    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

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    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

    Integrating administrative data-bases, passive surveillance and GIS.

    Integration of data from different sources could provide an effective support in the epidemiological analysis of animal diseases, even in small-scale areas. Our need to integrate GIS (the Veterinary Service of the Province of Reggio Emilia has georeferred, among the ohers, all the bovine, swine, ovi-caprine and poultry farms) and the other administrative data-bases (the National Data Bank and our local data bank ) to gather, manipulate and analyze data from different sources found solution in the use of the ‘R’ software (www.r-project.org - 1). ‘R’ is a highly flexible, expandible and customizable statistical open-source software and an environment which provides all the necessary tools for data analysis and manipulation. R has also the capability of accessing data from a PostgreSQL server (where data are daily exported from the administrative data banks), via the ‘RODBC’ library, and provides tools for reading, writing and manipulating shapefiles (via the ‘maptools’ library) and advanced and modern instruments for the analysis of geographical data (i.e. the packages: ‘splancs’, ‘spdep’, ‘spatial’, ‘spatstat’, ‘Dcluster’). A real-life example of a successful application of this integrated approach is represented by the analysis of echinococcosis passive surveillance data. During the 5-year period 2001-2005, 229 cases of bovine echinococcosis (from 180 farms of the province of Reggio Emilia, Emilia-Romagna Region, Northern Italy), were found at slaughtering through meat inspection, and reported to the Veterinary Service of the Local Health Unit of Reggio Emilia. In order to estimate the prevalence of echinococcosis at the moment of slaughtering, all the data about cattle from the province slaughtered in the above-mentioned period (218,726 records from 2781 farms) were retrieved from the national data bank (the system which tracks all movements of the Italian bovine population). Since all the reports of the disease concerned cows over 2 years of age and became from only two big slaughterhouses in Lombardy region, the dataset and all the subsequent analyses were restricted only to the cows slaughtered in these two slaughterhouses (48,390 cows from 2003 farms), considering them as a random sample (about 46%) of all the cows over 2 years of age sent to the slaughterehouse from farms in the province. Results and discussion. The prevalence of echinococcosis in cows at slaughtering was 4.7 (95% c.i.: 4.15-5.4) cases / 1000 animals. Both empirical Bayes estimates and kernel smoothing techniques were used to investigate the pattern of spatial distribution of the cases. The analysis revealed a heterogeneity in the prevalence estimates by municipality wich was not attributable to the effect of chance alone. In particular, a cluster of cases was identified in the north-western area of the province corresponding to 6 municipalities, where the highest prevalence reached 13.9 cases / 1000 cows. It is worth noting that, in the same area and in the same period, uncontrolled and illegal grazing of infected ovine flocks caused an outbreak of Brucella melitensis infection in cattle, sheep and goats. These findings could suggest that uncontrolled flock grazing could have represented a risk factor for echinococcosis in the cattle coming from the area considered, especially due to the possible presence of infected dogs or the abandoned carcasses and viscera of sheep (2). The results presented here demonstrate how the goal of gathering and coherently assembling data from different sources (passive surveillance, geographical information system and administrative data-bases, such as the National Data Bank) can be succesfully achieved through (and from within) the open-source environment ‘R’, that provided not only the necessary statistical tools but also a common interface to GIS and databases

    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.
