LA VILLA DEI VOLUSII SATURNINI A LUCUS FERONIAE: AMBIENTI VIRTUALI PER LA RICERCA ARCHEOLOGICA
Get PDFLa sempre maggiore diffusione di progetti di archeologia virtuale e di visualizzazione digitale del patrimonio culturale spingono gli esperti del settore a una riflessione epistemologica sulla trasparenza e sulla scientificità dei risultati ottenuti. Tale riflessione ha dato vita, nel 2009, alla “London Charter for the Computer-based Visualisation of Cultural Heritage”, che ha stabilito precisi principi e criteri da seguire per garantire la scientificità dei prodotti di archeologia virtuale. Per ottemperare a tali indicazioni, all'inizio del progetto “Museo Virtuale della Valle del Tevere”, che si proponeva, fra le altre cose, di ricostruire la Villa dei Volusii Saturnini, si è deciso di costruire un Sistema Informativo Semantico che consenta agli utenti del Museo Virtuale di accedere ai dati relativi alle singole parti del modello e della villa. Questo garantisce l'effettiva trasparenza delle scelte interpretative effettuate dai ricercatori per la ricostruzione virtuale del sito e di esaminare in modo critico i dati disponibili.
Da tale riflessione di carattere generale è scaturita la ricerca condotta per il dottorato di ricerca: la scientificità del progetto di ricostruzione virtuale della villa è stata sostenuta da una rigorosa e accurata ricerca archeologica, mirata alla raccolta di tutta la documentazione disponibile sul sito. In seguito, si è provveduto alla realizzazione del Sistema Informativo Semantico: un ambiente tridimensionale interattivo online, nel quale è possibile accedere a tutti i paradata relativi al sito archeologico. La tesi di dottorato costituisce il primo caso di applicazione del Sistema Nubes sviluppato dal Laboratorio MAP-GAMSAU del CNRS per un sito archeologico interamente ricostruito digitalmente. Il caso della Villa dei Volusii è particolarmente significativo per lo sviluppo di un Sistema Informativo Semantico perché si tratta di un sito archeologico di grande pregio, il cui scavo è avvenuto in condizioni di emergenza e la cui conoscenza è inficiata da numerose lacune documentarie. Nel corso della realizzazione del progetto, è stato necessario riesaminare interamente tutta la documentazione e i dati esistenti per la comprensione del sito, riordinarla e integrarla con i dati raccolti durante nuove operazioni di rilievo e nuovi dati di scavo forniti dalla Soprintendenza per i Beni Archeologici dell'Etruria Meridionale. La creazione del sistema semantico permette di comunicare efficacemente e in modo interattivo agli utenti e alla comunità scientifica le informazioni che si celano dietro alla ricostruzione virtuale, ma anche di creare le condizioni per un riesame generale delle conoscenze sul sito archeologico ed è quindi di stimolo per una ripresa degli studi sull'argomento.The increasing use of virtual archeology and digital visualization projects of cultural heritage in the industry pushes the experts to an epistemological reflection on transparency of the scientific results obtained. This reflection has led, in 2009, to the "London Charter for the Computer-based Visualisation of Cultural Heritage", which established clear principles and criteria to be followed to ensure the scientific nature of the products of virtual archeology . To comply with these directions, at the beginning of the project " Virtual Museum of the Tiber Valley", which aimed, among other things, at the virtual reconstruction of the Villa Volusii Saturnini, it was decided to build a Semantic Information System that allows users to Virtual Museum to access to the para-data related to the individual parts of the model and the villa. This ensures the effective transparency of the interpretive choices made by the researchers for the virtual reconstruction of the site and to examine critically the available data .
This reflection of a general nature gave rise to the research conducted for the PhD : the scientific design of the virtual reconstruction of the villa was supported by a rigorous and thorough archaeological research, aimed at collecting all the documentation available about the archaeological site. As a result, the Semantic Information System was conceived as a three-dimensional interactive on-line environment, where users can access all para-data related to the archaeological site. The PhD thesis is the first case of application of the Nubes platform, developed by the Laboratory MAP-GAMSAU of the CNRS for an archaeological site entirely reconstructed digitally. The case of the Villa Volusii is particularly significant for the development of a Semantic Information System because it is an archaeological site of great value, whose excavation took place under emergency conditions, the knowledge of which is affected by numerous documentary gaps. In the course of the project, it was necessary to fully re-examine all the documentation and the existing data for the understanding of the site, reorder and integrate it with new data collected during survey operations and new excavation data provided by the Superintendence for Archaeological Heritage of Southern Etruria. The creation of the semantic system allows to disseminate effectively and interactively to the users and the scientific community the information that is hidden behind the virtual reconstruction, but also to create the conditions for a general review of knowledge of the archaeological site and is therefore a stimulus for a resumption of studies on the subject
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
Tra uomini e dei: funzione e ruolo di alcuni oggetti negli specchi etruschi
No full textThe contribution focuses on the possibility that Greek instances might have been recalled to perform situations and roles in other spheres of sense, directly issued from the Etrusca Disciplina, and not really from the need to represent local myths, legends and stories. In fact, the link among the Greek images selected for the scenes on the mirrors seems to address the very core of the apparatus of the Etruscan religion
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
