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
La Cartografia nei suoi molteplici aspetti, reali ed immaginari. 8 aprile-21 maggio 2005. Mostra in occasione della riapertura al pubblico del Museo Universitario del Dipartimento di Scienze della Terra "Gemma 1786"
No full textLa riapertura al pubblico del Museo Universitario del Dipartimento di Scienze della Terra, rinominato "Gemma 1786", è stata un'occasione per presentare al pubblico in una veste rinnovata le collezioni museali di minerali, rocce e carte.Le carte sono espressione dell'uomo e della sua necessità di conoscere il territorio in cui vive. Le carte raccontano quindi dell'uomo e del territorio.La mostra, realizzata in collaborazione con l'Archivio Storico del Comune di Modena e la Biblioteca d'Arte L. Poletti di Modena, ha voluto mettere a confronto rappresentazione cartografiche antiche e recenti del territorio modenese con rivisitazioni artistiche dell'artista Giovanni Valbonesi realizzate con tecniche a collage
Very late relapse in an HCV genotype 3-infected patient treated with direct-acting antivirals (DAA)
No full textVariations 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
Daily bathing with 4% chlorhexidine gluconate in intensive care settings: a randomized controlled trial
No full textObjectives: To investigate whether daily bathing with a soap-like solution of 4% chlorhexidine (CHG) followed by water rinsing (CHGwr) would decrease the incidence of hospital-acquired infections (HAI) in intensive care settings. Methods: Randomized, controlled trial; infectious diseases specialists were blinded to the intervention status. All patients admitted to the Intensive Care Unit (ICU) and to the Post-operative Cardiosurgical Intensive Care Unit (PC-ICU) of the University Hospital of Perugia were enrolled and randomized to the intervention arm (daily bathing with 4% CHGwr) or to the control arm (daily bathing with standard soap). The incidence rate of acquisition of HAI was compared between the two arms as primary outcome. We also evaluated the incidence of bloodstream infections (BSI), central-line-associated BSI (CLABSI), ventilator-associated pneumonia (VAP) and catheter-associated urinary tract infections (CAUTI), and 4% CHGwr safety. Results: In all, 449 individuals were enrolled, 226 in treatment arm and 223 in control arm. Thirty-four individuals of the 226 (15%) and 57 (25.6%) suffered from at least an HAI in the intervention and control arms, respectively (p 0.008); 23.2 and 40.9 infections/1000 patient-days were detected in the intervention arm and control arm, respectively (p 0.037). The incidence of all bloodstream infections (BSI plus CABSI) was significantly reduced in the intervention arm (9.2 versus 22.6 infections/1000 patient-days, p 0.027); no differences were observed in the mortality between the two arms. Conclusions: Daily bathing with 4% CHGwr significantly reduced HAI incidence in intensive care settings. ClinicalTrial. gov registration: NCT03639363.

Il satiro danza su un intaglio in corniola da Muccia
No full textA new cornelian intaglio found in the excavation at Muccia (MC) shows a young dancing satyr. The vivid rendering
of the body and fine characterization indicate a well known specimen and the classicizing style approaches that of the
selected series realized in Roman workshops at the end of the first century B.C. and the beginning of the first century A.D. The cornelian increases the evidences of Roman productions in the ancient Marche region, where most of engraved gems
and finger rings preserved in the National Archaeological Museum of Ancona date to late-classical and Hellenistic period.
The findings from the celtic necropolis of Filottrano, Osimo and Montefortino di Arcevia give important information in order
to identify imports from Etruria, South Italy and North Greece next to local productions; in order to recognize phases, ways
and dynamics of the artefacts distribution and use during almost two centuries. The findings from the Ancona Hellenisticroman
graves increase the knowledge, including the territory in a network of the Aegean trades
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
