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

En algunas ocasiones éstas son tan minúsculas que han pasado totalmente inadvertidas, en otras son muy evidentes pero son soterradas ante la abrumadora cantidad de colecciones con las que cuentan o bien, ante la falta de personal frente la recurrencia de actividades emergentes que a éstos se les exige. Al comparar el estado de condición de un objeto con su historia particular registrada en un sin número de acervos documentales, encontramos que hay numerosos puntos de convergencia: relaciones directas entre lo asentado en los archivos institucionales y los deterioros, incidencias o restauraciones que evidencian. El entorno temporal se impregna en ellos, de la misma forma en que las letras son rociadas en los informes de los profesionales de los museos, a veces generando grandes cicatrices o faltantes, en ocasiones sólo perceptibles a nivel molecular.

Adicionalmente, se muestra un experimento museal fortuito que evidencía la validez de uno de los reclamos más asiduos en los museos: No tocar las piezas.Heritage objects sheltered at museum precincts of the entire world have to endure all kind of incidences, as a result of their daily inherent activities. Sometimes, these occurrences are so small that they go completely unnoticed; on other occasions they are very obvious, but they are soon forgotten, buried bythe overwhelming amount of collections which museums keep versus the lack of personnel and the recurrence of emerging activities which are required. When comparing the condition of an object with its particular history, recorded in a number of documentary collections, we find that there are numerous points of convergence; direct relations between what is settled in the institutional archives and the deterioration, incidences or restoration treatments that they evidence. The temporal environment marks them in the same manners as letters are poured into the reports of museum professionals, sometimes generating great scars or lacunae, often, only perceptible at molecular levels. Studying these incidents at this level of depth, allows to put forward new research models and, from that, to design new measures or products oriented to the conservation of the collections. The case study of a foundational sculpture of Mexican heritage tells us, tangentially and in detail, the history of how the National Museum was formed and developed. The technology we currently have allows us to examine past procedures and methodologies, which used to be innovative, but are now obsolete, which helps break down axioms of museums and academics. Additionally, a fortuitous museum experiment is shown to demonstrate the validity of one of the most frequent complaints in museums: Do not touch the objects

Dispelling 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
