    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 link
    We 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 link
    We 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

    플라즈마 구동기를 이용한 저 레이놀즈 수 영역에서의 유동제어 연구

    학위논문(박사) - 한국과학기술원 : 항공우주공학과, 2015.8 ,[vii, 120 p :]유전체 장벽방전을 이용한 플라즈마 구동기는 펌프나 유동 이동용 파이프 없이도 벽면 유동을 발생시킬 수 있어 기존의 유동제어 장치가 설치되기 어려운 곳에도 상대적으로 간단하게 장착할 수 있다는 장점이 있다. 이 덕분에 최근 몇 년간 저 레이놀즈 수 영역에서 유용한 유동제어 장치로 연구되었으나 낮은 유동속도와 성능 예측이 어렵다는 단점으로 인하여, 실제 활용을 위한 연구에 있어서는 어려움을 겪고 있다. 본 연구에서는 플라즈마 구동기의 반실험적 추력 모델을 위해 추력기의 설계요소, 운용조건이 고려된 추력 식을 구성하였으며, 이를 본인이 측정한 결과와 기존의 실험결과 등과 비교해 검증하였다. 또한 이를 전산유체 해석과 결합하여 플라즈마 구동기에 의한 2차원 벽면 유동으로 나타내고 이를 실험결과와 비교, 검증하였다. 3차원 형태에 대해서는 플라즈마 구동기에 의한 와류 생성기를 구성하였고 반실험적 모델에 의한 와류 생성 결과와 실험 간의 결과를 비교하였다. 구성된 모델을 통해 복잡한 이온-전기장-유체 해석 없이도 플라즈마 구동기에 의한 유동변화를 나타낼 수 있게 되었고, 플라즈마 구동기와 적용된 시스템이 결합된 복잡한 상황에서의 유동변화를 상대적으로 쉽게 계산할 수 있게 하였다. 와류 발생기의 형태로 플라즈마 구동기를 구성하여, 앞서 언급한 모델을 활용해 플라즈마 와류 발생기의 구동 및 운용 조건의 변화에 대한 해석을 쉽게 수행하였다. 플라즈마 와류 발생기의 활용 가능성을 비유선형 물체에 발생하는 후류 박리에 의한 저항 감소를 통해 확인하였으며, 다양한 구동 및 운용 조건 관련 매개변수를 연구하였다. 매개변수에 의한 비유선형 물체의 공기저항 변화는 전산유체 해석과 풍동 실험을 통해 수행되었고, 최대 10%의 저항감소 효과와 두 방법간의 일치를 확인하였다. 또한 유동 가시화 실험을 통해 와류 발생기에서 발생하는 와류와 박리 억제를 확인할 수 있었다. 매개변수 변화에 따른 해석 및 실험 결과는 무차원 해석을 통해 플라즈마 와류 발생기의 성능에 민감한 요소의 변화에 따른 경향을 확인하였다.한국과학기술원 :항공우주공학과

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We 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 text
    In 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.
