The Jews: A History is a comprehensive and accessible text that explores the religious, cultural, social, and economic diversity of the Jewish people and their faith. Placing Jewish history within its wider cultural context, the book covers a broad time span, stretching from ancient Israel to the modern day. It examines Jewish history across a range of settings, including the ancient Near East, the age of Greek and Roman rule, the medieval realms of Christianity and Islam, modern Europe, including the World Wars and the Holocaust, and contemporary America and Israel, covering a variety of topics, such as legal emancipation, acculturation, and religious innovation. The third edition is fully updated to include more case studies and to encompass recent events in Jewish history, as well as religion, social life, economics, culture, and gender. Supported by case studies, online references, further reading, maps, and illustrations, The Jews: A History provides students with a comprehensive and wide-ranging grounding in Jewish history.
Imperial Pomp - Post-Soviet High-Rise Frank Herfort travelled all over Russia for a photographic project that lasted several years, following the ideas of architectural photography and taking pictures of skyscrapers that had been quickly built after the collapse of the Soviet Union. The force and magnitude of these buildings appears bizarre, pompous and exotic; equally they evoke larger-than-life Soviet memorials. They express a longing for lost greatness and the ambition to go one better. Contextual contradictions however add another completely different grace note: the Russian residential buildings and faded idylls around the new constructions introduce a second level of meaning to the images, which poses questions and raises enigmas. Nostalgia for Past Grandeur In documenting a unique phenomenon, the German photographer Frank Herfort has journeyed to the most remote areas of the former Soviet Union. After the collapse of the regime, a strangely pompous architectural style sprung up throughout the new republic. It conflates the aesthetics of monumental Soviet architecture with the Western language of form seen in the twentieth century.
The third edition of this successful textbook is a comprehensive, rigorous survey of the major topics in the field of behavioral economics. Building on the strengths of the second edition, it offers an up-to-date and critical examination of the latest literature, research, developments and debates in the field. Offering an inter-disciplinary approach, the authors incorporate psychology, evolutionary biology and neuroscience into the discussions. And, ultimately, they consider what it means to be 'rational', why we so often indulge in 'irrational' and self-harming behavior, and also why 'irrational' behavior can sometimes serve us well. A perfect book for economics students studying behavioural economics at higher undergraduate level or Master's level. This new edition features: - Extended material on heuristics and biases, and new material on neuroeconomics and its applications - A wealth of new topical case studies, such as voting behavior in Brexit and the Trump election and the current obesity epidemic - More examples and review questions to help cement understanding

An illuminating investigation into why some parties evolve with their times while others fall behind. Around the world, established political parties face mounting pressures: insurgents on the Left and Right, altered media environments, new policy challenges, and the erosion of traditional strongholds, to name just a few. Yet parties have differed enormously in their ability to move with the times and update their offers to voters. This variation matters. While adaptation does not guarantee a party’s electoral success, the failure to modernize can spell its decline, even collapse, and create openings for radical and populist parties that may threaten the future of liberal democracy. Parties under Pressure examines why some parties adapt meaningfully to social, economic, and political transformations while others flounder, focusing especially on the fate of Western Europe’s Christian democratic parties. Matthias Dilling reveals the under-appreciated importance of party factions. While very high levels of factionalism are counter-productive and create paralysis, more moderate levels of factionalism help parties to adapt by giving visibility to fresh groups and ideas. Dilling draws on extensive archival research in Germany, Italy, and Austria, as well as evidence from France, Japan, and beyond. Taking a comparative-historical approach, Parties under Pressure sheds new light on parties’ varying records of adaptive reforms over more than seventy-five years.
Stalin had never been able to shake off the nightmare of Adolf Hitler. Just as in 1941 he refused to understand that Hitler had broken their non-aggression pact, he was in 1945 unwilling to believe that the dictator had committed suicide in the debris of the Berlin bunker. In his paranoia, Stalin ordered his secret police, the NKVD, precursor to the KGB, to explore in detail every last vestige of the private life of the only man he considered a worthy opponent, and to clarify beyond doubt the circumstances of his death. For months two captives of the Soviet Army -- Otto Guensche, Hitler's adjutant, and Heinz Linge, his personal valet--were interrogated daily, their stories crosschecked, until the NKVD were convinced that they had the fullest possible account of the life of the Fü In 1949 they presented their work, in a single copy, to Stalin. It is as remarkable for the depth of its insight into Adolf Hitler -- from his specific directions to Linge as to how his body was to be burned, to his sense of humor -- as for what it does not say, reflecting the prejudices of the intended reader: Joseph Stalin. Nowhere, for instance, does the dossier criticize Hitler's treatment of the Jews. Today, the 413-page original of Stalin's personal biography of Hitler is a Kremlin treasure and it is said to be held in President Putin's safe. The only other copy, made by order of Stalin's successor, Nikita Khrushchev, in 1959, was deposited in Moscow Party archives under the code number 462A. It was there that Henrik Eberle and Matthias Uhl, two German historians, found it. Available to the public in full for the first time, The Hitler Book presents a captivating, astonishing, and deeply revealing portrait of Hitler, Stalin, and the mutual antagonism of these two dictators, who between them wrought devastation on the European continent.
