David Harrison – författare

Medieval bridges are startling achievements of design and engineering comparable with the great cathedrals of the period, and are also proof of the great importance of road transport in the middle ages and of the size and sophistication of the medieval economy. David Harrison rewrites their history from early Anglo-Saxon England right up to the Industrial Revolution, providing new insights into many aspects of the subject. Looking at the role of bridges in the creation of a new road system, which was significantly different from its Roman predecessor and which largely survived until the twentieth century, he examines their design. Often built in the most difficult circumstances: broad flood plains, deep tidal waters, and steep upland valleys, they withstood all but the most catastrophic floods. He also investigates the immense efforts put into their construction and upkeep, ranging from the mobilization of large work forces by the old English state to the role of resident hermits and the charitable donations which produced bridge trusts with huge incomes. The evidence presented in The Bridges of Medieval England shows that the network of bridges, which had been in place since the thirteenth century, was capable of serving the needs of the economy on the eve of the Industrial Revolution. This has profound implications for our understanding of pre-industrial society, challenging accepted accounts of the development of medieval trade and communications, and bringing to the fore the continuities from the late Anglo-Saxon period to the eighteenth century. This book is essential reading for those interested in architecture, engineering, transport, and economics, and any historian sceptical about the achievements of medieval England.

Medieval bridges are startling achievements of design and engineering comparable with the great cathedrals of the period, and are also proof of the great importance of road transport in the middle ages and of the size and sophistication of the medieval economy. Dr Harrison has undertaken the first thorough study of bridges and in this book he rewrites their history from early Anglo-Saxon England right up to the Industrial Revolution, providing new insights into many aspects of the subject.

Workshop Machining is a comprehensive textbook that explains the fundamental principles of manually operating machinery to form shapes in a variety of materials. It bridges the gap between people who have traditional toolmaking skills and those who have been trained in programming and operation of CNC machines in a focused production environment, rather than general machine shop. Using a subject-based approach, David Harrison intuitively guides readers and supplies practical skills. The chapters cover everything from the basic machine controls to advanced cutting operations using a wide range of tooling and work-holding devices. Theory and practice are shown via a mixture of diagrams, text and illustrated worked examples, as well as through exercises.The book is ideal for students and lecturing staff who participate in, or lead, practical machining sessions, and for those who wish to further develop their machining skills. It also serves as an excellent reference to understand the principles and limitations of producing shapes with cutters that move in a limited combination of linear and radial paths.

Why are financial prices so much more crisis-prone and unstable than real economy prices? Because they are doing different things. Unlike real economy prices, rooted in the real goods and services produced and exchanged, financial prices attempt to value future income flows from financial and capital assets. These valuations fluctuate erratically because expectations of the future fluctuate – and large liquid financial markets can amplify, rather than correct, these effects. The book builds on the insights of economists Frank Knight and John Maynard Keynes, that uncertainty of the future is essential to understand the processes of economic production and capital investment, and adds to this Karl Popper's general explanation of how expectations of an uncertain future are formed and tested through a trial and error process. Rather than relying on fluctuating financial prices to provide a guide to an uncertain future, it suggests a better approach would be to adopt the methods common to other branches of science, and create testable (falsifiable) theories allowing reasonable predictions to be made. In finance, the elements of one such theory could be based on the concept of forecasting yield from capital assets, which is a measurable phenomenon tending towards aggregate and long-term stability, and where there is a plentiful supply of historic data. By methods like this, financial economics could become a branch of science like any other. To buttress this approach, the widely accepted public policy objective of promoting real economy price stability could be widened to include financial price stability.

