    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    Full text link
    We 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

    Full text link
    We 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

    Compressibility of municipal solid waste and its implications

    No full text
    This paper deals with the compressibility of municipal solid waste (MSW) with the purpose of highlighting the engineering implications related to the waste subsidence during disposal, closure and quiescence. A parametric analysis of settlement is carried out for a 40 m high MSW column, by considering two biological degradation models, EPA and SWANA, known in the technical literature. The biodegradation models are implemented inside a one-dimensional numerical model of waste column, increasing in height with a prefixed law. The model takes into account the mass loss resulting from the biodegradation process and the fluid transport along the vertical direction, from the most saturated areas towards the less saturated. The effect of pore pressure, resulting from both the production of biogas or from the raising of the leachate level, is neglected in the hypothesis that the plant remains efficient in time. It is assumed that the leachate is continuously recirculated from the top to the base of the waste column. The analyses have the purpose of investigating the magnitude of the three components of settlement, immediate, creep and biodegradation, at the end of the disposal phase, after the construction of the coverage barrier and, finally, after thirty years from the closure. Bio-mechanical parameters are in part adapted from the technical literature [GOURC et al., 2010] and in part obtained from large diameter oedometric tests carried out at the ICEA Department of the University of Padua [COSSU et al., 2015]. In the light of engineering applications, the main results achieved are: - The two biodegradation models, EPA and SWANA, do not have a decisive influence on the waste settlements for disposal rates in the range of the usual practice; however, as showed by the data of Tab. VII, the choice of the model may be helpful in order to calculate the mean degree of maturation of biodegradable matter. - The filling coefficient, that is the ratio between the reached MSW height and the planned one, is strongly dependent on the disposal rate. The engineering goal is of assessing the optimal disposal rate to maximize the landfill volume with the lower operating costs. - The differential settlements due to creep and biodegradation can induce failure in the covering barrier. Such settlements are accentuated by a fast disposal rate; a slower rate minimizes this hazard because part of the settlement occurs during the disposal itself. For slower disposal rate, the creep settlement can become more crucial than the biological one. - A careful assessment of the creep parameter is recommended, also in the light of the European policies on MSW, according to which the organic component must be minimized and stabilized by pre-Treatment. - The immediate settlement of MSW and the relative law of evolution represent a very critical point for the subsidence problems occurring during disposal and closing; in this respect, it should be taken into greater consideration the extra-situ pretreatments and those in-situ (compaction, preloading), in order to stabilize the medium. As a final practical indication, it is suggested to run numerical simulations of the landfilling program in order to ascertain the final landfill profile and the coverage stability; on the basis of such analyses it will be possible to redefine the cultivation plan to minimize the costs of management and postclosure. Concluding, it is clear how geotechnics can bring a basic contribution in the design of MSW landfills; anyway, the need of a multidisciplinary approach is also evident, in order to avoid drawbacks in a complex field not yet fully consolidated

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We 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 text
    In 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.