The book remains a valuable tool both for statisticians who are already familiar with the theory of copulas and just need to develop sampling algorithms, and for practitioners who want to learn copulas and implement the simulation techniques needed to exploit the potential of copulas in applications.'Mathematical ReviewsThe book provides the background on simulating copulas and multivariate distributions in general. It unifies the scattered literature on the simulation of various families of copulas (elliptical, Archimedean, Marshall-Olkin type, etc.) as well as on different construction principles (factor models, pair-copula construction, etc.). The book is self-contained and unified in presentation and can be used as a textbook for graduate and advanced undergraduate students with a firm background in stochastics. Besides the theoretical foundation, ready-to-implement algorithms and many examples make the book a valuable tool for anyone who is applying the methodology.
Business process modelling is referred to as a complex, time consuming, and error prone task. The correction and improvement of badly designed process models becomes increasingly expensive in the later phases of the process management life cycle. This thesis develops the principles of guided process modelling and provides a contribution towards simplifying process modelling activities. The general research question this thesis answers is what are the difficulties in the usage of process modelling tools and which methods, techniques, and tools can guide users in modelling processes to target the existing problems. The question is addressed by following a research methodology of design sciences. Amongst others, it includes a detailed analysis of the research problem, a definition of the objective, the design and development of solutions, and an evaluation of the developed concepts. In summary, the thesis presents innovative concepts to support modellers and provides a step towards end-user enablement in process modelling.
A memorable History of Cliffside Park, NJ, thoroughly assembled and written by Lawrence (Larry) Matthias, the key contributor to the History Room at the Cliffside Park Free Public Library and a devoted volunteer with the Friends of the Library.
The book provides readers with an overview of the unique features of German business and enterprise law and an in-depth analysis of the organs of governance of German public limited companies (general meeting, management board, supervisory board). In addition, approaches for reforms required at the international level are also suggested and discussed, including, among others, the unique interplay and dynamics of the German two-tier board model with the system of codetermination, referring to the arrangement of employees sitting on the supervisory boards of German public limited companies and private companies employing more than 500 employees; also covered are significant recent legal developments in Europe.The book highlights the core function of valuation and financial reporting at the international, European and German levels, with accounting as the documentary proof of good corporate governance. Corporate governance encompasses the free enterprise system, which is treated comprehensively in this book from a German perspective. This distinguishes the book from other books written in English in this subject area, not only because of the comprehensive way it covers German corporate law and corporate governance, but also because of the fact that it provides international and European perspectives on these important topics.The book is addressed to researchers, practitioners and basically anyone with an interest in the complex, but intriguing areas of corporate law and corporate governance.
The Egyptian language, with its written documentation spreading from the Early Bronze Age (Ancient Egyptian) to Christian times (Coptic), has rarely been the object of typological studies, grammatical analysis mainly serving philological purposes. This volume offers now a detailed analysis and a diachronic discussion of the non-verbal patterns of the Egyptian language, from the Pyramid Texts (Earlier Egyptian) to Coptic (Later Egyptian), based on an extensive use of data, especially for later phases. By providing a narrative contextualisation and a linguistic glossing of all examples, it addresses the needs not only of students of Egyptian and Coptic, but also of a linguistic readership. After an introduction into the basic typological features of Egyptian, the main book chapters address morphology, syntax, semantics and pragmatics of the three non-verbal sentence types documented throughout the history of this language: the adverbial sentence, the nominal sentence and the adjectival sentence. These patterns also appear in a variety of clausal environments and can be embedded in verbal constructions. This book provides an ideal introduction into the study of Egyptian historical grammar and an indispensable companion for philological reading.
