Book excerpt: Space is again in the headlines. E-billionaires Jeff Bezos and Elon Musk are planning to colonize Mars. President Trump wants a "Space Force" to achieve "space dominance" with expensive high-tech weapons. The space and nuclear arms control regimes are threadbare and disintegrating. Would-be asteroid collision diverters, space solar energy collectors, asteroid miners, and space geo-engineers insistently promote their Earth-changing mega-projects. Given our many looming planetary catastrophes (from extreme climate change to runaway artificial superintelligence), looking beyond the earth for solutions might seem like a sound strategy for humanity. And indeed, bolstered by a global network of fervent space advocates-and seemingly rendered plausible, even inevitable, by oceans of science fiction and the wizardly of modern cinema-space beckons as a fully hopeful path for human survival and flourishing, a positive future in increasingly dark times. But despite even basic questions of feasibility, will these many space ventures really have desirable effects, as their advocates insist? In the first book to critically assess the major consequences of space activities from their origins in the 1940s to the present and beyond, Daniel Deudney argues in Dark Skies that the major result of the "Space Age" has been to increase the likelihood of global nuclear war, a fact conveniently obscured by the failure of recognize that nuclear-armed ballistic missiles are inherently space weapons. The most important practical finding of Space Age science, also rarely emphasized, is the discovery that we live on Oasis Earth, tiny and fragile, and teeming with astounding life, but surrounded by an utterly desolate and inhospitable wilderness stretching at least many trillions of miles in all directions. As he stresses, our focus must be on Earth and nowhere else. Looking to the future, Deudney provides compelling reasons why space colonization will produce new threats to human survival and not alleviate the existing ones. That is why, he argues, we should fully relinquish the quest. Mind-bending and profound, Dark Skies challenges virtually all received wisdom about the final frontier.

This book was released on 2019-09-09 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is focused on the recent developments on problems of probability model uncertainty by using the notion of nonlinear expectations and, in particular, sublinear expectations. It provides a gentle coverage of the theory of nonlinear expectations and related stochastic analysis. Many notions and results, for example, G-normal distribution, G-Brownian motion, G-Martingale representation theorem, and related stochastic calculus are first introduced or obtained by the author. This book is based on Shige Peng’s lecture notes for a series of lectures given at summer schools and universities worldwide. It starts with basic definitions of nonlinear expectations and their relation to coherent measures of risk, law of large numbers and central limit theorems under nonlinear expectations, and develops into stochastic integral and stochastic calculus under G-expectations. It ends with recent research topic on G-Martingale representation theorem and G-stochastic integral for locally integrable processes. With exercises to practice at the end of each chapter, this book can be used as a graduate textbook for students in probability theory and mathematical finance. Each chapter also concludes with a section Notes and Comments, which gives history and further references on the material covered in that chapter. Researchers and graduate students interested in probability theory and mathematical finance will find this book very useful.

Book excerpt: An insightful investigation into the mechanisms underlying the predictive functions of neural networks—and their ability to chart a new path for AI. Prediction is a cognitive advantage like few others, inherently linked to our ability to survive and thrive. Our brains are awash in signals that embody prediction. Can we extend this capability more explicitly into synthetic neural networks to improve the function of AI and enhance its place in our world? Gradient Expectations is a bold effort by Keith L. Downing to map the origins and anatomy of natural and artificial neural networks to explore how, when designed as predictive modules, their components might serve as the basis for the simulated evolution of advanced neural network systems. Downing delves into the known neural architecture of the mammalian brain to illuminate the structure of predictive networks and determine more precisely how the ability to predict might have evolved from more primitive neural circuits. He then surveys past and present computational neural models that leverage predictive mechanisms with biological plausibility, identifying elements, such as gradients, that natural and artificial networks share. Behind well-founded predictions lie gradients, Downing finds, but of a different scope than those that belong to today’s deep learning. Digging into the connections between predictions and gradients, and their manifestation in the brain and neural networks, is one compelling example of how Downing enriches both our understanding of such relationships and their role in strengthening AI tools. Synthesizing critical research in neuroscience, cognitive science, and connectionism, Gradient Expectations offers unique depth and breadth of perspective on predictive neural-network models, including a grasp of predictive neural circuits that enables the integration of computational models of prediction with evolutionary algorithms.

