Business Strategy and the Environment, EarlyView.ABSTRACT This study examines the impact of independent female directors (IFDs) on green innovation (GI) among Chinese‐listed firms from 2008 to 2023. Additionally, we investigate the moderating effects of ownership structure and market competition on the relationship between IFD and GI.

Orthogonal generalized Lie bracket of triple derivations: properties and stability
Journal of Inequalities and ApplicationsIn this article, by using the concept of Jensen and additive mappings, we define the Jensen ρ-functional equation which preserves orthogonality, where ρ ≠ 0 , ± 1 $\rho \neq 0, \pm 1$ , and we show it to be orthogonally additive.

On a local form of Jensen's functional equation
Aequationes Mathematicae, 1985 A function f:(a,b)\(\rightharpoonup R\) is said to be locally Jensen at \(x\in (a,b)\) if there exists \(\delta >0\) such that (1) \(1/2(f(x+h)+f(x- h))=f(x)\) holds for ...

Takeover Vulnerability and the Discipline of ESG Overinvestment
Business Strategy and the Environment, EarlyView.ABSTRACT While takeovers serve a disciplinary role by replacing inefficient managers, the threat of takeovers may compel firms to divert attention from Environmental, Social and Governance (ESG) efforts as a strategic response to external pressure, especially when such firms are already overinvesting in ESG.

Business Strategy and the Environment, EarlyView.ABSTRACT This study examines the determinants of firms' propensity to adopt green buildings in the Euro Stoxx 300 and the S&P 500 indices, during 2012–2023. Using random forest binary classifiers, we assess the relative importance of financial, sectoral, geographic, and climate governance predictors and uncover nonlinear relationships often overlooked ...

On a General Functional Equation [PDF]
In this paper, we deal with a general functional equation in several variables. We prove the hyperstability of this equation in (m + 1)-normed spaces and describe its general solution in some special cases.

JENSEN'S FUNCTIONAL EQUATION IN MULTI-NORMED SPACES
Taiwanese Journal of Mathematics, 2010 Let \(E\) be a linear space and let \((F^n,\|\cdot\|_{n})_{n\in\mathbb{N}}\) be a multi-Banach space. In such a setting, the Hyers-Ulam stability of Jensen's functional equation is proved. Suppose that a mapping \(f: E\to F\) is an approximate solution of Jensen's equation, i.e., \(f(0)=0\) and, with some \(\alpha\geq 0\), \[ \sup_{k\in\mathbb{N ...