Defining Management charts the expansion of management as an idea and practice from a time when it was limited to churches and households to its current ubiquity, focusing in particular on the role of business schools, consultants, and business media in this process. How did an entire industry develop around business schools, consultants, and business media who are now widely considered the authorities regarding best management practice? This book shows how these actors – on their own and in interaction – became taken-for-granted and gained such definitional power over management and managers, expanded across the globe from often modest and not always respected origins, and impacted, and continue to impact businesses and, increasingly, the broader economic and social context. Building on extant and some new research, the book is unique in bringing together issues and actors that have been examined elsewhere separately. Any student or professional of management interested in the evolution of their field or the rise of business schools, consultants and business media will find this book both novel and thought-provoking.

An invaluable resource for students of law, politics, international relations and technology as well as for diplomats and civil society actors, this publication demonstrates how the Council of Europe contributes to ensuring that everyone’s voice online can be heard. This is key to sustainable, human rights oriented and people-centred digitalisation. Human rights matter on the internet. Without freedom of expression, people cannot participate in everything that the information society has to offer. Yet online free speech is in danger. Between state laws, private rules and algorithms, full participation in the online communicative space faces many challenges. This publication explores the profound impact of the internet on free expression and how it can be effectively secured online. The second, updated edition of this introduction into the protection of freedom of expression online answers essential questions regarding the extent and limits of freedom of expression online and the role of social networks, courts, states and organisations in online communication spaces. In clear language, with vivid examples spanning two decades of internet law, the authors answer questions on freedom of expression in cyberspace. Addressing issues from the protection of bloggers to the right to access online information, the publication also shows the importance of the standard-setting, monitoring and promotion activities of international and non-governmental organisations and includes a chapter on relevant national practice. It pays special attention to the role of European human rights law and the Council of Europe as this region’s most important human rights organisation.
There is a gap in the existing literature as to why the New Left in West Germany entered a phase of rapid decline by the end of the 1070s. The overarching aim of this thesis is to offer a politico-theoretical explanation for the historical development of the New Left and why the 'red decade' between 1967 and 1976/77 ended so abruptly. Within this context, the thesis will focus on the Maoist K-Gruppen and particular emphasis will be placed on the Marxistische Gruppe., which defied the general decline of West Germany's New Left and developed into its largest organisation during the 1980s. Furthermore, the Red Cells movement will be analysed from which both currents emerged in the wake of the student movement. In conclusion, this thesis will reveal that the influence of politico-theoretical aspects on the historical development of the New Left has been given too little consideration and that the New Left's fate cannot be adequately explained by external factors, but demands the consideration of the very development of theories and the practical conclusions organisations reached regarding their social, economic and cultural circumstances. This work will be the first to provide an insight into the potential of such a theoretical explanation for an understanding of the specific developments of the post-1968 West German New Left.
First-hand account of the current state of addiction governance in Europe, utilising a unique dataset of corporate memberships and networks across the EU to document the overall architecture of corporate political activity and the role addictive substance and behaviour-producing industries play in influencing addiction policy in Europe.
This study of Joseph Conrad's influential work "Heart of Darkness" presents for the first time the German-language reception of this reference text in the debate on postcolonialism. The spectrum ranges from Conrad's contemporaries (like Kafka) to many canonical authors of the 20th century (including Thomas Mann, Ernst Jünger, Christa Wolf) to the most recent names in literature (i.e. Christian Kracht und Lukas Bärfuss). Beyond the readings of their works, the study contributes to the study of cultural transfers as well as to Conrad philology, and it expands the theory of intertextuality with parameters that capture the complex factor of power in postcolonial relations.
There is order on the internet, but how has this order emerged and what challenges will threaten and shape its future? This study shows how a legitimate order of norms has emerged online, through both national and international legal systems. It establishes the emergence of a normative order of the internet, an order which explains and justifies processes of online rule and regulation. This order integrates norms at three different levels (regional, national, international), of two types (privately and publicly authored), and of different character (from ius cogens to technical standards). Matthias C. Kettemann assesses their internal coherence, their consonance with other order norms and their consistency with the order's finality. The normative order of the internet is based on and produces a liquefied system characterized by self-learning normativity. In light of the importance of the socio-communicative online space, this is a book for anyone interested in understanding the contemporary development of the internet. This is an open access title available under the terms of a CC BY-NC-ND 4.0 International licence. It is offered as a free PDF download from OUP and selected open access locations.

