Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Doing good with VR: Retrospektive Interviews
No full textPolitischen Abstimmungen geht eine Phase des sich Informierens voraus. Das «Abstimmungsbüchlein» spielt dabei eine wichtige Rolle. Die Textlastigkeit des Büchleins kann aber dazu führen, dass die darin präsentierten Informationen oft schwer verständlich sind, was zur Folge hat, dass es zu nicht informierten Entscheidungen kommt. Dies zeigt sich in Aussagen wie „Hätte ich das gewusst, hätte ich ...“ oder „Es war schwierig, die Vorlage zu erklären“. Im Rahmen dieses Forschungsprojektes soll daher der Frage nachgegangen werden, ob und inwieweit Virtual Reality (VR) dazu beitragen kann, wie das Stimmvolk die zur Abstimmung präsentierten Informationen versteht und so informierter entscheidet. Inhalt und Ziel des Forschungsprojektes Das primäre Ziel des Forschungsprojektes ist es, zu untersuchen, wie sich VR auf die politische Entscheidungsfindung auswirkt, und zwar im Vergleich zu den klassischen und noch immer aktuellen textbasierten Abstimmungsbroschüren. Dazu nutzen wir methodisch das klassische psychologische Experiment, um Faktoren von Interesse zu isolieren und so deren Einfluss durch systematische Variation zu untersuchen (z. B. wie Argumente, die für oder gegen eine Abstimmungsvorlage sprechen in VR im Gegensatz zu Broschüren verarbeitet werden). Die Experimente werden zudem durch weitere Methoden wie Eye-Tracking und Think-Aloud Protokolle gestützt. Das Projekt soll Kenntnisse zutage fördern, wie VR die politische Entscheidungsfindung verändern kann und welche Faktoren dafür verantwortlich sein können. Wissenschaftlicher und gesellschaftlicher Kontext des Forschungsprojektes Mit dem Forschungsprojekt wollen wir erste Ideen entwickeln, wie die VR-Technologie im Bereich der politischen Entscheidungsfindung, d.h. für zukünftige Volksabstimmungen, genutzt werden kann.Political votes are preceded by a phase of informing oneself. The "voting booklet" plays an important role in it. However, the text-heavy nature of the booklet can mean that the information presented in it is often difficult to understand, with the result that uninformed decisions are made. This is reflected in statements such as "If I had known that, I would have ..." or "It was difficult to explain the topic." This research project will therefore investigate the question of whether and to what extent virtual reality (VR) can contribute to how the electorate understands the information presented and thus makes more informed decisions. Content and aim of the research project The primary goal of the research project is to investigate how VR affects political decision making, in comparison to traditional and still current text-based voting brochures. To this end, we methodically use the classical psychological experiment to isolate factors of interest and thus investigate their influence through systematic variation (e.g., how arguments in favor or against a voting proposal are processed in VR as opposed to brochures). The experiments will also be supported by other methods such as eye-tracking and think-aloud protocols. The project aims to unearth knowledge of how VR can change political decision-making and what factors may be responsible. Scientific and social context of the research project With this research project we want to develop first ideas on how VR technology can be used in the field of political decision making, i.e. for future referendums

Variations on the Author
Get PDF“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
Get PDFWe 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
