Wie viel Wissenschaft braucht die Lehrerfortbildung - Arbeitsbündnisse im analogen und virtuellen Raum. Online-QLB-Tagung an der Universität Regensburg 2021
No full textDie dritte Tagung in der Reihe "Wie viel Wissenschaft braucht die Lehrerfortbildung" setzte einen Schwerpunkt auf die Frage, wie Arbeitsbündnisse zwischen Partnerinnen und Partnern an Hochschulen, Landesinstituten oder Fortbildungsinstitutionen einerseits und Lehrkräften an den Schulen andererseits gestaltet und ins Werk gesetzt werden können. Die virtuell ausgerichtete Veranstaltung wird in gemeinsamer Verantwortung der Universität Regensburg (Prof. Dr. K. Rincke), der Pädagogischen Hochschule Freiburg (Prof. Dr. L. Holzäpfel) sowie der Universität Kassel (Prof. Dr. F. Lipowsky) gestaltet. Viele Autorinnen und Autoren haben ihre Beiträge für den Tagungsband ausgearbeitet. Die 31 Beiträge repräsentieren die Arbeiten, die im Rahmen von Gruppenvorträgen, Einzelvorträgen, Workshops und Postern präsentiert wurden. (DIPF/Orig./Herausgeber

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
What Drives Corporate Tax Rates Down? A Reassessment of Globalization, Tax Competition, and Dynamic Adjustment to Shocks
No full textWe reassess the driving forces behind the recent decline of corporate tax rates in Europe. Using data for up to 32 countries from 1983 to 2006, we analyze the role of economic and financial openness as well as tax competition while allowing for dynamic adjustment to shocks and period-specific as well as country-specific effects. While openness does not seem to be systematically related to corporate tax rates, our findings suggest that countries compete over statutory tax rates. In contrast, we do not find competition over effective marginal rates. While the short-run impact of tax competition on corporate tax rates seems to be modest, the interplay of tax competition and a sluggish adjustment of tax rates over time implies that permanent shocks to individual countries have substantial long-run effects on equilibrium tax levels in all countries.corporate taxes, tax competition, openness
