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
Earth rotation via doppler shifts?
No full textStedman cites many successfully experiments regarding the measurement of the Earth’s rotation via the Sagnac effect. He addresses the important fact that Sagnac measurements can be interpreted as a Doppler effect. In a rotating interferometer all optical components are moving, and therefore each one produces a Doppler shift. Accounting for the total contribution of all the mirrors, the standard Sagnac formula is recovered. We want to clarify the fact that we referred to the value of the Earth’s rotational rate as an example of what we call low rotational speed rather than a proposal to measure the Earth’s rotation by means of our apparatus. As suggested by a reviewer, one could mount the mirror on a motorized rotation stage and move it very slowly. Our apparatus may be used to show students how to detect very low rotational speeds.Fil: Bernal, Luis. Universidad Nacional de Mar del Plata. Facultad de Ciencias Exactas y Naturales.

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

Get PDFLa empresa familiar es una fuente económica del seno familiar, nutre y retroalimenta aspectos importantes como el negocio, el patrimonio y la relación entre los miembros de la familia. El impacto social que implica la solución de conflictos en empresas familiares radica en que, de acuerdo a las cifras del Instituto Mexicano de Contadores Públicos, el 50% y el 80% de las empresas del mundo son familiares, generando aproximadamente el 50% del producto interno bruto (PIB) a nivel mundial y se estima que el 90% de las empresas mexicanas establecidas están bajo el control y propiedad de una familia. Ello revela la trascendental contribución de las empresas familiares al desarrollo económico, social y cultural en el contexto mexicano y mundial. En el presente trabajo se utiliza una metodología de revisión bibliográfica sistemática la cual permite estudiar de forma prospectiva los conflictos entre socios de empresas familiares a través de los modelos de mediación, con el objetivo de analizar la viabilidad de implementación de dichos modelos en la solución de conflictos en empresas familiares, sin importar su conformación ni tamaño, sino más bien, la evolución y crecimiento económico y generacional de la corporación
