Focussing on professional politicians Klaus Stolz investigates the interrelationship between political career patterns and political institutions in two of the most widely discussed cases of regionalism: Catalonia and Scotland. The study deals with two different yet closely related sets of questions: Firstly, how do professional politicians pursue their careers in the regional context. And secondly, how do they shape and reshape the political institutions in which they pursue these careers. The monograph is based on extensive empirical research including a comprehensive data set on the careers of Catalan and Scottish parliamentarians, systematic surveys of regional representatives as well as in-depth interviews of a wide range of politicians and experts in both regions. Exploring the effects of political professionalisation on regional democracy, Stolz goes way beyond traditional studies of regionalism and decentralization, while his focus on the regional career arena introduces a much needed territorial dimension to the study of political careers. Rich original data, innovative theoretical concepts and a strictly comparative approach are the basis for a study that considerably deepens and enhances our understanding of the tremendous political changes both Catalonia and Scotland are undergoing. Thus, the book is of interest to the still growing number of scholars concerned with devolution in the UK, the Spanish autonomous communities as well as to those interested in regional politics and regionalisation in general. Furthermore, its theoretical focus makes it highly relevant for scholars working on political careers, political professionalisation and democratic theory.
This up-to-date monograph provides a thorough review of the relevant data and properties of the transition-metal impurities generated during silicon-sample and device fabrication. The different mechanisms responsible for contamination are discussed, and a survey is given of their impact on device performance. The specific properties of the main and rare impurities in silicon are examined, as well as the detection methods and requirements in modern technology. This new edition includes important recent data and many new tables.
This book presents an up-to-date formalism of non-equilibrium Green's functions covering different applications ranging from solid state physics, plasma physics, cold atoms in optical lattices up to relativistic transport and heavy ion collisions. Within the Green's function formalism, the basic sets of equations for these diverse systems are similar, and approximations developed in one field can be adapted to another field. The central object is the self-energy which includes all non-trivial aspects of the system dynamics. The focus is therefore on microscopic processes starting from elementary principles for classical gases and the complementary picture of a single quantum particle in a random potential. This provides an intuitive picture of the interaction of a particle with the medium formed by other particles, on which the Green's function is built on.
Since the appearance of its first edition in Germany in 1979, A History of German Literature has established itself as a classic work used by students and anyone interested in German literature. The volume chronologically traces the development of German literature from the Middle Ages to the present day. Throughout this chronology, literary developments are set in a social and political context. This includes a final chapter, written for this latest edition, on the consequences of the reunification of Germany in 1990. Thoroughly interdiscipinary in method, the work also reflects recent developments in literary criticism and history. Highly readable and stimulating, A History of German Literature succeeds in making the literature of the past as immediate and engaging as the works of the present. It is both a scholary study and an invaluable reference work for students.
This book presents applications of hypercomplex analysis to boundary value and initial-boundary value problems from various areas of mathematical physics. Given that quaternion and Clifford analysis offer natural and intelligent ways to enter into higher dimensions, it starts with quaternion and Clifford versions of complex function theory including series expansions with Appell polynomials, as well as Taylor and Laurent series. Several necessary function spaces are introduced, and an operator calculus based on modifications of the Dirac, Cauchy-Fueter, and Teodorescu operators and different decompositions of quaternion Hilbert spaces are proved. Finally, hypercomplex Fourier transforms are studied in detail. All this is then applied to first-order partial differential equations such as the Maxwell equations, the Carleman-Bers-Vekua system, the Schrödinger equation, and the Beltrami equation. The higher-order equations start with Riccati-type equations. Further topics include spatial fluid flow problems, image and multi-channel processing, image diffusion, linear scale invariant filtering, and others. One of the highlights is the derivation of the three-dimensional Kolosov-Mushkelishvili formulas in linear elasticity. Throughout the book the authors endeavor to present historical references and important personalities. The book is intended for a wide audience in the mathematical and engineering sciences and is accessible to readers with a basic grasp of real, complex, and functional analysis.
