Information technology e social media nell'evoluzione del reporting
No full textCome indicato nell'introduzione del capitolo, attraverso il lavoro "si vuole evidenziare come IT e social media contribuiscano a sviluppare e curare coese comunità d’interessi, fondamentali per l’evoluzione della consapevolezza sociale, della qualità delle decisioni, dei processi di reporting integrato degli atenei. Accanto a evidenti vantaggi, IT e social media presentano limiti e rischi che tuttavia non ne inficiano la validità, ma semplicemente indirizzano verso condizioni necessarie per permettere un’efficace interazione tra gli attori e la convergenza degli stessi verso interessi di rilevanza sociale"

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
Supporting Tutoring by Improved Statistical Analysis of Discussion Forums.
No full textFostering collaboration among pupils in a Learning Management System is certainly a great challenge for tutors and teachers. In order to assist the instructors in this task, a possible solution might consists in a technological artefact which could support the tutoring process at different levels.\ud
Unfortunately, while the research has spent a great effort to the techniques devoted to manage knowledge, less attention has been focused on making the process of creation of new knowledge – and the reflection on such process – more effective. Moreover, the concept of level of collaboration in a virtual community is hard to be descrive in terms of a formal representation suitable for a software implementation. In addition, such implementation should be computationally efficient because the available time during the interaction is limited.\ud
In this research, a possible solution is pursued by isolating the most interesting phases that occur during a forum session from a collaborative standpoint and finding out the necessary conditions on their basis. Then, such empirical observation are used for implementing a software library which measures such conditions and suggests the current phase according to an internal representation of the evolution of collaboration inside a learning community. From a formal point of view, the metrics adopted are based on the statistical analysis of the language used in the messages and on the dynamics of posting of the contributes.\ud
Despite the simplicity of this approach, the results obtained are encouraging because\ud

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
Fashion e sostenibilità: opportunità offerte dalla tecnologia blockchain
Full text linkCosa sappiamo, come consumatori, della storia delle materie utilizzate negli abiti, dei cicli che il prodotto che stiamo comprando o usando sta o non sta permettendo di chiudere? Come accedere ad etichette di dettaglio? Come controllare il ricorso a materiali, strutture e processi non inquinanti per l’ambiente? Non ultimo, sviluppati brand sostenibili, come tutelarli dalla contraffazione? Tantissime sono le domande di chi si preoccupa di un consumo di moda che sia sostenibile. In particolare, in questo lavoro si tratta della tecnologia blockchain e del contributo che può offrire per favorire la tracciabilità – dei prodotti, del riciclo, del riuso – e aumentare la trasparenza delle filiere per i consumatori e i produttori
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
