Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: This book is a collection of original studies analyzing how different internal and external factors affect Spanish language variation and evolution across a number of (socio)linguistic scenarios. Its primary goal is to expand our understanding of how native and non-native varieties of Spanish co-exist with other languages and dialects under the influence of several linguistic and extra-linguistic forces. While some papers analyze the linguistic dynamics affecting Spanish grammars from a cross-dialectal perspective, others focus more closely on the relations established between Spanish and other languages with which it is in contact. In particular, some of these studies show how power and prestige may support (or not) the use of Spanish in different social contexts and educational realities, given that the attitudes toward this language vary greatly across the Spanish-speaking world. On the one hand, in some regions, Spanish represents the variety spoken by the majority of the population, typically related to prestige and power (Spain and Latin America). On the other hand, in other contexts, the same language is conceived as a minority variety, which may or may not be associated with stigmatized immigrant groups (i.e., in the US).

Download or read book Wood Variation written by Bruce J. Zobel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood is the usual end product of a forestry operation. Because of its importance, numerous studies have been made relative to wood prop erties, the causes of wood variation, and how best to develop wood for desired products. There is voluminous literature related to these subjects, but it is neither well known nor appreciated by foresters because the publications are often not available or are not well understood by the forester or by those who use the wood. Frequently, the literature is confusing and contradictory, making it difficult for the nonspecialist to use what information is available. In order to produce and use wood efficiently, the variation pat terns within trees, among trees within species, and among species must be understood. This also requires some knowledge of the causes of variation and the effects of different wood properties upon utiliza tion. The information about variation patterns, their causes, and con trol and effect upon the product must be known by the tree grower, the tree breeder, and the tree harvester as well as by those who ultimately convert wood into a final, salable product.

Download or read book Linguistic Variation in Research Articles written by Bethany Gray and published by John Benjamins Publishing Company. This book was released on 2015-12-15 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Linguistic Variation in Research Articles investigates the linguistic characteristics of academic research articles, going beyond a traditional analysis of the generically-defined research article to take into account varied realizations of research articles within and across disciplines. It combines corpus-based analyses of 70+ linguistic features with analyses of the situational, or non-linguistic, characteristics of the Academic Journal Registers Corpus: 270 research articles from 6 diverse disciplines (philosophy, history, political science, applied linguistics, biology, physics) and representing three sub-registers (theoretical, quantitative, and qualitative research). Comprehensive analyses include a lexical/grammatical survey, an exploration of structural complexity, and a Multi-Dimensional analysis, all interpreted relative to the situational analysis of the corpus. The finding that linguistic variation in research articles does not occur along a single parameter like discipline is discussed relative to our understanding of disciplinary practices, the multidimensional nature of variation in research articles, and resulting methodological considerations for corpus studies of disciplinary writing.

Download or read book Variations written by Juliet Jacques and published by Influx Press. This book was released on 2021-06-17 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Jacques's voice sings out loud and clear – wistful, drily humorous, stiletto-sharp.' – The Observer Variations is the debut short story collection from one of Britain's most compelling voices, Juliet Jacques. Using fiction inspired by found material and real-life events, Variations explores the history of transgender Britain with lyrical, acerbic wit. Variations travels from Oscar Wilde's London to austerity-era Belfast via inter-war Cardiff, a drag bar in Liverpool just after the decriminalisation of homosexuality, Manchester's protests against Clause 28, and Brighton in the 2000s. Through diary entries of an illicit love affair, an oral history of a contemporary political collective; a 1920s academic paper to a 1990s film script; a 1950s memoir to a series of 2014 blog posts, Jacques rewrites and reinvigorates a history so often relegated to stale police records and sensationalist news headlines. Innovative and fresh, Variations is a bold and beautiful book of stories unheard; until now. 'Everything about this book—from the conception, to the language, to the execution—makes me wish I'd been the one to write it. Except I couldn't have. Juliet Jacques is a complete original and this book is the proof.' – Torrey Peters

