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
Innovations in assessing students’ digital literacy skills in learning science: effective multiple choice closed-ended tests using rasch model
Get PDFThis research goal to develop a multiple-choice closed-ended test to assessing and evaluate students’ digital literacy skills. The sample in this study were students at MTsN 1 Blitar City who were selected using a purposive sampling technique. The test was also validated by experts, namely 2 Doctors of Physics and Science from Yogyakarta State University. The test instrument was developed based on five aspects of digital literacy skills: information, communication, content creation, security and problem-solving. Data have been analyzed descriptively and inferentially using the Rasch version and the assist of Quest software. The results showed that eight multiple-choice closed-ended test instruments were declared valid based on expert validation with an Aiken V value of 1.00. The reliability result is 0.97 with a very high category, and the INFIT MNSQ standard deviation value is 0.86 - 1.16, so seven items are by the Rasch model. Thus, the seven items in the multiple-choice closed-ended test instrument can be used to assessing and evaluate students’ digital literacy skills in learning science
Development and Validation of Animation-Based Science Learning Media in the STEM-PBL Model to Improve Students Critical Thinking and Digital Literacy
No full textThis study aims to produce an animation technology-based learning media product with the STEM-PBL model to improve critical thinking and digital literacy that is feasible and valid. The research uses a 4-D model. The research subjects were 27 MTsN, 1 Blitar City student, two expert lecturers, and one science teacher. The instruments used were validation sheets, readability, and practicality questionnaires with a 5-level Likert scale. The data analysis technique is descriptive and uses the ideal standard deviation value. The research results show that the product is in a very valid and feasible category, with a percentage of 94% material experts and 92% media experts. The readability and practicality tests are in a very good variety with rates of 85% and 99%. So that the product is very feasible and valid to use in learning. The recommendation for further research is to test the effectiveness of media when learning to improve student's critical thinking and digital literacy.Penelitian ini bertujuan untuk menghasilkan produk media pembelajaran berbasis teknologi animasi dengan model STEM-PBL untuk meningkatkan kemampuan berpikir kritis dan literasi digital yang layak dan valid. Penelitian ini menggunakan model 4-D. Subyek penelitian adalah 27 peserta didik MTsN 1 Kota Blitar, dua orang dosen ahli, dan satu orang guru IPA. Instrumen yang digunakan adalah lembar validasi, keterbacaan, dan angket kepraktisan dengan skala likert 5 level. Teknik analisis data bersifat deskriptif dan menggunakan nilai standar deviasi ideal. Hasil penelitian menunjukkan bahwa produk berada pada kategori sangat valid dan layak, dengan persentase ahli materi 94% dan ahli media 92%. Tes keterbacaan dan kepraktisan berada dalam variasi yang sangat baik dengan tingkat 85% dan 99%. Sehingga produk tersebut sangat layak dan valid digunakan dalam pembelajaran. Rekomendasi untuk penelitian selanjutnya adalah menguji keefektifan media dalam pembelajaran untuk meningkatkan berpikir kritis dan literasi digital siswa
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
