Is Job Embeddedness a Resource? Revisiting the Relationship of Job Embeddedness and Employee Well‐Being: A Meta‐Analytic Investigation

Journal of Organizational Behavior, EarlyView.
ABSTRACT Job embeddedness (i.e., organizational and community factors that explain why employees remain in their organization) is generally regarded as a positive construct. However, a growing body of research suggests that embeddedness may also have detrimental effects on well‐being, particularly when considering nonwork and cross‐domain outcomes.

Different Levels, Same Relations? A Meta‐Analysis on the Homology of the Nomological Network of (Daily) Work Engagement

Journal of Organizational Behavior, EarlyView.
ABSTRACT Work engagement has garnered significant attention from researchers and practitioners in recent decades, and several meta‐analyses have examined its stable, between‐person correlates. However, work engagement also has a dynamic component, meaning that it varies daily, across situations, and within individuals.

Rapid identification method of commutation failure risk areas in HC-HVDC systems under single-phase faults

International Journal of Electrical Power & Energy Systems
The hybrid cascaded high voltage direct current (HC-HVDC) systems combine MMC and LCC features. However, single-phase ground faults on the AC lines of the receiving end power grid can easily cause LCC commutation failure on the inverter side.

Study on the Influence of Inconsistent Valve Parameters on LCC-HVDC Commutation and Operation

IEEE Access, 2019
Line commutated converter high voltage direct current (LCC-HVDC) transmission has unique advantages and plays an irreplaceable role in the power system. It is of great significance to study the commutation process.

Understanding the Concept of Self‐Performed Ultrasound: A Scoping Review

Journal of Ultrasound in Medicine, EarlyView.
Self‐performed ultrasound is an emerging technology that facilitates adept self‐scans in untrained hands. Inspired by self‐performed imaging in space for more prompt diagnosis and therapy, it has the potential to accurately monitor chronic conditions remotely. However, the lack of supervision and physical restraints can hinder its usability.

Effects of NDURE on Timely Adjuvant Radiotherapy in HNSCC: Subgroup Analysis of an RCT

The Laryngoscope, EarlyView.
In this subgroup analysis of a randomized clinical trial of 145 patients with locally advanced head and neck squamous cell carcinoma, the enhanced navigation‐based intervention NDURE improved initiation of timely postoperative radiation therapy (PORT) relative to usual care across nearly all demographic and clinical subgroups, including patients with ...

Adaptive VDCOL control strategy for the recovery of the UHVDC SPC system

The Journal of Engineering, 2019
The separating pole connection (SPC) mode of ultra-high-voltage direct current (UHVDC) can significantly improve the power stability, but when the AC bus of one pole is failed and two receiving systems are near, it may cause subsequent commutation ...

Quantization of Polaritons Confined in Dielectric Structures

Laser &Photonics Reviews, EarlyView.
This study addresses the limitations of the Hopfield model of strong light‐matter coupling in the case of structured dieletrics. A method to derive quantum models in the polariton basis using Bogoliubov transformation and third quantization is introduced, demonstrating how to boost interaction strength and engineer nonlocal interactions for strongly ...

Development of a Novel Commutation Method which Drastically Suppresses Commutation Failure of a Matrix Converter

IEEJ Transactions on Industry Applications, 2007
This paper proposes the safest novel commutation method for a matrix converter. There are two conventional commutation methods which depend on the polarity of the input line voltage (it is called “voltage commutation”) and depend on the polarity of the output current (it is called “current commutation”).
