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
PENGARUH TEGANGAN PANEL SURYA TERHADAP NILAI TEGANGAN INDUKTOR SEBAGAI REKAYASA ENERGI ALTERNATIF
Get PDFElectromagnetic induction can be produced from the inductor winding. The number of turns affects the magnetic field produced, which is directly proportional to the input voltage applied to the coil. In this study, the output voltage of the solar cell as input to the primary coil of the inductor. Changes in the solar cell voltage affect the magnitude of the magnetic field so that it affects the amount of voltage flowing in the inductor. An inductor with a total of 600 turns is able to turn on the lights wirelessly compared to a coil with a small number of turns. By using a voltage from the solar cell of 13.22 V and the number of turns of 600 turns, it is able to turn on a lamp with a power of 5 Watt, 10 Watt, 15 Watt and 20 Watt with a power transfer distance of 5 cm.

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
PROTOTIPE PEMBANGKIT LISTRIK MEDAN MAGNET ELEKTRIS
Get PDFOne effort to overcome the electricity crisis is to reduce dependence on fossil energy, sources by utilizing alternative energy sources consisting of various energy that can be used from natural elements, magnetism is one alternative to natural element energy that can be utilized as a solution to reduce the impact of energy crisis, Electric magnetic field power plant is a method for generating electrical energy by providing rotation to the armature or cores that are in the area or path of the magnetic field so that the rotation of the core or armature can produce DC electrical energy according to the type of rotor and stator used, starting with a Dc 1 motor connected to a 12 Vdc battery which is connected in parallel with a Dc 2 motor using gear and bicycle chain then the positive and negative wires of the Dc 2 motor fill the current and super capasitor voltage (2.7 Vdc capacitor 10 Farad parallel 6 pieces) then strengthened by order The Dc amplifier then goes to the stabilizer circuit and charges the 12 Vdc battery so as to create a rotation on the Dc 2 motor shaft, to then be connected in parallel with a core shaft or a wounded armature surrounded by a magnet. So it produces a Dc voltage on the commutator core (positive and negative cables) 6-12 Vdc, depending on the amount of magnet provided around the core or armature and the rotational speed of the core, armature (the more magnets the magnetic field will get bigger and stronger so magnetic and electromagnetic flux can also be generated by a large nominal Dc voltage, while the higher the core or armature beam, the greater the voltage will be).
 
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