A symbol of modernity, the Viennese Secession was defined by the rebellion of twenty artists who were against the conservative Vienna Künstlerhaus' oppressive influence over the city, the epoch, and the whole Austro-Hungarian Empire. Influenced by Art Nouveau, this movement (created in 1897 by Gustav Klimt, Carl Moll, and Josef Hoffmann) was not an anonymous artistic revolution. Defining itself as a “total art”, without any political or commercial constraint, the Viennese Secession represented the ideological turmoil that affected craftsmen, architects, graphic artists, and designers from this period. Turning away from an established art and immersing themselves in organic, voluptuous, and decorative shapes, these artists opened themselves to an evocative, erotic aesthetic that blatantly offended the bourgeoisie of the time. Painting, sculpture, and architecture are addressed by the authors and highlight the diversity and richness of a movement whose motto proclaimed “for each time its art, for each art its liberty” – a declaration to the innovation and originality of this revolutionary art movement.
We bring to bear a hand-collected dataset of executive turnovers in U.S. banks to test the efficacy of market discipline in a 'laboratory setting' by analyzing banks that are less likely to be subject to government support. Specifically, we focus on a new face of market discipline: stakeholders' ability to fire an executive. Using conditional logit regressions to examine the roles of debtholders, shareholders, and regulators in removing executives, we present novel evidence that executives are more likely to be dismissed if their bank is risky, incurs losses, cuts dividends, has a high charter value, and holds high levels of subordinated debt. We only find limited evidence that forced turnovers improve bank performance.
What is "European Angst"? Is it the extension of "German Angst" to a whole continent? The latter term is often used disparagingly to describe the German tendency to problematise, weigh up and hesitate, especially when reasons for this seem slight and insignificant. But European Angst has nothing to do with stereotypical overscrupulousness. It is a mass of powerful emotions which transcend national borders and therefore seemed a fitting title for a conference which was to address disturbing developments, including populism, extremism and Euroscepticism. /// Was ist das: European Angst? Etwa die Ausweitung der German Angst auf einen ganzen Kontinent? Mit German Angst beschreibt man im Ausland oft abschätzig das Problematisieren, Abwägen und Zögern der Deutschen, besonders dann, wenn die Gründe dafür nichtig und klein erscheinen. European Angst aber hat nichts mit stereotyper Bedenkenträgerei zu tun. Sie ist vielmehr ein Bündel starker Emotionen über viele Ländergrenzen hinweg und war deshalb ein treffender Titel für eine Konferenz, auf der über beunruhigende Entwicklungen, über Populismus, Extremismus und Europaskepsis gesprochen werden sollte.
The missionaries have often been accused of having destroyed African cultures, be it deliberately or because they did not understand. The author draws a very different picture in his study of a number of German missionaries in various parts of Tanzania, who had a high appreciation of African culture. He argues that acceptance of inculturation attempts do not depend on race but on role, and the same applies to both Black and White.
Klaus W. Jonas' zweisprachige Ausgabe behandelt die literarische Laufbahn des Schriftstellers W. Somerset Maugham (1874-1965), eines der erfolgreichsten und meistgelesenen englischen Dramatiker, Essayisten und Romanciers der ersten Halfte des 20. Jahrhunderts. Maugham selbst hat das humorvolle Vorwort in der Form eines Briefes beigesteuert. Eine chronologische Darstellung seines Lebens wird erganzt durch zwei wissenschaftliche Essays des Verfassers zu Maughams umfassendem literarischen Schaffen. Von besonderem Interesse sind die Auszuge aus dem Briefwechsel zwischen Klaus W. Jonas und W. Somerset Maugham, die einen genaueren Einblick in die Personlichkeit des Schriftstellers erlauben und von der engen Vertrautheit der beiden Briefpartner zeugen. Den zweiten Teil der Ausgabe bilden eine ausfuhrliche Bibliographie von Maughams literarischem Schaffen sowie eine Auswahlbibliographie von mehr als 420 kritischen Studien in deutscher, englischer, japanischer, spanischer und franzosischer Sprache. 71 Abbildungen, viele von ihnen bisher unveroffentlicht und aus Privatbesitz, erhohen den dokumentarischen Wert dieses Bandes. In this bilingual edition the author attempts to trace the literary career of William Somerset Maugham (1874-1865), one of the most widely read and performed dramatists, essayists and novelists in English literature in the first half of the twentieth century. Maugham himself has contributed a humorous preface in the form of a letter addressed to the author. The detailed chronology of Maugham's life is being supplemented by two of the author's numerous essays dealing with the stupendous literary oeuvre of this writer. Of special interest are the excerpts from Maugham's letters to his German-born collector and biographer which provide an inside view into his personality and his friendship with Klaus W. Jonas. The second half of this volume contains a bibliographical record of Maugham's life-work and a select bibliography of 420 critical studies in German, English, French, Spanish and Japanese. 71 illustrations, many of which hitherto unpublished and privately owned, enhance the documentary value of this volume.
