Advanced diagnostic plan applied to the Royal Villa in Naples
No full textTo achieve adequate restoration project, the moment of choice of the type of intervention is a very delicate phase that necessarily involves a thorough understanding of the asset in all its aspects, as the location, the history, the architecture, the state of preservation, the pathologies causing the degradation, the degradation in itself, the analysis of constituent materials. The set of all that can be investigated on a product (cultural), to obtaining important information for subsequent maintenance, conservation and/or restoration actions, is what is called a diagnostic plan. In this case it was applied directly on a monument of national importance: the Royal Villa in Naples (today the Municipal Villa). The analysis were performed in situ and in the laboratory (SEM-EDS) on samples taken directly at the Villa, which allowed the creation of a series of analytical cards, containing digital data, required for the selection of expense future of intervention
Gruppi terapeutici e disturbi dell'alimentazione. L'omogeneità come elemento trasversale alle dinamiche di gruppo? Una rassegna empirica
No full textEffect of air pressure on the electro-generation of H2O2 and the abatement of organic pollutants in water by electro-Fenton process
Full text linkThe electro-generation of H2O2 and the abatement of the model organic pollutant Acid Orange 7 (AO7) in water by an electro-Fenton process were perfomed under moderate air pressures (up to 11 bar) for the first time. An increase of the pressure gave rise to a drastic enhancement of the concentration of hydrogen peroxide. At 11 bar, the reduction of oxygen gave rise at a graphite cathode to a concentration of H2O2 of about 12 mM, about one order of magnitude higher than that achieved at atmospheric pressure, as a result of mass transport intensification. Similarly, for electro-Fenton, a drastic increase of the abatement of TOC was achieved upon increasing the air pressure. The effect of the current density was also investigated in detail
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
Un metodo per l’identificazione della provenienza: il tempio di Athena a Kamarina
No full textLa raccolta di informazioni relativa ai monumenti dell’antichità necessita di una particolare cura e attenzione soprattutto per la rarità oltre che per l’importanza dell’opera. Appare evidente quindi che le informazioni che si riescono ad acquisire acquistano un valore di rappresentatività, per cui è necessario agire in modo da renderle facilmente trasferibili e utilizzabili in contesti similari. L’analisi di una frazione di cella del tempio di Athena situato nel parco archeologico di Kamarina a Ragusa, in Sicilia, ha permesso di acquisire dati ed informazioni di notevole importanza sul monumento, che si configurano come una base conoscitiva di utile supporto ai fini della predisposizione di un programma di conservazione da utilizzare inoltre come emblematico riferimento per altri monumenti simili appartenenti alla Sicilia. Nello specifico è stata svolta una caratterizzazione mineralogica del litotipo prelevato da quello che ancora resta della cella del tempio di Athena ed in parallelo è stata svolta la medesima caratterizzazione su campioni di roccia prelevati dalla cava di Punta Braccetto identificata come probabile cava di approvvigionamento.
L’obiettivo dello studio è consistito nell’applicazione di una procedura metodologica che ha permesso di mettere in comparazione i dati di caratterizzazione relativi ai campioni prelevati sul monumento con quelli prelevati dalla cava, indicata in letteratura come quella utilizzata per prelevare il materiale per realizzarne la costruzione.
Nel caso del tempio di Kamarina lo studio, corredato da una contestualizzazione storico- geografica e da un dossier fotografico, ha consentito di verificare che i materiali utilizzati per costruire il tempio provenivano effettivamente dalla cava di Punta Braccetto situata poco distante dal monumento, a conferma di quanto riportato dalle fonti storiche
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
