Generalized Jensen and Jensen–Mercer inequalities for strongly convex functions with applications
Journal of Inequalities and ApplicationsStrongly convex functions as a subclass of convex functions, still equipped with stronger properties, are employed through several generalizations and improvements of the Jensen inequality and the Jensen–Mercer inequality.

A variational perturbation scheme for many-particle systems in the functional integral approach
, 2000 A variational Perturbation theory based on the functional integral approach is formulated for many-particle systems. Using the variational action obtained through Jensen-Peierls' inequality, a perturbative expansion scheme for the thermodynamic potential

Overexploitation can counteract top‐down control and the paradox of enrichment in simple food chains
Oikos, 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 Jensen’s type inequalities via generalized majorization inequalities
Filomat, 2018 In this paper, we give generalizations of Jensen?s, Jensen-Steffensen?s and converse of Jensen?s inequalities by using generalized majorization inequalities. We also present Gr?ss and Ostrowski-type inequalities for the generalized inequalities.

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

Public 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
People 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 ...

On constrained annealed bounds for pinning and wetting models
, 2005 The free energy of quenched disordered systems is bounded above by the free energy of the corresponding annealed system. This bound may be improved by applying the annealing procedure, which is just Jensen inequality, after having modified the ...
