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
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
Exploring Culturally Informed Approaches to Book Read-Aloud with Young Children
Get PDFEarly childhood is a critical period for language and literacy development. One-way adults introduce children to the world of books is through picture books read-aloud. Adults from different cultural background engage in this activity differently, and to date, the early childhood field has emphasized a constructivist approach to book reading typical in individualistic cultures. Other approaches to reading books that are common in collectivist cultures have not been explored. The present study investigated the reading styles teachers (n = 40) use in naturalistic settings and compared the advantages of using individualistic versus collectivist styles related to children participation and enjoyment during book reading. The results have implications for incorporating culturally reflective approached when reading books to young children
Maternity leave, mother-child interactions, and attachment
No full textAlthough over 70% of American mothers are part of the workforce, the maternity leave policy in the United States is of twelve unpaid weeks, and only covers about half of the workforce. The amount of time a mother is able to spend with her infant before she negotiates separation and re-entry to work is expected to play a role in the way a mother learns to read her infant\u27s cues and the attachment relationship is formed. This study proposed that the length of maternity leave would affect the levels of maternal depression symtomatology, which would affect the quality of mother-child interactions, affecting infant attachment security. Data for 3,850 working mothers and their infants from the Early Childhood Longitudinal Study Birth Cohort (ECLS-B) sample were analyzed. The results of a path analysis show that controlling for SES, the length of maternity leave had a significant effect on the quality of mother-child interactions measured when infants were nine months, and that the quality of mother-child interactions mediated the relationship between the length of maternity leave and the levels of attachment security, observed when children were 24 months. Maternal depression was not found to play a significant role in the relationship between length of maternity leave and attachment security. When comparing married and single mothers, married mothers show a similar pattern to the full sample. In contrast, for single mothers, length of maternity leave was not related to the quality of mother-child interactions and attachment, yet SES predicted quality of mother-child interactions, and the quality of mother-child interactions mediated the relationship between SES and attachment security. These results have implications for the development of family policies that are sensitive to the needs of infants and mothers in the first months of life
