Sommario/riassunto

This book is dedicated to Dr. Benjamin William Remondi for many reasons. The project of writing a Global Positioning System (GPS) book was con­ ceived in April 1988 at a GPS meeting in Darmstadt, Germany. Dr. Remondi discussed with me the need for an additional GPS textbook and suggested a possible joint effort. In 1989, I was willing to commit myself to such a project. Unfortunately, the timing was less than ideal for Dr. Remondi. Therefore, I decided to start the project with other coauthors. Dr. Remondi agreed and indicated his willingness to be a reviewer. I selected Dr. Herbert Lichtenegger, my colleague from the Technical University Graz, Austria, and Dr. James Collins from Rockville, Maryland, U.S.A. In my opinion, the knowledge of the three authors should cover the wide spectrum of GPS. Dr. Lichtenegger is a geodesist with broad experience in both theory and practice. He has specialized his research to geodetic astron­ omy including orbital theory and geodynamical phenomena. Since 1986, Dr. Lichtenegger's main interest is dedicated to GPS. Dr. Collins retired from the U.S. National Geodetic Survey in 1980, where he was the Deputy Director. For the past ten years, he has been deeply involved in using GPS technology with an emphasis on surveying. Dr. Collins was the founder and president of Geo/Hydro Inc. My own background is theoretically oriented. My first chief, Prof. Dr. Peter Meissl, was an excellent theoretician; and my former chief, Prof. Dr.mult. Helmut Moritz, fortunately, still is.

Sommario/riassunto

"Goedele A. M. De Clerck presents cross-cultural comparative research that examines and documents where deaf flourishing occurs and how it can be advanced. She spotlights collective and dynamic resources of knowledge and learning; the coexistence of lived differences; social, linguistic, cultural, and psychological capital; and human potential and creativity. Deaf Epistemologies, Identity, and Learning argues for an inclusive approach to the intrinsic human diversity in society, education, and scholarship, and shows how emotions of hope, frustration, and humiliation contribute to the construction of identity and community. De Clerck also considers global to local dynamics in deaf identity, deaf culture, deaf education, and deaf empowerment. She presents empirical research through case studies of the emancipation processes for deaf people in Flanders (a region of Belgium), the United States (specifically, at Gallaudet University in Washington, DC), and the West African nation of Cameroon. These three settings illuminate different phases of emancipation in different contexts, and the research findings are integrated into a broader literature review and subjected to theoretical reflection. De Clerck's anthropology of deaf flourishing



draws from her critical application of the empowerment paradigm in settings of daily life, research, leadership, and community work, as she explores identity and well-being through an interdisciplinary lens. This work is centered around practices of signed storytelling and posits learning as the primary access and pathway to culture, identity, values, and change. Change driven by the learning process is considered an awakening--and through this awakening, the deaf community can gain hope, empowerment, and full citizenship. In this way, deaf people are allowed to shape their histories, and the result is the elevation of all aspects of deaf lives around the world"--
