Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
自発的脳活動に見られる遷移ダイナミクス(非線形振動子系の物理学 : 現代的問題とその解析,基礎物理学研究所研究会YITP-W07-02)

<Articles>Labor Struggles and Ethnic Conflict in 1905 Baku
No full text個人情報保護のため削除部分あり一九〇五年にバクーで起きたムスリムとアルメニア人の二度の民族衝突は、ロシア政府の煽動による面のみが強調されがちである。確かに、二月の衝突はロシア政府、および政府と結託したムスリム「ゴチュ」層の主導で始まった。しかし八月衝突にはムスリム労働者も参加している。五月から八月にかけて、ムスリム/不熟練労働者は、労働運動を展開する中で、一二月協約の成果を得ていたキリスト教徒/熟練工との溝を深めていった。民族と労働階層の重なりに加え、社民系二党派の対立もこの亀裂を広げている。八月衝突の直前には、熟練工/アルメニア人組織の妨害によって、不熟練労働者中心のゼネストが失敗している。ムスリム労働者の労働運動に対する不満は、モッラー等の宣伝によってアルメニア人に向けられる。八月衝突は、労働者階層対立の具現という側面も持っていたのである。Muslims and Armenians twice battled in 1905. Russian ethnic policies have been perceived as generating this conflict, and indeed the initial February clashes were initiated by officials and impoverished Muslim land-owners (gochu). By contrast, unskilled Muslim workers participated in the August disturbance. These workers continued their strike after May Day, thereby heightening tensions between them and the skilled Christian workers who had been generally satisfied with the December concessions. Thus an ethnic division paralleled a labor dispute which was exacerbated by the split between Bolsheviks and Mensheviks
Variations on the Author
Get PDF“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
<Articles>The Gurian Seasonal Workers in Batoum : Labor Movement and Ethnic Factors in 1905 Revolution
No full text個人情報保護のため削除部分あり西グルジアの石油積出港バトゥミでは、スターリンの関与の下で死者十数名を出した一九〇二年三月のゼネストを契機に、攻撃的労働運動が展開する。ロシア社会民主労働党バトゥミ委員会は、グルジアのグリア地方出身の出稼労働者を中心勢力として、〇五年革命以前から「独裁的」権威を誇った。実質的チロル容認と、出稼ぎグリア人の同郷人集団の結束がその背景にあった。バクーのアルメニア人虐殺以来、ザカフカス全域で民族対立が重大化し、委員会もグリア人以外からは民族的偏りを従来以上に警戒される。しかし「グルジア人」としての民族的利害ゆえにグリア人は委員会を支持したわけではない。「マルクス主義的党派がグルジア人の民族的利害を吸収した」という通説は、むしろ同時代の他民族の目から見た限りで正当化される議論だったのである。Georgia was peculiar in Tsarist Russia in that, though most Georgians are peasants, the Marxist party Menshevik was so powerful that it became Georgian "national party". The starting point of Menshevik hegemony was the peasant movement in western Georgia, especially Guria province. Gurian peasant movement was tightly connected with the labor movement of Batoum (Batumi), the oil port of neighboring Achara province, through migrant workers. Achara province was annexed by Tsarist Russia from the Ottoman empire in 1878. Acharans in village were Georgian in language, but Muslim in religion, in contrast that other "Georigians" were orthodox. So Gurian (=Georgian) workers, which had become the main part of migrant workers in Batoum, had little ties with Acharan peasants. In Batoum aggressive labor movement flourished, especially after the general strike (March 1902), which took place under the engagement of Stalin and witnessed over 15 workers killed. This strike also caused the send-back of hundreds of Gurian migrant workers, who became one of the initiators of Gurian peasant movement. Henceforth the Batoum committee of the Russian Social Democratic Workers' Party enjoyed high authority and powers over the Batoum workers, which was sometimes seen as even "dictatorial" before and during 1905 revolution. The main participants of the committee were Gurian migrant workers. The main weapons were terrorism, which was seen de facto tactics of the committee, and the provincial ties of Gurian workers. The Armenian massacre in Baku (February 1905) had increased the influence of ethnic problematics in Transcaucasia. The committee was also seen as ethnically impartial in the eyes of non-Georgians. In fact, Armenian workers and Georgian workers had conflicted several times before 1905. The ethnic interests of "Georgians", however, did not cause the authority of the committee among Gurians. In Poti, a neighboring port of Batoum, Gurian workers and Mingrelian workers conflicted, both of which were seen as sub-units of "Georgians". Moreover, Acharans, or "Muslim Georgians" generally stood in opposition to revolutionary movements, which were mainly taken part in by Gurians and other Christians. The menace of the massacre was at last taken over, when an Acharan influential bek compromised to the committee, seeing its substantial power. The committee also took actions to Armenians, who had a strong nationalist-revolutionary organisation. Therefore, the Batoum committee can be said to have been de facto Gurian organisation, not Georgian, though it insisted on its internationalism. We need not to overlap Georgian national interests to the hegemony of the Batoum committee. The commonly accepted theory has supposed that Marxism overlapped the Georgian national interests. But this theory rather reflects the non-Georgian view in that era. The ethnic factors, as well as class factors, should not be seen as "the hidden essential determinant"
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
