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
Niveles de representación e interpretación semántica: breve historia y estudio de caso
No full textThe nature of the relationship between sentence form and meaning has been an important concern in generative grammar from the inception of the program. Chomsky (1955) raised the question of whether transformations preserve meaning. The suggested answer was negative at that time, and the locus of interpretation was the T-marker, the entire derivational history. In the standard theory of Chomsky (1965), it was proposed, based on work of Katz, Fodor, and Postal, that Deep Structure, a level newly proposed in that work, is the locus of semantic interpretation, though it was acknowledged that quantifiers raise certain difficulties. Those difficulties, along with similar ones involving anaphoric relations, led to the Extended Standard Theory, where Deep and Surface Structure jointly input interpretation, and soon, with the advent of traces, Surface Structure alone. In subsequent models within the GB framework, the derived syntactic level of LF becomes the sole locus of interpretation. Finally, in more recent Minimalist Chomskyan work, there is argued to be no one level of LF; rather, semantic interpretation is interspersed among cyclic steps of the syntactic derivation, reminiscent of the LSLT proposal, though more restricted, and very similar to proposals of Jackendoff and Lasnik in the 1970\u27s. I will try to sort through the motivations for these changes, focusing especially on the problem of quantifier interpretation.La naturaleza de la relación entre la forma y el significado de una oración ha sido una preocupación importante en la gramática generativa desde sus inicios. Chomsky (1955) se preguntó si las transformaciones preservan el significado. La respuesta sugerida en esa época era que no, y donde se situaba la interpretación era el marcador-T (T-marker), la historia derivacional en su totalidad. En la teoría estándar de Chomsky (1965) se propuso, basado en trabajos de Katz, Fodor, y Postal, que la Estructura Profunda, un nuevo nivel propuesto en este trabajo, es donde se sitúa la interpretación semántica, aunque se reconoció que los cuantificadores presentan ciertas dificultades. Estas dificultades, en conjunto con otras similares que involucran relaciones anafóricas, llevaron a la Teoría Estándar Extendida, donde las Estructuras Profundas y Superficiales asignan interpretación en conjunto, y poco tiempo después, con la llegada de las huellas, la Estructura Superficial por sí sola lo hace. En modelos siguientes dentro del marco teórico de Rección y Ligamiento, el nivel sintáctico derivado de FL se convierte en el único lugar donde se sitúa la interpretación. Finalmente, en trabajo más reciente Minimalista Chomskyano, se argumenta que no existe un único nivel de FL; al contrario, la interpretación semántica se entremezcla en los pasos cíclicos de la derivación sintáctica, en una forma que hace recordar la propuesta de LSLT, aunque siendo más restringida, y muy similar a las propuestas de Jackendoff y Lasnik de la década de 1970. Intentaré explicar las motivaciones que llevaron a estos cambios, enfocándome en particular en el problema de la interpretación de cuantificadores
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
