Modeling and parameter estimation for fractional large‐scale interconnected Hammerstein systems
Asian Journal of Control, EarlyView.Abstract This paper addresses the challenge of modeling and identifying large‐scale interconnected systems exhibiting memory effects, hereditary properties, and non‐local interactions. We propose a fractional‐order extension of the Hammerstein architecture that incorporates Grünwald–Letnikov operators to capture complex dynamics through multiple ...

Business Strategy and the Environment, EarlyView.ABSTRACT This study examines corporate environmental reporting practices among listed companies in the European Union during the period 2018–2022, within the context of the Non‐Financial Reporting Directive (NFRD). To this end, an Environmental Disclosure Index (EDI) is constructed based on qualitative reporting items, and panel‐data models are ...

Business Strategy and the Environment, EarlyView.ABSTRACT Drawing on dynamic capabilities view and upper echelons theory, this study shows how energy‐sector SMEs convert dynamic capabilities into green competitive advantage. We theorize that sensing–seizing–reconfiguring routines are associated with green competitive advantage only when top managers visibly prioritize environmental goals and foster a

Smart Cities Leading the Green Transition: Linking Open Innovation and Entrepreneurial Dynamics
Business Strategy and the Environment, EarlyView.ABSTRACT Smart cities today are vibrant spaces where technology, collaboration, and sustainability come together to shape a better future. The green transition in cities is not just about building greener infrastructure or cutting emissions. It also changes how people, institutions, and businesses think and act.
