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
Evaluation of different strategies to prevent drug incompatibilities during continuous infusion
No full textLa perfusion intraveineuse occupe une large place dans les services de soins cliniques. Les patients reçoivent de nombreux médicaments simultanément dans la même voie centrale, où des problèmes de compatibilité entre les médicaments peuvent survenir. La maitrise de ces incompatibilités médicamenteuses, génératrices de particules, représente donc un enjeu majeur dans la prise en charge des patients polymédiqués.La première partie de ce travail est une analyse de la littérature portant sur les incompatibilités médicamenteuses et leurs principales conséquences sur le plan clinique. A ce titre, un chapitre est dédié à l’ensemble des moyens de prévention de ces problèmes, parmi lesquels l’usage de filtres en ligne de perfusion ou de dispositifs de perfusion multi-lumières.La première partie de nos travaux expérimentaux est consacrée à l’évaluation de la filtration terminale comme stratégie de prévention de l’administration de particules aux patients. Dans ce contexte, nos travaux ont porté sur le noircissement des filtres en ligne observé dans un service de réanimation néonatale. L’objectif était de définir la nature de l’incompatibilité en cause et de s’assurer, dans un second temps, de l’efficacité des filtres malgré les phénomènes de noircissement. Les filtres ont été examinés par microscopie électronique et comptage particulaire. Un aminogramme de la nutrition parentérale a également été réalisé. Une interaction spécifique a été mise en évidence entre un acide aminé (la cystéine) et un oligoélément (le cuivre) dans les poches. De plus, le maintien de la fonction des filtres en ligne a été démontré.La seconde partie de nos travaux est axée sur l’évaluation de l’intérêt d’un dispositif médical multi-lumières innovant dans la prévention des incompatibilités médicamenteuses. Le premier travail mené dans cette thématique a montré in vitro son intérêt à prévenir la survenue d’incompatibilités physiques entre plusieurs associations médicamenteuses, allant de deux à six médicaments administrés simultanément. Nos résultats indiquent que la conception de ces nouveaux dispositifs de perfusion et notamment leur géométrie interne permet de minimiser le temps de contact entre les produits, et ainsi d’améliorer la compatibilité entre les produits, au même titre que le type de solution d’hydratation. Le second travail consistait à poursuivre l’évaluation de ces dispositifs de perfusion multi-lumières en reproduisant un protocole de perfusion utilisé habituellement en hématologie pédiatrique et associant plusieurs médicaments incompatibles à l’origine de précipité. Un comptage particulaire réalisé de manière dynamique a permis de montrer que l’emploi de ces dispositifs permettait de réduire significativement la charge particulaire administrée aux patients, en comparaison avec les dispositifs standard de perfusion (rampes de robinets).Les résultats de l’ensemble de nos travaux sont prometteurs pour l’amélioration de la prise en charge des patients. Ils doivent être maintenant confirmés au travers d’une étude clinique.Intravenous infusions are extensively used in clinical wards. Patients simultaneously receive many drugs through a limited number of venous accesses, thus increasing the risk of physical drug incompatibilities. Preventing incompatibility is therefore important for the safe administration of injectable drugs of polymedicated patients.The first part of this work consisted in analysing published literature on drug incompatibilities and their clinical consequences. This chapter includes a review of tools preventing drug incompatibilities, which include in-line filtration or the use of multi-lumen infusion sets.The first part of our experimental work is dedicated to the evaluation of terminal in-line filtration for preventing the injection of drug particles to patients. In this context, our research has focused on the blackening of in-line filters, which have been observed during the infusion of binary parenteral nutrition (BPN) delivered in a neonatal intensive care unit. The purposes of our study were, first, to examine the elemental content of precipitates isolated from infused BPN bags and so determine the main physicochemical interactions occurring in them and, second, to evaluate the blackening effect of in-line filters on filtration capacity. Filter membranes were examined by scanning electron microscopy and energy dispersion spectroscopy. Amino acid (AA) profiles were obtained from BPN mixtures to determine the concentrations of each AA. A specific interaction was identify between cysteine and copper in our BPN. Despite the gradual blackening of in-line filters during BPN bag infusion, the filter membranes continued to filter solutions efficiently and safely.The second part of our work focused on the assessment of the impact of new multilumen infusion access devices on the occurrence of known drug incompatibility.The first study used a well-documented incompatible combination of two to six drugs and three different carrier fluids. The multilumen infusion access device was able to prevent the occurrence of drug incompatibilities in nearly half of the drug combinations tested. This study confirmed that the characteristics of an infusion device have an impact on drug physical incompatibilities. The main hypothesis is those fluid dynamics differ according to infusion device and accesses, which modify the contact time between drugs and the infusion vehicle.The second in vitro study focused on a pediatric multidrug protocol for patients diagnosed with lymphoblastic leukemia and receiving allogeneic transplantation. A dynamic particle count test was used over 24 hours to evaluate the overall particulate contamination. The use of a multi-lumen infusion set reduces significantly overall particulate contamination compared to the standard infusion set.These results pave the way to performing a randomized controlled clinical trial assessing the multilumen infusion access device

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.
