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
"Chung San Kuan", a Special Group in the Northern Wei Bureaucracy
No full text拓拔氏的制度裏設有「中散」一職，是兩漢、魏晉，以及南朝的漢族王朝所沒有的官職。「中散」獨出現於異民族鮮卑拓拔氏所建立的國家，這種情況，對於政治制度的研究，或是對於中國史上異民族王朝的討論，都是一個值得深入省思的課題。北魏職官中的「中散」，起自太祖道武帝拓拔珪或太宗明元帝拓拔嗣，結束於孝文帝朝。翻閱中外史籍，在異民族王朝的統治之下，常有二元的政治社會存在，在政治制度上也常會出現二元體制。「中散」在史書裏雖以中國式的官名出現，但其原本是胡制；即使不然，也是異民族王朝在中國獨特設立的制度。於是乎，「中散」就在這樣的時空背景下應運而生。本文寫作的方式，首先討論「中散」一職的設立、品階與廢置、近侍與職掌、官號與散官、身份與遷官等；次敘中散、主文中散、奏事中散、侍御中散四類中散官職的性質。各種中散，總稱中散官，在北魏內廷職官中自成一個系統。但中散名稱之由來，或是游牧部族制裏的職官，取中國之字義而漢譯成中國式的官名。其名稱則因職官性質近於散官，並在禁中服務，故取名中散。中散官之充近侍，猶如漢代的郎官，一則因中散官與漢帶郎官之發展、分化過程相似，說明了官制發展的原則性；其次，這兩種職位的出現可以說明職官發展的原則，是由宮官轉向府官發展
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
