Carteggio Domenico Comparetti Gherardo Nerucci
Negli anni settanta Sebastiano Timpanaro invitò i filologi a indagare la corrispondenza di Comparetti con Nerucci, come fonte per la ricostruzione della prima fase comparettiana.Il Carteggio Domenico Comparetti-Gherardo Nerucci non solo realizza quel voto, ma apre nuovi e significativi scenari che fanno luce sulla situazione della filologia classica italiana nella seconda metà dell'Ottocento,sui suoi rapporti con le discipline linguistiche e archeologiche,sul confronto, infine,con la scienza europea, in particolare con le grandi scuole sviluppatesi in area germanica

Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Evaluation of benzene exposure in petrol pump attendants and in mechanics by urinari trans, trans-muconic acid (t, t-MA) determination
Occupational exposure to benzene in petrol pump attendants and in mechanics was studied by examining the benzene content in both the air breathed and in the urinary metabolite trans,trans-muconic acid (t,t-MA).
Thirty petrol pump attendants and thirty mechanics (as exposed workers) and thirty adult male office workers
(as non exposed workers) were involved in the study. Measures were taken at the begin and at the end of the
working shifts. The benzene concentrations in the breathing air samples varied from 2 to 88 μg m3 , lower than
the EU acceptable limit for occupational environment. The average urinary t,t -MA in the petrol pump
attendants at the begin and at the end of the working shifts ranged between 133 ± 69 and 255 ± 174 μg g-1
creatinine and in the mechanics between 204 ± 139 and 300 ± 211 μg g-1 creatinine, respectively. In all the
participants the mean levels of urinary t,t-MA at the end of the working shifts were significantly higher than
those at the beginning. In the exposed workers mean levels of urinary t,t-MA were significantly higher than in
those of the non-exposed workers. The influence of the smoking was demonstrated by the urinary t,t-MA
levels in smoking non-exposed subjects
Variations on the Author
“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
We 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
We 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
