Positive Solutions to Periodic Boundary Value Problems of Nonlinear Fractional Differential Equations at Resonance

International Journal of Differential Equations, 2016
By Leggett-Williams norm-type theorem for coincidences due to O’Regan and Zima, we discuss the existence of positive solutions to fractional order with periodic boundary conditions at resonance.

Questioning Your Brilliance in Physics: Differential Shifts in Fixed Mindsets by Grade and Gender

Journal of Research in Science Teaching, EarlyView.
ABSTRACT Students' domain‐specific mindsets and their beliefs about their capacity to improve through effort play a crucial role in shaping their experiences and decisions to persist in STEM disciplines. Physics is generally seen as a field requiring innate brilliance, which can reinforce fixed mindsets, particularly after initial setbacks in ...

Theorising the Impacts of Polycrisis on Employment Relations: Complexity and Diversity at a Global Scale

British Journal of Industrial Relations, EarlyView.
ABSTRACT Polycrisis—understood as intersecting crises that amplify each other rather than unfolding separately—poses profound challenges for employment relations theory and practice. The employment relationship is simultaneously a site where the effects of crises are most acutely experienced and a central mechanism through which profit is generated ...

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.

Eco‐Evo‐Hydraulics: Integrating Fish Evolution Into Ecohydraulics for Conservation

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Riverine fish conservation in eco‐hydraulics is often based on restoring or regulating river habitat to a semi‐natural state. For example, ecohydraulic projects support fish populations by increasing river connectivity through fishways, and by maintaining or restoring natural flow variance to enhance habitat quality and availability.

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.

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.

Changing perspectives: The development of preservice teachers' field‐specific ability beliefs across academic disciplines

British Journal of Educational Psychology, Volume 96, Issue 1, Page 337-355, March 2026.
Abstract Background Field‐specific ability beliefs (FABs) reflect the perception that success in academic fields depends on innate, unteachable abilities. These beliefs affect teaching practices and student motivation. However, little is known about their longitudinal development during teacher education. Aims This study examines how FABs evolve during

Three symmetric positive solutions of fourth-order singular nonlocal boundary value problems

Electronic Journal of Qualitative Theory of Differential Equations, 2011
In this paper, we study the existence of three positive solutions of fourth-order singular nonlocal boundary value problems. We show that there exist triple symmetric positive solutions by using Leggett-Williams fixed-point theorem.

How coworker proactive behavior drives employee bootlegging: The roles of goal orientation and self‐construal

Applied Psychology, Volume 75, Issue 1, February 2026.
Abstract Unauthorized, proactive innovative behavior (i.e., bootlegging) is increasingly recognized as an important driver of innovation. Although existing research has predominantly focused on explaining the emergence of bootlegging through formal influences (e.g., leadership and organizational practices), less attention has been paid to the impact of
