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
METODE DISCRETE WAVELET TRANSFORM DAN ALGORITMA K-NEAREST NEIGHBORS UNTUK DETEKSI JANTUNG ARITMIA
Get PDFAritmia merupakan suatu gejala dari kelainan detak jatung atau irama jantung. Saat ini aritmia merupakan kelainan jantung yang cukup serius karena bila tidak ditangani dengan serius dapat berujung pada kematian. Kelainan jantung tersebut dapat didiagnosis melalui prosedur elektrokardiogram (EKG). Elektrokadiogram ini merupakan salah satu metoda diagnosa yang paling sering digunakan untuk mengetahui kondisi kesehatan jantung pada pasien. Berbagai macam sistem kesehatan yang mengadaptasi perekam EKG semakin banyak, contohnya pada pengklasifikasian kelainan jantung ini (aritmia).
Pada tugas akhir ini, akan digunakan metode Discrete Wavelet Transform (DWT) dan algoritma K-Nearest Neighbors (KNN). Sinyal EKG ini diektraksi ciri dengan metode DWT yang hasil keluaranya merupakan ciri, jenis wavelet antaralain Daubechies, Symlets, Coiflets, dan Bior. Sedangkan KNN digunakan untuk mengklasifikasi ciri sinyal dari sinyal EKG. Parameter jarak antara lain Euclidean, Cosine, Cityblock, Minkowski, dan Chebyshev.
Hasil dari tugas akhir ini adalah sebuah sistem yang mampu untuk dapat mendeteksi, dan mengklasifikasi dengan hasil akurasi dari beberapa skenario pengujian. Skenario pengujian I memiliki hasil akurasi terbaik sebesar 99,71% dan waktu komputasi selama 8,52 detik yang didapat dengan menggunakan parameter jenis wavelet bior4.4, level dekomposisi 2 dengan koefisien detail dengan nilai K=1 dan parameter jarak Euclidean. Skenario pengujian ke II dan III, pengujian ini merupakan pengujian kombinasi kombinasi dari parameter statistik, kombinasi yang memiliki nilai tertinggi yaitu 6 kombinasi yaitu mean, standar deviasi, variance, skewness, kurtosis, entropy yaitu 99.71% dengan waktu komputasi 8,52 detik. Skenario pengujian IV, pengujian ini merupakan pengujian untuk setiap nilai K yaitu 1, 3, 5, 7, dan 9. Nilai K terbaik adalah 1 dengan nilai akurasi 99,71 dan waktu komputasi 8,52 detik. Skenario pengujian ke V, pengujian ini merupakan pengujian untuk setiap parameter jarak yaitu Euclidean, cosine, cityblock, chebychev dan minkowski. Parameter jarak terbaik adalah Euclidean dengan nilai akurasi 99,71% dan waktu komputasi 8,52 detik.

?Penerapan UCP Atas Ketidaksesuaian Dokumen Pada Transaksi Letter of Credit Dalam Putusan Mahkamah Agung Nomor : 141 PK/PID.SUS/2009?
No full textHasil penelitian menunjukkan bahwa perlindungan hukum terhadap bank
pembayar secara normatif telah diatur dalam Uniform Customs and Practice for
Documentary Credit(UCP-DC-600), yang pada intinya menyebutkan bahwa bank
dapat mentolerir terhadap adanya penyimpangan, atau ketidaksesuaian terhadadap
dokumen L/C dengan pembatasan bahwa penyimpangan tersebut bersifat non
substansial. Hal ini dikuatkan dengan dasar hukum berupa yurisprudensi atau
putusan hakim terdahulu terhadap kasus yang sama hal ini yang disebut dengan
doktrin Kesesuaian Mutlak. Sedangkan perlindungan hukum terhadap bank
pembayar secara empiris yaitu bahwa bank pembayar dapat diberi kesempatan untuk
memperbaiki kesalahan-kesalahan kecil dalam dokumen-dokumen L/C tersebut agar
bank pembayar dapat memperoleh reimbursment, atau pembayaran kembali dari
bank penerbit (issuing bank)dan transaksi eksporimpor dapat terus berjalan,
sepanjang proses perbaikan tersebut tidak memerlukan waktu lama dan tidak sampai
melampaui jangka waktu yang telah ditentukan dalam perjanjian L/C tersebut. Dan
juga yang terpenting dalam draft perjanjian Letter of Credit yang dibuat dicantumkan
klausul tambahan mengenai pilihan hukum yang akan dipakai oleh para pihak
apabila dikemudian hari terjadi sengketa yang melibatkan pengadilan
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
