Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Employee sustainability teams—groups collaborating continuously and voluntarily on sustainability initiatives—can serve as a bottom‐up driver for organizational change. Despite their potential, however, their role and contributions are underexplored. To fill this gap, our multi‐case study examines 59 projects by 13 teams across three companies

Reliability model and algorithm research on HVDC system and flexible HVDC system
The Journal of Engineering, 2019 The main difference between flexible high-voltage direct current (HVDC) system and the traditional HVDC system is that there are two control degrees of freedom in the flexible HVDC system that is the amplitude and phase angle of the output voltage. While,

The Commutation Booster, a New Concept to Aid Commutation in Hybrid DC-Breakers [PDF]
, 2020 SUMMARY The difficulty in interrupting DC currents lies in the lack of a natural current zero crossing. In an ACbreaker, the current is interrupted by separating the contacts to draw an electric arc.

International Journal of Eating Disorders, EarlyView.ABSTRACT Objective Loss of control (LOC) eating in children is prospectively associated with excessive weight gain and elevated psychopathology. Parental LOC eating and negative mood in children have been linked to child LOC eating; however, objective evidence on parent–child concordance in energy intake and sense of LOC over eating, particularly in ...
