Networks pervade social and economic life, and they play a prominent role in explaining a huge variety of social and economic phenomena. Standard economic theory did not give much credit to the role ...of networks until the early 1990s, but since then the study of the theory of networks has blossomed. At the heart of this research is the idea that the pattern of connections between individual rational agents shapes their actions and determines their rewards. The importance of connections has in turn motivated the study of the very processes by which networks are formed.
This book studies the rise of social media in the first decade of the twenty-first century, up until 2012. It provides both a historical and a critical analysis of the emergence of networking ...services in the context of a changing ecosystem of connective media. Such history is needed to understand how the intricate constellation of platforms profoundly affects our experience of online sociality. In a short period of time, services like Facebook, YouTube and many others have come to deeply penetrate our daily habits of communication and creative production. While most sites started out as amateur-driven community platforms, half a decade later they have turned into large corporations that do not just facilitate user connectedness, but have become global information and data mining companies extracting and exploiting user connectivity. Offering a dual analytical prism to examine techno-cultural as well as socio-economic aspects of social media, the author dissects five major platforms: Facebook, Twitter, Flickr, YouTube, and Wikipedia. Each of these microsystems occupies a distinct position in the larger ecosystem of connective media, and yet, their underlying mechanisms for coding interfaces, steering users, filtering content, governance and business models rely on shared ideological principles. Reconstructing the premises on which these platforms are built, this study highlights how norms for online interaction and communication gradually changed. “Sharing,” “friending,” “liking,” “following,” “trending,” and “favoriting” have come to denote online practices imbued with specific technological and economic meanings. This process of normalization is part of a larger political and ideological battle over information control in an online world where everything is bound to become “social.”

Daily life is connected life, its rhythms driven by endless email pings and responses, the chimes and beeps of continually arriving text messages, tweets and retweets, Facebook updates, pictures and ...videos to post and discuss. Our perpetual connectedness gives us endless opportunities to be part of the give-and-take of networking. Some worry that this new environment makes us isolated and lonely. But in Networked , Lee Rainie and Barry Wellman show how the large, loosely knit social circles of networked individuals expand opportunities for learning, problem solving, decision making, and personal interaction. The new social operating system of "networked individualism" liberates us from the restrictions of tightly knit groups; it also requires us to develop networking skills and strategies, work on maintaining ties, and balance multiple overlapping networks. Rainie and Wellman outline the "triple revolution" that has brought on this transformation: the rise of social networking, the capacity of the Internet to empower individuals, and the always-on connectivity of mobile devices. Drawing on extensive evidence, they examine how the move to networked individualism has expanded personal relationships beyond households and neighborhoods; transformed work into less hierarchical, more team-driven enterprises; encouraged individuals to create and share content; and changed the way people obtain information. Rainie and Wellman guide us through the challenges and opportunities of living in the evolving world of networked individuals.
An eye-opening look at the invisible workers who protect us from seeing humanity's worst on today's commercial internetSocial media on the internet can be a nightmarish place. A primary shield ...against hateful language, violent videos, and online cruelty uploaded by users is not an algorithm. It is people. Mostly invisible by design, more than 100,000 commercial content moderators evaluate posts on mainstream social media platforms: enforcing internal policies, training artificial intelligence systems, and actively screening and removing offensive material-sometimes thousands of items per day. Sarah T. Roberts, an award-winning social media scholar, offers the first extensive ethnographic study of the commercial content moderation industry. Based on interviews with workers from Silicon Valley to the Philippines, at boutique firms and at major social media companies, she contextualizes this hidden industry and examines the emotional toll it takes on its workers. This revealing investigation of the people "behind the screen" offers insights into not only the reality of our commercial internet but the future of globalized labor in the digital age.
