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
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
Il dibattito sul rapporto tra filosofia platonica e totalitarismo negli anni ’30 e ’40 del XX secolo: breve bibliografia ragionata
No full textDispelling 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
Chiedilo al bibliotecario. Analisi di un servizio di reference digitale e della sua realizzazione da parte del Sistema bibliotecario di ateneo dell'Universita' di Pisa
No full textQuesto lavoro sviluppa un’analisi relativa a un servizio specifico del cosiddetto reference service digitale, vale a dire la tipologia denominata Chiedilo al bibliotecario. Più precisamente, il tema è esemplificato e approfondito attraverso la descrizione della sua realizzazione da parte del Sistema bibliotecario di ateneo dell’Università di Pisa. In particolare, nella prima parte, si fornisce una definizione di tale servizio, contestualizzandolo nell’ambito più ampio della storia del reference service bibliotecario e, più precisamente, in quella del reference digitale. Si analizzano quindi nello specifico le sue caratteristiche fondamentali, prendendo in esame le principali esperienze estere e italiane, con una particolare attenzione all’ambito accademico. Nella seconda parte, si approfondisce invece un’esperienza concreta, relativa cioè all’attivazione di tale servizio presso il Sistema bibliotecario di ateneo dell’Università di Pisa. Più specificamente, se ne illustrano la storia, le caratteristiche fondamentali, nonché le più recenti evoluzioni relative soprattutto alla visibilità del servizio attraverso il social network Facebook. L’analisi è anche arricchita da dati statistici. Infine, nelle conclusioni, alla luce di questo studio e dell’esperienza concreta presa in considerazione, si mettono in evidenza le potenzialità e prospettive future di tale servizio, principalmente in ambito accademico.
This work analyses a specific service of the so-called digital reference service, that is to say ask a librarian. The subject is illustrated by the description of its realization by the Librarian System of the University of Pisa. In the first part, we provide a definition, placing this service in the reference service’s general history and in particular in the digital reference service’s history. Then we study its fundamental characteristics, looking at the main foreign and Italian practices, paying a particular attention to the academic sphere. In the second part, we deepen a concrete experience, that is to say this service’s realization by the Librarian System of the University of Pisa. In particular, we examine this service’s history, its characteristics and development concerning its visibility on the social network Facebook. The work is also enriched by statistical data. In the end, in the light of this research, we focalize on this service’s future potentialities and chances, mainly in the academic sphere
Platone ed il totalitarismo negli anni '30 e '40 del XX secolo
No full textL'oggetto di questo lavoro è il dibattito riguardante il rapporto tra filosofia platonica e totalitarismo, come emerge dagli scritti di alcuni autori degli anni '30 e '40 del XX secolo, prima che K.R.Popper, nel 1945, desse alle stampe la sua opera, The Open Society and its Enemies. Infatti, a partire da quegli anni si sviluppa un'accesa discussione riguardante il pensiero di Platone, soprattutto in merito alle sue conseguenze politiche. In precedenza, l'atteggiamento degli studiosi nei confronti di questo filosofo era stato favorevole, variando in intensità da una semplice simpatia ad una vera e propria idolatria. Da quel momento, invece, diversi autori iniziano a scagliarsi contro il suo pensiero, che viene accusato, sotto vari punti di vista, di fornire le basi teoriche per la giustificazione di quei regimi totalitari che si erano affermati o che si stavano affermando nel medesimo periodo. Tali scritti culminano con la pubblicazione dell'opera di K.R.Popper, The Open Society and its Enemies, che in seguito influenzerà l'interpretazione del pensiero platonico, soprattutto nell'epoca della guerra fredda. Non mancano, tuttavia, accanto a queste posizioni accusatorie, anche autori che sostengono la tesi opposta e tentano di dimostrare che quello in atto è in realtà il travisamento di un autore, che viene strumentalizzato ed usato arbitrariamente all'interno delle dispute moderne e che invece dovrebbe essere ricollocato nella prospettiva storico-culturale della sua epoca.
L'intento di questo scritto è in primo luogo mettere in evidenza la grande diversità interpretativa di cui è stata fatta oggetto la filosofia platonica in quegli anni: per alcuni Platone è un filosofo antesignano delle ideologie totalitarie moderne, per altri è possibile invece rintracciare nella sua opera elementi anticipatori del moderno Stato liberale e di diritto. In secondo luogo e soprattutto in riferimento a questo secondo parere, preme qui rivalorizzare posizioni che sono passate in secondo piano e che invece possono avere il pregio di insinuare un ragionevole dubbio rispetto ad interpretazioni nette come quella di Popper che lo considera un filosofo precursore del totalitarismo.

The subject of this work is the debate on the relation between Plato’s philosophy and totalitarianism, as it emerges from the writings of some authors in the Thirties and in the Forties of the twentieth century, before K.R.Popper’s work, The Open Society and its Enemies, was published in 1945. Since then, the debate on Plato’s thought and mainly on its political implications has been heated. Previously, the scholars’ attitude towards this thinker was favourable, ranging from simple approbation to true idolatry. On the contrary, from the publication of Popper’s work onwards, several authors start criticising his thought. They variously accuse Plato of providing the theoretical bases for justifying the established or establishing totalitarian regimes of that time. As previously mentioned, such works culminate in the publication of K.R.Popper’s writing, The Open Society and its Enemies, which will greatly influence the interpretation of the Platonic thought afterwards, mainly during the Cold War. Besides these accusatory points of view, there are authors who support the opposite thesis and who try to demonstrate that there was a misinterpretation of Plato. According to them, Plato has been exploited and arbitrarily used in modern debates instead of perceiving him in the right historical and cultural background of his epoch.
Firstly, the purpose of this work is to show the wide variety of interpretations of the Platonic philosophy in those years. Some thinkers consider Plato as a forerunner of modern totalitarian ideologies; others think he is the precursor of the modern and liberal State and of the Rule of Law. Secondly, and mainly with reference to the latter opinion, it is fundamental to reconsider some points of view which have been underestimated. Indeed, these neglected perspectives may cast a different light on the matter, especially in comparison to Popper’s rigid interpretation and to similar ones, which consider Plato a forerunner of totalitarianism.</p
