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
Formative Key-Feature-Prüfungen als innovativer Lehransatz im Studium der Zahnmedizin: Ein Projektbericht
No full textIntroduction: Clinical reasoning ability is one of the core competencies of physicians. It should already be trained during undergraduate medical education. At University Medical Center Göttingen (UMG), medical students can participate in formative key feature examinations in which they work on virtual patient cases in order to apply and deepen the procedural knowledge acquired in lectures and seminars.Problem and objective: While this teaching format is already established in the medica l curriculum at the UMG, it has not yet been implemented in the dental curriculum at the same institution. Therefore, the current project aimed to evaluate the feasibility of formative key feature examinations in dental education.Methods: In 2022, new key feature cases focusing on dental-surgical teaching content were created. For pilot testing, the new cases were worked on by two cohorts of dental students via an online learning platform in February 2023. The students were also asked to complete an anonymous online questionnaire in order to evaluate the new teaching format.Results: Overall, the formative key feature examinations were evaluated positively by the dental students, and they demanded for further dental key feature cases. However, descriptive analyses of item characteristics as well as students' comments in the questionnaire revealed some potential for improvements, so that a few cases were partly revised afterwards.Conclusion and outlook: This project shows that formative key feature examinations are feasible in dental education and that dental students can benefit from working on virtual case scenarios. Whether dental students' clinical reasoning competence can be improved by completing formative key feature examinations is being investigated in an ongoing study at the UMG.Einleitung: Klinische Entscheidungskompetenz gehört zu den Kernkompetenzen von Mediziner*innen. Sie sollte bereits während des Studiums trainiert werden. An der Universitätsmedizin Göttingen (UMG) können Studierende der Humanmedizin bereits seit 2013 an formativen Key-Feature-Prüfungen teilnehmen, um das in Vorlesungen und Seminaren erworbene prozedurale Wissen in virtuellen klinischen Fällen anzuwenden und zu vertiefen.Problem- und Zielstellung: Während das Lehrformat im Humanmedizinstudium an der UMG bereits etabliert ist, wurde es im Studium der Zahnmedizin am gleichen Standort bislang nicht implementiert. Das hier vorgestellte Projekt zielte deshalb darauf ab, die Realisierbarkeit formativer Key-Feature-Prüfungen in der Zahnmedizin zu evaluieren.Methoden: Im Sommer und Herbst 2022 wurden zahnmedizinisch-chirurgische Key-Feature-Fälle erstellt. Zur Pilotierung wurden die virtuellen Fälle zwei Kohorten von Zahnmedizinstudierenden über eine Online-Lernplattform zur Verfügung gestellt. Die Studierenden wurden außerdem gebeten, einen anonymen Online-Evaluationsfragebogen zu dem neuen Lehrformat auszufüllen.Ergebnisse: Die Evaluationsergebnisse zeigten, dass die formativen Key-Feature-Prüfungen von den Zahnmedizinstudierenden positiv bewertet wurden und dass die Studierenden sich weitere Fälle wünschten. Durch deskriptive Analysen der Fallbearbeitungen und die studentische Evaluation wurde jedoch auch Verbesserungspotential in den erstellten Key-Feature-Fällen sichtbar, so dass die Fälle im Nachgang teilweise überarbeitet wurden.Schlussfolgerung und Ausblick: Das vorliegende Projekt zeigt, dass formative Key-Feature-Prüfungen auch im Studium der Zahnmedizin umsetzbar sind und dass Studierende von der Bearbeitung der virtuellen Fälle profitieren können. Inwieweit sich die Bearbeitung von Key-Feature-Fällen objektiv messbar auf den Lernerfolg der Studierenden auswirkt, wird zurzeit in einer laufenden Studie untersucht
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
