January 2021Practical 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.

May 1991Intentionalität
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.

2020Vitamin D
The healing power of the sunshine vitamin
by Uwe Gröber and Prof. Dr. Michael F. Holick
Vitamin D deficiency is a global health problem that puts the quality of life and life expectancy of more than a billion children and adults at risk worldwide. Many lifestyle diseases may be associated with vitamin D deficiency: myocardial infarction, infections, cancer, neurological diseases, stroke, type 2 diabetes, to name just a few. This 4th updated edition incorporates numerous new insights into the therapeutic effect of vitamin D, including its importance for a healthy pregnancy, prenatal imprinting, optimum sporting performance, diabetes mellitus and autoimmune diseases such as Hashimoto’s thyroiditis or multiple sclerosis. Since the metabolism and the effect of vitamin D are supported by a complex network of micronutrients – for example, magnesium, vitamin A or vitamin K – a specific chapter is devoted to this network. Here, the reader can discover how vitamin D successfully protects against diseases, improves the quality of life and optimises medication and treatment!

September 1975The 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.

European historyOctober 2013Popular science and public opinion in eighteenth-century France
by Michael R. Lynn
Now available in paperback, Michael R. Lynn's book analyses the popularisation of science in Enlightenment France. He examines the content of popular science, the methods of dissemination, the status of the popularisers and the audience, and the settings for dissemination and appropriation. Lynn introduces individuals like Jean-Antoine Nollet, who made a career out of applying electric shocks to people, and Perrin, who used his talented dog to lure customers to his physics show. He also examines scientifically oriented clubs like Jean-François Pilâtre de Rozier's Musée de Monsieur which provided locations for people interested in science. Phenomena such as divining rods, used to find water and ores as well as to solve crimes; and balloons, the most spectacular of all types of popular science, demonstrate how people made use of their new knowledge. Lynn's study provides a clearer understanding of the role played by science in the Republic of Letters and the participation of the general population in the formation of public opinion on scientific matters.

K u n s t / A n g s t EIN ÜBERLEBENSHANDBUCH FÜR DEN KÜNSTLER Von DAVID BAYLES & TED ORLAND Worum geht es bei Kunst? Wohin bewegt sie sich? Welche Widerstände gibt es? DAS SIND DIE FRAGEN, AUF DIE ES ANKOMMT, wiederkehrende Fragen, die sich in jedem Stadium der künstlerischen Entwicklung stellen. Sie sind der Ursprung für dieses Kompendium scharfsinniger Beobachtungen. Kunst & Angst erforscht, wie Kunst geschaffen wird, die Gründe, warum Kunstwerke oft nicht entstehen und die Art der Schwierigkeiten, die so viele Künstler dazu bringt, auf der Wegstrecke aufzugeben. Dieses Buch handelt davon, was du fühlst, wenn du in deinem Atelier oder im Lehrsaal sitzt, du an der Töpferscheibe oder am Keyboard, vor der Staffelei oder hinter deiner Kamera stehst und du versuchst, das Werk, das dir bestimmt ist, zu schaffen. Es geht darum, dass du deine Zukunft in die Hand nimmst, den Freien Willen über Vorherbestimmung, die Wahl vor den Zufall stellst. Es geht darum, dein eigenes Werk zu finden.

Teaching, Language & ReferenceAugust 2011A 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 ;

April 1996The Best of H. P. Lovecraft
by H. P. Lovecraft, Rudolf Hermstein, H. C. Artmann
Mit seinem Cthulu-Mythos wollte H. P. Lovecraft eine Atmosphäre kosmischen Grauens schaffen, die Archaisches mit den modernen Erkenntnissen der Wissenschaft verbindet und unserer Zeit angemessen ist. Die Angst hielt er für das älteste und stärkste Gefühl, mit dem er in seinen Erzählungen gerne spielte. Die besten Erzählungen von H. P. Lovecraft sind in diesem Rand zusammengefaßt.
