Business Strategy and the Environment, EarlyView.ABSTRACT The circular economy (CE) has become a major focus in energy and environmental (E&E) research, as it helps advance sustainable development, improve resource efficiency and alleviate environmental pressure. Even so, the literature is still fragmented, particularly in the CE themes it explores, the levels of analysis it adopts and the methods ...

Interaction of Anisotropic Dark Energy with Generalized Hybrid Expansion Law
Advances in High Energy Physics, 2022 Interaction of dark energy in the anisotropic locally rotationally symmetric (LRS) Bianchi type-I metric is investigated in the context of modified fR,T theory of gravity, where R is the Ricci scalar and T is the trace of stress energy momentum tensor ...

Hidden Markov graphical models with state‐dependent generalized hyperbolic distributions
Canadian Journal of Statistics, EarlyView.Abstract In this article, we develop a novel hidden Markov graphical model to investigate time‐varying interconnectedness between different financial markets. To identify conditional correlation structures under varying market conditions and accommodate shape features embedded in financial time series, we rely upon the generalized hyperbolic family of ...

Homogeneous anisotropic black branes with bianchi VI $$_h$$ h symmetry
European Physical Journal C: Particles and FieldsWe construct a new family of exact vacuum black brane solutions to five-dimensional Einstein gravity with a negative cosmological constant, characterized by a homogeneous horizon with Bianchi VI $$_h$$ h symmetry.

Cultural Pathways to Sustainability: How Organizational Cultures Shape Firms' ESG Performance
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Understanding how organizational culture shapes firms' environmental, social, and governance (ESG) performance is essential for advancing effective sustainability management. Culture reflects shared values and norms that shape how firms enact ESG principles.

Linear Perturbations of an Exact Gravitational Wave in the Bianchi IV Universe
UniverseThe proper-time method for constructing perturbative dynamical gravitational fields is presented. Using the proper-time method, a perturbative analytical model of gravitational waves against the backdrop of an exact wave solution of Einstein’s equations ...

Einstein - Weyl structures corresponding to diagonal Kähler Bianchi IX metrics [PDF]
Classical and Quantum Gravity, 1997 We analyse in a systematic way the four dimensionnal Einstein-Weyl spaces equipped with a diagonal Kähler Bianchi IX metric. In particular, we show that the subclass of Einstein-Weyl structures with a constant conformal scalar curvature is the one with a conformally scalar flat - but not necessarily scalar flat - metric ; we exhibit its 3-parameter ...

A Dynamic Business Modeling Approach to Port Sustainability: The Western Sicily Port Authority Case
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Ports are critical nodes in global trade and economic development, yet they generate substantial environmental and social externalities—including greenhouse gas emissions, air, noise, and water pollution, and adverse impacts on host communities—that demand integrated and forward‐looking governance.

Bianchi III and V Einstein metrics
, 2008 We present diagonal Einstein metrics for Bianchi III and V, both for minkowskian and euclidean signatures and we show that the Einstein Bianchi III metrics have an integrable geodesic flow.
