Some companion inequalities to Jensen's inequality [PDF]

Mathematical Inequalities & Applications, 2000
The authors obtain some new companion inequalities to Jensen's inequality (discrete or integral). The main results are given in a very general and abstract setting, for convex functions defined on an open convex set of a normed linear space. The differentiable cases, as well as sharpness questions are also considered.

What works in internal alternative provision? A salutogenic analysis

British Educational Research Journal, EarlyView.
Abstract Schools across England are setting up ‘internal alternative provision’ to meet the social, emotional and mental health needs of increasing numbers of pupils at risk of suspension, exclusion and absence. However, there is little guidance about what good practice looks like.

The Impact of Acquisition Intensity on ESG Performance

Business Strategy and the Environment, EarlyView.
ABSTRACT This study investigates the impact of Acquisition Intensity on ESG performance using a panel of 1,736 US‐listed companies from 2002 to 2023. Employing a robust OLS framework, we assess both Value‐Based and Volume‐Based Acquisition Intensity against overall ESG scores and their environmental, social, and governance pillars, controlling for firm

Stability Analysis of Integral Delay Systems with Multiple Delays

, 2015
This note is concerned with stability analysis of integral delay systems with multiple delays. To study this problem, the well-known Jensen inequality is generalized to the case of multiple terms by introducing an individual slack weighting matrix for ...

On Kedlaya type inequalities for weighted means [PDF]

, 2018
In 2016 we proved that for every symmetric, repetition invariant and Jensen concave mean $\mathscr{M}$ the Kedlaya-type inequality $$ \mathscr{A}\big(x_1,\mathscr{M}(x_1,x_2),\ldots,\mathscr{M}(x_1,\ldots,x_n)\big)\le \mathscr{M} \big(x_1, \mathscr{A ...

Exploring the Governance–Disclosure Nexus: Board Structures and ESG Disclosures in South Africa

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how governance structures such as board composition and board functions influence environmental, social and governance (ESG) reporting among listed South African firms. This study examines 90 public listed companies on the Johannesburg Stock Exchange between 2012 and 2022.

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

Subuniformity of harmonic mean p$$ p $$‐values

Canadian Journal of Statistics, EarlyView.
Abstract We obtain several inequalities on the generalized means of dependent p$$ p $$‐values. In particular, the weighted harmonic mean of p$$ p $$‐values is strictly subuniform under several dependence assumptions of p$$ p $$‐values, including independence, negative upper orthant dependence, the class of extremal mixture copulas, and some Clayton ...

New Estimations for Shannon and Zipf–Mandelbrot Entropies

Entropy, 2018
The main purpose of this paper is to find new estimations for the Shannon and Zipf–Mandelbrot entropies. We apply some refinements of the Jensen inequality to obtain different bounds for these entropies.
