Disorder is one of the predominant topics in science today. The present text is devoted to the mathematical studyofsome particular cases ofdisordered systems. It deals with waves in disordered media. To understand the significance of the influence of disorder, let us start by describing the propagation of waves in a sufficiently ordered or regular environment. That they do in fact propagate is a basic experience that is verified by our senses; we hear sound (acoustic waves) see (electromagnetic waves) and use the fact that electromagnetic waves travel long distances in many aspects ofour daily lives. The discovery that disorder can suppress the transport properties of a medium is oneof the fundamental findings of physics. In its most prominent practical application, the semiconductor, it has revolutionized the technical progress in the past century. A lot of what we see in the world today depends on that relatively young device. The basic phenomenon of wave propagation in disordered media is called a metal-insulator transition: a disordered medium can exhibit good transport prop erties for waves ofrelatively high energy (like a metal) and suppress the propaga tion of waves of low energy (like an insulator). Here we are actually talking about quantum mechanical wave functions that are used to describe electronic transport properties. To give an initial idea of why such a phenomenon could occur, we have to recall that in physical theories waves are represented by solutions to certain partial differential equations. These equations link time derivatives to spatial derivatives.
The renormalization group (RG) has nowadays achieved the status of a meta-theory, which is a theory about theories. The theory of the RG consists of a set of concepts and methods which can be used to understand phenomena in many different ?elds of physics, ranging from quantum ?eld theory over classical statistical mechanics to nonequilibrium phenomena. RG methods are particularly useful to understand phenomena where ?uctuations involving many different length or time scales lead to the emergence of new collective behavior in complex many-body systems. In view of the diversity of ?elds where RG methods have been successfully applied, it is not surprising that a variety of apparently different implementations of the RG idea have been proposed. Unfortunately, this makes it somewhat dif?cult for beginners to learn this technique. For example, the ?eld-theoretical formulation of the RG idea looks at the ?rst sight rather different from the RG approach pioneered by Wilson, the latter being based on the concept of the effective action which is ite- tively calculated by successive elimination of the high-energy degrees of freedom. Moreover, the Wilsonian RG idea has been implemented in many different ways, depending on the particular problem at hand, and there seems to be no canonical way of setting up the RG procedure for a given problem.
This book is a comprehensive development and defense of one of the guiding assumptions of evolutionary psychology: that the human mind is composed of a large number of semi-independent modules. The Architecture of the Mind has three main goals. One is to argue for massive mental modularity. Another is to answer a 'How possibly?' challenge to any such approach. The first part of the book lays out the positive case supporting massive modularity. It also outlines how the thesis should best be developed, and articulates the notion of 'module' that is in question. Then the second part of the book takes up the challenge of explaining how the sorts of flexibility and creativity that are distinctive of the human mind could possibly be grounded in the operations of a massive number of modules. Peter Carruthers's third aim is to show how the various components of the mind are likely to be linked and interact with one another - indeed, this is crucial to demonstrating how the human mind, together with its familiar capacities, can be underpinned by a massively modular set of mechanisms. He outlines and defends the basic framework of a perception / belief / desire / planning / motor-control architecture, as well as detailing the likely components and their modes of connectivity. Many specific claims about the place within this architecture of natural language, of a mind-reading system, and others are explained and motivated. A number of novel proposals are made in the course of these discussions, one of which is that creative human thought depends upon a prior kind of creativity of action. Written with unusual clarity and directness, and surveying an extensive range of research in cognitive science, this book will be essential reading for anyone with an interest in the nature and organization of the mind.
Through an examination of material and institutional circumstances, through the study of work shop practices and of technical and aesthetic experimentation, this book seeks to give an account of the ways in which Renaissance prints were realized, distributed, acquired, and handled by their public.
Conflict is inherent in virtually every aspect of human relations, from sport to parliamentary democracy, from fashion in the arts to paradigmatic challenges in the sciences, and from economic activity to intimate relationships. Yet, it can become among the most serious social problems humans face when it loses its constructive features and becomes protracted over time with no obvious means of resolution. This book addresses the subject of intractable social conflict from a new vantage point. Here, these types of conflict represent self-organizing phenomena, emerging quite naturally from the ongoing dynamics in human interaction at any scale—from the interpersonal to the international. Using the universal language and computational framework of nonlinear dynamical systems theory in combination with recent insights from social psychology, intractable conflict is understood as a system locked in special attractor states that constrain the thoughts and actions of the parties to the conflict. The emergence and maintenance of attractors for conflict can be described by means of formal models that incorporate the results of computer simulations, experiments, field research, and archival analyses. Multi-disciplinary research reflecting these approaches provides encouraging support for the dynamical systems perspective. Importantly, this text presents new views on conflict resolution. In contrast to traditional approaches that tend to focus on basic, short-lived cause-effect relations, the dynamical perspective emphasizes the temporal patterns and potential for emergence in destructive relations. Attractor deconstruction entails restoring complexity to a conflict scenario by isolating elements or changing the feedback loops among them. The creation of a latent attractor trades on the tendency toward multi-stability in dynamical systems and entails the consolidation of incongruent (positive) elements into a coherent structure. In the bifurcation scenario, factors are identified that can change the number and types of attractors in a conflict scenario. The implementation of these strategies may hold the key to unlocking intractable conflict, creating the potential for constructive social relations.

