Compétences numériques et de calcul chez les bilingues séquentiels: une étude longitudinale
No full textL’étude présentée vise à analyser le développement des compétences
dans le nombre et en calcul dans un groupe d’enfants bilingues séquentiels.
L’étude inclut un échantillon de 133 bilingues suivis entre le début
du CE1 et la fin du CE2. Les résultats ont montré que la tâche de
calcul approximatif présentait un avantage significatif par rapport à celles
d’écriture de nombres et de tables de multiplication. Nous avons aussi
montré une réduction du pourcentage d’enfants avec des profils de difficulté
en mathématiques
Home Literacy and Numeracy Interact and Mediate the Relationship Between Socio-Economic Status and Early Linguistic and Numeracy Skills in Preschoolers
Full text linkThis longitudinal study aimed at evaluating the relationships between socio-economic status (SES) and early literacy and numeracy skills, testing home literacy and home numeracy as mediators. It also investigated the interaction of home literacy and numeracy on early literacy and numeracy skills. The study involved 310 preschool children attending the second and the third year. Parents completed questionnaires on SES and home literacy and numeracy. In the first session, children were administered language measures and non-symbolic numeracy skills and, in the second wave, tasks of early literacy and symbolic numeracy skills. Structural equation models (SEMs) showed that SES was predictive of early language and literacy skills and non-symbolic numeracy skills. In addition, home literacy and home numeracy significantly mediated the relationships between SES and children’s skills. Finally, home literacy and home numeracy showed a significant negative interaction on symbolic numeracy skills. Implications for research and educational settings are discussed
Spelling and writing skills in minority-language bilingual children exposed to a transparent orthography: multilevel profiles and concurrent predictors
Full text linkMany studies have explored how Language-Minority Bilingual Children (LMBC) read and comprehend, while the way they learn to spell and write has received less attention. This study aimed to assess a comprehensive profile of spelling and writing skills in LMBC, comparing performances of 4th and 5th grade bilingual (n = 74) and monolingual (n = 131) children in word and nonword reading and multilevel spelling and writing tasks (word, nonword and passage dictation, and written narrative production). Furthermore, we explored the role of linguistic and cognitive predictors (nonverbal Intellectual Quotient, verbal knowledge, morphosyntactic comprehension, nonword repetition) in spelling and writing outcomes. Our findings showed that overall LMBC did not reach a monolingual-like proficiency in spelling by the end of primary school, while they were similar to monolinguals in reading tasks and were able to produce written narratives with adequate macrostructure, syntactic complexity, and lexical variety. Moreover, morphosyntactic comprehension predicted spelling in both groups. Nonverbal intelligence and verbal knowledge predicted spelling skills only for the bilingual group. With regards writing skills, morphosyntactic comprehension emerged as a predictor exclusively in the bilingual group. These results are discussed with reference to educational and clinical implications
The acquisition of spelling skills in bilingual children with Italian L2
No full textThe aim of this study was to deepen the acquisition of orthographic skills and their relationship with environmental and linguistic variables in bilingual and monolingual children. The study involved 86 monolinguals and 43 bilinguals (aged 9-11 years), who were administered with reading and writing tests for words and non-words, passage dictation, narrative written production, morphosyntactic comprehension and repetition of non-words; linguistic history and socio- economic status have also been investigated. Writing seems to require longer acquisition times than reading for bilinguals, however there are some advantages in narrative production tasks. Age of exposure, verbal knowledge, morphosyntactic comprehension and reading skills seem to play an important role in predicting writing skills in the bilingual group
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
