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
<Articles>A Study of Miyata-no-sho (宮田庄), Tanba-no-kuni (丹波国)
No full textこれまでに行われて来た庄園の個別的研究の大半は、東寺・東大寺その他の大社寺庄園であり、院領、摂関家領の如き公家領庄園についての個別的研究は乏しい。しかしこのことは公家領庄園の研究の重要性が少いことを示すものではない。公家領庄園に関する史料は大社寺領庄園程豊富に残存していないが為に外ならない。その公家領の中でも、この近衛家領丹波国宮田庄は、史料が比較的まとまっているので、当庄を中心にして、公家領庄園についての一つのデーターを提供したいと思う。しかし史料の制扼もあるので、主として当庄の鎌倉時代後半期の情勢について述べることにした。Much of the study so far done on Shoen (manor or manors, 庄園) is in regard to those of large temples or shrines such as Toji (東寺) and Todaiji (東大寺), and little of them in regard to those of courtiers. This means that historical sources so far found were in favor of the study for the manors of temples or shrines, but not that the study of courtiers' manors was thought to be less important. Among courtiers' monors, Miyata-no-sho (宮田庄), Tanba-no-kuni (丹波国) owned by the Konoe (近衛) family seems to afford rather comprehensive sources. Thus the author intends to describe the situation of courtiers' manors, especially that of Miyata-no-sho during the latter part of Kamakura (鎌倉) period
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
