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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Los recursos gráficos en el manuscrito de cantería atribuido a Pedro de Albiz (BNE Ms 12686)
Get PDF[SPA] En la Biblioteca Nacional de Madrid se conservan varios manuscritos de cantería. Uno de ellos, el número 12686, anónimo, sin título y de fecha indeterminada, incluye diversas trazas en proyección ortográfica doble o múltiple, empleando diferentes recursos gráficos para hallar las plantillas de las caras de las dovelas, los ángulos entre sus aristas o sus sólidos capaces, con objeto de controlar la labra de las piezas. Otros dibujos representan en planta bóvedas de crucería con terceletes y combados. Se completa con dos dibujos del orden toscano tomados de la Regola delli cinque ordini d'Architettura de Vignola y el alzado del fuste de una columna salomónica. El texto se ha vinculado sucesivamente a Alonso de Vandelvira (Barbé 1977), Pedro de Alviz (Gómez Martínez 1998, p. 31-32) y Felipe Lázaro de Goiti (Suárez Quevedo 2002). Por el contrario, apenas se han estudiado los problemas que plantea la obra desde el punto de vista geométrico y constructivo. Nos proponemos en este trabajo abordar un primer cercamiento al manuscrito basándonos en un análisis de las técnicas gráficas y métodos de construcción empleadas en los dibujos, estudiando en particular los modos de proyección y recursos gráficos como desarrollos y triangulaciones. Este enfoque puede proporcionar datos útiles para comprender tanto el manuscrito en sí como sus conexiones con otros textos de cantería ibérica, como los de Hernán Ruiz el Joven (c. 1550), Alonso de Vandelvira (c. 1580), Ginés Martínez de Aranda (c. 1600), Juan de Portor y Castro (1708), y el llamado de Juan de Aguirre (c. 1600), confirmando o rebatiendo al mismo tiempo las atribuciones realizadas hasta el momento.[ENG] The Biblioteca Nacional de España in Madrid holds a fair number of stonecutting manuscripts. One of them, MS 12686, including 31 sheets in parchment binding, and bearing no author mention, title or date, has not been studied from a geometrical point of view. In this paper, we present a preliminary study of the manuscript, analysing the graphical techniques and construction methods used in the drawings, dealing in particular with projection types and graphical resources such as developments and triangulations. Such research approach furnishes valuable data about the connections of the manuscript with other important stonecutting texts in the Iberian area, such as the ones by Hernán Hernán Ruiz el Joven (c. 1550), Alonso de Vandelvira (c. 1580), Ginés Martínez de Aranda (c. 1600) and Juan de Portor y Castro (1708), supporting the attribution posited by Gómez Martínez (1998) to Pedro de Alviz, a stonemason active around 1540 in the Cuenca area
