Before and After the Commentators: An Essay in Periodization.
No full textL'articolo considera il significato storico e filosofico dei commentatori neoplatonici di Aristotele. Gli autori situano il recente Sourcebook sui commentatori edito da Richard Sorbji in un contesto più ampio, che include il contributo dei commentatori nella formazione della filosofia tardo-antica e la loro posterità nella tradizione filosofica islamica. Dopo una sezione introduttiva (1) sullo stato attuale della ricerca in questo ambito, gli autori affrontano i temi seguenti: (2) Plotino, i commentatori e lo sviluppo del pensiero tardo antico; (3) il Sourcebook e la filosofia islamica. Riccardo Chiaradonna è co-autore della sezione (1) e autore della sezione (2), dove la ricezione dei trattati di scuola aristotelici è presentata come una caratteristica fondamentale nella transizione dalla filosofia post-ellenistica a quella tardo-antica. Plotino ha un ruolo cruciale in questo processo e l'assimilazione neoplatonica dei trattati di Aristotele non avrebbe avuto luoro senza il suo contributo.This article considers the historical and philosophical significance of the Neoplatonic commentators on Aristotle. The authors set Richard Sorabji's recent Sourcebook on the commentators within a wider backgroung, which covers the commentators' contribution in the shaping of late antique philosophy and their posterity in the Islamic philosophical tradition. After an introductory section (1) regarding the current status of research in this area, the authors tackle the following issues: (2) Plotinus, the commentators and the development of late antique thought; (3) the Sourcebook and Islamic Philosophy. Riccardo Chiaradonna is co-author of section (1) and author of section (2), where the reception of Aristotle's school treatises is set out as a key feature in the transition from Post Hellenistic to Late Antique philosophy. Plotinus has a pivotal position in this process and the Neoplatonic incorporation of Aristotle's treatises would have not taken place without Plotinus' contribution
A Rediscovered Categories Commentary
No full textThis article is a preliminary edition — introduction, text, translation, commentary — of a previously unknown commentary on Aristotle’s Categories, recently discovered in the Archimedes Palimpsest. The two lemmas covered (both incompletely) in the fourteen surviving pages are 1a20-b15, concerning the distinction between ‘said of a subject’ and ‘in a subject’, and 1b16-24, where Aristotle maintains that different genera are divided by different differentiae. By extrapolating from this sample, the commentary can be inferred to have been considerably longer than the longest Categories commentary to survive intact, that of Simplicius. On this and other grounds, we argue that it is probably a fragment of Porphyry’s monumental lost commentary, the Ad Gedalium. A prominent feature of the new commentary is its extensive concentration on resolving puzzles raised against the Categories. Some of the material is completely absent from the remainder of the surviving Categories tradition. The earlier commentators and critics cited by name in it are Andronicus, Boethus, Nicostratus and Herminus
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
Field-Weakening Vector Controlled and DTC PMSM Drives, a Comparative Analysis
No full textThe present paper gives a comparative
analysis of field-weakening in vector controlled and
DTC permanent magnet synchronous motor drives. For
this purpose first the fundamentals of these drives are
discussed. The results of extensive simulations and a
comprehensive set of experiments are given. The
possibility of unstable operation in the high-speed
region using DTC has been shown. Important
differences between the compared drives have also
been emphasised, such as quickness of response, ripple
content and implementation aspects
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
