Some companion inequalities to Jensen's inequality [PDF]

open access: yesMathematical 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.

A pipeline crisis or a sustainability crisis? Local and national succession planning for headteachers in England

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Recruiting and retaining school leaders is a challenge in many systems worldwide. Previous research has identified three distinct ways in which succession planning can be conceptualised and approached: a ‘pipeline’ approach seeks to match supply and demand for the posts that need filling; a ‘pool’ strategy involves proactively identifying and ...

What works in internal alternative provision? A salutogenic analysis

open access: yesBritish 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.

New Estimations for Shannon and Zipf–Mandelbrot Entropies

open access: yesEntropy, 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.

The Impact of Acquisition Intensity on ESG Performance

open access: yesBusiness 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

open access: yes, 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 ...

An operator inequality related to Jensen’s inequality [PDF]

open access: yesProceedings of the American Mathematical Society, 2001
Summary: For bounded non-negative operators \(A\) and \(B\), Furuta showed \[ 0\leq A \leq B \text{ implies } A^{\frac{r}{2}}B^sA^{\frac{r}{2}} \leq (A^{\frac{r}{2}}B^tA^{\frac{r}{2}})^{\frac{s+r}{t+r}}\quad (0\leq r, 0\leq s \leq t).
