In many rich democracies, access to financial markets is now a prerequisite for fully participating in labor and housing markets and pursuing educational opportunities. Indebted Societies introduces a new social policy theory of everyday borrowing to examine how the rise of credit as a private alternative to the welfare state creates a new kind of social and economic citizenship. Andreas Wiedemann provides a rich study of income volatility and rising household indebtedness across OECD countries. Weaker social policies and a flexible knowledge economy have increased costs for housing, education, and raising a family - forcing many people into debt. By highlighting how credit markets interact with welfare states, the book helps explain why similar groups of people are more indebted in some countries than others. Moreover, it addresses the fundamental question of whether individuals, states, or markets should be responsible for addressing socio-economic risks and providing social opportunities.
In 1851, Heinrich Müller discovered what he called “radial fibers” and what we now call Müller cells, as the principal glial cells of the vertebrate retina. Later on, other glial cell types were found in the retina, including astrocytes, microglia, and even oligodendrocytes. It turned out that retinal glial cells are essential constituents of the tissue. For instance, Müller cells appear to constitute the “core” of columnar units of clonally and functionally related groups of neurons. Their primary function is to support neuronal functioning by guiding the light towards the photoreceptor cells, removing excess neurotransmitter molecules from extracellular space, and performing efficient clearance of excess extracellular potassium ions. The latter two functions are also crucial for neuronal survival and are coupled to water clearance which is also essential. Müller cells are capable of “sensing” neuronal activity and modifying it by the release of signal substances (gliotransmitters). In cases of retinal injuries the Müller cells become reactive, and all above-mentioned functions are impaired. However, such de-differentiated Müller cells may proliferate, and may even serve as stem cells for the regeneration of a damaged retina. As well as the Müller cells, retinal astrocytes and microglial cells are important players in retinal development and function. This book gives a comprehensive survey of the present knowledge on retinal glia.
Müller cells make up just 0.005% of the cells in our central nervous system. They do not belong to the more esteemed family of neuronal cells but to the glia, a family of cells that until recently were seen as mere filling material between the neurons. Now, however, all that has changed. Sharing the insights of more than a quarter century of research into Müller cells, Drs. Andreas Reichenbach and Andreas Bringmann of Leipzig University make a compelling case for the central role Müller cells play. Everyone agrees that the eye is a very special and versatile sense organ, yet it has turned out in recent years that Müller cells are peculiar and multipotent glial cells. In the retina of most vertebrates and even of many mammals, Müller cells are the only type of (macro- ) glial cells; thus, they are responsible for a wealth of neuron-supportive functions that, in the brain, rely upon a division of labour among astrocytes, oligodendrocytes, and ependymal cells. Even beyond such a role in the central nervous system as "model glia", Müller cells are adapted to several exciting roles in support of vision. They deliver the light stimuli to the photoreceptor cells in the inverted vertebrate retina, aid the processing of visual information, and are responsible for the homeostatic maintenance of the retinal extracellular milieu. In Müller Cells in the Healthy and Diseased Retina, aimed not just at neurobiologists but at anyone concerned with retinal degeneration, every angle of Müller cells is covered, from an introduction to their basic properties, through their roles as 'light cables' and 'shock absorbers', to the part they play in diseases and disorders of the eye. Once these have all been covered in detail, the authors move on to discuss the future direction of research into these small but potent cellular phenomena. About the Authors Dr. Andreas Reichenbach was born in 1950 in Leipzig, Germany. He studied medicine and specialized as a physiologist, working on the mammalian retina. Since 1984, he has focused his efforts - and those of a growing number of fellows in his team - on Müller cell research. He has held a professorship at Leipzig University since 1994. After studying biology, Dr. Andreas Bringmann (* 1960) worked in the field of systemic neurophysiology until he was inspired in 1996 by Andreas Reichenbach to research the most interesting cell, the Müller cell. He is now in the Department of Ophthalmology of the University of Leipzig where he is the head of the Basic Research Laboratory
Leopold von Ranke endeavoured to understand political order within its own historical context. To understand the nature of historical phenomena, such as an institution or an idea, one had to consider its historical development and the changes it underwent over a period of time. Historical epochs, Ranke argued, should not be judged according to predetermined contemporary values or ideas. Rather, they had to be understood on their own terms by empirically establishing history ‘as things really were.’ Ranke’s influence on History as a modern discipline is thus evident, and this is the first volume in English to chart his life and works for a hundred years.
