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
LAPORAN INDIVIDU PRAKTIK PENGALAMAN LAPANGAN (PPL) SMA NEGERI 7 YOGYAKARTA JALAN M.T. HARYONO 47, YOGYAKARTA
Full text linkUniversitas Negeri Yogyakarta (UNY) sebagai salah satu lembaga yang menghasilkan tenaga kependidikan telah berusaha meningkatkan kualitas pendidikan agar mampu menghasilkan lulusan yang lebih baik dan lebih profesional. Salah satu model yang dipilih adalah pelaksanaan PPL (Praktik Pengalaman Lapangan) secara terpadu. PPL merupakan pembentukan dan peningkatan kemampuan profesional. Maksud diadakannya program PPL adalah pemberdayaan pendidikan di sekolah dan pelatihan profesionalisme para mahasiswa PPL itu sendiri.
Praktik Pengalaman Lapangan (PPL) merupakan mata kuliah wajib yang harus ditempuh oleh setiap mahasiswa kependidikan di Universitas Negeri Yogyakarta. Dalam hal ini, penyusun melaksanakan Praktik Pengalaman Lapangan (PPL) di SMA Negeri 7 Yogyakarta yang terletak di wilayah kota Yogyakarta. Praktik pengalaman lapangan ini bertujuan mendapatkan pengalaman tentang proses pembelajaran dan kegiatan persekolahan lainnya yang digunakan sebagai bekal untuk menjadi calon tenaga pendidik. Praktikan diharapkan mampu untuk memiliki nilai, sikap, pengetahuan, dan keterampilan yang dibutuhkan sebagai seorang pendidik. Pelaksanaan kegiatan PPL dimulai dari observasi hingga pelaksanaan PPL yang terbagi menjadi beberapa tahap yaitu persiapan mengajar, pelaksanaan mengajar, dan evaluasi hasil mengajar. Dari hasil observasi dilaksanakan pada tanggal 4 Maret 2014 diketahui beberapa permasalahan di sekolah maupun potensi yang sebenarnya dapat dikembangkan di sekolah tetapi belum diberdayakan. Adapun Kegiatan PPL yang dilakukan meliputi tahap persiapan, praktek mengajar, dan analisis hasil. Praktik mengajar dilaksanakan mulai tanggal 23 Juli 2014 sampai 17 September 2014. Pada tahap pelaksanaan, mahasiswa diberi kesempatan mengajar sebanyak 18 kali. Kegiatan mengajar dilaksanakan setelah konsultasi Rencana Pelaksanaan Pembelajaran kepada guru pembimbing terlebih dahulu. Pelaksanaan PPL dilaksanakan di kelas XI IPS 1 dan XI IPS 2.
Hasil dari pelaksanaan PPL selama kurang lebih dua bulan di SMA Negeri 7 Yogyakarta ini dapat dipetik hasilnya oleh mahasiswa berupa penerapan ilmu pengetahuan dan praktik keguruan dalam di bidang Pendidikan Sosiologi yang diperoleh di bangku perkuliahan. Meskipun demikian, tetap masih ada hambatan dalam pelaksanaan PPL. Penyusun menghimbau supaya hubungan kerja sama antara pihak sekolah dan UPPL-UNY tetap terjaga dengan baik
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
