No full textIl contributo presenta una ricerca, nella fascia d'età dell'obbligo scolastico, sul rapporto tra frequenza e tipologia d'uso dei dispositivi elettronici e alcune caratteristiche psico-individuali.I principali risultati hanno evidenziato come critici per gli effetti positivi vs. negativi dello smartphone: 1. i tempi di esposizione; 2.integrazione o meno con interazioni faccia a faccia e/o con i media atti a promuovere un apprendimento più personalizzato, quali libri e scrittura; 3.assistenza o meno nell'uso da parte degli dult
Il contributo delle Leiter-3 nell’assessment dell’Intelligenza fluida nei bambini con Disturbo Specifico di Linguaggio (DSL)
No full textIntroduzione
Le tradizionali batterie per la valutazione dell’intelligenza, sature di fattori verbali, sono poco adatte per alcune tipologie di individui con difficoltà nella comunicazione verbale. La Leiter- 3 (2013; standardizzazione italiana di Cornoldi, Giofrè e Belacchi, 2016) contiene stimoli per quan¬to possibile non legati al linguaggio e viene somministrata in modo completamente non verbale.
Alcuni studi hanno evidenziato che individui con DSL, che, per definizione, dovrebbero possedere abilità non verbali nella norma, presentano difficoltà anche in compiti non linguistici (es., Donlan, Cowan, Newton & Lloyd, 2007) e, in particolare, in un largo set di Funzioni Esecutive, anche quando corrette sulla base delle abilità verbali (Henry, Messer & Nash, 2012).
Obiettivo del contributo è esaminare lo sviluppo dell’intelligenza fluida in un gruppo di bambini con DSL per mezzo della Batteria Leiter-3.
Metodo
A 20 bambini italiani con DSL (E. M. = 4.95 [4.50], 30% F) sono state soministrate le prove della Batteria Leiter-3, presso la struttura sanitaria presso cui sono in carico, nel corso della standardizzazione italiana.
Risultati
Le prestazioni del gruppo sono risultate significativamente al di sotto della nor¬ma in quasi tutti gli indici e subtest, coerentemente con i dati della letteratura (Henry, Messer e Nash, 2012), e comparabili a quelle della standardizzazione statunitense (QI non verbale = 93.3). La differenza, rispetto ai punteggi normativi, è moderata nel QI e nei subtest della batteria Cognitiva, maggiore nei subtest della batteria Attenzione e Memoria (con performance prossime o al di sotto di una deviazione standard).
Conclusioni
I risultati confermano la presenza in bambini con DSL di un ampia gamma di difficoltà oltre quelle peculiarmente linguistiche. Riteniamo che sia necessario indagare sulla specificita di tale compromissione in rapporto ai diversi quadri clinici del Disturbo di linguaggio, ai fini anche di un approccio riabilitativo.

Specific weaknesses of high-functioning autistic children on the Leiter-3 International Performance Scale
Full text linkThe assessments of non-verbal intelligence in individuals with Autism Spectrum Disorder (ASD) may be subject to biases. This study compared the scores obtained on the most recent version of the Leiter scale by 18 children with high-functioning ASD and 18 typically-developing controls, who were matched for age, sex, and IQ estimated using the Raven’s Coloured Matrices. ASD children performed worse than controls on all virtually subtests and areas of the Leiter-3, including non-verbal IQ, attention-related, and working memory ability. It is suggested that the high degree of social interaction required by the Leiter-3 makes its use problematic for ASD children
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
