The essential textbook on agent-based modeling—now fully updated and expanded Agent-Based and Individual-Based Modeling has become the standard textbook on the subject for classroom use and self-instruction. Drawing on the latest version of NetLogo and fully updated with new examples, exercises, and an enhanced text for easier comprehension, this is the essential resource for anyone seeking to understand how the dynamics of biological, social, and other complex systems arise from the characteristics of the agents that make up these systems. Steven Railsback and Volker Grimm lead students stepwise through the processes of designing, programming, documenting, and doing scientific research with agent-based models, focusing on the adaptive behaviors that make these models necessary. They cover the fundamentals of modeling and model analysis, introduce key modeling concepts, and demonstrate how to implement them using NetLogo. They also address pattern-oriented modeling, an invaluable strategy for modeling real-world problems and developing theory. This accessible and authoritative book focuses on modeling as a tool for understanding real complex systems. It explains how to pose a specific question, use observations from actual systems to design models, write and test software, and more. A hands-on introduction that guides students from conceptual design to computer implementation to analysis Filled with new examples and exercises and compatible with the latest version of NetLogo Ideal for students and researchers across the natural and social sciences Written by two leading practitioners Supported by extensive instructional materials at www.railsback-grimm-abm-book.com
Meta-X is a user-friendly computer program that allows students, teachers, and researchers to perform a metapopulation viability analysis i.e. to assess the extinction risk of (meta)populations on discrete, partially isolated patches of habitat, in a comfortable way. The CD comes with an extensive handbook which explains the basic concept of the program and takes you on a guided tour through a model experiment. It further provides the necessary scientific background on both metapopulation dynamics and population viability analysis. A special feature of Meta-X is that it supports comparative analyses of alternative scenarios. This predestines Meta-X to serve as an aid for decision making in conservation management and landscape planning. Furthermore, handbook and software together provide an invaluable help in research and teaching.
Individual-based models are an exciting and widely used new tool for ecology. These computational models allow scientists to explore the mechanisms through which population and ecosystem ecology arises from how individuals interact with each other and their environment. This book provides the first in-depth treatment of individual-based modeling and its use to develop theoretical understanding of how ecological systems work, an approach the authors call "individual-based ecology.? Grimm and Railsback start with a general primer on modeling: how to design models that are as simple as possible while still allowing specific problems to be solved, and how to move efficiently through a cycle of pattern-oriented model design, implementation, and analysis. Next, they address the problems of theory and conceptual framework for individual-based ecology: What is "theory"? That is, how do we develop reusable models of how system dynamics arise from characteristics of individuals? What conceptual framework do we use when the classical differential equation framework no longer applies? An extensive review illustrates the ecological problems that have been addressed with individual-based models. The authors then identify how the mechanics of building and using individual-based models differ from those of traditional science, and provide guidance on formulating, programming, and analyzing models. This book will be helpful to ecologists interested in modeling, and to other scientists interested in agent-based modeling.
Arno Schmidt (1914-1979) is considered one of the most daring and influential writers of postwar Germany; the Germanist Jeremy Adler has called him a "giant of postwar German literature." Schmidt was awarded the Fontane Prize in 1964 and the Goethe Prize in 1973, and his early fiction has been translated into English to high critical acclaim, but he is not a well-known figure in the English-speaking world, where his complex work remains at the margins of critical inquiry. Volker Langbehn's book introduces Schmidt to the English-speaking audience, with primary emphasis on his most famous novel, Zettel's Traum. One reviewer called the book an "elephantine monster" because of its unconventional size (folio format), length (1334 pages and over 10 million characters), and unique presentation of text in the form of notes, typewritten pages, parallel columns, and collages. The novel narrates the life of the main characters, Daniel Pagenstecher, Paul Jacobi and his wife Wilma, and their teenage daughter Franziska. In discussing the life and works of Edgar Allan Poe, the four engage in the problems connected with a translation of Poe. Langbehn's study investigates how literary language can mediate or account for the world of experiences and for concepts. Schmidt's use of unconventional presentation formats challenges us to analyze how we think about reading and writing literary texts. Instead of viewing such texts as a representation of reality, Schmidt's novel destabilizes this unquestioned mode of representation, posing a radical challenge to what contemporary literary criticism defines as literature. No comprehensive study of Zettel's Traum exists in English.Volker Langbehn is assistant professor of German at San Francisco State University.
