Cardiac arrest represents a dramatic event that can occur suddenly and often without premonitory signs, characterized by sudden loss of consciousness and breathing after cardiac output ceases and both coronary and cerebral blood flows stop. Restarting of the blood flow by cardiopulmonary resuscitation potentially re-establishes some cardiac output and organ blood flows. This article summarizes ...

The Social Construction of Disaster Disaster is widely perceived as an event beyond human control. The capricious hand of fate has moved against unsuspecting human communities, creating massive destruction and despair.[i] The sudden randomness of the event accentuates the cruelty of its effects, as surely the victims would have acted differently, had they known the risk. Other nations and organ...

Unexpected sudden (un)loading of the trunk may induce inadequate responses of trunk muscles and uncontrolled trunk motion. These unexpected perturbations may occur in pushing tasks, when the cart suddenly starts moving (unloading) or is blocked by an obstacle (loading). In pushing, handle height affects the user's working posture, which may influence trunk muscle activity and trunk movement in ...

The paper discusses frameworks in which the financial sector is at the eye of the storm. In that context, policies that do not repair the damage in the financial sector are, by necessity, second‐best. Actually, aggregate demand policies – emphasized in textbook Keynesian models – may be inferior to heterodox policies that rely on credit targeting. Moreover, based on salient characteristics of m...

Adaptive behavior requires the ability to flexibly control actions. This can occur either proactively to anticipate task requirements, or reactively in response to sudden changes. Here we report neuronal activity in the supplementary motor area (SMA) that is correlated with both forms of behavioral control. Single-unit and multiunit activity and intracranial local field potentials (LFPs) were r...
