Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
Work Engagement : A meta-Analysis Using the Job Demands-Resources Model.
Full text linkAlthough the construct of work engagement has been extensively explored, a systematic meta-analysis based on a consistent categorization of engagement antecedents, outcomes, and well-being correlates is still lacking. The results of prior research reporting 533 correlations from 113 independent samples (k = 94, n = 119,420) were coded using a meta-analytic approach. The effect size for development resources (r = .45) and personal resources (r = .48) was higher than for social resources (r = .36) and for job resources (r = .37). Among the outcomes and well-being correlates explored, the effect size was highest for job satisfaction (r = .60) and commitment (r = .63). Furthermore, moderation analysis showed that (a) concerning the occupational role, work engagement finds a low association with turnover intention among civil servants, volunteer workers, and educators; (b) collectivist cultural environments reported a greater association of feedback with engagement than individualistic environments; (c) the relationship between personal resources and engagement was stronger among workers with university degrees than workers with high school diplomas. Furthermore, the absorption dimension showed a lower effect with all variables under investigation than vigor and dedication
Salvemos la pesca artesanal! Resumen de la audiencia pública desde la sección V del Congreso de la República promovida por el senador Jorge Enrique Robledo
Full text linkComo mujer, estoy representando muy bien a mis pescadores porque sí sé qué es coger un anzuelo, sí sé qué es montarme en una lancha, en un bote de remos; sí sé qué es que un nailon me apriete y me rompa las manos; sí sé qué es oler a pescado y si sé qué es buscar 5 de mis pescadores en el mar sin que me los devuelva y 9 en la tierra sin tener resultado alguno; yo sí sé qué es ser pescadora y comparto con estas compañeras que hoy dejamos las faldas allá y trajimos los pantalones bien puestos. Yoanis de Ávila- ASOPLÁN.
De esta manera, Yoanis de Ávila iniciaba su intervención en la citada audiencia pública desde la sección V del Congreso de la República, promovida por el senador Jorge Enrique Robledo. Con estas palabras se dirigió ella a más de 700 organizaciones de pescadores el jueves 16 de febrero del presente año, reunidas en ese recinto con el fin de no permitir que, vía proyecto de ley, el gobierno nacional dé el golpe definitivo para acabar con la pesca artesanal en el territorio colombiano
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
