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
Dispelling the Myths Behind First-author Citation Counts
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
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
Similitude and Landslides Behavior for Shaking Table Test
No full text大地工程問題通常規模大，材料組成複雜，不容易利用全尺寸的現地試驗觀察破壞機制。透過模型相似律與問題的簡化，可以縮小尺度建立物理模型試驗，在1-g的條件下來觀察大地工程問題的破壞機制。本研究採用林美聆、王國隆於2009年9月於國家地震中心所進行之大型振動台試驗資料，由加速度反應、PIV影像分析以及標點位移量測，觀察邊坡受震反應，推測破壞時間。以有限差分軟體FLAC模擬邊坡模型受震反應，推測可能之破壞面位置，由應力路徑與加速度歷時推測可能之臨界加速度。利用建立之數值模型，針對大型振動台試驗模型與原型之模型相似性進行討論。
邊坡淺層崩滑時，滑動範圍僅發生在邊坡坡面，坡頂及坡趾並無明顯位移產生，試體內部加速度反應並不明顯。邊坡產生大規模深層塊體滑動時，坡頂及坡趾開始往下坡方向移動，坡頂後方產生裂縫，試體內部不同深度之加速度相位反應不同步。由標點位移量測定義當坡頂裂縫產生後，坡頂標點移動速度開始改變時之位移量為臨界位移量，當FLAC計算出邊坡模型之水平位移量達臨界位移量時，定義此時最大剪應變範圍為破壞面，其延伸至坡頂位置與影像記錄所量測到之位置相近。藉由Meymand（1998）所提出之模型相似律，可以由模型邊坡之試驗結果預測原型邊坡之受震反應。本研究利用數值軟體FLAC分別模擬大型振動台邊坡模型試驗，以及原型邊坡之受震反應，發現兩組邊坡之時間長度正規化相對水平位移變化以及剪應變分佈相當一致。因此，在不考慮邊界效應以及能量消散之情況下，可使用由邊坡模型試驗所建立之數值模型模擬現地邊坡受震反應行為。Geotechnical engineers usually encounter large-scale problems with complex material composition. Thus, it is hard to use full-size in-situ test to observe the failure mechanism. By law of similitude and simplification, small-scale model tests were established to simulate 1-g gravitational field. This study was according to the large-scale model slope shaking table tests of the model slope conducted by Lin and Wang in September 2009 at NCREE. The failure time was estimated according to the acceleration responses, particle image velocimetry (PIV) analysis, and marker displacement measurements. The failure plane was estimated from results of the finite differential numerical analysis. The critical acceleration was estimated based on stress path during loading. By using the established numerical mode, the similarity between model and prototype was discussed.
Shallow failure sliding occurred on the slope surface, no significant displacement on the crest and toe, and no obvious difference in acceleration responses were observed. As landslide occurred, the crest and toe started moving toward down-slope. The crack occurred behind the crest, and the acceleration response became shifted. After the crack occurred and the markers at the crest started moving rapidly, the critical displacement was defined by the marker''s horizontal displacement. The failure surface was defined by maximum shear strain distribution when the numerical model''s horizontal displacement was equal to critical displacement. The location of failure surface at the top of the slope is similar to the crack measured from image. According to the law of similitude proposed by Meymand (1998), the prototype seismic slope response could be predicted from model test. Based on results of numerical simulation of prototype seismic behavior, it was found that the normalized deformation and shear strain distribution were quite similar. Therefore, the numerical model established according to the slope model test could be used to simulate in-situ seismic slope response when boundary effects and energy dissipations were insignificant

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
