This book gives an account of certain observed irregularities on the rotation of the Earth, both in its rate of rotation (giving a variable length of day) and in the position of its axis. These irregularities are caused by events on and within the Earth and provide a means of studying a number of geophysical problems. Seasonal shifts in air masses and variable winds are causes of short-period fluctuations in the rotation. Climatic changes and their attendant sea levels are in part responsible for long-term fluctuations. Modern observations of the Moon and descriptions of ancient elipses both establish a secular increase in the length of day. The interpretation involves atmospheric, oceanic and bodily tides. The book provides a unified treatment of the rotation of the Earth, making this method of studying geophysical phenomena more readily accessible to geophysicists and others.

Given its brevity, Plato's Meno covers an astonishingly wide array of topics: politics, education, virtue, definition, philosophical method, mathematics, the nature and acquisition of knowledge and immortality. Its treatment of these, though profound, is tantalisingly short, leaving the reader with many unresolved questions. This book confronts the dialogue's many enigmas and attempts to solve them in a way that is both lucid and sympathetic to Plato's philosophy. Reading the dialogue as a whole, it explains how different arguments are related to one another and how the interplay between characters is connected to the philosophical content of the work. In a new departure, this book's exploration focuses primarily on the content and coherence of the dialogue in its own right and not merely in the context of other dialogues, making it required reading for all students of Plato, be they from the world of classics or philosophy.

The first edition of Rock Mechanics and Engineering bridged the gap between scientific research on rock mechanics and practical engineering. It was resolutely aimed at giving practical information to geologists, engineering geologists and engineers. Emphasis was placed on the lessons to be learnt from the study of case histories, with the Malpasset Dam rupture and the large Vajont rock slide amongst those described. In this second, enlarged edition the author continues to emphasise aspects of rock mechanics. Modern efforts at establishing an engineering classification of rocks are summarised and considerable attention is given to the Austrian tunnelling method. Firm in his belief that there is no better way to study the subject than by the detailed analysis of case histories, Dr Jaeger has incorporated a number of new ones, for example the discussion on the engineering classification of jointed rock masses and the required rock support is illustrated by descriptions of the second Gotth

Originally published in 1953, this was the first edition of Dekker's plays to appear in print since the late nineteenth century. Thus, for many years prior, Dekker had been the least accessible of the prominent Elizabethan dramatists, with the result that his anthologized plays had received undue attention at the expense of other highly readable works of the second rank. Professor Fredson Bowers here presents a critical old-spelling text of the ordinarily accepted canon, together with a few works not collected previously but which seem to merit inclusion in an edition of Dekker's plays. The text of the complete plays is in four volumes and a complementary four-volume set contains detailed introductions and notes to all the plays. In a general textual introduction Professor Bowers sets forth a reasoned account of his editorial method and procedures for a critical edition according to bibliographical principles.

Mathematical modelling of physical and chemical systems is used extensively throughout science, engineering, and applied mathematics. To use mathematical models, one needs solutions to the model equations; this generally requires numerical methods. This book presents numerical methods and associated computer code in Matlab for the solution of a spectrum of models expressed as partial differential equations (PDEs). The authors focus on the method of lines (MOL), a well-established procedure for all major classes of PDEs, where the boundary value partial derivatives are approximated algebraically by finite differences. This reduces the PDEs to ordinary differential equations (ODEs) and makes the computer code easy to understand, implement, and modify. Also, the ODEs (via MOL) can be combined with any other ODEs that are part of the model (so that MOL naturally accommodates ODE/PDE models). This book uniquely includes a detailed line-by-line discussion of computer code related to the ass

The scope and treatment of Dr Maxwell's two-volume course covering the transition from school to university is directed towards training students in algebraic thinking, so that processes do not become too mechanical. The explanations are full, the difficulties of the beginner are foreseen and overcome. Indeed, the course should prove excellent for the lone student as well as for the supervised class. Topics in part one include polynomial theory, equations, inequalities, partial fractions, permutations and combinations, the binomial theorem and series and determinants. The 'feel' of the book may be illustrated by reference to the treatment of partial fractions, which is novel in several ways. A theoretical exposition is given in some detail and varies from standard treatments in leading to a method of calculation that arises directly from it. The book contains many 'drill' examples, which the author considers essential.

