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
Political Advertising: Strategi Partai Politik dalam Pemilu: Strategi Partai Politik dalam Pemilu
No full textPerkembangan periklanan politik, terutama di negara demokrasi, mengalami kemajuan yang sangat pesat sejak kemunculannya pada awal tahun 1950 di AS. Efektivitasnya membuat kandidat dan partai politik yang bertarung tidak ragu mengeluarkan zaya jutaan dolar untuk mengungguli lawan politiknya. Berbeda dengan periklanan kontroversial, Periklanan Politik sering menyampaikan pesan-pesan politik yang bersifat negatif, mendeskreditkan lawan politik, sebagai cara mudah merebut suara pemrih
Teknik-Teknik Penelitian Kuantitatif dalam Ilmu Sosial
Full text linkDalam ilmu-ilmu sosial, pun ilmu komunikasi, dikenal dua pendekatan yang penting untuk memahami dan menjelaskan gejala-gejala sosial, yakni pendekatan kuantitatif dan pendekatan kualitatif. Pendekatan kuantitatif biasanya dikaitkan dengan paradigma positivisme sedangkan pendekatan kualitatif dikaitkan dengan paradigma pos-positivisme. Akhir-akhir ini kritik memang sering ditujukan pada paradigma positivisme ini karena ia dinilai mereduksi manusia menjadi sekadar angka-angka dan data-data kuantitatif. Namun, ternyata pendekatan ini pun tetap bermanfaat, bertolak dari cara manusia menghasilkan pengetahuan yang biasanya menggabungkan abstraksi dan observasi empiris Di sin, fokus pembahasan, di antaranya, pada pengkonstruksian skala-skala pengukuran dan cara membuat beberapa jenis skala yang cukup akrab dalam pendekatan kuantitatif
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
Teori Media-Marxist: Sebuah Pengantar
Full text linkTeori Media-Marxist mengasumsikan media sebagai arena pertarungan ideologi berbagai kelas. Dalam perspektifnya, para profesional media menikmati ilusi otonomi dan tersosialisasikan dalam kerangka norma budaya dominan. Media dianggap memiliki kerangka interpretasi yang sesuai dengan budaya dominan. Sementara, khalayak media sendiri lebih sering menegaskan dan mengontekskan kerangka tersebut karena ketidaksiapan menghadapi sistem makna alternatif yang memungkinkan mereka menolak definisi yang ditawarkan media secara konsisten. Bertitik tolak dari asumsi ini, maka teori Media-Marxist menawarkan cara pandang baru untuk menganalisis media dengan sejumlah konsep kunci: media sebagai cara produksi, media sebagai amplifier, hegemoni ala Gramsci, sampai pada text-reading ala Stuart Hall. Kendati demikian, sejumlah hal harus dicermati dalam penerapan teori Media-Marxist pada riset-riset media. Lyle mendefinisikan sembilan kelemahan teori Media-Marxist—beberapa di antaranya bersumber dari keyakinan bahwa dinamika masyarakat digerakkan sepenuhnya oleh perjuangan kelas, dan bahwa konflik senantiasa harus diselesaikan melalui cara-cara revolusioner
