    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

Tujuan penelitian ini adalah untuk mengetahui dan mendapatkan kajian tentang pengaruh harga, kualitas produk, strategi pemasaran dan faktor spiritual quotient Terhadap Keputusan Pembelian Produk HNI di Business Centre HNI 2 Pangkalpinang. Penelitian ini merupakan penelitian deskriptif kuantitatif dengan jumlah sampel sebanyak 80 responden, sedangkan teknik pengambilan sampel menggunakan teknik purposive sampling. Pada penelitian ini variabel bebasnya terdiri dari harga, kualitas produk, strategi pemasaran dan faktor spiritual quotient, sedangkan variabel terikatnya adalah keputusan pembelian. Pengujian instrumen menggunakan uji validitas dan realibilitas. Sedangkan metode analisis data menggunakan analisis regresi linier berganda dengan uji t, uji F, dan koefisien determinasi. Hasil penelitian variabel independen X1 diperoleh thitung (4,431 ) > Ttabel ( 1,665 ), Variabel X2 thitung ( 5,485 ) > Ttabel ( 1,665 ), variabel X3 thitung ( 7,760 ) > Ttabel ( 1,665 ), dan variabel X4 thitung (5,417 ) > Ttabel (1,665 ). Maka variabel X1 berpengaruh secara parsial terhadap variabel Y, variabel X2 berpengaruh secara parsial terhadap variabel Y, variabel X3 berpengaruh secara parsial terhadap variabel Y, variabel X4 berpengaruh secara parsial terhadap variabel Y. Hasil uji F menunjukkan bahwa Fhitung ( 15,035) > Ftabel ( 2,49 ), sedangkan signifikansi adalah 0,000 < Alpha pada independen secara bersama-sama atau simultan mempengaruhi variabel dependen secara signifikan. Hasil analisis koefisien determinasi menunjukkan bahwa variabel independen mempengaruhi variabel dependen sebesar 79,4 %, dan sisanya 20,6 % dipengaruhi oleh variabel diluar penelitian