Thoughtful Foragers is about hunter-gatherer decision making. The author explores the implications of the human mind as a product of biological evolution for the way in which humans solve foraging problems. He draws on studies form ethology, psychology and ethnography prior to turning his attention to prehistoric hunter-gatherers. He attempts to construct explanations for patterns in the archaeological record by an explicit focus on decision making by individuals. Thoughtful Foragers will appeal to specialists in European prehistory as well as to those interested in archaeological theory and method. It makes some very significant advances, which will be of real importance for the field of evolutionary theory in relation to human evolution and the evaluation of human social systems.

In marked contrast with the anthropological and cross-cultural approaches that featured so prominently in archaeological research this contributory volume emphasises the archaeological significance of historical method and philosophy. Drawing particularly on the work of R. G. Collingwood, the contributors show that the notion of 'history seen from within' is a viable approach that can be applied in ethnoarchaeology and in both historic and prehistoric archaeology. There is a discussion of short, medium and long-term historical structures in relation to social events generating observed material culture patterning. Examination of the relationship between structure and event within historical contexts leads to insights into the interdependence of continuity and change, and into the nature of widely recognised processes such as acculturation, diffusion and migration.

The second edition of this standard text guides biomedical researchers in the selection and use of advanced statistical methods and the presentation of results to clinical colleagues. It assumes no knowledge of mathematics beyond high school level and is accessible to anyone with an introductory background in statistics. The Stata statistical software package is again used to perform the analyses, this time employing the much improved version 10 with its intuitive point and click as well as character-based commands. Topics covered include linear, logistic and Poisson regression, survival analysis, fixed-effects analysis of variance, and repeated-measure analysis of variance. Restricted cubic splines are used to model non-linear relationships. Each method is introduced in its simplest form and then extended to cover more complex situations. An appendix will help the reader select the most appropriate statistical methods for their data. The text makes extensive use of real data sets avai

The material has been tested by real students over many years so all the essentials are covered. With over 300 exercises to help you test your progress, you'll soon learn how to think like a mathematic

The problems which Christians faced in the second-century world, with its variety of religious beliefs, have a close relation to those which confront them today. The new religion was presented with a range of external threats and criticism which evoked a vigourous, fundamental and imaginative response. The arguments of this most creative period of Christian thought were of a more general and philosophical kind than the discussions of dogmatic issues in the fourth and fifth centuries, and are properly regarded as the beginning of Christian philosophy, though this does not of course imply the emergence of a 'system' or a uniformly philosophical level of writing. Professor Osborn's method in this book, derived from analytic philosophy, is to elucidate specific questions which occupied four major writers from different centres of early Christianity: Justin, Irenaeus, Tertullian and Clement of Alexandria. Is there one God and can one speak of him? Is man free and has he any link with God? W

Drawing from postliberal, revisionary and Latin American liberation theological perspectives, David Kamitsuka offers proposals on theological method and doctrine responsive to the intellectual, pastoral and socio-political challenges of contemporary culture. He recasts inter-movement polemics in order to forge a theological approach which promotes what are often considered to be competing values among these three theological movements: solidarity with the oppressed (liberationist), redescribing the Christian communal sense of scripture (postliberal), and fully critical reflection (revisionist). The author advocates an apologetic strategy entailing coherentist and consensus elements for justifying Christian claims in the pluralistic public realm. He provides a model for reading scripture theologically which addresses the challenges of poststructuralism and a globally diverse Church. Kamitsuka uses rule theory to adjudicate doctrinal disputes on the relationship between salvation and pol

The role of economics in urban conservation is relatively underdeveloped. Professor Lichfield has added to his other pioneering studies in this innovative and important exposition of approach, method and techniques for the systematic application of economics in the conservation of urban areas. In order to establish an appropriate base for the economic analysis and application in parts III, IV and V of the book, the opening sections provide essential background information about the management and planning for conservation in the urban system in general and examine the special place of the cultural built heritage: those building and objects chosen by society for particular protection. Written in a highly accessible style, Economics in Urban Conservation makes a major contribution to an understanding of how economics in conservation can help in achieving a sensible balance between continuity and change in the built environment.

This book is an authoritative description of the various approaches to and methods in the theory of irregularities of distribution. The subject is primarily concerned with number theory, but also borders on combinatorics and probability theory. The work is in three parts. The first is concerned with the classical problem, complemented where appropriate with more recent results. In the second part, the authors study generalizations of the classical problem, pioneered by Schmidt. Here, they include chapters on the integral equation method of Schmidt and the more recent Fourier transform technique. The final part is devoted to Roth's '1/4-theorem'.

