    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 PDF
    We 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

    Birds and babies : a comparison of the early development in vocal learners

    This thesis provides a comparison of mostly perceptual development during vocal learning in songbirds (zebra finches) and human infants. The aim is to disentangle experience dependent and independent processes during vocal learning. In both human infants and juvenile songbirds, a perceptual preference for __universal__ sounds was found, independent of adult auditory input. Later in development, both infants and juvenile songbirds show a change is preference. The juvenile songbirds clearly change their preference towards sounds they have been auditorily exposed to (chapter 3). In human infants in the influence of experience is less clear in this thesis. In combination with previous literature the most likely scenario is a combination of experience dependent and independent processes (chapter 2). To further compare human and birdsong phonology, a __typology__ of zebra finch song elements was performed (chapter 4). The results of this study indicate commonality as well as variation between populations in terms of phonology. In the order of elements within a sequence however, there is little evidence for common patterns across populations and there is variation within and between populations. In summary, this thesis shows similarities in developmental mechanisms in two vocally learning species. There might be a link between development and typology.UBL - phd migration 201

    Building a Phonological Inventory

    Get PDF
    The Feature Co-occurrence Constraint theory proposed in this dissertation provides a means to capture the development of the language-learning child's segment inventory. It does this by combining a growing set of features with constraints that are automatically activated as soon as these features are acquired. Representation and derivation go hand in hand, and develop together during acquisition. The Feature Co-occurrence Constraint theory builds on a minimal view of phonology, where the inventory is seen as epiphenomenal rather than a mentally ‘real’ object, features are few and monovalent, and the constraint set is limited to no more than two types. The theoretical consequences of the proposal for both feature theory and constraint theory are worked out in detail and a thorough discussion of phonological acquisition is provided, making this book of interest to both theoretical phonologists as acquisitionists.Language Use in Past and Presen

    Dispelling the Myths Behind First-author Citation Counts

    Get PDF
    We 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

    We 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
