Scrittore stoico anonimo, Opera incerta (PHerc. 1020), coll. 104-112. Edizione, introduzione e commento
No full textPHerc. 1020 (SVF 2. 131 = FDS 88) è uno dei sette papiri di sicura o probabile paternità stoica conservati nella collezione ercolanese. Esso è privo di subscriptio, per cui dell’opera in esso conservata si ignorano autore e titolo. Svariati elementi sembrano corroborare la tesi, risalente a Hans von Arnim, che PHerc. 1020 contenga parte di un’opera risalente a Crisippo o a uno dei suoi immediati successori. A favore della paternità crisippea vengono qui forniti nuovi argomenti, che si aggiungono a quelli già addotti da von Arnim, Pohlenz e Keil. Per quanto riguarda il contenuto del libro, non siamo autorizzati a concludere né che esso equivalesse a uno scritto di tipo esclusivamente morale, piuttosto che logico o epistemologico, né che trattasse unicamente del sapiente stoico. Al contrario, dall’esame puntuale del testo, volto in particolare a comprenderlo in relazione alle altre numerose testimonianze sullo Stoicismo antico in nostro possesso, è emerso che esso presentava una singolare compenetrazione di logica, etica ed epistemologia. Facendo uso di nuove metodologie in campo papirologico, i due editori hanno ricostruito per la prima volta l’anatomia del rotolo e la sequenza dei frammenti e hanno ristabilito il testo con nuovi criteri editoriali basandosi sull’autopsia del manoscritto originale. Il presente lavoro consiste in una nuova edizione critica delle ultime otto colonne del papiro (coll. 104-112 Alessandrelli-Ranocchia), le meglio conservate e le uniche sinora edite dagli studiosi, e si inquadra nell’edizione complessiva di PHerc. 1020 programmata nell’ambito del progetto ERC Starting Grant 241184-PHerc finanziato dalla Commissione Europea (FP7, Ideas, www.pherc.eu)PHerc. 1020 (SVF 2. 131 = FDS 88) is one of the seven certain or probable Stoic papyri of the Herculaneum collection. Since the papyrus has no subscriptio, the author and the title of the work contained in it are unknown. Several elements seem to corroborate Hans von Arnim’s thesis that PHerc. 1020 hands down a work by either Chrysippus or one of his immediate successors. New arguments are advanced here in favour of this authorship beside those formerly adduced by von Arnim, Pohlenz and Keil. As far as the book’s content is concerned, we are not allowed to conclude that it was merely ethical, rather than purely logical or epistemological, nor that it only focused on the Stoic sage. On the contrary, from a detailed exegetical analysis and a comparison with the other evidence on Early Stoicism available to us it emerges that the work displayed a unique combination of ethics, logic and epistemology. By using new methods for the reading and editing of Herculaneum papyri, the editors have reconstructed for the first time the anatomy of the roll and the sequence of the fragments, while also establishing the Greek text on the basis of personal inspection of the original manuscript. This study is a new critical edition of the last eight columns of the papyrus (coll. 104-112 Alessandrelli-Ranocchia) – the best preserved columns and the only ones to have been studied by scholars so far – and constitutes the first part of the comprehensive edition of PHerc. 1020 included in the Project ERC Starting Grant 241184-PHerc funded by the European Commission (FP7, Ideas, www.pherc.eu)

No full textP.Herc. 1020, transmitting an Early Stoic text (probably by Chrysippus), was unrolled between 1803 and 1804 and is preserved in 13 pieces, which have come to us in poor condition. One piece has been proven not to belong to this papyrus on palaeographical grounds. The stratification of the pieces ranges from absent to severe. The original order of fragments was upset after some pieces were hung on the walls of the Officina dei papiri around 1865 and subsequently taken down at the beginning of the 20th century. It has been reconstructed both by measuring the 'voluta' of each piece and on the basis of Hayter's numeration either legible on the 'cartoncino' on which some pieces are fixed or inferable from the 'disegni'. The impossibility of identifying with certainty the text layout of the outer pieces of the roll because of the presence of multiple layers in them make it difficult to estimate with precision the length of the lost portions between them. In addition, the lengthwise compression of the papyrus roll permits only an approximation of its original length and total number of columns. As far as the preserved text is concerned, in addition to the 8 columns previously edited by Hans von Arnim, 18 inedited columns have been read and transcribed so far. A new critical edition of the book is currently being prepared within the framework of the project ERC Starting Grant 241184-PHerc (European Commission, FP7, 'Ideas')
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
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
