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
Penerapan Model Kooperatif Tipe Tps Untuk Meningkatkan Kepercayaan Diri Siswa dan Kemampuan Komunikasi Matematis di SMPN 5 Percut Sei Tuan
Get PDFThe objective of this research is to investigate the potential impact of implementing the TPS cooperative learning model on enhancing the self-confidence and mathematics communication abilities of seventh-grade students at SMP Negeri 5 Percut Sei Tuan. The specific focus will be on the Set content. This study used a class action research design, consisting of two distinct cycles. Each iteration comprises two meetings. The participants in this research consisted of 28 students from class VII-8 of SMP Negeri 5 Percut Sei Tuan. The primary focus of this study is to enhance students' self-confidence and mathematical communication abilities by using the TPS cooperative learning model on Set material at SMP Negeri 5 Percut Sei Tuan during the academic year 2022/2023. Based on the findings derived from the analysis of the data, it was observed that the mean score for students' initial self-confidence was 53.61. Additionally, the mean test score for students' initial communication skills was found to be 44.92. Among the participants, a total of 3 students (13.04%) demonstrated mastery in this area, while the remaining 20 students (86.95%) had not yet achieved mastery. The learning process in cycle I was conducted using the TPS model. As a result, the average score of student confidence increased to 62.14, while the average score of the mathematical communication ability test increased to 55.80. Out of the total number of students, 8 students (34.78%) reached the completion criteria, while 15 students (65.21%) did not reach the completion criteria. In the second cycle, there was an observed increase in student performance. The average score for student confidence was recorded as 76.29, while the average score for the mathematical communication ability test was 75.97. Out of the total number of students, 19 students (82.60%) achieved completeness in the test, while 4 students (17.40%) did not reach completeness. The self-confidence questionnaire and mathematical communication skills exam administered in cycle II yielded results indicating a satisfactory level of student proficiency. 
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
Penerapan Model Problem Based Learning untuk Meningkatkan Kemampuan Pemecahan Masalah Matematis Siswa di Kelas VIII – A SMP Negeri 1 Stabat
Get PDFThis study aims to determine whether applying the Problem Based Learning model can improve the mathematical problem solving ability of students of class VIII-A SMP Negeri 1 Stabat on SPLDV. This research is a class action research conducted in two cycles. Each cycle consists of 2 meetings. The subjects in this study were students of class VIII-A SMP Negeri 1 Stabat totalling 30 students. The object of this research is the improvement of students' mathematical problem solving ability through the application of the Problem Based Learning learning model on SPLDV material at SMP Negeri 1 Stabat in the 2023/2024 school year. Based on the results of data analysis, the average initial test score was 47.11 with the number of students who reached mastery as many as 4 students (13.33%) and students who had not reached mastery as many as 26 students (86.67%). Then learning was carried out with the Problem Based Learning learning model in cycle I and there was an increase in the problem solving ability test with an average value of 63.44 with 19 students or as many as (63.33%). Then students who have not reached completeness are 11 students or as many as (36.67%). Then in cycle II there was an increase with the average value of the student problem solving ability test being 84.11, with a total completeness of 26 students or as many as (86.67%) and the number of students who had not reached completeness was 4 students or as many as (13.33%). The level of student completeness of the problem solving ability test given in cycle II reached the good category, therefore it can be said that learning has been achieved. Thus it can be said that the class has reached more than 85% of students who have been completed to solve problems. So it can be concluded that using the Problem Based Learning model can improve students' mathematical problem solving skills

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
