β and γ bands in N = 88, 90, and 92 isotones investigated with a five-dimensional collective Hamiltonian based on covariant density functional theory…
2019
A comprehensive systematic study is made for the collective β and γ bands in even-even isotopes with neutron numbers N=88 to 92 and proton numbers Z=62(Sm) to 70 (Yb). Data, including excitation energies, B(E0) and B(E2) values, and branching ratios from previously published experiments are collated with new data presented for the first time in this study. The experimental data are compared to calculations using a five-dimensional collective Hamiltonian (5DCH) based on the covariant density functional theory (CDFT). A realistic potential in the quadrupole shape parameters V(β,γ) is determined from potential energy surfaces (PES) calculated using the CDFT. The parameters of the 5DCH are fixe…
Comparative analysis of muon-capture and 0νββ-decay matrix elements
2020
Average matrix elements of ordinary muon capture (OMC) to the intermediate nuclei of neutrinoless double beta (0νββ) decays of current experimental interest are computed and compared with the corresponding energy and multipole decompositions of 0νββ-decay nuclear matrix elements (NMEs). The present OMC computations are performed using the Morita-Fujii formalism by extending the original formalism beyond the leading order. The 0νββ NMEs include the appropriate short-range correlations, nuclear form factors, and higher-order nucleonic weak currents. The nuclear wave functions are obtained in extended no-core single-particle model spaces using the spherical version of the proton-neutron quasip…
Gas phase behavior of radical cations of perfluoroalkyl-1,2,4-triazines: an experimental and theoretical study
2009
Electron ionization mass spectrometry and low-energy collision-induced decomposition reactions occurring in a tridimensional ion trap, together with density functional theory (DFT) calculations on neutrals, even- and odd-electron cations, have been used to study the gas-phase ion chemistry of a series of perfluoroalkyl-1,2,4-triazines. Loss of oxygen, due to thermal degradation occurring before ionization, likely involving the hydroxylamino group, has been observed. Compounds having a carbonyl group at position 6 of the triazine ring fragment in the source by elimination of NO followed by HF or CO. The decomposition pathways occurring due to CID experiments have shown interesting features d…
Lo zerosei di fronte all’emergenza COVID. Esperienze, ricerche e riflessioni pedagogiche
2022
Il volume prende le mosse da un incontro on line organizzato il 28 novembre 2020 dal Gruppo SIPED Infanzia sul tema: Lo zero-sei di fronte all’emergenza COVID. In quella sede vennero proposte riflessioni particolarmente interessanti, che hanno trovato poi un approfondimento scientifico nei diversi contributi raccolti. È suddiviso in tre parti tra loro interrelate, che spaziano temporalmente dall’improvvisa chiusura totale dei servizi per l’infanzia a marzo 2020, fino alle prime esperienze di riapertura in nuovi assetti organizzativi nell’a.s. 2020-21. La situazione pandemica e le sue conseguenze pratiche, hanno generato criticità gestionali, oltre a preoccupazione e disorientamento nel pers…
Deconstructing and reconstructing resilience: a dynamic network approach
2019
Resilience is still often viewed as a unitary personality construct that, as a kind of anti-nosological entity, protects individuals against stress-related mental problems. However, increasing evidence indicates that the maintenance of mental health in the face of adversity results from complex and dynamic processes of adaptation to stressors that involve the activation of several separable protective factors. Such resilience factors can reside at biological, psychological and social levels and may include stable predispositions (such as genotype or personality traits) and malleable properties, skills, capacities or external circumstances (such as gene expression patterns, emotion regulatio…
Predictores emocionales y de personalidad que infl uyen en la aparición de las quejas somáticas en niños y en adultos
2019
Personality and emotional factors may be contributing to the emergence of somatic complaints. The purpose of this study was to analyse the combined contribution of emotional awareness, moods and personality to somatic complaints in children and adults. Method: Participants were 1,476 children (M= 9.90 years, SD= 1.27, 52.10% girls) and 940 adults (M= 32.30 years, SD= 11.62, 64% women) who were administered self-reports. Analysis was performed using fuzzy qualitative comparative analysis (fsQCA), an analytical technique that enables in-depth analysis of how a series of causal conditions contribute to a given outcome. Results: Emotional awareness, moods and personality account for 59% of high…
Theoretical review of emotional intelligence: models and measuring instruments
2013
Abstract This theoretical review of emotional intelligence (EI) starts from the earliest conceptualizations made by Galton, Binet, Stemberg Thurstone and Thordinke Gardner, who, during their historical period, were successful in laying the basis for the birth of emotional intelligence as a theoretical construction which was introduced for the first time, in scientific literature, in 90’s. Since then, different EI models have been developed and investigative contributions have been increased. In this article, the most representative EI models will be described with details, such as: 1) Mental ability model (Ability Based) developed by Mayer and Salovey 2) Model of emotional competences by Go…
ENAZIONE, MODELLI MENTALI E POLITICA LINGUISTICA FASCISTA E FRANCHISTA
2021
The main objective of the article is to analyze, thanks to the application of the enactive approach and that of the mental models of van Dijk, the way in which the fascist and franquist linguistic policy was articulated through the analysis of some significant articles present in the bilingual magazine «Legioni e Falan- gi. Rivista d’Italia e di Spagna/Legiones y Falanges. Revista mensual de Italia y de España». In fact, this magazine is one of the many examples of public expression of a regime’s will to control, exercised through the use of a firm and full of ideology language used to establish control in order to influence the reader’s behaviors. The final considerations reached in the ar…
Human interleukin-6 facilitates hepatitis B virus infection in vitro and in vivo.
2000
Abstract Background and aim. Research on hepatitis B virus (HBV) infection in vivo has been limited due to the absence of a suitable animal model. We have developed a human–mouse radiation chimera in which normal mice, preconditioned by lethal total body irradiation and radioprotected with SCID mouse bone marrow cells, are permissive for engraftment of human hematopoietic cells and solid tissues. This resulting human–mouse model, which comprises three genetically disparate sources of tissue, is therefore termed Trimera. This study was aimed at assessing the effect of human IL-6 on HBV infection in vivo in Trimera mice. Methods. Trimera mice were transplanted with human liver tissue fragment…
Autoimmune thyroid disease: new models of cell death in autoimmunity
2002
Autoimmunity to thyroid antigens leads to two distinct pathogenic processes with opposing clinical outcomes: hypothyroidism in Hashimoto's thyroiditis and hyperthyroidism in Graves' disease. The high frequency of these diseases and easy accessibility of the thyroid gland has allowed the identification of key pathogenic mechanisms in organ-specific autoimmune diseases. In early investigations, antibody- and T-cell-mediated death mechanisms were proposed as being responsible for autoimmune thyrocyte depletion. Later, studies on apoptosis have provided new insights into autoimmune target destruction, indicating the involvement of death receptors and cytokine-regulated apoptotic pathways in the…
