Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
La concezione della dimensione corporea e della sua genesi nella filosofia di Plotino
No full textIl lavoro, articolato in tre capitoli, analizza la concezione della dimensione corporea e la questione della sua genesi nella filosofia di Plotino (P.). Nel cap. 1 si ricostruisce il dibattito critico sull'origine della materia prima e si argomenta in favore della tesi di O'Brien (la materia è generata dall'anima). Nel cap. 2 si mettono in luce le proprietà che caratterizzano il corpo fisico in quanto tale: questo viene descritto da P. sia come estensione tridimensionale dotata di resistenza, sia come livello del reale contraddistinto dalla parcellizzazione (μερισμός). Nel cap. 3 si esamina la genesi di tali proprietà: per quanto riguarda l'estensione spaziale, P. ritiene che la materia sia inestesa e fa derivare la grandezza (così come la resistenza) dalle forme; se queste si manifestano nel sensibile sotto forma di estensione è però a causa della loro ricezione da parte della materia. Si ricostruiscono i presupposti teorici di tale concezione e il suo rapporto con la tradizione precedente e contemporanea a P. La parcellizzazione ha invece origine soltanto materiale; si esaminano il suo ambiguo rapporto con il luogo e con l'estensione e i problemi che esso pone: la parcellizzazione viene talvolta trattata da P. come se coincidesse con l'estensione, ma, avendo origine e natura differenti, non può che esserne distinta. Seguono due appendici, sul significato del sostantivo ὄγκος e sul rapporto tra la concezione plotiniana della materia e la settima ipotesi del Parmenide
On Matter and the Physical Realm: The Neoplatonic Interpretations of Hypotheses 4-9 of Plato's "Parmenides"
No full textQuesta tesi esamina le interpretazioni neoplatoniche delle “ipotesi” 4-9 del Parmenide di Platone, che i neoplatonici generalmente associavano alla materia e al mondo fisico, e le loro concezioni di queste entità. La tesi consiste di quattro parti più un’appendice. La prima parte ha carattere introduttivo. La seconda parte si sofferma su Plotino e i suoi allievi Amelio e Porfirio. In primo luogo, si argomenta che Plotino concepiva l’ottava ipotesi come una descrizione della materia prima considerata nella sua relazione con le forme immateriate. Successivamente, si chiarisce il significato delle identificazioni dei soggetti delle ipotesi sostenute da Amelio e Porfirio: entrambi i commentatori “importano” la distinzione tra vari sostrati materiali dalla loro esegesi del Timeo in quella del Parmenide. Inoltre, si mettono in luce due principi ermeneutici che stanno alla base delle loro interpretazioni delle ipotesi, la cui individuazione consente di spiegare molte delle apparenti stranezze di tali interpretazioni.
La terza parte esamina lo sviluppo dell’esegesi del Parmenide da Giamblico a Damascio (compreso).
La quarta parte si sofferma su Damascio. Dopo un’analisi di alcuni passi significativi del suo commento alle ipotesi 4-6 e 8, si discutono due teorie di importanza centrale per la sua concezione del mondo materiale: la sua dottrina della materia prima come prodotto del principio ineffabile (invece che dell’uno, come Damascio dava per scontato nel De Principiis), e la sua analisi della relazione tra materia e forma nel composto sensibile – un ambito in cui Damascio, sulla scia di Proclo, tenta di conciliare la dottrina attribuita a Platone con quella aristotelica. Nel corso dell’analisi, si investigano anche il rapporto tra Damascio e Proclo e il rapporto tra dialettica ed esegesi nel commento di Damascio alle ipotesi 4-9.
L’appendice contiene degli addenda et corrigenda all’edizione Budé del commento di Damascio al Parmenide.
This thesis explores the Neoplatonic interpretations of “hypotheses” 4-9 of Plato’s Parmenides, which the Neoplatonists generally associated with matter and the physical realm, as well as their conceptions of these entities. The thesis consists of four parts and an appendix. The first part is an introduction. The second part focuses on Plotinus and his pupils, Amelius and Porphyry. First, I show that Plotinus took the eighth hypothesis to be a description of prime matter considered in relation to enmattered forms. I then elucidate the meaning of Amelius’ and Porphyry’s identifications of the subject-matters of the hypotheses: both commentators “imported” the distinction between various material layers from their interpretation of the Timaeus into that of the Parmenides. Furthermore, I spell out two competing hermeneutic principles that govern Amelius’ and Porphyry’s interpretations of hypotheses 4-9 and explain many of their apparent oddities.
Part 3 surveys the evolution of the Parmenides exegesis from Iamblichus up to, and including, Damascius.
Part 4 focuses on Damascius. After analysing some central passages of his commentary on hypotheses 4-6 and 8, I discuss and assess two fundamental theories that form the basis of his conception of the material realm: namely, his theory of prime matter as an offspring of the ineffable principle (rather than of the one, as he had assumed in the De principiis), and his description of the matter-form relation in the sensible composite – a domain in which Damascius, following Proclus, tries to reconcile the (supposedly) Platonic and the Aristotelian account. In doing so, I also shed light on the relation between Damascius and Proclus and on the relation between dialectics and exegesis in Damascius’ commentary on hypotheses 4-9.
The appendix contains some additions and corrections to the Budé edition of Damascius’ commentary on the Parmenides
Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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
