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
Sonar image recognition system to clear mines
No full textDet finns ett intresse för att skapa säkra farvägar för militär och civil båttrafik. I svenska vatten ligger det kvar många havsminor från världskrigen som behöver röjas för att kunna skapa dessa vägar. Om en mina ska kunna röjas på ett säkert sätt är det till fördel att ha information om vilken bottentopografi som den befinner sig i. Detta görs genom att samla in sonarbilder ifrån autonoma undervattensfarkoster, AUV:er. I denna rapport undersöks sonarbilderna genom att analysera en bit i taget med hjälp av olika kvadratiska filterstorlekar som roteras. Den bildbit som filtret täcker analyseras med hjälp applicering av en Gaussianfunktion som med hjälp av diskret Fourier Transform tar fram fyra olika varianser. Haar- funktionen har ej använts då den inte har samma noggrannhet i rumsdimensionen som Gaussian-funktionen har. Dessa varianser beskriver hur bildbiten varierar i en punkt, en linje, i radie samt i vinkel. Olika kombinationer av dessa varianser leder till olika inneboende dimensioner i bildbitens mittersta pixel. De inneboende dimensionerna beskriver bottentopografierna på olika sätt. Med hjälp av deep learning appliceras metoderna på ett träningsset som består av ett antal sonarbilder som plockats ut för vardera dimension. Med hjälp av Fourier-metoden beskriven ovan bestäms gränserna med ett konfidensintervall på 95%. De gränser som fanns längst ifrån 0 samt 1 var 0.22257 respektive 0.77708. Gränserna applicerades i algoritmen som sedan tog fram numeriska värden för de inneboende dimensionerna. Utifrån dessa resultat blev det möjligt att presentera säkra farvägar genom grönmarkerade områden i sonarbilden. De filter som genererade det noggrannaste resultatet var de minsta filtren för alla rotationer.There is an interest to make safe routes for military and civil boat traffic. In the Swedish seas there exist a lot of mines from the world wars that need to be removed to create these highways. If a mine is going to be demined in a safe way it is in favor to have information about what kind of seafloor topography it is laying on. This is done by collecting sonar images from autonomous underwater vehicles, AUV:s. In this report the sonar images are analyzed by investigating a smaller piece of the image. This is done by using different quadratic filter sizes which are rotating. The image piece which the filter is covering is analyzed by applying a Gaussian function that in combination with a discrete Fourier transform is producing four different variances. The Haar-function is not used since it has a lower accuracy in the dimension of the room than the Gaussian function has. These variances describes how the image piece varies in a point, a line, radius and angle. Different combinations of those variances are resulting in different intrinsic dimensions in the middle pixel of the image piece. The different intrinsic dimensions describes the seafloor topography in different ways. The methods are applied on a training set with deep learning. The training set consists of sonar images which are chosen for every dimension. Applying the above mentioned Fourier-method it is possible to choose the boundaries with a confidence interval of 95%. Those boundaries that were most far away from 0 and 1 were 0.22257 respectively 0.77708. These limits are applied in the algorithm that later on determines the numerical values for the intrinsic dimensions. It was possible to present safe highways in green in the sonar image from these results. Those filters that generated the highest accuracy were the smallest filters for all rotations

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.
