Soft Computing Based Modeling in Intelligent Systems

The study of human intelligence features many points of consensus, but there are also many different perspectives. In this unique book Robert J. Sternberg invites the nineteen most highly cited psychological scientists in the leading textbooks on human intelligence to share their research programs and findings. Each chapter answers a standardized set of questions on the measurement, investigation, and development of intelligence - and the outcome represents a wide range of substantive and methodological emphases including psychometric, cognitive, expertise-based, developmental, neuropsychological, genetic, cultural, systems, and group-difference approaches. This is an exciting and valuable course book for upper-level students to learn from the originators of the key contemporary ideas in intelligence research about how they think about their work and about the field.

The First World War had profound consequences both for the evolution of the international system and for domestic political systems. How and why did the war start? Offering a unique interdisciplinary perspective, this volume brings together a distinguished group of diplomatic historians and international relations scholars to debate the causes of the war. Organized around several theoretically based questions, it shows how power, alliances, historical rivalries, militarism, nationalism, public opinion, internal politics, and powerful personalities shaped decision-making in each of the major countries in the lead up to war. The emphasis on the interplay of theory and history is a significant contribution to the dialogue between historians and political scientists, and will contribute to a better understanding of the war in both disciplines.

Elizabeth Fry (née Gurney, 1780–1845) was descended from two wealthy Quaker banking families. Her Quaker faith was crucial to her adult life and she became active in social reform. Despite having eleven children, she was active in community work, and became a Quaker minister. Persuaded to visit the women's wing in Newgate Prison in 1813, she was appalled at the conditions in which the prisoners, and their children, lived. She became a pioneer in seeking to improve the situation for women in prisons and on transportation ships. The British Ladies' Society for Promoting the Reformation of Female Prisoners was probably the first national British women's society. Fry's ideas on the humane treatment of prisoners influenced international legal systems. This memoir, based on her letters and diaries, was edited by two of her daughters, and was first published in 1847.

This authoritative guide is the first to provide a complete system design perspective based on existing international standards and state-of-the-art networking and infrastructure technologies, from theoretical analyses to practical design considerations. The four most critical components involved in a multimedia networking system - data compression, quality of service (QoS), communication protocols, and effective digital rights management - are intensively addressed. Many real-world commercial systems and prototypes are also introduced, as are software samples and integration examples, allowing readers to understand practical tradeoffs in the design of multimedia architectures, and get hands-on experience learning the methodologies and procedures. Balancing just the right amount of theory with practical design and integration knowledge, this book is ideal for graduate students and researchers in electrical engineering and computer science, and also for practitioners in the communicatio

Unlike existing texts, this book blends for the first time three topics in physics - symmetry, condensed matter physics and computational methods - into one pedagogical textbook. It includes new concepts in mathematical crystallography; experimental methods capitalizing on symmetry aspects; non-conventional applications such as Fourier crystallography, color groups, quasicrystals and incommensurate systems; as well as concepts and techniques behind the Landau theory of phase transitions. Adopting a computational approach to the application of group theoretical techniques to solving symmetry related problems, it dramatically alleviates the need for intensive calculations usually found in the presentation of symmetry. Writing computer programs helps the student achieve a firm understanding of the underlying concepts, and sample programs, based on Mathematica, are presented throughout the book. Containing over 150 exercises, this textbook is ideal for graduate students in condensed matter

This study demonstrates that in a time of massive change characterized by the emergence of entirely new political systems and a fundamental reorganization of economic life, systematic patterns of economic conditions affecting election results at the aggregate level can in fact be identified during the first decade of post-communist elections in five post-communist countries: Russia, Poland, Hungary, Slovakia, and the Czech Republic. A variety of theoretical arguments concerning the conditions in which these effects are more or less likely to be present are also proposed and tested. Analysis is conducted using an original data set of regional level economic, demographic, and electoral indicators, and features both broadly based comparative assessments of the findings across all twenty elections as well as more focused case study analyses of pairs of individual elections.

All civilisations, ancient and modern, are founded on agriculture. In this fascinating account of one of the most fundamental aspects of humankind's march from prehistory to the present day, the author considers the evidence for the origins and evolution of agriculture in various parts of the world; a balanced view is presented based on the archaeology, botany, genetics, ecology and anthropology of domesticates and their wild relatives. The basic agricultural systems which emerged from areas yielding traces of the earliest plant and animal domestication are described, and their drastic modification in recent times is considered. In a concluding chapter the present situation is reviewed, and the possible risks of a system which now relies on a relatively small number of species to supply the majority of our food are discussed.

