Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Transforming Personalized Speech: Bridging the Worlds of Home, School, and Clinic for the Preschooler with Language Delays
Get PDFTeachers and speech and language therapists worked with language-delayed and language-disordered preschoolers in a program to remediate communication problems (Haas, 1993). Despite these efforts, the children failed to demonstrate generalization of learned communicative strategies across settings. Only when professionals recognized and accepted the established communicative signs of the child's home were they able to collaborate with the mothers in transforming and creating new communication patterns that met the child's needs in a variety of settings and contexts.

Dans le cadre d'un programme visant à remédier à des problèmes de communication (Haas, 1993), des enseignants et des orthophonistes ont travaillé avec des enfants d'âge scolaire aux prises avec des troubles du langage et des retards dans le développement du langage. En dépit de ces efforts, les enfants n'ont pas réussi à appliquer, d'une manière générale et dans des contextes différents, les stratégies de communication qu'ils avaient apprises. C'est seulement lorsque les praticiens ont reconnu et accepté les signes de communication établis au sein du foyer de l'enfant qu'ils ont pu collaborer avec les mères pour transformer les modes de communication existants et en créer de nouveaux qui puissent répondre aux besoins de l'enfant dans divers contextes.Educatio
Uncovering Pre-Service Teacher Beliefs about Young Children: A Photographic Elicitation Methodology
Get PDFThis illustrative paper provides an introduction to using mixed qualitative methods of photo-elicitation, face to face interviews and semiotic analysis to uncover pre-service students' beliefs about young children. The researchers share their experience on conducting a study using photo-elicitation and engaging pre-service teachers in a discussion about their beliefs of young children. The researchers found that the photo elicitation technique was useful in getting in-depth interview data but that the conversations about the photos actually entrenched students' current beliefs about children rather than provoking doubt or reflective practice. The researchers suggest that Pierce's semiotic theory holds promise for changing beliefs of pre-service teachers through the creation of a dialectic (ie, a context of reconciliation of opposing beliefs). While photo-elicitation provides a richness of data, dialogue is not enough to actually induce change.Educatio
Response to Intervention: A Cautious Tale in the Quest to Transform Lives
Get PDFThis narrative, a cautionary fictional tale, addresses the way in which theoretical models, specifically the Response to Intervention (RTI) model buckles and collapses when situated within an institutional system. The model of RTI, with its elegance and simplicity, lures educators and administrators into a predictable narrative fantasy where the learning problem resides within the student. As such, the student moves through steps or tiers where computer time, small group activities with classroom aides and volunteer tutoring masquerade as superior instruction. At the same time, each tier functions to gradually isolate the student until s/he becomes dis/abled from the larger group moving towards more restrictiveness. Regrettably, rather than dismantling the system of marginalization, RTI strengthens the organizational structure of marginalization by gradually feeding back upon itself.

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
