In studying the history of the vernacular in worship beginning with the Christian Scriptures, Dynamic Equivalence uncovers the power of a living language to transform communities of faith. How we pray when we come together for common worship has always been significant, but the issue of liturgical language received unprecedented attention in the twentieth century when Latin Rite Roman Catholic worship was opened to the vernacular at Vatican II. Worshiping in one's native tongue continues to be of issue as the churches debate over what type of vernacular should be employed. Dynamic Equivalence traces the history of liturgical language in the Western Christian tradition as a dynamic and living reality. Particular attention is paid to the twentieth century Vernacular Society within the United States and how the vernacular issue was treated at Vatican II, especially within an ecumenical context. The first chapter offers a short history of the vernacular from the first century through the twentieth. The second and third chapters contain a significant amount of archival material, much of which has never been published before. These chapters tell the story of a mixed group of Catholic laity and clergy dedicated to promoting the vernacular during the first half of the twentieth century. Chapter Four begins with a survey of vernacular promotion in the Reformation itself, explores the issue of vernacular worship as an instrument of ecumenical hospitality and concludes with some examples of ecumenical liturgical cooperation in the years immediately preceding the Council. The final chapter treats the vernacular debate at the Council with attention to the Vernacular Society's role in helping with theimplementation of the vernacular. Chapters are "A Brief History of the Vernacular," "The Origins of the Vernacular Society: 1946-1956," "Pressure for the Vernacular Mounts: 1956-1962," "Vernacular Worship and Ecumenical Exchange," "Vatican II and the Vindication of the Vernacular: 1962-1965" Keith F. Pecklers, SJ, SLD, is professor of liturgy at the Pontifical Gregorian University in Rome and professor of liturgical history at the Pontifical Liturgical Institute of Sant 'Anselmo. He is the author of The Unread Vision: The Liturgical Movement in the United States of America 1926-1955, and co-editor of Liturgy for the New Millennium: A Commentary on the Revised Sacramentary, published by The Liturgical Press.

Drawing on a wide range of mathematical disciplines, including geometry, analysis, applied mathematics and algebra, this book presents an innovative synthesis of methods used to study problems of equivalence and symmetry which arise in a variety of mathematical fields and physical applications. Systematic and constructive methods for solving equivalence problems and calculating symmetries are developed and applied to a wide variety of mathematical systems, including differential equations, variational problems, manifolds, Riemannian metrics, polynomials and differential operators. Particular emphasis is given to the construction and classification of invariants, and to the reductions of complicated objects to simple canonical forms. This book will be a valuable resource for students and researchers in geometry, analysis, algebra, mathematical physics and other related fields.

MAGA hats, pussy hats. Hijabs, handmaids' bonnets. Safe spaces, safe streets. Voter fraud, voter suppression. George Soros, the Koch Brothers. Live free or die, no justice no peace. See any similarities? If so, you've just violated rule No.1 of turbo-partisan America: That no matter how closely one side's position, pet hate, personal taste, or language mirrors the other's, any claim of left-right equivalence is patently false, and probably deeply offensive. But what if the false equivalence isn't actually false, and what both sides really need is a bracing slap of refined bothsiderism? The Little Book of Left-Right Equivalence is that slap, a no-holds-barred catalog of interchangeable idiocies, double dual-standards, and two-way u-turns that shows no favor and takes no prisoners. Set in short couplets rather than traditional book prose, and offering an unusual mix of serious and satirical - and highbrow and lowbrow - it is guaranteed to outrage, delight and enlighten.

Since the subject of Groups of Self-Equivalences was first discussed in 1958 in a paper of Barcuss and Barratt, a good deal of progress has been achieved. This is reviewed in this volume, first by a long survey article and a presentation of 17 open problems together with a bibliography of the subject, and by a further 14 original research articles.

Stimulus Equivalence for Students with Developmental Disabilities provides a step-by-step program for converting lesson plans into equivalence-based instruction. Using language and tools accessible to both students and practitioners, chapters present the concept of equivalence-based instruction and include clear and concise procedural descriptions, as well as data sheets and PowerPoint slides, with replaceable stimuli, so that special educators and clinicians will be able to immediately implement this procedure to teach any academic skill. Written in engaging prose with an emphasis on practical application, this book is an essential resource for special educators and graduate students studying to become BCBAs and special educators.

FINALIST FOR THE NATIONAL BOOK CRITICS CIRCLE AWARD In 1960, Harvard’s sister college, Radcliffe, announced the founding of an Institute for Independent Study, a “messy experiment” in women’s education that offered paid fellowships to those with a PhD or “the equivalent” in artistic achievement. Five of the women who received fellowships—poets Anne Sexton and Maxine Kumin, painter Barbara Swan, sculptor Marianna Pineda, and writer Tillie Olsen—quickly formed deep bonds with one another that would inspire and sustain their most ambitious work. They called themselves “the Equivalents.” Drawing from notebooks, letters, recordings, journals, poetry, and prose, Maggie Doherty weaves a moving narrative of friendship and ambition, art and activism, love and heartbreak, and shows how the institute spoke to the condition of women on the cusp of liberation. “Rich and powerful. . . . A love story about art and female friendship.” —Harper’s Magazine “Reads like a novel, and an intense one at that. . . . The Equivalents is an observant, thoughtful and energetic account.” —Margaret Atwood, The Globe and Mail (Toronto)
