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
Using wikis to support learning in post-secondary economics
No full textWikis are part of what is known as Web 2.0, or the read-write web, describing technology that have the potential to provide learners with tools that promote knowledge building through collaboration, social negotiation, and the reviewing and revising of ideas. When building a wiki, learners engage in a process of forethought, performance, and reflection, requiring that they be cognitively active with the learning material and carefully evaluate the accuracy of their understanding. This study examined the effects of contributing to a wiki combined with varying levels of pedagogical support using a 2 x 2 factorial design: Wiki (no-wiki / wiki) x Pedagogical Support (low / high). The sample consisted of 98 students in 4 sections of an introductory macroeconomics course at a large urban technical college in western Canada. While there is still much to understand regarding the impact of using wikis to support and foster meaningful learning the results of this study produced several important findings and practical implications. The results found that while there was no significant difference between wiki-users and the control group for achievement and overall perceived course effectiveness, there were advantages ascribed to the wiki groups. With respect to motivation, the results found that wiki-users coupled with higher levels of pedagogical support rated intrinsic goal orientation, task value, and self-efficacy significantly higher than the control group. When comparing the two wiki conditions it was found that learners in the wiki high pedagogical support condition rated task value significantly higher than those in the wiki low pedagogical support condition though with small effect sizes. Finally, preliminary descriptive data yielded profound differences between the two wiki groups with regard to their primary intention: collaboration. High levels of support appeared to stifle dialogue. Differences in how learners approached the task of building the wiki under different levels of pedagogical support were observed suggesting that even in a flexible, learner controlled environment, the instructor's suggested structure will have a large impact on how the tool is used. Implications for practice and future research are discusse
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
