In the present edition I have included "Supplements and Problems" located at the end of each chapter. This was done with the aim of illustrating the possibilities of the methods contained in the book, as well as with the desire to make good on what I have attempted to do over the course of many years for my students-to awaken their creativity, providing topics for independent work. The source of my own initial research was the famous two-volume book Methods of Mathematical Physics by D. Hilbert and R. Courant, and a series of original articles and surveys on partial differential equations and their applications to problems in theoretical mechanics and physics. The works of K. o. Friedrichs, which were in keeping with my own perception of the subject, had an especially strong influence on me. I was guided by the desire to prove, as simply as possible, that, like systems of n linear algebraic equations in n unknowns, the solvability of basic boundary value (and initial-boundary value) problems for partial differential equations is a consequence of the uniqueness theorems in a "sufficiently large" function space. This desire was successfully realized thanks to the introduction of various classes of general solutions and to an elaboration of the methods of proof for the corresponding uniqueness theorems. This was accomplished on the basis of comparatively simple integral inequalities for arbitrary functions and of a priori estimates of the solutions of the problems without enlisting any special representations of those solutions.

This study is an exploration of the collective values and activities of lay society in Western Europe between the tenth century and the thirteenth. Arguing that medieval attitudes and behaviour have been too readily defined in terms of hierarchical structures of government, clerical thought, or a narrow notion of kinship, the author instead places new emphasis on the horizontal bonds of collective association which permeated society in medieval England, France and Burgundy, Germany, the Netherlands, and Italy. By refocusing attention on the social and political values that characterized lay collective activity, this book offers a stimulating new approach to the history of medieval Europe. The second edition of this important study incorporates a substantial new introduction, which amplifies the arguments of the original edition and takes account of recent research. ON THE FIRST EDITION `all students of the Middle Ages and of collective organization will be indebted to Reynolds for this rich and original book. It will be a starting-point for discussion and the reference point for information', Times Literary Supplement This book is intended for students of medieval history.

COMPENSATION by Milkovich and Newman is the market-leading text in this course area. It offers instructors current research material, in depth discussion of topics, integration of Internet coverage, a modern design, excellent pedagogy, and a truly engaging writing style. George Milkovich and Jerry Newman are viewed as leading authorities in the field of Human Resource Management/Compensation. They consult with leading businesses, have won teaching awards, and publish in the leading journals. Milkovich received a career contribution award from WorldatWork (formerly American Compensation Association) in 2000. COMPENSATION examines the strategic choices in managing total compensation. The total compensation model introduced in chapter one serves as an integrating framework throughout the book. The authors discuss compensation issues in the context of current theory, research, and real-business practices. Milkovich/Newman strive to differentiate between beliefs and facts, and opinions from scholarly research. Adopters tell us that students get job offers based on the knowledge they get from this book.
