Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
Klasik test kuramı’na ve madde tepki kuramı’na dayalı test eşitleme yöntemlerinin karşılaştırılması
No full textThis study aims to choose the equating method with the least equating error by using the equating methods in Classical Test Theory and Item Response Theory. In this study, booklet 1 and booklet 3 data were used for PISA (Programme for International Student Assessment) 2012 Mathematics test. Data from Turkey, Indonesia, Shanghai/China and Finland, countries participating in PISA 2012, were selected for this study. Non-equivalent groups design was used in the test equating process. Linear equating methods [Tucker (w1=1, w1=0.5), Levine observed score (w1=1, w1=0.5), Levine true score, Classical Congeneric and Braun-Holland), equipercentile equating methods (pre smoothing according to C6 polynomial degree, beta4, post smoothing according to S 0.05 cubic function, frequency estimation (w1=1, w1=0.5) ] were used in the study. In Classical Test Theory, the least error is obtained from the frequency estimation method with a synthetic universe weight of w1 = 0.5. For the Item Response Theory, the calibration method was first decided, which is the Stocking-Lord method. After the scale transformation was achieved with the Stocking-Lord calibration method, the equating scores were calculated from the IRT's true and observed equating methods. The least error in IRT was obtained from the true score equating method. For error values, error coefficients were calculated according to Newton-Raphson's delta method and bootstrap methods. When the error coefficients (delta and bootstrap) of the equating methods in both theories were compared, it was found that the equating methods based on IRT had fewer errors than the equating methods in CTT, and the method with the least equating error was the IRT true score equating. The least equating error frequency estimation in CTT (w1=0.5) and the most error Levine true score equating method.Bu çalışmanın amacı Klasik Test Kuramı (KTK) ve Madde Tepki Kuramı (MTK) bünyesindeki eşitleme yöntemlerini kullanarak en az eşitleme hatasına sahip eşitleme yöntemine karar vermektir. Bu çalışmada PISA 2012 Matematik testi için kitapçık 1 ve kitapçık 3 verileri kullanılmıştır. Bu çalışma için PISA (Uluslararası Öğrenci Değerlendirme Programı) 2012 uygulamasına katılan Türkiye Endonezya, Şangay/ Çin ve Finlandiya ülkelerin verileri seçilmiştir. Test eşitleme sürecinde eşdeğer olmayan gruplar deseni kullanılmıştır. Araştırmada ele alınan KTK’da doğrusal eşitleme yöntemleri [Tucker (w1=1, w1=0.5), Levine gözlenen puan (w1=1, w1=0.5), Levine gerçek puan, klasik konjenerik ve Braun-Holland], eşit yüzdelikli eşitleme yöntemleri [C6 polinomial derecesine göre ön düzgünleştirme, beta4 , S 0.05 kübik fonksiyona göre son düzgünleştirme, frekans kestirim (w1=1, w1=0.5)] kullanılmıştır. Klasik Test Kuramında en az hata w1=0.5 sentetik evren ağırlığıyla Frekans kestirim yönteminden elde edilmiştir. MTK için öncelikle kalibrasyon yöntemine karar verilmiş ve bu yöntem Stocking-Lord yöntemidir. Stocking-Lord kalibrasyon yöntemi ile ölçek dönüşümü sağlandıktan sonra MTK’daki gerçek ve gözlenen eşitleme yöntemlerinden eşitlenmiş puanlar hesaplanmıştır. MTK’daki en az hata gerçek puan eşitleme yönteminden elde edilmiştir. Hata değerleri için NewtonRaphson’un delta yöntemi ve boostrap yöntemlerine göre hata katsayıları hesaplanmıştır. Her iki kuramdaki eşitleme yöntemlerinin hata katsayıları (delta ve boostrap) karşılaştırıldığında MTK’ya dayalı eşitleme yöntemlerinin KTK’daki eşitleme yöntemlerinden daha az hataya sahip olduğu ve en az eşitleme hatasına sahip olan yöntemin MTK gerçek puan eşitleme olduğu bulunmuştur. KTK’da en az eşitleme hatası frekans kestirim (w1=0.5) ve en fazla hata Levine gerçek puan eşitleme yöntemidir
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
Turkish adaptation of behavioral regulations in sports questionnaire and reviewing psychometry properties: Validation and reliability study
Get PDFPurpose of this study is to adapt Behavioral Regulation in Sports Questionnaire (BRSQ) which developed by Lonsdale, Hodge and Rose (2008) in Turkish and review psychometry properties. The scale consists of 24 items and 6 subdimension including intrinsic motivation, integrated regulation, identified regulation, introjected regulation, external regulation and motivation. Study group consists of total 681 student-athlete whom are licensed athletes and study at Physical Education and Sports College of Ahi Evran University, Erciyes University, Dumlupinar University and Çanakkale 18 Mart University. In order to determine psychometry properties of scale internal consistency, material and factor analysis and test-retest methods were applied. Cronbach alpha internal consistency coefficient of the measurement determined as follows; 0.790 for total points, 0.856 for intrinsic motivation subdimension, 0.838 for integrated regulation subdimension, 0.862 for identified regulation subdimension, 0.740 for introjected regulation subdimension, 0.788 for external regulation subdimension and 0.800 for motivation subdimension. In the analyzes performed, the data obtained from the exploratory and confirmatory factor analysis confirmed the 6-factor structure of the scale. In addition, scale-based analyzes yielded high test-retest scores. In this sense, it is considered that the scale is a valid and reliable measurement tool for the Turkish sample group. © 2018, Sciedu Press. All rights reserved
