No full textAbstrak Peranan sistem pengendali di era industri modern sangat penting, khususnya pengendali motor induksi 3 fasa. Kondisi ini menuntut lulusan Sekolah Menengah Kejuruan (SMK) Kompetensi Keahlian (Komli) Teknik Instalasi Tenaga Listrik (TITL) memiliki kompetensi sesuai tuntutan industri, salah satunya kompetensi merencana dan merangkai rangkaian pengendali. Implikasinya, SMK harus mampu melakukan inovasi dan mengembangkan media pembelajaran trainer sistem kendali dalam mendukung pencapaian kompetensi tersebut. Metode penelitian mengadaptasi dari Research and Development (R & D) yang disesuaikan tujuan penelitian. Penelitian ini bertujuan menghasilkan media pembelajaran trainer pengendali motor induksi 3 fasa multifungsi layak digunakan, ditinjau dari hasil validasi trainer oleh ahli media pembelajaran dan sistem kendali; hasil ujicoba trainer pada pembelajaran untuk mengetahui hasil belajar siswa ranah kognitif dan psikomotor serta respon siswa. Media pembelajaran trainer multifungsi pengendali motor 3 fasa sistem Direct On Line, Forward-Reverse dan Star-Delta yang dihasilkan layak digunakan. Bentuk kemasan kotak hitam jinjing kerangka akrelik dengan dimensi 60cm x 40cm x 25cm. Rating hasil validasi trainer 92,13 % (sangat baik); rata-rata hasil belajar siswa ranah kognitif 87,08 dan psikomotor 90,75 (rata-rata 88,92) melampaui kriteria ketuntasan minimal (KKM) sebesar (≥75); dan rata-rata respon siswa 95,14% (sangat baik). Dapat disimpulkan trainer multifungsi pengendali motor 3 fasa sistem Direct On Line, Forward-Reverse dan Star-Delta yang dihasilkan layak dan dapat digunakan sebagai media pembelajaran mata pelajaran kendali elektromekanik di SMK ditinjau dari hasil validasi ahli, hasil belajar siswa ranah kognitif dan psikomotor serta repon siswa. Kata kunci : kelayakan, trainer multifungsi, hasil belajar dan respon siswa Abstrack The role of the control system in the modern industrial era was very important, particularly control of the induction motor 3 phase. This condition requires graduates of vocational high schools (SMK) Competency expertise installation of electrical power Engineering has competence according to the demands of the industry, one of whom planned competence and stringing a series of controllers. By implication, the vocational high schools must be able to innovate and develop the learning media trainer system full in support of the achievement of the competencies Research methods adapted from Research and Development (R & D) tailored research purposes. This research aims to produce learning media trainer induction motor 3 phase controller multifunction feasibility, reviewed the results of the validation by an expert media trainer learning and control systems; the results of tests the trainer on the learning to know the results of student learning cognitive and psychomotor domains as well as the response of the students. Learning medium trainer 3 phase motor controller multifunction system for Direct On Line, Forward-Reverse and Star-Delta produced viable use. Form black box akrelik frame with carry case dimensions of 60 cm x 40 cm x 25 cm. results validation Rating trainer 92,13% (very good); the average student learning results of cognitive domain 87,08 and psychomotor domains 90,75 (average 88,92) exceeded the minimum completeness criteria (KKM) registration (≥75); and the average student response 95,14% (very good). Multifunctional trainer can be inferred the governing motor 3 phase Direct On Line system, Forward-Reverse and Star-Delta produced viable and can be used as a medium of learning subjects in electromechanical control vocational high schools (SMK) reviewed the results of a validation expert, student learning outcomes cognitive and psychomotor domains as well as repon students.

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
