Using familiar concepts from classical measurement methods and basic statistics, Hambleton and colleagues introduce the basics of item response theory (IRT) and explain the application of IRT methods to problems in test construction, identification of potentially biased test items, test equating, and computerized-adaptive testing. The book also includes a thorough discussion of alternative proceduers for estimating IRT parameters, such as maximum likehood estimation, marginal maximum likehood estimation, and Bayesian estimation in such a way that the reader does not need a knowledge of calculus to follow these explanations.

The Hairy Ape - A Comedy of Ancient and Modern Life
The play tells the story of a brutish, unthinking laborer known as Yank, as he searches for a sense of belonging in a world controlled by the rich. O'Neill himself acknowledged that The Hairy Ape straddles a number of styles. "It seems to run the gamut from extreme naturalism to extreme expressionism—with more of the latter than the former," he wrote in 1921. The initial response to productions of The Hairy Ape focused on the skill of the play's staging and its forceful impact on a viewer.
It was bad enough that Catherine Gagnon survived a horrible childhood abduction where for a month she lived in a cave and was the plaything for her sicko abductor. But now, 25 years later, she faces tragedy again as she fights to keep her son, Nathan. One chilly November night, a police sniper kills her husband, Jimmy, in response to her 911 call claiming he was about to hurt Nathan. Jimmy's death means that his parents, an influential judge and his blue-blooded wife, are more determined than ever to take Nathan from Catherine, whom they see as unfit to mother their only grandchild.
