本研究探讨了酒类许可证政策的巨大变化对大都市地区酒类零售业的影响。该政策的颁布是为了取消固定的关闭时间，并在可能减少暴力犯罪和混乱的地区设置交错的关闭时间。我们发现很大的变化在何种程度上的政策的规定被安装为intention.Policy ImplicationsThe研究结果表明，事先考虑如何将政策干预措施应用于现实世界的设置是很重要的研究评估的有效性。了解和监测干预措施实施过程中的变化是评价结果的重要先决条件。如果不了解干预措施在现实世界中的应用，研究人员就有可能将因果效应归因于可能不存在或仅部分收到的预防措施。
This study examines the effects of a dramatic change in alcohol licensing policy on the practice of liquor retailing across a metropolitan urban region. The policy was enacted to remove fixed closing times and to install staggered closing times across regions where it potentially would reduce violent crime and disorder. We found great variation in the extent to which the provisions of the policies were installed as intended.Policy ImplicationsThe findings suggest that prior consideration for how policy interventions will be applied to real-world settings is important to the validity of research evaluations. Understanding and monitoring variation in the implementation of an intervention is a vital prerequisite to the evaluation of outcomes. Without knowledge of the real-world application of an intervention, researchers risk attributing causal effects to a prevention initiative that might have been absent or only partially received.
