Theoretical methods for empirical state determination of entangled two-level systems are analyzed in relation to information theory. We show that hidden variable theories would lead to a Shannon index of correlation between the entangled subsystems which is larger than that predicted by quantum mechanics. Canonical representations which have maximal correlations are treated by the use of Schmidt and Hilbert-Schmidt decomposition of the entangled states, including especially the Bohm singlet state and the GHZ entangled states. We show that quantum mechanics does (...) not violate locality, but does violate realism. (shrink)

This article reviews the cultural agenda of the celebrated Dominican preacher Giovanni Dominici in fifteenth-century Florence. Central issues discussed include Dominici’s educational programme, his cultural propaganda, his interest in the visual arts and his opposition to the study of the classics, as expressed in his public popular preaching. The close examination of his cultural agenda discloses Dominici as the most extreme opponent of humanist studies.

Nanomedicine offers remarkable options for new therapeutic avenues. As methods in nanomedicine advance, ethical questions conjunctly arise. Nanomedicine is an exceptional niche in several aspects as it reflects risks and uncertainties not encountered in other areas of medical research or practice. Nanomedicine partially overlaps, partially interlocks and partially exceeds other medical disciplines. Some interpreters agree that advances in nanotechnology may pose varied ethical challenges, whilst others argue that these challenges are not new and that nanotechnology basically echoes recurrent bioethical dilemmas. (...) The purpose of this article is to discuss some of the ethical issues related to nanomedicine and to reflect on the question whether nanomedicine generates ethical challenges of new and unique nature. Such a determination should have implications on regulatory processes and professional conducts and protocols in the future. (shrink)

While preaching in Siena in 1427, the Franciscan preacher, Bernardino of Siena referred to a celebrated painting by Simone Martini. The specific painting was the Annunciation now in the Uffizi Gallery in Florence and originally located in Siena’s Cathedral. Bernardino referred to it in connection with schooling young girls in the virtue of modesty:You see she [the Virgin] does not gaze at the angel, but sits with that almost frightened pose. She knew well it was an angel, so why should (...) she be disturbed? What would she have done if it had been a man? Take her as an example, girls, of what you should do. Never talk to a man unless your father or mother is present.1Here Bernardino offered the image of the Virgin as a .. (shrink)