In South America indigenous languages are extremely diverse. There are over one hundred language families in this region alone. Contributors from around the world explore the history and structure of these languages, combining insights from archaeology and genetics with innovative linguistic analysis. The book aims to uncover regional patterns and potential deeper genealogical relations between the languages. Based on a large-scale database of features from sixty languages, the book analyses major language families such as Tupian and Arawakan, as well as the Quechua/Aymara complex in the Andes, the Isthmo-Colombian region and the Andean foothills. It explores the effects of historical change in different grammatical systems and fills gaps in the World Atlas of Language Structures (WALS) database, where South American languages are underrepresented. An important resource for students and researchers interested in linguistics, anthropology and language evolution.

Positions of authority in any society are limited in number, and therefore rules of selection must operate in their recruitment. There must also be limitations upon the range of authority exercised. These problems are particularly acute in the case of high office, where the questions of recruitment and succession are of central importance. This 1979 volume provides a general and theoretical analysis of succession in different traditional African societies. Jack Goody's introduction spells out the main ways in which systems of succession to office differ, and assesses the problem each system solves and the dilemmas it creates. He also analyses the tensions to which succession gives rise, and relates these to specific methods of transferring office from one generation to the next, The four case studies, all based on extensive fieldwork, consider succession among the Bausto, the Baganda, the Nyamwezi and the Gonja.

This book explains why contemporary liberal democracies are based on historical templates rather than revolutionary reforms; why the transition in Europe occurred during a relatively short period in the nineteenth century; why politically and economically powerful men and women voluntarily supported such reforms; how interests, ideas, and pre-existing institutions affected the reforms adopted; and why the countries that liberalized their political systems also produced the Industrial Revolution. The analysis is organized in three parts. The first part develops new rational choice models of (1) governance, (2) the balance of authority between parliaments and kings, (3) constitutional exchange, and (4) suffrage reform. The second part provides historical overviews and detailed constitutional histories of six important countries. The third part provides additional evidence in support of the theory, summarizes the results, contrasts the approach taken in this book with that of other schola

Originally published in 1970, this is a descriptive linguistic analysis of the grammar of modern Igbo. The analysis, based primarily on material gathered from two native speakers, one from Owerri Province and the other from Umuahia Province, is presented in the framework of the transformational model developed by Noam Chomsky. The grammar is a practical attempt to apply some of the advances in theoretical linguistics to a little-known language. There is no other grammar of Igbo in existence which presents a comprehensive descriptive analysis of the underlying and surface systems of the syntax and phonology of the language. The book will be useful for linguists as an example of the application of the transformational model to an exotic language. It will be of interest to specialists in African studies for the insights gained and the data presented from an important African language.

The recognition of the profound impact of corporations on the economies and societies of all countries of the world has focused attention on the growing importance of corporate governance. There is an ongoing diversity of corporate governance systems, based on historical cultural and institutional differences that involve different approaches to the values and objectives of business activity. Sound corporate governance is universally recognised as essential to market integrity and efficiency, providing a vital underpinning for financial stability and economic growth. As the adequacy of the existing dominant paradigms of corporate governance are increasingly challenged, the search for coherent new paradigms is a vital task for corporate governance in the future.

Hankel operators are of wide application in mathematics (functional analysis, operator theory, approximation theory) and engineering (control theory, systems analysis) and this account of them is both elementary and rigorous. The book is based on graduate lectures given to an audience of mathematicians and control engineers, but to make it reasonably self-contained, the author has included several appendices on mathematical topics unlikely to be met by undergraduate engineers. The main prerequisites are basic complex analysis and some functional analysis, but the presentation is kept straightforward, avoiding unnecessary technicalities so that the fundamental results and their applications are evident. Some 45 exercises are included.

Based on extensive empirical research, this groundbreaking book describes and analyses existing systems for enforcing sentences of imprisonment imposed by international criminal courts and makes recommendations for the strategic and structural development of the international penal system. In particular, it advocates a resocialisation-focused international penal policy delivered using restorative justice modalities post-conviction and the creation of an accountable international prison system. Singly or combined, these developments will contribute to the institutionalisation of the international penal system and enhance the international nature of the sanction, the international control over the way international punishment is enforced and the equal treatment of international prisoners. These developments will also help to ensure that international punishment is principled and progressive and implemented in a humane and effective system.

The first textbook on mathematical methods focusing on techniques for optical science and engineering, this text is ideal for upper division undergraduate and graduate students in optical physics. Containing detailed sections on the basic theory, the textbook places strong emphasis on connecting the abstract mathematical concepts to the optical systems to which they are applied. It covers many topics which usually only appear in more specialized books, such as Zernike polynomials, wavelet and fractional Fourier transforms, vector spherical harmonics, the z-transform, and the angular spectrum representation. Most chapters end by showing how the techniques covered can be used to solve an optical problem. Essay problems based on research publications and numerous exercises help to further strengthen the connection between the theory and its applications.

