    A Protection-Motivation Perspective to Explain Intention to Use and Continue to Use Mobile Warning Systems
    (Business & Information Systems Engineering: Vol. 64, No. 2, 2022) Fischer-Preßler, Diana; Bonaretti, Dario; Fischbach, Kai
    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. Multi-group covariance-based structural equation modeling was used to model the answers to a survey that measured the drivers of intention to begin using or intention to continue using a warning app. The model shows that, for both non-users and users, trust, social influence, and response efficacy positively and maladaptive rewards negatively affect intention to use and intention to continue use warning apps. However, perceived vulnerability influences only intention to use, whereas response cost and self-efficacy affect continued use intention. Hence, this study enhances the theoretical understanding of technology-enabled protection behaviors and provides practitioners with a list of factors to consider for pushing the adoption and continued use of emergency warning applications.

    Evolution of Disaster Spatial Risk Assessments: a Bibliometric Analysis
    (EnviroInfo 2022, 2022) Wong, Ingrid; Greve, Klaus; Szarzynski, Jörg
    The advancements and availability of geospatial technology and data, combined with a growing understanding of the importance of disaster management and disaster risk reduction, lead to an increase in quantity and quality of publications in spatial disaster risk assessments. This paper presents an overview of an in-depth bibliometric study of the global evolution of such spatial disaster risk assessments from 2000 to 2021. The study revealed an upwards trend in scientific production, with hydrological hazards dominating the research field. However, climate change may further drive research for meteorological and climatological hazards. No direct influence was found between major disasters and the number of assessments. The study also shed light on the conceptual frameworks that guided spatial risk assessments, with hazard and vulnerability being the essential components.
