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
Suspended Affixation needs no morphological word: The suffix -(y)Ip
Full text linkI re-evaluate the morphological word constraint for suspended affixation(SA) in Turkish (Kabak 2007). I argue that SA, as an operation, is not bound by the morphological word constraint. What is constrained is the exponent insertion and SA takes place before it. SA is a morphological ellipsis taking place in conjunctions. After suspension, conjunction peripheral affixes are interpreted for all the conjuncts. The morphological word constraint in Turkish is related to SA in verbals, and it defines the limit of suspendability for an affix. This limit is defined by Kabak to be the morphological word. What is left of the conjunct after suspension should be a morphological word, otherwise the derivation is ungrammatical. To show that this is not the case, I propose a different analysis for the suffix -(y)Ip and provide empirical points for its relation to SA
Compositional Analysis of Turkish Agent Nominalizers
Full text linkI propose analyses for the Turkish agent nominalizers -(y)IcI and -CI. I modify the denotation for the Sakha agent nominalizer -AAccI (Baker & Vinokurova 2009) because the denotation for -AAccI formally allows for readings that are unattainable by -(y)IcI in Turkish. I change the domain of the suffix\u27s denotation and the unattainable reading is rendered out. The analysis for -CI makes use of indices from the context and arrives at a relation to be established between the base and the derived nouns. I use context dependent readings to argue for using context dependent indices. Both analyses have the compositional properties of pseudo-incorporation to account for the non-referential readings of the internal argument in -(y)IcI and the noun base for -CI
