论文摘要
人类社会包括各种社会关系。朋友，家人，商业同事和在线联系都可以为一个人的社交生活做出贡献。个人在不同领域的行为可能会有所不同，但是一个领域的成功可能会在另一个领域取得成功。在这里，我们使用多层网络研究了这个问题，以模拟社交互动的多个领域，在这种互动中，个人会经历不同的环境并可能表达不同的行为。我们提供了数学分析，发现层之间的耦合倾向于促进亲社会行为。即使仅在每个层中都不利于亲社会性，多层耦合也可以同时促进其在所有层中的增殖。我们将此分析应用于六个现实世界中的多层网络，从赞比亚社区的社会情感和专业关系到学术大学内的在线和离线关系。我们讨论了结果的含义，这表明对一个域中的相互作用进行了少量修改可能会催化不同领域中的亲社会性。
Human societies include diverse social relationships. Friends, family, business colleagues, and online contacts can all contribute to one's social life. Individuals may behave differently in different domains, but success in one domain may engender success in another. Here, we study this problem using multilayer networks to model multiple domains of social interactions, in which individuals experience different environments and may express different behaviors. We provide a mathematical analysis and find that coupling between layers tends to promote prosocial behavior. Even if prosociality is disfavored in each layer alone, multilayer coupling can promote its proliferation in all layers simultaneously. We apply this analysis to six real-world multilayer networks, ranging from the socio-emotional and professional relationships in a Zambian community, to the online and offline relationships within an academic University. We discuss the implications of our results, which suggest that small modifications to interactions in one domain may catalyze prosociality in a different domain.
