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

No full textProfil Status Identitas Remaja: Analisis Kluster Berdasarkan Tiga Dimensi Identitas
Full text linkKonsep pembentukan identitas telah berkembang pesat dan dapat dijelaskan dengan berbagai cara, seperti model tiga dimensi identitas yang lebih menekankan pada dinamika proses pembentukan identitas. Selain itu, model tiga dimensi identitas juga dapat digunakan untuk mengklasifikasikan lima status identitas yang meliputi achievement, early closure, moratorium, searching moratorium, dan diffusion. Penelitian ini bertujuan untuk mendeskripsikan profil status identitas remaja di Surabaya. Penelitian ini akan memaparkan profil lima status identitas berdasarkan tinggi dan rendahnya komitmen, eksplorasi mendalam, dan peninjauan kembali komitmen. Penelitian ini melibatkan 1468 remaja di Surabaya yang berusia 12-21 tahun (M =16.802, SD = 2.484). Pengambilan data dilakukan dengan metode convenience sampling dan menggunakan Utrecht-Management of Identity Commitments Scale versi Indonesia. Analisis data dilakukan dengan menggunakan K-Means Cluster untuk mengklasifikasikan lima status identitas berdasarkan skor komitmen, eksplorasi mendalam, dan peninjauan kembali komitmen. Hasil penelitian menunjukkan bahwa sebagian besar remaja berada pada status moratorium. Remaja dengan status moratorium cenderung untuk mengubah komitmen yang telah dimiliki sebelumnya dan kurang mencari berbagai informasi mengenai identitasnya. Oleh karena itu, temuan ini mengindikasikan bahwa sebagian besar remaja di Surabaya masih belum mencapai status identitas yang optimal. Selain itu, penelitian ini juga menemukan perbedaan status identitas berdasarkan jenis kelamin dan kelompok usia remaja. Secara umum, temuan penelitian ini perlu menjadi perhatian untuk orang lain yang signifikan bagi remaja seperti orang tua dan teman dalam menyediakan dukungan yang diperlukan remaja selama proses pembentukan identitas
Validitas Struktur Internal Self-Determination Scale versi Indonesia: Pengujian Struktur Faktor, Reliabilitas, dan Invariansi Pengukuran
Full text linkSelf-Determination Scale (SDS) telah digunakan untuk mengukur determinasi diri, kesadaran terhadap diri sendiri, dan kesempatan untuk menentukan pilihan tetapi belum terdapat penelitian yang menguji properti psikometri dari SDS. Penelitian ini bertujuan untuk mengevaluasi validitas struktur internal dari SDS versi Indonesia. Penelitian ini melibatkan 703 remaja yang berusia 12-21 tahun yang sedang menempuh pendidikan di Kota Surabaya. Partisipan direkrut dengan teknik convenience sampling dengan cara menghubungi secara langsung dan melalui media sosial. Evaluasi validitas struktur internal dari SDS versi Indonesia meliputi struktur faktor, reliabilitas, dan invariansi pengukuran antar gender dan kelompok usia yang diuji dengan analisis konfirmatori faktor, reliabilitas komposit, dan analisis multi-kelompok. Hasil menunjukkan bahwa model bifaktor dari SDS versi Indonesia memiliki ketepatan model dan reliabilitas yang memuaskan. Namun, SDS versi Indonesia tidak memiliki invariansi pengukuran antar gender dan kelompok usia. Temuan ini mengindikasikan bahwa SDS versi Indonesia dapat digunakan untuk mengukur determinasi diri, kesadaran terhadap diri sendiri, dan kesempatan untuk menentukan pilihan tetapi tidak dapat digunakan untuk membandingkan skor antar gender dan kelompok usi
Psychometric Properties of Identity Style Inventory-5 Indonesian Version: Factor Structure, Reliability, and Criterion Validity
Full text linkThis research evaluated the psychometric properties of the Identity Style
Inventory-5 (ISI-5) Indonesian version using 763 adolescents aged 18-21 years. The
evaluation process was carried out by examining the factor structure, reliability, and
criterion validity using confirmatory factor analysis, composite reliability, and by
correlating with other measuring instruments. The analysis results indicated that the
ISI-5 version's factor structure with three factors of identity style and one identity
commitment is fit with the data and has good internal consistency. The correlation
between this version and other measuring instruments proves that it has fairly good
criterion validity. The results showed that the ISI-5 Indonesian version is a valid and
reliable instrument for measuring Indonesian adolescents' identity style and
commitment
