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.

The early Spenser, 1554–80
'Minde on honour fixed'
by Jean R. Brink, Joshua Samuel Reid
Brink's provocative biography shows that Spenser was not the would-be court poet whom Karl Marx's described as 'Elizabeth's arse-kissing poet'. In this readable and informative account, Spenser is depicted as the protégé of a circle of London clergymen, who expected him to take holy orders. Brink shows that the young Spenser was known to Alexander Nowell, author of Nowell's Catechism and Dean of St. Paul's. Significantly revising the received biography, Brink argues that that it was Harvey alone who orchestrated Familiar Letters (1580). He used this correspondence to further his career and invented the portrait of Spenser as his admiring disciple. Contextualising Spenser's life by comparisons with Shakespeare and Sir Walter Ralegh, Brink shows that Spenser shared with Sir Philip Sidney an allegiance to the early modern chivalric code. His departure for Ireland was a high point, not an exile.

Walter Benjamins Archive
Bilder, Texte und Zeichen
by Erdmut Wizisla, Erdmut Wizisla, Walter Benjamin Archiv, Michael Schwarz, Ursula Marx, Gudrun Schwarz
Von einer Sensation ist zu berichten: Das Walter Benjamin Archiv zeigt eine Fülle von großartigen, in weiten Teilen bisher unpublizierten und auch unbekannten Bildern und Dokumenten. Anläßlich einer Ausstellung in der Akademie der Künste, Berlin, wird, begleitet von einer internationalen Tagung und einer Vielzahl von Veranstaltungen, zum ersten Mal Benjamins Bildund Dingkosmos der Öffentlichkeit vorgestellt. Solche Orientierung an Bildern und Dokumenten, an der Materialität der Gegenstände entspricht auch seinem Werk, das seinerseits ein Reservoir von Texten, Kommentaren, Elementen des Alltags, der Kunst und des Traums ist. Viele dieser Elemente sind als Bausteine in sein 'Passagen'-Projekt eingegangen, das die 'Urgeschichte des 19. Jahrhunderts ' erkundet. Darüber hinaus prägen Techniken des Sammelns und Archivierens die Arbeitsweise Walter Benjamins. Nachdem er aus Deutschland vertrieben worden war, schuf er die Voraussetzungen zur Rettung seiner, wie er sagte, 'unendlich verzettelten Produktion ', indem er Manuskripte, Notizen und Druckbelege bei Freunden in aller Welt deponierte Der reichillustrierte und kommentierte Band schließt erstmals Benjamins Archive auf: Notizhefte, in denen jeder Zentimeter genutzt wird; Register, Verzeichnisse und Karteien, die zugleich akribisch und kreativ geführt sind; Ansichtskarten, von ihm selbst kommentierte Fotoserien; eine Sammlung früher Worte und Sätze seines Sohnes Stefan, dessen Sprach- und Denkentwicklung Benjamin in Aufzeichnungen über Jahre verfolgte.

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.

Reading Walter Benjamin
Writing through the catastrophe
by Richard Lane
'Reading Walter Benjamin' explores the persistence of absolute in Benjamin's work by sketching-out the relationship between philosphy and theology apparent in his diverse writings, from the early youth-movement essays to the later books, essays and fragments. The book examines Benjamin from two main perspectives: a history-of-ideas approach situating Benjamin in relation to the new German-Jewish thinking at the turn of the twentieth-century, as well as the German youth movements, Surrealism and the 'Georgekreis'; and a conceptual approach examining more critical issues in relation to Benjamin and Kant, modern aesthetics and narrative order. Chapters cover: 'Kulturpessimismus' and the new thinking; metaphysics of youth: Wyneken and 'Rausch'; history: surreal Messianism; Goethe and the 'Georgekreis'; Kant's experience; casting the work of art; disrupting textual order; and exile and the time of crisis. The book uses new translations of Benjamin's essays, fragments and his 'Arcades Project', and makes substantial reference to previously untranslated material. Lane's text allows the non-specialist entry into complex areas of critical theory, simultaneously offering original readings of Benjamin and twentieth-century arts and literature. ;

Biotechnology 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.

