Science, Its Publics and New Media. Reflecting on the Present and Future of Science Communication.
2013
Scientific journalism faces the challenge to adapt not only to new formats but also to new information exchange dynamics. New online platforms, making it easier to access and produce scientific content, are forcing science publics to evolve. The online environment has turned into science communication reality, and both scientists and communicators must adapt to it. This paper discusses these changes and their implications for science journalism and an informed citizenry.
In-beam test results of the Super-FRS GEM-TPC detector prototype with relativistic uranium ion beam
2023
As an essential part of the Super-FRS particle identification, the GEM-TPC detector in a twin field-cage configuration will provide position information at up to 1 MHz counting rate with a spatial resolution 95 %. This detector is designed to provide particle-beam tracking information of projectiles ranging from protons to uranium. The performance of the GEM-TPC detector in a single field-cage configuration and newly integrated AWAGS readout electronics with a differential output was studied at the FRS for the response to the uranium beam at 850 MeV/u with intensity up to 1000 ions/spill. The result shows that a clusterization algorithm developed for this analysis works properly. The spatia…
Behavioral Restriction Determines Left Attentional Bias: Preliminary Evidences From COVID-19 Lockdown
2021
International audience; During the COVID-19 lockdown, individuals were forced to remain at home, hence severely limiting the interaction within environmental stimuli, reducing the cognitive load placed on spatial competences. The effects of the behavioral restriction on cognition have been little examined. The present study is aimed at analyzing the effects of lockdown on executive function prominently involved in adapting behavior to new environmental demands. We analyze non-verbal fluency abilities, as indirectly providing a measure of cognitive flexibility to react to spatial changes. Sixteen students (mean age 20.75; SD 1.34), evaluated before the start of the lockdown (T1) in a battery…

Spettrofotometria per il monitoraggio degli interventi di restauro: valutazione tramite PCA
2011
La realizzazione di indagini spettrofotometriche per il monitoraggio delle variazioni cromatiche pone la necessità di gestire un elevato numero di dati richiedendo l’utilizzo di analisi statistiche. A tale scopo, la PCA è stata applicata a dati spettrofotometrici relativi a diverse tipologie di superfici (musive, marmoree, etc). Tale metodologia permette di valutare in maniera efficace gli effetti generati a seguito del restau;ro, evidenziando la correlazione tra tutte variabili spettrofotometriche. La distribuzione in cluster dei dati consente di visualizzare la variabile che maggiormente contribuisce allo spostamento cromatico, permettendo il monitoraggio differenziato del comportamento d…
L'exclusion des ministres communistes du gouvernement en mai 1947
2022
Le 4 mai 1947, les ministres communistes sont exclus du gouvernement, auquel ils participaient depuis la Libération. Dans un contexte de conflictualité sociale et d'exacerbation des tensions géopolitiques, à l'aube de la guerre froide, l'alliance tripartite entre le PCF, la SFIO et le MRP semblait vouée à la rupture. Celle-ci n'était toutefois pas pensée comme définitive par les communistes en mai 1947, de telle sorte que l'on peut distinguer deux dynamiques qui participent successivement au processus d'isolement des communistes : une « exclusion positive » de ces derniers par le reste du gouvernement dans un premier temps, avec la conviction de pouvoir y revenir rapidement, puis un phénomè…
Una aproximación a las concepciones de estudiantes preuniversitarios y universitarios sobre pilas galvánicas
2014
En el presente trabajo se han investigado las concepciones alternativas sobre pilas galvánicas y las interpretaciones de los procesos que tienen lugar en una pila voltaica simple. Han participado en él 55 estudiantes del 2º de Bachillerato español (curso previo al ingreso en la universidad) y 43 estudiantes de primer año del Grado de Química. El análisis comparativo de los resultados de la administración de un test y de una pregunta abierta revela que: a) Tanto los estudiantes de 2º de bachillerato como los de 1º de Grado sostienen concepciones erróneas sobre pilas galvánicas; b) No hay diferencias significativas en las concepciones e interpretaciones entre ambos grupos de estudiantes, y c)…
The new version of the pictorial scale of Perceived Movement Skill Competence in Spanish children: Evidence of validity and reliability. [La nueva ve…
2019
The purpose of this study was to i) examine reliability and construct validity of the pictorial scale of Perceived Movement Skill Competence (PMSC) aligned to the third version of the Test of Gross Motor Development (TGMD-3) in a sample of Spanish children; and to ii) analyse the validity of the PMSC and children’s perceived motor competence (MC) according to gender. A convenience sample of 361 children (55.7% boys) between 4 and 11 years-old participated. The pictorial scale of PMSC (19 items) was administered (a random subsample repeated the PMSC twice). Test-retest reliability using Intraclass Correlation Coefficients and construct validity using a Bayesian Structural Equation Modeling a…
Femoral Versus Radial Artery Access for CTO PCIs: Is This the Final Round?
2022
Historically, cardiac catheterization has been performed via transfemoral access (TFA). Although TFA remains necessary in multiple diagnostic and interventional settings, this technique has been associated with vascular access site complication rates ranging from 2% to 6%, prolonged hospital stay, and more deaths compared with radial artery access. Furthermore, safe utilization of the femoral artery can be compromised by abdominal obesity, atherosclerosis at the puncture site, and antithrombotic therapy, all which increase the bleeding risk.1 In the last decade, transradial artery access (TRA) emerged as the recommended approach for percutaneous coronary interventions (PCI), particularly in…
