RELIGIOSITY AND SCHOOL INTEGRATION AMONG ITALIAN AND NON-ITALIAN STUDENTS. RESULTS FROM A SURVEY IN MULTI-ETHNIC CLASSROOMS
The paper investigates the role of religion among a group of adolescents (11-15-year-old) surveyed in Italian multicultural schools. The multicultural classrooms (with over 30% of pupils with ethnic background) may be interpreted as social spaces for inter-ethnic coexistence, open to ethnic and religious diversity. We rely on a sample of 1,040 students enrolled in lower secondary education in Lombardy in 2011 on which we investigate religiosity, conceptualized as consisting of religious belonging and religious practice. The investigation questions are: does religiosity hamper horizontal relationships with classmates and vertical relationships with teachers? What consequence does the religious practice produce on educational achievement, and more in general on school integration? On average, religious students tend to report a higher level of integration (positive relationships with peers/teachers) compared to non-religious students, even after controlling for a wide set of covariates. In addition, they gain higher marks. Furthermore, these positive results are similar among Italian and non-Italian students: for future research, this evidence suggests that religiosity of students with an immigrant background could be considered as a resource for their educational integration, especially when schools are more welcoming towards religious diversity
NURE: An ERC project to study nuclear reactions for neutrinoless double beta decay
Neutrinoless double beta decay (0νββ) is considered the best potential resource to
access the absolute neutrino mass scale. Moreover, if observed, it will signal that neutrinos are
their own anti-particles (Majorana particles). Presently, this physics case is one of the most
important research âbeyond Standard Modelâ and might guide the way towards a Grand
Unified Theory of fundamental interactions.
Since the 0νββ decay process involves nuclei, its analysis necessarily implies nuclear structure
issues. In the NURE project, supported by a Starting Grant of the European Research Council
(ERC), nuclear reactions of double charge-exchange (DCE) are used as a tool to extract
information on the 0νββ Nuclear Matrix Elements. In DCE reactions and ββ decay indeed the
initial and final nuclear states are the same and the transition operators have similar structure.
Thus the measurement of the DCE absolute cross-sections can give crucial information on ββ
matrix elements. In a wider view, the NUMEN international collaboration plans a major
upgrade of the INFN-LNS facilities in the next years in order to increase the experimental
production of nuclei of at least two orders of magnitude, thus making feasible a systematic
study of all the cases of interest as candidates for 0νββ
Defining Kawasaki disease and pediatric inflammatory multisystem syndrome-temporally associated to SARS-CoV-2 infection during SARS-CoV-2 epidemic in Italy: results from a national, multicenter survey
Background: There is mounting evidence on the existence of a Pediatric Inflammatory Multisystem Syndrome-temporally associated to SARS-CoV-2 infection (PIMS-TS), sharing similarities with Kawasaki Disease (KD). The main outcome of the study were to better characterize the clinical features and the treatment response of PIMS-TS and to explore its relationship with KD determining whether KD and PIMS are two distinct entities.
Methods: The Rheumatology Study Group of the Italian Pediatric Society launched a survey to enroll patients diagnosed with KD (Kawasaki Disease Group - KDG) or KD-like (Kawacovid Group - KCG) disease between February 1st 2020, and May 31st 2020. Demographic, clinical, laboratory data, treatment information, and patients' outcome were collected in an online anonymized database (RedCAPÂŽ). Relationship between clinical presentation and SARS-CoV-2 infection was also taken into account. Moreover, clinical characteristics of KDG during SARS-CoV-2 epidemic (KDG-CoV2) were compared to Kawasaki Disease patients (KDG-Historical) seen in three different Italian tertiary pediatric hospitals (Institute for Maternal and Child Health, IRCCS "Burlo Garofolo", Trieste; AOU Meyer, Florence; IRCCS Istituto Giannina Gaslini, Genoa) from January 1st 2000 to December 31st 2019. Chi square test or exact Fisher test and non-parametric Wilcoxon Mann-Whitney test were used to study differences between two groups.
