    SARI Objek penelitian adalah Lapangan “DOFIR” yang merupakan salah satu daerah operasi PT. Chevron Pasific Indonesia, yang terletak di bagian Timur Cekungan Sumatera Tengah. Wilayah operasi ini berjarak kurang lebih 120 km ke arah Timur Laut dari kota Pekanbaru, ibukota Provinsi Riau. Waktu pelaksanaan selama dua bulan enam belas hari, terhitung mulai tanggal 03 Oktober 2012 – 19 Desember 2012. Pada Lapisan “X” Lapangan “DOFIR” terdapat fasies pengendapan yaitu fasies braided channel , pada Lapisan “Y” terdapat dua fasies pengendapan yaitu fasies transgresive channel-fill, dan fasies prograding mouth-bar. Penentuan fasies ini didasarkan pada interpretasi pola elektrofasies pada kurva gamma ray. Berdasarkan interpretasi dan melihat secara teliti Lapisan “X” dan “Y” pada Lapangan “DOFIR” ini memiliki ciri-ciri endapan yang hampir sama dengan model endapan fasies pengendapan yang telah dikemukakan oleh Budianto Toha (1999). Lapisan “X” dan “Y” Lapangan “DOFIR” diendapkan pada sistem estuarine yang dipengaruhi oleh pasang-surut muka air laut ( tidal estuarine ) yang terdiri dari dua asosiasi fasies yaitu asosiasi fasies coarsening upward bioturbated-rippled fine to medium sandstone (funnel shape), finning upward bioturbated-medium to fine sandston (bell shape), dan finning upward bioturbated medium to veryfine sandstone (blocky shape). Kisaran nilai volume shale yang dimiliki oleh Lapisan “X” yaitu 6% - 28%, sedangkan Lapisan “Y” nilai volume shale berkisar antara 28% - 43%. Nilai porositas yang baik terdapat pada lapisan batupasir bersih yang tebal yaitu pada Lapisan “X” dengan nilai porositas berkisar antara 24% - 39% dan nilai saturasi air berkisar antara 7% - 77%, Lapisan “Y” memiliki nilai porositas yang berkisar antara 20% - 30% dengan nilai saturasi air berkisar antara 30% - 78%

    This research was conducted at the lender Layer Farm owned by H. Dofir located in the village Rejotangan Rejotangan Tulungagung subdistrict. The aim was to determine the analysis of financial analysis in laying hens at the DLF Rejotangan Tulungagung subdistrict, It examines some of the financial aspects of the financial analysis used are, Net B/C Ratio, Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (PP) and Switchings Value. Based on the results of the calculation of financial feasibility of the business laying on Dofir Layer Farm then obtained when the initial conditions of business where there has been no increase productivity showed NPV greater than 0, namely Rp 2,359,608,260.73 IRR is greater than the discount rate that is equal to 71 percent, Net B/C of 3.28 is greater than one, PP is shorter than the life of the project is 2 years and 3 months. Business sensitivity analysis is feasible because decrease of production by 26 percent, the price increase of 28.6 percent DOC and feed prices rise by 37 percent NPV indicates value greater than zero, the Net B/C is greater than 1, IRR more greater than the discount rate and the PP before the age of the business end. In the conditions of development of the results obtained from the analysis showed that this business is financially feasible when done business development by improving the productivity of laying chickenKeyword : poultry, financial and business.</jats:p

    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    The 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

    “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 link
    We 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 link
    We 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 text
    We 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
