Can speech-based measures support Developmental Language Disorder identification? An explorative study.
No full textThis paper aims to identify possible phonetic biomarkers of Developmental Language Disorder (DLD) in Italian preschool children.
Speech samples, collected during three retelling tasks, were transcribed and processed through a computational pipeline. A set of acoustic and rhythmic parameters were automatically extracted from the recordings and analysed by using descriptive and inferential statistics.
Our work demonstrates that i) language difficulties of DLD take the form of reduced fluency and speech disruptions ii) some acoustical characteristics of the voice (e.g., the mean value of the fundamental frequency) can distinguish language-impaired children from peers. These results suggest that automatic voice and speech analysis could provide new markers of the DLD - markers that are not audible to the human ear and therefore fall outside the possibilities of conventional paper-and-pencil neuropsychological tests
Narrative abilities of Italian preschool children with Developmental Language Disorder
No full textOral narrative skills have shown to be a valid measure of the linguistic competence of preschoolers and a significant predictor of their academic achievements. A deficiency in this area can lead to long-term sequelae in socio-emotional well-being
in their adult life. This paper aims to provide a complete communicative picture of narrative discourse produced by monolingual preschoolers with Developmental Language Disorder (DLD) and typical peers matched by age, taking into account around fifty verbal and non-verbal features, computed on the spoken productions elicited by retelling tasks. The main finding is that although traditional standardized neuropsychological tests fail in capturing communicative deficits of DLD children, subtle but persistent language production difficulties are demonstrated by speech disruptions, reduced syntax complexity, and overt gestural signs of discomfort. This last finding is quite intriguing, considering that self- and hetero-adaptor gestures result from uneasiness and anxiety, usually escaping awareness. Taken together, the present results suggest that the observed deficits in DLD are not exclusively linguistic in nature, but may be associated with deficient planning abilities and monitoring processes difficulties

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
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