Book excerpt: The algebraic theory of corner subrings introduced by Lam (as an abstraction of the properties of Peirce corners eRe of a ring R associated with an idempotent e in R) is investigated here in the context of Banach and C*-algebras. We propose a general algebraic approach which includes the notion of ranges of (completely) contractive conditional expectations on C*-algebras and on ternary rings of operators, and we investigate when topological properties are consequences of the algebraic assumptions. For commutative C*-algebras we show that dense corners cannot be proper and that self-adjoint corners must be closed and always have closed complements (and may also have non-closed complements). For C*-algebras we show that Peirce corners and some more general corners are similar to self-adjoint corners. We show uniqueness of complements for certain classes of corners in general C*-algebras, and establish that a primitive C*-algebra must be prime if it has a prime Peirce corner. Further we consider corners in ternary rings of operators (TROs) and characterise corners of Hilbertian TROs as closed subspaces.

Available in PDF, EPUB and Kindle. Book excerpt: Rising Expectations examines the current attempts to enlist religious congregations as partners in social services and community development. It highlights stark demographic realities about urban congregations in order to challenge current assumptions about welfare reform and to encourage realistic expectations for the future. Both governmental officials and civic leaders are calling on religious congregations to become more active partners in social welfare reforms, especially through Charitable Choice. Based on research conducted in Indianapolis, Indiana, Farnsley examines the context for those changes and evaluates the current and potential role for congregations as community development agencies and social service providers. Farnsley begins with an assessment of congregations, seen as one interdependent piece in a complex urban environment. He then deals with the three basic assumptions about congregations that drive contemporary faith-based reforms: "How well do congregations know their neighbors?" "Is smaller better?" and "Can congregations impart values?" Finally, the book considers plans for future implementation or expansion of reform.

Book excerpt: Recently economists have more and more focussed on scenarios in which agents' views of the world may be erroneous. These notes introduce the concept of perfect forecasting rules which provide best least-squares predictions along the evolution of an economic system. The framework for nonparametric adaptive learning schemes is developed and it is argued that plausible learning schemes should aim at estimating a perfect forecasting rule taking into account the correct feedback structure of an economy. A link is provided between the traditional rational-expectations view and recent behavioristic approaches.

This book describes how the retailisation of public domains affects our everyday life and our use of the built environment. Taking an architectural and territorial perspective on this issue, it looks at how retail and consumption spaces have changed and territorialised urban life in different ways. It then develops a methodology and a set of concepts to describe and understand the role of architecture in these territorial transformations.

This book was released on 2018-03-19 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: From Pavlov's dog expecting food when hearing a bell to stereotypes as expectations about other people’s behaviour, from Bandura’s self-efficacy as expectation for success and failure of one’s own behaviour to the "predictive brain" concept in current perception theories: expectations have been a central construct in different areas of psychological research. In each of these areas, specific concepts, theoretical approaches, and empirical methods have been developed to explain when and why expectations persist and when they do not. Many theories assume that expectations are likely to change in the face of disconfirming evidence. However, sometimes expectations persist even though they are empirically violated, suggesting that they can be “sticky” under certain circumstances. But what are these circumstances? And what are the psychological mechanisms that can explain why and when expectations persist or change after being confronted with expectation-violating evidence? Each contribution of the current book offers insights into individuals’ reactions to violations of expectations. They show that many pieces of the puzzle have been collected in the many sub-displiclines of psychology and that putting them together in an integrative fashion stays a fascinating enterprise.

Available in PDF, EPUB and Kindle. Book excerpt: Evaluating statistical procedures through decision and game theory, as first proposed by Neyman and Pearson and extended by Wald, is the goal of this problem-oriented text in mathematical statistics. First-year graduate students in statistics and other students with a background in statistical theory and advanced calculus will find a rigorous, thorough presentation of statistical decision theory treated as a special case of game theory. The work of Borel, von Neumann, and Morgenstern in game theory, of prime importance to decision theory, is covered in its relevant aspects: reduction of games to normal forms, the minimax theorem, and the utility theorem. With this introduction, Blackwell and Professor Girshick look at: Values and Optimal Strategies in Games; General Structure of Statistical Games; Utility and Principles of Choice; Classes of Optimal Strategies; Fixed Sample-Size Games with Finite Ω and with Finite A; Sufficient Statistics and the Invariance Principle; Sequential Games; Bayes and Minimax Sequential Procedures; Estimation; and Comparison of Experiments. A few topics not directly applicable to statistics, such as perfect information theory, are also discussed. Prerequisites for full understanding of the procedures in this book include knowledge of elementary analysis, and some familiarity with matrices, determinants, and linear dependence. For purposes of formal development, only discrete distributions are used, though continuous distributions are employed as illustrations. The number and variety of problems presented will be welcomed by all students, computer experts, and others using statistics and game theory. This comprehensive and sophisticated introduction remains one of the strongest and most useful approaches to a field which today touches areas as diverse as gambling and particle physics.

