Functions Like Convex Functions
Journal of Function Spaces, 2015 The paper deals with convex sets, functions satisfying the global convexity property, and positive linear functionals. Jensen's type inequalities can be obtained by using convex combinations with the common center. Following the idea of the common center,

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 ...

Refinements of Jensen's inequality and applications
AIMS Mathematics, 2022 The principal aim of this research work is to establish refinements of the integral Jensen's inequality. For the intended refinements, we mainly use the notion of convexity and the concept of majorization.

Statistical properties of entropy production derived from fluctuation theorems
, 2010 Several implications of well-known fluctuation theorems, on the statistical properties of the entropy production, are studied using various approaches. We begin by deriving a tight lower bound on the variance of the entropy production for a given mean of

An interpolation of Jensen's inequality and its applications to mean inequalities
, 2018 In this paper, we show operator versions of the inequality due to Cho, Matić and Pečarić in connection to Jensen’s inequality for convex functions. As applications, we obtain an interpolation of the weighted arithmetic-geometric mean inequality for the ...

European Journal of Social Psychology, EarlyView.ABSTRACT This research investigates how political ideology shapes laypeople's evaluation of scientific studies examining cognitive differences between groups. In three experiments in Germany and the United States, participants evaluated identical research reports that varied only in the intergroup context—racial (Blacks/Whites) or ideological (liberals/

New bounds for Shannon, Relative and Mandelbrot entropies via Hermite interpolating polynomial
Demonstratio Mathematica, 2018 To procure inequalities for divergences between probability distributions, Jensen’s inequality is the key to success. Shannon, Relative and Zipf-Mandelbrot entropies have many applications in many applied sciences, such as, in information theory, biology

Mortality Forecasting Using Variational Inference
Journal of Forecasting, EarlyView.ABSTRACT This paper considers the problem of forecasting mortality rates. A large number of models have already been proposed for this task, but they generally have the disadvantage of either estimating the model in a two‐step process, possibly losing efficiency, or relying on methods that are cumbersome for the practitioner to use.
