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.

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.

HorticultureFebruary 2009Potatoes Postharvest
by R T Pringle, C F H Bishop, R C Clayton
A wider understanding of potato postharvest practices is needed to improve working relations between growers, agronomists, pathologists and crop store managers. Providing a comprehensive examination of international potato production, this book identifies which storage systems suit particular climatic zones as well as considering interactions between crop microclimate, dehydration, crop cooling, condensation and disease development. Potatoes Postharvest will guide the reader through the activities following harvest from store loading, store management, and grading to packaging and dispatch.

February 2024Experimental Design and Analysis for Tree Improvement
by Emlyn Williams, Chris Harwood, Colin Matheson
This third edition of Experimental Design and Analysis for Tree Improvement provides a set of practical procedures to follow when planning, designing and analysing tree improvement trials. Using many fully worked examples, it outlines how to: design field, glasshouse and laboratory trials; efficiently collect and construct electronic data files; pre-process data, screening for data quality and outliers; analyse data from single and across-site trials; and interpret the results from statistical analyses. The authors address the many practical issues often faced in forest tree improvement trials and describe techniques that will efficiently give conclusive results. The techniques provided are applicable to the improvement of not only trees, but to crops in general. Building on the success of the second edition, this new edition has been fully revised to include the construction of p-rep and spatial designs using the commercially available software package for design generation (CycDesigN). For analysis of the examples, it provides online Genstat and SAS programs and a link to R programs.

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.
