Cognitive Radio Mobile Ad Hoc Networks
by F. Richard YuCognitive radios (CR) technology is capable of sensing its surrounding environment and adapting its internal states by making corresponding changes in certain operating parameters. CR is envisaged to solve the problems of the limited available spectrum and the inefficiency in the spectrum usage. CR has been considered in mobile ad hoc networks (MANETs), which enable wireless devices to dynamically establish networks without necessarily using a fixed infrastructure. The changing spectrum environment and the importance of protecting the transmission of the licensed users of the spectrum mainly differentiate classical MANETs from CR-MANETs. The cognitive capability and re-configurability of CR-MANETs have opened up several areas of research which have been explored extensively and continue to attract research and development. The book will describe CR-MANETs concepts, intrinsic properties and research challenges of CR-MANETs. Distributed spectrum management functionalities, such as spectrum sensing and sharing, will be presented. The design, optimization and performance evaluation of security issues and upper layers in CR-MANETs, such as transport and application layers, will be investigated.
Cognitive Radio, Mobile Communications and Wireless Networks (EAI/Springer Innovations in Communication and Computing)
by Mubashir Husain Rehmani Riadh DhaouThis book provides an overview of the latest research and development of new technologies for cognitive radio, mobile communications, and wireless networks. The contributors discuss the research and requirement analysis and initial standardization work towards 5G cellular systems and the capacity problems it presents. They show how cognitive radio, with the capability to flexibly adapt its parameters, has been proposed as the enabling technology for unlicensed secondary users to dynamically access the licensed spectrum owned by legacy primary users on a negotiated or an opportunistic basis. They go on to show how cognitive radio is now perceived in a much broader paradigm that will contribute to solve the resource allocation problem that 5G requirements raise. The chapters represent hand-selected expanded papers from EAI sponsored and hosted conferences such as the 12th EAI International Conference on Mobile and Ubiquitous Systems, the 11th EAI International Conference on Heterogeneous Networking for Quality, Reliability, Security and Robustness, the 10th International Conference on Cognitive Radio Oriented Wireless Networks, the 8th International Conference on Mobile Multimedia Communications, and the EAI International Conference on Software Defined Wireless Networks and Cognitive Technologies for IoT.

The Cognitive Style Of PowerPoint: Pitching Out Corrupts Within
by Edward TufteIn corporate and government bureaucracies, the standard method for making a presentation is to talk about a list of points organized onto slides projected up on the wall. For many years, overhead projectors lit up transparencies, and slide projectors showed high-resolution 35mm slides. Now 'slideware' computer programs for presentations are nearly everywhere. Early in the 21st century, several hundred million copies of Microsoft PowerPoint were turning out trillions of slides each year. Unfortunately, slideware often reduces the analytical quality of presentations. In particular, the popular PowerPoint templates (ready-made designs) usually weaken verbal and spatial reasoning, and almost always corrupt statistical analysis. The author examines how these problems can be avoided and how to improve Powerpoint (and other) presentations.

Coherence, Continuity, and Cohesion: Theoretical Foundations for Document Design (Routledge Communication Series)
by Kim Sydow CampbellThere is a need for general theoretical principles describing/explaining effective design -- those which demonstrate "unity" and enhance comprehension and usability. Theories of cohesion from linguistics and of comprehension in psychology are likely sources of such general principles. Unfortunately, linguistic approaches to discourse unity have focused exclusively on semantic elements such as synonymy or anaphora, and have ignored other linguistic elements such as syntactic parallelism and phonological alliteration. They have also overlooked the non-linguistic elements -- visual factors such as typography or color, and auditory components such as pitch or duration. In addition, linguistic approaches have met with criticism because they have failed to explain the relationship between semantic cohesive elements and coherence. On the other hand, psychological approaches to discourse comprehension have considered the impact of a wider range of discourse elements -- typographical cuing of key terms to enhance comprehension -- but have failed to provide general theoretical explanations for such observations. This volume uses Gestalt theory to provide general principles for predicting one aspect of coherence -- that of continuity -- across the entire range of discourse elements, and also to outline the relationship between cohesion and coherence. The theoretical core of this book argues that the cognitive principles that explain why humans "sense" unity in a succession of sounds (a whole musical piece) or in a configuration of visual shapes (a complete object) are the basis of principles which explain why we "sense" unity in oral, written, and electronically produced documents.