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.

This brief, insightful biography of Martin Luther strips away the myths surrounding the Reformer to offer a more nuanced account of his life and ministry. Coinciding with the 500th anniversary of the Reformation, this accessible yet robustly historical and theological work highlights the medieval background of Luther's life in contrast to contemporary legends. Internationally respected church historian Volker Leppin explores the Catholic roots of Lutheran thought and locates Luther's life in the unfolding history of 16th-century Europe. Foreword by Timothy J. Wengert.
This book argues that in the digital era, a reinvention of democracy is urgently necessary. It discusses the mounting evidence showing that digitalisation is pushing classical parliamentary democracy to its limits, offering examples such as how living in a filter bubble and debating with political bots is profoundly changing democratic communication, making it more emotional, hysterical even, and less rational. It also explores how classical democracy involves long, slow thinking and decision processes, which don’t fit to the ever-increasing speed of the digital world, and examines the technical developments some fear will lead to governance by algorithms.In the digitalised world, democracy no longer functions as it has in the past. This does not mean waving goodbye to democracy – instead we need to reinvent it. How this could work is the central theme of this book.
WHITE WINE ENOLOGY could also be titled as SCIENCE AND PRACTICE OF WHITE WINEMAKING. It is characterized by two particular features: Firstly, it is authored by a practitioner who has worked his whole life in decision-making technical positions in the wine industry. Secondly, it is dedicated exclusively to the enology of white wines, and focuses its attention on flavor preservation rather than strategies that seek to obtain short-lived quality benefits. In doing so, it addresses one of the most important issues of white winemaking, which is the limited shelf life and flavor stability of most such wines, and shows how different white wine enology is from red. Due to the complex chemical process of white wine aging that goes well beyond oxidative aging, this book has a strong focus on sensory analysis throughout. It specifies the flavor-active compounds responsible for aging-related faults, identifies the chemical mechanisms of their formation, and clearly defines the decisive measures to take in order to mitigate them and improve flavor stability. While this book includes a deep treatment of the scientific fundaments of the different kinds of white wine aging, it also examines typical engineering issues common to commercial winemaking. Thus, it provides numerous practical hints and technical details of hands-on winery work and a valuable insight into the inherently cross-disciplinary nature of fine white winemaking. Extensive personal experience was decisive for this purpose. Volker Schneider was founder of the international consulting firm Schneider-Oenologie, which specialized in innovative winery operations, product development, quality control, and research. He has authored more than 450 technical articles and a range of scientific papers on these topics. He was also lecturer of enological chemistry at Geisenheim University.
A New York Times bestseller, this landmark biography of Hitler puts an emphasis on the man himself: his personality, his temperament, and his beliefs. Volker Ullrich's Hitler, the first in a two-volume biography, has changed the way scholars and laypeople alike understand the man who has become the personification of evil. Drawing on previously unseen papers and new scholarly research, Ullrich charts Hitler's life from his childhood through his experiences in the First World War and his subsequent rise as a far-right leader. Focusing on the personality behind the policies, Ullrich creates a vivid portrait of a man and his megalomania, political skill, and horrifying worldview. Hitler is an essential historical biography with unsettling resonance in contemporary times. “[A] fascinating Shakespearean parable about how the confluence of circumstance, chance, a ruthless individual and the willful blindness of others can transform a country — and, in Hitler’s case, lead to an unimaginable nightmare for the world.” —Michiko Kakutani, The New York Times Winner of the Los Angeles Times Book Prize for Biography
Ernst Specker has made decisive contributions towards shaping direc tions in topology, algebra, mathematical logic, combinatorics and algorith mic over the last 40 years. We have derived great pleasure from marking his seventieth birthday by editing the majority of his scientific publications, and thus making his work available in a unified form to the mathematical community. In order to convey an idea of the richness of his personality, we have also included one of his sermons. Of course, the publication of these Selecta can pay tribute only to the writings of Ernst Specker. It cannot adequately express his originality and wisdom as a person nor the fascination he exercises over his students, colleagues and friends. We can do no better than to quote from Hao Wang in the 'Festschrift' Logic and Algorithmic I: Specker was ill for an extended period before completing his formal education. He had the leisure to think over many things. This experi ence may have helped cultivating his superiority as a person. In terms of traditional Chinese categories, I would say there is a taoist trait in him in the sense of being more detached, less competitive, and more under standing. I believe he has a better sense of what is important in life and arranges his life better than most logicians. We are grateful to Birkhauser Verlag for the production of this Selecta volume. Our special thanks go to Jonas Meon for sharing with us his intimate knowledge of his friend Ernst Specker.

