Validation Questions Are Not Enough—Bots Can Mimic Human Responses and Voices to Infiltrate Your Study: Commentary on Pennesi et al. (2026)

International Journal of Eating Disorders, EarlyView.
ABSTRACT As online research has proliferated, so too have threats to data integrity. Recent literature continues to raise concerns with survey fraud and threats to data integrity in online eating disorder (ED) research. In this commentary, we expand on recent work by describing threats to data integrity we are currently encountering in our online ...

FAULT RIDE-THROUGH CAPABILITY AND DAMPING IMPROVEMENT IN DFIG

, 2016
Doubly-fed induction generator wind turbine is susceptible to faults and requires crowbar protection. When the crowbar is triggered, the rotor is short circuited over the crowbar impedance. Then, the doubly-fed induction generator operates as a squirrel-cage induction generator that tends to absorb large amount of reactive power from the grid during ...

How Fitness Center Environments Influence Eating Disorder Recovery: Learning From Women With Lived Experience

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Eating disorders (ED) are serious illnesses that compromise the physical and psychological health of those who suffer from them. With maladaptive exercise being a common ED symptom, individuals with EDs may gravitate to fitness centres where pro‐weight loss, anti‐fat messages are the norm.