Eine Übersicht für Architekten, die auch die Bedeutung der Baustoffwahl für die sinnliche Wahrnehmung von Architektur wie Haptik, Geruch, Farbe, Oberflächenstruktur berücksichtigt, gab es bisher nicht. Mit dem Baustoff Atlas wird diese Lücke nun geschlossen. Als ein auf die Interessen von Architekten und Bauingenieuren gleichermassen abgestimmtes Grundlagenwerk wird er alle genannten Betrachtungsebenen vereinen. Dabei werden sowohl grundsätzliche Nachhaltigkeitsfragen wie Lebensdauer, Umweltbelastung und Stoffkreisläufe erörtert als auch Materialinnovationen vorgestellt. Alle wesentlichen herkömmlichen und neuartigen Baustoffe werden hinsichtlich Herstellung, Verarbeitung, Oberflächen, Anschlüssen und Kenndaten umfassend dokumentiert. Internationale Beispiele, deren Erscheinungsbild sich häufig aus jeweils einem Material definiert, veranschaulichen die Anwendung in der Architektur. Der Baustoff Atlas unterstützt damit die tägliche Arbeit von Architekten und Ingenieuren bei der Baustoffauswahl auf eine umfassende, zugleich anschauliche und anregende Weise.
This book challenges the idea that Western media systems are becoming more American in the digital age, arguing that journalistic cultures are not only significantly different from each other still but also variably open and resistant to change. Drawing upon extensive field research of political reporters and examination of discourses of journalistic professionalism as well institutional analysis, this book finds that occupational norms and values of journalism in the US are vigorously upheld but in fact relatively porous and malleable. In Germany, by contrast, professional boundaries are rather strong and resilient but treated matter-of-factly. Revers argues that this is both a consequence of institutional arrangements of media systems and historically evolved cultural principles of journalism in both countries which mutually constitute each other.
On February 27, 1973, a group of roughly 300 armed Indigenous men, women, and children seized the tiny hamlet of Wounded Knee, South Dakota, at gunpoint, took hostages, barricaded themselves in the hilltop church, and raised an upside-down American flag. Taking place at the site of the infamous massacre in 1890, the highly symbolic confrontation spearheaded by the American Indian Movement (AIM) ultimately evolved into a prolonged, seventy-one-day armed standoff between law enforcement officers and modern-day Indigenous warriors. Among these warriors were Vietnam War veterans armed with Vietnam-era equipment and weaponry. By organizing in defense of the newly proclaimed Independent Oglala Nation, the AIM activists at Wounded Knee linked their nationalist quest for sovereignty and self-determination with a warrior masculinity they constructed from a mix of Indigenous cultures and contemporary cultural elements, including the Black civil rights movement, the counterculture of the 1960s and early 1970s, and the antiwar movement. As Matthias André Voigt shows, the takeover of Wounded Knee was only one moment among many in the complex interplay between protest activism, gender, race, and identity within AIM. While AIM is widely recognized for its militancy and nationalism, Reinventing the Warrior is the first major study to examine the gendered transformation of Indigenous men within the Red Power movement and the United States more generally. AIM activists came to regard themselves, like their ancestors before them, as warriors fighting for their people, their lands, and their rights. They sought to remasculinize their Indigenous identity in order to confront hegemonic masculinities—and, by implication, colonialism itself. By becoming “more manly,” Indigenous men challenged the disempowering nature of white supremacy. Voigt traces the story of the reinvention of Indigenous warriorhood from 1968 to the takeover of Wounded Knee in 1973 and beyond. His trailblazing work explores why and how Indigenous men refashioned themselves as modern-day warriors in their anticolonial nation-building endeavor, thereby remaking both self and society.
Jewish Wayfarers in Modern China focuses on the many extraordinary contacts between East and West in China during the 20th century. Through a collection of short biographies situated in the context of Chinese and Western history, it offers a panoramic view of China as experienced by many different persons of Jewish origins during their sojourn in the Middle Kingdom. The book offers a journey across vast reaches of space and back through time. Our impressions of visits to China have often been biased by sensational journalism, Hollywood films and literary entertainment that have distorted the reality of this vast country. Jewish Wayfarers in Modern China offers the reality of life in twentieth century China through the carefully-researched biographies of a variety of typical and less typical Western visitors to the Middle Kingdom.
