This is a fully revised and updated version of Hans van der Doel's Democracy and Welfare Economics. It presents the economic theory of political decision-making (otherwise knownn as new political economy, or public choice), providing students with an accessible and clear introduction to this important subject. The authors identify four different methods of decision-making by which the political process transforms the demands of individual citizens into government policy and public goods and services: negotiation, majority decision, representations and bureaucratic implementation. These are analysed, in turn, as independent decision-making models whose effectiveness is examined with reference to economic theory. A final chapter draws conclusions from this analysis, arguing that the size of the public sector is a result of forces that work in different directions at different stages of the political process.

The essential guide to protecting and managing the professional reputation of both yourself and your organization.In our modern landscape of social media, viral news stories and fake news, professional reputations can be far too easily dismantled and tarnished. But many senior leaders, entrepreneurs, politicians, talent managers and even in-house lawyers are unaware of the full scope of techniques, methods and precautions that can be taken to prevent, react to, and mitigate reputational crises.As the lines blur between traditional and social media while misinformation runs rampant, reputations have become both more precious and more fragile than ever. In Reputation Matters, Jonathan Coad draws upon his decades of expertise (both as one of the country’s leading media lawyers and as a highly-regarded editorial lawyer) to provide the essential guide to protecting and managing the professional reputation of both yourself and your organization. Passivity in the face of public criticism is o

Proof complexity is a rich subject drawing on methods from logic, combinatorics, algebra and computer science. This self-contained book presents the basic concepts, classical results, current state of the art and possible future directions in the field. It stresses a view of proof complexity as a whole entity rather than a collection of various topics held together loosely by a few notions, and it favors more generalizable statements. Lower bounds for lengths of proofs, often regarded as the key issue in proof complexity, are of course covered in detail. However, upper bounds are not neglected: this book also explores the relations between bounded arithmetic theories and proof systems and how they can be used to prove upper bounds on lengths of proofs and simulations among proof systems. It goes on to discuss topics that transcend specific proof systems, allowing for deeper understanding of the fundamental problems of the subject.

In this age of information overload, people use a variety of strategies to make choices about what to buy, how to spend their leisure time, and even whom to date. Recommender systems automate some of these strategies with the goal of providing affordable, personal, and high-quality recommendations. This book offers an overview of approaches to developing state-of-the-art recommender systems. The authors present current algorithmic approaches for generating personalized buying proposals, such as collaborative and content-based filtering, as well as more interactive and knowledge-based approaches. They also discuss how to measure the effectiveness of recommender systems and illustrate the methods with practical case studies. The final chapters cover emerging topics such as recommender systems in the social web and consumer buying behavior theory. Suitable for computer science researchers and students interested in getting an overview of the field, this book will also be useful for profes

This book presents an introduction to singular-perturbation problems, problems which depend on a parameter in such a way that solutions behave non-uniformly as the parameter tends toward some limiting value of interest. The author considers and solves a variety of problems, mostly for ordinary differential equations. He constructs (approximate) solutions for oscillation problems, using the methods of averaging and of multiple scales. For problems of the nonoscillatory type, where solutions exhibit 'fast dynamics' in a thin initial layer, he derives solutions using the O'Malley/Hoppensteadt method and the method of matched expansions. He obtains solutions for boundary-value problems, where solutions exhibit rapid variation in thin layers, using a multivariable method. After a suitable approximate solution is constructed, the author linearizes the problem about the proposed approximate solution, and, emphasizing the use of the Banach/Picard fixed-point theorem, presents a study of the li

The rapid development of the theories of Volterra integral and functional equations has been strongly promoted by their applications in physics, engineering and biology. This text shows that the theory of Volterra equations exhibits a rich variety of features not present in the theory of ordinary differential equations. The book is divided into three parts. The first considers linear theory and the second deals with quasilinear equations and existence problems for nonlinear equations, giving some general asymptotic results. Part III is devoted to frequency domain methods in the study of nonlinear equations. The entire text analyses n-dimensional rather than scalar equations, giving greater generality and wider applicability and facilitating generalizations to infinite-dimensional spaces. The book is generally self-contained and assumes only a basic knowledge of analysis. The many exercises illustrate the development of the theory and its applications, making this book accessible to res

Dental Functional Morphology offers an alternative to the received wisdom that teeth merely crush, cut, shear or grind food and shows how teeth adapt to diet. Providing an analysis of tooth action based on an understanding of how food particles break, it shows how tooth form from the earliest mammals to modern-day humans can be understood using very basic considerations about fracture. It outlines the theoretical basis step by step, explaining the factors governing tooth shape and size and provides an allometric analysis that will revolutionize attitudes to the evolution of the human face and the impact of cooked foods on our dentition. In addition, the basis of the mechanics behind the fracture of different types of food, and methods of measurement are given in an easy-to-use appendix. It will be an important sourcebook for physical anthropologists, dental and food scientists, palaeontologists and those interested in feeding ecology.

