Conflitti religiosi al tempo di Galla Placidia e Costanzo. A proposito di Olimpiodoro fr. 15 M
2010
L’articolo analizza alcuni frammenti olimpiodorei relativi alla lotta contro il paganesimo nell’età di Galla Placidia e Costanzo III. Il fr. 15 Müller delle Storie di Olimpiodoro narra la distruzione di un antico idolo pagano, che proteggeva la Sicilia dalle eruzioni dell’Etna e dalle incursioni, ad opera dell’amministratore dei beni siciliani della coppia imperiale. Stando allo storico tebano, l’abbattimento della statua, che aveva evitato lo sbarco dei Goti di Alarico nel 410, avrebbe comportato gravi conseguenze per l’isola, soggetta a partire da quel momento alle invasioni barbariche ed alla violenta attività del vulcano. Negli anni di Galla Placidia e Costanzo si dovette aprire una nuo…
Ab agrestibus et plebeis remedia: terapie mediche e riti magici in Marcello Empirico
2006
L’articolo analizza l’ambiente culturale gallico di IV-V secolo riflesso nel Liber de medicamentis, ricostruendo la figura dell’autore, i valori espressi nella praefatio, i modelli letterari utilizzati, cui si affiancano i remedia simplica et fortuita ab agrestibus et plebeis.
GUI Implementation of VCDtools, A Program to Analyze Computed Vibrational Circular Dichroism Spectra
2020
As computing power increases, vibrational circular dichroism (VCD) calculations on molecules of larger sizes and complexities become possible. At the same time, the spectra resulting from these computations become increasingly more cumbersome to analyze. Here, we describe the GUI implementation into the Amsterdam Density Functional (ADF) software package of VCDtools, a toolbox that provides a user-friendly means to analyze VCD spectra. Key features are the use of the generalized coupled oscillator analysis methods, as well as an easy visualization of the atomic electric and magnetic transition dipole moments which together provide detailed insight in the origin of the VCD intensity. Using s…
Transmediating argumentation : Students composing across written essays and digital videos in higher education
2016
This comparative study examined how university students built an argument in written essays and multimodal digital videos, and how their argumentation transmediated across these two mediums. Data analysis involved 1) analysis of content in both written essays and digital videos; 2) the development of transmediation visualizations to elucidate how ideas were transformed from essays into videos; and 3) multimodal analysis to understand the communicative affordances and constrains for argumentation with each medium. The findings revealed that the most common type of content in both essays and videos was supportive argumentation; however, the videos did not include any counter-argumentation. St…
Esquizofrènia tardana, un diagnòstic diferent?. Conceptualització i simptomatologia
2016
espanolLa esquizofrenia tardia se ha revelado como un diagnostico destacado por su controversia a lo largo del ultimo siglo. La polemica surgida en torno a este trastorno se centra en su marco psicopatologico y en sus diferencias y similitudes con la esquizofrenia temprana. Por ello, el objetivo de esta revision es conceptualizar el trastorno y esclarecer los sintomas, asi como delimitar si la esquizofrenia tardia deberia ser considerada como una categoria independiente. La presente revision utilizo como motor de busqueda la metabase de datos ProQuest Central, seleccionando un total de veintidos bases de datos. Se realizaron dos busquedas, utilizando los terminos «late onset schizophrenia» …
Investigating the affordances of a flipped mathematics classroom from an activity theoretical perspective
2020
Abstract Flipped Classroom as a pedagogical framework has gained popularity at secondary and tertiary levels of mathematics education, but there is a lack of research based on a solid theoretical foundation. This article considers the flipped mathematics classroom from the perspective of affordances and cultural–historical activity theory. The empirical background is based on semi-structured interview data from eight first-year computer-engineering students following 1 year of flipped classroom teaching. The thematic analysis of the data indicates that the flipped format offers a range of affordances at various levels of the activity system. This article advances research on affordances for…
First experimental study of photon polarization in radiative B0s decays.
2017
The polarization of photons produced in radiative $B^{0}_{s}$ decays is studied for the first time. The data are recorded by the LHCb experiment in $pp$ collisions corresponding to an integrated luminosity of 3fb$^{-1}$ at center-of-mass energies of $7$ and $8$TeV. A time-dependent analysis of the $B^{0}_{s} \to \phi \gamma$ decay rate is conducted to determine the parameter ${\mathcal{A}}^\Delta$, which is related to the ratio of right- over left-handed photon polarization amplitudes in $b \to s \gamma$ transitions. A value of ${\mathcal{A}}^\Delta=-0.98^{\,+0.46\,+0.23}_{\,-0.52\,-0.20}$ is measured. This result is consistent with the Standard Model prediction within two standard deviatio…
