Learn How to Solve Problems from the Process of Solving Problems

The Provident Sea describes the history of fish stock management (including whales and seals). The need for management arose from the industrialization of capture. Hence the preindustrial fisheries are covered, in particular the old cod fishery on the Grand Bank and the herring fishery in the North Sea. The origins of fishery science and of whaling science are described, as it the development of science and institution until 1965 in fisheries, whaling and sealing. In the 1960s and 1970s the second industrialization took place over the world ocean mainly through the activities of the Russians and Japanese. The consequence of this was the 'law of the Sea' Conference and the eventual management by the coastal state. This book traces, on the basis of the original scientific material, the history of the management of 'the provident sea' up to when problems of overexploitation have had dramatic effects upon stocks.

This graduate/research level text is a self-contained exposition of the applications of kinetic theory to basic problems in modern cosmology, such as the role of stable and unstable massive neutrinos and the theory of cosmological helium production. There has been rapid development of the theory of the origin and evolution of the universe in recent years, stimulated in large part by new observations and theories in astrophysics and particle physics. This book takes a different approach and studies what can be concluded from the application to cosmological problems of kinetic theory and, in particular, the Boltzmann equation and its solutions. The book begins with a brief survey of the necessary relativity, cosmodynamics, and kinetic theory, before going on to discuss specific problems, such as the role of stable and unstable massive neutrinos, electron-poritron annihilation, and the theory of cosmological helium production. The focus is in obtaining both theoretical understanding and c

A practicing homeopathic physician discusses the homeopathic remedies and first-aid procedures appropriate for treating common athletic problems, from heat-stress to sprains. He shows how homeopathic

This timely volume presents a synthesis of the ideas that emerged from a multidisciplinary colloquium held at the National Center for Atmospheric Research in August 1985. The aim was to assess the impact of drought as a major factor in the agrarian crisis in sub-Saharan Africa. Leading authorities engage in discussion of the African environment, the socio-political factors that generate famine, case studies of the effects of famine on these social structures, and finally possible lessons to be learnt on dealing with famine worldwide, thus developing an up-to-date and cohesive study of the problems of African development. Despite the current popular interest in the African famine problem, Drought and Hunger in Africa is the first major collection of the results that have emerged from the recent profusion of research relating to the subject. As such, this book has relevance, not only in Africa, but also to scientists, social-scientists and policy makers in the West, and to other areas of

This book represents a comprehensive overview of the present state of progress in three related areas of combinatorics. It comprises selected papers from a conference held at the University of Montreal. Topics covered in the articles include association schemes, extremal problems, combinatorial geometrics and matroids, and designs. All the papers contain new results and many are extensive surveys of particular areas of research. Particularly valuable will be Ivanov's paper on recent Soviet research in these areas. Consequently this volume will be of great attraction to all researchers in combinatorics and to research students requiring a rapid introduction to some of the open problems in the subject.

This book contains a modern treatment of production economics from a dual perspective, with special emphasis on recent developments. Results that were scattered throughout professional journals and monographs are now gathered into an integrated approach using a common notation. The book prepares the reader to apply the tools of the dual approach to real world problems and data sets. Particular care has been devoted to choosing topics for discussion that achieve this goal. Throughout the book there are worked examples and exercises, which are geared toward developing the reader's facility in using modern developments in production economics. Separate chapters are devoted to production, cost, and profit functions. Other topics include flexible functional forms, aggregation across inputs and outputs using the theory of separable structures, aggregation over economic optimizing firms, the representation of multioutput technologies, and the analysis and measurement of technical change from

This textbook, addressed primarily to physics and engineering students, is a comprehensive introduction to waves and oscillations, both mechanical and electromagnetic. Elementary aspects of matter waves are also considered. One objective is to illustrate the physics involved in the description and analysis of waves through a wide range of examples, from purely mechanical and purely electromagnetic to coupled electro-mechanical waves, such as plasma oscillations and hydromagnetic waves. In this process, the use of complex amplitudes in the mathematical analysis is illuminated and encouraged to make tractable a wider range of problems than is ordinarily considered in an introductory text. General concepts and wave phenomena such as wave energy and momentum, interference, diffraction, scattering, dispersion, and the Doppler effect are illustrated by numerous examples and demonstrations. Among the special topics covered are waves on periodic structures and in solids, wave guides, a detaile

