No full textSegesta, Santuario di Contrada Mango: la campagna di scavo 2023 e le nuove scoperte
No full textThis paper illustrates the new ac- quisitions resulting from the excavation campaign conducted by the University of Palermo in 2023 at the Contrada Mango Sanctu- ary in Segesta. The research has focused on the foundations of the temple, extended (towards west) with the section preserved in situ referable to the north wall of the cella. The investigation also fo- cused on the east side of the peribolos, where we assume the access to the sacred area was located, and some elements of a balustrade were brought to light. New acquisitions also result from the un- expected discovery in February 2024 of some finds from the excava- tions at Mango by V. Tusa, which had not been traced during the study of the old excavations published in 2023. Of these materials we mainly illustrate a few items of particular interest: a series of sauroteres and bronze spirals for reinforcing the shaft of spears; a statue of small size and some fragments of marble sculptures; fragments of miniature columns and the frieze of the model temple reconstructed by G. Montali on the basis of other architec- tural elements already traced among the Tusa finds; and some fragments of late 14th-early 15th-century ceramics (mostly of Sciacca production), that document not only the last occupation of the area but also a phase of Segesta life that is almost completely unknown or still blurred in the contours
La rabbia nel mantenimento del legame affettivo
No full textQuesto breve intervento vuole mettere in evidenza alcuni processi osservabili nei legami conflittuali in cui lo “stare insieme” ed il “separarsi “ appaiono due poli tra cui la coppia oscilla nel mantenimento della relazione. Il litigio può sfociare in episodi di violenza ove la rabbia espressa invece che portare alla rottura del legame ne determina il mantenimento. L’osservazione di questi processi necessita nel professionista l’assunzione di una posizione terza in modo tale da poter cogliere non la responsabilità o la colpa dei contendenti ma “in che modo” essi stessi partecipano alla creazione e mantenimento della transazione
Chemical characterization of organic residues on Late Roman amphorae from shipwrecks off the coast of Marsala (Trapani, Italy)
Get PDFOrganic residues were extracted from thirty-three different types of Roman and Late Antique amphorae retrieved from underwater contexts in the custody of the Archaeological Museum “Baglio Anselmi” of Marsala in Sicily. The samples were analysed using GC-MS and 1H NMR, finding biomarkers of plant oils (including saturated and unsaturated fatty acids, alcohols and alkanes present in plant waxes) were identified in seven samples. The biomarkers for Pinaceae spp., used for making pitch, were identified in one sample. The results obtained shed light on the function of different types of North African amphorae, traditionally interpreted as containers for olive oil, wine and fish sauce, presenting new evidence to reassess the system of trade between Sicily and North Africa in Late Antiquity
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
