Introduction to Programming Concepts With Case Studies in Python

This interdisciplinary study establishes connections between divergent approaches to rationality in philosophy, social science, and literary studies. Livingston provides a broad survey of the basic assumptions and questions associated with concepts of rationality in philosophical accounts of action, in decision theory, and in the theory of rational choice. He gives examples of the ways in which rationality is involved in the writing and reading of literary works, ranging from Icelandic sagas to Beckett, Dreiser, Lem, Poe and Zola. Topics examined include the role of concepts of desire, intention, and planning in action explanations, the relation between cognition and motivation, the rationality of desire, atomic versus agential perspectives on rationality, the rationality of groups and institutions, and the question of the rationality of science.

The WTO intellectual property and services agreements (TRIPs and GATS) form the global legal framework in which governments now regulate trade in knowledge. This second edition analyses the provisions of the agreements and examines closely the thirteen years of implementation and revision. Gathering together the interpretations placed on the agreements by the WTO dispute settlement bodies, it reports on the initiatives taken by the members both to liberalise trade in knowledge and to shape international business regulation. Drawing on this, Christopher Arup assesses the future of the WTO as a global law-making institution. Three expanded case studies (legal services, genetic codes/essential medicines, and on-line media) illustrate the impact of the agreements and highlight the challenges faced by the WTO in reconciling free trade with social regulation.

Why do some political parties flourish, while others flounder? In this book, Meguid examines variation in the electoral trajectories of the new set of single-issue parties: green, radical right, and ethnoterritorial parties. Instead of being dictated by electoral institutions or the socioeconomic climate, as the dominant theories contend, the fortunes of these niche parties, she argues, are shaped by the strategic responses of mainstream parties. She advances a theory of party competition in which mainstream parties facing unequal competitors have access to a wider and more effective set of strategies than posited by standard spatial models. Combining statistical analyses with in-depth case studies from Western Europe, the book explores how and why established parties undermine niche parties or turn them into weapons against their mainstream party opponents. This study of competition between unequals thus provides broader insights into the nature and outcome of competition between poli

A good grasp of the theory of structures - the theoretical basis by which the strength, stiffness and stability of a building can be understood - is fundamental to structural engineers and architects. Yet most modern structural analysis and design is carried out by computer, with the user isolated from the processes in action. Plastic Design of Frames; Volume 1. Fundamentals provides a broad introduction to the mathematics behind a range of structural processes. Some of the techniques used in this book may be familiar to the reader, and some may not, but each of the topics examined will give the structural engineer valuable insight into the basis of the subject. This companion book Plastic Design of Frames; Volume 2. Applications provides additional advanced topics and case studies. This lucid second volume provides a valuable read for structural engineers and others who wish to deepen their knowledge of the structural analysis and design of buildings.

In this text, two of the world's leading experts in palynology and paleobotany provide a comprehensive account of the fate of land plants during the 'great extinction' about 65 million years ago. They describe how the time boundary between the Cretaceous and Paleogene Periods (the K–T boundary) is recognised in the geological record, and how fossil plants can be used to understand global events of that time. There are case studies from over 100 localities around the world, including North America, China, Russia and New Zealand. The book concludes with an evaluation of possible causes of the K–T boundary event and its effects on floras of the past and present. This book is written for researchers and students in paleontology, botany, geology and Earth history, and everyone who has been following the course of the extinction debate and the K–T boundary paradigm shift.

Successful product design and development requires the ability to take a concept and translate the technology into useful, patentable, commercial products. This book guides the reader through the practical aspects of the commercialization process of drug, diagnostic and device biomedical technology including market analysis, product development, intellectual property and regulatory constraints. Key issues are highlighted at each stage in the process, and case studies are used to provide practical examples. The book will provide a sound road map for those involved in the biotechnology industry to effectively plan the commercialization of profitable regulated medical products. It will also be suitable for a capstone design course in engineering and biotechnology, providing the student with the business acumen skills involved in product development.

