Abstract
This paper provides an explanation for noisy pricing based on the strategic interaction of two firms competing in prices. When a firm adds noise to its prices, undercutting it becomes harder. Therefore, noisy pricing allows a firm to either exclude a competitor while charging supracompetitive prices, or to soften competition and have both firms earn supracompetitive profits. Such behavior leads to prices lying between competitive and monopolistic levels, and harms consumers and social welfare. It occurs in equilibrium if firms set prices sequentially, and in some equilibria of a repeated game of simultaneous price-setting if one firm is patient.

Argues that the "principia of history" are marked by the dualism represented by the "sacred madness" of elites on the one hand and practices of "taming the profane" on the other. These principia shape the symbolic, political, and social knots of reality that converge and thus produce the common "reality" of historical interferences.

Considers prevailing interpretations of time, which apparently represent the impact of intellectualism in spite of being quite diverse. It is under its influence that time is replaced by an intellectual function. The universals of time forms are defined by the lubrication dogma (the past, the present, the future), which specify the nature of knowledge in the technology format. The mechanical universality deprives time of its emotional and aesthetic dimensions.

Natural Stress Relief (NSR) Meditation, a mental technique practiced for 15 minutes twice a day, reduces stress and anxiety by inducing a physiological state of deep rest. Regular practice of this technique appears to reduce trait anxiety and to develop qualities associated with self-actualization,
such as inner peace, satisfaction, and creativity. This article reports new research that documents this effect using psychometric measures. A group of 31 practitioners showed, after four weeks of regular practice, a significant reduction of trait anxiety as measured by the State-Trait Anxiety
Inventory (STAI; Spielberger, Gorsuch, Lushene, Vagg, & Jacobs, 1983) (effect size d = .69, calculated following Cohen), and a significant increase of self-actualization as measured by the Jones and Crandall (1986) Short Index of Self-Actualization (SISA; effect size d =
.47).
