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

Die Rolle des parodontalen Status und der subgingivalen bakteriellen Belastung bei therapierefraktärer rheumatoider Arthritis
No full textEINLEITUNG: Obwohl sich die therapeutischen Möglichkeiten ständig erweitern, erreicht bis zu einem Drittel der PatientInnen mit rheumatoider Arthritis (RA) nicht das Behandlungsziel einer Krankheitsremission, oder niedrigen Krankheitsaktivität. Man spricht hier von Therapie- refraktärer RA (re-RA). Es wird vermutet, dass Stressoren an mukosalen Oberflächen (z.B.: Lunge, Mundhöhle oder Gastrointestinal Trakt) wichtige Auslöser der re-RA darstellen. Mehrere Studien deuten darauf hin, dass Parodontitis einer dieser Stressoren sein könnte.
ZIEL: Das Ziel dieser Studie war es zu untersuchen, ob re-RA PatienInnen einen schlechteren parodontalen Status und eine höhere Belastung durch Parodontitis Erreger aufweisen als RA PatientInnen, welche sehr gut auf die Therapie ansprechen (treatment amenable RA, ta-RA).
METHODEN: Alle Teilnehmer wurden umfassend rheumatologisch und zahnmedizinisch evaluiert. Ebenso wurden alle relevanten demografischen Charakteristika erhoben. Die zahnmedizinische Evaluation beinhaltete einen vollständigen parodontalen Status, sowie eine PCR-Bestimmung der elf wichtigsten Parodontitis Erreger. Aus den parodontalen Messwerten wurden clinical attachment loss (CAL), periodontal epithelial surface area (PESA) und periodontal inflamed surface area (PISA) berechnet.
RESULTATE: Neunundfünfzig Personen erfüllten die Einschlusskriterien. Vierunddreißig gehörten zur re-RA und 25 zur ta-RA Gruppe. In der re-RA Gruppe gab es signifikant mehr mehr Frauen (94% re- RA vs. 52% ta-RA) und mehr Nicht-RaucherInnen. Nachdem für diese Unterschiede korrigiert wurde, gab es außer einem Trend zu höherem Zahnverlust unter Personen mit re-RA (p = 0,076) jedoch weder in den parodontalen Messwerten noch in der Anwesenheit oder Häufigkeit parodontaler Erreger statistisch signifikante Unterschiede.
SCHLUSSFOLGERUNG: Diese Querschnittsstudie war die Erste mit einer umfassenden Definition von re-RA im Kontext von Parodontitis. Personen mit re-RA hatten tendenziell mehr Zähne verloren.INTRODUCTION: Despite continuing advances in therapeutic options, a significant proportion of patients with rheumatoid arthritis (RA) remain unresponsive to treatment, which is often termed “refractory RA” (re-RA). The proportion of affected patients is as high as one third. It has been hypothesized that stress at mucosal surfaces (i.e. lungs, oral mucosa and gastrointestinal tract) might be an important driver of re-RA. A growing body of literature suggests periodontal disease (PD) as a likely candidate.
AIM: Therefore, the goal of this study was to determine whether re-RA is associated with worse periodontal status and higher oral microbial burden when compared with RA that is amenable to treatment (ta-RA).
METHODS: An extensive rheumatologic and periodontal evaluation together with demographic characteristics was taken. Periodontal evaluation included a full periodontal status from which, clinical attachment loss (CAL), periodontal epithelial (PESA) and periodontal inflamed surface area (PISA) were calculated. A PCR to 11 periodontal pathogens from crevicular fluid was performed.
RESULTS: Fifty-nine individuals met the inclusion criteria. Of those, 34 were in the re-RA and 25 in the ta-RA group. The groups differed significantly in gender (94% vs. 52% female, in re-RA vs. ta-RA) and smoking status, with less active and previous smokers in re-RA compared to ta-RA. After correcting for these differences, there were no differences in indices of periodontal status between groups, but a trend towards higher tooth-loss (p = 0,076) in the re-RA group. There were no differences in subgingival periodontal pathogens, neither in presence nor abundance.
CONCLUSION: This cross-sectional study was the first to use a sound definition of re-RA in the context of PD. Using this definition, we found a trend towards higher tooth loss in patients with re-RA, when compared with ta-RA patients.Abweichender Titel laut Übersetzung der Verfasserin/des VerfassersDiplomarbeit Medizinische Universität Wien 202
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
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
