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
Data Friction: Physics-Inspired Metaphor to Evaluate the Technical Difficulties in Trustworthy Data Sharing
Full text linkData sharing between organizations is becoming an ever-increasing necessity. Data sharing allows organizations to improve business processes that depend on what happens in other organizations, just as having data from other organizations can enrich data analysis models. However, even though data is seen as the new oil, it does not move like oil. There are several technical and organizational factors that make data sharing difficult. In this work, inspired by the definition of friction in physics, we want to provide a first friction model that is able to capture the elements that hinder data sharing. The proposed model hypothesizes that through the adoption of data mesh in conjunction with a service-oriented sharing approach, we can utilize this model to reduce and reuse the effort for sharing data
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

Antisemitismus wird häufig mit der Zeit des Nationalsozialismus assoziiert. Die Publikation Bildungsarbeit gegen Antisemitismus, herausgegeben von Hans- Peter Killguss, Marcus Meier und Sebastian Werner, zielt mit Informationen zu Grundlagen, Methoden und Übungen darauf ab, einen Beitrag gegen die zunehmende Judenfeindlichkeit zu leisten. Der Fokus liegt dabei im Besonderen auf der schulischen und außerschulischen politischen Bildungsarbeit mit Jugendlichen. Unter anderem wird hier auf Verschwörungstheorien, die Diskriminierung von Muslim*innen und verschiedene Abwehrmechanismen nach dem Holocaust eingegangen.
Neben einem einführenden Abriss über die historische Entwicklung des Antisemitismus werden verschiedene Facetten und Formen von Judenfeindlichkeit beleuchtet. Mit der Darstellung von Möglichkeiten, Grenzen und Herausforderungen diesbezüglicher politischer Bildungsarbeit werden Pädagog*innen, wie durch die Thematisierung der Lebenswelten von Jugendlichen, Perspektiven für den Umgang mit Antisemitismus eröffnet. Darüber hinaus finden sich sowohl Einblicke in die soziale Konstruktion von Differenzen als auch in den Zusammenhang zwischen moderner Gesellschaft und Judenfeindlichkeit wieder.
Durch die methodische Verankerung der theoretischen Inhalte richtet sich die Publikation an Studierende, Praktiker*innen und Forscher*innen der Pädagogik. Ihnen wird aufgrund der Bandbreite der Themenbereiche die Möglichkeit gegeben, für ihre Zielgruppe angemessene Übungen auszuwählen. Die Theorie-Praxis-Verzahnung bietet dabei die Gelegenheit, Jugendliche auf kompetente Art für den alltäglichen Antisemitismus zu sensibilisieren
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
