OUT OF TIME? Chronocracy and Ageism in Brexit–COVID‐19 England
Cultural Anthropology, Volume 41, Issue 2, Page 193-217, May 2026.ABSTRACT Generation or relative age is a common way humans define social difference. In Europe and North America, old age is frequently perceived as a period of decline and loss, a condition “successful aging” paradigms exhort individuals to avoid for as long as possible. Explicit and implicit ageist beliefs, discourses, and practices marginalize later

Energy Science &Engineering, Volume 14, Issue 4, Page 1864-1880, April 2026.This study reveals the temporal and spatial evolution law of roof separation under the karst aquifer and the dynamic water inrush mechanism of roof separation. The FAHP–EWM–CRITIC combination weighting method was established to obtain the risk zoning of bed separation water inrush in a karst landform mining area. ABSTRACT Coalfields in northern Guizhou

L2-norm deformation phase unwrapping in mining area driven by matrix pencil model
Meikuang AnquanTo address the limitations of traditional phase unwrapping (PU) approaches in differential interferometric synthetic aperture radar (DInSAR) technology which performs poorly in unwrapping low-coherence deformation interferograms in mining areas, an L2 ...

Energy Science &Engineering, Volume 14, Issue 4, Page 1881-1902, April 2026.This work reveals the “C‐Y,” double “Y,” “π,” and “Y” fracture modes of thick, hard strata and their progressive breaking process (O‐F‐R/S mode), providing a theoretical basis for controlling strong ground pressure in deep mining. ABSTRACT In response to the dynamic hazards caused by the fracture of thick‐hard strata in deep mining, this study ...