In 11 lively chapters expert contributors build from pervious works on competency-based supervision to address concerns common to new supervisors and veterans alike. With a wide range of case studies

This book represents a comprehensive examination of interest-group politics in France. Rather than the narrow case studies usually employed to study group politics, the book focuses on the overall pattern of interaction between interest groups and government. Drawing upon extensive interviews with French interest-group leaders and politicians, Wilson examines the structures and methods of group politics, the perspectives and attitudes of group leaders, and the place of interest groups in the broader pattern of French politics. He concludes that neither of the two major conceptualizations of interest-group/government relations is adequate to explain group politics in France. He suggests that the French state is much more powerful than recognized by these or other models of interest-group politics. Political influence is difficult for groups to develop and, once achieved, is fleeting. Consequently, groups engage in a wide range of activities, some of which are pluralist, others corporati

If you need a book that relates the core principles of quantum mechanics to modern applications in engineering, physics, and nanotechnology, this is it. Students will appreciate the book's applied emphasis, which illustrates theoretical concepts with examples of nanostructured materials, optics, and semiconductor devices. The many worked examples and more than 160 homework problems help students to problem solve and to practise applications of theory. Without assuming a prior knowledge of high-level physics or classical mechanics, the text introduces Schrödinger's equation, operators, and approximation methods. Systems, including the hydrogen atom and crystalline materials, are analyzed in detail. More advanced subjects, such as density matrices, quantum optics, and quantum information, are also covered. Practical applications and algorithms for the computational analysis of simple structures make this an ideal introduction to quantum mechanics for students of engineering, physics, nan

Complexity theory is a central field of the theoretical foundations of computer science. It is concerned with the general study of the intrinsic complexity of computational tasks; that is, it addresses the question of what can be achieved within limited time (and/or with other limited natural computational resources). This book offers a conceptual perspective on complexity theory. It is intended to serve as an introduction for advanced undergraduate and graduate students, either as a textbook or for self-study. The book will also be useful to experts, since it provides expositions of the various sub-areas of complexity theory such as hardness amplification, pseudorandomness and probabilistic proof systems. In each case, the author starts by posing the intuitive questions that are addressed by the sub-area and then discusses the choices made in the actual formulation of these questions, the approaches that lead to the answers, and the ideas that are embedded in these answers.

A Handbook of Categorical Algebra is designed to give, in three volumes, a detailed account of what should be known by everybody working in, or using, category theory. As such it will be a unique reference. The volumes are written in sequence, with the first being essentially self-contained, and are accessible to graduate students with a good background in mathematics. Volume 1, which is devoted to general concepts, can be used for advanced undergraduate courses on category theory. After introducing the terminology and proving the fundamental results concerning limits, adjoint functors and Kan extensions, the categories of fractions are studied in detail; special consideration is paid to the case of localizations. The remainder of the first volume studies various 'refinements' of the fundamental concepts of category and functor.

In the effort towards sustainability, it has become increasingly important to develop conceptual frames to understand the dynamics of social and ecological systems. Drawing on complex systems theory, this book investigates how human societies deal with change in linked social-ecological systems, and build capacity to adapt to change. The concept of resilience is central in this context. Resilient social-ecological systems have the potential to sustain development by responding to and shaping change in a manner that does not lead to loss of future options. Resilient systems also provide capacity for renewal and innovation in the face of rapid transformation and crisis. The term navigating in the title is meant to capture this dynamic process. Case studies and examples from several geographic areas, cultures and resource types are included, merging forefront research from natural sciences, social sciences and the humanities into a common framework for new insights on sustainability.

This book addresses the needs of the undergraduate nurse by presenting a series of classic case studies in nursing, in the adult and elderly population. Each case follows a standardised layout for ease of reference and includes photographs or clear line diagrams where appropriate, to illustrate key points. Each case is also accompanied by timed, structured questions with comprehensive referenced model answers to enhance the book's utility as a self-assessment tool.

A mutualism is an interaction between individuals of two different species of organism in which both benefit from the association. With a focus on mutualisms between ants and aphids, coccids, membracids and lycaenids, this volume provides a detailed account of the many different facets of mutualisms. Mutualistic interactions not only affect the two partners, but can also have consequences for higher levels of organization. By linking theory to case studies, the authors present an integrated account of processes and patterns of mutualistic interactions at different levels of organisation, from individuals to communities to ecosystems. Interactions between ants and their insect partners and their outcomes are explained from a resource-based, cost-benefit perspective. Covering a fascinating and growing subject in modern ecology, this book will be of interest to community and evolutionary ecologists and entomologists, at both research and graduate student level.

