Abilità di apprendimento di lettura e scrittura in bambini in età prescolare e predittori di rischio
2014
The years from birth through age 5 are a critical time for children’s development and learning. Early childhood educators understand that at home and in early childhood education settings, young children learn important skills that can provide them with the cornerstones needed for the development of later academic skills. These patterns of learning in preschool are closely linked to later achievement: children who develop more skills in the preschool years perform better in the primary grades. The development of early skills appears to be particularly important in the area of literacy. It is estimated that more than a third of all graders (and an even higher percentage of our at-risk studen…
Palermo-2010 conference on biogerontology
2011
We, as the guest editors, are pleased to introduce this special issue of Biogerontology, which is the outcome from the 7th European Congress of Biogerontology, held from 14th to 17th October, 2010 in Palermo, Italy. The thematic aim of the Palermo-conference was to get an overview of the present state of research in the development of effective therapies to postpone or treat human ageing, focusing on predictive medicine and prevention of age-related diseases, immunosenescence, longevity, model systems, ageing and wellness, and vaccination in the elderly. Understanding the determinants of ageing in humans in relation to the living environment and the individual life history was the additiona…
Distribution, function and predictive value of tumor-infiltrating γδ T lymphocytes
2013
Although γδ T cells are known to exert both tumor-preventing and tumor-promoting activity, there is still little information on the functional characteristics and clinical significance of γδ T cells isolated from the tumor site. In a recent study, we have investigated the distribution of different γδ T-cell populations in melanoma and their impact on disease outcome.
Profiling the risk of hepatocellular carcinoma after long-term HCV eradication in patients with liver cirrhosis in the PITER cohort
2023
Background and aims: Severe liver disease markers assessed before HCV eradication are acknowledged to usually improve after the SVR. We prospectively evaluated, in the PITER cohort, the long-term HCC risk profile based on predictors monitored after HCV eradication by direct-acting antivirals in patients with cirrhosis. Methods: HCC occurrence was evaluated by Kaplan-Meier analysis. Cox regression analysis identified the post-treatment variables associated with de-novo HCC; their predictive power was presented in a nomogram. Results: After the end of therapy (median follow-up:28.47 months), among 2064 SVR patients, 119 (5.8%) developed de-novo HCC. The HCC incidence was 1.90%, 4.21%, 6.47% a…
Semiparametric estimation of conditional intensity functions for space-time processes
2008
When dealing with data coming from a space time inhomogeneous process, there is often the need of obtaining reliable estimates of the conditional intensity function. According to the field of application, intensity function can be estimated through some assessed parametric model, where parameters are estimated by Maximum Likelihood method. If we are only in an exploratory context or we would like to assess the adequacy of the parametric model, some kind of nonparametric estimation is required. Often, isotropic or anisotropic kernel estimates can be used, e.g. using the Silverman rule for the choice of the windows sizes h (Silverman, 1986). When the purpose of the study is the estimation of …

Weighted-Average Least Squares (WALS): Confidence and Prediction Intervals
2022
We extend the results of De Luca et al. (2021) to inference for linear regression models based on weighted-average least squares (WALS), a frequentist model averaging approach with a Bayesian flavor. We concentrate on inference about a single focus parameter, interpreted as the causal effect of a policy or intervention, in the presence of a potentially large number of auxiliary parameters representing the nuisance component of the model. In our Monte Carlo simulations we compare the performance of WALS with that of several competing estimators, including the unrestricted least-squares estimator (with all auxiliary regressors) and the restricted least-squares estimator (with no auxiliary reg…
Values that Underlie and Undermine Well–Being: Variability across Countries
2017
We examined relations of 10 personal values to life satisfaction (LS) and depressive affect (DEP) in representative samples from 32/25 countries ( N = 121 495). We tested hypotheses both for direct relations and cross–level moderation of relations by Cultural Egalitarianism. We based hypotheses on the growth versus self–protection orientation and person–focus versus social–focus motivations that underlie values. As predicted, openness to change values (growth/person) correlated positively with subjective well–being (SWB: higher LS, lower DEP) and conservation values (self–protection/social) correlated negatively with SWB. The combination of underlying motivations also explained more comple…
Assessing hot and cool executive functions in preschoolers: affective flexibility predicts emotion regulation
2018
Affective flexibility (AF) is the ability to alternate between processing emotional and non-emotional information. This hot executive function has been understudied during early development. The fi...
Predictive value of the Merrill-Palmer-R Scale applied during the first year of live
2016
Resumen basado en el de la publicación Títulos, resumen y palabras clave en inglés y español El valor predictivo de una escala de desarrollo utilizado durante el primer año de vida es de gran interés en la planificación de las intervenciones tempranas. El valor predictivo de un instrumento es la probabilidad de acertar el diagnóstico de trastorno o retraso en el desarrollo de un niño. Se analizaron las puntuaciones de escala Merrill-Palmer-R (MP-R) en una muestra de 291 niños menores de un año de la Comunidad Valenciana. A pesar de que no se distribuyen normalmente las puntuaciones de la escala MP-R en esta muestra, los resultados predichos eran buenos. Además, las puntuaciones de desarroll…
