...

Multi-objective siting-sizing for smart real-time coordinated flood management in mixed urban-natural watersheds

Population growth and urbanization have increasingly driven the expansion of urban areas into floodplains. To address this issue, detention basins provide a well-established approach for reducing flood risk while decreasing the need for costly upgrades to downstream stormwater co...

Processing-induced phase redistribution for enhanced self-corrosion control and discharge performance in Mg–Al–Mn anodes for Mg–air batteries

Abstract The long-term performance of Mg–air anodes in chloride electrolytes is governed by the interplay of phase architecture, self-corrosion, discharge-product evolution, and anodic utilization. This study elucidates the processing-dependent influence of Al in Mg–0.25Mn–xAl an...

Circular RNAs as regulators of epithelial‑mesenchymal transition in gliomas from molecular mechanisms to clinical applications

Epithelial–mesenchymal transition (EMT) is a fundamental biological process that drives glioma invasion, therapeutic resistance, and malignant progression. Recent evidence highlights circular RNAs (circRNAs) as pivotal post-transcriptional regulators that orchestrate EMT through...

Feed-forward lower extremity muscle activation and onset timing following functional fatigue during lateral hop landing

Abstract Background Fatigue-induced alterations in neuromuscular control may compromise dynamic ankle stability during landing tasks. However, limited evidence exists regarding the effects of fatigue on feed-forward lower-extremity muscle activation in athletes with different lev...

Behavioral and neural effects of right temporoparietal junction itbs during empathy processing in women

The right temporoparietal junction (rTPJ) is one neural region that has been implicated in empathy in previous studies. However, prior findings regarding its role have been inconsistent. Moreover, methodological limitations in earlier research, including the use of suboptimal emp...
