Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
3D WMn MPRAGE increased detection of spinal cord lesion in multiple sclerosis
No full textIntroduction : comparaison d’une séquence 3D WMn par rapport aux séquences conventionnelles 2D T2 FSE, 2D STIR, 2D PSIR et 3D T1-MPRAGE à 3T, afin de détecter des lésions de la moelle épinière dans la sclérose en plaques. Matériels et méthodes : il s’agit d’une étude prospective monocentrique qui a été approuvée par un comité d'examen institutionnel. Les patients ont été recrutés d'octobre 2021 à juillet 2022. La séquence 3D WMn et les séquences conventionnelles ont été examinées de manière aléatoire et indépendante par deux neuroradiologues. Pour toutes les lésions trouvées par les deux lecteurs, une session de lecture consensuelle a été réalisée par deux neuroradiologues seniors. Le critère d'évaluation principal était le nombre de lésions de la moelle épinière cervicale dans la SEP. Les critères d'évaluation secondaires comprenaient le nombre de lésions de la moelle épinière thoracique dans la SEP, le niveau précis des lésions, la confiance dans les lésions indiquées par les lecteurs, la concordance inter et intra-observateur, la présence d'artéfacts et la corrélation entre le nombre total de lésions et le score EDSS. Un test de Wilcoxon a été utilisé pour comparer les deux ensembles de données. Résultats 30 participants ont été inclus. La séquence 3D WMn a détecté significativement plus de lésions que l’ensemble des séquences conventionnelles (141 contre 83 respectivement, p<0.001). 23 participants avaient au moins une lésion sur la séquence 3D WMn qui n'était pas détectée sur les séquences conventionnelles. La confiance dans les lésions indiquées par les lecteurs était significativement plus élevée avec la séquence 3D WMn qu'avec les séquences conventionnelles. Les reproductibilités inter- et intra-observateurs étaient plus élevés avec la séquence 3D WMn. La séquence 3D WMn était sujette à très peu d'artefacts. Il n'y avait pas de corrélation avec le score EDSS. Conclusion : l'analyse a montré que la séquence 3D WMn améliorait la détection des lésions de la moelle épinière chez les patients atteints de SEP, avec une plus grande confiance dans leurs existences, une meilleure concordance inter et intra-lecteur, très peu d'artefacts, par rapport aux séquences conventionnelles.Abstract: background and purpose to compare 3D WMn with conventional dataset including 2D T2w, 2D STIR, 2D PSIR and 3D T1-MPRAGE at 3 Tesla in the detection of spinal cord injury in multiple sclerosis. Material and methods: this prospective single-center study was approved by an institutional review board and enrolled participants from October 2021 to July 2022. The two data sets were randomly and independently examined by 2 neuroradiologists. For all lesions found by the two readers, a consensus reading session was performed by two senior neuroradiologists. The primary endpoint was the number of cervical spinal cord lesions in MS. Secondary endpoint criteria included the number of thoracic spinal cord lesions in MS, precise level of lesions, rater-reported confidence in the lesions, inter- and intra-agreement, the presence of artifacts and the correlation between the number of total lesions with the EDSS score. A Wilcoxon’s test was used to compare the two datasets. Results: 30 participants were included. 3D WMn detected significantly more lesions than the conventional dataset (141 versus 83 respectively, p<0.001). 23 participants had at least one lesion on 3D WMn which was not detected on the conventional dataset. Rater-reported confidence were significantly higher with 3D WMn than with the conventional dataset. Inter- and intra-observer agreements were higher with 3D WMn. There were few artifacts on the 3D WMn. There was no correlation with the EDSS score. Conclusion: 3D WMn improved MS spinal cord lesion detection as compared to conventional dataset, with better confidence, and better inter and intra agreement with few artefacts
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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.