Cokie: A Life Well Lived
by Steven V. RobertsThe extraordinary life and legacy of legendary journalist Cokie Roberts—a trailblazer for women—remembered by her friends and family.Through her visibility and celebrity, Cokie Roberts was an inspiration and a role model for innumerable women and girls. A fixture on national television and radio for more than 40 years, she also wrote five bestselling books focusing on the role of women in American history. She was portrayed on Saturday Night Live, name checked on the West Wing, and featured on magazine covers. She joked with Jay Leno, balanced a pencil on her nose for David Letterman, and was the answer to numerous crossword puzzle clues. Many dogs, and at least one dairy cow, were named for her. When the legendary 1980s Spy Magazine ran a diagram documenting all her connections with the headline “Cokie Roberts – Moderately Well-Known Broadcast Journalist or Center of the Universe?” they were only half-joking.Cokie had many roles in her lifetime: Daughter. Wife. Mother. Journalist. Advocate. Historian. Reflecting on her life, those closest to her remember her impressive mind, impish wit, infectious laugh, and the tenacity that sent her career skyrocketing through glass ceilings at NPR and ABC. They marvel at how she often put others before herself and cared deeply about the world around her. When faced with daily decisions and dilemmas, many still ask themselves the question, ‘What Would Cokie Do?’In this loving tribute, Cokie’s husband of 53 years and bestselling-coauthor Steve Roberts reflects not only on her many accomplishments, but on how she lived each day with a devotion to helping others. For Steve, Cokie’s private life was as significant and inspirational as her public one. Her commitment to celebrating and supporting other women was evident in everything she did, and her generosity and passion drove her personal and professional endeavors. In Cokie, he has a simple goal: “To tell stories. Some will make you cheer or laugh or cry. And some, I hope, will inspire you to be more like Cokie, to be a good person, to lead a good life.”
Cold Moon Rising: Die Berichterstattung über die erste bemannte Mondlandung als Globalgeschichte in Zeiten des Kalten Krieges
by Sven GramppIn diesem Sammelband wird eine Welt- und Zeitreise in 21 Ländern auf nicht weniger als sechs Kontinente unternommen. So soll die globale Rezeption eines der bis dato größten Medienereignisse Kontur erhalten. Anhand der Berichterstattung über die erste bemannte Mondlandung kann so die Globalgeschichte im/des Kalten Krieges zu Zeiten des Space Racesowohl in ihren vielen unterschiedlichen lokalen Facetten als auch in ihrer weltweiten Vernetzung erzählt werden.Vor dem Hintergrund gegenwärtiger Bestrebungen diverser Länder, wieder auf den Mond zurückzukehren oder gleich eine Weltraumarmee zu gründen, wie auch in Anbetracht der überaus angespannten geopolitischen Lage, die bereits vielerorts als ‚Kalter Krieg 2.0‘ beschworen wird, scheint solch ein weltumspannender Blick zurück in die Zeit des ‚Kalten Krieges 1.0‘ durchaus von Relevanz, um Gegenwart und nahe Zukunft politischer (Medien-)Kulturen besser zu verstehen.
Cold War, Cool Medium: Television, McCarthyism, and American Culture (Film And Culture Ser.)
by Thomas DohertyConventional wisdom holds that television was a co-conspirator in the repressions of Cold War America, that it was a facilitator to the blacklist and handmaiden to McCarthyism. But Thomas Doherty argues that, through the influence of television, America actually became a more open and tolerant place. Although many books have been written about this period, Cold War, Cool Medium is the only one to examine it through the lens of television programming. To the unjaded viewership of Cold War America, the television set was not a harbinger of intellectual degradation and moral decay, but a thrilling new household appliance capable of bringing the wonders of the world directly into the home. The "cool medium" permeated the lives of every American, quickly becoming one of the most powerful cultural forces of the twentieth century. While television has frequently been blamed for spurring the rise of Senator Joseph McCarthy, it was also the national stage upon which America witnessed—and ultimately welcomed—his downfall. In this provocative and nuanced cultural history, Doherty chronicles some of the most fascinating and ideologically charged episodes in television history: the warm-hearted Jewish sitcom The Goldbergs; the subversive threat from I Love Lucy; the sermons of Fulton J. Sheen on Life Is Worth Living; the anticommunist series I Led 3 Lives; the legendary jousts between Edward R. Murrow and Joseph McCarthy on See It Now; and the hypnotic, 188-hour political spectacle that was the Army-McCarthy hearings. By rerunning the programs, freezing the frames, and reading between the lines, Cold War, Cool Medium paints a picture of Cold War America that belies many black-and-white clichés. Doherty not only details how the blacklist operated within the television industry but also how the shows themselves struggled to defy it, arguing that television was preprogrammed to reinforce the very freedoms that McCarthyism attempted to curtail.
