Spotlighting two of the most prevalent and most researched genetically based disabilities - Down syndrome and Fragile X syndrome - this cutting-edge text clarifies the distinct speech and language issues associated with each disorder and helps readers conduct individualized assessment and intervention.An essential upper-level textbook and an invaluable professional reference, this book gives readers the up-to-date research and clinical insight they need to: fully understand both disabilities - the behaviors, characteristics, genetics, and treatments associated with each; see how speech and language develop across the lifespan, from infancy to adulthood; apply principles of effective assessment with people from every age group; use specific interventions to support key aspects of speech and language development; tailor assessment and intervention to an individual's communicative needs and abilities; tune into the family's perspective and encourage their ongoing involvement; and examine other disorders by using this research as a model for future practice.Authoritative contributions from more than 15 leading experts prepare readers for effective clinical practice, and the ""directions for research"" sections throughout the book help researchers shape future studies and move the field forward. A necessary resource for SLPs, pediatricians, AAC specialists, and early interventionists, this definitive volume is key to supporting the communicative competence of people with Down syndrome and Fragile X syndrome at every stage of life.

With the poems written by winner of the Posner Poetry Award from the Council of Wisconsin Writers in 2005, this coffee-table book will delight and inform general readers curious about ideas of chaos, fractals, and nonlinear complex systems. Developed out of ten years of interdisciplinary seminars in chaos and complex systems at the University of Wisconsin-Madison, it features multiple ways of knowing: Robin Chapman's poems of everyday experience of change in a complex world, associated metaphorically with Julien Clinton Sprott's full-color computer art generated from billions of versions of only three simple equations for strange attractors, Julia sets, and iterated function systems; his definitions of 39 key terms; a mathematical appendix; and even a multiple-choice quiz to test understanding. Accompanied by a CD-ROM of the poet reading 13 poems and 1,000 images of chaos art from which slide shows can be generated and 100 high-resolution posters created, the book has a foreword by Cliff Pickover, author of A Passion for Mathematics.
