Complex Firms, Controversial Outcomes: Global Evidence on ESG Failures and Remedies
Business Strategy and the Environment, EarlyView.ABSTRACT We examine whether business complexity increases firms' exposure to negative environmental, social, and governance (ESG) outcomes, specifically ESG controversies, using a global panel of firms from 37 countries over the period 2002–2021.

New Fractional Hermite–Hadamard–Mercer Inequalities for Harmonically Convex Function
Journal of Function Spaces, 2021 In 2003, Mercer presented an interesting variation of Jensen’s inequality called Jensen–Mercer inequality for convex function. In the present paper, by employing harmonically convex function, we introduce analogous versions of Hermite–Hadamard ...

MϕA-h-Convexity and Hermite-Hadamard Type Inequalities
International Journal of Analysis and Applications, 2022 We investigate a family of MϕA-h-convex functions, give some properties of it and several inequalities which are counterparts to the classical inequalities such as the Jensen inequality and the Schur inequality.

Operator inequalities related to weak 2-positivity [PDF]
, 2012 In this paper we introduce the notion of weak 2-positivity and present some examples. We establish some operator Cauchy--Schwarz inequalities involving the geometric mean and give some applications. In particular, we present some operator versions of Hua'

Bounds on the heat kernel of the Schroedinger operator in a random electromagnetic field
, 2006 We obtain lower and upper bounds on the heat kernel and Green functions of the Schroedinger operator in a random Gaussian magnetic field and a fixed scalar potential. We apply stochastic Feynman-Kac representation, diamagnetic upper bounds and the Jensen

The Burbea-Rao and Bhattacharyya centroids [PDF]
, 2011 We study the centroid with respect to the class of information-theoretic Burbea-Rao divergences that generalize the celebrated Jensen-Shannon divergence by measuring the non-negative Jensen difference induced by a strictly convex and differentiable ...

Existence of Full Replica Symmetry Breaking for the Sherrington–Kirkpatrick Model at Low Temperature
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT We verify the existence of full replica symmetry breaking (FRSB) for the Sherrington–Kirkpatrick (SK) model and determine the structure of its Parisi measure slightly beyond the high temperature regime. More specifically, we prove that the support of the Parisi measure for the SK model consists of an interval starting at the origin slightly ...

A Converse of the Jensen Inequality for Convex Mappings of Several Variables and Applications [PDF]
, 1999 In this paper we point out a converse result of the celebrated Jensen inequality for differentiable convex mappings of several variables and apply it to counterpart well-known analytic inequalities. Applications to Shannon's and Rényi's entropy mappings

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT The purpose of this study is to examine the relationship between board composition characteristics and ESG performance in companies from BRICS countries, and to assess how sector sensitivity moderates this relationship. A sample of 2045 BRICS companies was examined using panel data regression with random effects and logistic regression ...

Some Results on Pachpatte-Type of Opial Inequality
Pan-American Journal of Mathematics, 2022 This paper applies the modified Jensen inequality to generalize some cases of Pachpatte results of Opial-type inequalities on time scales. These inequalities further generalize some existing results.
