THE INTENSIVE ELECTRIC SHOCK THERAPY OF CHRONIC DISTURBED PSYCHOTIC PATIENTS [PDF]
American Journal of Psychiatry, 1950 1. Intensive electric shock treatment was tried on a large, chronic, disturbed psychotic women's ward over a 3-month period. 2. As a result restraint was reduced roughly 90%, seclusion roughly 66%, and sedation roughly 90%. Patients in general became better "ward citizens."

Large-scale wind disturbances promote tree diversity in a Central Amazon forest. [PDF]
PLoS ONE, 2014 Canopy gaps created by wind-throw events, or blowdowns, create a complex mosaic of forest patches varying in disturbance intensity and recovery in the Central Amazon. Using field and remote sensing data, we investigated the short-term (four-year) effects
