Aimed at graduate students, this book explores some of the core phenomena in non-equilibrium statistical physics. It focuses on the development and application of theoretical methods to help students develop their problem-solving skills. The book begins with microscopic transport processes: diffusion, collision-driven phenomena, and exclusion. It then presents the kinetics of aggregation, fragmentation and adsorption, where the basic phenomenology and solution techniques are emphasized. The following chapters cover kinetic spin systems, both from a discrete and a continuum perspective, the role of disorder in non-equilibrium processes, hysteresis from the non-equilibrium perspective, the kinetics of chemical reactions, and the properties of complex networks. The book contains 200 exercises to test students' understanding of the subject. A link to a website hosted by the authors, containing supplementary material including solutions to some of the exercises, can be found at www.cambridg

Political parties provide a crucial link between voters and politicians. This link takes a variety of forms in democratic regimes, from the organization of political machines built around clientelistic networks to the establishment of sophisticated programmatic parties. Latin American Party Systems provides a novel theoretical argument to account for differences in the degree to which political party systems in the region were programmatically structured at the end of the twentieth century. Based on a diverse array of indicators and surveys of party legislators and public opinion, the book argues that learning and adaptation through fundamental policy innovations are the main mechanisms by which politicians build programmatic parties. Marshalling extensive evidence, the book's analysis shows the limits of alternative explanations and substantiates a sanguine view of programmatic competition, nevertheless recognizing that this form of party system organization is far from ubiquitous and

The use of topological ideas to explore various aspects of graph theory, and vice versa, is a fruitful area of research. There are links with other areas of mathematics, such as design theory and geometry, and increasingly with such areas as computer networks where symmetry is an important feature. Other books cover portions of the material here, but there are no other books with such a wide scope. This book contains fifteen expository chapters written by acknowledged international experts in the field. Their well-written contributions have been carefully edited to enhance readability and to standardize the chapter structure, terminology and notation throughout the book. To help the reader, there is an extensive introductory chapter that covers the basic background material in graph theory and the topology of surfaces. Each chapter concludes with an extensive list of references.

Games in Economic Development examines the roots of poverty and prosperity through the lens of elementary game theory, illustrating how patterns of human interaction can lead to vicious cycles of poverty as well as virtuous cycles of prosperity. This book shows how both social norms and carefully designed institutions can help shape the 'rules of the game', making better outcomes in a game possible for everyone involved. The book is entertaining to read, it can be accessed with little background in development economics or game theory. Its chapters explore games in natural resource use; education; coping with risk; borrowing and lending; technology adoption; governance and corruption; civil conflict; international trade; and the importance of networks, religion, and identity, illustrating concepts with numerous anecdotes from recent world events. Comes complete with an appendix, explaining the basic ideas in game theory used in the book.

A potent exploration of the power of blockchains to reshape the future of the Internet--and how that affects us all--from highly influential entrepreneur and technology investor Chris Dixon The Internet of today is a far cry from its early promise of a decentralized, democratic network of creativity and innovation. In the past decade, the Internet has fallen under the control of a tiny group of massive companies like Apple, Google, and Facebook. In Read Write Own, tech visionary Chris Dixon argues that the dream of an open network for fostering creativity and entrepreneurship doesn't have to die, and that in fact it can, and must, be saved with blockchain networks, which he vitally separates from the currency-based speculation that it is unfortunately lumped together with--a distinction he calls "The Computer vs The Casino". With lucid and compelling prose--and drawing from his first-hand observations, mental models, and experiences over a 25-year career in the Internet industry--Dixon

A comprehensive study of a modern form of Hinduism that is growing in the place of its birth in the Indian state of Gujarat and among Indian immigrants in east Africa, Great Britain, and the United States. It is the most prominent form of transnational Hinduism because it creates networks that define and preserve ethnic and religious identity in the modern context of rapid mobility and communication. Founded by Sahajanand Swami or Swaminarayan (1781–1830), a religious reformer in a time of great social and political change in Gujarat, Swaminarayan Hinduism expounds a path of devotion to Swaminarayan as the final, perfect manifestation of God. Raymond Brady Williams provides a detailed introduction to the history, theology, discipline, and ritual of this important form of Hinduism. Based on and extending, with considerable updating and revision, his A New Face of Hinduism: The Swaminarayan Religion (1984), the book places Swaminarayan in the context of transnational Hinduism and analyse

