This article presents the results of studying two different forms of probing about volunteering.

The other is an experimental approach that uses behavioral prompts in which respondents are asked if they did certain things or performed ...

A skew in the base rate of upcoming events can often provide a better cue for accurate predictions than a contingency between signals and events. The authors study prediction behavior and test people's sensitivity to both base rate and contingency; they also examine people's ability to compare the benefits of both for prediction. They formalize these ...

The moderator temperature coefficient (MTC) is an important parameter in the transient behavior of pressurized water reactors (PWRs).
