"Caro Agente" (tra Giovanni Pascoli e Giuseppe Sala Contarini)
No full textIl saggio analizza il carteggio inedito tra Giovanni Pascoli, professore di letteratura latina a Messina e il suo allievo siciliano Giuseppe Sala Contarini, di Girgenti (1876-1942 ), presentato all’inaugurazione del XXIV anno dell’Accademia Pascoliana di San Mauro (15/01/2006), ma ancora pochissimo noto. Si tratta di un archivio, ora acquisito dal Comune di San Mauro e conservato nella Biblioteca di Casa Pascoli, contenente 44 testi epistolari, tra lettere, cartoline postali e cartoline illustrate, scritte da Pascoli all’allievo, tra il 1900 e l’ 8/1/1912, nonché l’autografo di due lezioni universitarie sulle "Bucoliche" virgiliane. Rispetto al regime delle carte disperse dell’epistolario pascoliano il carteggio Pascoli-Sala Contarini risulta prezioso per il carattere intermedio tra pubblico e privato. Non si tratta di uno scambio epistolare costituito da lettere di circostanza e di fredda ufficialità, né di un ambito di rapporti e affetti strettamente familiari (quello testimoniato nella biografia di Maria Pascoli e nella biblioteca di Castelvecchio); le lettere tra maestro e allievo, legate alla semplicità della vita e del quotidiano, ai viaggi, agli spostamenti, agli eventi lieti e tristi degli anni messinesi e insieme al lavoro letterario ed universitario, ci informano su tanti episodi in modo diretto, immediato e impulsivo. Pascoli è in queste lettere professore e maestro tra familiarità e autorevolezza, ritrosie e confidenze, pieno di esigenze e di premure. Il nucleo più consistente delle lettere del 1900 corrisponde alla vicenda editoriale e critica di "Sotto il velame" e s’intreccia con alcune di quelle de "L’Archivio dei «nobili spiriti»", pubblicate da Gianni Oliva. Inoltre il riscontro con le carte e le pubblicazioni del Sala conservate Biblioteca di Castelvecchio ha permesso di dar conto di dati e di elementi del carteggio sfuggiti alla schedatura delle carte epistolari dei corrispondenti di Pascoli (perché nascosti nelle pagine dei libri). Circa le lezioni autografe non mi risultano sinora segnalati altrove ritrovamenti di questo tipo né nell’archivio di Castelvecchio, né nel censimento "Oltre Castelvecchio" di Carla Pisani, né in A. Traina, "Cento anni di Studi pascoliani (Addenda alla Bibliografia del Felcini)" o nelle integrazioni "Bibliografia della critica pascoliana (1997-1999)" e "Bibliografia della critica pascoliana. Integrazioni (1921-1999)" di C. Pisani, e P. Paradisi. Senza entrare nel merito del discorso didattico e critico affidato alle striscie messinesi, il saggio propone un primo confronto tra la loro tipologia testuale e le lezioni dattiloscritte dagli allievi della Scuola Pedagogica di Bologna, conservate a Castevecchio e già ampiamente studiate da Saverio Campanili (1992)
Evaluation of the analytical variability of dipstick protein pads in canine urine
No full textBackground: The dipstick is a first-line and inexpensive test that can exclude the presence of proteinuria in dogs. However, no information is available about the analytical variability of canine urine dipstick analysis. Objectives: The aim of this study was to assess the analytical variability in 2 dipsticks and the inter-operator variability in dipstick interpretation. Methods: Canine urine supernatants (n = 174) were analyzed with 2 commercially available dipsticks. Two observers evaluated each result blinded to the other observer and to the results of the other dipstick. Intra- and inter-assay variability was assessed in 5 samples (corresponding to the 5 different semi-quantitative results) tested 10 consecutive times over 5 consecutive days. The agreement between observers and between dipsticks was evaluated with Cohen's k test. Results: Intra-assay repeatability was good (≤3/10 errors), whereas inter-assay variability was higher (from 1/5 to 4/5 discordant results). The concordance between the operators (k = 0.68 and 0.79 for the 2 dipsticks) and that of the dipsticks (k = 0.66 and 0.74 for the 2 operators) was good. However, 1 observer and 1 dipstick overestimated the results compared with the second observer or dipstick. In any case, discordant results accounted for a single unit of the semi-quantitative scale. Conclusions: As for any other method, analytic variability may affect the semi-quantitation of urinary proteins when using the dipstick method. Subjective interpretation of the pad and, to a lesser extent, intrinsic staining properties of the pads could affect the results. Further studies are warranted to evaluate the effect of this variability on clinical decisions
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

No full textDispelling 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
