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
Peningkatan Hasil Belajar Matematika Materi SPLDV melalui Model Pembelajaran PSI (Personalized System Of Instruction)
Get PDFPenelitian ini merupakan penelitian tindakan kelas (classroom action research) yang bertujuan untuk meningkatkan hasil belajar matematika pada siswa kelas VIII A SMP Negeri 1 Matakali dengan jumlah 21 siswa. Penelitian ini dilakukan dalam 2 siklus, masing-masing dari 4 pertemuan termasuk tes di setiap akhir siklus. Pengambilan data dilakukan dengan menggunakan tes tertulis pada akhir setiap siklus dan pengamatan aktivitas peserta didik dilakukan setiap proses pembelajaran berlangsung. Data yang terkumpul dianalisis dengan menggunakan analisis statistik deskriptif kualitatif dan kuantitatif. Hal ini didasarkan pada hasil analisis deskriptif kuantitatif yang menunjukkan bahwa nilai rata-rata prestasi belajar matematika peserta didik pada tes awal menentukan tutor membimbing peserta didik yang belum memahami model pembelajaran sebelum PSI (Perzonalized System of Instruction) dan pada pada siklus I setelah model Pembelajaran PSI (Perzonalized System of Instruction), nilai rata-rata hasil belajar matematika yang dicapai oleh peserta didik adalah 59 sedangkan pada siklus II telah meningkat menjadi 86 dan aktivitas peserta didik mengalami peningkatan sehingga dapat disimpulkan bahwa model pembelajaran PSI (Perzonalized System of Instruction) dapat meningkatkan hasil belajar peserta didik
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
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
Pengembangan Perangkat Pembelajaran Matematika Model Kooperatif dengan Pendekatan Kombinasi Experiences, Language, Pictorial, Symbol, Application (ELPSA) dan Saintifik
Get PDFThe research was Development Research with limited test which aimed to develop Mathematics learning devices with Cooperative Model with The Combination Of Experiences, Language, Pictorial, Symbol, Application (ELPSA) and Scientific Approach in Inequality Absolute Value, Fraction, and Irrational material which covered Lesson Plan, Students Book, and Students Worksheet. The subjects of the research were the students of class X at SMAN 2 Polewali Mandar District with the total of 35 students. The Development procedure of the research employed Thiagarajan Model (4-D) which covered four stages, namely defining, design, development, and dissemination. The result of limited test showed that (1) the average score obtained by the students in learning result test is 75.42 from ideal score by 100 with deviation standard 8.69 where 29 from 35 students or 82.85% met individual completeness which shows that classical completeness had been reached; (2) by using Mathematics learning devices with Cooperative Model with the Combination Of Experiences, Language, Pictorial, Symbol, Application (ELPSA) and Scientific Approach, the students are more active in the learning process; (3) in general, the students gave good responses on the learning devices used; and (4) the level of teacher' abilities in managing learning process of Cooperative Model with the Combination Of Experiences, Language, Pictorial, Symbol, Application (ELPSA) and Scientific Approach is in good category, meaning that the teachers' performances can be maintained. Based on the results of the research, it can concluded that Mathematics learning devices with Cooperative Model with the Combination Of Experiences, Language, Pictorial, Symbol, Application (ELPSA) and Scientific Approach developed has met the requirement of valid, effective, and practical criteria
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
