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
Tablets and Trees: Equipping Forestry Students with Mobile Tools for Learning In and Out of Classroom
Get PDFThis paper presents the case of how a department of applied science went about implementing a tablet initiative in a two-year diploma program. Tablets were a required tool for entry into the program with a goal of reducing textbook purchase costs for students, mirroring industry standard practices in mobile device usage, and enabling collaborative and active learning in the classroom. Based on surveys, interviews, and classroom observations we found that the integration of tablets, when explicitly positioned as a teaching and learning tool supported new forms of peer-to-peer collaboration, encouraged the use of open educational resources, and shifted traditional classroom dynamics reformulating the division of labour between faculty and students. Using activity theory as a lens for the analysis, we examine how the introduction of this tool changes the system of activity and impacts the division of labour, community, and rules both within and beyond the classroom.FacultyReviewe
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
Elements of effective instructional design for elementary mathematical problem solving computer software
No full textProblem solving is an area of mathematics needing urgent attention by educators. Mathematics organizations, researchers and curriculum strongly advocate for increased problem solving skill development in students. Computer technology may aid some students in learning or practising problem solving skills. This research investigates student perceptions of how effective are instructional design elements of mathematical software, as it relates to their development of problem solving skills.
Eighteen instructional design elements were identified from the literature on educational software design. Thirty-two grade five students from varied socio-economic backgrounds in a large district school board in Ontario, Canada, used three mathematical problem solving software programs. For each program, students recorded their perceptions of the effectiveness of each design element in solving mathematical problems, using a written questionnaire and an audiotaped interview.
The results of this study indicate that all eighteen identified instructional design elements were judged to be effective by students for learning in mathematical software programs. Students highly rated elements such as feedback, written help and audio guides, because they perceived these elements to aid in their understanding and navigation of the program, as well as provide assistance in persevering with challenging problem solving tasks. Students also felt that having attainable and realistic goals was appropriate. Results sometimes differed according to mathematical ability. For animation elements, low ability students perceived animation to aid in their learning more than high ability students. Low ability students perceived organization and tools in a software program to assist them more in their learning than did the high ability students. Gender did not have any effect on student responses. Examination of the three software programs suggests that they were developed to be gender-neutral.
This research indicates that students are aware of software design aspects which aid in their learning, and their insights can provide teachers, software developers and software reviewers with instructional design elements (e.g. narrated text written on screen, constant feedback on progress, detailed graphics, realistic goals) to consider when designing or acquiring educational software.Ph.D
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