Andreas Hazir is investigating the door seal contribution to the interior noise level of production vehicles. These investigations contain experimental contribution analyses of real production vehicles and of academic test cases as well as the development of a simulation methodology for noise transmission through sealing systems and side windows. The simulations are realized by coupling transient computational aeroacoustics of the exterior flow to nonlinear finite element simulations of the structural transmission. By introducing a linear transmission model, the setup and computational costs of the seal noise transmission are significantly reduced, resulting in the feasibility of numerical contribution analyses of real production vehicles.
How long have composites been around? Where does the classical laminate theory come from? Who made the first modern fiber composite? This work in the history of materials science is the first examination of the strategies employed in the nineteenth and twentieth centuries in researching and developing hybrid materials.

This book presents the development and importance of composite materials within historical context. The content includes Early composite materials The development of composite materials in the industrial nineteenth century Composites in twentieth-century polymer chemistry The development of hybrid material systems in the second half of the twentieth century Summary. The author: Dr. Andreas T. Haka is an engineer and historian of science and technology. He is currently a lecturer in the Section for the History of Science and Technology at the University of Stuttgart. His main focus is on the history and practice of materials research, raw materials, materials science and technological constructive design, scientific networks, and research technologies.
The patristic principle demands that theological quarrels be settled by resorting to the church fathers. This volume presents the first comprehensive reflexion on the historical evolution of the present crisis of this ancient theological principle. Focusing on the theory of the consensus quinquesaecularis, the author surveys the development of patristic authority from the 16th to the 20th centuries and relates it to other problems of the Church in modern times such as the crisis of tradition, the conflict between ecclesiastical authority and academic theology, and ecumenism. The concluding chapter tackles the question whether a renewal of the patristic principle is possible and feasible today.

When comparing the laws of different jurisdictions, one often sees only the forest or the trees. This is particularly problematic in comparative company law, where students hope both to understand the overall framework of the law and grasp its practical application. This text's structure, now in its second edition, solves that dilemma. Chapters open with discursive analyses of the law in each of Germany, the UK and the US (Delaware, the ABA Model Business Corporation Act, and federal securities laws) and set out the high-level governing framework, particularly for the EU and its member states. This analysis is succinct and pointed, with numerous references to both the law and leading scholarship. The whole text is arranged to highlight comparative aspects. Diagrams are used where helpful. Chapters close with edited judicial decisions from at least two of the jurisdictions discussed, which allows fresh exploration of comparison in more detail, and pointed questions to guide class discussion.
A new computational and dimensional approach to understanding and classifying mental disorders: modeling key learning and decision-making mechanisms across different mental disorders. Even as researchers look for neurobiological correlates of mental disorders, many of these disorders are still classified solely according to the manifestation of clinical symptoms. Neurobiological findings rarely help diagnose a specific disease or predict its outcome. Although current diagnostic categories are questionable (sometimes labeling common states of human suffering as disorders), traditional neuroimaging approaches are not sophisticated enough to capture the neurobiological markers of mental disorder. In this book, Andreas Heinz proposes a computational and dimensional approach to understanding and classifying mental disorders: modeling key learning and decision-making mechanisms across different mental disorders. Such an approach focuses on the malleability and diversity of human behavior and its biological underpinnings. Heinz explains basic learning mechanisms and their effects on human behavior, focusing not on single disorders but on how such mechanisms work in a multitude of mental states. For example, he traces alterations in dopamine-reinforcement learning in psychotic, affective, and addictive disorders. He investigates to what extent these basic dimensions of mental disorders can account for such syndromes as craving and loss of control in addiction, positive and negative mood states in affective disorders, and the altered experience of self and world associated with psychotic states. Finally, Heinz explores the clinical and therapeutic implications of such accounts. He argues that a focus on learning mechanisms, with its emphasis on human creativity and resilience, should help reduce the stigma of mental disorder.