Results: One-hundred-forty-nine cases were enrolled, (96 KDG and 53 KCG). KCG children were significantly older and presented more frequently from gastrointestinal and respiratory involvement. Cardiac involvement was more common in KCG, with 60,4% of patients with myocarditis. 37,8% of patients among KCG presented hypotension/non-cardiogenic shock. Coronary artery abnormalities (CAA) were more common in the KDG. The risk of ICU admission were higher in KCG. Lymphopenia, higher CRP levels, elevated ferritin and troponin-T characterized KCG. KDG received more frequently immunoglobulins (IVIG) and acetylsalicylic acid (ASA) (81,3% vs 66%; p = 0.04 and 71,9% vs 43,4%; p = 0.001 respectively) as KCG more often received glucocorticoids (56,6% vs 14,6%; p < 0.0001). SARS-CoV-2 assay more often resulted positive in KCG than in KDG (75,5% vs 20%; p < 0.0001). Short-term follow data showed minor complications. Comparing KDG with a KD-Historical Italian cohort (598 patients), no statistical difference was found in terms of clinical manifestations and laboratory data.
Conclusion: Our study suggests that SARS-CoV-2 infection might determine two distinct inflammatory diseases in children: KD and PIMS-TS. Older age at onset and clinical peculiarities like the occurrence of myocarditis characterize this multi-inflammatory syndrome. Our patients had an optimal response to treatments and a good outcome, with few complications and no deaths
The Muon Portal Project: construction and preliminary tests of the detection modules
In the last years, the demand for increasing the control security at borders and ports has lead to the development of innovative and reliable techniques to inspect the contents of traveling containers.
Traditional systems based on X-ray inspection cannot be employed on occupied vehicles, since the energy or dose required would be too high in order to penetrate big cargos.One of the most promising technique is the so-called muon tomography: by measuring the deflection suffered by cosmic muons when traversing high-Z materials, it is possible to reconstruct a 3D image of the volume to be inspected and detect the presence of fissile (U, Pu) samples in a reasonable amount of time (a few minutes).
The Muon Portal is a recently started Project aiming at the construction of a large area tracking detector that exploits the muon tomography technique to inspect the contents of traveling cargo containers.
The detection setup is based on eight position-sensitive planes (giving X- and Y-coordinates).
Each detection planes are segmented into strips of extruded plastic scintillators with wavelength-shifting (WLS) fibres to transport the light produced in the scintillator material to the photo-sensors at one of the fibre ends.
In this Thesis the relevance of the muon tomography technique, the design of the Muon Portal Project, the characterization of scintillator strips, WLS fibers and SiPM devices for the detection modules are discussed.
Some preliminary results on the tests of the first detection modules, the current installation status and a possible use of the Muon Portal detector in cosmic ray physics are also presented
Lezioni dal Covid-19: il lavoro degli insegnanti tra autonomia estrema e nuove collegialitĂ
Due to the unexpected pandemic crisis, teachers were forced to face the challenges imposed by social distancing. Within a few weeks of the national closure of the schools, Distance Learning (DL) was activated to guarantee school service continuity. The article reconstructs â through qualitative empirical material â how teachers handled DL and how they defined its heterogeneous forms in each school. In this article, it is shown how the sudden translation of school into the digital world took place. We focus on the interplay of teachersâ autonomy and collegiality, trying to throw light on how heterogeneous solutions to the pandemic, based on remote working, emerged within Italian schools

The NUMEN project @ LNS : Status and perspectives
The aim of the NUMEN project is to access the Nuclear Matrix Elements (NME), involved in the half life of the neutrinoless double beta decay (0νββ), by measuring the cross sections of Heavy Ions (HI) induced Double Charge Exchange (DCE) reactions with high accuracy. First evidence of the possibility to get quantitative information about NME from experiments is shown in the reaction 40Ca(18O,18Ne)40Ar at 270 MeV, performed with MAGNEX spectrometer using Superconducting Cyclotron (CS) beams at INFN - Laboratory Nazionali del Sud (LNS) in Catania. Preliminary tests on 116Sn and 116Cd target are already performed. High beam intensity is the new frontiers for these studies.peerReviewe
