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
Model Simulasi Karakteristik Gelombang Perairan sebagai Studi Perencanaan Dalam Rekiamasi Pantai.
Full text linkStruktur gelombang dalam gelombang dialam adalah fenomena yang sangat rumit diamati dan ini banyak tergantung pada kondisi fisis yang mengatur gerak dan struktur gelombang tersebut. Terdapat beberapa perilaku fisis yang mempengaruhi struktur gelombang, yaitu sifat dispersi, disipasi, ketaklinieran, difraksi, refraksi, shoaling serta kondisi topografi dasar perairan pantai.
Model numerik gelombang laut di perairan pantai denganmenggunakan persamaan pengatur kombinasi refraksi-difraksi pada slope landai, dibangun dengan menggunakan metoda beda hingga. Persamaan gelombang kombinasi refraksi-difraksi pada topografi pantai slope landai, dibangun dari persamaan gerak arah x dan y serta persamaan kontinuitas. Persamaan ini dibangun oleh Berkhoff (1972), dan kemudian dikembangkan oleh Watanabe dan Maruyama (1986).
Model gelombang kombinasi diatas dijabarkan terhadap komponen¬komponen kecepatan arah x dan y dan penurunannya berdasarkan pada variabel-variabel: kecepatan fase, elevasi permukaan air, faktor disipasi karena gelombang pecah di surf zone yang dinyatakan dalam faktor disipasi energi.
Solusi dan perhitungan analitik persamaan gelombang pada daerah slope landai yang bergantung waktu tidak representatif untuk medan gelombang disekitar struktur perairan pantai. Untuk ini kajian secara numerik perlu dilakukan untuk menyelesaikan dan menganalisis persamaan ini dengan metode beda hingga. Di sini, diskritisasi persamaan dibangun berdasarkan sel-sel (grids), diperoleh dengan membagi daerah studi menjadi sel-sel ruang yang sisi-sisinya masing-masing dalam arah sumbu x dan y, dimana sumbu x arahnya dari laut dalam menuju garis pantai dan sumbu y sejajar dengan garis pantai. Proses iterasi ditentukan dalam parameter waktu (At), dengan memberikan syarat batas dan awal. Hasil yang diperoleh tinggi gelombang akibat pendangkalan, refraksi dan gelombang pecah, serta simulasi gelombang disekitar break water (pemecah gelombang) Validasi model dilakukan dengan membandingkan hasil pengukuran fisik laboratorium oleh Kim et al. 1999.
The wave structure in the physical phenomenon is complicated to be investigated. The structure depends on the physical conditions. There are some physical behavior, which determine this structure, i.e. dispersive, dissipative, nonlinearity, diffraction, refraction, shoaling and the bottom topography on shore. In this research we study two main projects concerning to the water surface waves.
The model of numeric ocean wave in coastal water is to build equation of regulator of combination of refraction-diffraction at sloping slope, woke up by using finite different method. The surface wave equation model of the refraction-diffraction combination on the mild sloping bottom on shore, is governed of the moving equation in x and y directions, and the continuity equation. This equation is derived by Berkhoff (1972) and then developed by Watanabe and Maruyama (1986).
This combination wave model is described respect to the velocity component in x and y directions, and this derivation based on the variables; the phase velocity, the water surface elevation and dissipation factor because of the point break wave in surf zone which is represented in the energy dissipation factor. The solution and analytical computation of the time dependent wave equation on the mild sloping bottom is not representative for wave field near the coastal structure. So we use the numerical approach to handle this analysis by using the finite difference methods. By the finite difference methods, we discrete the wave equation based on grids, which is done by dividing the study zone in to the space grids on x and y directions, where x axis direction tend to on shore and y axis direction tend to the line on shore. The iteration process is determined by the time parameter (At). The Result of which is obtained high wave effect of shoaling, refraction and break wave, and also simulation wave around break water. The validity of this model is demonstrated by comparing the result of measurement of physical laboratory by Kim et al. 1999
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
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
