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.

(How) Can Performance Appraisals Improve Employee Creativity? A Multidimensional Perspective
Human Resource Management, EarlyView.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.
