Different scenarios of electric mobility: Current situation and possible future developments of fuel cell vehicles in Italy

2020

The diffusion of electric vehicles in Italy has started but some complications weight its spread. At present, hybrid technology is the most followed by users, due particularly to socioeconomic factors such as cost of investment and range anxiety. After a deep discussion of the Italian scenario, the aim of the paper is to recognize whether fuel cell technology may be an enabling solution to overcome pollution problems and respect for the environment. The opportunity to use fuel cells to store electric energy is quite fascinating&mdash

E-portfolio e flipped classroom: un’indagine esplorativa con i futuri insegnanti di scuola primaria

2023

Il contributo intende far riflettere sul tema della formazione dei futuri insegnanti di scuola primaria, a partire dall’impiego dell’e-portfolio come dispositivo innovativo per promuovere l’acquisizione della competenza riflessiva e autovalutativa all’interno della flipped classroom. La ricerca, che ha coinvolto 154 studenti del Corso di laurea magistrale in Scienze della Formazione Primaria dell’Università degli Studi di Palermo, che frequentavano il corso di Docimologia nell’anno accademico 2020/2021, presenta i presupposti teorici, gli obiettivi e le modalità operative di un percorso che ha visto l’impiego dell’e-portfolio nella flipped per promuovere lo sviluppo delle competenze docimol…

Produits transformés, entre science et science-fiction

2021

En science-fiction, le futur de nos tables a souvent été mis en scène : des bouilles nutritives de Matrix aux pâtes d'insectes de Snowpiercer, ou bien aux légumes géants de Woody et les robots. Comment mangerons-nous dans le futur ? Nos goûts changeront-ils comme nos plats? Et dans l'espace, est-ce que la mayonnaise prendra sur l'ISS?

GARCH models with changes in variance: An approximation to risk measurements

2003

This study aims to model volatility as an approximation to an optimum measurement of stock market risk because of the importance of this concept for, among other things, the proper management of portfolios. Following the proposal of Lamoureux and Lastrapes (1990), the authors consider that the high degree of persistence detected in GARCH models arises from a poor specification of the equation of the variance due to not considering the possible deterministic changes in the unconditional variance of the financial series. To determine the point in time as well as the duration of these changes, the proposal made by Inclan and Tiao (1994) is used. As an empirical application, whether or not the …

Notes per a una estilística dels temps verbals

2000

Tenses constitute a complex system of oppositions based on time, aspect, and temporal distance. Taking these oppositions as basic, this article deals with the stylistic properties that verbal tenses acquire in discourse. In addition, it presents an analysis of some stylistically marked uses of the imperfect, the future, the conditional, and the past perfect. In all these cases, the verbal tenses keep some of their basic properties but introduce temporal or aspectual changes that lead to pragmatic and stylistic changes closely related to certain narrative effects.

The learning curve, accuracy, and interobserver agreement of endoscope-based confocal laser endomicroscopy for the differentiation of colorectal lesi…

2012

Background: The endoscope-based confocal laser endomicroscopy (eCLE) system allows in vivo imaging of colorectal epithelium. Little is known about the learning curve for accurate interpretation of confocal images acquired with eCLE. Objective: To determine the learning curve of eCLE, its diagnostic accuracy, and the intra- and interobserver agreement for the differentiation of colorectal lesions. Design: Post hoc assessment of selected eCLE images. Setting: Academic centers. Patients: This study involved colonoscopic images from 47 patients. Main Outcome Measurements: Learning curve of eCLE, accuracy, and intraobserver and interobserver agreement. Methods: Three endoscopists received a shor…

La explicación del riesgo de sequía en la Geografía escolar. Una exploración desde los manuales escolares de Ciencias Sociales (Educación Primaria)

2021

espanolEn la region mediterranea uno de los principales riesgos naturales son las sequias. Este fenomeno se ha agravado en las ultimas decadas debido al incremento de la vulnerabilidad asociadas a actividades humanas y, segun los escenarios futuros de cambio climatico, se preve que aumente la peligrosidad (mayor intensidad y frecuencia de los periodos secos). El objetivo de este trabajo es llevar a cabo un analisis de como se explica el riesgo de sequia en los manuales escolares de Ciencias Sociales (3er ciclo de Educacion Primaria) en la Comunidad Valenciana (Espana). A partir de la consulta de estos recursos (las 5 editoriales mas utilizadas), los resultados obtenidos indican que esta tem…

Future 0,0,0. Urban/human futures

2014

“Futurus” in Latin is the future participle (!) of the verb to be, then, we literally translate it into “what will be” and, in the classical ontology of the pre-Socratic period, being does not derive from the Man who scratches time and bends the path of history producing effects reduced to the tickle done to a pachyderm. Will the future, then, inexorably be independent from the human will? Not necessarily. the futures If we try to distinguish the future as the time line that goes to infinity as a positive future like a projection of human action in time, two views will come out: a static view - far in the coordinates x, y, t - and a dynamic vision which tends to reach a point of coordinates…

The effectiveness of the GoKoan e-learning platform in improving university students’ academic performance

2021

Abstract The GoKoan e-learning platform supports face-to-face training in an educational community. Its aim is to optimise the way and the time of study in order to improve academic performance. To evaluate the GoKoan platform’s effectiveness as a tool for improving academic performance, an experimental study was carried out using a sample of 171 university students enrolled in the psychology degree programme who were randomly assigned to the two different conditions (the experimental group: traditional learning + e-learning with the GoKoan platform; and the control group: traditional learning without e-learning). The findings showed that using GoKoan had a positive impact on the students’ …
