突发事件中旁观者干预的救援模式
Rescue Model for the Bystanders' Intervention in Emergencies
摘要：
为了研究社会互动对旁观者在紧急情况下的干预的影响，我们引入了一个救援模型，其中包括受害者的熟人与旁观者和旁观者之间的影响。该模型再现了令人惊讶的实验结果，即虽然旁观者$k$的数量增加，但帮助率趋于下降。该模型还表明，考虑到旁观者之间的耦合效应，当$k$在一定范围内较小时，救助率随$k$的增大而增大，耦合效应在突发事件中既有积极作用，也有消极作用。最后，我们找到了一个广泛的耦合强度，以最大限度地提高帮助率。
英文摘要：
To investigate an effect of social interaction on the bystanders' intervention in emergency situations we introduce a rescue model which includes the effects of the victim's acquaintance with bystanders and those among bystanders. This model reproduces the surprising experimental result that the helping rate tends to decrease although the number of bystanders $k$ increases. The model also shows that given the coupling effect among bystanders, for a certain range of small $k$ the helping rate increases according to $k$ and that coupling effect plays both positive and negative roles in emergencies. Finally we find a broad range of coupling strength to maximize the helping rate.
