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
Gli spazi infiniti e la storia: su alcune metamorfosi del topos stellare
No full textIl saggio esamina come un topos apparentemente meta-storico (lo squarcio celeste e stellare) sia sempre rimotivato sul piano storico. Confrontarsi con le stelle lontane è dunque sempre un modo per fare i conti con la propria contemporaneita

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
Towards Lessness: Sulle forme brevi di Samuel Beckett
No full textSamuel Beckett's obstinate attempt at contracting literary forms characterizes his whole literary trajectory and makes of him one of the undisputed masters of the short form. This may be surprising, considering that among the most significant influences in his early career there were Marcel Proust – an arch-enemy of the short form if ever there was one – and the equally long-winded James Joyce. In spite of such progenitors, Beckett's artistic research seems to have been inspired by a desire for conciseness and compactness that brought him to kill his fathers early in his career and move as far as possible from them. Starting from his early works Beckett consecrated his career to a systematic, almost obsessive, exercise in “subtracting, taking away”: an exploration of concentrated forms and shrinking proportions that produced texts whose dimensions are inversely proportional to their density.
Analyzing some of the most significant texts, I discuss the intrinsic reasons of these formal experiments in the light of Beckett's whole artistic trajectory. First I highlight how Beckett's short forms are not to be considered as something given, but as the result of a process. Then, I propose a typology of techniques characterizing the two opposite but complementary aspects of such process: abstraction on the one hand – produced by means of symmetry and excavation – and complication on the other – produced by means of fragmentation and condensation. Geometrical simplification and condensed complication, the external compression of form and the internal contraction of matter: Samuel Beckett finds a balance between these two complementary aspects, creating works that are at the same time miniaturized and distilled, cameos and fragments
