At-risk brand relationships and threats to the bottom line

Like a stock portfolio, each relationship type offers a brand higher or lower growth opportunities and risks. The type of relationship is particularly relevant in brand crisis events. When a brand is hit by a crisis, it is not necessarily the most successful strategy to focus exclusively on protecting positive emotional relationships. At-risk relationships are affected more than others and can lead to a significant decline of brand value. Our cases highlight that at-risk relationships represent a critical, but often overlooked, aspect of a brand’s relationship portfolio. Risks range from negative word of mouth that might have a negative impact on potential new customers to clear retention risk. Marketers should manage these risks proactively by identifying and investigating the nature of their customer relationships and by responding frankly and credibly to crisis events.Published versio

The Adaptive Transient Hough method for long-duration gravitational wave transients

This paper describes a new semi-coherent method to search for transient gravitational waves of intermediate duration (hours to days). In order to search for newborn isolated neutron stars with their possibly very rapid spin-down, we model the frequency evolution as a power law. The search uses short Fourier transforms from the output of ground-based gravitational wave detectors and applies a weighted Hough transform, also taking into account the signal's amplitude evolution. We present the technical details for implementing the algorithm, its statistical properties, and a sensitivity estimate. A first example application of this method was in the search for GW170817 post-merger signals, and we verify the estimated sensitivity with simulated signals for this case.Comment: 13 pages, 14 figure
