Il Duomo di Pisa. Architettura e scultura architettonica dalla fondazione al Quattrocento
No full textLe fasi della cattedrale di Pisa dalla sua fondazione alla fine del Medioevo vengono qui individuate e analizzate alla luce dei rapporti tra committenza religiosa e civile e artisti. Le scelte tipologiche, formali e stilistiche quali oggi appaiono dal monumento sono così riportate alle loro ragioni fondanti, e per la prima volta si avanzano ipotesi sui rapporti tra funzione liturgica e organizzazione degli spazi nella progettazione della basilica nel secolo XI. Di ciascuna fase vengono poi indicate le componenti culturali e i rapporti con gli altri ambiti artistici regionali coinvolti come pure i rimandi ai grandi momenti del passato cui ci si intendeva riconnettere

On Leonardo and a fossil whale: a reappraisal with implications for the early history of palaeontology
No full textA recent reappraisal of two passages in Leonardo da Vinci’s Codex Arundel, in which the then young Leonardo reports on visiting a cave and on some sort of ʽmarine monster’, has led to the proposition that Leonardo observed and wrote on fossil remains of a whale preserved in a cave. Whereas this hypothesis appears reasonable overall, some problems persist in accepting the purported location in which Leonardo would have observed the fossil. Here we provide a new analysis of the aforementioned passages by Leonardo which allows us to confirm that Leonardo saw a fossil whale and recognised it as such. However, his observation did not occur in a cave, but likely along the flank of a hill, as relatively common for Tuscan Pliocene fossil cetaceans. Leonardo seemingly made taphonomic observations on the fossil whale and inferred that a considerable amount of time must have passed from the death of the whale in the sea to allow for its eventual discovery on land–an observation that likely contributed to shaping Leonardo’s later thoughts on sedimentation and fossilisation. This might represent Leonardo’s earliest text devoted to a palaeontological theme. Moreover, it comprises the first known description of a cetacean fossil
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
