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
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

Kausative Konstruktionen mit dem Verb "machen" im Deutschen
Get PDFUntersuchungsgegenstand der Dissertation sind sprachliche Strukturen, die aus einer Form des Verbs „machen“ und einer objektsprädikativen Adjektivphrase bestehen. Die Arbeit ist eingebettet in einen konstruktionsgrammatischen Rahmen, nach dem Sprache sich als strukturiertes Inventar von Konstruktionen (Form-Funktions-Beziehungen) beschreiben lässt. Ziele der Arbeit sind a) die korpusbasierte Ermittlung lexikalischer Kollokationen und Gebrauchstendenzen innerhalb der Zielstruktur sowie b) die systematische Beschreibung der damit verbundenen Form-Funktions-Beziehungen. Als Arbeitshypothese wurde übereinstimmend mit bisherigen Arbeiten zum selben sprachlichen Gegenstand eine kausative Bedeutung, also die Kodierung einer Ursache-Wirkung-Relation, angenommen. Da konstruktionsgrammatischen Ansätzen zufolge formale Unterschiede mit Unterschieden auf der Ebene der Funktion korrespondieren sollten, wurde empirisch untersucht, in welchen Fällen formale Unterschiede innerhalb der Zielstruktur tatsächlich systematisch zu unterschiedlichen funktionalen Interpretationen führen.
Lexikalische Kollokationen innerhalb der Zielstruktur wurden statistisch anhand von Kollostruktionsanalysen („Covarying Collexeme Analysis“; vgl. Gries/Stefanowitsch, 2004) ermittelt. Zur Beschreibung der Bedeutung oder Funktion dienten Frame-semantische Beschreibungen englischer Verben aus dem FrameNet (vgl. Fillmore/Baker, 2010).
Eine wesentliche Beobachtung besteht nun darin, dass entgegen der ursprünglichen Annahme keineswegs alle Vorkommen von „machen“ mit einer objektsprädikativen Adjektivphrase eine Ursache-Wirkung-Relation kodieren. Gerade die in der Kombination mit „machen“ hochfrequenten Adjektive korrelieren signifikant mit abweichenden, nicht im engeren Sinne kausativen, Interpretationen im Sinne der jeweils evozierten semantischen Frames.This dissertation focuses on combinations of a form of the German verb “machen” with an adjective phrase which, according to a working hypothesis, is said to have a resultative reading. The work is grounded in a Construction Grammar approach, viewing language as a structured inventory of Constructions, i.e. form-function mappings. The aims are a) establishing lexical collocations and usage tendencies within these structures involving “machen” and a resultative adjective phrase, based on corpus studies, and b) describing systematically the relevant form-function mappings. As Construction Grammar approaches predict changes in function corresponding to changes in form, the formal collocations established according to aim a) are systematically analyzed with respect to their respective functional interpretations.
The methods used involve a series of „Covarying Collexeme Analyses“ (cf. Gries/Stefanowitsch, 2004) to study lexical collocations within the given formal structure, and the application of frame semantic descriptions of English verbs, as found in FrameNet (cf. Fillmore/Baker, 2010), to the German structures found in the corpora.
The results indicate that, contrary to the working hypothesis, a great number of “machen” plus adjective tokens does not lead to a causative or resultative interpretation. Especially the most frequent adjectives combined with “machen” exhibit a significant correlation with structures evoking different, not strictly causative, semantic frames
Teaching the form-function mapping of German ‘prefield’ elements using Concept-Based Instruction
Get PDFThis publication is with permission of the rights owner freely accessible due to an Alliance licence and a national licence (funded by the DFG, German Research Foundation) respectively.Empirical findings in Second Language Acquisition suggest that the basic structure of German declarative sentences, described in terms of topological fields, poses certain challenges to learners of German as a foreign language. The problem of multiple prefield elements, resulting in ungrammatical verb-third sentences, figures most prominently in the literature. While the so-called V2 constraint is usually treated as a purely formal feature of German syntax both in the empirical as well as in the pedagogical literature, the present paper adopts a usage-based perspective, viewing language as an inventory of form-function mappings. Basic functions of prefield elements have already been identified in research on textual grammar and information structure. This paper presents results from a pilot study with Japanese elementary learners of German as a foreign language, where the form-function mapping of German prefield elements was explicitly taught following the guidelines of an approach called Concept-Based Instruction. The findings indicate that, with a focus on the function-function mapping, it is in fact possible to explicitly teach these rather abstract regularities of German to beginning learners. The participants’ language production exhibits a prefield variation pattern similar to that of L1 German speakers; at the same time the learners produce very few ungrammatical verb-third sentences.Peer Reviewe