A monumental new biography of a pivotal yet poorly understood pioneer in modern philosophy. When a painter once told Goethe that he wanted to paint the most celebrated man of the age, Goethe directed him to Georg Wilhelm Friedrich Hegel. Hegel worked from the credo: To philosophize is to learn to live freely. While he was slow and cautious in the development of his philosophy, his intellectual growth was like an odyssey of the mind, and, contrary to popular belief, his life was full of twists and turns, suspense and even danger. In this landmark biography, the philosopher Klaus Vieweg paints a new picture of the life and work of the most important representative of German idealism. His vivid portrait provides readers an intimate account of Hegel's times and the milieu in which he developed his thought, along with detailed, clear-sighted analyses of Hegel's four major works. What results is a new interpretation of Hegel through the lens of reason and freedom. Vieweg draws on extensive archival research that has brought to light a wealth of hitherto undiscovered documents and handwritten notes relating to Hegel's work, touching on Hegel's engagement with the leading thinkers and writers of his age: Kant, Fichte, Schelling, Hölderlin, and others. Combatting clichés and misunderstandings about Hegel, Vieweg also offers a sustained defense of the philosopher's more progressive impulses. Highly praised upon its release in Germany as having set the new biographical standard, this monumental work emphasizes Hegel's relevance for today, depicting him as a vital figure in the history of philosophy.
This book, written by a prominent German political scientist and specialist for political theory and comparative government, analyses right-wing populism as a topical theme of postmodern party systems in Europe and the United States.
With more than fifty period photos and documents, countless letters and a foreword by E. D. Blodgett, F. P. Grove in Europe and Canada represents the definitive biography of the writer Northrop Frye called a "Canadian Dreiser." This work will prove an invaluable resource for scholars in Canadian and German literature, comparative literature, modernism, publishing history and translation studies."--BOOK JACKET.
In modern masonry work it is customary to use large size blocks in building. They fulfil all the construction requirements even in singlelayer outside walls. Using two houses as examples all details are presented clearly and comprehensively in a scale of 1:10. The authors elucidate on critical points, showing where care should be given to achieve convincing sustainable results.
This second of two volumes brings together invited papers of the 32nd International Wittgenstein Symposium (Kirchberg/W. (Austria), 2009). The collection not only contains articles related to some of Wittgenstein’s central arguments but also holds contributions that deal with the role and function of signs, as well as with the relations between language and action, consciousness and metaphysics. An interdisciplinary workshop was dedicated to “Wittgenstein and Literature”, an area of study which has been prominent in the philosophical discourse of the last decade. Contributors to this volume are Anat Biletzki, Michael Dummett, Laurence Goldstein, Peter Janich, Brian McGuinness, Marjorie Perloff, David Schalkwyk, Joachim Schulte, Pirmin Stekeler-Weithofer, David Stern, Eike von Savigny among others.
Employee surveys represent an established tool for many executives and HR professionals alike. However, there is often a lack of orientation when it comes to interpreting the results. What does a certain result mean? The same number can be excellent, good, aver-age, bad or even alarming. This is where this book comes in. It offers background information on all es-sential dimensions of a survey and provides concrete advice on interpretation. This makes it a valuable aid for all those who have to work practically with em-ployee survey results.
The German contribution in a famous Turkish victory at Gallipoli has been overshadowed by the Mustafa Kemal legend. The commanding presence of German General Liman von Sanders in the operations is well known. But relatively little is known about the background of German military intervention in Ottoman affairs. Klaus Wolf fills this gap as a result of extensive research in the German records and the published literature. He examines the military assistance offered by the German Empire in the years preceding 1914 and the German involvement in ensuring that the Ottomans fought on the side of the Central Powers and that they made best use of the German military and naval missions. He highlights the fundamental reforms that were required after the battering the Turks received in various Balkan wars, particularly in the Turkish Army, and the challenges that faced the members of the German missions. When the allied invasion of Gallipoli was launched, German officers became a vital part of a robust Turkish defense – be it at sea or on land, at senior command level or commanding units of infantry and artillery. In due course German aviators were to be, in effect, founding fathers of the Turkish air arm; whilst junior ranks played an important part as, for example, machine gunners. This book is not only their missing memorial but a missing link in understanding the tragedy that was Gallipoli.