A neuroscientific perspective on the mind–body problem that focuses on how the brain actually accomplishes mental causation. The issues of mental causation, consciousness, and free will have vexed philosophers since Plato. In this book, Peter Tse examines these unresolved issues from a neuroscientific perspective. In contrast with philosophers who use logic rather than data to argue whether mental causation or consciousness can exist given unproven first assumptions, Tse proposes that we instead listen to what neurons have to say. Tse draws on exciting recent neuroscientific data concerning how informational causation is realized in physical causation at the level of NMDA receptors, synapses, dendrites, neurons, and neuronal circuits. He argues that a particular kind of strong free will and “downward” mental causation are realized in rapid synaptic plasticity. Such informational causation cannot change the physical basis of information realized in the present, but it can change the physical basis of information that may be realized in the immediate future. This gets around the standard argument against free will centered on the impossibility of self-causation. Tse explores the ways that mental causation and qualia might be realized in this kind of neuronal and associated information-processing architecture, and considers the psychological and philosophical implications of having such an architecture realized in our brains.

Science and engineering have been great sources of problems and inspiration for generations of mathematicians. This is probably true now more than ever as numerous challenges in science and technology are met by mathematicians. One of these challenges is understanding propagation of waves of different nature in systems of complex structure. This book contains the proceedings of the research conference, ``Waves in Periodic and Random Media''. Papers are devoted to a number of related themes, including spectral theory of periodic differential operators, Anderson localization and spectral theory of random operators, photonic crystals, waveguide theory, mesoscopic systems, and designer random surfaces. Contributions are written by prominent experts and are of interest to researchers and graduate students in mathematical physics.
From one of the most prominent biographers of the Nazi period, a new and provocative portrait of the figure behind the century's worst crimes Acclaimed historian Peter Longerich, author of Goebbels and Heinrich Himmler now turns his attention to Adolf Hitler in this new biography. While many previous portraits have speculated about Hitler's formative years, Longerich focuses on his central role as the driving force of Nazism itself. You cannot separate the man from the monstrous movement he came to embody. From his ascendance through the party's ranks to his final hours as Führer in April 1945, Longerich shows just how ruthless Hitler was in his path to power. He emphasizes Hitler's political skills as Germany gained prominence on the world's stage. Hitler's rise to, and ultimate hold on, power was more than merely a matter of charisma; rather, it was due to his ability to control the structure he created. His was an image constructed by his regime - an essential piece self-created of propaganda. This comprehensive biography is the culmination of Longerich's life-long pursuit to understand the man behind the century's worst crimes.
New insights offered by neuroscience have provoked discussions of the nature of human agency and responsibility.

To date, most network research contains one or more of five major problems. First, it tends to be atheoretical, ignoring the various social theories that contain network implications. Second, it explores single levels of analysis rather than the multiple levels out of which most networks are comprised. Third, network analysis has employed very little the insights from contemporary complex systems analysis and computer simulations. Foruth, it typically uses descriptive rather than inferential statistics, thus robbing it of the ability to make claims about the larger universe of networks. Finally, almost all the research is static and cross-sectional rather than dynamic. Theories of Communication Networks presents solutions to all five problems. The authors develop a multitheoretical model that relates different social science theories with different network properties. This model is multilevel, providing a network decomposition that applies the various social theories to all network levels: individuals, dyads, triples, groups, and the entire network. The book then establishes a model from the perspective of complex adaptive systems and demonstrates how to use Blanche, an agent-based network computer simulation environment, to generate and test network theories and hypotheses. It presents recent developments in network statistical analysis, the p* family, which provides a basis for valid multilevel statistical inferences regarding networks. Finally, it shows how to relate communication networks to other networks, thus providing the basis in conjunction with computer simulations to study the emergence of dynamic organizational networks.