The theory of Lie groups rests on three pillars: analysis, topology and algebra. Correspondingly it is possible to distinguish several phases, overlapping in some degree, in its development. It also allows one to regard the subject from different points of view, and it is the algebraic standpoint which has been chosen in this tract as the most suitable one for a first introduction to the subject. The aim has been to develop the beginnings of the theory of Lie groups, especially the fundamental theorems of Lie relating the group to its infinitesimal generators (the Lie algebra); this account occupies the first five chapters. Next to Lie's theorems in importance come the basic properties of subgroups and homomorphisms, and they form the content of Chapter VI. The final chapter, on the universal covering group, could perhaps be most easily dispensed with, but, it is hoped, justifies its existence by bringing back into circulation Schreier's elegant method of constructing covering groups.

Integration of differential equations is a central problem in mathematics and several approaches have been developed by studying analytic, algebraic, and algorithmic aspects of the subject. One of these is Differential Galois Theory, developed by Kolchin and his school, and another originates from the Soliton Theory and Inverse Spectral Transform method, which was born in the works of Kruskal, Zabusky, Gardner, Green and Miura. Many other approaches have also been developed, but there has so far been no intersection between them. This unique introduction to the subject finally brings them together, with the aim of initiating interaction and collaboration between these various mathematical communities. The collection includes a LMS Invited Lecture Course by Michael F. Singer, together with some shorter lecture courses and review articles, all based upon a mini-programme held at the International Centre for Mathematical Sciences (ICMS) in Edinburgh.

Multiple pregnancies are the most frequent and serious complication of assisted reproduction. Both high-order multiple and twin pregnancies entail a number of medical and economic outcomes that affect the children, the mother, the parents, the families, and society as a whole. Limiting the number of embryos to transfer is the only method available to decrease the incidence of multiple pregnancies. Single Embryo Transfer reviews the advantages and limitations of this approach to assisted reproduction. The crucial issue of selecting the best embryo will be reviewed in detail. All clinical issues involved in setting up and running an SET programme will be covered, including important topics such as cryopreservation of embryos, embryo donation, and patient counselling. The final chapters on future SET trends in Europe and North America are written by leading figures in the IVF world. The book is of interest to physicians, embryologists, nurses, insurers, politicians, ethicists and patients

Social network analysis maps relationships and transactions between people and groups. This text was the first book-length application of this method to the ancient world, using the abundant documentary evidence from sixth-century Oxyrhynchos and Aphrodito in Egypt. Professor Ruffini combines a prosopographical survey of both sites with computer analyses of the topographical and social networks in their papyri. He thereby uncovers hierarchical social structures in Oxyrhynchos not present in Aphrodito, and is able for the first time to trace the formation of the famous Apion estate. He can also use quantitative techniques to locate the central players in the Aphrodito social landscape, allowing us to see past the family of Dioskoros to discover the importance of otherwise unknown figures. He argues that the apparent social differences between Oxyrhynchos and Aphrodito in fact represent different levels of geographic scale, both present within the same social model.

The goal of this book is to provide a comprehensive and systematic introduction to the important and highly applicable method of data refinement and the simulation methods used for proving its correctness. The authors concentrate in the first part on the general principles needed to prove data refinement correct. They begin with an explanation of the fundamental notions, showing that data refinement proofs reduce to proving simulation. The book's second part contains a detailed survey of important methods in this field, which are carefully analysed, and shown to be either incomplete, with counterexamples to their application, or to be always applicable whenever data refinement holds. This is shown by proving, for the first time, that all these methods can be described and analysed in terms of two simple notions: forward and backward simulation. The book is self-contained, going from advanced undergraduate level and taking the reader to the state of the art in methods for proving simula

Latin paleography of the classical period and beyond the Carolingian era has been well studied and described. But from about 1100 onwards we find a period of increasing national divergence in the character of book-hands used for writing, formal MSS. In this book Professor Thomson provides 132 characteristic specimens of the period 1100–1500, reproduced by lithography (in all cases in the original size). He excludes curial or chancery hands. Opposite each plate is a transcription of several lines. Above this, Professor Thomson provides comments on the distinguishing characteristics of the script. Cumulatively, the effect of these analyses is to provide a method of dating late medieval MSS and ascribing them to their country of origin.

