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
Optimization of therapeutic strategies in interventional radiology : application in embolization and oncology
No full textLa radiologie interventionnelle (RI) présente des avantages indéniables. Grâce aux techniques d’embolisation, les patients présentant des hémorragies pouvant engager le pronostic vital, peuvent être traités. Les agents liquides collants peuvent être utilisés or, leur technique d’utilisation reste très empirique. Les complications des embolisations à la colle peuvent être gravissimes. Leur maniabilité peut être appréhendée. Dans la 1ère partie de ce travail nous avons étudié in vitro les caractéristiques de plusieurs colles et notamment les dernières mises sur le marché (Glubran 2 et Purefill, par rapport à l’Histoacryl), en fonction de leur préparation (température, ratio du mélange avec le lipiodol). Nous avons également étudié les temps caractéristiques de ces 3 colles. La 2ème partie de ce travail a porté sur la RI appliquée à l’oncologie. Elle est scindée en plusieurs travaux ayant comme objectif commun l’optimisation des techniques de RI en hépato-biliaire. Une étude clinique a porté sur l’intérêt et la sécurité des biopsies endobiliaires. Une étude a consisté en la réalisation d’une enquête de pratiques en chimio-embolisation artérielle (TACE) du carcinome hépato-cellulaire en France. Deux études ont porté sur la recherche in vitro du ou des meilleurs agents cytotoxiques sur des lignées cellulaires (mélanomes de l’uvée murines µ2 et µ2F et humaines mel 270 et OMM 1.3 et de cancer colo-rectal HT29, SW 48, SW 480, SW 620, HCT116, CaCo2) en condition de temps d’exposition court (30 minutes) pour imiter les conditions de TACE. L’objectif final était de pouvoir trouver le ou les agents cytotoxiques les plus efficaces pour optimiser les traitements par TACE des métastases hépatiques de ces 2 origines. Pour les mélanomes de l’uvée, il est apparu que le paclitaxel était significativement le meilleur agent parmi ceux testés. Pour les cellules de CRC, l’idarubicine était le meilleur agent cytotoxique, suivi par la gemcitabine Un dernier travail a été réalisé pour appréhender in vitro la partie embolisation de la TACE. L’embolisation a été assimilée à une hypoxie. Nous avons ainsi pu évaluer l’effet de l’hypoxie à 2 niveaux (1 % et 0.2 %) sur la viabilité cellulaire, après que celles-ci aient été mises en contact (30 minutes) avec de la chimiothérapie. Une hypoxie sévère entraine une chimiorésistance dans ces conditions d’évaluation. Ces travaux doivent amener à des études sur modèle animal ainsi qu’à la mise en place d’essais cliniques.Interventional radiology (IR) has undeniable advantages. With embolization techniques, patients with potentially life-threatening haemorrhage can be treated. Glue can be used but, their technique of use remains very empirical. The complications of glue embolization can be very serious. Their maneuverability can be apprehended. In the first part of this work we studied in vitro the characteristics of several glues and in particular the latest releases on the market (Glubran 2 and Purefill, compared to Histoacryl), according to their preparation (temperature, mixing ratio with lipiodol). We also studied the characteristic times of these 3 glues. The second part of this work focused on the RI applied to oncology. It is divided into several works with the common objective of optimizing the RI techniques in hepatobiliary. A clinical study focused on the interest and safety of endobiliary biopsies. A study consisted in the realization of a survey of practices in arterial chemo-embolization (TACE) of hepatocellular carcinoma in France. Two studies focused on in vitro research of the best cytotoxic agent (s) on cell lines (uveal melanoma murine u2 and μ2F and human mel 270 and OMM 1.3 and colorectal cancer HT29, SW 48, SW 480, SW 620, HCT116, CaCo2) under short exposure time (30 min) to mimic TACE conditions. For uveal melanomas, it was found that paclitaxel was significantly the best agent among those tested. For CRC cells, idarubicin was the best cytotoxic agent, followed by gemcitabine. The ultimate goal was to find the most effective cytotoxic agent (s) to optimize the TACE treatment of liver metastases from these 2 origins. A final work was done to apprehend in vitro the embolization part of the TACE. Embolization has been equated with hypoxia. We were able to evaluate the effect of 2-level hypoxia (1% and 0.2%) on cell viability after they were exposed (30 minutes) with chemotherapy. Severe hypoxia leads to chemoresistance under these conditions of evaluation. This work should lead to studies on animal models as well as the establishment of clinical trials

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.
