This introductory course on the classical Boundary Element Method also contains advanced topics such as the Dual Reciprocity and the Hybrid Boundary Element Methods. The latter methods are extensions that permit the application of BME to anisotropic materials, as well as multi-field problems and fluid-structure interaction. The class-tested textbook offers a clear and easy-to-understand introduction to the subject, including worked-out examples that describe all the basic features of the method. The first two chapters not only establish the mathematical basis for BEM but also review the basics of continuum mechanics for field problems, perhaps a unique feature for a text on numerical methods. This helps the reader to understand the physical principles of the field problems, to apply the method judiciously, and toe critically evaluate the results.

Over the past decades, the Boundary Element Method has emerged as a ver satile and powerful tool for the solution of engineering problems, presenting in many cases an alternative to the more widely used Finite Element Method. As with any numerical method, the engineer or scientist who applies it to a practical problem needs to be acquainted with, and understand, its basic principles to be able to apply it correctly and be aware of its limitations. It is with this intention that we have endeavoured to write this book: to give the student or practitioner an easy-to-understand introductory course to the method so as to enable him or her to apply it judiciously. As the title suggests, this book not only serves as an introductory course, but also cov ers some advanced topics that we consider important for the researcher who needs to be up-to-date with new developments. This book is the result of our teaching experiences with the Boundary Element Method, along with research and consulting activities carried out in the field. Its roots lie in a graduate course on the Boundary Element Method given by the authors at the university of Stuttgart. The experiences gained from teaching and the remarks and questions of the students have contributed to shaping the 'Introductory course' (Chapters 1-8) to the needs of the stu dents without assuming a background in numerical methods in general or the Boundary Element Method in particular."

Consistency and Credibility? identifies in its first part the extent of correlation between actual environmental performance, the use of physical environmental performance indicators and corporate environmental reporting in the paper and electricity industries in Germany and the UK. The results suggest environmental performance is mainly country-related, possibly due to differences in environmental legislation. This implies that any assessment of the relationship between environmental and economic performance of firms needs to be based on actual environmental performance data and cannot take reporting quality or information about the intensity of use of specific tools, such as environmental performance indicators as a proxy variable. The second part of the book therefore analyses the relationship between environmental and economic performance. Based on the results, the book's second part concludes that for firms in environmentally-intensive industries it is difficult to create a positive link between their environmental and economic performance, and that market settings as well as strategy considerations both can have an effect, but situational aspects determine which of these dominates. Consistency and Credibility? provides useful information for practitioners as well as deeper insights for academics about the link of environmental reporting and environmental performance measurement and how this interacts with economic success. It thus reveals valuable strategic insights in how aiming for corporate sustainability can help to create business success and which factors are critical for achieving this.
