Book Description
Jody Blake demonstrates in this book that although the impact of African-American music and dance in France was constant from 1900 to 1930, it was not unchanging. This was due in part to the stylistic development and diversity of African-American music and dance, from the prewar cakewalk and ragtime to the postwar Charleston and jazz. Successive groups of modernists, beginning with the Matisse and Picasso circle in the 1900s and concluding with the Surrealists and Purists in the 1920s, constructed different versions of la musique and la danse negre. Manifested in creative and critical works, these responses to African-American music and dance reflected the modernists' varying artistic agendas and historical climates.

Book Description
This book, based on Transport and Urban Development COST Action TU1208, presents the most advanced applications of ground penetrating radar (GPR) in a civil engineering context, with documentation of instrumentation, methods and results. It explains clearly how GPR can be employed for the surveying of critical transport infrastructure, such as roads, pavements, bridges and tunnels and for the sensing and mapping of underground utilities and voids. Detailed attention is also devoted to use of GPR in the inspection of geological structures and of construction materials and structures, including reinforced concrete, steel reinforcing bars and pre/post-tensioned stressing ducts. Advanced methods for solution of electromagnetic scattering problems and new data processing techniques are also presented. Readers will come to appreciate that GPR is a safe, advanced, non destructive and noninvasive imaging technique that can be effectively used for the inspection of composite structures and the performance of diagnostics relevant to the entire life cycle of civil engineering works.

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 28 (thesis year 1 983) a total of 10,661 theses titles from 26 Canadian and 197 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 28 reports theses submitted in-1983, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book Description
This Child-Friendly Schools (CFS) Manual was developed during three-and-a-half years of continuous work, involving the United Nations Children's Fund education staff and specialists from partner agencies working on quality education. It benefits from fieldwork in 155 countries and territories, evaluations carried out by the Regional Offices and desk reviews conducted by headquarters in New York. The manual is a part of a total resource package that includes an e-learning package for capacity-building in the use of CFS models and a collection of field case studies to illustrate the state of the art in child-friendly schools in a variety of settings.

Book Description
Against What? Against Whom? is a monograph about the author, film maker and video artist Harun Farocki. Its the first book about Farocki that is neither a purely academic publication nor an exhibition catalogue. it brings together the most diverse of themes, tonalities and approaches: alongside a complete filmography and list of installations, there are 21 contributions that take a discursive (or use drawings to) look at Farocki's complex oeuvre. Additionally there are two key Farocki texts, previous reflections on his film and video work, and a new text he has written especially for this book, which begins quite biographically and underhandedly becomes a short history of the making of films and art in (West) Germany over the past 40 years. The themes discussed are as varied as the authors involved, with much focus on individual Farocki films, beginning with the early political, Marxist, educational films, via his cinema direct films and his essay films, that have become classics in the meantime, up To The films and installations, which For The most make use of found footage of the most varied types of image, such as amateur recordings, archive pictures, surveillance images, technical images and computer animations. English text.

Book Description
Since the 1960s, poetry in French has been understood in terms of two competing approaches: searching for 'presence' on the one hand, 'littéralité' - refiguring the everyday - on the other. Contemporary forms of both are found in this anthology, from the 'new lyricism' of Bonhomme and Maulpoix to the refracted politics of 'post-poetry' in Tarkos and Gleize. The dichotomy, however, quickly breaks down and many poets refuse to be categorised in this way: recent publications include the interdisciplinary and collaborative work of poets such as Alferi, Chaton, Game and Macher; the focus on formal constraint in Métail and Espitallier; Portugal's exploration of the impact of new technologies. Writing the Real features 18 key contemporary French-language poets alongside English translations by leading poets and translators.

Book Description
One distinct feature of human society since the dawn of civilization is the systematic use of inorganic building materials, such as natural stone, unburnt and burnt soil, adobe and brick, inorganic binders like lime and cement, and reinforced concrete. Our heritage has cultural, architectural and technological value and preserving such structures is a key issue today. Planners and conservation scientists need detailed site surveys and analyses to create a database that will serve to guide subsequent actions. One factor in this knowledge base is an understanding of how historic materials were prepared and the crucial properties that influence their long-term behaviour. Any assessment of the way such materials perform must crucially be based on an understanding of the methods used for their analysis. The editors here add to the knowledge base treating the materials used in historic structures, their properties, technology of use and conservation, and their performance in a changing environment. The book draws together 18 chapters dealing with the inorganic materials used in historic structures, such as adobe, brick, stone, mortars, concrete and plasters. The approach is complex, covering material characterisation as well as several case studies of historic structures from Europe, including Germany, Ireland, Italy, Poland, Portugal, Scotland, Slovenia and Spain, and the My Sõn Temples in Vietnam. An equally important component of the book covers the analysis of materials, together with a treatment of sustainable development, such as the protection of monuments from earthquakes and climate change. The authors are all leading international experts, drawn from a variety of backgrounds: architecture, civil engineering, conservation science, geology and material science, with close links to professional organisations such as ICOMOS or universities and research centres throughout Europe. Audience: This book will be of interest to geologists, engineers, restorers, consulting engineers, designers and other professionals dealing with cultural heritage and sustainable development. Also graduate students in applied geo-science (mineralogy, geochemistry, petrology), architecture and civil engineering will find interesting information in this book.
