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
HUBUNGAN ANTARA PERILAKU PENGEMUDI SEPEDA MOTOR PADA BERBAGAI KEADAAN LALU LINTAS JALAN DENGAN KARAKTERISTIK PENGEMUDI, KENDARAAN, DAN PERJALANAN
Full text linkAbstrak Keberadaan sepeda motor dalam jumlah yang sangat besar di jalan menyebabkan operasi lalu lintas yang rumit dan cenderung berbahaya. Untuk memahami potensi bahaya ini dilakukan wawancara terhadap 75 responden yang terdiri dari 50 mahasiswa dan 25 dosen/karyawan Fakultas Teknik Universitas Tarumanagara. Wawancara dilakukan dengan menggunakan kuesioner. Kelompok pertanyaan pertama melipui data umum, data pekerjaan, data kesehatan, data kendaraan dan data penggunaan kendaraan responden. Kelompok pertanyaan ke dua meliputi perilaku responden pada berbagai situasi lalu-lintas. Analisis tabulasi silang dan Kendall’s tau-b dilakukan untuk mengetahui hubungan antara data kelompok pertama dengan data kelompok ke dua. Analisis Kendall’s tau-b dipilih karena teknik ini cocok untuk data yang berasal dari variabel ordinal yang mendominasi basis data untuk penelitian ini.Secara umum, pengemudi yang lebih tua cenderung lebih berhati-hati dalam bersepeda motor. Makin tua responden, makin kerap yang bersangkutan memeriksa kendaraan sebelum digunakan, makin jarang melanggar lampu merah, melewati garis henti saat menunggu lampu hijau, berkecepatan sangat tinggi, mendahului secara zig-zag, memotong dari kiri ke kanan, menggunakan jalan pada arah yang berkebalikan dari yang diizinkan, mengalami kecelakaan, menggunakan telpon seluler saat mengemudi.Kata-kata kunci: Karakteristik pengemudi sepeda motor, perilaku, situasi lalu-lintas, Kendall’s tau-
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
TINGKAT KETAATAN PENGEMUDI SEPEDA MOTOR DALAM PENGGUNAAN LAJUR JALAN PADA BERBAGAI KONDISI ARUS LALULINTAS
Full text linkAbstract A rapid increase of motorcycle ownership in the last twenty years made a decline to the road safety. This condition led Jakarta government to announce a policy for motorcycles to ride on leftmost lane on the road effectively by January 2007. Therefore, this paper analyzes the obedient of motorcyclist to the policy after about 4 months officially announced in various traffic conditions. This paper analysis is based on the 24 hours observation on both directions of Letjen. S. Parman Arterial Road using video recorder. First of all the distribution of motorcycles across the lanes are analyzed. Furthermore, the percentages of motorcycle in the leftmost lane on different time periods and different V/Cs are compared using t-test. Additionally a Pearson correlation analysis is also conducted between the percentage of motorcycle in the leftmost lane and several other variables. The results shows about 46 percent of motorcyclists obey the policy. The analysis also shows that there are significant differences between the obedience of motorcyclists in the 10.00-16.00 observation periods and in the 22.00-06.00 observation period.Keywords : lane distribution, motorcycle, Jakart
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