How do I decide I am ill; how do I decide that my children are ill? How do I learn effective ways of conveying to others that I am ill? This book discusses the languages of illness which we use to present our discomforts to others through an exploration of the child's world of illness. It looks at how illness concepts are introduced to children, how the causes of illness and 'germ' rationales are incorporated into the socialisation of children, and how a particular morality about health and illness is expressed. Besides the analysis of the social context within which the children's views are developing, the book presents the children's own views from three years old up to thirteen. How we talk about illness can have as important consequences as the methods we use to cure it. This book persuades the reader to look more closely at the language of illness, allowing a reappraisal to medical practice, school health programmes and class teaching, health education and even the differences in

In Remembering Reconsidered, the new ecologically oriented study of memory makes contact with more traditional approaches. The emerging result may be what several of the authors have begun to call 'functionalism': a concern with the adaptive significance of memory in ordinary life coupled with a careful analysis of the variables on which it depends. In different ways, the chapters reflect this concern. The editors bring together a diverse collection of studies on remembering, using subjects ranging from folk songs to 'crib talk'. Introductory chapters weave these themes together, developing an underlying sense of the project of the volume as a whole. This is the second volume in the Emory Symposia on Cognition. The Emory Cognition Project, directed by Ulric Neisser, emphasizes an ecological approach to problems in theoretical, experimental, and applied cognitive psychology.

The concept of 'scripture' as written religious text is re-examined in this close analysis of the traditions of oral use of the sacred writings of religions around the world. Pointing out the central importance of the oral and aural experience of religious texts in the life of religious communities of both Eastern and Western cultures, William Graham asserts the need for a new perspective on how scripture has been appropriated and used by the vast majority of all people who have been religious, most of whom could neither read nor write. Graham first probes the history of literacy, focusing on the prominent role of the written word in modern Western culture and its history in Western civilisation. He then considers the unique case of scripture, examining the problems of communication of texts to illiterate or semi-literate religious communities, the various oral uses of scripture, and affective impact of the spoken holy word vis-á-vis the silently written page.

This book is designed to help software engineers and project managers understand and solve problems involved in developing complex software systems. It provides guidelines and tools for managing the t

This informative book, first published in 1987, presents the theories of community ecology within the context of a natural example. The text describes and examines issues in community ecology and shows how research on salamanders has helped to solve some of the problems surrounding the theories. Salamanders exist in stable populations of the kind assumed in community theory and are more appropriate than most other animals for research on the applications of that theory. The interesting and meaningful results, collected from observation on these excellent subjects posed challenges to beliefs within community ecology. Life histories of salamanders, fieldwork in distinctly differing habitats, competition, predation and evolution are discussed in an easily readable text. Professional ecologists and students of community ecology and herpetology will be interedted in the information synthesised in this book.

Menander (c. 341-291 BC) was the foremost innovator of Greek New Comedy, a dramatic style that moved away from the fantastical to focus upon the problems of ordinary Athenians. This collection contain

First published in 1988, this book is a manual of methods for solving problems in radiative transfer. Several of the methods, on operator perturbation as well as on polarised radiative transfer, appeared for the first time in this volume, and the sections dealing with these topics each include introductory articles. The methods described are principally directed at astrophysical plasmas, but the methods are easily adaptable to applications involving other media where self-absorption of the radiation is important. The book is primarily intended for graduate students and research workers in the field of radiative transfer.

