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
PERBEDAAN HASIL BELAJAR MATEMATIKA SISWA SMP YANG BERKEPRIBADIAN EXTROVERT DAN INTROVERT PADA POKOK BAHASAN SISTEM PERSAMAAN LINIER
Full text linkThe purpose of this research is to know the difference between students’ mathematic learning outcomes in junior high scholl between extrovert and introvert personality in mathematic linear equation material. The type of the research is experimental research with quantitative approach. The subject of this research is the eight grade students in junior high school who have extrovert and introvert personality. The data collecting methods are documentation and questionnaire. The results of the research are the value of t test = 5.082 and t table = 2.045 it’s mean that t tes > t table so Ha is accepted and Ho is rejected. Based on the data findings, it can be concluded that there is different of students’ mathematic learning outcomes in junior hight school between extrovert and introvert personality in the materials of mathematic linear equation system. The suggestion is that the teacher must be a motivator for students, and always care about the different personality of his/her students in order to find the best method or learning model that is comfortable to assist themto get good mathematic learning outcomes.Key Words: mathematic learning outcomes, extrovert and introvert personalit
Analisis Beberapa Peubah dan Objek Merk Pembalut Wanita dengan Menggunakan Metode Biplot
Full text linkTujuan penelitian ini untuk mengetahui informasi-informasi tentang Kedekatan antar objek , besar kecilnya keragaman peubah, Hubungan antar peubah dan Nilai peubah pada suatu objek menggunakan Metode Biplot pada data primer dari survey Produk Pembalut Wanita sebagai Bagian Perencanaan Strategi Pemasaran. disimpulkan bahwa kedekatan antar objek dapat dilihat dari plot yang berdekatan dan berdasarkan gambar biplot, atribut yang memiliki hbungan yang cukup dekat antara lain adalah feminim dan mudah didapat dan kedua atribut ini dimiliki oleh merk pembalut wanita Softex, Protex, Softness, dan Honeysoft. Untuk mengetahui besar kecilnya keragaman peubah (merk pembalut wanita) yaitu digambarkan dengan panjang pendeknya vector. Semakin panjang suatu vector maka semakin besar variansnya. Dan dari data di atas peubah yang memiliki varians terbesar adalah Softex sedangkan peubah yang memiliki varians terkecil adalah Kotex. Hubungan antar peubah yang dilihat dari posisi plot pada bidang cartesius. Bila berada pada kuadarn yang sama dan posisinya berdekatan, maka peubah-peubah tersebut salin bersaing. Contohnya adalah persaingan Kotex dan laurier, persaingan Charm dan Whisper berada di kuadran yang sama. Contoh lainnya adalah persaingan antara Softex, Softness, Protex dan Honeysoft walaupun keempat merk pembalut ini terletak di kuadran yang berbeda namun posisi masing-masing plotnya berdekatan. Nilai peubah pada suatu objek, halini memperlihatkan atribut yang dimiliki oleh masing-masing peubah. Yaitu Softex, Softness, Protex dan Honeysoft yang memiliki kesamaan atribut mudah diperoleh dan feminim. Laurier dan Kotex juga memiliki atribut yang sama yaitu harganya yang terjangkau dan sesuai untuk remaja. Sedangkan Whisper dan Charm sesuai untuk wanita-wanita yang aktif dan percaya diri
Model Intervensi untuk Mengetahu Dampak Krisis Moneter dan Kenaikan Harga BBM Terhadap Data IHK
Full text linkSalah satu indikator untuk melihat besarnya dampak suatu peristiwa atau kebijakan di Indonesia adalah Indeks Harga Konsumen (IHK). Krisis moneter pada pertengahan tahun 1997 mengakibatkan lonjakan harga-harga komoditas yang dibutuhkan masyarakat Lonjakan harga-harga komoditas merupakan salah satu penyebab utama naiknya IHK. Selain krisis moneter, kenaikan harga BBM diduga juga berpengaruh terhadap IHK. Penelitian ini fokus pada analisis dampak krisis moneter dan kenaikan BBM terhadap data IHK nasional. Metode statistik yang digunakan adalah analisis deret waktu dengan model intervensi. Hasil analisis intervensi menunjukkan bahwa dampak terbesar dan masih berlangsung hingga hari ini adalah dampak dari krisis moneter dan disusul dampak kenaikan harga BBM yang terasa hingga sebulan setelah kenaikan
Kata Kunci: model intervensi, pulse function, step function, IHK
