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
Analisis Stationkeeping Saat Proses Instalasi Mooring Line Pada FPSO 100.000 DWT Dengan Variasi Beban Lingkungan
No full textPenelitian tugas akhir ini menganalisis kemampuan stationkeeping FPSO 100.000 DWT selama proses instalasi mooring line di perairan Natuna dengan variasi konfigurasi tugboat. Metode time domain digunakan dengan software MOSES untuk memodelkan gerak FPSO, mooring system spread mooring, serta gaya tarik tugboat. Analisis dilakukan pada lima arah beban lingkungan (0°, 45°, 90°, 135°, dan 180°) dengan menggunakan data lingkungan pada 1 bulan. Evaluasi meliputi excursion FPSO (pada mode gerak surge, sway dan yaw), tegangan maksimum mooring line, serta kebutuhan bollard pull pada tiga konfigurasi tugboat yang berbeda. Hasil menunjukkan bahwa variasi konfigurasi tugboat berpengaruh signifikan terhadap excursion FPSO dan distribusi tegangan pada mooring line selama proses instalasi. Nilai excursion pada mode gerak surge terbesar terdapat pada konfigurasi pertama yaitu 4,940 m/m, mode gerak sway terbesar terdapat pada konfigurasi pertama dengan nilai 5,570 m/m, mode gerak yaw terbesar terdapat pada konfigurasi pertama dengan nilai 4,490 deg/m. Hasil analisis mooring line tension terbesar pada konfigurasi pertama senilai 134,230 ton dengan safety factor 4,782, tension terbesar pada konfigurasi kedua yaitu 122,09 ton dengan safety factor 5,258 dan tension terbesar pada konfigurasi ketiga yaitu 119,390 ton dengan safety factor 5,377. Dari ketiga konfigurasi, dapat disimpulkan tidak terdapat tension yang melebihi safety factor dari API RP-2SK yaitu ≥1,67. Dengan perhitungan tug efficiency dapat diketahui kebutuhan bollard pull pada gaya tarik pertama yaitu sebesar 84,910 ton, pada gaya tarik kedua sebesar 87,990 ton dan pada gaya tarik ketiga sebesar 90,430 ton.

This final project research analyzes the stationkeeping capability of a 100,000 DWT FPSO during the mooring line installation process in Natuna waters with variations in tugboat configurations. A time domain method was applied using MOSES software to model the FPSO motion, spread mooring system, and tugboat pulling forces. The analysis was carried out for five environmental load directions (0°, 45°, 90°, 135°, and 180°) using one-month environmental data. The evaluation covered FPSO excursions (in surge, sway, and yaw modes), maximum mooring line tensions, and required bollard pull for three different tugboat configurations. The results show that tugboat configuration variations significantly affect FPSO excursions and mooring line tension distribution during the installation process. The highest surge mode excursion was found in the first configuration at 4,940 m/m, the highest sway at 5,570 m/m also in the first configuration, and the largest yaw at 4,490 deg/m in the same configuration. The maximum mooring line tension occurred in the first configuration at 134,230 tons with a safety factor of 4,782, the second configuration at 122,09 tons with a safety factor of 5,258, and the third configuration at 119,390 tons with a safety factor of 5,377. From these results, it can be concluded that none of the tensions exceeded the safety factor required by API RP-2SK (≥1.67). Based on tug efficiency calculations, the required bollard pull was found to be 84,910 tons for the first configuration, 87,990 tons for the second, and 90,430 tons for the third configuration
Tinjauan Hukum Ekonomi Syariah terhadap jual beli daring
Get PDFPertumbuhan perdagangan secara digital semakin cepat dan akses internet semakin mudah, diprediksi pada tahun 2020 ini pengguna internet mencapai 64 persen penduduk Indonesia sebanyak 174 juta pengguna internet, sehingga membuat pelaku bisnis mengembangkan bisnis digital. Para pelaku bisnis membuka transaksi jual beli secara daring melalui berbagai media elektronik seperti media sosial, website, dan marketplace. Peluang dan kemudahaan bertransaksi secara online (daring) menjadi dasar lahirnya penjual baru yang mencapai 80 persen total pelaku bisnis jual beli daring. Sebagian besar yang dilakukan oleh penjual baru adalah akad jual beli tanpa kepemilikan barang. Seorang penjual melakukan akad jual beli barang milik penjual lain tanpa kepemilikan penuh. Cara ini dilakukan karena tidak memerlukan modal banyak dalam memulai usahanya. Namun dalam tinjauan Hukum Ekonomi Syariah tidak diperbolehkan bagi seorang penjual untuk menjual barang yang belum menjadi hak miliknya, seperti yang dilakukan oleh dropshipper dalam jual beli daring. Permasalahan jual beli daring secara dropship menjadi dasar untuk penelitian ini.
Tujuan penelitian adalah untuk menemukan akad yang dipakai dalam jual beli daring secara tanpa kepemilikan barang dan mengklasifikasikan jenis-jenis jual beli daring, sehingga bisa dikategorikan cara-cara yang sesuai dengan Hukum Ekonomi Syariah.
Metode yang digunakan dalam penelitian ini adalah kualitatif. Peneliti menggunakan metode kualitatif, dikarenakan jual beli daring bersifat dinamis dan berkembang cepat menuju inovasi-inovasi baru bidang teknologi jaringan internet. Transaksi jual beli daring yang semakin cepat perkembangannya membutuhkan analisis data yang kompleks, holistik dan penuh inovasi setiap waktu.
Hasil penelitian menunjukkan bahwa jual beli daring memiliki berbagai jenis sehingga hukum terhadap jual beli daring menunjukkan hal yang berbeda tergantung cara yang dilakukan dalam penjualan daring ini. Jual beli daring secara garis besar terbagi menjadi dua yaitu melalui cara reselling dan dropshipping, cara pertama yaitu reselling merupakan akad jual beli daring dengan kepemilikan penuh. Sedangkan dropshipping merupakan akad jual beli darin
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
