    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

    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

    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

    Guerres de sépultures de saints et luttes pour une sacralisation des territoires au Maghreb

    La guerre autour de la sainte sépulture reflète autant le culte d’un personnage vénéré qu’une lutte dont l’enjeu est le prestige et le pouvoir. Chaque tribu tente par l’intermédiaire de son cheikh de s’imposer et de s’étendre au détriment de ses rivaux en faisant valoir la noblesse ou le caractère prééminent et sacré de son saint favori. La sépulture qui l’abrite est réputée plus vénérable ou plus prestigieuse que celles des tribus ou villages voisins. Le tombeau du saint censé abrité la baraka, garante de puissance et de richesse, devient dès lors l’objet d’une rivalité acerbe entre chefs de tribus. Des filiations nobles, réelles ou fictives, sont mises en avant par chacune des tribus prétendant à l’hégémonie ou à la prééminence sur les autres.The fight over holy sepultures reflects both the cult of a revered figure and a struggle for prestige and power. Through the intermediary of its sheik each tribe tries to impose itself and extend its territory at the expense of its rivals by claiming the nobleness and the pre-eminent and sacred character of its favorite saint. His burial place is said to be more venerable or more prestigious than those of the neighbouring tribes or villages. The saint’s tomb which is supposed to shelter the “baraka”, source of power and wealth, becomes the object of an intense rivalry between the tribes’ chiefs. Real or fictitious noble origins are claimed by each of the tribes who intend to impose its hegemony or pre-eminence over the others.La guerra alrededor del santo sepulcro refleja tanto el culto de un personaje venerado como una lucha cuya apuesta es el prestigio y el poder. Cada tribu trata, por intermedio de su sheik, imponerse y extenderse a costas de sus rivales, haciendo valer la nobleza o el carácter preeminente y sagrado de su favorito. La sepultura que lo abriga es considerada más venerable o más prestigiosa que las de las tribus o los pueblos vecinos. La tumba del santo, que contiene supuestamente la baraka, garantía de poder y de riqueza, se convierte entonces en el objeto de una rivalidad enconada entre jefes de tribus. Filiaciones nobles, reales o ficticias, son destacadas por cada una de las tribus, que pretenden la hegemonía o la preeminencia sobre las otras
