Full text linkThe dynamics of coastal geomorphology depending on the rock making up the coastal and oceanographic processes that work. Coastal geomorphology dynamic process influenced by oceanographic processes and can result in the accretion process and coastal erosion. This study aims to determine the dynamics of the process of coastal geomorphology and oceanographic factors that influence the process. This study uses the case with the analysis of dynamics of geomorphological and oceanographic processes that influence in the region penlitian. The research data in the form of tides, currents and sediments in coastal areas. The results of the study be a type of tidal Daily Single with water level Z0 = 55.90; (MSL) 69.14 cm; (HHWL) = 135.48 cm; (LLWL) = 0.78 cm. Waves as high as 0.62 meters and wave period 4.1 seconds. The waves come from the Northeast will burst burst as high as 0.81 meters at a depth of 0.78 meters. Breaking waves at an angle of 19.22 degrees to the shoreline, will result in flow velocity along the coast is 0.98 m / sec.Coastal geomorphology consists of rugged coastal hills of volcanic material composed of tuffaceous sand and clastic limestone and non clastics limestone and limestones; type of geomorphologys was coastal flat composed of silty sand; coastal river estuary composed of silty sand; coastal erosion occurs berm erosion. Geomorphology dynamic process influenced by longshore currents that cause abrasion dominant in the study area.
Dinamika geomorfologi pesisir pantai tergantung pada batuan penyusun pesisir pantai dan proses oseanografi yang bekerja. Proses dinamika geomorfologi pesisir pantai di pengaruhi oleh proses oseanografi dan dapat berakibat terjadinya proses akresi dan erosi pesisir. Penelitian ini bertujuan mengetahui dinamika proses geomorfologi pesisir pantai dan proses faktor oseanografi yang berpengaruh. Penelitian ini menggunakan metode kasus dengan analisis dinamika proses geomorfologi dan oceanografi yang berpengaruh di daerah penlitian. Data penelitian berupa pasang surut, arus dan sedimen di wilayah pesisir pantai. Hasil penelitian berupa tipe pasang surut Harian Tunggal dengan elevasi muka air Z0 = 55,90; (MSL) 69,14 cm; (HHWL) = 135,48 cm; (LLWL) = 0,78 cm. Gelombang setinggi 0,62 meter dan periode gelombang 4,1 detik. Gelombang datang dari arah Timur Laut akan pecah pecah setinggi 0,81 meter pada kedalaman sebesar 0,78 meter. Gelombang pecah dengan sudut datang 19,22 derajat terhadap garis pantai, akan mengakibatkan kecepatan arus sepanjang pantai 0.98 m/detik. Geomorfologi pesisir terdiri dari pesisir pantai bukit terjal tersusun material volkanik pasir tufaan dan batu gamping klastik dan batu gamping non klastik; pesisir landai/datar tersusun pasir lanauan; pesisir pantai muara sungai tersusun oleh pasir lempungan; pesisir pantai erosi terjadi erosi berm. Proses dinamika geomorfologi dipenaruhi oleh arus longshore yang menyebabkan adanya dominan abrasi di daerah penelitian
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