Drawing on previously inaccessible and overlooked archival sources, The Herero Genocide undertakes a groundbreaking investigation into the war between colonizer and colonized in what was formerly German South-West Africa and is today the nation of Namibia. In addition to its eye-opening depictions of the starvation, disease, mass captivity, and other atrocities suffered by the Herero, it reaches surprising conclusions about the nature of imperial dominion, showing how the colonial state’s genocidal posture arose from its own inherent weakness and military failures. The result is an indispensable account of a genocide that has been neglected for too long.
Poly(ethylene terephthalate) is one of the most widely used polymers in packaging industry, due to its high mechanical strength, chemical resistance, and barrier functions. However, its processing is determined by degradation and low viscosity. In particular, foaming and film blowing is restricted by the linear structure of the molecule and low melt strength. The stability of three linear commercial PET grades produced by different synthesis routes with different molar masses is analyzed in regards of processing at industrial scale. Subsequently, reactive processing with three multi-functional chain extenders (pyromellitic dianhydride, PMDA, tetraglycidyl diamino diphenyl methane, TGDDM, and triphenyl phosphite, TPP) is conducted to create large and long-chain branched (LCB) molecules. The mechanical and molecular properties in melt state are analyzed by linear and non-linear viscoelastic rheology, modeling by the molecular stress function (MSF) theory and size-exclusion chromatography (SEC) with light scattering measurements. Thermal stability measurements in the linear viscoelastic regime revealed degradation and a reduction of the storage modulus in air atmosphere, and, besides thermal degradation, an enhancement of the modulus in nitrogen atmosphere, due to polycondensation [Kruse et al., 2013]. Fitting by an exponential function leads to the reconstruction of the initial state of the sample at zero-loading time and to a time constant, which reveals clear relations between stability and molar mass for all three PET grades in both atmospheres. High molar mass PET is more stable in nitrogen and less stable in air environment, and vice versa, depending on OH end group concentration and synthesis route. The analysis by means of time-resolved mechanical spectroscopy allows the observations of moduli and complex viscosity at a fixed time, a wide range of angular frequencies, and at different atmospheres, and revealed: (i) a plasticizer effect induced by small molecules from thermal and thermo-oxidative degradation, (ii) cross-linking leading to yield stress, (iii) diffusion influencing polycondensation reaction, (iv) slipping due to deposition of side products, and (v) an enhanced shear thinning regime [Kruse and Wagner, 2016]. The extrusion of neat PET with a twin-screw extruder at industrial scale leads to strong reduction of viscosity mainly due to shearing. The impact of thermo-oxidative degradation is comparably small. The reactive processing of the three PET grades with the three chain extenders leads to the conclusion that the tri-functional TPP is not a useful chain extender due to rapid degradation and toxicity. The two tetra-functional chain extenders, PMDA and the epoxy-based TGDDM, lead to strong viscosity increase, increasing strain hardening effect, and increasing thermal stability with increasing chain extender concentration as confirmed by loss- and storage modulus, phase angle, activation energy of flow, and elongational viscosity. The MSF model predictions show good agreement with data measured, and allowed a quantitative analysis of the branching structure and of the stretch of the molecules by both non-linear MSF parameters. In comparison to the high molar mass PET with an apparent comb-like structure at high PMDA concentrations, the two initially low molar mass grades show a higher molar mass after processing with PMDA and seem to have a tree-like structure, which can be explained by the hydroxyl end group concentration of these two PET grades. The extensive use of TGDDM leads to a hyperbranched and gel-like structure. The fracture analysis from uniaxial elongation experiments reveals a limiting stress value for high PMDA concentrations and a limiting strain value for high TGDDM concentrations due to formation of a covalent network. The molecular analysis by SEC with triple detection of the high molar mass PET, which was reacted with PMDA and TGDDM, shows a strong increase of the average molar masses, polydispersity, radius of gyration, and hydrodynamic radius and confirms the molar mass increase observed by the rheological measurements. The branching was confirmed by a decreasing Mark-Houwink exponent with increasing chain extender concentration. Further, the analysis of the