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
A Cost-Benefit Analysis on Production of Ethanol and Electricity from Forest Thinning Wood in Taiwan
No full text大氣中二氧化碳的濃度快速增加，使全球暖化問題越趨嚴重。此外，隨著石油價格不斷上漲，生物能源成為取代石油的再生能源之一種方法。從文獻得知，森林疏伐不僅有助林地的碳吸存量，亦可供給疏伐木供生產生物能源之用。本研究分別提出利用疏伐木生產酒精和電力兩種方案，並應用成本效益分析以評估此二方案。 本研究發現，疏伐木生產酒精方案較生產電力方案為佳，前者在要求報酬率16%時為淨現值5,575萬元，後者為767萬元。此外，前者之內部報酬率為18.4%，後者為19%。由此可見，疏伐木生產酒精方案經濟上較可行。 另外，本研究以成本效益分析探討政府採用不同補貼措施獎勵以疏伐木生產酒精，其中以低利貸款增加的內部報酬率最高，其為四個補貼方式中為最具效率之措施。The carbon dioxide in atmosphere had increased rapidly in recent decades, it caused serious global warning problems. Furthermore, current oil price is soaring sharply, and bioenergy becomes one of the alternatives to fossil fuel. According to literature reviews, forest thinning not only can increase carbon sequestration of forestland but also provide wood for producing bioenergy. The study proposed two projects to utilize forest thinning wood to produce ethanol and electricity respectively, then applied cost-benefit analysis to evaluate the two projects.he study found that the ethanol project of forest thinning wood had higher return than the electricity project. At 16% required rate of return, the ethanol project had net present value of 55.75 million NT dollars, the electricity project had 7.7 million NT dollars. Furthermore, the ethanol project had 18.4% internal rate of return, the electricity project 19%. The comparison indicated the ethanol project is more feasible economically.esides, this study used cost-benefit analysis to evaluate different subsidy measures for promotion of using forest thinning wood to produce ethanol. It found the form of grants is the most effective measure in terms of the maximum the internal rate of return of the four subsidy regime.謝誌...................................................i文摘要...............................................ii文摘要...............................................iii目錄 .................................................v目錄..................................................vii一章 緒論 ......................................... ..1一節、研究背景 ........................................1二節、研究目的 ........................................2三節、研究流程 ........................................3二章 文獻回顧 ........................................5一節、林業部門的經營策略對疏伐木產量的影響 ............5二節、生物能源之技術經濟評估 ..........................9三章 研究方法 .......................................22一節、研究理論 .......................................22二節、研究架構 .......................................25四章 以疏伐木生產酒精和發電之成本效益分析 ...........31一節、台灣國有人工林疏伐木供給之推估..................33二節、以疏伐木當作焚化廠發電燃料之方案的成本效益分析..40三節、以疏伐木生產酒精的方案之成本效益分析 ...........56四節、酒精方案和發電方案之比較 .......................73五節、補貼措施之探討 .................................76六節、討論 ...........................................80五章 結論與建議 .....................................83考文獻 ...............................................86錄 ...................................................9
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

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.
