The Age of Sharing
22,62 € *
ggf. zzgl. Versand

Sharing is central to how we live today: it is what we do online; it is a model of economic behaviour; and it is also a type of therapeutic talk. Sharing embodies positive values such as empathy, communication, fairness, openness and equality. The Age of Sharing shows how and when sharing became caring, and explains how its meanings have changed in the digital age. But the word ?sharing? also camouflages commercial or even exploitative relations. Websites say they share data with advertisers, although in reality they sell it, while parts of the sharing economy look a great deal like rental services. Ultimately, it is argued, practices described as sharing and critiques of those practices have common roots. Consequently, the metaphor of sharing now constructs significant swathes of our social practices and provides the grounds for critiquing them; it is a mode of participation in the capitalist order as well as a way of resisting it. Drawing on nineteenth-century literature, Alcoholics Anonymous, the American counterculture, reality TV, hackers, Airbnb, Facebook and more, The Age of Sharing offers a rich account of a complex contemporary keyword. It will appeal to students and scholars of the internet, digital culture and linguistics. Nicholas John is Assistant Professor at The Hebrew University of Jerusalem.

Market-Driven Spectrum Sharing in Cognitive Radio
55,92 € *
ggf. zzgl. Versand

This brief focuses on the current research on mechanism design for dynamic spectrum sharing in cognitive radio (CR) networks. Along with a review of CR architectures and characteristics, this brief presents the motivations, significances and unique challenges of implementing algorithmic mechanism design for encouraging both primary spectrum owners and secondary spectrum users to participate in dynamic spectrum sharing. The brief then focuses on recent advances in mechanism design in CR networks. With an emphasis on dealing with the uncertain spectrum availabilities, mechanisms based on spectrum recall, two-stage spectrum sharing and online spectrum allocation are introduced with the support of theoretic analyses and numerical illustrations. The brief concludes with a discussion of potential research directions and interests, which will motivate further studies on mechanism design for wireless communications. This brief is concise and approachable for researchers, professionals and advanced-level students in wireless communications and networks.

Economics of Database-Assisted Spectrum Sharing
83,29 € *
ggf. zzgl. Versand

This book examines the interaction between the technical and economic issues in database-assisted dynamic spectrum networks. It explains various business models for different network settings, analyzing the user behaviors and system equilibrium under each model. With the explosive growth of mobile devices and bandwidth-hungry applications, radio spectrum is becoming increasingly congested and scarce. Database-assisted dynamic spectrum sharing is a promising technology for solving the problem of spectrum scarcity and congestion by allowing unlicensed mobile devices to dynamically access the under-utilized licensed spectrum resources through the assistance of a database. Database-assisted spectrum sharing network architecture has received wide and enthusiastic support from spectrum regulators, standards bodies, and industrial organizations. This book serves as a resource for researchers in white space communications and networking, for regulators in the wireless industry, and for graduate students and senior undergraduate students taking a course on network economics.

Sharing Turf is the uplifting, true-life story of a community torn by racial strife, and ultimately coming together to make things better. Just weeks after race riots threatened to further divide Blacks & Hassidic Jews in Crown Heights, Brooklyn, a few youth leaders came together to see if there was anything they could do to foster peace & mutual respect in their community. Initially, youth from both sides came together to dialogue with each other. The participants themselves wanted to carry on and continue with these important discussions. These meetings eventually led to playing sports together, painting art murals in the community, and even making music together. Despite the odds, both on an individual level and from society at large, they formed Project CURE, which stands for Communication, Understanding, Respect, & Education. What they accomplished is nothing short of remarkable, from playing ball during halftime at several NY Knicks games to the CURE band opening up for the US Congress. This feel-good story resonates in todays complex world more than ever, showing what a few caring individuals can do to change society for the better. Starting with just a few youth leaders in the Crown Heights section of Brooklyn, the effort of Project CURE What started as a grassroots level eventually grew into .
