    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

    近年來全球有多起大規模的的天然災害發生,其中又以無預警的大規模地震發生次數最為頻繁,而橋梁除了日常的交通運輸作用外,在災害發生時亦是影響救災效率、人員疏散、物資運送的構造物;因此期望相關單位能在災前對橋梁做的補強評估中,可以藉本研究快速得到針對橋梁墩部的補強費用的的金額範圍。 本研究利用易損性曲線之成果來推估橋梁墩部補強費用,從「單位橋面板所需橋墩補強費用」著手做深入的討論,擬定出一套研析的流程方法,這過程會使橋梁墩部補強總費用具有更詳細地考量實務的狀況以及現實條件。因此本研究訂定出一橋梁墩部補強費用期望值模型,用以估計橋梁墩部受地震破壞後之補強費用期望值。其中因子包含考量橋梁個階段破壞機率值的橋梁易損性曲線,及透過專家問卷方式取得之橋梁墩部在各破壞階段的單位補強費用範圍,最後乘上符合條件之橋梁橋面板總面積,即可得到橋梁墩部補強費用期望值。 亦使用工程承受災害之風險評估輔助分析系統所分析出之新北市橋梁風險排序,套入到本研究計算出符合條件的新北市17座橋梁墩部的補強費用期望值,即可供橋梁相關單位參照使用。The world have occurred many natural disasters on a large scale in the recent years. The earthquakes without any warning have occurred frequently in natural disasters. And the bridge is not only used to transport, but also affect the relief efficiency, evacuation. Therefore, we expect the government can use this research to get repaired cost of the bridge pier rapidly in maintenances. This research will use fragility curves to estimate repaired cost of the bridge pier, the repaired cost of the unit of bridge slab is the object of intensive study. We will create the process for this research. This research would fulfill realistic situation even more by the process. And we will establish the expectation model of repaired cost of the bridge pier. This expectation model is used to estimate repaired cost of the bridge pier by earthquakes. First, we will use fragility curves of bridges to get the failure probability of the damage state. Second, we through the expect questionnaires to get repaired cost range of the unit of bridge slab in the damage state. In the end is multiplied by the total area of the bridge slab which comply the conditions. After all, we can get the expectation of repaired cost of the bridge pier. This research will also use New Taipei City bridge risk ranking which analyzed by risk assessment system of disasters. And added it in seventeen bridges which estimated by expectation model of the bridge pier. We can provide results to the government.口試委員會審定書 誌謝 ii 中文摘要 iii ABSTRACT iv 目次 v 圖目錄 vii 表目錄 viii 第一章 緒論 1 第一節 研究動機 1 第二節 研究目的 1 第三節 研究範圍與限制 2 第四節 研究方法與流程 3 第二章 文獻回顧 5 第一節 橋梁受地震災害調查 5 一、 921地震之橋梁震害調查 5 二、 921地震破壞模式統計 8 第二節 橋梁破壞類型與影響 10 一、 常見橋梁受震災害 10 第三節 橋梁維修工法 12 一、 橋梁常見維修工法 12 第四節 橋梁易損性曲線 14 一、 易損性曲線之繪製 14 第五節 橋梁損壞風險 15 一、 災害風險定義 15 二、 橋梁風險推估模型 17 第六節 小結 22 第三章 橋墩補強費用期望值模型建立 23 第一節 橋墩補強費用期望值模型概述 26 第二節 橋梁面板總面積k 26 第三節 橋梁各階段破壞機率P 28 一、 橋梁損壞分級 28 二、 橋墩補強工法建議 30 第四節 單位面積橋墩補強費用Y 34 第五節 小結 38 第四章 新北市省道橋梁補強經費期望值計算 39 第一節 案例橋梁基本資料 39 第二節 符合條件之案例橋梁排序 41 第三節 案例橋梁橋梁面板總面積(k) 42 第四節 橋梁各階段破壞機率P 44 第五節 單位面積橋墩補強費用Y 48 一、 問卷設計 48 二、 問卷結果與分析 50 第六節 橋梁墩部補強費用期望值 53 第七節 小結 60 第五章 結論與建議 61 第一節 結論 61 第二節 建議與後續研究 61 參考文獻 63 附錄 6

    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

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    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.
