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
Astrophysique transitoire et multimessager avec les télescopes à imagerie Tcherenkov atmosphérique
No full textI hunt very-high-energy (VHE) emission from three classes of transient sources: Gravitational waves (GW), their possible gamma-ray bursts (GRB) counterparts and fast radio bursts (FRB). I tackle three types of challenges: Preobservation, focusing on efficient scheduling, observation planning and fast telescope response; in-observation, focusing on efficient data acquisition on the transients as an expert on call; post-observation, focusing on efficient data analysis in the search for a significant signal. For the GW events, the poor localization requires a special treatment for the follow-up. I work on the optimization of GW follow-up strategies that rely on the maximization of the probability of detecting counterparts to transient GW events either by using solely GW localization maps or by correlating the local distribution of the galaxies in the Universe with GW maps. The tools are combined in a GW scheduler, tested and assessed. Using the developed tools and acquired skills, I develop automatic response schemes to GW alerts for the H.E.S.S. and LST telescopes and a response to UTMOST FRB alerts for H.E.S.S. I also contribute to the update of the GRB program in H.E.S.S. on the technical follow-up front. With the implemented tools, H.E.S.S observed 6 GW events, of which 4 BBH mergers. Other transient sources, for which I am involved in the analysis, are observed also by H.E.S.S.: GRB 190829A, GW170817 (long-term), FRB events and the soft gamma-ray repeater (SGR) SGR 1935+2145. GRB 190829A is the third GRB to be observed at VHE energies on the ground and the second one by H.E.S.S. The VHE data (in addition to the Xray and UV data for FRB 20171019A) is analysed for the other transients. No significant VHE emission was found during the BBH merger follow-up and the GW170817 long-term follow-up observation campaigns. The same non-detection was found for the FRBs and SGR 1935+2154. For those, a search for variability on the minutes to sub-seconds scale did not lead to any significant detection either. Upper limits are derived from the observations of the transients presented above. These results are published and the upper limits permit to constrain the magnetic field in the GW170817 remnant, to constrain the persistent and transient emission from SGR bursts and to derive prospects for the fourth GW observation run, O4.Je recherche des émissions de très hautes énergies (VHE) à partir de trois types de sources transitoires : les ondes gravitationnelles, les sursauts gamma qui peuvent en émerger et les sursauts radio rapides. Pour les ondes gravitationnelles, la localisation des évènements sur plusieurs dizaines de degrés dans le ciel nécessite un traitement spécial pour le suivi. J'optimise des stratégies de suivi ondes gravitationnelles qui reposent sur la maximisation de la probabilité de détection d'émission électromagnétique homologue, soit en utilisant uniquement des cartes de localisation, soit en utilisant aussi la distribution locale des galaxies dans l'Univers. Les outils développés sont testés et évalués. À l'aide de ces outils et des compétences acquises, je développe un système de réponse automatique aux alertes ondes gravitationnelles pour les télescopes H.E.S.S. et LST et aux alertes UTMOST pour H.E.S.S. Je contribue à la mise à jour du programme de H.E.S.S. de suivi de sursaut gamma. Avec les outils mis en place, H.E.S.S a observé 6 événements ondes gravitationnelles, dont 4 fusions de trous noires. D'autres sources transitoires sont également observées par H.E.S.S., dont le sursaut gamma GRB 190829A, la fusion d'étoile à neutron GW170817 (à long terme aussi), des sursauts radio rapides et la source SGR 1935+2145. GRB 190829A est le troisième sursaut gamma détecté à très hautes énergies au sol. Les données VHE, sont analysées (ainsi que les données X et UV pour FRB 20171019A) pour les autres sources. Aucune émission significative de VHE n'a été trouvée durant les suivis des fusions de trous noirs et durant la campagne d'observation à long terme de GW170817, ainsi que pour les sursauts radio rapide et la source SGR 1935+2154. Je déduis des limites supérieures et publie ces résultats. Les limites déduites permettent de contraindre le champ magnétique dans le vestige de GW170817, de placer des limites supérieures sur l'émission VHE persistante et transitoire provenant des sursauteurs gamma mou, et d'établir des perspectives pour O4
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

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.
