Il glossario TECT: uno strumento lessicale per la schedatura della pittura parietale
No full textl volume raccoglie i contributi della Giornata di studio tenutasi a Padova il 20 marzo 2014 dal titolo "La pittura frammentaria di età romana. Metodi di catalogazione e studio dei reperti", organizzata con l'obiettivo prioritario di presentare ad un pubblico di specialisti le prime fasi del progetto TECT, il cui nome deriva dall'abbreviazione del termine latino tectorium (intonaco), sviluppato al fine di creare una banca dati delle pitture parietali di età romana rinvenute in Italia settentrionale.
La "filosofia" del database TECT viene esplicitata nel volume, non solo tramite la presentazione della scheda, ideata nell'ambito del progetto con lo scopo di sistematizzare le evidenze archeologiche (A. Didonè, G. Salvo), ma anche attraverso la proposta di un glossario - pensato per uniformare la descrizione delle testimonianze pittoriche e per facilitarne la ricerca - le cui fasi di elaborazione vengono illustrate in questi atti (R. Helg, A. Malgieri)
The surprising rolling spool: librational motion and failure of the pure rolling condition
No full textIn a previous work (Onorato P, Malgieri M, Mascheretti P and De Ambrosis A 2014 The surprising rolling spool: experiments and theory from mechanics to phase transitions Eur. J. Phys. 35 055011) an asymmetric rolling spool (ARS) was investigated as a simple model for a second-order phase transition. Here, we deepen the study of this system to address critical aspects related both to the characteristic of the oscillatory anharmonic motion and to the role of friction forces in determining it. The experimental data show that for largely asymmetric bodies the rolling condition is not reliably fulfilled because the intensity of the friction force goes below the needed value to ensure rolling

Gianclaudio Malgieri, Vulnerability and Data Protection Law
No full textThe article reviews the latest work by Gianclaudio Malgieri, Vulnerability and Data Protection Law, 2023. In the book, Malgieri argues that personal variables of data subjects, which makes them vulnerable in the digital ecosphere, have (and, in prospective terms, could have more) relevance for data protection laws. As this article shows, there are several reasons why Malgieri’s volume is a must-read for all private lawyers interested in the impact of new technologies on people and the law
Bubble: Experimenting with Feynman’s sum over paths approach in the secondary school
No full textWe discuss a teaching experiment on the introduction of elements of quantum physics already at the level of the fourth year of high school (17–18 years old students) using Feynman’s sum over paths approach. More precisely, the educational sequence is constructed on the juxtaposition of the wave and quantum theories of light, and it constitutes an attempt to anticipate the current status of the past, secular debate on the nature of light to young students, while providing them with a unifying perspective on different approaches, models and theories which are encountered in high school. The experimentation is part of the research on quantum physics education in secondary school conducted by the Physics Education group in Pavia, and it was developed by the author as a thesis work in the context of the IDIFO-6 Master coordinated by the University of Udine. The focus of the work is on the gradual introduction of innovative elements in the traditional high school didactics. Analysis of the experimentation data shows very rich and complex patterns, allowing to identify activities which may be more productive for students and to uncover weak points and student’s difficulties
Esperienze di formazione insegnante a seguito della revisione della seconda prova di maturità nei Licei Scientifici, 2015-2018 - Initiatives for teacher professional development following the revision of the final exam for Liceo Scientifico, 2015-2018

No full textA low cost spectrometer assembled in the laboratory is used to obtain and analyse spectra of different sources with the help of a digital camera and image processing software. The article shows that this apparatus, easily reproducible by the students themselves, allows to realize experimental activities, such as the estimation of Rydberg’s constant and the measurement of the transmission band and the emission peaks of coloured inks, suitable for introducing basic topics in modern physics
Colours of the Street: Form and Meaning of Facade Paintings at Pompeii and Herculaneum
No full textThe painted decoration was an important feature of the urban landscape of the Vesuvian cities and characterized several private and public buildings. A variety of colours and pictures that have unfortunately disappeared under the attack of the elements, completely altering the original appearance of the streets. Based on a complete catalogue of the extant decorations and on the analysis of archival material, the paper investigates this peculiar use of wall-painting through a new approach, considering the facade and its decoration as a result of a balance between private needs and ambitions, influenced also by functional and aesthetic characters of the quarter