This volume examines the provision of primary medical care in twenty-three different, predominantly developed countries, selected because of their variety and importance. An analysis is made of the problems and fundamental requirements of primary care (known as general practice in many countries). Arguments are put forward on priorities of spending and allocation of resources. Reasons for failure in the provision of adequate medical care are advanced. The role of the medical profession in education and in the quality of advice it has given to governments throughout the world are examined. Who should provide primary care? How should doctors be paid? Does the method of payment influence the quality of treatment received by the patient? Are any general lessons to be drawn from particular countries that could be of help in others? These and other questions are examined and answered.

Coins are one of the most abundant sources for our study of the past, yet their value as historical evidence is relatively neglected because of a general lack of knowledge of numismatic techniques. This volume of essays, offered by a circle of friends, colleagues and pupils working in Britain, Europe and North America, is intended to pay tribute to Philip Grierson's unique contribution to the study of numismatic method. A medievalist by training, through his wide-ranging interests in coins and coinage Grierson has commanded the respect of historians and numismatists of all periods for the originality and good sense of his prolific scholarship. More than any other living scholar, he has been responsible for making available an understanding of numismatic expertise to specialist and non-specialist audiences.

This book presents a comprehensive treatment of basic mathematical logic. The author's aim is to make exact the vague, intuitive notions of natural number, preciseness, and correctness, and to invent a method whereby these notions can be communicated to others and stored in the memory. He adopts a symbolic language in which ideas about natural numbers can be stated precisely and meaningfully, and then investigates the properties and limitations of this language. The treatment of mathematical concepts in the main body of the text is rigorous, but, a section of 'historical remarks' traces the evolution of the ideas presented in each chapter. Sources of the original accounts of these developments are listed in the bibliography.

The first book covering EBG structures and their antenna applications, this provides a dynamic resource for engineers, and researchers and graduate students working in antennas, electromagnetics and microwaves.

This is the final volume of a series covering all stages of development of the Calculus, from the last year at school to degree standard. The books are written for students of science and engineering as well as for specialist mathematicians, and are designed to bridge the gap between the works used in schools and more advanced studies, with their emphasis on rigour. Dr Maxwell guides the student through the early stages of analysis, while keeping the exposition as clear and uncomplicated as possible. The aim is to instil a knowledge of general method rather than to study the particular functions in detail; in this way the student is led on naturally to apply what they have learnt to move advanced mathematical contexts. Dr Maxwell is, as usual, lucid in his presentation, explaining difficulties in greater detail than is customary in an advanced textbook, and guarding against the pitfalls that await the beginner.

T. M. Flett was a Professor of Pure Mathematics at the University of Sheffield from 1967 until his death in 1976. This book, which he had almost finished, has been edited for publication by Professor J. S. Pym. This text is a treatise on the differential calculus of functions taking values in normed spaces. The exposition is essentially elementary, though on are occasions appeal is made to deeper results. The theory of vector-valued functions of one real variable is particularly straightforward, and this forms the substance of the initial chapter. A large part of the book is devoted to applications. An extensive study is made of ordinary differential equations. Extremum problems for functions of a vector variable lead to the calculus of variations and general optimisation problems. Other applications include the geometry of tangents and the Newton-Kantorovich method in normed spaces. The three historical notes show how the masters of the past (Cauchy, Peano…) created the subject by exa

Forensic facial reconstruction is the reproduction of an individual's face from skeletal remains. Used when other forms of identification are very difficult or impossible, it can give a name to the dead in forensic cases, or in archaeological contexts, provide a tangible impression of real individuals from our past. This comprehensive work starts with a discussion of the importance of the face in society and the history of facial reconstruction, going on to evaluate the accuracy of modern reconstruction methods. The Manchester method of facial reconstruction, and the relationships between the hard and soft tissues of the face are described in detail. Uniquely, it also describes the methods and problems associated with reconstructing the faces of children. Collating all published facial tissue data and describing tissue variations with reference to age, sex, stature and ethnic origin, this book will be an important reference volume for all practitioners in the field.

