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…
The impact of strict and forced confinement due to the COVID-19 pandemic on positive functioning variables, emotional distress, and posttraumatic gro…
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 âKoreâ, 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…
Corporate governance and firm performance: A comparative analysis of auditing problems
2006
The recent financial crises have created a new debate about comparison and convergence of different systems of corporate governance. In particular, they have underlined poor efficiency of rule structures to achieve a good relationship between different stakeholder’s rights. In line with many studies of corporate governance that emphasize the manager-stakeholders relationship as explained by agency theory, in this paper, I analyse the role of auditing as an incentive device to reduce contractual or transaction costs related to asymmetric information.Considering as a benchmark the recent US Sarbanes Oxley Act of July 2002. I describe a set of auditing principles by comparing common and civil …
Fluctuation-dissipation relations for Markov processes.
2005
The fluctuation-dissipation relation is calculated for stochastic models obeying a master equation with continuous time. In the general case of a nonstationary process, there appears to be no simple relation between the response and the correlation. Also, if one considers stationary processes, the linear response cannot be expressed via time-derivatives of the correlation function alone. In this case, an additional function, which has rarely been discussed previously, is required. This so-called asymmetry depends on the two times also relevant for the response and the correlation and it vanishes under equilibrium conditions. The asymmetry can be expressed in terms of the propagators and the…

Similarity Solutions and Collapse in the Attractive Gross-Pitaevskii Equation
2000
We analyse a generalised Gross-Pitaevskii equation involving a paraboloidal trap potential in $D$ space dimensions and generalised to a nonlinearity of order $2n+1$. For {\em attractive} coupling constants collapse of the particle density occurs for $Dn\ge 2$ and typically to a $\delta$-function centered at the origin of the trap. By introducing a new dynamical variable for the spherically symmetric solutions we show that all such solutions are self-similar close to the center of the trap. Exact self-similar solutions occur if, and only if, $Dn=2$, and for this case of $Dn=2$ we exhibit an exact but rather special D=1 analytical self-similar solution collapsing to a $\delta$-function which …
Variable kinematics models and finite elements for nonlinear analysis of multilayered smart plates
2015
Abstract A variable kinematics approach for moderately large deflection analysis of smart magneto-electro-elastic multilayered plates is presented. The approach is based on the condensation of the electro-magnetic state into the plate kinematics, whose nonlinear strain–displacement relationships are expressed in the von Karman sense. This leads to models resulting in an effective mechanical plate, which takes the multifield coupling effects into account by the plate stiffness, inertia and loading characteristics, consistently defined as combinations of the layers material properties. By a unified approach, both equivalent single layer and layerwise models are developed formulating the assoc…
