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
The magnitude of placebo analgesia effects depends on how they are conceptualized
No full textObjective: Placebo effects are usually calculated as the difference between placebo treatments and no treatments. Recently, placebo-like effects have been investigated using open and hidden administrations of active treatments. The aim of the study was to directly compare the two types of placebo effects and examine how they are influenced by personality traits. Methods: In a within-subject, randomized, blinded, balanced placebo trial design study with 48 healthy volunteers, we compared placebo and placebo-like effects and tested if expectancy, absorption and suggestibility correlated with these effects. Subjects completed the Tellegen Absorption Scale and the Sensory Suggestibility Scale, and pain was induced by injections of hypertonic saline into the masseter muscle. Participants received four injections of hypertonic saline with lidocaine or matching placebo in randomized order: open treatment, hidden treatment, placebo and control. The placebo effect was defined as the difference in pain between the placebo and the control condition and the placebo-like effect as the difference in pain between the open and hidden condition. Results: Placebo effects were significant both in the traditional paradigm: mean placebo effect AUC 1626 mm2 (95% CI 958-2293) and the open-hidden paradigm: mean placebo-like effect AUC 801 mm2 (95% CI 134-1469), but there was a significant difference between the magnitude of the two effects (p = 0.049). Absorption and suggestibility did not predict the placebo or the placebo-like effect. Estimated expected pain relief correlated with placebo effects but not placebo-like effects. Conclusion: The magnitude of placebo effects differs depending on how they are conceptualized and calculate
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
