Measuring Organizational Resilience in a Resource‐Constrained Environment: An Empirical Study of Micro‐and‐Small‐Service‐Enterprises (MSSEs) in Nigeria

open access: yesStrategic Change, EarlyView.
ABSTRACT There is growing evidence that a preponderance of resilience indicators discussed in management scholarship is often developed with limited consideration of the context in which micro‐and‐small‐service enterprises (MSSEs) operate. Given their strategic relevance to developing economies, it thus becomes necessary to understand the meaning of ...

The Computational Solution of Generalized Inverse Eigenvalue Problem for Pseudo-Jacobi Matrix

open access: yesJournal of Mathematics
This paper is concerned with two generalized inverse eigenvalue problems for a kind of pseudo-Jacobi matrix. From a non-Hermite matrix, an r×r Jacobi matrix, two distinct real eigenvalues, and part of the corresponding eigenvectors, an n×n pseudo-Jacobi ...

Psychometric considerations of Adverse Childhood Experiences Questionnaire: Structure, validity, and the development of a supplementary instrument

open access: yesJournal of Traumatic Stress, EarlyView.
Abstract Adverse childhood experiences (ACEs) are linked to numerous negative physical and mental health outcomes. The current study addressed theoretical, conceptual, and measurement problems by evaluating a novel extension to the seminal ACEs questionnaire (ACEs‐Q).

Generalized second order vectorial ∞-eigenvalue problems

open access: yesProceedings of the Royal Society of Edinburgh: Section A Mathematics
We consider the problem of minimizing the $L^\infty$ norm of a function of the hessian over a class of maps, subject to a mass constraint involving the $L^\infty$ norm of a function of the gradient and the map itself.

Phenotypic Subtypes of Obstructive Eustachian Tube Dysfunction as Defined by Cluster Analysis

open access: yesThe Laryngoscope, EarlyView.
Obstructive ETD encompasses five clinically distinct phenotypes, ranging from mild, post‐upper respiratory infection presentations to chronic, bilateral disease driven by sinusitis and reflux. These were identified through hierarchical cluster analysis of 490 patients using seven key clinical variables.

Aquatic and Littoral Successions in Various Post‐Mining Sites—Patterns and Possible Use in Ecological Restoration

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Vegetation succession in aquatic and littoral habitats has received much less attention than terrestrial habitats have. We sampled differently aged successional stages at five different types of post‐mining sites, that is, sandpits, stone quarries, clay quarries, brown coal spoil heaps and black coal subsidences, across the Czech Republic ...

Inverse Design of Mirror‐Symmetric Disordered Systems for Broadband Perfect Transmission

open access: yesLaser &Photonics Reviews, EarlyView.
This work introduces an inverse design approach to achieve broadband perfect wave transmission in mirror‐symmetric disordered media. Leveraging symmetry simplifies optimization and enables control of multiple reflectionless states. Experiments in microwave waveguides confirm the design of exceptional points, bandpass filters, and broadband quasi ...

Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies

open access: yesLaser &Photonics Reviews, EarlyView.
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.
