ABSTRACT
Vindyo Lufftaratama, NIT: 51145231N, 2019, “Optimization Of Navigation Equipment Radar When Passing ALKI On Motor Tanker Galunggung” Nautical Department, Diploma IV Program, Merchant Marine Polytechinc Of Semarang,1st Supervisor: Captain Hadi Supriyono M.M., M.Mar, 2nd Supervisor: Purwantono, S.Psi, MPd
Radar will be very useful when bad weather, foggy conditions and sailing at night especially if shipping instructions such as flares, buoys, hills or buildings are visually unobservable. So prospective ship officers must understand and understand to use radar navigation equipment, because in the lines of ALKI or shipping it is prone to collision and runaway hazards. Then the ship's officers must be observant when passing through the shipping lanes when using the radar on board. A method must be applied in accordance with existing procedures. This can be done well if the ship officer as the implementing operator has the knowledge to operate the radar properly. The purpose of this study was to determine the role of radar navigation devices when passing through ALKI, to find out what obstacles occurred on the radar when passing ALKI, and to find out the operation of the radar when in a narrow cruise line when passing ALKI. In writing this essay, the author describes the radar optimization method as a basis for solving existing problems. The method used in this study is descriptive (if viewed in terms of the level of presentation) and also qualitative (if viewed from the method of data processing), then analyzed by the SHEL method to determine the problem of each factor and USG data analysis techniques (Urgency, Seriusness, Growth ) to determine the problem that is the top priority. In this case the data collection technique is in the form of an approach to objects through observation, direct interviews with respondents and using documents and data related to radar optimization.From the results of the research conducted, problems were found in radar optimization. Procedure for operating the radar is less than optimal due to incomplete manual book intuction, lack of maintenance of radar navigation equipment, the influence of the surrounding environment can result in a decrease in radar performance, lack of crew knowledge of radar navigation equipment. The suggestion of the author is that Officer III as an officer responsible for navigation equipment must understand how to operate the radar properly and correctly when passing ALKI (Indonesian Archipelago Sea Groove)
Penggunaan Alat Navigasi Radar Saat Melewati Alki Di Kapal MT. Galunggung

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
