This is an updated edition of an original and controversial book. As well as revising parts of the text and substantially updating the bibliography, in a new Appendix the author takes a more polemical stance and enters into a discussion of the nature and range of different interpretations. The book is divided into three parts; Interpretation, Evidence, and Later developments. The first part presents several new interpretations of the idea of ratio in early Greek mathematics and illustrates them in detailed discussions of several texts. Part Two focuses on the sources themselves, and questions the depth of modern knowledge of Plato's Academy during his lifetime, the source of our text of Euclid's Elements, and modern understanding of early Greek mathematics. The final part contrasts some of the evidence from early and late antiquity and then gives a historical account, since the seventeeth century, of the theory of continued fractions, our version today of the mathematics underlying the reconstruction. From reviews of the first edition: '...a real treat.' Greece and Rome '...cites an impressive array of evidence...The result should be widely read by classicists and mathematicians as well as historians of mathematics.' ISIS '...he enters into classical scholarship here with a really 'new reconstruction' of early Greek mathematics.' Nature '...this fascinating book...will arouse the interest and command the admiration of any historically minded lover of mathematics with a taste for the unorthodox.' Institute of Mathematics and its Applications 'This book, speculative in the best sense, engages the ancient material on its own terms in setting forth what the Greeks might have thought and done...While the book represents an important departure in historical research in its reaching beyond the spare formalism of surviving materials to an understanding of motivation and perception, its careful documentations and technical descriptions make it valuable in a more traditional way.'

This book traces the history of youth culture from its origins among the student communities of inter-war Britain to the more familiar world of youth communities and pop culture. Grounded in extensive original research, it explores the individuals, institutions and ideas that have shaped youth culture over much of the twentieth century.

The main principle behind cognitive behaviour therapy is that a client's emotional and behavioural disturbances are not determined by events, but by the way he or she views them. This book describes the clinical guidelines and detailed therapy procedures used in the practice of cognitive behaviour therapy for patients with schizophrenic disorders.

The early recognition and treatment of psychosis--particularly in adolescents and young adults--is increasingly accepted as an important factor in the individual experience of mental illness, which can have major implications for mental health care and treatment. This book is one of the first books available on the treatment of psychosis.

First Published in 1996. The first generation of British teenagers- young people eager to spend a significant proportion of their wages on consumer goods and services such as cosmetics, clothes, magazines, records, motorcycles, cinemas and dance halls- is generally regarded as that of the 1950s and 1960s. The same group, sociologists and economic and social historians have claimed, was the first to enjoy the autonomy in the labour market and to experience low unemployment. This study argues convincingly that in fact a teenage culture in modern sense already existed in the period between the two world wars. The book is grounded in extensive original research; on hitherto unexploited sources such as the records of the interwar Juvenile Employment Bureaux; on the records of youth movements ranging from the Boy Scouts to inner-city lads' and girls' clubs; on magazines aimed at youth, from millgirl magazines to specialist film, music and hobbies publications; and on contemporary social surveys, newspapers and oral history.

What are the potentials - and limitations - of usage statistics in libraries?As libraries increase their use of electronic resources, the value of quality evaluation of usage statistics has gained greater importance. Usage Statistics of E-Serials tackles this difficult issue by exploring in detail the proper evaluation of the level of usage of electronic resources. Noted experts discuss their own experiences in the field from multiple viewpoints and backgrounds, providing the reader with a well-rounded view of the entire topic. Issues comprehensively examined include the gathering and processing of statistics, costs and benefits of e-journals, evaluation and interpretation of data, and the comparison of different types of data collection methods.Usage Statistics of E-Serials reviews a range of situations and experiences of librarians and administrators in several different academic libraries. These authorities offer approaches and strategies to help readers more fully understand how to best manage those crucial resources.
