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
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
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
Assessing the validity of latent variables : the cases of social values and European identity
Get PDFkoamabayili/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
Zur Problematik der europäischen Identität
No full textZiel der Arbeit ist es, ein tieferes Verständnis für theoretische und empirische Probleme des Konzepts europäische Identität zu gewinnen.
Der theoretische Stellenwert des Konstrukts europäische Identität ist umstritten. Einerseits liefern die politikwissenschaftliche Demokratietheorie und die Theorie des kommunikativen Handelns von Jürgen Habermas gute Gründe für die politische Forderung nach einer europäische Identität. Andererseits zeigt die soziologische Kritik von Günter Dux, dass insbesondere der Mainstream der politischen Theorie aber auch Habermas einer unrealistischen Konzeption von Gesellschaft aufsitzt.
Die theoretische Problematik des Konzepts europäische Identität hat im Kern wenig „Europäisches“, sie liegt vielmehr in den Problemen und Missverständnissen begründet, die den Begriff der Identität, insbesondere jene der kollektiven Identität in den Sozialwissenschaften begleiten. Eine soziologisch brauchbare Konzeption darf europäische Identität nicht essentialisieren, als gegeben festschreiben. Europäische Identität als politische Identität muss als Repräsentation der sozialen Relation von europäischen Bürgern und dem politischen System der EU bestimmt werden. Analytisch lässt sich jede kollektive Identität durch ihre spezifischen Inhalte und durch den Grad der Umstrittenheit dieser Inhalte näher charakterisieren.
Die größte Problematik der quantitativen empirischen Messung von europäischer Identität liegt darin, dass die Operationalsierungen die Inhalte der Europäischen Identität gar nicht spezifizieren. An Daten des Projekts „Youth and European Identity“ wird mit Hilfe von faktoranalytischen Messmodellen im Rahmen des Ansatzes allgemeiner Strukturgleichungsmodelle gezeigt, dass derartige Messinstrumente im internationalen Vergleich nur äußerst eingeschränkt valide sind. Abschließend werden empirische Indizen für unterschiedliche Inhalte der europäischen Identität aufgezeigt und das neue Messmodell von Micheal Bruter diskutiert, das in kulturelle und politische („civic“) Inhalte der europäischen Identität unterscheidet.The aim of the diploma thesis is to gain a deeper understanding of theoretical and empirical problems of the concept of European identity.
The theoretical significance of the construct European identity is contested. On the one hand the theory of democracy in political science and theory of communicative action by Jürgen Habermas give good reasons for politics to claim a European identity. On the other hand the sociological critique of Günter Dux shows that especially the mainstream of political science but also Habermas are trapped in an unrealistic conception of society.
The core of the theoretical problem of European identity is not so “European”, but to a much larger extent related to problems and misunderstandings of the concept of identity, especially of collective identity in the social sciences in general. A sociologically useful conception must not essentialise European identity. European identity as a political identity has to be defined as a representation of the social relation of European citizens and the political system of the EU. Analytically every collective identity can be further characterised by its content and the contestation of its content.
The crucial problem of the quantitative measurement of European identity is the fact that the operationalizations do not specify any content of European identity. Drawing on data of the project “Youth and European Identity” and using factor-analytic measurement models in the framework of structural equation modeling these measurement instruments turn out to be of very limited validity in international comparisons. Finally empirical evidence for the varying content of European identity is presented and new measurement model by Michael Bruter which differentiates between a cultural and a civic content of European identity is discussed
