L'Intelligenza Artificiale in Sanità: il Ruolo dei Dati
No full textNell'era della Artificial Intelligence (AI) le nuove questioni etiche, la loro traduzione in mediazione giuridica ed il dilatarsi della scienza e della prassi applicativa esigono, si afferma sempre, un approccio interdisciplinare. Eppure, la ormai sterminata letteratura in materia affronta sovente i problemi da angoli visuali particulari. Il volume, pur dedicato ad indagine settoriale, teoria e prassi dell’impiego di device AI-powered in medicina, si sforza di censire, facendole fondere in un unitario (con)testo, le voci di saperi convergenti ma settorialmente distinti: esponenti dell’ars medica e delle scienze informatiche ed ingegneristiche si affiancano a giuristi e studiosi della nuova algoretica, completandosi a vicenda ed arricchendosi della reciproca somma sinergica
Virtual Distro Dispatcher: A Costless Distributed Virtual Environment from Trashware
No full textObsolete hardware can be effectively reused through intelligent software optimization, which is possible only when source code is available. Virtual Distro Dispatcher (VDD) is a system that produces virtual machines on a central server and projects them on a number of costless physical terminals. VDD is the result of an extreme software optimisation based on virtualization and terminal servers. VDD creates and projects Linux distros that are completely customizable and different from each other. They are virtual desktop machines that can be used for testing or developing and are completely controllable directly from each terminal. Memory consumption has been strongly reduced without sacrificing performances. Test results are encouraging to proceed with the research towards clustering. © Springer-Verlag Berlin Heidelberg 2007
Shared Images and Camera Fingerprinting May Lead to Privacy Issues.
No full textSocial networks have become an indispensable part of everyday life by providing users with different types of interaction. However, sharing different types of data, such as text, image, video and etc., on social networks, gives rise to user privacy concerns and risks, while the user is not aware of that. In this chapter, we show how the images shared by users can be applied to fingerprint the acquisition devices and link user profiles on social networks
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
