        UV-B Radiation and Plant Life

        Molecular Biology to Ecology

        by Brian R Jordan, Pedro J. Aphalo, Amy T. Austin, Carlos L. Ballaré, Paul W. Barnes, Susanne Baldermann, Melanie Binkert, Janet F. Bornman, Isabelle N. Bottger, Stephan D. Flint, Franziska S. Hanschen, Éva Hideg, Marcel A K Jansen, Gareth I. Jenkins, Karel Klem, Susanne Neugart, Monika Schreiner, Åke Strid, Mark A.

        Ultraviolet-B radiation (UV-B) has profound effects on plant growth and development, and exposure varies with ozone depletion and across geographic regions, with ecosystem and agricultural consequences. This book deals with large-scale impacts but also how UV-B affects plants at the molecular level is also fascinating, and the UV-B photoreceptor has only recently been characterised. While UV-B radiation can be damaging, it also has a more positive role in plant photomorphogenesis. Consequently UV-B treatments are being developed as innovative approaches to improve horticulture. This book is a timely synthesis of what we know and need to know about UV-B radiation and plants.

        Practical R for Biologists

        An Introduction

        by Donald Quicke, Buntika A Butcher, Rachel Kruft Welton

        R is a freely available, open-source statistical programming environment which provides powerful statistical analysis tools and graphics outputs. R is now used by a very wide range of people; biologists (the primary audience of this book), but also all other scientists and engineers, economists, market researchers and medical professionals. R users with expertise are constantly adding new associated packages, and the range already available is immense.This text works through a set of studies that collectively represent almost all the R operations that biology students need in order to analyse their own data. The material is designed to serve students from first year undergraduates through to those beginning post graduate levels. Chapters are organized around topics such as graphing, classical statistical tests, statistical modelling, mapping, and text parsing. Examples are based on real scientific studies, and each one covers the use of more R functions than those simply necessary to get a p-value or plot.The book walks the reader through the data analysis process, starting with very simple plots, and continuing through more complex analyses and programming. It shows how to deal with issues such as error messages that can be confronting for beginners, in order to set students up for a successful scientific career using R.Collectively the authors have a vast amount of teaching experience which they apply here to make the passage into R programming as gentle and easy as possible, whilst guiding the reader to tackle quite complicated programming. Table of contents 1: How to Use this Book 2: Installing and Running R 3: Very Basic R Syntax 4: First Simple Programs and Graphics 5: The Dataframe Concept 6: Plotting Biological Data in Various Ways 7: The Grammar of Graphics Family of Packages 8: Sets and Venn diagrams 9: Statistics: Choosing the Right Test 10: Commonly Used Measures and Statistical Tests 11: Regression and Correlation Analyses 12: Count Data as Response Variable 13: Analysis of Variance (ANOVA) 14: Analysis of Covariance (ANCOVA) 15: More Generalised Linear Modelling 16: Monte Carlo Tests and Randomisation 17: Principal Components Analysis 18: Species Abundance, Accumulation and Diversity Data 19: Survivorship 20: Dates and Julian Dates 21: Mapping and Parsing Text Input for Data 22: More on Manipulating Text 23: Phylogenies and Trees 24: Working with DNA Sequences and other character data 25: Spacing in Two Dimensions 26: Population Modelling Including Spatially Explicit Models 27: More on “apply” Family of Functions – Avoid Loops to get More Speed 28: Food webs and simple graphics 29: Adding Photographs 30: Standard Distributions in R 31: Reading and Writing Data to and from Files

