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
Preschool children’s grouping: the role of social context.
No full textDuring preschool age, children make their social experience mainly in two contexts, family and class (Hinde, 1974; 1987). Within the class, children, while playing or making activities, compose different kinds of groups (single, dyads, triads, or large groups). Although the group issue has been considered critical at older ages e.g. during adolescence, ethological studies (Strayer & Santos, 1996; McGrew, 1972; Barbu, 2003) have underlined that the group is a core theme since early ages. However, relatively few empirical data have been collected on preschool grouping within the class.
The goal of this research is to describe the types of groups built by preschool children in the naturalistic setting of the class. In particular, our study aimed at understanding whether the kind of situation (child led vs teacher led) affects the number of participants per group, the size of the group and the affiliation in the group according to gender.
Method
Data were collected in 6 Italian preschool settings homogeneous for the age of the children, from the end of the second year (mean age 4.5) to the end of the third school year (mean age 5.5). The mapping methodology, developed by Peter Kutnick (Kutnick, Blatchford, & Baines, 2002) was used to obtain, as a snapshot, a map of the groups present in the class. A total of 77 mappings were collected with 515 groups: 133 teacher-led and 382 child-led. Results and discussion
The results showed that groups were larger in the teacher led than in the child led situation and that when teachers lead the children’s social experience large groups with mixed gender are formed more frequently. By contrast, when children lead their social experience, they make smaller groups (solitary and dyads), frequently with peers of the same gender. Therefore, the context (teacher vs child led) should be taken into account in order to fully understand children’s social experience in school grouping
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
