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
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
Programa de habilidades sociales para mejorar el desempeño docente en la I.E. N° 10675 de Achiramayo, Ninabamba, Santa Cruz, 2014
Teniendo en cuenta la problemática del bajo nivel de desempeño en los docentes
se hace necesario la aplicación de un programa orientado al desarrollo de
habilidades sociales básicas; por lo que la investigación queda descrita de la
siguiente manera: programa de habilidades sociales para mejorar el desempeño
docente en la LE. N° 10675 de Achiramayo, Ninabamba, Santa Cruz, 2014,
dicha problemática se refirió en función de la carencia de habilidades sociales
básicas de los docentes, siendo ésta la variable independiente del estudio, que
fue abordada mediante la variable dependiente.
Por tanto el objetivo general de la investigación fue comprobar la eficacia del
programa, siendo necesario para ellos cumplir con los objetivos específicos que
se lograron al identificar el nivel de desarrollo del desempeño docente mediante
el pre test, aplicar la propuesta con los docentes del grupo experimental y
posteriormente identificar la variación en el nivel de dicho desempeño a través de
un post test. Dichos objetivos permitieron dar respuesta al problema planteado y
enunciado de la siguiente manera ¿Qué efectos produce la aplicación de un
programa de las habilidades sociales en el desempeño docente en la LE. N°
10675 de Achiramayo, Ninabamba, Santa Cruz, 2014.
Frente al problema formulado, se asumió como hipótesis general que la aplicación
de un programa de habilidades sociales, mejora significativamente el desempeño
docente en la LE. N° 10675 de Achiramayo, Ninabamba, Santa Cruz, 2014. La
población participante fue de 9 docentes, la muestra elegida fue a través del
muestreo aleatorio simple
Al finalizar la propuesta del programa se logró obtener un promedio de 60,33
puntos que lo ubica en la categoría bueno del nivel de desempeño docente,
corroborado por un 33,3% y un 55,6% que se ubicaron en la categoría regular y
bueno respectivamente del nivel de desempeño docente. Estos resultados
confirman la eficiencia y eficacia de la propuesta, tal como lo muestra la diferencia
significativa de promedios en 11,77 Puntos, logrando con ello aceptar la hipótesis
planteada y rechazar la hipótesis nul
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
