Associations Between Severe Food Insecurity and Food Addiction in Brazilian Low‐Income Women

open access: yesEuropean Eating Disorders Review, EarlyView.
ABSTRACT Objective The present study aims to assess the distribution of food addiction (FA) across different levels of food insecurity (FI) in Brazilian women of reproductive age living in poverty, and to investigate the association between FA and FI. Method This is a cross‐sectional study conducted between October 2020 and May 2021 in 40 urban favelas

Statistical properties of entropy production derived from fluctuation theorems

open access: yes, 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

ESG Performance and Credit Risk: Evidence From Chinese Manufacturing Companies

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT This study investigates the effect of corporate environmental, social, and governance (ESG) performance on credit risk using a sample of manufacturing firms listed on China's Shanghai and Shenzhen A‐share markets from 2009 to 2021. Employing fixed effects, the generalised method of moments, and instrumental variable models, we find that ...

The Hadamard Determinant Inequality - Extensions to Operators on a Hilbert Space

open access: yes, 2017
A generalization of classical determinant inequalities like Hadamard's inequality and Fischer's inequality is studied. For a version of the inequalities originally proved by Arveson for positive operators in von Neumann algebras with a tracial state, we ...

Inconsistency of the Capital Asset Pricing Model in a Multi‐Currency Environment

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT The capital asset pricing model (CAPM) is a widely adopted model in asset pricing theory and portfolio construction because of its intuitive nature. One of its main conclusions is that there exists a global market portfolio that each rational investor should hold in proportion to the risk‐free asset. In this paper, we demonstrate theoretically

Improved Hermite–Hadamard Inequality Bounds for Riemann–Liouville Fractional Integrals via Jensen’s Inequality

open access: yesFractal and Fractional
This paper derives the sharp bounds for Hermite–Hadamard inequalities in the context of Riemann–Liouville fractional integrals. A generalization of Jensen’s inequality called the Jensen–Mercer inequality is used for general points to find the new and ...

Application of Functionals in Creating Inequalities

open access: yesJournal of Function Spaces, 2016
The paper deals with the fundamental inequalities for convex functions in the bounded closed interval. The main inequality includes convex functions and positive linear functionals extending and refining the functional form of Jensen’s inequality.

CSR disclosure and investment efficiency in MENA countries: The moderating role of CSR committee

open access: yesStrategic Change, EarlyView.
ABSTRACT Corporate social responsibility disclosure (CSRD) is often recognized as a transparency mechanism that allows companies to communicate their commitment to CSR. However, CSRD may also exacerbate agency conflicts. This study addresses these two contrasting perspectives by investigating the impact of CSRD on investment efficiency and exploring ...

Fractional Power Control for Decentralized Wireless Networks

open access: yes, 2007
We consider a new approach to power control in decentralized wireless networks, termed fractional power control (FPC). Transmission power is chosen as the current channel quality raised to an exponent -s, where s is a constant between 0 and 1.

Overexploitation can counteract top‐down control and the paradox of enrichment in simple food chains

open access: yesOikos, EarlyView.
Because of its high abundance or its high feeding intensity, a consumer can overexploit its resource by consuming it on a shorter timescale than resource regeneration. While this short‐term overexploitation is widespread in nature, its general implications for biotic control patterns and ecosystem stability are not clear.
