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
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
IMPLEMENTATION OF GENETIC ALGORITHM BASED ON JAVASCRIPT IN OBJECT ROUTING SHORTEST TOUR ON TIMOR ISLAND
Full text linkThe purpose of this study is to apply a genetic algorithm using a programming language that can be used to determine the shortest route to tourist attractions in Timor Island, East Nusa Tenggara. The application of genetic algorithms expected to be able to obtain the shortest route information that is most effective, the route that do not take a long time for tourists, and the presentation of route information for tourists. The method used is genetic algorithm to build the shortest route system for tourist attractions in Timor Island. The results of the system application shown that the optimization of travel routes that have been built can provide convenience in choosing tourist travel routes in Timor Island. Route optimization can help the process of making routes from the first location of departure and the attractions to be visited. The system is also used to assist domestic tourists in getting to know the attractions of Timor Island for solutions the shortest route
THE COVID-19 PANDEMIC ERA: THE EFFECTIVENESS OF GOOGLE CLASSROOM MEDIA IN DISCRETE MATHEMATICS LEARNING IN TERMS OF STUDENT LEARNING OUTCOMES
Full text linkOne of the learning media in the network that is often used in addressing various learning problems during the Covid-19 pandemic is the use of google classroom media. The purpose of this study is to find out the effectiveness of google classroom media in discrete mathematics learning in terms of learning outcomes. The type of research conducted is quasi experiment research to see the consequences of a treatment by comparing the learning outcomes of two class groups (independent class) or two time groups with the same class (dependent class). The research design is applied using one group pretest-posttest design. The samples in this study were all the fourth semester class A students who took discrete mathematics courses at the S1 level of the Mathematics Education Study Program of the Faculty of Education, Timor University which consisted of 40 students. Sample data was processed with descriptive analysis and average difference test using paired sample t test and N-Gain Score. The research results showed that learning outcomes by using google classroom media is quite effective based the students’ test results. The students’ learning outcomes after learning by applying google classroom media were higher than students’ learning outcomes before learning by applying google classroom media
Pengaruh Model Pembelajaran Cooperative Tipe Group Investigation Berbantuan Media Gambar terhadap Prestasi Belajar Siswa Kelas VIII SMP Negeri 3 Soe
Full text linkProses pembelajaran di SMP Negeri 3 Soe, masih menerapkan pembelajaran yang bersifat teacher center, serta kurangnya fasilitas belajar IPA. Hasil 75% siswa belum mencapai KKM (kriteria ketuntasan minimum), maka dari itu dilakukan penelitian tentang pengaruh model pembelajaran Group Investigation (GI) berbantuan media gambar terhadap prestasi belajar siswa. Penelitian ini mengambil sampel kelas VIII1 sebagai kelas kontrol, dan kelas VIII2 sebagai kelas eksperimen. Sebelum diberikan model GI pada kelas eksperimen dilakukan uji kesamaan rata-rata untuk mengetahui kemampuan awal kedua sampel tersebut. Hasil kesamaan uji rata-rata berdasarkan analisis SPSS, menggunakan independen sample t-test menunjukan nilai signifikan 0,45>0.05 dan uji homogenitas menunjukan bahwa 0,847>0.05 yang berarti sebaran data antara dua kelompok sampel sama secara statistik. Dengan demikian, kedua kelas tersebut dapat dilaksanakan penelitian dengan penerapan model GI pada kelas eksperimen. Teknik analisis data yang digunakan dalam penelitian ini adalah one sample t-test untuk mengetahui ketuntasan belajar siswa. Independen sample t-test untuk mengetahui rata-rata prestasi siswa pada kelas eksperimen apabila dibandingkan kelas kontrol. Paired sample t-test untuk mengetahui peningkatan prestasi belajar siswa setelah diberikan model GI. Uji regresi untuk mengetahui pengaruh model GI terhadap peningkatan prestasi belajar siswa. Hasil penelitian menunjukan bahwa hasil uji ketuntasan menunjukan nilai t-hitung 14.877> t tabel 1.76131. diketahui juga, bahwa uji ketuntasan individual menunjukan nilai sig 0.000<0.005 sehingga hipotesis diterima. Artinya rata-rata prestasi siswa melampaui KKM yang ditetapkan yaitu 70. Hasil uji peningkatan rata-rata prestasi kelas eksperimen menunjukan Nilai sig < 0,05 sehingga ada perbedaan antara kelas control dan kelas eksperimen yakni (52,58) dan sesudah perlakuan (86,55)
