Competenze digitali trasversali e traduzione cooperativa. Esperienze didattiche innovative fra università e scuola
No full textNell’ambito degli studi sulla didattica della traduzione, alcuni contributi recenti si sono soffermati a lungo sulle interconnessioni fra teoria della traduzione, approcci e metodi didattici, e teoria della complessità. In particolare, sulla scia degli studi di Kiraly (2006, 2015), Calzada Perez sottolinea la necessità approccio basato su una epistemologia positivista che ispirandosi ad un costruttivismo di stampo Vygotskiano che rimandi alla triade “autonomy, experience and expertise” (Kiraly 2000; Perez 2019) con una apertura nei confronti dell’’emergentismo’ - il riconoscimento cioè di aspetti di ‘complessità’ nell’ambito dell’apprendimento, che sfuggono a qualsiasi concezione lineare e trasmissionista della conoscenza (Calzada Perez 2019).
Questa visione della didattica e dell’apprendimento nel campo della traduzione ha portato sempre più a ipotizzare la necessità di adottare attività complesse, basate su progetti autentici.
È sulla base di questi presupposti che il presente contributo si propone di illustrare alcune esperienze di didattica innovativa basate sull’interazione con i progetti Wikimedia sia all’interno dei corsi universitari, sia in collaborazione con scuole: per quanto riguarda l’università verranno prese ad esempio le Translatathon, le maratone di traduzione svoltesi presso l’Università degli Studi di Bari Aldo Moro, e per la scuola un progetto di PCTO svolto presso l’ITIS Pitagora di Taranto

Peptide self‐assembled nanostructures: from models to therapeutic peptides
No full text: Self-assembly is the most suitable approach to obtaining peptide-based materials on the nano- and mesoscopic scales. Applications span from peptide drugs for personalized therapy to light harvesting and electron conductive media for solar energy production and bioelectronics, respectively. In this study, we will discuss the self-assembly of selected model and bioactive peptides, in particular reviewing our recent work on the formation of peptide architectures of nano- and mesoscopic size in solution and on solid substrates. The hierarchical and cooperative characters of peptide self-assembly will be highlighted, focusing on the structural and dynamical properties of the peptide building blocks and on the nature of the intermolecular interactions driving the aggregation phenomena in a given environment. These results will pave the way for the understanding of the still-debated mechanism of action of an antimicrobial peptide (trichogin GA IV) and the pharmacokinetic properties of a peptide drug (semaglutide) currently in use for the therapy of type-II diabetes
Individual differences in numerical skills are influenced by brain lateralization in guppies (Poecilia reticulata)
No full textA large number of studies showed that fish possess numerical abilities similar to those reported in mammals and birds. However, inter-individual differences in numerical performance are repeatedly found with different types of stimuli and methodological approaches. A recent study on guppies, Poecilia reticulata, suggested that strongly lateralized individuals, assayed for eye preference in a mirror test, were better than poorly lateralized ones when tested for numerical abilities in a natural shoal choice. This study, however, had a potential confound; both the mirror and the shoal choice tests exploit the higher sociality and schooling tendencies in guppies. It is therefore possible that sociality rather than lateralization per se may have been responsible for the observed differences. In the present study, guppies were selected for high or low lateralization using a non-social test, the detour test. Subjects preferentially turning rightward (RD) or leftward (LD) when facing a dummy predator visible behind a barrier proved better than those with no preference (NL) when required to choose the larger of two groups in a shoal choice test. Our study supports the notion that inter-individual differences in the numerical abilities of guppies are related to their degree of cerebral lateralization
The Life and Works of Joachim of Fiore - An Overview
No full textJoachim of Fiore (c.1135-1202) remains one of the most fascinating and enigmatic figures of medieval Christianity. He may well be called the most influential apocalyptic thinker after the author of the Book of Revelation. In his own time, Joachim was an influential advisor to the mighty and powerful, widely respected for his prophetic exegesis and decoding of the apocalypse. This article aims to present his life and his work
Preliminary Assessment of Photonic Solutions Based on C-Band VCSELs for Multi-Tb/s Metro Networks
No full textC-band InP vertical cavity surface emitting laser (VCSEL) exploitation can be appealing also for high-capacity transmission over hundreds of kilometres. Long-wavelength VCSELs can represent an alternative solution for the development of transmitters with reduced cost, power consumption and footprint by adopting direct modulation (DM) and single sideband (SSB) discrete multitone (DMT) modulation to achieve dense wavelength
division multiplexing (WDM) granularity. Due to numerous hops between nodes inside metropolitan area networks the effect of filtering can severely impact the transmission performance. We present preliminary experimental assessments of DM VCSEL sources with multi-carrier modulation formats, for more than 50 Gb/s per-channel transmission to target a metro network including nodes, handling 25-GHz granularity
Identity markers in the South-western Fazzan : Were the people of the Tanzzuft/Tadrart Akakus region Garamantes?
No full textAccording to Herodotus’s Histories, the people living a ten day’s journey to the west of the Garamantes was the Atarantes As suggested by Liverani, if the Garamantes are to be placed in the Wadi al-Ajal around Jarma/Garama, this would likely locate the Atarantes in the Wadi Tanzzuft/Tadrart Akakus region Fig. 3.1). Archaeological research over the last two decades has considerably improved our knowledge of Saharan civilisations that developed from the early first millennium BC to the late first millennium AD. It is now possible to get a deeper insight on how the people living in the Wadi Tanzzuft/Tadrart Akakus region expressed their identity through material culture and behaviour and their relation to trajectories in Garamantian culture
Tearing mode stability with equilibrium flows in the reversed-field pinch
No full textThe influence of certain equilibrium flows on the stability of tearing modes in the reversed-field pinch is investigated. By solving the linearized magnetohydrodynamic equations in cylindrical geometry, the tearing mode stability factor Δ′ is calculated for a variety of axial flow profiles which have nonzero shear away from the rational surface, including flows localized entirely in the external, ideal region of the tearing mode. It is found that both m = 1 and m = 0 modes are destabilized by an axial flow localized near the edge of the plasma. This is the kind of flow that might be generated by any physical process creating an edge-localized radial electric field. A global flow profile with shear over the middle region of the plasma, simulating the differential rotation of core and edge modes observed in some reversed-field pinch discharges, is found to have a destabilizing effect on the m = 1 mode, while leaving the stability parameter of the m = 0 mode practically unchanged. The possible connection of these results with features of the spontaneous enhanced confinement regime in the Madison Symmetric Torus is discussed
