Shadowing school principals: what do we learn?
No full textWhile shadowing as a method has been analysed and discussed, these discussions have often been focused on (business) management research as opposed to school leadership research. Additionally, little attention has so far been paid to the parameters of shadowing. Without knowledge of these matters, the validity, merits and difficulties of shadowing and data collected through shadowing are impossible to assess. This contribution aims at tackling these issues. First, it attempts to offer an overview of shadowing. Next, studies on school principals making use of shadowing are analysed, guided by the following research questions: What are the aims of the studies? How is shadowing defined by the author(s)? What are the parameters of the shadowing activities (duration, observers, observed persons)? What are the categories of observation? In conjunction with what other – if any – methods is shadowing used? What – if any – merits or pitfalls of shadowing are discussed?Finally, implications of the current use of shadowing are discussed and suggestions are offered to address desiderata uncovered during the analysis as well as to further develop the method.</jats:p
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
Leadership in German Schools (LineS2020)
No full textDie Relevanz von Schulleitung für die Schulentwicklung sowie für die Leistungen von Schülerinnen und Schülern wird inzwischen international wie national konstatiert. Zwar liegen in Deutschland vereinzelt empirische Studien zum Schulleitungshandeln vor, jedoch fehlen bislang umfassende Befunde zu ihren Karrieren. So sind Fragen dazu, was das Amt der Schulleitung für Lehrpersonen attraktiv macht, warum Schulleitungen diese Position ergreifen und welche Gründe gegen einen Verbleib im Amt sprechen im deutschsprachigen Raum unzureichend erforscht. Dies ist vor dem Hintergrund eines zunehmenden Mangels an qualifizierten Bewerbungen für das Amt und angesichts recht häufiger Schulleitungswechsel von besonderer Brisanz. Das Projekt wirft daher die Frage auf, was das Amt der Schulleitung (un)attraktiv macht und welche Karrieremotive und Arbeitsplatzwechselabsichten Schulleitungen haben. Es nimmt dabei eine Vielzahl individueller und struktureller Bedingungsfaktoren in den Blick. Dabei werden auch die Rolle von Unterstützungsangeboten (z.B. Mentoring) und von Qualifizierungsmaßnahmen (Professionalisierung) berücksichtigt. Darüber hinaus wird untersucht, wie diese Faktoren mit dem doppelten Anspruch an Schulleitungen zusammenhängen, Schulen in der Verwaltung stabil und effizient zu führen sowie gleichermaßen Schulen anpassungsfähig und flexibel durch Schulentwicklung zu gestalten (Perspektive der Ambidextrie). Grundlage der Studie ist ein für Deutschland repräsentativer Datensatz (n = 405) zu Schulleitungen an allgemeinbildenden Schulen, der über den Felddienstleister forsa GmbH im Rahmen einer Online-Befragung erhoben wurde. Das Projekt nutzt ein Messwiederholungsdesign, um die teilnehmenden Schulleitungen im Abstand von mehreren Jahren wiederholt zu befragen. Es handelt sich um ein Kooperationsprojekt zwischen Prof. Dr. Colin Cramer und Dr. Jana Groß Ophoff (Tübingen), PD Dr. Marcus Pietsch (Lüneburg) und Prof. Dr. Pierre Tulowitzki (Windisch, Schweiz)
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
