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
Étude approfondie des galaxies les moins lumineuses avec spectroscopie dédiée, basée sur le relevé Pristine
No full textDwarf galaxies are metal-poor, faint stellar systems orbiting in general around massive host galaxies. They can be used as cosmological probes as well as laboratories to constrain galaxy formation and evolution. However, most of the recently discovered faint satellites have an ambiguous nature. This ambiguity can be lifted with spectroscopy. But using spectroscopy to that end is only effective if enough stars members of these systems can be identified, which is not always the case given their faintness. My thesis presents the detailed studies of three Milky Way satellites, Draco II, Sagittarius II and Laevens 3, that aim to unveil their nature using deep broadband MegaCam photometry and DEIMOS multi-object spectroscopy. These data are supplemented with the new narrow-band, metallicity-sensitive photometry provided by the Pristine survey that complements spectroscopy by identifying the typical metal-poor population of dwarf galaxies. The size of Draco II places the satellite in the realm of dwarf galaxies. If the spectroscopy is not informative in this case, the Pristine survey allows to estimate the metallicity of the system that also suggests a galactic nature. The spectroscopic and Pristine observations of Sagittarius II also marginally hint that it is a dwarf galaxy, although the satellite is slightly more compact than expected for a dwarf at that luminosity. Its orbit suggests that it is in fact a former satellite of the Sagittarius dwarf galaxy that was stripped from its influence by the Milky Way. Finally, the properties of Laevens 3 unambiguously show that it is anouter halo globular cluster.Les galaxies naines sont des systèmes stellaires pauvres en métaux et peu lumineux, orbitant en général autour de galaxies plus massives. Elles peuvent être utiles pour contraindre la cosmologie autant que les processus de formation et d’évolution des galaxies. Cependant, les satellites peu brillants découverts récemment sont de nature ambiguë. Cette ambiguïté peut être levée par des observations spectroscopiques. Utiliser la spectroscopie à cette fin n’est efficace que si suffisamment d’étoiles membres de ces systèmes peuvent être identifiées, ce qui n’est pas toujours le cas pour ces satellites peu brillants. Ma thèse présente les études détaillées de trois satellites de la Voie Lactée, Draco II, Sagittaire II et Laevens 3, visant à lever le voile sur leur nature par l’utilisation de photométrie profonde MegaCam à bande large et de spectroscopie multi-objet DEIMOS. À ces données s’ajoute de la photométrie bande étroite, sensible à la métallicité des étoiles, provenant du relevé Pristine. Celle-ci est complémentaire à la spectroscopie car elle permet d’identifier les populations pauvres en métaux typiques des galaxies naines. La taille de Draco II place le satellite dans le domaine des galaxies naines. Si la spectroscopie n’est pas informative dans ce cas, le relevé Pristine permet d’estimer la métallicité du système, celle-ci suggérant également une nature galactique. Les observations spectroscopiques et Pristine de Sagittaire II laissent également penser qu’il s’agit d’une galaxie naine, même si le satellite est légèrement plus compact qu’attendu pour une naine de cette luminosité. Son orbite, elle, suggère que c’est en fait un ancien satellite de la galaxie naine du Sagittaire, qui a été arraché de son influence par la Voie Lactée. Enfin, les propriétés de Laevens 3 montrent, sans ambiguïté, que le système est un amas globulaire du halo externe

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.
