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
Simulasi Sebaran Temperatur Pelat Logam Tipis Besi dan Kuningan Berbasis Matlab
Full text linkSimulating the temperature distribution of iron and brass metal thin plates based on matlab has been performed. This simulation aimed to study iron plate and brass plate conductors of the temperature distributionbased on conduction mechanism on cartesian coordinate system. The initial temperature in all parts of the thin plate is room temperature, except at left side and right side of the plate is 100 oC. Through numerical calculation of heat conduction equation by Finite Difference Method, we got that the temperature at center thin plate for 10 second is 63,26oC and 62,08 oC for brass thin plate and iron thin plate, respectively
Kajian Kemampuan Berpikir Kritis Pada Konsep Fisika Dari Sudut Pandang Filsafat
Full text linkThe ability to think critically is one of the important skills that everyone must have, including when studying physics. Physics is the science that studies the universe and all the phenomena that occur in it. To understand physics concepts, critical thinking skills are needed to analyze and evaluate the information obtained. This research aims to examine critical thinking skills on physics concepts from a philosophical perspective. This study was carried out using the literature study method. This research has the implication that critical thinking skills need to be trained and developed from an early age, especially in studying physics. Critical thinking skills training can be done through various activities, such as discussions, presentations and problem solving
Simulasi sederhana pada hukum pendinginan Newton
Full text linkA simple simulations on Newton’s cooling law has been performed. This simulations aims to study correlation of the newton cooling constant at temperatures to cooling times. This reseach is displayed in GUI Matlab (Guide Using Interface). The input required is initial temperature, ambient temperature, cooling constant, and cooling time. Through numerical calculation of the Newton’s cooling equation with Eulerian Method, we got that the time to reach the ambient temperature of each cooling constant is 59 seconds, 31 seconds, and 20 seconds respectively
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
Pengembangan Model Miniatur Kereta Magnetic Levitation Sebagai Media Pembelajaran Fisika Pada Materi Gaya Magnetik
No full textThe purpose of this research is to produce a development product in the form of a Magnetic Levitation Train miniature model that can be used by teachers and students in the physics learning process on magnetic force material in class XII. This study uses research and development methods. The research was conducted through several stages, namely the first stage reviewing curriculum standard notes. The second stage is the design of the tool, making a miniature model of the Magnetic Levitation Train and the use of a miniature model of the Magnetic Levitation Train in the learning process. The third stage is the implementation stage, the miniature model of the Magnetic Levitation Train was tested on high school student of class XII to measure students against the miniature model of the Magnetic Levitation Train as a tool to help students understand the concept of magnetic force. The instrument uses a Likert Scale. With three stages, the researcher succeeded in making a miniature model of the Magnetic Levitation Train that was worthy of being one of the learning media on magnetic force material by obtaining information that the validation results by experts, material personnel and students obtained a very good level of measurement which was in the interpretation range of scores 80-100% so it is necessary to develop a miniature model of the Magnetic Levitation Train to be even better in further research