The energy transition not only has an impact on technical infrastructures but also leads to socio-economic changes. To evaluate the sustainability aspects of the German Energiewende, the authors have developed a monitoring system which includes 45 indicators and their corresponding target values for 2020, 2030, and 2050 as well as a rating system for the year 2020 based on a distance-to-target approach and traffic color lights.
A riveting account of the dictator’s final years, when he got the war he wanted but led his nation, the world, and himself to catastrophe—from the author of Hitler: Ascent “Skillfully conceived and utterly engrossing.” —The New York Times Book Review In the summer of 1939, Hitler was at the zenith of his power. Having consolidated political control in Germany, he was at the helm of a newly restored major world power, and now perfectly positioned to realize his lifelong ambition: to help the German people flourish and to exterminate those who stood in the way. Beginning a war allowed Hitler to take his ideological obsessions to unthinkable extremes, including the mass genocide of millions, which was conducted not only with the aid of the SS, but with the full knowledge of German leadership. Yet despite a series of stunning initial triumphs, Hitler’s fateful decision to invade the Soviet Union in 1941 turned the tide of the war in favor of the Allies. Now, Volker Ullrich, author of Hitler: Ascent 1889–1939, offers fascinating new insight into Hitler’s character and personality. He vividly portrays the insecurity, obsession with minutiae, and narcissistic penchant for gambling that led Hitler to overrule his subordinates and then blame them for his failures. When he ultimately realized the war was not winnable, Hitler embarked on the annihilation of Germany itself in order to punish the people who he believed had failed to hand him victory. A masterful and riveting account of a spectacular downfall, Ullrich’s rendering of Hitler’s final years is an essential addition to our understanding of the dictator and the course of the Second World War.

One of the most notable features of literature about "new economic geography" is a close association between theoretical and empirical work. In contrast to earlier research, theoretical studies are often much more strongly focused on real-world phenomena. At the same time, empirical work is often more closely tied to theoretical models. Instead of purely detecting possible stylized facts, considerable efforts have been made to test for the relevance of theoretical results.A major shortcoming of recent empirical work in urban economics is, however, the startling concentration on basically only two estimation strategies. Probably driven by limited data availability, most analyses are either cross-country studies which usually seek to explore a data set as rich as possible, or the studies examine single country data and then often focus on U.S. experiences.This book aims to provide a new - European - perspective. The basic idea is that a focus on European cities, apart from being interesting for itself, allows to combine both previous approaches. In particular, there is considerable cross-country variation while, in addition, also reliable historical data is available. Therefore, it is one of the contributions to compile a new data set of European cities which covers 13 countries and ranges from 1870 to 1990.This set of data is then applied to explore several hypotheses which have been recently proposed in literature. In particular, three sets of issues are discussed: the growth pattern of cities and their implications for Zipf's law, the relationship between trade openness and urban concentration, and the role of history for city growth. The results are often striking. In contrast to some previous findings, for instance, there is only weak evidence for random growth across cities. Also, the empirical evidence for an association between external trade and internal geography turns out to be shaky. Finally, it is argued that the urban dominance of Vienna after the dissolution of the Austro-Hungarian Empire in 1918 is evidence in favor of path dependence in city growth.Taken together, the book shows that the European experience provides a rich laboratory of real-world data which still waits to be explored.
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.
We live in a digital Media Society, in which pictures are becoming more and more important. So, human communication is increasingly becoming a visual communication. That is not a new finding. But the new question is: What does this development mean for the law? Up to now the law is the part of the society which is most sceptical towards images. Law has still resisted the visual temptation. This will not last for ever. The rush of pictures in everyday life and in every part of the society is much too strong - and it is even getting stronger. The invasion of images will change the character of modern law deeply. Modern law will become a Pictorial Law.What are the chances and the risks of Pictorial Law and visual law communication? This is the topic of the book.
