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
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
Implementation of the 5E Model Integrated STEM-EDP to Enhance High School Students' Creative Problem-Solving Ability
Full text linkThe improvement of Creative Problem-Solving (CPS) ability in physics learning still needs to be enhanced to prepare students for the challenges of the 21st century. This study aims to determine the effectiveness of implementing the 5E model integrated with STEM-EDP on high school students' CPS ability in the topic of Renewable Energy. This research was conducted at SMA Islam Global Surya using a quasi-experimental method with a pretest-posttest control group design. The sample consisted of class X-1 as the experimental group and class X-2 as the control group. The research instrument used was essay-type questions. The implementation of the 5E model integrated with STEM-EDP was found to be effective in improving students' Creative Problem-Solving ability. This is evident from the average N-Gain score of the experimental class, which was 0.56, higher than the control class with an average N-Gain score of 0.39. Additionally, this finding is supported by the results of the Independent Sample T-Test and Paired Sample T-Test, where the obtained Sig. (2-tailed) value was 0.00 < 0.05. Furthermore, the ANCOVA test results also showed a significance value of 0.00 < 0.05. The effectiveness of implementing the 5E model integrated with STEM-EDP in enhancing high school students' CPS ability in the topic of Renewable Energy falls into the high category, as indicated by the effect size test results, with a partial eta squared (η²) value of 0.434. This improvement is based on the Constructivism Theory and Behaviorism Theory, which allows students to build new knowledge by connecting it to prior experiences through interactions involving stimulus and response during the learning process
IMPLEMENTATION OF THE PBL MODEL INTEGRATED WITH STEM-EDP TO IMPROVE NUMERACY LITERACY SKILLS IN HIGH SCHOOL STUDENTS
Full text linkThe Importance of Numeracy Literacy Skills in High School Students and the Effectiveness of the PBL Model Integrated with STEM-EDP. Numeracy literacy skills in students need to be improved, as these skills are essential in 21st-century education. This study aims to describe the effectiveness of implementing the PBL model integrated with STEM-EDP to enhance high school students' numeracy literacy skills on straight motion. The research was conducted at SMAN 13 Bandar Lampung using a quantitative experimental approach with a nonequivalent pretest-posttest control group design. The instrument used was an essay test. Learning with the PBL-STEM-EDP model has improved students' numeracy literacy skills. This is evident from the average N-gain score in the experimental class, which was 0.79, compared to 0.33 in the control class. These data indicate a significant difference in numeracy literacy skills between the experimental and control classes. This finding is supported by the results of the Independent Sample T-Test, Paired T-Test, and ANCOVA, which yielded a Sig. (2-tailed) value of 0.000 < 0.05. Thus, it can be concluded that the PBL model integrated with STEM-EDP is effective in improving students' numeracy literacy skills. Additionally, the effect size value of 0.802 indicates that the PBL-STEM-EDP model has a strong influence on enhancing students' numeracy literacy skills. Future researchers should not only observe students' initial and final abilities but also examine the learning process in more detail.Penelitian ini bertujuan untuk mendeskripsikan efektivitas implementasi model PBL terintegrasi STEM-EDP untuk meningkatkan kemampuan Literasi-Numerasi peserta didik SMA pada topik gerak lurus. Penelitian ini dilakukan di SMAN 13 Bandar Lampung, menggunakan penelitian kuantitatif eksperimen dengan desain nonequivalent pretest posttest control group design. Instrumen yang digunakan adalah soal tes uraian. Pembelajaran menggunakan model PBL STEM-EDP mampu meningkatkan kemampuan literasi numerasi peserta didik. Hal ini dapat dilihat dari rata-rata nilai N-gain pada kelas eksperimen sebesar 0,79 sedangkan kelas kontrol sebesar 0,33. Berdasarkan data tersebut menunjukan bahwa kemampuan literasi numerasi peserta didik mempunyai perbedaan yang signifikan pada kelas eksperimen dan kelas kontrol. Hal ini didukung dengan data hasil uji Independent Sample T-Test, Paired T-Test, dan ANCOVA diperoleh nilai Sig. (2-tailed) 0,000 < 0,05. Maka dapat disimpulkan bahwa model pembelajaran PBL terintegrasi STEM-EDP efektif dalam meningkatkan kemampuan literasi numerasi pada peserta didik. Adapun diketahui juga nilai effect size yaitu sebesar 0,802, maka dapat diartikan model PBL STEM-EDP memiliki pengaruh besar dalam peningkatan kemampuan literasi numerasi peserta didik.

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
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
