Pollution and Haunted Eco‐Histories: Silent Hill and Silent Horrors in Centralia, Pennsylvania
Popular Culture Review, Volume 37, Issue 2, December 2026.ABSTRACT Centralia is a former mining town and borough in Northeastern Pennsylvania, whose population has been steadily declining since the Mine Fire of 1962—a fire that still burns today. The “horrors” of living in Centralia are reflected in horror media set in postindustrial mining towns like Silent Hill.

Energy Science &Engineering, Volume 14, Issue 8, Page 3625-3637, August 2026.This study primarily investigates the optimal width for coal pillar retention in both sides of the worked‐out face section. Taking the 42201 haulage roadway of the 42201 working face at Shengxin Coal Mine as the primary research target, it analyses the optimum width for coal pillar retention through theoretical calculations, numerical simulations, and ...

Energy Science &Engineering, Volume 14, Issue 8, Page 3935-3947, August 2026.Mining disturbance tends to trigger fault stick‐slip instability and induce disasters. This paper establishes a mechanical model to propose a critical criterion, which is verified to be reliable via FLAC3D, providing a theoretical basis for early warning of fault slip disasters.

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.Abstract The Kentland Impact Structure is a classic complex crater whose central peak is exposed in an active quarry in NW Indiana, USA. However, its diameter has remained poorly constrained due to the thick glacial sediment cover. Newly obtained seismic reflection profile images combined with refraction seismic tomography, earlier gravity surveying ...

Making the Intangible Tangible: Organizational Capital and Stock Liquidity
British Journal of Management, Volume 37, Issue 3, July 2026.Abstract We propose an intangibility‐driven stock liquidity hypothesis and explore the role of organizational capital in influencing stock liquidity. Using a sample of 42,682 firm‐year observations, we uncover compelling evidence that firms' intangible organizational capital boosts stock liquidity.
