年轻人生活在比老年人更小的世界里吗？人际交往中的特殊分离度
Do the Young Live in a "Smaller World" Than the Old? Age-Specific Degrees of Separation in Human Communication
摘要：
在本文中，我们调查的现象“特定年龄的小世界”使用的数据从一个大规模的移动通信网络近似的互动模式在社会规模。我们不是问两个随机个体是否被少量的链接分开，而是问特定年龄组的个体是否生活在一个与其他年龄组的个体相关的小世界中。我们的分析表明，有系统的变化，这种年龄相对的小世界效应。年轻人生活在“最小的世界”中，与其他年轻人和他们的父母一代分开，中间人的数量少于老年人。最年长的人生活在“最小的世界”中，通过大量中介将他们与同龄人和年轻人分开。小世界效应的变化特定于作为节点属性的年龄（在性别的情况下不存在），并且在几个数据稳健性检查下始终观察到。特定年龄的小世界的发现与众所周知的社会机制是一致的，这些机制影响年龄与网络连接的相互作用方式，以及在这个网络中观察到的亲属关系和非亲属关系的相对普遍性。这种社会模式对我们理解信息级联、扩散现象以及时尚和流行的传播的世代特定动态具有重要意义。
英文摘要：
In this paper, we investigate the phenomenon of "age-specific small worlds" using data from a large-scale mobile communication network approximating interaction patterns at societal scale. Rather than asking whether two random individuals are separated by a small number of links, we ask whether individuals in specific age groups live in a small world in relation to individuals from other age groups. Our analysis shows that there is systematic variation in this age-relative small world effect. Young people live in the "smallest world," being separated from other young people and their parent's generation via a smaller number of intermediaries than older individuals. The oldest people live in the "least small world," being separated from their same age peers and their younger counterparts by a larger number of intermediaries. Variation in the small world effect is specific to age as a node attribute (being absent in the case of gender) and is consistently observed under several data robustness checks. The discovery of age-specific small worlds is consistent with well-known social mechanisms affecting the way age interacts with network connectivity and the relative prevalence of kin ties and non-kin ties observed in this network. This social pattern has significant implications for our understanding of generation-specific dynamics of information cascades, diffusion phenomena, and the spread of fads and fashions.
