Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
No full textWe 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 evolution of discharges with two and three dimensional trajectories
No full textIn the literature there is limited data available on the behaviour of discharges with three dimensional trajectories, although these are the most commonly found in the flows exiting (ocean) outfalls. The necessary three dimensional trajectory data requires cumbersome experimental systems and specialised laboratory setup. Therefore, results from two dimensional trajectory experiments are commonly extrapolated to enable prediction of the flow trajectories and dilutions of discharges that follow three dimensional paths. Importantly, there are also still some aspects of the behaviour of discharges with two dimensional trajectories that are not entirely clear. Non-buoyant flows discharged at an angle to the ambient flow, oblique discharges, behave either like a strongly advected jet or a momentum puff, depending on the discharge angle. Previous research indicated that the transition angle lies between 20° and 40°. Furthermore there is no clear distinction made between the cross sectional flow structure of buoyant and non-buoyant discharges in a cross flow, advected thermals and momentum puffs, and flow prediction models, like Visjet or Corjet, which assume these flows spread at the same rate.
The primary objectives of this research are to create a more comprehensive dataset for discharges with three dimensional trajectories; to ascertain the transitional discharge angle that separates flows that behave as a strongly-advected jet or a line momentum puff, and to establish whether there is a difference in the cross sectional concentration profiles of buoyant and non-buoyant discharges in a cross flow. The application of a double Gaussian distribution will be carried out for line advected thermals complimenting earlier work with line momentum puffs. The work feeds into these models and therefore can have an indirect impact on outfall design. A light attenuation system is employed to study the various discharges and the dynamic range is extended by developing a multiple dye system. This enables the evolution of the discharges to be measured over much greater distances. The light attenuation system is described in detail to substantiate the experimental results.
The new data shows that the mean tracer distributions for buoyant and non-buoyant discharges in a cross flow are distinct, with the former having a greater peak separation than the latter. This leads to differences in the relationships between peak and centreline concentrations. In addition, while the experimental spreading rates for the two flows are similar, the different forms of the puff and thermal profiles require distinctly different spreading rates for standardised flow profile models, such as the ‘top hat’ models. Differences are also evident in the conversions needed to estimate peak values from the predictions of these standardised profiles and the implications of these differences are discussed in the context of integral models, which are commonly employed to predict the behaviour of such flows. The experimental data from the oblique discharge experiments showed that flows discharged at acute angles up to 32.4° displayed strongly advected jet behaviour, flows discharged at obtuse angles greater than 39.0° displayed momentum puff behaviour, while the intermediate 35.9° discharge appeared as some combination of the aforementioned flows.
A comprehensive experimental investigation into the behaviour of discharges with 3D trajectories has been carried out. The flows were released horizontally at an angle of 90°, 45°, or at 22° to the ambient current and the ambient to initial velocity ratio varied from 0.0042 to 0.057, extending the range of initial conditions previously considered. The experiments show limited variability in trajectory and dilution results around the average values. This provides the basis for conducting future experiments with fewer repetitions. The flows with initial discharges angles of 90° and 45° to the ambient motion, display initially line momentum puff and afterwards advected thermal behaviour. The consistent appearance of the characteristic double peaked distributions alleviates previously published concerns about the ability to transfer the understanding gained from discharges that follow a two dimensional path. However, the different orientations of the two peaks within these flow regimes introduces additional complexity into the transition region. In experiments with an initial discharge angle of 22° the double peak distribution did not develop until the flow evolved into an advected thermal, which was consistent with expectations based on the experiments with oblique discharges

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.
