The polar regions (the Arctic and Antarctic) have enjoyed widespread public attention in recent years, as issues of conservation, sustainability, resource speculation and geopolitical manoeuvring have all garnered considerable international media inter
Complete with reference tables and sample problems, this volume serves as a textbook or reference for solid-state physics and chemistry, materials science, and engineering. Chapters illustrate symmetry, and its role in determining solid properties, as well as a demonstration of group theory.
This graduate-level text presents the fundamental physics of solid-state lasers, including the basis of laser action and the optical and electronic properties of laser materials. After an overview of the topic, the first part begins with a review of quantum mechanics and solid-state physics, spectroscopy, and crystal field theory; it then treats the quantum theory of radiation, the emission and absorption of radiation, and nonlinear optics; concluding with discussions of lattice vibrations and ion-ion interactions, and their effects on optical properties and laser action. The second part treats specific solid-state laser materials, the prototypical ruby and Nd-YAG systems being treated in greatest detail; and the book concludes with a discussion of novel and non-standard materials. Some knowledge of quantum mechanics and solid-state physics is assumed, but the discussion is as self-contained as possible, making this an excellent reference, as well as useful for independent study.
The African diaspora a direct result of the transatlantic slave trade and Western colonialism has generated a wide array of artistic achievements, from blues and reggae, to the paintings of the pioneering African American artist Henry Ossawa Tanner and video creations of contemporary hip-hop artists. This book concentrates on how these works, often created during times of major social upheaval and transformation, use black culture both as a subject and as context. From musings on the souls of black folk in late nineteenth-century art, to questions of racial and cultural identities in performance, media, and computer-assisted arts in the twenty-first century, this book examines the philosophical and social forces that have shaped a black presence in modern and contemporary visual culture. Now updated, this new edition helps us understand better how the first two decades of the twenty-first century have been a transformative moment in which previous assumptions about race, difference, and identity have been irrevocably altered, with art providing a useful lens through which to think about these compelling issues.

This important new biography of Elgar draws on letters and documents which have become available in the last twenty-five years. Michael Kennedy, a leading scholar of British music and a distinguished musical biographer, uses this new material, which includes Elgar's own vast correspondence, in an attempt to get to the centre of the composer's complex personality. Elgar's letters reveal his unpredictable swings of mood, from gaiety and a fondness for puns to morose self-pity and a feeling that he was 'not wanted'.

Long a fruitful area of scrutiny for students of organizations, the study of institutions is undergoing a renaissance in contemporary social science. This volume offers, for the first time, both often-cited foundation works and the latest writings of scholars associated with the "institutional" approach to organization analysis. In their introduction, the editors discuss points of convergence and disagreement with institutionally oriented research in economics and political science, and locate the "institutional" approach in relation to major developments in contemporary sociological theory. Several chapters consolidate the theoretical advances of the past decade, identify and clarify the pa...
