Journal of Management Studies, Volume 59, Issue 8, Page 2024-2066, December 2022., 2022 Abstract How and when does engagement with a stigmatized organization lead to the transfer of its stigma to organizations and individuals associating with it? To answer this question, we conduct an inductive study of the process of stigma transfer and the conditions determining social actors’ susceptibility to such courtesy stigma. We build our process

On the demand for telemedicine: Evidence from the COVID‐19 pandemic
Health Economics, Volume 31, Issue 7, Page 1491-1505, July 2022., 2022 Abstract Telemedicine can expand access to health care at relatively low cost. Historically, however, demand for telemedicine has remained low. Using administrative records and a difference‐in‐differences methodology, we estimate the change in demand for telemedicine experienced after the onset of the COVID‐19 epidemic and the imposition of mobility ...

Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022 We are concerned with the following nonlocal problem involving critical Sobolev exponent −a−b∫Ω∇u2dxΔu=λuq−2u+δu2u,x∈Ω,u=0,x∈∂Ω, where Ω is a smooth bounded domain in ℝ4, a, b > 0, 1 < q < 2, δ, and λ are positive parameters. We prove the existence of two positive solutions and obtain uniform estimates of extremal values for the problem.

Parametric Ekeland's variational principle [PDF]
, 2001 A parametrized version of Ekeland's variational principle is proved, showing that under suitable conditions, the minimum point of the perturbed function can be chosen to depend continuously on a parameter.

Abstract and Applied Analysis, Volume 2022, Issue 1, 2022., 2022 In this paper, we establish a generalization of the Galewski‐Rădulescu nonsmooth global implicit function theorem to locally Lipschitz functions defined from infinite dimensional Banach spaces into Euclidean spaces. Moreover, we derive, under suitable conditions, a series of results on the existence, uniqueness, and possible continuity of global ...

A Generalization of Ekeland's ϵ-Variational Principle and Its Borwein–Preiss Smooth Variant [PDF]
, 2000 We give a generalization of Ekeland's ϵ-Variational Principle and of its Borwein–Preiss smooth variant, replacing the distance and the norm by a “gauge-type” lower semi-continuous function.

Local completeness, drop theorem and Ekeland's variational principle [PDF]
, 2005 By using a very general drop theorem in locally convex spaces we obtain some extended versions of Ekeland's variational principle, which only need assume local completeness of some related sets and improve Hamel's recent results.

Generalized Ekeland’s variational principle with applications
Journal of Inequalities and Applications, 2019 By using the concept of Γ-distance, we prove EVP (Ekeland’s variational principle) on quasi-F-metric (q-F-m) spaces. We apply EVP to get the existence of the solution to EP (equilibrium problem) in complete q-F-m spaces with Γ-distances.

On p‐Laplace Equations with Singular Nonlinearities and Critical Sobolev Exponent
Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022 In this paper, we deal with p‐Laplace equations with singular nonlinearities and critical Sobolev exponent. By using the Nehari manifold, Mountain Pass theorem, and Maximum principle theorem, we prove the existence of at least four distinct nontrivial solutions.
