Language serves as both a symbol and a definer of culture. The well-being and integrity of a culture depend heavily on the strength and vitality of its associated language. It is for this reason that the process of language change within particular cultures needs to be monitored and scrutinized. This volume is a map-based analysis of patterns of language change, specifically the Welsh language. It concludes that the prime influences on the language derive from the large-scale socio-economic changes which have taken place in western society as a whole since the end of World War II.

This is an updated and extended version of the book previously published under the title "A Geography of the Welsh Language 1961-1991". The publication expands on the main themes addressed within the original text, makes reference to research, and presents sets of language data both for individuals and for households in wales. An additional chapter examines the impact of migration on the language, the relationship between social class and ability to speak Welsh, and the bases for the reproduction and maintenance of the language within the context of the family. The final chapter is extended and considers the prospects for the language, in the light of political and insitutional developments (including the Assembly), planning issues (most notably housing) and developments in the field of education. The implications of these and other socio-economic forces for the long-term well-being of the language are evaluated.

Statistical Concepts and Applications in Clinical Medicine presents a unique, problem-oriented approach to using statistical methods in clinical medical practice through each stage of the clinical process, including observation, diagnosis, and treatment. The authors present each consultative problem in its original form, then describe the process of problem formulation, develop the appropriate statistical models, and interpret the statistical analysis in the context of the real problem. Their treatment provides clear, accessible explanations of statistical methods. The text includes end-of-chapter exercises that help develop formulatory, analytic, and interpretative skills.
