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
Subjektive und objektive Evaluierung der Implantatversorgung in der ästhetischen Zone
No full textZielsetzung Ziel der Diplomarbeit war es alle gängigen Ästhetik-parameter auf ihre Reproduzierbarkeit zu untersuchen und miteinander zu vergleichen.
Zusätzlich wurde die Korrelation der Patientenzufriedenheit mit den Ergebnissen der Ästhetik-parametern untersucht. Material & Methoden Es wurden 189 Patienten untersucht, die in der ästhetischen Zone implantiert wurden. Vier Beurteiler (darunter ein Zahnmedizinstudent, ein Kieferorthopäde, ein Chirurg und ein Medizinstudent) werteten in zwei Durchgängen mit allen gängigen Ästhetik-indizes (metrische Indizes:
Pink Esthetic Score (PES), Implant Crown Aesthetic Index (ICA), Pink and White Esthetic Score (PES/WES), Complex Esthetic Index (CEI) und Implant Aesthetic Score modified (IASm), ordinal skalierte Indizes:
Papilla-Index, Subjektiv Ästhetik Score modifiziert (SES) und Rompen) anhand rechtwinkelig angefertigten intraoralen Fotos. Die subjektive Patientenzufriedenheit wurde mittels einer VAS-Skala festgehalten. Resultate Alle metrischen Indizes und der PI-Index zeigten eine gute bis sehr gute intraobserver-Korrelation, der SES und Rompen-Index hingegen nur eine mäßige. Außer beim ICA-Index zeigten alle metrischen Indizes eine mäßig bis gute inter-observer Korrelation in beiden Durchgängen. Die ordinalen Indizes hingegen zeigten nur eine schlechte bis mäßige inter-observer Korrelation. Bei den metrischen Indizes unterschieden sich im ersten Durchgang der Zahnmedizinstudent und Kieferorthopäde nicht signifikant voneinander wie auch im zweiten Durchgang der Zahnmedizinstudent und der Medizinstudent. Bei allen metrischen Indizes beurteilten der Medizinstudent deutlich strenger und der Chirurg am unkritischsten. Die statistische Analyse zeigte eine statistisch signifikante Korrelation zwischen der Patientenzufriedenheit (VAS) und der metrischen Ästhetik-Parametern. Die Patientenzufriedenheit zeigte mit den ordinal skalierten Indizes keine statistisch signifikante Korrelation. Beim Vergleich der zementierten mit verschraubten Kronen, zeigten die verschraubten Kronen bei meisten Untersuchern keinen statistisch signifikanten Unterschied. Schlussfolgerung Insgesamt konnte gezeigt werden, dass alle indizes mit Ausnahme des ICA, SES und Rompen- Indizes reprduzierbar sind. Alle metrischen Indizes zeigten einen signifikant positiven Zusammenhang mit der Patientenzufriedenheit, der bei den ordinalen Indizes nicht nachgewiesen werden konnte. Außer ICA, Rompen und SES sind alle Indizes objektiv und könnten auch in tägliche Praxis angewendet werden.Aim The aim of this study was to examine the reproducibility of current esthetic parameters and compare the patient's opinion (VAS) with the esthetic parameters of single-tooth implants in the esthetic zone. Material & Methods 189 patients treated with a single implant in the esthetic zone were enrolled in this study. Four observers (dental student, orthodontist, oral surgeon and medical student) applied all current esthetic parameters (metric indices: PES, ICA, PES / WES, CEI and IASm, ordinal scaled indices: PI, SES and Rompen) twice on 189 implant-supported single tooth restorations. A visual analog scale (VAS) was used to assess patient's satisfaction with the treatment outcome from an esthetic point of view. Results All metric indices and the PI showed very good to excellent intra-observer agreement. SES and Rompen, however, only moderate correlation. Apart from ICA all metric indices showed moderate to good inter-observer agreement in both ratings. Ordinal indices, however, only showed poor to moderate inter-observer correlation. For metric indices in the first rating no significant difference was found between the ratings of the student and orthodontist and in the second rating between the student and the medical student. For all metric indices the medical student was found to have rated poorer ratings than the others. The surgeon however, rated higher than all others. The statistical analysis revealed statistically significant correlation between patient satisfaction (VAS) and metric esthetic parameters. Patient satisfaction showed no statistically significant correlation with ordinal scaled parameters. Overall screw-retained restorations were found to show significant better esthetics than cement-retained restoration.
Conclusion The metric indices are an objective tool in rating the esthetics of implant supported crowns and adjacent soft tissues and could be applied in daily practice. Only the ICA, Rompen and SES indices showed poor agreements. The statistical analysis revealed a statistically significant correlation between VAS and all metric aesthetic parameters.eingereicht von Muhammad-Nabeel UmarAbweichender Titel laut Übersetzung der Verfasserin/des VerfassersZusammenfassung in engl.

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
