论文摘要
在这项工作中，我们研究了一个简单的饮酒行为演化室模型。人口分为3个隔间，分别是他们的饮酒，即易感人$ s $（非消费者），中度饮酒者$ m $和风险饮用者$ r $。这些州之间的过渡是由概率统治的。尽管模型很简单，但我们观察到了两种不同的非平衡相转变以吸收状态。这些状态之一仅由易感个人$ s $组成，没有饮酒者（$ m = r = 0 $）。另一方面，另一个吸收状态仅由风险饮用者$ r $（$ s = m = 0 $）组成。在这两个稳态之间，我们具有三个亚群$ S $，$ M $和$ r $的共存。与巴西的滥用酒精消耗数据的比较显示了模型的结果与数据库之间的良好一致性。
In this work we study a simple compartmental model for drinking behavior evolution. The population is divided in 3 compartments regarding their alcohol consumption, namely Susceptible individuals $S$ (nonconsumers), Moderate drinkers $M$ and Risk drinkers $R$. The transitions among those states are ruled by probabilities. Despite the simplicity of the model, we observed the occurrence of two distinct nonequilibrium phase transitions to absorbing states. One of these states is composed only by Susceptible individuals $S$, with no drinkers ($M=R=0$). On the other hand, the other absorbing state is composed only by Risk drinkers $R$ ($S=M=0$). Between these two steady states, we have the coexistence of the three subpopulations $S$, $M$ and $R$. Comparison with abusive alcohol consumption data for Brazil shows a good agreement between the model's results and the database.
