    An Open Source Approach for Modern Teaching Methods: The Interactive TGUI System

    Full text link
    In order to facilitate teaching complex topics in an interactive way, the authors developed a computer-assisted teaching system, a graphical user interface named TGUI (Teaching Graphical User Interface). TGUI was introduced at the beginning of 2009 in the Austrian Journal of Statistics (Dinges and Templ 2009) as being an effective instrument to train and teach staff on mathematical and statistical topics. While the fundamental principles were retained, the current TGUI system has been undergone a complete redesign. The ultimate goal behind the reimplementation was to share the advantages of TGUI and provide teachers and people who need to hold training courses with a strong tool that can enrich their lectures with interactive features. The idea was to go a step beyond the current modular blended-learning systems (see, e.g., Da Rin 2003) or the related teaching techniques of classroom-voting (see, e.g., Cline 2006). In this paper the authors have attempted to exemplify basic idea and concept of TGUI by means of statistics seminars held at Statistics Austria. The powerful open source software R (R Development Core Team 2010a) is the backend for TGUI, which can therefore be used to process even complex statistical contents. However, with specifically created contents the interactive TGUI system can be used to support a wide range of courses and topics. The open source R packages TGUICore and TGUITeaching are freely available from the Comprehensive R Archive Network at http://CRAN.R-project.org/.

    Ein Pakt mit den Bürgern. Ein Interview mit Ewald Kutzenberger

    Full text link
    Das Interview mit Ewald Kutzenberger wurde von Werner Holzer und Matthias Templ am 22.10.2014 durchgeführt. Es beleuchtet den Werdegang von Ewald Kutzenberger, berichtet Hintergründe zur Entstehung des Bundesstatistikgesetzes und gibt Einblicke in den Übergang der Offiziellen Statistik in Österreich von der reinen Datensammlung zur methodischen Analyse von Daten und auch der Anknüpfung zu Universitäten. Unter anderem wird die politikberatende Funktion der Statistik in den Blickpunkt gerückt

    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    The 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

    “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

    Das Interview mit Wilfried Grossmann wurde von Werner G. Müller und Matthias Templ am 17.2.2014 durchgeführt. Es beleuchtet das historische Klima des Statistikinstitutes an der Universität Wien, die Ausrichtung der Statistik als ”breite“ Datenwissenschaft and der Universität Wien, die Kooperation mit der TU Wien und anderen Institutionen, sowie das Verhältnis zur Statistik Austria, der Amtlichen Statistik und Universitätsstatistik. Zusätzlich wird die Rolle der ÖSG und von EUROSTAT beleuchted. Das Interview widmet sich ausserdem dem Studium der Statistik im Wandel der Zeit - von Lochkarten bis zur Softwareumgebung R und Big Data. Wilfried Grossmann ist Professor für Statistik am Institut für Scientific Computing und Forschungsgruppenleiter der Arbeitsgruppe Data Analysis and Computing an der Universität Wien. Er hat ca. 100 Forschungsarbeiten publiziert im Bereich Computational Statistics, Statistisches Datenmanagement, Angewandte Statistik, Theoretische Statistik und Operations Research. Seine aktuellen Forschungsinteressen gelten dem Statistischen Datenmanagement und Informationssystemen, Statistical Computing im Bereich der Offiziellen Statistik, Statistical Knowledge Management, Statistik in der Lehre und Informatik, analytische Methoden der Statistik and Anwendungen moderner Methoden des Data Mining

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    We 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 link
    We 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 text
    We 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
