Quantitative trait locus (QTL) mapping is used to discover the genetic and molecular architecture underlying complex quantitative traits. It has important applications in agricultural, evolutionary, and biomedical research. R/qtl is an extensible, interactive environment for QTL mapping in experimental crosses. It is implemented as a package for the widely used open source statistical software R and contains a diverse array of QTL mapping methods, diagnostic tools for ensuring high-quality data, and facilities for the fit and exploration of multiple-QTL models, including QTL x QTL and QTL x environment interactions. This book is a comprehensive guide to the practice of QTL mapping and the use of R/qtl, including study design, data import and simulation, data diagnostics, interval mapping and generalizations, two-dimensional genome scans, and the consideration of complex multiple-QTL models. Two moderately challenging case studies illustrate QTL analysis in its entirety.

The book alternates between QTL mapping theory and examples illustrating the use of R/qtl. Novice readers will find detailed explanations of the important statistical concepts and, through the extensive software illustrations, will be able to apply these concepts in their own research. Experienced readers will find details on the underlying algorithms and the implementation of extensions to R/qtl. There are 150 figures, including 90 in full color.

Employing both large-scale surveys and in-depth interviews, the authors document the mental health effects on workers caused by the closure of four General Motor plants. They paint a portrait of how the social context in which these workers lived played a critical role in their experiences of unemployment or of keeping their jobs when others around them lost theirs. More than simply a study of unemployment and mental health, this book is also a story of coping and resilience.

This volume is based on a conference held to examine what is known about cognitive behaviors and brain structure and function in three syndromes and to evaluate the usefulness of such models. The goal of this endeavor is to add to the knowledge base of cognitive neuroscience within a developmental framework. Most of what is known about the neurological basis of cognitive function in humans has been learned from studies of central nervous system trauma or disease in adults. Certain neurodevelopmental disorders affect the central nervous system in unique ways by producing specific as opposed to generalized cognitive deficit. Studies of these disorders using neurobiological and behavioral techniques can yield new insights into the localization of cognitive function and the developmental course of atypical cognitive profiles.
The focus of this book is a discussion of the multidisciplinary research findings from studies of autism, and Williams and Turner syndromes. The approaches, methods, techniques, and findings reported are at the cutting edge of neuroscience research on complex behavior patterns and their neural substrates. Each disorder is accompanied by some degree of general cognitive impairment or mental retardation. Of greater interest are the atypical deficits in which a cognitive function is spared, such as language in Williams syndrome, or is disproportionately depressed as are spatial discrimination skills and visual-motor coordination in Turner syndrome. Drastically reduced or seemingly absent language capabilities and little interaction with other people characterize the core autism syndrome. A comprehensive and critical discussion of appropriate statistical techniques is made vivid by examples given from studies of small groups or single subjects in neurolinguistics and related fields.

The first volume begins with the early experiments into wireless telegraphy by Ernest Rutherford and ends with the New Zealand Broadcasting Service in the 1950s, just before the advent of television. Topics dealt with are the development and geographical spread of transmission and reception facilities, the political debates about broadcasting and consequential institutional changes, the interventionist role of the state in broadcasting, programming style and content, and the social and cultural consequences of broadcasting.

The hippocampus and parietal cortex have been implicated in various core spatial behaviors, such as the ability to localise and navigate to an object. Damage to these areas in animals and humans impairs these spatial functions. This collection of papers, written by internationally recognized experts in the field, reviews the evidence that each area is involved in spatial cognition, examines the mechanisms underlying the generation of spatial behaviors, and considers the relative roles of the hippocampal and parietal areas, including how each interacts with the other. The papers integrate a wide range of theoretical and experimental approaches, and touch on broader issues related to memory and imagery. As such, this book offers the most up-to-date research on the neural basis of spatial cognition. It should be of interest to anyone working in the fields of cognitive science, neuroanatomy, neuropsychology, and general cognition.

By examining German university medicine between 1750 and 1820, this book presents a new interpretation of the emergence of modern medical science. It demonstrates that the development of modern medicine as a profession linking theory and practice did not emerge suddenly from the revolutionary transformation of Europe at the opening of the nineteenth century, as Foucault and others have argued. Instead, Thomas H. Broman points to cultural and institutional changes occurring during the second half of the eighteenth century that reshaped both medical theory and physicians' professional identity. Among the most important of these factors was the emergence of a literary public sphere in Germany between 1750 and 1800, a development that exposed medical writing to new discourses such as Jena Romanticism and created the stage on which the bitter medical controversies of the 1790s would be played.
