Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Pengaruh Model Pembelajar Problem Solving Terhadap Hasil Belajar Mahasiswa PG-PAUD Universitas Nusantara PGRI Kediri pada Materi Peluang
No full textPenelitian ini bertujuan untuk mengetahui pengaruh penerapan model pembelajaran problem solving terhadap hasil belajar mahasiswa PG-PAUD Universitas Nusantara PGRI Kediri. Jenis penelitian yang digunakan adalah penelitian eksperimen semu (quasi eksperimen). Populasi dalam penelitian ini adalah semua mahasiswa PG-PAUD Universitas Nusantara PGRI Kediri yang sedang menempuh mata kuliah statistika inferensial tahun akademik 2016/2017 terbagi dalam 5 kelas. Pengambilan sampel dilakukan secara acak dan ditentukan 2 kelas sebagai sampel penelitian. Teknik pengumpulan data menggunakan teknik tes untuk mengukur hasil belajar khususnya pada materi peluang. Uji hipotesis yang digunakan adalah uji statistik parametrik Paired t-test. Hasil uji normalitas dan uji homogenitas menunjukkan bahwa data kedua sampel yang diambil berasal dari populasi yang berdistribusi normal dan mempunyai varians antar kelompok sama (homogen). Menurut hasil perhitungan diperoleh nilai t = 4,258 dengan nilai sig. = 0,0001. Perbedaan nilai mean antara kelompok eksperimen dan kelompok kontrol sebesar 9,07. Dengan demikian dapat disimpulkan bahwa penerapan model pembelajaran problem solving mempunyai pengaruh yang positif dan signifikan terhadap hasil belajar mahasiswa PG-PAUD Universitas Nusantara PGRI Kediri pada materi peluang. 
Analisis untuk Menemukan Informasi Kesalahan Konsep Siswa dalam Menyelesaikan Soal Berdasarkan Hasil Ujian Nasional (UN) Matematika SD Tahun 2012/2013 di Kota Kediri
No full textPenelitian ini bertujuan untuk menemukan informasi mengenai kesalahan konsep yang dilakukan siswa dalam menyelesaikan soal Ujian Nasional (UN) Matematika SD Tahun 2012/2013 di Kota Kediri. Informasi yang ditemukan meliputi: (1) atribut yang mendasari butir soal, (2) materi dalam soal yang menyebabkan siswa banyak melakukan kesalahan, (3) jenis kesalahan yang dilakukan siswa, (4) letak kesalahan konsep siswa yang dominan, dan (5) penyebab utama kesalahan konsep yang dilakukan siswa.
Jenis penelitian ini adalah penelitian deskriptif kuantitatif. Sumber data penelitian adalah lembar jawaban siswa dan lembar soal Ujian Nasional. Sampel penelitian berjumlah 41 sekolah dasar di Kota Kediri dengan jumlah siswa sebanyak 1.445 siswa. Pengumpulan data dilakukan dengan menggunakan metode dokumentasi. Instrumen penelitian divalidasi berdasarkan pertimbangan ahli (expert judgement). Data hasil penelitian yang berupa lembar soal dianalisis menggunakan analisis konten, sedangkan data yang berupa respon siswa dianalisis menggunakan CDM (Cognitive Diagnostic Models).
Hasil penelitian menunjukkan bahwa: (1) atribut yang mendasari butir soal UN Matematika SD ada 67 atribut, meliputi 4 atribut isi, 60 atribut proses, dan 3 atribut keterampilan; (2) materi yang menyebabkan siswa banyak melakukan kesalahan adalah materi geometri dan pengukuran; (3) jenis kesalahan tertinggi pada bilangan adalah kesalahan prosedur, jenis kesalahan tertinggi pada geometri dan pengukuran adalah kesalahan konsep, dan jenis kesalahan tertinggi pada pengolahan data adalah kesalahan penafsiran; (4) letak kesalahan konsep yang dominan pada bilangan adalah konsep dasar arithmetic dan konsep dasar bilangan, letak kesalahan konsep yang dominan pada geometri dan pengukuran adalah konsep dasar geometri dan pengukuran, letak kesalahan konsep yang dominan pada pengolahan data adalah konsep dasar statistika; dan (5) penyebab utama kesalahan konsep pada bilangan adalah tidak menerapkan operasi hitung dengan tepat, tidak memahami konsep bilangan berpangkat; penyebab utama kesalahan konsep pada geometri dan pengukuran adalah tidak menerapkan rumus, konsep, atau sifat-sifat bangun datar maupun bangun ruang dengan tepat; penyebab utama kesalahan konsep pada pengolahan data adalah tidak memahami konsep rata-rata, median dan modus dari data bentuk kumpulan maupun tabel
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
