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
Fiction. NECROPHILIA VARIATIONS is a literary monograph on the erotic attraction to corpses and death. It consists of a series of texts that, like musical phrases, take up the theme and advance it by means of repetition, contrast, and variation.Written in a style that ranges from the lugubrious to the ludicrous--from purple prose to black humor--NECROPHILIA VARIATIONS uses literary means to probe the psychopathology of sexual perversion. Eros, the book asks, is naturally drawn to beauty, and yet nothing would seem to be less inherently beautiful than a cadaver. How is it that a necrophile ends up confusing the two, discovering beauty in what most people would find repugnant? How does he come to desire that which would seem to be intrinsically undesirable? If you have ever contemplated the curious points of contact between eros and thanatos, then Necrophilia Variations will be sure to delight you with its depictions of death, desire, and deviance.

Book Description
Recent developments in molecular and computational methods have made it possible to identify the genetic basis of any biological trait, and have led to spectacular advances in the study of human disease. This book provides an overview of the concepts and methods needed to understand the genetic basis of biological traits, including disease, in humans. Using examples of qualitative and quantitative phenotypes, Professor Weiss shows how genetic variation may be quantified, and how relationships between genotype and phenotype may be inferred. This book will appeal to many biologists and biological anthropologists interested in the genetic basis of biological traits, as well as to epidemiologists, biomedical scientists, human geneticists and molecular biologists.

Book Description
In today’s culturally diverse classrooms, students possess and use many culturally, ethnically, and regionally diverse English language varieties that may differ from standardized English. This book helps classroom teachers become attuned to these differences and offers practical strategies to support student achievement while fostering positive language attitudes in classrooms and beyond. The text contrasts standardized varieties of English with Southern, Appalachian, and African American English varieties, focusing on issues that are of everyday concern to those who are assessing the linguistic competence of students. Featuring a narrative style with teaching strategies and discussion questions, this practical resource: Provides a clear, introductory explanation of what is meant by non-standard English, from both linguistic and educational viewpoints. Emphasizes what educators needs to know about language variation in and outside of the classroom. Addresses the social factors accompanying English language variation and how those factors interact in real classrooms. “A landmark book. . . . It guides linguists and educators as we all work to apply our knowledge on behalf of those for whom it matters most: students.” —From the Afterword by Walt Wolfram, North Carolina State University “In the ongoing debate about language we typically hear arguments about what students say and/or how they say it. Finally, a volume that takes on the ‘elephant in the parlor’—WHO is saying it. By laying bare the complicated issues of race, culture, region, and ethnicity, Charity Hudley and Mallinson provide a scholarly significant and practically relevant text for scholars and practitioners alike. This is bound to be an important contribution to the literature.” —Gloria Ladson-Billings, University of Wisconsin–Madison “An invaluable guide for teachers, graduate students, and all lovers of language. The authors provide a comprehensive and fascinating account of Southern and African American English, showing how it differs from standardized English, how those differences affect children in the classroom, and how teachers can use these insights to better serve their students.” —Deborah Tannen, University Professor and professor of linguistics, Georgetown University

Book Description
The problem of finding minimal surfaces, i. e. of finding the surface of least area among those bounded by a given curve, was one of the first considered after the foundation of the calculus of variations, and is one which received a satis factory solution only in recent years. Called the problem of Plateau, after the blind physicist who did beautiful experiments with soap films and bubbles, it has resisted the efforts of many mathematicians for more than a century. It was only in the thirties that a solution was given to the problem of Plateau in 3-dimensional Euclidean space, with the papers of Douglas [DJ] and Rado [R T1, 2]. The methods of Douglas and Rado were developed and extended in 3-dimensions by several authors, but none of the results was shown to hold even for minimal hypersurfaces in higher dimension, let alone surfaces of higher dimension and codimension. It was not until thirty years later that the problem of Plateau was successfully attacked in its full generality, by several authors using measure-theoretic methods; in particular see De Giorgi [DG1, 2, 4, 5], Reifenberg [RE], Federer and Fleming [FF] and Almgren [AF1, 2]. Federer and Fleming defined a k-dimensional surface in IR" as a k-current, i. e. a continuous linear functional on k-forms. Their method is treated in full detail in the splendid book of Federer [FH 1].

Book Description
Variability arises in multistage manufacturing processes (MMPs) from a variety of sources. Variation reduction demands data fusion from product/process design, manufacturing process data, and quality measurement. Statistical process control (SPC), with a focus on quality data alone, only tells half of the story and is a passive method, taking corre

Book Description
This is an open access title available under the terms of a CC BY-NC-ND 4.0 International licence. It is free to read at Oxford Academic and offered as a free PDF download from OUP and selected open access locations. This book introduces a systematic framework for understanding and investigating lexical variation, using a distributional semantics approach. Distributional semantics embodies the idea that the context in which a word occurs reveals the meaning of that word. In contemporary corpus linguistics, that idea takes shape in various types of quantitative analysis of the corpus contexts in which words appear. In this book, the authors explore how count-based token-level semantic vector spaces, as an advanced form of such a quantitative methodology, can be applied to the study of polysemy, lexical variation, and lectometry. What can distributional models reveal about meaning? How can they be used to analyse the semantic relationship between near-synonyms, and to identify strict synonymy? How can they contribute to the study of lexical variation as a sociolinguistic variable, and to the use of those variables to measure convergence or divergence between language varieties? To answer these questions, the book presents a comprehensive model of lexical and semantic variation, based on the combination of a semasiological, an onomasiological, and a lectal dimension. It explains the mechanism of distributional modelling, both informally and technically, and introduces workflows and corpus linguistic tools that implement a distributional perspective in lexical research. Combining a cognitive linguistic interest in meaning with a sociolinguistic interest in variation, the authors illustrate this distributional methodology using case studies of Dutch and Spanish lexical data that focus on the detection of polysemy, the interaction of semasiological and onomasiological change, and sociolinguistic issues of lexical standardization and pluricentricity. Throughout, they highlight both the advantages and disadvantages of a distributional methodology: on the one hand, it has great potential to be scaled up for lexical research; on the other, its outcome does not necessarily neatly correspond with what would traditionally be considered different senses.
