The case recounts an incident of theft at a CEOs home during a company party. The rogue may well be an employee, and the CEO considers his options: should he let the matter pass and preserve the good will generated by the party, or should he stand on principle and engage the issue frontally? Three commentators provide perspective on an optimal response. They consider whether the CEOs true intent is to show appreciation or showcase opulence. In addition, the aberrant behavior (...) at this celebratory event suggests some measures that management might take in the workplace. (shrink)

The fine structure constant α ≡ e2/ c ≈ 1/137 is one of the fundamental parameters of the standard model of particle physics. There is a long history of attempts to derive the measured value of α from an underlying theory, or exhibit it in the form of a compact mathematical expression [2–4, 6, 8, 14–16]. The most significant advance in this endeavour was made by Dirac, who showed that if magnetic monopoles exist, with magnetic charge μ, then..

Using a model quantum clock, I show how the velocity of a relativistic particle can be measured. The results are used to analyse the long-standing problem of the velocity..

Using a model quantum clock, I evaluate an expression for the time of a nonrelativistic quantum particle to transit a piecewise geodesic path in a background gravitational field with small spacetime curvature (gravity gradient), in the case that the apparatus is in free fall. This calculation complements and extends an earlier one (Davies 2004) in which the apparatus is fixed to the surface of the Earth. The result confirms that, for particle velocities not too low, the quantum and classical transit (...) times coincide, in conformity with the principle of equivalence. I also calculate the quantum corrections to the transit time when the de Broglie wavelengths are long enough to probe the spacetime curvature. The results are compared with the calculation of Chiao and Speliotopoulos (2003), who propose an experiment to measure the foregoing effects. (shrink)

L'article explore le sens que peut avoir le symbole du Règne de Dieu aujourd'hui dans le contexte asiatique. Après une courte histoire du symbole, l'article présente six défis que l'Asie pose à son usage en un discours théologique en contexte asiatique. La seconde partie passe en revue l'usage fait du symbole du Règne de Dieu par certains théologiens asiatiques contemporains: les théologiens Tissa Balasuriya et Aloysius Pieris du Sri Lanka, les théologiens Coréens du minjung, et le théologien presbytérien du Taiwan (...) Choan-Seng Song. En se basant sur les oeuvres de ces théologiens et à la suite de la théologie de la libération, la dernière partie essaie de montrer comment les six défis posés plus tôt peuvent être résolus dans la perspective de la philosophie confucianiste.

Inconsistencies in the usual interpretation of the absorber theory of radiation are exposed which invalidate an experiment proposed recently by Heron and Pegg. An earlier experiment by Partridge necessarily gave a null result owing to absorption on the far side of the Earth of any advanced radiation which may have been present.