Available in PDF, EPUB and Kindle. Book excerpt: This book explores the potential of quantum crystallography. The field accompanied the major milestones of x-ray diffraction and it has undergone a rapid evolution in the past few years. For this reason, some reflections are necessary in order to scrutinize the next steps and anticipate the future developments. After a short survey of the historical background and in depth description of the state of the art, some examples are provided of current and future applications of the know-how in this discipline. This implies attracting readership of both experts in the field and neophytes. The former will test their own views with the one exposed in the book; the newcomers, instead, will learn both what has been done and what could be done with quantum crystallography.

Available in PDF, EPUB and Kindle. Book excerpt: Among all the genres of literature, the novel has always held a fascination for the readers over the centuries. Rightly so, because it tells a story in a gripping and dramatic style, which often reminds them of their lives, sometimes transporting them into an imaginary world of entertainment and escape, and enabling them to forget their worries and concerns. The 19th century England was prodigious for the production of novels with such luminaries as William Makepeace Thackeray, Charles Dickens, the famous Bronte sisters—Charlotte Bronte, Anne Bronte and Emily Bronte—George Eliot and Thomas Hardy adorning the horizon. Among these, Dickens certainly holds a pride of place: his prodigious writings, predominantly novels, and his inimitable style bear testimony to this. The child figure is ubiquitous in all his novels—from Oliver Twist, Dombey and Son to Hard Times and Great Expectations. The child is sometimes the victim and sometimes the reminder of the innocence lost in a materialistic world. Great Expectations is a fascinating novel told with remarkable drama, humour and irony. It is a gripping story, the story of Pip, the orphan boy adopted by Mr. Joe Gragery, a blacksmith. Pip has both good luck and great expectations; but then he loses both. Through his rise and fall, Pip learns how to find happiness and, in the process, falls in love. Pip is neither a hero nor an antihero. He is just an ordinary human being who experiences myriad emotions—fright, love, grief, misery and happiness. As in his other novels, Dickens draws memorable and haunting characters in this novel, too, and also exposes the rampant corruption prevalent during the period. Besides a comprehensive Preface by the Editor, the book gives the actual text, followed by specially written critical essays on the novel by experts in the field, each offering insights on different aspects of narrative, themes and culture. Undergraduate and postgraduate students of English Literature as well as researchers in the field should find this book extremely useful and immensely readable.

This book was released on 2012-01-06 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: A crucial challenge for economists is figuring out how people interpret the world and form expectations that will likely influence their economic activity. Inflation, asset prices, exchange rates, investment, and consumption are just some of the economic variables that are largely explained by expectations. Here George Evans and Seppo Honkapohja bring new explanatory power to a variety of expectation formation models by focusing on the learning factor. Whereas the rational expectations paradigm offers the prevailing method to determining expectations, it assumes very theoretical knowledge on the part of economic actors. Evans and Honkapohja contribute to a growing body of research positing that households and firms learn by making forecasts using observed data, updating their forecast rules over time in response to errors. This book is the first systematic development of the new statistical learning approach. Depending on the particular economic structure, the economy may converge to a standard rational-expectations or a "rational bubble" solution, or exhibit persistent learning dynamics. The learning approach also provides tools to assess the importance of new models with expectational indeterminacy, in which expectations are an independent cause of macroeconomic fluctuations. Moreover, learning dynamics provide a theory for the evolution of expectations and selection between alternative equilibria, with implications for business cycles, asset price volatility, and policy. This book provides an authoritative treatment of this emerging field, developing the analytical techniques in detail and using them to synthesize and extend existing research.
