By adopting the uses and gratifications approach to understand two evolutionary needs—the environmental surveillance need and social involvement need—this study investigated the use of alarm and prosocial words in news headlines and the associated generic digital footprints. We analyzed over 170,000 online news headlines and the number of associated clicks and “likes” for each news story on an online news platform. Our results support the idea of a human alarm system for sensational news as a psychological survival mechanism designed to detect and pay attention to threatening news such as catastrophes and diseases. News headlines with alarm words indirectly attracted more “likes,” indicating a concern with survival, through an increased number of clicks to select that news item. Furthermore, the results of a conditional indirect effect model showed that while online readers selectively clicked on news headlines with alarm words, the presence of a prosocial word in the headline increased the likelihood that readers would “like” it.

Effect Model

Recently in U.S. and Europe, the approach for the safety of plant intensifies because of many accidents in plant. In the　approaches, alarm system is especially important. Alarms should be used to enable operators to diagnose faults of plant and plan countermeasures. To accomplish these functions, nuisance alarms should be eliminated. In this study, we suggest a systematic method of alarm system design for unsteady state process by using Cause-Effect model. The presumed indicators were chosen from intended indicators are theoretically guaranteed to be able to qualitatively distinguish all assumed faults. And by use of the different model for each process in unsteady state operation, it is considered that fault candidates and indicators are restricted. The method is applied to a simple process for the case study.