An intimate look at the life and music of modern pop’s most legendary figure, Taylor Swift, from leading music journalist Rob Sheffield.A cultural phenomenon. A worldwide obsession. An agent of emotional chaos. There’s no parallel to Taylor Swift in history: a teenage girl who turns into the world’s favorite pop star, songwriter, storyteller, guitar hero, live performer, changing how music is made and heard. An all-time great on the level of The Beatles, Prince, or David Bowie.Heartbreak Is the National Anthem: How Taylor Swift Reinvented Pop Music is the first book that goes deep on the musical and cultural impact of Taylor Swift. Nobody can tell the story like Rob Sheffield, the bestselling and award-winning author of Dreaming the Beatles, On Bowie, and Love Is a Mix Tape. The legendary Rolling Stone journalist is the writer who has chronicled Taylor for every step of her long career, from her early days to the Eras Tour. Sheffield gets ri

Control theory, an interdisciplinary concept dealing with the behaviour of dynamical systems, is an important but often overlooked aspect of physics. This is the first broad and complete treatment of the topic tailored for physicists, one which goes from the basics right through to the most recent advances. Simple examples develop a deep understanding and intuition for the systematic principles of control theory, beyond the recipes given in standard engineering-focused texts. Up-to-date coverage of control of networks and complex systems, and a thorough discussion of the fundamental limits of control, including the limitations placed by causality, information theory, and thermodynamics are included. In addition it explores important recent advances in stochastic thermodynamics on the thermodynamic costs of information processing and control. For all students of physics interested in control theory, this classroom-tested, comprehensive approach to the topic with online solutions and fur

In the international trade and development arena, new and developing economies have created a block that is known as BRICS - Brazil, Russia, India, China and South Africa. Initially conceived to drive global change through economic growth, the financial crisis and reversal of fortunes of the BRICS nations have raised questions about their ability to have an impact on the governance of global affairs. This book explores the role of law in various areas of BRICS cooperation including: trade, investment, competition, intellectual property, energy, consumer protection, financial services, space exploration and legal education. It not only covers the specifics of each of the BRICS nations in the selected areas, but also offers innovative and forward-looking perspectives on the BRICS cooperation and their contribution to the reform of the global governance networks. This is a unique reference book suitable for academics, government officials, legal practitioners, business executives, researc

Chromatic graph theory is a thriving area that uses various ideas of 'colouring' (of vertices, edges, and so on) to explore aspects of graph theory. It has links with other areas of mathematics, including topology, algebra and geometry, and is increasingly used in such areas as computer networks, where colouring algorithms form an important feature. While other books cover portions of the material, no other title has such a wide scope as this one, in which acknowledged international experts in the field provide a broad survey of the subject. All fifteen chapters have been carefully edited, with uniform notation and terminology applied throughout. Bjarne Toft (Odense, Denmark), widely recognized for his substantial contributions to the area, acted as academic consultant. The book serves as a valuable reference for researchers and graduate students in graph theory and combinatorics and as a useful introduction to the topic for mathematicians in related fields.

The Soviet Counterinsurgency in the Western Borderlands investigates the Soviet response to nationalist insurgencies that occurred between 1944 and 1953 in the regions the Soviet Union annexed after the Nazi-Soviet pact: Eastern Poland, Lithuania, Latvia, and Estonia. Based on new archival data, Alexander Statiev presents the first comprehensive study of Soviet counterinsurgency that ties together the security tools and populist policies intended to attract the local populations. The book traces the origins of the Soviet pacification doctrine and then presents a comparative analysis of the rural societies in Eastern Poland and the Baltic States on the eve of the Soviet invasion. This analysis is followed by a description of the anti-communist resistance movements. Subsequently, the author shows how ideology affected the Soviet pacification doctrine and examines the major means to enforce the doctrine: agrarian reforms, deportations, amnesties, informant networks, covert operations, and

