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 1986Briefe an Werner Kraft
by Gershom Scholem, Werner Kraft, Jörg Drews
"Die hier versammelten Briefe Gerhard Gershom Scholems sind zum allergrößten Teil Zeugnisse aus jungen Jahren; gerichtet an Werner Kraft, den heute in Jerusalem lebenden Dichter und homme de lettres. In jenen Jahren, die in diesen Briefen aufleuchten, nämlich den Jahren 1917 bis 1931, gab es für Scholem hauptsächlich eines zu tun: leidenschaftlich, unentwegt zu lernen, und zwar, so Werner Kraft, fast ausschließlich »bezogen auf das Studium der heiligen Schriften«. Wie Scholem derjenige wurde, dem man sein Botschaft glaubte, weil er sie vertrat – dies verdeutlichen diese Briefe an den Jugendfreund, der, mit weit größeren Schwierigkeiten, als Scholem sie hatte, ebenfalls zu »seinem« Judentum finden mußte."

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.

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.

Fertilizers & manuresNovember 2006No Tillage Seeding in Conservation Agriculture
by C J Baker, Scott E Justice, Keith E Saxton, Peter Hobbs, William R Ritchie, W C T Chamen, Don C Reicosky, Fatima Ribeiro
This book is a much-expanded and updated edition of a previous volume, published in 1996 as "No-tillage Seeding: Science and Practice". The base objective remains to describe, in lay terms, a range of international experiments designed to examine the causes of successes and failures in no-tillage. The book summarizes the advantages and disadvantages of no tillage. It highlights the pros and cons of a range of features and options, without promoting any particular product.Topics added or covered in more detail in the second edition include:* soil carbon and how its retention or sequestration interacts with tillage and no-tillage* controlled traffic farming as an adjunct to no-tillage* comparison of the performance of generic no-tillage opener designs* the role of banding fertilizer in no-tillage* the economics of no-tillage* small-scale equipment used by poorer farmers* forage cropping by no-tillage* a method for risk assessment of different levels of machine sophistication

April 2023Speculation by Commodity Index Funds
The Impact on Food and Energy Prices
by Scott H. Irwin, Dwight R. Sanders
Commodity futures prices exploded in 2007-08 and concerns about a new type of participant in commodity futures markets began to emerge. Market participants, regulators, and civic organizations began raising concerns that inflows from new "commodity index" investments were driving the increases in commodity prices instead of economic fundamentals. The main argument was that unprecedented buying pressure from these speculative long-only futures traders created massive bubbles that resulted in prices substantially exceeding fundamental value. At the time, it was not uncommon to link concerns about speculation and high prices to world hunger, food crises, and civil unrest. Naturally, this outcry resulted in numerous regulatory proposals to restrict speculation in commodity futures markets through transaction taxes, speculative position limits, and even the bizarre idea of a "virtual reserve" whereby a public agency would take futures positions opposite speculators. At the core, these assertions raised major economic questions about the efficiency of price discovery in commodity futures markets. Moreover, these so-called remedies did not come without a potential cost. Burdensome regulations would increase compliance and risk sharing costs across the global food system-lowering prices for producers and increasing costs to consumers. To guide this debate, a rigorous approach was needed to understand the dynamics between prices and commodity index activity. This book documents a curated selection of papers on the impact of index investment on commodity futures prices. The chronology of the papers roughly follows the timeline of our involvement in the world-wide debate about commodity speculation as it evolved after 2007. The 10 papers follow the evolving speculation debate with new author forwards highlighting the contribution and impact. Policy-makers, researchers, and market participants will find this not only as useful documentation of the debate; but, also a natural starting point when high commodity prices inevitably create the next speculation backlash.

BiotechnologyNovember 1996Biotechnology of Ornamental Plants
by Edited by R L Geneve, John E Preece, Scott A Merkle
Ornamental plants include herbaceous plants produced as bedding plants, greenhouse pot plants and cut flowers, as well as bulbs, trees, shrubs and vines. Ornamental plant production is of major and increasing importance worldwide. Basic scientific research in recent years has provided a better understanding of plant regeneration, genetics, growth and development. This has led to the development of technologies which can significantly improve ornamental species. This book reviews recent advances in the biotechnology of ornamentals. For example, genes have recently been identified for flower characteristics and pest resistance and these have been engineered into ornamental species. The book is divided into four main parts and is written by authors from the USA, UK, Canada, Netherlands, Australia and New Zealand. It is aimed primarily at workers in horticulture and plant biotechnology, but will also be of interest to plant physiologists, geneticists and molecular biologists.

Little People, Big Dreams. Deutsche Ausgabe | Kinderbuch ab 4 Jahre
by María Isabel Sánchez Vegara, Aaron Cushley, Silke Kleemann
Schon in der Schule hatte er ein Faible für alte Sprachen. Er lernte nicht nur Latein und Griechisch, sondern auch Alt- und Mittelenglisch. Und er malte Karten, auf denen er die Welt des Mittelalters wieder zum Leben erweckte. Später erfand der Professor für Sprachwissenschaft für seine Kinder fantastische Geschichten. Und so entstand die Welt der Hobbits, Elben, Zwerge und Zauberer - und die Saga vom »Herrn der Ringe«. Das Buch und seine Verfilmungen schlagen bis heute ein Millionenpublikum in Bann. Little People, Big Dreams erzählt von den beeindruckenden Lebensgeschichten großer Menschen: Jede dieser Persönlichkeiten, ob Philosophin, Forscherin oder Sportler, hat Unvorstellbares erreicht. Dabei begann alles, als sie noch klein waren: mit großen Träumen.
