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

PROFIL BERPIKIR KREATIF SISWA DALAM MEMECAHKAN MASALAH TIPE INVESTIGASI MATEMATIK DITINJAU DARI PERBEDAAN GENDER
No full textArtikel ini bertujuan untuk mendeskripsikan profil berpikir kreatif siswa dalam memecahkan masalah tipe investigasi matematik ditinjau dari perbedaan gender. Dalam pemecahan masalah tipe investigasi matematik memungkinkan siswa untuk melakukan percobaan yang berbeda-beda cara untuk mendapatkan solusi atas masalah yang diajukan. Oleh karena itu, unsur-unsur berpikir kreatif seperti fleksibilitas dan kebaruan mempunyai peluang yang besar untuk muncul, tentunya juga disertai unsur kefasihan dan keterincian yang mendukung investigasi matematik yang baik. Ujicoba telah dilakukan, subyek ujicoba adalah empat orang siswa sekolah dasar kelas V, dua orang laki-laki dan dua orang perempuan. Ujicoba menggunakan dua masalah investigasi matematika. Hasil ujicoba menunjukkan bahwa siswa laki-laki dalam berpikirnya lebih terbuka, sehingga dengan ketelitiannya siswa laki-laki mampu berpikir matematis yang abstrak untuk mumunculkan kebaruan dan kefleksibilitasannya dengan menemukan pola-pola jawaban yang berbeda dan memperumumkan hasil yang ditemukannya. Sedangkan subyek perempuan dalam berpikirnya masih pada percobaan-percobaan kongkrit, dan kesulitan untuk melakukan pengamatan abstrak terhadap bilangan-bilangan yang abstrak sehingga pola-pola umumnya tidak ditemukan. Namun subyek perempuan lebih fasih dalam mengungkapkan jawaban tertulisnya.

Creating Joyful Atmosphere In Mathematics Learning For Elementary School Students By Implementing Kopermatik Aids
No full textThe goal of the present study is to create joyful atmosphere in mathematics learning by implementing Kopermatik (the Box Games Realistic Mathematics), a set of mathematical teaching aids that are equipped with realistic mathematics worksheets and they are designed in the form of the game. Kopermatik development is an attempt to enrich the variety of aids and math games, for which its implementation in schools is to create a joyful atmosphere. The population of this research is students of SDN 44 Ampenan the academic year 2009/2010 (high grade classes) and 2010/2011 (low grade classes). The classroom setting uses cooperative model, four students in one group, who learn while playing Kopermatik aids and fill in worksheets that contain developing concepts and realistic problems. Based on a questionnaire filled out by teachers who are involved in the study, all teachers feel good, easy and helpful to learn to use Kopermatik aids. Students have good attitude and appreciation by learning using Kopermatik, where 97.1% students enjoy learning with Kopermatik, 93.1% enjoy learning in groups, and 81.2% of students feel confident to be in front of the class. The effectiveness of learning with Kopermatik is high, i.e the understanding of the concept of learning outcomes achieved a score of 82.5, while the ability to solve realistic problems reaches a score of 76.4. These results indicate that the implementation of Kopermatik for all grades of students in SDN 44 Ampenan can make students more active, creative and joyful in mathematics learning.

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