The technique of aerial photography, widely recognized as of immense value to field archaeologists, had been little used in Ireland, although the relatively slight disturbance of land by modern ploughing or industrial development makes Ireland a particularly suitable region for the identification of ancient features by this method. The results of the surveys carried out by the Cambridge Committee for Aerial Photography between 1963 and 1968 are nevertheless surprising. Many ancient earthworks have been revealed by differences in soil-colour or crop-growth, and the natural and man-made environments of these and other prehistoric and early Christian settlements can be fully appreciated. The pattern of settlement emerges over a wide area, as does the character of large and complex sites such as Tara, while detailed oblique views pick out smaller structures invisible on the ground.

In this valuable collection of essays, published to coincide with the tercentenary of Handel's birth, Reinhard Strohm examines the relationship between Handel's great operas and the earlier European Baroque tradition, focusing on the Italian school, to which they are so crucially indebted. Handel's immediate heritage included the figures of Scarlatti, Gasparini and Vivaldi; this book establishes that context, concentrating on contemporary operatic practice, and proceeds to analyse three of Handel's best-known works. It shows how they elaborate and develop the style and method of the Italian operatic theatre, embracing previous traditions and synthesizing them with a new and exciting accentuation.

Avoiding overly large blocks of code used in most other database programming books, this book shows a simple and easy way to create database programs and explains how to build professional and practical databases more efficiently. In addition to Design Tools and Wizards, the runtime object method is also discussed and analyzed to let users design and implement more sophisticated data-driven applications with complicated coding techniques. Three popular database systems – Microsoft Access, SQL Server 2005, and Oracle Database 10g Express Edition (XE) – are discussed in detail, with practical examples and sample projects. This book will appeal to college students, programmers, and software engineers alike. Sample code and additional exercise questions for students, as well as solutions and lecture slides for instructors, are available via the Web (www.cambridge.org/9780521712354).

'Science, Technology, and Society' - STS - has become a major educational theme. There are many courses in schools, universities and other institutions, dealing with all sorts of topics such as the history of science, energy policy, industrial innovation, technology assessment, Third World development, scientific method, and so on. But what is this subject really about? Why should it be taught? Who should study it? What should they learn? How should the subject be approached? Who should teach it? These questions are being asked by both teachers and students in many fields of science, engineering, medicine, social studies, and the humanities. This informal account of the rationale of STS education shows how many diverse factors are involved - the philosophy and sociology of science and education, social and cultural objectives, political ideologies, vocational needs, scholarly standards, institutional capabilities, etc., not to mention the practical realities of teaching and learning at

Stalin's abrupt resolution of the crucial Soviet economic debate of the twenties - on the pace and method of industrialization - forced upon many the alternative of imprisonment or flight. Among them were not only political opponents and anti-collectivist peasants, but also economic officials and academics who argued an alternative path for socialist planning: had not the author of this book left the Soviet Union for Germany in 1920, he would have been a defendant in the trial of Mensheviks of March 1931. The life and work of economist friends and colleagues, condemned to long terms of imprisonment which few survived, form the principal part of this study, for which Naum Jasny drew on their writings before and after the Revolution and on a personal knowledge shared by scarcely anyone outside the USSR.

When Gottfried Wilhelm Leibniz first arrived in Paris in 1672 he was a well-educated, sophisticated young diplomat who had yet to show any real sign of his latent mathematical abilities. Over his next four crowded, formative years, which Professor Hofmann analyses in detail, he grew to be one of the outstanding mathematicians of the age and to found the modern differential calculus. In Paris, Leibniz rapidly absorbed the advanced exact science of the day. During a short visit to London in 1673 he made a fruitful contact with Henry Oldenburg, the secretary of the Royal Society, who provided him with a wide miscellany of information regarding current British scientific activities. Returning to Paris, Leibniz achieved his own first creative discoveries, developing a method of integral `transmutation' through which lie derived the 'arithmetical' quadrature of the circle by an infinite series. He also explored the theory of algebraic equations. Later, by codifying existing tangent and quadr

Human-Computer Interaction draws on the fields of computer science, psychology, cognitive science, and organisational and social sciences in order to understand how people use and experience interactive technology. Until now, researchers have been forced to return to the individual subjects to learn about research methods and how to adapt them to the particular challenges of HCI. This book provides a single resource through which a range of commonly used research methods in HCI are introduced. Chapters are authored by internationally leading HCI researchers who use examples from their own work to illustrate how the methods apply in an HCI context. Each chapter also contains key references to help researchers find out more about each method as it has been used in HCI. Topics covered include experimental design, use of eyetracking, qualitative research methods, cognitive modelling, how to develop new methodologies and writing up your research.