Now in paperback, Topology via Logic is an advanced textbook on topology for computer scientists. Based on a course given by the author to postgraduate students of computer science at Imperial College, it has three unusual features. First, the introduction is from the locale viewpoint, motivated by the logic of finite observations: this provides a more direct approach than the traditional one based on abstracting properties of open sets in the real line. Second, the methods of locale theory are freely exploited. Third, there is substantial discussion of some computer science applications. Although books on topology aimed at mathematics exist, no book has been written specifically for computer scientists. As computer scientists become more aware of the mathematical foundations of their discipline, it is appropriate that such topics are presented in a form of direct relevance and applicability. This book goes some way towards bridging the gap.

The intimate relationship between form and function inherent in the design of animals is perhaps nowhere more evident than in the musculoskeletal system. In the bones, cartilage, tendons, ligaments, and muscles of all vertebrates there is a graceful and efficient physical order. This book is about how function determines form. It addresses the role of mechanical factors in the development, adaptation, maintenance, ageing and repair of skeletal tissues. The authors refer to this process as mechanobiology and develop their theme within an evolutionary framework. They show how the normal development of skeletal tissues is influenced by mechanical stimulation beginning in the embryo and continuing throughout life into old age. They also show how degenerative disorders such as arthritis and osteoporosis are regulated by the same mechanical processes that influence development and growth. Skeletal Function and Form bridges important gaps among disciplines, providing a common ground for under

How do you predict the parameters of future solar cycles? What is the role of dynamo theory in the cyclic activity of the Sun and similar stars? And what are the implications of chaos theory for stellar cycles? This book answers these questions and offers a timely review of studies in the cyclic activity of the Sun and other stars. This authoritative reference shows the importance of reliable predictions of the parameters of future solar cycles, and carefully explains the methods currently used to determine these (with special reference to the maximum of cycle 22). Some of the latest research into solar cycles is clearly presented; this includes helioseismology, observations of the extended activity cycle and the polar fields reversal, and contributions from dynamo theory and chaos theory. For graduate students and researchers, this monograph provides a much-needed synthesis of our understanding of activity cycles in the Sun and other stars.

The design and analysis of geometric algorithms have seen remarkable growth in recent years, due to their application in, for example, computer vision, graphics, medical imaging and CAD. The goals of this book are twofold: first to provide a coherent and systematic treatment of the foundations; secondly to present algorithmic solutions that are amenable to rigorous analysis and are efficient in practical situations. When possible, the algorithms are presented in their most general d-dimensional setting. Specific developments are given for the 2- or 3-dimensional cases when this results in significant improvements. The presentation is confined to Euclidean affine geometry, though the authors indicate whenever the treatment can be extended to curves and surfaces. The prerequisites for using the book are few, which will make it ideal for teaching advanced undergraduate or beginning graduate courses in computational geometry.

This collection explains developments within Beckett studies and why he has emerged as one of the most iconic writers of the twentieth century. It also proposes a new interpretive framework that explores both the expanded canon, which has doubled the volume of his works in the last ten years, and the new methods used to approach it. This book covers all the most recent approaches to the Beckett study, such as archival research, queer theory, mathematical readings of literature, neuro-scientific approaches, translation studies, and disability studies. These new approaches are shown to be relevant and necessary to provide a renewed understanding of the lasting value of Beckett's works.

Technology companies claim to connect people through touchscreens, but by conflating physical contact with emotional sentiments, they displace the constructed aspects of devices and women and other oppressed individuals’ critiques of how such technologies function.Technology companies and device designers correlate touchscreens and online sites with physical contact and emotional sentiments, promising unmediated experiences in which the screen falls away in favor of visceral materiality and connections. While touchscreens are key elements of most people’s everyday lives, critical frameworks for understanding the embodied experiences of using them are wanting. In Touch Screen Theory, Michele White focuses on the relation between physically touching and emotionally feeling to recenter the bodies and identities that are empowered, produced, and displaced by these digital technologies and settings. Drawing on detailed cases and humanities methods, White shows how and why gender, race, and

