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

The Effectiveness of a Combined Intervention Approach for Improving Reading Fluency in Elementary School Students
Get PDFThe ability to read plays a crucial role in the academic success and overall development of elementary school children. Unfortunately, many children in elementary school experience difficulties in reading, including issues with fluency, accuracy, and comprehension. These difficulties can lead to challenges in understanding the curriculum and result in lower academic achievement. To address this issue, a combined intervention approach was implemented, which combined repeated reading, listening while reading, error correction, and performance feedback methods. The aim of this intervention was to improve the accuracy aspect of reading fluency in elementary school children. This study used a single case experimental design with second-grade students as the research subjects. The development of children's reading abilities was measured using the Informal Reading Inventory. The results of the study indicate that the intervention provided was effective in improving the ability and fluency of reading in the research subjects.Kemampuan membaca memiliki peran yang sangat penting dalam kesuksesan akademik dan perkembangan secara keseluruhan pada anak-anak sekolah dasar. Sayangnya, banyak anak di sekolah dasar mengalami kesulitan dalam membaca, termasuk dalam hal kelancaran, akurasi, dan pemahaman bacaan. Hal ini dapat menyebabkan kesulitan dalam memahami kurikulum dan berakibat pada pencapaian akademik yang rendah. Untuk mengatasi masalah ini, diterapkan pendekatan intervensi gabungan dengan menggabungkan metode repeated reading, listening while reading, error correction, dan performance feedback. Tujuan dari intervensi ini adalah untuk meningkatkan aspek akurasi dari kelancaran membaca pada anak-anak sekolah dasar. Penelitian ini menggunakan desain eksperimen kasus tunggal dengan subjek penelitian adalah siswa kelas 2 sekolah dasar. Perkembangan kemampuan anak diukur menggunakan Informal Reading Inventory. Hasil penelitian menunjukkan bahwa intervensi yang diberikan efektif dalam meningkatkan kemampuan dan kelancaran membaca pada subjek penelitian
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
