The free-standing radios of the middle decades of the 20th century were invitingly rotund and proudly displayed??????nothing like today's skinny televisions hidden inside "entertainment centers." Radios were the hub of the family's after-dinner activities, and children and adults gorged themselves on western-adventure series like "The Lone Ranger," police dramas such as "Calling All Cars," and the varied offerings of "The Cavalcade of America." Shows often aired two or three times a week, and many programs were broadcast for more than a decade, comprising hundreds of episodes. This book includes more than 300 program logs (many appearing in print for the first time) drawn from newspapers, script files in broadcast museums, records from NBC, ABC and CBS, and the personal records of series directors. Each entry contains a short broadcast history that includes directors, writers, and actors, and the broadcast dates and airtimes. A comprehensive index rounds out the work.
"It is difficult to imagine a subject with more elusive data than this. The source and location of clandestine radio broadcasts are, by definition, secret. `White' stations openly identify themselves (such as Radio Free Europe), and `gray' stations are purportedly operated by dissident groups within a country, although actually they might be located in another nation; but `black' stations transmit broadcasts by one side disguised as broadcasts by another. . . . [This] is an extraordinary book. It belongs in every research library concerned with war and revolution and international communications. A valuable appendix lists known clandestine radio stateions, 1948-1985." Choice "In this ambitious and impressive study two academic specialists in the field of political communication have endeavored to cover the history of such broadcasts from the beginnings in the 1930s through the use of psychological warfare and deception of World War II to the manifold practice of `gray' and `black' propaganda that had punctuated the conflict of the postwar period."

Essentials of Pediatric Radiology: A Multimodality Approach provides a concise overview of both basic and complex topics encountered by pediatric radiologists in their daily practice. Written by leading pediatric radiologists from renowned children's hospitals, it focuses particularly on multimodality imaging, covering the full gamut of radiologic diagnostic techniques, including conventional radiography and ultrasound, Doppler ultrasound, up-to-date CT and MRI techniques, and PET-CT. Each chapter is generously illustrated with high quality images, as well as graphs, tables, decision flowcharts and featured cases. Chapters are arranged according to pathologies, rather than organ systems, providing the reader with clinically-oriented information when employing 'whole body' techniques or analysing scans involving multiple anatomical sites. The book is complemented by an outstanding free access website of sample cases containing questions and answers that enable readers to test their diagnostic proficiency - see http://essentials-of-pediatric-radiology.com. A key text for pediatric radiology fellows, radiology residents and general radiologists, this is also essential reading for all pediatricians.
Twentieth-century Canada fostered a range of great minds, but the country's diversity and wide range of academic fields have led to their ideas being portrayed as the work of isolated thinkers. Canadian Idealism and the Philosophy of Freedom contests this assumption by linking the works of C.B. Macpherson, George Grant, and Charles Taylor to demonstrate the presence of a Canadian intellectual tradition.
the wave theory foundations of today's radio occultation techniques<br> <br> Forty years ago, the premier radio occultation problem was how to profile the atmosphere and radius of Mars using signals sent by the Mariner 4 spacecraft. Researchers then could rely on ray theory-based techniques for accurate analysis of the thin, uniform Martian atmosphere. Today's radio occultation challenges mostly involve communications platforms-and related data, instrument systems, and applications-in the Earth's own atmosphere. To deal with the density and complexity of this multilayered medium, an analytical framework that goes beyond ray theory is needed.<br> <br> Setting the cutting edge for the field, Radio Occultations Using Earth Satellites: A Wave Theory Treatment develops a purely wave-theoretic approach to occultation analysis. This approach yields more nuanced results than either ray or hybrid (ray/wave) methodologies offer, and proves suitable for the many variables at work in today's problems.<br> <br> This groundbreaking text provides:<br> * An introduction to the general theory of radio occultations<br> * Development of ray theory and scalar diffraction treatments of radio propagation processes<br> * Development of a wave theoretic treatment of the above wave propagation processes<br> * The correspondence between wave and ray theories<br> * A discussion of how to use a wave-theoretic approach to infer the refractive properties of the propagation medium from a time series set of observations of the propagated wave's phase and amplitude<br> <br> A comprehensive resource that clearly defines the latest topics and methodologies, Radio Occultations Using Earth Satellites is a must-have text for engineers, scientists, students, and managers in satellites communications, navigation, deep space and planetary exploration, aerospace, atmospheric science, physics, and engineering.<br> <br> The Deep Space Communications and Navigation Series is authored by scientists and engineers with extensive experience in astronautics, communications, and related fields. It lays the foundation for innovation in the areas of deep space navigation and communications by disseminating state-of-the-art knowledge in key technologies.
