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
Problematising problematisation: insights from critical pedagogy in a writing lesson in Bangladesh
No full textProblematisation is the means by which critical pedagogy attempts to destabilise power relations related to gender, race, class, identity etc. Studies in critical pedagogy in language teaching explore different ways of problematisation treating problematisation as classroom practice. However, they do not specifically address the teacher’s struggle in employing problematisation and the learners’ experience with it in classroom settings. Hence the complexity of problematisation remains neglected in research in critical pedagogy in classroom contexts. This article explores the notion of problematisation through an analysis of a writing lesson involving undergraduate students in Bangladesh. It analyses both the teacher’s and a student’s encounters with and reflections on problematisation throughout the lesson, and reveals that problematisation embodies complexities, and is empowering when it is self-reflexive
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
Bangladeshi Young Children’s Smartphone Use: Status and Parents’ Awareness
Full text linkNowadays the tendency for smartphone use among children is noticeable and day by day this tendency is increasing at an alarming rate. The aim of this study was to explore the status of Bangladeshi young children’s smartphone use and parents’ awareness of young children’s smartphone uses in terms of the American Academy of Paediatrics (AAP) guidelines. The study employed a mixed-methods research approach and adopted purposive sampling. The data were collected through an online mixed questionnaire from 83 parents who owned smartphones and whose children were between 0 and 5 years old. The findings show that 44% of children spent more than 1 hour on the smartphone screen which is higher than the screen time recommended by the AAP guidelines. It was found that 65% parents gave their children smartphones to entertain them, while 62.3% for learning purposes, 42.9% for keeping their children calm, 37.7% for feeding their children, and 23.4% for keeping their children busy during their work. It is noteworthy that 78% parents found different kinds of developmental problems in their children, while the rest 22% found no negative effects on their children. The study reveals a significant gap in parental awareness and knowledge regarding the AAP guidelines on children’s screen use. The results show that 75.6% of parents did not know about the guidelines for children’s screen use recommended by the AAP. Although they did not know the recommended guidelines, 81.1% of the parents had taken various steps to control their children’s excessive smartphone usage and the steps were effective in reducing children’s excessive smartphone use. As most of the parents were found unaware of the AAP guidelines for screen use, there is a need for increasing proper awareness among parents to mitigate the negative effects of children’s smartphone use.
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
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
