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
Incidence et caractéristiques de la néphropathie lupique sur l’île de La Réunion (2009-2018)
No full textIntroduction: Lupus nephritis (LN) is a common and severe damage in the course of systemic lupus. The multi-ethnic population and the intensity of the UV radiation raise questions about the frequency and severityof this pathology in Reunion. Our main objective is to determine the average annual incidence of NL in Reunion Island over ten years. The clinical characteristics and the evolution were also studied.Methods: Our observational study included any patient, regardless of age and sex, with NL diagnosed on a native kidney biopsy performed between January 1, 2009 and December 31, 2018. The SLICC criteria also had to be fulfilled. Results: 76 new cases of NL were identified. The standardized incidence of LN in Reunion was 0.97/100,000 inhabitants per year (CI: 0.30-1.64/100,000 inhabitants). In Reunion, 53.9% of LN cases occur in the first year after lupus diagnosis. In the majority of cases, it is initially manifested by an active proliferative form. Compared to membranous LN, proliferative LN is significantly associated with higher complementconsumption and higher anti-native DNA antibody positivity. The average follow-up time of our cohort was 5.8 years. One-third of patients experienced a relapse during follow-up. Overall and renal survival at 5 years were97.4% and 97.2%, respectively. Conclusion: The incidence of NL in Reunion appears to be higher than in Caucasian cohorts without being able to affirm this statistically. It remains significantly lower than that found in the Afro-American population.Introduction : La néphropathie lupique (NL) est une atteinte fréquente et grave au cours du lupus systémique. La population multi-ethnique et l'intensité d'ensoleillement questionnent sur la fréquence et lagravité de cette atteinte à la Réunion. Notre objectif principal est de déterminer l'incidence annuelle moyenne de la NL réunionnaise sur dix ans. Les caractéristiques cliniques et évolutives ont également été étudiées.Méthode : Notre étude observationnelle incluait tout patient quel que soit l'âge et le sexe, atteint de NL diagnostiquée sur une biopsie de rein natif réalisée entre le 1er janvier 2009 et le 31 décembre 2018. Les critères SLICC de 2012 devaient également être remplis.Résultats : 76 cas incidents de NL ont été identifiés. L'incidence de la NL réunionnaise standardisée est de 0,97/100 000 habitants par an (IC : 0,30-1,64 /100 000 habitants). A la Réunion, 53,9% des cas de NL surviennent la première année après le diagnostic de lupus. Dans la majorité des cas, elle se manifeste initialement par une forme proliférative active. En comparaison avec les formes extra-membraneuses, les formes prolifératives sont associées significativement à une plus grande consommation du complément et à une positivité plus importante des anticorps anti-ADN natifs. Un tiers des patients ont présenté une rechute au cours du suivi. Les survies globale et rénale à 5 ans sont respectivement de 97,4% et 97,2%.Conclusion : L'incidence de la NL réunionnaise semble ssemble supérieure à celle dans les cohortes caucasiennes sans pouvoir l'affirmer statistiquement. Elle reste nettement inférieure à celle retrouvée en population afro-américaine
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