Since the end of the Cold War, the operations of secret police informers have come under the media spotlight and it is now common knowledge that vast internal networks of spies in the Soviet Union and East Germany were directed by the Communist Party. By contrast, very little historical information has been available on the covert operations of the security services in Mao Zedong's China. However, as Michael Schoenhals reveals in this intriguing and sometimes sinister account, public security was a top priority for the founders of the People's Republic and agents were recruited from all levels of society to ferret out 'counter-revolutionaries'. On the basis of hitherto classified archival records, the book tells the story of a vast surveillance and control apparatus through a detailed examination of the cultivation and recruitment of agents, their training and their operational activities across a twenty-year period from 1949 to 1967.

This is the first authored book to be dedicated to the new field of directed algebraic topology that arose in the 1990s, in homotopy theory and in the theory of concurrent processes. Its general aim can be stated as 'modelling non-reversible phenomena' and its domain should be distinguished from that of classical algebraic topology by the principle that directed spaces have privileged directions and directed paths therein need not be reversible. Its homotopical tools (corresponding in the classical case to ordinary homotopies, fundamental group and fundamental groupoid) should be similarly 'non-reversible': directed homotopies, fundamental monoid and fundamental category. Homotopy constructions occur here in a directed version, which gives rise to new 'shapes', like directed cones and directed spheres. Applications will deal with domains where privileged directions appear, including rewrite systems, traffic networks and biological systems. The most developed examples can be found in th

Several problems plague contemporary thinking about governance. From the multiple definitions that are often vague and confusing, to the assumption that governance strategies, networks and markets represent attempts by weakening states to maintain control. Rethinking Governance questions this view and seeks to clarify how we understand governance. Arguing that it is best understood as 'the strategies used by governments to help govern', the authors counter the view that governments have been decentred. They show that far from receding, states are in fact enhancing their capacity to govern by developing closer ties with non-government sectors. Identifying five 'modes' of government (governance through hierarchy, persuasion, markets and contracts, community engagement, and network associations), Stephen Bell and Andrew Hindmoor use practical examples to explore the strengths and limitations of each. In so doing, they demonstrate how modern states are using a mixture of governance modes t

Wireless networks are under constant pressure to provide ever higher data rates to increasing numbers of users with greater reliability. Space-time processing technology, which uses multiple antennas and sophisticated signal processing techniques, is a powerful new tool for improving system performance. The technology already features in the UMTS and CDMA2000 mobile standards. This book is an accessible introduction to the theory of space-time wireless communications. The authors discuss the basics of space-time propagation, space-time channels, channel capacity, spatial diversity and space-time coding. They highlight important trade-offs in the design of practical systems and cover advanced topics such as space-time OFDM and spread-spectrum modulation, co-channel interference cancellation, and multiuser MIMO. The book is an ideal introduction to this rapidly growing field for graduate students taking courses on wireless communications and for practitioners in the wireless industry. Ho

Using a wide range of archival and written sources, Rudi Matthee considers the economic, social and political networks established between Iran, its neighbours and the world at large, through the prism of the late Safavid silk trade. In so doing, he demonstrates how silk, a resource crucial to state revenue and the only commodity to span Iran's entire economic activity, was integral to aspects of late Safavid society, including its approach to commerce, export routes and, importantly, to the political and economic problems which contributed to its collapse in the early 1700s. In a challenge to traditional scholarship, the author argues that despite the introduction of a maritime, western-dominated channel, Iran's traditional land-based silk export continued to expand right up to the end of the seventeenth century. The book makes a major theoretical contribution to the debates on the social and economic history of the pre-modern world.

