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
Sottosopra: Indagine su processi di sovversione
Full text link[Italiano]: L’idea di sovversione è un principio di movimento, segnato dall’etimo: volgere dal basso verso l’alto, ovvero cambiare di posto, invertire la rotta. Il rovesciamento dell’ordine precostituito attraversa ciclicamente la storia, manifestandosi in tutti gli ambiti della vita umana attraverso un atto rivoluzionario contingente che innesca a sua volta ulteriori processi di rigenerazione. Obiettivo di questo volume è, pertanto, quello di riconoscere e ricostruire il dialogo tra i segmenti che compongono le sovversioni della nostra storia socio-culturale, identificandone i contorni in una modalità dell’agire che fonda e sabota se stessa nello stesso momento in cui insorge.
Il discorso critico interdisciplinare qui condotto si sviluppa seguendo la tripartizione proposta da Thomas Ernst nei suoi numerosi studi riguardanti il concetto di sovversione nella cornice artistico-letteraria del Novecento, giovando della sua collaborazione che è confluita nel contributo con cui si apre il volume, intitolato Subversion Studies. The Political – The Media – The Public. Tale tripartizione è stata adottata e riletta dalle curatrici alla luce dei contributi proposti dagli autori, al fine di investigare ambiti differenti in cui il sovversivo manifesta la propria natura. In tal senso è stato posto l’accento prima sul politico, ovvero sulle condizioni di negoziazione tra un soggetto e il mondo esterno, successivamente sui media, nell’accezione di supporti dall’utilizzo potenzialmente rivoluzionario e, infine, sul pubblico, vale a dire sul dialogo tra l’eredità culturale e i suoi interpreti, colti nell’atto di riscrivere e tradire l’autorità della tradizione.
Il presente volume è dunque frutto di un’indagine collettiva e trova la propria collocazione all’interno dei Subversion Studies, branca del sapere di recente sviluppo. Alla base della sua composizione vi è uno sguardo duplice che tiene insieme presente e passato e che ricerca, anzitutto, la dimensione processuale insita in ogni espressione di rinnovamento
./[English]: According to its etymology, the concept of subversion traces a precise movement: the turning upside-down, that is, switching, reversing course. The overthrow of established paradigms periodically leaves its mark upon history, taking the form of a revolutionary act that, in turn, triggers further regenerations processes. In this framework, the subversive condition reveals its elusive nature, since it disappears in the moment of its fulfilment, hiding itself behind the curtains of every historical event.
Based on these considerations, this volume aims to outline subversion as a dynamic process of our socio-cultural history, whose different forms are shaped by the dialogue between opposing subjects. In doing so, this book positions itself firmly within the new-born field of Subversion Studies, offering an interdisciplinary double gaze, that, similarly to the same concept of subversion, holds together past and present.
The volume is divided into three sections: The Political – The Media – The Public, tripartition borrowed from the research carried out by Thomas Ernst - a leading exponent of Subversion Studies – whose article opens this volume. By applying this subdivision, we intend to draw attention to three different areas in which the Subversive manifests its own nature: firstly, the political negotiation between subjects and the outside world; secondly, media and their revolutionary use; and, finally, the cultural heritage and its interpreters, caught in the act of rewriting and subverting tradition

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