Principles of Metamorphic Petrology provides an introduction to ideas, techniques and approaches in the study of metamorphic rocks. The book begins with basic concepts, but advances further than most other metamorphic petrology texts. Examples of this include the latest chemographic approaches, the correct use of pseudosections and the application of x-ray compositional mapping to metamorphic problems. It also covers advances in thermobarometry and the application of modern geochronological techniques to the absolute timing of tectonometamorphic events. Determination of parent rocks is covered in detail and there is a modern exposition of partial melting reactions, melt extraction and deformation of migmatites. The book includes a large number of references to lead students into independent investigation. A valuable text for advanced undergraduate and graduate courses in metamorphic petrology, that serves as a reference for researchers and exploration geologists.

Depression is one of the most common mental health problems facing older people, and it is often unrecognised and usually under-treated. Integrated Management of Depression in the Elderly provides an entirely new approach to understanding late-life depression, by using a series of case studies with commentaries from practitioners internationally. The book covers the epidemiology, presentation and diagnosis of depression in older people and outlines current evidence for effective management drawing on recently published work. The substantive part of the book presents ten case studies of increasing complexity, each case has a commentary from a primary care clinician and a health or social care professional, to outline how professionals should work together to manage the patient within their community. Contributions from world experts give the book an international appeal. It will appeal to a wide audience of health and social care professionals together with psychiatrists-in-training.

A ground-breaking edited collection charting the rise and fall of forms of unfree labour in the ancient Mediterranean and in the modern Atlantic, employing the methodology of comparative history. The eleven chapters in the book deal with conceptual issues and different approaches to historical comparison, and include specific case-studies ranging from the ancient forms of slavery of classical Greece and of the Roman empire to the modern examples of slavery that characterised the Caribbean, Latin America and the United States. The results demonstrate both how much the modern world has inherited from the ancient in regard to ideology and practice of slavery; and also how many of the issues and problems related to the latter seem to have been fundamentally similar across time and space.

The study of translation is constantly expanding in a world that is experiencing a flourish of translated texts unparalleled in human history. Courses on translation, theory of translation and translation studies are being introduced at university level all over the world. This book provides a panorama of the many ways in which the complex phenomenon of translation is analysed. The contributions to this volume, by a group of leading international scholars, include traditional and new approaches in an interdisciplinary perspective and are representative of the multiplicity of approaches to translation studies, from the literary, to the linguistic, from the cognitive to the cross-cultural, from the descriptive to the applied and to the psychoanalytical. The range of topics covered and the exhaustive bibliography make this book a useful introduction but also provide new and stimulating readings for those already acquainted with the discipline.

This inter-disciplinary guide to the thermodynamics of living organisms has been thoroughly revised and updated to provide a uniquely integrated overview of the subject. Retaining its highly readable style, it will serve as an introduction to the study of energy transformation in the life sciences and particularly as an accessible means for biology, biochemistry and bioengineering undergraduate students to acquaint themselves with the physical dimension of their subject. The emphasis throughout the text is on understanding basic concepts and developing problem-solving skills. The mathematical difficulty increases gradually by chapter, but no calculus is required. Topics covered include energy and its transformation, the First Law of Thermodynamics, Gibbs free energy, statistical thermodynamics, binding equilibria and reaction kinetics. Each chapter comprises numerous illustrative examples taken from different areas of biochemistry, as well as a broad range of exercises and references f

The fifth volume of this definitive edition centres around Newton's Lucasian lectures on algebra, purportedly delivered during 1673–83, and subsequently prepared for publication under the title Arithmetica Universalis many years later. Dr Whiteside first reproduces the text of the lectures deposited by Newton in the Cambridge University Library about 1684. In these much reworked, not quite finished, professional lectiones, Newton builds upon his earlier studies of the fundamentals of algebra and its application to the theory and construction of equations, developing new techniques for the factorizing of algebraic quantities and the delimitation of bounds to the number and location of roots, with a wealth of worked arithmetical, geometrical, mechanical and astronomical problems. An historical introduction traces what is known of the background to the parent manuscript and assesses the subsequent impact of the edition prepared by Whiston about 1705 and the revised version published by Ne

