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
Análisis notacional en jugadores de tenis de élite en función de las variables contextuales
Get PDFThe aim of the present study was to identify the main performance differences among the top 3 male tennis players: Federer, Djokovic and Nadal. To do so, the players’ game statistics were gathered from the open access web domain. Firstly, the results from the Binomial Logistic regression allowed identifying the key contextual variables that affect the players’ performance. Then, performance profiles were done according to these variables that highly affected the players’ performance (game contexts). Secondly, the main results showed that each player has different performance profile than the other players. In addition, the contextual variables of court surface, round or quality of opposition were identified as those that best differentiated the players’ performances. This type of notational analysis is very useful for coaches and players due to the fact that allow controlling the game dynamics and training plans in top level tennis.El objetivo de la presente investigación ha sido analizar las principales diferencias entre los tres jugadores más destacados en el circuito ATP: Federer, Djokovic y Nadal. Se recogieron estadísticas de juego de estos jugadores a través de las páginas oficiales de los torneos de Roland Garros y Wimbledon. Un análisis de regresión logística binaria permitió identificar variables que influenciaban en su rendimiento, procediendo a elaborar perfiles de cada uno de los jugadores y ajustándolos a cada contexto específico de juego. Los resultados encontrados muestran que cada uno de estos jugadores tenía perfiles de juego diferentes y que había variables contextuales como la superficie sobre la que se juega, la ronda que se disputa o la calidad del oponente, que influían en su rendimiento. Este tipo de análisis es muy útil para entrenadores y jugadores ya que permiten controlar dinámicas del juego así como la planificación de entrenamientos en el tenis de alto nivel
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
