The psychological validity of formational parameters in native and non-native signers of British sign language
No full textThis thesis presents four experimental studies that aim to assess the validity of formational parameters as psychological constructs. The studies employ two experimental paradigms - ordered recall of lists and form priming - with three groups of experimental participants - hearing sign language learners, deaf people who learned sign as a first language (native signers), and deaf people who learned sign language after the age of 6 years (non-native signers). The studies were designed to assess whether sign language was internalised as a formational or morphological code.Findings from the studies using ordered recall of lists are equivocal, supporting neither formational nor morphological coding. It is proposed that (a) more accurate measures of similarity are required, and (b) it is important to consider the number of items recalled from a list when assessing the effect of list similarity on order errors - findings reported in previous studies have failed to do this.The study employing a form priming procedure produced more substantive findings. Clear differences were evident in how signs were processed by native and non-native signers. Non-native signers appeared to process signs in terms of global visual characteristics, whereas native signers processed signs in terms of formational parameters. The role of morphological parameters was not assessed. It is concluded that form priming procedures stand to offer more valid and valuable insights than list recall studies, and a model of access to the sign lexicon is proposed for further empirical investigation.</p
Phonological priming in British Sign Language
No full textModels of lexical access seek to explain how incoming language data is mapped onto long-term lexical representations. The experiment reported here aims to provide insight into which elements of language input are used for mapping onto a sign language lexicon. Rather than using the organs of the vocal tract, sign languages use the arms, hands, body and face to create meaning, combining handshapes, locations and movements to create meaningful words (signs). This study aims to determine whether these parameters are also used in lexical access processes. Twelve deaf native and twelve deaf non-native signers of British Sign Language (BSL) were presented with a primed lexical decision task. They were required to make a lexical decision about a target sign after viewing a preceding prime that was phonologically related to the target. Analysis of the data suggests that native signers use phonological information in signs in order to access their mental lexicon. Moreover, it appears that the salient parameter in the input is a combination of location and movement – only when both these parameters are shared by prime and target is facilitatory priming observed. There was no evidence that non-native (deaf) signers used phonological parameters to access their lexicon, despite a high degree of success in the lexical decision task at a speed comparable to that of native signers. These findings are discussed in relation to sign language acquisition and the development of phonological theories of signed languages
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
