Gendered Pathways to Work–Family Balance and Their Consequences: Insights From Dual‐Career Faculty Couples

Human Resource Development Quarterly, EarlyView.
ABSTRACT This study examines gendered work–family balance (WFB) experiences among dual‐career academic couples at U.S. research‐intensive universities. By comparing faculty couples who shared the same or similar professional and family contexts, the study explores how gendered demands, challenges, resources, and strategies shaped distinct WFB outcomes.

Enforced but not Enacted: How Return‐to‐Office Policies Reshape Boundary Enactment, Work‐Location Volition, and Eudaimonic Wellbeing

Human Resource Management, EarlyView.
ABSTRACT HR faces a conundrum over how to organize hybrid working patterns given the pros and cons associated with conducting work across multiple domains. Many organizations are currently seeking to clarify and often increase the requirements for employee presence at employer premises, meaning studies are needed to better understand how HR should look

Managing Virtual Work: An Integrative Framework for Human Resource Management

Human Resource Management, EarlyView.
ABSTRACT Virtual work has become a defining feature of contemporary organizations, yet Human Resource Management (HRM) scholarship lacks an integrated understanding of how it should be managed. We address this disconnect by shifting the focus from individual and team experiences to the organizational management of virtual work through HRM.

Deniers and Compliers: Unpacking the Heterogeneous Effectiveness of U.S. Stay‐at‐Home Mandates During the COVID‐19 Pandemic

Journal of Applied Econometrics, EarlyView.
ABSTRACT While existing work shows COVID‐19 stay‐at‐home (SAH) policies decreased mobility on average, we lack evidence regarding heterogeneity in policy effectiveness across US counties. To uncover potential heterogeneity, we implement a novel two‐stage approach.

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.
