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.

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.

This article aims to investigate the creation of space and sound in artistic and architectural fields, with particular emphasis on the notions of interval and duration in the production and experience of soundscapes. The discussion arises out of an ongoing research project concerning sonic structures in public places, in which Japanese uguisubari ([Formula: see text]) – ‘nightingale flooring’, an alarm system from the Edo period) plays a key role in developing new kinds of site-specific and location-responsive sonic architectural structures for urban and rural environments. This paper takes uguisubari as its frame for investigating and evaluating how sounds create a space (however temporary), and how that sound in turn is created through movement. It thus seeks to unpick aspects of the reciprocal and performative act in which participant and the space engage through movement, whilst creating a sonic environment that permeates, defines and composes the boundaries of this space. The article will develop a framework for these kinds of works through a discussion on walking, movement, soundscape and somatechnical aspects of our experience of the world, drawing upon the work of Merleau-Ponty, Bergson and the Japanese concept of Ma (space-time).
