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
<Article>The Revolts of Shezei 社賊 and Tuzei 土賊 during the Late Ming and Early Qing Period
No full text個人情報保護のため削除部分あり本稿は、明末清初の時期、広東珠江右岸デルタ地帯で展開された社賊、土賊の反乱の性格究明を直接の課題としている。社賊、土賊の反乱は、ともにに対する抵抗運動としての性格をもっており、なかでも社賊の変は郷村在住のに重大な打撃を与え、郷村をその内部から崩壊させた。この社賊の変は、従来、奴僕の身分解放運動として扱われてきたが、検討の結果、それが奴僕・佃僕を主体とする私的隷属民及びその他の郷村の下層民衆から構成されるとともに、次のような複合的な性格を保持していたことが明らかになった。第一に、主家の身分支配の打破を志向した奴僕・佃僕を主体とする私的隷属民の闘争の側面であり、第二に、利益を独占して、郷村の再生産機能の維持に努めない「富室」に敵対する側面である。更に第三点としては、地主・佃僕間の生産関係上の矛盾の激発としての抗租の側面が摘出された。以上の諸側面を内包しつつ、社賊はと対立・抗争を繰り広げたのである。This article aims to make clear the characters of the revolts of Shezei and Tuzei which took place around the right part of the Zhujiang 珠江 Delta during the Late Ming and Early Qing period. Both the revolts of Shezei and Tuzei had the character of a resistance against the xiangshen 郷紳 or gentries. Especially, the revolt of Shezei seriously damaged the gentries and destroyed the villages. Though the revolt of Shezei has been considered as a liberation movement of the nupu 奴僕 (bond servants), the examination clarified two points. 1) The rebellious people were composed not only of the nupu (private subordinates), but also of the dianpu 佃僕 (field servants who were private subordinates similar to the nupu) and also of the other lower class of inhabitants in the villages. 2) The character of this revolt was the composite of three aspects as follows. A) The struggle for the status liberation against their masters by those such as nupu and dianpu. B) Hostility against the rich families which neglected the reproduction and monopolized the profits in the villages. C) The struggle against the rent as a conflict between the dianpu and the landowners. So, the revolt of Shezei countered the xiangshen, involving the various classes and comprising the manifold factors, which have not been clarified
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
