PETA RESPON PERCEPATAN GETARAN TANAH SETIAP JENIS BATUAN GEOLOGI DI KOTA BENGKULU
No full textPerhitungan nilai percepatan getaran tanah maksimum di daerah Kota Bengkulu
dilakukan dengan menggunakan persamaan Kanai dengan meninjau nilai periode dominan
getaran tanah, jarak sumber gempa terhadap stasiun pengukuran dan magnitudo gempa
permukaan (Ms). Bengkulu merupakan daerah aktif gempa bumi yang secara geografis
terletak dekat dengan batas pertemuan lempeng antara lempeng Indo-Australia dengan
lempeng Eurasia. Penelitian ini dilakukan untuk mengetahui peta variasi nilai percepatan
getaran tanah maksimum setiap jenis batuan geologi di Kota Bengkulu. Batasan daerah
pengamatan terletak pada 30 44,32’LS- 30 54’LS dan 1020 14,59’ BT-1020 22,21’ BT. Data
yang digunakan dalam penelitian ini adalah data kegempaan Bengkulu selama 40 tahun
(1970-2010) dari BMKG Kepahiang dengan batasan sumber gempa bumi antara 20LS- 60
LS dan 1000BT– 1040BT dan data seismogram tiap jenis batuan yang direkam dengan
sensor DS-4A dan TDL-303 Digital Portable Seismograph serta perangkat lunak
DataPro.exe untuk menentukan frekuensi dominan getaran. Variasi percepatan getaran
tanah maksimum Kota Bengkulu berkisar 192,341-926,497 gal. Nilai percepatan getaran
tanah maksimum terbesar terjadi di sebelah barat Kecamatan Ratu Samban (Pantai
Panjang) dengan jenis batuan geologi Batu Gamping Terumbu dan nilai percepatan getaran
tanah maksimum terkecil terjadi di wilayah Kecamatan Muara Bangka Hulu dengan jenis
batuan geologi Endapan Rawa. Jenis geologi yang aman berdasarkan nilai PGA di Kota
Bengkulu adalah Endapan Rawa dan Andesit
KARAKTERISTIK ESTUARI SELAGAN JAYA KABUPATEN MUKOMUKO BENGKULU BERDASARKAN BILANGAN ESTUARI
No full textPenelitian tentang karakteristik dan tipe pasang surut telah dilakukan di Estuari
Selagan Jaya kabupaten Mukomuko Bengkulu. Penelitian ini bertujuan untuk mengetahui bagaimana karakteristik estuari berdasarkan bilangan estuari, besar elevasi air maksimum dan minimum serta karakteristik estuari berdasarkan data pasang surut.. Metode yang digunakan adalah pengamatan langsung data di lapangan dengan menggunakan alat rambu pasut, dan pengolahan data bilangan estuari menggunakan persamaan bilangan estuari sedangkan data pasang surut diolah dengan menggunakan metode Admiralty. Data yang diperoleh dari hasil penelitian adalah ketinggian elevasi muka air laut maksimum 1,50 m dan ketinggian muka air laut minimum adalah 0,10 m. Nilai bilangan estuari yang didapat dari hasil perhitungan besarnya 0,001 sehingga karakteristik estuari yang terjadi di estuari Selagan Jaya kabupaten Mukomuko Bengkulu adalah terstratifikasi dengan baik. Berdasarkan perhitungan dengan metode Admiralty didapat besar bilangan Formzal adalah 0,129 maka tipe pasang surut di estuari tersebut merupakan pasang harian ganda (semidiurnal) sehingga karakteristik berdasarkan data pasang surut adalah dalam satu hari terjadi dua kali pasang dan dua kali surut
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
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
