Accessible to a range of readers, this book traces the developmental course of each disorder and shows how biological, psychological, and sociocultural factors interact with a child's environment. It illustrates how troubled children behave in their natural settings: homes, schools, and communities.

A thorough revision of a popular text in combinatorial game theory, this second edition reorganizes presentation to make it more widely accessible. The beginning focuses less on technical and more on conceptual material and applications. Still written in a textbook style with supporting evidence and proofs, the authors add many more exercises and examples and implement a two-step approach for some aspects of the material involving an initial introduction, examples, and basic results to be followed later by more technical and abstract results.

This second collection of interesting mathematical puzzles continues the tribute to Martin Gardner, who has provided us with original puzzles and puzzling stories ever since he created and produced the "Mathematical Games" column in Scientific American. The international community of puzzle enthusiasts has gathered once again to celebrate Martin Gardner's continued contribution and, most fittingly, has done so in kind, by providing new challenges to our inquiring minds. We proudly present this collection to the mathemagicians of the world for their enjoyment, as a playful provocation.
