Unsafe acts are a primary cause of maritime accidents, but timely reminders can evaluate improper behavior and provide alerts to prompt correction. This paper investigates whether timely reminders can discourage unsafe acts. First, data in relation to participants’ unsafe acts according to different psychological frames were collected on the basis of an experiment conducted on a navigation simulator. The effects of timely reminders on unsafe acts were then analyzed through the independent-samples Kruskal–Wallis test and regression analysis. The results demonstrate that the introduction of timely reminders could significantly reduce the number of unsafe acts committed by crew members during voyages. Moreover, the framing effect influenced the intervention results; under less stressful conditions, a timely reminder with the gain frame more effectively discourages unsafe acts than does a reminder with the loss frame. By contrast, under more stressful conditions, the loss frame exhibits advantages over the gain frame with respect to sending timely reminders to reduce the occurrence of unsafe acts. Compared with novices, experienced seafarers are less sensitive to the effects of timely reminders in the process of ship operation, whether with the gain frame or loss frame. After the three major challenges of functional subdivision, situational complexity, and mechanism robustness are discussed, two suggestions are proposed: an integrated system for automatically detecting unsafe acts that sends out corresponding timely reminders and an onboard organizational management mechanism.

探索及时提醒对海上不安全行为的影响

不安全行为是造成海事事故的主要原因,但是及时提醒可以评估不当行为并提供警报以进行及时纠正。本文研究了及时提醒是否可以阻止不安全行为。首先,根据在导航模拟器上进行的实验,收集了与参与者根据不同心理框架的不安全行为有关的数据。然后通过独立样本Kruskal–Wallis检验和回归分析来分析及时提醒对不安全行为的影响。结果表明,及时提醒的引入可以大大减少乘员在航行中所犯下的不安全行为。而且,成帧效果影响了干预效果。在压力较小的情况下,与具有损失框架的提醒相比,及时地利用收益框架进行提醒可以更有效地阻止不安全行为。相比之下,在压力更大的情况下,就及时发送提醒以减少不安全行为的发生而言,损失帧比收益帧更具优势。与新手相比,经验丰富的海员对船舶运营过程中及时提醒的影响不那么敏感,无论是收益框架还是损失框架。在讨论了功能细分,情况复杂性和机制稳健性这三个主要挑战之后,提出了两个建议:一个用于自动检测不安全行为并发出相应及时提醒的集成系统,以及一个机载组织管理机制。相比之下,在压力更大的情况下,就及时发送提醒以减少不安全行为的发生而言,损失帧比收益帧更具优势。与新手相比,经验丰富的海员对船舶运营过程中及时提醒的影响不那么敏感,无论是收益框架还是损失框架。在讨论了功能细分,情况复杂性和机制稳健性这三个主要挑战之后,提出了两个建议:一个用于自动检测不安全行为并发出相应及时提醒的集成系统,以及一个机载组织管理机制。相比之下,在压力更大的情况下,就及时发送提醒以减少不安全行为的发生而言,损失帧比收益帧更具优势。与新手相比,经验丰富的海员对船舶运营过程中及时提醒的影响不那么敏感,无论是收益框架还是损失框架。在讨论了功能细分,情况复杂性和机制稳健性这三个主要挑战之后,提出了两个建议:一个用于自动检测不安全行为并发出相应及时提醒的集成系统,以及一个机载组织管理机制。与新手相比,经验丰富的海员对船舶运营过程中及时提醒的影响不那么敏感,无论是收益框架还是损失框架。在讨论了功能细分,情况复杂性和机制稳健性这三个主要挑战之后,提出了两个建议:一个用于自动检测不安全行为并发出相应及时提醒的集成系统,以及一个机载组织管理机制。与新手相比,经验丰富的海员对船舶运营过程中及时提醒的影响不那么敏感,无论是收益框架还是损失框架。在讨论了功能细分,情况复杂性和机制稳健性这三个主要挑战之后,提出了两个建议:一个用于自动检测不安全行为并发出相应及时提醒的集成系统,以及一个机载组织管理机制。
