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
Teaching with GIS in 2006 High School Geography Curriculum Standard.
No full textGeographic Information System（GIS）提供強大功能用以儲存、復原、繪圖與分析空間相關地理資料，本研究旨在探討95/99課綱實施後，台灣高中地理科教師如何評價GIS這個教學利器來協助學生們建構學科知識。了軟體的操作複雜度與高昂價格、教學時間限制及教師技術的熟練度/信心外，這些使用/不使用的教師是否認為它是適合且有益於啟發地理思維？ 研究者以質性研究的半結構式訪談法，以方便取樣及滾雪球取樣方式深度訪談北部地區十位樣本教師與三位專家—包含教育部自九十一年起的高中GIS系列計畫種子教師，同時進行為期近一年的兩種向度觀察法；整理博多稿並以理論編碼後得到如下結論：.GIS融入教學適合實踐在人文社會資優班及選修課。.Google Earth推出新版後能避開使用GIS的障礙因素並具備部分功能（如地形剖面、地圖套疊、語音導覽），廣受歡迎與友善介面/生活化特質成為良好替代方案。.某些學校會透過其他管道申請經費購買ArcView9.X軟體或更新設備。.初階基礎環境可採用IGIS（WEBGIS）方式。.即使教師們清楚GIS的魅力與有力功能，但是課綱中每個主題概念的理解重要性優先於部分技能的養成。.教師們將種子計畫所設計的模組視為優質的輔助物。Geographical Information System（GIS）provide tremendous utilities for storage, retrieval, mapping and analysis of spatially referenced geographic data. This research intends to delineate how high school geography teachers in Taiwan view this collaborative and productive tool to enhance students’ content knowledge after the new curriculum standard advent. xcept the manipulative sophistication and prohibitive price of software, pedagogy time limitation and the instructor’s technological proficiency/faith, do those who（don’t） teach by GIS perceive it as appropriate and relevant to motivate geography thinking？he author interviewed ten samples qualitatively in the north areas and three experts, including seeds of Ministry of Education（MOE） masterplans since 2002. By convenience/snowball sampling with abstract criteria combines observation in two domains, then theoretical coded the protocols from transcripts. Here are the sentiment sequence—.Both” Humanity --Social talented class” and “Optional class” are proper occasions to facilitate “teaching with GIS”..Google Earth avoids the insurmountable barriers of true GIS so becomes a prior subsidiary while it is popular..Some schools apply for other financial allowance to purchase ArcView9.X or update the equipment..IGIS（WEBGIS） offers introductory /ultimate level environment..Teachers are conscious of the engaging and instrumental function from GIS, but geographical concepts are the most important issue compare to requisite skill learning.. Faculty consider modules of MOE masterplans as the refined supplement.圖目錄 III目錄 IV一章 緒論 1一節 研究動機 1二節 研究目的 2三節 研究限制 3二章 文獻回顧 4一節 主要國家之地理教育 4二節 台灣高中地理課程改革 6三節 地理科95暫綱與98課程綱要 10四節 地理資訊的角色 13五節 高中地理教師地理資訊能力 24六節 科技與學習 34三章 研究方法 43一節 研究對象 43二節 半結構式訪談法 49三節 研究流程 51四節 訪談大綱 52四章 研究成果 54一節 訪談檔案紀錄 54二節 樣本分析 58三節 主題編碼 61四節 理論編碼 64五章 結論與建議 82一節 結論 82二節 建議 85考文獻 86錄一 林口高中國土資訊系統操作分組操作單 93錄二 「95年度高中職地理科資訊融入課程研發與推廣計畫」模組範例網頁摘錄 95錄三 GIS相關資源 96錄四 訪談大綱 97錄五 北一女中95學年度第二學期高一人文社會資優班GIS研習 98錄六 97年宜蘭高中社區化課程「野外調查與地理資訊技術應用」 9
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
