Reporting What Matters, or Reporting What Looks Good? Materiality and Balance in Post–Rana Plaza Apparel Sustainability Disclosure

Business Strategy and the Environment, EarlyView.
ABSTRACT Sustainability reports (SRs) are widely criticized for vague disclosures and selective emphasis on positive outcomes, yet systematic research on two core SR challenges remains limited: materiality (whether disclosed content is relevant) and balance (whether both achievements and challenges are reported).

Local Search and the Evolution of World Models

Topics in Cognitive Science, EarlyView., 2023
Abstract An open question regarding how people develop their models of the world is how new candidates are generated for consideration out of infinitely many possibilities. We discuss the role that evolutionary mechanisms play in this process. Specifically, we argue that when it comes to developing a global world model, innovation is necessarily ...

Self-loosening behavior of bolt in curvic coupling due to materials ratcheting at thread root

Advances in Mechanical Engineering, 2019
This article presents the bolt self-loosening mechanism in curvic coupling due to the structural ratcheting under cyclic loading. Finite element simulations are carried out under several loading conditions with different preloads and cyclic torque ...

Patents as Green Signals: Capital Market Responses to Corporate Green Innovation in Carbon‐ and Energy‐Intensive Firms

Business Strategy and the Environment, EarlyView.
ABSTRACT Adopting a signaling perspective, this study examines whether corporate green patenting reduces the cost of equity by mitigating information asymmetry in capital markets. Using longitudinal panel data from South Korea, we find that green patenting—encapsulating technological innovation related to energy, environmental protection, and climate ...

A Cyclic Constitutive Model Based on Fractional Derivative for Rate-Dependent Ratcheting of EA4T Axle Steel

Fractal and Fractional
Within the framework of elastoplastic theory, this study develops and improves a fractional cyclic constitutive model capable of describing rate-dependent ratcheting behavior by defining the ratcheting parameter as a function of the cumulative plastic ...

About the SBRA Method Applied in Mechanics of Continental Plates [PDF]

Transactions of the VŠB-Technical University of Ostrava, Mechanical Series, 2013
This article shows how the probabilistic SBRA (Simulation-Based Reliability Assessment) Method (i.e. stochastic Monte Carlo approach) is applied to the model of the behaviour of the lithosphere of the Earth (geomechanical model).

Conceptualizing Corporate Political Activity for Sustainability Governance—The CPA Cube

Business Strategy and the Environment, EarlyView.
ABSTRACT Sustainability transformations in the economy, and related public policy decisions, are highly contested, attracting business involvement. To better understand how business influence on government impacts the success or failure of sustainability governance efforts, this paper extends the literature on corporate political activity (CPA) by ...

Photoreversible Polyurea Actuators With Spatiotemporal Control and Adaptive Mechanics

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A light–thermal responsive polyurea network incorporating reversibly dimerizable anthracene units enables spatiotemporal modulation of cross‐linking density and nearly 400‐fold stiffness tuning. Integrating programmable anisotropy, photopatterning, self‐healing, and photowelding within a single framework, this bioinspired “one network–multifunction ...

Elastic Stress Ratcheting Assessment Considering Secondary Stress Due to Structural Discontinuity Effect

Applied Sciences
The partial secondary stress (hereinafter referred to as secondary mechanical membrane stress QL) generated by structural discontinuity effects is not considered by the current codes and standards and will lead to conservatism in stress analysis results.
