Optimization of Blasting‑Induced Roof Cutting Parameters in Key Stratum and Its Application in Gob‑Side Entry Retention Technology

Energy Science &Engineering, EarlyView.
This study addresses hard roof coal seam conditions by optimizing key stratum blasting‐cutting parameters through theoretical analysis, numerical simulation, and field tests. It proposes calculation methods for blast hole spacing and delay timing based on stress wave theory, controlling roadway deformation within 35 mm, thereby enhancing resource ...

Justice for biodiversity: an X‐curve transformation pathway for a sustainable future

Frontiers in Ecology and the Environment, EarlyView.
Decades of conservation action have failed to stem biodiversity loss, stimulating heated debates over which conservation strategies are the most effective. Do we focus on preserving sufficient wilderness, maintaining services from nature for societal well‐being, or protecting vulnerable socioecologies from injustice?

Operating in perpetual motion? Coping with the dark side of global boundary spanning

Global Strategy Journal, EarlyView.
Abstract Research Summary This paper explores how individuals experience and cope with the demands of global boundary spanning in multinational enterprises (MNEs). We foreground temporary colocation as a modality through which mobile global boundary spanners repeatedly traverse multiple boundaries, triggering intense demands with adverse consequences ...

Waiting Time Prioritisation for Public and Private Providers: Evidence From Hip Replacement Surgery

Health Economics, EarlyView.
ABSTRACT Waiting times for planned health care treatments have been increasing in England and other OECD countries. One policy to reduce the impact of waiting times on patients' health is for doctors to prioritise patients according to their health status. This study tests the extent to which publicly‐funded patients in poorer health are prioritised on
