Translating Circularity Into Strategy: A Governance Meta‐Capability Framework

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Firms struggle to transition to circular economy (CE) models, often citing external barriers. Yet some firms succeed, whereas others fail: Why? We argue that success depends on a specific governance capability—a meta‐capability that allows firms to (1) sense and strategically reframe CE imperatives, (2) seize opportunities by aligning diverse ...

Tensions of Sustainability Logics: Performance of a Company Utilizing a Sustainable Business Model

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT In recent years, companies have used sustainable business models to gain a competitive advantage. However, there are tensions due to the inconsistency between social, environmental, and economic logic in sustainable business models, making it difficult for companies to change. To understand the existing tensions and interactions between logics,

The damage and failure mechanism of prestatically loaded rock during medium‐strain rate cyclic impact loading

open access: yesDeep Underground Science and Engineering, EarlyView.
Based on experimental results and theoretical analysis, an established rock damage accumulation model that comprehensively considers the preapplied static load, impact peak value, impact frequency, and impact times. Abstract To study the rock damage mechanism under high static loading and superimposed medium strain rate cyclic impact loading, a series ...
