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
KONTRIBUSI MODEL INQUIRY TERBIMBING TERHADAP KEMAMPUAN PENALARAN MAHASISWA PROGRAM STUDI MANAJEMEN PADA MATA KULIAH MATEMATIKA EKONOMI
Get PDFThe purpose of this study was to determine the contribution of the guided inquiry learning model to the reasoning ability of students. This research is a quasi-experimental study using two groups of samples (experimental and control) that have been declared normal and homogeneous. The study was conducted at SMP Negeri 27 Medan in 8th-grade students with two classes sample, each class with 40 students. The instrument used was in the form of a reasoning ability test consisting of pretest questions (6 items) and posttests (3 items) which have been declared valid and reliable. The results showed that in the guided inquiry class, students 'reasoning ability was influenced by the KAM value of 66%, while in the expository class, students' reasoning ability was influenced by the KAM value of 71.3%. This shows that the contribution of KAM in the guided inquiry class is smaller than the contribution of KAM in the expository class on reasoning ability (66% 71.3%).
KEMAMPUAN LITERASI MATEMATIS MAHASISWA PROGRAM STUDI MANAJEMEN UNIVERSITAS PEMBANGUNAN PANCA BUDI-MEDAN
Get PDFEducational demands on a person's ability in the field of mathematics are not enough just to have the ability to count, but also to have the ability to think logically, systematically and critically in an effort to develop mathematical problem solving abilities. To be able to find a solution to a problem, it is very important for students to be able to dig up information from various sources and various forms of information and interpret it using logical, systematic, and critical mathematical thinking skills, which are then known as mathematical literacy skills. The purpose of this study was to determine the ability of mathematical literacy in management study program students at the Panca Budi Development University in Medan. This research is part of a type of qualitative research with the approach used in this study a descriptive approach with a sample of 30 students who were selected randomly. The instrument used is a test of mathematical literacy skills in basic mathematics courses. The data analysis technique used is descriptive analysis of the data collected. Based on the research results obtained, it can be concluded that the mathematical literacy skills of the management study program students at the Panca Budi Brada Development University are in the sufficient category with the dominant mathematical literacy ability being at a moderate level with a percentage of 43.34%

Adapun tujuan penelitian ini adalah untuk mengetahui peningkatan kemampuan pemecahan masalah siswa dilihat dari capaian pembelajaran siswa. Penelitian ini merupakan penelitian tindakan kelas yang dilaksanakan di SMP Islam Al-Ullum Terpadu, Medan. Pembelajaran dilaksanakan untuk mengajarkan materi dasar aljabar pada siswa kelas VII yang berjumlah 38 orang siswa. Instrumen yang digunakan adalah tes dan non-tes. Tes yang digunakan berbentuk uraian sebanyak 5 butir soal yang mengacu pada kemampuan siswa dalam pemecahan masalah. Sedangkan instrumen non tes digunakan untuk mengamati aktivitas yang terjadi selama proses pembelajaran di kelas. Siswa dinyatakan tuntas secara individu apabila memperoleh nilai lebih dari 75 dengan kriteria ketuntasan belajar minimal 75% dari total siswa. Disimpulkan bahwa pendekatan matematika realistik dapat meningkatkan kemampuan pemecahan masalah pada saat siklus II yang dilihat dari rata-rata kemampuan siswa di kelas, yaitu dari 72,474 menjadi 76,895; persentase ketuntasan belajar klasikal siswa, yaitu dari 52,63% menjadi 78,95%; demikian pula yang terjadi jika dilihat dari aspek ketuntasan siswa dalam menerapkan prosedur penyelesaian masalah, yaitu dengan rata-rata persentase peningkatan sebesar 8,553.Kata Kunci: pendekatan matematika realistik, kemampuan siswa, pemecahan masalah. Abstract. One of the biggest problems in modern mathematics learning is the practice of teachers in presenting mathematics in the form of finished products, ready-made, abstract and mechanistic teaching. The purpose of this research is to determine the enhancement of student problem-solving skills seen from student learning access. This research is a class action research conducted in the integrated Al-Ullum Islamic Junior high School, Medan. They were learning conducted to teach the primary algebraic material in class VII students that are 38 students. The instruments used are test and non-test. The test used is a description of 5 rounds of questions that refer to the ability of students in problem-solving. Non-test instruments used to observe activities that occur during the learning process in the classroom. The student completed learning when obtaining a value of more than 75 with a minimum learning criteria of 75% of the total students. It concluded that the realistic mathematical approach could improve problem-solving skills during the II cycle seen from the average student's ability in the class, i.e. from 72.474 to 76.895; Percentage of the student's classical learning, which is from 52.63% to 78.95%; Similarly, if viewed from the student's submission aspect in implementing a problem-solving procedure, that is with an average percentage increase of 8.553.Keywords: realistic mathematical approaches, student skills, problem-solving
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
