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.

Characteristics of commutation failure based on fault recording
, 2018 Commutation failure of the high-voltage direct current (HVDC) transmission system is common fault in a converter station. The fault recording in one converter station when commutation failure caused by the disturbance of the AC system was collected, and ...

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.

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.

Markov‐Associated Quadratic Stochastic Families and the Susceptible‐Infected‐Recovered (SIR) Model
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT We introduce a Markov‐associated construction for quadratic stochastic families generated by a symmetric cubic stochastic matrix and a finite‐state homogeneous Markov semigroup. The constructed family is not assumed to be a classical quadratic stochastic process of type (A)$$ (A) $$ or type (B)$$ (B) $$; rather, it is a Markov‐associated ...
