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
Music and Emotion. Review of "Music and Emotion", monographic issue of the journal «Music Analysis», edited by Michael Spitzer, n. 29/1-2-3 (2010)
No full textThe last fifteen years have seen the development of a lively interest, on an international scale, in the topic of emotion in music, documented by numerous noteworthy publications: the two volumes edited by Juslin and Sloboda [2001; 2010], the monographic issues of the journal «Musicae Scientiae» published in 2001 and 2011, and many other texts published in various parts of the world. The topic is not without repercussions also for those involved in musical analysis; and it is no mere chance that the English journal «Music Analysis» chose to dedicate the volume we are now reviewing to the subject. The contributions contained in the volume derive from an international meeting held in Durham in September 2009 and offer a fairly lively cross-section of a wide series of questions. Our only regret is that with the exception of three nordic names (Juslin, Lindström and Eerola, whose place is now solidly established in English language publications) all the authors come from the now almost self-referential context of British or American research. But of course this is nothing new
Musica ed emozioni
No full textThe Special Issue on Music and Emotion published by «Music Analysis» in 2010 has been a stimulating reading for members of the Scientific Board of the «Rivista di Analisi e Teoria Musicale», who invited the authors of the present article to write a review. The wealth of ideas, approaches and methodological perspectives proposed in this volume, however, is such that it became soon evident that it would be better to give this review the shape of an essay which summarizes and discusses in a critical perspective the content of the volume; but at the same time it also provides a more general discussion of the concept of emotion in music, highlighting some important theoretical and terminological issues.
The essay is divided into five parts: after a brief description of the contents of Music and Emotion, the second part presents a survey of the different meanings of the concept of emotion within the volume, while the third provides an overview of the possible facets of the concept of emotion as applied to music. In the fourth part Luca Marconi examines the relationship between musical analysis and the study of emotions, stressing the need for an approach open to the integration of different methodological perspectives. The last part, written by Mario Baroni, discusses the concept of emotion “perceived within the musical text” in the listening of European classical music, and emphasizes how this kind of music can induce a complex emotional experience which is very different from the so-called “basic emotions” of daily life, which are the main object of study of the psychology of music.
La lettura del volume monografico Music and Emotion pubblicato dalla rivista «Music Analysis» nel 2010 è risultata particolarmente stimolante per alcuni membri del comitato scientifico della «Rivista di Analisi e Teoria Musicale», che hanno invitato i tre autori dell’articolo a preparare una recensione. La ricchezza di idee, approcci e prospettive metodologiche proposte in questo volume ha tuttavia indotto i tre autori a scrivere un vero e proprio saggio: in cui si rende conto dei contenuti del volume recensito, e li si discute in prospettiva critica; ma in cui si propone anche una riflessione sulle possibili declinazioni del concetto di emozione in musica, e una discussione più approfondita di alcuni importanti nodi teorici e terminologici.
Il saggio si articola in cinque parti: dopo una sintetica descrizione dei contenuti di Music and Emotion, la seconda parte propone una ricognizione dei diversi significati che il concetto di emozione viene ad assumere all’interno dei vari contributi, mentre la terza ricostruisce una panoramica delle possibili sfaccettature dell’idea di emozione applicata alla musica. Nella quarta parte Luca Marconi prende in esame le relazioni fra l’analisi musicale e lo studio delle emozioni, sottolineando la necessità di un approccio aperto all’integrazione di varie prospettive metodologiche. L’ultima parte, di Mario Baroni, discute il concetto di emozione “percepita all’interno del testo musicale” applicandolo all’ascolto della musica di tradizione classica europea: un genere di musica che sollecita un’esperienza emozionale complessa e ben diversa dalle cosiddette “emozioni di base” della vita quotidiana, che costituiscono invece il principale oggetto di studio della psicologia della musica

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
