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
Lelepa: topics in the grammar of a Vanuatu language
Get PDFThis thesis discusses topics in the grammar of Lelepa, an Oceanic language spoken by about 500 people on the islands of Lelepa and Efate in the centre of the Vanuatu archipelago.
The areas of grammar covered in the thesis are phonology (chapter 2), morphology (chapter 3), word classes (chapter 4), noun phrases (chapter 5), possession (chapter 6), clause structure and grammatical relations (chapter 7), verb classes and valency changing devices (chapter 8), the verb complex (chapter 9), complex predicates (chapter 10), aspect and modality (chapter 11), coordination and subordination (chapter 12).
The phonemic inventory is of medium to small size, with fourteen consonants and five vowels. It includes two typologically rare labial-velar consonants. Stress is not phonemic. Syllables can be complex and consonant clusters are allowed in onset and coda positions. The most important phonological process is vowel reduction, which represent a significant driver of language change.
Clausal word order is SVO. Oblique arguments follow the object(s), and adjuncts occur in initial or final position in the clause. An exception is the benefactive phrase, an adjunct encoding beneficiaries which occurs between the subject proclitic and the verb, and makes the verb complex a discontinuous structure. The benefactive phrase is cross-linguistically unusual and makes central Vanuatu languages distinctive.
Of typological interest is the split dividing objects along two classes of transitive verbs. It has its source in a semantic distinction between significantly affected Ps and less affected Ps. However, the split is lexical because borrowed transitive verbs are systematically classified with verbs taking less affected Ps regardless of the degree of affectedness of their P.
Lelepa has serial verb constructions but has also developed other verbal constructions grouped in the class of complex predicates, which comprise auxiliary verbs, serial verbs, post-verbs and viii clause-final particles. These encode a broad range of semantic distinctions including aspectual, modal and directional values, manner, intensification, cause-effect and result.
Lelepa distinguishes between inalienable and alienable possession, but the possessive constructions have diverged from the typical Oceanic model. In particular, relational classifiers are not found in the language, and a construction reflecting alienable relationships distinguishes between human and non-human possessors.
An unusual feature is the marking of mood and transitivity on certain verbs with Stem Initial Mutation. In this process, verbs switch their initial consonant from /f/ to /p/ according to particular mood and transitivity values. This process is known in Vanuatu language but often limited to mood marking, whereas Lelepa and other central Vanuatu languages also mark transitivity.
The morphological structure is agglutinative, but many grammatical features are encoded by particles, especially in the verb complex. In the nominal domain, inflectional affixes include possessor-indexing suffixes, a prefixed article and derivational affixes generating deverbal nouns. Compounding is a feature of both nouns and verbs.
Word classes are clearly defined, and the main open classes are nouns and verbs. Nominals can be derived through nominalisation of verb roots or substantivisation, a process deriving referential items from all word classes except nouns and pronouns
Lelepa texts and recordings (2006-2009)
No full textThis collection is organised around audio recordings form Lelepa, collected in 2006-2008. It includes narratives (traditional, personal), procedural texts, public speeches, elicitation (wordlists). Recordings are associated with their transcription files (.eaf, .psfx and .txt files) generated through Elan and Toolbox. Some recordings are also associated with pictures relating to the recording event