contraction of the molecule revealed a more star-like structure at low concentrations for both chain extenders. With increasing concentration, the structure changed to more comb-like for PMDA and random tree-like or hyperbranched for TGDDM as was also observed by non-linear viscoelastic measurements. PMDA revealed to be an excellent coupling agent which induces reproducibly either a star-like, comb-like, or tree-like structures depending on the concentration of coupling agent added and the hydroxyl concentration of the PET employed. Polyethylenterephthalat (PET) zeichnet sich durch hervorragende mechanische Eigenschaften, sowie chemische Beständigkeit und Barriereeigenschaften aus und findet insbesondere in der Verpackungsindustrie Verwendung. Die Neigung zur Degradation und die wegen der linearen Kettenmoleküle geringe Viskosität schränken jedoch die Verarbeitbarkeit von PET wie beispielsweise das Schäumen und Folienblasen erheblich ein. In der vorliegenden Arbeit wird der Einfluss der thermischen Stabilität während der Verarbeitung von drei linearen industriellen PET-Typen untersucht, die sich durch Molmasse und Herstellungsverfahren unterscheiden. Des Weiteren wird langkettenverzweigtes PET (LCBPET) durch reaktive Verarbeitung mit drei verschiedenen multifunktionalen Kettenverlängerern, Pyromellitsäuredianhydrid (PMDA), Tetra- glycidyl-Diamino-Diphenyl-Methan (TGDDM) und Triphenylphosphit (TPP), hergestellt und charakterisiert. Durch die experimentelle Bestimmung der linearen und nichtlinearen rheologischen Eigenschaften der Schmelze und ihre Beschreibung mit Hilfe des sogenannten "Molecular Stress Function" (MSF) Modells gelingt eine quantitative Analyse des Materialverhaltens. Die molekulare Analyse wird zusätzlich durch die Ergebnisse von Gelpermeationschromatographie (GPC bzw. SEC) in Verbindung mit Lichtstreumessung gestützt. Die Untersuchungen der thermischen Stabilität von linearem PET im linear-viskoelastischen Bereich zeigen einen abnehmenden Speichermodul und somit ein thermo-oxidatives Degradationsverhalten in Luftatmosphäre. In inerter Stickstoffatmosphäre tritt hingegen nur thermische Degradation auf, gleichzeitig führt jedoch eine Polykondensationsreaktion zu einem Anstiegen des Moduls [Kruse et al., 2013]. Mit einem exponentiellen Regressionsansatz kann der anfängliche Zustand des Moduls in beiden Atmosphären zum Zeitpunkt Null, der dem Einbringen der Probe in das Rheometer entspricht, rekonstruiert werden. Die sich aus diesem Ansatz ergebende Zeitkonstante erlaubt es, quantitative Zusammenhänge zwischen der thermischen Stabilität der drei PET-Sorten und deren Molmasse sowie dem Herstellungsverfahren der PET-Typen aufzuzeigen. So weist hochmolekulares PET eine höhere Stabilität in Stickstoff und eine geringere Stabilität in Luft auf und umgekehrt. Hauptursache für dieses Verhalten ist die unterschiedliche Konzentration an Hydroxylendgruppen, die je nach Molmasse und Herstellungsmethode der jeweiligen PET-Typen variiert. Mit Hilfe der "Time-Resolved Mechnical Sprectroscopy" konnte die sich ändernde Viskosität über ein weites Frequenzspektrum und zu einer beliebigen Messzeit in beiden Atmosphären bestimmt werden. Wesentliche Ergebnisse dieser Untersuchung sind der Nachweis des Auftretens von (i) einem Weichmachereffekt bedingt durch die thermische und thermo-oxidative Degradation und den daraus resultierenden Oligomeren, (ii) dreidimensionaler Vernetzung mit der Ausbildung einer Fließgrenze, (iii) Diffusionsprozessen, die Einfluss auf die Polykondensationsreaktion haben, (iv) Wandgleiten, bedingt durch die Ablagerung von Nebenprodukten auf den Platten des Rheometers und (v) einem verbreiterten Scherverdünnungbereich [Kruse and Wagner, 2016]. Die Extrusion von linearem PET mit einem Doppelschneckenextruder unter industriellen Bedingungen führt zu einer starken Abnahme der Viskosität, die hauptsächlich durch Scherung und weniger durch thermo-oxidativen Abbau verursacht wird. Bei der reaktiven Verarbeitung der drei PET-Typen mit den drei verschiedenen Kettenverlängerern erwies sich das dreifunktionale TPP auf Grund von Toxizität und Lagerinstabilitäten als unbrauchbar. Die Verarbeitung der beiden vierfunktionalen Kettenverlängerer, PMDA und das epoxidhaltige TGDDM, führt zu erhöhter Viskosität, erhöhter Dehnverfestigung und erhöhter thermischer Stabilität mit zunehmender Konzentration des jeweiligen Kettenverlängerers. Das beschriebene Verhalten zeigt sich sowohl am Speicher- und Verlustmodul und dem daraus abgeleiteten Verlustwinkel, als auch an der Fließaktivierungsenergie und der Dehnviskosität. Dabei lassen sich die gemessenen Dehnviskositäten sehr präzise mit dem MSF-Modell beschreiben und die beiden nichtlinearen Modelparameter, β und f_max^2 ermöglichen eine quantitative Analyse der Verzweigungsstruktur und der Molekülstreckung. So zeigt die Modifiziereng von hohen PMDA-Konzentrationen und dem hochmolekularen PET eine mehr kammartige