网络、群体与市场
过去十年来,现代社会中复杂的连通性向公众展现出与日俱增的魅力。这种连通性在许多方面都有体现并发挥着强大的作用,包括互联网的快速成长、全球通信的便捷,以及新闻与信息(及传染病与金融危机)以惊人的速度与强度传播的能力。这种现象涉及网络、动机和人们的聚合行为。网络将人们的行为联系起来,使得每个人的决定可能对他人产生微妙的后果。 本书是本科生的入门教材,同时也适合希望进入相关领域的高层次读者。它从交叉学科的角度出发,综合运用经济学、社会学、计算与信息科学以及应用数学的有关概念与方法,考察网络行为原理及其效应机制。以深入浅出的方式描述了在网络的作用下正在浮现与发展起来的一些交叉学科领域,讨论了社会、经济和技术领域相互联系的若干基本问题。本书是一本带你跨入信息科学和社会科学交叉领域研究之门的优秀参考书。 -
Networks, Crowds, and Markets
Are all film stars linked to Kevin Bacon? Why do the stock markets rise and fall sharply on the strength of a vague rumour? How does gossip spread so quickly? Are we all related through six degrees of separation? There is a growing awareness of the complex networks that pervade modern society. We see them in the rapid growth of the Internet, the ease of global communication, the swift spread of news and information, and in the way epidemics and financial crises develop with startling speed and intensity. This introductory book on the new science of networks takes an interdisciplinary approach, using economics, sociology, computing, information science and applied mathematics to address fundamental questions about the links that connect us, and the ways that our decisions can have consequences for others. -
Social Network Analysis
Social network analysis is used widely in the social and behavioral sciences, as well as in economics, marketing, and industrial engineering. The social network perspective focuses on relationships among social entities and is an important addition to standard social and behavioral research, which is primarily concerned with attributes of the social units. Social Network Analysis: Methods and Applications reviews and discusses methods for the analysis of social networks with a focus on applications of these methods to many substantive examples. It is a reference book that can be used by those who want a comprehensive review of network methods, or by researchers who have gathered network data and want to find the most appropriate method by which to analyze it. It is also intended for use as a textbook as it is the first book to provide comprehensive coverage of the methodology and applications of the field.
