On the stability of the localized single-valued extension property under commuting perturbations
No full textThis article concerns the permanence of the single-valued extension property at a point under suitable perturbations. While this property is, in general, not preserved under sums and products of commuting operators, we obtain positive results in the case of commuting perturbations that are quasi-nilpotent, algebraic, or Riesz operators
What Counts Most in Assessing Emergent Literacy With Digital Tools?
No full textThe concept of emergent literacy presents the view that from the time they are born, young children develop their knowledge about language and literacy through their sociocultural interactions with others. Emergent literacy encompasses knowledge about the alphabet, letter sounds, words, and language, and such skills are predictive of future reading, writing, and spelling ability. However, some emergent literacy skills are stronger predictors than others. For example, letter name and sound knowledge and phonological awareness are strong predictors, whereas print concepts and oral language are moderate predictors.1 Emergent literacy is more than discrete skills, with complex interrelationships. It is also important to note the influence of the literacy environment on each child’s learning in the years prior to school.No Full Tex

The Impact of Tablets and Apps on Language Development
No full textYoung children's development of early literacy and language skills are strong predictors of future reading and writing ability. These skills in turn predict future health, well‐being, and success. It is important that young children are provided with positive experiences that foster these skills. In the 21st century, such early learning can occur through interactions with both non‐digital and digital forms of language and print. Much work has been done on early learning with non‐digital resources, such as exploring paper‐printed books, reading words on products and signs, and writing with traditional tools such as pencils and paint brushes. The benefits of these non‐digital tools and experiences for literacy and language learning have been well established. With the introduction of new digital technologies, such as mobile phones, touch screen tablets, and associated apps, an understanding of the impact of digital experiences on children's development is emerging.Full Tex
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
