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
Look-Say-Cover-Write-Say-Check and Old Way/New Way - Mediational Learning: A Comparison of the Effectiveness of Two Tutoring Programs for Children with Persistent Spelling Difficulties
Full text linkThe goal of this research was to compare the effectiveness of the Look-Say-Cover-Write-Say-Check and Old Way/New Way Mediational Learning approaches to spelling remediation. Prior to commencing the research program, selected third and fourth year Bachelor of Education (Primary) pre-service teachers were trained by the first author in tutoring methods in both spelling remediation approaches. Participants consisted of 25 students, ages 7-12, from local community schools, who were randomly allocated to one of the two treatment conditions. The program involved one-on-one tutoring by the trained pre-service teachers, under the mentorship of the first author. Statistical analysis of the pre- and post-test results indicated significant improvement for both groups, but one method did not emerge as superior to the other
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
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
Factors that Influence the Desire to Become Teachers of Technology: An Australian Study
Full text linkIn this study, 337 pre-service teachers enrolled in Technology Teacher Education Programs (TTEP), in eight tertiary institutions across Australia, responded to a questionnaire seeking information about those factors that influenced their decision to become teachers of Technical and Applied Studies (TAS). The study found: a majority of the respondents were male (71%); most came from urban areas (61%); just over half (51%) entered the course from the workforce and just over a third of the respondents entered the course direct from school. Of the 172 respondents who came from the work force, a total of 93 (86 male) had prior trade experience. Factor analysis of attitudinal items set against a four-point Likert scale produced three factors related to their decision to become TAS teachers. These included encouragement from members of the community, the influence of experiences in technology at school, and a desire to teach. A three stage regression model was created with the scale ‘Desire to Teach’ as the ultimate dependent variable. Factors most strongly influencing ‘Desire to Teach’ included hobbies and interests prior to enrolment, encouragement from members of the community and the influence of experiences in technology at school. The authors propose a number of strategies for promoting technology teaching and increasing the TTEP student intake, based on their findings
