Radio telescopes as well as communication antennas operate under the influence of gravity, temperature and wind. Among those, temperature influences may degrade the performance of a radio telescope through transient changes of the focus, pointing, path length and sensitivity, often in an unpredictable way. Thermal Design and Thermal Behaviour of Radio Telescopes and their Enclosures reviews the design and construction principles of radio telescopes in view of thermal aspects and heat transfer with the variable thermal environment; it explains supporting thermal model calculations and the application and efficiency of thermal protection and temperature control; it presents many measurements illustrating the thermal behaviour of telescopes in the environment of their observatory sites. The book benefits scientists and radio/communication engineers, telescope designers and construction firms as well as telescope operators, observatory staff, but also the observing astronomer who is directly confronted with the thermal behaviour of a telescope.
This book discusses how Public-Private Partnership (PPP) is practiced in developed and developing economies. The book demonstrates how PPP as a concept has grown over the years with many governments particularly from developing economies/countries seeking to enhance infrastructure growth and development through this scheme. Further, the book explores how PPP has become the major infrastructure procurement policy adopted by many governments globally to address the rapid increase in demand for infrastructure due to the increase in population growth. Although, there are many available textbooks on PPP, this book is unique because it provides in-depth analysis and discussion on the international best practices of PPP from developed and developing economies perspectives. This book provides strategic measures, useful practices and information about the similarities and differences in PPP practices in developed and developing economies based on empirical evidence and case studies. This book is structured in nine chapters. The first chapter explores the basic concept of PPPs. The second chapter looks at the global development and practices of PPP particularly from developed and developing economies’ perspectives. The third to the eight chapters explores critical topics and issues in international PPP practices from developed and developing economies perspectives. The topics included in this book are: governments motivations for adopting PPPs, barriers to PPP implementation, measuring PPP project success, risk management in PPPs, causes of conflict and conflict resolution mechanisms in PPPs and management of unsolicited proposals. The ninth chapter presents a comprehensive best practice framework for implementing international PPP projects. This book is useful to undergraduate and postgraduate students in architecture, civil engineering, business, construction and project management, researchers interested in PPP topics, international investors and financiers, public authorities and departments and international development banks. This book provides in-depth insights and understanding on the best practices for PPP from the international perspective especially from the viewpoint of countries with diverse culture and policies. Importantly, readers will be adequately informed of the similarities and differences of PPP practices and processes in developed and developing economies based on empirical evidence. Investors and governments will be informed of the strategic plans and preventive actions to employ when engaging in PPP arrangements in any part of the world.
In the 1930's, great rolling walls of dust swept across the Great Plains. The storms buried crops, blinded animals, and suffocated children. It was a catastrophe that would change the course of American history as people struggled to survive in this hostile environment, or took the the roads as Dust Bowl refugees. Here, in riveting, accessible prose, and illustrated with moving historical quotations and photographs, acclaimed historian Albert Marrin explains the causes behind the disaster and investigates the Dust Bowl's imact on the land and the people. Both a tale of natural destruction and a tribute to those who refused to give up, this is a beautiful exploration of an important time in our country's past.
This analysis of the historical evolution and contemporary form of the system of world politics utilizes contemporary theories and debates in sociology and global history. Critically reflecting also on world politics in the field of international relations, this book will appeal to a wide readership in a range of fields.
Illuminating the troublesome and disturbing aspects of workplace diversity that tend to be glossed over in most management literature, Managing the Organizational Melting Pot covers key issues such key as: individual and institutional resistance, the effectiveness of diversity change efforts, and the less visible ways in which exclusion and discrimination continue to be practiced in the workplace. To assist the reader in understanding some of these dilemmas, the contributors to this collection adopt an array of theoretical frameworks, that are all striking departures from traditional and more functional perspectives on diversity. The volume also employs a variety of theoretical perspectives, including intergroup relations theory, critical theory, Jungian psychology, feminism, post-colonial theory, cultural history, postmodernism, realism, institutional theory, and class analysis. Further, the authors examine a multitude of organizational situations in which the complications of diversity surface-many of which cross race, gender, ethnic and other socially constructed boundaries. Managing the Organizational Melting Pot draws examples not only from the United States , but also looks at situations from Canada, Britain, and the Middle East. Students, scholars, and managers who want to prepare themselves to deal with the challenges presented by a multicultural workforce will find this beneficial reading. In addition, researchers interested in conducting research in diversity management will find this an up-to-date, thought-provoking resource.
Art for art's sake. Art created in pursuit of personal expression. In Art in an Age of Counterrevolution, Albert Boime rejects these popular modern notions and suggests that history—not internal drive or expressive urge—as the dynamic force that shapes art. This volume focuses on the astonishing range of art forms currently understood to fall within the broad category of Romanticism. Drawing on visual media and popular imagery of the time, this generously illustrated work examines the art of Romanticism as a reaction to the social and political events surrounding it. Boime reinterprets canonical works by such politicized artists as Goya, Delacroix, Géricault, Friedrich, and Turner, framing their work not by personality but by its sociohistorical context. Boime's capacious approach and scope allows him to incorporate a wide range of perspectives into his analysis of Romantic art, including Marxism, social history, gender identity, ecology, structuralism, and psychoanalytic theory, a reach that parallels the work of contemporary cultural historians and theorists such as Edward Said, Pierre Bourdieu, Eric Hobsbawm, Frederic Jameson, and T. J. Clark. Boime ultimately establishes that art serves the interests and aspirations of the cultural bourgeoisie. In grounding his arguments on their work and its scope and influence, he elucidates how all artists are inextricably linked to history. This book will be used widely in art history courses and exert enormous influence on cultural studies as well.
