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
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

Preparation of High Refractive Index Zirconium Dioxide / Silicone Resin Composite Materials and Its Application on LED Encapsulating Materials
No full text 本研究分為兩個部分，第一部分是利用溶膠凝膠法，直接在LED矽樹脂封裝材料中，合成具有高折射率之二氧化鋯奈米顆粒，使用醋酸當作螯合劑來控制二氧化鋯的顆粒大小和改質二氧化鋯的表面，將二氧化鋯顆粒導入商用LED矽樹脂中，並在合成二氧化鋯之溶膠凝膠過程中，選用適當的溶劑防止二氧化鋯聚集。
將二氧化鋯/矽樹脂複合材料製備成具有高折射率以及高透明度之光學薄膜，並製備下層為高折射率薄膜，上層為A/B劑之折射率漸進式複合膜，藉由折射率的層層遞減，以期後續應用在LED封裝中能達到較高的取光效率；並量測含高折射率二氧化鋯A/B劑之折射率、薄膜之穿透度，以及複合膜之穿透度、吸水性、耐熱性與耐UV光性，以符合LED封裝材料之需求。
第二部分欲探討加入二氧化鋯奈米顆粒對矽樹脂之A/B劑硬化交聯程度的影響，由DSC的反應熱探討二氧化鋯濃度及其顆粒大小，影響矽樹脂之A/B劑聚合之情形。並利用DSC探討含二氧化鋯A/B劑複合膜之聚合情形。The research was divided into two parts. Zirconium dioxide (ZrO2) nanoparticles with high refractive index were introduced into commercial-grade silicone resin by an in-situ sol gel reaction in the first part. The acetic acid was used as chelating agent to control the particle size of ZrO2 and modified the surface of ZrO2 to provide linkages between the water phase of ZrO2 and the oil phase of silicone resins. Moreover, butanol and methyl ethyl ketone were chosen as the co-solvent system to prevent ZrO2 particles from aggregation during the sol-gel process.
Then we synthesized optical films with high refractive index and high transmittance and synthesized composite films with high refractive index thin film on the bottom and encapsulating material on the top of the composite film. Through using the encapsulating materials with decreasing refractive index layer-by-layer, LEDs could achieve higher light extraction efficiency. In order to achieve the requirements of LED encapsulating materials, optical thin films and composite films were synthesized and measured in terms of refractive index, transmittance, water uptake, thermal resistance and UV resistance.
The curing degree of the silicone resin after introducing zirconium dioxide nanoparticles was investigated in the second part. The influences of the concentration and the size domain of the zirconium dioxide on the degree of curing degree was studied by DSC measurement, and the curing degree of the composite film was investigated by DSC measurement as well
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.
