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
Translating alloy using Boolean circuits
Full text linkThesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2004.Includes bibliographical references (p. 71-72).Alloy is a automatically analyzable modelling language based on first-order logic. An Alloy model can be translated into a Boolean formula whose satisfying assignments correspond to instances in the model. Currently, the translation procedure mechanically converts each piece of the Alloy model individually into its most straightforward Boolean representation. This thesis proposes a more efficient approach to translating Alloy models. The key is to take advantage of the fact that an Alloy model contains patterns that are used repeatedly. This makes it natural to give a model a more structured Boolean representation, namely a Boolean circuit. Reusable pieces in the model correspond to circuit components. By identifying the most frequently used components and optimizing their corresponding Boolean formulas, the size of the overall formula for the model would be reduced without significant additional work. A smaller formula would potentially decrease the time required to determine satisfiability, resulting in faster analysis overall.by Samuel Isaac Daitch.M.Eng
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
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
Disciplined by democracy: moral framing and the rhetoric of Red Letter Christians.
No full textUniversity of Minnesota Ph.D. dissertation. March 2010. Major: Communication Studies. Advisor: Kirt H. Wilson. 1 computer file (PDF); iv, 219 pages.In this dissertation I study both the textual reception and rhetorical production strategies of the Red Letter Christians, a discourse community whose identity is linked to these very same strategies. I contend that the Red Letter Christians engage in biblical reading strategies that make them distinct from other politically liberal or progressive religious groups. The Red Letter Christians employ a moral frame based on their particular reading of the Bible. Embedded in the notion of "conservative radicalism," such a moral frame asserts a dedication to timeless principles and truths authenticated by the gospel accounts of Jesus while it simultaneously upholds a passionate defense of social justice and the activist need to engage in political action in the present. Such a moral frame is biconceptual, expressing both conservative and progressive dimensions of moral social action. Due to the biconceptuality of the Red Letter Christian moral frame, Red Letter Christians often stress the importance of humility and non-partisan dialogue. Critics of the Red Letter Christians from both the political left and the right argue that such discourse is often incomprehensible and obfuscates the political positions the group defends in their rhetoric. I assert that in spite of their common reception as a religiously liberal group, the Red Letter Christians offer a model of discourse that at its best authenticates and otherwise justifies a model of post-partisan discourse that re-imagines religion's role in public political discourse.Boerboom, Samuel Isaac.
