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.

On Quadratic g-Evaluations/Expectations and Related Analysis [PDF]

open access: yes, 2008
In this paper we extend the notion of g-evaluation, in particular g-expectation, to the case where the generator g is allowed to have a quadratic growth.

Some inequalities for operator (p,h)-convex functions

open access: yes, 2017
Let $p$ be a positive number and $h$ a function on $\mathbb{R}^+$ satisfying $h(xy) \ge h(x) h(y)$ for any $x, y \in \mathbb{R}^+$. A non-negative continuous function $f$ on $K (\subset \mathbb{R}^+)$ is said to be {\it operator $(p,h)$-convex} if \begin{

A Framework for Understanding and Evaluating Localization: The Case of HelpAge International

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT Many transnational non‐governmental organizations (TNGOs) are reevaluating their organizational forms and norms as they pursue localization. Localization itself is a contested and multifaceted concept, however, complicating the design, implementation, and evaluation of localization efforts.

Generalized integral Jensen inequality

open access: yesJournal of Inequalities and Applications
In this paper we introduce necessary and sufficient conditions for a real-valued function to be preinvex. Some properties of preinvex functions and new versions of Jensen’s integral type inequality in this setting are given.

Around Jensen's inequality

open access: yesDemonstratio Mathematica, 1994
Let \(\tau\) be a normal semifinite trace on a von Neumann algebra \(A\), let \(\alpha: A\to A\) be a positive linear contraction and let \(a= a^*\in A\). If \(f\) is a continuous convex function defined on the spectrum of \(a\), then it is shown that if \(\tau(\alpha(f(a))_+)< \infty\) then either \(\tau((f(\alpha(a)))_+)< \infty\) or \(\tau((f(\alpha(

Policy Capacity for Novel Technology Adoption: Developmental Insights From Singapore's AI Adoption in Long‐Term Care

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT Worldwide, artificial intelligence‐driven technologies, including robotics and autonomous systems (RAS), are adopted to address manpower shortages in long‐term care. However, their effective use requires a reasonable degree of policy capacity across individual‐, organisational‐ and system‐levels.

Capacity and limitations of US wild meat donation programmes

open access: yesPeople and Nature, EarlyView.
Abstract Historically, sharing of wild harvests to facilitate food security followed concepts of kin selection and reciprocal altruism. However, cultural shifts have reduced access to foods for some populations in modern times. Cultural altruism through sustainably harvested wild meat donation programmes (WDPs) can reduce food and nutritional ...

Generalized Jensen-Mercer Inequality for Functions with Nondecreasing Increments

open access: yesAbstract and Applied Analysis, 2016
In the year 2003, McD Mercer established an interesting variation of Jensen’s inequality and later in 2009 Mercer’s result was generalized to higher dimensions by M. Niezgoda. Recently, Asif et al.

Generalized Niezgoda's Inequality with Refinements and Applications [PDF]

open access: yesSahand Communications in Mathematical Analysis
Motivated by the results of Niezgoda, corresponding to the generalization of Mercer's inequality for positive weights, in this paper, we consider real weights, for which we establish related results.
