ABSTRACT
The magnetic method is a geophysical method based on the measurement of variations in the intensity of the magnetic field on the earth's surface. Research by magnetic methods has been carried out in the Padusan, geothermal prospect area. This study aims to determine the local magnetic field and subsurface structure based on the magnetic properties of rocks. Data acquisition is carried out in an area of 1000 m2 with a distance of each data acquisition point of 100 m forming a grid. After processing the data, the local magnetic field value of the study area is -800 - 1200 nT. Low magnetic field anomalies of -800 - -100 nT are distributed in the northwest to southeast region while high anomalies worth 600 - 1200 nT are divided into 2 areas in the northeast and southwest to the center of the study area. Sub surface lithology of the study area into 4 layers. The first layer is identified as breccias with value of 0.0001 cgs emu. The second layer was identified as breccias and tuffs with value of 0.02000 cgs emu. The third layer was identified as lava with value of 0.0780 cgs emu. The fourth layer was identified as a basalt lava with value of 0.0700 cgs emu. There is a fracture structure in modeling incisions A-A ', B-B', C-C 'and eroded layers on the C-C' incision.
ABSTRAK
Metode magnetik merupakan salah satu metode geofisika yang didasarkan pada pengukuran variasi intensitas medan magnet di permukaan bumi. Penelitian dengan metode magnetik telah dilakukan di daerah prospek panas bumi Padusan. Penelitian ini bertujuan untuk mengetahui medan magnetik lokal dan struktuk bawah permukaan berdasarkan sifat magnetis batuan. Akuisisi data dilakukan pada area seluas 1000 m2 dengan jarak masing-masing titik akuisisi data sebesar 100 m membentuk grid. Setelah dilakukan pemrosesan data, diperoleh nilai medan magnetik lokal daerah penelitian sebesar -800 – 1200 nT. Anomali medan magnetik rendah bernilai -800 – -100 nT tersebar di daerah barat laut ke tenggara sedangkan anomali tinggi bernilai 600 – 1200 nT terbagi menjadi 2 area di timur laut dan barat daya ke tengah area penelitian. Litologi bawah permukaan area penelitian menjadi 4 lapisan. Lapisan pertama di identifikasi sebagai breksi dengan nilai 0.0001 cgs emu. Lapisan kedua di identifikasi sebagai breksi dan tuff dengan nilai 0.02000 cgs emu. Lapisan ketiga di identifikasi sebagai lava dengan nilai 0.0780 cgs emu. Lapisan keempat di identifikasi sebagai lava basalt dengan nilai 0.0700 cgs emu. Terdapat struktur patahan pada pemodelan sayatan A-A', B-B', C-C' dan lapisan terkikis pada sayatan C-C'
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
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
