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
Real-Time Fiber Diameter Measurement Technique and Refractive Index Profiles Measurement Technique Applied to Micro-Nano Optical Wires Fabrication
No full text當半導體元件愈來愈小，傳輸的速度愈來愈快，微小化的光通訊系統及光電基板可望成為未來發展的方向之一。我們實驗室以改良的微小化抽絲塔，在可控制的條件之下成功製作出數十微米至數百奈米等級的微奈米導光線。因應抽絲塔的製程需求，我們開發出一套即時直徑量測系統，用來即時檢測並對製程系統做調整。量測方法使用雷射側向入射、觀測散射條紋的方式，並對此量測方法的精確度做了驗證。此外，為了確認製造出的微奈米導光線之導光性質，有必要了解其纖核及纖殼的變化狀態。我們使用一個基於定量相位顯微術的方法，藉由觀察光纖側面亮場成像之方式，檢測光纖的截面折射率分布。基於此方法，可以了解光纖的性質，也對各種不同種類的光纖分別做了檢測及分析。With semiconductor devices become smaller and the transmission speed becomes faster, minimized optical transmission system and the optical integrated circuit are the candidates for future application and development. We utilized a modified-miniature fiber drawing tower to fabricate micro-nano optical wires (MNOWs) from few tens of micrometers down to few hundreds of nanometers scale under controllable conditions. For the necessity of the fiber drawing fabrication process, we develop a real-time diameter measurement system for in situ detecting and adjusting the fabrication parameters. The method is to pass a laser beam through a fiber and characterize its scattering pattern from which the diameter of the fiber is determined. The verification of accuracy and precision was also done. Furthermore, to confirm the light propagation property of the fabricated MNOWs, it is necessary to examine the variation of core and cladding. We utilized a method based on quantitative phase microscopy (QPM), which observe the bright field images of side view of a fiber to measure the refractive index profile along the cross section. From this approach, we can examine the fiber property, and measurements to a few kinds of fibers were done and analyzed.摘要 Ibstract IItatement of Contributions IIIontents IVist of Figures VIIist of Abbreviations XIIIhapter 1 Introduction 1-1 Motivation 1-2 Organization of the Thesis 4hapter 2 Fabrication of MNOW 5-1 Experimental Setup 5-2 Modified Multi-Stage Process for MNOW Fabrication 9hapter 3 Fiber Diameter Measurement 13-1 Overview 13-2 Principle 15-3 Experimental Setup and Measurement Scheme 21-4 Measurement Results and Discussion 31-4-1 Comparison Between Experimental and Simulation Results 31-4-2 Confirmation of the Measurement Accuracy and Precision 34-4-3 Real-time Measurement Results during Fiber Drawing Process 42-4-4 Discussion of the Measurement Limit 50-5 Summary 52hapter 4 Fiber Refractive Index Profile Measurement 54-1 Overview 54-2 Principle 56-3 Experimental Setup 60-4 Results and Discussion 63-4-1 Single Mode Fiber 63-4-2 Multi-Mode Fiber 72-4-3 Photosensitive Fiber 75-4-4 Erbium-doped Fiber 78-4-5 Tapered Fiber 83-4-6 MNOW from the Drawing Process 88-5 Summary 98hapter 5 Conclusion and Future Work 99-1 Conclusion 99-2 Future Work 100eferences 101ublications 10

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.
