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
Study of the genetic factors of susceptibility to rheumatoid arthritis
No full textLa polyarthrite rhumatoïde, le rhumatisme inflammatoire chronique le plus fréquent, est une maladie multifactorielle faisant intervenir des facteurs génétiques et environnementaux. Depuis 1978, l’implication du gène HLA-DRB1 est connue, puis en 2005 celle du gène PTPN22, impliqués dans plusieurs autres maladies auto-immunes. Ces deux gènes n’expliquent qu’une partie de la composante génétique de la PR. Ces deux dernières années ont connu une augmentation considérable du nombre des gènes associés à la PR grâce aux études pangénomiques mais les résultats des études publiées sont souvent controversés. Les objectifs de ma thèse sont donc 1) l’étude, par une approche familiale dans la population française en particulier et européenne en général, des nouvelles hypothèses d’association de nouveaux gènes émanant de ces études pangénomiques; 2) la recherche d’autres facteurs génétiques de prédisposition à la PR à l’aide d’une stratégie fondée sur le reséquençage systématique de régions d’intérêts et de gènes candidats. Mon travail de thèse a ciblé, dans un premier temps, les facteurs génétiques fortement suggérés : STAT4, TRAF1/C5, 6q23/TNFAIP3, REL et BLK. D’autres loci ont été aussi étudiés dans le cadre d’une grande étude européenne cas-témoins, tels que : AFF3, KIF5A, CD40, IL2/IL21, CTLA4, CD226, CCL21, CD226, PRKCQ, IL2RA et IL2RB. Parallèlement, l’étude de 20 gènes candidats ainsi que du locus PADI a été entreprise par reséquençage. Ces travaux ont permis d’apporter la confirmation définitive par linkage de la région 6q23/TNFAIP3 comme nouveau facteur génétique de la PR. Un premier argument de liaison a été obtenu pour le gène STAT4, ainsi qu’une suggestion de liaison pour les gènes REL et BLK. Par ailleurs, une réplication de l’association avec le gène AFF3 a été obtenue par la grande étude cas-contrôle européenne. Enfin, le reséquençage a permis de découvrir de nouveaux variants alléliques, qui sont utilisés pour rechercher de nouveaux facteurs de la PR. En conclusion, mon travail a contribué à l’identification de facteurs génétiques de la PR, qui conduira à une meilleure compréhension des mécanismes moléculaires impliqués dans la pathogenèse de cette maladie, jusqu’à permettre le développement de nouvelles thérapeutiques visant à guérir définitivement la PR.Rheumatoid arthritis (RA), the most frequent inflammatory chronic joint disease, is a multifactorial disease, caused by genetic and environmental etiological factors. Since 1978, the involvement in RA susceptibility of the gene HLA-DRB1 is known, as well as that of the PTPN22 gene in 2005, also implicated in several other autoimmune diseases. These two genes explain only part of RA genetic component. During the last two years, thanks to genome wide association studies, (GWAS) the number of genes associated with RA has increased dramatically, but the results of published studies are often controversial. The objectives of my thesis were 1) to investigate, using a family-based approach, the hypotheses of new genes from GWAS studies, in the French population in particular and the European population in general, and 2) to search for new genetic factors predisposing to RA using a strategy based on systematic re-sequencing of candidate gene’s regions of interest. My thesis work has been focused, initially, on the genetic factors strongly suggested: STAT4, TRAF1/C5, 6q23/TNFAIP3, REL and BLK. Other loci were also investigated as part of a large European cases-controls study, such as AFF3, KIF5A, CD40, IL2/IL21, CTLA4, CD226, CCL21, CD226, PRKCQ, IL2RA and IL2RB. At the same time, the re-sequencing study of 20 candidate genes, as well as the PADI locus has been undertaken. This work brought the definitive confirmation through the linkage proof of the 6q23/TNFAIP3 region as a new RA factor. A first linkage evidence was obtained for the STAT4 genes, and a linkage suggestion for the REL and BLK genes. Besides, a replication of the RA association with the AFF3 gene was obtained by the large European cases-controls study. Re-sequencing of candidate genes led to the identification of new alleles to be investigated in the search for new RA factors. In conclusion, my work contributed to the identification of RA genetic factors, which will enable a better understanding of the molecular mechanisms involved in the pathogenesis of this disease, leading to the development of new therapeutic targets for a definitive treatment of RA
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

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.
