The previously untold story of the Zenith Trans-Oceanic, the world's most romantic and expensive series of portable radios, now in a newly revised & expanded edition. Long a companion of kings, presidents, transoceanic yachtsmen and world explorers, the Trans-Oceanic was also carried into battle by American troops in three wars. Its great popularity in spite of a very high price can be laid at the feet of several generations of armchair travelers who used the shortwave capabilities of the Trans-Oceanic as a window on the world. With access to the Zenith corporate archives and their long experience as radio enthusiasts and writers for both the popular and scholarly press, Professors Bryant and Cones present the engrossing stories of the development and use of the Trans-Oceanic throughout its forty year life. They present a wealth of never-before published photographs, documents and information concerning these fascinating radios, their collection, preservation and restoration.

Elizabeth DeLoughrey invokes the cyclical model of the continual movement and rhythm of the ocean (‘tidalectics’) to destabilize the national, ethnic, and even regional frameworks that have been the mainstays of literary study. The result is a privileging of alter/native epistemologies whereby island cultures are positioned where they should have been all along—at the forefront of the world historical process of transoceanic migration and landfall. The research, determination, and intellectual dexterity that infuse this nuanced and meticulous reading of Pacific and Caribbean literature invigorate and deepen our interest in and appreciation of island literature. —Vilsoni Hereniko, University of Hawai‘i "Elizabeth DeLoughrey brings contemporary hybridity, diaspora, and globalization theory to bear on ideas of indigeneity to show the complexities of ‘native’ identities and rights and their grounded opposition as ‘indigenous regionalism’ to free-floating globalized cosmopolitanism. Her models are instructive for all postcolonial readers in an age of transnational migrations." —Paul Sharrad, University of Wollongong, Australia Routes and Roots is the first comparative study of Caribbean and Pacific Island literatures and the first work to bring indigenous and diaspora literary studies together in a sustained dialogue. Taking the "tidalectic" between land and sea as a dynamic starting point, Elizabeth DeLoughrey foregrounds geography and history in her exploration of how island writers inscribe the complex relation between routes and roots. The first section looks at the sea as history in literatures of the Atlantic middle passage and Pacific Island voyaging, theorizing the transoceanic imaginary. The second section turns to the land to examine indigenous epistemologies in nation-building literatures. Both sections are particularly attentive to the ways in which the metaphors of routes and roots are gendered, exploring how masculine travelers are naturalized through their voyages across feminized lands and seas. This methodology of charting transoceanic migration and landfall helps elucidate how theories and people travel, positioning island cultures in the world historical process. In fact, DeLoughrey demonstrates how these tropical island cultures helped constitute the very metropoles that deemed them peripheral to modernity. Fresh in its ideas, original in its approach, Routes and Roots engages broadly with history, anthropology, and feminist, postcolonial, Caribbean, and Pacific literary and cultural studies. It productively traverses diaspora and indigenous studies in a way that will facilitate broader discussion between these often segregated disciplines.
These two volumes, Zenith Radio, The Glory Years, 1936-1945, tell the story and highlight the products of the Zenith Radio Corporation between the early years (1919-1935) and the end of World War II. History and Product begins with an exploration of the history of the corporation from 1936-1945 in a profusely researched and illustrated way. It continues with color photographic portraits of outstanding examples of many of the products manufactured by Zenith in this period, providing a visual survey of the wide range of Zenith radios produced during the Glory Years. The Illustrated Catalog and Database includes a catalog that gathers the most complete collection of Zenith images ever published, followed by a Database which is the most complete listing of Zenith products. In addition, appendices to this volume include Commander Eugene MacDonald's Presidential speeches, information on telepathy experiments at Zenith, Zenith in the movies, and Zenith Annual Reports from 1936-1945. All told these two volumes represent a treasure trove for radiophiles in general and Zenith fans and historians in particular.
Covering the tabletop battery radios built by Zenith, the Chicago-based manufacturer, each radio is described in detail. Included are comprehensive functional descriptions on each set's operation, which uses color-coded diagrams to aid in describing the circuits. Over 400 color photos and over 200 diagrams illustrate the thorough text. Each radio section includes a Quick Reference Guide. Previously unpublished information related to these radios is included for the first time. The restoration section covers the reproduction of vital replacement parts (pointers, pulleys, etc.) that typically need replacing, the repair of other parts (variable capacitor, transformers, etc.), appropriate modifications (battery adapter, etc.), and testing in order to get that early radio working. The techniques presented can be applied to the restoration of any 1920s radio. Also included are instructions on reproducing any battery ("A", "B", or "C") in radios built in the 1920s. This is an indispensable reference guide to early Zenith radios.
Saharan trade has been much debated in modern times, but the main focus of interest remains the medieval and early modern periods, for which more abundant written sources survive. The pre-Islamic origins of Trans-Saharan trade have been hotly contested over the years, mainly due to a lack of evidence. Many of the key commodities of trade are largely invisible archaeologically, being either of high value like gold and ivory, or organic like slaves and textiles or consumable commodities like salt. However, new research on the Libyan people known as the Garamantes and on their trading partners in the Sudan and Mediterranean Africa requires us to revise our views substantially. In this volume experts re-assess the evidence for a range of goods, including beads, textiles, metalwork and glass, and use it to paint a much more dynamic picture, demonstrating that the pre-Islamic Sahara was a more connected region than previously thought.
The proliferation of harmful phytoplankton in marine ecosystems can cause massive fish kills, contaminate seafood with toxins, impact local and regional economies and dramatically affect ecological balance. Real-time observations are essential for effective short-term operational forecasting, but observation and modelling systems are still being developed. This volume provides guidance for developing real-time and near real-time sensing systems for observing and predicting plankton dynamics, including harmful algal blooms, in coastal waters. The underlying theory is explained and current trends in research and monitoring are discussed.Topics covered include: coastal ecosystems and dynamics of harmful algal blooms; theory and practical applications of in situ and remotely sensed optical detection of microalgal distributions and composition; theory and practical applications of in situ biological and chemical sensors for targeted species and toxin detection; integrated observing systems and platforms for detection; diagnostic and predictive modelling of ecosystems and harmful algal blooms, including data assimilation techniques; observational needs for the public and government; and future directions for research and operations.
