摘要

冰桶挑战是一项旨在鼓励向肌萎缩侧索硬化症协会捐款的社交游戏。这些规则意味着，每个参与者向每个被招募的追随者挑战，让他们把一桶冰水倒在自己的头上。谁提名谁的网络呈树形结构。冰桶挑战的持续时间很短，在假设参与者招募追随者的能力不同的情况下，可以用复制数来解释。该流行病持续到传播树的中断，在易感追随者耗尽之前发生。这样的树是根据公开可用的联系数据和对游戏的兴趣重建的。

Termination of the ice bucket challenge

ABSTRACT The ice bucket challenge is a social game aimed at encouraging donations to the amyotrophic lateral sclerosis association. The rules imply that each participant challenges each recruited follower to dump a bucket of ice water on his or her head. The network of who has nominated whom has a tree structure. The short duration of the ice bucket challenge is explained by using the reproduction number , under the assumption that the capacity to recruit followers varies with the participant. The epidemic lasts until the interruption of the transmission tree occurring well before the depletion of susceptible followers. Such a tree is reconstructed from publicly available contact data and the interest in this game.

期刊介绍： Mathematical Population Studies publishes carefully selected research papers in the mathematical and statistical study of populations. The journal is strongly interdisciplinary and invites contributions by mathematicians, demographers, (bio)statisticians, sociologists, economists, biologists, epidemiologists, actuaries, geographers, and others who are interested in the mathematical formulation of population-related questions. The scope covers both theoretical and empirical work. Manuscripts should be sent to Manuscript central for review. The editor-in-chief has final say on the suitability for publication.