For decades, a new type of terrorism has been quietly gathering ranks in the world. America's ability to remain oblivious to these new movements ended on September 11, 2001. The Islamist fanatics in ...the global Salafi jihad (the violent, revivalist social movement of which al Qaeda is a part) target the West, but their operations mercilessly slaughter thousands of people of all races and religions throughout the world. Marc Sageman challenges conventional wisdom about terrorism, observing that the key to mounting an effective defense against future attacks is a thorough understanding of the networks that allow these new terrorists to proliferate. Based on intensive study of biographical data on 172 participants in the jihad,Understanding Terror Networksgives us the first social explanation of the global wave of activity. Sageman traces its roots in Egypt, gestation in Afghanistan during the Soviet-Afghan war, exile in the Sudan, and growth of branches worldwide, including detailed accounts of life within the Hamburg and Montreal cells that planned attacks on the United States. U.S. government strategies to combat the jihad are based on the traditional reasons an individual was thought to turn to terrorism: poverty, trauma, madness, and ignorance. Sageman refutes all these notions, showing that, for the vast majority of the mujahedin, social bonds predated ideological commitment, and it was these social networks that inspired alienated young Muslims to join the jihad. These men, isolated from the rest of society, were transformed into fanatics yearning for martyrdom and eager to kill. The tight bonds of family and friendship, paradoxically enhanced by the tenuous links between the cell groups (making it difficult for authorities to trace connections), contributed to the jihad movement's flexibility and longevity. And although Sageman's systematic analysis highlights the crucial role the networks played in the terrorists' success, he states unequivocally that the level of commitment and choice to embrace violence were entirely their own.Understanding Terror Networkscombines Sageman's scrutiny of sources, personal acquaintance with Islamic fundamentalists, deep appreciation of history, and effective application of network theory, modeling, and forensic psychology. Sageman's unique research allows him to go beyond available academic studies, which are light on facts, and journalistic narratives, which are devoid of theory. The result is a profound contribution to our understanding of the perpetrators of 9/11 that has practical implications for the war on terror.
How the Other Half Workssolves the riddle of America's contemporary immigration puzzle: why an increasingly high-tech society has use for so many immigrants who lack the basic skills that today's ...economy seems to demand. In clear and engaging style, Waldinger and Lichter isolate the key factors that explain the presence of unskilled immigrants in our midst. Focusing on Los Angeles, the capital of today's immigrant America, this hard-hitting book elucidates the other side of the new economy, showing that hiring is finding not so much "one's own kind" but rather the "right kind" to fit the demeaning, but indispensable, jobs many American workers disdain.

From the Internet to networks of friendship, disease transmission, and even terrorism, the concept--and the reality--of networks has come to pervade modern society. But what exactly is a network? ...What different types of networks are there? Why are they interesting, and what can they tell us? In recent years, scientists from a range of fields--including mathematics, physics, computer science, sociology, and biology--have been pursuing these questions and building a new "science of networks." This book brings together for the first time a set of seminal articles representing research from across these disciplines. It is an ideal sourcebook for the key research in this fast-growing field.
Success in criminal enterprise largely depends on how offenders go about committing their crimes. An offender?s search for increasing financial returns and decreasing costs is mediated by the ...structure of his pool of useful and trustworthy contacts. InContacts, Opportunities, and Criminal Enterprise, Carlo Morselli examines how business-oriented criminals who have personal networks designed to promote high numbers of diverse contacts achieve and maintain competitive advantages in their earning activities and overall criminal careers.
Based on two case studies of criminal careers in international cannabis smuggling and Cosa Nosta racketeering, the book proposes a social network framework to study the underlying social relationships influencing achievement in crime. Morselli further utilizes this relational approach to illustrate how survival and long-term endurance in criminal enterprise is achieved, and how criminals? networks of contacts and opportunities can insulate them from potentially career-damaging forces ? law enforcement, fellow criminals, etc.Contacts, Opportunities, and Criminal Enterpriseis a much-needed assessment of criminal activity.
This important new book is a comparative study of social mobility based on qualitative interviews with middle-class parents in America and Britain. It addresses the key issue in stratification ...research, namely, the stability of class relations and middle-class reproduction. Drawing on interviewee accounts of how parents mobilised economic, cultural and social resources to help them into professional careers, it then considers how the interviewees, as parents, seek to increase their children's chances of educational success and occupational advancement. Middle-class parents may try to secure their children's social position but it is not an easy or straightforward affair. With the decline of the quality of state education and increased job insecurity in the labour market since the 1970s and 1980s, the reproduction of advantage is more difficult than in the affluent decades of the 1950s and 1960s. The implications for public policy, especially public investment in higher education, are considered.
