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
Mécanobiologie de la maladie d'Alzheimer : approches de dépistage à haut contenu pour caractériser les mécanismes de mécanotransduction synaptique et les rôles des facteurs de risque génétique d'Alzheimer
No full textA growing body of evidence suggests that mechanical signaling takes part in synapse formation and plasticity. Considering that a number of genetic risk factors of the late-onsetAlzheimer’s disease (AD) are involved in cell adhesion and that synapse loss is one of the earliest events in AD pathophysiology, it is hypothesized that identifying mechanotransduction signaling downstream of synaptic adhesion molecules (CAMs) will help understand how genetic risk factors contribute to AD and define novel therapeuticapproaches. The overall aim of this project is to discover the mechanobiological mechanisms of synapse formation and loss in physiological and AD conditions through developing high-content screening approaches. First, intracellular signaling pathways downstream of mechanical stimulation of select synaptic CAMs will be determined through developing ahigh-throughput compound screen based on magnetic tweezers force spectroscopy in model cell lines that stably express relevant fluorescent biosensors. Then, a medium-throughput screening based on microfluidic co-culture devices that mimic synapse loss in AD will be developed to determine if the mediators of CAM mechanotransduction affect amyloid beta (Aβ)- or tau-induced synaptotoxicity and whether these effects depend on AD genetic risk factors. Finally, the formation of pre- and postsynaptic structures on human induced neurons will be demonstrated by mechanically stimulating synaptic CAMs and/or pharmacologically interfering with the identified mechanotransduction pathways and to assess how these processes are modulated during Aβ and tau-induced toxicity. Beyond the methodological novelty, this project will considerably enhance the current thinking of synaptic mechanotransduction mechanisms and their potential roles in AD. On the translational aspect, this project is a major step towards making compartmentalized neuron cultures available for compound screening and eventually for drug discovery applications.Un nombre croissant de preuves suggère que la signalisation mécanique participe à la formation et la plasticité des synapses. Considérant qu'un certain nombre de facteurs derisque génétiques de la maladie d'Alzheimer (MA) forme tardive sont impliqués dans l'adhésion cellulaire et que la perte de synapse est l'un des premiers événements de laphysiopathologie de la MA, il est supposé que l'identification des voies de signalisation de mécanotransduction en aval des molécules d'adhésion cellulaire (MAC) synaptiques aidera comprendre comment les facteurs de risque génétiques contribuent à la MA et définir de nouvelles approches thérapeutiques. L'objectif global de ce projet est de découvrir les mécanismes mécanobiologiques de la formation et de la perte des synapses dans les conditions physiologiques et de la MA en développant des approches de dépistage à hautcontenu. D’abord, les voies de signalisation intracellulaires en aval de la stimulation mécanique de certaines MAC synaptique seront déterminées en développant un dépistage àhaut débit basé sur la spectroscopie de force à micro-pinces magnétiques dans des lignées cellulaires modèles qui expriment de manière stable des biocapteurs fluorescents pertinents. Ensuite, un criblage à débit moyen basé sur des dispositifs de co-culture microfluidiques qui imitent la perte de synapse dans la MA sera développé pour déterminer si les médiateurs de la mécanotransduction MAC affectent la synaptotoxicité induite par la bêta-amyloïde (Aβ) ou tau et si ces effets dépendent des facteurs de risque génétiques de la MA. Enfin, la formation de structures pré- et post-synaptiques sur les neurones induits humaine sera démontrée en stimulant mécaniquement les MAC synaptiques et/ou en interférant pharmacologiquement avec les voies de mécanotransduction identifiées et pour évaluer comment ces processus sont modulés pendant la toxicité induite par Aβ et tau. Au-delà de la nouveauté méthodologique, ce projet améliorera considérablement la réflexion actuelle sur les mécanismes de mécanotransduction synaptique et leurs rôles potentiels dans la MA. Sur le plan de l’application, ce projet est une étape majeure vers la mise à disposition de cultures de neurones compartimentées pour le criblage de composants et éventuellement pour des applications de découverte de médicaments
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.
