    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

    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

    Cadomian Influence on the pre-Sardic series of the Eastern Pyrenees : geochemical, stratigraphic and geochronological approach

    La stratigraphie de l’Ediacarien-Ordovicien Inférieur des Pyrénées Orientales est révisée. Le découpage stratigraphique est similaire aux successions de la Montagne Noire (France) et de la Sardaigne (Italie) tenant compte de (1) l’absence de déformation cadomienne au cours de la transition Ediacarien-Cambrien, (2) la présence, comme dans la Montagne Noire septentrionale, d’un volcanisme acide proche de la limite Ediacarien-Cambrien, et (3) l’absence des corps régressifs du Guzhangien (Cambrien moyen terminal) comme au Sud-Ouest de la Sardaigne. Les analyses géochimiques du volcanisme de l’Ediacarien supérieur des Pyrénées Orientales suggèrent deux affinités distinctes, une tholéitique liée à un contexte d’extension (métabasites des Formations de Nyer et d’Olette) et une autre calco-alcaline et à dominance acide liée à l’orogénèse Cadomienne (sommet de la Formation d’Olette et Formation du Pic de la Clape). Une révision des zircons détritiques des dépôts terreneuviens de la partie nord-occidentale péri-gondwanienne (Maroc, massif Ibérique, Montagne Noire, Pyrénées et Sardaigne) reflète l’influence relative des principales sources de sédiments suivant une polarité SO-NE : les sources panafricaines et atlasiennes prédominent dans les successions les plus sud-occidentales, tandis que l’influence du craton Arabo-Nubien et du méta-craton Saharien augmente vers le NE. Cette tendance disparait ensuite, reflétant une possible homogénéisation géodynamique et des sources continentales le long de cette marge.The Ediacaran-Lower Ordovician stratigraphy of the Eastern Pyrenees is updated and revised. A similar stratigraphic framework is compared with neighbouring outcrops from the Montagne Noire (France) and Sardinia (Italy), which take into account: (i) the absence of Cadomian deformation close to the Ediacaran-Cambrian boundary interval, (ii) the presence, like in the northern Montagne Noire, of acidic-dominated volcanosedimentary complexes punctuating the Ediacaran-Cambrian transition, (iii) the lack of the Guzhangian (mid Cambrian) regression, also absent in SW Sardinia. The geochemical analysis of the uppermost Ediacaran volcanism in the Eastern Pyrenees suggest two distinct affinities linked to extensional conditions (metabasites of the Nyer and Olette formations) followed by the influence the Cadomian orogeny (acidic and calk-alkaline magmatism recorded at the top of the Olette Formation and in the overlying Pic de la Clape Formation). Detrital zircons from Terreneuvian siliciclastic sediments of West Gondwana (Morocco, Iberian Massif, Montagne Noire, Pyrenees and Sardinia) reflect a distinct SW-NE trend in the relative influence of major sediment sources: the Panafrican-Atlasian sources predominate throughout the southwesternmost successions, whereas the influence of the Arabian-Nubian Shield and the Sahara Metacraton sources increases northeastward. This trend tends to disappear afterwards, possibly reflecting a common geodynamic evolution throughout this margin

    Dispelling the Myths Behind First-author Citation Counts

    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

    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.