Journey in Trumplandia: The Rise of Populism in America
by Tiberiu Dianu
The book is a collection of essays about the transformation of America, which has turned from a united nation to one more divided than ever. Some pundits predict that, if things don’t change, another civil war could occur. Have we reached a point of no return? Hopefully, America is mature enough to learn from its mistakes and avoid further scars along its evolving history. "Trumplandia is a welcome addition toward understanding current events, Washington’s international policy, and the present American society; a society polarized and divided as it has not been since the Civil War.” NICHOLAS DIMA, Ph.D., Adjunct Professor and Research Associate, Nelson Institute, James Madison University, Virginia. "The book is fascinating. It provides background to, and insights into [the] current and past political history as well as offering a personal view... of the country and society. Presented in thematic form in chapters and sections, the insights offered provide a suggestive radiography...” Dr. DENNIS DELETANT, OBE, School of Foreign Service, Georgetown University, Washington DC. "There has been this backsliding in... what a truly functioning rule-of-law state is, that has proper separation of co-equal powers, which, if you don’t keep working on that, you backslide. And I am even worried about that here, in the United States right now, about backsliding.” OBIE MOORE, Esq., OLM Advisors LLC, Washington DC “Indeed, Trumplandia should be a welcome addition to any scholar, student or layman’s library, especially in its international edition. If anyone loses sleep over its challenging assertions, then it will have been well worth it.” ERNESTO MORALES HIZON, Ph.D. Candidate in American and Comparative Politics at Claremont Graduate University, Member, Integrated Bar of the Philippines ABOUT THE AUTHOR: TIBERIU DIANU has practiced law in Romania (as a corporate lawyer, judge, senior counselor at the Ministry of Justice, university professor and senior legal researcher), and in the United States (as a legal expert for the judiciary). He published several books and a host of articles in law, politics, and post-communist societies. Tiberiu currently lives and works in Washington, DC.

Übersetzen: Walter Benjamin
by Christiaan Lucas Hart Nibbrig
In Übersetzen: Walter Benjamm wird anhand einer scheinbar randständigen Frage die intellektuelle Physiognomie Walter Benjamins beleuchtet. Der Band, der, passend zum Thema, einen internationalen Gesprächszusammenhang dokumentiert, gilt Walter Benjamin als Theoretiker des Übersetzens und als Übersetzer, der Schwierigkeit, ihn zu übersetzen, und vor allem auch der Frage des Über-Setzens, Umsetzens und Ersetzens: Grundfiguren seines philosophischen und literarischen Werks, die in solcher Eindringlichkeit erstmals fokussiert in den Blick gerückt und von verschiedenen Seiten aus angegangen werden.

Walter Benjamin
Eine Biographie
by Howard Eiland, Michael W. Jennings, Irmgard Müller, Ulrich Fries
Im ersten Satz erklärt dieses umfassende, facettenreiche Porträt Walter Benjamin zu einem »der wichtigsten Zeugen der europäischen Moderne«. Damit ist das Programm des Buches vorgegeben: Detailliert wird der Zeuge in seinen Suchbewegungen verfolgt, wie er in herausragender und parteiischer Form den Geist seiner Zeit artikuliert, schwankend zwischen Jugendbewegung, Zionismus, Marxismus und Messianismus. Benjamins Hoffnung, einmal »erstrangiger Kritiker der deutschen Literatur« zu werden, erfüllte sich zu Lebzeiten nicht. Subjektive Dispositionen und objektive Verhältnisse drängten diesen Autor zunehmend in eine randständige, wenngleich von Freunden und Bewunderern geachtete Existenz. Wirtschaftliche Not, Verfolgung und Flucht prägten seine letzten Lebensjahre. Die Auseinandersetzungen um die Deutungshoheit über Benjamins Werk (und Leben) setzten bald nach Kriegsende ein: Wer vollstreckte das Testament in seinem Sinne - Theodor W. Adorno oder Hannah Arendt? Gershom Scholem oder die Neomarxisten Berliner Prägung? Oder gar die Studentenbewegung? Die nun endlich in deutscher Sprache vorliegende, vielgerühmte und reich bebilderte Biographie verarbeitet sämtliches verfügbare Material in einer der Objektivität verpflichteten Weise und stellt auch die unterschiedlichen Haltungen zu Benjamin auf den Prüfstand. Sie gilt schon jetzt als Standardwerk.

