Quantifying High-Order Interactions in Cardiovascular and Cerebrovascular Networks

2022

We present a method to analyze the dynamics of physiological networks beyond the framework of pairwise interactions. Our method defines the so-called O-information rate (OIR) as a measure of the higher-order interaction among several physiological variables. The OIR measure is computed from the vector autoregressive representation of multiple time series, and is applied to the network formed by heart period, systolic and diastolic arterial pressure, respiration and cerebral blood flow variability series measured in healthy subjects at rest and after head-up tilt. Our results document that cardiovascular, cerebrovascular and respiratory interactions are highly redundant, and that redundancy …

La libertà di espressione in rete fra content moderation dei social network e regolazione dell’Unione Europea

2022

Starting from the premise that digital society and advances in technology determine the need for adaptation, even if only in an interpretative sense, of the legal categories of constitutionalism, the study analyzes the new dimension of the freedom of expression of thought in the "digital environment". Through the examination of the different jurisprudential approaches expressed to protect this freedom in Europe and in the United States, the work also examines the role of social platforms, their power of self-regulation and that of content moderation, which will highlight the need for regulation of the phenomenon that balances the needs of protection of rights and those of technological adva…

La libertà di espressione nell’era dei social network fra content moderation e necessità di una regolazione flessibile

2023

Starting from the premise that digital society and advances in technology determine the need for adaptation, even if only in an interpretative sense, of the legal categories of constitutionalism, the study analyzes the new dimension of the freedom of expression of thought in the “digital environment”. Through the examination of the different jurisprudential approaches expressed to protect this freedom in Europe and in the United States, the work also examines the role of social platforms, their power of self-regulation and that of content moderation, which will highlight the need for regulation of the phenomenon that balances the needs of protection of rights and those of technological adva…

Significati vecchi e nuovi di ideologia: una rassegna

2020

Old ideologies, defined as «grand narratives», seem to have faded away, but this is not a conclusive argument to state that ideology has, itself, disappeared. In fact, there are strong reasons to believe that it has not. In the first part, this article offers a synthetic survey of some of the most significant conceptions of ideology in order to avoid the confusion generated by uncritical uses of the term. The vantage point of the analysis is the fundamental conceptual opposition between «ideology» and «praxis» («truth», or «reality»). The second part of the article opens up some questions about how the new forms of ideology may thrive in the new spaces created by the communication technolog…

FACEBOOK AT THE TIME OF "DIGITAL NATIVES": TEACHING SPANISH THROUGH SOCIAL NETWORKS

2015

Language acquisition is a process which is influenced by cognitive, attitudinal, demographic, linguistic and experiential factors. At the time of globalization, structural change occurred with the advent of the technological revolution, the subsequent introduction of innovative tools in teaching, have transformed the concept of learning. At the web's century youngers, "digital natives", are creating a kind of "parallel school" not only to access to knowledge, to collaborate with users and discuss, but also to teach and learn languages through social networks, blogs, fora and communities, as if they were in a virtual classroom. As to the acquisition of Spanish as a L2, analysing the most rec…

The Dimensions of Facebook Addiction as Measured by Facebook Addiction Italian Questionnaire and Their Relationships with Individual Differences

2017

Abstract The studies reported analyze the factorial structure of Facebook Addiction Italian Questionnaire (FAIQ), a variant of 20-item Young's Internet Addiction Test (IAT). In Study 1, we tested FAIQ psychometric properties using exploratory factor analysis (EFA). In Study 2, we performed a confirmatory factor analysis (CFA) to verify the FAIQ factorial structure identified through EFA. Results from CFA confirm the presence of a four-factor model accounting for 58 percent of total variance, plus a general higher order factor that best fits the data. Further relationships between FAIQ factor scores, personality, and Facebook usage have been explored.

Does Attentional Style Moderate the Relationship between Time Perspective and Social Network Addiction? A Cross-Sectional Study on a Sample of Social…

2021

The present study investigates the role of attentional style as a moderator variable between temporal perspective and social network addiction, since little is known about users’ cognitive variables involved in this kind of addictive behavior. To achieve this goal, a sample of 186 volunteers and anonymous social networking sites users (M = 34%; F = 66%; Mage = 22.54 years; SD = 3.94; range: 18 ÷ 45 years) participated in a cross-sectional study. All participants filled out self-report instruments measuring temporal perspective, internal vs. external attentional style, and social network addiction. The results align with the previous literature and show that present fatalistic and past negat…

Facebook as a Small World: a topological hypothesis

2011

Facebook is becoming a pervasive entity as its social, cultural and media ramifications grow deep and entrenched in our daily life. Its nature of a complex system of interactions, bearing a strong similarity to networks built through individual choices and systems shaped by evolu- tionary pressure, makes it an interesting target for research. Scale-free Small World networks, recently popularized by Barabasi, are a topological class pertaining to both these domains, whose members have resilience to disruption and short intermediate connections between nodes. In this paper we show that the topological structure of a specific subset of Facebook, gathered using data from a self-report online qu…
