论文摘要
烟草产品的调节正在迅速发展。理解公众对变化的情绪非常重要，因为当局评估了如何有效保护人口健康。社交媒体系统被广泛认为可用于收集有关人类偏好和看法的数据。但是，在快速的政策变更设置中，如何使用社交媒体数据，考虑到狭窄的时间段和特定位置的挑战以及非代表性的人口使用社交媒体是一个悬而未决的问题。在本文中，我们采用了以前在社交媒体等观测数据中使用的准实验设计，以控制社交媒体上的时间和位置混杂因素，然后使用Twitter和Reddit帖子的内容分析来说明烟草风味禁令的反应内容以及税收对电子烟的影响。结论将社交媒体在迅速变化的监管环境中的潜在作用提炼，以补充传统基于传统的代表性调查所学的内容。
Regulation of tobacco products is rapidly evolving. Understanding public sentiment in response to changes is very important as authorities assess how to effectively protect population health. Social media systems are widely recognized to be useful for collecting data about human preferences and perceptions. However, how social media data may be used, in rapid policy change settings, given challenges of narrow time periods and specific locations and non-representative the population using social media is an open question. In this paper we apply quasi-experimental designs, which have been used previously in observational data such as social media, to control for time and location confounders on social media, and then use content analysis of Twitter and Reddit posts to illustrate the content of reactions to tobacco flavor bans and the effect of taxation on e-cigarettes. Conclusions distill the potential role of social media in settings of rapidly changing regulation, in complement to what is learned by traditional denominator-based representative surveys.
