Dall'archeologia all'architettura:il rilevamento per la comprensione dello spazio costruito
No full textIl testo sviluppa la ricerca avviata nella tesi di dottorato e si arricchisce di nuovi rilievi e restituzioni grafiche. Vengono sottolineati i risultati della collaborazione tra le diverse specifiche competenze degli archeologi e degli architetti esponendo gli esiti dello studio condotto unitariamente sull’architettura e sulle componenti edilizie.
Lo studio della Casa dell’Ancora è partito da una analisi della documentazione grafica esistente alla scala urbana, utile alla determinazione di un progetto di presa delle misure orientato anche alla verifica di anomalie e differenze riscontrate nel confronto tra i vari disegni a disposizione. Nel testo sono illustrate le tecniche di rilevamento adottate e l’applicazione del programma di restituzione fotogrammetrica Photomodeler nel rilievo del braccio Est del criptoportico. I risultati del rilevamento sono descritti evidenziando il ruolo del disegno nella comprensione dell’architettura, anche in relazione alla determinazione delle diverse fasi edilizie. L’analisi condotta sulle strutture ha consentito di programmare, insieme agli archeologi, lo scavo che ha permesso il ritrovamento dei resti del vecchio braccio Ovest del portico di prima fase e, conseguentemente di spiegare l’anomalo innesto delle arcate del criptoportico nell’angolo Ovest del giardino. La proposta di restituzione grafica, che chiude lo studio della Casa, è basata sull’idea che la restituzione grafica delle piante, alla scala 1:50, possa seguire criteri analoghi a quanto adottato negli alzati, e dare conto delle tecniche edilizie utilizzate anche se solo relativamente alla quota di sezione. Questo consentirebbe di non demandare ad una simbologia astratta, e quindi a una legenda, informazioni su materiali e tecniche. Il paragrafo sulle prime ipotesi per un progetto di recupero e valorizzazione della casa dell’Ancora, risponde ad una amichevole sollecitazione dell’allora Soprintendente Pietro Giovanni Guzzo, e graficizza, in maniera molto schematica, ragionamenti condotti sulla necessità di riconsiderare e rivalutare non solo lo spazio diffuso tra i resti archeologici, ma la consistenza edilizia dei singoli manufatti.The text carries out research initiated in my doctoral thesis and is enriched with new surveys and graphic renderings. The results of the collaboration between archaeologists and architects with their different expertises are highlighted, showing the findings of the study made on architecture and building components.
The study of the Casa dell’Ancora has started from an analysis of the existing graphic documentation at the urban scale, useful for planning a project to take measurements which is aimed also at verify anomalies and differences found in the comparison of the available drawings.
Survey techniques which have been used and the application of the Photomodeler photogrammetry software in the survey of the east wing of the cryptoporticus are described in the text. The survey results have been described highlighting the drawing role in the understanding of architecture, also with relation to the definition of the different building phases.
The structures analysis has made it possible to plan, with archaeologists, the excavations which have led to the finding of the remains of the old west wing of the first-phase portico making it possible to explain the anomalous intersecting of the arcades with the cryptoporticus in the west corner of the garden.
The proposal of graphic rendering, which terminates the study of the Casa, is based on the idea according which the plans graphic rendering, at a scale of 1:50, can follow criteria similar to what has been adopted in the elevations, and explain the building techniques which have been used even if only in relation to the section elevation. It would made it possible not to describe information on materials and techniques with an abstract symbology, i. e. a key. The paragraph dealing with the first hypothesis about a casa dell’Ancora renovation and enhancement project, grants a friendly request of the then Superintendent Pietro Giovanni Guzzo, and, in a very schematic way, makes reasonings on the need to reconsider and revalue not only the widespread space among the archaeological remains but also the building consistency of each manufacture graphic.

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
