The never ending growth of digital information and the availability of low-cost storage facilities and networks capacity is leading users towards moving their data to remote storage resources. Since users’ data often holds identity-related information, several privacy issues arise when data can be stored in untrusted domains. In addition digital identity management is becoming extremely complicated due to the identity replicas proliferation necessary to get authentication in different domains. GMail and Amazon Web Services, for instance, are two examples of online (...) services adopted by million of users throughout the world which hold huge amounts of sensitive users data. State-of-the-art encryption tools for large-scale distributed infrastructures allow users to encrypt content locally before storing it on a remote untrusted repository. This approach can experience performance drawbacks, when very large data-sets must be encrypted/decrypted on a single machine. The proposed approach extends the existing solutions by providing two additional features: (1) the encryption can also be delegated to a pool of remote trusted computing resources, and (2) the definition of the encryption context which drives the tool to select the best strategy to process the data. The performance benchmarks are based on the results of tests carried out both on a local workstation and on the Grid INFN Laboratory for Dissemination Activities (GILDA) testbed. (shrink)
The complex world of thought and sensitivity in the sphere of contemporary art has entailed the revision and exclusion of disciplines aimed at providing a model to explain and conceptualize reality. Art history, as one such discipline, has had many of its contributions questioned from Gombrich’s epistemological reformulation to the postmodern discourses, which extol the death of the author, the post-structuralist idea of tradition as a textual phenomenon, and the declaration of the death of history as a consequence of the (...) hybridization of disciplines and of other bran- ches of human knowledge. Nevertheless, it can be demonstrated that proposals as those by Julius von Schlosser and Giulio Carlo Argan enclose reflections and methodological aspects which can help us face the task of understanding and visualizing the mediating role of historians in the culture of sensitivity, and the art modulations that have resulted from the blows of history and that, in turn, have shaped both art and art history into what they are or can be to us today.

Unlike similar works, Xingxue Cushu 性學觕述 by the Italian Jesuit missionary Giulio Aleni sought to deliver the Christian doctrine into China by introducing Western medicine. The conflict between the Christian concept of the soul and the traditional psychic concept in China made the task difficult. Scholasticism rejects the idea that an individual’s soul may be physically divided or localized, whereas the Chinese tradition largely assumes the contrary and regards the heart as the center of one’s psychic powers or vitality. (...) Aleni addressed this conflict by reducing the mind to the function of the brain for sensitive memory. Chinese physicians accepted Aleni’s concept of brain-related memory. However, his claim of an immaterial soul was ignored, and the Western connection between brain and memory was misinterpreted and subjected to Chinese cardiocentrism; thus, the physically centered psychic concept that underlies Chinese philosophy persisted.

This paper discusses the positions of Italian philosopher Giulio Preti (1911?1972) in relation to the quarrel between Analytic and Continental philosophy. Preti?s thought appears as a systematic thought permitting to overcome, through his logical, epistemological and linguistic reflection, the divide between these two approaches. The different features of his philosophy are analyzed here in detail and compared to the main theoretical assumptions of Analytic and Continental philosophy.
This appreciation outlines the life and work of Giulio Preti, a philosopher of the critical rationalist movement. His was a tormented and conflictual philosophical itinerary from his intellectual roots in 1930s Italy, via the philosophical journal Studi filosofici in the 1940s, to his major works Praxis and Empiricism and Rhetoric and Logic in the 1950s and 1960s. His anxiety about the ambiguity of contemporary reality, it is suggested, is also ours.
Ian Hacking sets out a parallel between Michel Foucault’s thought and that of Giulio Preti based on the debate between them that took place in 1971. This is the speech given at the award of the ‘Giulio Preti’ Prize in November 2008.
With the arrival of the fourth volume of this work, Peter Lombard's Sentences is now fully available in English for the first time. Giulio Silano's text, based on the third critical edition by Ignatius C. Brady in two volumes (Grottaferrata, 1971-81) is distinguished by its accuracy and readability, meeting the exacting criteria of a Pontifical Institute of Mediaeval Studies translation. Each volume has a detailed table of contents, an index of biblical and patristic references, and a full bibliography of (...) English translations of sources cited in the text along with on-line versions where they exist. Volume 1 contains a bibliography of Anglophone scholarship pertinent to the Lombard, not updated in volume 4. .. (shrink)
The present article considers Giulio Racah’s contributions to general physical theory and his establishment of theoretical physics as a discipline in Israel. Racah developed mathematical methods that are based on tensor operators and continuous groups. These methods revolutionized spectroscopy. Currently, these are essential research tools in atomic, nuclear and elementary particle physics. He himself applied them to modernizing theoretical atomic spectroscopy. Racah laid the foundations of theoretical physics in Israel. He educated several generations of Israeli physicists, and put Israel (...) on the world map of physics. (shrink)
