Le capselle paleocristiane di Mariano Comense
No full textIn 1574, the demolition of the altar of the Romanesque baptistery of St. John the Baptist in Mariano Comense led to the discovery of a stone capsule in the form of a sarcophagus, now kept in the parish archives; the reliquary contained fragments of figured silver-leaflets, the remains of a bone box, and textile fragments. The contribution reconsiders the capsella and its contents, also proposing a reconstruction of the bone cassette to which the silver laminettes were attached
Lo studio dei popolamenti del passato nelle aree montane in Val Cavargna (Provincia di Como, Alpi Lepontine)
No full textGli studi delle aree montane e della storia dei popolamenti sono spesso trascurati. La montagna si trova in una situazione di svantaggio, in quanto è un ambiente che può rendersi difficile da esplorare e si trova ad essere attualmente di interesse marginale. Lo spopolamento della montagna sta causando problemi ambientali: sono andati sempre più diminuendo interventi a difesa del territorio, necessari per mitigare i rischi di dissesto idrogeologico, incendi incontrollati, erosione del suolo. Si rende quindi necessario comprendere la storia dei popolamenti in alta quota durante i millenni ed esaminare le conseguenze sull’ambiente delle attività legate allo sfruttamento delle risorse, per affrontare le criticità del rapporto uomo-ambiente e per cogliere le potenzialità dell’ambito montano.
Alcune escursioni di Lanfredo Castelletti sulle montagne della Val Cavargna, durante le quali sono stati riconosciuti livelli di materiale carbonioso con spessori anche fino a quasi il metro (1994 e 1997), sono state l’inizio di una lunga ricerca sistematica, in cui Lanfredo è stato costantemente attivo, iniziata nel 2002 e proseguita per un decennio
L’importanza delle collezioni scheletriche nella ricostruzione della storia “umana”: Milano inizia a raccontarsi dai suoi scheletri
No full textSe Lanfredo Castelletti non avesse negli anni ‘80 con
grande lungimiranza portato nel suo laboratorio lo studio
dei resti umani antichi, se non avesse trasmesso ai giovani
intorno a lui (tra cui una allora giovane antropologa, Cristina
Cattaneo, autrice di questo contributo), il fascino e la
potenza della ricostruzione del passato attraverso la scienza,
la collezione e i progetti di cui andremo brevemente a parlare
probabilmente non esisterebbero. Ed è quindi anche grazie a
lui che giovani archeologi ed antropologi, come i coautori di
queste pagine Mirko Mattia e Lucie Biehler-Gomez,
potranno godere della sua grande intuizione
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

No full textVariations 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
