On a modified version of Jensen inequality

Journal of Inequalities and Applications, 1999
The right-hand side of the Jensen inequality is multiplied by a constant and the related equation is considered. It is shown that every continuous solution of this equation is of the form for some , .

Endothermy, neuron counts, and other issues: Further remarks on neurocognitive evolution in fossil vertebrates

The Anatomical Record, EarlyView.
Abstract Last year, we challenged the view that large‐bodied theropod dinosaurs such as Tyrannosaurus rex resembled primates in cognition and behavior, a proposition made by Herculano‐Houzel in 2023. More recently, Jensen et al. have criticized our work on this topic, raising methodological and conceptual issues.

Asymptotic behavior of alternative Jensen and Jensen type functional equations

Bulletin des Sciences Mathématiques, 2005
Let \(X\) be a real normed space and \(Y\) be a real Banach space. A mapping \(A : X \to Y\) is called (i) alternative additive of the first form if \(A(x + y) + A(x - y) = -2A(-x)\); (ii) alternative additive of the second form if \(A(x + y) - A(x - y) = -2A(-y)\); (iii) alternative Jensen if \(A( - \frac{x + y}{2}) = - \frac{1}{2}(A(x) + A(y))\); (iv)

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

The Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Academic misconduct appeal services in China: Platform logics, self‐platformization and implications for integrity education

British Educational Research Journal, EarlyView.
Abstract Academic misconduct appeal services have quietly emerged within China's education marketplace, with commercial agencies promoting themselves on social media to assist international students facing misconduct hearings. While existing research on academic integrity has emphasized prevention and detection, far less attention has been paid to what

Does Managerial Ability Improve Environmental Performance and Overall ESG Ratings? The Impact of the European Sustainability Reporting Mandate

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines the role of managerial ability in driving environmental performance and overall environmental, social, and governance (ESG) ratings in the context of the European Union sustainability reporting regulations. Using a sample of 7242 firm‐year observations over the period 2015–2023, our results indicate a structural change in ...

Sobolev regularity via the convergence rate of convolutions and Jensen's inequality [PDF]

, 2007
We derive a new criterion for a real-valued function u to be in the Sobolev space W1,2(Rn). This criterion consists of comparing the value of a functional ¿ f(u) with the values of the same functional applied to convolutions of u with a Dirac sequence ...

Do Governance Structures Drive Green Building Adoption? A Machine Learning Approach With Random Forests

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 ...

Stability of a Jensen type functional equation

Banach Journal of Mathematical Analysis, 2007
The authors solve the following Jensen type functional equation \[ mf\left(\frac{x+y+z}{m}\right)+f(x)+f(y)+f(z)= n \left[ f\left(\frac{x+y}{n}\right) + f\left(\frac{y+z}{n}\right) + f\left(\frac{z+x}{n}\right)\right], \] where \(m\) and \(n\) are nonnegative integers with \((m,n)\neq (1,1)\).
