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
Stable Laws for Chaotic Billiards with Cusps at Flat Points
No full textWe consider billiards with a single cusp where the walls meeting at the vertex of the cusp have zero one-sided curvature, thus forming a flat point at the vertex. For Holder continuous observables, we show that properly normalized Birkhoff sums, with respect to the billiard map, converge in law to a totally skewed -stable law.
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

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
A Dialogue Between Contemporary Kunqu Opera and Ming-Qing Chuanqi: Considering the Case of the Playwright Zhang Hong
No full text當代崑劇編劇張弘與著名小生石小梅夫妻，共同創造了多個當代崑劇傑出人物，《白羅衫》徐繼祖尤為代表。本論文以張弘《尋不到的尋找》一書所收自選八部崑劇劇作為研究主體，展開對於「崑劇創作」的研究，焦點集中於當代崑劇和其源頭明清傳奇之間的對話。
以張弘為研究對象，一則因八部作品涵蓋了當代崑劇對傳奇改編的各種型態，足以與當代各類型崑劇創作相互比較。更深層的原因是張弘有清晰的創作意識，明確知道自己不只是長篇傳奇的剪裁者，他有意識的利用古典傳奇進行當代崑劇創作。傳奇在他的崑劇中並非戲中戲，他通過文本互涉、對話關係進行情緒深掘、思想轉折，進而塑造人物、創出新作。古典傳奇、古代編劇與當代張弘之間的三層對話關係，在當代崑劇劇壇特別值得重視。
傳奇與崑劇之重疊與分野，學界已有辨析成果，但在創作領域仍嫌混淆。評論者常以傳奇審美標準求之於當代崑劇，創作者則又多忽視崑劇與傳奇密不可分的關係，直以板腔體編劇觀念進行崑劇創作，敘事結構與曲牌唱腔未能彰顯崑劇本質與文人氣韻。本論文從張弘切入，從崑劇與傳奇之對話關係彰顯張弘清晰的崑劇創作觀念，所欲研究者實不限於八部劇作。本論文隱性的研究範圍包羅甚廣，當代崑劇創作的現況實為本文之背景、參照、對比，甚至是本文寫作之動機。研究層次有三：(1)、張弘的崑劇創作意識以及與傳奇的對話關係，(2)、檢驗張弘創作理念是否有效落實，(3)、張弘在當代崑劇創作界的對照，甚至指引意義。As a couple, the contemporary Kunqu Opera playwright Zhang Hong and the
famous Xiaosheng (the young man’s role) Shi Xiaomei have created many outstanding
roles of contemporary Kunqu Opera, of which Xu Jizu of “Bailuoshan” (The white
coat) is the most representative. This study conducted a thorough investigation of
Zhang Hong’s “Seek for the Unseen” (a collection of eight Kunqu Opera plays),
to research Kunqu Opera writing, especially focusing on the dialogue between
contemporary Kunqu Opera and Ming-Qing Chuanqi.
This project has two reasons to put emphasis on Zhang Hong: one, his eight
plays cover every type of adaptation from Chuanqi to Kunqu Opera; they could
compare with all the other types of contemporary Kunqu Opera. Second, and more
deeply, Zhang Hong has a clear writing consciousness. He knows exactly that he is
not just a tailor of the extensive Chuanqi stories, but also uses Chuanqi to frame his
Kunqu Opera writing. Chuanqi is not only “a play within a play” in his Kunqu Opera.
He creates new plays and roles through intertextuality and interlocution, and digs out
deeper emotions and refracted thoughts. The three-way conversation of traditional
Chuanqi, traditional playwrights, and contemporary Zhang Hong is worth our respect
and attention.
The overlapping or division of Kunqu Opera and Ming-Qing Chuanqi has
been analyzed in the academic field; however, treatment of the field of writing is still
in chaos. Kunqu critics often turn to Chuanqi for aesthetic standards. Playwrights
frequently ignore the close partnership of Kunqu Opera and Chuanqi; they just use the
Banqiang style to write Kunqu Opera. But such a narrative structure along with qupai
singing cannot highlight the basis of Kunqu Opera and its deep intellectual philosophy.
This project is based on Zhang Hong, and then emphasizes his Kunqu Opera
writing method from the dialogue between Kunqu Opera and Chuanqi. Furthermore,
this study aims at his eight plays as well as at contemporary Kunqu Opera. The
chaos of contemporary Kunqu Opera writing is the background, reference, term of
comparison, and in addition, the motivation of this study.
Three issues are related to this project: first, Zhang Hong’s creative
consciousness regarding Kunqu Opera, and his dialogue with Chuanqi; second,
assessing the effectiveness of Zhang Hong’s writing ideas; third, the significance of
Zhang Hong in contemporary Kunqu Opera