This book integrates and assesses the vast and rapidly growing literature on strategic leadership, which is the study of top executives and their effects on organizations. The basic premise is that in order to understand why organizations do the things they do, or perform the way they do, we need to deeply comprehend the people at the top-- their experiences, abilities, values, social connections, aspirations, and other human features. The actions--or inactions--of a relatively small number of key people at the apex of an organization can dramatically affect organizational outcomes. The scope of strategic leadership includes individual executives, especially chief executive officers (CEOs), groups of executives (top management teams, or TMTs); and governing bodies (particularly boards of directors). Accordingly, the book addresses an array of topics regarding CEOs (e.g., values, personality, motives, demography, succession, and compensation); TMTs (including composition, processes, and dynamics); and boards of directors (why boards look and behave the way they do, and the consequences of board profiles and behaviors). Strategic Leadership synthesizes what is known about strategic leadership and indicates new research directions. The book is meant primarily for scholars who strive to assess and understand the phenomena of strategic leadership. It offers a considerable foundation on which professionals involved in executive search, compensation, appraisal and staffing, as well as board members who evaluate executive performance and potential, might build their tools and perspectives.
Interest in green chemistry and clean processes has grown so much in recent years that topics such as fluorous biphasic catalysis, metal organic frameworks, and process intensification, which were barely mentioned in the First Edition, have become major areas of research. In addition, government funding has ramped up the development of fuel cells and biofuels. This reflects the evolving focus from pollution remediation to pollution prevention. Copiously illustrated with more than 800 figures, the Third Edition provides an update from the frontiers of the field. It features supplementary exercises at the end of each chapter relevant to the chemical examples introduced in each chapter. Particular attention is paid to a new concluding chapter on the use of green metrics as an objective tool to demonstrate proof of synthesis plan efficiency and to identify where further improvements can be made through fully worked examples relevant to the chemical industry. NEW AND EXPANDED RESEARCH TOPICS Metal-organic frameworks Metrics Solid acids for alkylation of isobutene by butanes Carbon molecular sieves Mixed micro- and mesoporous solids Organocatalysis Process intensification and gas phase enzymatic reactions Hydrogen storage for fuel cells Reactive distillation Catalysts in action on an atomic scale UPDATED AND EXPANDED CURRENT EVENTS TOPICS Industry resistance to inherently safer chemistry Nuclear power Removal of mercury from vaccines Removal of mercury and lead from primary explosives Biofuels Uses for surplus glycerol New hard materials to reduce wear Electronic waste Smart growth The book covers traditional green chemistry topics, including catalysis, benign solvents, and alternative feedstocks. It also discusses relevant but less frequently covered topics with chapters such as "Chemistry of Long Wear" and "Population and the Environment." This coverage highlights the importance of chemistry to everyday life and demonstrates the benefits the expanded exploitation of green chemistry can have for society.
From the Internet to networks of friendship, disease transmission, and even terrorism, the concept--and the reality--of networks has come to pervade modern society. But what exactly is a network? What different types of networks are there? Why are they interesting, and what can they tell us? In recent years, scientists from a range of fields--including mathematics, physics, computer science, sociology, and biology--have been pursuing these questions and building a new "science of networks." This book brings together for the first time a set of seminal articles representing research from across these disciplines. It is an ideal sourcebook for the key research in this fast-growing field. The book is organized into four sections, each preceded by an editors' introduction summarizing its contents and general theme. The first section sets the stage by discussing some of the historical antecedents of contemporary research in the area. From there the book moves to the empirical side of the science of networks before turning to the foundational modeling ideas that have been the focus of much subsequent activity. The book closes by taking the reader to the cutting edge of network science--the relationship between network structure and system dynamics. From network robustness to the spread of disease, this section offers a potpourri of topics on this rapidly expanding frontier of the new science.
A comprehensive study of the clarinet in use through the classical period, 1760 to 1830, a period of intensive musical experimentation. The book provides a detailed review and analysis of construction, design, materials, and makers of clarinets. Rice also explores how clarinet construction and performance practice developed in tandem with the musical styles of the period.
Australians have become increasingly visible outside of the country as speakers and actors in radio and television, their media moguls have frequently bought up foreign companies, and people around the world have been able to enjoy such Australian productions as The Flying Doctors, Neighbours, and Kath and Kim. The origins, early development, and later adaptations of radio and television show how Australia has gone from being a minor and rather parochial player to being a significant part of the international scene. The A to Z of Australian Radio and Television provides essential facts and information concerning the Australian radio and television industry. This is accomplished through the use of a chronology, an introductory essay, a bibliography, and hundreds of cross-referenced dictionary entries on directors, producers, writers, actors, television and radio series, and television and radio stations.
