        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.

        Cinema - Italy

        by Stefania Parigi, Des O'Rawe

        A journey to the Italian cinema that overturns established views and opens up new perspectives and interpretations. Its itinerary is organized in four stages. The first is an analysis of the theories of Cesare Zavattini on neorealism which overturns widely accepted positions both on Zavattini and on neorealism. The second confronts a key film of the post-war Italian cinema, Roberto Rossellini's Paisà, by examining the nature of its realism. The third is dedicated to Luchino Visconti: to questions of the use of language exemplified in his La terra trema, the use of settings, costume and light as agents of meaning in his Il Gattopardo and Vaghe stelle dell'Orsa. The final voyage of the film is to the physical and symbolic construction of heaven and earth in the work of Pasolini. Particular attention is given to the representation of the body in his last four films: the grotesque and mythical bodies in popular tradition in his Trilogia di vita and the tortured bodies destroyed by the mass media in Salò. ;

        Heterobasidion annosum

        Biology, Ecology, Impact and Control

        by Edited by Steven Woodward, J Stenlid, R Karjalainen, A Hüttermann

        The fungus Heterobasidion annosum is, in economic terms, the most important causal agent of disease and of yield loss in coniferous trees in northern temperate regions. This is the first book which brings together and summarises the considerable amount of knowledge which has been gathered about all aspects of this disease. It has been prepared and published with support from the European Union, under the Agriculture and Agro- Industrial Research (AAIR) programme. Drawing on over 2,000 research papers and books published from the early nineteenth century to the present day, the book covers topics which include the history, detection, biology, taxonomy and distribution of H. annosum. It provides the latest information on infection, host resistance, the biochemistry of the host-parasite interaction, molecular and genetic regulation of the host response and methods of control. It concludes with a series of case studies from Europe and North America. This book is an indispensable source of information for all those involved in the management of coniferous forests and plantations wishing to reduce the impact of this disease on yields. It should also become the accepted text for students of forestry and plant pathology studying H. annosum, and an invaluable reference manual for scientists researching this, and other fungal tree diseases.

        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.

        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.

        Milk Composition, Production and Biotechnology

        by Edited by Robert A S Welch, Donald J W Burns, Stephen R Davis, A I Popay, Colin G Prosser

        Major changes have recently taken place in the value attached to components of milk. Although approximately half the energy in milk is contained in fat, fat is rapidly decreasing in value relative to protein. This has come about because of the increased availability of competitively-priced, plant-derived edible oils and because of the perceived health problems associated with animal fat in the human diet. Such changes have major implications for the dairy sector, particularly in developed countries. Against this background, this book presents a timely review of developments in milk production and consumption, of changes in milk component values, and of the opportunities that biotechnology provides to alter the composition of and add value to milk on the farm. The subject coverage is very broad, ranging from nutritional aspects of pastures and forages, to rumen microbiology, genetics and reproductive technologies, milk biochemistry and environmental implications. It is based on a conference held in Wellington, New Zealand, in February 1996 and sponsored by the OECD and AgResearch. Contributors include leading research workers from North America, Europe, Japan, Australia and New Zealand. It provides an invaluable overview of the subject, suitable as a reference book for advanced students, researchers and advisers in dairy science as well as related disciplines such as grassland, nutritional and food sciences.

        Potato Cyst Nematodes

        Biology, Distribution and Control

        by Edited by R J Marks, Bill B Brodie

        The two closely related species of Potato Cyst-Nematodes (PCN), Globodera rostochiensis (Woll.) and Globodera pallida Stone have a worldwide distribution. Both are internationally recognized plant quarantine organisms of actual or potential major economic importance wherever potatoes are grown or traded. They occur in large soil masses and also adhere to potato tubers as microscopic cysts, which represent a complex of morphologically identical, but behaviourally different virulence groups, or pathotypes. This presents major problems for their detection, identification and management.This book is a synthesis of current practical knowledge and underpinning scientific research on PCN globally. It is arranged in five sections, comprising nineteen chapters by leading practitioners and research nematologists, in which the biology, detection, identification and control options (including plant resistance) for PCN are examined. In addition, its worldwide status is considered, including South America, where PCN co-evolved with its potato host. Essential information is provided for professionals and advanced students of plant nematology and crop protection.

        Gene-for-Gene Relationship in Plant-Parasite Interactions

        by Edited by Ian R Crute, Eric B Holub, Jeremy J Burdon

        Genetics has transformed plant pathology on two occasions: first when Mendelian genetics enabled the discovery that disease resistance was a heritable trait in plants, and secondly when Flor proposed the “gene-for-gene” hypothesis to explain his observations of plant-parasite interactions, based on his work on flax rust in North Dakota starting in the 1930s. Our knowledge of the genetics of disease resistance and host-pathogen coevolution is now entering a new phase as a result of the cloning of the first resistance genes. This book provides a broad review of recent developments in this important and expanding subject. Both agricultural and natural host-pathogen situations are addressed. While most of the book focuses on plant pathology, in the usual sense of the term embracing fungal, bacterial and viral pathogens, there is also consideration of parasitic plants and a chapter demonstrating lessons to be learnt from the mammalian immune system. Three overall themes are addressed: genetic analyses and utilization of resistance; population genetics; and cell biology and molecular genetics. Chapters are based on papers presented at the British Society for Plant Pathology Presidential meeting held in December 1995, but all have been revised and updated to mid-1996. Written by leading authorities from North America, Europe and Australia, the book represents an essential update for workers in plant genetics, breeding, biotechnology and pathology.

        Grass for Dairy Cattle

        by Edited by Jerome H Cherney, Debbie J R Cherney

        With the current interest in the environmental and economic sustainability of dairy farming, grass forage crops have emerged as a potential solution to some of the nutrient management problems now encountered on intensively managed dairy farms. The expansion and reintegration of grass-based systems into the mainstream of dairying systems will require a major paradigm shift involving economic, social and ecological, as well as biological factors.This book examines the role of grass in milk production in sustainable agricultural ecosystems. It provides a current summary of the role of grass in dairy cattle systems, including the breeding, management, storage, feeding and economics of grass for both lactating and dry dairy cows. Written by leading specialists from Australia, Europe, New Zealand, North and South America, this is an essential reference source for researchers, dairy industry professionals and advanced students of forage and dairy cattle nutrition.

        Common Agricultural Policy, 2nd Edition

        by Edited by Christopher Ritson, David R Harvey

        The first edition of this book, published in 1991 with the title The Common Agricultural Policy and the World Economy, was well received as a timely analysis of this fast-moving but important subject. However, several major developments, such as general CAP reform, the General Agreement on Tariffs and Trade (GATT), expansion of the European Union, and relationships with eastern Europe, have justified the need for a new edition. As a result, the book has been thoroughly updated, with some completely new chapters added and others replaced. It has also be rewritten with a greater emphasis on the needs of students for a well-integrated, comprehensive textbook.
