Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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 Faktor-Faktor yang Mempengaruhi Ketahanan Hidup Pasien Tuberculosis dengan Model Regresi Cox (Studi kasus : Rumah Sakit Paru Bogor)
Ketahanan hidup penderita tuberculosis dipengaruhi oleh faktor eksternal maupun internal. Beberapa faktor yang dapat mempengaruhi ketahanan hidup seorang penderita tuberculosis diantaranya yaitu usia, jenis kelamin, tingkat pendidikan, sanitasi lingkungan, kebiasaan merokok dan pencahyaan rumah. Analisis survival dapat menganalisis ketahanan hidup seorang penderita penyakit. Dalam mengetahui faktor-faktor yang mempengaruhi ketahanan hidup penderita tuberculosis menggunakan analisis survival dengan model regresi cox. Adapun hasil dari analisis survival untuk ketahanan hidup pasien yaitu faktor sanitasi lingkungan, kebiasaan merokok dan mempunyai pencahayaan rumah mempengaruhi ketahanan hidup penderita tuberculosis. Data waktu survival berdistribusi 3-parameter weibull dengan parameter , , dan masing-masing bernilai 1.36794, 8.48634 dan -0.05489. Hasil dari model regresi cox menunjukkan sanitasi lingkungan menjadi faktor yang paling mempengaruhi terhadap ketahanan hidup penderita tuberculosis Penderita dengan sanitasi lingkungan kurang baik akan meningkatkan fungsi hazard sebesar e1.237. Nilai Hazard ratio sanitasi sebesar 1/1.237 atau 0.8084 menunjukkan bahwa risiko untuk sembuh penderita yang memiliki sanitasi kurang baik adalah 0.8084 kali dari penderita dengan sanitasi lingkungan yang baik
Pengembangan Model Matematika Dinamika Perokok Di Kota Bogor
Masih tingginya kasus perokok di Kota Bogor menjadi alasan bagi masyarakat, praktisi kesehatan, pemerintah untuk mengambil langkah dan kebijakan yang tepat dalam mencegah meluasnya perokok di Kota Bogor. Sebagai salah satu bidang ilmu, matematika turut memberikan peranan penting dalam mencegah meluasnya perokok yaitu melalui model matematika terkait peningkatan jumlah perokok. Pada model matematika dinamika perokok, individu dalam populasi (N) dibagi ke dalam empat kelompok yaitu kelompok perokok potensial (P), kelompok perokok kadang-kadang (L), kelompok perokok berat (S), dan kelompok mantan perokok (Q). Model matematika dinamika perokok dikembangkan dengan melibatkan faktor efikasi diri untuk berhenti merokok, sehingga model matematika yang terbentuk tersebut diharapkan dapat lebih mendekati keadaan nyata dinamika perokok di Kota Bogor, langkah selanjutnya model matematika tersebut dianalisis secara analitik dan numerik. Berdasarkan hasil yang diperoleh bahwa pada kondisi bebas perokok, jumlah perokok kadang-kadang akan mendekati nol pada 16 tahun yang akan datang dan pada kondisi marak perokok, jumlah perokok berat terus meningkat dari tahun ke tahun. Hal ini menunjukkan bahwa setelah adanya faktor efikasi diri untuk berhenti merokok jumlah perokok di Kota Bogor mengalami penurunan tetapi tidak akan mencapai nol
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We 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
