Book Synopsis Variation by : Benedikt Hallgrímsson

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

Book Synopsis Variation and Evolution by : Sandro Sessarego

Download or read book Variation and Evolution written by Sandro Sessarego. This book was released on 2020-08-11. 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).

Book Synopsis Wood Variation by : Bruce J. Zobel

Download or read book Wood Variation written by Bruce J. Zobel. This book was released on 2012-12-06. 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.

Book Synopsis Linguistic Variation in Research Articles by : Bethany Gray

Download or read book Linguistic Variation in Research Articles written by Bethany Gray. This book was released on 2015-12-15. 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.
