The Khoury and Weltman (2004a and 2004b) Chameleon Model presents an addition to the gravitation force and was shown by the author (Robertson, 2009a and 2009b) to present a new means by which one can view other forces in the Universe. The Chameleon Model is basically a density-dependent model and while the idea is not new, this model is novel in that densities in the Universe to include the vacuum of space are viewed as scalar fields. Such an analogy gives the Chameleon scalar field, dark energy/dark matter like characteristics; fitting well within cosmological expansion theories. In respect to this forum, in this paper, it is shown how the Chameleon Model can be used to derive the thrust of a solid rocket motor. This presents a first step toward the development of new propulsion models using density variations verse mass ejection as the mechanism for thrust. Further, through the Chameleon Model connection, these new propulsion models can be tied to dark energy/dark matter toward new space propulsion systems utilizing the vacuum scalar field in a way understandable by engineers, the key toward the development of such systems. This paper provides corrections to the Chameleon rocket model in Robertson (2009b). [ABSTRACT FROM AUTHOR]

In this paper, the local fifth force model developed by the author (Robertson, 2009) for a static mass density is extended to time varying mass densities. The time varying mass density model allows for field-force effects due to the time variance of an object’s mass density and uses a concept know to electrical engineers as “Time Dilation and Retardation.” Time dilation and retardation (TDR) is used to describe the time delay effect on the ambient Chameleon field due to the changing of an object’s mass density. From this, hot-gas rocket equations are developed from the integration of the local fifth force and the TDR equations. [ABSTRACT FROM AUTHOR]

The article deals with a study which examined the possibilities and limits of social influence which resulted from the chameleon effect in computer-mediated communication. The synchronization of nonverbal cues in dyadic and group interactions was first described by Kendon in 1970 and LaFrance in 1982. In that study, individuals who had been mimicked were more helpful and generous towards others than were non-mimicked participants.
