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.

Bypassing SM strategy applied in interconnected LCC-HVDCs for commutation failure mitigation

, 2017
Recently, DC current reduction control for commutation failure mitigation is executed through point-to-point LCC-HVDC's rectifier. For an interconnected LCC-HVDC system through MMC-based DC-DC converter (MDC), MDC can be used to reduce the DC current ...

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.

CSR disclosure and investment efficiency in MENA countries: The moderating role of CSR committee

Strategic Change, EarlyView.
ABSTRACT Corporate social responsibility disclosure (CSRD) is often recognized as a transparency mechanism that allows companies to communicate their commitment to CSR. However, CSRD may also exacerbate agency conflicts. This study addresses these two contrasting perspectives by investigating the impact of CSRD on investment efficiency and exploring ...

Coordinated Control for Operating Characteristics Improvement of UHVDC Transmission Systems under Hierarchical Connection Scheme with STATCOM

Energies, 2019
Ultra-high voltage direct current (UHVDC) systems under hierarchical connection schemes (HCSs) linked to AC grids with different voltage levels (500 and 1000 kV) have been a great concern for power utilities to transfer bulk power.

Oppression‐based stressors, posttraumatic stress symptoms, and self‐injurious thoughts and behaviors among a national sample of queer adolescents of color

Journal of Traumatic Stress, EarlyView.
Abstract Oppression‐based stressors (OBS; e.g., heterosexism‐based stressors) are associated with a higher risk of trauma‐related symptoms and self‐injurious thoughts and behaviors (SITB) for queer (e.g., lesbian, gay, bisexual) adolescents. However, prior research has yet to examine posttraumatic stress symptoms (PTSS) and SITB in the context of the ...

Theory of Supercritical Coupling and Generalized Bound States in the Continuum

Laser &Photonics Reviews, EarlyView.
We develop a general theory of supercritical coupling and generalized bound states in the continuum (gBICs), revealing how interference between radiative and absorptive channels enables quality factors beyond conventional material‐loss limits. The framework unifies non‐Hermitian mode coupling, causality‐driven reactive interactions, and interference ...