Addressing the consequences of European slavery, colonialism, and neo-colonialism on African history, knowledge and its institutions, this innovative book applies autoethnography to the understanding of African knowledge systems. Considering the 'Self' and Yoruba Being (the individual and the collective) in the context of the African decolonial project, Falola strips away Eurocentric influences and interruptions from African epistemology. Avoiding colonial archival sources, it grounds itself in alternative archives created by memory, spoken words, images and photographs to look at the themes of politics, culture, nation, ethnicity, satire, poetics, magic, myth, metaphor, sculpture, textiles, hair and gender. Vividly illustrated in colour, it uses diverse and novel methods to access an African way of knowing. Exploring the different ways that a society understands and presents itself, this book highlights convergence, enmeshing private and public data to provide a comprehensive understa

Innovative and interdisciplinary in approach, this book explores the role of the mother tongue in second language learning. It brings together contributions from a diverse team of authors, to showcase a range of Francophone perspectives from the fields of linguistics, psychology, cross-cultural psychiatry, psychoanalysis, translation studies, literature, creative writing, the neurosciences, and more. The book introduces a major new concept: the (M)other tongue, and shows its relevance to language learning and pediatrics in a multicultural society. The first chapter explores this concept from different angles, and the subsequent chapters present a range of theoretical and practical perspectives, including counselling case studies, literary examples and creative plurilingual pedagogies, to highlight how this theory can inform practical approaches to language learning. Engaging and accessible, readers will find new ideas and methods to adopt to their own thinking and practices, whether th

Compliance, or the behavioral response to legal rules, has become an important topic for academics and practitioners. A large body of work exists that describes different influences on business compliance, but a fundamental challenge remains: how to measure compliance or noncompliance behavior itself? Without proper measurement, it's impossible to evaluate existing management and regulatory enforcement practices. Measuring Compliance provides the first comprehensive overview of different approaches that are or could be used to measure compliance by business organizations. The book addresses the strengths and weaknesses of various methods and offers both academics and practitioners guidance on which measures are best for different purposes. In addition to understanding the importance of measuring compliance and its potential negative effects in a variety of contexts, readers will learn how to collect data to answer different questions in the compliance domain, and how to offer suggestio

This book presents an integrated collection of representative approaches for scaling up machine learning and data mining methods on parallel and distributed computing platforms. Demand for parallelizing learning algorithms is highly task-specific: in some settings it is driven by the enormous dataset sizes, in others by model complexity or by real-time performance requirements. Making task-appropriate algorithm and platform choices for large-scale machine learning requires understanding the benefits, trade-offs and constraints of the available options. Solutions presented in the book cover a range of parallelization platforms from FPGAs and GPUs to multi-core systems and commodity clusters, concurrent programming frameworks including CUDA, MPI, MapReduce and DryadLINQ, and learning settings (supervised, unsupervised, semi-supervised and online learning). Extensive coverage of parallelization of boosted trees, SVMs, spectral clustering, belief propagation and other popular learning algo

Breast pathology is arguably considered the most challenging and controversial area of diagnostic pathology. Many gradations of normal, pre-cancerous, and cancerous conditions are often indistinguishable, making a clear-cut diagnosis very difficult and often a cause for intense debate. This latest book in the Cambridge Illustrated Surgical Pathology series comprehensively covers all methods utilized by pathologists to accurately diagnose diseases affecting the breast. Malignant tumors are the predominant focus, but a full spectrum of inflammatory disorders and hyperplasias is also covered in detail, and the book uniquely shows the progression of disease states from incipient to advanced. Findings are diagnosed not only through the light microscope but also through genetic, molecular, and immunologic modalities; the text additionally includes the interpretation of cytologic specimens as an important diagnostic modality in breast pathology. The book is highly illustrated, with more than

This book was originally published in 1965. Dr Maxwell relates the ideas being introduced into the teaching of elementary university and advanced school algebra to the topics and methods with which teachers and students are already familiar and which are treated in the author's Advanced Algebra, Part I. Dr Maxwell shows the student meeting modern algebra for the first time what it is all about and leads those who will be taking the subject further to a firm grasp of the details that will come later in their course. From a discussion of algebraic systems with a single operation, he introduces the idea of a group and goes on to survey other algebraic structures: vector spaces, fields and rings. The second section is on linear algebra, mainly in terms of matrices and the solution of linear equations. A final section introduces the reader to more advanced concepts, including eigenvectors and eigenvalues and their use for quadratic forms. There is a large number of examples, with answers.
