Individuals derive their identities from their social networks. By forging dynamic connections, people accomplish innumerable worthwhile activities, such as giving to charity and sharing knowledge. Unfortunately, social networks also can bring great harm to their members. Panics may reverberate across financial networks, quickly sending stock markets into death spirals and shutting down credit for businesses and consumers. Pathogens like the AIDS virus can sweep across sexual and other networks. In this book, acclaimed scientists and academics Nicholas A. Christakis and James H. Fowler explore the properties and capacities of social networks. They present their findings about how and why people connect. getAbstract recommends their analysis to sociology and psychology buffs, as well as to managers and marketers who would like to develop more insight into how to take advantage of social networks.
