Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
16 Cards to Get Into Computer Organization
This paper presents a novel educative activity for teaching computer architecture fundamentals. This activity is actually a game that uses 16 cards and involves about twenty active participant students. Executing this activity in the fi rst class of the course allows the studentin only 45 minutes to acquire the fundamental concepts of computer organization. The results of the surveys that evaluate the proposed activity
together with the grades obtained by the students at the end of course corroborate the importance of the proposed game in the assimilation of more complex concepts in computer architecture.Universidad de Granada: Departamento de Arquitectura y Tecnología de Computadores; Vicerrectorado para la Garantía de la Calidad
Variations on the Author
“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
We 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
We 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
We 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
Algoritmos multicore para el cálculo de parámetros de visibilidad en sistemas de información geográfica
Fecha de lectura de Tesis: 16 de octubre 2018.La mayoría de los algoritmos de visibilidad en Sistemas de Información Geográfica (SIG) se basan en el cálculo y análisis de las Cuencas Visuales desde un punto o a lo sumo desde un conjunto limitado de puntos.
El cálculo del conjunto de Cuencas Visuales para todos los posibles observadores situados en el territorio proporcionaría una información mucho más valiosa, ya que permitiría determinar fácilmente la visibilidad de un observador que se desplaza. La complejidad del cálculo por el volumen de operaciones hace casi imposible la computación de las Cuencas Visuales sobre muchos puntos. Por otro lado, dicha información sería más valiosa aún si los datos calculados tuvieran un carácter tridimensional (Volumen Visible) que realzaran la calidad de la Cuenca Visual. Además, las Cuencas Visuales pueden ayudar a posicionar un conjunto de observadores para cubran la mayor o toda la superficie de un terreno. Hecho de vital importancia en muchas áreas (vigilancia contra incendios, vigilancia en zonas bélicas, posicionamiento de torres de telefonía,...)
El objetivo de esta tesis consiste en el desarrollo de soluciones eficientes a problemas realistas de visibilidad. En concreto, nuestro objetivo principal ha sido el desarrollo de algoritmos precisos y escalables para el cálculo de los parámetros de visibilidad en MDE de mediana y gran escala usando las arquitecturas de computadores actuales. Dentro de los parámetros de visibilidad nos hemos centrado en el cálculo de 1)Cuencas Visuales, 2)Visibilidad Volumétrica.
Una vez calculados estos parámetros, nuestro propósito es utilizarlos para la resolución de problemas reales como, el cálculo del mínimo número de observadores que cubran el mayor área de un territorio. Las claves de los algoritmos propuestos son; 1) una estructura de datos adecuada, 2) alta reutilización de datos en la computación y lo más importante, 3) alta escalabilidad en los sistemas de computación de alto rendimiento
