Does the evidence matter in medicine? The retinoblastoma paradigm.
2007
Retinoblastoma (Rb) is the most common intraocular malignant tumour in childhood, with an incidence of 1 in 15,000 live births. Complete information on this rare tumour can be easily accessed through the internet, although many aspect concerning the aetiology and pathogenesis of the disease, are still controversial. The "two hit" theory, formulated in 1971 to explain the variegated clinical expression of the disease, is based on the idea that single gene mutation may determine the development of cancer. However, this view does not take into account the most recent evidences showing the role of aneuploidy and chromosome instability in cancer. Also, a number of other genes and epigenetic mech…
Does an intervention based on the pleasure of eating healthy foods could favour a positive relationship between food liking and perceived healthiness…
2019
International audience; It is generally admitted that consumers perceived unhealthy foods as tastier than healthy foods. However, the opposite association was found in French adults (Werle et al., 2013). Moreover, Marty et al. (2018) found that French children liked healthy foods as much as unhealthy foods. However, the link between liking and perceived healthiness in children needs to be further investigated, in particular at the individual level. Thus, our study aims, first at assessing the link between liking and perceived healthiness in children and, second at determining whether this potential link was modified after an intervention promoting pleasure of consuming healthy foods. To do …
Impact and Perspectives of American Bases in Italy
2009
Italy is expected to play a growing role in the American global strategy. The American military presence has recently provoked uneasiness in Italian society and growing protests, as a reflex of the weakening of the current global leader in terms of international legitimacy and political support. However, the acceptance of Italy''s role by governments of all shades is to be understood within the framework of the Euro-Atlantic pluralistic security community that still allows an improved environment in which it is easier to find co-operative solutions to problems as they arise, and to define common threats.
La mente del bambino: tra lungimiranza pedagogica ed evidenze neuroscientifiche. Uno studio comparato su Maria Montessori e la Brain-based Education
2021
Il paper intende tracciare una linea di congiunzione tra le intuizioni di Maria Montessori e le recenti evidenze neuroscientifiche: “La scoperta del bambino”, auspicata dalla studiosa all’inizio del XX secolo, è tuttora in corso e punta alla conquista della comprensione del funzionamento della mente del bambino. In particolare, la riflessione si sviluppa attorno ai seguenti temi: neuroplasticità neuronale e sinaptogenesi, lo sviluppo motorio, il processo attentivo e il meccanismo della mimesi. Questi argomenti, rinvigoriti dal dialogo tra la pedagogia montessoriana e le ricerche neuroscientifiche, possono determinare un nuovo modo di intendere la questione e la prassi educativa. The paper i…
Production technology of early-Hellenistic lime-based mortars from a Punic-Roman residential area at Palermo (Sicily)
2016
The topic of this study was the mineralogical and petrographic characterization of lime-based mortars of Hellenistic-Roman age (3rd century BC), taken from a residential area located in the historical centre of Palermo, near the walls of the Punic-Roman Neapolis, recently brought to light by excavations carried out by the Soprintendenza BB.CC.AA. of Palermo at Palazzo del Gran Cancelliere (Palermo). The collected mortars have been analyzed by optical microscopy (PLM), X-ray powder diffraction analysis (XRPD) and scanning electron microscopy coupled with energy dispersive spectrometry (SEM-EDS). The study was aimed to define the “recipe” (composition of temper and binder, temper size distrib…
Biopsychosocial Profiles of Patients With Cardiac Disease in Remote Rehabilitation Processes : Mixed Methods Grounded Theory Approach
2021
Background: Digital development has caused rehabilitation services and rehabilitees to become increasingly interested in using technology as a part of rehabilitation. This study was based on a previously published study that categorized 4 groups of patients with cardiac disease based on different experiences and attitudes toward technology (e-usage groups): feeling outsider, being uninterested, reflecting benefit, and enthusiastic using. Objective: This study identifies differences in the biopsychosocial profiles of patients with cardiac disease in e-usage groups and deepen the understanding of these profiles in cardiac rehabilitation. Methods: Focus group interviews and measurements were c…
Is There Hope for First Graders at the Lowest Percentiles? : The Roles of Self-Efficacy, Task Avoidance, and Support in the Development of Reading Fl…
2022
Self-efficacious children are expected to be more task-focused in challenging achievement situations and consequently have better chances of overcoming learning difficulties than children who have lower self-efficacy. The present study investigates this presumption with Finnish-speaking first graders struggling with reading acquisition ( N = 285). The development of the children’s reading fluency, self-efficacy, and task avoidance was followed from the middle of Grade 1 to the end of Grade 2, and a 6-week mobile game-based intervention was administered to those who exhibited the greatest risk for reading disabilities (≤ 5th percentile). Exploratory structural equation modeling was used to …
Violenze “di genere” e violenze “sulle donne”: problemi di definizione e di rilevazione empirica
2020
Il capitolo punta a problematizzare gli aspetti definitori del concetto di “violenza di genere” e quelli legati più strettamente alla sua rilevazione/misurazione, cercando di fornire un contributo all’utilizzo delle statistiche sul tema in maniera avveduta e consapevole. The chapter aims to problematize the defining aspects of the concept of "gender violence" and those related more closely to its detection / measurement, trying to provide a contribution to the use of statistics on the subject in a prudent and conscious manner.
Characterisation of component pigments in a mixture
2011
This work is part of Raman spectra database constitution of pigments and materials of Cultural Heritage interest for polychrome artworks characterization. The colours of paintings are often obtained mixing pigments of palette artist’s. The attribution of a work of art to an author and the individuation of fakes are related to the identification of used pigments and also to the detection of mixture constituents. The main research objective is the extension of PH3DRA laboratory database with information useful to detect not only each single pigment but also quantitative data regarding its relative ratio in the examined mixture. The availability of spectra as revealed represents the primary li…
Ecologists overestimate the importance of predictor variables in model averaging: a plea for cautious interpretations.
2014
Abstract: Information-theory procedures are powerful tools for multimodel inference and are now standard methods in ecology. When performing model averaging on a given set of models, the importance of a predictor variable is commonly estimated by summing the weights of models where the variable appears, the so-called sum of weights (SW). However, SWs have received little methodological attention and are frequently misinterpreted. We assessed the reliability of SW by performing model selection and averaging on simulated data sets including variables strongly and weakly correlated to the response variable and a variable unrelated to the response. Our aim was to investigate how useful SWs are …
