Emergency department(ED) nurses work in a rapidly changing environment with patients that have wide variety of conditions. Occupational stress in emergency department nurses is a common problem. The purpose of this study was to describe the relationship between coping strategies and occupational stress among ED nurses in China. A correlational,(More)
In reward-based learning, synaptic modifications depend on a brief stimulus and a temporally delayed reward, which poses the question of how synaptic activity patterns associate with a delayed reward. A theoretical solution to this so-called distal reward problem has been the notion of activity-generated "synaptic eligibility traces," silent and transient(More)
A general theory views the function of all neurons as prediction, and one component of this theory is that of "predictive homeostasis" or "prediction error." It is well established that sensory systems adapt so that neuronal output maintains sensitivity to sensory input, in accord with information theory. Predictive homeostasis applies the same principle at(More)
The conventional interpretation of spikes is from the perspective of an external observer with knowledge of a neuron's inputs and outputs who is ignorant of the contents of the "black box" that is the neuron. Here we consider a neuron to be an observer and we interpret spikes from the neuron's perspective. We propose both a descriptive hypothesis based on(More)
Although neurons within intact nervous systems can be classified as 'sensory' or 'motor,' it is not known whether there is any general distinction between sensory and motor neurons at the cellular or molecular levels. Here, we extend and test a theory according to which activation of certain subtypes of voltage-gated ion channel (VGC) generate patterns of(More)
AIMS To investigate the impact of nurses' perception of patient safety culture and adverse event reporting, and demographic factors on adverse event reporting in Chinese hospitals. BACKGROUND Accurate and timely adverse event reporting is integral in promoting patient safety and professional learning around the incident. METHODS In a cross-sectional(More)
