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
Impact de la pandémie COVID-I9 chez les femmes enceintes et atlaitantes suisses - une étude cross sectional de la première vague de la pandémie
No full textLes informations sur l'impact de la pandémie de COVID-19 sur les expériences de grossesse et d'allaitement, ainsi que sur la santé mentale périnatale en Suisse sont limitées. En Suisse, il existe peu d'études et d'informations nationales. En utilisant une enquête anonyme en ligne accessible après la première vague de l'épidémie en Suisse, nous avons étudié l'impact de cette pandémie sur les femmes enceintes et allaitantes. Parmi les femmes ayant répondu à l'enquête, 69,0% (1050/1518) ont indiqué que la première vague de la pandémie avait eu un impact sur leurs habitudes personnelles, 61,0% (689/1131) ont été affectées dans leur travail et 40,0% (632/1573) ont rapporté des relations altérées avec les services de santé (les différents dénominateurs correspondent au nombre de participantes ayant répondu à la question). 36,8% (110/299) des femmes ont signalé un impact de la pandémie sur leur expérience actuelle de la grossesse ou de l'allaitement (8,2%, 46/555). Dans l'ensemble, 11,6
% (170/1467) des participantes ayant rempli les tests de dépistage validés de symptômes de santé mentale (Edinburgh Postnatal Depression Scale, Generalized Anxiety Disorder 7, Perceived Stress Scale) ont présenté un score compatible avec des symptômes de dépression majeure, d'anxiété grave ou de stress perçu élevé, ce qui est plus important par rapport à la période pré-pandémique selon la littérature. Les facteurs de risque indépendamment associés à une santé mentale altérée sont le fait d'être hospitalisé pour un COVID-19, de présenter des symptômes de COVID-19, de vivre avec une personne ayant des symptômes de COVID-19, d'avoir des comorbidités, d'avoir fait l'expérience de services de santé réduits, d'avoir des activités habituelles restreintes et d'être une femme au foyer. Les facteurs de protection indépendamment associés sont un niveau d'éducation élevé et le fait de vivre avec un partenaire. Nos résultats suggèrent que les femmes enceintes et allaitantes pourraient avoir été significativement affectées dans leur bien-être et leur santé mentale par la pandémie de COVID-19, directement en cas d'exposition, et indirectement en raison des modifications potentielles dans leurs habitudes de vie et dans leur relation avec les services de santé
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
Patisiran exposure in early pregnancy: a case report.
Full text linkWe describe here the first case of exposure to patisiran treatment, a small interfering RNA molecule, during early pregnancy of a 36-year-old woman with symptomatic hereditary transthyretin-related amyloidosis. There were no major complications during pregnancy and delivery, except for a postpartum hemorrhage due to uterine atony. Vitamin A levels had to be closely monitored during pregnancy, and vitamin A substitution adapted accordingly. There was no sign of minor or major congenital abnormalities of the baby. One month after delivery, the patient showed slight clinical and electrophysiological signs of neuropathy progression due to patisiran treatment withdrawal. Patisiran infusions were resumed 3 months after delivery. Due to the unknown teratogenic potential of patisiran, the risk of neuropathy worsening associated with withholding treatment must of course be weighed against a potential teratogenic risk of treatment during pregnancy. Vitamin A levels need to be closely assessed, and substitution must be adapted accordingly, to avoid embryofetal adverse outcome due to vitamin A deficiency or toxicity
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
