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
THE EFFECTIVENESS OF USING AUTHENTIC MATERIALS ON TEACHING SPEAKING FOR ELEVENTH GRADE STUDENTS’ OF ISLAMIC HIGH SCHOOL STUDENTS OF MU’ALLIMIN MUHAMMADIYAH YOGYAKARTA IN ACADEMIC YEAR 2013/2014
Full text linkThe objectives of this research is to find out whether the using authentic materials on teaching speaking is effective for eleventh grade students of Islamic High School of Mu’allimin Muhammadiyah Yogyakartain academic year 2013/2014 and whether there is any significance difference between students’ speaking ability taught by using authentic materials and thestudents’ speaking who taught by using created materials. This research is experimental research. The participants of the research were the eleventh grade students of Islamic High School of Mu’allimin Muhammadiyah Yogyakartain academic year 2013/2014. The research instrument used by the researcher was speaking test. The data in the research were mainly gathered through the use of pre-test and post-test. After the data were collected, the writer analyzed them. The researcher used SPSS16.0 to analyze the students’ speaking ability between the experimental group and the control group after the authentic materials was applied. Seeing from the finding of the research, it shows that there is a difference scores got by the students in theexperimental group and in the control group after the authentic material was applied. In the pre-test result, the mean of the experimental group was 58.85 and 58.94 for the control group. In post-test, after the authentic material was applied, the mean of the experimental group became 73.94 and 63.15 for the control group. It can be seen that the mean of the experimental group was higher than the control group in post-test. Seeing from the comparison of mean between the experimental group and the control group, it can be known that teaching speaking by using authentic material is effective. In order to find the answer of the hypothesis, certain statistics was used. The analysis of hypothesis testing was conducted using ANCOVA. From the computation, it was known that the significance of value was 0.029 < 0.05, then the null hypothesis (Ho) is rejected. Therefore, the hypothesis shows that there is a significance difference between students taught using authentic material and those taught without using created material is accepte
Analisis Software Hybrid Untuk Deteksi Gejala Penyakit
Full text linkPenelitian ini dilakukan untuk melihat kecendrungan penyakit yang ditimbulkan akibat pola hidup yang tidak sehat pada masyarakat tertinggal dan pesisir desa-desa sekitar kabupaten Gresik dan Tuban dengan menggunakan algoritma hybrid melalui konstruksi struktur Bayesian Network. Masalah yang akan diselesaikan pada penelitian ini adalah belum ada system yang mampu mendeteksi hubungan antara perilaku hidup tidak sehat dengan penyakit yang di timbulkan. Model struktur ini belum pernah diaplikasikan secara langsung di lapangan untuk mendeteksi suatu kejadian sebab akibat misalnya jika suatu perilaku itu tidak sehat maka akan timbul suatu penyakit. Pengaplikasian model ini perlu dilakukan dengan suatu studi lapangan untuk mengetahui dan membuktikan manfaat yang sebenarnya dari konsep konstruksi struktur hybrid bayesian network. Tujuan dari penelitian ini adalah menghasilkan model perangkat lunak yang mampu mendeteksi dini kecenderungan resiko penyakit masyarakat desa tertinggal dan pesisir yang memiliki pola hidup tidak sehat dalam bentuk konstruksi struktur dan menghasilkan probabilitas nilai dengan cendrungan penyakit. Hasil perbandingan antara struktur asal dengan struktur hasil uji coba menunjukan tingkat kecocokan untuk data uji lengkap selisih 10% dengan struktur aslinya, dan tingkat kecocokan untuk data uji tidak lengkap sebesar lebih dari 20% tergantung jumlah missing value nya. Validitas bahwa orang merokok akan mengalami kecendrungan punya penyakit Tuberculosis, Bronkitis atau Lung cancer melalui uji system adalah 80% sampai 90%
