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
The Characterization of High Aspect Ratio Rectangular Jet Flows
No full textSteam assisted gravity drainage (SAGD) is an in-situprocess where an injection well and a production well are used to recover bitumen from oil sands that are past the point of viability for open mining techniques. During operation, sand control technologies are used on the wells to ensure the longevity of the SAGD system. Slotted liners are the most commonly used sand control technology for SAGD due to their low manufacturing costs and their superior mechanical integrity. The design of a slotted liner includes many narrow slots about the circumference. With the placement of the slotted liner on the injection well, the injected steam's flow field is rendered complex. To approach such a complex flow field, a fundamental understanding of the flow exiting a single slot is first necessary.
This thesis aimed to investigate the flow field of a jet exiting a single slot. The aspect ratio, AR, and Reynolds number, Re, of the slot were chosen for study. In order to approach such a task, particle image velocimetry (PIV) techniques were applied to measure the flow field of the emerging jet. Streamwise and cross-sectional measurements were taken using two-dimensional (2D-PIV) and stereoscopic PIV (stereo-PIV) based setups, respectively. The single slot was made to have high-AR configurations of AR =100, 150, 200, and 210 at a constant area of Arec = 12 mm2, which resulted in an equivalent diameter of De= 3.91 mm. The flow rate of the jet exiting the slot was varied so that six Reynolds numbers were observed, at values of Re = 10800, 14400, 18000, 21600, 25200, and 28800. The streamwise measurements were taken within the X-Y plane, at Z = 0, and observed a downstream range spanning from X = 0 to X = 7De. In turn, the cross-sectional measurements were taken downstream from the slot exit, within the Y-Z plane at X = 3De, 5De, and 7De. The first study to be conducted was with regards to high-AR effects. When analyzing the streamwise measurements, many dissimilarities between low-AR and high-AR jets were observed when the velocity decay, streamwise turbulence intensity, and lateral velocity half-width were considered. Further dissimilarities were observed in the cross-sectional measurements when velocities, turbulence intensities, shear stresses, turbulent kinetic energy, and streamwise vorticity were considered. Each jet was found to display a high number of vortex pairs, so it was concluded that AR has a significant influence on the formation of the streamwise vorticity. It was also observed that small-scale disturbances at the slot exit led to large asymmetries in the distribution of vortex pairs, which in turn led to the jets displaying notable asymmetry. From these two observations on the vortex pairs, it was concluded that the initial distribution of the streamwise vorticity led to the overall differences that were perceived between low-AR and high-AR jets. Thus, it was concluded that a significant change in the downstream flow field occurs when high-AR configurations are utilized.
The second study to be conducted was concerned with the influence of Re. Clear Re-based trends were observed to exist when the velocity decay, streamwise turbulence intensity, lateral velocity half-width, and cross-sectional streamwise velocity were considered. Based on the observations, it was observed that fully turbulent flow had not been reached for the first four Re configurations. Few differences were observed between the results of Re = 25200, and 28800, so it was concluded that the critical Reynolds number, Recritical, at which flow are fully turbulent had been passed. Thus, Recritical was observed to occur within the interval of Re = 21600 and 25200. This range was found to be slightly higher than the Recritical range given within the literature. It was further observed that Re directly influences the formation, distribution, and evolution of streamwise vortices. It was found that the number of streamwise vortex pairs and the dissipation of the vortex pairs downstream both increase with increasing Re. An array of evenly spaced vortex pairs was found to exist for fully turbulent jets. Though it was not concluded, it was proposed that the formation of such an array is what allows for fully turbulent jets to behave similarly

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.
