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
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
Development of Mathematics Learning Media Based on Discovery Learning Integrated with Inderapura Culture to Improve Mathematical Problem Solving Ability for Junior High School Student of Grade VIII
No full textBased on the preliminary analysis conducted at SMP Negeri 2 Pancung , the students' mathematical problem solving ability was still low. The low ability of students to solve mathematical problems caused by (1) teachers do not use worksheet in the learning process, (2) The learning process that has not facilitated students to construct their own knowledge. Based on this problem, researchers developed mathematical learning media based on discovery learning integrated with Inderapura culture to improve students' mathematical problem solving abilities.This research was a development research conducted with the Plomp development model. This model was carried out in 3 stages. In the first stage was the preliminary research phase and it was needs analysis, curriculum analysis, student analysis and concept analysis. In the second stage was the development or prototype phase which was designed in accordance with the integrated learning discovery model of Inderapura culture. In the third stage was the assessment phase which aimed to see the effectiveness of learning media by conducting large group field tests. The subjects of this study were the eighth grade students of SMPN 2 Pancung Soal. Data collected by documentation, observation, interviews, questionnaires, and tests. Data from observations, questionnaires and tests were analyzed quantitatively and strengthened by the results of the documentation analyzed descriptive qualitative.The results showed that mathematics learning media in the form of lesson plan andworksheet based on discovery learning integrated with Inderapura culture for grade VIII in the second semester of Junior High School were produced by fulfilling valid, practical and effective categories. Validity was tested in terms of content, usage, language and graphics. Applicable in terms of application, time, ease of use and effective in terms of potential impacts on students' mathematical problem solving abilities. The conclusion was mathematics learning mediawas feasible to be used as reference material in mathematics learning, especially materials for constructing flat side spaces in gradeVIII of SMP N 2 Pancung
Effectiveness of the use of activity, classroom discussion, and exercise (ACE) Teaching cycle in elementary linear algebra course at Padang State University
Full text linkThe major objective of this study was to develop, implement, and evaluate the use of the Activity, Classroom discussion, and Exercise (ACE) teaching cycle approach in an Elementary Linear Algebra course. The main focus of the study was to identify the effects of the ACE teaching cycle approach on students’ engagement and learning. The Elementary Linear Algebra course was delivered at the Mathematics Education Study Program of Padang State University, Indonesia.An action research methodology was adopted for the study and the constructivist theory was used as a theoretical framework. This study used mixed methods to collect, describe, and interpret the data. The data were collected through focus group discussion, classroom observations, questionnaire, concept maps, students’ reflective journals, and the lecturer’s research journal. The participants in this study consisted of 37 students enrolled in the Elementary Linear Algebra course during the January-June 2011 semester. The ACE teaching cycle approach that was implemented in this study consisted of three steps. The first step in this cycle was the concept maps activity. This activity encouraged students to prepare for the topics that would be discussed in the class. The next step was classroom discussion which provided a social context in which the students could work together to solve mathematics problems. Finally, exercises were assigned as homework. In this part, students practised solving mathematics problems and wrote reflective journal.Students’ involvement in the ACE teaching cycle approach in the Elementary Linear Algebra course improved their engagement in mathematics learning in the three domains of cognitive engagement, affective engagement and behavioural engagement. The approach has given students the opportunity to develop their understanding on concepts and procedures, problem solving ability, and communication ability
