On utilizing dependence-based information to enhance micro-aggregation for secure statistical databases

2011

Published version of an article in the journal: Pattern Analysis and Applications. Also available from the publisher at: http://dx.doi.org/10.1007/s10044-011-0199-9 We consider the micro-aggregation problem which involves partitioning a set of individual records in a micro-data file into a number of mutually exclusive and exhaustive groups. This problem, which seeks for the best partition of the micro-data file, is known to be NP-hard, and has been tackled using many heuristic solutions. In this paper, we would like to demonstrate that in the process of developing micro-aggregation techniques (MATs), it is expedient to incorporate information about the dependence between the random variable…

Sustainable production and consumption in remote working conditions due to COVID-19 lockdown in Italy: An environmental and user acceptance investiga…

2021

Abstract In response to the disruptive changes brought upon our society by the COVID-19 pandemic, most work activities and service providers had to resort to remote working. This is credited to reduce emissions for transportation, however the role of forced confinement within dwellings, especially if not designed for hosting working stations, deserves to be properly evaluated in terms of both user acceptance and long-term environmental impact. In this work, a dedicated survey campaign is used for investigating the potential pros and cons of remote working. In more detail, logistic regression and generalized linear models are used for capturing the effect of several independent variables on …

Convex functions on Carnot Groups

2007

We consider the definition and regularity properties of convex functions in Carnot groups. We show that various notions of convexity in the subelliptic setting that have appeared in the literature are equivalent. Our point of view is based on thinking of convex functions as subsolutions of homogeneous elliptic equations.

Exploring the Heterogeneity and Trajectories of Positive Functioning Variables, Emotional Distress, and Post-traumatic Growth During Strict Confineme…

2022

Abstract  COVID-19 pandemic-related confinement may be a fruitful opportunity to use individual resources to deal with it or experience psychological functioning changes. This study aimed to analyze the evolution of different psychological variables during the first coronavirus wave to identify the different psychological response clusters, as well as to keep a follow-up on the changes among these clusters. The sample included 459 Spanish residents (77.8% female, Mage = 35.21 years, SDage = 13.00). Participants completed several online self-reported questionnaires to assess positive functioning variables (MLQ, Steger et al. in J Loss Trauma 13(6):511–527, 2006. 10.1080/15325020802173660; GQ…

2021

ABSTRACT Background: The adverse consequences of the COVID-19 pandemic on mental health have been widely studied in recent months. However, few studies have examined the protective psychological factors that may explain how individuals are coping with the COVID-19 pandemic and its forced confinements. Objective: This study analyzes the impact of confinement due to the COVID-19 pandemic on positive functioning variables (resilience, meaning of life, gratitude, compassion, life satisfaction), emotional distress (depression, anxiety, perceived stress, affect), and posttraumatic growth (PTG). The impact was measured during and after the first month of strict and obligatory confinement in Spain.…

Coping strategies in older adults as a function of sociodemographic variables

2015

Para conseguir la adaptación a los cambios que se producen en el envejecimiento se ponen en marcha una serie de estrategias de afrontamiento. En este estudio, 275 adultos mayores, que acuden a un centro de mayores a realizar actividades, respondieron a una serie de datos sociodemográficos y al Cuestionario de Afrontamiento del Estrés (CAE) mediante una entrevista semiestructurada. El objetivo es analizar el uso de las estrategias de afrontamiento en función de diversas variables sociodemográficas, mediante el uso de correlaciones, pruebas t y ANOVAs. Los resultados mostraron una relación positiva y significativa entre la edad y la religión, y se observaron diferencias en función del género,…

Identifying predictive factors in compliance with the COVID-19 containment measures: A mediation analysis

2021

Giusy Danila Valenti, Palmira Faraci Faculty of Human and Social Sciences, University of Enna “Kore”, Enna, ItalyCorrespondence: Giusy Danila ValentiCittadella Universitaria, 94100, ItalyEmail giusy.valenti@unikore.itIntroduction: The outbreak of the COVID-19 pandemic has led governments to implement some containment measures to flatten the curve of the diffusion of the virus. The current study aims to investigate individual differences in compliance with these restrictive behaviors. In a sample of Italian individuals (N = 300), we examined whether sociodemographic factors, personality traits, fatalism, and fear could be considered as possible predictors.Methods: We performed a series o…

Psychological consequences of rheumatic diseases in children and adolescents: A first exploratory study

2009

The objective of our study was to make a first exploratory study about the psychological status of children and adolescents with rheumatic diseases exploring, also, the significant differences between girls and boys. A total of 123 children (81 girls and 42 boys) with rheumatic diseases, between the ages of 1 and 19 years old were assessed using different measures for evaluating behavioral and emotional problems. The results showed a picture of a mild or moderate degree of psychological problems in the different measures of anxiety, depression, general distress and behavioral problems. Girls, compared to boys, scored higher in most of the measures used, showing more internalizing than exter…
