L’ILLUSIONE DEL SAPERE: L’UNIVERSO DELLE FAKE NEWS. UN’INDAGINE ESPLORATIVA CON GLI ADOLESCENTI
Full text linkInformation and its use are essential elements within society and media culture since they help us understand what is happening around us. On the other hand, however, a series of information disturbances are spreading around due to the circulation of false and deliberately misleading information.
The “fake news” label has entered (not only) the political de-bate and the attention for the methods of online information ac-quisition highlights a growing concern about the impact of digital platforms on democratic and social life. In fact, the degree of vul-nerability of companies, institutions and individuals to manipula-tion by malicious media actors still needs to be studied.
This contribution presents the results of an exploratory survey, carried out using social networks, involving 290 teenagers. The sur-vey was aimed at detecting the relationship that teenagers have with fake news, their habits on the net, their ability to distinguish be-tween true news and false news, as well as to identify strategies and tools implemented by the school to develop critical & creative skills to recognize fake news. The results, although not to be gen-eralized, are comforting and surprising
Faculty Development e didattica laboratoriale a distanza. Un percorso di innovazione didattica con i futuri insegnanti
No full textIn linea con alcuni dei principi costitutivi della Faculty Development Research, ovvero lo sviluppo delle competenze didattiche del docente universitario in ordine alla promozione della persona in un processo di life long learning, si pone la necessità di una costante revisione dei modi e delle forme della didattica universitaria, con una spinta innovativa che punti, da un lato, alla riconfigurazione dell’impianto metodologico-didattico e, dall’altro, alla implementazione di un apprendimento attivo (Freeman et al., 2014; Kuh et al., 2008). In questa cornice, il laboratorio può rappresentare la modalità trasversale che caratterizza la didattica universitaria per promuovere nello studente una preparazione completa e capace di continuo rinnovamento, idonea per la promozione di un apprendimento significativo e in grado di creare un sapere nuovo partendo dai concetti e dai contenuti preesistenti nella struttura cognitiva della persona in formazione, resa “protagonista” del proprio apprendimento, pronta a generare nuove conoscenze stabili e durature (Ausubel, 2004). Nell’ambito del progetto di ricerca abbiamo previsto che al termine dell’azione sperimentale, attraverso le attività laboratoriali progettate e realizzate utilizzando il Problem-based Learning, sarebbero aumentate significativamente, nei 414 studenti del CdS in Scienze della Formazione Primaria, frequentanti in DAD il laboratorio di didattica generale, gruppo M-Z (n. 136) e di Docimologia (n. 308) (A.A. 2020/2021), prestazioni indicative dello sviluppo delle competenze comunicativo-valutative. Il percorso attivato ha visto protagonisti sia i docenti sia gli studenti e ha permesso, in modo specifico, ai docenti di potere riflettere sulla pratica didattica messa in atto per orientare i laboratori successivi
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
Palygorskite From Bolca, Italy - A Characterization By High-resolution Synchrotron-radiation Powder Diffraction and Computer Modeling
No full textA new find of the mineral palygorskite from Bolca, Vicenza, Italy is described. The mineral occurs in association with calcite and diaspore along the shear fractures and in the veins of secondary minerals in the Eocene marls of the Bolca quarry, a locality known for its well-preserved fossil specimens. Selected regions of the X-ray powder diffraction spectra (XRPD) were collected using X-ray synchrotron radiation and high-resolution parallel-beam geometry. The data are interpreted by comparison with the computer-simulated powder diffraction patterns relative to the proposed strcture models for palygorskite. Cell parameters and relative phase weight evaluation were obtained by model-constrained Rietveld refinement. The sample was also investigated by electron probe micro-analysis (EPMA), TGA and DTG analysis, and SEM imaging. The average material is a mixture containing about 60% orthorhombic palygorskite, 30 % monoclinic palygorskite, and less than 10 % calcite and diaspore impurities. The association of the two different varieties of palygorskite is in agreement with recent re-evaluation studies of the mineral from different localities, showing the ubiquitous presence of the two forms
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
