Ricerca com-partecipata e sperimentazione didattica in campo educativo
2022
Il saggio riflette sulla specificità della ricerca educativa e la accomnuna alla ricerca in campo sociale; ritrova infatti le connessioni nel valore politico, nelle ricadute sulla prassi, e nella prospettiva etica. In questo senso viene evidenziata la possibilità di connettere teoria, metodologia ed esperienza (e, ad un livello meta, di riflettere su tale connessione) e il fatto che questo processo si configura nei termini di una “apprendimento continuo”, sui piani individuale, di gruppo, istituzionale. Ritrovando l’origine di tale prospettiva nell’opera di Dewey (1929), viene quindi evidenziato lo stretto raccordo tra esperienza e pensiero, riflessione e pratica, presente in ogni processo …
Design, implementation and experimental results of an inductive power transfer system for electric bicycle wireless charging
2020
The use of renewable energy and the transformation of transport mode are crucial items for achieving an efficient and clean electrical mobility that allow being competitive on the market. In this context the interface between the power system and the Electric Vehicles (EVs) assumes a strategic role. Specifically, wireless energy transmission, based on Inductive Power Transfer (IPT), is an attractive solution for EVs charging. Moreover, the use of electric bicycles or kick scooters as mode of urban transport is continuously growing because they are lightweight, sustainable, easily parking, flexible and efficient transport devices. Owing to its benefits, the wireless power transfer can be con…
Comparative analysis of muon-capture and 0νββ-decay matrix elements
2020
Average matrix elements of ordinary muon capture (OMC) to the intermediate nuclei of neutrinoless double beta (0νββ) decays of current experimental interest are computed and compared with the corresponding energy and multipole decompositions of 0νββ-decay nuclear matrix elements (NMEs). The present OMC computations are performed using the Morita-Fujii formalism by extending the original formalism beyond the leading order. The 0νββ NMEs include the appropriate short-range correlations, nuclear form factors, and higher-order nucleonic weak currents. The nuclear wave functions are obtained in extended no-core single-particle model spaces using the spherical version of the proton-neutron quasip…
Analysis of light neutrino exchange and short-range mechanisms in 0νββ decay
2020
Neutrinoless double beta decay (0νββ) is a crucial test for lepton number violation. Observation of this process would have fundamental implications for neutrino physics, theories beyond the Standard Model and cosmology. Focusing on so-called short-range operators of 0νββ and their potential interplay with the standard light Majorana neutrino exchange, we present the first complete calculation of the relevant nuclear matrix elements, performed within the interacting boson model (IBM-2). Furthermore, we calculate the relevant phase space factors using exact Dirac electron wave functions, taking into account the finite nuclear size and screening by the electron cloud. The obtained numerical r…
Lo zerosei di fronte all’emergenza COVID. Esperienze, ricerche e riflessioni pedagogiche
2022
Il volume prende le mosse da un incontro on line organizzato il 28 novembre 2020 dal Gruppo SIPED Infanzia sul tema: Lo zero-sei di fronte all’emergenza COVID. In quella sede vennero proposte riflessioni particolarmente interessanti, che hanno trovato poi un approfondimento scientifico nei diversi contributi raccolti. È suddiviso in tre parti tra loro interrelate, che spaziano temporalmente dall’improvvisa chiusura totale dei servizi per l’infanzia a marzo 2020, fino alle prime esperienze di riapertura in nuovi assetti organizzativi nell’a.s. 2020-21. La situazione pandemica e le sue conseguenze pratiche, hanno generato criticità gestionali, oltre a preoccupazione e disorientamento nel pers…

Deux dictionnaires de littérature de l’abbé Antoine Sabatier de Castres
2017
Il Dictionnaire de Littérature di Sabatier de Castres (1770) è considerata la prima opera ad aver fatto uso del sintagma "dizionario di letteratura". L'aspetto innovativo di questo lavoro è tuttavia alquanto limitato a causa della sua vocazione didattica, che lo accomuna a un altro dizionario di Sabatier: il Dictionnaire des Passions, des Vertus et des Vices (1769). Esamineremo il modo in cui esso resta tuttavia un'interessante testimonianza del movimento enciclopedico nel quale finì per inserirsi. The Dictionnaire de Littérature of Sabatier de Castres (1770) is considered the first work to have made use of the syntagm "dictionary of literature". The innovative aspect of this works is, howe…
Mapping and quantification of cryptochrome expression in the brain of the pea aphid Acyrthosiphon pisum.
2021
Aphids are paradigmatic photoperiodic animals often used to study the role of the circadian clock in the seasonal response. Previously, we described some elements of the circadian clock core (genes period and timeless) and output (melatonin, AANATs and PTTH) that could have a role in the regulation of the aphid seasonal response. More recently we identified two opsins (C-ops and SWO4) as candidate input photoperiodic receptors. In the present report, we focus on the study of cryptochromes (cry) as photoreceptors of the circadian clock and discuss their involvement in the seasonal response. We analyze the expression of cry1 and cry2 genes in a circadian and seasonal context, and map their ex…
Resource Allocation and Computation Offloading for Multi-Access Edge Computing With Fronthaul and Backhaul Constraints
2021
Edge computing is able to provide proximity solutions for the future wireless network to accommodate different types of devices with various computing service demands. Meanwhile, in order to provide ubiquitous connectivities to massive devices over a relatively large area, densely deploying remote radio head (RRH) is considered as a cost-efficient solution. In this work, we consider a vertical and heterogeneous multi-access edge computing system. In the system, the RRHs are deployed for providing wireless access for the users and the edge node with computing capability can process the computation requests from the users. With the objective to minimize the total energy consumption for proces…
Collaborative Mobile Clouds: An Energy Efficient Paradigm for Content Sharing
2018
On the way toward enabling efficient content distribution, reducing energy consumption and prolonging battery life of mobile equipment, an emerging paradigm, i.e., mobile cloud, which is based on content distribution, was proposed. As a mobile platform that is oriented toward content distribution, mobile cloud is also foreseen as an energy-efficient solution for future wireless networks. The benefits of using CMC for content distribution or distributed computing from social networking perspectives have been studied earlier. In this article, we first present the concepts of CMC and then discuss the energy-efficiency benefits from the system-level point-of-view as well as open challenges in d…
