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
IMPLEMENTASI METODA PARTICLE SWARM OPTIMIZATION PADAPEMBANGKIT PLTG PT. PUSRI
Get PDFOptimasi suatu pembangkit merupakan salah satu indicator keandalan sistem tenaga listrik, dalampengertian selalu diupayakan besar daya yang dibangkitkan harus sama dengan besar kebutuhan di sisi beban setiap saat. Pada unit pembangkit termal pertambahan beban akan mendorong pertambahan jumlah bahan bakar per satuan waktu, yang biasa disebut input output suatu pembangkit tenaga listrik. Analisa beban dan biaya bahan bakar suatu pembangkit tenaga listrik dikenal dengan istilah Economic Dispatch. Beberapa metoda konvensional yang sering digunakan dalam penyelesaian masalah ED adalah metoda Lagrange dan Dynamic Programming dan pada pendekatan heuristik adalah metoda Particle Swarm Optimization (PSO). Penghematan yang dapat diperoleh dengan menggunakan metoda Particle Swarm Optimization   (PSO)     pada pembebanan tenaga listrik sebesar 30,19 MW sampai dengan 34,08 MW adalah    Rp 3.423.370,73   sampai  dengan Rp 3.824.613,11 per-jam
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
Pengelolaan Berkelanjutan Sumberdaya Ikan Demersal Di Perairan Utara Kabupaten Lamongan Propinsi Jawa Timur
No full textSumberdaya ikan adalah sumberdaya yang
bisa diperbarui, namun sumberdaya ikan mempunyai batas-batas tertentu. Apabila
sumberdaya ikan dimanfaatkan tanpa batas atau tidak rasional serta melebihi
batas optimal/MSY ( maximum sustainable
yield ), maka dapat mengakibatkan kerusakan dan terancamnya kelestarian.
Oleh karena itu, untuk menciptakan pemanfaatan yang berkelanjutan, maka
diperlukan suatu pengelolaan terpadu untuk mengelola sumberdaya ikan. P erairan Utara Lamongan yang
berbatasan langsung dengan Laut Jawa berdampak pada keanekaragaman jenis ikan
yang tertangkap. Ikan yang tertangkap di perairan Utara Lamongan sangat
bervariasi mulai dari ikan-ikan pelagis besar, pelagis kecil, dan ikan demersal. Data statistik
perikanan PPN Brondong tahun
200 4 – 201 3 menyebutkan bahwa p ada kelompok
jenis ikan, pada periode sepuluh tahun terakhir ini (Tahun 2004-2013) volume
produksi ikan demersal mencapai rata-rata 82,58 % dari total volume produksi di
PPN Brondong yang terdiri dari hasil tangkapan alat tangkap dogol 80,79 % dan rawai 1,79 %. Tujuan dari penelitian adalah mengalisis
keberlanjutan status pemanfaatan ikan demersal unggulan berdasarkan pendekatan ekologi dengan metode produksi sur p lus , dinamika stok, pendekatan ekonomi dengan bioekonomi , dan pendekatan sosial dengan p enentuan alat tangkap yang sesuai
dio p erasikan di
Lamongan menggunakan metode AH P (Analytical
Hierarchy P rocess) untuk penyusunan strategi pengembangan perikanan demersal berkelanjutan. Metode yang digunakan dalam
penelitian ini ada 2, yaitu metode kuantitatif yang digunakan p ada saat
analisis p erikanan
berkelanjutan secara ekologi dan ekonomi ( p roduksi sur p lus dan bioekonomi) dan metode kualitatif yang
digunakan saat analisis alat tangka p yang sesuai dio p erasikan di p erairan utara Lamongan dengan metode AH P (Analytic
Hierarchy P rocess ) . Analisa data yang dilakukan terdiri dari analisis
penentuan jenis ikan unggulan dengan skoring ,
konversi alat tangkap dasar ,
analisis ekologi dengan model produksi surplus ( Schaefer,
Fox, dan Walter - Hilborn ) , analisis keseimbangan bioekonomi, dan analisis alat
tangka p yang sesuai
dio p erasikan di p erairan utara
Lamongan dengan metode AH P (Analytic

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
