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

The evolution of efficient compression in signaling games
Get PDFConverging evidence suggests that natural language meaning systems are efficient by jointly maximizing cognitive simplicity and communicative informativeness. Comparatively less is known about how languages might optimize over time for communicative efficiency. Our goal in this paper is to use minimal dynamic models to give a high-level description of the evolution of efficient meaning systems. To do this, we provide a model of emergent communication combining evolutionary game theory with a recent information theoretic account of efficiency in semantic systems. We perform simulations of adaptive dynamics requiring minimal assumptions about agents’ cognitive resources, and observe that emergent languages converge near the achievable bounds of efficient compression. This unifies existing accounts of communicative efficiency with minimalist accounts of how meaning can emerge ex nihilo

A Most Wanted Man By Anton Corbijn: Poetics Of Imprisonment
Get PDFAnton Corbjin’s A Most Wanted Man is an exploration of the spy genre with a postmodern bent, in which the usual tropes such as escapism, exoticism, and technological and political thrill are constantly interwoven into a kind of irony in narrative programs that plays on the subject’s ideas about spies and terrorism. In A Most Wanted Man, viewers are forced to think critically about aesthetic experience in order to find answers to the film’s implied questions; I will argue that a poetics arises from recursive imagery and gives weight to the film’s issues regarding a core, psychoanalytic-existential lack. This lack appears in the form of desire for control within a global power structure and addiction. Rather than giving physical violence any screen time, the film exploits alternative (or perhaps underlying) anxieties to deal with politics: ideology, sex, and addiction bloodlessly drop viewers into thriller territory, exposing the anxieties involved in what we might call ‘post-terrorism.’ Recursive filmic images of “arrest,” or brief lapses in the action which function to anchor NPs to one another, offer certain releases from A Most Wanted Man’s dystopia while simultaneously developing a poetics, through patterns, rhythms, and interweaving with NPs. Recursive images of alcohol and cigarettes will be the focus in this paper, because of their obvious recursive role in the film, but also because smoking is often a universal proxy to psychological issues. During a period of significance for the poetics of recursivity, we observe a shift in Gunther’s cynical, narcissistic, and self-destructive personality. I will then use this aspect of the recursive poetics to psychoanalyze the nature of subjectivity construction in film
Modals in Natural Language Optimize the Simplicity/Informativeness Trade-Off
No full textThesis (Master's)--University of Washington, 2022The meanings expressed by the world’s languages have been argued to support efficient communication. Evidence for this hypothesis has drawn on cross-linguistic analyses of vocabulary in semantic domains of both content words (e.g. kinship terms as shown in Kemp and Regier [2012]; color terms as in Zaslavsky et al. [2018]) and function words (e.g. quantifiers as in Steinert-Threlkeld [2021]; indefinite pronouns in Denic et al. [2020]) approaching the hypothesis concretely in terms of a trade-off between simplicity and informativeness. I apply the analysis to modals (e.g. can, ought, might). Two proposed universals in this domain from Nauze [2008] and Vander Klok [2013] are used for generating many artificial languages with varying degrees of quasi-naturalness as a proxy for natural data. A computational experiment shows that the Vander Klok universal picks out the optimal solutions to the simplicity/informativeness trade-off, suggesting that efficient communication is a leading explanation for constraints on modal semantic variation
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
