Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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 linkWe 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 linkWe 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
Broadening the gene pool of cultivated peanut (Arachis hypogaea) : application for population development, QTLs mapping and breeding
No full textL'arachide (Arachis hypogaea L.) est une plante allotétraploïde (2n = 4x = 40) issue d'un événement récent d'hybridation entre deux espèces sauvages suivi d'un doublement spontané des chromosomes. La variabilité génétique existant dans le compartiment cultivé est faible. Les espèces diploïdes sauvages apparentées à l'arachide cultivée représentent un important réservoir d'allèles nouveaux utilisables pour élargir le pool génique du cultigène. L'objectif général de cette thèse est d'augmenter les marges de progression en amélioration de l'arachide par recours aux ressources génétiques sauvages. Nous avons développé une population BC1F1 à partir du croisement entre Fleur11 et un amphidiploïde synthétique (A. ipaensis x A. duranensis)x4 qui associe les génomes des plus probables progéniteurs sauvages de l'espèce cultivée. Nous avons d'abord construit une carte génétique comprenant 298 loci positionnés sur 21 groupes de liaison avec une taille totale de 1843.7 cM. Nous avons ensuite conduit une analyse AB-QTL pour plusieurs caractères impliqués dans la productivité, l'adaptation et la domestication de l'arachide. Au total, nous avons cartographié 95 QTL. Pour plusieurs QTL, les effets positifs sont associés aux allèles provenant des espèces sauvages. Nous avons aussi identifié trois régions du génome qui portent des empreintes de la domestication. Nous avons enfin développé une population de 122 lignées d'introgression à l'aide d'une stratégie de sélection assistée par marqueurs. L'ensemble des groupes de liaison sont couverts avec des frag ments chevauchants, issus des donneurs sauvages, d'une taille moyenne de 39.2 cM et chaque lignée comprend en moyenne 1.2 fragments. Nous avons par ailleurs discuté l'utilisation de cette collection de lignées d'introgression pour des applications de sélection et de recherche. Nos résultats ouvrent de nouvelles perspectives pour l'amélioration de l'arachide par croisement avec les espèces sauvages apparentées.Peanut (Arachis hypogaea L.) is considered to be an allotetraploid (2n = 4x = 40) originated from a single hybridization event between two wild diploids followed by spontaneous chromosomes duplication. Cultivated peanut harbours a limited genetic diversity. Peanut wild relatives represent an important source of novel alleles that could be used to broaden the gene pool of the cultigen. The general objective of this work is to enhance the rate of progress in peanut breeding using wild species resources.We developed a BC1F1 population from the cross between Fleur11 and a synthetic amphidiploid (A. ipaensis x A. duranensis)x4 that combines the genomes of the most probable wild progenitors of the cultigen. We first developed a SSR based genetic map of 298 loci on 21 linkage groups, spanning a total map distance of 1843.7 cM. We then conducted a detailed AB-QTL analysis for several traits involved in peanut productivity and adaptation as well as in the domestication syndrome. We mapped a total of 95 QTLs. About half of the QTL positive effects were associated with alleles of the wild parents and several QTLs involved in yield components were specific to the water-limited treatment. We identified three genomic regions which bear footprints of domestication. We finally developed, through a marker assisted backcross strategy, an exotic introgression library of 122 lines. This population, which has in average 1.2 fragments per line, allows covering all linkage groups with overlappi ng wild donor fragments of in average 39.2 cM length. The utilization of the exotic introgression lines library for breeding and research is discussed. Our findings open new avenues for peanut improvement using wild relatives

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.
