La città del vescovo - Spazio XII
No full textLa guida al nuovo allestimento del MArE - Museo Nazionale Archeologico di Egnazia ‘Giuseppe Andreassi’ è pensata con diversi livelli di approfondimento, come introduzione esplicativa per gli studiosi e al contempo come supporto utile alla visita per i non addetti ai lavori. In questo volume, il capitolo di G. Mastrocinque sulla città tardoantica inquadra i reperti in allestimento nel contesto degli spazi più significativi indagati con le ricerche più recenti condotte dallo stesso autore e mostra, di settore in settore, il cambiamento del paesaggio urbano a partire dalla fine del IV secolo d.C., legato anche alla presenza di una sede vescovile autorevole
Localizzazione S1 di Herpes Zooster: un raro caso di ritenzione urinaria.
No full textDonna di 46 anni con ritenzione urinaria acuta e stipsi. Presentava piccola vescicola sul dorso del piede sinistro quale unica manifestazione di localizzazione di virus Herpes Zooster a livello sacrale S1. Viene riportato l'esame urodinamico e le risultanze dei test sierologici seriati specifici per l'infezione da virus Varicella Zooster. La paziente è guarita a seguito di terapia specifica con Acyclovir. Il caso riportato dimostra che anche il segmento sacrale S1 contribuisce al controllo della dinamica minzional
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
Coding capacity of complementary DNA strands
No full textA Fortran computer algorithm has been used to analyze the nucleotide sequence of several structural genes. The analysis performed on both coding and complementary DNA strands shows that whereas open reading frames shorter than 100 codons are randomly distributed on both DNA strands, open reading frames longer than 100 codons ("virtual genes") are significantly more frequent on the complementary DNA strand than on the coding one.These "virtual genes" were further investigated by looking at intron sequences, splicing points, signal sequences and by analyzing gene mutations. On the basis of this analysis coding and complementary DNA strands of several eukaryotic structural genes cannot be distinguished. In particular we suggest that the complementary DNA strand of the human e{open}-globin gene might indeed code for a protein. © 1981 IRL Press Limited
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
L'area forense di Forum Sempronii (Fossombrone, PU)
No full textForum Sempronii was founded in the 2nd century BC, probably by Caius Sempronius Gracchus, on a vast terrace of the River Metauro, in a site populated in Pre-Roman times. After flourishing and evolving between the 1st and the 2nd century AD, the city declined steadily in the mid-late Imperial Age. The excavations carried out since 1974 have brought to light important elements for the understanding of the urban planning of the city, which is based on a programmatic regular plan, with the via Flaminia as the large decumanus maximus. A fundamental contribution has recently been given thanks to the use of aerial photos, satellite imagery and geophysical prospecting in significant areas: in addition to the discovery of an amphitheatre, in particular, the significant area of the Forum to the North of the Via Flaminia has been identified, with three temples and porches surrounding a large square. Outside the eastern boundary of
the forum a third structure is now identified as the Augusteum of Forum Sempronii, still paved with rectangular slabs of grey marble. After meticulous archival research, we are now able to prove both that the bronze statue of a winged Victory kept at the German Museum of Kassel was recovered in 1660 inside this significant building. We can also reasonably speculate that most of these public buildings are the result of an imposing urban and architectural
reorganization of the municipium during the Augustan period
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
