In contrast to the assumption of efficiency wage models, which state that wage incentives should be positively correlated with productivity, high incentives may produce performance decrements in real life scenarios. Such a "choking under pressure" phenomenon exemplifies how psychological stress can profoundly shape human behavior, for good or for bad. Previous theories suggest that individual c...

BACKGROUND: Choking is common among psychiatric patients and represents one of the main causes of death in this patient population. PURPOSE: We aimed to identify common factors associated with choking among psychiatric patients. METHODS: The demographic information and medical history of 250 psychiatric patients living in an acute psychiatric ward were retrieved from medical charts, intervi...

This thesis examines the moderating effect of dispositional reinvestment upon ‘choking’ in cognitive based tasks such as decision-making. Study 1 tested sixty-three participants’ performances on lowand high-complexity tests of motor skill, psychomotor skill and working memory under lowand high-pressure conditions. The association between reinvestment and choking was shown to extend beyond the m...

We study viscous fingering instability in a soft Hele-Shaw cell, which one of the walls is replaced by bounded elastomer. For sufficiently high flow rates our experiments, fingers can get trapped because deforming solid contacts opposite wall, sealing cell near its rim, although numerical simulations axisymmetric bubble expansion at same control parameters, interface escapes. parameter regimes ...

An emergency condition is a situation that requires quick, precise, and appropriate action to save lives. Delays in providing assistance often occur children, where the result of this delay permanent disability even death. Emergency for children an important concern because are not used expressing uncomfortable conditions emergency. choking cardiac arrest. The purpose study was determine differ...

Flood flows in inundated urban environment constitute a natural hazard. During the 1213 January 2011 flood of the Brisbane River, detailed water elevation, velocity and suspended sediment data were recorded in an inundated street at the peak of the flood. The field observations highlighted a number of unusual flow interactions with the urban surroundings. These included some slow fluctuations i...