Studien zur Philosophie Walter Benjamins
Mit einer Vorrede von Theodor W. Adorno
by Rolf Tiedemann, Theodor W. Adorno
1965 zuerst erschienen, blieb das Buch Tiedemanns bis heute die einzige umfassende Darstellung der Philosophie Walter Benjamins; seit längerem vergriffen, wird es jetzt unverändert wieder vorgelegt. Nach Tiedemann untersteht Benjamins Denken, so energisch es den Habitus aller Schulphilosophie abgestreift hat, dennoch einem spezifisch philosophischen Formgesetz. Mit der Einsicht in dieses Formgesetz, das in der Geschichte der Philosophie kaum schon vor Benjamin begegnet, fällt die in den Wahrheitsgehalt des Benjaminschen Werks zusammen. »Während Tiedemann sich auf einige zentrale Komplexe beschränkt und vor dem ominösen Ideal der Vollständigkeit hütet, ist es seiner Konzentration gleichwohl gelungen, die Einheit, den strengen Zusammenhang und die konstitutive Kraft des Benjaminschen Denkens darzutun. Nach dieser Arbeit wird es keinem mehr möglich sein, sich hinter das Argument zu verschanzen, das von Benjamin Inaugurierte sei aperçuhaft oder rhapsodischen Wesens.« »Theodor W. Adorno«

Speculation 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.

Walter Benjamin gehört zu den meistdiskutierten Autoren des 20. Jahrhunderts – in Wissenschaft, Literatur und Kunst. Seine eigenwilligen und unkonventionellen Schriften sind ein unablässiges Nachdenken über seine großstädtische, seine Berliner Herkunft: darüber, wie man sich im Labyrinth ständig wechselnder Eindrücke zurechtfinden kann.

Quarantine Pests for Europe
by Mark Holderness, Edited by D G McNamara, I M Smith, Peter R Scott.
Data sheets on quarantine pests for the European Union and for the European and Mediterranean Plant Protection Organization. This book is the result of collaboration between EPPO and CAB INTERNATIONAL, sponsored by the Commission of the European Union, to prepare data sheets on pests of plants of quarantine significance for Europe and the Mediterranean region. Coverage extends to insects, mites, fungi, bacteria, viruses, nematodes and parasitic plants. It includes organisms that are found outside Europe and the Mediterranean that present a risk to this region, as well as those that are present but have restricted distribution and are subject to phytosanitary controls. The format of the FAO model data sheet is followed, using standard headings: identity, hosts, geographical distribution, biology, detection and identification, means of movement and dispersal, pest significance (including economic impact, control and phytosanitary risk), phytosanitary measures, and bibliography. The first edition of this book was published in December 1992 and consisted of 188 data sheets, some covering groups of similar organisms. During the intervening four years pests have been added to the EU and EPPO lists and changes have occurred in host range, geographical distribution, taxonomy and pest status of many of the organisms described. All data sheets have therefore been revised, some data sheets covering groups of similar organisms have been split up and 56 new sheets added, resulting in a total of 300 data sheets. The second edition will continue therefore to represent a definitive reference source, not only for those with specific interests in plant quarantine, but also for all concerned with pest management.
