De-Bug: Voices from the Underside of Silicon Valley
by Raj Jayadev and Jean MelesaineStories of the dot-com boom—from everyone but the techies. “A raw look into the lives of residents bearing the brunt of gentrification.” —HuffPostNo shuttle buses here: De-Bug, a new collection of true stories from the social justice organization of the same name, shows a side of working in Silicon Valley that you won’t read about in the business section. As tech moguls land the cover of Forbes, the South Bay’s working class is making ends meet as metal scrappers, factory workers, club bouncers, hairstylists, rickshaw drivers, ice cream cart pushers. The stories in De-Bug are poignant, often very funny accounts of bootstrapping in the land of angel investors and thought leaders. A construction worker predicts which of his customers are about to strike it rich and which are on the edge of bankruptcy based on the states of their swimming pools. A “secondhand hustler” travels the garage sale-flea market circuit in search of treasures to resell online. A temp worker at a medical device manufacturer sells his blood, at the company’s request, to test the equipment. These storytellers are frank when discussing their own flaws, but are equally up-front about the rigged system in which they operate.Disruptive in the truest sense of the word, De-Bug offers valuable insight into California’s latest boomtown.“Silicon Valley’s less-noticed denizens show an unexpected knack for grace, wit, and survival.” —Kentaro Toyama, author of Geek Heresy“If you truly want to know Silicon Valley, in all of its complexity, then De-Bug is a must-read.” —Tomás Jiménez, associate professor of sociology, Stanford University
De-Convergence of Global Media Industries: De-convergence Of Global Media Industries (Routledge Research in Cultural and Media Studies #47)
by Dal Yong JinConvergence has become a buzzword, referring on the one hand to the integration between computers, television, and mobile devices or between print, broadcast, and online media and on the other hand, the ownership of multiple content or distribution channels in media and communications. Yet while convergence among communications companies has been the major trend in the neoliberal era, the splintering of companies, de-convergence, is now gaining momentum in the communications market. As the first comprehensive attempt to analyze the wave of de-convergence of the global media system in the context of globalization, this book makes sense of those transitions by looking at global trends and how global media firms have changed and developed their business paradigm from convergence to de-convergence. Jin traces the complex relationship between media industries, culture, and globalization by exploring it in a transitional yet contextually grounded framework, employing a political economic analysis integrating empirical data analysis.
De-Extinction: The Science of Bringing Lost Species Back to Life
by Rebecca E. HirschIn the twenty-first century, because of climate change and other human activities, many animal species have become extinct, and many others are at risk of extinction. Once they are gone, we cannot bring them back—or can we? With techniques such as cloning, scientists want to reverse extinction and return lost species to the wild. Some scientists want to create clones of recently extinct animals, while others want to make new hybrid animals. Many people are opposed to de-extinction. Some critics say that the work diverts attention from efforts to save species that are endangered. Others say that de-extinction amounts to scientists "playing God." Explore the pros and cons of de-extinction and the cutting-edge science that makes it possible.

by Greg BearFrom a New York Times–bestselling author: A new kind of phone awakens the dead in this technological horror novel “reminiscent of Koontz at his best” (Booklist). Ever since his life was shattered by the kidnapping and murder of his young daughter, Peter Russell has become a ghost of a man. Once a successful director of adult films, he has been reduced to running questionable errands for an eccentric California millionaire. But everything changes when a Los Angeles start-up offers him the opportunity to create promotional videos for their revolutionary new technology, Trans. The product offers exceptionally powerful, crystal-clear mobile communication that can operate anywhere and everywhere—and Peter sets out to put it into every palm. But as he uses the device himself, he starts to see his murdered little girl . . . Soon, there are other voices—disembodied, confused, angry—emanating from a newly invaded dimension. Many are even malevolent . . . and hungry . . . and deadly. As the death toll of Trans-users skyrockets, Peter’s life begins a new spiral downward. Now, he must race to make sense of the horror Trans has wrought before the gateway to Hell bursts wide open. With Dead Lines, author of the Eon series Greg Bear transforms the literary realm of Dean Koontz, Peter Straub, and Stephen King into something unique by ingeniously blending the speculative with the supernatural.

Dead Pool: Lake Powell, Global Warming, And The Future Of Water In The West
by James Lawrence PowellWhere will the water come from to sustain the great desert cities of Las Vegas, Los Angeles, and Phoenix? In a provocative exploration of the past, present, and future of water in the West, James Lawrence Powell begins at Lake Powell, the vast reservoir that has become an emblem of this story. At present, Lake Powell is less than half full. Bathtub rings ten stories tall encircle its blue water; boat ramps and marinas lie stranded and useless. To refill it would require surplus water―but there is no surplus: burgeoning populations and thirsty crops consume every drop of the Colorado River. Add to this picture the looming effects of global warming and drought, and the scenario becomes bleaker still. Dead Pool, featuring rarely seen historical photographs, explains why America built the dam that made Lake Powell and others like it and then allowed its citizens to become dependent on their benefits, which were always temporary. Writing for a wide audience, Powell shows us exactly why an urgent threat during the first half of the twenty-first century will come not from the rising of the seas but from the falling of the reservoirs.

Dead Tree Media: Manufacturing the Newspaper in Twentieth-Century North America (Hagley Library Studies in Business, Technology, and Politics)
by Michael StammA deep and timely account of how American newspapers were produced and distributed on paper.Winner of the Best Book in Canadian Business History by the Canadian Business History AssociationPopular assessments of printed newspapers have become so grim that some have taken to calling them "dead tree media" as a way of invoking the medium’s imminent demise. There is a literal truth hidden in this dismissive expression: printed newspapers really are material goods made from trees. And, throughout the twentieth century, the overwhelming majority of trees cut down in the service of printing newspapers in the United States came from Canada. In Dead Tree Media, Michael Stamm reveals the international history of the commodity chains connecting Canadian trees and US readers. Drawing on newly available corporate documents and research in archives across North America, Stamm offers a sophisticated rethinking of the material history of the printed newspaper. Tracing its industrial production from the forest to the newsstand, he provides an account of the obscure and often hidden labor involved in this manufacturing process by showing how it was driven by not only publishers and journalists but also lumberjacks, paper mill workers, policymakers, chemists, and urban and regional planners. Stamm describes the 1911 shift in tariff policy that gave US publishers duty-free access to Canadian newsprint, providing a tremendous boost to Canadian paper manufacturers and a significant subsidy to American newspaper publishers. He also explains how Canada attracted massive American foreign investment in paper mills around the same time that US publishers were able to gain greater access to Canada’s vast spruce forests. Focusing particularly on the Chicago Tribune, Stamm provides a new history of the rise and fall of both the mass circulation printed newspaper and the particular kind of corporation in the newspaper business that had shaped many aspects of the cultural, political, and even physical landscape of North America. For those seeking to understand the travails of the contemporary newspaper business, Dead Tree Media is essential reading.