This practical guide to survival data and its analysis for readers with a minimal background in statistics shows why the analytic methods work and how to effectively analyze and interpret epidemiologic and medical survival data with the help of modern computer systems. The introduction presents a review of a variety of statistical methods that are not only key elements of survival analysis but are also central to statistical analysis in general. Techniques such as statistical tests, transformations, confidence intervals, and analytic modeling are presented in the context of survival data but are, in fact, statistical tools that apply to understanding the analysis of many kinds of data. Similarly, discussions of such statistical concepts as bias, confounding, independence, and interaction are presented in the context of survival analysis and also are basic components of a broad range of applications. These topics make up essentially a 'second-year', one-semester biostatistics course in

After the Reformation, England's Catholics were marginalised and excluded from using printed media for propagandist ends. Instead, they turned to oral media, such as ballads and stories, to plead their case and maintain contact with their community. Building on the growing interest in Catholic literature which has developed in early modern studies, Alison Shell examines the relationship between Catholicism and oral culture from the mid-sixteenth to the eighteenth centuries. In order to recover the textual traces of this minority culture, she expands canonical boundaries, looking at anecdotes, spells and popular verse alongside more conventionally literary material. In her archival research she uncovers many important manuscript sources. This book is an important contribution to the rediscovery of the writings and culture of the Catholic community and will be of great interest to scholars of early modern literature, history and theology.

Temperate-zone forests have been shaped by fire, wind and grazing over thousands of years. This book provides a major contribution to the study of their dynamics by considering three important themes: • The combined influence of wind, fire and herbivory on the successional trajectories and structural characteristics of forests • The interaction of deciduous and evergreen tree species to form mosaics which, in turn, influence the environment and disturbance regime • The significance of temporal and spatial scale with regard to the overall impact of disturbances These themes are explored via case studies from the forests in the Lake States of the USA (Minnesota, Wisconsin and Michigan) where the presence of large primary forest remnants provides a unique opportunity to study the long-term dynamics of near-boreal, pine and hardwood-hemlock forests. The comparability of these forests to forests in other temperate zones allows generalizations to be made that may apply more widely.

This book attempts to uncover the basic form and structure of the Babylonian Talmud, which is a centrally important text in Jewish studies. The contribution made by Dr Jacobs to the study of the Talmud consists in his presentation of the literary principles employed in its composition, and he here presents a clear survey indicating the manner in which earlier material was reworked in order to make each component, or sugya, into a carefully structured and self-consistent unit. Jacobs compares the editors' methods in this regard with the manner in which Shakespeare converted the variety of chronicles and source material available to him into a much more dramatic literary form, which - while preserving the kernel of the story - completely transformed its character and impact. Dr Jacobs' study constitutes an excellent introduction to the Babylonian Talmud and to the nature of rabbinic thinking.

This text allows instructors to teach a course on heat and mass transfer that will equip students with the pragmatic, applied skills required by the modern chemical industry. This new approach is a combined presentation of heat and mass transfer, maintaining mathematical rigor while keeping mathematical analysis to a minimum. This allows students to develop a strong conceptual understanding, and teaches them how to become proficient in engineering analysis of mass contactors and heat exchangers and the transport theory used as a basis for determining how critical coefficients depend upon physical properties and fluid motions. Students will first study the engineering analysis and design of equipment important in experiments and for the processing of material at the commercial scale. The second part of the book presents the fundamentals of transport phenomena relevant to these applications. A complete teaching package includes a comprehensive instructor's guide, exercises, case studies,

The second volume of Dr Whiteside's annotated edition of all the known mathematical papers of Isaac Newton covers the period 1667–70. It is divided into three parts: Part 1 contains the first drafts of an attempted classification of cubics, together with more general studies on the properties of higher algebraic curves and researches into the 'organic' construction of curves. Part 2 comprises papers on miscellaneous researches in calculus, including the important De Analysi which introduced Newton to John Collins and others outside Cambridge; Newton's original text is here accompanied by Leibniz's excerpts and review, and by Newton's counter review. Part 3 contains Mercator's Latin translation of Kinckhuysen's introduction to algebra, with Newton's corrections and 'observations' upon it, and an account of researches into algebraic equations and their geometrical construction.

