A Collaborative Lecture in Information Retrieval for Students at Universities in Germany and Switzerland
Get PDFK3, work in progress, is an acronym for Kollaboration (collaboration), Kommunikation (communication), and Kompetenz (competence). K3 provides a platform in the context of knowledge management to support collaborative knowledge production in learning environments. The underlying hypothesis states that collaborative discourse conciliates information as well as communication competence in learning contexts. The collaborative, communicative paradigm of K3 is implemented by asynchronous communication tools as a means of constructivist learning methodology. In this paper we will describe a K3 course. The lecture was organized and carried out at two places in two different countries (Germany and Switzerland) with students from different universities in the context of Library and
Information Science. The paper informs about the management of the lecture and about the problems we had to run the lecture at two places. The circumstances in coordinating the presentations, the exercises, the examinations and evaluation, and the time schedule are presented. The conclusions of the lecturers and the results of a questionnaire for the students are explained in detail
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
Bildungsforschung in Deutschland - eine Situationsanalyse
Get PDFMit der vorliegenden neuen Bestandsaufnahme möchte das Deutsche Institut für Internationale Pädagogische Forschung (DIPF) der Interdisziplinarität des Forschungsfeldes besser gerecht werden, als frühere Berichte dies leisten konnten: Angehörige beider Arbeitsbereiche des DIPF – Bildungsforschung und Bildungsinformation – verfolgen gemeinsam das Ziel, die Bildungsforschung in ihrer ganzen Bandbreite zu erfassen. Sie arbeiten mit einer im Vergleich zu früheren Studien erweiterten Datenbasis, die durch zwei aufwendige zusätzliche Erhebungen generiert wurde. So dienten Internetrecherchen dazu, das potenzielle Personal der Bildungsforschung an wissenschaftlichen Hochschulen und außeruniversitären Forschungseinrichtungen so erschöpfend wie möglich zu erfassen. Für die Analyse der Qualifizierungsschriften wurden zudem erstmals Informationen aus verschiedenartigen Datenquellen zusammengeführt und homogenisiert, was die Analysebasis ebenfalls wesentlich erweitert.

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

eine bibliometrische Analyse des Forschungsfeldes
Get PDFDas Forschungsfeld der Bildungsforschung befindet sich seit der ersten PISA-Studie in einer starken Expansionsphase. Bisherige Analysen dieses Feldes beschränken sich allerdings auf allgemeine Übersichten zu verschiedenen Aspekten, etwa zum Personal, zur Finanzierung, zu Forschungsprojekten oder zu Publikationen. Das Ziel der Dissertation ist es dagegen, speziell die kognitiven Strukturen der Bildungsforschung in Deutschland, und hier insbesondere die in diesem Feld behandelten Forschungsthemen sowie seine Wissensbasis, mittels der bibliometrischen Methoden der Kowort- und der Referenzanalyse zu untersuchen. Die Datengrundlage bildeten zum einen die Schlagwörter zu 23389 Publikationen des Zeitraums 2000 bis 2009, die durch eine schlagwortbasierte Suche in der FIS Bildung Literaturdatenbank ermittelt wurden. Zum anderen die in den Beiträgen der dritten Auflage des Handbuchs Bildungsforschung zitierten 3921 Referenzen. Die Ergebnisse der Referenzanalysen zeigen eine nach wie vor sehr große Bedeutung der Publikationstypen Monographie und Sammelband und einen relativ starken nationalen Fokus im Zitationsverhalten, aber auch große Unterschiede in den Zitationsmustern zwischen den einzelnen Beiträgen. Zudem zeigt sich, dass die Schulleistungsstudien und die Bildungsberichte die einflussreichsten Publikationen der aktuellen Bildungsforschung darstellen und die Pädagogik, die Soziologie, die Psychologie sowie die Wirtschaftswissenschaften die wichtigsten Bezugsdisziplinen. In der Analyse der thematischen Schwerpunkte bestätigt sich die zentrale Rolle des Themenbereichs Schülerleistung und ist ein Bedeutungszuwachs der Forschung zum Thema Lernen zu erkennen. Aus den Analysen lässt sich folgern, dass Handbücher eine informative, aber noch wenig genutzte, Datenquelle der Wissenschaftsforschung darstellen. Ferner sind mit der Methode der Kowortanalyse auch differenziertere Untersuchungen von Forschungsfeldern, die nicht gut in Zitationsdatenbanken abgedeckt sind, möglich.Since the first PISA study the field of educational research is going through a phase of strong expansion. Previous analyses of the field are largely confined to general overviews of various aspects like scientific staff, funding, research projects or publications. The aim of the thesis, in contrast, is to study the cognitive structures of educational research in Germany, in particular the research topics and the knowledge base of the field, using the bibliometric methods of co-word analysis and reference analysis. Two data sources were used: the keywords of 23389 publications from the period 2000 to 2009. These publications were identified by a keyword-based search in the German Education Index. And the 3921 references cited in the articles of the third edition of the Handbuch Bildungsforschung. The results of the reference analysis show a high relevance of the document types monograph and edited book and a relatively strong national focus but also considerable differences in the citation patterns of the individual articles. Furthermore, student assessment studies and education reports are the most influential publications of current educational research and pedagogy, socioloy, psychology and economics the main reference disciplines. The analysis of the thematic priorities reaffirms the central role of the topic student achievement and shows a growing importance of the issue of learning. It can be concluded that handbooks are an informative but still largely unexplored data source in science studies. Moreover, the method of co-word analysis facilitates more detailed investigations of research fields that are not well covered in citation indexes
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
