First published in 1994, this crosslinguistic collection looks at changes and developments in language involving gain or loss in structural complexity or utility. The dynamics of these processes of progression and regression are examined at the societal and the individual level, and the two are compared. In the former, the focus is on the social and cultural forces that influence groups of speakers to create new languages or abandon old ones. In the latter, the acquisition and attrition of both first and second languages are considered. Questions raised include: Can parallel structural patterning be observed in whole languages and in the individual's version of a language? Is there parallelism between progression and regression? Can changes occurring in progression and regression be interpreted in a typological framework? These are addressed from sociological, neuropsychological, and linguistic perspectives.

Draws together a wide range of elements relating to craniofacial analysis and identification, examining the latest advances in the field.

This successful book, now available in paperback, provides academics and researchers with a clear set of prescriptions for estimating, testing and probing interactions in regression models. Including the latest research in the area, such as Fuller's work on the corrected/constrained estimator, the book is appropriate for anyone who uses multiple regression to estimate models, or for those enrolled in courses on multivariate statistics.

The Cobb-Douglas regression, a statistical technique developed to estimate what economists called a 'production function', was introduced in the late 1920s. For several years, only economist Paul Douglas and a few collaborators used the technique, while vigorously defending it against numerous critics. By the 1950s, however, several economists beyond Douglas's circle were using the technique, and by the 1970s, Douglas's regression, and more sophisticated procedures inspired by it, had become standard parts of the empirical economist's toolkit. This volume is the story of the Cobb-Douglas regression from its introduction to its acceptance as general-purpose research tool. The story intersects with the histories of several important empirical research programs in twentieth century economics, and vividly portrays the challenges of empirical economic research during that era. Fundamentally, this work represents a case study of how a controversial, innovative research tool comes to be widely accepted by a community of scholars.

Developed by the National Academy of Sports Medicine (NASM), this book is designed to help people prepare for the NASM Certified Personal Trainer (CPT) Certification exam or learn the basic principles of personal training using NASM's Optimum Performance Training (OPT) model. The OPT model presents NASM's protocols for building stabilization, strength, and power. More than 600 full-color illustrations and photographs demonstrate concepts and techniques. Exercise color coding maps each exercise movement to a specific phase on the OPT model. Exercise boxes demonstrate core exercises and detail the necessary preparation and movement. Other features include research notes, memory joggers, safety tips, and review questions.
