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
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
Improving student’s marine literacy and science process skills through STEM-based discovery learning
No full textTo bring out science process skills and marine literacy, a learning model that is oriented towards an integrated scientific approach is needed, namely the STEM-based discovery learning model. The purpose of this study is to improve marine literacy skills and science process skills through the STEM-based discovery learning model. The study was conducted from September 2023 to January 2025 at Islamic Senior High School (MAN) 2 of Indramayu. The study was conducted in the even semester of 2023/2024. The study\u27s population was the science department, with 64 students in class X who studied the ecosystem material. The instruments used were essay questions, performance assessments, and STEM-based discovery implementation assessments. The data was analyzed descriptively and quantitatively, and using the MANOVA test. The results of the study on marine literacy skills and science process skills had significant differences between the groups tested. The application of the STEM-based discovery learning model in this study had a significant effect. The findings in this study make learning activities more active because they integrate STEM. The investigation process to obtain knowledge based on the field is included in constructivism. Students not only listen to the teacher\u27s explanation but are involved in problem-solving and investigation activities
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
Development of Problem Based Eco-website Media on the Topics of Ecosystem to Improve Critical Thinking and Problem Solving Skills
Full text linkLearning activities that can be applied to students are by providing innovative learning media so that students are encouraged to hone critical thinking skills and problem solving skills. The purpose of this research is to develop PBL based eco-website media on ecosystem material and analyze the improvement of critical thinking and problem solving skills of class X students of SMAN 1 Waringinkurung Serang district. The research method used is educational design research (EDR) using the Hannafin and Peck model which includes three stages. The need assessment stage shows that students need interesting media equipped with the presentation of images, videos, games, there are cases and media can be used anytime and anywhere without burdening smartphone memory. The design stage is carried out product design to produce eco-website media by providing learning material features in the form of images, text, and videos. Cases are available and equipped with activities with the PBL approach, and interesting games are available. The development and implement stage produces PBL based eco-website media that is feasible to use, this is indicated by the acquisition of values given by media and material experts of 88.33% and 89.17%. The results of the small group readability test to students and educators obtained results of 91,80% and 95.83%, so the media is feasible to use in learning biology ecosystem material. The results of the implementation of learning using PBL based eco-website media in the experimental class were analyzed by MANOVA test which proved that PBL based eco-website media used in biology learning can improve students' critical thinking and problem solving skills on ecosystem material. Thus, the media developed, namely PBL based eco-website, is feasible to use and can improve students' critical thinking and problem solving skills on ecosystem material. Keywords: critical thinking, eco-website, ecosystem, hannafin and peck, manova, problem solving.
