Disentangling conservation asymmetries through socio‐economic transboundary factors across the Alto Paraná Atlantic Forest of South America

People and Nature, EarlyView.
Abstract Ecoregions are often defined based on homogeneous biophysical and ecological conditions and are optimal spatial units for designing conservation strategies. However, transboundary ecoregions such as the Alto Paraná Atlantic Forest (APAF) experience asymmetrical conservation outcomes, understood here as cross‐border differences, resulting from ...

Vector critical points and generalized quasi-efficient solutions in nonsmooth multi-objective programming

Journal of Inequalities and Applications, 2017
In this work, several extended approximately invex vector-valued functions of higher order involving a generalized Jacobian are introduced, and some examples are presented to illustrate their existences.

Relation of Bulk‐to‐Shear Loss Factors in Viscoelastic Auxetic Metamaterials

physica status solidi (b), EarlyView.
This article examines the dynamic behavior of isotropic auxetic viscoelastic materials, highlighting how negative Poisson's ratios affect energy dissipation, damping, and the interplay between bulk and shear moduli. By extending established viscoelastic theories to the auxetic range, it defines bound limits and underscores how dynamic Poisson's ratio ...

On Quasi-Monotone Stochastic Variational Inequalities with Applications

Axioms
This paper studies an efficient method for solving stochastic optimization problems formulated as stochastic variational inequalities with a quasi-monotone operator, where the cost function extends the classical monotone and pseudomonotone operators. Our

Distributed Optimization of Finite Condition Number for Laplacian Matrix in Multi‐Agent Systems

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper addresses the distributed optimization of the finite condition number of the Laplacian matrix in multi‐agent systems. The finite condition number, defined as the ratio of the largest to the second smallest eigenvalue of the Laplacian matrix, plays an important role in determining the convergence rate and performance of consensus ...

Some New Classes of Extended General Mixed Quasi-Variational Inequalities

Abstract and Applied Analysis, 2012
We consider and study a new class of variational inequality, which is called the extended general mixed quas-variational inequality. We use the auxiliary principle technique to study the existence of a solution of the extended general mixed quasi ...

Do Single‐Sex STEM Programs Have Merit? If So, for Whom, on What Measures?

Science Education, EarlyView.
ABSTRACT Single‐sex STEM programs—defined here as voluntary, gender‐segregated extracurricular or supplemental activities (e.g., summer camps, workshops, robotics clubs, internships, or citizen science initiatives)—have experienced heightened popularity and scrutiny amid efforts to increase diversity in STEM fields.

Including Social Nash Equilibria in Abstract Economies [PDF]

We consider quasi-variational problems (variational problems having constraint sets depending on their own solutions) which appear in concrete economic models such as social and economic networks, financial derivative models, transportation network ...

Cultural Differences and Interdependencies in Climate Change Mitigation Efforts and Their Psychological Antecedents Across 63 Countries

Sustainable Development, EarlyView.
ABSTRACT Climate change research, like much of social science, is biased toward WEIRD (Western, Educated, Industrialized, Rich, Democratic) populations, limiting its global relevance. Even cross‐national studies often suffer from methodological inconsistencies due to cultural and geographic interdependencies.

A note on quasi-monotone operators

International Journal of Mathematics and Mathematical Sciences, 1987
The treatment of nonlinear problems using a general framework is often a delicate issue. This is illustrated by the fact that the quasi-monotone operators of M. A. Noor are constant operators.
