Difference‐Making Under Metaphysical Indeterminacy
Philosophy &Public Affairs, EarlyView.ABSTRACT Many of the most pressing moral problems we face involve collective harms generated by large numbers of individually insignificant actions. Unlike triggering cases—where a threshold exists such that a single act could be decisive—non‐triggering cases lack any such sharp cutoff.

Regulation &Governance, EarlyView.ABSTRACT A recent raft of due diligence regulation (DDR) addressing social and environmental conditions in global value chains (GVCs) has spread across the UK and Europe. An emerging literature on DDR highlights the politics of its formation. Yet, we know little about how existing sustainability governance along GVCs interacts with DDR or the wider ...

The Earth's Greatest Porous Media
Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.Abstract How deeply does modern meteoric water circulate into the continental crust? How deep is the Earth's Critical Zone (CZ), the top layer of the continental lithosphere that co‐evolves with the atmosphere, hydrosphere, and biosphere, extending from vegetation canopy down to fresh bedrock and the base of active groundwater circulation?

Elastic-plastic finite element analysis of semi-hot forging dies
, 2009 Semi-hot or warm forging is an economical alternative to the conventional forging processes by combining advantages of hot and cold forging processes. In this study, a new forging process sequence and design of the preform die for a part which has been ...

Combined Surface Treatment of Forging Tools by Plasma Nitriding and PACVD
, 2022 S.373-383The lifetime of warm and hot forging tools is in comparison to other forming operations much lower because of the complex thermomechanical and tribological stress on the dies, punches and matrices.

How language divides: Asymmetries in the differentiating power of opinion discourse
Political Psychology, Volume 47, Issue 4, August 2026.Abstract Polarization is typically conceptualized as increasing distance between opposing attitudes. We argue instead that it unfolds through asymmetries in the group‐differentiating power of opinion language. In public discourse, actors use distinctive linguistic repertoires to signal alignment, mark boundaries, and render opinion landscapes ...