        The Best of H. C. Artmann

        by H. C. Artmann, Klaus Reichert

        Von allen deutschen Autoren, die nach 1945 zu schreiben begannen, ist Artmann ohne jeden Zweifel der vielseitigste, originellste und erfinderischste. So wie Artmann in fast allen Gattungen gearbeitet hat, auch den angeblich antiquierten, und ohne sich um die Tagesparolen der mal reine Dichtung betreibenden, mal engagierten, mal die Literatur totsagenden Kollegen zu kümmern, so hat er seine Quellen, seine Herkunft überall: in der Artusepik, in barocker Schäferpoesie, in den Wörterbüchern und Grammatiken von gut zwei Dutzend Sprachen, in Irland und im England des Sherlock Holmes, bei Villon und dem Wiener Vorstadtdialekt, Lorca, Gomez de la Serna, den Surrealisten und Dadaisten, in den Detektivheftchen der 20er Jahre und den Comic strips von damals bis heute. Unsere Auswahl versucht, nicht nur einen repräsentativen Querschnitt durch das Werk Artmanns zu geben, sondern gleichzeitig Verstreutes, an entlegensten Orten Publiziertes zu sammeln.

        A history of English spelling

        by D. G. Scragg

        This book provides an outline history of English spelling from the Anglo-Saxon' adoption of the Roman alphabet to the present day. It shows the respective influences on modern usage of native French and Latin orthographies and attempts a definition of the manner in which spelling stabilised. A final chapter traces changing notions of correctness in spelling during the last four centuries, and also gives a summary of the principle movements for its reform in favour of a more consistent and phonetic system of notion. Students in higher education specialising in English or linguistics and also those studying other languages at an advanced level should find this a useful book. The general reader with an interest in the history of his language or the question of spelling will find it most readable ;

        Intentionalität

        Eine Abhandlung zur Philosophie des Geistes

        by Harvey P. Gavagai, John R. Searle

        Nach seinen sprachphilosophischen Arbeiten ('Sprechakte', stw 458; 'Ausdruck und Bedeutung', stw 349) hat John R. Searle mit 'Intentionalität' eine Untersuchung zu einem Kernstück der Philosophie des Geistes vorgelegt, die in einem engen thematischen Zusammenhang mit den früheren Arbeiten steht. Intentionalität ist nach Searles Auffassung die Basis sprachlicher Bedeutung. In seiner Theorie der Intentionalität geht es um die begrifflichen Eigenschaften intentionaler Zustände (auf die Frage nach ihrem ontologischen Status geht er ausführlicher ein in 'Geist, Hirn und Wissenschaft', stw 591). Zwei Aspekte stehen dabei im Vordergrund der Untersuchung: die Logik der Repräsentation und der Kausalität intentionaler Zustände. Doch Searle entwickelt in dieser Arbeit nicht nur eine Theorie der Intentionalität und des Zusammenhangs zwischen sprachlichem und geistigem Inhalt. In einem vornehmlich kritischen Teil setzt er sich ausführlich mit konkurrierenden Auffassungen aus dem Bereich der analytischen Philosophie auseinander, insbesondere mit derzeit sehr einflußreichen 'nicht-deskriptivistischen' Theorien des Bezugs, wie sie von S. Kripke, H. Putnam, K. Donnellan, T. Burge und D. Kaplan vertreten und angeregt wurden.

        A concordance to the rhymes of The Faerie Queene

        by Richard Brown, J. B. Lethbridge, J. B. Lethbridge

        This book is the first ever concordance to the rhymes of Spenser's epic. It gives the reader unparalleled access to the formal nuts and bolts of this massive poem: the rhymes which he used to structure its intricate stanzas. As well as the main concordance to the rhymes, the volume features a wealth of ancillary materials, which will be of value to both professional Spenserians and students, including distribution lists and an alphabetical listing of all the words in The Faerie Queene. The volume breaks new ground by including two studies by Richard Danson Brown and J. B. Lethbridge, so that the reader is given provocative analyses alongside the raw data about Spenser as a rhymer. Brown considers the reception of rhyme, theoretical models and how Spenser's rhymes may be reading for meaning. Lethbridge in contrast discusses the formulaic and rhetorical character of the rhymes. ;

        by Márcia Leite

        Humans, who hold the power and exercise it for their own benefit, do not see the other beings of that universe. The invisibility and the political and social relations of micro and macro powers are intertwined in the maximum of coexistence and coexistence between different beings in a common territory.
