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
Structurally tailored hierarchical anode surface for selective inward lithium growth in lithium-metal battery
No full text학위논문(석사) - 한국과학기술원 : 기계공학과, 2021.2,[iv, 52 p. :]리튬-금속(lithium-metal)은 표준 수소 전극(standard hydrogen electrode) 기준 –3.04 V의 낮은 전기화학적 전위와, 상용 흑연 전극 대비 10배에 달하는 3860 mAh/g의 이론적 용량 밀도를 갖기에 이상적인 차세대 리튬 이차 배터리(lithium secondary batteries)의 음극 활물질(anode active material)로 주목받고 있다. 그러나, 리튬-금속을 음극활물질로 사용하는 리튬-금속 배터리는 리튬의 전착 및 탈리 과정에서 발생하는 수지(dendrite) 구조 형성으로 인해 상용화에 있어 어려움을 겪고 있다. 리튬의 전착/탈리 과정에서의 전류 밀도가 높을수록 리튬 수지 구조의 형성 시점과 성장 속도가 빨라진다는 점에서, 전극 표면적 극대화를 통해 전류 밀도를 낮출 수 있는 마이크로 혹은 나노 구조를 갖는 전극들이 제안되고 있으나, 마이크로 구조는 나노 구조에 비해 표면적이 작고, 나노 구조는 마이크로 구조에 비해 구조적 안정성이 떨어지며 구조 내부까지 리튬의 균일한 전착을 유도하지 못한다는 점에서 각 구조의 한계점이 분명하고, 최적의 구조 크기에 대한 연구결과가 제시된 바 없다.
본 연구에서는, 균일한 마이크로 패턴 내부 표면에 나노 구조체가 함유된 복합 계층구조 전극을 설계 및 제작한다. 마이크로 패턴은 광-리소그래피(photolithography) 및 전주 도금(electroforming)에 의해 높은 재현성과 패턴간의 균일성 및 형상변수 조절의 자유도를 갖도록 제작하며, 나노 표면 구조는 인가전압 및 할로겐 이온 농도의 조절에 따른 전착(electrodeposition)을 통해 다양한 형상 및 직경을 갖도록 제작한다. 평판 구조, 마이크로 구조, 나노 구조에 대한 반쪽-전지(half-cell) 실험을 통해, 마이크로 및 나노 수준에서의 구조적 최적화를 각각 진행하고, 최종적으로 본 연구에서 고안한 복합 계층 구조 전극의 제작 및 실험을 통해 쿨롱 효율, 율속 특성 및 수명 안정성을 개선한다. 다양한 형상 실험 비교를 통해 마이크로 구조는 리튬을 안정적으로 수용할 뿐만 아니라, 나노 구조체가 갖는 취약한 구조적 안정성을 보완할 수 있음을 설명한다. 한편, 나노구조는 넓은 표면적을 제공하여 리튬의 전착 및 탈리 과정에서 전류 밀도를 크게 낮추는 역할을 할 뿐만 아니라, 국부적 전기장 집중 효과를 통해 리튬이 마이크로 구조 내부에 선택적으로 전착되도록 유도함을 표면 구조에 따른 전류밀도 분포 해석 및 실험 결과를 통해 입증한다.한국과학기술원 :기계공학과
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

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.
