Rats' acquisition of the ephemeral reward task.

The ephemeral reward task provides a subject with a choice between two alternatives A and B. If it chooses alternative A, reinforcement follows and the trial is over. If it chooses alternative B, reinforcement follows but the subject can also respond to alternative A which is followed by a second reinforcement.

Evaluation of Contingency Telemedical Support to Improve Casualty Care at a Simulated Military Intermediate Resuscitation Facility: The EM-ANGEL Study.

Objective: We sought to determine whether Contingency Telemedical Support (CTS) improves the success rate and efficiency of primary care providers performing critical actions during simulated combat trauma resuscitation. Critical actions included advanced airway, chest decompression, extremity hemorrhage control, hypothermia prevention, antibiotics and analgesics, and hypotensive resuscitation, among others.

Background: Recent studies report improved survival associated with skilled triage and treatment in the out-of-hospital/preoperative phase of combat casualty care.
