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
Origine et impact pronostique de l'hétérogénéité intra-leucémique dans les leucémies aiguës myéloïdes
No full textLes leucémies aiguës myéloïdes (LAM) sont des cancers issus de la transformation d'une cellule souche ou progéniteur hématopoïétique (CSPH) secondaire à l'accumulation d'altérations génétiques et épigénétiques. Comme de nombreux cancers, il existe dans les LAM une diversité intra-leucémique importante, qui peut être génétique, épigénétique et fonctionnelle. Cette hétérogénéité peut représenter un réservoir de résistance au traitement, qui rend dans certains cas la rechute inévitable. La diversité génétique est l'aspect de l'hétérogénéité intra-tumorale la plus étudiée en oncologie. Dans les LAM, le nombre de clones (richesse) et leur répartition (équitabilité) ont été rapportés associés au risque de rechute dans les LAM traitées par chimiothérapie intensive. Par ailleurs, certaines architectures clonales spécifiques ont également une valeur pronostique. Ainsi, dans les LAM avec réarrangements du core-binding factor (CBF), l'évolution parallèle de mutations dans les gènes des voies de signalisation (récepteurs à activité tyrosine kinase et effecteurs d'aval) est associée à un risque plus élevé de rechutes après traitement par chimiothérapie intensive. En utilisant les LAM avec mutation de NPM1 et réarrangements CBF comme maladies modèles, nous avons caractérisé les intéractions entre l'hétérogénéité génétique et fonctionnelle sur des prélèvements primaires de patients. Puis, en utilisant des approches de génomique et des expérimentations cellulaires sur cellules primaires de patients, et un modèle murin syngénique de LAM CBF, nous avons cherché à élucider les mécanismes biologiques sous-jacents à l'émergence d'une évolution parallèle des mutations de signalisation. En particulier, nous souhaitons démontrer le lien entre le caractère souche des LAM et la présence d'une architecture clonale branchée. Enfin, en utilisant deux larges cohortes de patients avec des LAM CBF annotées sur les plans génétique et fonctionnel, nous avons cherché à identifier les relations pronostiques causales entre le caractère souche, l'évolution parallèle et le risque de rechute après traitement par chimiothérapie intensive.Acute myeloid leukemias (AMLs) are cancers resulting from the neoplastic transformation of a hematopoietic stem or progenitor cell (HSPC) secondary to genetic or epigenetic alterations accumulation. Like many cancers, AMLs have significant intra-leukemic diversity, which may be genetic, epigenetic and functional. This heterogeneity may represent a reservoir of drug resistance, which in some cases makes relapse inevitable. Genetic diversity is the most studied aspect of intra-tumor heterogeneity in oncology. In AMLs, the number of clones (richness) and their relative size distribution (evenness) have been reported associated with relapse risk in AMLs treated with intensive chemotherapy. In addition, specific clonal architectures also have prognostic impact. For example, in AML with core-binding factor (CBF) rearrangements, parallel evolution of mutations in signaling pathway genes (tyrosine kinase receptors and downstream effectors) is associated with a higher risk of relapse after intensive chemotherapy treatment. Using AML with NPM1 mutations and CBF rearrangements as model diseases, we characterized the interactions between genetic and functional heterogeneities on primary patient samples. Then, using genomic approaches and cell-based experiments on primary patient cells, and a syngeneic mouse model of CBF AML, we sought to elucidate the biological mechanisms underlying the emergence of parallel evolution in these diseases. In particular, we wanted to demonstrate the link between the stemness of the leukemia and the presence of a branching clonal architecture. Finally, using two large cohorts of patients with genetically and functionally annotated CBF AMLs, we sought to identify the causal prognostic relationships between stemness, parallel evolution and relapse risk after intensive chemotherapy treatment
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.
