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
Complications thromboemboliques veineuses chez les patients hospitalisés pour COVID-19
No full textMédecine vasculaireIntroduction : l’infection au SARS-CoV-2 a été associée à un risque thrombotique élevé partiellement expliqué par la réaction inflammatoire systémique, des durées d’hospitalisation longues, la présence de cathéters centraux et d’ECMO. Un potentiel thrombotique intrinsèque du virus est questionné devant la mise en évidence d’un anticoagulant circulant (ACC) chez certains patients infectés. Objectifs : cette étude s’est proposé d’évaluer l’incidence des évènements thromboemboliques veineux (ETEV) chez des adultes hospitalisés pour COVID-19. Méthodes : il s’agit d’une analyse rétrospective des patients consécutivement hospitalisés pour infection au SARSCoV-2 (RT-PCR positive) admis au CHU de Strasbourg du 25/02/2020 au 01/04/2020. Les patients hospitalisés pour moins de 24h ont été exclus. La période d’observation s'étendait jusqu'à la fin de l'hospitalisation. Résultats : au cours de la période d’étude, 943 patients COVID-19 ont été hospitalisés dans notre institution. Parmi eux, 772 ont été inclus dans l’analyse actuelle. L’âge médian était de 68 (56-79) ans et 58 patients avaient un antécédent de maladie thromboembolique veineuse (MTEV). Au total, un ETEV est survenu chez 61 patients (7.9%): 46 embolies pulmonaires (EP), 13 thromboses veineuses profondes isolées et 2 thromboses veineuses superficielles. Sur l’effectif global, 81% des patients avaient bénéficié d’un traitement anticoagulant dès leur admission. L’incidence de la MVTE était supérieure chez les patients avec des formes plus sévère de pneumopathie définie par un des critères suivants: conduisant au décès/nécessitant une intubation ou une oxygénothérapie nasale à haut débit ou une ventilation non-invasive (22% versus 2%, p-0.001). La mortalité totale était de 22.4% et elle était plus élevée chez des patients ayant présenté un ETEV (34% versus 21%, p=0.024). Une recherche d’ACC a été réalisée chez 70% des patients ayant présenté un ETEV et elle s’est avérée positive dans 88% des cas. Au total, 37 complications hémorragiques majeures ont été notées (4.8%) dont 38% cérébrales. En analyse multivariée, la survenue d’un ETEV était corrélée à un âge inférieur à 75 ans, une élévation des D-dimères à plus de 1500ug/l et une atteinte parenchymateuse supérieure à 25%. Conclusion : notre étude a montré que la survenue d’un ETEV était corrélée à la sévérité de pneumopathie COVID-19 et était associée à un risqué plus élevé de décès.ntroduction: SARS-CoV-2 infection was associated with a high thrombotic risk partially explained by systemic inflammatory reaction, long hospital stays, presence of central catheters and ECMO. An intrinsic thrombotic potential of the virus is questioned when a circulating anticoagulant (ACC) is identified in some infected patients. Objectives: This study proposed to assess the incidence of venous thromboembolic events (ETEVs) in adults hospitalized for COVID-19. Methods: This is a retrospective analysis of patients subsequently hospitalized for SARSCoV-2 infection (RT-PCR positive) admitted to the Strasbourg University Hospital from 25/02/2020 to 01/04/2020. Patients hospitalized for less than 24 hours were excluded. The observation period extended until the end of the hospitalization. Results: During the study period, 943 COVID-19 patients were hospitalized in our institution. Of these, 772 were included in the current analysis. The median age was 68 (56-79 years) and 58 patients had a history of venous thromboembolic disease (VTS). A total of 61 patients (7.9%), an ETE occurred: 46 pulmonary embolisms (EPs), 13 isolated deep vein thrombosis and 2 superficial venous thrombosis. Of the total workforce, 81% of patients had received anticoagulant treatment upon admission. The incidence of MVTE was higher in patients with more severe forms of lung disease defined by one of the following criteria: leading to death/requiring high-flow nasal intubation or oxygen therapy or non-invasive ventilation (22% versus 2%, p-001). Total mortality was 22.4% and was higher in patients with ETEV (34% vs. 21%, p-0.024). VAC research was conducted in 70% of patients with ETEV and was positive in 88% of cases. A total of 37 major haemorrhagic complications were noted (4.8%) 38% of whom are cerebral. In multivariate analysis, the occurrence of an ETEV was correlated at an age of less than 75 years, an elevation of D-dimers to more than 1500ug/l and parenchymatous impairment greater than 25%. Conclusion: Our study showed that the occurrence of an ETEV was correlated with the severity of COVID-19 lung disease and was associated with a higher risk of deat

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.
