Assessment of Cardiorespiratory Interactions During Spontaneous and Controlled Breathing: Non-linear Model-free Analysis

2022

In this work, nonlinear model-free methods for bivariate time series analysis have been applied to study cardiorespiratory interactions. Specifically, entropy-based (i.e. Transfer Entropy and Cross Entropy) and Convergent Cross Mapping asymmetric coupling measures have been computed on heart rate and breathing time series extracted from electrocardiographic (ECG) and respiratory signals acquired on 19 young healthy subjects during an experimental protocol including spontaneous and controlled breathing conditions. Results evidence a bidirectional nature of cardiorespiratory interactions, and highlight clear similarities and differences among the three considered measures.

Assessment of Cardiorespiratory Interactions During Spontaneous and Controlled Breathing: Linear Parametric Analysis

2022

In this work, we perform a linear parametric analysis of cardiorespiratory interactions in bivariate time series of heart period (HP) and respiration (RESP) measured in 19 healthy subjects during spontaneous breathing and controlled breathing at varying breathing frequency. The analysis is carried out computing measures of the total and causal interaction between HP and RESP variability in both time and frequency domains (low- and high-frequency, LF and HF). Results highlight strong cardiorespiratory interactions in the time domain and within the HF band that are not affected by the paced breathing condition. Interactions in the LF band are weaker and prevalent along the direction from HP t…

Adrano, Efesto e i Palici. Culti, interazioni etniche e middle ground nella Sicilia antica

2015

Stranieri o nativi che fossero (εἴτε εἶεν ξένοι εἴτε ἐπιχώριοι), coloro che si accostavano ai santuari dei Palici, di Adrano e di Efesto assumevano un atteggiamento ricettivo e fiducioso, effetto di una strategia “macroretorica” che offriva forme di transazione e di mediazione in un quadro diffuso di conflittualità tra individui e tra gruppi. In questo volume, il ricorso al modello interpretativo del middle ground e al concetto di “porosità” culturale mostra che sia le comunità indigene sia quelle greche si ridefinivano in modi differenti nei diversi contesti spazio-temporali e adattavano la propria struttura identitaria alle più svariate circostanze: dal punto di vista di una “ecologia cul…

Contatti culturali, identità e popolamento nel territorio imerese

2016

Il lavoro prende in considerazione il problema dei rapporti tra coloni greci e comunità indigene nel territorio di Himera, sulla base dei risultati della prospezione archeologica condotta per tre decenni nelle valli dei fiumi Imera settentrionale, Torto e S. Leonardo. Vengono esaminati gli elementi di cultura materiale che permettono di definire i modi dell'interazione culturale tra coloni e indigeni, nonché di ricostruire i paesaggi politici, socio-economici e il paesaggio del sacro nelle diverse aree indagate e nei diversi comprensori. La ricerca infatti permette di delineare, oltre alle usuali organizzazioni insediative e agricole della chora politiké e della éremos chora, anche articola…

Settore L-ANT/09 - Topografia AnticaSettore L-ANT/07 - Archeologia ClassicaThis work focuses on the problem of cultural contacts between Greek colonists and indigenous communities in the territory of Himera based on the results of the archaeological survey conducted for three decades in the valleys of the northern Imera Torto and S. Leonardo rivers. The elements of material culture that enable us to define the ways of cultural interaction between settlers and indigenous peoples as well as to reconstruct the political socio-economic and sacred landscapes in the various districts investigated are examined. In fact the research allows to outline in addition to the usual settlement and agricultural organizations of chora politiké and éremos chora articulated areas within the territory of Himera and to understand the landmarks of the rural settlement alongside the presence of highland settlements . Therefore the center-periphery approach is abandoned for a more articulated analysis demonstrating different forms of settlement and cultural contact in the three river valleys of the Himera hinterland.