In this book, Jon Conrad and Colin Clark develop the theory of resource economics. To begin, they provide an introduction to the required techniques of dynamic optimization. Throughout the book they build the reader's understanding with many fully-worked problems and numerical examples. The authors have written this text in the belief that the theory and concepts of resource are more quickly learned, more effectively made operational, and more truly understood if the reader is exposed to carefully explained numerical examples. By working through the problems at the end of each chapter, students will learn the techniques to be used in empirical studies of natural resource systems. The first chapter provides an introduction to optimization, including constrained optimization, dynamic allocation problems, dynamic programming, continuous time problems, and the maximum principle, and a discussion of various numerical and graphical techniques. The remaining chapters deal in depth with the ec

In many problems of applied mathematics, science, engineering or economics, an energy expenditure or its analogue can be approximated by upper and lower bounds. This book provides a unified account of the theory required to establish such bounds, by expressing the governing conditions of the problem, and the bounds, in terms of a saddle functional and its gradients. There are several features, including a chapter on the Legendre dual transformation and some of its singularities. Many substantial examples and exercises are included, especially from the mechanics of fluids, elastic and plastic solids and from optimisation theory. The saddle functional viewpoint gives the book a wide scope. The treatment is straightforward, the only prerequisite being a basic knowledge of the calculus of variations. Part of the book is based on final-year undergraduate courses. This is developed into an account which will interest a wide range of students and professionals in applied mathematics, engineer

Research on women's roles in rural development has found that women's contribution to the rural economy is commonly underestimated and that women may find it difficult to benefit from the development process. Within this context, this book looks at the Soviet experience of development as reflected in the lives of rural women. It attempts to analyse the gains made and the problems still faced by rural women in a country where development policies have been accompanied by a formal commitment to sexual equality. In its introduction, the book briefly outlines the impact on rural women of social, economic and political change in the countryside from the revolution to 1960. It then goes on to examine in depth changes in the role and status of women in the Soviet countryside.

Many people learn the rudiments of the nitrogen cycle while at school, but the details of the various processes in the cycle are still not widely understood. Some of them are of great current interest, such as the use of nitrogen fixing crops to feed an increasing world population and the problems of pollution of groundwaters by nitrates. Denitrification (forming nitrogen gas) as a way of getting rid of waste from human and intensively farmed animals. This book describes the general processes of the nitrogen cycle, then gives examples of how the cycle is modified under particular ecological and geographical conditions. These examples are drawn from all the major areas of the world, and the impact of man via agriculture, forestry and fuel combustion is discussed. Numerous references are included. The book provides a background for all those whose specialist interests interact with nitrogen cycling, whether they are involved in research or have responsibility for managing the environment

The Democratic Dilemma seeks to explain Vermonters' extraordinary faith and idealism. It argues that Vermonters, as the most radical democrats of the Age of Revolution and conservators of New England's traditions, faced a dilemma: how to reconcile their commitment to competition, toleration, and popular sovereignty with their desire to defend an orderly and pious way of life. By embedding democratic ideals in their institutions and their society. Denominations and political parties clashed, townspeople and church members proved ungovernable, and young people grew wayward and rebellious. An economic and demographic crisis in the 1830s and 1840s compounded these problems by denying many inhabitants what they wanted most independent shops and farms for themselves and their descendants. None of these problems could he solved without restraining spiritual, political, and economic freedom and compromising the principles of Vermont's revolution.

Analyzing Love is concerned with four basic and neglected problems concerning love. The first is identifying its relevant features: distinguishing it from liking and benevolence and from sexual desire; describing the objects that can be loved and the judgements and aims required by love. The second question is how we recognize the presence of love and what grounds we may have for thinking it present in any particular case. The third is that of relating it to other emotions such as anger and fear, and, more generally, deciding where love stands in the contrast between emotions and attitudes. Finally, the book examines how we justify our loves: can we have, and do we need, reasons for loving? What types of judgement are appropriate to love? Can we criticize a lover for his or her choices?

In this cogent and accessible introduction to philosophy, the distinguished author of Mortal Questions and The View From Nowhere sets forth the central problems of philosophical inquiry for the beginn

Environmental external effects are evidence of the inability of market prices to reflect the interdependence of economic activities undertaken within a common environment. They are an essential - not a peripheral - feature of all market economics. This essay shows how external effects are produced by the interaction of the economy with its environment, using a classical mass-balance model. No matter how efficient the market may seem to be, the use of market prices to determine depletion and pollution decisions creates more problems than it solves. Far from sharing the stable or relatively stable equilibrium properties of most economic models, the market economy is shown to be forced by its environment through a seemingly chaotic sequence of states. Reliance on the market to accommodate each change of direction merely exaggerates the general instability of the system. The 'market solution' to environmental problems is shown to generate only increasing uncertainty, a progressive myopia,

