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
Kendali Tegangan Output Buck Converter Menggunakan Arduino Berbasis Simulink Matlab
No full textThe rapid development of technology to date has made many electrical and electronic equipment that require a direct current (dc) voltage source whose output voltage can be adjusted to the needs of the user. There are several direct voltage levels that are commonly used by electrical and electronic equipment. To get a direct voltage that can be used for various equipment, a direct voltage source that can be varied according to need is required. One way to convert a dc voltage source to a lower dc voltage source is by using a buck converter circuit. This study proposes a buck type direct current converter is porposed to use the Arduino uno as a PWM signal generator circuit to control to control the 24 volt input voltage. The converter output voltage regulation is implemented through a potentiometer and Arduino programming using the simulink Matlab. In this research, a buck converter is tested with output voltage feedback so that the output voltage remains stable. The result of the test that have been carried out show that the buck converter designed in this study has worked well in accordance with objectives. This can be seen from the buck converter output voltage that is in accordance with the reference voltage using a potentiometer that is included in the simulink Matlab program
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
SAMPAH PLASTIK DALAM FENOMENA LINGKUNGAN
Get PDFABSTRAK
Sekarang ini kehidupan manusia tidak bisa lepas dari penggunaan plastik. Plastik terdiri dari bahan anorganik buatan yang sangat sulit diuraikan secara alami, Oleh karena itu, penggunaannya dapat dikatakan merugikan bagi lingkungan apabila digunakan berlebihan contohnya ketika sampah plastik mencemari sungai, pantai, hutan dan lain sebagainya. Selain itu sampah plastik mempunyai keragaman dari segi bentuk dan sifat seperti transparan, kering atau basah. Berdasarkan hal itu pencipta tertarik mengangkat sampah plastik ke dalam karya seni lukis dengan tema”Sampah Plastik Dalam Fenomena Lingkungan” yang berarti, penggambaran terhadap bahan buangan sintetis beserta hubungannya dengan daerah sekitar baik realitas dan dampak negatif yang melingkupinya, untuk selanjutnya bagaimana pencipta mengekpresikan objek sampah plastik, mengolah teknik, menyusun elemen seni rupa dan bisa menangkap pesan serta kaitannya dengan fenomena lingkungan sekitar, sehingga mampu memberikan manfaat bagi pencipta, masyarakat dan lembaga.
Dalam mewujudkan ide serta tema-tema pada karya seni lukis, melalui proses penjajagan, percobaan, persiapan, pembentukan dan penyelesaian akhir. Dalam penciptaan karya seni lukis, mengorganisir elemen-elemen serta unsur-unsur seni rupa yang dipadukan dengan teknik sesuai kemampuan yang ditekuni selama proses belajar, dengan penerapan warna untuk mencapai karakter serta suasana pada karya yang diwujudkan secara realistik. Kesan yang dicapai adalah ringan, padat, natural, karakteristik dan kesan meruang serta memperlihatkan detail objek pada masing-masing karya. Diterapkan dengan teknik plakat, blok dan kering dengan menggunakan cat minyak dengan memakai kuas, dilakukan tahap demi tahap secara menyeluruh, agar dapat tercipta karakteristik objek sampah plastik serta objek pendukung lainnya. Dalam perwujudan objek, diungkapkan melalui gagasan serta imajinasi, sehingga dapat merepresentasikan sampah plastik serta situasinya ke dalam karya seni lukis.
Dengan demikian melalui 10 karya yang digarap, dapat merepresentasikan sampah plastik serta situasi lingkungan, yang diungkap secara naturalis, realistik, dan metaforik, melalui hal tersebut dapat tercipta makna yang komunikatif dan mampu menggetarkan jiwa pencipta dengan harapan penikmat merasakan hal yang sama.

ABSTRACT
PLASTIC WASTE IN THE PHENOMENON OF ENVIRONMENT
Now this man's life can not be separated from the use of plastic. Plastics consists of artificial inorganic materials are very difficult to be described in a natural. Therefore, its use can be said to be harmful to the environment when used as an example of excessive plastic waste polluting the rivers, beaches, forests, and so forth. In addition, plastic waste has diversity in terms of shape and properties such as transparency, dry and wet. Based on that the creators are interested in lifting the plastic waste into works of art with the theme "Waste Plastics in Environmental Phenomena" which means, the depiction of the synthetic waste material and its relationship with the area around both the reality and impact surrounding negatife, to further express how the creator object trash plastics, process engineering, composing elements of art and can capture the message and its relation to the phenomenon of the surrounding environment, so as to provide benefits to the creators, society and institutions.
In realizing the ideas and themes of the paintings, through the assessment process, trial, preparation, formation and final settlement. In the creation of works of art, organizing elements and elements of art are combined with appropriate technical capabilities occupied during the learning process, with the application of color to achieve the character and atmosphere of the work embodied in realistic. The impression that is achieved is a light, solid, natural, characteristics and spatial impression and show object details on each paper. Applied to the plaque technique, block and dry using oil paint with a brush, do a thorough step by step, in order to create an object characteristic of plastic waste and other supporting objects. In the embodiment of the object, expressed through ideas and imagination, so as to represent the plastic trash and circumstances into paintings.
Thus through ten works under cultivation, can represent plastic waste and environmental situation, which is revealed in a naturalistic, realistic, and metaphorically, through it can be created meaning communicative and able soulful creator in hopes audience felt the same way.

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
