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
Análisis preliminar del servicio del transporte público del corregimiento de Ancón Área revertida (2005 – 2007)
Get PDFThis study focused on seven of the most used bus line of the public transport in (Corregimiento) Ancon, which was administrated by the United States government until 1979. Under Panamanian administration, these areas have become an alternative for the development and expansion of Panama City, it has led to constant movements of persons from different social strata, who work, make use of the facilities or carry out procedures. Alongside the public transportation has undergone substantial change in service due to the large volume of users, expansion of roads, introduction of new routes between the existing logistics and the complete renovation of the equipment. The study was divided in two phases, for a better understanding of the problem. During the first phase, were implemented all the necessary activities to become familiar with the logistic of transportation service in order to get accurate data, which could help us to extract information and to identify variables which can be use for a complete analysis of the problem. In the second phase was making a representation of the user’s behavior through probabilistic model and specify the queue model associated to the system. This could give us bases to propose a solution. .El estudio se centró en siete de las rutas más utilizadas del Corregimiento de Ancón, que estuvo la administración del gobierno de los Estados Unidos hasta el año 1979. Bajo administración panameña, estas áreas se convirtieron en una alternativa para el desarrollo y extensión de la ciudad de Panamá, lo que ha ocasionado constantes movilizaciones de personas, de distintos estratos sociales, que laboran, hacen uso de las instalaciones o realizan tramitaciones, produciendo toda una faena trasladarse hacia dentro y fuera de los distintos puntos. Paralelamente el transporte colectivo ha sufrido cambios considerables en el servicio debido al gran volumen de usuarios, la ampliación de vías, la introducción de nuevas rutas entre las existentes con la misma logística y sin renovación completa de los equipos. El estudio se dividió en dos fases, para una mejor comprensión del problema. En la primera fase se ejecutó toda la actividad necesaria para familiarizarse con la logística del servicio del transporte y obtener datos precisos de esto. Un aspecto importante fue encontrar la representación del comportamiento de los usuarios y el servicio a los mismos, por medio de funciones de distribuciones de probabilidad, así como especificar el modelo de cola asociado al sistema, cuyos componentes puedan arrojar resultados significativos para la solución
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