This book presents an overview of a new group of progenitor stem cells. Their origins were originally detected in light- and electron microscopical sections of plastic embedded human embryonal and fetal organs. The distribution of these cells can result in a large quantity of ectopic stem cells. The observation of these ectopic stem cells leads us to postulate the existence of a basic wave of stem cell progenitors. This process proceeds earlier and independently from germ cell migration. This first wave of progenitor stem cell migration initially reaches the peri-aortal AMG-region (Aortal-Mesonephric-Gonadal region). From here, some of these progenitor cells enter the aorta, are distributed through the vascular system and become the embryonal stem cells (reserve cells) in many peripheral tissues. A second part delivers progenitor cells for the adrenal 'anlage'. Within the peripheral Zona definitiva of the adrenal cortex the progenitor cells multiplicate and subsequently leave the adrenal cortex through a gate of the capsule. The progenitor cells arrive at the pre-aortal sympathic plexus ('second brain'). Within the plexus ganglia they form new organ-like clusters, the paraganglia. In a second process the progenitor cells (Chromaffine cells) enter sympathetic nerve bundles. Here an 'axonal migration' starts, which guides the progenitor cells to several peripheral organs. During this migration process the stem cells develop into their final state. In the adrenal cortex the ingrowing nerves guide the stem cells to the adrenal medulla. In the pancreas the ingrowing nerve fibers guide the stem cells to the islets. These newly detected stem cells represent a specific developmental step which is found only in humans.

Andreas Loewe and Katherine Firth elucidate Luther’s theory and practice of the arts to reach audiences and convince them of his Reformation message using a range of strategies, including music, images and drama.
Using many unpublished and other primary sources as well as interviews with aides and associates of Hindenburg, the author shows in Hindenburg and the Weimar Republic how this proud and cautious man, naive in politics and preoccupied with his reputation among his fellow generals, failed to act in crucial situations, or hesitated until action was futile. He examines in detail Hindenburg's role during the fateful days when Hitler was forcing his way to the top, scheming to overthrow the republic of which President Hindenburg eventually appointed him chancellor. Originally published in 1964. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
In light of the dramatic growth and rapid institutionalization of human-animal studies in recent years, it is somewhat surprising that only a small number of publications have proposed practical and theoretical approaches to teaching in this inter- and transdisciplinary field. Featuring eleven original pedagogical interventions from the social sciences and the humanities as well as an epilogue from ecofeminist critic Greta Gaard, the present volume addresses this gap and responds to the demand by both educators and students for pedagogies appropriate for dealing with environmental crises. The theoretical and practical contributions collected here describe new ways of teaching human-animal studies in different educational settings and institutional contexts, suggesting how learners – equipped with key concepts such as agency or relationality – can develop empathy and ethical regard for the more-than-human world and especially nonhuman animals. As the contributors to this volume show, these cognitive and affective goals can be achieved in many curricula in secondary and tertiary education. By providing learners with the tools to challenge human exceptionalism in its various guises and related patterns of domination and exploitation in and outside the classroom, these interventions also contribute to a much-needed transformation not only of today's educational systems but of society as a whole. This volume is an invitation to beginners and experienced instructors alike, an invitation to (re)consider how we teach human-animal studies and how we could and should prepare learners for an uncertain future in, ideally, a more egalitarian and just multispecies world. With contributions by Roman Bartosch, Liza B. Bauer, Alexandra Böhm, Micha Gerrit Philipp Edlich, Greta Gaard, Björn Hayer, Andreas Hübner, Michaela Keck, Maria Moss, Jobst Paul, Mieke Roscher, Pamela Steen, and Nils Steffensen.

