Prosodia e complessità linguistica nella sindrome di Williams
No full textVengono presentati i risultati di una ricerca sull’interazione tra prosodia e complessità sintattica in un ragazzo con sindrome di Williams, un bambino di controllo per età mentale e un ragazzo di controllo per età cronologica. L’obiettivo era di verificare l’esistenza di un deficit nella gestione della modulazione tonale della complessità linguistica attraverso la partecipazione a una conversazione semistrutturata con un operatore. I risultati suggeriscono che il ragazzo con SW presenti marcate difficoltà rispetto ad entrambi i partecipanti di controllo nella complessità sintattica,
sia a livello frasale sia discorsivo. A livello discorsivo il ragazzo con SW sembra aver sviluppato una strategia adattativa, giustapponendo gli enunciati a formare coppie il cui collegamento esplicito è lasciato alle abilità di inferenza comunicativa dell’interlocutore. Il profilo della frammentazione melodica risulta rilevante a livello clinico, poiché permette di cogliere un’atipicità di profilo specifica, che potrebbe rendere ragione del profilo «cantilenante», e suggerisce la possibile esistenza
di una difficoltà nella coordinazione dei rapporti di interfaccia tra componenti prosodiche e linguistiche.We present a preliminary investigation on prosody and complex syntax in a boy
with Williams syndrome, one mental age matched control and one chronological age matched control.
We aimed at verifying the existence of a deficit at the prosody/syntax interface in a language
sample elicited by means of a conversational task. Results hint at a specific deficit in accessing
syntax at sentence and discourse levels for the boy with Williams syndrome with respect to both
controls. However, at a discourse level the boy with Williams syndrome seems to have developed
an adaptive strategy in resorting to utterance juxaposition which makes his production superficially
similar to that of the chronological age control, but which charges the communicative partner with
the burden of inferring the appropriate implicit connection. Indices of prosodic fragmentation are
of clinical relevance: they may account for the singsong intonation and suggest the existence of a
planning and coordination deficit at the interface between the prosodic and linguistic components
of the utterance process

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