La negoziazione dei significati nell’intervista sociolingustica: dinamiche interazionali e influenze contestuali nei dati dell’Atlante Linguistico de…

2020

In this article I discuss some interactional aspects regarding the relation between the participants in the sociolinguistic interview. In particular, I show how interviewers and interviewees work together in order to co-construct the (socio)linguistic data. In this perspective, I analyse the ways in which the participants make observable to each other their interactional roles through the interview. Moreover, I focus on the relation between the individuals taking part in the interview and the invisible, yet influential members of the research group. I show how the latter may affect the interactional moves of the former, but also how participants account for the research group’s role. The an…

I marginalia di Dino Buzzati: schemi, illustrazioni e disegni

2022

Secondo questa proposta di lettura dell'opera grafica di Dino Buzzati, che può essere estesa anche ad altri autori dal doppio talento, i disegni ai margini della scrittura possono essere interpretati allora nella loro funzione di relazione tra le arti che si risolve in una interazione, una negoziazione, uno slittamento oppure un conflitto, una cancellatura. Inoltre le annotazioni ai margini della scrittura, soprattutto nelle loro versioni grafiche, costituiscono una forma di introspezione autobiografica assai preziosa per ricostruire il profilo del loro autore, se scrittore e disegnatore al contempo.

Settore L-FIL-LET/14 - Critica Letteraria E Letterature ComparateAccording to this proposed analysis of Dino Buzzati's graphic work which can also be extended to other doubly talented authors the drawings at the margins of writing can be interpreted then in their function as a relationship between the arts that results in an interaction a negotiation a slippage or a conflict an erasure. Moreover annotations in the margins of writing especially in their graphic versions constitute a form of autobiographical introspection that is very valuable for reconstructing the profile of their author if writer and artist at the same time.

Software e design: i media digitali nel quotidiano

2015

L’oggetto che oggi maggiormente caratterizza la quotidianità è senza dubbio il computer (sotto forma di pc, tablet, smartphone, ecc.); esso è determinato dal software che lo fa funzionare e che determina i modi dell’esperienza dell’utente. Comprendere gli oggetti digitali significa dunque comprendere il software in ogni sua dimensione: la sua progettazione, le opportunità che crea, i vincoli che impone e che di conseguenza consentono un utilizzo consapevole di questi oggetti. Computer, tablet, smartphone are the most important everyday objects in our life because we made experiences by them; they run due to their software: so it is necessary to understand it, his form, his design and his tr…

Rappresentazioni e territorio nelle dinamiche del turismo: il caso della Lonely Planet Sicily

2018

L’attuale dibattito sul riordino territoriale del Paese rende nuovamente centrale il concetto di territorio che, da sempre, in una prospettiva geografica pone problemi definitori. Esso può essere, infatti, oggetto di produzioni simboliche e (ri)semantizzazioni in grado di ridefinirlo e di creare specifiche modalità di interazione. A questo proposito, il presente lavoro intende proporre una riflessione su alcune dinamiche di produzione e riproduzione simbolica che interessano il concetto di territorio nel turismo, ambito in cui si può osservare una relazione diretta tra rappresentazione del territorio (intesa anche come narrazione) e possibilità d’azione. In particolare, attraverso il caso s…

Settore M-GGR/02 - Geografia Economico-PoliticaThe current debate about the Italian territorial reorganization makes again fundamental the concept of «territory». This paper aims to reflect on some important dynamics that concern the idea of territory. More in particular I explore in which form it can be (re)semantised through some tourism representations and narrations able to create specific ways of interaction. By taking into account the case study of the Lonely Planet 2017 digital tourist guidebook dedicated to Sicily that splits (and reorganizes) the island in smaller «regions» it is possible to reflect on a complex space dynamic able to redefine the same idea of territory. Indeed the tourist guidebook uses both texts and geographical maps to propose an anthology of homogeneous and coherent destinations to make the Otherness more accessible for the readers. This process demonstrates how symbolic (re)productions of a territory can give rise to specific constructions of places creating different concepts of region and therefore performative spaces and opportunities of «agency». In other terms the (re)definition of the Sicilian territory proposed by the guide invites tourists to consider a new (narrated) geography invites and invites to interact with it thinking as visitors. From a geographical and cultural point of view reflection on these dynamics allows us to consider some (re)definitions of space in relation to forms of textualization (even on the maps). An imaginary but performative geography that attributes to the concept of territory epistemological and gnoseological possibilities.Settore M-GGR/01 - Geografia

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.