A new general introduction to the Psalms. Seybold guides the reader through the most important aspects of the history and literary form of the Psalm texts and the major questions of critical scholarship, and discusses all leading writers on the subject.

The common charge laid against missionaries that they are destroyers of African culture is shown to be untrue of the missionaries treated in this book, who worked with considerable success to integrate Christianity and African culture. The author examines the endeavours of the missionaries from the perspective of the local Christians, who were not themselves interested in Africanization as such. One can thus find some missionaries defending - against the elected African Church leadership - the right of the Chagga Christians to circumcise their daughters, and Nyakyusa Christians refusing to use African tunes because the missionaries - influenced by National Socialism - professed both love for African culture and White superiority. This informative book, based on local and archival research at Daressalam University, is eminently readable. It features the first historical study of Bruno Gutmann, and provides case study material for teaching.
One of the central questions in psycholinguistics is how complex words are processed in the human mind. German ver-Verbs: Internal Word Structure and Lexical Processing explores the visual word recognition of German ver-verbs. Superficially, ver-verbs are uniform: they all begin with the sequence ver-. However, their internal structure is heterogeneous. Based on the results of various experimental designs, this book shows that the internal structure of ver-verbs is of paramount importance to their processing. Thus, the human mind employs different strategies for the processing of different types of complex words. This book is a useful companion for German, morphology, and psycholinguistics courses.
This richly illustrated hands-on guide is designed for researchers, teachers and practitioners. The huge selection of examples taken from science, basic teaching of physics, practical applications in industry and a variety of other disciplines spanning the range from medicine to volcano research allows readers to pick those that come closest to their own individual task at hand. Following a look at the fundamentals of IR thermal imaging, properties of the imaging systems, as well as basic and advanced methods, the book goes on to discuss IR imaging applications in teaching, research and industry. Specific examples include thermography of buildings, microsystems and the rather new field of IR imaging of gases. Impartially written by expert authors in the field from a renowned applied science institution, who are in the unique position of having both experience in public and private research and in teaching, this comprehensive book can be used for teaching beginners in the field as well as providing further education to specialized staff, students and researchers.
More than 80 personalities, in or from Germany, that over the centuries have shaped the development of analytical chemistry are introduced by brief biographies. These accounts go beyond summarising key biographical information and outline the individual's contributions to analytical chemistry. This richly illustrated Brief offers a unique resource of information that is not available elsewhere.
This book is about all kinds of numbers, from rationals to octonians, reals to infinitesimals. It is a story about a major thread of mathematics over thousands of years, and it answers everything from why Hamilton was obsessed with quaternions to what the prospect was for quaternionic analysis in the 19th century. It glimpses the mystery surrounding imaginary numbers in the 17th century and views some major developments of the 20th century.
Neuropsychotherapy is intended to inspire further development and continual empirical updating of consistency theory. It is essential for psychotherapists, psychotherapy researchers, clinical psychologists, psychiatrists, neuroscientists, and mental-health professionals. Profoundly important and innovative, this volume provides necessary know-how for professionals as it connects the findings of modern neuroscience to the insights of psychotherapy. Throughout the book, a new picture unfolds of the empirical grounds of effective psychotherapeutic work. Author Klaus Grawe articulates a comprehensive model of psychological functioning-consistency theory-and bridges the gap between the neurosciences and the understanding of psychological disorders and their treatment. Neuropsychotherapy illustrates that psychotherapy can be even more effective when it is grounded in a neuroscientific approach. Cutting across disciplines that are characteristically disparate, the book identifies the neural foundations of various disorders, suggests specific psychotherapeutic conclusions, and makes neuroscientific knowledge more accessible to psychotherapists. The book's discussion of consistency theory reveals the model is firmly connected to other psychological theoretical approaches, from control theory to cognitive-behavioral models to basic need theories.
