Quantitative Corpus Linguistics with R
The first textbook of its kind, Quantitative Corpus Linguistics with R demonstrates how to use the open source programming language R for corpus linguistic analyses. Computational and corpus linguists doing corpus work will find that R provides an enormous range of functions that currently require several programs to achieve – searching and processing corpora, arranging and outputting the results of corpus searches, statistical evaluation, and graphing.
Statistics for Linguistics with R
This book is an introduction to statistics for linguists using the open source software R. It is aimed at students and instructors/professors with little or no statistical background and is written in a non-technical and reader-friendly/accessible style. It first introduces in detail the overall logic underlying quantitative studies: exploration, hypothesis formulation and operationalization, and the notion and meaning of significance tests. It then introduces some basics of the software R relevant to statistical data analysis. A chapter on descriptive statistics explains how summary statistics for frequencies, averages, and correlations are generated with R and how they are graphically repr...
Ten Lectures on Corpus Linguistics with R
In this book, Stefan Th. Gries provides an overview on how quantitative corpus methods can provide insights to cognitive/usage-based linguistics and selected psycholinguistic questions. Topics include the corpus linguistics in general, its most important methodological tools, its statistical nature, and the relation of all these topics to past and current usage-based theorizing. Central notions discussed in detail include frequency, dispersion, context, and others in a variety of applications and case studies; four practice sessions offer short introductions of how to compute various corpus statistics with the open source programming language and environment R.
Gas Chromatography
A single source of authoritative information on all aspects of the practice of modern gas chromatography, from theory, to methods, to selected applications. It also provides access to core data for practical work, comparison of results, and decision making and facilitates the search for sources in related areas of study.

Selected Topics in the Chemistry of Natural Products
Labor is the most important of the three traditional factors of production (land, labor and capital), accounting for some 75 per cent of the GDP. It is therefore important to focus on issues of labor economics. In this book the approach taken will be that of the free market philosophy of libertarianism, the perspective that allows the maximum of freedom, consistent with the responsibility of all to respect the equal rights of all others. The position of this book on unions is unique outside of the libertarian movement, and this is indicative of its analysis of several other issues, such as minimum wages. For scholars on the left, it is almost true that unions can do no wrong (for Marxists, t...
Contrast Agents I
Extracellular MRI and X-ray contrast agents are characterized by their phar- cokinetic behaviour.After intravascular injection their plasma-level time curve is characeterized by two phases. The agents are rapidly distributed between plasma and interstitial spaces followed by renal elimination with a terminal half-live of approximatly 1–2 hours. They are excreted via the kidneys in unchanged form by glomerular filtration. Extracellular water-soluble contrast agents to be applied for X-ray imaging were introduced into clinical practice in 1923. Since that time they have proved to be most valuable tools in diagnostics.They contain iodine as the element of choice with a sufficiently high atomic weight difference to organic tissue. As positive contrast agents their attenuation of radiation is higher compared with the attenuation of the surrounding tissue. By this contrast enhancement X-ray diagnostics could be improved dramatically. In 2,4,6-triiodobenzoic acid derivatives iodine is firmly bound. Nowadays diamides of the 2,4,6-triiodo-5-acylamino-isophthalic acid like iopromide (Ultravist, Fig. 1) are used as non-ionic (neutral) X-ray contrast agents in most cases [1].
Diabetes and Cardiovascular Disease
This extensively updated and expanded second edition reflects new research, advances in clinical care, and the growing recognition that diabetes mellitus is a risk factor for cardiovascular disease. Written for the practicing clinician as a comprehensive review of diabetic vascular disease, the book both explains the basic pathophysiology of the disease and details the latest diagnostic and therapeutic approaches. The authors have added new chapters on percutaneous interventional therapy in cardiac and peripheral vascular disease, cardiovascular surgery in diabetes, therapeutic interventions to improve endothelial function in diabetes, PARP activation and nitrosative stress in the development of the cardiovascular system, and PPARs and their emerging role in vascular biology, inflammation, and atherosclerosis.
