No full textToward a New Civilization: The Universal and the Particular in the Early Thoughts of Li Dazhao
No full text民族構建與文明再造是清末以降許多中國知識份子的關懷所在，本文探討了1914至1918年間，它們如何現身於李大釗為謀「民族之復活」而發展的一套文化論述。具體而言，本文追溯李氏如何從「風俗保群」論出發，進而提出「造可愛之國」的課題及「青春中華」的理念，最終抵於「第三文明」的主張。本文指出，在他深受傳統影響的「青春」宇宙觀籠罩下，李氏發展出一種「普遍」與「特殊」相互交融的視域，進而將上述兩種關懷結合為一體兩面的追尋，最終並以超越西方主導的19世紀文明模式、創造具有社會主義內涵並調和了東西文明特質的「第三文明」，作為人類共同致力的目標，以茲解決現代世界的危機。本文強調，第三文明論雖有重大政治意涵，亦受到歐戰與俄國革命的影響，但它不能被化約為單純的政治性建構，反而突顯了「文明再造」的思考所涉從宇宙觀、個人觀、文化觀到歷史觀的複雜議題。「文明」固然可被本質化成為標示身份認同的符碼，亦可被援為民族國家的正當性基源，但在李氏那裡，它最突出的意義並不在此，而在於作為一種認識世界、改變世界的批判性範疇。對他而言，普遍未必與特殊衝突，而真正具普遍意義的20世紀新文明（亦即第三文明），必須經由東西各民族在自己的傳統基礎上，通過東西文明的匯通始可得見。李氏最初即是透過第三文明的視域，迎向革命的選項。可是，他將事物的普遍性建立在特定的宇宙論之上，以及他始終無法具體說明如何調和東西文明──這兩個事實，使得「靈肉一致」的文明理想，在理論與實踐上皆面臨了困境，最終只能如梁漱溟對他的批評那般，「俟諸未來」。他因而留下這樣的問題：在革命過程中，究竟有什麼資源，足以阻擋這個理想不異化為政治動員的工具？Nation-building and reconstructing the Chinese civilization had captured the most vehement imagination of many Chinese intellectuals since the late Qing period. This article explores how these were unfolded in the cultural discourse that Li Dazhao developed with a view to rejuvenate China during his pre-Marxist years (1914-1918). Highlighting the cosmological underpinnings of Li’s thoughts which he derived from the Chinese traditions, the article attempts to reveal the ways how the two concerns were integrated into one under a vista fusing the universal and the particular, and eventually led to the search for a “third civilization.” Taking shape under the influences of WWI and the Russian revolutions, Li’s concept of the “third civilization” was politically significant, in that it was posited as an alternative to the 19th-century Eurocentric model of civilization in the global project to resolve crises faced by China and the world. However, it should not be reduced and purely taken as a political concept, for it is emanated from a whole complex of ideas about individual, culture, history and the universe. “Civilization” may be essentialized to identify one’s identity, or posed as the legitimating principle of a nation-state. Yet in the case of Li Dazhao, the most prominent significance of civilization lies in the fact that it is a critical category to interpret and to change the world. For him, universality and particularity related to each other in a dialectical way, and the genuinely universal civilization in the 20th century could only arise from crossing the barriers of and fusing the various cultures/ civilizations from the East and the West. It was through the vision of the “third civilization” that he first discovered revolution as an alternative. Still, given that his conception of universality was grounded on a specific and culturally- bound cosmology and that he never confronted the substantial problem of how to assimilate Eastern and Western civilizations into a harmony whole, the civilizational ideal about the unity of soul and body that he proclaimed for the future is oftentimes hard to be reified. He thus left the question unanswered: in the process of a revolution, what resort would there be to prevent the ideal from being reduced into a tool of political mobilization
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
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