Cold War Correspondents: Soviet and American Reporters on the Ideological Frontlines
by Dina FainbergForeign correspondents played a crucial role in promoting the ideas and values of the Cold War. As they brought the foreign world to their Soviet and American readers, these journalists projected their own ideologies onto their reporting.In an age of mutual acrimony and closed borders, journalists were among the few individuals who crossed the Iron Curtain. Their reporting strongly influenced the ways that policy makers, pundits, and ordinary people came to understand the American or the Soviet "other." In Cold War Correspondents, Dina Fainberg examines how Soviet and American journalists covered the rival superpower and how two distinctive sets of truth systems, professional practices, and political cultures shaped international reporting.Fainberg explores private and public interactions among multiple groups that shaped coverage of the Cold War adversary, including journalists and their sources, editors, news media executives, government officials, diplomats, American pundits, Soviet censors, and audiences on both sides. Foreign correspondents, Fainberg argues, were keen analytical observers who aspired to understand their host country and probe its depths. At the same time, they were fundamentally shaped by their cultural and institutional backgrounds—to the point that their views of the rival superpower were refracted through values of their own culture. International reporting grounded and personalized the differences between the two nations, describing the other side in readily recognizable, self-referential terms. Fundamentally, Fainberg demonstrates, Americans and Soviets during the Cold War came to understand themselves through the creation of images of each other. Drawing on interviews with veteran journalists and Soviet dissidents, Cold War Correspondents also uses previously unexamined Soviet and US government records, newspaper and news agency archives, rare Soviet cartoons, and individual correspondents' personal papers, letters, diaries, books, and articles. Striking black-and-white photos depict foreign correspondents in action. Taken together, these sources illuminate a rich history of private and professional lives at the heart of the superpower conflict.
Cold War Games: Propaganda, the Olympics, and U.S. Foreign Policy
by Toby C RiderIt is the early Cold War. The Soviet Union appears to be in irresistible ascendance, and moves to exploit the Olympic Games as a vehicle for promoting international communism. In response, the United States conceives a subtle, far-reaching psychological warfare campaign to blunt the Soviet advance. Drawing on newly declassified materials and archives, Toby C. Rider chronicles how the US government used the Olympics to promote democracy and its own policy aims during the tense early phase of the Cold War. Rider shows how the government, though constrained by traditions against interference in the Games, eluded detection by cooperating with private groups, including secretly funded émigré organizations bent on liberating their home countries from Soviet control. At the same time, the United States appropriated Olympic host cities to hype the American economic and political system while, behind the scenes, the government attempted clandestine manipulation of the International Olympic Committee. Rider also details the campaigns that sent propaganda materials around the globe as the United States mobilized culture in general, and sports in particular, to fight the communist threat.
Cold War Journalism: Between Cold Reception and Common Ground
by Kevin GrievesThis book explores Cold War journalism and journalists as threat, representing ‘enemy’ systems and ideologies. The book also examines Cold War aspirations of forging transnational journalistic connections across the Iron Curtain as well as finding common journalistic ground within the East and West blocs. The book shines a critical light on overly idealistic visions for that journalistic common ground, drawing on primary archival source material to investigate journalists and reporting work, journalistic content and journalistic venues during the Cold War era. This is not a book about traditional war correspondence – rather, it is about the rhetorical battles and the ideological fronts that have shaped and continue to shape our world. By fully understanding how journalism and journalists have intersected with hostile barriers and divisions in the past, we can have a more nuanced understanding of the current global media environment.