Is mankind alone in the universe? Will we ever encounter intelligent life beyond Earth? These questions have been asked for centuries. Recent advances in the fields of astrophysics, astronomy and astrobiology make it more likely than ever before, that Earth may not be the only inhabited planet, and that humanity may not the only intelligent species in the universe. What would be the consequences of contact with an extraterrestrial intelligence? This question is at the heart of the emerging discipline of exosociology. According to the authors, first contact with an extraterrestrial intelligence poses enormous risks for humanity. These risks come not only from extraterrestrials, but above all from ourselves. We should be prepared. Michael Schetsche and Andreas Anton's comprehensive introduction to exosociology was first published in German in 2019. The book has been widely acclaimed in Germany and internationally. It is now available in English for the first time.
Despite the increasing interest in multidimensional combustion engine simulation from researchers and industry, the field of application has been restricted to stationary operating points for turbocharged engines. Andreas Kächele presents a 3D-CFD approach to extend the simulation into the transient regime, enabling the detailed analysis of phenomena during changes in engine operating point. The approach is validated by means of a virtual hot gas test bench and experiments on a two-cylinder engine.

This book treats the mechanical behavior of one-dimensional sandwich structures, a typicaloncept in the context of lightweight design. Such structures are composed of different constituent (e.g., layers) in order to achieve overall properties, which are better than for a single component alone. This book covers the basic mechanical load cases, i.e., tension/compression, bending, and shear. Based on this knowledge, different failure modes, i.e., plastic yielding, and global and local instabilities are investigated. In addition, an introduction to classic optimization problems, i.e., the formulation of an objective function (e.g., the weight of a structure) and corresponding restrictions, is included. The consideration here is limited to one- or two-dimensional design spaces, i.e., with a maximum of two design variables. For such simple cases, the minimum of the objective function can often be determined using analytical or graphical methods.

In cryptography, ciphers is the technical term for encryption and decryption algorithms. They are an important sub-family that features high speed and easy implementation and are an essential part of wireless internet and mobile phones. Unlike block ciphers, stream ciphers work on single bits or single words and need to maintain an internal state to change the cipher at each step. Typically stream ciphers can reach higher speeds than block ciphers but they can be more vulnerable to attack. Here, mathematics comes into play. Number theory, algebra and statistics are the key to a better understanding of stream ciphers and essential for an informed decision on their safety. Since the theory is less developed, stream ciphers are often skipped in books on cryptography. This book fills this gap. It covers the mathematics of stream ciphers and its history, and also discusses many modern examples and their robustness against attacks. Part I covers linear feedback shift registers, non-linear combinations of LFSRs, algebraic attacks and irregular clocked shift registers. Part II studies some special ciphers including the security of mobile phones, RC4 and related ciphers, the eStream project and the blum-blum-shub generator and related ciphers. Stream Ciphers requires basic knowledge of algebra and linear algebra, combinatorics and probability theory and programming. Appendices in Part III help the reader with the more complicated subjects and provides the mathematical background needed. It covers, for example, complexity, number theory, finite fields, statistics, combinatorics. Stream Ciphers concludes with exercises and solutions and is directed towards advanced undergraduate and graduate students in mathematics and computer science.
An archaeological and art-historical study of the images and monuments of Roman 'client' kings in the Near East from the Taurus to Edom during the transitional period between 100 BC and AD 100. Kropp treats images and monuments as historical documents and aims at uncovering royal identities and ideological aspirations.
This book presents important contributions to modern theories concerning the distribution theory applied to convex analysis (convex functions, functions of lower semicontinuity, the subdifferential of a convex function). The authors prove several basic results in distribution theory and present ordinary differential equations and partial differential equations by providing generalized solutions. In addition, the book deals with Sobolev spaces, which presents aspects related to variation problems, such as the Stokes system, the elasticity system and the plate equation. The authors also include approximate formulations of variation problems, such as the Galerkin method or the finite element method. The book is accessible to all scientists, and it is especially useful for those who use mathematics to solve engineering and physics problems. The authors have avoided concepts and results contained in other books in order to keep the book comprehensive. Furthermore, they do not present concrete simplified models and pay maximal attention to scientific rigor.
