Trends in hospitalizations for vaccine‐preventable diseases in the United States from 2014 to 2024

open access: yesJournal of Hospital Medicine, EarlyView.
Abstract Background and Objectives Vaccination rates have declined in recent years, resulting in outbreaks of vaccine‐preventable diseases (VPDs) among children. We aimed to evaluate VPD hospitalization rates from 2014 to 2024 and to report associated trends in outcomes including intensive care utilization, mortality, readmissions, and costs.

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

open access: yesJournal 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.

Commutation Groups and State-Independent Contextuality [PDF]

open access: yes
We introduce an algebraic structure for studying state-independent contextuality arguments, a key form of quantum non-classicality exemplified by the well-known Peres-Mermin magic square, and used as a source of quantum advantage.

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

open access: yesJournal 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.
