Perceiving and categorizing atonal music: the role of redundancy and performance
In order to verify if the performer interpretation has a role on the perceived segmentation of atonal music, we performed three experiments according to the ecological approach developed by Irène Deliège (1990). We hypothesize that musical structure affects grouping more than performance and, moreover, that the main mechanism involved in the representation of musical structure is related to the detection of similarity and difference between phrases, that is, of their redundancy. For each experiment 30 subjects were invited to attentively listen to two different performances of an atonal piece, to understand its plan and to mark off the sections of the work pressing a computer key. The order of presentation of the two performances was balanced. In a first experiment we used two versions of Berio’s Sequenza VI performed respectively by Desjardins (1998) and Knox (2006). These variants are different in duration (12.13min. vs 13.14min.) and show differences in dynamics aspects (i.e.: velocity, intensity), accents distribution and gaps duration. The aim of this work was to isolate and analyze the role of variations in dynamic components, accents distribution, duration and the instrumentalists’ point of view in the representation of the musical surface, as perceived by the listeners. In the second experiment we focused on the role of performances duration by using two versions of Berio’s Sequenza III, recorded by the same singer, that differ exactly in duration. In order to better investigate the performers interpretation of the score, in the third experiment we asked to two musicians to record a performance of Berio’s Sequenza VIII by means of a score in which we had previously erased the dynamic instructions provided by the composer. Moreover, none of the two instrumentalists knew the Berio’s composition before our request. Then we used the obtained tracks as stimuli in the same paradigm of previous experiments. The results show a good number of coinciding segmentations in the two versions either for the first, the second and the last experiment, confirming our hypothesis and suggesting a main role of the texture in perceiving and representing the plan of the pieces. The results of the three experiments are discussed in relation to the role of same/different detectio

Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
