Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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

Efektivitas Pemberian Beta Carotene Terhadap Hippocampus Tikus Wistar Betina (rattus Norvegicus) Menopause Untuk Mencegah Neurofibrillary Tangles (nfts)
Get PDFLatar Belakang: Alzheimers Disease (AD) adalah gangguan neurodegeneratif
kronis umum pada orang tua berusia 65 tahun dan sering terjadi pada wanita
menopause. AD ditandai dengan penurunan fungsi kognitif akibat hiperfosforilasi
protein tau yang membentuk Neurofibrillary Tangles (NFTs). #914-carotene dikenal
sebagai antioksidan kuat yang mampu melindungi sel otak dari kerusakan
oksidatif dan mencegah pembentukan NFTs. Namun, penelitian yang melaporkan
efek pemberian #946-carotene pada tikus model menopause untuk mencegah NFTs masih terbatas.Tujuan: Penelitian ini bertujuan untuk membuktikan pemberian #946-carotene
memiliki efek positif terhadap hippocampus tikus wistar betina (Rattus
Norvegicus) menopause untuk mencegah Neurofibrillary Tangles (NFTs).
Metode: Penelitian eksperimental ini menggunakan metode Randomized
Controlled Trial (RCT) dengan desain Post Test Only Control Group Design
menggunakan 21 ekor tikus wistar betina yang dibagi menjadi 3 kelompok, yaitu
kontrol normal (kelompok I), ovariectomy (kelompok II), dan ovariectomy dengan
#946-carotene dosis 3 mg/kgBB/hari selama 21 hari (kelompok III). Sampel otak
tikus diambil dan dihitung jumlah NFTs di area CA1, CA3, dan DG hippocampus.
Data dianalisis dengan uji One Way ANOVA dan uji LSD.
Hasil Penelitian: Hasil penelitian menunjukkan bahwa didapatkan perbedaan
signifikan (p0,05) dalam jumlah NFTs di area CA1, CA3, dan DG hippocampus
antara kelompok I dengan II, kelompok II dengan III, dan tidak ada perbedaan
signifikan antara kelompok I dengan III.
Kesimpulan: Kesimpulan penelitian ini adalah pemberian #946-carotene dengan
dosis 3 mg/kgBB/hari selama 21 hari terbukti memiliki efek positif untuk
mencegah NFTs pada hippocampus tikus yang diinduksi model menopause
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
