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
Communication in A Visual Mode: Papal Apse Mosaics
Full text linkApse mosaics are a form of visual communication employed by popes throughout the Middle Ages, from the sixth through to the thirteenth centuries. This essay examines the nature of this visual mode and the means by which viewers could understand it. A theory of viewing widely attributed to Pope Gregory I (590–604) is shown to be especially pertinent to early medieval apse mosaics and to the twelfth-century mosaic in the apse of S. Maria in Trastevere. The apses of thirteenth-century popes display a new, more explicit approach to visual messaging that required less interpretive effort by the viewer. Two mosaics made at the end of this century were signed by the artist who made them. The emergence of the artist as a competing author of the image diminished the utility of this form of papal visual communication, which immediately fell out of use
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
The Image of a Building: Santa Maria in Trastevere
Full text linkBuildings can only be seen through images, including sensory impressions (perceptual images), views created by artists and photographers (pictorial images), the analytical graphics of architects (analytical images), and now, digital means of representation. This article is concerned with another level of image: the themes or metaphors the building was intended to convey (intended images); the image projected by contingent factors such as age, condition, and location (projected images), and the collective image generated by the interaction of the building’s appearance with the norms and expectations of its users and beholders. The Roman church of Santa Maria in Trastevere is taken as a case study. Its collective image among a cyber community of contemporary tourists is compared to its intended images in the twelfth century, when it was erected, and in the nineteenth century when it was effectively remade. The role of the image in constituting communities of users and viewers is foregrounded
