The usability of a Norwegian adaptation of the Childrens Communication Checklist Second Edition (CCC-2) in differentiating between language impaired and non-language impaired 6-to 12-year-olds
No full textThe usability of a Norwegian adaptation of the Childrens Communication Checklist Second Edition (CCC-2) in differentiating between language impaired and non-language impaired 6- to 12-year-olds. Scandinavian Journal of Psychology. The aim of the present study was to evaluate if the Norwegian adaptation of the Childrens Communication Checklist-2 (CCC-2) differentiates between a language impaired and a non-language impaired population and to make a first evaluation of the psychometric qualities of the questionnaire on a Norwegian sample. A total of 153 children aged 6-12 years participated in the study (45 language impaired and 108 non-language impaired). The Norwegian adaptation of the CCC-2 distinguished language impaired from non-language impaired children and thus seems to provide a useful screening tool for communication impairments in Norwegian children. The reliability of the CCC-2 appeared to be reasonable with internal consistency values ranging from 0.73 to 0.89.This is the author version of the following article:Wenche Andersen Helland, Eva Biringer, Turid Helland and Mikael Heimann , The usability of a Norwegian adaptation of the Childrens Communication Checklist Second Edition (CCC-2) in differentiating between language impaired and non-language impaired 6-to 12-year-olds, 2009, SCANDINAVIAN JOURNAL OF PSYCHOLOGY, (50), 3, 287-292.which has been published in final form at: http://dx.doi.org/10.1111/j.1467-9450.2009.00718.xCopyright: Blackwell Publishing Ltdhttp://www.blackwellpublishing.com
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
Sammenligning av engelskkunnskaper hos to grupper 6. – 7. klassinger undervist etter henholdsvis L97 og K06
No full textI denne artikkelen sammenlignes muntlige og skriftlige engelskferdigheter hos en gruppe 6.-7.klassinger i 2001, i hovedsak undervist etter L97, og en gruppe 6.klassinger i 2009, i hovedsak undervist etter Kunnskapsløftet 2006 (K06). Siden elevene undervist etter K06 i sum har hatt flere år og flere undervisningstimer i engelsk, forventet vi at de skulle gjøre det bedre enn elevene undervist etter L97. Dataene våre signaliserer at dette ikke er tilfelle. Elevene ble testet individuelt, og deres språkforståelse og produksjon ble kartlagt. Gruppen undervist etter K06 viste svakere resultat på grammatisk kompetanse og metakunnskap om språket enn gruppen undervist etter L97, mens de var noe bedre til å snakke fritt. Resultatene blir diskutert på bakgrunn av de aktuelle læreplanene, elevenes kognitive utvikling, lærerkompetanse, nasjonal og internasjonal forskning på språklæring.</jats:p
Trends in Dyslexia Research during the Period 1950 to 2020—Theories, Definitions, and Publications
Full text linkIntroduction. The focus of the present paper is on (1) how dyslexia research and hence definitions have developed during the period 1950–2020 and includes (2) a database search of scientific publications on dyslexia during the same period. The focus is on the definitions of dyslexia and the organization of the network search based on the causal four-level model by Morton and Frith. Method. (1) The definitions are presented in accordance with a historic review of dyslexia research from 1950 to 2020 and based on (2) Google Scholar counts of publications on dyslexia, on defining dyslexia, on dyslexia at the four levels (symptomatic, cognitive, biological, environmental), and by areas (sensorimotor, comorbidity). Finally, a percentage calculation shows the relative development within each level and area by decennium (1950–1960, 1960–1970, 1970–1980, 1990–2000, 2002–2010, 2010–2020). Results. (1) Of the seven definitions presented, only the definition by the BDA 2007 included the four levels of the causal model. (2) The number of publications increased substantially over the period. However, relatively few publications have defined dyslexia. An increase in publications from 1950 to 2020 was seen across the four levels and two areas—however, with an alteration in the thematic focus over this time span. Summary. Defining dyslexia has still not reached a consensus. This uncertainty may explain why only one of the seven definitions proved satisfactory according to the four-level model. Along with the general increase in research, publications on dyslexia have increased accordingly during the period 1950 to 2020. Although the symptomatic level has played a dominant role over the whole period, thematic shifts have been seen over these 70 years. In particular, a substantial thematic shift was seen by the turn of the millennium. There has been a relative increase in the focus on literacy at the symptomatic level, on phonological awareness at the cognitive level, in gender at the biological level, and second language learning as comorbidities. However, increases in counts are not alone a valid indication of scientific progress. In particular, the lack of definitional criteria as a basis for participant and method selection should attract much more focus in future studies. The present study underlines the multifactorial nature of dyslexia, as evidenced by a substantial increase in the number of publications on the subject. It is a challenge for future research to continuously use and possibly redefine dyslexia definitions in line with such standards
