Integrating Construal-level Theory in Designing Fear Appeals in IS Security Research

Organizations increasingly use fear appeals to motivate users to engage in behaviors that protect information security. Though academic interest in the topic has burgeoned, prior research has mainly focused on providing process evidence on how low- and high-threat security messages influence protective behaviors. According to protection motivation theory, however, the threat-appraisal phase, in which the receiver evaluates whether a fear appeal is threatening or not, follows exposure to the fear appeal. One can indeed design fear appeals to manipulate different dimensions, including the threat depicted and the coping response provided. These dimensions, in turn, influence protection motivation. The general focus on low- and high-threat messages runs the risks of 1) foregoing key theoretical insights that can stem from specific message manipulations and 2) inadvertently introducing message confounds. To address this issue, we introduce construal-level theory as the theoretical lens to design and identify potential confounds in fear-appeal manipulations. We further discuss how researchers can seamlessly integrate construal-level theory into information security studies based on protection motivation theory. Our work has important theoretical and methodological implications for IS security researchers

Multi-time delay, multi-point Linear Stochastic Estimation of a cavity shear layer velocity from wall-pressure measurements

Multi-time-delay Linear Stochastic Estimation (MTD-LSE) technique is thoroughly described, focusing on its fundamental properties and potentialities. In the multi-time-delay ap- proach, the estimate of the temporal evolution of the velocity at a given location in the flow field is obtained from multiple past samples of the unconditional sources. The technique is applied to estimate the velocity in a cavity shear layer flow, based on wall-pressure measurements from multiple sensor

Developing improvisation skills:the influence of individual orientations

The growing relevance of improvisation for successful organizing calls for a better understanding of how individuals develop improvisation skills. While research has investigated the role of training and simulations, little is known about how individuals develop improvisation skills when formal training is not an option and how individual-level factors shape development trajectories. We explore these issues in a longitudinal qualitative analysis of live action role-playing. Our findings reveal a three-stage process of improvisation development shaped by the presence of task and social structures, which act as both constraints and resources. Moreover, our findings illuminate how collaborative and competitive orientations shape whether improvisers perceive these structures as a resource that they need to nurture and renew (i.e., collaborative) or to seize and exploit (i.e., competitive). We also show that individual orientations are not always enduring but can change over time, engendering four types of improvisation development trajectories. Our work provides a longitudinal account of how individual orientations shape the process of improvisation development. In so doing, we also explain why individuals who are skilled improvisers do not necessarily improvise effectively as a collective, and we reconcile different conceptualizations of improvisation
