Museo delle Scienze Geologiche e Archeologiche dell'Isola di Pianosa
Get PDFIl Museo è nato con il progetto: “Pianosa: viaggio verso l’Isola della Scienza”, che comprendeva numerose azioni, finalizzate alla valorizzazione dei beni geologici e archeologici di cui l’isola è molto ricca. Il Progetto è stato realizzato con fondi del Ministero dell’Università e della Ricerca acquisiti tramite Bando competitivo cui il Parco dell’Arcipelago Toscano ha partecipato in partnership con l’Università di Siena, La Soprintendenza Archeologia Belle Arti e Paesaggio per le Province di Pisa e Livorno, l’Associazione per la Difesa dell’Isola di Pianosa e il Comune di Campo nell’Elba. Il Museo contiene rocce, fossili e reperti archeologici che sono tornati permanentemente sull’isola, luogo deputato alla loro conservazione, arricchendo la memoria naturalistica e storica di Pianosa. Molti degli arredi costituivano beni a magazzino inutilizzati di UNISI, che li ha donati al Parco specificatamente per il Museo, innescando con questo un percorso virtuoso di risparmio e di riutilizzo di beni pubblici, esaltato, inoltre, dalla stretta collaborazione fra i partner di progetto cui si è aggiunto il sostegno dell’Amministrazione Penitenziaria di Porto Azzurro. Il Museo contiene anche un laboratorio, un’aula conferenze con 40 posti e un’aula di microscopia, destinati a sostenere le attività didattiche e una biblioteca, dove l’Associazione ha depositato molti libri destinati al prestito ma soprattutto la collezione di testi, molti originali storici, che trattano di Pianosa.The museum was born with the project: "Pianosa: journey to the Island of Science", which includes several actions, aimed at enhancing the geological and archaeological heritage of the island. The project was funded by the Ministry of University and Research with funds from a competitive announcement in which the Arcipelago Toscano National Park participated in collaboration with the University of Siena, the Superintendency of Archeology, Fine Arts and Landscape for the Provinces of Pisa and Livorno, the Association for the Defense of the Pianosa Island and the Municipality of Campo nell'Elba. The museum contains rocks, fossils and archaeological finds that permanently return to the island, a place dedicated to their conservation, enriching the natural and historical memory of Pianosa. Many of the furnishings were unused assets of UNISI, which donated them to the Park specifically for the museum, thus triggering a virtuous path of saving and reusing public goods, enhanced by the close collaboration between the project partners and the essential support of the Porto Azzurro Prison Administration. The museum also contains a laboratory, a 40-seat conference room and a microscopy room, dedicated to support educational activities, and a library, where the Association has deposited many books intended for loan, but above all it has placed its collection of texts, many historical originals, which deal with Pianosa
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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
