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
Penerapan Pembelajaran Biologi Model Problem Based Instruction Scientific untuk Meningkatkan Motivasi Belajar Siswa SMP
Full text linkBiologi merupakan salah satu mata pelajaran ilmu alam yang berhubungan dengan kehidupan sehari hari. Pembelajaran biologi tergolong ke dalam IPA di Sekolah Menengah Pertama. Namun, masih ada pembelajaran yang masih didominasi oleh guru, kurang efektifnya pembelajaran, suasana kelas yang kurang hidup sehingga kurang mendorong siswa untuk belajar. Penelitian ini bertujuan untuk mengetahui pembelajaran bioologi dengan PBI dapat meningkatkan motivasi belajar siswa SMP. Subyek penelitian adalah siswa kelas VIIA SMP N 1 Indramayu. Jenis penelitian merupakan deskripsi kualitatif yang dilakukan sebanyak 2 siklus. Instrumen penelitian yaitu lembar keterlaksanaan PBI, Lembar obserservasi motivasi belajar siswa. Hasil penelitian didapatkan bebeberapa catatan observer dari keterlaksanaan PBI. Motivasi belajar siswa meningkat dari siklus sebelumnya dan lebih baik dari pembelajaran sebelum diberikan tindakan kelas
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
PENGGUNAAN MODEL GROUP INVESTIGATION UNTUK MENINGKATKAN BERPIKIR KRITIS SISWA SMP
Full text linkGroup Investigation model is one of cooperatif metode that can grows critical student from directly experience. Based on observation in fSMP 1 Indramayu 2016 were 40% the group was less colaboration, 60% evidences was less, 65% students weren’t connected problems each other, 55% decision hadn’t most alternative problem solving to be collected. This aim research to descript critical thingking used group investigation model. Research metode qualititave descriptive, Research parameter is critical skill student and these indicator were problem indentifiy, argument analize, definition, finding source, observasion and result, mind based consideration ability integration to defend decision. Instrument research was quisioner. Result study from quisioner were 78% was good, 71% was enough. Conclusion was critical thinking skill can be used in group investigation model
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
Analysis of Learning Enthusiasm Evaluation Through Group Investigation in Learning Quality
Full text linkThe Group Investigation model is a cooperative model to develop an enthusiasm for learning. Problems in the field from interviews with students of SMP 1 Indramayu were found to be as follows: lack of group collaboration, less responsiveness, lack of attention, sleepiness so that it can be concluded that there is a lack of enthusiasm for students in learning. The purpose of this research is to analyze the indicators of the most dominant learning enthusiasm if learning is carried out through Group Investigation to solve problems in the places observed. The research method is descriptive qualitative analysis. A questionnaire instrument measured the four indicators. The subject of the research is class VIII Middle School 1 Indramayu. Data collection techniques are data collection, data presentation, conclusions. The results show that from the four indicators of enthusiasm, the indicator that got the highest percentage (83%) was students' enthusiasm in noting important things as teaching materials at home. The conclusion of the enthusiasm indicator in the form of student learning enthusiasm in recording important things is the most dominant when learning is implemented through Group Investigation. Thus, it is necessary to improve learning through group discussions in the future
