3D Coupled Thermo-Electromagnetic Modelling of Superconducting MgB2 Coils
No full textThe numerical simulation of complex, nonlinear and coupled, electromagnetic and thermal dynamics involved in the quench phenomena
of Magnesium Diboride (MgB2) superconducting magnets requires a suitable modeling of the interaction among the different
aspects. As a matter of fact, magnets wound using MgB2 tapes are characterized by material parameters and working temperatures
leading to different behaviors with respect to either Low superconductors (LTS) and High (HTS) superconductors, and thus requiring
special care in the modeling of quench diffusion phenomena. In this paper, a 3-D finite-element method (FEM) model able to
cope with such phenomena is presented and model predictions are compared to experimental data
Processi educativi e interculturalità: riflessioni e problematicità pedagogiche
No full textLa tematica dell’interculturalità rappresenta una delle sfide più impegnative, che investe l’educazione stessa intesa nella sua accezione più ampia, come testo da scrivere ed interpretare alla luce di un contesto.
Il saggio ricerca una possibile paradigmaticità culturale, epistemologica e pedagogica della questione intercultural
La cultura dell'Altro
No full textIl capitolo tratta della costruzione dell'Alterità in relazione all'Identità come risultato di una dinamica culturale che coinvolge individui e gruppi storicamente determinati. Dunque, la concezione dell'Alterità in un determinato contesto si costruisce in relazione alla definizione dell'Identità e all'individuazioni di tutti gli elementi materiali e simbolici che la caratterizzano. In definitiva una relazione culturale che si sviluppa su dinamiche basate sul potere di attribuire un senso al contingente. Tali dinamiche sono fondamentali per capire come la figura e il concetto di "altro" possano nascere per "proiezione poietica"
The Fields of Digital Research: topics and developments
No full textIn recent decades, the Internet - and technologies that fall into the category of what are called ICI - have taken on a central role in people's lives. Every aspect of life seems to be permeated by the incursion of digital resources and technologies, to the point that sociology has begun to question how these redesign some phenomena that sociology, as a science of "social facts", has always questioned and focused on. What is being called into question, in a logic that goes from micro to macro, are the classic sociological conceptions of identity, of the nature and formation of social bonds, of the structures and dimensions of the collective imagination. According to recent data from ... smartphone users are % and own a computer %. Although a digital divide persists in certain areas of the world and for certain social categories, the centrality that these tools assume for people is evident, influencing their decision-making processes, attitudes, values and imaginations. It therefore seems increasingly necessary to add as a third element of the object of sociology - which as is known studies the relationship between the individual and society - that of the media, which here assume a dual role: on the one hand they are a place of social conditioning, in a structural sense, to the extent that digital spaces are also contexts in which new forms of power and control are highlighted, on the other hand they are places of identity expression and participation, to the extent that these environments are themselves the result of the interaction and communication that users give life to in digital spaces
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