The series Islamkundliche Untersuchungen was founded in 1969 by the Klaus Schwarz Verlag. Since then, it has become one of the most important venues for publications in Islamic and Middle Eastern Studies. Its more than 350 volumes cover a wide range of topics from the history, culture and societies of the Middle East and North Africa as well as neighboring regions in central, south and southeast Asia.
This second edition of a bestselling textbook offers an instructive and comprehensive overview of our current knowledge of biocatalysis and enzyme technology. The book now contains about 40% more printed content. Three chapters are completely new, while the others have been thoroughly updated, and a section with problems and solutions as well as new case studies have been added. Following an introduction to the history of enzyme applications, the text goes on to cover in depth enzyme mechanisms and kinetics, production, recovery, characterization and design by protein engineering. The authors treat a broad range of applications of soluble and immobilized biocatalysts, including wholecell systems, the use of non-aqueous reaction systems, applications in organic synthesis, bioreactor design and reaction engineering. Methods to estimate the sustainability, important internet resources and their evaluation, and legislation concerning the use of biocatalysts are also covered.
This book adds in chapter 1 and 2 the MIN-key techniques Laser and sealing, completing the 3 MIN-key techniques of the first volume. In chapter 3 the evolution of anatomy to a key-concept of MIN is described, presenting theory and reality of anatomical perspectives that can be used by the MIN-surgeon directly in the OR. Anatomy must be elaborated according to Gestalt-Theory to become a Key of MIN. Still anatomy is the "House of Medicine”, giving a mental place to all knowledge, theories and biological functions. The "surgical simulation concept" of chapter 4 as trainings environment follows, also as a key-concept of MIN. In this chapter we draw the line from Gestalt-Anatomy to a Surgical Simulation Application in Pathological Anatomy exemplified in aneurysm cases. Chapter 5 presents the best preservation technique of anatomical perishable matter, forming durable, dry and odorless specimen of unknown precision and beauty. The scientific value of this unique technique and the benefit for MIN are shown by many examples.With the Plastination gallery of chapter 6 the best head-plastinates and sheet-plastinates of head and brain complete the volume. Many of the specimen have been shown around the globe in the famous exhibitions “body worlds“ (Prof. Dr. G. v. Hagens/Inventor of Plastination).

Royal and princely courts in the late Middle Ages and Early Modern period did not only fill the roles of centers of government. The striving for a synthesis between power and the mind made courts into sites of art and literature, of instruction and education. Sons of nobles learned at court not only the use of weapons, but also reading, writing and arithmetic. Jousting gave young knights the opportunity to test their weapons skills and horsemanship. Moreover festivities were a part of court life, and feasts were celebrated extravagantly. Those nobles who lived as knights as well as the academically educated bourgeois used royal and princely courts as opportunities for assuring their professional careers and for social advancement. The reality of the social and ruling fabric of the court included in the late Middle Ages and Early Modern period some rough criticism from those eloquent contemporaries who branded the court as a morally corrupt place of vices. Church reformers brought the courtly lifestyle and the Christian ethic into irreconcilable contrast. How Enea Silvio Piccolimini, the humanist occupying the seat of St. Peter in Rome, and Ulrich von Hutten, the knightly poet, perceived, criticized and justified courtly life, is the subject of this book.
Software product lines represent perhaps the most exciting paradigm shift in software development since the advent of high-level programming languages. Nowhere else in software engineering have we seen such breathtaking improvements in cost, quality, time to market, and developer productivity, often registering in the order-of-magnitude range. Here, the authors combine academic research results with real-world industrial experiences, thus presenting a broad view on product line engineering so that both managers and technical specialists will benefit from exposure to this work. They capture the wealth of knowledge that eight companies have gathered during the introduction of the software product line engineering approach in their daily practice.
Prosody is generally studied at a separate linguistic level from syntax and semantics. It analyses phonetic properties of utterances such as pitch and prominence, and orders them into phonological categories such as pitch accent, boundary tone, and metrical grid. The goal is to define distinctive formal differentiators of meanings in utterances. But what these meanings are is either excluded or a secondary concern. This book takes the opposite approach, asking what are the basic categories of meaning that speakers want to transmit to listeners? And what formal means do they use to achieve it? It places linguistic form in functions of speech communication, and takes into account all the formal exponents - sounds, words, syntax, prosodies - for specific functional coding. Basic communicative functions such as 'questioning' may be universally assumed, but their coding by linguistic bundles varies between languages. A comparison of function-form systems in English, German and Mandarin Chinese shows this formal diversity for universal functions.
