Prompting, Facilitating, and Legitimizing: How Work‐Life Flexibility Policies and Relational Others Shape Boundary Management

Human Resource Management, EarlyView.
ABSTRACT As hybrid working blurs boundaries between work and nonwork, it is critical we understand how these boundaries are negotiated by employees. Existing literature establishes that work‐life flexibility policies and relational others shape their boundary management, yet the mechanisms through which they do so remain underspecified.

Plastic luminescence in mechanoluminescent composites

InfoMat, EarlyView.
Through compression tests and numerical simulations, this study demonstrates that the luminescence of a mechanoluminescent (ML) composite is strongly associated with plastic strain, thereby providing new insight into deformation‐induced luminescence during the plastic stage.

Exposure–Recovery Approach for Hepatic Toxicity Analysis of Pyrethroid Lambda‐Cyhalothrin: Histopathological, Histochemical, and Biochemical Responses in Oreochromis niloticus

Journal of Applied Toxicology, EarlyView.
ABSTRACT Lambda‐cyhalothrin is a synthetic pyrethroid insecticide widely used in agriculture, but its potential to contaminate aquatic ecosystems and exert high toxicity on fish at low concentrations raises ecotoxicological concerns. While standard histopathological and biochemical assessments are common, the novel integration of pigment‐based ...

Targeting online sales through last‐mile delivery platform integration

Journal of Operations Management, Volume 71, Issue 2, Page 195-219, March 2025.
Abstract We analyze channel integration between a last‐mile delivery platform and a general merchandise retailer in two distinct stages: (1) platform delivery access (PDA), where the retailer continues to offer standard delivery through its own website but directs customers to the platform's website for new same‐day delivery; and (2) integrated ...
