Social Research
`This is an impressively detailed, clearly written book.... It is a book that I would like students to read′ - Clive Seale, Goldsmiths College, London Social Research: Theory, Methods and Techniques presents an understanding of social research practice through appreciation of its foundations and methods. Stretching from the philosophy of science to detailed descriptions of both qualitative and quantitative techniques, it illustrates not only `how′ to do social research, but also `why′ particular techniques are used today. The book is divided into three parts: Part One: Illustrates the two basic paradigms - quantitative and qualitative - of social research, describing their origins in philosophical thought and outlining their current interpretations. Part Two: Devoted to quantitative research, and discusses the relationship between theory and research practice. It also presents a discussion of key quantitative research techniques. Part Three: Examines qualitative research. Topics range from classical qualitative techniques such as participant observation, to more recent developments such as ethnomethodological studies. Overall, the author offers an engaging contribution to the field of social research and this book is a reminder of the solid foundations upon which most social research is conducted today. As a consequence it will be required reading for students throughout the social sciences, and at various levels.
Approximation Theory and Methods

Most functions that occur in mathematics cannot be used directly in computer calculations. Instead they are approximated by manageable functions such as polynomials and piecewise polynomials. The general theory of the subject and its application to polynomial approximation are classical, but piecewise polynomials have become far more useful during the last twenty years. Thus many important theoretical properties have been found recently and many new techniques for the automatic calculation of approximations to prescribed accuracy have been developed. This book gives a thorough and coherent introduction to the theory that is the basis of current approximation methods. Professor Powell describes and analyses the main techniques of calculation supplying sufficient motivation throughout the book to make it accessible to scientists and engineers who require approximation methods for practical needs. Because the book is based on a course of lectures to third-year undergraduates in mathematics at Cambridge University, sufficient attention is given to theory to make it highly suitable as a mathematical textbook at undergraduate or postgraduate level.
