TOPIC Concept analysis of risk. PURPOSE To analyze the concept risk and provide a new definition of risk. SOURCES Published literature. CONCLUSIONS A new definition of risk that emerged from this concept analysis can provide clarity and direction for future research. Nurse researchers can look to this definition to expand what is known about health-seeking behaviors as opposed to "risk" b...

The use of whole-brain imaging has shed new light on the organization of the dopamine system.

Most theories of psychotic-like experiences posit the involvement of cognitive mechanisms. The current research examined the relations between psychotic-like experiences and two cognitive mechanisms, high aberrant salience and low self-concept clarity. In particular, we examined whether aberrant salience, or the incorrect assignment of importance to neutral stimuli, and low self-concept clarity...

Measures of chromatic contrast sensitivity in children are lower than those of adults. This may be related to immaturities in signal processing at or near threshold. We have found that children's VEPs in response to low contrast supra-threshold chromatic stimuli are more intra-individually variable than those recorded from adults. Here, we report on linear and nonlinear analyses of chromatic VE...

The assessment of aggression against women is demanding primarily because assessment strategies do not share a common language to describe reliably the wide range of forms of aggression women experience. The lack of a common language impairs efforts to describe these experiences, understand causes and consequences of aggression against women, and develop effective intervention and prevention ef...

Information consumers seek to learn about world events, but often also what others know about those events. Capturing consumers’ attention is essential for information suppliers to thrive in the market. We find that competition for attention leads to homogeneity of information sources—in terms of accuracy and clarity—even when consumers would demand heterogeneous sources. Their equilibrium type...
