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
Analisis Pemodelan Tiga Dimensi Bangunan Bersejarah Menggunakan Integrasi Data Terrestrial Laser Scanner dan Close Range Photogrammetry (Studi Kasus: Candi Gunung Gangsir, Kabupaten Pasuruan)
No full textCandi Gunung Gangsir merupakan salah satu peninggalan sejarah milik Indonesia. Keberadaan Candi Gunung Gangsir diperkirakan muncul pada abad ke-11 Masehi, bersamaan dengan berakhirnya pemerintahan dan peninggalan Kerajaan Medang Kamulan. Kerajaan ini merupakan kelanjutan dari Kerajaan Mataram Kuno di Jawa Tengah yang dipindahkan ke Jawa Timur oleh Mpu Sindok. Bangunan dengan nilai budaya dan sejarah seperti candi ini membutuhkan perlindungan serta pemeliharaan, di mana salah satu caranya adalah dengan melakukan dokumentasi dalam bentuk 3D. Pada penelitian ini Pemodelan 3D dibentuk dengan menggunakan integrasi dua metode fotogrametri, yaitu Laser Scanning dengan alat TLS (Terrestrial Laser Scanner) dan Close Range Photogrammetry dengan UAV Drone. Data yang didapat dari kedua metode ini diintegrasikan dengan software CloudCompare dan menggunakan metode Point Pairs Picking sehingga membentuk model 3D Candi Gunung Gangsir secara utuh. Hasil integrasi data antara TLS dan UAV telah berhasil dilakukan, di mana nilai RMSE pada model 3D TLS sebesar 0,007 meter dan RMSE pada model 3D UAV sebesar 0,006 meter. Lalu dilakukan integrasi dan mendapatkan nilai RMSE final sebesar 0,025 meter dengan jumlah point clouds setelah dilakukan meshing & texturing sebanyak 241.606 points. Berikutnya dilakukan uji akurasi dimensi terhadap hasil model 3D dengan data lapangan dan didapatkan nilai RMSE 0,009 meter. Uji Simple Paired t-Test digunakan untuk mengetahui bahwa terdapat korelasi antar variabel dan membuktikan bahwa tidak ada perbedaan yang signifikan antara hasil model 3D dengan bentuk asli Candi Gunung Gangsir dengan nilai significance sebesar 0,493.

Gunung Gangsir Temple is one of Indonesia's historical relics. The existence of Gunung Gangsir Temple is estimated to have appeared in the 11th century AD, along with the end of the reign and legacy of the Medang Kamulan Kingdom. This kingdom was a continuation of the Ancient Mataram Kingdom in Central Java which was moved to East Java by Mpu Sindok. Buildings with cultural and historical values such as this temple need protection and maintenance, where one way is to do documentation in 3D. In this research, 3D modeling is formed using the integration of two photogrammetric methods, namely Laser Scanning with TLS (Terrestrial Laser Scanner) and Close Range Photogrammetry with UAV Drone. The data obtained from these two methods were integrated with CloudCompare software and using the Point Pairs Picking method to form a 3D model of Gunung Gangsir Temple as a whole. The results of data integration between TLS and UAV have been successfully carried out, where the RMSE value on the TLS 3D model is 0.007 meters and the RMSE on the UAV 3D model is 0.006 meters. Then integration was carried out and obtained a final RMSE value of 0.025 meters with the number of point clouds after meshing & texturing of 241,606 points. Next, the dimensional accuracy test was carried out on the results of the 3D model with field data and obtained an RMSE value of 0.009 meters. Simple Paired t-Test is used to determine that there is a correlation between variables and prove that there is no significant difference between the results of the 3D model and the original form of Gunung Gangsir Temple with a significance value of 0.493
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