John Maynard Smith was originally trained as an engineer but, despite important excursions into animal mechanics, ecology and ethology, he is now best known as an international authority on evolution. His pre-eminence is based in large part on original research contributions coupled with an uncanny ability for revealing simple explanations to apparently intractable problems. This wide-ranging volume contains a collection of new and original essays, all inspired by Maynard Smith's writings. The essays span the whole field of evolutionary biology: from microevolution to macroevolution; from evolutionarily stable strategies to sympatric speciation; and from population processes in plants to the arithmetic of assessment in animals.

This textbook is an introduction to the concept of factorization and its application to problems in algebra and number theory. With the minimum of prerequisites, the reader is introduced to the notion of rings, fields, prime elements and unique factorization. The author shows how concepts can be applied to a variety of examples such as factorizing polynomials, finding determinants of matrices and Fermat's 'two-squares theorem'. Based on an undergraduate course given at the University of Sheffield, Dr Sharpe has included numerous examples which demonstrate how frequently these ideas are useful in concrete, rather than abstract, settings. The book also contains many exercises of varying degrees of difficulty together with hints and solutions. Second and third year undergraduates will find this a readable and enjoyable account of a subject lying at the heart of much of mathematics.

Reviewing the course of English population history from 1066 to the eighties, this book challenges orthodoxies about the evolution of English family forms, and offers a bold interpretation of the inter-connections between social, economic, demographic and family history. Taking as the point of departure the well-known observations that England was the first industrial society, that it was the first society to have its peasantry replaced by proletarians and that it was a society that was always dominated by nuclear family households, the main question David Levine asks is how these elements were connected in time and space. In answering this, he looks to contemporaneous changes in the labour process, and, in particular, to the disposition of labour within the family. His central theme is the impact of proletarianisation on family formation. He argues that the explosive transformations of family and demography that occurred between 1780 and 1815 were the culmination of a protracted trans

This book reviews the phylogenetic data derived from molecular methods and from classical morphology, and analyses the contribution each can make to the study of evolution. Molecular biology and traditional areas of evolutionary biology such as morphology have not enjoyed a particularly happy marriage. Molecular biologists have the advantages of modernity, high technology, and visibility: their results often seem to represent the cutting edge of science, superseding and outmoding what went before. Nevertheless, this book shows that the partnership between those who study morphology and those who study molecules is alive and well: reconciliation is possible, necessary and inevitable because the problems involved in reconstructing the history of life do not change, whatever the source of the data. In eight chapters, leading exponents of molecular and morphological methods explore phylogeny, starting with hominoids, the most thoroughly studied group, then working outwards through the vert

This book provides a new translation of substantial extracts from the Qumran writings, which comprise an important part of the Dead Sea scrolls. The writings reflect the beliefs and practices of a religious community which existed on the shores of the Dead Sea between the middle of the second century BC and AD 68. They shed considerable light on the Essenes, whose movement had an important focus at Qumran. In addition to selecting the most significant legislative, poetic and liturgical writings, Professor Knibb provides a commentary dealing with major interpretative problems raised by the extracts.

This book gathers together essays, published and unpublished, in which Brian Hebblethwaite explores and defends the Christian doctrine of the Incarnation against its modern critics. He shows what would be lost from the Christian religion if non-incarnational Christology (a way of understanding Jesus Christ without belief in his divinity) were to be adopted by the Christian churches. He begins by examining some of the problems raised by this challenge to traditional doctrine, then considers the contribution of Austin Farrer to Christology, and goes on to analyse the recent trend towards Unitarianism in contemporary theology. In a new, concluding essay, Canon Hebblethwaite answers criticisms of his contribution to the current debate on the Incarnation.

