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
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
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
Color and Culture: Mondrian and the Call to Order in Postwar Paris
No full text蒙德里安常以垂直、水平的線條交錯，部分平面塗上紅、黃或藍色，加上黑、灰、白之間的色調。他強調新造型藝術要在物質氛圍中實現，重視真實世界的內容。他不斷嘗試結合繪畫與音樂、建築，指向巴黎都會生活的內容，包含視覺經驗的街景、海報、櫥窗等，與聽覺經驗的新聲音、新節奏。第一次大戰後十年之間，他遭逢巴黎的文化民族主義—「回歸秩序」的思潮提倡古典主義線描與民族音樂。蒙德里安的色彩與音樂理論顯然回應文化同一性的議題，但目前歐美學界尚未有相關的深入研究。本文重新閱讀蒙德里安的藝術理論，分析他在1911－1930年的色彩與線條的實驗，以及相關的巴黎藝術評論，歸納他在此期的作品特質：色彩在構圖上的主導地位，以及色彩與聲音對應，作為結合繪畫與音樂的主要途徑。他以色彩與聲音的組織關係，呈現綜合藝術的新精神，追求秩序與自由的均衡，他的巴黎時期作品具有明確的都市規劃構想與國際主義特色。Mondrian’s work features interwoven vertical and horizontal lines, and rectangle surfaces colored in red, yellow, black, gray or white. He promoted Neo-plastic art to be realized in material environment, and transferred content from the real world. He continuously experimented in painting the fusion of musical and architectural elements, which embodied the urban life of Paris—visual experiences of streets, posters, shop windows, and acoustic experience of new sounds and rhythms. During the decade after World War I, he confronted the cultural nationalism in Paris, formulated by Call to Order with an emphasis on classical linearity and national music. Mondrian’s theories of color and music evidently respond to the issue of cultural identity. However, the question has not been fully investigated to date. The present essay offers a pluralist analysis of his experiments in color and line during the years 1911-1930, and contemporary art criticism. The author contends that Mondrian’s postwar work is based on the determinant role of color in composition, and the correspondence between color and sound is construed in order to combine painting and musicality. He conceived organized relationships of color and sound as the new spirit of the new art of synthesis or synesthesia, balancing rder and freedom. His Parisian work is characterized by an ideal of urban planning and internationalism

Get PDFWe 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
