    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    非流暢性要因としての同音誤字が文章理解に及ぼす効果

    文章中に含まれる一部の文字を薄い色で表示したり読みにくいフォントを使ったりすることによって,文章の内容記憶に良い影響を与える「非流暢性効果」の存在が多くの先行研究で示されている.しかしながら,従来の研究で取り扱われてきた非流暢性は,ほぼ全てが視覚的な困難に基づく非流暢性であり,それ以外の要因に基づく非流暢性の影響に関する研究は極めて少ない.本研究では,文章中に含まれる一部の文字の意味認知における非流暢性が与える影響について検証する.具体的には,正しい読みで読むことができるが誤った漢字である「同音誤字」を含めることが文章理解に与える影響について実験を行い調査した.その結果,同音誤字は文章の内容記憶にむしろ負の影響を与え,特に作業記憶容量が多い人にとってその影響が強いことが示された.Many previous studies have shown the existence of the “disfluency effect”, in which the use of a light color or a difficult-to-read font for some of the characters in a sentence has a positive effect on the memorization of the content of the sentence. However, almost all of the disfluency effects dealt with in previous studies were based on visual difficulties, and there have been very few studies on the effects of disfluency based on other factors. In this study, we examine the impact of difficulties in recognizing the meaning of certain characters in a sentence. Specifically, we conducted experiments to investigate the impact of including “homophonic Kanji errors” - A kanji that can be read with the correct pronunciation but is not correct in terms of meaning - on sentence comprehension. The results showed that homophonic Kanji errors had a negative impact on sentence comprehension, and that this impact was particularly strong for people with high working memory capacity

    Dispelling the Myths Behind First-author Citation Counts

    We 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
