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
Rehabilitation application program for obesity adolescent using structural equation modelling
Get PDFObesity is one of the most important public health problems of the late twentieth century. Report by World Health Organization (2015) found the national prevalence of obesity in Indonesia was increased from 12.2% in 2007 to 16.8% in 2015 and reached 11.9% for the aged 6 to 12 years old. This research is conducted to identify the factors influencing obesity and their impact on obese adolescent. There are five influencing factors; nutrition, genetic, physical activity, socioeconomic, health awareness. This research was conducted in Padang, West Sumatera, Indonesia including 386 students in the age of 11-15 years old. Results of Partial Least Square Structural Equation Modelling analysis shows that there are 16 indicators from 47 indicators that provide a significant impact on each factor they represent. The significant indicators include; snack consumption, nap schedules, and pocket money. In addition to that, analysis results on factors that affect obesity in adolescents show that the nutrition factor has the most influence on obesity adolescent with T = 5.911 followed by genetic = 4.321, physical activity = 3.174, and socioeconomic = 2.283. Meanwhile health awareness factor does not significantly affect on obesity in adolescents. However, the role of health awareness can be seen based on the correlation test results whereby all factors such as nutrition have the largest correlation with health awareness factors. The results of these statistical analysis will be used as a reference for the content on rehabilitation application program for obesity in adolescents. The validity and usability test for the developed application program shows most of users were satisfied with the program. However, there were several users that found difficulty in using english based application. The result of this research can be a reference for the authority and nutritionist in making guidelines or treatment in order to prevent the increase of obesity among adult and adolescents
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
Grafik Kendali Multivariat Cumulative Sum Based On Projection Pursuit (Ppcusum) Pada Data Multivariat Normal
No full textDalam proses produksi akan selalu terdapat produk yang berada di bawah standar dari perusahaan atau mengalami cacat secara kualitas. Salah satu metode yang dapat digunakan untuk melakukan pengendalian kualitas produk adalah dengan menggunakan Statistical Process Control (SPC) dengan alat yang biasa digunakan adalah grafik kendali (Control Chart). Penelitian ini menggunakan empat karakteritik kualitas dari semen OPC yang terdiri dari free lime, ??3, ???, mesh untuk menentukan apakah semen yang diproduksi berada dalam standar atau cacat secara kualitas. Untuk karakteristik kualitas lebih dari satu alat yang digunakan adalah grafik kendali multivariat. Penelitian ini menggunakan grafik kendali multivariat Cumulative Sum Based on Projection Pursuit yang merupakan pengembangan dari grafik kendali MC1 dan optimal CUSUM dengan kemampuan mendeteksi pergeseran proses ketika arah pergeseran yang tidak terbatas. Hasil yang didapatkan adalah ketika batas kendali (h) = 12,3294 titik pertama yang berada di luar batas kendali adalah sampel ke 10 sedangkan untuk h = 13,7009 dan 18,0027 sampel pertama yang berada di luar batas kendali adalah sampel ke 16. Ketika terdeteksi sampel yang berada di luar batas kendali maka dilakukan pendeteksian waktu dari pergeseran proses. Dengan menggunakan batas kendali (h) sebesar 18,0027 pergeseran proses sudah terlihat pada sampel ke 8 dengan arah pergeseran yang paling optimal pada ? 0?= (0,962416 0,235219 0,125824 0,05094)
