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
Process Status Evaluating Tool: How can the pump process be evaluated pumping water?
No full textDamen Dredging Equipment (DDE) has a quest to make their cutter suction dredger (CSD) and their DOP pump operable by everyone for every slurry type at the correct working point every time. To complete this quest, first a process status evaluating tool has to be developed which replaces the visual wear inspection. This thesis is the first step in developing this tool, its research question hence is "How can the pump process status be evaluated pumping water?" To answer this question, first a literature study about a centrifugal pumpis done (chapter 1) to understand the working principle of a centrifugal dredge pump. Next, the wear locations in a centrifugal dredge pump are going to be examined (chapter 3) after a small wear definition introduction (chapter 2). From the wear locations found, the ones that are expected to have the most influence on the pump performance (head H and efficiency ´) are further researched in this thesis. These locations are: the axial gap and the inner impeller diameter. For the axial gap, data was already available due to previous research at DDE [1]. The data for the influence of the inner impeller diameter change is created by own experiments on the sediment transport circuit at DDE, these experiments are explained in chapter 5. Also another conditionmonitoring option (not only the influence of the pump parameters) is researched after different possibilities were investigated (chapter 4). This method is the vibration analysis of the pump and is used to see whether or not the influence of wear on the pump can bemonitored. This wear is created by pumping a slurry (sand-water) mixture through the sediment transport circuit while using casted steel for the impeller and wear plate (it would take a lot of time to create wear on the original nihard impeller and wear plate). The data for the axial gap, inner impeller diameter and vibrational analysis is explained in chapter 6. The research question can be answered in two parts: the influence on the pump parameters and the vibration analysis of the pump. The data analysis of the influence of the axial gap on the pump parameters (section 6.1) shows that it is possible to indicate whether the axial gap is small or large (2mm vs 11mm) by using a trialand- error method proposed in this study. The data analysis of the inner impeller diameter (section 6.2) shows two methods to calculate the inner diameter increase from the data obtained during the own experiments. Both methods are based on the change of the velocity triangles resulting in an extended version of the pump affinity law for head. The NPSH could not be measured decent, so no model is obtained for this. The last part to answer the research question is the vibrational analysis (in radial, axial and tangential direction). The BEP point can be found using the vibrational analysis (lower vibration level). Also cavitation in the pump is detected by the vibrational analysis (high scattering of vibrational data points). A last thing that can be seen is when the pump operates left from the BEP, the axial vibration level increases a lot. All the findings in chapter 6 should be tested for not only the DOP250, but for a various range of pumps and settings. This to conclude if the findings are applicable for every pump, or only for the DOP250 in setting used in the sediment transport circuit.Mechanical, Maritime and Materials EngineeringOffshore & dredging engineerin
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.
