Dynamics of quantum discord of two coupled spin-1/2’s subjected to time-dependent magnetic fields
2019
Abstract We describe the dynamics of quantum discord of two interacting spin-1/2’s subjected to controllable time-dependent magnetic fields. The exact time evolution of discord is given for various input mixed states consisting of classical mixtures of two Bell states. The quantum discord manifests a complex oscillatory behaviour in time and is compared with that of quantum entanglement, measured by concurrence. The interplay of the action of the time-dependent magnetic fields and the spin-coupling mechanism in the occurrence and evolution of quantum correlations is examined in detail.
Groupthink and Project Performance: The Influence of Personal Traits and Interpersonal Ties
2015
Contains fulltext : 166103.pdf (Publisher’s version ) (Closed access) This study explores whether the negative impact of “groupthink concurrence-seeking behavior” (GTB) on business process reengineering (BPR) projects is affected by group members personal traits and interpersonal ties within the group. To this purpose we conduct and present the results of a longitudinal controlled field experiment over 18 BPR projects lasting 3 months and involving 18 teams comprising 71 first-year MBA students. The main contribution of this study is twofold. First, we explicitly consider and measure the core construct of groupthink phenomenon: that is, GTB. Existing organizational behavior literature has, …

La jurisprudencia existente acerca de la indumentaria del trabajador y otros elementos que afectan a su aspecto e imagen externa durante el trabajo
2021
Partiendo de la doctrina del “equilibrio de derechos” del Tribunal Constitucional sobre la solución de los conflictos de concurrencia entre derechos constitucionales, se analiza la jurisprudencia de los principales Tribunales acerca del conflicto entre la libertad de empresa y el derecho a la propia imagen del trabajador en relación la indumentaria de éste en el trabajo.
Supervision by the state prerogatives of french sports federations
2013
French sports federations have developed without any state intervention. They had their own prerogatives to organize competitions in their respective sporting discipline. By virtue of their association status, they were entirely governed by private law. However, following a decision taken in 1974 by the Board of State confirming the existence of a public service delegated to the federal structure, the legislation gradually devote the principle of granting their prerogatives by the Ministry of Sports through two acts: the ministerial approval and delegation of public service. Since the issuance of these acts is synonymous powers recognized federations by state law and that the delegation lea…
Sportsponsoring als Geschenksimulation und Status-Spiel
2003
Sportsponsoring wird in der Fachliteratur als wirtschaftlich-rational begrundetes Leistungs-Gegenleistungs-Verhaltnis definiert. In der Offentlichkeitsarbeit von Sponsoren ist aber vielfach zu beobachten, dass dieses Austauschverhaltnis als Geschenk dargestellt wird. Im folgenden Beitrag wird an Beispielen belegt, dass dieser Maskierung eines Geschafts als selbstlose Gabe ein anthropologisches Muster zugrunde liegt, das auf einem Prestigedefizit rein wirtschaftlichen Handelns beruht. Daraus resultiert die Notwendigkeit der Akkumulation symbolischen Kapitals in Form eines Firmen- und Markenbilds, das Analogien zur Produktion von Glaubenssystemen und kulturellen Gutern aufweist. Der Wettbewer…

Thermal entanglement of a spin-1/2 Ising–Heisenberg model on a symmetrical diamond chain
2011
International audience; The entanglement quantum properties of a spin-1/2 Ising-Heisenberg model on a symmetrical diamond chain were analyzed. Due to the separable nature of the Ising-type exchange interactions between neighboring Heisenberg dimers, calculation of the entanglement can be performed exactly for each individual dimer. Pairwise thermal entanglement was studied in terms of the isotropic Ising-Heisenberg model and analytical expressions for the concurrence (as a measure of bipartite entanglement) were obtained. The effects of external magnetic field H and next-nearest neighbor interaction J(m) between nodal Ising sites were considered. The ground state structure and entanglement …
