“Ci sono più cose in cielo e in terra...” Due metodologie diverse per investigare il passato: il Castello Nuovo di Sciacca tra storia e archeologia
Full text linkLa storia di Sciacca e del Castello Nuovo, ricostruita sulle fonti documentarie, riceve nuova luce dalle indagini condotte dalla Soprintendenza di Agrigento nel butto del castello, che ha restituito importanti testimonianze di cultura materiale. Il contributo, attraverso la lettura sinottica dei dati archeologici ed archivistici, offre un quadro della vita quotidiana al castello tra il XIV ed il XVI secolo, quando Sciacca con il suo caricatore riveste un ruolo di primo piano nel commercio mediterraneo.The history of Sciacca and Castello Nuovo documented by archival sources and further enriched by the researches conducted by Soprintendenza of Agrigento is in the dump of the castle, which has yielded important evidence for its material culture. The paper proceeds through the synoptic reading of the archaeological and archive data, offers a pattern of daily life at the castle from the 14th to the 16th century, when Sciacca with its port plays a leading role in Mediterranean trade
Modelli pompeiani ad Agrigentum. Una nuova lettura della Casa IA-IB del Quartiere ellenistico-romano
No full textA partire da una lettura della geometria dell'impianto della Casa IA-IB del Quartiere ellenistico-romano di Agrigento si propone una diversa suddivisione dei lotti originari dell'abitazione e un'ipotesi sulla percorrenza interna (da Nord piuttosto che da Ovest, come sempre sostenuto) che fa emergere l'analogia con case a doppio atrio e peristilio di area campana, prima fra tutte la Casa del Fauno di Pompei che riflette, pur con le dovute differenze qualitative, la stessa logica distributiva e la stessa sequenza, anche in termini cronologici, delle trasformazioni. Riguardo alla Casa IA si confuta la tradizionale ipotesi che ne faceva un'abitazione indipendente, in gran parte rimasta obliterata da costruzioni moderne proponendo di vedervi un originario hortus di pertinenza della Casa IB, successivamente monumentalizzato con l'inserimento di un grande peristilio
La crisi vista da un archeologo. Alcune considerazioni sulla situazione attuale dei beni culturali
No full textIl contributo esamina la situazione dell'archeologia siciliana negli anni della crisi, non solo dal punto di vista dell'assenza di adeguati finanziamenti, quanto dal punto di vista della politica di tutela e valorizzazione dei beni culturali e dell'investimento nella formazione. Il punto di svolta in negativo è individuato nella legge 40 del 2000 che abolì i ruoli tecnici nell'amministrazione dei beni culturali. Perché dai beni culturali si abbia un ritorno economico è necessario investire in maniera sinergica sul beni culturali stessi, sulle infrastrutture e sulla promozione del turismo
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
