The effects of self-efficacy on computer usage
1995
Abstract This paper examines the effect of self-efficacy, belief in one's capabilities of using a computer in the accomplishment of specific tasks, on computer usage. It introduces an extended technology acceptance model (TAM) that explicitly incorporates self-efficacy and its determinants (experience and organizational support) as factors affecting computer anxiety, perceived ease of use, perceived usefulness and the use of computer technology. A survey of 450 microcomputer users in Finland found strong support for the conceptual model. In accordance with TAM, perceived usefulness had a strong direct effect on usage, while perceived ease of use had indirect effect on usage through perceive…
Bot or not? a case study on bot recognition from web session logs
2018
This work reports on a study of web usage logs to verify whether it is possible to achieve good recognition rates in the task of distinguishing between human users and automated bots using computational intelligence techniques. Two problem statements are given, offline (for completed sessions) and on-line (for sequences of individual HTTP requests). The former is solved with several standard computational intelligence tools. For the second, a learning version of Wald’s sequential probability ratio test is used.
Phase Coherence in Conceptual Spaces for Conversational Agents
2010
This chapter attempts to enhance the traditional chatbots with associative/intuitive capabilities. According to these considerations, it tries to create a conversational agent model that takes into consideration, aside from the traditional rule - based dialogue mechanism, also some sort of intuitive reasoning ability. The aim is in attempting to overcome the rigid pattern - matching rules, proposing a "phase coherence" paradigm into a semantic space. With this locution the chapter intend that the vectors representing the elements of the dialogue are coherent with the context. The chapter trust that this intuitive - associative capability can be obtained using the LSA methodology. The repres…
Parole e potere. Libertà d'espressione, hate speech e fake news

indagine in tema di libertà di espressone che parte dalle origini del costituzionalismo contemporaneo e si muove poi lungo le coordinate relative alla giurisprudenza della Corte suprema statunitense e delle Corti europee, nel processo di transizione dell’esercizio di diritti e libertà fondamentali dal mondo degli atomi a quello dei bit. investigation on the subject of freedom of expression that starts from the origins of contemporary constitutionalism and then moves along the coordinates relating to the jurisprudence of the US Supreme Court and the European Courts, in the transition process of the exercise of fundamental rights and freedoms from the world of atoms to that of bits.

Il software “Sviluppare l’Intelligenza Emotiva”: usabilita’, gradevolezza e primi dati empirici.
2008
Introduzione: Il software “Sviluppare l’intelligenza emotiva” (D’Amico e De Caro, 2008), è il primo strumento multimediale composto da un modulo di assessment ed un percorso di training sui quattro “rami” dell’Intelligenza Emotiva (IE), definiti nel modello di Mayer e Salovey (1997) quali: percezione, comprensione, uso e gestione delle emozioni.Nel presente studio-pilota viene riportata la prima esperienza di utilizzo del modulo di assessment del software.Metodo: In un'unica sessione individuale, 74 studenti delle tre classi di scuola secondaria di primo grado hanno compilato, assistiti da uno sperimentatore, la prova e un breve questionario. Il modulo di assessment è composto da una totale…
Una certa reciprocità di saperi: dalla lotta a terrorismo e mafia ai metodi investigativi tra Italia e Stati Uniti
2021
This essay is divided into two parts. The first investigates the circularity of knowledge, techniques and men in the fight against the mafia and terrorism. The second part isolates one of these tools, perhaps the most important, in the use of "pentiti", to include it in the circularity of experiences with the repression of organized crime in the United States and then in the Italian controversies on the political use of collaborators with justice.

Optimisation des requêtes de similarité dans les espaces métriques répondant aux besoins des usagers
2012
The complexity of data stored in large databases has increased at very fast paces. Hence, operations more elaborated than traditional queries are essential in order to extract all required information from the database. Therefore, the interest of the database community in similarity search has increased significantly. Two of the well-known types of similarity search are the Range (Rq) and the k-Nearest Neighbor (kNNq) queries, which, as any of the traditional ones, can be sped up by indexing structures of the Database Management System (DBMS). Another way of speeding up queries is to perform query optimization. In this process, metrics about data are collected and employed to adjust the par…
