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
PENGGUNAAN MODEL EPIDEMI SIR (SUSCEPTIBLES-INFECTED-REMOVED) PADA PENYEBARAN PENYAKIT HIV/AIDS DI MAKASSAR
Get PDFPenelitian ini menggunakan data jumlah penduduk Kota Makassar dan jumlah individu yang terinfeksi penyakit HIV/AIDS mulai tahun 2014 s.d 2016 diperoleh model penyebaran penyakit HIV/AIDS dengan penggunaan model epidemi SIR dengan titik ekuilibrium (S,I)=(15625,14276795). Kemudian berdasarkan nilai eigen matriks Jacobi diperoleh titik (S,I) tersebut bersifat stabil asimtotik dengan nilai – nilai eigen -0,01 dan -91,4. Selanjutnya, diperoleh bilangan reproduksi dasar, yakni 91,471 yang menunjukkan bahwa satu individu yang terinfeksi, rata-rata dapat menularkan kepada 91 hingga 92 jiwa individu rentan terhadap penyakit HIV/AIDS. Dalam hal ini, penyakit tersebut di Kota Makassar akan bersifat endemik dalam kurun waktu 100 tahun ke depan. Hal ini dibuktikan dengan simulasi numerik menggunakan software Maple dan Matlab dengan melihat perilaku solusi penyelesaian S(t) dan I(t) untuk kurun waktu yang relatif lama
Application of Cluster Analysis Using Agglomerative Method
Get PDFImproving the quality of human resources is the main supporting factor in increasing national productivity in various fields and development sectors. The government's productive investment activities that spur the nation's competitiveness in the global era prioritize Indonesia's education development. This study aims to cluster provinces in Indonesia based on educational indicators using the Agglomerative method consisting of the Average Linkage and Ward methods. Data collection is based on documentation techniques obtained from Statistics Indonesia in 2018. Data analysis used hierarchical cluster analysis consisting of data standardization, determining the size of the similarity or dissimilarity between data, the clustering process with a distance matrix, and seeing the characteristics of the cluster results formed. The second clustering method is by doing the initial grouping and determining the excellent cluster based on the average standard deviation ratio to the standard deviation between groups. Clustering results show the Ward method with the number of collections as many as 4 clusters and produces a ratio with a value of 0.01 smaller than the Average Linkage method. It shows that the cluster analysis method using the Ward method has better group accuracy quality than the Average Linkage method
Penggunaan dan Pengembangan Model Epidemi Sir pada Penyebaran Penyakit Tuberkulosis di Sulawesi Selatan
Get PDFPenelitian ini menggunakan analisis data deskriptif sebagai tahap awal yang berdasarkan data jumlah penduduk Sulawesi Selatan dan jumlah individu yang terinfeksi penyakit Tuberkulosis tahun 2016 dan 2017. Tahap kedua, menentukan asumsi-asumsi sehingga dibentuk model penyebaran penyakit Tuberkulosis, yakni model epidemi SIR dengan titik ekuilibrium Tahap ketiga, menentukan nilai eigen matriks Jacobi diperoleh di titik (S,I)=(1563,172072437) dengan sifat kestabilan, stabil asimtotik dengan nilai – nilai eigen -0.05 dan -5506,27 Selanjutnya, diperoleh bilangan reproduksi dasar, yakni R0= 275,404 yang menunjukkan bahwa satu individu yang terinfeksi, rata-rata dapat menularkan kepada 275 hingga 276 jiwa individu rentan terhadap penyakit Tuberkulosis. Tahap terakhir, berdasarkan data hasil penularan tersebut menunjukkan bahwa penyakit Tuberkulosis di Sulawesi Selatan akan bersifat endemik dalam kurun waktu 100 tahun akan datang. Interpretasi berdasarkan simulasi numerik menggunakan software Maple dan Matlab juga menunjukkan bersifat endemik dengan melihat perilaku solusi penyelesaian dan untuk kurun waktu yang relatif lama
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
