Generalizations of Shannon type inequalities via diamond integrals on time scales

open access: yesJournal of Inequalities and Applications, 2023
The paper generalizes Shannon-type inequalities for diamond integrals. It includes two-dimensional Hölder’s inequality and Cauchy–Schwartz’s inequality, which help to prove weighted Grüss’s inequality for diamond integrals.

Comments on Jensen’s Inequalities

open access: yesMalaya Journal of Matematik, 2014
The paper gives generalizations of some Jensen type inequalities for convex functions of one variable. The work is based on the methods which use convex combinations in deriving inequalities. The main inequality is applied to the quasi-arithmetic means.

On a Jensen-Mercer operator inequality [PDF]

open access: yesBanach Journal of Mathematical Analysis, 2011
We give a general form of the Jensen-Mercer operator inequality for convex functions and its refinement for operator convex functions, continuous fields of operators and unital fields of positive linear mappings. As consequences, we obtain a global upper bound for the Jensen's operator functional, and some properties of the quasi-arithmetic operator ...

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.

Bridging the Gap: Student Voices on Recruitment and Retention in Ecology

open access: yesThe Bulletin of the Ecological Society of America, EarlyView.
Abstract Students entering ecology and environmental science face a variety of challenges, including limited awareness of career paths, lack of mentorship, and difficulties connecting with peers and faculty. These challenges are often amplified for students from marginalized backgrounds, who may also encounter microaggressions, underrepresentation, and

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

open access: yesBusiness 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.

A Refinement of Jensen’s and Minkowski’s Inequalities via Superquadratic Functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences
We provide in this note a different refinement of Jensen’s inequality obtained via superquadratic functions. A refinement of Minkowski’s and Hölder’s inequalities is also established as an application of our refined Jensen’s inequality.

Complex Firms, Controversial Outcomes: Global Evidence on ESG Failures and Remedies

open access: yesBusiness 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.