Although China’s economy is one of the largest in the world, Western understanding of it is often based on dated assumptions and incomplete information.In The New China Playbook, Keyu Jin burrows deep into the mechanisms of a unique system, taking a nuanced, clear-eyed, and data-based look inside. From the far-reaching and unexpected consequences of China’s one-child policy to the government’s complex relationship with entrepreneurs, from its boisterous financial system to its latest push for technological innovation, Jin reveals the frequently misunderstood dynamics at play.China is entering a new era, soon to be shaped by a radically different younger generation. As it strives to move beyond the confines of conventional socialism stained by shortages and capitalism hindered by inequality, the world is about to witness the emergence of a completely new dynamic between two diametrically opposite systems. The thorough understanding of China’s playbook that Jin provides will be essential

This book is concerned with techniques for formal theorem-proving, with particular reference to Cambridge LCF (Logic for Computable Functions). Cambridge LCF is a computer program for reasoning about computation. It combines the methods of mathematical logic with domain theory, the basis of the denotational approach to specifying the meaning of program statements. Cambridge LCF is based on an earlier theorem-proving system, Edinburgh LCF, which introduced a design that gives the user flexibility to use and extend the system. A goal of this book is to explain the design, which has been adopted in several other systems. The book consists of two parts. Part I outlines the mathematical preliminaries, elementary logic and domain theory, and explains them at an intuitive level, giving reference to more advanced reading; Part II provides sufficient detail to serve as a reference manual for Cambridge LCF. It will also be a useful guide for implementors of other programs based on the LCF approa

Since the 1990s, mainstream political parties have failed to address the problem of growing inequality, resulting in political backlash and the transformation of European party systems. Most attempts to explain the rise of inequality in political science take a far too narrow approach, considering only economic inequality and failing to recognize how multiple manifestations of inequality combine to reinforce each other and the underlying political features of advanced welfare states. Combining training in public health with a background in political science, Julia Lynch brings a unique perspective to debates about inequality in political science and to public health thinking about the causes of and remedies for health inequalities. Based on case studies of efforts to reduce health inequalities in England, France and Finland, Lynch argues that inequality persists because political leaders chose to frame the issue of inequality in ways that made it harder to solve.

This book, first published in 2005, builds on institutionalist theory in both economics and political science to offer a general political economy framework for the study of welfare capitalism. Based on the key idea that social protection in a modern economy, both inside and outside the state, can be understood as protection of specific investments in human capital, the book offers a systematic explanation of popular preferences for redistributive spending, the economic role of political parties and electoral systems, and labor market stratification (including gender inequality). Contrary to the popular idea that competition in the global economy undermines international differences in the level of social protection, the book argues that these differences are made possible by a high international division of labor. Such a division is what allows firms to specialize in production that requires an abundant supply of workers with specific skills, and hence high demand for protection.

Based on university and industry courses developed by the author, this book reviews all the relevant research and technology to provide an introduction to the principles and applications of passive seismic monitoring. It integrates up-to-date case studies and interactive online exercises, making it a comprehensive and accessible resource for advanced students and researchers in geophysics and engineering, as well as industry

Nonlinear waves are pervasive in nature, but are often elusive when they are modelled and analysed. This book develops a natural approach to the problem based on phase modulation. It is both an elaboration of the use of phase modulation for the study of nonlinear waves and a compendium of background results in mathematics, such as Hamiltonian systems, symplectic geometry, conservation laws, Noether theory, Lagrangian field theory and analysis, all of which combine to generate the new theory of phase modulation. While the build-up of theory can be intensive, the resulting emergent partial differential equations are relatively simple. A key outcome of the theory is that the coefficients in the emergent modulation equations are universal and easy to calculate. This book gives several examples of the implications in the theory of fluid mechanics and points to a wide range of new applications.

This book, first published in 2000, is based on the modern conceptual understanding of crystal fields. It provides readers with clear instructions and a set of computer programs for the phenomenological analysis of energy spectra of magnetic ions in solids. The text clarifies several issues that have historically produced confusion in this area, particularly the effects of covalency and ligand polarization on the energy spectra of magnetic ions. Readers are shown how to employ a hierarchy of parametrized models to extract as much information as possible from observed lanthanide and actinide spectra. This book of crystal field theory describes all of the available phenomenological models, together with the conceptual and computational tools necessary for their use. It will be of particular interest to graduate students and researchers working in the development of opto-electronic systems and magnetic materials.

Concerns over environmental and human health impacts of conventional weed management practices, herbicide resistance in weeds, and rising costs of crop production and protection have led agricultural producers and scientists in many countries to seek strategies that take greater advantage of ecological processes and thereby allow a reduction in herbicide use. This book provides principles and practices for ecologically based weed management in a wide range of temperate and tropical farming systems. After examining weed life histories and processes determining the assembly of weed communities, the authors describe how tillage and cultivation practices, manipulations of soil conditions, competitive cultivars, crop diversification, grazing livestock, arthropod and microbial biocontrol agents, and other factors can be used to reduce weed germination, growth, competitive ability, reproduction and dispersal. Special attention is given to the evolutionary challenges that weeds pose and the ro
