Still in a close affinity with Martin Heidegger, his teacher, Jonas argued that modem technology bore some annoying characters. In line of this anxiety, Jonas suggested the importance of protecting life as an integral part of the ethical project he intended to build. Departing from his basic notion that human life is never separated from other organic life, Jonas has opened a wider space for ethical responsibilities towards life of the whole cosmos. In what sense is his notion of the responsibility towards the whole life should be understood is one of the aim of this paper. Baring in mind that Jonas developed his concept on life and human responsibility towards it as an argumentation against the development of technology, the social context in which modem technology finds its root is worthed to be discussed. It is concluded that separating ethics from ontology as many theorists and philosophers did so far has strengthened the old notion of human autonomy with its defects, and by that, the destruction of life seemed to be accepted as a consequence of it.展开更多

Two conceits （concetti） are considered in analyzing Tintoretto＇s female imagery： （1） a fanciful invention of musica extravaganza; and （2） a Venetian allegory of bellezza. The first part of the essay discusses the provenance of the painting and the second part presents an iconographical interpretation of the imagery. This essay also focuses on the iconography of the painting based on viewing the subject and does not postulate on its iconography based on disappeared paintings or on a speculative decorative cycle on the theme of Hercules. Relying on well-documented research on music in Venice, on Mannerist practices, and on art theories during Tintoretto＇s life, some intriguing observations are made about the painting.展开更多

Risk exists throughout the entire life cycle of the project. It is an important guarantee for the success of the project to establish a good risk management mechanism and the risk-based decision-making mechanism. Personal communication tries to connect various telecommunication services to people, one of the key technologies to realise personal communication is to establish an advanced intelligent network—a kind of communication network that can provide and deal with the intelligent new businesses.

The results show that the increasing of fluorene-vinylene unit leads to a red-shift in the spectra of absorption and fluorescence, and shortens the excited state lifetime. Meanwhile, two-photon fluorescence efficiency and two-photon absorption cross section of truxene based oligolners gradually enhance in company with the extension of π- conjugated length. In addition, the values of two-photon absorption cross section modeled on the sum-over-state approach agree well with the experimental ones. The results indicate multi-branched truxene based oligomers bearing organic materials for two-photon applications.展开更多

This invokes relentless efforts to further our understanding of the basic science of water. Current challenges to achieve a molecular picture of the peculiar properties and behavior of water are discussed herein, with a particular focus on the structure and dynamics of bulk and surface water, the molecular mechanisms of water wetting and splitting, application-oriented research on water decontamination and desalination, and the development of complementary techniques for probing water at the nanoscale.展开更多
