"Katherine Giuffre reveals the deep underlying relational commonalities of such diverse contexts as small town life at the end of Weimar, the Salem witch-frenzy, Boston's East End, and the rise of Apple in Silicon Valley with richly textured description carried by elegantly clear prose that makes reading Communities and Networks both incredibly informative and delightful."—Peter Bearman, Columbia University"If you are looking for a compelling introduction to basic concepts and methods of social network modeling that will expand your imagination and help you become a more astute analyst of society and culture, then this is the book for you. Katherine Giuffre writes with insight and verve."—Ronald Breiger, University of Arizona"Forty years ago, people thought of community as a neighborhood. Now social networks have busted the boundaries of communities. They are far-flung and much more than village-like solidarities. The Internet and Mobile Revolutions have pushed these processes even further: community is now in our pocket and on our screens. Communities have become networks; networks have become communities. Katherine Giuffre tells this story well, and supplies solid evidence to clinch the tale."—Barry Wellman, University of Toronto"Giuffre's Communities and Networks is one of the clearest and most engaging introductions to adopting a network perspective on urban and community issues and, by covering a wide range of substantive topics, will be of great interest to a broad audience of students." (Urban Studies, 2016)"Throughout the book, Giuffre attempts to explain the importance of social network analysis by using case studies from diverse communities (where abortion was legal, activism in local neighborhoods, and the ever-popular Silicon Valley) and by ending some chapters with technical details on how to gather and analyze real data. Her chapters are dedicated to broad but important questions." (Information, Communication & Society)
