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
Teacher collaboration as community of practice – the impact of collective-implicit knowledge on cooperation-based competence development
Full text linkDie Erwartungshaltung gegenüber positiven Wirkungen von Lehrerkooperation ist hoch, allerdings sind die empirischen Belege für ihre Wirkungsmächtigkeit im Hinblick auf Lehrerkompetenz und Schülerleistung kaum belastbar. Der vorliegende Beitrag thematisiert den Zusammenhang von Handlungskompetenz und Lehrerkooperation unter dem Einbezug von kollektiv-impliziten Wissensbeständen, die vor allem im deutschsprachigen Raum bisher vernachlässigt wurden. Auf Basis der theoretischen Kontrastierung des Konzepts der Professionellen Lerngemeinschaften und der Community of Practice werden die Grenzen des ersten und die Bedeutung des letzteren Ansatzes für Lehrerkooperationsforschung und -praxis aufgezeigt. Der damit verbundene rekonstruktive forschungsmethodische Zugang wird angewendet, um community-spezifische Orientierungen von Lehrkräften als Teil von Handlungskompetenzen herauszuarbeiten. Der community-spezifische Umgang mit Problemen zeigt, wie bedeutsam kollektiv-implizite Wissensbestände für die Handlungskompetenz von Lehrkräften sind. (DIPF/Orig.)Expectations on positive effects of teacher collaboration on teachers’ competence and pupils’ performance are huge, although empirical evidence is hardly reliable. This contribution thematizes the relation of action competence and teacher collaboration by focusing on social-implicit knowledge, which is neglected especially in German research. Based on a theoretical contrast of the concepts of professional learning community and community of practice we illustrate the limitations of the former and the importance of the latter for research on teacher collaboration. The related reconstructive methodological approach is used for reconstruction of community-based orientations as part of teachers’ action competence. The community-dependent way of dealing with problems shows the importance of collective-implicit knowledge for action competence. (DIPF/Orig.
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
Forschungsperspektiven und -befunde zum Forschenden Lernen im Praxissemester: Plädoyer für eine Zielklärung
Full text linkDie mit dem Forschenden Lernen verbundenen Verständnisse werden in der Literatur als vielfältig bewertet und die damit einhergehenden Auswirkungen als problematisch für Erforschung, hochschuldidaktische Umsetzung sowie Wirkungsannahmen gesehen (Huber & Reinmann, 2019). Vornehmlich in der Lehrkräftebildung entwickelte sich ein eigener Diskurs. Im vorliegenden Aufsatz wird dafür plädiert, die immer wieder benannte spezifische, berufsperspektivische Zielsetzung des Forschenden Lernens in der Lehrkräftebildung stärker theoretisch auszuformulieren, um die Verständnisklärung von Forschendem Lernen vor diesem Hintergrund vorantreiben zu können. Damit einhergehend werden aktuelle Forschungsbefunde und -erkenntnisse des Forschenden Lernens im Praxissemester in Deutschland berichtet und diskutiert. Es werden mögliche Ansatzpunkte für die theoretische Weiterentwicklung und damit verbundene Implikationen für die Praxis aufgezeigt
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
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
