Attainability to Solve Fractional Differential Inclusion on the Half Line at Resonance

Complexity, 2020
The presented article is deduced about the positive solutions of the fractional differential inclusion at resonance on the half line. The fractional derivative used is in the sense of Riemann–Liouville and the problem is supplemented by unseparated ...

A Curated Review of ESA Publications for Teaching Ecology

The Bulletin of the Ecological Society of America, Volume 107, Issue 3, July 2026.
Abstract Since the early 1990s, the Ecological Society of America's journals have published hundreds of articles of direct relevance to those who teach ecology—especially at the undergraduate level. In an effort to draw attention to that literature, we conducted an analysis to identify well‐cited articles, as well as those that may be underrecognized ...

Triple positive solutions of BVP for second order ODE with one dimensional Laplacian on the half line

Electronic Journal of Qualitative Theory of Differential Equations, 2012
By applying Leggett-Williams fixed point theorem in a suitably constructed cone, we obtain the existence of at least three bounded positive solutions for a boundary value problem on the half line.

(How) Can Performance Appraisals Improve Employee Creativity? A Multidimensional Perspective

Human Resource Management, Volume 65, Issue 4, Page 1181-1197, July/August 2026.
ABSTRACT Performance appraisal (PA) is commonly used by organizations to manage their employees. However, the role of PAs in employee creativity remains ambiguous, with positive, negative, or even nonsignificant relationships reported in the literature. The aim of the present research is to address this ambiguity.

Balint Groups: A Catalytic Collaboration Between General Practice and Psychoanalysis

International Journal of Applied Psychoanalytic Studies, Volume 23, Issue 2, June 2026.
ABSTRACT This paper explores the foundations of Balint groups, a method for studying clinical relationships and countertransference. Enid and Michael Balint began holding seminars with general practitioners at the Tavistock Clinic in 1950, aiming to apply psychoanalytic principles to understand the doctor‐patient relationship.

Multiple periodic solutions for impulsive functional differential equations with feedback control

Electronic Journal of Differential Equations, 2011
Using the well known Leggett-Williams fixed point theorem, we study the existence of periodic solutions for a class of impulsive functional equations with feedback control. The main results are illustrated with two examples.

Existence of 2m-1 Positive Solutions for Sturm-Liouville Boundary Value Problems with Linear Functional Boundary Conditions on the Half-Line

Journal of Applied Mathematics, 2012
By using the Leggett-Williams fixed theorem, we establish the existence of multiple positive solutions for second-order nonhomogeneous Sturm-Liouville boundary value problems with linear functional boundary conditions.
