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

Vascular Stromal Fraction for the treatment of the radiation induced gastro intestinal syndrome
No full textL'exposition aux rayonnements ionisants suite à un accident d'irradiation ou un acte de malveillance peut concerner à la fois des personnes civiles et militaires. Cette exposition peut engendrer des conséquences graves sur la santé des personnes exposées et impacter potentiellement un grand nombre de personnes. Chez l'homme, les doses supérieures à 6 Gy sur un large volume induisent principalement une destruction de la moelle osseuse et des lésions gastrointestinales, entraînant diarrhée, déshydratation, septicémie et hémorragie intestinale avec une mortalité dans les 10 à 15 jours suivant l'exposition. Ce syndrome létal induit la perte de cellules souches intestinales (CSI) et entrave ainsi la régénération épithéliale. L'épithélium intestinal ainsi endommagé entraîne une rupture de la barrière favorisant l'influx systémique d'agents pathogènes bactériens. Ces symptômes gastro-intestinaux sont collectivement connus sous le nom de syndrome gastro-intestinal radio-induit (SGI). Engageant rapidement le pronostic vital, le SGI est encore aujourd'hui face à un mur thérapeutique et sa prise en charge n'est que symptomatique. De plus, les délais d'intervention pour le traitement des personnes irradiées est primordiale et il existe un besoin énorme de mesures thérapeutiques efficaces et rapides. Le traitement par des produits dérivés du tissu adipeux et plus particulièrement la fraction stromale-vasculaire (SVF) est compatible avec des traitements d'urgence (pouvant être préparée à proximité du bloc opératoire et sans culture cellulaire). Les retombées potentielles de cette étude seront importantes pour la prise en charge médicale et rapide des personnes irradiées présentant un SGI. L'objectif de cette thèse est d'identifier les cibles cellulaires du traitement par la SVF dans un environnement intestinal déficitaire en cellules souches intestinales induit par l'irradiation et d'évaluer le rôle et l'importance des cellules myélo-monocytaires de l'hôte dans les interactions stroma-cellules souches intestinales pour la régénération intestinale chez la souris. La première étape est axée sur l'évaluation des cellules intestinales cibles du traitement du SGI par la SVF. La deuxième étude consistera à évaluer le rôle des monocytes/macrophages dans le SGI et leur participation dans les effets thérapeutiques induit par la SVF. Cette étude a permis de montrer un effet direct de la SVF sur le compartiment cellule souche et que la coopération entre le monocyte de la SVF et le monocyte de l'hôte est nécessaire pour assurer l'efficacité de la SVF pour le SGI.Exposure to ionizing radiation following an irradiation accident or a terrorism act can affect both civilians and military personnel. This exposure can have serious consequences on the health of exposed persons and potentially impact a large number of people. In humans, doses higher than 6 Gy over a large volume mainly induce bone marrow destruction and gastrointestinal lesions, leading to diarrhea, dehydration, septicemia and intestinal hemorrhage with mortality within 10 to 15 days after exposure. This lethal syndrome induces the loss of intestinal stem cells (ISC) and thus, impairs epithelial regeneration. The damaged intestinal epithelium results in a breakdown of the barrier, allowing systemic influx of bacterial pathogens. These gastrointestinal symptoms are collectively known as radiation-induced gastrointestinal syndrome (GIS). Although life-threatening, GIS is still facing a therapeutic wall and its management is only symptomatic. Moreover, the time of intervention for the treatment of irradiated persons is primordial and there is a huge need for effective and rapid therapeutic measures. Treatment with products derived from adipose tissue and more particularly the stromal-vascular fraction (SVF) is compatible with emergency treatment (can be prepared close to the operating room and without cell culture). The potential impact of this study will be important for the medical and rapid management of irradiated persons with a GIS. The objective of this thesis is to identify cellular targets of SVF treatment in an irradiation-induced intestinal stem cell deficient environment. The second objective is to evaluate the role and importance of host monocytes cells and the interaction between the host immunity and the stroma-intestinal stem cell for intestinal regeneration in mice. The first step is focused on the evaluation of intestinal cells targeted by SVF treatment of IGS. The second step will evaluate the role of monocytes/macrophages in GIS and their involvement in the therapeutic effects induced by SVF. This study demonstrated a direct effect of SVF on the stem cell compartment and that the cooperation between the SVF monocyte and the host monocyte is necessary for SVF to be effective in GIS
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.
