L’uso del WHOQOL-BREF e dello EUROP-ASI nell’assessment dei disturbi da uso di sostanze: un’indagine comparativa
2010
Lo scopo del presente contributo è rintracciare, attraverso alcuni dati di ricerca, l’esistenza di correlazioni significative tra i punteggi compositi delle diverse aree dello EuropASI e le sezioni della forma breve del WHOQOL in pazienti con disturbo da uso di sostanze, con l’obiettivo di osservare le relazioni esistenti tra l’autovalutazione del benessere soggettivo e la valutazione degli operatori sulla gravità dei problemi connessi alla dipendenza da sostanze. La ricerca ha coinvolto un gruppo di 30 pazienti afferenti ad un Ser.T. del Distretto 13 della AUSL 6 di Palermo. I pazienti sono stati selezionati random, secondo i seguenti criteri di inclusione: diagnosi di dipendenza da sostan…
A wavelet Methodology for EEG Time-frequency Analysis in a Time Discrimination Task
2009
EEG signals recorded by surface electrodes placed on the scalp can be thought as non- stationary stochastic processes in both time and space, especially in response to external stimuli. Cognitive tasks, in particular, are reflected by changes in EEG dynamics concerning both rhythms energy and connectivity across different brain regions. In the frequency-domain, EEG analysis is complicated and time-frequency methodologies are needed. The Wavelet Transform, in particular, represents a powerful tool for analysing, within a time-frequency embedding, the EEG. In this study we applied a wavelet-based methodology to extract quantitative time-frequency parameters from EEG signals recorded during a …
Il linguaggio della rete. Il Modello delle Categorie Linguistiche e i contesti del Web 2.0
2014
Obiettivo del presente contributo è stato di analizzare gli stili comunicativi all'interno dei nuovi contesti del Web 2.0, mediante l'utilizzo del Modello delle categorie linguistiche. I risultati hanno evidenziato come strumenti diversi (blog, Facebook, Twitter) orientino e condizionino la comunicazione in modo differente, ed inoltre come il grado di astrazione linguistica sia scarsamente in relazione con la capacità di generare repliche e condivisioni per ogni messaggio.
ONLINE SOCIAL COMPARISON ITS ROLE IN PREDICTING INDIVIDUALS’ WELL-BEING
2023
Social comparison is the practice through which people compare their own opinions, abilities, behaviours, and emotions with those of others as an external guide and a source for self-evaluation. Social comparison has been put forward as a core feature of interpersonal relationships both in the offline context and in virtual interactions through social media. A growing number of studies has highlighted that online social comparison through social media can influence individuals’ everyday life. In this thesis, I will examine the role of online social comparison in influencing individuals’ well-being in three research designs with different outcomes. In the first empirical study, a cross-lagge…
Well-being of physicians who work in oncology unit and in BMT unit: analysis of protective factors from work stress
2012
Background. Recently a great deal of attention has been given on doctors' work related stress and possibility of improving their quality of life. Several studies report that oncologists are overloaded psychologically. Contact with serious diseases, excessive working pressure, structural weaknesses, are some of the factors that predispose oncologists to stress. In 2008, at the ASPHO annual meeting, pediatric hematologists/oncologists noted burnout (considered as a result of protracted stress at work) was a significant challenge in their lives. To date, no studies have extensively ruled out on protective factors from work stress among pediatric oncologists. Aims. Our research investigates the…
The impact of adult attachment style on organizational commitment and adult attachment in the workplace
2015
International audience; Adult attachment style has only recently been considered as having a role in explaining work behavior. The present research aimed to explore the impact of adult attachment style, assessed by the Adult Attachment Interview (AAI), on organizational commitment (OC) and on adult attachment in the workplace (AAW). We hypothesized that a secure attachment style would be positively related to affective and normative commitment, while preoccupied and avoidant styles would be negatively related to affective commitment; we also hypothesized that there would be a correspondence between the AAI categories and the AAW dimensions. Using the AAI categories as group variable, analys…
The need for recovery scale
2013
Abstract Introduction Need for Recovery scale is one of the main scales used to assess work-induced fatigue and quality of workers’ recovery time. In fact, need for recovery is considered relevant as a precursor of prolonged fatigue or psychological distress, an indicator of work stress, and a mediating or moderating characteristic in the etiology of work-related health problems, sick leave and work disability. Objective The purpose of the present study is to translate the Need for Recovery scale into Italian, and to adapt it to Italian culture; until now there has been no comparable valid instrument made for the Italian language that measures the need for recovery of employees. The stabili…

Organizational Performance Dynamics : a preliminary model
2023
The main objective of this model (an Interactive Learning Environment) is to help the reader understand how employees' motivational dynamics influence organizational performance. The model will allow you, through an iterative learning process, to understand: - the feedback structure of dynamic organizational performance system - the main motivational variables that influence the organizational performance - the organizational levers able to affect the employees' motivational dynamics The model will allow the reader to figure out the complex relationship between employee motivation and organizational performance through an "experimental" approach, using the simulation features provided by th…
