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
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

Proses bongkar muat menjadi salah satu hal yang wajar atau dapat dikatakan
pasti kita temui dalam dunia pelayaran, dimana adanya kegiatan pengangkutan dan
penurunan muatan baik ditempat asal maupun tujuan. Kebanyakan dari kapal curah
menggunakan alat crane sebagai alat bantu untuk proses bongkar muat. MV. LGH
PROSPER merupakan kapal bulk carrier yang menggunakan crane pada saat
kegiatan bongkar muat. Pada saat pelaksanaan bongkar muat terjadi permasalahan
patahnya boom crane No. 2 yang dialami MV. LGH PROSPER pada saat proses
bongkar di Morosi, Sulawesi Tenggara. Tujuan dari penelitian ini adalah untuk
mengetahui faktor, dampak, dan upaya yang harus dilakukan pada saat terjadinya
patah boom crane No. 2 di MV. LGH PROSPER.
Metode yang digunakan peneliti dalam penelitian ini adalah metode deskriptif
kualitatif. Metode diagram fishbone digunakan untuk menganalisis faktor yang
menyebabkan masalah pada rumusan masalah pertama. Metode pengumpulan data
yang digunakan peneliti dalam penelitian ini adalah observasi, wawancara, dan
dokumentasi. Dalam melaksanakan penelitian, informan yang dilibatkan peneliti
adalah Chief Officer, Second Officer, dan A/B kapal MV. LGH PROSPER.
Hasil penelitian ini menunjukan bahwa faktor yang menyebabkan patahnya
boom crane di MV. LGH PROSPER diantaranya adalah faktor internal yang terdiri
dari luffing sheave, kurangnya perawatan wire luffing, dan operrator crane.
Sedangkan faktor eksternal yaitu usia wire yang terlalu tua, angin, panas, dan uap
dari air laut. Dampak dari patahnya boom crane terhadap kegiatan bongkar muat
yaitu kegiatan bongkar terhambat, kegiatan bongkar muat tidak efisien, dan
kerugian biaya bagi perusahaan. Upaya untuk menghindari patah boom crane agar
kegiatan bongkar muat berjalan lancar adalah melakukan penurunan boom crane
yang patah, melanjutkan kegiatan bongkar muat dengan mengoptimalkan 3 crane,
melakukan perbaikan boom crane yang patah, serta mengoptimalkan perawatan dan
pengecekan pada crane
ANALISIS KEBOCORAN PADA CYLINDER HYDRAULIC CRANE DI MV.GULF MAS

Avip Prasetyo, 2021, NIT: 531611206077 T, “Analisis Kebocoran Pada Cylinder Hydraulic Crane Di MV.Gluf Mas” Skripsi Program Studi Teknika, Program Diploma IV, Politeknik Ilmu Pelayaran Semarang, Pembimbing I: F.Pambudi Widiatmaka,S.T.,M.T. Pembimbing II: Vega Fonsula Andromeda,S.ST,S.Pd,M.Hum.
Crane adalah suatu alat permesinan bantu yang berkerja berdasarkan hukum pascal dimana crane dapat mengangkat dan menurunkan beban yang berat dengan menggunakan penggerak actuator dengan media minyak hidrolik bertekanan tinggi. Salah satu bagian terpenting pada crane adalah seal hydraulic yang berfungsi sebagai perapat untuk menjaga minyak tidak keluar, yang tentunya tidak boleh timbul kebocoran pada bagian tersebut karena akan menggangu pengoperasian dari crane itu sendiri.
Pentingnya crane di atas kapal maka diperlukan metode yang tepat untuk memecahkan masalah kerusakan yang terjadi pada crane hydraulic dengan metode Fault Tree Analysis dan Urgenct, Seriousness, Growth, dan juga menggunakan metode deskriptif kualitatif untuk mengetahui foktor penyebab, dampak yang terjadi, dan upaya yang dilakukan.
Mengingat pentingnya crane hydraulic yang dapat memindahkan kontainer yang harus mendapatkan perhatian dan perawatan seara intensif dan continue, agar crane tersebut dapat beroperasi dengan lancar dan tahan dalam jangka waktu yang lama. Jika crane hydraulic mengalami permasalahan maka akan mengakibatkan keterlambatan jadwal bongkar muat barang, hal ini sangat merugikan sekali pada perusahaan pelayaran pada umumnya. Adapun faktor yang menyebabkan kebocoran pada crane hydraulic diantaranya adalah Plain maintenance system yang tidak sesuai, minyak hidrolik yang tercampur air, dan seal hydraulic yang rusak
