Mobile emergency warning apps are essential for effective emergency communication – of course, provided the population intends to use them. Drawing on protection motivation theory, the study validated a psychometric model to explain what motivates individuals to install a warning app for the first time and to keep using it over time.

SMS warnings are critical to alert campus communities in case of emergency. But how effective are they in enabling users' compliance with a warning? Our survey of a student sample shows a major flaw in the design of SMS warnings: they fail to provide their recipients with adequate spatial awareness; that, in turn, hinders their ability to counterac...

Effective emergency communication is crucial, as it increases a population’s attentiveness and ability to respond to emergencies in a timely manner. However, authorities have sometimes struggled with using emergency warning systems (EWS) effectively, leading to warnings that are late, inaccurate, or sometimes are never issued at all. This research...

Emergency warning apps are critical to alert the population during emergencies, but are countries using them effectively? There is little theoretical understanding of what it means to use warning apps effectively. As a result, there is also little knowledge about how to design them.

Effective warning can be life-saving in the event of an emergency. The pervasiveness of smartphones among the population affords public authorities a distributed network they can leverage for emergency notification. In Germany, for instance, warning apps (e.g., NINA, Katwarn) are integrated within emergency warning systems (EWS) authorities use for...

Recent terrorist attacks have increased the need to examine the public's response to such threats. This study focuses on the content of Twitter messages related to the 2016 terrorist attack on the Berlin Christmas market. We complement the collective sense-making perspective with the terror management theory (TMT) perspective to understand why peop...

Modeling, analysis, control, and management of complex social networks represent an important area of interdisciplinary research in an advanced digitalized world. In the last decade social networks have produced significant online applications which are running on top of a modern Internet infrastructure and have been identified as major driver of t...

In the wake of an increasing interest in the communication networks of emergency responders, radio communication systems have been recognized as an important source of digital trace data. In this paper, we explore how radio data can be used as part of social network analysis (SNA). In particular, we investigate how social networks can be modeled an...
