Book Description
Variation in Time and Space: Observing the World through Corpora is a collection of articles that address the theme of linguistic variation in English in its broadest sense. Current research in English language presented in the book explores a fascinating number of topics, whose unifying element is the corpus linguistic methodology. Part I of this volume, Meaning in Time and Space, introduces the two dimensions of variation – time and space – relating them to the negotiation of meaning in discourse and questions of intertextuality. Part II, Variation in Time, approaches the English language from a diachronic point of view; the time periods covered vary considerably, ranging from 16th century up to present-day; so do the genres explored. Part III, Variation in Space, focuses on global varieties of English and includes a contrastive point of view. The range of topics is again broad – from specific lexico-grammatical structures to the variation in academic English, combining the regional and genre dimensions of variation. This is a timely volume that shows the breadth and depth in current corpus-based research of English.

Book Description
Darwin's theory of evolution by natural selection was based on the observation that there is variation between individuals within the same species. This fundamental observation is a central concept in evolutionary biology. However, variation is only rarely treated directly. It has remained peripheral to the study of mechanisms of evolutionary change. The explosion of knowledge in genetics, developmental biology, and the ongoing synthesis of evolutionary and developmental biology has made it possible for us to study the factors that limit, enhance, or structure variation at the level of an animals' physical appearance and behavior. Knowledge of the significance of variability is crucial to this emerging synthesis. Variation situates the role of variability within this broad framework, bringing variation back to the center of the evolutionary stage. - Provides an overview of current thinking on variation in evolutionary biology, functional morphology, and evolutionary developmental biology - Written by a team of leading scholars specializing on the study of variation - Reviews of statistical analysis of variation by leading authorities - Key chapters focus on the role of the study of phenotypic variation for evolutionary, developmental, and post-genomic biology

Book Description
This volume offers several empirical, methodological, and theoretical approaches to the study of observable variation within individuals on various linguistic levels. With a focus on German varieties, the chapters provide answers on the following questions (inter alia): Which linguistic and extra-linguistic factors explain intra-individual variation? Is there observable intra-individual variation that cannot be explained by linguistic and extra-linguistic factors? Can group-level results be generalised to individual language usage and vice versa? Is intra-individual variation indicative of actual patterns of language change? How can intra-individual variation be examined in historical data? Consequently, the various theoretical, methodological and empirical approaches in this volume offer a better understanding of the meaning of intra-individual variation for patterns of language development, language variation and change. The inter- and transdisciplinary nature of the volume is an exciting new frontier, and the results of the studies in this book provide a wealth of new findings as well as challenges to some of the existing findings and assumptions regarding the nature of intra-individual variation.
