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
USING SELF-REGULATED STRATEGY DEVELOPMENT TO IMPROVE THE FRACTIONS SKILLS OF STUDENTS WITH AVERAGE AND LOW MATHEMATICS ACHIEVEMENT
No full textThe study investigated the effectiveness of using Self-Regulation Strategy Development (SRSD) in teaching fraction skills using an experimental research design, specifically a switching replications design. The participants consisted of 62 eighth-grade students, identified with average and low mathematics achievement, selected from a school in Al Batinah South Governorate, Oman. The participants were selected from a sample based on their mathematics achievement levels and then randomly assigned to two conditions (treatment and control group). To collect data, screening measures, a pre-post-test on fraction skills, and a social validity questionnaire were used. The results show significant differences between groups in fraction scores after receiving the intervention, indicating the effectiveness of using SRSD in teaching fraction skills. Further, the study found that SRSD is effective in helping students in the treatment group maintain fraction skills one month after intervention. The results from the self-reported questionnaire showed that the students provided positive views about how beneficial the intervention was for them. The results were discussed in terms of the role of SRSD fractions in facilitating learning for students with different levels of academic achievement and how their differences in learning environments and pre-existing differences may affect knowledge fade. Keywords: Self-regulation, fraction skills, mathematics achievement, students’ perspective
EFFECTS OF WORK EXPERIENCES ON THE POST-SCHOOL EMPLOYMENT OUTCOMES OF YOUTH WITH DISABILITIES: A STUDY OF ONE STATE VOCATIONAL REHABILITATION AGENCY’S TRANSITION PROGRAM
Get PDFThis dissertation presents information on the predictive impact of work experiences, age at time of application for vocational rehabilitation (VR) services, and priority group category of eligibility on successful VR case closure (i.e., achievement of competitive, integrated employment outcomes) for transition age youth served by one state’s VR agency. Using logistic regression, extant data were analyzed for transition age clients served by the agency over an eight-year time period, consisting of 8,966 participants. Results indicated age at time of application for VR services, priority group category, gender identification, and racial identification were each statistically significantly predictors of the ability of transition age clients to achieve a successful VR case closure. Work experience as a predictor was not found to predict outcomes. Among work experiences, Project SEARCH was the only work experience to significantly predict successful employment outcomes. Those individuals achieving higher rates of competitive, integrated employment tended to be in the less severe priority category of eligibility, older at the time of application for VR services, those who identified as male, and those who identified as White. Findings such as this inform the fields of special education and VR in considering the possible factors behind the results, examining their data further, and potentially changing their existing programs, policies, and practices or creating new ones to increase the employment outcomes of transition age clients
