Validation of a Short Stress State Questionnaire
Stress is an important aspect of operational settings. This article presents two studies providing initial psychometric and validation evidence of a short multidimensional self-report measure of…
An analytical review of vasculobiliary injury in laparoscopic and open cholecystectomy.
TLDR
Routine arteriography is recommended in patients with a biliary injury if early repair is contemplated and consideration should be given to delaying repair of a bile duct injury in Patients with occlusion of the RHA.

TLDR
Overall the results indicate that the SART is sensitive to impulsive responding.
Signal regularity and the mindlessness model of vigilance.
TLDR
The present study challenges the validity of the mindlessness model by showing that with both types of task, observers utilize subtle patterns in the temporal structure of critical signal appearances to develop expectations about the time course of those appearances that affect performance efficiency.
Working memory load and the vigilance decrement
TLDR
Results support the view that the vigilance decrement results from high cognitive resource demands, not from cognitive under-load (e.g., boredom or mindlessness), and suggest utilization of common executive resources.
Pretreatment assessment of hepatocellular carcinoma: expert consensus statement.
TLDR
Assessment of tumor response should not rely only on tumor size and new imaging methods are available to evaluate response to therapy in HCC patients, and dual phase computed tomography or magnetic resonance imaging can be used for pretreatment assessment of tumor extent.
The abbreviated vigilance task and cerebral hemodynamics
TLDR
There was a significant decline in performance over time, but there was no significant change in the physiological measures over time during the abbreviated vigil, which does not match the physiological changes detected in long-duration vigils.
Effects of warned and unwarned demand transitions on vigilance performance and stress
TLDR
A dynamic model of performance stress may be necessary and research employing vigilance tasks in the future may be useful for developing this performance-stress model.