The dynamic character of American industrialization produced imbalances between the supply of and demand for labor across cities and regions. This book describes how employers and job-seekers responded to these imbalances to create networks of labor market communication and assistance capable of mobilizing the massive redistribution of population that was essential to maintain the rapid pace of the nation's economic growth between the Civil War and World War I. It combines a detailed description of the emerging labor market institutions with a careful analysis of a variety of quantitative evidence to assess the broader economic implications for geographic wage convergence and for American economic growth. Despite an expansion in the geographic scope of labor markets at this time, the evidence suggests that labor market institutions reinforced regional divisions within the United States and left a lasting impact on the evolution of many other aspects of the employment relationship.

This textbook, available in two volumes, has been developed from a course taught at Harvard over the last decade. The course covers principally the theory and physical applications of linear algebra and of the calculus of several variables, particularly the exterior calculus. The authors adopt the 'spiral method' of teaching, covering the same topic several times at increasing levels of sophistication and range of application. Thus the reader develops a deep, intuitive understanding of the subject as a whole, and an appreciation of the natural progression of ideas. Topics covered include many items previously dealt with at a much more advanced level, such as algebraic topology (introduced via the analysis of electrical networks), exterior calculus, Lie derivatives, and star operators (which are applied to Maxwell's equations and optics). This then is a text which breaks new ground in presenting and applying sophisticated mathematics in an elementary setting. Any student, interpreted in

For better or for worse, in recent times the rapid growth of international economic exchange has changed our lives. But when did this process of globalization begin, and what effects did it have on economies and societies? Pim de Zwart and Jan Luiten van Zanden argue that the networks of trade established after the voyages of Columbus and Da Gama of the late fifteenth century had transformative effects inaugurating the first era of globalization. The global flows of ships, people, money and commodities between 1500 and 1800 were substantial, and the re-alignment of production and distribution resulting from these connections had important consequences for demography, well-being, state formation and the long-term economic growth prospects of the societies involved in the newly created global economy. Whether early globalization had benign or malignant effects differed by region, but the world economy as we now know it originated in these changes in the early modern period.

In this major new history of Muslim merchants and their trade links with China, John W. Chaffee uncovers 700 years of history, from the eighth century, when Muslim communities first established themselves in southeastern China, through the fourteenth century, when trade all but ceased. These were extraordinary and tumultuous times. Under the Song and the Mongols, the Muslim diaspora in China flourished as legal and economic ties were formalized. At other times the Muslim community suffered hostility and persecution. Chaffee shows how the policies of successive dynastic regimes in China combined with geopolitical developments across maritime Asia to affect the fortunes of Muslim communities. He explores social and cultural exchanges, and how connections were maintained through faith and a common acceptance of Muslim law. This ground breaking contribution to the history of Asia, the early Islamic world, and to maritime history explores the networks that helped to shape the pre-modern wor

Bryan Garner is the most trusted living usage expert of our day, and Garner's Modern English Usage is the preeminent guide to the effective use of the English language. With well over 6,000 entries on English grammar, syntax, word choice, punctuation, capitalization, spelling, and style, this book is adored by professional writers and general readers alike (David Foster Wallace famously wrote a 62-page review that appeared in his collectionConsider the Lobster, calling its author "a genius"). In this major update to a timeless classic, Bryan Garner has dramatically expanded coverage of international English usage, making it for the first time a guide not only to American English usage, but to English usage globally.This expansion is important because interest in the English language is greater than ever; English is the lingua franca not only of higher education and academia, but of science, business, computing, aviation, and, arguably, entertainment. It is the most common language worl

Information retrieval, IR, the science of extracting information from any potential source, can be viewed in a number of ways: logical, probabilistic and vector space models are some of the most important. In this book, the author, one of the leading researchers in the area, shows how these views can be reforged in the same framework used to formulate the general principles of quantum mechanics. All the usual quantum-mechanical notions have their IR-theoretic analogues, and the standard results can be applied to address problems in IR, such as pseudo-relevance feedback, relevance feedback and ostensive retrieval. The relation with quantum computing is also examined. To keep the book self-contained appendices with background material on physics and mathematics are included. Each chapter ends with bibliographic remarks that point to further reading. This is an important, ground-breaking book, with much new material, for all those working in IR, AI and natural language processing.

