Development and validation of the social thermoregulation and risk avoidance questionnaire (STRAQ-1)
Attachment theory was built around the idea that infants rely on others to survive, and it is often forgotten that survival hinged on coping with environmental demands. Adult attachment reports have instead been organized around people’s subjective experience of safety and security in relationships. To resolve the gap between infant’s physical needs and adult attachment experiences, we made a first step by developing the Social Thermoregulation and Risk Avoidance Questionnaire (STRAQ-1) in 12 countries (N = 1510), providing a complementary measure to identify biological drives formative to attachment. We conjectured that co-regulatory patterns of temperature and stress are foundational to attachment styles and on this basis used a naïve bootstrapping method to find a robust solution, conducting seven exploratory factor analyses in an exploratory-confirmatory fashion. We identified 23 (out of 57) items in 4 subscales: Social Thermoregulation (Total Omega = .83), High Temperature Sensitivity (.83), Solitary Thermoregulation (.77), and Risk Avoidance (.57). In terms of external validity, we also found that the STRAQ-1 relates to emotion regulation strategies broadly and, importantly, relates to individual differences in attachment specifically, which in turn mediates the relationship with stress and health (making the scale face valid). Our approach provides a robust first effort in identifying biological mechanisms underlying attachment formation

Non-perturbative renormalization of the static axial current in two-flavour QCD
We perform the non-perturbative renormalization of matrix elements of the
static-light axial current by a computation of its scale dependence in lattice
QCD with two flavours of massless O(a) improved Wilson quarks. The
regularization independent factor that relates any running renormalized matrix
element of the axial current in the static effective theory to the
renormalization group invariant one is evaluated in the Schroedinger functional
scheme, where in this case we find a significant deviation of the
non-perturbative running from the perturbative prediction. An important
technical ingredient to improve the precision of the results consists in the
use of modified discretizations of the static quark action introduced earlier
by our collaboration. As an illustration how to apply the renormalization of
the static axial current presented here, we connect the bare matrix element of
the current to the B_s-meson decay constant in the static approximation for one
value of the lattice spacing, a ~ 0.08 fm, employing large-volume N_f=2 data at
beta=5.3.Comment: 33 pages including figures and tables, latex2e, uses JHEP3.cls;

Maturity-Onset Diabetes of the Young in Children With Incidental Hyperglycemia:: A multicenter Italian study of 172 families
OBJECTIVE - To investigate the prevalence of maturity-onset diabetes of the young (MODY) in Italian children With incidental hyperglycemia. RESEARCH DESIGN AND METHODS - Among 748 subjects age 1-18 years with incidental hyperglycemia, minimal diagnostic criteria for MODY were met by 172 families. Mutational analyses of the glucokinase (GCK) and hepatocyte nuclear factor lot (HNF1A) genes were performed. RESULTS - We identified 85 GCK gene mutations in 109 probands and 10 HNF1A mutations in 12 probands. In GCK patients, the median neonatal weight and age at the first evaluation were lower than those found in patients with HNF1A mutations. Median fasting plasma glucose and impaired fasting glucose/impaired glucose tolerance frequency after oral glucose tolerance testing were higher in GCK patients, who also showed a lower frequency of diabetes than HNF1A patients. CONCLUSIONS - GCK mutations are the prevailing cause of MODY (63.4%) when the index case is recruited in Italian children with incidental hyperglycemia
Birth and Death in a Continuous Opinion Dynamics Model. The consensus case
We here discuss the process of opinion formation in an open community where
agents are made to interact and consequently update their beliefs. New actors
(birth) are assumed to replace individuals that abandon the community (deaths).
This dynamics is simulated in the framework of a simplified model that accounts
for mutual affinity between agents. A rich phenomenology is presented and
discussed with reference to the original (closed group) setting. Numerical
findings are supported by analytical calculations.Comment: 13 pages, 6 figure
The continuum limit of the static-light meson spectrum
We investigate the continuum limit of the low lying static-light meson
spectrum using Wilson twisted mass lattice QCD with N_f = 2 dynamical quark
flavours. We consider three values of the lattice spacing a ~ 0.051 fm, 0.064
fm, 0.080 fm and various values of the pion mass in the range 280 MeV < m_PS <
640 MeV. We present results in the continuum limit for light cloud angular
momentum j = 1/2, 3/2, 5/2 and for parity P = +, -. We extrapolate our results
to physical quark masses, make predictions regarding the spectrum of B and B_s
mesons and compare with available experimental results.Comment: 18 pages, 3 figure
Contextual influences on italian university students during the covid-19 lockdown: Emotional responses, coping strategies and resilience
none17Based on an ecological perspective on the COVID-19 lockdown experience, this study describes psychological responses among Italian university students. Our study considers three zones of the country that have differed in the intensity of the COVID-19 pandemic. Specifically, this research explores whether differences in pandemic conditions can account for their divergent psychological outcomes. The participants were 792 university students from seven different Italian universities. Students were asked to express their emotions and describe meaningful events during the lockdown in writing. Based on the grounded theory approach, this study conducted qualitative data analysis using ATLAS.ti 8.0. The core emerged categories are emotions, emotional moods and state of mind, coping strategies, and resilience. The results describing these emergent factors in relation to environmental variables highlight differences in the feeling of anxiety among individuals: anxiety was more self-focused in zones that were more affected by the lockdown, while such anxiety was more related to family and friends in less-affected zones. In addition to identifying the negative repercussions that this emergency has had, this study describes some positive outcomes, such as the elaboration of new personal perspectives that help foster individual growth and allow individuals to gain new awareness of themselves and others. The confinement due to the COVID-19 emergency measures has been a very unique experience for people, and further research is needed to understand the long-term effects of the different coping responses activated by participants during and after the lockdown.mixedLaura Migliorini; Norma De Piccoli; Paola Cardinali; Chiara Rollero; Daniela Marzana; Caterina Arcidiacono; Elisa Guidi; Ciro Esposito; Cinzia Novara; Angela Fedi; Elena Marta; Andrea Guazzini; Patrizia Meringolo; Maria Grazia Monaci; Barbara Agueli; Fortuna Procentese; Immacolata Di NapoliMigliorini, Laura; De Piccoli, Norma; Cardinali, Paola; Rollero, Chiara; Marzana, Daniela; Arcidiacono, Caterina; Guidi, Elisa; Esposito, Ciro; Novara, Cinzia; Fedi, Angela; Marta, Elena; Guazzini, Andrea; Meringolo, Patrizia; Grazia Monaci, Maria; Agueli, Barbara; Procentese, Fortuna; Di Napoli, Immacolat