Available in PDF, EPUB and Kindle. Book excerpt: This book was first published in 1960 as No. 5 of Volume 49 of Reports of the Forest Research Institute of Sweden. It was at the same time a doctor's thesis in mathematical statistics at Stockholm University. In the second edition, a number of misprints and other errors have been corrected. An author index and a subject index have been added. Finally, a new postscript comments on the later development of the subjects treated in the book. BERTIL MATERN March r¢6 Acknowledgements The completion of this thesis was facilitated through the generous assist ance of several persons and institutions. I would wish to express my sincere gratitude to my teacher, Professor HARALD CRAMtR, now chancellor of the Swedish universities, for his valuable help and encouragement. Sincere thanks are also offered to Professor ULF GRENANDER for kindly reading the first version of the manuscript and giving valuable advice. The thesis has been prepared during two widely separated periods. A preliminary draft of Ch. 2 was written in 1948, whereas the remaining parts were completed in 1959-1960. The work originates from problems which I discussed in a publication in 1947. The problems were assigned to me by Professor MANFRED NASLUND, former head of the Swedish Forest Research Institute, now governor of the province Norrbotten. It is a pleasure to acknowledge my gratefulness to Professor Naslund for his un remitting encouragement and interest in my work.

Download or read book Understanding English Language Variation in U S Schools written by Anne H. Charity Hudley and published by Teachers College Press. This book was released on 2015-04-26 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book Variation across Speech and Writing written by Douglas Biber and published by Cambridge University Press. This book was released on 1991-12-19 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Similarities and differences between speech and writing have been the subject of innumerable studies, but until now there has been no attempt to provide a unified linguistic analysis of the whole range of spoken and written registers in English. In this widely acclaimed empirical study, Douglas Biber uses computational techniques to analyse the linguistic characteristics of twenty three spoken and written genres, enabling identification of the basic, underlying dimensions of variation in English. In Variation Across Speech and Writing, six dimensions of variation are identified through a factor analysis, on the basis of linguistic co-occurence patterns. The resulting model of variation provides for the description of the distinctive linguistic characteristics of any spoken or written text andd emonstrates the ways in which the polarization of speech and writing has been misleading, and thus enables reconciliation of the contradictory conclusions reached in previous research.

Download or read book Genetic Variation and Human Disease written by Kenneth M. Weiss and published by Cambridge University Press. This book was released on 1993 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book A First Course in the Calculus of Variations written by Mark Kot and published by American Mathematical Society. This book was released on 2014-10-06 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended for a first course in the calculus of variations, at the senior or beginning graduate level. The reader will learn methods for finding functions that maximize or minimize integrals. The text lays out important necessary and sufficient conditions for extrema in historical order, and it illustrates these conditions with numerous worked-out examples from mechanics, optics, geometry, and other fields. The exposition starts with simple integrals containing a single independent variable, a single dependent variable, and a single derivative, subject to weak variations, but steadily moves on to more advanced topics, including multivariate problems, constrained extrema, homogeneous problems, problems with variable endpoints, broken extremals, strong variations, and sufficiency conditions. Numerous line drawings clarify the mathematics. Each chapter ends with recommended readings that introduce the student to the relevant scientific literature and with exercises that consolidate understanding.

Download or read book Aspects of Linguistic Variation written by Daniël Olmen and published by Walter de Gruyter GmbH & Co KG. This book was released on 2018-12-03 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Linguistic variation is a topic of ongoing interest to the field. Its description and its explanations continue to intrigue scholars from many different backgrounds. By taking a deliberately broad perspective on the matter, covering not only crosslinguistic and diachronic but also intralinguistic and interspeaker variation and examining phenomena ranging from negation over connectives to definite articles in well- and lesser-known languages, the volume furthers our understanding of variation in general. The papers offer new insights into, among other things, the theoretical notion of comparative concepts, the social or mental nature of language structure, the areal factor in lexical typology and the diachronic implications of semantic maps. The collection will thus be of relevance to typologists and historical linguists, as well as to people studying variation within the areas of cognitive and functional linguistics.