Struktur im Vergleich zu den beiden niedermolekularen PET-Typen, die eine baumartige Molekülstruktur und eine höhere Molmasse nach der reaktiven Extrusion aufweisen. Beide Effekte können mit der höheren OH-Endgruppenkonzentration der beiden niedermolekularen PET-Typen erklärt werden. Zu hohe Zusätze von TGDDM führen zu einem hochverzweigten und gelartigen Polymer. Das Bruchverhalten bei der uniaxialen Dehnung von mit einem hohen Zusatz von PMDA hergestellten langkettenverzweigten PET wird von einer limitierenden Bruchspannung bestimmt. Demgegenüber bestimmt eine maximale Dehnung das Bruchverhalten des mit einem hohen TGDDM-Zusatz hergestellten LCB-PET, verursacht durch ein kovalent gebundenes Polymernetzwerk. Die GPC Messungen mit drei Detektoren wurden an LCB-PET durchgeführt, das auf Basis der hochmolekularen PET-Type hergestellt wurde. Die molekulare Analyse der mit PMDA und TGDDM modifizierten Proben zeigt eine deutliche Zunahme der mittleren Molmassen, Molmassenverteilungsbreite, des Gyrationsradius und des hydrodynamischen Radius und bestätigt somit die rheologischen Ergebnisse. Das Auftreten von Verzweigungen wird außerdem durch den abnehmenden Mark-Houwink-Exponenten bei zunehmender Additivkonzentration verdeutlicht. Eine genauere Betrachtung weist auf eine sternartige Molekülstruktur bei geringer Zugabe beider Kettenverlängerer hin. Bei erhöhter Zugabe hingegen tritt eine kammartige Struktur bei PMDA und eine baumartige oder hochverzweigte Struktur bei TGDDM auf, wie auch aus den nichtlinearen viskoelastischen Messungen zu schließen ist. Insbesondere PMDA erweist sich als hervorragender Kettenverlängerer, der bei reaktiver Extrusion reproduzierbar eine sternartige, kammartige oder baumartige Molekülstruktur in Abhängigkeit von der verwendeten PET-Type und der PMDA-Konzentration ermöglicht und so das Verarbeitungsspektrum von PET auf neue Anwendungsgebiete erweitert.
The present doctoral dissertation contributes to the analysis of glass panels subjected to blast load, concentrating on monolithic and laminated glass prior to glass fracture. A straightforward graphical solution for monolithic glass is presented to identify maximum deformation and maximum principal stress for small and large deformations for static and idealized blast load without software. On the basis of experimental tests, load duration factors kmod for impact and blast load design for annealed glass, heat strengthened glass and fully tempered glass are proposed. In addition, design strength values for impact and blast design based on the European and German standards are suggested. As a result, blast pressure capacity charts for monolithic fully tempered glass plates subjected to idealized blast load are presented. Moreover, design temperatures of interlayer in blast design situation based on empirical data in accordance with Eurocode are determined for vertical double glazed and triple glazed units for Germany, showing that laminated glass should not be regarded with monolithic glass approach in general.
Environmental Economics explores the ways in which economic theory and its applications, as practised and taught today, must be modified to explicitly accommodate the goal of sustainability and the vital role played by environmental capital. Pivoting around the first and second laws of thermodynamics, as well as the principles of ecological resilience, this book is divided into five key parts, which include extensive coverage of environmental microeconomics and macroeconomics. It drills down into issues and challenges including consumer demand; production and supply; market organisation; renewable and non-renewable resources; environmental valuation; macroeconomic stabilisation and international trade and globalisation. Drawing on case studies from forestry, water, soil, air quality and mining, this book will equip readers with skills that enable the analyses of environmental and economic policy issues with a specific focus on the sustainability of the economy. This new edition has been updated throughout and provides further coverage on topics such as energy transition, market organisation and the role of environmental economics in regulatory decision-making including critiques of contemporary policy directives like tradable pollution permits and net zero emissions. Challenges to achieving stabilisation and emission reduction have been expanded to include wars and conflicts such as those in the Middle East and the Russian invasion of Ukraine. This book further reinforces the premise that there are clear limits to growth and that modesty and moderation are superior alternatives. Rich in pedagogical features, including key concept boxes and review questions at the end of each chapter, this book will be a vital resource for upper-level undergraduate and postgraduate students studying not only environmental economics/ecological economics but also economics in general.
