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

The Role of Teacher-Child Interaction Quality in the Relationship Between Approaches to Learning and Academic Skills in Head Start Classrooms
No full textThe current study examined (a) the direct association between teacher reports ofchildren’s approaches to learning and direct assessments of language, literacy, andmathematics skills in a sample of diverse, low-income preschool children, and (b) theextent to which the association between preschool children’s approaches to learning andacademic skills was dependent upon teacher-child interactions. Multilevel models wereestimated using data from a sample of urban Head Start children (N = 301 children across53 classrooms). Findings showed direct associations between attention persistence andchildren’s literacy and mathematics skills, as well as between attitude toward learningand literacy skills. Classroom organization quality was positively associated withchildren’s literacy skills, and instructional support was positively related to language,literacy, and mathematics skills. Cross-level interactions indicated that higher levels ofemotionally supportive teacher-child interactions strengthened the relationship betweenattitude toward learning and children’s literacy skills. Findings suggest classroomscharacterized by respectful, warm, and supportive teacher-child interactions can benefitchildren’s approaches to learning and academic skills. Implications for future research,policy, and practice are discussed.</p

Identifying Patterns of Approaches to Learning in Head Start: A Strength-Based, Ecological Perspective
No full textChildren exhibit wide individual variation in their approaches to learning skills at preschool entry and very little is known about the extent to which proximal factors within home and school learning contexts support the development of positive approaches to learning. To address these gaps, the current study leveraged the Head Start Family and Child Experience Survey (FACES 2014) nationally representative sample of Head Start children: (1) to identify profiles of children’s approaches to learning in Head Start; (2) to examine stability and change in profiles of approaches to learning across a Head Start year and home- and classroom-level factors associated with stability and change; and (3) to examine differential associations between patterns of approaches to learning and gains in academic skills. Findings revealed three profiles of children’s approaches to learning that demonstrated structural stability across the year. Children displayed individual stability and change across profile transitions. The quality of teacher-child interactions was associated with approaches to learning profile transition patterns. Finally, profile patterns characterized by positive approaches to learning were associated with greater academic gains. Results from this study contribute to early childhood research and practice by identifying key classroom factors that contribute to patterns of children’s approaches to learning. Finally, results offer insight to policymakers when allocating resources to enhance programs supporting children’s development. </p
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
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
