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
Dispelling the Myths Behind First-author Citation Counts
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
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
DAMyRE : diseños analógicos melódicos y reformulaciones educativas
No full textResumen: Los Diseños Melódicos son temáticas escasas en el campo educativo si bien muchos teóricos (Wuytack 1971, Adams 1976, Dowling1984, Fernández Calvo 2007), han planteado diferentes ideas y corrientes conceptuales, como el trazado de movimientos de alturas en un espacio, perfiles melódicos y representaciones visuales comprensibles (Furnó 1996 y Malbrán 2004), poco después en el área de la educación musical postularon premisas fundamentales de diseños básicos topográficos para iniciar un desarrollo pedagógico/didáctico que circunscribe un constructo a constituir en este compendio. Se conformaron 16 DAM (Diseños Analógicos Melódicos) audios/visuales con música real en diferentes géneros musicales permitiendo centrar bases de construcción para el campo educativo y llevarlos a cabo en la acción áulica mediante la audición activa de la Estructura Formal. Se testearon 4 escuelas públicas; una de nivel Primario y tres de nivel Secundario de diferentes contextos sociales, arrojando datos empíricos de cómo elaborar el contenido DAM, cuáles son los recursos didácticos para poner en marcha, la intervención pedagógica conceptualizada de la Mnemotecnia melódica y la génesis de los diseños para realizar la invención y el desarrollo de un material didáctico autentico, renovado, que proponga distintas competencias musicales para la educación musical contemporánea.Abstract: The melodic designs are scarce themes in the educational field, although many theorists (Wuytack 1971, Adams 1976, Dowling1984, Fernández Calvo 2007) have raised different ideas and conceptual currents, such as the tracing of heights in a space, melodic profiles and (Furnó 1996 and Malbrán 2004), shortly afterwards in the area of music education postulated fundamental premises of basic topographic designs to initiate a pedagogical / didactic development that circumscribes a construct to be constituted in this compendium. 16 audio / visual DAMs were formed with real music in different musical genres, allowing to center construction bases for the educational field and to carry them out in the acoustic action through the active hearing of the Formal Structure. Four public schools were tested; One of Primary level and three of secondary level of different social contexts, providing empirical data on how to elaborate the DAM content, what are the didactic resources to put in place, the pedagogical intervention conceptualized of the melodic Mnemotecnia and the genesis of the designs to realize The invention and the development of authentic, renovated didactic material that proposes different musical competitions for contemporary musical education.Fil: Merlo, Daniel Andrés.
