Disasters can move quickly. Effective communication is a critical resource that can significantly enhance public safety. A mass notification system (MNS) uses text messaging to inform constituents of crisis, provide recommendations, connect to resources, and has the advantage of speed. Limited research has been conducted on the variables that influence the effectiveness, utilization, and perceptions of MNS. The extant study employs a multi-method approach to advance the scholarly knowledge on MNS. All emergency managers in a state were surveyed on issues of MNS enrollment, utilization, and brand. A subgroup of emergency managers were then interviewed to provide depth to the survey findings. Key findings indicate wide variability in MNS usage, little relationship between population size and enrollment, and a high perceived importance of MNS as a communication modality. Policy implications and recommendations are offered.

应急管理人员对群众通报系统有效性和局限性的认识：混合方法研究

灾难可能会迅速蔓延。有效的沟通是可以显着提高公共安全的重要资源。批量通知系统（MNS）使用文本消息通知危机的组成部分，提供建议，连接到资源并具有速度优势。对影响MNS的有效性，利用率和感知度的变量进行了有限的研究。现有的研究采用多方法的方法来提高有关MNS的学术知识。对该州的所有紧急管理人员进行了有关MNS的注册，使用和品牌问题的调查。然后，采访了一组应急管理人员，以深入了解调查结果。主要发现表明，MNS使用情况的差异很大，人口规模与入学率之间的关系不大，以及MNS作为一种通讯方式的高度重视。提供了政策含义和建议。