This book gives applications of the theory of process algebra, or Algebra of Communicating Processes (ACP), that is the study of concurrent or communicating processes studied using an algebraic framework. The approach is axiomatic; the authors consider structures that are some set of mostly equational axioms, which are equipped with several operators. Thus the term 'algebra' is used in the model-theoretic sense. The axiomatic approach enables one to organize the field of process theories. The theory is applied systematically to a number of situations, including systolic algorithms, semantics of an object-oriented language, and protocols. It will be welcomed by computer scientists working in parallel programming.

This new, thoroughly revised edition of the acclaimed Cambridge Encyclopedia of Language incorporates the major developments in language study which have taken place since the mid 1990s. Two main new areas have been added: the rise of electronic communication in all its current forms from email to texting, and the crisis affecting the world's languages, of which half are thought to be so seriously endangered that they will die out this century. • All language statistics have been updated, and additional information provided about their linguistic affiliation • All topics involving technology have been revised to take account of recent developments, notably in phonetics, language disability, and computing • Maps have been revised to include new countries or country names • Special attention has been paid to fast-moving areas such as language teaching and learning • The text design has been completely updated with many new illustrations throughout

Polynomial equations have been long studied, both theoretically and with a view to solving them. Until recently, manual computation was the only solution method and the theory was developed to accommodate it. With the advent of computers, the situation changed dramatically. Many classical results can be more usefully recast within a different framework which in turn lends itself to further theoretical development tuned to computation. This first book in a trilogy is devoted to the new approach. It is a handbook covering the classical theory of finding roots of a univariate polynomial, emphasising computational aspects, especially the representation and manipulation of algebraic numbers, enlarged by more recent representations like the Duval Model and the Thom Codification. Mora aims to show that solving a polynomial equation really means finding algorithms that help one manipulate roots rather than simply computing them; to that end he also surveys algorithms for factorizing univariate

Permutation group algorithms are one of the workhorses of symbolic algebra systems computing with groups. They played an indispensable role in the proof of many deep results, including the construction and study of sporadic finite simple groups. This book describes the theory behind permutation group algorithms, including developments based on the classification of finite simple groups. Rigorous complexity estimates, implementation hints, and advanced exercises are included throughout. The central theme is the description of nearly linear time algorithms, which are extremely fast both in terms of asymptotic analysis and of practical running time. A significant part of the permutation group library of the computational group algebra system GAP is based on nearly linear time algorithms. The book fills a significant gap in the symbolic computation literature. It is recommended for everyone interested in using computers in group theory, and is suitable for advanced graduate courses.

Legendary storyteller Stephen King goes deep into the well of his imagination in this spellbinding novel about a seventeen-year-old boy who inherits the keys to a parallel world where good and evil are at war, and the stakes could not be higher - for their world or ours. Charlie Reade looks like a regular high school kid, great at baseball and football, a decent student. But he carries a heavy load.His mom was killed in a hit-and-run accident when he was ten, and grief drove his dad to drink. Charlie learned how to take care of himself - and his dad. Then, when Charlie is seventeen, he meets Howard Bowditch, a recluse with a big dog in a big house at the top of a big hill.In the backyard is a locked shed from which strange sounds emerge, as if some creature is trying to escape. When Mr. Bowditch dies, he leaves Charlie the house, a massive amount of gold, a cassette tape telling a story that is impossible to believe, and a responsibility far too massive for a boy to shoulder.Because wi

In the thirteenth book in Stuart Gibbs's New York Times bestselling Spy School series, superspy middle schooler Ben Ripley goes off the grid to eliminate a cybersecurity threat. After a devious computer hacker pulls off the CIA's worst-case scenario, shutting down power networks all over the world, Ben and his fellow spies-in-training are forced to make a harrowing emergency landing of their plane in Indonesia. While chaos begins to erupt around the planet, Ben deduces that his team is closer to the mysterious hacker's base than anyone else. But with all computers and phones down, there's no way to communicate with anyone at the CIA. On their latest mission to save the world, Ben and his friends face a conniving villain, assassins, pirates, sharks, and very big lizards in the most remote--and deadly--location of any spy school yet!
