Two Stories of Cancel Culture. How Value-Driven Calls to Cancel Affect the Bottom Line
[EN] Social media has become the environment for value-driven polemics that have been commonly dubbed cancel culture. As a construct, cancel culture has little empirical research especially as it relates to the efficacy of the calls to cancel a business. This research analyzes a successful call to cancel, evidenced in a break in sales for Abercrombie & Fitch, and an unsuccessful call to cancel directed toward Starbucks. The sentiments of tweets for both companies were reduced to a valenced level for the core emotions, using a one-dimensional k-mean clustering, for each fiscal quarter. Correlational and time-series analysis was performed. A successful call to cancel showed a structural break in sales but not in Altman’s z-score. The polemic differences in the emotions were strongly correlated to sales for the successful call to cancel but were not present in the unsuccessful case. Likewise, the time-series analysis showed Granger-causality between emotions and the sales for a successful call to cancel. In both the successful and unsuccessful campaigns, individual emotions were ultimately found to be representing two factors present in the 8-emotion model- positive and negative sentiment. This research supports the threshold model of consumer decision-making while calling into question the granular nature of emotions.Reyes-Fournier, P.; Reyes-Fournier, E.; Bracken, D. (2023).

Effect of Tail Dihedral on Lateral Control Effectiveness at High Subsonic Speeds of Differentially Deflected Horizontal-Tail Surfaces on a Configuration having a Thin Highly Tapered Wing
Tests have been conducted in the Langley high-speed 7- by 10-foot tunnel to determine the effect of tail dihedral on lateral control effectiveness of a complete-model configuration having differentially deflected horizontal-tail surfaces. Limited tests were made to determine the lateral characteristics as well as the longitudinal characteristics in sideslip. The wing had an aspect ratio of 3, a taper ratio of 0.14, 28.80 deg sweep of the quarter-chord line with zero sweep at the 80-percent-chord line, and NACA 65A004 airfoil sections. The test Mach number range extended from 0.60 to 0.92. There are only small variations in the roll effectiveness parameter C(sub iota delta) with negative tail dihedral angle. The tail size used on the test model, however, is perhaps inadequate for providing the roll rates specified by current military requirements at subsonic speeds. The lateral aerodynamic characteristics were essentially constant throughout the range of sideslip angle from 12 deg to -12 deg. A general increase in yawing moment was noted with increased negative dihedral throughout the Mach number range
