"C'era una volta". La ceramica medievale nel convento del Carmine a Siena
No full textIl CD-ROM presenta, in forma multimediale, il percorso della mostra ospitata nel complesso museale Santa Maria della Scala e concernente il recupero di oltre quattrocento manufatti ceramici interi, databili nella prima metà del XIV secolo, utilizzati come riempimento di una volta del convento del Carmine a Siena. Il riempimento si componeva prevalentemente di ceramica alternata a gettate di terra e i materiali utilizzati presumibilmente provenivano dalle numerose botteghe di artigiani presenti in questa zona nel Trecento. I manufatti erano destinati a riempire l'intercapedine tra la volta e le pareti degli ambienti che essa sosteneva; al tempo stesso erano sufficientemente leggeri da non gravare eccessivamente con il loro peso. L'intero recupero è stato sottoposto a restauro e costituisce una significativa occasione per cogliere appieno i numerosi aspetti dell'organizzazione della vita quotidiana di Siena nel Trecento. La mostra, curata da Riccardo Francovich e da Marco Valenti dell'Area di Archeologia Medievale dell'Università di Siena, ha visto impegnati il LIAAM (Laboratorio di Informatica Applicata all'Archeologia Medievale), numerosi specialisti nei campi dell'archeometria, delle analisi paleobotaniche, archeozoologiche, ecc
Una cappella privata dei conti Guidi tra XI e XII secolo. Lo scavo della chiesa del castello di Monte di Croce (Pontassieve, FI)
No full textLa rete dei castelli
No full textIl territorio della Provincia di Siena presenta un patrimonio archeologico e architettonico eccezionale. Fra le diverse categorie che articolano questo patrimonio c'è la maglia dei castelli che costituisce in se una ricchezza da promuovere e valorizzare ma sopratutto uno fra gli elementi distintivi più importanti del paesaggio rurale di questa regione. Infatti i villaggi fortificati non rappresentano dei ruderi o mere emergenze architettoniche, ma sopratutto il tessuto vivo che ancora oggi regola e determina parte della formazione e strutturazione del paesaggio culturale. Il presente saggio tenta di fare una resoconto generale sui numeri di questa immensa eredita. Nel farlo si tenta di compiere anche una sintesi relativa alla sua distribuzione spaziale e sull'impatto che il numero ed il peso di questo patrimonio hanno nelle diverse zone della provincia di Siena.The Province of Siena has an exceptional archaeological and architectural heritage. Among the various categories that articulate this heritage is the network of castles which is not only a resource to promote, but above all one of the most important distinguishing features of the rural landscape of this central Italy. In fact, the fortified villages do not represent mere ruins or architectural monuments, but mostly the living pattern that still regulates and determines the formation and structuring of the cultural landscape. This paper attempts to make a general overview on the numbers of this immense heritage. In this effort an account was made on the spatial distribution and the impact of the distribution of this heritage in the different areas of the province of Siena
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
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
