With funding from the National Natural Science Foundation of China (approval numbers: 72042009, 72074072), etc.
, Professor Jia Jianmin (corresponding author) of the Chinese University of Hong Kong (Shenzhen) and overseas collaborators revealed people’s communication behaviors in emergency situations through mobile big data, and proposed The ternary embedded structure of the network is used to study the dynamic evolution mechanism of family and social networks
Many difficult-to-observe attributes of complex social systems can only be revealed under special circumstances
.
This research is based on the individual mobile communication data of the victims in the 2013 Ya'an earthquake, using the earthquake as a natural experiment to study people's emergency communication behaviors and response behaviors in risky environments, revealing the micro-mechanism of social networks-embeddedness An important role, the Triadic embeddedness structure is proposed to analyze in depth how the various embeddedness structures of the three-person family affect people’s emergency communication behaviors after the earthquake
The study used a similar double-differential analysis method and found that under higher earthquake intensity, those families with a complete embedded structure would contact their family members in a shorter time (Figure 1), and their intra-family communication also showed more Interaction, and there will be more communication between them and social network members outside the nuclear family
.
In addition, family members with more embedded networks also have greater network centrality, which indicates that family relationships and friend relationships are complementary rather than substitutes.