Cold War Modernists: Art, Literature, and American Cultural Diplomacy
by Greg BarnhiselCold War Modernists documents how the CIA, the State Department, and private cultural diplomats transformed modernist art and literature into pro-Western propaganda during the first decade of the Cold War
Cold War Photographic Diplomacy: The US Information Agency and Africa
by Darren NewburyThe emergence of newly independent African nations onto the world stage in the mid-twentieth century precipitated a contest for influence among Cold War superpowers, leading the United States to mount an international campaign of photographic diplomacy underpinned by a faith in the medium’s capacity to cross cultural boundaries. However, the increasing global visibility of racial injustice undermined US claims that the nation had transcended colonial racism.Drawing on extensive research in the archives of the United States Information Agency (USIA) and concentrating on the period from the mid-1950s through to the late 1960s, Darren Newbury traces the role of photography in the United States’ appeal to Africa. Newbury shows how photographing the political, cultural, and educational visits of Africans to the United States provided a space for the imagination of international cooperation and friendship; how the United States presented the civil rights struggle as an example of democracy in action; and how it pictured a world of integration and racial coexistence. Cold War Photographic Diplomacy chronicles this careful scripting of images and picture stories and details the cultural and pedagogical work that photography was expected to perform as it was inserted into the visual culture of African cities through magazines, posters, pamphlets, and window displays.Locating photography at the intersection of African decolonization, racial conflict in the United States, and the cultural Cold War, this study will especially appeal to students and scholars of the history of photography, American studies, and Africana studies.

Collaborating with the Enemy: How to Work with People You Don’t Agree with or Like or Trust
by Adam KahaneCollaboration is increasingly difficult and increasingly necessary Often, to get something done that really matters to us, we need to work with people we don't agree with or like or trust. Adam Kahane has faced this challenge many times, working on big issues like democracy and jobs and climate change and on everyday issues in organizations and families. He has learned that our conventional understanding of collaboration—that it requires a harmonious team that agrees on where it's going, how it's going to get there, and who needs to do what—is wrong. Instead, we need a new approach to collaboration that embraces discord, experimentation, and genuine cocreation—which is exactly what Kahane provides in this groundbreaking and timely book.

Collaborations & Innovations: Supporting Multilingual Writers across Campus Units
by Nancy DeJoy Beatrice Quarshie SmithFor decades, U.S. institutions of higher education have discussed ways to meet the needs of multilingual students; the more recent increases in enrollment by international students have created opportunities for productive change across campuses—particularly ways that units can collaborate to better meet those needs. The chapters in this volume demonstrate that teaching effective communication skills to all students in ways that recognize the needs of multiple language users requires a shift in perspective that approaches multilingualism as an opportunity that is enhanced by the internationalization of higher education because it makes transparent the problems of current structures and disciplinary approaches in accessing those opportunities. A goal of this collection is to address the economic, structural, disciplinary, and pedagogical challenges of making this type of shift in bold and compassionate ways. Chapters are organized into these four parts--Program-Level Challenges and Opportunities, Opportunities for Enhancing Teacher Training, Multilingualism and the Revision of First-Year Writing, and Integrating Writing Center Insights—and reflect the perspectives of a variety of university language settings. The contributions feature collaborative models and illustrate the need to rethink structures, pedagogies, assessment/evaluation processes, and teacher training for graduate and undergraduate students who will teach writing and other forms of communication.
Collaborative Information Seeking: The Art and Science of Making the Whole Greater than the Sum of All (The Information Retrieval Series #34)
by Chirag ShahToday's complex, information-intensive problems often require people to work together. Mostly these tasks go far beyond simply searching together; they include information lookup, sharing, synthesis, and decision-making. In addition, they all have an end-goal that is mutually beneficial to all parties involved. Such "collaborative information seeking" (CIS) projects typically last several sessions and the participants all share an intention to contribute and benefit. Not surprisingly, these processes are highly interactive. Shah focuses on two individually well-understood notions: collaboration and information seeking, with the goal of bringing them together to show how it is a natural tendency for humans to work together on complex tasks. The first part of his book introduces the general notions of collaboration and information seeking, as well as related concepts, terminology, and frameworks; and thus provides the reader with a comprehensive treatment of the concepts underlying CIS. The second part of the book details CIS as a standalone domain. A series of frameworks, theories, and models are introduced to provide a conceptual basis for CIS. The final part describes several systems and applications of CIS, along with their broader implications on other fields such as computer-supported cooperative work (CSCW) and human-computer interaction (HCI). With this first comprehensive overview of an exciting new research field, Shah delivers to graduate students and researchers in academia and industry an encompassing description of the technologies involved, state-of-the-art results, and open challenges as well as research opportunities.