A robot manipulator is a movable chain of links interconnected by joints. One end is fixed to the ground, and a hand or end effector that can move freely in space is attached at the other end. This book begins with an introduction to the subject of robot manipulators. Next, it describes in detail a forward and reverse analysis for serial robot arms. Most of the text focuses on closed form solution techniques applied to a broad range of manipulator geometries, from typical industrial robot designs (relatively simple geometries) to the most complicated case of seven general links serially connected by six revolute joints. A unique feature is its detailed analysis of 6R-P and 7R mechanisms. Case studies show how the techniques described in the book are used in real engineering applications. The book will be useful to both graduate students and engineers working in the field of robotics.

This monograph is concerned with the qualitative theory of best L1-approximation from finite-dimensional subspaces. It presents a survey of recent research that extends 'classical' results concerned with best uniform approximation to the L1 case. The work is organized in such a way as to be useful for self-study or as a text for advanced courses. It begins with a basic introduction to the concepts of approximation theory before addressing one- or two-sided best approximation from finite-dimensional subspaces and approaches to the computation of these. At the end of each chapter is a series of exercises; these give the reader an opportunity to test understanding and also contain some theoretical digressions and extensions of the text.

In this book Warren Motley offers an original interpretation of James Fenimore Cooper's career. Whereas most studies of Cooper have centered on the figure of the Leatherstocking - that solitary model of the self-sufficient American hero untrammeled by civilization - this book examines Cooper's interest in the pioneer patriarchs who built new societies in the wilderness. Throughout his career Cooper explored an essential American problem: how to achieve the right balance between freedom and authority. He did this by retelling the story of the frontier settlement and thereby assessing its successes and failures. Like other writers in the decades before the Civil War, Cooper struggled with the legacy of the Revolutionary fathers - a legacy made more personal in Cooper's case by his father's role as a frontier land developer, judge, and Federalist politician. This book breaks new ground by relating Cooper's artistic development, and his ideas about authority in society, to his efforts to b

This 1996 book is a reliable account of the statistical framework for pattern recognition and machine learning. With unparalleled coverage and a wealth of case-studies this book gives valuable insight into both the theory and the enormously diverse applications (which can be found in remote sensing, astrophysics, engineering and medicine, for example). So that readers can develop their skills and understanding, many of the real data sets used in the book are available from the author's website: www.stats.ox.ac.uk/～ripley/PRbook/. For the same reason, many examples are included to illustrate real problems in pattern recognition. Unifying principles are highlighted, and the author gives an overview of the state of the subject, making the book valuable to experienced researchers in statistics, machine learning/artificial intelligence and engineering. The clear writing style means that the book is also a superb introduction for non-specialists.

This self-contained 2007 textbook presents an exposition of the well-known classical two-dimensional geometries, such as Euclidean, spherical, hyperbolic, and the locally Euclidean torus, and introduces the basic concepts of Euler numbers for topological triangulations, and Riemannian metrics. The careful discussion of these classical examples provides students with an introduction to the more general theory of curved spaces developed later in the book, as represented by embedded surfaces in Euclidean 3-space, and their generalization to abstract surfaces equipped with Riemannian metrics. Themes running throughout include those of geodesic curves, polygonal approximations to triangulations, Gaussian curvature, and the link to topology provided by the Gauss-Bonnet theorem. Numerous diagrams help bring the key points to life and helpful examples and exercises are included to aid understanding. Throughout the emphasis is placed on explicit proofs, making this text ideal for any student wi

