Pengembangan Modul Praktikum Berbantuan PhET Simulation Berbasis Inkuiri Terbimbing Pada Materi Momentum, Impuls dan Tumbukan Kelas X SMA
Full text linkPhysics is a subject that has many concepts that must be adapted to the curriculum. Therefore, in the implementation of learning practicum activities are needed as a support so that students can understand a concepts that is difficult to understand. In addition, based on the Circular Letter of the Ministry of Education and Culture Number 4 of 2020, shifting face-to-face learning to the online system. So that the practicum can be carried out virtually using PhET (Physics Education Technology). In conducting virtual practicum, a media that can support learning is needed in the form of a practicum module. And also in learning activities, the material presented by educators is not necessarily all students are able to accept and understand. Thus, the learning model that can be applied is guided inquiry-based learning. This learning media was created whit the aim of facilitating and assisting student in understanding the material presented by educators. This research is a Research & Development (R & D) research with a 4D research model. This learning media is validated and assessed by experts in their fields as well as educational practitioners. The physics practicum module assisted by PhET Simulation based on guided inquiry on momentum, impulse and sollision materials for class X high school obtained an average value od each validation, namely the material expert validation test 87,50% with a very feasible category, the media expert validation test 86,67% with very feasible category, linguistics expert validation test 79,55% with very feasible category, and 94,69% education practitioner test with very feasible category. These result indicate that the physics practicum module assisted by PhET Simulation based on guided inquiry on momentum, impulse and collision material for class X high school that was developed is very feasible to be tested on students
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
MOBERAK (Motor Bebas Bahan Bakar Ramah Lingkungan)
Full text linkThe vehicle is an important requirement for daily activities. The increasing number of vehicles in Indonesia from year to year correlates with the worsening air quality, especially in big cities like Jakarta. Data also shows that 70% of air pollution in Jakarta comes from motorized vehicles that use fossil fuels. One source of energy that can be an alternative solution is electric-powered vehicles because they have advantages, which are not producing pollution. Electric vehicles generally use lithium batteries as a source of electric power. Lithium batteries that have been used up are generally just thrown away without going through the processing so that they will contaminate water and soil. Therefore, we want to make vehicles that are not dependent on fossil fuels, produce no pollution, and can do auto charging electric so they don't rely on PLN electricity. This vehicle can charge independently because it has an electromagnetic coil on the rear wheel that will produce GGL induction from the wheel rotation when the bike is moving. We call this vehicle MOBERAK (Environmentally Friendly Fuel-Free Motorbike)

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
