Existence of Three Positive Solutions to Some p-Laplacian Boundary Value Problems
Discrete Dynamics in Nature and Society, 2013 We obtain, by using the Leggett-Williams fixed point theorem, sufficient conditions that ensure the existence of at least three positive solutions to some p-Laplacian boundary value problems on time scales.

A Leggett-Williams type theorem applied to a fourth order problem [PDF]
, 2012 We apply an extension of a Leggett-Williams type fixed point theorem to a two-point boundary value problem for a fourth order ordinary differential equation.

Positive Solutions for a Mixed-Order Three-Point Boundary Value Problem for p-Laplacian
Abstract and Applied Analysis, 2013 The author investigates the existence and multiplicity of positive solutions for boundary value problem of fractional differential equation with p-Laplacian operator. The main tool is fixed point index theory and Leggett-Williams fixed point theorem.

Review of Education, Volume 14, Issue 3, December 2026.Abstract Despite significant recent growth in the Science, Technology, Engineering and Mathematics (STEM) fields, disadvantaged groups continue to face systematic barriers in accessing STEM education opportunities. In response, a wide range of K–12 STEM interventions have emerged to address these inequities.

British Journal of Industrial Relations, Volume 64, Issue 3, Page 570-583, September 2026.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 ...

Questioning Your Brilliance in Physics: Differential Shifts in Fixed Mindsets by Grade and Gender
Journal of Research in Science Teaching, Volume 63, Issue 6, Page 514-530, August 2026.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 ...

Soil Seed Bank Holds Some Potential for Natural Regeneration in a Semi‐Arid Rangeland
Austral Ecology, Volume 51, Issue 8, August 2026.ABSTRACT Natural regeneration of degraded lands can be facilitated by the recruitment of plant species from the soil seed bank. However, the composition of soil seed banks in arid Australia has seldom been studied. We addressed this knowledge gap by quantifying the soil seed bank of chenopod shrubland and remnant Acacia aneura (mulga) stands in an ex ...