This 1987 second volume of the Mechanical Universe studies electricity and magnetism, their relation to each other and light, and shows how the problem of light led to the special theory of relativity. Then, it moves on to modern physics, where particles may behave like waves and where some of the great verities of Newtonian physics appear less certain. Along with the first volume, this book is based on, though independent of, a public television series broadcast in the United States. Physics is presented as a human endeavor, with historical development forming a thread throughout the text. The prerequisites are minimal, only basic algebra and trigonometry since the necessary calculus is developed in the text, with physics providing the motivation. New concepts are introduced at the natural, logical point with many historical references to place physics in a social perspective. Many topics from twentieth-century physics are included. The book is attractively illustrated and will be a s

This book reviews and interrelates a large number of theoretical and experimental contributions to the research on finite plastic deformation of single crystals and polycrystalline metals. An overall theoretical framework for investigation of large strains in crystalline materials is presented that enables the blending of contemporary and earlier experimental research with modern concepts in solid mechanics. Professor Havner has provided a historical perspective throughout, including accurate attribution of ideas and emphasis on pioneering studies, beginning with G. I. Taylor and the German researchers in the 1920s. Early chapters deal with single crystals, including extensive analyses of particular experimental configurations. Then connections between single crystals and polycrystalline material behaviour are considered. Necessary background to the most general theoretical sections is presented in an appendix and approximately 200 references to the primary scientific literature are in

This innovative physics textbook intended for science and engineering majors develops classical mechanics from a historical perspective. The presentation of the standard course material includes a discussion of the thought processes of the discoverers and a description of the methods by which they arrived at their theories. However the presentation proceeds logically rather than strictly chronologically, so new concepts are introduced at the natural moment. The book assumes a familiarity with calculus, includes a discussion of rigid body motion, and contains numerous thought-provoking problems. It is largely based in content on The Mechanical Universe: Introduction to Mechanics and Heat, a book designed in conjunction with a tele-course to be offered by PBS in the Fall of 1985. The advanced edition, however, does not coincide exactly with the video lessons, contains additional material, and develops the fundamental ideas introduced in the lower-level edition to a greater degree.

This unique book explores both theoretical and experimental aspects of nonlinear vibrations and stability of shells and plates. It is ideal for researchers, professionals, students, and instructors. Expert researchers will find the most recent progresses in nonlinear vibrations and stability of shells and plates, including advanced problems of shells with fluid-structure interaction. Professionals will find many practical concepts, diagrams, and numerical results, useful for the design of shells and plates made of traditional and advanced materials. They will be able to understand complex phenomena such as dynamic instability, bifurcations, and chaos, without needing an extensive mathematical background. Graduate students will find (i) a complete text on nonlinear mechanics of shells and plates, collecting almost all the available theories in a simple form, (ii) an introduction to nonlinear dynamics, and (iii) the state of art on the nonlinear vibrations and stability of shells and pla

The Bhagavadgita is one of the most renowned texts of Hinduism because it contains discussions of important issues such as liberation and the nature of action as well as the revelation of the Krishna as the highest god and creator of the universe. It is included in the ancient Indian Mahabharata epic at one of its most dramatic moments, that is, when the final battle is about to begin. In contrast to many other studies, this book deals with the relationship between the Bhagavadgita and its epic contexts. On the basis of a thorough analysis of the text Angelika Malinar argues that its theology delineates not only new philosophical concepts and religious practices but also addresses the problem of righteous kingship and appropriate use of power. Malinar concludes by considering the Bhagavadgita's historical and cultural contexts and those features of the text that became paradigmatic in later Hindu religious traditions.

The dictionary definition of tradition refers to beliefs and practices that have been transmitted from generation to generation, however, 'tradition' can rest simply on the claim that certain cultural elements are rooted in the past. Claim and documented historical reality need not overlap. In the domain of religion, historically verifiable traditions coexist with recent innovations whose origins are spuriously projected back into time. This book examines the phenomenon of 'invented traditions' in religions ranging in time from Zoroastrianism to Scientology, and geographically from Tibet to North America and Europe. The various contributions, together with an introduction that surveys the field, use individual case studies to address questions such as the rationale for creating historical tradition for one's doctrines and rituals; the mechanisms by which hitherto unknown texts can enter an existing corpus; and issues of acceptance and scepticism in the reception of dubious texts.
