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
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
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
Das Pop-up-Ikonogramm - Entwicklung und Evaluation einer multicodalen Instruktionsform für mathematische Lerninhalte
Full text linkThis dissertation first gives a short overview of the results and theories of appropriate approaches to research concerning media, respectively cognitive psychology. These approaches deal with the learning effectiveness of different forms of representation, respectively with their optimum design. Parallel to the representation of the research results, possible implications for the representation of mathematical contents are shown. The first part of the overview starts with considerations concerning the meaning of traditional representation forms of combinations of a text and a single picture and an educational film for the transfer of mathematical contents. It is followed by a short analysis and evaluation of the state of research concerning learning with different representation forms as well as various classifications of picture types. After these preliminary remarks, different modifications are discussed and demonstrated by the proof of the intersecting chords theorem, based on the classic representation forms of mathematical contents - the combination of single pictures with explanatory texts. At first it is considered how to graphically optimise the classic text-single picturecombination. In the next step it is modified gradually by separating it into text sections with the corresponding picture parts, by areal structuring as well as by separating the detail information by creating different views. As a result, an entirely new form of representation has developed. In the second part a new form of representation of the mathematical educational film is also discussed and modified by, for instance, adding control elements and by separating it into single sequences. This is also substantiated by the example of the proof of the intersecting chords theorem. In the following sections it is shown how the two independent proposals developed before concerning the representation of text-picturecombinations, respectively educational filmscan, can be integrated in a new form of representation, namely the pop-up-iconogram. Following that the didactic value of this form of representation is discussed, taking the mathematical competence and learning stage of the learner into consideration. After a section with directions on how to design pop-up-iconograms some exemplary implementations of pop-up-iconograms for different topics are introduced. This chapter is completed with exemplary considerations about integrating pop-up-iconograms in learning environments. In the third part of this dissertation an empirical study concerning the learning effectiveness and acceptance of pop-up-iconograms is described. This study was executed as a summative evaluation of this form of representation in 2003 at the University of Erlangen-Nürnberg. After developing adequate questions and hypotheses, a three-step examination structure is designed: pretest, instruction and a measurement of learning success. This is intended, in particular, to answer the central question of the learning effectiveness of pop-up-iconograms, especially in comparison with classic representation forms, like a text-picturecombination or an educational film as well as various other representation forms, which are derived from the single structure criteria of the pop-up-iconogram. When measuring the learning success, the reproduction and transfer performance are considered separately. The test situation does not completely correspond to reality, as the pop-up-iconogram could not be integrated yet in a more extensive multimedia-based learning environment. After describing the examination exactly, the survey data is statistically evaluated and its content is interpreted. The main focus here is the question of the learning effectiveness of the pop-up-iconogram as well as the possible influences of the effects of learning time. Further evaluations and results follow regarding additional questions, e.g. the acceptance of this representation form. In conclusion, the research efforts are evaluated and a prospect is given about future research options in the field of pop-up-iconograms.Die Arbeit gibt zunächst einen Überblick über Ergebnisse und Theorien einschlägiger medien- bzw. kognitionspsychologischer Forschungsansätze, die sich mit der Lernwirksamkeit unterschiedlicher Repräsentationsformen bzw. mit Fragen einer möglichst optimalen Gestaltung derselben auseinandersetzen. Hierbei werden stets parallel zur Darstellung der Forschungsergebnisse mögliche Implikationen für die Repräsentation mathematischer Inhalte aufgezeigt. Der erste Teil des Überblicks startet mit Überlegungen zur Bedeutung der traditionellen Repräsentationsformen Text-Einzelbild-Kombination und Lehrfilm für die Vermittlung mathematischer Inhalte. Dem folgt eine kurze Analyse und Bewertung des Forschungsstandes zum Lernen mit unterschiedlichen Repräsentationsformen sowie verschiedener Klassifizierungen von Bildtypen. Nach diesen Vorbemerkungen werden ausgehend von der klassischen Darstellungsform mathematischer Inhalte – der Kombination einzelner Bilder mit erläuternden Texten –verschiedene Modifikationen diskutiert und exemplarisch am Beweis des Sehnensatzes demonstriert. Werden zunächst nur gestalterische Überlegungen zur Optimierung der klassischen Text-Einzelbild-Kombination angestellt, so wird diese schließlich schrittweise durch Zerlegung in Textabschnitte mit entsprechenden Teilbildern, räumlicher Strukturierung der Darstellung sowie zuletzt durch Trennung der Detailinformationen durch Bildung verschiedener Ansichtsebenen soweit modifiziert, dass eine völlig neue Darstellungsform entsteht. Ebenso wird in einem zweiten Strang die Repräsentationsform des mathematischen Lehrfilms diskutiert und etwa durch Zufügen von Steuerelementen sowie durch Zerlegung in einzelne Sequenzen modifiziert. Dies wird ebenfalls am Beispiel des Sehnensatzbeweises konkretisiert. In den folgenden Abschnitten wird dargestellt, wie mit dem Pop-up-Ikonogramm die beiden zuvor entwickelten unabhängigen Vorschläge für die Gestaltung von Text-Bild-Kombinationen bzw. Lehrfilmen zu einer neuen Darstellungsform, dem Pop-up-Ikonogramm, zusammengefasst werden können. Dem schließen sich Überlegungen zum didaktischen Mehrwert dieser Repräsentationsform unter besonderer Berücksichtigung der mathematischen Kompetenz und dem Lernstadium eines Lerners an. Nach einem Abschnitt mit Hinweisen zur Gestaltung von Pop-up-Ikonogrammen werden einige exemplarische Umsetzungen von Pop-up-Ikonogrammen zu unterschiedlichen Themengebieten vorgestellt. Abgeschlossen wird dieses Kapitel mit exemplarischen Überlegungen zur Integration von Pop-up-Ikonogrammen in Lernumgebungen. Im dritten Teil der Arbeit wird eine empirische Untersuchung zur Lernwirksamkeit und Akzeptanz von Pop-up-Ikonogrammen beschrieben, die als summative Evaluation dieser Darbietungsform 2003 an der Universität Erlangen-Nürnberg durchgeführt wurde. Nach der Entwicklung geeigneter Fragestellungen und Hypothesen wird ein dreistufiges Untersuchungsdesign entworfen, welches insbesondere die zentrale Frage nach der Lernwirksamkeit von Pop-up-Ikonogrammen gegenüber klassischen Repräsentationsformen, wie Text-Bildkombination bzw. Lehrfilm, in einer klinischen Testsituation beantworten soll. Im Anschluss an die genaue Beschreibung der Untersuchung, in der verschiedene Repräsentationsformen miteinander verglichen wurden, die aus einzelnen Strukturmerkmalen des Pop-up-Ikonogramms abgeleitet werden, erfolgt eine statistische Auswertung und inhaltliche Interpretation der erhobenen Daten. Hierbei steht zunächst die zentrale Frage nach der Lernwirksamkeit des Pop-up-Ikonogramms im Vordergrund. Weitere Auswertungen und Ergebnisse zu ergänzenden Fragen, wie etwa die nach der Akzeptanz der Repräsentationsform, schließen sich an. Abschließend wird eine Bewertung der unternommenen Forschungsbemühungen versucht sowie ein Ausblick auf zukünftige Forschungsmöglichkeiten im Bereich der Pop-up-Ikonogramme gegeben
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
