A Review of the Evolution of Research on the Size of Children's Drawings in Relation to Their Expressed Emotion About the Depicted Topic: 1988–2023

International Journal of Art &Design Education, EarlyView.
Abstract This narrative review examines the relationship between the size of children's drawings and their expressed emotions about the depicted subjects, focusing on research conducted between 1988 and 2023. The studies are presented chronologically to demonstrate how researchers have progressively addressed methodological challenges identified in ...

Some variants of Ćirić’s multi-valued contraction principle

Annals of the West University of Timisoara: Mathematics and Computer Science, 2019
In this article, a study of the fixed point problem for Ćirić type multi-valued operators is presented. More precisely, some variants ofĆirić’s contraction principle for multi-valued operators, as well as a strict fixed point principle forĆirić type ...

A Volterra functional-integral equation, via weakly Picard operators technique [PDF]

Carpathian Journal of Mathematics, 2014
In this paper we consider a Volterra functional-integral equation with linear modifications of the arguments. We use weakly Picard operators’ technique and we obtain existence and data dependence results for the solutions.

Unequal Solidarity: Club Rules and Crisis Support in the European Polity

JCMS: Journal of Common Market Studies, EarlyView.
Abstract Is European solidarity during crises due to common or close identities? Or do Europeans punish rule‐breaking countries by showing them less solidarity? Research on the determinants of European solidarity increasingly focuses on ‘solidarity to’, how givers' attitudes are shaped by their perceptions of receiving member states.

Modular forms, hypergeometric functions and congruences

, 2013
Using the theory of Stienstra and Beukers, we prove various elementary congruences for the numbers \sum \binom{2i_1}{i_1}^2\binom{2i_2}{i_2}^2...\binom{2i_k}{i_k}^2, where k,n \in N, and the summation is over the integers i_1, i_2, ...i_k >= 0 such that ...

Differential equations with modified argument, via weakly Picard operators’ theory [PDF]

Carpathian Journal of Mathematics, 2013
In this paper we use Picard and weakly Picard operators technique, introduced by Ioan A. Rus, to study a class of differential equations with modified argument and a boundary value problem for this kind of equations. We obtain existence, uniqueness, comparison and data dependence results.

The Core‐Periphery Model Under Additively Separable Preferences

Journal of Regional Science, Volume 65, Issue 2, Page 378-402, March 2025.
ABSTRACT This paper reexamines Krugman's core‐periphery model by substituting his constant elasticity of substitution (CES) utility with a general additively separable utility that comprehensively captures the pro‐competitive effect while preserving the income effect.

Endogenous Distress Contagion in a Dynamic Interbank Model: How Possible Future Losses May Spell Doom Today

Mathematical Finance, EarlyView.
ABSTRACT We introduce a dynamic and stochastic interbank model with an endogenous notion of distress contagion, arising from rational worries about future defaults and ensuing losses. This entails a mark‐to‐market valuation adjustment for interbank claims, leading to a forward‐backward approach to the equilibrium dynamics whereby future default ...

The Theory of Reich's Fixed Point Theorem for Multivalued Operators

Fixed Point Theory and Applications, 2010
The purpose of this paper is to present a theory of Reich's fixed point theorem for multivalued operators in terms of fixed points, strict fixed points, multivalued weakly Picard operators, multivalued Picard operators, data dependence of the fixed ...

Canonical and non‐canonical functions of proteins regulating mitochondrial dynamics in mammalian physiology

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.