Children, their World, their Education is the definitive text for students, teachers, researchers, educational leaders and all who are interested in primary education. As the culmination of the Cambridge Primary Review, the most comprehensive enquiry into English primary education for half a century, its publication provoked instant and dramatic headlines. Widespread support from teachers and eminent public figures demonstrated that the book had identified the issues that really mattered. Ministerial unease showed that here were findings that politicians could not ignore.But Children, their World, their Education is much more than a report. It is an unrivalled educational compendium that systematically covers the issues that are central to the daily work of students, teachers and heads. For trainee teachers on undergraduate and postgraduate courses it effectively maps the territory of primary education and provides the context, information and insight which are essential to the development of classroom skill. Its vast range of carefully evaluated evidence makes it a core resource for those undertaking research and advanced study. Its direct engagement with the policy process during a period of unprecedented change makes it an indispensable tool for policy analysis. It places England’s education system in the global context, and combines evidence on recent developments with a vision of how primary education should be.Part 1 sets the scene and tracks primary education policy since the 1960s.Part 2 examines children’s development and learning, their needs and aspirations, and their lives in a diverse society and fragile world.Part 3 explores what goes on in schools, from the vital early years to educational aims and values, the curriculum, pedagogy and classroom practice, assessment, standards and school organisation.Part 4 deals with the system as a whole: educational ages and stages, the work and training of primary teachers, school leadership, local authorities, funding, governance and policy.Part 5 pulls everything together with 78 conclusions and 75 recommendations for policy and practice.Companion volume: The Cambridge Primary Review Research Surveys, edited by Robin Alexander with Christine Doddington, John Gray, Linda Hargreaves and Ruth Kershner.

Competition law underpins the market economy by prohibiting anti-competitive agreements and practices, and the abuse of dominant positions in the market. Until the financial crisis it was widely assumed that the financial services industry was highly competitive. This book explores the extent to which this is the case. By analysing crisis and pre-crisis competition law cases and examples from the UK, the EU and around the world, David Harrison asks whether there exists good reason for financial services to be treated differently from the rest of the market economy. The theory of market efficiency is not borne out in practice. He particularly draws upon John Maynard Keynes in examining the differences between price mechanisms in product markets for "normal" goods, and price mechanisms in financial and investment markets where expectations of the future tend to play a greater role, leading to greater price fluctuations. In this evaluation, the book examines aspects of the practical functioning of capital markets such as the phenomenon of herding behaviour by financial participants, how short-term behaviour by intermediaries can be to the disadvantage of savers and productive investment, the relationship between investment markets and product markets and the extent to which the same competition rules apply to undertakings involved in both. The book will be invaluable to students, researchers and practitioners of banking and finance law, and commercial and competition law..

The term CAD Framework has come to mean all of the underlying facilities provided to the CAD tool developer, the CAD system integrator and the end user (IC or system designer) which are necessary to facilitate their tasks. Broadly speaking, these three groups of people represent the users of the CAD Framework, each with their own needs and particular emphasis. This book presents a general discussion of the major components of a CAD Framework and their relationships to one another. Each area is then presented in more detail. A brief review of the state-of-the-art is presented. Since the approach taken to the development and enhancement of CAD frameworks has had more impact on their success or failure than any particular design decision, some observations on this topic are included in chapter nine: "Implementing a CAD Framework". Finally the influence of related disciplines and the ongoing software standards efforts on the area of CAD environments is reviewed.

Many less developed countries are expanding their tourism industries and these are seen to be crucial to their economic development. Yet such activities can also create social, cultural and environmental problems.This book provides a review of many of the key issues involved in tourism in developing countries and presents a range of case studies. These are interpreted from a perspective of the sociology and anthropology of development. Case study chapters are presented from Africa, Asia, the Caribbean, Latin America and Oceania. The book provides essential reading for advanced students and researchers in tourism and development studies.

Pacific Island Countries have been shown to be especially vulnerable to such external influences as natural disasters, political unrest and downturns in the global economy and their tourism industries have been notably affected. In particular, they typically have a narrow resource base and a fragile and often vulnerable natural environment. While there is some research on islands and small states, there is a dearth of information on the South Pacific and very little research is being undertaken in the region compared to other geographical regions in the world. This volume brings together current work in Pacific Island tourism.In this collection, three main themes arise: Images of the South Pacific; Socio-economic Impacts of Tourism; and Pacific Island Countries and the Outside World. The first focus is on the question of image, namely, stereotypes of a destination held by tourists and potential tourists, the extent to which residents, for their part, really welcome visitors, and the role tourism might play in changing pre-established images. The second theme is tourism's impacts, notably the economic and socio-cultural effects of international tourism's intrusion in the region which, though often hotly debated, have attracted relatively little empirical research. The third focus is on the challenges of how PICs articulate with their external geo-political and physical environment. These involve existing relations with formal colonial centres, geographical isolation, the need for greater air access to the outside world and for more tourists, and the continuing threat to several PICs of global warming, which increased air travel will inevitably exacerbate. This text will be of interest to tourism students, researchers and academics in the fields of tourism, development studies and cultural studies.