Rich and intriguing."—Kirkus Reviews on The Last of All Possible Worlds "Convincing and haunting."—Publishers Weekly on The Temptation to Do Good Best-selling author Peter F. Drucker wrote just two novels. Here for the first time in paperback are both. In The Last of All Possible Worlds, royalty, bankers, lovers, and wives intertwine to create a vivid portrait of Europe in the early 1900s. We meet wise and worldly Prince Sobieski, Vienna’s ambassador in London, his enchanting wife, her English lover, and her enigmatic lifelong companion, Josefa. When Sobieski’s illegitimate daughter makes a demand of her influential father, the unspoken rules of the family are challenged. Sobieski’s world is further upset when two powerful merchant bankers, the tragic McGregor Hinton and the ambitious Julius von Mosenthal, arrive in London—both with their own requirements of the prince. The Temptation to Do Good tells the story of Father Heinz Zimmerman, the well-regarded president of an American Catholic university. When he attempts to help a chemistry teacher who has been denied tenure he accidentally opens the door to the underlying tensions in the university.

An intimate account of the Arab Spring, and Egypt’s past and present, seen through the eyes of a wide range of Egyptians: political operators, archaeologists and garbage collectors; women, the queer community and migrants.
Do we have introspective access to our own thoughts? Peter Carruthers challenges the consensus that we do: he argues that access to our own thoughts is always interpretive, grounded in perceptual awareness and sensory imagery. He proposes a bold new theory of self-knowledge, with radical implications for understanding of consciousness and agency.
Unraveling trauma in the body, brain and mind—a revolution in treatment. Now in 17 languages. In this culmination of his life’s work, Peter A. Levine draws on his broad experience as a clinician, a student of comparative brain research, a stress scientist and a keen observer of the naturalistic animal world to explain the nature and transformation of trauma in the body, brain and psyche. In an Unspoken Voice is based on the idea that trauma is neither a disease nor a disorder, but rather an injury caused by fright, helplessness and loss that can be healed by engaging our innate capacity to self-regulate high states of arousal and intense emotions. Enriched with a coherent theoretical framework and compelling case examples, the book elegantly blends the latest findings in biology, neuroscience and body-oriented psychotherapy to show that when we bring together animal instinct and reason, we can become more whole human beings.
Much progress has been made to understand the intricacies of the brain's workings. Some have claimed, and many assumed, that these findings have challenged faith in God to the point of destruction. Are we not mere neural machines? Are religious experiences not just 'in the mind', the products of abnormal 'brain events'? Is faith not just a side effect of evolution? Not so, according to neuroscientist Peter Clarke, after a lifetime's study of the brain. In this comprehensive book, the current state of neuroscientific evidence is weighed up alongside ideas of what it means to be human, the idea of the soul, near-death experiences, and questions of free will and responsibility. He engages with the leading thinkers in these areas, including Francis Crick, Richard Dawkins, Daniel Dennett, Sam Harris, and Daniel Wegner.
This monograph offers the first comprehensive treatment of the multi-faceted scholarly interests of Ole Worm, professor of medicine at the University of Copenhagen. Scholarship about Worm has focused mainly on Worm’s collecting and the creation of his cabinet of curiosity, the Museum Wormianum, resulting in Worm’s rationale for his research being largely overlooked. Worm shared his many interests with a number of other physicians of the age, but in terms of breadth, few matched the variety of his concerns. For a man who considered himself first and foremost a physician and anatomist, his interests in Paracelsianism and collecting can at times be baffling, while his interests in antiquarianism, runes, and chronology strike the modern reader as at odds with his medical and natural philosophical interests. It is important to comprehend that Worm’s multi-faceted interests in the created world were underpinned by his Lutheran, Melanchthonian natural philosophy, and this served to unify all Worm’s scholarly undertakings, inquiries, and experiments in the single aim of reaching a better understanding of God’s creation, the Book of Nature.
Conversation: Striving, Surviving, and Thriving presents a psychological-evolutionary rationale for everyday discourse and a method for analyzing conversations. As an evolved form of direct action, conversation empowers humans to relentlessly seek good physical and mental states by discovering life-enhancing messages and relationships. Properly analyzed conversations disclose our innermost desires and concerns, and promote self-enriching insights. Conversation: Striving, Surviving, and Thriving answers such questions as: What can I do to make my conversations more satisfying? What is conversational style? How is it that some people are chatty and others reticent? Where does conversational content come from? Why am I more likely to telephone my mother than my father? What are the similarities and differences between man-talk and woman-talk? Are some people simply not worth the conversational effort? Why is gossip enticing? Do I talk with the same persons about the same things? Incisive and eminently useful, Conversation: Striving, Surviving, and Thriving illuminates the hopes and dreams encoded in everyday banter, enabling us to more effectively talk our way to feeling good.
