Heraclitus in verse : The poetic fragments of Scythinus of Teos
No full textThe fragmentary state in which Heraclitus’ book has survived makes it necessary to use secondary sources to shed light upon some aspects of Heraclitean philosophy. One of these sources is the poetical version of Heraclitus composed by Scythinus of Teos (5th-4th century BC). Only two fragments of this work still survive. The first one describes Apollo tuning his lyre by “taking together the beginning and the end”, while holding the light of the sun as plectrum. This image reveals to be an original synthesis of Heraclitus’ philosophy. The second fragment, preserved by Stobaeus in an unexpected and corrupt prose version still maintaining traces of metre, provides a unique definition of χρόνος, a concept which does not occur in Heraclitus’ fragments. Several scholars have tried to restore the original metrical form. Wilamowitz’s proposal in trochaic tetrameters seems to be the most consistent and philologically reliable. Scythinus describes Time as the first and last of all things, which goes forward to find itself on the opposite way – yesterday and tomorrow are therefore interchangeable. Such a definition shows to be very close to the content of many surviving Heraclitean fragments. Since we know that Scythinus just transposed the content of Heraclitus’ book into poetry, we must conclude that this fragment coincides with the Heraclitean definition of χρόνος. On this basis, it is possible to bring to light strong analogies between Heraclitus’ own thought and Orphic doctrines

Aeolica Maasiana : le postille di Paul Maas a Saffo e Alceo
No full textPaul Maas (1880-1964) è stato uno dei filologi classici più importanti del XX secolo. Fine metricologo e teorico della critica del testo, aveva la preziosa abitudine di postillare fittamente i volumi della sua biblioteca personale. Molti di questi volumi si trovano oggi presso l’Università degli Studi di Milano e conservano numerose riflessioni e proposte testuali tuttora inedite. In particolare, sono conservati a Milano tutti i volumi di Maas dedicati a Saffo e Alceo attualmente noti. In anni in cui lo studio della lirica eolica è stato ravvivato da scoperte papiracee e nuove edizioni critiche, questo volume intende offrire agli studiosi un’ampia selezione commentata delle postille maasiane relative ai due poeti. In appendice è pubblicata una cartolina di Paul Maas ad Achille Vogliano su un frammento di lirica eolica
La nutrice di Saffo in P.Oxy. 2289 e i paralleli omerici nel «Carme dei fratelli»
Full text linkSecondo l’ipotesi avanzata da Anja Bettenworth, nel cosiddetto Carme dei fratelli Saffo si rivolge probabilmente a una nutrice anziché alla madre. Alla luce di ciò, il termine omerico μαῖα potrebbe essere recuperato nel frammentario adonio di P.Oxy. 2289. Inoltre, i paralleli omerici riscontrabili nel carme di Saffo inducono a pensare che questa traesse ispirazione da alcuni passaggi dell’Odissea, cosa che sembra giustificare tale integrazione
Deep Space Autonomous Orbit Determination Using CCD
No full textIn this paper an algorithm for orbit determination in deep space using only measurements of attitude and of line of sight of known celestial bodies is presented. Measurements are then processed using two different filters reconstructing part or the entire state vector: a batch least squares filter and a combination of batch and Kalman filter. The strategy and the effectiveness of the two filters are compared on two sample cases of interplanetary trajectory toward Mercury (inner part of the solar system) and toward Jupiter (outer part of the solar system)
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
