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
Rancang Bangun Mesin Pemipih Adonan Pizza Dengan Sistem Microcontroller
Full text linkPizza adalah hidangan gurih asal Italia sejenis adonan bundar dan pipih, yang dipanggang di oven dan biasanya dilumuri saus tomat serta keju dengan bahan makanan tambahan lainnya yang bisa dipilih sesuai selera. Keju yang dipakai biasanya mozzarella atau keju piza, bisa juga parmesan dan beberapa jenis keju lainnya. Seiring meningkatnya kebutuhan konsumen mengenai produk Pizza, maka diperlukan suatu mesin yang dapat mempercepat dan mempermudah produksi Pizza ini, yang mana sebelum dibuatnya mesin ini proses pemipihan adonan Pizza memerlukan waktu yang lama dan juga membutuhkan banyak tenaga, dengan mesin ini dapat mempermudah produksi dengan metode pemipihan yang sesuai dengan kebutuhan dari adonan Pizza tersebut. Rancang bangun Mesin Pemipih Adonan Pizza ini, menggunakan arduino nano sebagai controller untuk mengatur ketebalan pemipihan dan jeda waktu yang ditentukan. Menggunakan motor stepper sebagai penggerak dan sebagai pengatur motor menggunakan Driver A4988. Dalam proses pemipihan adonan menggunakan tuas press dengan diameter 200 m
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
Prototype Of Mask Recognition And Body Temperature In Real Time With Amg8833 Thermal Cam Sensor For Covid-19 Early Warning Based On Minicomputer
Full text linkOn April 19, 2020, the Republican Covid Task Force declared that the Covid-19 pandemic was a national disaster in Indonesia. At that time it was confirmed that there were 6575 cases and an increase of 5.23% compared to the previous day, then there were 5307 people in treatment which increased by 5.55% compared to the previous day, it was reported that 582 people died, which increased by 8.79 % compared to the previous day, and 686 recovered patients. WHO reports that the case fatality rate (CFR) or the death rate of Covid-19 cases in Indonesia reached 8.3%, which is twice the world's CFR. In this study, the main focus is to detect masks and body temperature used by visitors with various variations of masks on the market today, and next is to control the servo motor according to the detection conditions whether using a mask in real-time. Based on research on the system that has been tested, it shows that the components used to generate heat are very effectively used and can work as expected, and the MobilenetV2 method applied to the Raspberry Pi as the brain of the system can work as expected and has an accuracy rate of 99%. The AMG8833 sensor can read effectively at a maximum distance of 30 cm, the temperature reading deviation level is 0.1⁰C
Analisis Perancangan Casis Mobil Listrik dan Pembebanan Statik dengan Menggunakan SolidWorks
Full text linkPenelitian ini membahas analisis desain rangka kendaraan listrik serta evaluasi beban statis melalui SolidWorks, dengan penekanan pada peningkatan efektivitas kekuatan struktur dan distribusi beban pada rangka tipe ladder frame yang terbuat dari Aluminium 6061-T6. Metode kuantitatif yang berdasarkan pada Metode Elemen Hingga (FEM) diterapkan untuk menilai tegangan von Mises, deformasi, dan faktor keamanan dalam tiga skenario beban yang berbeda. Hasil simulasi menunjukkan bahwa pada beban 50 kg, tegangan maksimum yang terukur adalah 36,89 MPa, deformasi sebesar 1,48 mm, dan faktor keamanan 7,45. Pada beban 60 kg, tercatat tegangan 43,54 MPa, deformasi 1,71 mm, dan faktor keamanan 6,32. Sedangkan pada beban 70 kg, tegangan mencapai 50,20 MPa disertai deformasi 1,93 mm dan faktor keamanan 5,48. Semua nilai tegangan tersebut masih jauh di bawah batas luluh Aluminium 6061-T6 yang sebesar 275 MPa, sehingga membuat struktur dianggap aman dan stabil terhadap variasi beban. Dengan demikian, penggunaan SolidWorks terbukti efektif dalam menyediakan analisis rangka mobil listrik yang efisien, tepat, serta mendukung performa kendaraan listrik yang ringan dan hemat energi
