Biological Reviews, EarlyView.ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Journal of Applied Philosophy, EarlyView.ABSTRACT This article identifies assistive technologies (ATs) as ‘pre‐technologies’ mediating access to other technologies for disabled subjects (DSs). The motivation is to show that without ATs, DSs cannot be said to have the same level of access to freedom and self‐forming activities as able‐bodied subjects.

Systems of reciprocity in human–ocean relationships: Across time, place, language and culture
People and Nature, EarlyView.Abstract In the face of large‐scale marine environmental challenges, solutions that meaningfully capture the complexity of socio‐cultural and economic factors contributing to such issues—and their solutions—are urgently needed. This scoping review explores examples of reciprocity in human–ocean relationships to inform the conceptual underpinning and ...

Polymer Composites, EarlyView.Experimental and numerical investigation on impact‐tolerance efficient evaluation of soft TPU composites. ABSTRACT This study combines experimental characterization and numerical modeling to investigate the impact behavior of aramid fiber–reinforced composites incorporating a thermoplastic polyurethane (TPU) matrix. Low‐velocity impact (LVI) tests were
