Bifurcation analysis of chen's equation

Abstract: Anticontrol of chaos by making a nonchaotic system chaotic has led to the discovery of some new chaotic systems, particularly the continuous-time three-dimensional autonomous Chen's equation with only two quadratic terms. This paper further investigates some basic dynamical properties and various bifurcations of Chen's equation, thereby revealing its different features from some other chaotic models such as its origin, the Lorenz system.

Resistance to Brand Switching When a Radically New Brand is Introduced: A Social Identity Theory Perspective

Abstract: There has been little research on how market disruptions affect customer–brand relationships and how brand loyalty may be sustained when disruptions occur. Drawing from social identity theory and the brand loyalty literature, the authors propose a conceptual framework to examine these questions in a specific market disruption, the introduction of a radically new brand. The framework focuses on the time-varying effects of customers’ identification with and perceived value of the incumbent relative to the new brand on switching behavior. The authors divert from the conventional economic perspective of treating brand switching as functional utility maximization to propose that brand switching can also manifest customers’ social mobility between brand identities. Results from longitudinal data of 679 customers during the launch of the iPhone in Spain show that both relative customer–brand identification and relative perceived value of the incumbent inhibit switching behavior, but their effects vary over time. Relative customer–brand identification with the incumbent apparently exerts a stronger longitudinal restraint on switching behavior than relative perceived value of the incumbent. The study has important strategic implications on devising customer relationship strategies and brand investment.