Highly acclaimed and considered the leading reference in the field, Pathology of Melanocytic Nevi and Malignant Melanoma has now been fully revised and updated to accomodate rapid advances in the field of melanoma pathology. Drs. Michael Piepkorn and Klaus Busam have now joined Dr. Barnhill, world-renowned expert in dermatology and pathology, to expand the text with new sections on the genetics and cytogenetics of melanoma, sentinal lymph node biopsy, the new AJCC TNM staging system for melanoma, the mechanisms of melanoma metastasis. The successful focus and format of the first edition have been preserved. Each lesion and diagnosis is clearly illustrated, now with more than 340 new, digitally enhanced full-color photomicrographs and over 125 tables. A corresponding precis, or concise description of the clinical features, histopathology, differential diagnosis, and outstanding characteristics of each lesion provides readers with a quick yet comprehensive overview of each topic covered. With the inclusion of recent advances in cancer research and new techniques, the second edition of Pathology of Melanocytic Nevi and Malignant Melanoma is the essential reference for every practicing dermatopathologist, pathologist, dermatologist, and cancer research scientist today.
Stroke MRI is a new imaging tool providing detailed information of the pathophysiological aspects of cerebral ischemia. This book with CD-ROM includes a case collection of 25 hyperacute stroke patients, all imaged within six hours of stroke onset with a complete stroke MRI protocol. Stroke MRI and the established clinical methods are compared and recent results from single and multicenter trials are presented to demonstrate the advantages of MRI for stroke patients. The CD-ROM contains diffusion-, T2-, T2*-perfusion-weighted images and MR angiography. Each case offers to answer the relevant questions concerning vessel status and lesion size as well as presence or absence of a "tissue at risk" with a self assessment mode and the expertsa (TM) therapeutic decision. The CD and the book are complementary to avoid redundancy as far as possible. They will be useful to both the experienced researcher using MRI and the clinician or researcher with no previous knowledge of the technology.
today, the name RKW Architektur + Städtebau evokes two hundred architects whose work never fails to convince. The reason does not lie in the narrowly defined architectural language of individual leaders of the firm. More than in any other firm, the various teams are given generous latitude for independent initiative. Thus, this documentation of the last ten years, with cross - references to the development of this unique partnership since 1950, doesn’t just present sixty - five structures and projects from an internationally sought - after firm. On the contrary, in its search for the secret of the firm’s success, it looks behind the scenes in numerous interviews and essays. The works considered range from the research facilities for AUDI, the new sciences campus of RWTH Aachen University, and the corporate headquarters of Vodafone, Debitel, and Arag to urban revitalization projects, residential buildings, schools, sports halls, railroad stations, city halls, banks, urban office buildings and shopping centers, and the stadium for the 2012 European Soccer Championship in Gdansk.
Ever since the boom of spectrum analysis in the 1860s, spectroscopy has become one of the most fruitful research technologies in analytic chemistry, physics, astronomy, and other sciences. This book is the first in-depth study of the ways in which various types of spectra, especially the sun's Fraunhofer lines, have been recorded, displayed, and interpreted. The book assesses the virtues and pitfalls of various types of depictions, including hand sketches, woodcuts, engravings, lithographs and, from the late 1870s onwards, photomechanical reproductions. The material of a 19th-century engraver or lithographer, the daily research practice of a spectroscopist in the laboratory, or a student's use of spectrum posters in the classroom, all are looked at and documented here. For pioneers of photography such as John Herschel or Hermann Wilhelm Vogel, the spectrum even served as a prime test object for gauging the color sensitivity of their processes. This is a broad, contextual portrayal of the visual culture of spectroscopy in the 19th and early 20th centuries. The illustrations are not confined to spectra--they show instruments, laboratories, people at work, and plates of printing manuals. The result is a multifacetted description, focusing on the period from Fraunhofer up to the beginning of Bohr's quantum theory. A great deal of new and fascinating material from two dozen archives has been included. A must for anyone interested in the history of modern science or in research practice using visual representations.
