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
Klasifikasi Penyakit Daun pada Tebu dengan Pendekatan Algoritma K-Nearest Neighbors, Multilayer Perceptron dan Support Vector Machine
Get PDFSugarcane is a vital crop in Indonesia, serving as the primary raw material for sugar production. Unfortunately, leaf diseases in sugarcane often pose a serious threat, potentially causing significant economic losses. These diseases are typically characterized by leaf morphological changes, making early detection and accurate classification essential to prevent further spread. This study compares three algorithms for identifying sugarcane leaf diseases: K-Nearest Neighbors (KNN), Multilayer Perceptron (MLP), and Support Vector Machine (SVM). Each algorithm employs a different approach to recognize patterns and disease characteristics: SVM separates data by identifying the optimal hyperplane, KNN classifies based on the proximity of data to training data, while MLP, as an artificial neural network, can recognize more complex patterns. The deep learning model VGG16 was utilized for feature extraction from sugarcane leaf images to enhance classification accuracy. The dataset used comprises 8,200 images of sugarcane leaves, categorized into four classes: 2,050 images of Cercospora spot gray, 2,050 of common rust, 2,050 of northern blight, and 2,050 of healthy leaves. Each category was further divided into training and testing datasets in an 80:20 ratio, with 6,560 images for training and 1,640 images for testing. The results indicate that the MLP algorithm achieved the best performance, with accuracy, precision, and recall values of 97.4%. This establishes MLP as the most effective choice for classifying sugarcane leaf diseases
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
Pelatihan Troubleshooting Computer Pada Perangkat Kelurahan Dalam Peningkatan Pelayanan Prima Terhadap Masyarakat
Get PDFPerkembangan teknologi berdampak pada pembentukan kondisi untuk sistem yang baik. Perusahaan publik dan perusahaan swasta berlomba-lomba menciptakan lingkungan kerja dan persaingan memperebutkan SDM yang dapat menggunakan teknologi untuk meningkatkan produktivitas pekerjaan. Saat menggunakan teknologi, bisa dipastikan akan ada masalah saat digunakan Perangkat keras atau perangkat lunak. Kelurahan Karang Dalo memiliki 13 perangkat Kelurahan, diantara semua perangkat Kelurahan yang ada, hanya sedikit orang yang dapat mengoperasikan dan mengatasi troubleshooting komputer. Situasi ini secara tidak langsung dampaknya pada proses pelayanan tidak maksimal. Dengan adanya permasalahan tersebut hingga perlu diselenggarakan pelatihan Troubleshoothing computer baik perangkat keras ataupun perangkat lunak bagi pegawai Kelurahan untuk meningkatkan kemampuan pengoperasian komputer khususnya pada Kelurahan Karang Dalo Kecamatan Dempo Tengah Kota Pagar Alam
Implementasi Metode Random Sampling Pada Animasi Motion Grapich Herbisida Dan Fungisida
Get PDFPromosi sangat penting untuk mendukung kegiatan pemasaran. Saat mempromosikan sebuah produk masih menggunakan brosur, berbicara langsung dengan konsumen di lapangan sehingga memiliki banyak biaya, energi, kebutuhan waktu dan konsumen dan kurangnya ketertarikan koonsumen untuk membeli produk, oleh karena itu dengan pemanfaatan dari teknologi multimedia maka permasalahan tersebut diharapkan dapat diatasi. Pada penelitian ini menggunakan pengembangan model ADDIE, yang terdiri dari 5 langkah yaitu analisis, desain, pengembangan, implementasi dan evaluasi. Animasi ini dibuat oleh Adobe oleh Effect CS6 dan dirancang untuk mengukur level valid dalam animasi Alpha Tester ini untuk mengukur validitas animasi dengan ulasan ahli, yaitu yaitu ahli design, ahli media, ahli bahasa, ahli materi. Untuk mengukur pemahaman dan minat konsumen, penulis menggunakan teknik sampling dalam penelitian ini dan penggunaan formula pengambilan sampel lambat untuk menentukan jumlah responden dari populasi. Dari hasil tes oleh para ahli yang diperoleh dengan hasil validitas, menyatakan bahwa ekstensi animasi ini sangat valid dengan memberikan rata-rata 4.15 dari hasil nilai validitas, dan merupakan rata-rata 4.31 dari responden
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
