Gian Gastone de’ Medici (1671-1737), ultimo Granduca: committenza, inclinazioni del gusto, relazioni artistiche
No full textIl presente lavoro si è posto come obiettivo una quanto più veritiera ricostruzione della figura dell’ultimo Medici come collezionista d’arte, scevra da quella morbosa attenzione che spesso la storiografia ha riservato alla presunta depravazione del sovrano, limitandosi a presentare le risultanze documentarie per quel che sono, rimanendo in tal modo aderente il più possibile alla realtà delle cose per la voce dei documenti, delle cronache contemporanee e delle note manoscritte rintracciate presso l’Archivio di Stato di Firenze. Pertanto, si è cercato di fornire nuovi elementi per procedere a una doverosa operazione di rivalutazione della figura di Gian Gastone de’ Medici, spesso tralasciata dagli studi sul collezionismo mediceo, anche a causa della mancanza di indispensabili tracce documentarie. Gli esiti della ricerca hanno quindi il pregio di aver tracciato un ritratto più sfaccettato della figura inedita di Gian Gastone come amatore d’arte e collezionista. La prassi da lui inaugurata si differenzia da quelle più canoniche portate avanti dai suoi due fratelli Ferdinando e Anna Maria Luisa, più in linea con un mecenatismo di tipo tradizionale, ispirato ai modi del padre Cosimo III. Viceversa l’ultimo Medici fu meno incline a rivolgersi ai maestri attivi nella Galleria dei Lavori, per ampliare la gamma delle sue scelte a un più ampio ventaglio di artisti e artigiani, le cui opere gli venivano proposte da mercanti e intermediari che si avvicendavano copiosamente a corte
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
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