It is the aim of this book to take undergraduates in science and engineering to an acceptable level of competence in network analysis. The author assumes no previous knowledge of the subject. The book starts from basic physical ideas and progresses through essential network laws and theorems to Fourier and Laplace transform methods of analysing transient and steady-state problems. Traditional transient and alternating-current theory is covered prior to introducing transform methods, since the author believes that the gain in physical insight from such an approach is invaluable. Throughout, the relevance of the analysis to practical electric and electronic circuits is stressed. This book will be of value to students in universities and polytechnics in physics and electrical and electronics engineering departments.

This book is a rigorous introduction to the abstract theory of partial differential equations. The main prerequisite is familiarity with basic functional analysis: more advanced topics such as Fredholm operators, the Schauder fixed point theorem and Bochner integrals are introduced when needed, and the book begins by introducing the necessary material from the theory of distributions and Sobolev spaces. Using such techniques, the author presents different methods available for solving elliptic, parabolic and hyperbolic equations. He also considers the difference process for the practical solution of a partial differential equation, emphasising that it is possible to solve them numerically by simple methods. Many examples and exercises are provided throughout, and care is taken to explain difficult points. Advanced undergraduates and graduate students will appreciate this self-contained and practical introduction.

Philosophical aesthetics is an area in which many strands of contemporary philosophical thinking meet. The contributors to this volume are aware of the wider logical, epistemological, moral and metaphysical implications raised by conceptual problems specific to aesthetics. Three themes recur and are taken up from different angles in several of the papers: pleasure – its nature and role in the experience of art and beauty; preference – figuring prominently in aesthetic appraising, appreciating and judging; and value – aesthetic value in particular, and the status of value in general. As these themes interweave, the complexities of aesthetics bring into focus some of the central issues in the philosophy of mind. The authors argue their cases with professional expertise and perceptive understanding of the arts, making significant and original contributions. This book should be of interest not only to philosophers but also to the readers who know, care and theorise about the arts. All the

Planning is an important human ability that guides behaviour and thereby complements instinctual fixed action patterns. How do people learn to plan? How do they develop the various skills that are implied by planfulness? This volume explores these questions as well as the concept of planning and its relationships to the concepts of problem-solving and organizational skills. The editors of this volume have drawn upon an international cadre of scholars to discuss the issues of planning and planful behaviours from a broad range of perspectives. The volume offers a comprehensive review and critical analysis of research and theory on the development of planning ability. Cognitive and developmental psychologists, educational researchers, and students hitherto frustrated by the complexity of the thinking about planning and fragmentation of the literature will find Blueprints for Thinking an invaluable resource.

The main aim of this book is to introduce the reader to the concept of comparison algebra, defined as a type of C*-algebra of singular integral operators. The first part of the book develops the necessary elements of the spectral theory of differential operators as well as the basic properties of elliptic second order differential operators. The author then introduces comparison algebras and describes their theory in L2-spaces and L2-Soboler spaces, and in particular their importance in solving functional analytic problems involving differential operators. The book is based on lectures given in Sweden and the USA.

Historians have so far made few attempts to assess directly the costs and benefits of Britain's investment in empire. This book presents answers to some of the key questions about the economics of imperialism: how large was the flow of finance to the empire? How great were the profits on empire investment? What were the social costs of maintaining the empire? Who received the profits, and who bore the costs? The authors show that colonial finance did not dominate British capital markets; returns from empire investment were not high in comparison to earnings in the domestic and foreign sectors; there is no evidence of continued exploitative profits; and empire profits were earned at a substantial cost to the taxpayer. They depict British imperialism as a mechanism to effect an income transfer from the tax-paying middle class to the elites in which the ownership of imperial enterprise was heavily concentrated, with some slight net transfer to the colonies in the process.

This book provides a comprehensive and rigourous study of the development of the British economy from the early eighteenth century onwards. It surveys and synthesises the prevalent literature on the origins of the growth of the economy and its topical problems, and challenges the conventional view that sees an industrial revolution as the starting point of Britain's fresh economic growth. Statistical studies have to a large extent established the pattern of growth and of the leading economic indicators. The book makes full use of these studies and surveys the main macroeconomic aggregates: wealth and income; investment and the financial system; production and productivity; demographic and economic growth; foreign trade and payments; and regional growth. It looks at the interpretations of the data, the issues raised and examines the major debates.
