No full textIl volume raccoglie diversi contributi presentati nell’ambito della sessione del convegno “Relitti e commercio romano nel Mediterraneo occidentale in epoca romana” (12aRoman Archaeology Conference, Sapienza - Università di Roma, 17 marzo 2016).
Il tema delle reti commerciali and della loro organizzazione, che costituisce una parte del progetto Immensa Aequora (www.immensaaequora.org), è stato affrontato da archeologi e storici.
Il contributo di André Tchernia analizza la valenza degli studi statistici sui relitti antichi; Elio Lo Cascio e Marco Maiuro si concentrano sulla relazione che intercorre tra i dati ottenuti dallo studio dei relitti e il volume del commercio marittimo nel Mediterraneo antico; l’articolo di Giuseppe Camodeca, Stefano Iavarone e Michele Stefanile mira a fornire alcune novità dallo studio prosopografico in Campania; Sandrine Élaigne e Séverine Lemaître si occupano degli indici di commercializzazione dei contenitori ceramici ad Alessandria durante il periodo ellenistico e il primo Impero; il lavoro di Luc Long e Giorgio Spada è incentrato sul commercio di metalli e marmo alla foce del Rodano - località “Saint-Ferréol”; il contributo di Simon Luca Trigona e Daniela Gandolfi intende presentare le recenti scoperte subacquee in Liguria; il lavoro preliminare di Francesco Marco Paolo Carrera, Alessandro Porqueddu e Claudia Giarrusso è relativo alla ripresa delle ricerche sul relitto di Spargi; l’articolo di Carlo Beltrame è incentrato sui relitti che trasportavano marmo; infine, il contributo di Nicolas Garnier e Gloria Olcese presenta i risultati delle analisi dei contenuti condotte su alcune anfore dei relitti eoliani Filicudi F e Secca di Capistello
Variations on the Author
No full text“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
Relitti di età medievale e moderna lungo le coste del Salento: lo stato delle ricerche
No full textNel corso degli ultimi anni le attività di ricerca del gruppo di lavoro afferente al Dipartimento Beni Culturali dell’Università del Salento hanno considerevolmente incrementato la banca dati del sistema informativo della Carta Archeologica Subacquea. In particolare, risultano di notevole rilevanza alcuni relitti di età medievale e moderna, peraltro rinvenuti in ambiente di spiaggia, alati o arenatisi, ed attualmente giacenti tra -1.5 e -2.5 m; elemento comune è la valenza di indicatori di variazioni relative del livello del mare e del profilo costiero, da comparare con i modelli eustatici più recenti, come la curva di Lambeck.
Il relitto del Bacino Grande di Porto Cesareo (Le), scoperto nel 2010, è stato datato tramite C14 (CEDAD – Università del Salento) tra fine del IX e X secolo; alcune peculiarità costruttive rimanderebbero al Mediterraneo orientale, ponendo quindi stimolanti quesiti sulla possibile provenienza del natante e sulle influenze culturali che denota.
Un tassello significativo per la conoscenza dell’importante sito archeologico rappresentato dalla baia di Torre Santa Sabina (Br) è costituito dal presunto relitto postmedievale Torre S. Sabina 5, individuato già nel 1999 a seguito di una operazione congiunta dell’ICR e del Museo Provinciale di Brindisi, ma oggetto di un nuovo intervento di scavo dell’Università del Salento nel 2010. Lo studio di vari reperti, talora attribuiti allo stesso scafo, mira a precisarne entità e cronologia.
Il relitto delle Cesine (Le) è una grossa imbarcazione di età moderna (XVIII – XIX secolo) molto ben conservata (oltre 25 m in lunghezza) con spesso fasciame, ordinate grosse e serrate e lamina di rame di rivestimento, a cui sono presumibilmente riferibili due cannoni poco distanti. Analogo ad esso è il relitto di Torre Rinalda (Le), alcuni chilometri più a nord, nella cui area poppiera si è individuata una serie di barilotti contenenti polvere da sparo, palle di moschetto e sostanze antidetonanti.
I processi formativi di questi relitti trovano un prezioso riferimento in un atto notarile degli inizi dell’Ottocento, che attesta lo scampato naufragio di una nave salpata da Trieste ed incagliatasi proprio nelle acque antistanti le Cesine

Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
Geochemical signatures of intense episodic anaerobic oxidation of methane in near-surface sediments of a recently discovered cold seep (Kveithola trough, NW Barents Sea)
No full textAt cold seep environments, the detection of large 34S enrichments within bulk sulphide minerals has been frequently
used as a proxy to infer the vertical migrations of the sulphate-methane transition zone (SMTZ).
Processes related to the oxidative part of the sulphur cycle can alter the original stable sulphur isotope composition
(δ34S) of the solid sulphur phases, in particular at the sediment-water interface. Identification of paleo
and present positions of methane fronts in the sedimentary records requires the use of multiple geochemical
proxies. Authigenic enrichment of Mo has been demonstrated to represent a valid and durable tracer of the past
SMTZ depth fluctuations and of the intensities of the related methane seepages. This study is based on two
closely-spaced short cores collected from the Main Drift of the Kveithola trough, a glacially-carved depression
located in northwestern Barents Sea. Active fluid seepage has been recently reported in this area and a gas flare
was specifically observed in proximity of the sampling sites where the cores object of our study were retrieved. In
order to collect evidences of the possible occurrence of anaerobic oxidation of methane (AOM) at the sedimentwater
interface of the investigated area and infer the entity of the associated methane flux, we combined the
analyses of reduced sulphur species δ34S, total organic carbon and redox-sensitive elements. The negative δ34S
values within the extracted solid sulphur phases (up to −49.1‰ for pyritic sulphur) show that organoclastic
sulphate reduction (OSR) coupled with disproportionation of sulphur intermediates are the only active processes
in the near-surface sediments. However, moderate to strong enrichments of Mo detected in the relatively organic
carbon poor intervals of both cores and the lack of concurrent enrichments of Co, Cu, Ni, V and Zn, usually
associated to OSR-dominated environment, suggested that the sulphidic conditions favouring the Mo enrichments
were produced by AOM. Therefore, we infer that high methane flux events characterized the drift area of
the Kveithola, occasionally moving upward the SMTZ and thus inducing intense AOM in proximity of the sediment-
water interface of this part of the trough. Our results confirmed the validity of sedimentary Mo as an
indicator of the occurrence and intensity of past methane seepages
John F. Kennedy telegram to Roosevelt
No full textJersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works
Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either

Mapping the Discipline of the Olympic Games An Author-Cocitation Analysis
No full textThe authors conducted an author cocitation analysis on prominent authors writing about the Olympics during the 1990s. Author cocitation is an established bibliometric technique that can be used to measure the relative similarities of topics written about by the cited authors. This enables a visual representation of the “intellectual space” of the discipline, in this case the Olympics, to be created for the period under review. So core and peripheral research areas are identified, along with their major contributors. The representation appears as a two-dimensional cluster-enhanced map. Subject expertise was then applied to the results to place labels on the generated clusters of authors and their topics
