LAJU PERUBAHAN MUKA AIR LAUT DI WILAYAH PERAIRAN PANTAI BENGKULU DENGAN MENGGUNAKAN SATELIT ALTIMETRY
Full text linkAbstrak: Pada akhir-akhir ini di sepanjang pantai barat Provinsi Bengkulu mengalami abrasi pantai dengan kecepatan sampai 2,5 m/thn. Masalah ini dapat menimbulkan kerugian ekonomi, menggangu sumber daya di wilayah pesisir (seperti agribisis, rekreasi, pariwisata) dan merusak sistem transportasi serta kawasan pemukiman terutama para nelayan. Penelitian tentang tingkat kerusakan pantai abibat abrasi telah dilakukan, akan tetapi apa yang menjadi penyebab abrasi pantai belum diketahui secara jelas, apakah disebabkan oleh perubahan iklim (naiknya permukaan laut) atau disebabkan oleh faktor tektonik (perubahan relief permukaan tanah). Oleh karena itu penelitian ini bertujuan untuk mengidentifikasi penyebab abrasi pantai di Bengkulu secara komprehensif. Penelitian ini dimulai dengan mengamati perubahan muka air laut dengan satelit Altimetry. Periode data yang diolah pada saat ini baru sampai 7 tahun yakni dari tahun 2004 sampai tahun 2011. Hasil pengolahan data menunjukkan bahwa perubahan muka air laut secara tahunan. Disamping itu dengan menggunakan pemodelan sederhana kita dapat mengamati bahwa: perubahan muka air laut pada selang waktu ini terlihat bahwa untuk daerah perairan Muko-Moko memiliki laju yang lebih besar dibandingkan dengan daerah perairan Bengkulu. Akan tetapi laju ini masih hamper sama dengan laju perubahan muka air laut secara global. Untuk mendapatkan pola perubahan muka air laut yang akurat, masih dibutuhkan penambahan periode data yang akan diolah. Disamping itu diperlukan model yang lebih akurat sehingga model yang dibuat dapat menjelaskan data perubahan muka air laut di wilayah perairan Bengkulu.

PELATIHAN KOMPUTER DAN MICROSOFT OFFICE BAGI PERANGKAT DESA UNTUK OPTIMALKAN PELAYANAN MASYARAKAT
Full text linkTingkat keterampilan perangkat desa Desa Barumanis Kecamatan Bermani Ulu Kabupaten Rejang Lebong dalam mengoperasikan komputer menjadi persoalan pokok dan serius dalam memberikan pelayanan kepada masyarakat. Persoalan tersebut terselesaikan melalui pelatihan komputer khususnya microsoft office bagi perangkat desa. Pelaksanaan program ini dilakukan melalui pendekatan partisipatif yang menerapkan metode pendidikan, pelatihan dan praktik. Peserta diberikan evaluasi pra dan pasca pelatihan untuk mengevaluasi kemampuan peserta sebelum dan setelah pelatihan. Hasil menunjukkan bahwa peserta sudah terbiasa dan lancar mengetik dokumen menggunakan teknik sepuluh jari. Peserta mampu menyelesaikan semua tugas dan ujian akhir pelatihan dengan sangat baik. Tidak ada peserta yang mendapati nilai ujian praktik di bawah 60. Peserta yang mendapat nilai 60 < x < 70 sebanyak 20% (6 orang) 70 < x < 85 sebanyak 50% (15 orang), dan nilai x > 85 sebanyak 30% (9 orang). Kemampuan peserta meningkat signifikan, sehingga diharapkan mampu memberikan pelayanan yang optimal dan prima di era digital
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
