Indagini archeologiche subacquee nella laguna sud di Venezia: il casone della Rivola Vecchia e un nuovo sito presso il Canale Bastia
No full textIndagini archeologiche subacquee condotte nel 2010 e 2011 presso il Canale Bastia, nella laguna sud di Venezia, hanno consentito di esaminare i resti di due siti ora completamente sprofondati sotto il livello di medio mare. Si tratta del "casone" della "Rivola Vecchia", un caratteristico edificio abitativo e funzionale nato in funzione delle attività di pesca e caccia lagunare, con una lunga continuità d'uso, partendo almeno dal XVI secolo e fino a tutto il XIX. Non lontano da questo si è rinvenuto un secondo sito, riferibile sempre a un impianto funzionale allo sfruttamento delle risorse lagunari, databile tra il XIV e il XV secolo. Entrambi i siti risultano molto interessanti anche per comprendere le modificazioni geomorfologiche e ambientali avvenute nella laguna sud negli ultimi cinque/sei secoli, con importanti ricadute sull'insediamento e lo sfruttamento di questo territorio.Underwater archaeological research carried out in 2010 and 2011 near Bastia canal, in the southern area of Venice lagoon, allowed to investigate the remains of two sites now collapsed under the medium sea level. It is the "casone" (lagoon dwelling) named of “Rivola Vecchia”, a lagoon dwelling born in relation with fishing and hunting economy in the lagoon, with a long-lasting life,
from 16th to the 19th Century. Near this site a second one was discovered, dating back to 14th - 15th Century. Both sites are very interesting to understand the geomorphological and environmental modifications of the southern Venice lagoon in last five-six centuries, with important
consequences on human settlement an environment exploitation
Indagini archeologiche nell’Arsenale di Venezia, tese della Novissima, 2014-2015
No full textVengono presentati i risultati delle indagini archeologiche condotte nel 2014 e 2015 in assistenza alle opere di rifacimento della banchina nord della Darsena Novissima dell'Arsenale di Venezia. Le indagini, condotte si a terra che in acqua, hanno consentito di riconoscere i resti delle strutture dei ricoveri per le navi (tese) per una fase cronologica compresa tra la fine del XV secolo (inizio costruzione della Novissima) e il XVII secolo.The results of the archaeological investigations conducted in 2014 and 2015 in assistance to the restoration works of the north quay of the Darsena Novissima in the Venice Arsenal are presented. The investigations, carried out both ashore and underwater, have made it possible to recognise the remains of the structures of the shelters for the ships ("tese") of a chronological phase between the end of the 15th century (beginning of construction of the Novissima) and the 17th century
Un manufatto monossile di età romana a Lio Piccolo, Laguna di Venezia
No full textIn un terreno lungo la sponda del canale Rigà, presso l’abitato di Lio Piccolo nella laguna nord di Venezia, è stato individuato nel 2015 un manufatto monossile di quercia, in giacitura secondaria, ma rinvenuto in contesto subacqueo in occasione dei lavori di risistemazione della vicina chiavica idraulica situata sulla riva del canale. Il rinvenimento si colloca in un’area lagunare interessata da importanti evidenze archeologiche di epoca romana. Le analisi 14C hanno evidenziato una datazione del manufatto tra il I e il II sec. d.C., coerente con la quota di giacitura originaria del reperto e con i materiali rinvenuti contestualmente ad esso, riferibili ad epoca romana. L’analisi tipologica e il confronto con altri reperti simili rinvenuti in laguna nord, suggeriscono di identificare il manufatto non con uno scafo, ma come una condotta idraulica, verosimilmente funzionale alla regimazione delle acque tra bacini idrici e/o al funzionamento di impianti produttivi.An artifact made from a single excavated oak trunk (monoxylon) was identified in 2015 in the northern Venice lagoon, in the countryside along the Rigà canal bank, near Lio Piccolo small village. The artefact is now in a not original location, but it was fond underwater during the redevelopment works of the nearby hydraulic sewer located on the canal side. The discovery is located in a lagoon area characterised by important Roman Age archaeological evidences. The 14C analysis revealed for the artifact a date between the 1st and 2nd century AD, consistent with the original lying depth of the artefact and with the contextual finds, which can be attributed to the Roman Age. Typological analysis and comparison with other similar artifacts found in the northern lagoon suggest identifying the artifact not as a hull, but as a hydraulic conduit, probably functional for the regulation of water between reservoirs and/or for the operation of production facilities
Strutture arginali antiche e paesaggio lagunare presso l'isola di Sant'Erasmo, laguna di Venezia.
No full textNell’ambito di una campagna di indagini archeologiche subacquee nei bassifondi a nordovest dell’isola di Sant’Erasmo, nella laguna nord di Venezia, sono stati identificati diversi siti riconducibili a strutture arginali antiche, in vari casi a quelle note localmente come ‘argini-strada’, giacenti
sotto potenti strati di sedimento prevalentemente limoso. L’attribuzione a questa tipologia deriva dall’incrocio dei dati raccolti nelle due fasi delle indagini: il grande sviluppo longitudinale e la larghezza più o meno costante delle anomalie rilevate con la sonda metallica manuale e la natura delle stesse, costituita da pali lignei e accumuli di materiali di reimpiego, fondamentalmente laterizi e anfore, messi in luce con l’apertura di piccoli saggi di scavo. Si rileva una costante discrepanza tra la datazione dei materiali, tutti riferibili ad epoca romana, e quella dei pali lignei, che riconduce ad epoca tardo-antica ed altomedievale. Le evidenze riscontrate contribuiscono a definire il paesaggio lagunare antico, in una zona prossima al litorale.Within a campaign of underwater archaeological investigations in the shallows to the north-west of the island of Sant'Erasmo, in the northern lagoon of Venice, several sites have been identified that can be traced back to ancient embankment structures, in several cases to those known locally as ‘road-embankments’, lying under very thick layers of predominantly silty sediment. The attribution to this typology derives from merging the data collected in the two phases of the investigations: the large longitudinal development and more or less constant width of the findings detected with the hand-held metal probe and the nature of the same finds, consisting of wooden piles and accumulations of reused materials, basically bricks and amphorae, brought to light with the opening of small excavation tests. There is a constant divergence between the dating of the materials, all referable to the Roman period, and that of the wooden piles, which leads back to the late antique and early medieval periods. The evidence found contributes to defining the ancient lagoon landscape in an area close to the littoral zone
Il relitto del Molo Sud presso il porto di Malamocco (Venezia)
Full text linkThe paper is dedicated to the complicated underwater archaeological excavation, displacement, temporary lifting, photogrammetric and 3D laserscanner documentation, final protection of the 'wreck of the south pier', at the Malamocco inlet, Venice lagoon. The wreck is attributable to a brig carrying coke coal. The shipwreck dates back to the middle of the 19th century.Il contributo è dedicato ai complessi interventi di scavo archeologico subacqueo, spostamento, sollevamento temporaneo e protezione definitiva del "relitto del molo sud", presso la bocca di porto di Malamocco, laguna di Venezia. Il relitto è riferibile a un brigantino che trasportava carbone coke. Il naufragio si data intorno alla metà del XIX secolo
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
