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
PERANCANGAN UNTUK MENENTUKAN SETING PARAMETER OPTIMUM PADA PROSES PEMBUATAN PRODUK ROLL
Get PDFDesign of Experiment (DOE) is the design of any information gathering exercise where variation is
preset, whether under the full control at the experiment or not. Problem faced by Atmaja Jaya Industry, Klaten is how to produce high quality product with a minimal amount of defective products. Therefore, this study will look at factor that affect the quality of roll 6” TL in order to obtain the best level setting in the production process. This study uses experimental design with the Taguchi method. Factors to be tested in this study is long making liquid metal (factor A), the old foundry (factor B), and total time of casting (factor C). Each factor has three levels so that the use of orthogonal array L9
. From the result of pooling up mean, the best level combination of factors that affect the quality of roll 6”TL is the length of manufacture of liquid metal which set at 100 minutes, the old foundry is set at 5 seconds and the total time of casting that set in 14 minutes. While the result of pooling up SN ratio for the best level combination of factors that affect the quality of production process variants roll 6 “TL which the length of the manufacture of liquid is set at 100 minutes and total time of casing that are set in 14 minutes
Analisis Faktor – Faktor yang Mempengaruhi Kualitas Pengerjaan Shuttle Protector
Get PDFThis research designed necessary orthogonal array and than determine factors that influence the quality of shuttle protector production process at Mitra Utama. The research was done for horizontal injection molding machine and only considered machine and material factors. Using Taguchi technique, L934 orthogonal array was chose as the experiment design and time as the measured response. By performing One-sample Kolmogorov-Smirnov test, Bertlett test, analysis of variance and pooling up analysis, it was found that the operating cylinder pressure and screw conveyor speed significantly influence the quality of shuttle protector protector production process at Mitra Utama. The best levels are 80 bars for the operating cylinder pressure and 110 rpm for the screw conveyor speed
Analisis Setting Parameter Mesin Thermoforming
Get PDFPermasalahan yang sering muncul pada saat mengoperasikan mesin Thermoforming pada industri kecil coklat praline
adalah menentukan kondisi operasional setting parameter yang terbaik sehingga akan diperoleh kualitas kualitas hasil
cetakan plastik yang baik, tanpa cacat, dan umur pakai cetakan lama.
Metode Taguchi dipergunakan dalam penelitian ini untuk mernperoleh kondisi operasional mesin Thermoforming
yang optimal sehingga akan diperoleh cetakan plastik yang sempurna dan dapat mengurangi jumlah cacat yang terjadi.
Array Orthogonal yang digunakan dalam penelitian ini adalah (L

Hasil penelitian menunjukkan hanya satu factor yang paling berpengaruh untuk menghasilkan cetakan plastik yang optimal.
Level terbaik menurut analisis pooling up mean, yaitu ketebalan plastik di-set pada level 3 dengan ketebalan plastik
1,0 mm. Level terbaik menurut hasil analisis pooling up SN Ratio, yaitu ketebalan plastik di-set pada level 1 dengan
ketebalan plastik 0,3 mm dan suhu pemanasan di-set pada level 2 dengan suhu 125°C. Hasil Responce Surface Method
menunjukkan setting parameter yang optimal adalah nilai eksperimen yang mendekati nilai Y

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
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
