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
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
“One of the Most Intensely Exciting Secrets” : The Antarctic in American Literature, 1820-1849
No full textThis study examines a small body of 19th-century American literature about the Antarctic: Adam Seaborn's (pseud.) Symzonia (1820), Edgar Allan Poe's "MS. Found in a Bottle" (1833) and The Narrative of Arthur Gordon Pym (1838), Peter Prospero's (pseud.) "The Atlantis" (1838-39), and James Fenimore Cooper's The Monikins (1835) and The Sea Lions (1849). These were written in a transitional phase in the history of the Antarctic. At the start of the period, the region was almost completely unknown. Towards the end of the period, however, the region had been mapped in its essence, and the existence of an Antarctic continent had been verified. For complex reasons, the region came into cultural focus in the U.S. during the 1820s to 40s, culminating in the first major American scientific expedition in 1838-42 to explore the South Seas and the Antarctic. The study is primarily historical, tracing ideas to their historical contexts in order to determine what these authors used the unknown space of the Antarctic for. These texts were written in imaginative response to contemporary notions of the Antarctic, which is reflected in the mode of representation. The literature is in the mode of speculative fiction-most of texts imagining a tropical, inhabited Antarctic-up until the region is explored, at which point it turns to realism. The texts fall into three categories: the utopian, liminal, and realistic. The utopian texts-Symzonia, The Monikins, and "The Atlantis"-are works of social criticism, using the blank space of the Antarctic to treat a diverse range of issues, including politics, evolutionary theories, race, and gender. Poe's "MS" and Pym represent the liminal category; they dramatize the anticipation of an imminent Antarctic discovery, narrating up to a point of revelation, only to stop short. The Sea Lions is the only realistic text, coming after the Antarctic is explored. Here the knowledge of the Antarctic has solidified into the environment we know today, but with religiously symbolical overtones.
'The awful parenthesis' : Ethics and aesthetics in De Quincey's murder essays
No full textThomas De Quincey's series of three essays under the general title 'On murder considered as one of the fine arts' (1827-1854) has delighted and puzzled readers and critics for its iconoclastic representation of violent material. Whereas the first two instalments are satirical and comical, clearly parodying amoral, disinterested, approaches to aesthetics and ethics, the last one is more problematic as it seems to embody precisely those approaches. In order to bridge the theoretical gap between the first two and the third, the argument here is that an earlier essay, 'On the knocking at the gate in Macbeth' (1823), should be seen as part of the series, based on similarities in form and content. In the course of these four essays, De Quincey creates a metafictional discussion of the relation of ethics and aesthetics that has broader application to later emanations of crime writing as well