A three-part investigation on the origins and evolving roles that Islamic law and international humanitarian law have played in regulating conflict and violence, War and Law in the Islamic World brings to light legal and policy complexities that plague modern-day armed conflict in the region.

Further options, possibilities, and limits for applications are given. Techniques for the characterization of thin films are addressed as well.
A significant amount of German and French career agents are involved with international careers. Applying Bourdieu’s Theory of Practice, Matthias Walther compares the repatriation of German and French career agents into the external labor markets of their parent country career fields. A qualitative content analysis of 40 semi-structured interviews shows that the German and French career agents’ career capital and habitus develops during expatriation, which has an important impact on the re-integration into the parent country career field. The Author shows that in an international career mobility context, the rules of the game change compared to the rules in a pure national career context, which challenges the pertinence of national career models in understanding repatriation in a Franco-German context.
Offers a potted history of the German Federal Constitutional Court, one of the most influential constitutional courts in recent years. It examines the development of the court and its interaction with the German basic law, its approach to judicial reasoning, and its significance for contemporary constitutional theory.
Counselling and psychotherapy are effective to the extent that they promote the creativity of clients and patients. Creativity is both a lifestyle and a health resource. A creative lifestyle implies learning to be the authors of our own lives and a creative approach to our inner lives and our social environment gives us coherence and authenticity. This book derives creative principles for counselling and psychotherapy from practical modern approaches in these fields, as well as from psychoanalysis, hermeneutics, and new concepts of creativity itself. The creative attitude central to this represents an integrative basis for the differential application of various counselling and treatment techniques. Creative counselling serves to assist in coping with distress and clearly defined conflicts, and encourages personal and professional development. Creative psychotherapy is an aspect of dynamic, analytic and integrative psychotherapy. The hermeneutic principles – memory, narrative shaping, interactional experience – are activated with a view to ridding patients of psychopathological symptoms. In the modern world with all its challenges, creative counselling and psychotherapy are of outstanding importance. The book outlines a readily understandable, vital, and creative approach to the practice of counselling and psychotherapy in the service of the development of personal and social creativity.
The spectral geometry of infinite graphs deals with three major themes and their interplay: the spectral theory of the Laplacian, the geometry of the underlying graph, and the heat flow with its probabilistic aspects. In this book, all three themes are brought together coherently under the perspective of Dirichlet forms, providing a powerful and unified approach. The book gives a complete account of key topics of infinite graphs, such as essential self-adjointness, Markov uniqueness, spectral estimates, recurrence, and stochastic completeness. A major feature of the book is the use of intrinsic metrics to capture the geometry of graphs. As for manifolds, Dirichlet forms in the graph setting offer a structural understanding of the interaction between spectral theory, geometry and probability. For graphs, however, the presentation is much more accessible and inviting thanks to the discreteness of the underlying space, laying bare the main concepts while preserving the deep insights of the manifold case. Graphs and Discrete Dirichlet Spaces offers a comprehensive treatment of the spectral geometry of graphs, from the very basics to deep and thorough explorations of advanced topics. With modest prerequisites, the book can serve as a basis for a number of topics courses, starting at the undergraduate level.
This volume presents a broad comparative anatomical approach towards the functional morphology of the middle ear of palaeognathous birds (ostrich, rhea, tinamous, emu, cassowary, kiwi) and basal neognathous birds. It presents the most complete and thoroughly studied source of material on this field. For the first time it became possible to develop exact images of "non-structures" like the air-filled spaces of the avian skull by using non-invasive CT-techniques, computer-aided 3D-reconstruction, and morphometry, and to evaluate their functional importance for sound transmission and amplification through the middle ear. A series of air brush drawings represent detailed three-dimensional images of middle ear structures and the pneumatic spaces of the octic region of the skull.
