Hvatum, product development manager, Schlumberger “If you have need of changing your organization, and especially of introducing new techniques, then you want to understand what is in this book. It will help you avoid common pitfalls that doom many such projects and will show you a clear path to success. The techniques are derived from the experience of many individuals and organizations. Many are also fun to apply. This stuff is really cool—and really hot.” —Joseph Bergin, professor of computer science, Pace University, New York “If change is the only guarantee in life, why is it so hard to do? As this book points out, people are not so much resistant to change itself as they are to being changed. Mary Lynn and Linda have successfully used the pattern form to capture and present the recurring lessons of successful change efforts and have placed a powerful knowledge resource in the hands of their readers.” —Alan O'Callaghan, researcher, Software Technology Research Laboratory, De Montfort University, United Kingdom “The most difficult part of absorbing patterns, or any technology, into an organization is overcoming the people issues. The patterns in this book are the documentation of having gone through that experience, giving those that dare push the envelope a head start at success.”—David E. DeLano, IBM Pervasive Computing “If you have ever wondered how you could possibly foster any cultural changes in your organization, in this book you will find a lot of concrete advice for doing so. I recommend that everyone read this book who has a vast interest in keeping his or her organization flexible and open for cultural change.” —Jutta Eckstein, Independent Consultant, Objects In Action Author of Agile Software Development in the Large 48 Patterns for Driving and Sustaining Change in Your Organization Change.

"One of the great things about the book is the way the authors explain concepts very simply using analogies rather than programming examples–this has been very inspiring for a product I'm working on: an audio-only introduction to OOP and software development." –Bruce Eckel "...I would expect that readers with a basic understanding of object-oriented programming and design would find this book useful, before approaching design patterns completely. Design Patterns Explained complements the existing design patterns texts and may perform a very useful role, fitting between introductory texts such as UML Distilled and the more advanced patterns books." –James Noble Leverage the quality and productivity benefits of patterns–without the complexity! Design Patterns Explained, Second Edition is the field's simplest, clearest, most practical introduction to patterns. Using dozens of updated Java examples, it shows programmers and architects exactly how to use patterns to design, develop, and deliver software far more effectively. You'll start with a complete overview of the fundamental principles of patterns, and the role of object-oriented analysis and design in contemporary software development. Then, using easy-to-understand sample code, Alan Shalloway and James Trott illuminate dozens of today's most useful patterns: their underlying concepts, advantages, tradeoffs, implementation techniques, and pitfalls to avoid. Many patterns are accompanied by UML diagrams. Building on their best-selling First Edition, Shalloway and Trott have thoroughly updated this book to reflect new software design trends, patterns, and implementation techniques. Reflecting extensive reader feedback, they have deepened and clarified coverage throughout, and reorganized content for even greater ease of understanding. New and revamped coverage in this edition includes Better ways to start "thinking in patterns" How design patterns can facilitate agile development using eXtreme Programming and other methods How to use commonality and variability analysis to design application architectures The key role of testing into a patterns-driven development process How to use factories to instantiate and manage objects more effectively The Object-Pool Pattern–a new pattern not identified by the "Gang of Four" New study/practice questions at the end of every chapter Gentle yet thorough, this book assumes no patterns experience whatsoever. It's the ideal "first book" on patterns, and a perfect complement to Gamma's classic Design Patterns. If you're a programmer or architect who wants the clearest possible understanding of design patterns–or if you've struggled to make them work for you–read this book.

In this book, Nina Sylvanus tells a captivating story of global trade and cross-cultural aesthetics in West Africa, showing how a group of Togolese women—through the making and circulation of wax cloth—became influential agents of taste and history. Traveling deep into the shifting terrain of textile manufacture, design, and trade, she follows wax cloth around the world and through time to unveil its critical role in colonial and postcolonial patterns of exchange and value production. Sylvanus brings wax cloth’s unique and complex history to light: born as a nineteenth-century Dutch colonial effort to copy Javanese batik cloth for Southeast Asian markets, it was reborn as a status marker that has dominated the visual economy of West African markets. Although most wax cloth is produced in China today, it continues to be central to the expression of West African women’s identity and power. As Sylvanus shows, wax cloth expresses more than this global motion of goods, capital, aesthetics, and labor—it is a form of archive where intimate and national memories are stored, always ready to be reanimated by human touch. By uncovering this crucial aspect of West African material culture, she enriches our understanding of global trade, the mutual negotiations that drive it, and the how these create different forms of agency and subjectivity.
